Problems solved by technology

Before the enameled rectangular wire enters the oven to cure the paint film, it needs to go through a period of low-temperature baking in the preheating evaporation zone. The existing rectangular wire enamelling machine oven usually adopts a single electric heating tube heating method in the preheating evaporation zone. , this kind of brush baking method that completely relies on electric heating tube preheating greatly increases the power consumption cost of rectangular enameled wire production

Abstract

Provided is a device for heating the preheat evaporation area of a rectangular wire enameling machine oven by the utilization of exhaust gas waste heat. The device comprises a hearth, wherein the hearth comprises the preheat evaporation area at the lower portion and a solidification area at the upper portion; a hearth inlet is formed in the bottom of the preheat evaporation area; one side of the hearth is connected with an inlet pipeline of a main circulating fan; an outlet of the main circulating fan is connected with a pipeline of a heat exchanger; the other end of the heat exchanger is connected with a circulating cavity; a suction inlet of a waste discharge fan is connected with the heat exchanger; an exhaust gas circulating pipeline is arranged between the circulating cavity and the heat exchanger; an outlet of the waste discharge fan is connected with the lower portion of the preheat evaporation area through a pipeline; the top side face of the preheat evaporation area is connected with a waste discharge pipeline. The device can cyclically utilize exhaust gas generated by baking enameled wires to heat the preheat evaporation area, then reduces the energy consumption of the preheat evaporation area, saves energy and is environmentally friendly.

Description

technical field [0001] The invention relates to enameled wire manufacturing equipment, in particular to a device for heating the preheating evaporation zone of a medium-rectangular wire enameled machine oven by using exhaust gas waste heat. Background technique [0002] The enameled wire oven is used to bake the painted copper wire, so that the paint on the outer layer of the copper wire is heated and cured into a paint film, thereby forming an insulated wire. Before the enameled rectangular wire enters the oven to cure the paint film, it needs to go through a period of low-temperature baking in the preheating evaporation zone. The existing rectangular wire enamelling machine oven usually adopts a single electric heating tube heating method in the preheating evaporation zone. , this kind of brush baking method that completely relies on electric heating tube preheating greatly increases the power consumption cost of rectangular enameled wire production.
