Abstract

The invention discloses a stirring and filtering device for lithium battery paste. The stirring and filtering device comprises a main casing, through holes, supporting legs, a putting groove, a discharging pipe, a discharging valve, sliding rods, vibration motors, elastic springs, circular arc clamping plates, sealing blocks, a filtering plate, filtering holes, filtering screens, an electric motor, a rotating shaft, a discharging pipe, fixed frames, stirring rods and stirring blades. The stirring and filtering device for the lithium battery paste has the advantages of reasonable structure, novel design and convenience in discharging; dispersion uniformity of the lithium battery paste is improved; during discharging, the lithium battery paste is filtered so as to remove particles and impurities in the slurry, ensure uniform dispersion of the lithium battery paste and stable subsequent coating and improve the quality of a product; automatic stirring of the lithium battery paste is realized and better dispersion of the lithium battery paste is ensured; moreover, the sealing property of the bottom of the main casing is ensured, and the discharging of the lithium battery paste in the main casing is favorably controlled; the stirring and filtering device has higher practical value and is suitable for popularization and use.

Description

technical field [0001] The invention relates to a stirring and filtering device, in particular to a stirring and filtering device for lithium battery slurry, and belongs to the technical field of application of lithium battery slurry stirring equipment. Background technique [0002] In the electrode manufacturing of lithium-ion batteries, the positive electrode slurry is composed of binder, conductive agent, positive electrode material, etc.; the negative electrode slurry is composed of binder, graphite carbon powder, etc. The preparation of positive and negative electrode slurries includes a series of processes such as mixing, dissolving, and dispersing between liquid and liquid, liquid and solid materials, and this process is accompanied by changes in temperature, viscosity, and environment. [0003] In the process of stirring the slurry, the labor intensity of the laborers is increased, and the stirring efficiency of some stirring devices is poor, and the slurry will not ...
