Efficient energy-saving fan with low operation cost

Abstract

The invention relates to the technical field of energy-saving fans, in particular to an efficient energy-saving fan with low operation cost. The efficient energy-saving fan comprises a fan body, wherein the fan body comprises a motor, and the bottom face of the motor is fixedly connected with a machine base; the left side of the machine base is fixedly connected with a machine shell, and the left side face of the machine shell is fixedly connected with an air inlet ring; the left end of the motor is fixedly connected with an impeller; a first through groove is formed in the top face of the air inlet ring, and the side face of the first through groove is fixedly connected with a first sealing brush; a second through groove is formed in the bottom face of the air inlet ring, and the side face of the second through groove is fixedly connected with a second sealing brush; and a dust collection structure is arranged on the fan body. The fan adopts A-type transmission, is not provided with a bearing box, is higher in operation efficiency, saves electricity in use, reduces the operation cost, is smaller in size, and is wide in performance range. Meanwhile, the fan can filter air entering the machine shell, therefore guaranteeing the internal environment of the machine shell to be clean, avoiding timed cleaning and reducing the operation cost of the fan.

Description

technical field [0001] The invention relates to the technical field of energy-saving fan, in particular to a high-efficiency energy-saving fan with low operating cost. Background technique [0002] With the development of production technology, there is an urgent need to develop a medium-flow, medium-high pressure material conveying fan. The conventional national standard is used in material conveying and polishing machine selection (parameters are flow rate 20400m3 / h, total pressure 6500pa, t = 20 ℃, Atmospheric pressure Pa=11325Pa), the selected fan is such as 9-19-11.2D, with a power distribution of 75Kw and a speed of 1450rpm. Not only is the power distribution of the motor relatively large, but the D-type coupling is used for transmission, which increases the speed compared to the A-type fan transmission. The bearing box and other components, and the maximum outer diameter of the impeller has reached 1240mm, the fan occupies a large space as a whole, and the maintenance...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-efficiency and energy-saving fan with low operating cost to solve the problem of large power distribution of the motor proposed in the above-mentioned background technology. The D-type coupling is used for transmission, and the bearing box and other components are added to the A-type fan transmission. , and the maximum outer diameter of the impeller reaches 1240mm of the machine base, the overall space of the fan is large, and the maintenance is relatively complicated.
