The vertical fixed mounting of base plate lower surface has driving motor, and the vertical fixedly connected with of driving motor's output runs through the first installation axle of base plate. And a gear meshed with the outer gear ring is fixedly arranged on the first mounting shaft. The upper surface of the base plate is vertically and rotatably provided with a second installation shaft which coincides with the axis of the working barrel, and a plurality of trays are uniformly and fixedly arranged on the second installation shaft from top to bottom. Except for the tray at the lowest layer, the blanking groove is uniformly formed on the rest trays around the second mounting shaft. The inner wall of the working barrel is provided with a spiral material guide plate from top to bottom. A material receiving box with an opening on the top surface is arranged on the upper surface of the base plate corresponding to the bottom end of the material guide plate. The upper surface of the base plate is vertically and fixedly provided with a mounting rod outside the working barrel. The top of the mounting rod is fixedly provided with a horizontal plate, and the horizontal plate is provided with a water delivery mechanism. The first mounting shaft and the gear are driven to rotate by the driving motor, and the gear drives the outer gear ring, the mounting cylinder and the working cylinder to rotate. The raw meal powder is conveyed to the tray on the uppermost layer through the existing material conveying equipment such as a pipeline, and the tray is driven to rotate by rotating the second mounting shaft. Partial raw meal powder on the upper surface of the tray slides to the edge of the tray under the action of centrifugal force and is separated from the tray, and the raw meal powder separated from the tray impacts the inner wall of the working barrel and falls to the upper surface of the material guide plate along the inner wall of the working barrel.

And water drops are conveyed to the top of the material guide plate through the water conveying mechanism, fall to the top of the material guide plate and then roll downwards along the upper surface of the material guide plate in a spiral shape, and gradually adsorb raw meal powder on the upper surface of the material guide plate to form raw meal balls. The raw material balls fall into the material receiving box after being separated from the material guide plate.

The water delivery mechanism comprises a water storage tank with an opening on the top surface and fixedly installed at the end part of the horizontal plate. The bottom plate of the water storage tank is provided with a water outlet in a penetrating way, and the inside of the water storage tank is provided with an air groove. One end of the air groove is positioned on the upper surface of the water storage tank bottom plate and is vertically matched with a lifting rod in a sliding manner, and a water blocking block matched with the water outlet is fixedly installed at the top of the lifting rod. The inside sliding seal of storage water tank cooperates the horizontal lifter plate. A water inlet and an air inlet are formed in the lifting plate in a penetrating mode, and a sealing plug is installed at the position of the water inlet. A sealing ring is horizontally and fixedly arranged on the inner wall of the air inlet, and a guide rod is vertically and fixedly arranged on the lower surface of the sealing ring. The guide rod is vertically matched with a sealing block which is matched with the sealing ring in a sliding way. A supporting sheet is fixedly installed at the bottom end of the guide rod, and a first spring sleeved on the guide rod is fixedly connected between the supporting sheet and the sealing block. The top of the inner side wall of the water storage tank is fixedly provided with a pressure bearing sheet, and a second spring is fixedly connected between the pressure bearing sheet and the lifting plate vertically. The periphery of the lifting plate is embedded with a first magnet block, and a second magnet block corresponding to the first magnet block in position is vertically matched in the air groove in a sliding manner. The bottom surface of the second magnet block is fixedly connected with a first sliding block which is in sealing sliding fit with the air groove. The other end of the air groove is positioned on the outer side wall of the water storage tank. An L-shaped rod is fixedly arranged on the upper surface of the lifting plate, and a vertical rod penetrating through the horizontal plate is fixedly arranged at the end part of the horizontal section of the L-shaped rod. The supporting plate is horizontally and fixedly installed at the top of the vertical rod, the elastic telescopic rod is vertically and fixedly installed on the upper surface of the horizontal plate, and the top end of the elastic telescopic rod is fixedly connected to the lower surface of the supporting plate. And the bottom end of the vertical rod is provided with a third magnet block. And a fourth magnet block is arranged on the upper surface of the working barrel corresponding to the third magnet block. Water is injected into the water storage tank through the water inlet, and then the water inlet is sealed through the sealing plug. In the rotating process of the working barrel, after the fourth magnet block reaches the position corresponding to the third magnet block, attractive force is generated between the fourth magnet block and the third magnet block, the third magnet block drives the vertical rod, the support plate and the L-shaped rod to synchronously move downwards under the action of the attractive force, and the support plate compresses the elastic telescopic rod. The L-shaped rod pushes the lifting plate to descend to extrude water in the water storage tank, and the second spring is stretched. The lifting plate drives the first magnet block to synchronously descend in the descending process, and the first magnet block drives the second magnet block and the first sliding block to downwards move along the air groove due to attraction between the first magnet block and the second magnet block. The first sliding block extrudes air in the air groove, the air pressurized in the air groove pushes the lifting rod to ascend, and the lifting rod pushes the water blocking block to ascend; the water blocking block is attached to the water outlet in an initial state, at the moment, the water blocking block is separated from the water outlet, and water in the water storage tank flows out of a gap between the water blocking block and the water outlet and drops to the upper surface of the material guide plate. Along with the working barrel continues to rotate, after the fourth magnet block leaves the position corresponding to the third magnet block, attractive force between the fourth magnet block and the third magnet block disappears, and the resilience force of the second spring and the elastic telescopic rod drives the vertical rod, the third magnet block, the supporting plate, the L-shaped rod and the lifting plate to ascend and reset. The lifting plate drives the first magnet block, the second magnet block and the first sliding block to move upwards in the lifting process. The air pressure in the air groove enables the lifting rod to drive the water blocking block to descend, and the water blocking block is attached to the water outlet again. In the ascending process of the lifting plate, the air pressure below the lifting plate is reduced, and the air outside the water storage tank overcomes the elastic action of the first spring to push the sealing block to move downwards under the action of the air pressure. The sealing block is separated from the sealing ring, and outside air enters the area below the lifting plate in the water storage tank through the gap between the sealing block and the sealing ring after passing through the air inlet.

