Abstract
The utility model discloses a novel prevent laying dust fan wheel, including impeller backplate, impeller panel, main blade and supporting blade, the impeller shaft is radial, centrosymmetric transmission shape for dull and stereotyped appearance is just arranged into for main blade, main blade connects the impeller panel and welds into impeller body with the impeller backplate, the impeller panel is equipped with the air intake, and the limit connects into firm an organic whole through welding and fan axle bed in impeller backplate and the main blade, and the fan axle bed cooperates with the fan axle through the shaft hole and is connected, fan supporting blade and impeller panel, backplate, main blade all constitute triangular structure. The main and secondary blade diameter of axle centering of this neotype fan symmetry, when rotatory, the blade surface has powerful centrifugal surperficial self purification down in the effect of powerful centrifugal force to the blade high -speed, the dust can't adhere to and can realize rapid centrifugation, can not influence developments, the static balancing of impeller, suitable large -traffic, high -power, prevent laying dust air flow transport.
Description
Technical field
This utility model relates to a kind of novel anti-laying dust draught fan impeller.
Background technology
Blower fan is by the power-equipment of gas conveying; have and be extremely widely applied; but the air-flow of most of use occasions all contains certain dust; during blower fan work; due to centrifugation when air-flow is by the draught fan impeller of high speed rotating, dust granule can depart from air-flow phase and deposit and be attached on draught fan impeller.
Owing to the rotating speed of draught fan impeller is general all higher, as long as air-flow there being trace dust exist, more dust all can be accumulated after working long hours, thus changing the balance that draught fan impeller rotates, if dust is not had self purification also without timely cleaning by draught fan impeller, will cumulative and progressively change static state and the dynamic equilibrium of draught fan impeller, thus producing vibration.Having the dust that hardens of part to be vibrated to come off, will balance away from the dynamic rotary of blower fan immediately, then produce judder once run into, this may cause serious personnel and equipment security incident.
Therefore, if a kind of draught fan impeller can be designed so that it is automatic cleaning can be carried out and just do not worry causing dust accumulate, for the reliable and stable work of maintenance blower fan with stop security incident all there is the meaning of particular importance.
Utility model content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, it is provided that a kind of simple and practical, can automatically clear up the novel anti-laying dust draught fan impeller of dust.
For overcoming the deficiencies in the prior art, this utility model takes techniques below scheme:
A kind of novel anti-laying dust draught fan impeller, including impeller backboard, impeller panel, primary blades and auxiliary blade, it is characterised in that: primary blades is flat panel contours and is arranged to impeller Axial and radial, centrosymmetric emitting shape；Primary blades connects impeller panel and is welded into impeller bodies with impeller backboard；Impeller panel is provided with air inlet, and impeller backboard connects into firm one by welding with blower fan axle bed with primary blades inner edge, and blower fan axle bed is connected by axis hole and fan shaft；Blower fan auxiliary blade and impeller panel, backboard, primary blades all constitute three-legged structure.
Compared with prior art, the beneficial effects of the utility model are in that:
The major-minor sharf radial center of blower fan is symmetrical, blade is when high speed rotating, blade surface has powerful eccentric surfaces self purification under powerful centrifugal action, dust cannot adhere to and can realize Quick spin separation, without influence on dynamic, the static equilibrium of impeller, it is suitable for big flow, laying dust air-flow high-power, anti-conveying.
The Axial and radial centrosymmetric structure that impeller panel, backboard, primary blades, auxiliary blade are all triangle, make its blower fan backboard connected and the anti-relative torsion of panel, extruding rigidity extremely strong, blower fan primary blades can be stopped completely and connect the fatigue fracture that backboard root causes because of carrying Moment, also higher intensity can be obtained by relatively thin board making, ensure to stablize, reliably use, the Impeller Design of this spline structure is particularly suitable for thin plate and makes, it is easy to save material, is conducive to light and handyization of equipment.
The draught fan impeller of such structural design by red dog minimum, even if having a small amount of dust attachment also due to centrifugal force shear action and cleared up at any time, it is ensured that the cleaning of impeller and dynamic and static balance.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
In figure, each label represents:
31, primary blades；32, auxiliary blade；33, impeller air inlet；34, blower fan axle bed；36, axis hole；37, impeller backboard；38, impeller panel.
Detailed description of the invention
In conjunction with accompanying drawing, this utility model is further elaborated with.
Novel anti-laying dust draught fan impeller as depicted in figs. 1 and 2, including impeller backboard 37, impeller panel 38, primary blades 31 and auxiliary blade 32, is arranged to impeller Axial and radial, centrosymmetric emitting shape by blower fan primary blades 31, blade be flat panel contours as shown in Figure 1.
Draught fan impeller connects impeller panel 38 by primary blades 31, and it is welded to form impeller bodies with impeller backboard 37, impeller panel 38 has air inlet 33, and backboard 37, primary blades 31 inner edge connect into firm one by welding with blower fan axle bed 34, and axle bed 34 is connected by axis hole 36 and fan shaft.
Blower fan auxiliary blade 32 such as Fig. 1 erection welding, three-legged structure is all constituted with impeller panel 38, backboard 37, primary blades 31, even if the light fan impeller making this spline structure with thin plate also has significantly high bearing capacity, it is suitable for big flow, laying dust air-flow high-power, anti-conveying.
When this draught fan impeller uses, owing to the major-minor sharf radial center of blower fan is symmetrical, blade is when high speed rotating, and blade surface has powerful eccentric surfaces self purification under powerful centrifugal action, dust cannot adhere to and can realize Quick spin separation, without influence on dynamic, the static equilibrium of impeller.
Above-mentioned simply preferred embodiment of the present utility model, not does any pro forma restriction to this utility model.Any those of ordinary skill in the art, when without departing from technical solutions of the utility model scope, all may utilize the technology contents of the disclosure above and technical solutions of the utility model are made many possible variations and modification, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content without departing from technical solutions of the utility model, according to this utility model technical spirit to any simple modification made for any of the above embodiments, equivalent variations and modification, all should drop in the scope of technical solutions of the utility model protection.
