Axial flow fan for tunnel brick kiln

Abstract

The invention provides an axial flow fan for a tunnel brick kiln. The axial flow fan comprises a mounting base, and a fixing frame is arranged on the mounting base; a fan air cylinder is fixedly installed on the fixing frame, wherein a main shaft bearing sleeve pipe is fixedly arranged in the fan air cylinder through multiple connecting rods, and the main shaft bearing sleeve is connected with a fan main shaft through a bearing; the fan main shaft is fixedly connected with fan blades through a fan blade fixing device; the fan main shaft is further connected with an axial flow motor through a gear transmission mechanism, the axial flow motor is arranged at the inner part of a heat insulation frame, and the axial flow motor main shaft penetrates through the front end of the heat insulation frame; and an emergency refrigeration device is arranged in the heat insulation frame. According to the axial flow fan, the axial flow motor is arranged in the heat insulation frame, the emergency refrigeration device is further arranged in the heat insulation frame, so that when the infrared temperature measuring instrument detects that the temperature in the heat insulation frame is not suitablefor working of the axial flow motor, the emergency refrigeration device is started, and therefore high-temperature hot air in the heat insulation frame is taken away, and the working temperature of the axial flow motor is ensured.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an axial flow fan for a tunnel brick kiln. Background technique [0002] The tunnel-type brick kiln is a tunnel-type brick kiln that uses coal gangue and shale as the main raw materials to heat wet bricks and fire them into finished bricks. When the tunnel brick kiln is working, the axial flow fan is an indispensable part, and the current tunnel brick kiln generally High temperature resistant axial flow fans are selected, and high temperature resistant axial flow fans are processed and formed with high temperature resistant metal materials, resulting in high cost of high temperature resistant axial flow fans, and the cost of the tunnel brick kiln itself and the price of bricks on the market have made it impossible for many brick factories to Bear high-priced auxiliary equipment, and choose ordinary axial flow fans to work, so as to choose intermittent work to reduce the pressure of ...

[0002] The tunnel-type brick kiln is a tunnel-type brick kiln that uses coal gangue and shale as the main raw materials to heat wet bricks and fire them into finished bricks. When the tunnel brick kiln is working, the axial flow fan is an indispensable part, and the current tunnel brick kiln generally High temperature resistant axial flow fans are selected, and high temperature resistant axial flow fans are processed and formed with high temperature resistant metal materials, resulting in high cost of high temperature resistant axial flow fans, and the cost of the tunnel brick kiln itself and the price of bricks on the market have made it impossible for many brick factories to Bear high-priced auxiliary equipment, and choose ordinary axial flow fans to work, so as to choose intermittent work to reduce the pressure of axial flow fans, but intermittent work also reduces the production efficiency of bricks, and even intermittent work due to the brick kiln Working at high temperature, it is still easy to burn the motor
