Background

The existing vertical mill is popular grinding equipment for manufacturing cement powder, compared with a traditional ball milling system, the vertical mill has high milling efficiency, and the power consumption of the vertical mill is only fifty percent to sixty percent of that of the ball mill; in addition, the vertical mill also has the advantages of integrating the processes of crushing, grinding, drying, selecting powder and the like, and greatly simplifying the vertical production process flow. However, when the grinding roller and the grinding disc mutually crush the grinding material when the traditional vertical mill grinds the material, large-particle material is pushed by the grinding roller and is difficult to enter a grinding gap between the grinding roller and the grinding disc; therefore, relatively speaking, the efficiency of grinding large-particle materials is not very high, and in order to enable the large-particle materials to be easily crushed in the grinding process and simultaneously improve the grinding efficiency of the conventional vertical mill, a vertical mill plate capable of grinding the materials with higher efficiency needs to be designed.

A use method of a vertical grinding disc applied to constructional engineering is characterized in that: the grinding device comprises a grinding roller mechanism, a grinding disc mechanism and a supporting rotary disc, wherein the grinding disc mechanism is arranged at one end of the supporting rotary disc; the three grinding roller mechanisms are all positioned on the upper side of the grinding disc mechanism and are uniformly distributed along the circumferential direction; the three grinding roller mechanisms are all matched with the grinding disc mechanism.

The grinding roller mechanism comprises a rotary column, a conical grinding roller, trapezoidal teeth and a tooth lining plate, wherein the conical grinding roller is arranged at one end of the rotary column; a plurality of trapezoidal teeth are uniformly arranged on the outer conical surface of the conical grinding roller along the circumferential direction; the side of each trapezoidal tooth far away from the conical grinding roller is provided with a tooth lining plate.

The grinding disc mechanism comprises a grinding disc body, a trapezoid groove, a trapezoid lining plate, a trapezoid sliding block, a sliding block spring and a trapezoid sliding groove, wherein the grinding disc body is fixedly arranged on the supporting turntable; a plurality of trapezoidal grooves are uniformly formed in the disc surface of the grinding disc body, which is far away from the supporting turntable, along the circumferential direction; each trapezoid groove penetrates through the outer circular surface of the grinding disc body; a trapezoid sliding groove is formed in the disc surface of the grinding disc body between every two adjacent trapezoid grooves; a trapezoidal lining plate is fixedly arranged on the bottom groove surface of each trapezoidal groove; the structure that each ladder type spout was installed is the same, to any one of them ladder type spout: the ladder-shaped sliding block is arranged in the ladder-shaped sliding groove in a sliding fit manner; one end of the sliding block spring is arranged on the bottom groove surface of the trapezoidal sliding groove, and the other end of the sliding block spring is arranged on the trapezoidal sliding block; the slide block spring is positioned in the ladder-shaped sliding groove; one end of the trapezoidal sliding block, which is far away from the sliding block spring, is composed of a sharp corner, two inclined planes and a triangular end face.

The trapezoidal teeth and the tooth lining plates in the grinding roller mechanism are matched with the trapezoidal grooves in the grinding disc body and the trapezoidal lining plates in the trapezoidal grooves.

As a further improvement of the technology, the end of the supporting turntable far away from the grinding table body is connected with a driving mechanism. Then, after the driving mechanism acts, the driving mechanism drives the grinding disc body to rotate through the supporting turntable.

As a further improvement of the technology, the end of the rotary column far away from the conical grinding roller is connected with a pressurizing mechanism. After the pressurizing mechanism acts, the pressurizing mechanism drives the conical grinding roller to move downwards through the rotating column, the trapezoidal teeth and the tooth lining plate move along with the conical grinding roller, and the trapezoidal teeth and the tooth lining plate are matched with the trapezoidal grooves and the trapezoidal lining plate of the grinding disc body to grind cement materials.

As a further improvement of the present technology, the slider spring is a compression spring; when the slide block spring is not compressed, one end of the trapezoidal slide block, which is far away from the slide block spring, extends out of the trapezoidal sliding groove, and two inclined planes on the trapezoidal slide block extend out of the trapezoidal sliding groove.

