Problems solved by technology

[0002] In the current enameled wire production, hot air circulation is usually used for heat circulation treatment in the enameled wire baking step. Therefore, a heat circulation structure is usually provided in the oven part. The conventional hot air circulation is to let the hot air in the oven enter into the After the reaction in the catalytic device, it is heated, and then the hot air is sucked out by the fan and sent back to the oven; in this process, the temperature of the hot air before the oven enters the catalytic device is about 400°C, and the ga

Example Embodiment

[0012] Embodiment 1: Enameled wire baking hot air circulation method, the hot air in the oven 1 is sucked out by the fan 2 installed in the front of the oven 1, and the fan 2 sends the hot air containing solvent vapor into the catalytic device 3, and passes through the fan 2. The hot air from the catalytic device 3 enters the combustion chamber 4 for heating, and the heated hot air enters the heat storage chamber 5, and the hot air is sent from the rear of the oven 1 through the heat storage chamber 5, and the heat storage chamber 5 The middle part of the hot air enters the heat exchange device 10 and is discharged after heat exchange. The heat exchange device 10 heats the sucked air and sends it to the front end of the oven 1 .

[0013] The hot air circulation device for enameled wire baking as shown in Figure 1 is composed of an oven 1. A fan 2 is provided on the air supply pipe 7 at the front of the oven 1. The fan 2 is connected to the catalytic device 3 through the air sup...

Abstract

This invention relates to a circulating method and a device for hot air baking enamel wires, in which, a fan in front of the baker aspirates hot air in the baker and sends it into a catalyzing device, which sends the hot air to a firebox for heating then the hot air enters into a heat-storage chamber and then is sent to the baker from the back of the baker, which applies a fan to send hot air into a circulation device and then to a baker, since temperature of hot air entering into the fan is low, requirement on the vanes and air vent is low and speed of the hot air entering into the baker is uniform, the thermal circulation result is good.

Description

technical field [0001] The invention relates to a method and a device for circulating heat, in particular to a method and a device for circulating hot air for enameled wire baking. Background technique [0002] In the current enameled wire production, hot air circulation is usually used for heat circulation treatment in the enameled wire baking step. Therefore, a heat circulation structure is usually installed in the oven part. The conventional hot air circulation is to let the hot air in the oven enter into the After the reaction in the catalytic device, it is heated, and then the hot air is sucked out by the fan and sent back to the oven; in this process, the temperature of the hot air before the oven enters the catalytic device is about 400 ℃, and the gas after catalytic combustion The temperature will reach about 600 ℃, and the fan blades and tuyere of the fan must be used at such a high temperature, and the material requirements are very high, and the service life is no...
