The driving wheel 21 and the driven wheel 22 can drive the mesh chain 23 to move. The chain 23 moves, and the feeding device 1 is located above the mesh chain 23 and at the feeding end. After water and paint leather enter the feeding device 1, the mesh chain 23 can scoop out the paint leather from the feeding device 1. The water filtering device 4 is located below the mesh chain 23 and at the unloading end. The mesh chain 23 can transfer the paint leather from the feeding device 1 to the water filtering device 4. The water filtering device 4 can separate the paint leather from water. The chip discharge structure 5 is located below the water filtering device 4. The driving device 8 is used to drive the driving wheel 21 to rotate.

[0048] The high-pressure water spray equipment sprays the paint off the new energy battery, and then the paint filtering equipment is used to separate the water and the paint. The paint will not be damaged during the separation process. The paint will not be squeezed or scratched throughout the process, and will not break into powder. Finally, a relatively complete and relatively dry paint is obtained, which is conducive to the reuse of the paint.

[0049] Water and paint leather enter the feeding device 1 , the mesh chain 23 can scoop out the paint leather from the feeding device 1 , and the mesh chain 23 transfers the paint leather from the feeding device 1 to the water filtering device 4 , the water filtering device 4 separates the paint leather from the water, and then the paint leather falls from the chip discharge structure 5 .

[0050] Optionally, the water filtering device 4 includes a material receiving plate 41, four water guide plates 42 and four water receiving boxes 43. The material receiving plate 41 is located below the unloading end of the mesh chain 23. The four water guide plates 42 are respectively located around the material receiving plate 41. The water guide plate 42 includes a first guide plate 421 and a second guide plate 422 set at an angle.

[0053] The water filter 4 can separate the water on the surface of the paint leather to reduce the amount of water on the surface of the paint leather. The paint leather falls from the mesh chain 23 to the receiving plate 41, and the paint leather slides from the receiving plate 41 to the first guide plate 421. The paint leather directly falls from the first guide plate 421 to the chip discharge structure 5, and the water on the paint leather flows along the first guide plate 421 and the second guide plate 422 to the water receiving box 43.

[0054] Optionally, the angle between the first guide plate 421 and the second guide plate 422 is 45°. If the angle is too large, water will fall directly from the connection between the first guide plate 421 and the second guide plate 422, and will not flow along the connection between the first guide plate 421 and the second guide plate 422 to the second guide plate 422. The angle between the first guide plate 421 and the second guide plate 422 is 45°, which can make the water on the paint leather flow along the first guide plate 421, through the connection between the first guide plate 421 and the second guide plate 422, and flow to the second guide plate 422.

[0055] In this embodiment, the water guide plate 42 is made of stainless steel.

[0056] Optionally, a plurality of partitions 3 are provided at intervals on the mesh chain 23 along the moving direction of the mesh chain 23. More paint leather can be fished out from the feeding device 1, and the paint leather can be limited in position during the process of the mesh chain 23 transporting the paint leather.

[0057] In this embodiment, the mesh chain 23 is a chain structure with meshes, and the size of the meshes is small enough that the paint will not pass through the meshes. The specific connection relationship between the driving wheel 21, the driven wheel 22 and the mesh chain 23 is a conventional setting. In this embodiment, the feeding end is located at the bottom and the unloading end is located at the top, and the mesh chain 23 can transfer the paint from the bottom to the top.

[0058] Optionally, the patent leather filtering device further comprises a box 9, and the patent leather transmission device, the feeding device 1, and the water filtering device 4 are all located in the box 9. The box 9 can support the patent leather transmission device, the feeding device 1, and the water filtering device 4, and the filtering process of the patent leather is carried out in the box 9, which can prevent the patent leather from being contaminated.

[0059] Optionally, the paint filter device further includes a first air knife 6 and a blower, the blower is connected to the first air knife 6, the blower is fixedly arranged on the box body 9, the first air knife 6 is fixedly arranged in the box body 9, the first air knife 6 is located above the water filter 4, and the first air knife 6 can blow the paint on the mesh chain 23 to the water filter 4. The paint carries water, and the paint will stick to the mesh chain 23 or the partition 3. The blower supplies air to the first air knife 6, and the first air knife 6 can blow air upward and toward the paint transmission device, and the first air knife 6 can blow the paint stuck to the mesh chain 23 and the partition 3.

[0060] Optionally, the patent leather filtering device further comprises a second wind knife 7, the second wind knife 7 is located between two layers of mesh chains 23, the second wind knife 7 is connected to the fan, and the gas blown out by the second wind knife 7 can pass through the mesh holes of the lower mesh chain 23, and blow the patent leather on the lower mesh chain 23 to the water filter 4. It is understandable that the mesh chain 23 is sleeved on the driving wheel 21 and the driven wheel 22, so that a part of the mesh chain 23 is located on the upper layer, and another part of the mesh chain 23 is located on the lower layer. The second wind knife 7 blows air downward, and the blown air passes through the mesh holes of the lower mesh chain 23, blowing off the patent leather stuck to the lower mesh chain 23. The second wind knife 7 can blow off the patent leather that has not been blown off by the first wind knife 6 and has moved to the lower layer with the mesh chain 23, which can increase the blowing rate of the patent leather.

[0061] Optionally, the driving device 8 includes a motor 81, a driving transmission wheel 82, a driven transmission wheel 84 and a transmission chain 83, wherein the motor 81 is fixedly arranged on the housing 9, the driving transmission wheel 82 and the driven transmission wheel 84 are both rotatably arranged on the housing 9, and the two ends of the transmission chain 83 are respectively sleeved on the driving transmission wheel 82 and the driven transmission wheel 84, the driving transmission wheel 82 is transmission-connected to the motor 81, and the driven transmission wheel 84 is fixedly connected to the driving wheel 21.

[0063] The present invention also provides a paint removal method, using the above-mentioned paint skin filtering device, and the specific steps of the paint removal method include:

[0064] High-pressure water spray equipment is used to make the paint peel off, which can make the paint relatively intact during the peeling process and prevent the paint from being scraped and affecting the filtration.

[0065] Feed water and paint leather into the feed device 1.

[0066] The mesh chain 23 fishes out the paint from the feeding device 1 and transmits it to the water filtering device 4. The paint is less damaged.

[0067] The paint leather passes through the material receiving plate 41, the first guide plate 421 and the chip discharge structure 5 in sequence; the water on the paint leather passes through the material receiving plate 41, the first guide plate 421, the second guide plate 422 and the water receiving box 43 in sequence. Taking advantage of the fact that water can flow along the stainless steel plate, the angle between the first guide plate 421 and the second guide plate 422 is appropriate, so that the water can continue to flow along the second guide plate 422 through the bend. The paint leather falls off at the bend, while the water will continue to flow along the second guide plate 422 through the bend. Thus, the paint leather and the water are separated.

[0068] Obviously, the embodiments of the present invention disclosed above are only used to help illustrate the present invention.