As a further improvement of the technology, the ratio of the diameter of the end of the conical grinding roller far away from the corresponding rotary column to the diameter of the end of the conical grinding roller connected with the corresponding rotary column is K1; the ratio of the radial distance from the side groove surface close to the center of the grinding disc body in the trapezoid groove to the center of the grinding disc body to the radial distance from the outer circle surface of the grinding disc body to the center of the grinding disc body is K2; k1 equals K2. In order to ensure that adjacent trapezoidal teeth on the conical grinding roller can be completely meshed with adjacent trapezoidal grooves on the grinding disc body in the radial direction in the rotating process of the grinding disc body.

The ladder-shaped lining plate and the tooth lining plate have the effect that the tooth lining plate and the corresponding ladder-shaped lining plate can grind cement material particles into powder reaching the standard through extrusion matching. In addition, in the process of mutually matching and grinding the toothed lining plate and the corresponding trapezoidal lining plate, the toothed lining plate and the trapezoidal lining plate are relatively large in abrasion and can be replaced after being used for a period of time.

After the cement materials fall to the middle position of the grinding disc body, the rotary grinding disc body drives the cement materials to rotate, the cement materials move towards the periphery of the grinding disc body under the action of centrifugal force, part of the cement materials are located on the grinding disc body between the adjacent trapezoid grooves, and the other part of the cement materials can fall in the trapezoid grooves.

The trapezoidal teeth on the conical grinding roller and the trapezoidal grooves on the grinding disc body can be meshed and matched with each other like the meshing of gears; when the trapezoidal teeth enter the trapezoidal grooves to extrude and grind cement materials, the outer conical surface of the conical grinding roller is extruded in a matching way with the upper surface of the grinding disc body between the adjacent trapezoidal grooves, the cement materials on the grinding disc body between the adjacent trapezoidal grooves are extruded, the outer conical surface of the conical grinding roller is not provided with a traditional lining plate, so that the upper surface of the grinding disc body between the adjacent trapezoid grooves and the outer conical surface of the conical grinding roller can cause serious abrasion in the long-time working process, in order to avoid the phenomenon of serious abrasion, therefore, cement materials are not reserved on the upper surface of the grinding disc body between the adjacent trapezoid-shaped grooves, the trapezoid sliding groove is required to be extended out from one end, away from the sliding block spring, of the trapezoid sliding block, the height of the grinding disc body at the position of the adjacent trapezoid-shaped grooves is increased, the probability that the cement materials are taken to the end face, away from the sliding block spring, of the trapezoid sliding block is reduced, and abrasion of the outer conical surface of the conical grinding roller is reduced. In addition, in order to ensure that the ladder-shaped teeth and the ladder-shaped grooves can be normally meshed, the ladder-shaped sliding block needs to be stretched and retracted in the ladder-shaped sliding groove. In order to further reduce the cement materials to be brought to the end face of the trapezoid sliding block far away from the sliding block spring, the sharp corner on the trapezoid sliding block is close to the center of the grinding disc body in design, and the trapezoid sliding block is provided with two inclined planes. After probably dropping the cement material on the triangle-shaped terminal surface, when trapezoidal slider reciprocated, the cement material on the triangle-shaped terminal surface can make the cement material drop in corresponding trapezoidal groove along two inclined planes of triangle-shaped terminal surface department because of the motion of trapezoidal slider. In addition, in the process of extruding and grinding the cement materials, the cement materials can be brought to the inclined plane and the triangular end face of the corresponding trapezoidal sliding block, and at the moment, the cement materials can easily slide into the corresponding trapezoidal groove by utilizing the inclined plane and the up-and-down movement. In order to prevent the cement material from remaining on the end of the trapezoidal slider away from the slider spring, the design that the end of the trapezoidal slider away from the slider spring is composed of a sharp corner, two inclined surfaces and a triangular end surface is necessary.

Trapezoidal tooth and tooth welt in the above-mentioned grinding roller mechanism cooperate with trapezoidal groove in the mill table body and the trapezoidal welt in the trapezoidal groove: the trapezoidal teeth and the tooth lining plates can be meshed like gears, the trapezoidal teeth and the tooth lining plates enter the corresponding trapezoidal grooves through meshing, and the tooth lining plates can be matched with the corresponding trapezoidal lining plates through extrusion to grind cement materials.

When the vertical grinding disc is not in operation, the three grinding roller mechanisms are positioned at the upper side of the grinding disc body, and the trapezoidal teeth in the grinding roller mechanisms are not in meshing relationship with the trapezoidal grooves on the grinding disc body. The slider spring is not compressed, and the trapezoidal spout is stretched out to the one end that slider spring was kept away from to the trapezoidal slider, and two inclined planes on the trapezoidal slider stretch out the trapezoidal spout.

