Horizontal enameling machine oven with ultra-wide combustion chamber

Abstract

The invention discloses a horizontal enameling machine drying oven with a superwide furnace which comprises furnace and heat irradiation equipment arranged in the furnace, wherein, the upper part of the furnace is provided with a catalytic combustor and a catalytic post suction and discharge room which are communicated. Two ends of the catalytic combustor are provided with an air inlet and an air outlet, a heat exchange room is arranged on the periphery of the catalytic post suction and discharge room, and the furnace is separated from a solvent suction and discharge area in the middle. The horizontal enameling machine drying oven is characterized in that more than two air inlets are arranged in the solvent suction and discharge area and the air inlet of the catalytic combustor is respectively communicated with the air inlets at the ends of the furnace and in the solvent suction and discharge area. A multi-channel air-flow distribution device is arranged in the catalytic post suction and discharge room and comprises a solvent distillation channel, the left and right sides and the back end of the channel are all provided with stream inlets, and the middle part thereof is provided with an air flow demarcation strip; and a pump line provided with an exhaust fan is arranged on the periphery of the air flow demarcation strip and communicated with the solvent distillation channel. The horizontal enameling machine drying oven has reasonable structure, uniform airflow direction and temperature, energy conservation and environmental protection, and good popularization value.

Description

technical field [0001] The invention relates to the technical field of enamelling machines, and more specifically relates to an oven structure of a horizontal enamelling machine. 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 enamele...

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 a high waste gas recovery rate, low energy consumption, furnace and Enamelling equipment with balanced temperature inside the oven is not only the need of enterprises but also the need of society
