Energy-saving enamelled wire oven

Abstract

The invention discloses an energy-saving enamelled wire oven. The energy-saving enamelled wire oven includes an oven body, a first electrical heating tube, an air evening plate, a circulating blower fan, a second electrical heating tube, a catalysis combustor, and a heat exchanger. The oven body has a hearth. A pair of filter plates is symmetrically arranged on the upper portion of the hearth. The filter plates, the sidewall of the oven body and the top end face of the oven body are connected together to form a purifying chamber. An exhaust channel extending outside the oven body is formed between the filter plates. The exhaust channel is equipped with a crosswind opening, and the crosswind opening is communicated with the purifying chamber through a pipeline. A pair of separator plates is symmetrically arranged on the lower portion of the hearth. The separator plates, the sidewall of the oven body and the bottom end face of the oven body are connected together to form an air inlet chamber. The air inlet chamber is communicated with an air inlet end. The first electrical heating tube is positioned between the filter plates and the separator plates. The air evening plate is fixedly arranged between the first electrical heating tube and the separator plates. The circulating blower fan, the second electrical heating tube, the catalysis combustor and the heat exchanger are successively arranged in the exhaust channel. The enamelled wire oven fully utilizes heat energy, enables the loss of electric energy to be reduced, and is energy-saving and environment-friendly.

Description

Technical field: [0001] The invention relates to the technical field of enameled wire production equipment, in particular to an enameled wire oven. Background technique: [0002] The enameled wire oven is used to heat and cure the paint on the outer layer of the wire to form a paint film during the production process. The principle is that the painted wire is baked in the furnace to form an insulated wire. During the baking process of the enameled wire, the solvent vapor and cracked low-molecular substances generated by the enameled wire in the oven must be discharged from the furnace in time. The density of the solvent vapor and the humidity in the gas will affect the solvent evaporation during the baking process and affect the curing of the paint film. The cracked low-molecular substances will affect the smoothness and brightness of the paint film. The temperature of the solvent vapor that needs to be discharged is usually above 400°C. When exhaust gas is discharged, a la...

AI Technical Summary

Problems solved by technology

The temperature of the solvent vapor that needs to be discharged is usually above 400°C, and a large amount of heat energy is discharged at the same time as the exhaust gas is discharged, resulting in a large amount of heat loss, thereby increasing energy loss, and at the same time causing pollution to the atmospheric environment and destroying the ecological environment.
