According to an aspect of the embodiment of the present invention, a homogenizing and flow stabilizing system is provided, the homogenizing and flow stabilizing system comprises a silo body 1 and a roller press 9 located at the bottom of the silo body 1, material particles are discharged into the silo body 1 through a discharging pipe 7 installed at the top of the silo body 1, the material particles with different particle size intervals have different quality in the material particles, so that the material particles falling into a roll gap 92 are prone to have deviation at two sides of the roll gap 92 due to uneven particle size distribution, and the important technical problems to be solved in the present invention include the following:

1: the material particles falling into the roller gap 92 are uniformly distributed, and the extrusion effect of the roller press is prevented from being reduced due to the roller gap deviation of the roller gap 92 at the two ends;

2: if the roll gap deviation exists, the self-correction of the roll gap 92 is realized through control, so that the use effect of the roll squeezer 9 is ensured.

In practice, the material particles generally charged into the bin 1 include a plurality of interval particle sizes, and the small-diameter interval particles 13 and the large-diameter interval particles 14 are used instead of the illustrated particles, but the material particles are not limited to the two types of interval particles, and the size range of the interval particles is not limited.

Therefore, the invention provides a homogenizing and flow stabilizing system and a control method, which are concretely as follows;

according to an aspect of the embodiment of the present invention, there is provided a homogenizing and flow stabilizing system, which comprises a bin 1 and a roller press 9, wherein the bin 1 has a feeding pipe 7 disposed above the bin, the feeding pipe 7 includes a vertically disposed feeding pipe 71 and a discharging pipe 73 mounted at one end of the feeding pipe 71 and having a free end, it should be noted that, above the bin 1 where the feeding pipe is disposed, one end of the feeding pipe extends to the outside of the top of the bin 1 for feeding particles of a material, the other end of the feeding pipe is disposed in the discharging chamber 11 of the bin 1, and the feeding pipe 71 is connected to the discharging pipe 73 having an adjustable angle, as will be understood by those skilled in the art, the discharging pipe 73 and the feeding pipe 71 are connected to form a whole, and the discharging pipe 73 rotates through an external force applying member, in practice, the discharging pipe 73 as a free end can rotate on the same plane as the vertical plane of the feeding pipe 71, namely, the end part of the discharge pipe 73 is taken as the center of the rotation circle to rotate; it should be emphasized that, in the implementation, the feeding pipe 71 is used for guiding the material particles to enter the discharging pipe 73, and at the same time, the feeding pipe 71 can realize circumferential rotation of its own body, and the circumferential rotation can drive the discharging pipe 73 to make circumferential motion, and at the same time, the discharging pipe 73 makes rotational motion with the connecting end of the feeding pipe 71 as a circle center, and in the process of throwing the material particles, the feeding pipe 71 rotates and the discharging pipe 73 rotates, so that the following functions exist:

1: the rotation of inlet pipe 71 drives discharging pipe 73 and is circular motion, and the effect of accelerating when discharging material granule can be realized, and the skilled person in the art can understand, and the effect can help the material granule to shed more distant place with higher speed, and its level of shedding back material granule is shed displacement and initial velocity positive correlation, promptly with the rotation speed positive correlation of inlet pipe 71, and this inlet pipe 71 be connected with drive assembly, can implement the control of rotation speed through drive assembly, in the implementation, can accomplish the control to shedding material initial velocity through the rotation speed of control inlet pipe 71 to play the differentiation effect of the material granule of the different interval particle size distributions of the shedding horizontal distance of control material granule and control. This differentiation effect granule is understood as, the granule of different particle size interval distribution because the differentiation of weight differentiation, can realize the differentiation of horizontal distance at the throwing in-process of the same initial velocity, and the material granule horizontal throwing distance that the quality is heavier is far away, and the material granule horizontal throwing distance that the quality is lighter is nearer. As shown in fig. 2, in the illustration, the horizontal displacement distance of the large-diameter interval particles 14 is greater than that of the small-diameter interval particles 13 in the process of throwing the small-diameter interval particles 13 and the large-diameter interval particles 14. Meanwhile, the rotation of the feeding pipe 71 can also drive the discharging pipe 73 to make a circular motion and stop at any position on the circumference, and when the discharging pipe 73 is controlled to rotate to a certain circumferential angle by the transmission assembly, the stopping position control of the discharging pipe 73 can be completed.