When the vertical grinding disc of the invention grinds cement materials, the driving mechanism acts and drives the grinding disc body to rotate through the supporting turntable; then, the material conveying mechanism on the upper side of the grinding disc body drops the cement material to the middle position of the grinding disc body; then the rotating grinding disc body drives the cement materials to rotate, and the cement materials move to the periphery of the grinding disc body under the action of centrifugal force; because the one end that the slider spring was kept away from to the trapezoidal slider is to the hindrance detention effect of cement material, the cement material in the trapezoidal groove can not the adhesion keep away from the slider spring at the trapezoidal slider on one end. When the cement materials are ground into qualified particles, or the cement materials are not yet ground into the particles, and the particles of the three types of cement materials fall off from the grinding disc body, the powder selecting mechanism screens out the qualified cement materials, and recycles the unqualified cement materials and the cement materials which are not yet ground.

The cement material grinding process by the vertical grinding disc: the pressurizing mechanism acts and drives the conical grinding roller to move downwards through the rotating column; the trapezoidal teeth and the tooth lining plates in the grinding roller mechanism move along with the conical grinding roller, and the trapezoidal teeth and the tooth lining plates enter the corresponding trapezoidal grooves. Due to the rotation of the grinding disc body, the grinding disc body can drive the trapezoidal teeth and the tooth lining plates to rotate around the axis of the conical grinding roller in the grinding roller mechanism; thus, the trapezoidal teeth on the conical grinding roller and the trapezoidal grooves on the grinding disc body can be meshed and matched with each other like the meshing of gears. The gear lining plate is driven by the trapezoidal teeth to enter the trapezoidal grooves, and the cement materials are ground by extruding the trapezoidal lining plate, the outer conical surface of the conical grinding roller can be extruded in a matching manner with the trapezoidal sliding block surface between the adjacent trapezoidal grooves, the trapezoidal sliding block moves towards the bottom of the trapezoidal sliding groove under the extrusion force, and the sliding block spring is compressed.

Compared with the efficiency of grinding cement materials by a traditional conical grinding roller, the invention mainly utilizes the trapezoidal teeth and the corresponding trapezoidal grooves to generate meshing extrusion to grind the cement materials, and because the cement materials are all in the trapezoidal grooves, cement material particles cannot be pushed out of the trapezoidal grooves by the trapezoidal teeth when the cement materials in the trapezoidal grooves are ground by extrusion; in addition, as the trapezoidal teeth can be meshed with the corresponding arc-shaped grooves like gears to enter the corresponding arc-shaped grooves to extrude and grind the cement materials, the cement materials can completely exist between the trapezoidal teeth and the trapezoidal lining plates of the corresponding trapezoidal grooves, and all the cement materials with different sizes can be ground by utilizing the meshing extrusion generated by the trapezoidal teeth and the corresponding trapezoidal grooves; therefore, the phenomenon that when the traditional conical grinding roller grinds cement materials, large-particle materials are pushed by the grinding roller and cannot easily enter a grinding gap between the grinding roller and the grinding disc is avoided. Therefore, the invention can ensure that the efficiency of grinding the cement material in the trapezoid groove is higher than that of grinding the cement material by the traditional conical grinding roller by grinding the cement material by using the method like the gear meshing principle.

When the trapezoidal sliding block is not extruded by the corresponding conical grinding roller any more, the trapezoidal sliding block moves away from the bottom of the trapezoidal sliding groove to reset under the reset force of the sliding block spring. The trapezoidal teeth on the conical grinding roller are engaged with the next trapezoidal groove to extrude to grind the cement material.

Compared with the traditional millstone technology, the invention utilizes the trapezoidal teeth to be meshed into the corresponding arc-shaped grooves like the gear meshing to extrude and grind the cement materials, thereby achieving the efficiency higher than that of the traditional conical grinding roller directly extruding and grinding the cement materials with the millstone. In order to prevent the abrasion caused in the engineering process of the upper surface of a grinding disc body between adjacent trapezoid grooves and the outer conical surface of a conical grinding roller after cement materials are left on one end, far away from a sliding block spring, of the trapezoid sliding block, the design that one end, far away from the sliding block spring, of the trapezoid sliding block is composed of a sharp corner, two inclined surfaces and a triangular end surface is necessary. The invention has simple structure and better use effect.

