[0002] With the development of society, people pay more and more attention to environmental protection, and plastic films (such as PV films, PE films) and lithium batteries generated in production and life will be recycled; at present, the dehydrator used for recycling plastic films (the dehydrator is used to dehydrate the crushed plastic films) and the diaphragm black powder separation device used for recycling lithium batteries (the diaphragm black powder separation device is used to separate the diaphragm and black powder in the lithium battery material after crushing and low-temperature drying) are not universal. In this way, environmental sanitation enterprises that need to recycle plastic films and lithium batteries need to purchase a dehydrator and a diaphragm black powder separation device at the same time, which increases the equipment cost of environmental sanitation enterprises.
[0003] In view of the existence of the above problems, it is necessary to study a dual-purpose dehydration and separation device, which can not only dehydrate plastic films, but also separate the diaphragm and black powder of lithium batteries, which is beneficial to reducing the equipment cost of environmental sanitation enterprises. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a dual-purpose dehydration and separation device, which can not only dehydrate plastic films, but also separate the diaphragm and black powder of lithium batteries, which is beneficial to reducing the equipment cost of environmental sanitation enterprises.
[0005] To achieve the above purpose, the solution of the utility model is:
[0006] A dual-purpose dehydration and separation device includes a chassis, a screen assembly, and a driving device; the screen assembly is rotatably installed in the chassis. The screen assembly includes a main shaft rotatably installed in the chassis, a mounting bracket fitted on the main shaft, and a screen fitted on the mounting bracket. The screen is cylindrical and is provided with a number of screen holes. The screen is sleeved on the main shaft and there is a screening chamber with open ends at both ends between the screen and the main shaft. A plurality of feeding plates inclined to the circumferential direction of the screen are fitted inside the screen; the chassis is provided with a feeding hopper and a discharging hopper. The discharging end of the feeding hopper and the feeding end of the discharging hopper are respectively connected to the feeding end and the discharging end of the screening chamber. The discharging end of the feeding hopper is higher than the feeding end of the discharging hopper. A discharge port is provided at the bottom of the chassis; the driving device is in transmission cooperation with the main shaft of the screen assembly.
[0007] The chassis includes a box body with an open top and a box cover fitted on the top of the box body.
[0008] A sealing ring is clamped between the box body and the box cover of the chassis.
[0009] Both ends of the main shaft of the screen assembly are rotatably connected to the chassis through bearings.
[0010] The driving device comprises a driving motor, a main pulley, a slave pulley and a transmission belt, wherein the main pulley is coaxially connected to the driving motor, the slave pulley is coaxially connected to the main shaft of the screen assembly, and the transmission belt is connected to the main pulley and the slave pulley.
[0011] The driving motor, the main pulley, the slave pulley and the transmission belt of the driving device are all located outside the chassis, and the chassis is connected to a belt cover which covers the slave pulley and the transmission belt.
[0012] The discharge end of the feed hopper extends into the screening chamber of the screen assembly and is higher than the main axis of the screen assembly.
[0013] The feed end of the discharge hopper is connected with the discharge end of the screening chamber through a discharge plate. The discharge plate is tilted, and the two ends of the discharge plate extend into the feed end of the discharge hopper and the discharge end of the screening chamber respectively.
[0014] The side wall of the chassis is provided with an inspection opening, and the inspection opening is matched with an inspection door.

[0016] After adopting the above scheme, the dehydration and separation dual-purpose equipment of the utility model can not only dehydrate the plastic film, but also separate the diaphragm and black powder of the lithium battery, which is beneficial to reducing the equipment cost of the sanitation enterprise.
