Multi-protection industrial fan

Abstract

The invention discloses a multi-protection industrial fan, which comprises a case, a hanging rod, a motor, a reduction gearbox, a chassis, multiple blades, a rotary insurance ring, a fixed insurance ring; one end of the hanging rod is fixed with the top part of the case, and the other end is fixed with a hanging beam; the shell body of the motor is fixed in the case, an input shaft of the reduction gearbox is fixed with a main shaft of the motor; the chassis is fixed on an output shaft of the reduction gearbox through a chassis bolt; multiple blades are evenly fixed on the chassis; the rotaryinsurance ring is fixed at the top part of the chassis through multiple first bolts; the fixed insurance ring is fixed at the bottom part of the case through multiple second bolts; the inner ring of the fixed insurance ring is less than the outer ring of the rotary insurance ring, and located at the lower part of the rotary insurance ring at outside of the chassis; the fixed insurance ring does not contact with the rotary insurance ring and the chassis. The multi-protection industrial fan has the beneficial effects of being simple in structure, low in cost, convenient to install, long in service life, and multiple in safety protections.

Description

technical field [0001] The invention relates to an industrial fan with multiple protections. Background technique [0002] Industrial fans are characterized by long blades, large coverage area, and easy control. In summer, when used in factories, they can blow continuously, quickly evaporate sweat on the body surface, and bring rapid and natural cooling of 5-7 degrees Celsius to workers. Keep the air dry and reduce the ambient humidity, prevent bacteria from growing, prevent equipment from rusting and mildewing; eliminate condensation, protect packaging, cartons, and pallets, and prevent moisture, corrosion, and deformation; in winter, heating sources gather on the roof, and workers on the ground cannot feel obvious As the temperature rises, in order to increase the ground temperature, the only way to increase the heating temperature is to continuously increase the heating temperature, resulting in a lot of energy waste; when the breeze of 0.2m / s is provided, the heat gath...

[0002] Industrial fans are characterized by long blades, large coverage area, and easy control. In summer, when used in factories, they can blow continuously, quickly evaporate sweat on the body surface, and bring rapid and natural cooling of 5-7 degrees Celsius to workers. Keep the air dry and reduce the ambient humidity, prevent bacteria from growing, prevent equipment from rusting and moldy; eliminate condensation, protect packaging, cartons, and pallets, and prevent moisture, corrosion, and deformation; in winter, heating sources gather on the roof, and workers on the ground cannot feel obvious As the temperature rises, in order to increase the ground temperature, the only way to increase the heating temperature is to continuously increase the heating temperature, resulting in a lot of energy waste; when the breeze of 0.2m / s is provided, the heat gathered on the roof will be absorbed by the negative pressure principle above the fan. The air is slowly pushed to the ground, so that the indoor air is fully mixed, and the ground temperature can be raised immediately. Workers can feel the warm and comfortable breeze continuously, which can save energy consumption by more than 30%. However, industrial fans cannot be equipped with protective covers, and at the same time , the leaves are longer and require good multiple protection
