AI Technical Summary

Problems solved by technology

This kind of processing technology is complex, time-consuming and labor-intensive. The impeller produced has high resistance and poor efficiency, and often falls off due to screw corrosion or aging of the adhesive, causing the blades to separate and causing the equipment to fail to operate normally.

Embodiment Construction

[0009] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] figure 1 shows a perspective view of the impeller in the present invention, figure 2 yes figure 1 Section A-A of the impeller shown.

[0011] Such as Figure 1-2 As shown, the impeller includes an inner disc 2, an outer disc 4 and a blade 1; the bottom of the inner disc 2 has a rib 3, and the outer disc 4 has a wind tunnel; the blade 1 is arranged on the Between the inner disc 2 and the outer disc 4.

[0012] The inner disc 2, the outer disc 4 and the blade 1 are integrally formed by hot pressing through a mold.

[0013] Preferably, said impeller is made of plastic.

[0014] Since the impeller is integrally formed by hot pressing, it avoids the disadvantages of complex processing technology, time-consuming, laborious, high resistance and poor efficiency when forming by screw assembly, bonding, riveting, welding, etc. , At the ...

Abstract

The invention relates to an integrated corrosion resisting impeller, which comprises an inner wheel disc (2), an outer wheel disc (4) and a blade (1); the blade (1) is arranged between the inner wheel disc (2) and the outer wheel disc (4), and the integrated corrosion resisting impeller is characterized in that the inner wheel disc (2), the outer wheel disc (4) and the blade (1) are formed by a corrosion resisting material integrally. As the blade is integrally formed by hot pressing, the defects of complicated processing technology, time and labor waste, large resistance of the produced impeller and inefficiency when being formed in the ways of screw assembly, bonding, riveting, welding and the like are avoided, and the failure of abnormal equipment operation caused by blade separation owning to falling off of the corroded screw or aged bonder can also be avoided.

Description

technical field [0001] The invention relates to an anti-corrosion impeller, in particular to an integrated anti-corrosion impeller. Background technique [0002] Traditionally, impellers used in the chemical industry are made of metal. Since the gas or liquid in the chemical industry is acidic or alkaline, when using a metal impeller, although casting the impeller with a metal material can meet its rigidity requirements, in some highly corrosive and easy-to-wear industries such as chemical industry, mineral processing, etc. etc. During use, the impeller is easy to shorten the working life due to corrosion and wear, so it needs to be replaced frequently, which affects work efficiency and increases production costs. Although some time wheels are made of corrosion-resistant and wear-resistant metal materials, their manufacturing process requires High, the production cost is large, and it can only be used in a few special industries, which cannot meet the market promotion and a...
