Slurry stirring device for lithium battery electrode

Abstract

The invention discloses a slurry stirring device for a lithium battery electrode. The device comprises a vacuum pump, a first stirring shaft, an air exhaust head, a barrel cover, stirring wings, a stirring barrel, a discharging valve discharging head, a base, a second motor, a hydraulic pump station, a spring, a damper, a bottom plate, an arc-shaped steel disc, universal wheels, a first hydrauliccylinder, a mounting plate, a damping plate, a vertical plate, a second stirring shaft, a second stirring rod, scrapers, a first stirring rod, a second hydraulic cylinder, an air pipe, a top plate, afirst motor, a clamping ring, a pressure relief pipe, a pressure relief valve, a pressure meter and a groove. The slurry stirring device comprises a first stirring mechanism and a second stirring mechanism, so that raw materials are uniformly stirred, precipitate of the raw materials is avoided, stirring of the raw materials is facilitated, stirring time is shortened, vertical force generated by vibration is reduced by the damper and the arc-shaped steel disc when the device runs, vibration generated in running of the device is greatly reduced, so that noise is reduced, and reduction of noisepollution is facilitated.

Description

technical field [0001] The invention relates to a stirring device, in particular to a slurry stirring device for lithium battery electrodes, belonging to the technical field of lithium battery production equipment application. Background technique [0002] Lithium batteries refer to batteries containing lithium in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are usually non-rechargeable and contain lithium in metallic state. Lithium ion batteries It does not contain metallic lithium and is rechargeable. Currently, rechargeable lithium-ion batteries are more popular on the market. During the production of lithium-ion batteries, the main structure for generating electricity from lithium ions is the electrode. When the electrode is manufactured, the slurry Material mixing is an essential process, so a slurry mixing device will be used. [0003] Most of the ex...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing slurry stirring devices for lithium-ion battery electrodes only contain one stirring mechanism. When stirring raw materials, it is easy to cause uneven stirring and precipitation of raw materials. Moreover, when the existing stirring devices are stirring, the raw materials are easy to Adhering to the inner wall of the mixing tank, the raw materials are not easy to be stirred, and the stirring time of the raw materials is longer, the stirring efficiency is poor, and most of the existing stirring devices do not contain a shock absorbing mechanism. When the device is working, it will produce Stronger vibration produces stronger noise, and there is stronger noise pollution