2: the discharging pipe 73 rotates by taking the end part of the feeding pipe 71 as a rotation center, so that the radial position control in the circumferential radial direction of the discharging pipe 73 can be realized, the rotation angle of the discharging pipe 73 preferably adopted by the invention is 0-90 degrees, and a person skilled in the art can understand that when the discharging pipe 73 rotates by taking the end part of the feeding pipe 71 as a circle, the smaller the rotation angle is, the smaller the horizontal throwing distance of the material particles after being thrown is, and the following two states exist at the same time:

the rotation angle is set to be alpha,

when α is 0 °, referring to fig. 3, at this time, since the discharging pipe 73 and the feeding pipe 71 are located on the same vertical axis, that is, the discharging pipe 73 does not have an initial velocity of horizontal ejection, the material particles ejected with the mixture of the small diameter interval particles 13 and the large diameter interval particles 14 are vertically ejected, the radius of the ejected material particles is diffused, and a circular dispersed particle group is formed in the blanking area, and the small diameter interval particles 13 and the large diameter interval particles 14 in the dispersed particle group are uniformly distributed.

When alpha is more than 0 and less than or equal to 90 degrees, referring to fig. 2, the horizontal displacement distance of the particles 14 in the large-diameter interval is larger than that of the particles 13 in the small-diameter interval when the particles 13 in the small-diameter interval and the particles 14 in the large-diameter interval are sprinkled.

The roller press 9 is provided with two rollers 91, a roller gap 92 for extruding material particles is formed between the two rollers 91, meanwhile, the roller gap 92 is positioned right below the discharge port 12, the central point of the roller gap 92 and the central point of the discharge port 12 are both positioned on the central axis of the feeding pipe 71, and the arrangement is favorable for uniform distribution of the material particles falling into the roller gap 92 during the periodic discharge process of the discharge pipe 7. It should be noted that, in the present embodiment, the material particle distribution is controlled by controlling the discharging pipe 7, a detecting device for detecting the roller gap 92 at the two ends of the roller 91 is installed on the roller press 9, the detecting device uploads the real-time detection information of the roller gap 92 to the control device, and the control device controls the rotation of the feeding pipe 71 and the rotation of the discharging pipe 73 in real time according to the roller gap deviation. In general, it is considered that the roller 91 is provided with the detection probe 101, the detection probe 101 is electrically connected to the detector 10, and the detector 10 uploads real-time detection information.

The core of the invention lies in that the effect of throwing the particles in different particle size intervals to a required position is achieved by controlling the autorotation of the feeding pipe 71 and the rotation of the discharging pipe 73 and according to different throwing distances of the material particles with different weights, and the self-correction of the roll gap 92 is realized by the material particles with different positions after throwing.

