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
The present invention relates to a kind of being applied to and have anticorrosion structure and a removable large desulfurization paddle on the large desulfurization tank diameter.
Background technology
In recent years, along with the positive macro adjustment and control policy of country and the enforcement of environmental regulation, domestic flue gas desulphurization industry has obtained fast development; Desulphurization plant is gradually to large scale development; Volume like the desulfurization tank diameter constantly maximizes, and correspondingly, the diameter of stirring arm also constantly increases; The paddle that is used for the desulfurization tank diameter need carry out preservative treatment usually, to improve its service life.Conventional now preservative treatment is a whole again line with rubber after paddle and axle are welded; For little paddle; Its transportation, installation are also than being easier to, still for large-scale paddle, because whole line with rubber and bulky; Its transportation, installation be difficulty relatively, and in the transportation installation process, causes rubber breakage etc. easily.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art; A kind of large desulfurization paddle that is applied on the large desulfurization tank diameter is provided; It has anticorrosion structure and dismantled and assembled, is very easy to transportation and installation requirement, has satisfied the equipment anticorrosion technological requirement simultaneously.
According to technical scheme provided by the invention; The large desulfurization paddle comprises shaft, wheel hub and stirrer paddle, it is characterized in that: said wheel hub comprises the wheel hub axle sleeve; Said shaft is fixed in the wheel hub axle sleeve; Be wholely set the wheel hub paddle that some edges circumferentially are uniformly distributed with in wheel hub axle sleeve periphery, be drilled with installing hole on the wheel hub paddle, the surface of said shaft, wheel hub axle sleeve and wheel hub paddle is lined with the encapsulate layer of one; Also be drilled with installing hole on the said stirrer paddle, the surface of stirrer paddle is lined with the encapsulate layer separately; Stirrer paddle is connected fixing with the wheel hub paddle through the bolt part that passes their installing holes.
As further improvement of the present invention, fill up respectively between said bolt part two ends and stirrer paddle, the wheel hub paddle surface pressing plate is housed.
As further improvement of the present invention, said bolt part comprises screw bolt and nut, every equipped two nuts of bolt.
As further improvement of the present invention, said wheel hub paddle has four, also has four with the stirrer paddle of the corresponding connection of wheel hub paddle.
As further improvement of the present invention, said pressing plate and bolt part all adopt the two-phase stainless steel to process.
The present invention compared with prior art; Advantage is: stirrer paddle of the present invention is removable structure; Both greatly facilitated transportation and installation requirement, the pattern that has expanded the desulfurization stirring arm again makes agitator individual layer number of blade used fully greater than the oar type of two leaves.

Description of reference numerals: 1-shaft, 2-wheel hub, 2a-wheel hub axle sleeve, 2b-wheel hub paddle, 3-stirrer paddle, 4-pressing plate, 5-encapsulate layer, 6-bolt part.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the present invention is described further.
As shown in the figure: said large desulfurization paddle mainly is made up of shaft 1, wheel hub 2 and stirrer paddle 3 three parts; Said wheel hub 2 comprises wheel hub axle sleeve 2a; Said shaft 1 is weldingly fixed in the wheel hub axle sleeve 2a; Be wholely set the wheel hub paddle 2b that four edges circumferentially are uniformly distributed with in wheel hub axle sleeve 2a periphery, be drilled with installing hole on the wheel hub paddle 2b, the surface of said shaft 1, wheel hub axle sleeve 2a and wheel hub paddle 2b is lined with the encapsulate layer 5 of one; Also be drilled with installing hole on the said stirrer paddle 3, the surface of stirrer paddle 3 is lined with encapsulate layer 5 separately; Stirrer paddle 3 is connected fixing with wheel hub paddle 2b through the bolt part 6 that passes their installing holes.Installing hole on said wheel hub paddle 2b and the stirrer paddle 3 all should be drilled with before line with rubber, and the diameter of installing hole should be not less than the thickness that the diameter of bolt adds two times of encapsulate layers 5.
As shown in Figure 2, fill up respectively between said bolt part 6 two ends and stirrer paddle 3, the wheel hub paddle 2b surface pressing plate 4 is housed.Owing to be provided with pressing plate 4, with bolt part 6 when fastening, encapsulate layer 5 has received pressing plate 4 protections, is difficult for being squeezed bad, and pressing plate 4 has also stoped the encapsulate layer 5 in the installing hole to break because of stressed being extruded simultaneously, thereby installing hole is compacted, and has realized effectively fixing.All equipped two nuts of every bolt in the said bolt part 6, double nut can play locking effect, guarantees connection robust of the present invention.Said pressing plate 4 all is to adopt the two-phase stainless steel to process with bolt part 6, can satisfy requirement for anticorrosion.
