Pot-type calcining furnace

Abstract

The invention discloses a pot-type calcining furnace. The pot-type calcining furnace consists of two calcining pots which are vertically arranged right and left, a combustion chamber, heating fire ways, air ways, volatilizing subways, a flue, feeding systems and discharging systems, wherein the heating fire ways are arranged on the front sides and the back sides of the calcining pots; inlets of the heating fire ways are connected with the combustion chamber, and outlets of the heating fire ways are communicated with the flue; the volatilizing subways are arranged on the peripheries of the heating fire ways; inlets of the volatilizing subways are connected with volatile discharging ports which are formed on the upper parts of the calcining pots, and outlets of the volatilizing subways are communicated with the heating fire ways; and the air ways are arranged below the heating fire ways and are communicated with the volatilizing subways. The pot-type calcining furnace is simple in structure; volatiles decomposed from raw materials are discharged from the discharging ports on the upper parts of the calcining pots, are mixed with air and pre-heated by the heating fire ways, enter the heating fire ways, and are fully combusted and utilized; the heat efficiency of the whole pot-type calcining furnace is high; the production continuity is high; and the production efficiency is high.

Description

technical field [0001] The invention relates to a calcination furnace, in particular to a pot type calcination furnace used for calcination of raw materials in the production of carbon and graphite products. Background technique [0002] In the industrial production of carbon and graphite products, the main equipment used for raw material calcination is the pot calciner. In the prior art, the furnace body of the tank-type calciner is composed of several calciner tanks with the same structure and vertical arrangement made of refractory bricks. Every four calciner tanks form a group, and each calciner mostly consists of three to six groups, that is, twelve to twenty-four calcining pots are included. The main disadvantages of the above-mentioned pot-type calciner are: 1. A large amount of steel is required for infrastructure construction, as well as special-shaped silica bricks and clay refractory bricks with various specifications, and the investment of the pot-type calciner ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a pot-type calciner to solve the shortcomings of the traditional calciner, such as complex structure, high cost, low heat energy utilization rate and easy occurrence of abnormal phenomena such as coking, furnace blockage or blasting.
