Roasting device and roasting method for high-purity graphite powder production

Abstract

The invention relates to a high-purity graphite powder processing device which comprises a roasting box and triangular plates. A fixing base is fixed to the arc-shaped side wall of the roasting box, a motor is fixed to the fixing base, and a first transmission wheel is fixed to an output shaft of the motor. An air inlet is formed in the middle of the rear side of the roasting box, a first rotating shaft is arranged in the middle of the front side of the roasting box, two second transmission wheels are fixed to the first rotating shaft, and one second transmission wheel is in transmission connection with the first transmission wheel through a transmission belt. The six triangular plates are annularly and uniformly distributed in the roasting box, and second rotating shafts at the front ends of the triangular plates are in transmission connection with third transmission wheels through clutches. High-purity graphite powder to be processed is put into the triangular plates of the roasting box from a feeding port, the high-purity graphite is roasted through the triangular plates, the distance between the roasting box and the triangular plates prevents the triangular plates from making direct contact with the outside, and the heat loss of the triangular plates is reduced. High-purity graphite powder remaining on the arc-shaped surfaces of the triangular plates is scraped off by cleaning scrapers, and the self-cleaning effect of the device is achieved.

Description

technical field [0001] The invention belongs to the technical field of high-purity graphite processing, and in particular relates to a roasting device and a roasting method for producing high-purity graphite powder. Background technique [0002] High-purity graphite has excellent properties, such as high temperature resistance and corrosion resistance. It is widely used in smelting, chemical industry, EDM, semiconductor, electronic appliances and other industries. High-purity graphite includes high-purity graphite powder and high-purity graphite block two kinds. [0003] During the processing of high-purity graphite powder, high-purity graphite needs to be roasted. After the roasting is completed, the high-purity graphite powder will adhere to the inner wall of the roaster. The graphite powder gradually increases, resulting in a decrease in the roasting effect and affecting the processing efficiency of high-purity graphite. [0004] In view of the existing technical defici...
