Description

Technical Field

[0001] The present application relates to the field of conductive paste production, and in particular to a single-walled carbon nanotube conductive paste production line. Background Art

[0002] The single-walled carbon nanotube conductive paste is a paste formed by mixing single-walled carbon nanotubes as a conductive agent in a dispersing solvent.

[0003] Due to their extremely small size and highly active surface properties, carbon nanotubes are often difficult to disperse evenly in the slurry. Therefore, the preparation of carbon nanotube conductive slurry is mainly achieved by grinding, stirring and high-energy ball milling. However, this method takes a long time to produce and consumes a lot of energy. In addition, some carbon nanotubes are still unevenly dispersed, resulting in unstable performance of the conductive slurry, which needs to be improved. Summary of the invention

[0004] In order to improve the problem that the current production equipment has poor dispersion effect and easily affects the unstable conductive performance of the conductive paste, the present application provides a single-walled carbon nanotube conductive paste production line.

[0005] The single-walled carbon nanotube conductive slurry production line provided in this application adopts the following technical solution: A single-walled carbon nanotube conductive slurry production line comprises a solvent conveying tank, a feeding tank and a dispersing device, wherein the solvent conveying tank is used to store a solvent, and an output end at the bottom of the solvent conveying tank is connected to the dispersing device, the feeding tank is used to store a powder, and an output end at the bottom of the feeding tank is connected to the dispersing device, the dispersing device comprises a dispersing cylinder and a dispersing assembly, the solvent conveying tank and the feeding tank are both connected to the top of the dispersing cylinder through a hose, a discharge port is provided at the bottom of the dispersing cylinder, the dispersing assembly is located in the dispersing cylinder, and the dispersing assembly can rotate in the dispersing cylinder to disperse the material in the dispersing cylinder.

[0006] By adopting the above technical scheme, when in use, the solvent in the solvent delivery tank and the material in the feeding tank are transported to the dispersion cylinder, and then the dispersion component is started to rotate to shear the material in the dispersion cylinder, and the material that does not meet the specified size is cut into material with a smaller diameter. At the same time, the dispersion component rotates to stir and mix the material and the container in the dispersion cylinder, so that the solvent and the material can be dispersed and mixed at the same time in the dispersion cylinder, so that the solvent and the material are mixed more evenly, meeting the process requirements, that is, the conductive performance of the conductive slurry is not easily affected.

[0007] Optionally, the dispersion assembly includes a mounting frame, a rotating rod, a fixed sleeve and a plurality of blades, the mounting frame is located in the dispersion cylinder and fixed on the top wall of the dispersion cylinder, the rotating rod is rotatably connected to the top wall of the dispersion cylinder, the rotating rod is coaxial with the dispersion cylinder, a rotating disk is coaxially fixed at one end of the rotating rod away from the top wall of the dispersion cylinder, a plurality of blades are fixed on the rotating disk, the fixed sleeve is arranged on the mounting frame and coaxial with the rotating rod, the rotating disk is located in the fixed sleeve, and a plurality of fixing holes are penetrated through the side wall of the fixed sleeve.

[0008] By adopting the above technical solution, the rotating rod is driven to rotate, so that the rotating disk drives the blade to rotate, thereby forming a comprehensive kinetic energy such as the circumferential tangential velocity and the angular velocity in the fixed sleeve, prompting the material to be sucked into the fixed sleeve from the bottom opening of the fixed sleeve, and thrown out from the fixed holes on the peripheral side of the fixed sleeve under the action of centrifugal force. In this process, the material enters the fixed sleeve, and the rotating blade can cut the material to achieve cutting of the material, and the fixed holes divide the material into several portions to achieve dispersion of the material.

[0009] The high-speed rotating dispersion disc generates strong axial flow and radial flow, which shears the material, so that the material can be dispersed and mixed in a very short time to meet the process requirements. The operation is simple and convenient, and the efficiency is improved.

