Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of filtering devices, and particularly relates to a dust filtering workbench for the production of polymer lithium electronic batteries. Background Art
[0002] Polymer lithium electronic batteries, which are a type of lithium battery, will generate impurities such as dust during the production process. The dust may be inhaled by the staff, causing harm to the body, and the dust remaining on the battery will affect the quality and use of the battery. Therefore, during the production process, dust elimination treatment is required.
[0003] The existing technology generally filters dust through a filter screen. After long-term operation, the filter screen is prone to clogging. Moreover, the filtered and collected dust is easily blown up by the air flow to generate secondary dust, resulting in the dust falling on the battery again, and the dust elimination effect is poor. Summary of the Invention
[0004] The purpose of the present invention is to solve the problems in the background art, and a dust filtering workbench for the production of polymer lithium electronic batteries is proposed.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A dust filtering workbench for the production of polymer lithium electronic batteries, including a housing. A battery processing chamber is opened on the inner wall of the top of the housing. A dust collection chamber and a water tank are opened on the inner wall of the housing below the battery processing chamber. The battery processing chamber is communicated with the dust collection chamber. A baffle is welded at the transition between the dust collection chamber and the water tank. A window is opened on the outer wall of the baffle. A circulating air pipe is welded on the outer wall of the water tank. A motor is welded on the outer wall of the housing. A turntable is welded on the outer wall of the main shaft of the motor. The turntable fits with the window. Filter holes are opened on the outer wall of the turntable. A number of equally spaced circumferentially distributed water storage grooves are opened on the outer wall of the turntable. A number of equally spaced circumferentially distributed return grooves are opened on the outer wall of the turntable. The filter holes are communicated with the water storage grooves through the return grooves. A dust reduction mechanism is arranged in the turntable.
[0007] In the above-mentioned dust filtering workbench for the production of polymer lithium electronic batteries, a dust discharge port is opened on the outer wall of the dust collection chamber. A water injection port is opened on the outer wall of the water tank. Clear water is filled in the water tank, and the water level is lower than the window.
[0008] In the above-mentioned dust filtering workbench for the production of polymer lithium electronic batteries, the water tank is communicated with the battery processing chamber through the circulating air pipe. A fan is welded on the main shaft of the motor.
[0009] In the above-mentioned dust filtering workbench for the production of polymer lithium batteries, a brush is rotatably inserted into the inner wall of the dust collection chamber. The brush abuts against the turntable. A toothed ring is welded on the outer wall of the turntable. A gear is welded on the rotating shaft of the brush. The gear meshes with the toothed ring.
[0010] In the above-mentioned dust filtering workbench for the production of polymer lithium batteries, the dust settling mechanism includes a nozzle. A nozzle is arranged on the outer wall of the turntable close to the dust collection chamber. A plug cylinder is opened inside the turntable. The plug cylinder is communicated with the nozzle. A magnet is fixed on the bottom inner wall of the water tank.
[0011] In the above-mentioned dust filtering workbench for the production of polymer lithium batteries, a piston is slidably inserted into the plug cylinder. The piston is attracted by the opposite pole of the magnet. A first spring is welded between the outer wall of the piston and the inner wall of the plug cylinder. An abutting block is welded on the inner wall of the water tank.
[0012] In the above-mentioned dust filtering workbench for the production of polymer lithium batteries, a sliding groove is opened inside the piston. A limiting column is slidably inserted into the sliding groove. The limiting column is adapted to the abutting block. A second spring is welded between the outer wall of the limiting column and the inner wall of the sliding groove. A limiting hole is opened on the outer wall of the plug cylinder. The limiting column is adapted to the limiting hole.
[0013] In the above-mentioned dust filtering workbench for the production of polymer lithium batteries, a water inlet is opened on the outer wall of the plug cylinder.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. By arranging the brush and the fan, the air flow circulates successively through the water tank, the circulating air pipe, the battery processing chamber and the dust collection chamber, so that the dust generated in the battery processing chamber is blown into the dust collection chamber, and the dust is intercepted in the dust collection chamber through the filter holes on the turntable. At the same time, the turntable drives the toothed ring to rotate. Under the meshing action of the toothed ring and the gear, the brush rotates, so as to achieve the effect of cleaning the filter holes and avoid the blockage of the filter holes.
[0016] 2. By arranging the water storage tank, every time the turntable drives the water storage tank to rotate out of the water, the water storage tank will receive a small amount of water. When the turntable drives the water storage tank to rotate to the upper limit position, the water inside the water storage tank will flow along the return groove to the filter holes under the action of gravity, so as to wash the blocked dust in the filter holes and further avoid the blockage of the filter holes. At the same time, when the brush rotates, it can deflect the water in the return groove towards the dust collection chamber, so that when the air flow carries dust into the dust collection chamber, it will be quickly captured by the water droplets deflected by the brush, thus avoiding the generation of secondary dust.
