Cyclic baking method of enamelled wire and oven for realizing method

Abstract

The invention relates to a cyclic baking method of an enamelled wire and an oven for realizing the method. According to the method, after an enamelled wire attached with painted liquid enters a hearth through an inlet entrance of an oven, the painted liquid, which is under the effect of an inner temperature of the oven, starts to be evaporated to generate a certain amount of solvent vapor; the solvent vapor is conveyed to a first level catalytic combustor for combustion so as to generate high temperature airflows, wherein the temperature of the airflows is higher than the temperature that is required by the technology; and one part of high temperature airflows directly pass through an air distribution device and a voltage stabilization device and are conveyed to a baking channel to bake the enamelled wire; and the other part of high temperature airflows are sent to a heat exchanger for heat exchange and then the airflows is discharged from an exhaust gas flue; and the heat exchanger absorbs waste heat of the exhaust gas and the absorbed waste heat is sent to the baking channel at the inlet entrance for baking the enamelled wire. According to the invention, the structures of the devices employed in the invention are simple; an enamelling production efficiency is high; there are no limits for production specifications and varieties; power consumption is reduced; and energy is saved and the environment is protected.

Description

technical field [0001] The invention relates to a cycle baking method for enameled wires and an oven for realizing the method. Background technique [0002] The enameled wire industry is a material-heavy and high-energy-consuming industry. During the enameled wire coating and baking process, the polycondensation and curing of the paint and the evaporation of the solvent are carried out at the same time. If it is directly discharged into the air after evaporation, it will cause environmental pollution; there are also some enameled wire manufacturers who directly discharge the heat generated after the solvent is burned through the catalytic chamber, resulting in a waste of energy. Therefore, it is necessary to improve the structure of the enameled wire oven, make full use of various existing heat, and achieve the purpose of reducing power consumption, improving production efficiency and protecting the environment. [0003] The existing improved enameled wire oven generally ad...

Problems solved by technology

[0003]The existing improved enameled wire oven generally adopts hot air circulation for heat circulation treatment. The hot air in the oven is heated after catalytic reaction, and then the fan blows the hot air It is sucked out and sent back to the oven. During this process, the wind speed and air pressure are not easy to control and adjust, resulting in uneven heat distribution, reducing the uniformity of film formation on the product surface, and restricting the volume and product specifications of the oven.
