Description

Technical Field

[0001] This utility model relates to the field of ternary battery production technology, specifically to a device for recycling waste materials produced in the production of ternary battery materials. Background Technology

[0002] Ternary lithium batteries, also known as ternary polymer lithium batteries, are a type of battery widely used in new energy vehicles, portable electronic devices, and energy storage systems. In low-temperature environments, ternary lithium batteries can still release most of their charge, such as about 70% at -20 degrees Celsius, making them very suitable for use in cold regions. Ternary lithium batteries have a high charge-discharge rate, allowing them to complete the charging or discharging process in a shorter time, thus improving the user experience.

[0003] Currently, in the production process of ternary battery materials, after a period of use, mixed oxides form and gradually accumulate at the outlet of the high-temperature zone of the kiln. Due to the accumulation of oxides, the exhaust vent gradually narrows, affecting the gas emission of the kiln and thus affecting the normal operation of the kiln. To avoid oxide blockage, workers install filters at the outlet pipe to filter and adsorb the oxides. This requires workers to clean the filters regularly, which necessitates temporarily shutting down the kiln, causing production interruptions and reducing production efficiency. Cleaning the filters requires manual operation by workers, which increases their workload and burden. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, an apparatus for recycling waste materials produced in the production of ternary lithium batteries includes an exhaust pipe body 1, with connecting pipes 2 connected to both the left and right sides of the exhaust pipe body 1. A processing box 3 is fixed to the top of the exhaust pipe body 1. Fixing grooves 11 are provided on both the left and right sides of the top of the exhaust pipe body 1. Mounting plates 4 are provided on both the left and right sides inside the processing box 3, and the mounting plates 4 penetrate through the fixing grooves 11 and are slidably connected to the inner wall of the fixing grooves 11. Filter plates 5 are embedded on the surface of the mounting plates 4, and the mounting plates 4 on both sides are staggered. A motor 6 is fixed to the lower front side of the processing box 3. A switching structure 7 is movably connected between the mounting plates 4. A first cylinder 8 is fixed to each of the four sides of the top of the processing box 3, and the bottom end of the output shaft of the first cylinder 8 penetrates into the interior of the processing box 3 and is fixed with a connecting plate 9. A cleaning brush 10 is fixed to one side of the connecting plate 9. A collection groove 12 is provided on both the left and right sides of the top of the exhaust pipe body 1, and a recycling box 13 is slidably connected inside the collection groove 12.

[0023] The switching structure 7 includes a rotating rod 71, a gear 72, and a rack plate 73. The rotating rod 71 is rotatably connected to the lower part of the processing box 3, and the output shaft of the motor 6 passes through the interior of the processing box 3 and is fixedly connected to the front end of the rotating rod 71. The gear 72 is fixed on the front and rear sides of the surface of the rotating rod 71. The rack plate 73 is fixed on the front and rear sides of the opposite side of the surface of the mounting plate 4, and the rack plate 73 is slidably connected to the inner wall of the fixing groove 11. The rack plate 73 and the gear 72 mesh with each other. Limiting grooves 17 are opened on the left and right sides of the front and rear sides of the inner wall of the processing box 3. Limiting blocks 16 are fixed on the upper part of the front and rear sides of the mounting plate 4. One side of the limiting block 16 extends... Extending into the interior of the limiting groove 17 and slidingly connected to the inner wall of the limiting groove 17, when the staff needs to clean the filter plate 5 inside the air outlet body 1, the staff turns on the front motor 6, which causes the output shaft of the motor 6 to drive the rotating rod 71 to rotate, and the gear 72 to rotate. Through the rack plates 73 on both sides, the mounting plates 4 on the left and right sides move. When the mounting plate 4 on the left moves up, the mounting plate 4 on the right moves down, thereby switching the position of the filter plates 5 on both sides. When the mounting plate 4 moves up and down, the limiting block 16 slides inside the limiting groove 17, thereby improving the stability of the mounting plate 4 when it moves up and down.

[0024] A second cylinder 14 is fixed to the rear of both sides of the exhaust pipe body 1. A connecting frame 15 is provided on the rear side of the exhaust pipe body 1, and the output shaft of the second cylinder 14 is fixedly connected to the surface of the connecting frame 15. The rear side of the recycling box 13 is fixedly connected to the surface of the connecting frame 15. When lithium oxide falls into the recycling box 13, the staff can open the second cylinders 14 on both sides, thereby causing the connecting frame 15 to move the recycling box 13 to the rear, so that the staff can directly recycle the lithium oxide inside the recycling box 13.

[0025] An installation box 20 is fixed to the top of the inner wall of the treatment box 3. Several nozzles 21 are installed at the bottom of the installation box 20. A liquid passage pipe is connected to one side of the top of the installation box 20. The liquid passage pipe passes through the treatment box 3 and extends to the outside of the treatment box 3. In order to improve the cleaning effect of the cleaning brush 10 on the lithium oxide on the surface of the filter plate 5, the operator can pour the cleaning agent into the liquid passage pipe. Before the cleaning brush 10 cleans, the nozzles 21 spray out the cleaning agent so that the lithium oxide can be quickly removed from the surface of the filter plate 5 and enter the recovery box 13 below.

[0026] A positioning plate 18 is fixed to the bottom of the mounting plate 4. Positioning grooves 19 are provided on both the left and right sides of the bottom of the inner wall of the air outlet pipe body 1. The positioning plate 18 is slidably connected to the inner wall of the positioning groove 19. When the filter plate 5 on one side is lowered, the positioning plate 18 at the bottom of the mounting plate 4 will be inserted into the corresponding positioning groove 19. The positioning plate 18 and the positioning groove 19 can be used to position the lower half of the mounting plate 4, thereby improving the stability of the filter plate 5 during filtration.

[0027] Working Principle: During the production of ternary battery materials, the generated gas enters the interior of the outlet pipe body 1 through the left connecting pipe 2. When the gas comes into contact with the filter plate 5 on the surface of the mounting plate 4, lithium oxide crystals will form on the surface of the filter plate 5. After a period of use, when the operator needs to clean and recover the lithium oxide on the surface of the left filter plate 5, the operator can turn on the front motor 6, causing the left filter plate 5 to rise and the right filter plate 5 to fall, completing the switching operation between the two filter plates 5. After the switching, the device can continue to filter the gas generated during the production of ternary battery materials. After the switching, the operator can turn on the left filter plate 5 to remove the lithium oxide crystals. The first cylinder 8 on the side is opened, which causes the output shaft of the first cylinder 8 to push the connecting plate 9 down, so that the cleaning brush 10 cleans the surface of the left filter plate 5. The operator controls the movement direction of the output shaft of the first cylinder 8, so that the cleaning brush 10 moves up and down on the surface of the left filter plate 5, scraping the lithium oxide on the surface of the filter plate 5 into the corresponding recycling box 13 below. When the operator needs to recycle the lithium oxide, the operator only needs to open the second cylinders 14 on both sides, so that the connecting frame 15 moves the recycling box 13 backward, and the operator can take out the lithium oxide collected in the recycling box 13 for subsequent recycling work.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
