Description

Technical Field

[0001] The utility model relates to the field of lead paste crushing equipment, in particular to a lead paste crushing device. Background Art

[0002] Lead-acid batteries are a common type of battery in the market today and are commonly used in electric bicycles, automotive batteries, etc. Among them, lead paste is one of the main active substances in lead-acid batteries. The lead paste is located on the positive plate and is mainly composed of lead oxide, basic lead sulfate, metallic lead, lead hydroxide, water, and some additives. During the recycling process of lead-acid batteries, it is also necessary to recycle the lead paste. After the lead paste is recycled, it needs to be crushed into small particles. The existing lead paste crushing devices cannot control the particle size, and there are still some lead paste particles with larger particle sizes after crushing. Therefore, it is particularly necessary to develop a lead paste crushing device that can avoid having larger particle size lead paste after crushing. Summary of the Invention

[0003] The purpose of the utility model is to provide a lead paste crushing device, which has the function of avoiding having larger particle size lead paste after crushing.

[0004] The adopted technical solution is as follows:

[0005] A lead paste crushing device includes a belt conveyor. A chute is arranged at the end of the belt conveyor. The chute is connected to a crushing tank. A discharge valve is arranged at the lower end of the crushing tank. A gantry is arranged at the upper end of the belt conveyor. A lifting frame is arranged on the gantry. A pressing plate is arranged at the lower end of the lifting frame. Multiple vertical plates are arranged on the lower end surface of the pressing plate. A lifting platform is arranged at the upper end of the crushing tank. A rotating shaft is vertically rotatably arranged on the lifting platform. A support is arranged above the crushing tank. A driving mechanism is arranged on the support. The driving mechanism is provided with a telescopic transmission shaft connected to the rotating shaft. Multiple groups of crushing blades are arranged on the rotating shaft in the crushing tank. A mesh plate is arranged on the rotating shaft below the crushing blades.

[0006] Preferably, a limiting ring is arranged on the inner wall of the crushing tank, and the limiting ring is arranged above the mesh plate.

[0007] Preferably, the lifting platform includes a mounting plate. Multiple hydraulic telescopic rods are vertically arranged at the upper end of the crushing tank. The upper ends of the hydraulic telescopic rods are fixedly connected to the mounting plate. A bearing seat is arranged on the mounting plate, and the rotating shaft is installed in the bearing seat.

[0008] Preferably, multiple through holes are formed in the pressing plate, and a top column is slidably arranged in the through hole. The upper end of the top column is fixedly connected to the gantry.

[0009] Preferably, baffles are arranged on both sides of the belt conveyor.

[0010] Compared with the prior art, the beneficial effects are as follows:

[0011] The utility model uses a belt conveyor to convey lead paste, and uses a lifting pressing plate and vertical plates on the pressing plate to cut the lead paste into small pieces. The small pieces of lead paste enter the crushing tank from the chute. A rotating shaft that rotates and reciprocates up and down is used to drive the crushing blades and the mesh plate to rotate and reciprocate up and down. The crushing blades crush the lead paste to a size smaller than the aperture of the mesh plate and then fall below the mesh plate and are discharged from the discharge valve. The lead paste with a larger particle size is crushed multiple times until the particle size is reduced, avoiding the situation that there is still lead paste with a larger particle size after crushing.