As a preferable technical scheme of the invention, the material receiving box is detachably arranged on the upper surface of the base plate, and the sponge layer is fixedly arranged at the bottom of the inner surface of the material receiving box, so that the collision force generated when raw material balls fall to the bottom of the inner surface of the material receiving box is reduced, and the raw material balls are prevented from being damaged. After the material receiving box is filled with the raw material balls, the material receiving box is detached from the upper surface of the base plate, and the raw material balls are poured out without taking out the raw material balls manually.

As a preferred technical solution of the present invention, a first belt wheel is fixedly mounted on the top of the first mounting shaft, and a second belt wheel is fixedly mounted on the top of the second mounting shaft. The first belt wheel and the second belt wheel are connected through a transmission belt. Drive first band pulley through first installation axle and drive to drive second band pulley and second installation axle through the drive belt and rotate, need not the manual work and rotate second installation axle, improved machining efficiency, saved the manpower.

As a preferable technical scheme of the invention, the inner side wall of the water outlet is a conical surface with the radius gradually reduced from top to bottom, so that water in the water storage tank forms water drops which are gathered together after passing through the water outlet.

As a preferred technical scheme of the invention, a spiral baffle plate is vertically and fixedly installed on the outer surface of the guide plate, so as to ensure that raw meal on the upper surface of the guide plate cannot fall from the edge of the guide plate.

