The homogenizing equipment in the prior art mainly adopts a structure form that a double-planet stirrer is matched with a high-speed dispersion disc.

Specifically, the housing 1 has a first cavity 4 and a second cavity 5 inside, and the first cavity 4 and the second cavity 5 are communicated with each other.

The first rotating body 2 and the second rotating body 3 are relatively independently arranged in the first cavity 4 and the second cavity 5 respectively, and are rotatably connected with the shell 1. The first rotating body 2 and the second rotating body 3 can rotate separately relative to the housing 1, the rotating direction of the first rotating body 2 and the rotating direction of the second rotating body 3 are not affected by each other, and the rotating speed of the first rotating body 2 and the rotating speed of the second rotating body 3 are not affected by each other.
Specifically, the axis of the first rotating body 2 may be aligned with the axis of the second rotating body 3, or the axis of the first rotating body 2 may be disposed at an angle to the axis of the second rotating body 3.
When the first rotating body 2 and the second rotating body 3 rotate, the materials in the first cavity 4 and the second cavity 5 can be disturbed respectively, the mixing of powder and solvent in the materials and the dissolution of the materials are promoted, and the agglomerated materials are subjected to shearing or impact action and are dispersed. And the first and second rotating bodies 2 and 3 can convey the material from either one end of the first or second cavity 4 or 5 to the other end during the rotation.
By controlling the rotation direction of the first rotating body 2, the material entering the first cavity 4 through the first through hole 6 can gradually flow to the second cavity 5, or the material in the first cavity 4 gradually approaches the first through hole 6 and is discharged through the first through hole 6.

