Description

A kind of cyclone separator

Technical field

The utility model relates to the dust catcher field, the cyclone separator that being used for of being specifically related to use in dust catcher filters air dust.

Background technology

Accompanying drawing 1 is depicted as the tomograph of the one-level cyclone separator of prior art, it comprises dirt gas inlet 11`, whirlwind tube 1 ', be positioned at the inner 2` of cyclone separating chamber of described whirlwind tube 1 ', be positioned at the filter 3 ' of the described 2` of cyclone separating chamber, cyclone separating chamber 2 ' enters the mouth with dirt gas and is connected by dirt gas passage 13 between the 11`, and filter 3 ' communicates with the air outlet 31 ' of cyclone separator.

After impure dirt gas is inhaled into the 2` of cyclone separating chamber by dirt gas inlet 11 ', dirt gas enters in the 2` of cyclone separating chamber along tangent line, wherein the grit that density is bigger is thrown toward under centrifugal action on the 2` of the cyclone separating chamber inwall, and enter in the dust storage chamber 12` by dust-exhausting port 25 and to collect, gather and in cylindrical shell, shrink to the center through the air-flow of the rotation after the centrifugal filtration, upwards form the secondary eddy current and from filter 3 ', extract out and be brought into dust catcher top and filter once more, after the venthole of dust catcher discharge.

When using dust catcher cleaning floor; Shi Changhui cleans out a large amount of hairs that human body drops; in the family that some keep a pet; also can clean out a large amount of pet hairs; " dust " of these pet hairs and hair and similar filiform will be wrapped on the filter 3 ' after entering the 2` of cyclone separating chamber by dirt gas inlet 11`; and the obstruction of the filtering holes on the filter 3 ', thereby reduced dust catcher suction, and make the cleaning efficiency of dust catcher descend.

In order to overcome above-mentioned shortcoming, the utility model patent of Chinese patent CN 202277305 U: dust cup of dust collector with spiral dirt bowl cover, it is provided with the spirally-guided device that the dust that prevents in the dust storage chamber 12` raises up in dust storage chamber 12` inside, to be used for stoping the dust in the dust storage chamber to be back in the cyclone chamber, avoid similar filiform such as hair, long fibre to be wrapped on the filter 3 ' simultaneously in dust storage chamber 12` inside; Chinese patent CN202184687U also discloses a kind of cyclone separator, it has secondary cyclonic separation function, for avoiding hair or long fibre to influence dust collection efficiency, it adopts the mode in the sheathed mesh filter in the secondary whirlwind tube outside, the same with other most cyclone separators, the screen pack of above-mentioned two kinds of cyclone separators is the plane, the mesh area is limited on the one hand, dust collection efficiency is not high, on the other hand, when dust-contained airflow from filter surfaces through out-of-date, the screen pack on plane is very little to the disturbance that air-flow produces, hair and long fibre be along with the rotational flow of air-flow is easy to hang on the filtering holes, thereby cause filtering holes to be stopped up.

The utility model content

The utility model has overcome that hair and long fibre twine filter, stop up the problem of filtering holes in the dust catcher of prior art, and provides a kind of simple in structure, low processing cost and a kind of cyclone separator of being convenient to clean.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of cyclone separator, core tube and the conical filter that is positioned at described core tube inside that described cyclone separator comprises the whirlwind tube with dirt gas inlet and is positioned at described whirlwind tube inside, surround the single stage of dust collection chamber between the outside wall surface of the internal face of described whirlwind tube and described core tube, the inner chamber of described core tube forms the secondary dust storage chamber, offer the secondary air intake vent that is connected with described single stage of dust collection chamber on the described core tube, offer a plurality of secondary air outlets on the described conical filter, the indoor dividing plate that is used to filter elementary big ash and hair that also is provided with of described single stage of dust collection, and there is part surface to arch upward and form filter house on the described dividing plate, offers a plurality of filtering holes on the described filter house towards direction away from described secondary air intake vent.

In the preferred version, offer a plurality of described filter houses on the described dividing plate, a plurality of described filter houses along the circumferential direction are distributed on the described dividing plate.

In the preferred version, described filter house is tapered, and the outer surface of described filter house is the conical surface.

In the preferred version, the filtering holes on the described filter house is the slotted hole along the bus extension of taper.

In the preferred version, the outer surface of described filter house is a sphere.

In the preferred version, offer a described filter house on the described dividing plate, and described filter house is along the circumferential extension of described cyclone separator.

In the preferred version, also be provided with the cyclonic separation awl in the described core tube, described conical filter is positioned at described cyclonic separation awl, and the bottom of described cyclonic separation awl has the ash hole that communicates with described secondary dust storage chamber.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

The baffle surface of cyclone separator is uneven, and lobed filter house, these filter houses can increase the gross area of filter mesh, improve dust collection efficiency, and rough surface can also cause small sinuous flow near dividing plate, make near the motion of the gas of dividing plate have disturbance, and then make hair or long fibre person be not easy to stop up filtering holes.