[0017] When the dehydration and separation dual-purpose device of the utility model is used to dehydrate plastic film, the broken plastic film is put into the feed end of the screening chamber of the screen assembly from the feed hopper, and the driving device first drives the main shaft of the screen assembly to rotate at a low dehydration speed for a preset time. During this process, the centrifugal force on the plastic film is small due to the low main shaft speed. In this way, the plastic film will be moved by the material shifting plate and will move along the axial direction of the screen toward the discharge end of the screening chamber; thereafter, the driving device drives the main shaft of the screen assembly to rotate at a high dehydration speed. At this time, the plastic film will cling to the inner wall of the screen under the action of centrifugal force, and the water attached to the surface of the plastic film will be thrown away from the plastic film through the mesh holes of the screen due to the centrifugal force, thereby achieving the dehydration and drying effect, and the thrown away water is discharged from the discharge port outside the chassis; after the driving device drives the main shaft of the screen assembly to rotate at a high dehydration speed for a preset drying time, the driving device drives the main shaft of the screen assembly to rotate at a low dehydration speed for a preset time, so that the dehydrated plastic film is moved by the material shifting plate and moves along the axial direction of the screen into the discharge hopper for discharge. As can be seen from the above, the driving device drives the main shaft of the screen assembly to cyclically switch between high dehydration speed and low dehydration speed, so that the continuous feeding, discharging and drying of the plastic film can be realized, and continuous drying treatment can be achieved.
[0018] When a dehydration and separation dual-purpose device of the present utility model is used to separate the diaphragm and black powder of a lithium battery, the crushed and dried lithium battery materials are put into the feeding end of the screening chamber of the screen assembly from the feeding hopper. The driving device first drives the main shaft of the screen assembly to rotate at a separation speed. During this process, the lithium battery materials will first move upward along the screen and then fall under the drive of the material pushing plate, so that the lithium battery materials are impacted and the diaphragm and black powder of the lithium battery materials are separated. Among them, the black powder will enter the discharge port of the chassis through the screen holes of the screen and be discharged from the discharge port, while the diaphragm cannot pass through the screen holes of the screen and will be pushed by the material pushing plate and move towards the discharge end of the screening chamber and enter the discharge hopper for discharging.

[0036] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.
[0037] As Figures 1 to 6 shown, the present invention discloses a dual-purpose dehydration and separation device, which includes a chassis 1, a screen assembly 2, and a driving device 3; wherein, the screen assembly 2 is rotatably installed in the chassis 1, and the screen assembly 2 includes a main shaft 21 rotatably installed in the chassis 1, a mounting bracket 22 fitted on the main shaft 21, and a screen 23 fitted on the mounting bracket 22. The screen 23 is cylindrical and is provided with a plurality of screen holes. The screen 23 is sleeved on the main shaft 21 and there is a screening chamber 20 with open ends at both ends between the screen 23 and the main shaft 21. A plurality of material guiding plates 24 inclined to the circumferential direction of the screen 23 are fitted inside the screen 23; the chassis 1 is provided with a feed hopper 4 and a discharge hopper 5. The discharge end of the feed hopper 4 and the feed end of the discharge hopper 5 are respectively connected to the feed end and the discharge end of the screening chamber 20. The discharge end of the feed hopper 4 is higher than the feed end of the discharge hopper 5. A discharge port 111 is provided at the bottom of the chassis 1; the driving device 3 is in transmission cooperation with the main shaft 21 of the screen assembly 2.
[0038] The dual-purpose dehydration and separation device of the present invention can not only dehydrate plastic films, but also separate the diaphragms and black powders of lithium batteries, which is beneficial to reducing the equipment costs of environmental sanitation enterprises.
