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...

Examples

Embodiment Construction

[0037] Now in conjunction with accompanying drawing, the present invention will be further described:

[0038] As shown in the figure, a multi-protection industrial fan includes:

[0039] Chassis 3;

[0040] A boom 2, one end of which is fixed to the top of the cabinet 3, and the other end is fixed to the suspension beam 1;

[0041] Motor 41, the housing of which is fixed in the casing 3;

[0042] Gear box 42, its input shaft is fixed with motor 41 main shaft;

[0043] Chassis 6, which is fixed on the output shaft of reduction box 42 by chassis bolt 7;

[0044] Blade 5, multi-piece, it is evenly fixed on the chassis 6;

[0045] Also includes:

[0046] Rotate the insurance ring 88, which is fixed on the top of the chassis 6 by a plurality of first bolts 85;

[0047] Fixed safety ring 87, it is fixed on the bottom of cabinet 3 by a plurality of second bolts, the inner ring of fixed safety ring 87 is smaller than the outer ring of rotation safety ring 88, and is positioned ...
