Continuous impurity removal system for lithium ion battery slurry

Abstract

The invention discloses a continuous impurity removal system for lithium ion battery slurry, and relates to the technical field of lithium ion battery preparation. The continuous impurity removal system for the lithium ion battery slurry comprises a first filtering system. The first filtering system comprises a first circulating filtering belt, a first driving part, a first filtering device, a first impurity suction device, a first spray washing device and a first drying device; the first circulating filtering belt sequentially penetrates through the first filtering device, the first impuritysuction device, the first spray washing device and the first drying device; the first driving part is connected with the first circulating filtering belt and used for driving the first circulating filtering belt to circularly rotate in a direction from the first filtering device, the first impurity suction device, the first spray washing device, the first drying device to the first filtering device in sequence, and the first filtering device is used for filtering a lithium ion battery slurry through the first circulating filtering belt. According to the continuous impurity removal system for the lithium ion battery slurry, continuous impurity removal of the lithium ion battery slurry and self-cleaning in the continuous impurity removal process are achieved.

Description

technical field [0001] The invention relates to the technical field of lithium ion battery preparation, in particular to a continuous impurity removal system for lithium ion battery slurry. Background technique [0002] In the existing lithium ion battery slurry impurity removal system, the filter screen is fixedly arranged in the body, and the lithium ion battery slurry is filtered by passing the lithium ion battery slurry through the filter screen. [0003] However, as the use time goes by, a large amount of large particles of impurities will accumulate on the filter screen, and the filter screen needs to be removed frequently for cleaning to ensure the filtering effect. During the process of removing the filter screen for cleaning, the impurity removal system is in a shutdown state. After the filter screen is cleaned and dried, it is reinstalled on the body, and the impurity removal system can run again, which seriously affects the impurity removal efficiency of the impur...

Problems solved by technology

[0003] However, with the passage of time, a large amount of large particles of impurities will accumulate on the filter, and the filter needs to be removed frequently for cleaning to ensure the filtering effect

During the process of removing the filter screen for cleaning, the impurity removal system is in a shutdown state. After the filter screen is cleaned and dried, it is reinstalled on the body, and the impurity removal system can run again, which seriously affects the impurity removal efficiency of the impurity removal system. And then affect the preparation efficiency of lithium-ion batteries

Moreover, the process of frequently disassembling and assembling the filter screen and cleaning and drying the filter screen requires a lot of labor costs
