Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as Figure 1-3, the utility model provides a kind of novel axial stream blade, comprise blade 1, described blade 1 is made up of leaf hub 11, linear leaf 12 and short blade 13, described linear leaf 12 and short blade 13 are all welded on leaf hub 11, and described linear leaf 12 is mounted by means of bolts on the below of short blade 13; The bottom of described blade 1 is provided with shaft 2, and described shaft 2 is connected with the shaft coupling 4 in frame 3, and described shaft coupling 4 is connected with the output shaft of motor reducer 5.
Described blade 1 radially width reduces gradually, and the end that rotating speed is the highest is comparatively thin, and the root that rotating speed is lower is wider, and flow velocity in the whole radial extension of blade 1 is kept in balance.
Described blade 1 is radially distortion gradually from center, thus avoids producing turbulent flow in whipping process.
Two limits of described blade 1 process section oblique angle respectively, reduce the resistance stirred, and reduce material to the erosion of blade.
Described linear leaf 12 and short blade 13 have arcuate structure, utilize little inclination angle directing material to produce axial flow, ensure that enough stirring flows produce.
Described blade 1 liang of long limit profile angle 20 ° ~ 60 °; Described blade 1 liang of long limit and horizontal plane angle 5 ° ~ 8 °.
The A point of described blade 1 end and the B point of root are apart from elevation of water ratio 1: 2 ~ 1: 3; The C point of described blade 1 end and the D point width ratio 1: 2 ~ 1: 3 of root.
Blade of the present utility model is blade of variable cross-section, the inclination angle of blade and the width of blade change with its radial position, and impeller blade is made by steel plate is bending according to certain rules, need not use the moulding process such as milling or precision pouring, be fixed by bolts on wheel hub, be easy to be assembled into relatively large impeller.This design feature close to uniform pitch change blade angle of Axial flow impeller leaf impeller can provide larger flow and less shear action, and the blade-section near wheel hub is assigned to compared with blade tip, and blade angle is steeper, and width of blade is wider.From wheel hub to end of blade, blade angle reduces gradually, and leaf is wide to narrow gradually.Therefore, impeller is along each point on length of blade close to uniform pitch, and the flow velocity that whole discharge opeing face produces is almost uniform.Therefore, Axial flow impeller leaf impeller-agitator is particularly suitable for the use of mechanical mixture agitator.
This blade can use very little energy, produces axial eddy, reaches the object stirred.Blade adopts fluid mechanics principle design, by increasing flow velocity, reducing turbulent flow and reaching energy-conservation effect with shearing.Axial flow impeller leaf is farthest converted into pure axial flow available energy, and blade occurs without movement disorder; Rational in infrastructure, especially mixer supports relatively less, meets the convenience of installation and maintenance, the mixing effect that the main shaft linearity that mixer is high has simultaneously met and stirring stability, and then enhances productivity, and reduces maintenance cost.
Feature that this propeller-blade is safeguarded less with it, flexible operation, less loss in head, mixing intensity are easily controlled, efficiency is high, shearing force is almost nil etc. and use more.Because of its simple structure, without the need to other power-equipments except motor reducer, operational management is convenient and apply more.Mixer supports relatively less, meet the convenience of installation and maintenance, the simultaneously mixer mixing effect that requires high main shaft linearity to meet and stirring stability, this Axial flow impeller leaf is applicable to the mixing of middle thinlyfluid, heat transfer, circulation, particle suspends, dissolve, be widely used in pharmacy, chemical industry, sewage disposal, environmental protection, desulfurization, water-coal-slurry and oil and foodstuffs industry, possesses good application, its advantage: low sheraing, strong circulation, low energy consumption, blade is detachable, can use in large-scale tank diameter, middle and slow speed of revolution runs, low energy consumption and low manufacturing cost is possessed compared with existing product, be easy to maintenance and the maintenance of equipment, motor reducer of its conventional configuration has R series Hardened gear face and bevel gear K series, and this model reductor possesses the advantages such as the high and noise of operational efficiency is low, is also the type that current market is promoted mainly.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
