Large-scale desulphurization stirring paddle

Abstract

The invention relates to a detachable large desulphurization stirring paddle with an anticorrosion structure. According to the technical scheme provided by the invention, the large-scale desulphurization stirring paddle comprises a mixer shaft, a wheel hub and stirring blades and is characterized in that the wheel hub contains a wheel hub spindle sleeve; the mixer shaft is fixed inside the wheel hub spindle sleeve; several short wheel hub blades are uniformly distributed on the periphery of the wheel hub spindle sleeve in the circumferential direction; installing holes are drilled on the short wheel hub blades; a wrapping layer is arranged on the surface of the mixer shaft, the wheel hub spindle sleeve and the short wheel hub blades; Installing holes are also drilled on the stirring blades and a wrapping layer is individually arranged on the surface of the stirring blades; and the stirring blades are fixedly connected with the short wheel hub blades by bolts which pass through the installing holes. The stirring blades have a detachable structure, thus bringing great convenience for transportation and installation and broadening the types of desulphurization stirring paddles. In addition, the type of the stirrer with more than two blades on one single layer is fully applied.

Description

technical field [0001] The invention relates to a large-scale desulfurization stirring paddle with an anti-corrosion structure and a detachable assembly applied to a large-scale desulfurization stirring tank. Background technique [0002] In recent years, with the implementation of the country's active macro-control policies and environmental protection regulations, the flue gas desulfurization industry in domestic thermal power plants has developed rapidly, and desulfurization equipment has gradually developed towards large-scale development. For example, the volume of desulfurization mixing tanks has continued to increase. Correspondingly, The diameter of the stirring blade is also continuously increasing, and the stirring blade used in the desulfurization stirring tank usually needs anti-corrosion treatment to increase its service life. The current conventional anti-corrosion treatment is to weld the stirring paddle to the shaft and then line the whole with rubber. For sm...

AI Technical Summary

Problems solved by technology

The current conventional anti-corrosion treatment is to weld the stirring paddle to the shaft and then line the whole with rubber. For small stirring paddles, its transportation and installation are relatively easy, but for large stirring paddles, due to the overall rubber lining and bulky, Its transportation and installation are difficult, and it is easy to cause damage to the rubber during the transportation and installation process.