[0010] Optionally, a stirring paddle is coaxially sleeved on the rotating rod, and the stirring paddle is fixed to the rotating rod.

[0011] By adopting the above technical solution, the stirring paddle expands the rotation torque of the rotating rod and the space occupied by the rotating rod in the dispersion tube, that is, when the stirring paddle rotates, the blades of the stirring paddle can beat the solvent and the material, thereby stirring the material and the solvent in the dispersion tube. When the stirring paddle blades rotate, they also generate axial flow and can shear the material, thereby achieving preliminary cutting of the material.

[0012] Optionally, a separation tube is provided in the dispersion tube, the separation tube is coaxial with the dispersion tube, the dispersion assembly is provided in the separation tube, and a containing cavity is formed between the outer side wall of the separation tube and the inner side wall of the dispersion tube.

[0013] By adopting the above technical solution, the partition tube divides the volume of the dispersion cylinder into two parts.

[0014] Optionally, a connecting hole is formed through the side wall of the separation tube, the flow hole is connected with the accommodating cavity, a sieve net is provided in the connecting hole, and the circumferential side wall of the sieve net is fixedly abutted against the inner wall of the connecting hole.

[0015] By adopting the above technical scheme, materials that meet the size requirements of the process can pass through the screening net, that is, materials with smaller diameters can enter the containing chamber through the pores on the screening net, and the solution is not restricted by the screening net and directly flows into the containing chamber, thereby screening the materials in the dispersion cylinder. All materials are screened into two parts, and the materials that meet the requirements are mixed separately with the containing materials in the containing chamber and no longer participate in the shearing of the dispersion component, so that the total amount of materials dispersed by the dispersion component becomes smaller, reducing the workload of dispersion, thereby improving work efficiency.

[0016] Optionally, a sealing member is provided on the inner wall of the partition tube, and the sealing member includes two sealing plates, and the sealing plates can move along the circumference direction of the partition tube. The two sealing plates can abut against each other to seal the connecting hole. A driving assembly is provided in the partition tube, and the driving assembly is connected to the sealing plates for driving the sealing plates to move along the circumference direction of the partition tube.

[0017] By adopting the above technical solution, when the two sealing plates are in contact with each other, the flow hole is in a closed state. When the rotating rod rotates and drives the blade to cut and disperse the material, the driving component is started to drive the two sealing plates away from each other, so that the flow hole is opened, making it convenient for the material that meets the standards to pass through the screening net and enter the containing chamber. Then, the driving component is used to drive the two sealing plates to reset to close the flow hole, so that the material entering the containing chamber is not easy to flow out through the flow hole, thereby ensuring that the material is mixed with the solution separately in the containing chamber.

[0018] Optionally, the driving assembly includes a cam and a driving plate, the cam is coaxially sleeved on the rotating rod, and the cam is fixed to the rotating rod, the driving plate is connected to the mounting frame via a connecting spring, the driving plate is close to the side wall of the rotating rod and abuts against the cam, two driving rods are hinged on the driving plate, the two driving rods correspond to the sealing plate one by one, and one end of the driving rod away from the driving plate is hinged to the sealing plate.

[0019] By adopting the above technical solution, when the rotating rod rotates, the cam is driven to rotate synchronously, and the connecting spring makes the driving plate always abut against the cam. When the tip of the cam rotates to abut against the driving plate, the cam drives the driving plate to move away from the rotating rod, overcoming the elastic force of the connecting spring, so that the two ends of the driving rod gradually approach each other in the radial direction of the dispersion cylinder, and the length of the driving rod is fixed, so that the driving rod rotates, so that one end of the driving rod drives the sealing plate to slide on the inner wall of the separation tube, that is, the two sealing plates move away from each other to open the flow hole for the entry of materials.

