Reciprocating single-screw continuous stirring and dispersing device for preparing lithium battery slurry

Abstract

The invention discloses a reciprocating single-screw continuous stirring and dispersing device for preparing lithium battery slurry. According to the technical scheme, the device comprises a disassembly and assembly integrated material mixing barrel, a rod shaft is rotationally connected into the material mixing barrel, two mixing section parts are arranged outside the rod shaft, each mixing section part comprises a first fixing ring, a second fixing ring, a third fixing ring, a spiral pushing blade, a plurality of stirring blades and a spiral shearing blade, the first fixing ring, the second fixing ring and the third fixing ring are sequentially connected to the outer portion of the rod shaft in a threaded mode, the spiral pushing blade is fixed to the outer portion of the first fixing ring, the plurality of stirring blades are fixed to the outer portion of the second fixing ring, the spiral shearing blade is fixed to the outer portion of the third fixing ring, and the spiral pushing blade and the spiral shearing blade are opposite in spiral direction. The reciprocating single-screw continuous stirring and dispersing device for preparing the lithium battery slurry has the advantage of sufficient stirring effect.

Description

technical field [0001] The invention relates to the field of lithium battery production, in particular to a reciprocating single-screw continuous stirring and dispersing device for preparing lithium battery slurry. Background technique [0002] Lithium battery is a relatively green battery, which is widely used. Commonly used materials for polymer lithium-ion batteries include lithium cobaltate, lithium nickelate, lithium manganate, three raw materials, lithium iron phosphate, graphite, conductive carbon black, CMC / PDVF, etc. The filling inside needs to be fully mixed during production. The current mixing method is to use a mixer, but the effect is not good. For this reason, it can be fully mixed by extrusion and push mixing, so it is necessary to use a conveying screw. [0003] Most of the current mixing and dispersing devices use a single screw propeller for extrusion and conveying, and the effect of mixing materials is not very good, so it needs to be improved.
