Abstract

The invention discloses a high temperature fan which needs no passing water and can effectively prolong the bearing service life, which comprises a motor mounted on a support, the support is fixed on the inner side of a mounting panel, the inner side of the mounting panel is also provided with a mounting seat, the motor drives a main shaft through a drive device, the main shaft is support in the mounting seat through a pair of bearings, and another end of the main shaft passes through the mounting panel and is provided with an impeller. an air inlet is disposed on the external side of the impeller and is fixed on the mounting panel through a sleeve, the outside of the mounting panel is also provided with a thermal insulation layer; the main shaft in the mounting seat is also provided with a strong cooling fan blade, and the side wall of the mounting seat is provided with an air vent. The invention is suitable for multiple industry heat treatment furnaces.

Description

technical field [0001] The invention relates to a high-temperature fan used in an industrial heat treatment furnace. Background technique [0002] The common high-temperature fans in China are composed of the following structural parts: air inlet, impeller, heat insulation box, main shaft, cooling blades, water-cooled bearing housing, motor and motor support frame. Because the working temperature of the high-temperature fan is relatively high, it is generally between 650°C and 800°C. Therefore, its working principle is: the impeller rotates at high speed in a high temperature environment; the heat insulation box blocks part of the heat conduction to ensure that the temperature on the panel of the box is lower than 40°C; the main shaft is equipped with air cooling and the bearing seat is equipped with water cooling for cooling Bearings to prevent damage to bearings due to excessive heat; an air inlet is set in the heat treatment furnace as a wind guide. However, installing ...