[0017] 3. Through the provided dust reduction mechanism, when the piston drives the limit post to align with the limit hole, under the action of the second spring, the limit post extends out of the sliding groove and inserts into the limit hole, thereby locking the position of the piston. After the turntable drives the plug cylinder into the water, the water in the water tank enters the plug cylinder through the water inlet. When the turntable drives the plug cylinder to rotate towards the abutting block, the abutting block pushes the limit post to compress the second spring, causing the limit post to contract back into the sliding groove again. At this time, under the action of the first spring, the piston quickly resets, so that the water in the plug cylinder is squeezed and sprayed through the nozzle into the dust collection chamber, and then the floating dust in the dust collection chamber is captured by the water mist, and at the same time, the dust accumulated at the bottom of the dust collection chamber is wetted, further avoiding the generation of secondary dust.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a dust filtering workbench for the production of polymer lithium batteries, including a housing 1. A battery processing chamber 11 is provided on the inner wall of the top of the housing 1. A dust collection chamber 12 and a water tank 13 are provided on the inner wall of the housing 1 below the battery processing chamber 11. The battery processing chamber 11 is communicated with the dust collection chamber 12. A baffle 14 is welded at the transition between the dust collection chamber 12 and the water tank 13. A window 141 is provided on the outer wall of the baffle 14. A circulating air pipe 15 is welded on the outer wall of the water tank 13. A motor 2 is welded on the outer wall of the housing 1. A turntable 21 is welded on the outer wall of the main shaft of the motor 2. The turntable 21 is in contact with the window 141. Filter holes 211 are provided on the outer wall of the turntable 21. A number of equally spaced circumferentially distributed water storage grooves 22 are provided on the outer wall of the turntable 21. A number of equally spaced circumferentially distributed return grooves 23 are provided on the outer wall of the turntable 21. The filter holes 211 are communicated with the water storage grooves 22 through the return grooves 23. A dust reduction mechanism is provided inside the turntable 21. A dust discharge port 121 is provided on the outer wall of the dust collection chamber 12. A water injection port 131 is provided on the outer wall of the water tank 13. Clear water is filled in the water tank 13, and the water level is lower than the window 141. The water tank 13 is communicated with the battery processing chamber 11 through the circulating air pipe 15. A fan 25 is welded on the main shaft of the motor 2. A brush 3 is rotatably inserted into the inner wall of the dust collection chamber 12. The brush 3 abuts against the turntable 21. A gear ring 24 is welded on the outer wall of the turntable 21. A gear 31 is welded on the rotating shaft of the brush 3. The gear 31 meshes with the gear ring 24.
[0030] During operation, clean water with a water level lower than the window 141 is injected into the water tank 13. The motor 2 is started, and the motor 2 drives the fan 25 to rotate, so that the air flow circulates successively through the water tank 13, the circulation air pipe 15, the battery processing chamber 11 and the dust collection chamber 12. As a result, the dust generated in the battery processing chamber 11 is blown into the dust collection chamber 12, and the dust is intercepted in the dust collection chamber 12 through the filter holes 211 on the turntable 21. At the same time, the turntable 21 drives the gear ring 24 to rotate. Under the meshing action of the gear ring 24 and the gear 31, the brush 3 rotates, so as to achieve the effect of cleaning the filter holes 211 and avoid the blockage of the filter holes 211.
[0031] Moreover, whenever the turntable 21 drives the water storage tank 22 to rotate out of the water, the water storage tank 22 will receive a small amount of water. When the turntable 21 drives the water storage tank 22 to rotate to the upper limit position, the water inside the water storage tank 22 will flow along the return groove 23 to the filter holes 211 under the action of gravity, so as to wash the blocked dust in the filter holes 211 and further avoid the blockage of the filter holes 211. At the same time, when the brush 3 rotates, it can deflect the water in the return groove 23 towards the dust collection chamber 12, so that when the air flow carries dust into the dust collection chamber 12, it will be quickly captured by the water droplets deflected by the brush 3, thus avoiding the generation of secondary dust.