[0020] Then, the tip of the cam will separate from the drive plate, and under the elastic force of the connecting spring, the drive plate will move toward the direction close to the rotating rod, so that the drive rod drives the sealing plate to reset and close the flow hole. The setting of the cam makes the drive plate move intermittently, thereby intermittently opening the sealing plate. Due to the rotation of the blade, materials that meet the standard size are continuously produced, and the flow hole is intermittently opened, so that new materials that meet the standards can continue to enter the receiving chamber. When the drive plate approaches the screening net to open the flow hole, it will apply a thrust away from the rotating rod to the solution and the material, making it difficult for the material originally in the receiving chamber to pass through the screening net, that is, the amount of material entering the receiving chamber is greater than the amount of material leaving the receiving chamber.

[0021] Optionally, the top of the dispersion cylinder is fixed on a working frame, a limiting basket is provided on the working frame, the dispersion cylinder is arranged in the limiting basket, and the bottom of the limiting basket is used to block the discharge port.

[0022] By adopting the above technical solution, the limiting basket confines the dispersion tube therein, making it difficult for the dispersion tube to fall over, thereby increasing the stability of the dispersion tube structure.

[0023] Optionally, the limiting basket includes a mounting frame and a limiting frame, the mounting frame is fixed on the working frame, the limiting frame is connected to the mounting frame via a cylinder, the cylinder is used to drive the limiting frame to move up and down, the top of the dispersion cylinder is fixed to the mounting frame, and the bottom wall of the limiting frame can abut against the bottom wall of the dispersion cylinder to block the discharge port.

[0024] By adopting the above technical solution, in the initial state, the cylinder drives the limit frame to move up to block the discharge port. When the material and solvent are mixed and dispersed, the cylinder is started to drive the limit frame to move down, so that the discharge port at the bottom of the dispersion cylinder is fully opened to facilitate discharge.

[0025] Optionally, a flip motor is provided on the work frame, and an output end of the flip motor is connected to the mounting frame for driving the dispersion cylinder to swing.

[0026] By adopting the above technical solution, the turning motor is started to drive the installation frame to rotate, which drives the dispersion cylinder to swing, so that the solvent and material in the dispersion cylinder are shaken, which is convenient for mixing the solvent and the material.

[0027] In summary, the present application includes at least one of the following beneficial effects: 1. Drive the rotating rod to rotate, so that the rotating disk drives the blade to rotate, thereby forming a comprehensive kinetic energy such as the circumferential tangential velocity and angular velocity in the fixed sleeve, prompting the material to be sucked into the fixed sleeve from the bottom opening of the fixed sleeve, and thrown out from the fixed holes on the side of the fixed sleeve under the action of centrifugal force. In this process, the material enters the fixed sleeve, and the rotating blade can cut the material to achieve cutting of the material, and the fixed holes divide the material into several portions to achieve dispersion of the material; 2. Materials that meet the process requirements can pass through the screening net, that is, materials with smaller diameters can enter the containing chamber through the pores on the screening net, while the solution is not restricted by the screening net and flows directly into the containing chamber, thereby screening the materials in the dispersion cylinder. All materials are screened into two parts, and the materials that meet the requirements are mixed separately with the containing materials in the containing chamber and no longer participate in the shearing of the dispersion component, so that the total amount of materials dispersed by the dispersion component becomes smaller, reducing the workload of dispersion, thereby improving work efficiency.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-7This application is described in further detail.

[0031] Embodiment 1, The present application embodiment discloses a single-walled carbon nanotube conductive slurry production line. Figure 1 and Figure 2 The single-walled carbon nanotube conductive slurry production line includes a solvent conveying tank 70, a feeding tank 80 and a dispersing device 30. The dispersing device 30 includes a dispersing cylinder 31 and a dispersing assembly 32. The dispersing cylinder 31 is installed on a working frame 10. The top wall of the dispersing cylinder 31 is fixed to the working frame 10. The bottom of the dispersing cylinder 31 is open with a discharge port. A limiting basket 20 is provided on the working frame 10. The dispersing cylinder 31 is located in the limiting basket 20. The bottom wall of the limiting basket 20 blocks the discharge port, so that the dispersing cylinder 31 is a closed container. The dispersing assembly 32 is located in the dispersing cylinder 31 and can rotate in the dispersing cylinder 31 to disperse the material in the dispersing cylinder 31.

