Hot air circulation and exchange enameled oven

Abstract

The invention discloses a hot air circulation and exchange enameled oven, which comprises a hearth and a heat radiation device arranged in the hearth. The enameled oven is characterized in that: the hearth is sequentially provided with an evaporation zone, an assimilation zone and a drying zone, wherein the upper part of the evaporation zone is provided with a mutually communicated catalytic combustion chamber, the catalytic combustion chamber is provided with an air inlet / outlet, the lateral part of the catalytic combustion chamber is provided with an air homogenizing device, and a passage formed in the air homogenizing device is mutually communicated with the drying zone. The enameled oven has reasonable structure, uniform airflow direction and temperature, energy conservation, environmental friendliness and good popularization value.

Description

technical field [0001] The invention relates to the technical field of enamelled ovens, in particular to an enamelled oven with hot air circulation and exchange. Background technique [0002] The enameled wire industry is a material-heavy industry, mainly composed of two raw materials: copper and lacquer. In the production process, the curing of lacquer to form a film and heating uses a large amount of electric energy, which is a step that consumes the most electricity. In the production process of enameled wire, paint The polycondensation solidification and solvent evaporation are carried out at the same time, and a large amount of solvent evaporation brings out odor and air pollution. At present, the solid content of enameled wire varnish in my country is generally about 32%, and the highest is no more than 40%. The solvent of the lacquer is only needed for chemical synthesis and curing polycondensation, and it is all evaporated into gas during the enameled wire baking pro...

Problems solved by technology

The disadvantage is that the number of stages in the catalytic zone is too small, resulting in a small distance between intervals, and at the same time there is not enough oxygen to mix with the solvent. This structure is not conducive to the full combustion of the solvent; Closed, equipped with iron wire and other metal materials, the back section is a circuitous air duct, the heat energy stored in the iron wire in the closed area of ​​this structure is too high, resulting in the high temperature of the airflow near the closed area in the air distribution device, and the back section is circuitous The air duct can not play the role of uniform wind

It is precisely because there are many problems in the existing equipment, high energy consumption, serious environmental pollution, and damage to human health all hinder the development and progress of the enterprise. Therefore, how to provide an enameled package with high waste gas recovery rate and low energy consumption Oven equipment is not only the needs of enterprises but also the needs of society
