Description
Technical field:
The present invention relates to a kind of dust-separating appliance.
Background technology:
The centrifugal separating device of separating particles is known by people from streaming flow, on the principle according to such one simple true: in closed container, form spiral air flow, utilize dust density greater than air, be subjected to the characteristic of big centrifugal force, make dust be close to wall, by certain specific structure these dusts are collected and disposed then.Known existing centrifugation dust catcher generally adopts the separate mode of double-filtration, and the first order adopts the centrifugation mode, and centrifugation mode or traditional forced filtration are adopted in the second level.General two-stage isolating construction often all is sealed in the same cylinder base, and during use, air is introduced into first order poor efficiency whizzer, and then by an air duct, enters inner second level high performance centrifugal separator or dust screen pack again.Like this, because all first order isolating construction and second level isolating construction being arranged in the same cylinder base of sealing longitudinally all then can make cylinder base inside have complex structure, the disadvantage that sealing part is too much.Simultaneously, this sealing part is too much, usually can make the dirt tube form some laying dust dead angles, thereby, in the process that the user uses, tend to the phenomenon that the difficulty of falling dirt occurs and be difficult to clean up.
Summary of the invention:
In order to improve above-mentioned various shortcomings,, create a kind of dust-separating appliance of the present invention finally through the continuous effort of creator.
Below in conjunction with the drawings and specific embodiments mode to further detailed explanation of the present invention.
Fig. 1 is an assembling exploded perspective view of the present invention;
Fig. 2 is a side sectional view of the present invention;
Fig. 3 is the perspective view that the present invention forms the cover of Fig. 1 institute view apparatus part.
The specific embodiment:
As Fig. 1, shown in Figure 3, comprise a cover 1 on the structure of the present invention, in present embodiment, this cover 1 is provided with the type semienclosed big or small bitubular 11,12, connect with each other at its semi-enclosed aperture position place between this size tube 11,12, this cover 1 is provided with and is respectively equipped with inlet 111, outlet 112, in present embodiment, this inlet 111 is positioned at the side of its big tube 11, when its structure is to pass air into, air-flow enters with the approximate inner surface 113 that is tangential on cover 1, in addition, is provided with a spiral interception mouth 114 along little 12 axis.Axis along above-mentioned big tube 11 has been provided with a column structure 115, it is characterized in that its middle and upper part is cylindrical-shaped structure, and it is hemispherical that the bottom is, ellipticity or coniform, and its arbitrary section perpendicular to the axis is circular.
What be sealed and matched with cover 1 is a cylinder base 2, and in present embodiment, its outward appearance also is big or small double-barrel structure, and this size bitubular interconnects and be separate.The tube of its big volume constitutes bulky grain dust collecting region 21, and its inner surface also is used as the face that circles round 211 of air stream.The less tube of volume has then constituted fine dust collecting region 22.
As Fig. 1, shown in Figure 2, between cover 1 and cylinder base 2, be provided with a sedimentator 3.This sedimentator 3 is provided with first order isolating construction 31 and second level isolating construction 32, and this first isolating construction 31 and second isolating construction 32 are laterally to link together mutually by an air accelerated passage 33.
In present embodiment, described first isolating construction 31 is to be cylindric, is provided with guide vane 311 along cylinder ring shape direction on this first isolating construction 31, when its architectural feature is that air is flowed through, can obtain a downward velocity component.Its underpart barrel is made up of filter screen structure 312, and the bottom is provided with a parallel base plate 313.This filter screen structure 312 extends downwards, forms a flange portion 314.In addition, the column structure 115 of described cover 1, its length can be deep in the filter screen structure 313 in this sedimentator 3, its role is to steady air flow, reduces noise.Second isolating construction 32 of this sedimentator 3 is a cone-shaped structure in present embodiment, and its radius dwindles from top to bottom gradually, and these second isolating construction, 32 bottoms also are provided with dust mouth 321.
Above-mentioned air accelerated passage 33, its architectural feature are that air passes through its air accelerated passage 33 backs and obtains to quicken, and enter in second isolating construction 32 with tangential way and to go.Its air accelerated passage 33 can be designed to a kind of like this structure: this section is parallel construction by cover 1 and sedimentator 3 respectively up and down, and air is entered in second isolating construction 32 with the parallel mode tangent line.
Dust-separating appliance of the present invention divides by functional area, is divided into the double-filtration Disengagement zone.Wherein the first order isolating construction 31 of the bulky grain dust collecting region 21 of cover 1, cylinder base 2 and sedimentator 2 constitutes first order Disengagement zone, and second isolating construction 32 of the granule dust collecting region 22 of cover 1, cylinder base 2 and sedimentator 3 constitutes Disengagement zone, the second level.Wherein Disengagement zone, the second level can be more than one, but two or more, corresponding therewith, and second isolating construction 32 of sedimentator 3 also can have a plurality of cone-shaped structures.
Apparatus of the present invention are generally used in the following manner.The air that carries dust enters by 111 tangent lines that enter the mouth, and under the effect of guide vane 311, obtains a downward velocity component, air is finally spinned along the inner surface of bulky grain dust collecting region 21 move downward.When moving to the bottom of bulky grain dust collecting region 21, again oppositely on, form the interior eddy flow on the screw, oarse-grained dust then can be collected bulky grain dust collecting region 21.Inward turning flows to when going up motion; finally be subjected to stopping of parallel base plate 313 and flange portion 314; the part dust bulky grain dust collecting region 21 that falls back that rebounds again, a part of then rebound to the screw downstream at the inner surface place of dirt tube, bulky grain dust collecting region 21 again falls back.Substantially dried quiet air then enters in the second level isolating construction 32 of sedimentator 3 by filter screen structure 312.It more than is first order filter process.
, obtain to quicken at air accelerated passage 33 by behind the filter screen structure 312 of sedimentator 3 through first order filtered air, in a parallel manner, tangent line enters second level isolating construction 32, and for the helical movement.Because second level isolating construction 32 is cone-shaped structure, diminishes gradually along its axial direction radius, according to centrifugal force formula: F=MV
2/ R as can be known, radius and centrifugal force are inversely proportional to, radius constantly reduces, centrifugal force constantly increases, dust in air is under powerful action of centrifugal force, be thrown toward the inner surface of second level separate structure 32, and move downward, fall into fine dust collecting region 22 in the dust mouth 321 of second level separate structure 32 bottoms at last along this surface.Only then discharge dust collect plant along the spiral interception mouth on the cover 1 114 with the air of the fine dust of minute quantity.It more than is second level filter process.
The above only for most preferred embodiment of the present invention, is allly done impartial conversion according to present embodiment and all drops within protection scope of the present invention.