[0032] Reference Figure 1 and Figure 2 The solvent delivery tank 70 and the feeding tank 80 are both connected to the top of the dispersion cylinder 31 through a hose. The solvent is delivered to the solvent delivery tank 70 for storage through a pipeline, and is delivered to the dispersion cylinder 31 by a solvent delivery pump according to process requirements. The feeding tank 80 is used to store powder. When in use, put the powder bag with the bag mouth cut in advance into the feeding box. There is a discharge port at the bottom of the feeding box, which is connected to the vacuum feeder through a pipeline. The vacuum feeder is installed on the top of the conveying system. The material falls directly into the metering bin without dust pollution. Then the powder is transported to the dispersion cylinder 31 through the gravity metering conveying system. When the solvent and the material are both in the dispersion cylinder 31, the dispersion component 32 is started to rotate to shear the material in the dispersion cylinder 31, and the material that does not meet the specified size is cut into material with a smaller diameter. At the same time, the dispersion component 32 rotates to stir and mix the material and the container in the dispersion cylinder 31, so that the solvent and the material can be dispersed and mixed at the same time in the dispersion cylinder 31 to meet the process requirements.

[0033] The dispersing device 30 can also use double tanks for circulating dispersion (not shown in the figure), which can ensure the dispersion without dead angles, and the slurry is circulated at a larger flow rate, which can speed up the circulation speed and the number of dispersions, achieve the purpose of efficient production, and ensure the consistency of dispersed particle size, making the quality more stable. Each process can be run separately. When the system proceeds to the next link, the previous link can prepare and run the next batch. The two batches can achieve seamless docking in the shortest time, with high equipment utilization rate, and maximize system production capacity.

[0034] Reference Figure 2, wherein the limit basket 20 includes a mounting frame 21 and a limit frame 22, the mounting frame 21 and the limit frame 22 are arranged up and down, the top wall of the mounting frame 21 is flush with the top wall of the dispersion tube 31, and is also fixed on the work frame 10, and a cylinder 211 is installed on the mounting frame 21 by bolts, the output end of the cylinder 211 faces downward and is fixed to the limit frame 22, and the cylinder 211 is used to drive the limit frame 22 to move up and down. The specific structure of the mounting frame 21 is a baffle set at the front and back, and the limit frame 22 is a baffle set at the left and right, and the limit frame 22 can be inserted into the mounting frame 21, so that the mounting frame 21 and the limit frame 22 enclose a closed-loop box structure, and the bottom wall of the limit frame 22 can abut against the bottom wall of the dispersion tube 31 to block the discharge port.

[0035] In the initial state, the cylinder 211 drives the limit frame 22 to move up to block the discharge port. When the material and solvent are mixed and dispersed in the dispersion cylinder 31, the cylinder 211 is started to drive the limit frame 22 to move down, so that the discharge port at the bottom of the dispersion cylinder 31 is fully opened for discharge.

[0036] Reference Figure 2 A flip motor 11 is installed on the work frame 10, and the output end of the flip motor 11 is fixed to the top wall of the dispersion cylinder 31. When the flip motor 11 is started, it can drive the dispersion cylinder 31 to swing back and forth, so that the solvent and material in the dispersion cylinder 31 are shaken, which is convenient for mixing the solvent and the material.

[0037] The arrangement of the hose at the top of the dispersion tube 31 enables the dispersion tube 31 to be connected to the solvent tank and the feeding tank 80 without affecting the swing of the dispersion tube 31 .

