[0002] With the rapid development of technology and the continuous improvement of people's living standards, the use of batteries is increasing daily. Acid leaching is a crucial step in the recycling of used batteries. The main purpose of acid leaching is to dissolve the valuable metals in the used batteries into an acid solution, so that they can be recovered through various separation and purification processes. Existing acid leaching equipment for used battery recycling typically involves crushing the electrodes of the used batteries and placing them into a reaction vessel containing acid. Heating and stirring are used to ensure that the electrode materials come into full contact with the acid solution, causing a chemical reaction that dissolves the valuable metals.

[0003] However, after the acid leaching process, electrode debris remains in the acid leaching solution. To ensure the continued use of the acid leaching solution, it cannot be directly discharged. Therefore, when collecting this electrode debris, it is usually necessary to first turn on the acid leaching equipment and then use a retrieval device to retrieve the acid-leached electrode debris. This often requires multiple retrievals and is prone to incomplete retrieval. At the same time, the stirring components of the acid leaching equipment can easily interfere with the retrieval process, making the operation cumbersome. To address these problems, an acid leaching equipment for waste battery recycling is needed. Utility Model Content

[0004] The technical problem this invention aims to solve is that during continuous acid leaching, the removal of waste battery electrode debris is troublesome and the removal effect is poor. At the same time, the stirring component can easily interfere with the removal of debris.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] according to Figure 1-4 As shown: This utility model provides an acid leaching device for recycling waste batteries: it includes an acid leaching cylinder 1, an end cap 2 on the acid leaching cylinder 1, and an acid solution stored in the acid leaching cylinder 1; a slot 9 is provided on the acid leaching cylinder 1, and a locking block 8 fixedly connected to the bottom of the end cap 2 is provided in the slot 9 to increase the sealing of the connection between the end cap 2 and the acid leaching cylinder 1. A heating block 6 is provided on the inner wall of the acid leaching cylinder 1 to provide a suitable reaction temperature, and an outlet pipe 5 is connected to the bottom of the acid leaching cylinder 1; it also includes:

[0022] The mesh-like placement cylinder 7 and the stirring assembly are fixedly connected to the bottom of the end cap 2; the stirring assembly is connected to the end cap 2 and is located inside the placement cylinder 7; the end cap 2 has a feed hole 4 corresponding to the placement cylinder 7, and a screw plug is threaded into the feed hole 4. Electrode fragments can be directly added into the placement cylinder 7 through the feed hole 4.

[0023] like Figure 4 As shown, the stirring assembly includes a stirring motor 3, a rotating shaft 17, and stirring blades 18. The stirring motor 3 is mounted on the end cover 2, and the rotating shaft 17 is fixedly connected to the output shaft of the stirring motor 3, with the rotating shaft 17 located inside the placement cylinder 7. The stirring blades 18 are fixedly connected to the rotating shaft 17. By setting up the stirring assembly, the reaction between the acid solution and the electrode fragments can be accelerated.

[0024] The end cap 2 has a connecting groove 10, and the placement cylinder 7 is inserted into the connecting groove 10; the outer wall of the placement cylinder 7 has a fixing hole 11, and the end cap 2 has a groove 15; an elastic insertion component is provided in the groove 15, and the elastic insertion component is inserted into the fixing hole 11.

[0025] like Figure 3 As shown, the elastic insertion assembly includes a insertion rod 14, a spring 13, and a fixing plate 12. The insertion rod 14 is located in the groove 15 and inserted into the fixing hole 11. The fixing plate 12 is fixedly sleeved on the insertion rod 14, and the spring 13 is sleeved on the insertion rod 14, with the spring 13 positioned corresponding to the fixing plate 12. A countersunk hole 16 is provided on the outer wall of the end cap 2, and the operating end of the insertion rod 14 is located in the countersunk hole 16, making it convenient for workers to avoid accidentally touching the insertion rod 14. The spring 13 has a reserved compression amount, which can continuously exert pressure on the fixing plate 12, thereby increasing the stability of the insertion rod 14 inserted into the fixing hole 11.

[0026] The principle of this utility model

[0027] like Figure 1 , 2 As shown, the acid leaching cylinder 1 contains an acid solution, and the mesh-like placement cylinder 7 ensures that the acid solution can enter the placement cylinder 7 normally. Open the screw plug of the feed port 4 and add electrode fragments into the placement cylinder 7 through the feed port 4, allowing the electrode fragments to react with the acid solution. Start the stirring motor 3 and the heating block 6 to accelerate the reaction between the electrode fragments and the acid solution at a suitable temperature. After the reaction is complete, the electrode waste in the placement cylinder 7 needs to be removed; such as... Figure 2 As shown, the end cap 2 can be opened directly. Since the placement cylinder 7 is fixedly connected to the bottom of the end cap 2, when the end cap 2 is opened, the placement cylinder 7 can be directly separated from the acid immersion cylinder 1 and the acid solution, which quickly and conveniently completes the removal of electrode waste, and there is no need to worry about the stirring component affecting the removal of electrode waste.

[0028] At this point, although the electrode waste has been removed from the acid leaching cylinder 1, it still remains in the placement cylinder 7, such as... Figure 3 , 4 As shown, pulling the insertion rod 14 disengages it from the fixing hole 11, quickly releasing the fixed connection to the placement cylinder 7 and completing the separation of the stirring component from the placement cylinder 7. At this point, the electrode waste inside the placement cylinder 7 can be easily poured out, completing the removal and recycling of the electrode waste. Then, the placement cylinder 7 is inserted back into the connecting groove 10, and the insertion rod 14 is used to re-fix the placement cylinder 7, allowing the electrode to continue acid leaching.
