Abstract
The invention discloses a filterable type centrifugal fan impeller. The filterable type centrifugal fan impeller is provided with a wheel shaft which is a cylindrical structure, wherein a shaft hole which is used for connecting a motor is formed in the center of the wheel shaft; a plurality of blades with equal included angles are uniformly arrayed at the periphery of the outer part of the wheel shaft; the blades are rectangular structures; hollow-out parts which are communicated with one another and are rectangular structures are arranged on front and rear surfaces of the blades; splicing holes which are rectangular structures are formed in the tops of the blades; the length of the splicing holes is greater than the height of the hollow-out parts; filter screens are spliced into the splicing holes; two side surfaces of each filter screen are positioned in the hollow-out parts on the blades; and the filter screens are fixed and limited by limiting covers which are arranged in the splicing holes in the tops of the blades. According to the filterable type centrifugal fan impeller, the filter screens are additionally arranged on the blades, and the blades continuously rotate to drive the filter screens to rotate, so that gas which flows through the blades of the impeller can be effectively filtered while air circulation is promoted, thereby guaranteeing cleanliness of gas, and generating positive effects on environment.
Description
technical field:
The present invention relates to air purification field, particularly relate 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 by this invention 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 present invention is achieved by 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.