[0038] Reference Figure 3 and Figure 4 Specifically, the dispersion assembly 32 includes a mounting frame 321, a rotating rod 322, a fixing sleeve 323 and a plurality of blades 3241. A rotating motor is installed on the top wall of the dispersion cylinder 31, and the output end of the rotating motor is coaxially fixed with one end of the rotating rod 322. The rotating rod 322 is located in the dispersion cylinder 31 and arranged along the length direction of the dispersion cylinder 31. The rotating rod 322 is coaxial with the dispersion cylinder 31. A rotating disk 324 is coaxially fixed to one end of the rotating rod 322 away from the top wall of the dispersion cylinder 31, and a plurality of blades 3241 are fixed on the rotating disk 324. The plurality of blades 3241 are radially arranged with the center of the rotating disk 324 as the center of the circle. The blade 3241 can be made of stainless steel or high-strength alloy steel. The shape of the blade 3241 can be a straight blade or a spiral blade. The fixing method of the blade 3241 and the rotating disk 324 can be bolted or welded.

[0039] Reference Figure 3 and Figure 4The mounting frame 321 is located in the dispersion tube 31, and the top of the mounting frame 321 is fixed to the inner top wall of the dispersion tube 31. The fixing sleeve 323 is installed at the bottom of the mounting frame 321 by bolts and is coaxial with the rotating rod 322. The rotating disk 324 is located in the fixing sleeve 323, and a plurality of fixing holes 3231 are opened on the side wall of the fixing sleeve 323.

[0040] The rotating motor is started to drive the rotating rod 322 to rotate, so that the rotating disk 324 drives the blade 3241 to rotate, thereby forming a comprehensive kinetic energy such as the circumferential tangential velocity and the angular velocity in the fixed sleeve 323, so that the material is sucked into the fixed sleeve 323 from the bottom opening of the fixed sleeve 323, and thrown out from the fixed holes 3231 on the peripheral side of the fixed sleeve 323 under the action of centrifugal force. In this process, the material enters the fixed sleeve 323, and the rotating blade 3241 can cut the material to achieve cutting of the material, and the plurality of fixed holes 3231 divide the material into a plurality of portions to achieve dispersion of the material.

[0041] The high-speed rotating dispersion disc generates strong axial flow and radial flow, which shears the material, so that the material can be dispersed and mixed in a very short time to meet the process requirements. The operation is simple and convenient, and the efficiency is improved.

[0042] Reference Figure 3 and Figure 4 , a stirring paddle 3221 is provided on the rotating rod 322, and the stirring paddle 3221 is fixed to the rotating rod 322, and can rotate with the rotating rod 322 in the dispersion cylinder 31, further enhancing the mixing effect of the materials. The addition of the stirring paddle 3221 allows the materials to be subjected to more shearing and mixing effects during the dispersion process, further improving the dispersion effect. Especially when processing high-viscosity materials, the role of the stirring paddle 3221 is more obvious, and can effectively prevent the materials from condensing and precipitating in the dispersion cylinder 31.

[0043] Reference Figure 3 and Figure 5 , a separation tube 40 is provided in the dispersion tube 31, the separation tube 40 is coaxial with the dispersion tube 31, and the dispersion assembly 32 is provided in the separation tube 40. An accommodating chamber 311 is formed between the outer wall of the separation tube 40 and the inner wall of the dispersion tube 31, a connecting hole 41 is provided through the side wall of the separation tube 40, the connecting hole 41 is connected with the accommodating chamber 311, a sieve net 42 is provided in the connecting hole 41, and the circumferential side wall of the sieve net 42 is fixedly abutted against the inner wall of the connecting hole 41. The height of the separation tube 40 is consistent with the height of the dispersion tube 31, and the accommodating chamber 311 is connected with the discharge port.

