High-temperature-resistant axial flow fan

Abstract

The invention discloses a high-temperature-resistant axial flow fan which structurally comprises a motor supporting base, a driving motor, a fan shell, a connecting shaft, rotating fan blades, an airinlet and a rapid net disassembly pressurizing reinforcement device. The top of the motor supporting base is connected with the bottom of the driving motor in an electric welding mode, the driving motor is mounted at the rear end of the fan shell, the inner side of the fan shell is nested with the connecting shaft, the outer side of the driving motor and the connecting shaft are nested and positioned on the same central line, the rotating fan blades are mounted at the rear end of the connecting shaft, the rotating fan blades and the connecting shaft are positioned on the same central line, thedriving motor is arranged at the rear ends of the rotating fan blades, and the driving motor and the rotating fan blades are positioned on the same axis. When the high-temperature-resistant axial flow fan is mounted in a kitchen and used for ventilation, an outlet of a ventilation port can be adjusted by self-rotation, and too slow gas ventilation caused by low wind pressure is avoided. Moreover,when a filter screen of the high-temperature-resistant axial flow fan needs to be cleaned, a fixing fastener is opened, the filter screen can be easily taken out by turning the shell, and complexityof a removal process is prevented.

Description

technical field [0001] The invention relates to the field of fans, more precisely, it relates to a high temperature resistant axial flow fan. Background technique [0002] The axial flow fan is that the gas flows parallel to the fan shaft and the gas flows parallel to the fan shaft. It is mainly installed in kitchens and construction sites, and is easy to install. However, the current high temperature resistant axial fan has the following disadvantages: [0003] 1. When the high-temperature-resistant axial flow fan is installed in the kitchen for ventilation, due to the low wind pressure, the gas flow is slow, resulting in a poor environment in the kitchen. [0004] 2. The high-temperature-resistant axial flow fan is used in the kitchen. When the ventilation is used, many oil molecules adhere to the filter screen. When it needs to be cleaned, the removal process is cumbersome. Contents of the invention [0005] Aiming at the deficiencies in the prior art, the purpose of ...

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a high temperature resistant axial flow fan to solve the problem that the high temperature resistant axial flow fan in the prior art is installed in the kitchen for ventilation and ventilation, due to the small wind pressure, the gas The flow is slow, resulting in a poor environment in the kitchen, and the high temperature resistant axial flow fan is used in the kitchen. When using the ventilation, many oil molecules adhere to the filter screen. When it needs to be cleaned, the removal process is cumbersome.
