Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0028] Such as Figure 1-7 As shown, an industrial fan includes several fan blades 1, a wheel disc 2, a geared motor 3, a frame 4, a boom 5 and a housing 6, and the fan blade 1 is fixed to the wheel disc 2 through a blade handle 11. The reduction motor 3 drives the wheel disc 2 to rotate to drive the fan blade 1 to rotate. The frame 4 includes a portal frame 41 and a flange 42. The flange 42 is fixed below the portal frame 41. The center of the flange 42 is To the middle position of the upper beam of the door frame 41; the geared motor 3 is fixed to the flange 42, and a rotating shaft is set in the center of the flange 42 to perforate; the boom 5 is connected and fixed to the upper beam of the door frame 41;

[0029] Such as image 3 As shown, the fan blade 1 includes upper and lower layers (the upper and lower layers are distinguished accor...

Abstract

The invention relates to an industrial fan, comprising a plurality of fan blades, a wheel disc, a deceleration motor, a frame and a hanger rod. The fan blade includes upper and lower layers, which are formed by bending at one time, wherein there is a gap between the upper and lower layers. ; The fan blade and the stalk are connected by a connecting piece; the connecting piece is formed with two concentric bushings, left and right, which are arranged at intervals, and a special-shaped piece is embedded in the two bushings, and a special-shaped piece is embedded on the special-shaped piece. The vibration isolation rubber sleeve is sleeved, so that the outer wall of the special-shaped part and the inner wall of the shaft sleeve are separated by the vibration isolation rubber sleeve; the leaf stalk is inserted between the two concentric shaft sleeves, and is connected with the connecting parts; the flange plate under the frame An anti-falling ring is hung on the upper sleeve; the inner diameter of the anti-falling ring is smaller than the outer diameter of the flange, and the outer diameter is larger than the outer diameter of the flange; the anti-falling circle is connected with the fan blade shank. The invention has wide wind coverage, low energy efficiency, long service life and low working noise, and can effectively prevent the fan blades from falling.

Description

technical field [0001] The invention relates to an industrial fan. Background technique [0002] Industrial fans are widely used in high and large spaces such as industrial plants, logistics storage, waiting rooms, exhibition halls, supermarkets, etc., as the preferred solution for space ventilation and personnel cooling. The comfort brought by the super-large energy-saving fan is unmatched by other fans. Under the super-large energy-saving fan, you will feel the three-dimensional air supply from all directions, so as to cover the entire body and maximize the sweat evaporation surface, thereby Form a breeze system that resembles nature. [0003] The quality of a fan is mainly considered from the aspects of wind coverage, energy consumption, noise level, service life and safety. However, it is difficult for current fans to gather all or most of the advantages, and the market for high-performance fans is still lacking. . Contents of the invention [0004] The purpose of t...