[0032] Specifically, the dust reduction mechanism includes a nozzle 26. The nozzle 26 is arranged on the outer wall of one side of the turntable 21 close to the dust collection chamber 12. A plug cylinder 27 is opened inside the turntable 21. The plug cylinder 27 is communicated with the nozzle 26. A magnet 133 is fixed on the bottom inner wall of the water tank 13. A piston 4 is slidably inserted into the plug cylinder 27. The piston 4 is attracted by the opposite pole of the magnet 133. A first spring 41 is welded between the outer wall of the piston 4 and the inner wall of the plug cylinder 27. An abutting block 132 is welded on the inner wall of the water tank 13. A chute 42 is opened inside the piston 4. A limiting column 5 is slidably inserted into the chute 42. The limiting column 5 is adapted to the abutting block 132. A second spring 51 is welded between the outer wall of the limiting column 5 and the inner wall of the chute 42. A limiting hole 272 is opened on the outer wall of the plug cylinder 27. The limiting column 5 is adapted to the limiting hole 272. A water inlet 271 is opened on the outer wall of the plug cylinder 27.
[0033] In the initial state, under the action of the first spring 41, the piston 4 is located at one end of the plug cylinder 27 close to the nozzle 26. The limiting column 5 contracts in the chute 42, and the second spring 51 is compressed.
[0034] During operation, when the turntable 21 drives the plug cylinder 27 to rotate towards the magnet 133, under the action of magnetic force, the piston 4 compresses the first spring 41 and then slides towards the end away from the nozzle 26. When the piston 4 drives the limit post 5 to align with the limit hole 272, under the action of the second spring 51, the limit post 5 extends from the chute 42 and inserts into the limit hole 272, thus locking the position of the piston 4. As the turntable 21 drives the plug cylinder 27 to rotate into the water, the water in the water tank 13 enters the plug cylinder 27 through the water inlet 271. When the turntable 21 drives the plug cylinder 27 to rotate towards the abutting block 132, the abutting block 132 pushes the limit post 5 to compress the second spring 51, causing the limit post 5 to contract back into the chute 42 again. At this time, under the action of the first spring 41, the piston 4 quickly resets, so that the water in the plug cylinder 27 is squeezed and sprayed through the nozzle 26 into the dust collection chamber 12, thereby capturing the floating dust in the dust collection chamber 12 with water mist and wetting the dust accumulated at the bottom of the dust collection chamber 12, further avoiding the generation of secondary dust.
[0035] Working principle and usage process of the present invention: During operation, clean water with a water level lower than the window 141 is injected into the water tank 13. The motor 2 is started, and the motor 2 drives the fan 25 to rotate, causing the air flow to circulate successively through the water tank 13, the circulation air pipe 15, the battery processing chamber 11, and the dust collection chamber 12. As a result, the dust generated in the battery processing chamber 11 is blown into the dust collection chamber 12, and the dust is intercepted in the dust collection chamber 12 through the filter holes 211 on the turntable 21. At the same time, the turntable 21 drives the gear ring 24 to rotate. Under the meshing action of the gear ring 24 and the gear 31, the brush 3 rotates, thereby achieving the effect of cleaning the filter holes 211 and preventing the filter holes 211 from being blocked. Moreover, whenever the turntable 21 drives the water storage tank 22 to rotate out of the water, the water storage tank 22 will receive a small amount of water. When the turntable 21 drives the water storage tank 22 to rotate to the upper limit position, the water inside the water storage tank 22 will flow along the return groove 23 to the filter holes 211 under the action of gravity, thereby flushing the blocked dust in the filter holes 211 and further preventing the filter holes 211 from being blocked. At the same time, when the brush 3 rotates, it can deflect the water in the return groove 23 towards the dust collection chamber 12, so that when the air flow carries dust into the dust collection chamber 12, it will be quickly captured by the water droplets deflected by the brush 3, thereby avoiding the generation of secondary dust. At the same time, through the set dust reduction mechanism, when the turntable 21 drives the plug cylinder 27 to rotate towards the magnet 133, under the action of magnetic force, the piston 4 compresses the first spring 41 and slides towards the end away from the nozzle 26. When the piston 4 drives the limit post 5 to align with the limit hole 272, under the action of the second spring 51, the limit post 5 extends out of the chute 42 and inserts into the limit hole 272, thereby locking the position of the piston 4. As the turntable 21 drives the plug cylinder 27 to rotate into the water, the water in the water tank 13 enters the plug cylinder 27 through the water inlet 271. When the turntable 21 drives the plug cylinder 27 to rotate towards the abutting block 132, the abutting block 132 pushes the limit post 5 to compress the second spring 51, causing the limit post 5 to contract back into the chute 42 again. At this time, under the action of the first spring 41, the piston 4 quickly resets, so that the water in the plug cylinder 27 is squeezed and sprayed into the dust collection chamber 12 through the nozzle 26, thereby capturing the floating dust in the dust collection chamber 12 through the water mist and wetting the dust accumulated at the bottom of the dust collection chamber 12, further avoiding the generation of secondary dust.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
