Slurry turnover tank and method avoiding viscosity difference of slurry in turnover tank

Abstract

The invention discloses a slurry turnover tank and a method avoiding the viscosity difference of slurry in the turnover tank. The slurry turnover tank comprises a tank body. The upper portion of the tank body is connected with a slurry feeding pipe, and the bottom of the tank body is connected with a slurry discharging pipe. A plurality of circulation pipes are evenly distributed on the circumference of the outer portion of the tank body and provided with pumps. The circulation pipes are vertically arranged, and the upper ends and the lower ends of the circulation pipes communicate with the interior of the tank body. The slurry turnover tank and the method avoiding the viscosity difference of slurry in the turnover tank have the beneficial effects that up-down circulation of slurry in theturnover tank can be achieved, it is guaranteed that slurry at the top and slurry at the bottom are consistent in viscosity, and a foundation is laid for coating face density stability; bubbles can beeffectively prevented from being guided into the slurry, and the slurry state is guaranteed; and production noise can be effectively lowered through usage of screw pumps.

Description

technical field [0001] The invention relates to the technical field of turnover tanks, in particular to a slurry turnover tank and a method for solving the viscosity difference of slurry in the turnover tank. Background technique [0002] In the lithium-ion battery mixing process, after the slurry is combined, it needs to be pumped into the turnover tank first, and then discharged from the turnover tank for the coating process. When the slurry is stored in the turnover tank, although the stirring paddle in the turnover tank is stirring all the time, the slurry will settle due to the slow stirring speed, resulting in the viscosity at the bottom being higher than that at the top, and the viscosity of the slurry gradually changes during the discharging process. Small, the consistency cannot be guaranteed, resulting in unstable coating surface density. [0003] Ensuring that the upper, middle and lower parts of the slurry in the turnover tank are in the same state and the same ...