As a preferred technical scheme of the invention, a plurality of horizontal grooves which horizontally penetrate through the working barrel are formed in the inner side wall of the working barrel along the material guide plate. A sliding rod is in sliding fit in the horizontal groove. The inner end of the sliding rod is fixedly connected with a second sliding block which is in sliding sealing fit with the horizontal groove. The outer end of the sliding rod is fixedly provided with a fifth magnet block. And a plurality of sixth magnet blocks corresponding to the fifth magnet blocks are arranged on the mounting rod. The holding tank has been seted up to the level on the horizontal groove lateral wall. And a third sliding block in sliding fit with the accommodating groove is fixedly arranged on the sliding rod. And a third spring is horizontally and fixedly connected between the third sliding block and the end surface of the accommodating groove. In the rotating process of the working barrel, when the fifth magnet block and the sixth magnet block enter corresponding positions, mutual repulsion is generated between the fifth magnet block and the sixth magnet block. The fifth magnet block pushes the sliding rod to slide in the horizontal groove under the action of mutual repulsion, the sliding rod drives the third sliding block to slide in the accommodating groove, and the third sliding block stretches the third spring. The slide bar promotes the second slider when sliding in the horizontal groove and slides in the horizontal inslot synchronization, and the horizontal groove is released with the air of horizontal inslot to the second slider, and the raw meal powder of stock guide upper surface is blown to the air current that produces, avoids the raw meal powder to pile up the blocking. When the fifth magnet block leaves the position corresponding to the sixth magnet block, the mutual repulsion force between the fifth magnet block and the sixth magnet block disappears; the third sliding block, the sliding rod and the second sliding block are reset under the action of resilience force of the third spring, and air outside the horizontal groove enters the horizontal groove. Along with the continuous rotation of working barrel, the air in the horizontal groove exchanges with outside air repeatedly to make the air current continuously blow the raw meal powder of stock guide upper surface, avoided the raw meal powder to pile up the blocking.

The bottom surface of the second magnet 1516 is fixedly connected with a first slider 1517 which is in sealing sliding fit with the air groove 153. The other end of the air slot 153 is located on the outer side wall of the water storage tank 151. An L-shaped rod 1518 is fixedly arranged on the upper surface of the lifting plate 156, and a vertical rod 1519 penetrating through the horizontal plate 14 is fixedly arranged at the end part of the horizontal section of the L-shaped rod 1518. The top of the vertical rod 1519 is horizontally and fixedly provided with a support plate 1520, the upper surface of the horizontal plate 14 is vertically and fixedly provided with an elastic telescopic rod 1521, and the top end of the elastic telescopic rod 1521 is fixedly connected to the lower surface of the support plate 1520. The bottom end of the vertical rod 1519 is provided with a third magnet block 1522. A fourth magnet block 16 is mounted on the upper surface of the work cylinder 3 at a position corresponding to the third magnet block 1522.

The water delivery mechanism 15 has the following specific working process: water is filled into the water storage tank 151 through the water inlet 157, and then the water inlet 157 is sealed by the sealing plug 159. In the rotation process of the working barrel 3, when the fourth magnet block 16 reaches the position corresponding to the third magnet block 1522, an attractive force is generated between the fourth magnet block and the third magnet block 1522, the third magnet block 1522 drives the vertical rod 1519, the support plate 1520 and the L-shaped rod 1518 to synchronously move downwards under the action of the attractive force, and the support plate 1520 compresses the elastic expansion rod 1521. The L-shaped lever 1518 pushes the lifting plate 156 to descend to press the water in the water storage tank 151, and the second spring 1514 is elongated. The lift plate 156, when it descends, drives the first magnet 1515 to descend synchronously, and the first magnet 1515 drives the second magnet 1516 and the first slider 1517 to move down along the air slot 153 due to the attraction between the first magnet 1515 and the second magnet 1516. The first sliding block 1517 presses air in the air groove 153, the air pressed in the air groove 153 pushes the lifting rod 154 to rise, and the lifting rod 154 pushes the water blocking block 155 to rise; the water blocking block 155 is attached to the water outlet 152 in an initial state, at this time, the water blocking block 155 is separated from the water outlet 152, and water in the water storage tank 151 flows out from a gap between the water blocking block 155 and the water outlet 152 and drops onto the upper surface of the material guide plate 11. As the working barrel 3 continues to rotate, after the fourth magnet block 16 leaves the position corresponding to the third magnet block 1522, the attraction force between the fourth magnet block and the third magnet block disappears, and the vertical rod 1519, the third magnet block 1522, the support plate 1520, the L-shaped rod 1518 and the lifting plate 156 are driven by the resilience force of the second spring 1514 and the elastic telescopic rod 1521 to ascend and return. The lifting plate 156 drives the first magnet 1515, the second magnet 1516, and the first slider 1517 to move upward during the lifting process. The air pressure in the air groove 153 causes the lifting rod 154 to drive the water blocking block 155 to descend, and the water blocking block 155 is attached to the water outlet 152 again. When the lifting plate 156 rises, the air pressure below the lifting plate 156 is reduced, and the air outside the water tank 151 pushes the sealing block 1512 to move downwards under the action of the air pressure and against the elastic force of the first spring 1513. The sealing block 1512 is separated from the sealing ring 1510, and outside air enters the water storage tank 151 through the gap between the sealing block 1512 and the sealing ring 1510 after passing through the air inlet 158.