[0039] When the dehydration and separation dual-purpose device of the utility model is used to dehydrate plastic film, the broken plastic film is put into the feed end of the screening chamber 20 of the screen assembly 2 from the feed hopper 4, and the driving device 3 first drives the main shaft 21 of the screen assembly 2 to rotate at a low dehydration speed (the low dehydration speed can be 20-60RPM) for a preset time (can be 10-30s). During this process, the centrifugal force on the plastic film is small due to the low speed of the main shaft 21. In this way, the plastic film will be moved by the material shifting plate 24 and will move along the axial direction of the screen 23 toward the discharge end of the screening chamber 20; thereafter, the driving device 3 drives the main shaft 21 of the screen assembly 2 to rotate at a high dehydration speed (high dehydration speed). The water speed can be 500-800RPM) and the plastic film will be closely attached to the inner wall of the screen 23 under the action of centrifugal force, and the water attached to the surface of the plastic film will be thrown away from the plastic film through the sieve holes of the screen 23 due to the centrifugal force, thereby achieving the dehydration and drying effect, and the thrown away water is discharged from the outside of the chassis 1 from the discharge port 111; after the driving device 3 drives the main shaft 21 of the screen assembly 2 to rotate at a high dehydration speed for a preset drying time (which can be 1-2 minutes), the driving device 3 drives the main shaft 21 of the screen assembly 2 to rotate at a low dehydration speed for a preset time, so that the dehydrated plastic film is moved by the material shifting plate 24 and moves along the axial direction of the screen 23 into the discharge hopper 5, thereby discharging. As can be seen from the above, the driving device 3 drives the main shaft 21 of the screen assembly 2 to switch cyclically between high dehydration speed and low dehydration speed, so that the continuous feeding, discharging and drying of the plastic film can be realized, and continuous drying treatment can be realized.
[0040] When a dehydration and separation dual-purpose device of the utility model is used to separate the diaphragm and black powder of a lithium battery, the crushed and dried lithium battery material is put into the feed end of the screening chamber 20 of the screen assembly 2 from the feed hopper 4, and the driving device 3 first drives the main shaft 21 of the screen assembly 2 to rotate at a separation speed (the separation speed can be 10-50RPM). During this process, the lithium battery material will first move up along the screen 23 and then fall down under the drive of the material shifting plate 24, so that the lithium battery material is impacted and the diaphragm and black powder of the lithium battery material are separated, wherein the black powder will pass through the sieve holes of the screen 23 into the discharge port 111 of the chassis 1 and be discharged from the discharge port 111, while the diaphragm cannot pass through the sieve holes of the screen 23, and the diaphragm will be shifted by the material shifting plate 24 to move to the discharge end of the screening chamber 20 and enter the discharge hopper 5 for discharge.
[0041] In an embodiment of the present utility model, the chassis 1 includes a box body 11 with an open top and a box cover 12 detachably fitted to the top of the box body 11, so that the chassis 1 can be disassembled to replace the screen assembly 2. Among them, there are two specifications for the screen assembly 2 of the present utility model. The aperture of the screen holes of the screen 23 of the first specification of the screen assembly 2 is 4 - 6 mm, and the aperture of the screen holes of the screen 23 of the second specification of the screen assembly 2 is 2 - 3 mm. The first specification of the screen assembly 2 is suitable for use in dehydrating plastic films, and the second specification of the screen assembly 2 is suitable for use in dehydrating plastic films and separating the separator and black powder of lithium batteries.
[0042] In an embodiment of the present utility model, a sealing ring is clamped between the box body 11 and the box cover 12 of the chassis 1, so as to prevent water or black powder from leaking between the box body 11 and the box cover 12.
[0043] In an embodiment of the present utility model, a maintenance opening 112 is provided on the side wall of the chassis 1, and the maintenance opening 112 is fitted with a maintenance door 113, so as to facilitate the maintenance of the screen assembly 2. The maintenance opening 112 and the discharge port 111 of the chassis 1 can be on the box body 11 of the chassis 1.
[0044] In an embodiment of the present utility model, a spray pipe 6 for introducing fluid is installed in the chassis 1. The spray pipe 6 is located below the screen assembly 2, and a plurality of spray holes are provided on the spray pipe 6. When a dehydration and separation dual-purpose device of the present utility model is used to dehydrate a plastic film, after the dehydration is completed, clean water can be introduced into the spray pipe 6, and the spray holes of the spray pipe 6 spray water into the chassis 1 to clean the chassis 1 and the screen assembly 2. When a dehydration and separation dual-purpose device of the present utility model is used to separate the separator and black powder of a lithium battery, compressed air can be introduced into the spray pipe 6, and the spray holes of the spray pipe 6 intermittently spray air on the screen 23 to prevent the black powder from blocking the screen holes of the screen 23.
