AI Technical Summary

Technical Problem

During the lithium battery manufacturing process, high solid content storage tanks are prone to solid particle sedimentation and stratification during batch-to-batch transport, leading to pipeline blockage. Furthermore, existing flushing methods dilute the solid content and uniformity of subsequent batches of storage tanks, affecting electrode coating quality and battery performance.

Method used

Design a slurry conveying device that uses a residual material cleaning component in the conveying pipeline to push the residual slurry into a second storage tank by means of high-pressure gas or mechanical piston, thereby avoiding pipeline blockage and ensuring that the solid content and uniformity of the slurry are not affected.

Benefits of technology

This effectively avoids pipe blockage, ensures production continuity and electrode coating quality, reduces the risk of slurry dilution, and ensures the solid content and uniformity of the slurry.

Abstract

This application provides a slurry conveying device, including a first storage tank, a second storage tank, a conveying pipeline, a conveying drive, and a residual material cleaning component. The first storage tank is used to store slurry. The second storage tank is spaced apart from the first storage tank. The conveying pipeline connects the first and second storage tanks, defining a conveying path for the slurry. The conveying drive is located on the conveying pipeline and is used to convey the slurry within the pipeline from the first storage tank to the second storage tank. The residual material cleaning component is located on the conveying pipeline, along the conveying path, and is closer to the second storage tank than the conveying drive. The residual material cleaning component is used to draw residual slurry within the conveying pipeline into the second storage tank.
