This kind of can strain formula centrifugal fan impeller sets up the filter screen on the blade, through the continuous rotation drive filter screen rotation of blade, the gas to the impeller blade that flows through when promoting the circulation of air can filter effectively to guarantee gaseous cleanliness factor, produce positive effect to the environment.
Description
technical field:
The utility model relates to air purification field, particularly relates to one and can filter formula centrifugal blower fan blade wheel.
background technique:
Its working principle of centrifugal fan be air-flow by fan shaft to entering blade space, then at the driving further aspect of impeller with vane rotary, under the effect of inertia, improve energy on the other hand, leave impeller along radial direction, the centrifugal force by generation does work.
Centrifugal fan is the conventional supplement production equipment of the more enterprise of dust production; be mainly used in ventilating with dust removal apparatus; as in stone material cutting and polishing operation, cyclone dust collector and sack cleaner etc. all need to utilize centrifugal fan to carry out dust removal process to production site; guarantee that production environment is clean, the protection producer is physically and mentally healthy.
In order to ensure gas flow, impeller is the vitals in centrifugal blower.Existing impeller is all single lamellar body, and its function plays the effect driving airflow, but how much gas being through impeller has certain pollution, enters indoor or outdoors and all can pollute air.
summary of the invention:
Technical problem to be solved in the utility model is, provides a kind of filtered formula centrifugal blower fan blade wheel that can filter the gas flowing through impeller.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: one can filter formula centrifugal blower fan blade wheel, there is the wheel shaft of cylindrical structure, the center of described wheel shaft is provided with the axis hole for connecting motor, outside surrounding uniform array has the blade that some angles are equal, the rectangular structure of described blade, its front-back is provided with the hollow out of mutually through and rectangular structure, top is provided with the spliced eye of rectangular structure, the degree of depth of described spliced eye is longer than the height of hollow out, filter screen is plugged with in described spliced eye, the bi-side of described filter screen are positioned at the hollow out on blade, and this filter screen is fixed spacing by the spacing cover plate be arranged on vane tip spliced eye.
As preferably, the bottom of described spacing cover plate is provided with two symmetrical elastic limit potential heads, and described blade is provided with two positioning holes mutually corresponding with described elastic limit potential head position, in described positioning hole penetrating blade inside and outside spliced eye.
As preferably, bottom described spacing cover plate, two symmetrical elastic limit potential heads have two groups.
As preferably, the bottom surface of described spacing cover plate is provided with spongy layer.
As preferably, the surperficial undulate of described filter screen.
Compared with prior art, usefulness of the present utility model is: this formula centrifugal blower fan blade wheel of filtering sets up filter screen on blade, rotated by the continuous rotating band electric filter of blade, can effectively filter the gas flowing through impeller blade while promotion air circulation, thus ensure the cleanliness of gas, good effect is produced to environment.
