Calcination furnace

Abstract

The invention provides a calcination furnace and accordingly the structure is simple, the air pollution can be avoided, and dust can be effectively recycled. The calcination furnace comprises a calcination furnace main body and is characterized in that a rolling screen is arranged in the empty chamber formed inside the calcination furnace main body; the calcination furnace main body is provided with the material opening; a vacuum cleaner is arranged above the calcination furnace main body and connected with the calcination furnace main body through a pipe; the calcination furnace main body is connected with a collector through the pipe. According to the calcination furnace, the dust produced in the process of material calcination in a furnace body is absorbed by the pulse vacuum cleaner completely and accordingly the harm to a human body is avoided; more dust is accumulated in the pulse vacuum cleaner in the case of long working hours and accordingly the produced dust is not discharged into the atmosphere directly and accordingly the air pollution is avoided; the dust produced in a vibrating screen can flow into the collector through the pipe directly due to the self-gravity under the condition that the dust cannot be discharged in time and can be recycled and accordingly the cost is saved; the structure is simple and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of calcining equipment, in particular to a calcining furnace. Background technique [0002] As we all know, the calciner is a kind of equipment used for high-temperature treatment, using natural gas, oil and electricity as energy sources, for ironmaking, recovery of rare metals, catalyst production, environmental improvement, and production of special chemicals. In industrial production, the heat preservation of the calciner is very important and has great value. Calciner is mainly used in metallurgy, chemical industry, iron and steel, and other industries. [0003] The furnace will produce a lot of dust before the raw materials enter the furnace body and during the sintering process of the materials in the furnace body. These dusts will cause great harm to the human body and pollute the air. Although the chimney is used for diversion, it cannot Effectively reduce the harm of dust to the human body. At the...

Problems solved by technology

[0003] The furnace will produce a lot of dust before the raw materials enter the furnace body and during the sintering process of the materials in the furnace body. These dusts will cause great harm to the human body and pollute the air. Although the chimney is used for diversion, it cannot Effectively reduce the harm of dust to the human body. At the same time, these dusts are produced with precious raw materials and have extremely high recovery and reuse value.
