Description

Cyclone dust collectors

Technical field

The present invention relates to the deduster field.

Background technology

Usually, the principle that cyclone dust collectors utilize whirlwind is collected behind separating of garbage and the dust in the high velocity air, and with air row to the external world.

Fig. 1 is the longitudinal cross-section sketch of the cyclone dust collectors example of conventional art design, and Fig. 2 is the sectional view of the I-I part of Fig. 1.

As seen from the figure, cyclone dust collectors in the past comprise haply: conical cyclone fuselage 10; Suck the air intake duct 20 of air and various dirts; The dust arrester 40 of the blast pipe 30 of the air of discharge cyclone fuselage interior and dust that collection is separated from air and rubbish constitutes.

At this moment, air intake duct 20 is connected the upper end of cyclone fuselage 10 peripheries.

And blast pipe 30 is through to the upper end of cyclone fuselage 10 inside above cyclone fuselage 10, and is thus connected on fuselage.

And the other end of blast pipe 30 is connected on the suction generator 50 that transmits suction.

At this moment, suction generator 50 is to utilize motor 51 to rotate fan 52 and the parts of generation suction, omits detailed explanation here.

And the mudhole 11 that forms on dust arrester 40 and cyclone fuselage 10 bottom surfaces communicates.

As above the course of work of cyclone dust collectors in the past is as follows.

When suction generator 50 started, the extraneous air that contains dust and rubbish was sucked into the inside of cyclone fuselage 10.

At this moment, after the air intake duct 20 of the air that comprises dust and rubbish by cyclone fuselage 10 is sucked into inside from the tangential direction of cyclone fuselage 10, along the decline of circling round of the internal face of cyclone fuselage 10.

In this process, air and dirt are separated from each other thus owing to the center of circle power that weight differential is differed from one another.

That is, the big dirt of relative weight descends and is expelled in the dust arrester 40 by mudhole 11 along cyclone fuselage 10 internal faces under the effect of center of circle power, and the little air of relative weight is subjected to the suction of blast pipe 30 and is discharged to cyclone fuselage 10 outsides.

At this moment, the air that possesses weight is hardly run on cyclone fuselage 10 bottom surfaces and is formed ascending air along the central authorities of cyclone fuselage 10 under the effect of the suction of blast pipe 30, thereby is discharged to cyclone fuselage 10 outsides by blast pipe 30.

But, possessing in the cyclone dust collectors in the past of structure running as above, the cyclone path that flow into inner dust and rubbish is oversize, and dust and the overlong time that rubbish contacts with the cyclone internal face in the decline process of circling round can't reduce noise thus thus.

And inlet air flow path is long can only to increase pressure loss.

Moreover, various dirts also have remaining rotating force when entering the inside of dust arrester, can disperse thus to be collected in micronic dust in the dust arrester.

Thus, the micronic dust that disperses is discharged to cyclone fuselage outside along the ascending air that the bottom of cyclone fuselage forms by blast pipe, has not only reduced dust catching efficiency thus, and the micronic dust that disperses also can damage the suction generator.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 3 to Fig. 5 is the sketch of the cyclone dust collectors that design of the present invention.

That is, the cyclone dust collectors of the present invention's design comprise that cyclone fuselage 110, air intake duct 120, blast pipe 130, a plurality of mudhole and a plurality of dust arrester 140 constitute.

Cyclone fuselage 110 forms cylinder type on the whole.

And the effect of air intake duct 120 is that guiding enters cyclone fuselage 110 inside from extraneous inhaled air and various dirt, and its set-up mode is that a certain end that runs through cyclone fuselage 110 peripheral surface is connected on the fuselage.

At this moment, the part of air intake duct 120 is along the peripheral surface embowment of cyclone fuselage 110, and the connecting portion of intercommunication is in the tangential direction of cyclone fuselage 110.

Particularly, after air intake duct 120 bendings, the direction of the port of export that communicates with cyclone fuselage 110 inside is vertical mutually with the direction of the arrival end that sucks extraneous air.

And the effect of blast pipe 130 is to discharge the air that flow into the cyclone fuselage interior, and top (or following) that the one end runs through cyclone fuselage 110 is connected on the fuselage, and the other end is connected on the space that is provided with suction generators 150 such as fan electromotor.

Particularly, in an embodiment of the present invention, blast pipe 130 is connected with the top central part of cyclone fuselage 110.

And mudhole comprises the 1st mudhole 161 and the 2nd mudhole 162.

At this moment, the 1st mudhole 161 is arranged on the position of direction opposite face that air intake duct 120 on the cyclone fuselage 110 begins to suck air.

Specifically, the 1st mudhole 161 is arranged on the opposite of suction side of the suction outside air on air intake duct 120 peripheral surface.

That is, the 1st mudhole 161 being set is the inertia force gleanings dirt in advance that is subjected to when utilizing dirt to enter air intake duct 120.

