Description

The cyclone separator of dust catcher

Technical field

The utility model relates to the device of separating particles in a kind of fluid air flow, particularly the cyclone separator of particle such as a kind of dust-separating and use the dust catcher of this device.

Background technology

Cyclone separator is a kind of centrifugal force divided gas flow that produces through the air-flow of whirlwind tube high speed rotation and the device of dust dirt.Usually adopt in the prior art two stage cyclone separator is connected.Make the air that contains dust through the oarse-grained dust of the preliminary elimination of upper reaches cyclone separator,, thereby reach the effect that purifies air again through the further elimination dust granule of downstream cyclone separator.

But, the structure of two stage cyclone separator series connection when having improved cleaning efficiency, the also volume of inevitable aggrandizement apparatus, particularly vertical volume has brought inconvenience to user's operation; Very long gas connecting path between the two stage cyclone separator also makes manufacture process seem very complicated in addition, and part count and manufacturing cost are increased.

The utility model content

The utility model is in order to overcome defective in the above-mentioned prior art, through the bispin wind system of mutual sheathing, has guaranteed that effectively the volume, structure of bispin wind system is compact more, and centrifugal dust-removing efficient is higher.

The vacuum cleaner cyclone separator of the utility model comprises the whirlwind staving, in the whirlwind staving, establishes coaxial outer mesh filter and interior mesh filter, and interior mesh filter is sleeved on outer mesh filter interior; Outer mesh filter side is established air inlet, and interior mesh filter top sets out the air port; Outward, interior mesh filter establishes the tangential gas flow passage at the top, outer, the interior mesh filter through mutual sheathing forms two stage cyclone and separates.

Preferably, secondary whirlwind tangential gas flow passage is located between said outer, the interior mesh filter top, evenly is provided with at interval in a circumferential direction.

Wherein, in the whirlwind staving, the bulky grain dust storage chamber is established in outer mesh filter below; In the whirlwind staving, thin grey dust storage chamber is established in interior mesh filter below; Inside and outside mesh filter bottom is set up the shirt rim that is used to collect hair, hair thing separately.

Wherein, dust catcher also comprises loam cake and the bottom that lays respectively at said whirlwind staving upper and lower sides, is used for the sealing of whirlwind staving; For the ease of Fixed-Filter, in loam cake, the filtration rack that is used for supporting filter is established in the corresponding position of inside and outside mesh filter; The bottom button that is used to dismantle bottom is established in the junction of whirlwind staving and bottom.

Compared with prior art; The cyclone separator of the utility model dust catcher through mutual sheathing inside and outside mesh filter and between the tangential gas flow inlet; Make this apparatus structure compact, centrifugal dust-removing efficient is high, has effectively avoided the secondary pollution in the dust catcher use.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail, but the protection domain that is to be understood that the utility model does not receive the restriction of the specific embodiment.

As shown in Figure 1, the cyclone separator of the dust catcher of the utility model comprises the loam cake 1, filtration rack 2, Internal handle 3, interior mesh filter 4, outer mesh filter 5, whirlwind staving 6 and the bottom 7 that connect successively; On cover and establish handle 1a; The bottom button is established in the junction of bottom and whirlwind staving 6, is convenient to the dismounting of bottom.

To shown in Figure 5, outer mesh filter 5 all is located in the whirlwind staving 6 with interior mesh filter 4 like Fig. 2, and interior mesh filter is sleeved on outer mesh filter interior, and coaxial setting.Outer mesh filter side is established air inlet 8, communicates with the air inlet in the whirlwind staving outside, and interior mesh filter 4 tops set out the air port; Tangential gas flow passage (the be tangential inlet 12) connection of interior mesh filter through being located at the top, air inlet 8, outer mesh filter 5, tangential inlet 12, interior mesh filter 4 and the complete turnover wind passage of air outlet 9 formation so outward.Outer, interior mesh filter through mutual sheathing forms the two stage cyclone separation.

In the whirlwind staving 6, bulky grain dust storage chamber 10 is established in outer mesh filter 5 belows; In the whirlwind staving 6, thin grey dust storage chamber 11 is established in interior mesh filter 4 belows.Inside and outside mesh filter bottom is set up the shirt rim 13 that is used to collect hair, hair thing separately, and shirt rim and filter are structure as a whole.For the ease of fixing inside and outside mesh filter, inner at loam cake, the filtration rack 2 that is used for supporting filter is established in the corresponding position of inside and outside mesh filter.

Brief description dust suction process once: at first; Pass through swabbing action; The air-flow of air entrained dirt is mesh filter 5 outside air inlet 8 gets into, and (being the outboard chambers of whirlwind staving 6 inside and outside mesh filter 5) air-flow is done the centrifugal cyclone motion in poor efficiency whirlwind bucket, and the bulky grain dust is collected in the bulky grain dust storage chamber 10 of poor efficiency whirlwind bucket bottom; Mesh filter 4 in the air-flow of carrying thin ash secretly moves upward and gets into, this moment, first order cyclonic separation finished; Then, carry the air communication of thin ash secretly and cross mesh filter 4 in the entering of tangential gas flow passage, this tangential gas flow passage, outside being located at, between the interior mesh filter top, and evenly setting at interval in a circumferential direction, as shown in Figure 4.The air communication of carrying thin ash secretly cross this plurality of channels get in mesh filter 4 carry out second level cyclonic separation; Promptly thin ash is collected under action of centrifugal force in the thin grey dust storage chamber 11 of efficient cyclone tube bottom; Clean simultaneously air is upwards discharged through air outlet 9; Get into motor again through filtering, this moment, second level cyclonic separation finished.So far, the rotation of the inside and outside mesh filter through suit can realize that two stage cyclone separates and sedimentation and filtration.

The cyclone separator compact conformation of the dust catcher of the utility model; Centrifugal dust-removing efficient is high, realizes effectively that in the confined space two stage cyclone filters, and has reduced the pressure loss of whole dust catcher; Improve its sustainable ability of inhaling ash, avoided the secondary pollution in the dust catcher use.

More than a disclosed specific embodiment that is merely the utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into the protection domain of the utility model.
