In-hearth motor mounting structure capable of slowing down heat transfer

Abstract

An in-hearth motor mounting structure capable of slowing down heat transfer comprises a hearth. A heating duct is arranged in the hearth. A motor body is mounted on the outer surface of the hearth. Thermal insulation mounting feet are mounted below the motor body. The thermal insulation mounting feet are firmly mounted on the hearth through fixing bolts. A retaining plate is further disposed between the thermal insulation mounting feet and the outer surface of the hearth. Positions, corresponding to the fixing bolts, of the retaining plate are provided with bolt holes. The rotary shaft of the motor body extends deeply into the heating duct of the hearth and penetrates the retaining plate and the hearth. A thermal insulation sleeve is disposed at the position, where the rotary shaft penetrates the retaining plate, of the retaining plate. A rectangular ventilation groove for blocking heat transfer is formed around inner wall of the thermal insulation sleeve. The in-hearth motor mounting structure has the advantages that the distance between the motor body and the hearth is increased by the thermal insulation mounting feed, and heat transfer is slowed down; motor operation is guaranteed by the thermal insulation sleeve with the rectangular ventilation groove, and the heat of the hearth can be prevented from being transferred to the outside at the rotary shaft of the motor body by the annular air flow of the thermal insulation sleeve.

Description

technical field [0001] The invention relates to a motor installation structure in a furnace chamber capable of slowing heat transfer. Background technique [0002] The inside of the furnace of the tunnel furnace is generally arranged with a heating air duct, which is heated by a heater and circulated by a fan to improve heating efficiency; in order to facilitate maintenance, the motor of the fan is generally installed on the outer surface of the furnace; the shaft of the fan motor Go deep into the furnace heating air duct, so that the motor will be affected by the heat in the furnace, making the motor temperature too high, resulting in early damage to the motor. Contents of the invention [0003] In order to overcome the deficiencies of the prior art above, the purpose of the present invention is to provide a motor installation structure in the hearth that can slow down heat transfer, has a good heat insulation structure, and is simple in structure and easy to use.