And the 2nd mudhole 162 at intervals, is arranged on the cyclone path that flow into the dirt in the cyclone fuselage 110 in cyclone fuselage 110 peripheral surface and between the 1st mudhole 161.

Specifically, the 2nd mudhole 162 is arranged on the position, opposite of cyclone fuselage 110 and air intake duct 120 connecting portions.

That is, it is the low weight thing dirt of weight of not circling round in cyclone fuselage 110 inside from 161 discharges of the 1st mudhole in order to discharge that the 2nd mudhole 162 is set, and this short transverse along cyclone fuselage 110 forms long structure again.

And dust arrester 140 corresponding each mudholes 161,162 comprise that the 1st dust arrester 141 and the 2nd dust arrester 142 constitute the peripheral surface of surrounding cyclone fuselage 110 on the whole.

At this moment, the 1st dust arrester 141 communicates with the 1st mudhole 161, collects the dirt that the 1st mudhole 161 is discharged.

And the 2nd dust arrester 142 communicates with the 2nd mudhole 162, collects the dirt that the 2nd mudhole 162 is discharged.

A plurality of dust arresters 141 as above are set,, as consider shown in embodiments of the invention, to form the convenience made a cylindrical structure on the whole, and internal separation is become a plurality of spaces though 142 it doesn't matter.

At this moment, on the position that mudhole 161,162 is set of the inside of each dust arrester 141,142, be provided with the dividing plate 143 of separating each space.

The reason that as above makes dust arrester 140 corresponding each mudholes 161,162 form two control of dust spaces is to prevent that the dirt that enters in the dust arrester 140 from circling round, and prevents dispersing of dirt thus.

Particularly, among the present invention, the dual-side angular position of dust arrester 140 bends to arcuate structure in order to guide dirt to flow to the dividing plate in the dust arrester 140.

And the cyclone dust collectors of the present invention's design are provided with the inner space and are connected with the position that blast pipe 130 runs through in the inside of cyclone fuselage 110, and are provided with filter 160 formations of filtering material on peripheral surface.

The device upper end communicated with blast pipe 130 when at this moment, filter 160 formed cylinder type haply.

Particularly, the two ends of filter 160 be fixed on closely top in the cyclone fuselage 110 and below on, preventing comprising micronic dust in the air by blast pipe 130 outputs, thereby improve dust catching efficiency.

Constitute filter 160 filtering materials and can use various types of materials, therefore this is not limited.

Certainly, 160 couples of the present invention of filter are not set and can produce what influence yet.

Below, the course of action of the cyclone dust collectors of the present invention's design of as above constituting is carried out simple explanation.

After suction generator 150 started, the outside air that comprises dirt entered in the cyclone fuselage 110 by air intake duct 120.

At this moment, the air that comprises dirt was subjected to the effect of inertia force in air intake duct 120 before flowing into cyclone fuselage 110 inside.

Thus, the dirt that is subjected to inertia force has little time to enter in the cyclone fuselage 110 and is discharged in the 1st dust arrester 141 by the 1st mudhole 161 that forms on the air intake duct 120 and the port of export that cyclone fuselage 110 communicates.

At this moment, the dirt collected of the 1st dust arrester 141 generally is the heavier dirt of weight.

Then, the suffered less dirt of inertia force in above-mentioned process promptly under the effect of the suction of the dirt that weight is lighter in cyclone fuselage 110, behind the 1st mudhole 161, enters cyclone fuselage 110 inside by the port of export of air intake duct 120.

At this moment, because of the port of export of air intake duct 120 is arranged on the tangent line of cyclone fuselage 110, dirt circles round along the internal face of cyclone fuselage 110 thus.

Therefore and air separation in this process,,, thereby have only air, and discharge by blast pipe 130 through filter 160 because of dirt is subjected to the effect of center of circle power.

And the 2nd mudhole 162 that forms on by internal face in the process that the various dirts that circle round in cyclone fuselage 110 inside are circling round enters the inside of the 2nd dust arrester 142.

Simultaneously, in the middle of the carrying out of above-mentioned a series of processes, the dirt that enters into the 1st dust arrester 141 inside by the 1st mudhole 161 is position, the corner output of the 1st dust arrester 141 by its inflow direction opposite directly.

But because of above-mentioned position, corner bends to arcuate structure towards dividing plate, so dirt can be mobile along cambered surface, and bump against the flowing velocity of slowing down on the dividing plate 143 of dividing each control of dust space in process of flowing, finally stays on the bottom surface of the 1st dust arrester 141.

Moreover, enter of the corner position output of the dirt of the 2nd dust arrester 142 inside by the 2nd mudhole 162, and in output procedure, flow to dividing plate 143 along curved wall by the 2nd dust arrester 142 on its inflow direction opposite.

Thus, the rotating force that enters the dirt in the 2nd dust arrester 142 reduces, and dirt all focuses on the bottom of the 2nd dust arrester 142 thus