As shown in fig. 3, 4 and 8, the grinding disc mechanism 4 includes a grinding disc body 6, a trapezoidal groove 7, a trapezoidal liner 8, a trapezoidal slider 9, a slider spring 10 and a trapezoidal sliding groove 12, as shown in fig. 1, wherein the grinding disc body 6 is fixedly mounted on the supporting turntable 5; as shown in fig. 3 and 5, a plurality of trapezoidal grooves 7 are uniformly arranged on the surface of the grinding disc body 6 away from the supporting turntable 5 along the circumferential direction; each trapezoid groove 7 penetrates through the outer circular surface of the grinding disc body 6; as shown in fig. 5 and 6, a trapezoidal sliding groove 12 is formed on the disc surface of the grinding disc body 6 between two adjacent trapezoidal grooves 7; as shown in fig. 6 and 7, a trapezoidal lining plate 8 is fixedly arranged on the bottom groove surface of each trapezoidal groove 7; each ladder runner 12 is mounted in the same structure, and for any one of the ladder runners 12: as shown in fig. 4 and 8, the ladder-shaped sliding block 9 is installed in the ladder-shaped sliding groove 12 in a sliding fit manner; one end of a slider spring 10 is arranged on the bottom groove surface of the trapezoidal sliding groove 12, and the other end is arranged on the trapezoidal slider 9; the slider spring 10 is positioned in the ladder-shaped chute 12; the end of the trapezoidal slider 9 remote from the slider spring 10 is formed by a sharp corner 27, two inclined surfaces 28 and a triangular end surface 29.

The trapezoidal teeth 32 and the tooth lining plates 33 in the grinding roller mechanism 1 are matched with the trapezoidal grooves 7 in the grinding disc body 6 and the trapezoidal lining plates 8 in the trapezoidal grooves 7.

One end of the supporting turntable 5, which is far away from the grinding turntable body 6, is connected with a driving mechanism. Then, after the driving mechanism acts, the driving mechanism drives the grinding disc body 6 to rotate through the supporting turntable 5.

The end of the rotary column 30 remote from the conical grinding roller 31 is connected to a pressurizing mechanism. Then after the pressurizing mechanism is operated, the pressurizing mechanism drives the conical grinding roller 31 to move downwards through the rotating column 30, the trapezoidal teeth 32 and the tooth lining plates 33 follow the conical grinding roller 31 to move, and the trapezoidal teeth 32 and the tooth lining plates 33 are matched with the trapezoidal grooves 7 and the trapezoidal lining plates 8 of the grinding disc body 6 to grind the cement materials.

The slider spring 10 is a compression spring; when the slider spring 10 is not compressed, one end of the ladder slide 9 away from the slider spring 10 extends out of the ladder slide groove 12, and two inclined surfaces 28 on the ladder slide 9 extend out of the ladder slide groove 12.

As shown in fig. 9 and 10, the ratio of the diameter of the conical grinding roller 31 at the end far from the corresponding rotary column 30 to the diameter of the conical grinding roller 31 at the end connected with the corresponding rotary column 30 is K1; as shown in fig. 3, the ratio of the radial distance from the side groove surface of the trapezoid groove 7 close to the center of the grinding disc body 6 to the radial distance from the outer circumferential surface of the grinding disc body 6 to the center of the grinding disc body 6 is K2; k1 equals K2. This design ensures that, during rotation of the grinding disc body 6, adjacent trapezoidal teeth 32 of the conical grinding roller 31 can in turn engage completely in the radial direction of the adjacent trapezoidal grooves 7 of the grinding disc body 6.

The ladder-shaped lining plate 8 and the tooth lining plate 33 have the function that the tooth lining plate 33 and the corresponding ladder-shaped lining plate 8 can grind cement material particles into powder reaching the standard through extrusion matching. In addition, in the process of mutually matching and grinding the toothed lining plate 33 and the corresponding trapezoidal lining plate 8, the toothed lining plate 33 and the trapezoidal lining plate 8 are relatively large in abrasion, and can be replaced after being used for a period of time.