In summary, by controlling the rotation directions of the first rotating body 2 and the second rotating body 3, the first rotating body 2 and the second rotating body 3 are matched, so that the material entering the first cavity 4 through the first through hole 6 can be discharged to the second cavity 5 through the second through hole 7, or the material entering the second cavity 5 through the second through hole 7 can be discharged to the first cavity 4 through the first through hole 6, thereby realizing the bidirectional conveying of the material, and further, the dispersing operation of the agglomerated material can be completed in the process of conveying the material.
By the arrangement, the homogenizing equipment provided by the invention is connected with the pulping tank, so that the materials in the pulping tank can be dispersed in the homogenizing equipment once, the probability of disturbance on the agglomerated materials is improved, the dispersing efficiency of the agglomerated materials is improved, the time required by homogenizing and pulping is reduced, and the pulping efficiency is improved.
In particular, two pulping tanks may be used, which are connected to the first through-hole 6 and the second through-hole 7 of the homogenizing device, respectively. The materials are placed in one of the pulping tanks, the first rotating body 2 and the second rotating body 3 are controlled to rotate, the materials are completely conveyed into the other pulping tank, or the materials are conveyed in the two pulping tanks in a reciprocating mode, and the materials are dispersed when passing through the homogenizing equipment.
The first rotor 2 and the second rotor 3 have a shaft portion and a blade group for conveying and disturbing the material. The blade group and the shaft portion may be formed as an integral structure, specifically, the blade group and the shaft portion may be integrally formed, or the blade group may be fixed to the shaft portion after the shaft portion and the blade group are separately processed.
In a specific embodiment, the first rotating body 2 and the second rotating body 3 can be set as turbines or helical blades, so that during the rotation process, not only can materials be conveyed, but also the materials can be stirred, the materials can be uniformly mixed, and the agglomerated materials can be dispersed by using the impact on the agglomerated materials.
The two ends of the shell 1 are provided with supporting parts, the end part of the first rotating body 2 is rotatably connected with the supporting part at one end of the shell 1 through a bearing 13, and a sealing part 14 is arranged at one side of the bearing 13 close to the first cavity 4 to avoid the overflow of materials.
Correspondingly, the end of the second rotor 3 is rotatably connected with the supporting part at the other end of the housing 1 through a bearing 13, and a sealing part 14 is arranged at one side of the bearing 13 close to the second cavity 5 to prevent the materials from overflowing.
In this embodiment the refining apparatus further comprises a first drive member 11 and a second drive member 12.
The output end of the first driving member 11 is in transmission connection with the first rotating body 2 for driving the first rotating body 2 to rotate relative to the housing 1. The output end of the second driving element 12 is in transmission connection with the second rotating body 3 for driving the second rotating body 3 to rotate relative to the housing 1.
In a specific embodiment, the first driving member 11 and the second driving member 12 may be electric motors, a housing of the electric motor is fixedly connected to the housing 1, an output shaft of the electric motor as the first driving member 11 is in transmission connection with an end of the first rotating body 2, and an output shaft of the electric motor as the second driving member 12 is in transmission connection with an end of the second rotating body 3.
In the embodiment of the invention, the side wall of one end of the first cavity 4, which is close to the second cavity 5, is provided with a third through hole 8, the first cavity 4 and the second cavity 5 are both communicated with the third through hole 8, and materials can also enter and exit the first cavity 4 and the second cavity 5 through the third through hole 8.
When the first rotation body 2 is controlled to rotate, the material can be conveyed from the first through hole 6 to the second through hole 7 and/or the third through hole 8, or the material can be conveyed from the second through hole 7 and/or the third through hole 8 to the first through hole 6. The material flow through the second and third through holes 7, 8 depends on the relation between the direction of rotation of the first rotor 2 and the direction of rotation of the second rotor 3 and the speed of rotation of the first rotor 2.
When the second rotating body 3 is controlled to rotate, the materials can be conveyed from the first through hole 6 and/or the third through hole 8 to the second through hole 7, or the materials can be conveyed from the second through hole 7 to the first through hole 6 and/or the third through hole 8. The flow of material through the first through-hole 6 and the third through-hole 8 depends on the relation between the direction of rotation of the first rotor 2 and the direction of rotation of the second rotor 3 and the speed of rotation of the first rotor 2 and the speed of rotation of the second rotor 3.
That is, by controlling the rotation direction and the rotation speed of the first rotating body 2 and the second rotating body 3, respectively, the material flow among the first through hole 6, the second through hole 7 and the third through hole 8 can be controlled, and the homogenizing apparatus can have different operation modes.
For the sake of convenience in explaining the operation mode of the homogenizing apparatus, it is now provided that the direction of rotation of the blade group on the first rotor 2 is the same as the direction of rotation of the blade group on the second rotor 3. When the first rotating body 2 rotates along the first direction, the material enters the first cavity 4 through the first through hole 6 and gradually gets away from the first through hole 6; when the first rotating body 2 rotates along the second direction, the material in the first cavity 4 gradually approaches the first through hole 6 and is discharged through the first through hole 6.

The materials continuously circulate after passing through the first dispersion disc 9 to the second dispersion disc 10, decibels of the materials pass through each second through groove on the second dispersion disc 10, and agglomerated materials can be further dispersed through the disturbance of the second dispersion disc 10 and the impact between the materials and the second dispersion disc 10.

And the first dispersion discs 9 are distributed staggered with respect to the second dispersion discs 10.

In the embodiment of the present invention, the first end of the first cavity 4 is communicated with the first end of the second cavity 5, the cross-sectional dimension of the first cavity 4 gradually decreases along the direction from the first end to the second end, and the cross-sectional dimension of the second cavity 5 gradually decreases along the direction from the first end to the second end. Specifically, the housing 1 may be arranged in a form of splicing two segments of cone portions, a large end of each of the two segments of cone portions is close to a small end of each of the two segments of cone portions, and the first through hole 6 and the second through hole 7 are respectively arranged on sidewalls of the small ends of the two segments of cone portions.

So set up, the material has higher speed when first dispersion dish 9 and second dispersion dish 10, and the impact force between material and the first dispersion dish 9 and the impact force between material and the second dispersion dish 10 are great, are favorable to improving the dispersion effect.
Further, the gap between the shaft portion of the first rotating body 2 and the side wall of the first cavity 4 may be gradually reduced in the direction from the second end to the first end of the first cavity 4, and the gap between the shaft portion of the second rotating body 3 and the side wall of the second cavity 5 may be gradually reduced in the direction from the second end to the first end of the second cavity 5.
