Abstract

The invention discloses a powder flowing system of a lithium ion battery diaphragm. The powder flowing system comprises a bag throwing station, two material-gas separators and a vacuum pump, wherein an air blower is arranged below the bag throwing station, a vacuumizing opening is formed in the top of each material-gas separator, a feeding opening is formed in the side face of each material-gas separator, a discharging opening is formed in the bottom of each material-gas separator, and a stirring device is arranged on the wall face of the bag throwing station. A feeding port of one material-gas separator is connected with a discharging port of a bag throwing station through a pipeline, a feeding port of the other material-gas separator is connected with an additive storage tank through a pipeline, vacuumizing ports of the two material-gas separators are connected with a vacuum pump through pipelines respectively, a buffer hopper is arranged below each material-gas separator, a double-screw conveyor is arranged at an outlet of each buffer hopper, a batching scale is arranged on the lower portion of each buffer hopper, two batching screws meshed in the same direction are arranged in each double-screw conveyor, outlets of the two double-screw conveyors are communicated into the batching scales, and a stirring bin, a metal separator and a feeding weightlessness scale are sequentially arranged below each batching scale from top to bottom.

Description

Technical field [0001] The present invention relates to a powdery flow system for a lithium ion battery diaphragm, belonging to the field of production and manufacturing of lithium ion battery diaphragm.