As shown in fig. 1, 4, 5 and 6, in fig. 1, a material particle group 15 which is dynamically stacked after being sprinkled is formed at the bottom of the blanking chamber 11 of the bin body 1, and it can be understood by those skilled in the art that after the sprinkling is controlled, the particles 13 in the small-diameter section and the particles 14 in the large-diameter section in the material particle group 15 are uniformly distributed, that is, after falling into the roller gap 92, the extrusion effect without the roller gap deviation can be achieved, and the extrusion effect of the roller press 9 is optimal at this time. The problem to be solved by the present invention is that once the material particle group 15 loses the dynamic balance of the uniform distribution of the small-diameter interval particles 13 and the large-diameter interval particles 14, the material particles falling into the roller gap 92 have uneven squeezing effect. In order to achieve a good adjusting effect, the roller gap 92 is monitored, and the position and the blanking state of the blanking pipe 7 are dynamically adjusted according to the monitoring result. As shown in fig. 6, when there is a state in which the small diameter interval particles 13 and the large diameter interval particles 14 in the material particle group 15 are unevenly distributed, the P1 layer located at the bottom layer is an uneven layer (including the initial unevenly distributed small diameter interval particles 13 and the initial unevenly distributed large diameter interval particles 14), the P2 layer immediately falling on the P1 layer is formed as an adjustment layer by adjustment of the discharge pipe 7, the large diameter interval particles 14 in the P2 layer are adjusted by the discharge pipe 7, the large diameter interval particles 14 are located at the outermost side, and the end just below the side corresponding to the outermost side becomes the end where the roller gap 92 is the smallest, and when the large diameter interval particles 14 of the P2 layer enter the end where the roller gap 92 is small, the material particle diameter becomes larger, thereby playing a role of adjusting the entire balance of the roller gap 92. And uniformly distributing the particles 13 in the small-diameter interval and the particles 14 in the large-diameter interval in the layer above the P2 layer by adjusting the feeding pipe 7, wherein the P3 layer is a uniform layer, and after the particles 14 in the large-diameter interval in the P2 layer complete the adjustment of the roller gap 92, the balanced roller gap 92 processes the particles of the P3 layer entering the roller press, so that the efficient operation of the roller press 9 can be uniformly maintained.

The invention relates to a plurality of blanking adjusting modes of a blanking pipe 7, aims to realize the functions of uniform throwing, directional adjusting throwing or periodic directional throwing of thrown material particles, and shows 4 adjusting modes, and the embodiment is not limited to only the 4 throwing adjusting modes. The method specifically comprises the following steps:

Referring to fig. 8, in the embodiment, the feeding pipe 71 rotates periodically along the circumferential direction thereof, and the discharging pipe 73 also rotates periodically, but the specific embodiment of the periodic rotation of the feeding pipe 71 is not limited, and only the requirement that the feeding pipe rotates periodically at a fixed rotation frequency or a stepped rotation frequency or a gradual change rotation frequency is met, and the periodic rotation of the discharging pipe 73 at the same time only needs to meet the requirement that the feeding pipe rotates at the same frequency within the rotation range, so that the particles 13 in the small diameter section and the particles 14 in the large diameter section are uniformly dispersed after being thrown above the material particle group 15, and the throwing adjustment method is suitable for the use in the state of a P3 uniform layer.

Referring to fig. 9, the discharging pipe 73 of the illustrated type has a rotation angle of 0 ° < α ≦ 90 °, which is determined according to a horizontal position where the particles 14 of the large diameter interval are thrown to the outermost side of the group of particles 15 of the material, and it can be understood by those skilled in the art that, since the group of particles 15 of the material has a dynamic variable, in order to ensure that the thrown particles of the large diameter interval are located at the outermost side of the group of particles 15 of the material, the discharging pipe 73 is thrown to the outermost side of the group of particles 15 of the material according to a shortest throwing distance that the particles 14 of the large diameter interval can satisfy, and at the same time, the direction of the discharging pipe 73 is directed to a side having an end portion of the smallest roller gap 92, and the discharging pipe 73 and the length direction of the. To adjust the orientation of discharge pipe 73, the orientation of discharge pipe 73 is adjusted by rotating feed pipe 71. The above directional scattering can realize the fixed-point scattering of the particles 14 in the large diameter section, thereby playing a role of adjusting the roller gap 92, and the scattering adjustment mode is suitable for the state use of the P2 adjustment layer. After the fixed-point throwing, the feed pipe 71 periodically rotates along the circumferential direction thereof, and the discharge pipe 73 periodically rotates to cover the P2 adjustment layer again, so that the particles other than the large-diameter interval particles 14 located at the fixed-point position are uniformly dispersed.

Referring to fig. 10, the discharging pipe 73 in the figure has a rotation angle of 0 ° < α ≦ 90 °, the rotation angle is determined according to the horizontal position of the coarse-diameter interval particles 14 thrown to the outermost side of the material particle group 15, and the feeding pipe 71 rotates periodically along the circumferential direction thereof, in practice, the coarse-diameter interval particles 14 are uniformly distributed to the outer ring portion under the action of rotation, and the fine-diameter interval particles 13 are distributed to the inner ring portion, so that the symmetrical distribution in the diameter direction of the horizontal plane of the material particle group 15 is satisfied, and the material particles entering the roller gap 92 are also symmetrically distributed, and the throwing adjustment method is suitable for the P3 uniform layer.

