Description

Technical Field

[0001] The utility model belongs to the technical field of battery recycling, and specifically relates to a recycling and crushing device for waste lithium iron phosphate batteries. Background Art

[0002] Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. It has the advantages of high operating voltage, high energy density, long cycle life, good safety performance, low self-discharge rate, and no memory effect. With the continuous increase in the use of lithium iron phosphate batteries, a large number of waste lithium iron phosphate batteries have been generated. Therefore, the recycling of waste lithium iron phosphate batteries is imperative. The recycling of waste lithium iron phosphate batteries has the advantages of reducing environmental pollution, reducing costs, and saving resources.

[0003] The existing patent (application number: CN202211413345.0) proposes a waste lithium iron phosphate battery recycling and crushing device, including a box body, a feeding port is provided on the top of the box body, a discharge port is provided on the bottom of the box body, a crushing assembly is arranged in the box body, the crushing assembly includes a first crushing tube and a second crushing tube which are symmetrically arranged, and both ends of the first crushing tube and the second crushing tube are rotatably mounted on the inner wall of the box body, a vibrating screen is arranged below the crushing assembly, and the vibrating screen is arranged downwardly in the box body, and an auger feeding conveyor is vertically arranged on one side of the box body, a feeding port is provided at the bottom of the auger feeding conveyor, and the lower end of the vibrating screen extends from the side wall of the box body and is connected to the feeding port, and a discharge pipe is arranged at the top of the auger feeding conveyor, and the outlet of the discharge pipe is located above the feeding port of the box body. The present invention ensures that the waste lithium iron phosphate batteries are fully crushed by arranging a vibrating screen and an auger feeding conveyor, improves the crushing efficiency, and is conducive to subsequent processing.

[0004] The batteries are fed into the crushing rollers in the crushing equipment through the feed port, but the feed port is generally set in the middle of the crushing box and is integrated with the crushing box, so that the batteries enter the crushing box through the feed port and accumulate in the middle of the crushing roller. The batteries cannot be evenly distributed on the crushing roller and crushed at the same time, which reduces the crushing efficiency of the crushing roller.

[0005] In view of this, this application is hereby filed. Utility Model Content
