A heating machine and heating method for raw materials for graphite

Abstract

The invention discloses a heating machine for raw materials of graphite and a heating method. The heating machine for the raw materials of the graphite comprises a heating chamber, stirring rods, an air inlet, a discharge valve and an electric control cabinet, wherein a feeding opening is formed in the upper end of the heating chamber; the stirring motor and a rotating shaft are mutually connected through a coupling; the stirring rods are positioned on two sides of the rotating shaft; the air inlet and an air outlet are mutually connected through an air channel; the discharge valve is positioned at the bottom of the heating chamber; a temperature meter is fixed on a heating cylinder; the electric control cabinet is positioned on one side of the heating cylinder; the heating cylinder and a fan are mutually connected through a heater. Due to adoption of a hot air heating mode, the heating machine for the raw materials of the graphite can be prevented from pollution or corrosion, so that the service life of the heating machine can be effectively prolonged, moreover the contact area of the raw materials of the graphite can be increased, all-direction heating can be achieved, the heating efficiency can be greatly improved, heat in air can be absorbed and conducted into the heating chamber, then the heat loss can be reduced, and the energy can be saved.

Description

technical field [0001] The invention relates to the technical field of heating raw materials for graphite, in particular to a heating machine and a heating method for raw materials for graphite. Background technique [0002] With the rapid development of China's metallurgy, chemical industry, machinery, medical equipment, nuclear energy, automobile, aerospace and other industries, the demand for graphite and carbon products in these industries will continue to grow, and my country's graphite and carbon product industry will maintain rapid growth . When producing graphite, it is necessary to heat the raw material. The heating method usually used is the heating of the box heater, but only one heater is installed in the general box heater, which can only heat part of the graphite. For the middle The darker graphite cannot be heated quickly, which makes the heating very uneven and greatly reduces the heating efficiency; at the same time, direct contact between graphite and the h...
