DETAILED DESCRIPTION

[0018] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] like Figure 1-4 As shown, the utility model is a perfluoropolyether raw material recovery device, comprising a base plate 1, a transport box 11 and a crushing box 2 are provided on the base plate 1, a first motor 13 is provided in the transport box 11, a spiral conveying blade 14 is provided at the output end of the first motor 13, and a feeding pipe 15 is provided on the side of the transport box 11. When the perfluoropolyether raw material is put into the transport box 11, by turning on the external power switch of the first motor 13, a cylindrical conveying box is provided in the transport box 11, and the rotation of the first motor 13 can drive the spiral conveying blade 14 to rotate in the transport box 11 to transport the input perfluoropolyether raw material. The perfluoropolyether raw material is transferred from the feeding pipe 15 on the side of the top of the transport box 11 to enter the crushing box 2, which can automatically transport the perfluoropolyether raw material and avoid workers directly feeding the material from the top of the crushing box 2, which is time-consuming and labor-intensive.

[0020] The feeding pipe 15 is connected to the crushing box 2. A shell 22 is provided on the side of the crushing box 2. A second motor 23 is fixedly provided in the shell 22. The output end of the second motor 23 is connected to the crushing roller 26. When the perfluoropolyether raw material is recycled and crushed, the external power switch of the second motor 23 is turned on. A driving gear 24 is sleeved on the output end of the second motor 23. The driving gear 24 is meshed with a driven gear 25 on the side. The driving gear 24 and the driven gear 25 are both connected to the crushing roller 26 on the side. The driving gear 24 fixed on the outside of the second motor 23 drives the driven gear 25 meshed with the side to rotate. The driving gear 24 and the driven gear 25 are rotatably arranged in the shell 22. The crushing rollers 26 at the two locations are rotatably connected in the crushing box 2 through bearings. The rotation of the driving gear 24 and the driven gear 25 can drive the crushing roller 26 to rotate. The arrangement of the driving gear 24 and the driven gear 25 can make the crushing roller 26 in the crushing box 2 rotate synchronously inward, which can fully crush the perfluoropolyether raw material and ensure the crushing effect.

[0021] A first sieve plate 34 is provided in the crushing box 2, and the upper end of the first sieve plate 34 is connected to the slide rod 32. The first sieve plate 34 and the second sieve plate 35 are provided with sieve holes. The perfluoropolyether raw material crushed above falls onto the surface of the first sieve plate 34. The first sieve plate 34 and the second sieve plate 35 are staggered to form filter holes for the material to pass through, so that the perfluoropolyether raw material can be filtered and the perfluoropolyether raw material of the appropriate size can be filtered and collected.

[0022] The sliding rod 32 is slidably connected to the sleeve 31, and a spring 33 is provided in the sleeve 31. The sleeve 31 is fixedly installed at the lower end of the fixed plate 3, and a vibration motor 38 is fixedly provided at the bottom of the second sieve plate 35. By turning on the vibration motor 38 switch, the vibration motor 38 drives the second sieve plate 35 fixedly connected above to shake, and then drives the first sieve plate 34 to shake synchronously. When the first sieve plate 34 starts to shake, the sliding rod 32 slides in the sleeve 31 and squeezes the spring 33, which can ensure the shaking effect of the first sieve plate 34 and the second sieve plate 35, accelerate the filtration speed of the perfluoropolyether raw material in the first sieve plate 34 and the second sieve plate 35, and improve production efficiency.

[0023] The first sieve plate 34 is slidably connected to the second sieve plate 35, and the side of the second sieve plate 35 is connected to a screw 36 extending to the first sieve plate 34. When the filtration size of the perfluoropolyether raw material needs to be adjusted, the screw 36 is rotated, and the external threaded end of the screw 36 is threadedly connected to the side of the first sieve plate 34. The rotation of the screw 36 can drive the first sieve plate 34 to slide inside the second sieve plate 35, so that the filter holes on the surface of the first sieve plate 34 and the filter holes on the surface of the second sieve plate 35 are staggered. When the filter holes are in the same vertical plane, the perfluoropolyether raw material is filtered to the maximum state. After the second sieve plate 35 is slidably set at the lower end of the first sieve plate 34, the caliber size of the perfluoropolyether raw material passing through can be adjusted, which can facilitate workers to adjust the size of the perfluoropolyether raw material particles to be collected.

[0024] In the above solution, a feed port 12 is provided at the lower side of the transport box 11 , and the required perfluoropolyether raw material is added into the feed port 12 .

[0025] In the above solution, the first sieve plate 34 and the second sieve plate 35 are provided with a collection box 16 at the lower end and side thereof, through which the perfluoropolyether raw materials meeting the particle size and the perfluoropolyether raw materials not meeting the particle size can be collected respectively.

[0026] In the above scheme, grooves 21 are opened on both sides of the crushing box 2, and the first screen plate 34 and the second screen plate 35 are movably arranged in the grooves 21. Through the set grooves 21, it is convenient for the vibration motor 38 to drive the first screen plate 34 and the second screen plate 35 to shake, and the screened materials can be guided to the collection box 16 through the grooves 21 at the lower end.

[0027] In the above scheme, four fixing plates 3 are fixed on both sides of the crushing box 2, and the lower ends of the fixing plates 3 are rotatably connected to the first sieve plate 34 through the sliding rod 32. The four fixing plates 3 can ensure the stability of the shaking of the first sieve plate 34 and the second sieve plate 35.

[0028] In the above solution, the screw rod 36 is rotatably connected to the side of the first sieve plate 34 through a bearing, and a handle 37 is provided at the outer end of the screw rod 36, which facilitates the rotation of the screw rod 36.

[0029] Working principle:

[0030] The perfluoropolyether raw material recovery device is specifically designed to feed the perfluoropolyether raw material to be crushed and recovered into the feed port 12 during operation. By turning on the first motor 13, the spiral conveying blade 14 is used to transport the material. When the material enters the crushing box 2, the second motor 23 is turned on. The rotation of the second motor 23 can rotate the two crushing rollers 26 in the crushing box 2 to crush and recover the perfluoropolyether raw material. The crushed perfluoropolyether raw material enters the first sieve plate 34 and the second sieve plate 35. By turning on the vibration motor 38, the screening efficiency of the perfluoropolyether raw material is accelerated. The screened material enters the collection box 16 for centralized collection. The uncrushed perfluoropolyether raw material falls into the side collection box 16 and is re-crushed. When the size of the crushed particles of the perfluoropolyether raw material needs to be adjusted, the handle 37 is turned to rotate the screw 36, driving the second sieve plate 35 and the first sieve plate 34 to be offset, thereby adjusting the cross-sectional area of ​​the holes to suit the required size of the raw material.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
