Abstract
The utility model relates to a novel highly effective stirrer, which is designed for a deep tank. According to the technical scheme provided by the utility model, the stirrer for the deep tank comprises a hub and paddles, and is characterized in that the hub comprises a hub shaft sleeve, wherein the hub shaft sleeve is used for fixedly installing a stirring shaft; a plurality of hub short blades which are uniformly distributed along the periphery are integrally arranged at the outer periphery of the hub shaft sleeve; and the paddles are fixedly connected to the hub short blades. The paddles provided by the utility model are set into variable section circular arcs, the flow generated by the paddles is axial flow, and high flow can be obtained under lower power; the paddles of the stirrer are arc and lighter in weight, so design requirement of a longer shaft can be met; and after the stirrer is adopted, the rotation speed of the stirrer can be improved, so the diameter of the stirrer can be reduced on the premise that the stirring efficiency does not reduce, the required circulation flow can be achieved at the same time, and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to a kind of dark jar of new and effective agitator that application designs that be.
Background technology
Mixing operation is the generally operation in the industrial processes, and improve stirrer efficiency is to stir the target that industry is pursued always.In existing dark jar, longer because of shaft, the shaft that causes for fear of running in critical speed range shakes and lost efficacy, and agitator needs running under slow speed usually.And in order to obtain required circular flow, under slow-speed of revolution situation, stirrer diameter must increase, and has so just increased the weight and the cost of agitator.And when common high-efficiency axial flow stirrer diameter ratio surpass tank body 50% the time, the high efficiency agitator just loses original meaning efficiently.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of new and effective agitator that is applied on dark jar is provided, and it can obtain bigger flow under less power, satisfy the designing requirement than major axis, reduces the manufacturing cost of agitator.
The technical scheme that provides according to the utility model; Dark jar is used agitator; Comprise wheel hub and blade, it is characterized in that: said wheel hub comprises the wheel hub axle sleeve, and the hub spindle cover is used to fixedly mount shaft; Be wholely set the wheel hub paddle that some edges circumferentially are uniformly distributed with in wheel hub axle sleeve periphery, said blade is fastened on the wheel hub paddle.
As the further improvement of the utility model, said wheel hub paddle inclination is fixed on hub spindle and puts, and the cross section of wheel hub paddle is a circular arc; Said blade is obliquely installed equally, and the cross section of blade also is a circular arc, and the crooked radian of blade is identical with the crooked radian of wheel hub paddle.
As the further improvement of the utility model, a side of said blade is the straight line side, and another side is a curvilinear, and the width of blade is increased gradually earlier by its blade root to end of blade and reduces gradually.
As the further improvement of the utility model, said blade is suppressed or is rolled by flat board and forms.
As the further improvement of the utility model, said wheel hub paddle has three, also has three with the blade of the corresponding connection of wheel hub paddle.
The utility model compared with prior art, advantage is: the blade of (1) the utility model is set to variable cross-section circular arc, flowing that this blade produces is axial flow, can under less power, obtain bigger flow; (2) because the blade of agitator is circular arc type, weight is lighter, can satisfy the designing requirement than major axis; (3) behind employing the utility model, the rotating speed of agitator can improve, thereby can under the prerequisite of not losing stirring efficiency, reduce the diameter of agitator, can reach required circular flow equally, thereby reduce the manufacturing cost of agitator.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: said dark jar mainly comprises wheel hub 1 and blade 2 two parts with agitator; Said wheel hub 1 comprises wheel hub axle sleeve 1a; Wheel hub axle sleeve 1a is used for through flat key fixed installation shaft; Be wholely set the wheel hub paddle 1b that three edges circumferentially are uniformly distributed with in wheel hub axle sleeve 1a periphery, said blade 2 is fastened on the wheel hub paddle 1b through bolt part.
Like Fig. 1, shown in Figure 2, said wheel hub paddle 1b tilts to be fixed on the wheel hub axle sleeve 1a, and the cross section of wheel hub paddle 1b is a circular arc; Said blade 2 is obliquely installed equally, and blade 2 is suppressed or rolled by flat board and forms, and the cross section of blade 2 also is a circular arc, and the crooked radian of blade 2 is identical with the crooked radian of wheel hub paddle 1b.A side of said blade 2 is the straight line side, and another side is a curvilinear, and the width of blade 2 is increased gradually earlier by its blade root to end of blade and reduces gradually.
The blade 2 of the utility model is set to variable cross-section circular arc, can reduce fluid resistance, makes agitator have higher discharging performance, can under less power, obtain bigger flow, is applicable to the mixing between each phase materials.
Because the blade 2 of agitator is circular arc type, has increased the structural strength of blade 2, can adopt thin blade 2 thickness; Alleviated the weight of agitator; Can satisfy designing requirement on the one hand, make agitator critical speed be improved on the other hand, thereby can under the prerequisite of not losing stirring efficiency, reduce the diameter of agitator than major axis; Can reach required circular flow equally, thereby reduce the manufacturing cost of agitator.
