Stirring device of high-speed dispersion equipment

Abstract

The invention discloses a stirring device of high-speed dispersion equipment. The stirring device comprises a dispersion barrel, a dispersion wheel and a spindle. A barrier is arranged at the upper end of the dispersion barrel, a discharge cavity is formed on the upper side of the barrier, a through hole is formed in the center of the barrier, a dynamic screen cloth separator which is of a conical structure is arranged at the through hole in the barrier, a flow guide plate is arranged above a feed inlet, the section of the dispersion wheel is in the shape of a conical structure, the flow guide plate is arranged at the lower end of the dispersion wheel, supports are arranged between the dispersion wheel and the dispersion barrel, and a plurality of via holes are formed in the supports. The stirring device with the structure has the advantages that slurry is forced to be distributed peripherally and participates in dispersion procedures of the dispersion wheel, the consistency of the flow speeds of the slurry in a cavity can be guaranteed by the dispersion barrel which is of a conical structure, and the slurry can be sufficiently and uniformly dispersed; homogenized dispersion effects can be realized by the aid of the dynamic screen cloth separator which is of the conical structure, certain guide effects can be realized by the conical structure, good discharge and heat dissipation effects can be realized, and accordingly the quality of the slurry can be guaranteed.

Description

technical field [0001] The invention relates to a slurry dispersing equipment, in particular to a stirring device of a high-speed dispersing equipment. Background technique [0002] The mixing and dispersing process of lithium battery cell slurry has a great influence on the quality of the product in the entire production process of lithium ion batteries, and is the most important link in the entire production process. For 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. In the positive and negative electrode slur...

Problems solved by technology

[0004] Yet existing this dispersing device has following shortcoming: after slurry enters dispersing barrel at the bottom, due to the effect of slurry pump, it is possible to pass directly into discharge part from the hole of dispersing wheel, and does not participate in the suction of dispersing wheel , throwing out, hitting, returning and re-inhaling, resulting in uneven particle size of the outlet slurry, which affects the quality of the slurry; in addition, the flow rate of the slurry in the dispersion tank is different, resulting in uneven dispersion of the slurry, which further affects the slurry. quality

[0005] In addition, for high-speed dispersing equipment, the heat dissipation of the material tank is a very important link. The existing heat dissipation stirring device has an unreasonable heat dissipation structure design and uneven heat dissipation.
