[0073] Furthermore, the rolling part 312 in the present device is a ball or steel ball that is common and easy to purchase on the market. The ball or steel ball here is a conventional setting known to those skilled in the art and will not be described in detail.

[0074] like Figure 1 , Figure 4As shown, the backwashing component 32 includes a connecting rod 321, at least one flushing pipe 322, a water tank 323 and at least one boosting pump 324. The two ends of the connecting rod 321 are respectively connected to the two sliding blocks 311. The flushing pipe 322 is detachably connected to the connecting rod 321 and has a liquid inlet end and a liquid outlet end. The liquid outlet end of the flushing pipe 322 is arranged relative to the bottom inner wall of the discharge battery 1. The water tank 323 is connected to the discharge battery 1. The liquid inlet end of the boosting pump 324 is built into the water tank 323, and the liquid outlet end is communicated with the liquid inlet end of the flushing pipe 322.

[0075] Furthermore, the connecting rod 321 is used to connect the two sliding blocks 311 to form a whole. The flushing pipe 322 is connected to the connecting rod 321 and is used to move with the sliding of the sliding block 311 and the connecting rod 321. Under the pressurized action of the booster pump 324, high-pressure water is sprayed out from the flushing pipe 322, which can clean the inner wall of the discharge cell 1 and prevent the precipitated crystallized salt from adhering to the inner wall of the discharge cell 1.

[0076] Specifically, in the device, the flushing pipe 322 is arranged relative to the bottom inner wall of the discharge battery 1 , and can flush the bottom inner wall of the discharge battery 1 when following the movement of the sliding block 311 .

[0077] As an implementation method, Figure 1 , Figure 4 As shown, there are multiple flushing pipes 322 in the backwashing part 32, and the multiple flushing pipes 322 are evenly distributed along the length direction of the connecting rod 321 and are all connected to the connecting rod 321, and the liquid inlet ends of the multiple flushing pipes 322 are all connected to the liquid outlet ends of the booster pump 324.

[0082] Furthermore, the bionic drive unit in the present device is a waterproof motor directly built into the discharge battery 1.

The filter 43 is built into the sewage pool 41, and the water pump 44 is arranged on the drainage pipe.

[0084] The crystallized salt flushed by the high-pressure water jetted from the flushing pipe 322 in the discharge cell 1 is discharged from both sides of the discharge cell 1 by the water pump 44 and collected and filtered to prevent the crystallized salt from adhering to the inner wall of the discharge cell 1 for a second time.

[0085] Furthermore, in the present device, the sodium chloride solution filtered by the filter element 43 can be transported to the water tank 323 for flushing the flushing pipe 322, which will not be described in detail here.

[0086] like Figure 2 As shown, the device also includes an exhaust gas treatment component 5, which includes an exhaust gas hood 51, a plurality of sealing curtains 52, a negative pressure vacuum pump 53 and an exhaust gas filter 54.

[0088] Furthermore, the exhaust hood 51, multiple sealing curtains 52, negative pressure vacuum pump 53 and exhaust filter 54 are all common and easy-to-purchase equipment on the market. They are conventional settings well known to those skilled in the art and will not be described in detail.

[0089] The specific working process of the present invention is to partially extend the conveying component 2 into the discharge cell 1, send the battery monomer or battery module obtained after the battery pack is disassembled into the discharge cell 1, and then send the battery monomer or battery module obtained after the battery pack is disassembled out of the discharge cell 1 after discharge, so as to complete the transportation and discharge of the battery monomer or battery module obtained after the battery pack is disassembled. At the same time, a backwashing member 32 is arranged inside the discharge cell 1, and the backwashing member 32 is connected to the inner wall of the discharge cell 1 through a sliding member 31. Driven by the driving member 33, the backwashing member 32 can slide back and forth relative to the inner wall of the discharge cell 1 together with the sliding member 31, so as to repeatedly wash the crystallized salt in the discharge cell 1. Compared with the prior art, by setting up the conveying component 2, the battery cells or battery modules obtained after disassembling the battery pack can be automatically sent into the discharge battery 1 for discharge, and the battery cells or battery modules obtained after disassembling the battery pack can be automatically sent out after the discharge is completed. The crystallized salt precipitated on the inner wall of the discharge battery 1 is washed by the backwashing component 32, and the driving component 33 is used to drive the sliding component 31 and the backwashing component 32 to slide reciprocatingly relative to the discharge battery 1 to improve the washing effect.

[0090] When in use, the user first places the battery cells or battery modules obtained after disassembling the battery pack to be discharged on the first horizontal conveyor belt 211, and then the battery cells or battery modules obtained after disassembling the battery pack to be discharged pass through the first horizontal conveyor belt 211, the first inclined conveyor belt 214, the second horizontal conveyor belt 212, the second inclined conveyor belt 215 and the third conveyor belt in turn for discharge treatment. At the same time, after a period of time, the booster pump 324 is started, so that high-pressure liquid is continuously ejected from the flushing pipe 322 to flush the crystallized salt. Finally, under the drive of the waterproof drive unit 332, the screw 331 rotates forward or reversely around its axis, driving the sliding block 311, the connecting rod 321 and the multiple flushing pipes 322 to slide back and forth along the guide of the slide groove, thereby improving the flushing effect.

[0091] Furthermore, during the continuous flushing of the flushing pipe 322, the water pump 44 also works synchronously to extract the crystallized salt and liquid washed off the bottom of the discharge battery 1 and filter them, while the negative pressure vacuum pump 53 works to collect and filter the exhaust gas generated during the discharge process.

[0092] The device, through the above structure, can solve the technical problem in the prior art that the battery cells or battery modules obtained after disassembling the battery pack will precipitate crystal salts and adhere to the inner wall of the battery 1 when discharging in the battery 1, thus causing inconvenience in cleaning.

[0093] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
