Problems solved by technology

[0005] At present, the impellers of wet dust suppression fans at home and abroad mostly adopt the form of radial straight blades. The radial straight blade wet dust collector has been introduced into my country for 10 years and has achieved good results in many industries, but it is still in use. There are some problems, the main reason is that the impeller is welded by multiple cold stamping parts, and the dynamic balance and installation positioning problems are difficult to guarantee. The fan blades of this structure have been in operation for a long time, and the blades are easy to deform. , the noise is large, it will cause noise pollution to the surrounding staff and the mechanical life is short, it is difficult to capture large particles of dust, and the dust reduction efficiency is low

Embodiment Construction

[0016] The present invention or the invention will be further explained by specific examples below.

[0017] Such as figure 1 As shown, a wet-type dust suppression fan impeller, including a hub, is characterized in that: blades are evenly distributed around the outer cylindrical surface of the hub, the hub and the blades are of an integrated structure, and the material of the hub and the blades is aluminum alloy. The forming method of the hub and the blade is die casting. Such as figure 2 As shown, the hub is a thin-walled hollow structure, which reduces materials and saves costs. It includes an annular fan blade connection area and an annular shaft connection area. The shaft connection area is drilled with a central hole and milled with a keyway for easy connection with the shaft. . The blades are twisted blades with a twist angle of 5° to 10°, and the thickness is uneven. The overall characteristics are thick in the middle, thin at the edges, thick at the root, and thin ...

Abstract

The invention relates to a wet-type dust falling fan impeller. The fan impeller comprises a wheel hub (1), and is characterized in that blades (2) are uniformly distributed on the periphery of the outer cylindrical surface of the wheel hub, the wheel hub and the blades are of an integrated structure, the wheel hub and the blades are made of aluminum alloy materials, and the wheel hub and the blades are formed in a pressure casting mode. The wet-type dust falling fan impeller has the advantages of being light in weight, resistant to corrosion, stable and compact in structure, good in pneumaticperformance and high in dust falling efficiency.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an impeller of a wet dust suppression fan. Background technique [0002] In recent years, my country's industrialization level has made considerable progress, but the increasingly prominent problem of dust pollution cannot be ignored. Production dust formed in the process of industrial production can be suspended in the air for a long time, reducing visibility and even causing extreme weather such as smog, which not only directly endangers the health of the respiratory system but also indirectly causes various diseases as a carrier of germs. As the most important and common occupational disease, pneumoconiosis is caused by long-term inhalation of productive dust. At present, my country has become the country with the largest number of pneumoconiosis patients in the world, and more than ten million workers are exposed to productive dust, mainly concentrated in cement, coal mines, st...
