Drying method of enameling machine

Abstract

The invention discloses an enameling machine drying method. The method includes: using an outer cover for collecting gas generated by a varnishing mechanism, feeding the gas into a heat exchange pipe in a drying oven body for heating, conveying the heated gas to a catalytic combustor for reheating the gas to obtain hot gas, and feeding the hot gas into the drying oven body to heating and drying enameled wires. The enameling machine drying method has the advantages that production cost of the drying oven body can be reduced while the pollution gas generated by the varnishing mechanism can be eliminated.

Description

technical field [0001] The invention relates to a drying method and an oven for an enameled machine, in particular to a comprehensive enameled wire production machine including an oven body and a painting mechanism, and belongs to the field of enameled wire manufacturing. Background technique [0002] In the production process, the enameled wire must first go through the annealing process of the aluminum wire. After the annealing process, the aluminum wire is painted by the painting mechanism, and the painted aluminum wire enters the oven for drying. Aluminum wire is enameled wire. The working principle of the existing oven is that a large amount of cresol and xylene gas produced in the enameled wire production process is burned by the catalyst, and then input into the oven furnace through the circulating fan. During the catalytic combustion process, fresh air must be continuously input to maintain the catalytic combustion. Yet produce more cresol and xylene irritating gas ...

AI Technical Summary

Problems solved by technology

In addition, the above-mentioned painting mechanism still has the following problems: 1. The existing painting device generally can only perform one painting process, and it is impossible to repeatedly paint the aluminum wire for multiple times as required, which restricts the painting effect

2. Some enameled wires now have a multi-layer structure according to the functional requirements, and the paint layer of each layer is also different. However, the existing painting device cannot achieve the function of applying multiple layers of different paints at the same time.

3. After the aluminum wire is painted, due to the thick paint attached, it is necessary to wipe the surface of the painted aluminum wire with a felt cotton layer to remove excess paint on the surface of the aluminum wire, so that the surface of the aluminum wire entering the oven has a uniform However, due to long-term operation, the felt cotton layer will be worn due to friction, resulting in an unsatisfactory effect of removing the paint layer on the surface of the aluminum wire, which will lead to a decrease in the performance of the enameled wire