After the cement materials fall to the middle position of the grinding disc body 6, the rotating grinding disc body 6 drives the cement materials to rotate, the cement materials move towards the periphery of the grinding disc body 6 under the action of centrifugal force, part of the cement materials are located on the grinding disc body 6 between the adjacent trapezoid grooves 7, and the other part of the cement materials can fall in the trapezoid grooves 7.

The trapezoidal teeth 32 on the conical grinding roller 31 and the trapezoidal grooves 7 on the grinding disc body 6 can be meshed with each other like gear meshing; when the trapezoidal teeth 32 enter the trapezoidal grooves 7 to extrude and grind cement materials, the outer conical surface of the conical grinding roller 31 is extruded in a matching manner with the upper surface of the grinding disc body 6 between the adjacent trapezoidal grooves 7, the cement materials on the grinding disc body 6 between the adjacent trapezoidal grooves 7 are extruded, and no traditional lining plate exists on the outer conical surface of the conical grinding roller 31, so that the upper surface of the grinding disc body 6 between the adjacent trapezoidal grooves 7 and the outer conical surface of the conical grinding roller 31 can cause serious abrasion in the long-time working process, in order to avoid the phenomenon of serious abrasion, the upper surface of the grinding disc body 6 between the adjacent trapezoidal grooves 7 is required to be not provided with the cement materials any more, that is why one end of the trapezoidal sliding block 9 far away from the sliding block spring 10 needs to be designed to extend out the trapezoidal sliding groove 12, the height of the grinding disc body 6 at the position of the adjacent trapezoidal groove 7 is increased, and the probability that the cement materials are brought to the end face of the trapezoidal, the wear of the outer conical surface of the conical grating roller 31 is reduced. In addition, in order to ensure that the ladder teeth 32 and the ladder grooves 7 are normally engaged, the ladder slide 9 needs to be extended and retracted in the ladder slide groove 12. In order to further reduce the cement materials brought to the end face, far away from the slider spring 10, of the trapezoidal sliding block 9, the sharp corner 27 on the trapezoidal sliding block 9 is designed to be close to the center of the grinding disc body 6, and the trapezoidal sliding block 9 is provided with two inclined faces 28, so that when the cement materials in the center of the grinding disc body 6 move towards the periphery of the grinding disc body 6 and fall on one end, far away from the slider spring 10, of the trapezoidal sliding block 9, the cement materials are firstly separated by the sharp corner 27 and guided to the corresponding inclined face 28, at this time, the cement materials easily slide down from the inclined face 28 suitable for the cement materials to fall down and enter the corresponding trapezoidal groove 7, and the triangular end face 29 on the trapezoidal sliding block 9 is not easy to fall on the cement materials. When the trapezoidal sliding blocks 9 move up and down after cement materials possibly fall on the triangular end surfaces 29, the cement materials on the triangular end surfaces 29 can fall into the corresponding trapezoidal grooves 7 along the two inclined surfaces 28 at the triangular end surfaces 29 due to the movement of the trapezoidal sliding blocks 9. In addition, during the process of extruding and grinding the cement materials, the cement materials are brought to the inclined surfaces 28 and the triangular end surfaces 29 of the corresponding trapezoidal sliding blocks 9, and at the moment, the cement materials are easy to slide into the corresponding trapezoidal grooves 7 by utilizing the inclined surfaces 28 and the up-and-down movement. As described above, in order to prevent the cement material from remaining on the end of the ladder slide 9 away from the slide spring 10, a design in which the end of the ladder slide 9 away from the slide spring 10 is formed of the sharp corner 27, the two inclined surfaces 28, and the triangular end surface 29 is necessary.

The trapezoidal teeth 32 and the tooth lining board 33 in the grinding roller mechanism 1 are matched with the trapezoidal groove 7 in the grinding disc body 6 and the trapezoidal lining board 8 in the trapezoidal groove 7: the trapezoidal teeth 32 and the tooth liner plates 33 can be engaged like gears, the trapezoidal teeth 32 and the tooth liner plates 33 enter the corresponding trapezoidal grooves 7 through engagement, and the tooth liner plates 33 can be matched with the corresponding trapezoidal liner plates 8 through extrusion to grind cement materials.

While the ladder-shaped teeth 32 and the ladder-shaped grooves 7 in the other figures are only simple schematic diagrams and do not have the shapes of teeth and tooth grooves in the normal gear meshing, the principle schematic diagram of the grinding of the ladder-shaped teeth 32 and the ladder-shaped grooves 7 is shown in fig. 11.
