Description

technical field [0001] The invention relates to the field of lithium ion battery processing and manufacturing, in particular to a slurry constant temperature system for a buffer tank of a lithium ion battery coating machine. Background technique [0002] At present, with the continuous increase of industrial production requirements for square lithium-ion batteries, the market has higher and higher requirements for production equipment of lithium-ion batteries. In order to improve the market competitiveness of pulp mixing equipment in lithium-ion battery production equipment, people have The requirements for slurry performance during the slurry buffering process of the equipment are becoming more and more stringent. The temperature of the pulp produced by the mixing equipment is unstable and the temperature of the pulp is lowered during storage, which will lead to poor pulp performance. [0003] Patent document with publication number CN210730017U discloses a battery slurry ...

Problems solved by technology

The unstable temperature of the slurry produced by the mixing equipment and the decrease of the slurry temperature during storage will lead to poor performance of the slurry

[0003] The patent document with the publication number CN210730017U discloses a device for improving the consistency of battery slurry for coating, which includes a slurry active pumping mechanism, a slurry buffer mechanism, and a slurry constant temperature mechanism. The slurry active pumping mechanism is connected to the slurry buffer. Mechanism, the slurry constant temperature mechanism is used to keep the slurry in the slurry buffer mechanism at a constant temperature. In the prior art, the slurry buffer container is set in a constant temperature water bath. When the actual temperature of the coating slurry is higher or lower than the system design When setting the value, the cooling or heating function cannot be selected according to the actual temperature, resulting in unstable performance of the coating slurry
