Description

A waste lithium iron phosphate battery crushing and regeneration device Technical Field

[0001] This utility model belongs to the field of waste lithium iron phosphate battery technology, specifically relating to a waste lithium iron phosphate battery crushing and regeneration device. Background Technology

[0002] Lithium iron phosphate (LFP) batteries are lithium-ion batteries that use lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. They have advantages such as high operating voltage, high energy density, long cycle life, good safety performance, low self-discharge rate, and no memory effect. With the increasing use of LFP batteries, a large number of waste LFP batteries have been generated.

[0003] When recycling spent lithium iron phosphate batteries, the plastic casings and separators of the batteries need to be crushed using a crushing device. To ensure complete crushing, the waste needs to be crushed repeatedly. However, during repeated crushing, smaller particles repeatedly enter the crushing device, occupying crushing space and preventing larger particles from being crushed quickly, thus affecting crushing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a waste lithium iron phosphate battery crushing and regeneration device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste lithium iron phosphate battery crushing and regeneration device, comprising a housing, an inlet at the upper end of the housing, a filter plate at the upper end of the housing, the filter plate being inverted conical in shape and having a through hole in the center, a sleeve at the lower end of the through hole, one end of the sleeve being connected to a conveying pipe, the other end of the conveying pipe passing through the left side of the housing and connected to a crusher, and an oscillating motor being connected to the lower left surface of the filter plate.

[0006] Preferably, the through hole is matched with a sealing rod, the sealing rod passes through the middle of the upper end of the box, the upper end of the sealing rod is connected to a limiting plate, the bottom of the box is provided with an inclined block, and the box is provided with a cover plate on the right side of the inclined block.

[0007] The technical effects and advantages of this utility model are as follows: the filter plate and vibrator can effectively discharge the crushed waste material, avoid occupying the crushing space, and improve the crushing efficiency. Attached Figure Description

[0008] Figure 1 is a schematic diagram of this utility model;

[0009] Figure 2 is a schematic diagram of the filter plate of this utility model.

[0010] In the diagram: 100 housing, 110 feed inlet, 120 inclined block, 130 cover plate, 200 limiting plate, 210 sealing rod, 300 filter plate, 310 through hole, 320 sleeve, 330 conveying pipe, 400 vibrating motor, 500 crusher. Detailed Implementation

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] This utility model provides a waste lithium iron phosphate battery crushing and regeneration device as shown in Figures 1-2, including a box body 100, a feed inlet 110 at the upper end of the box body 100, a filter plate 300 at the upper end of the inside of the box body 100, the filter plate 300 is in the shape of an inverted cone and has a through hole 310 in the center, a sleeve 320 at the lower end of the through hole 310, one end of the sleeve 320 is connected to a conveying pipe 330 at the lower end, the other end of the conveying pipe 330 passes through the left side of the box body 100 and is connected to a crusher 500, and an oscillating motor 400 is connected to the lower left surface of the filter plate 300.

[0013] In some specific embodiments of this utility model, the through hole 310 is matched and connected to the sealing rod 210, the sealing rod 210 penetrates the middle of the upper end of the box 100, the upper end of the sealing rod 210 is connected to the limiting plate 200, the bottom of the box 100 is provided with an inclined block 120, and the box 100 is provided with a cover plate 130 on the right side of the inclined block 120.

[0014] In use, the through hole 310 is blocked by the sealing rod 210, and then the crushed waste is poured in through the feed port 110. The oscillating motor 400 is started to make the waste that meets the requirements fall from the hole of the filter plate 300 onto the inclined block 120 at the bottom of the box 100. When a certain amount is accumulated, the cover plate 130 can be opened for collection. For waste that does not meet the requirements, the sealing rod 210 is pulled out so that it flows into the crusher 500 for secondary crushing.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