[0044] When the rotating rod 322 rotates, centrifugal force is generated at the center of the dispersion cylinder 31, so that the material and solution in the dispersion cylinder 31 flow toward the direction of the separation tube 40, and the material that meets the process requirements can pass through the screening net 42, that is, the material with a smaller diameter can enter the receiving chamber 311 through the pores on the screening net 42, and the solution is not restricted by the screening net 42 and flows directly into the receiving chamber 311, so that the material in the dispersion cylinder 31 is screened, and all the materials are screened into two parts. The materials that meet the requirements are mixed with the contained materials separately in the receiving chamber 311, and no longer participate in the shearing of the dispersion component 32, so that the total amount of materials dispersed by the dispersion component 32 is reduced, and the workload of dispersion is reduced, thereby improving work efficiency. At the same time, the structure of the separation tube 40 also makes the flow of materials in the dispersion cylinder 31 smoother, avoiding local overload and blockage.

[0045] Reference Figure 3 and Figure 6 After the material enters the accommodating chamber 311, in order to prevent the material from returning to the dispersion cylinder 31 through the circulation hole, two sealing plates 50 are slidably connected to the inner wall of the partition tube 40. The sealing plates 50 can move along the circumference direction of the partition tube 40. The two sealing plates 50 can abut against each other to block the communication hole 41. A driving assembly 60 is provided in the partition tube 40. The driving assembly 60 is connected to the sealing plate 50 and is used to drive the sealing plate 50 to move along the circumference direction of the partition tube 40.

[0046] Reference Figure 3 and Figure 6 Specifically, the driving assembly 60 includes a cam 61 and a driving plate 62. The cam 61 is coaxially sleeved on the rotating rod 322 and fixed to the rotating rod 322. The driving plate 62 is connected to the mounting frame 321 through a connecting spring 621. The side wall of the driving plate 62 close to the rotating rod 322 abuts against the cam 61. Two driving rods 63 are hinged on the driving plate 62. The two driving rods 63 correspond to the sealing plate 50 one by one. One end of the driving rod 63 away from the driving plate 62 is hinged on the sealing plate 50.

[0047] When the rotating rod 322 rotates, the cam 61 is driven to rotate synchronously, and the connecting spring 621 makes the driving plate 62 always abut against the cam 61. When the tip of the cam 61 rotates to abut against the driving plate 62, the cam 61 drives the driving plate 62 to move away from the rotating rod 322, overcoming the elastic force of the connecting spring 621, so that the two ends of the driving rod 63 gradually approach each other in the radial direction of the dispersion cylinder 31, and the length of the driving rod 63 is fixed, so that the driving rod 63 rotates, so that one end of the driving rod 63 drives the sealing plate 50 to slide on the inner wall of the partition tube 40, that is, the two sealing plates 50 move away from each other to open the flow hole for the material to enter.

[0048] Reference Figure 3 and Figure 6Then, the tip of the cam 61 will separate from the driving plate 62, and under the elastic force of the connecting spring 621, the driving plate 62 will move in the direction close to the rotating rod 322, so that the driving rod 63 drives the sealing plate 50 to reset and close the flow hole. The setting of the cam 61 makes the driving plate 62 move intermittently, thereby intermittently opening the sealing plate 50. Due to the rotation of the blade 3241, materials that meet the standard size are continuously produced, and the flow hole is intermittently opened, so that new materials that meet the standard can continuously enter the accommodating chamber 311. When the driving plate 62 approaches the screening net 42 to open the flow hole, it will apply a thrust away from the rotating rod 322 to the solution and the material, making it difficult for the material originally in the accommodating chamber 311 to pass through the screening net 42, that is, the amount of material entering the accommodating chamber 311 is greater than the amount of material leaving the accommodating chamber 311.

[0049] By providing the sealing plate 50 and the driving assembly 60, the automatic opening and closing of the communicating hole 41 is realized, so that the timing and amount of the material entering the accommodating chamber 311 can be better controlled during the dispersion process. The design of the sealing plate 50 enables the material to be accurately controlled during the dispersion process, avoiding excessive dispersion and waste. The driving assembly 60 has a simple and reliable structure, can effectively drive the sealing plate 50 to move, and further improves the stability and reliability of the system.