The first belt wheel 18 is fixedly mounted on the top of the first mounting shaft 6, and the second belt wheel 19 is fixedly mounted on the top of the second mounting shaft 8. The first pulley 18 and the second pulley 19 are connected by a belt 20. Drive first band pulley 18 through first installation axle 6 and drive to drive second band pulley 19 and second installation axle 8 through drive belt 20 and rotate, need not the manual work and rotate second installation axle 8, improved machining efficiency, saved the manpower.

A plurality of horizontal grooves 22 which horizontally penetrate through the working barrel 3 are arranged on the inner side wall of the working barrel 3 along the material guide plate 11. A slide bar 23 is slidably fitted in the horizontal groove 22. The inner end of the sliding rod 23 is fixedly connected with a second sliding block 24 which is matched with the horizontal groove 22 in a sliding and sealing way. The outer end of the sliding rod 23 is fixedly provided with a fifth magnet block 25. The mounting rod 13 is provided with a plurality of sixth magnet blocks 26 corresponding to the fifth magnet blocks 25 in position. The side wall of the horizontal groove 22 is horizontally provided with an accommodating groove 27. A third slide block 28 which is in sliding fit with the accommodating groove 27 is fixedly mounted on the sliding rod 23. A third spring 29 is horizontally and fixedly connected between the third slide block 28 and the end surface of the accommodating groove 27. When the fifth magnet 25 and the sixth magnet 26 enter the corresponding positions during the rotation of the work drum 3, a repulsive force is generated therebetween. The fifth magnet block 25 pushes the sliding rod 23 to slide in the horizontal groove 22 under the action of the repulsive force, the sliding rod 23 simultaneously drives the third sliding block 28 to slide in the accommodating groove 27, and the third sliding block 28 stretches the third spring 29. When the sliding rod 23 slides in the horizontal groove 22, the second sliding block 24 is pushed to synchronously slide in the horizontal groove 22, the second sliding block 24 pushes the air in the horizontal groove 22 out of the horizontal groove 22, and the generated air flow blows the raw meal on the upper surface of the material guide plate 11, so that the raw meal is prevented from being accumulated into blocks. When the fifth magnet block 25 is separated from the position corresponding to the sixth magnet block 26, the mutual repulsive force therebetween disappears; the third slider 28, the slide rod 23 and the second slider 24 are restored by the resilient force of the third spring 29, and air outside the horizontal groove 22 enters the horizontal groove 22. With the continuous rotation of the working barrel 3, the air in the horizontal groove 22 is repeatedly exchanged with the outside air, so that the raw meal on the upper surface of the material guide plate 11 is continuously blown by the airflow, and the raw meal is prevented from being accumulated into blocks.

The working process of the composite portland cement preparation device in the embodiment is as follows: the raw meal powder is conveyed to the tray 9 at the uppermost layer through the existing material conveying equipment such as a pipeline, and the tray 9 is driven to rotate by rotating the second mounting shaft 8. Partial raw meal powder on the upper surface of the tray 9 slides to the edge of the tray 9 under the action of centrifugal force and is separated from the tray 9, and the raw meal powder separated from the tray 9 impacts the inner wall of the working barrel 3 and falls to the upper surface of the material guide plate 11 along the inner wall of the working barrel 3. Part of the raw meal powder on the upper surface of the tray 9 passes through the blanking groove 10 and falls to the upper surface of the lower tray 9. The water droplets are conveyed to the top of the material guide plate 11 by the water conveying mechanism 15, fall to the top of the material guide plate 11 and then spirally roll downwards along the upper surface of the material guide plate 11, and gradually adsorb the raw meal on the upper surface of the material guide plate 11 to form raw meal balls. The raw material balls fall into a material receiving box 12 after being separated from the material guide plate 11.
