Description

Technical Field

[0001] This utility model relates to the field of industrial electric furnace technology, and in particular to a hot air stirring device for industrial electric furnaces that is easy to disassemble and maintain. Background Technology

[0002] The hot air stirring device in an industrial electric furnace is directly related to the uniformity of the furnace temperature and the quality of the heat-treated workpieces. Existing systems use motors to drive the fan blades inside the furnace to achieve hot air stirring and circulation. The motors are mounted on motor mounts, and existing motor mounts all use a closed structure, which results in relatively poor heat dissipation.

[0003] Moreover, the existing hot air stirring device has a fixed structure, and it is usually directly fixed on the electric furnace. Once a fault or abnormality occurs, it needs to be completely disassembled and repaired. If it cannot be repaired, it needs to be replaced as a whole, which is inconvenient to install and disassemble and is costly. Utility Model Content

[0010] In the aforementioned hot air stirring device for industrial electric furnaces that is easy to disassemble and maintain, the heat insulation layer is Z-shaped, and the electric furnace and the mounting base are respectively provided with grooves for accommodating the heat insulation layer.

[0011] Compared with the prior art, this application includes a detachable mounting base on the electric furnace, and a blower is detachably mounted on the mounting base. The blower itself consists of a detachable connecting seat, a housing, a motor, a shaft, and stirring blades. The electric furnace is provided with a mounting groove corresponding to the mounting base, and the width of the mounting groove corresponds to the diameter of the stirring blades.
