[0021] The embodiment of the present application solves the problem that during the battery waste acid recovery process, a small amount of plastic and metal are crushed into fine particles and pass through the filter frame into the electrolyte pool below, resulting in the need to add more steps for subsequent electrolyte treatment, which is very inconvenient.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model embodiment discloses battery waste acid recovery equipment.

[0025] When in use, the inclined water tank 11 is installed under the waste battery crusher. The crushed waste batteries and waste acid liquid fall down to the fixed mesh plate 12 and the flip mesh plate 13. Large pieces of solid waste are discharged outward along the guide plate 14, and small particles of solid waste will flow down into the interior of the inclined water tank 11 along with the waste liquid, waiting to be cleaned.

[0026] The acid overflow mechanism 2 includes a connecting pool 21, a central horizontal flow pipe 22 and a countercurrent mesh plate 23. The connecting pool 21 is fixedly arranged on one side of the acid filter and recovery frame 1. The connecting pool 21 is connected to the acid filter and recovery frame 1 through the central horizontal flow pipe 22. The end of the central horizontal flow pipe 22 extends to the middle of the acid filter and recovery frame 1. The countercurrent mesh plate 23 is fixedly installed in the middle of the connecting pool 21; the connecting pool 21 is fixedly installed on one inclined end of the inclined water tank 11, and the end of the central horizontal flow pipe 22 is fixedly plugged with a water outlet mesh plate 26, and the water outlet mesh plate 26 is directly opposite to the inner bottom of the inclined water tank 11. A fixing frame 24 is fixedly welded inside the connecting pool 21, and the countercurrent mesh plate 23 is fixedly installed on the top of the fixing frame 24 by bolts. An overflow pipe 25 is fixedly welded on the outer wall of the connecting pool 21.

[0027] The waste liquid enters the central horizontal flow pipe 22 through the outlet mesh plate 26, then enters the connecting tank 21, then goes upward through the countercurrent mesh plate 23, and finally is discharged through the overflow pipe 25, thereby effectively avoiding the presence of metal impurities and scum in the discharged waste acid liquid and reducing the subsequent waste slag cleaning steps.

[0028] The debris cleaning mechanism 3 includes a sediment collecting bucket 32 ​​arranged at the bottom of the acid liquid filter recovery frame 1 and a floating object scraper plate 34 cyclically slidably arranged at the top of the acid liquid filter recovery frame 1.

The floating object scraper plate 34 is fixedly installed on the outer surface of the conveyor belt 33.

[0029] The scum in the acid solution is driven by the conveyor belt 33 to circulate the floating scraper plate 34, scraping the scum into the scum collection bin 31 and then cleaning it outward. At the same time, the metal debris settles downward and slides along the bottom of the inclined water tank 11 into the sediment collection bucket 32.
