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.

Embodiment Construction

[0013] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0014] As shown in the figure: the large desulfurization stirring impeller is mainly composed of three parts: the stirring shaft 1, the hub 2 and the stirring blade 3. The hub 2 includes the hub bushing 2a, and the stirring shaft 1 is welded and fixed on the hub bushing 2a Inside, four short hub paddles 2b uniformly distributed in the circumferential direction are integrally arranged on the periphery of the hub sleeve 2a, and mounting holes are drilled on the hub short paddles 2b. The stirring shaft 1, the hub sleeve 2a and the short hub paddles The surface of 2b is lined with an integrated rubber coating layer 5; the stirring blade 3 is also drilled with a mounting hole, and the surface of the stirring blade 3 is lined with a rubber coating layer 5; the stirring blade 3 and the hub short paddle The leaves 2b are attached and secured by bolt members 6 passing t...

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...
