Abstract
The utility model discloses a blade is wedge -form laying dust major axis fan wheel that prevents, including major axis and blade, the blade be rectangular shape, the blade profile be the impeller shaft radially, centrosymmetric cavity wedge, during the end plate was inserted at the blade both ends, the major axis passed through the spoke and connects and fix the end plate. The major axis middle part also is equipped with the end plate, and the end plate is passed by the blade, the reinforcing fastness. The utility model discloses design into the diameter of axle to the centrosymmetric structure with the blade, therefore the blade is high -speed when rotatory, the surface has powerful surperficial centrifugal self purification down in the effect of powerful centrifugal force, the rapid centrifugation of dust meeting, can't adhere to, can not influence developments, the static balancing of impeller, cavity wedge symmetrical structure makes the blade have very high anti -wind and bends bently and resist the crooked intensity of centrifugation, is favorable to lightly changing of save material and equipment, guarantees stably, reliably uses. The air -out of linear leaf fan wheel is even, wind -force mild and the wind pressure is less, and the occasion that is fit for needs air cycle such as air conditioner is used.
Description
Technical field
The utility model relates to a kind of draught fan impeller, specifically refers to that blade is the anti-laying dust long-shaft fan impeller of wedge shape.
Background technique
Blower fan is the power equipment carrying out gas conveying; have and apply extremely widely; but all contain certain dust in the air-flow of most of use occasion; during blower fan work; air-flow by during the draught fan impeller of High Rotation Speed due to centrifugation, dust granule can depart from air-flow phase and deposit and be attached on draught fan impeller.
Because the rotating speed of draught fan impeller is general all higher, as long as there is micro-dust to exist in air-flow, all more dust can be accumulated after working long hours, thus change the balance of draught fan impeller rotation, if draught fan impeller does not have self purification not clear up in time to dust yet, will cumulative and progressively change draught fan impeller Static and dynamic balance, thus produce vibration.Have the dust that part hardens to be come off by vibration once run into, will balance away from the dynamic rotary of blower fan immediately, then produce judder, this may cause serious personnel and device security accident.
Therefore, if can a kind of draught fan impeller be designed, Automatic clearance can be carried out and just do not worry causing dust accumulation, for keeping the reliable and stable work of blower fan and stopping the meaning that security incident all has particular importance.
Model utility content
The technical problems to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of simple and practical, and the blade of energy Automatic clearance dust is the anti-laying dust long-shaft fan impeller of wedge shape.
For overcoming the deficiencies in the prior art, the utility model takes following technological scheme:
Blade is an anti-laying dust long-shaft fan impeller for wedge shape, comprises major axis and blade, it is characterized in that: blade is long strip, and blade profile is that impeller shaft is radial, centrosymmetric hollow wedge; Blade two ends are inserted in end plate, and major axis is connected by spoke and fixes end plate.
Also be provided with end plate in the middle part of described major axis, end plate is passed by blade, strengthens soundness.
The cross section of long strip fan blade is arranged to impeller shaft radial direction, centrosymmetric hollow wedge, can be synthesized by single sheet metal flap, soldering group, make it have symmetrical profile, processing also more for convenience.
Major axis and fan shaft, after head and the tail end plate is connected major axis by spoke, linear leaf just forms impeller bodies through end plate.After major axis impeller integral-rotation, the spoke neutral on initial and end end plate is exactly intake grill, and linear leaf rotation is centrifugal by air, speed-raising is rear carries out wind-force output through blade.
The air-out of linear leaf draught fan impeller is even, and wind-force is mild and blast is less, is particularly suitable for the occasion use that air-conditioning etc. needs to carry out air circulation.
Compared with prior art, the beneficial effects of the utility model are also:
Because blade design becomes the centrosymmetric structure of Axial and radial, thus blade is when High Rotation Speed, surface has the centrifugal self purification in powerful surface under powerful centrifugal action, and dust can be separated, cannot adhere to by Quick spin, can not affect dynamic, the static equilibrium of impeller.
Blade design becomes hollow wedge symplex structure, make blade have very high Wind-Pressure Resistance bend and resist centrifugal bending intensity, also can obtain higher intensity with thinner board making draught fan impeller, be conducive to light and handyization of saving material and facility, ensure to stablize, reliably use; Compared with conventional tile blinds blower fan, there is the outstanding advantages that de-dirt self cleaning capacity is strong and intensity is high, adapt to special occasions requirements of one's work.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure schematic diagram of the present utility model.
Fig. 2 is close-up schematic view of the present utility model.
In figure, each label represents:
21, head end dish; 22, middle end plate; 23, tail end dish; 24, blade tip; 25, spoke; 26, linear leaf; 27, major axis.
Embodiment
Now by reference to the accompanying drawings, the utility model is illustrated further.
Blade is the anti-laying dust long-shaft fan impeller of wedge shape as depicted in figs. 1 and 2, and comprise major axis 27 and blade 26, blade is long strip, and blade profile is that impeller shaft is radial, centrosymmetric hollow wedge; Blade two ends are inserted in end plate 21,23, and major axis 27 is connected by spoke 25 and fixing end plate 21,23.
Also be provided with end plate 22 in the middle part of described major axis 27, end plate 22 is passed by blade 26, strengthens soundness.
The cross section of long strip fan blade is arranged to impeller shaft radial direction, centrosymmetric hollow wedge, can be synthesized by single sheet metal flap, soldering group, make it have symmetrical profile, processing also more for convenience.
Major axis 27 i.e. fan shaft, after head and the tail end plate 21,23 is connected major axis 27 by spoke, linear leaf 26 just forms impeller bodies through end plate 21,23.After major axis 27 impeller integral-rotation, spoke 25 neutral on initial and end end plate 21,23 is exactly intake grill, and linear leaf rotation is centrifugal by air, speed-raising is rear carries out wind-force output through blade 26.
Above-mentioned just preferred embodiment of the present utility model, not does any pro forma restriction to the utility model.Any those of ordinary skill in the art, when not departing from technical solutions of the utility model scope, the technology contents of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solutions of the utility model, or be revised as the Equivalent embodiments of equivalent variations.Therefore, every content not departing from technical solutions of the utility model, according to the 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.
