[0014] The present invention provides a lead-acid battery material crushing and recovery device. It has the following beneficial effects:

[0015] (1) In the lead-acid battery material crushing and recovery device, the air rod moves slowly, driving the support plate to move slowly so that the two blanking plates can only move slowly back to back to release the seal of the blanking frame, so that the lead-acid battery to be crushed slowly falls into the crushing frame for crushing. Slowly entering the crushing frame helps to reduce the scattering of dust and fragments generated during mechanical crushing, which is beneficial for controlling particulate pollution in the environment and preventing harmful substances from spreading to the surrounding area. At the same time, after the lead-acid battery on the surface of the blanking plate falls into the crushing frame, the blanking plate restores the seal of the blanking frame under the elastic force of the No. 1 spring. Harmful gases, such as lead vapor, may be generated during the battery crushing process. Sealed crushing can effectively prevent these harmful gases from spreading to the operating environment and protect the health of the workers.

[0016] (2) The lead-acid battery material crushing and recovery device drives the crushing device to shake by the impact of the bumps on the receiving plate. The lead-acid battery material may get stuck or cause blockage in the crushing device when it is crushed. The shaking device can help break this dilemma. By shaking, the lead-acid battery will flow and grind more evenly, reducing the possibility of getting stuck in the equipment and ensuring the smooth progress of the production process. At the same time, the extrusion rod rotates and contacts the sealing block to squeeze the sealing block to move. The sealing block moves to release the seal on the drip hole and leak the drip hole. The lubricating oil inside the drip frame drips to the connection between the crushing device and the crushing frame through the drip hole. The lubricating oil can reduce the friction between the metal surfaces at the connection, thereby reducing wear, helping to extend the service life of the connection and reduce wear and damage to parts.

[0017] (3) The lead-acid battery material crushing and recovery device moves the two hollow rods in opposite directions by moving the hollow plate downward to scrape the dead corners of the inner wall of the placement frame. The dead corners are usually where electrolyte accumulates and remains. If scraping is not performed, some electrolyte may remain in the equipment, affecting the crushing of the next batch of lead-acid batteries. By scraping the dead corners, the residual electrolyte can be reduced and the cleanliness of the equipment can be ensured when processing different types of materials.

[0018] (4) The lead-acid battery material crushing and recycling device accelerates the discharge speed of the crushed lead-acid batteries by rotating the strip plates to push the crushed lead-acid batteries on the surface of the filter plate. Accelerating the discharge speed can significantly improve the overall efficiency of the production line. During the battery recycling process, if the discharge speed can be effectively improved, the production capacity of the entire production line will also increase accordingly. At the same time, the rotation of the strip plates pushes the crushed lead-acid batteries on the surface of the filter plate and accelerates the solid-liquid separation speed, thereby improving the working efficiency of the entire device.
