Problems solved by technology

The traditional motor fan has its advantages and many disadvantages, such as: heavy weight, large volume, high power consumption, high noise, poor explosion-proof and anti-static performance, this kind of fan is not suitable for use in coal mines, subway projects, and tunnels. It is easy to cause safety accidents, so it is an urgent problem to be solved in the current production to develop light, durable, antistatic and flame retardant fans suitable for coal mines, subways, and tunnels

Abstract

The invention provides a light fan adaptable to high-risk environments, such as mines, tunnels, metros and the like. The light fan comprises a shell body, wherein the shell body is provided with an air inlet and an air outlet; the shell body is provided with a wind wheel shaft, a bearing, and a wind wheel fixed on the bearing; both the blades of the wind wheel and the shell body are made of polymer material layers; the fan is driven by a hydraulic motor; and the wind wheel shaft is connected with a power output shaft of the hydraulic motor. The light fan can work by utilizing the hydraulic system widely used in the work areas, such as mines, tunnels, metro engineering and the like, does not need a power supply, is safe and reliable, and is adaptable to the adverse and dangerous work environments, such as mines, tunnels, metro engineering and the like; moreover, the light fan is light in weight, suitable for the mining machinery, such as a heading machine, and used as an air inhaler of a dust catcher on-site; and the shell body and the blades have the characteristics of electrostatic resistance, flame resistance, high strength, shock resistance, aging resistance, acid-base resistance, stable texture and the like. The light fan can meet the requirements of anti-explosion, anti-static electricity and flame resistance.

Description

technical field [0001] The invention relates to a light fan, in particular to a fan used in mines, petroleum fields or other dangerous occasions. Background technique [0002] With the continuous improvement of the mechanization and automation of coal mines, subways, and tunnels, the dust content in the air in the roadways has risen sharply, seriously threatening the safety of coal mines, subway projects, and tunnels, as well as the health of workers. The current ordinary fans are made of metal shells and powered by motors. The traditional motor fan has its advantages and many disadvantages, such as: heavy weight, large volume, high power consumption, high noise, poor explosion-proof and anti-static performance, this kind of fan is not suitable for use in coal mines, subway projects, and tunnels. It is easy to cause safety accidents, so it is an urgent problem to be solved in current production to develop light, durable, antistatic and flame retardant fans suitable for coal...