[0045] In an embodiment of the present utility model, both ends of the main shaft 21 of the screen assembly 2 are rotatably connected to the chassis 1 through bearings 7, so that the screen assembly 2 can rotate smoothly.
[0046] In an embodiment of the present utility model, the mounting bracket 22 of the screen assembly 2 may include two hubs 221 and a plurality of screen mounting plates 222. The two hubs 221 are respectively fixedly installed at both ends of the main shaft 21. Both ends of each screen mounting plate 222 are respectively connected to the two hubs 221, and the screen 23 is connected to each screen mounting plate 222. The screen 23 may include at least two arc-shaped screen pieces 231, and the arc-shaped screen pieces 231 are butted to form the screen 23. Among them, the hub 221 can be fixedly installed on the main shaft 21 through a key bar. The screen mounting plate 222 can be locked with the hub 221 through a connecting bolt. The screen piece 231 can be locked with the screen mounting plate 222 through a locking bolt 25. The adjacent locking bolts 25 can be connected by a stainless steel wire 26 to prevent the locking bolts 25 from loosening.
[0047] In an embodiment of the present utility model, the material pushing plates 24 of the screen assembly 2 can be arranged in multiple rows, and each row of material pushing plates 24 is symmetrically distributed about the main shaft 21.
[0048] In an embodiment of the present utility model, the driving device 3 includes a driving motor 31, a main belt pulley 32, a driven belt pulley 33 and a transmission belt 34. The main belt pulley 32 is coaxially connected to the driving motor 31. The driven belt pulley 33 is coaxially connected to the main shaft 21 of the screen assembly 2. The transmission belt 34 is connected to the main belt pulley 32 and the driven belt pulley 33. In this way, the driving motor 31 can drive the main shaft 21 of the screen assembly 2 to rotate through the main belt pulley 32, the driven belt pulley 33 and the transmission belt 34, and the rotation speed of the main shaft 2 can be easily controlled through the driving motor 31. Among them, the driving motor 31, the main belt pulley 32, the driven belt pulley 33 and the transmission belt 34 of the driving device 3 are all located outside the chassis 1. The chassis 1 is connected with a belt cover 8 covering the main belt pulley 32, the driven belt pulley 33 and the transmission belt 34 to protect the safety of personnel; the driving motor 31 and the box body 11 of the chassis 1 can be cooperated on the rack A together.
[0049] In an embodiment of the present utility model, the discharge end of the feed hopper 4 extends into the screening chamber 20 of the screen assembly 2 and is higher than the main shaft 21 of the screen assembly 2. In this way, the impact force of the material (broken plastic film and broken and dried lithium battery material) when entering the screening chamber 20 and contacting the screen 23 can be increased, making it easier for the material to disperse.
[0050] In an embodiment of the present utility model, the feeding end of the discharge hopper 5 is connected to the discharge end of the screening chamber 20 through a discharge plate 9. The discharge plate 9 is inclined, and both ends of the discharge plate 9 extend into the feeding end of the discharge hopper 5 and the discharge end of the screening chamber 20 respectively. In this way, when the material (the broken plastic film and the broken and dried lithium battery material) is to be output from the screening chamber 20 of the screen assembly 2, the deflector 24 near the discharge end of the screening chamber 20 drives the material to rise. After the material rises to a certain height, the material will slide onto the discharge plate 9 under the action of its own gravity, and then the material slides into the discharge hopper 5 along the discharge plate 9.
[0051] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the relevant technical field shall be regarded as not departing from the patent scope of the present utility model.
