Abstract
The utility model relates to a multi-stage compound air filter belonging to the separation technology. The utility model aims at providing a multi-stage compound air filter of a coarse filter with good effect. The technical scheme has the following key points: the lower part of an air inlet cover is provided with a spiral flow channel; the outer edge of a bracket is connected with a lower end plate of a shell of a rotator component and an upper end of a shell of the coarse filter; the center of the bracket is provided with a hole with a cross rib plate, wherein the hole corresponds to a flow guiding pipe in the coarse filter below the hole; a shaft on the center of the rotator is rotatably supported in a bracket hole which is connected with the shell of the coarse filter in an opposite direction; outer ends of rotating plates which are uniformly distributed along the periphery are provided with scraping plates; arc-shaped dust-collecting plates are uniformly distributed between the scraping plates and the shell of the rotator component; a cavity with one wide end and one narrow end is formed between the arc-shaped dust-collecting plates and the shells of the rotator component; the bottom of the cavity is communicated with atmosphere; and a vertebral pipe at the lower end of the flow guiding pipe in the coarse filter is communicated with a fine filter. The multi-stage compound air filter is especially applicable to the air filtering of engineering trucks.
Description
Technical field:
The utility model relates to a kind of separator, particularly a kind of multipole composite air filtering device.
Background technology:
Engineering truck is because the airborne half dust content height of its operating environment, the air of cleaning offers diesel engine to existing air cleaner in order to obtain, before fine filter, increased one-level coarse filtration structure, but the filter effect of the coarse filtration structure of newly establishing is undesirable, causes fine filter short service life.
Summary of the invention;
The purpose of this utility model provides a kind of multistage composite air cleaner, the coarse filter good filtration effect of this filter.Technical solution of the present utility model is a kind of multistage composite air cleaner, comprise fine filter and coarse filter, it is characterized in that: the airscoop shroud bottom do not establish air admission hole the section in be provided with helical flow path, the shell upper end of rotating component is connected with the airscoop shroud lower end, the end plate of its lower end is connected with the shell of coarse filter, the outer rim of support is connected with coarse filtration shell upper end with the shell bottom plate of rotating component, the mozzle that this carriage center is provided with in the coarse filter of Kong Yuqi below of band crossed stiffened plate is relative, the supercentral axle of circulator rotational support with bracket holes that the coarse filter shell is connected in opposite directions in, the inner of the swivel plate that is uniformly distributed along the circumference is connected with circulator, the other end is provided with scraper plate, between the shell of scraper plate and rotating component, be evenly equipped with the arc collecting plate, form one the one narrow cavity of the wide other end of end between the shell of this arc collecting plate and rotating component, the bottom of this cavity communicates with atmosphere, and the Taper Pipe of the mozzle lower end in the coarse filter is communicated with fine filter.The utility model has the advantage of coarse filtration good filtration effect thereby filter long service life compared with the prior art.
Description of drawings:
Fig. 1 is the structural representation of the utility model multistage composite air cleaner, and Fig. 2 is the A-A cut-away view of Fig. 1
The specific embodiment:
In conjunction with above accompanying drawing the present invention is done detailed description, the helical flow path 4 that the coarse filtration of existing engineering truck multi-stage air cleaner is provided with by mozzle 3 and upper end thereof and the Taper Pipe 14 of mozzle lower end are formed, and airscoop shroud is arranged above mozzle.It is lower that but this one-level coarse filtration offers the air purity of smart filter, causes the life-span of smart filter to be reduced.In order to improve the filter effect of coarse filtration, in the cover body of airscoop shroud 11 not perforates of hypomere, be provided with helical flow path 10, be provided with rotating component below the airscoop shroud and between the coarse filtration, it comprises that the termination that is criss-cross swivel plate 6 swivel plates is provided with scraper plate 9, the inner of swivel plate is connected with circulator 12, axle rotational support on this circulator is in the hole of the support 5 that is connected with the coarse filtration shell, shell 7 upper ends of circulator are connected with the airscoop shroud lower end, its upper head plate is connected with support 5, between scraper plate 9 and shell 7, be uniformly distributed with 4 arc collecting plates 8 along the circumference, form the narrow cavity of the wide other end of an end between this collecting plate and the shell, going to the bottom of this cavity is communicated with atmosphere.
Work principle of filter of the present utility model is, air is after the air admission hole suction of airscoop shroud, in helical flow path the rotation make airborne dust be thrown to the outside enter in the shell of circulator, by scraper plate the base apertures of its cavity of blowing collecting plate from the chamber entered the atmosphere, air after the above-mentioned preliminary filtration enters mozzle, after being further rotated airborne dust, the helical flow path on mozzle top falls into the bottom along tube wall from the mozzle lower end and the looping pit between the Taper Pipe 14, enter Diesel Engine Exhaust Pipe through induction tunnel 2 and be discharged into atmosphere, and enter fine filter 1 through Taper Pipe 14 through the clean air behind the above-mentioned secondary filter, through entering diesel engine after the smart filter.The rotational power of the swivel plate on the circulator is, the direction of the air stream that air comes out from helical flow path with axially be an about angle of 30 °, this oblique air-flow makes the rotation of vertical swivel plate, drives scraper plate the dust on the bottom is scraped in the cavity between collecting plate and shell.