Meanwhile, the motor 2 is electrically connected with a control device, and the control device can obtain the rotation angle or rotation period of the feed pipe 7 driven by the motor 2 according to the deviation of the roller gap 92, so that a part of control effect is realized.

Further, the blanking pipe 7 further comprises an adjusting pipe 72 installed between the feeding pipe 71 and the discharging pipe 73, the adjusting pipe 72 is a flexible pipe, and the rotation of the discharging pipe 73 can be realized by adopting the flexible pipe, so that the disconnection between the discharging pipe 73 and the feeding pipe 71 is avoided in the rotation process. In practice, a bellows is used instead of the adjusting pipe 72, but it is not limited thereto.

It should be noted that this arrangement allows the tapping pipe 73 to be angularly adjusted in its vertical plane by the extension and retraction of the cylinder 82. In practice, the cylinder 82 is connected to a control device, and the control device calculates the angle and period of rotation of the discharge pipe 73 by the cylinder 82 according to the deviation of the roller gap 92 uploaded by the detector 10, so as to achieve another part of the control effect.

After the homogenization and flow stabilization system performs extrusion through the roller press 9, the extruded particles are processed again through subsequent equipment, wherein a part of the coarser particles will again enter the homogenizing and flow stabilizing system through the blanking pipe 7, therefore, in the present embodiment, the blanking pipe 4 is installed on the top of the blanking pipe 7, the blanking pipe 4 comprises a first blanking opening 41 and a second blanking opening 42 which are communicated with a feeding pipe 71, wherein, the new material in the system enters into the blanking pipe 7 through the first blanking port 41, and the part of the circulating material processed by the subsequent equipment enters into the blanking pipe 7 again through the second blanking port 42, generally, in order to uniformly distribute the material particles in the bin body 1, the feeding pipe 73 is generally in a periodic autorotation state, and in the autorotation state, the new material and the circulating material are mixed again and are finally thrown out.

The homogenization steady flow system adopted by the invention adopts a control method of the homogenization steady flow system, and the control method comprises the following steps;

the method comprises the following steps: identifying the distance between the two ends of the adjacent rollers and calculating the roll gap deviation, wherein the roll gap distance at one end is set as S1, the roll gap distance at the other end is set as S2,

the roll gap deviation Delta S is | S1-S2 |;

step two: adjusting the rotation angle of the feeding pipe or/and the rotation angle of the discharging pipe according to the roll gap deviation delta S until the roll gap deviation delta S is within an allowable error range;

step three: detecting the roll gap deviation Delta S again after a preset time period,

if the Delta S is within the allowable error range, the blanking pipe periodically moves along the rotation direction of the feeding pipe;

if the deltaS is beyond the allowable error range, repeating the step two.

Further, the second step includes the following steps:

the method comprises the following steps: adjusting the rotation angle of the feeding pipe or/and the rotation angle of the discharging pipe according to the roll gap deviation Delta S;

step two: comparing S1 and S2, the material particles with larger diameter in the blanking pipe are thrown to the edge above the end with small gap, and then the gap deviation Delta S is within the allowable error range.

Further, when Delta S is more than or equal to 0mm and less than or equal to 8mm, the blanking pipe moves periodically along the rotation direction of the feeding pipe, and the periodic movement comprises feeding pipe autorotation periodic movement and feeding pipe autorotation and discharging pipe rotation periodic movement; when Delta S is more than or equal to 8mm and less than or equal to 30mm, the self-rotation angle of the feeding pipe or/and the rotation angle of the discharging pipe are adjusted, so that the pipe opening part of the discharging pipe points to one side with a small roller gap, and material particles with larger diameters are thrown to the outermost side of the side. It should be noted that the present embodiment is not limited to the range of Δ S in the implementation, and is only applicable to the application of the roll press 9 commonly available in the market and plays an explanatory role.

The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
