Description

Technical Field

[0001] The present invention relates to the field of lithium iron phosphate battery recycling, and in particular to a lithium iron phosphate battery recycling device with a self-cleaning effect. Background Art

[0002] Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. The rated voltage of the single cell is 3.2V and the charging cut-off voltage is 3.6V~3.65V. After long-term use, the lithium iron phosphate battery needs to be scrapped and recycled. Therefore, a recycling device is needed to recycle the positive electrode of the lithium iron phosphate battery. However, the lithium iron phosphate battery recycling device in the existing technology does not have a self-cleaning structure. When the positive electrode is crushed and recycled, a large amount of lithium iron phosphate powder is adsorbed on the inner wall of the crushing mechanism, which is not only inconvenient to clean it, but also causes waste of materials.

[0003] Therefore, a recycling device for lithium iron phosphate batteries with a self-cleaning effect is proposed to solve the above problems. Summary of the Invention

[0005] Preferably, the dust scraping and suction assembly includes a shell installed at the bottom of the inner cavity of the pulverizing mechanism body, the top of the shell is connected to a steel pipe through a bearing rotation, the top of the steel pipe is connected to a tee pipe, the top of the tee pipe passes through the sieve plate and extends to the top of the sieve plate, scrapers are installed on both sides of the top of the sieve plate, dust suction ports are opened on the front and back sides of the scraper, both ends of the tee pipe are connected to a transverse pipe, the end of the transverse pipe away from the tee pipe is connected to the scraper, the scraper can be used to scrape the inner wall of the pulverizing mechanism body, thereby cleaning the inner wall of the pulverizing mechanism body.

[0006] Preferably, a sealing gasket is provided at the connection between the shell and the steel pipe, which is made of rubber to seal the connection between the shell and the steel pipe, thereby preventing leakage from occurring at the connection between the steel pipe and the shell during rotation, thereby affecting the absorption of the powder.

[0007] Preferably, a feed pump is installed on one side of the bottom of the inner cavity of the crushing mechanism body, the air inlet end of the feed pump is connected to one side of the shell, and the air outlet end of the feed pump passes through the crushing mechanism body and extends to the outside of the crushing mechanism body, so that the powder floating after scraping can be sucked through the dust suction port to avoid the powder being re-adsorbed on the inner wall of the crushing mechanism body.

[0008] Preferably, a storage box is installed at the bottom of one side of the crushing mechanism body, and the storage box is arranged on the surface of the air outlet end of the feed pump. One side of the storage box is connected to a movable door by a hinge, and a handle is installed on the surface, which can store the powder after absorption, so as to facilitate its subsequent reuse.

[0010] The beneficial effects of the present invention are:

[0011] 1. By setting an automatic cleaning mechanism, when cleaning the lithium iron phosphate powder adsorbed on the inner wall of the pulverizing mechanism body, the power component drives the steel pipe to rotate. The steel pipe drives the sieve plate to rotate when the steel pipe rotates by using a bearing connection. The sieve plate drives the top tee pipe and the scraper to rotate, and the lithium iron phosphate powder on the inner wall of the pulverizing mechanism body is scraped off. Then, the suction force generated by the feed pump is transmitted to the inner cavity of the steel pipe through the connection between the feed pump and the shell. Then, the suction force is transmitted to the inner cavity of the scraper through the horizontal pipe through the connection between the steel pipe and the tee pipe. The scraped powder is sucked through the dust suction port, which facilitates the automatic cleaning of the inner cavity of the pulverizing mechanism body, stores the sucked powder, and reuses the powder. At the same time, it can avoid the inconvenience of cleaning the powder and the waste of materials.

[0012] 2. By setting up a power component, when driving the sieve plate to rotate, the motor drives the driving gear to rotate, and the driving gear and the driven gear drive the steel pipe to rotate through the transmission connection of the transmission belt, and then the sieve plate is driven to rotate through the fixed connection between the outer wall of the steel pipe and the sieve plate, which provides power support for the sieve plate when it rotates, and facilitates the effect of automatic cleaning.

The sieve plate 3 drives the top tee pipe 213 and the scraper 214 to rotate, scraping the lithium iron phosphate powder on the inner wall of the crushing mechanism body 1, and then the suction force generated by the feed pump 217 is transmitted to the inner cavity of the steel pipe 212 through the connection between the feed pump 217 and the shell 211, and then the suction force is transmitted to the inner cavity of the scraper 214 through the connection between the steel pipe 212 and the tee pipe 213 through the horizontal pipe 216, and the scraped powder is sucked through the dust suction port 215, so as to achieve the effect of automatic cleaning of the powder; a storage box 218 is installed at the bottom of one side of the crushing mechanism body 1. The storage box 218 is arranged on the surface of the air outlet end of the feed pump 217.
