Novel spherical graphite multi-polarity fine purification machine

Abstract

The invention discloses a novel spherical graphite multi-polarity fine purification machine which structurally includes a bracket, a drying box, a water outlet valve, a purification box, a steam valve, a feeding port, a stirring device, a water pipe, a water box and a control box. The bracket is welded to the bottom of the purification box, the water outlet valve is connected to the bottom side surface of the purification box, the water box is arranged above the purification box and communicates with the top of the purification box through a water pipe, the feeding port is formed in the side surface of the top of the purification box, and the steam valve is arranged on the side surface of the purification box; the control box is installed on outside the purification box, the drying box isconnected to the bottom of the purification box, and the stirring device is installed inside the purification box; and the stirring device is electrically connected with the control box. The novel spherical graphite multi-polarity fine purification machine has the beneficial effects that a rotating strip composed of a pull ring and an airbag replaces a stirring blade, due to the elasticity of theairbag can buffer when colliding with graphite occurs, abrasion on the graphite surface is avoided, the surface integrity of the graphite is ensured, the rotating strip continuously move up and down through the action of magnetic poles, stirring is more comprehensive, and the stirring effectiveness is improved.

Description

technical field [0001] The invention relates to the field of graphite, in particular to a novel spherical graphite multi-polarized fine purifier. 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. Material replacement products. It has excellent electrical conductivity and chemical stability, high charge and discharge capacity, long cycle life, and is environmentally friendly. [0003] At present, when the spherical graphite is purified, the agitator is used for agitation. The material of the agitator is relatively hard, and it will collide with the graphite during rotation and agitation. integrity. Contents of the invention [0004] The main ...