[0050] The implementation principle of Example 1 of the present application is as follows: when in use, the solvent in the solvent delivery tank 70 and the material in the feeding tank 80 are transported to the dispersion cylinder 31, and then the dispersion component 32 is started to rotate to shear the material in the dispersion cylinder 31, and the material that does not meet the specified size is cut into material with a smaller diameter. At the same time, the dispersion component 32 rotates to stir and mix the material and the container in the dispersion cylinder 31, so that the solvent and the material can be dispersed and mixed at the same time in the dispersion cylinder 31, so that the solvent and the material are mixed more evenly and the process requirements are met, that is, the conductive performance of the conductive slurry is not easily affected.

[0051] Embodiment 2, The difference between Example 2 of the present application and Example 1 is that, referring to Figure 2 and Figure 7 The sealing member includes a winding roller 51 and a shielding cloth 52. The winding roller 51 is installed on the inner top wall of the dispersion cylinder 31, and the end of the winding roller 51 is rotatably connected to the dispersion cylinder 31. A torsion spring is sleeved on the winding roller 51. One end of the shielding cloth 52 is wound on the winding roller 51 for storage. The shielding plate is tightly attached to the screening mesh 42 and can move vertically along the length direction of the screening mesh 42. When the shielding cloth 52 moves, the elastic force of the torsion spring always pulls the winding roller 51, so that the shielding cloth 52 maintains a tensioned state, thereby achieving the blocking of the pores on the screening mesh 42.

[0052] Reference Figure 7The driving assembly 60 includes an electric push rod 64 and a moving ring 65. The electric push rod 64 is installed on the top wall of the dispersion cylinder 31 by bolts. The moving ring 65 is coaxial with the dispersion cylinder 31 and is located between the separation tube 40 and the dispersion cylinder 31. Specifically, the inner wall of the moving ring 65 abuts against the outer wall of the separation tube 40, and the outer wall of the moving ring 65 abuts against the inner wall of the dispersion cylinder 31. The output end of the electric push rod 64 faces downward and is fixed to the moving ring 65. The electric push rod 64 can drive the moving ring 65 to move up and down.

[0053] Reference Figure 7 The movable ring 65 is fixed to one end of the shielding cloth 52 away from the winding roller 51. When the movable ring 65 moves, it drives the shielding cloth 52 to move, so that the screening net 42 located above the movable ring 65 is always in a closed state, that is, only the screening net 42 below the movable ring 65 is connected to the dispersion cylinder 31 and the separation tube 40.

[0054] When the moving ring 65 moves, it acts as a piston. Specifically, when the moving ring 65 moves upward, the material and solution in the separation tube 40 are drawn through the screening net 42 to between the separation tube 40 and the dispersion cylinder 31, wherein the material that meets the required size can smoothly pass through the pores on the screening net 42, and the material with a larger diameter can forcibly pass through the pores of the screening net 42 under the action of suction, and the edge of the pores on the screening net 42 can also cut the material. When the moving ring 65 moves upward, the suction generated will suck up the material and solution originally deposited between the separation tube 40 and the dispersion cylinder 31, so that the material and solution can be driven by the flip motor 11 to swing the dispersion cylinder 31 left and right to mix, and can also move up and down to mix under the action of the moving ring 65, so as to realize the multi-directional movement of the material and solution and improve the mixing efficiency. When the moving ring 65 moves downward, the material and solution can be squeezed into the separation tube 40, so that the material and solution can pass back and forth on the screening net 42, and the cutting efficiency is improved.

[0055] The implementation principle of Example 2 of the present application is: the material can be driven into between the separation tube 40 and the dispersion tube 31 by the movement of the moving ring 65, so as to realize the screening and mixing of the material. Compared with Example 1, it is simpler and faster, and the material can pass through the screening net 42 back and forth, and the deposited material can continuously roll up and down, thereby improving the efficiency of cutting and mixing.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
