A continuous and rapid roasting equipment for powder or granular materials

Abstract

The invention provides continuous quick roasting equipment for powder or particle materials, and the equipment is suitable for the field of lithium batteries. In the equipment, the to-be-roasted materials fall into roasting discs on the top from distribution hoppers, rotary shafts below the current roasting discs are controlled to rotate after roasting is carried out for a period of time, the materials in the discs are poured into roasting discs on the lower layer and continue to be roasted, similarly, the materials in the roasting discs on the second layer continue to be poured into roastingdiscs on the third layer, the operation is conducted repeatedly till the materials in roasting discs on the lowermost layer are poured out, finally the materials fall out of discharge hoppers at the bottom, and the process is carried out repeatedly; and if the current roasting discs contain the materials, only after the materials in the discs are poured to the roasting discs on the lower layer canthe roasting discs receive the materials from the roasting discs on the upper layer. As the materials scatter into the roasting discs of the lower layer when transferred from one roasting disc to thenext roasting discs, the materials are roasted in a furnace more safely through a plurality of cycles, the effect is better, and besides, as the materials are continuously roasted, the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of lithium batteries, in particular to a continuous and rapid roasting equipment for powder or granular materials. Background technique [0002] Roasting is the physical and chemical reaction process of solid materials heated at high temperature without melting, and the chemical properties and physical composition of the materials are changed for the next step of processing. Roasting includes oxidation, pyrolysis, reduction, halogenation, etc., and is usually used in inorganic chemical and metallurgical industries. There are two types of roasting process with additives and without additives. [0003] The roasting furnace is a common roasting equipment. There are heating wires on the inner wall. There is a roasting pan inside the roasting furnace, and the powder or granular material to be roasted is placed in the pan. At present, after the materials are put into the roasting furnace together with the roasting pan, th...
