Graphite negative-pressure feeding device

Abstract

The invention discloses a graphite negative-pressure feeding device. The graphite negative-pressure feeding device comprises a feeding bin, a feeding air pipe and a pulse dust remover; a screening plate is arranged at the upper part of the feeding bin; the feeding air pipe is horizontally arranged under the feeding bin, and the side wall of the feeding air pipe communicates with the bottom of thefeeding bin; one end of the feeding air pipe is an air inlet, and the other end is connected with the pulse dust remover; a flow adjusting valve is arranged on a pipeline of the feeding air pipe; an air outlet of the pulse dust remover is connected with an induced draft fan; a spiral unloader is vertically arranged in a hopper of the pulse dust remover; a spiral feeder is horizontally arranged atthe bottom of the hopper of the pulse dust remover; and an outlet of the spiral feeder is connected with a graphite negative-pressure material use system. The device can guarantee continuous and stable feeding of graphite and guarantee normal production.

Description

technical field [0001] The invention relates to the technical field of graphite production, in particular to a graphite negative pressure feeding device. Background technique [0002] Spherical graphite material has good electrical conductivity, high crystallinity, low cost, high theoretical lithium intercalation capacity, low and flat charging and discharging potential, etc. It is an important part of lithium-ion battery negative electrode material and is the negative electrode for lithium-ion battery production at home and abroad.
