The specific embodiment
Below in conjunction with the drawings and specific embodiments cyclone dust collectors of the present invention are described in further detail:
Shown in Fig. 3,4,5, the cyclone dust collectors of the present invention design comprise cyclone fuselage 110, dirt separation 130, dust arrester 140 and directly are connected cyclone fuselage 110 and the suction generator 150 that directly is connected on the dirt separation 130 constitutes.
The cyclone fuselage 110 that constitutes cyclone dust collectors adopts width (diameter) to be equal to or greater than the cylinder type of height, and has connected the air intake duct 120 that sucks outside air, also is provided with the mudhole 111 of discharging dirt.
The dust arrester 140 of above-mentioned cyclone dust collectors can adopt cylinder type, but also can adopt the structure of tetragonal body or polyhedron etc., and on certain one side therein combined hole 142 is set.
Can insert the mudhole 111 that is arranged on the cyclone fuselage 110 in the combined hole 142 of dust arrester 140, the two combines.
The eddy current that flows that has also possessed the interference dirt in the inside of dust arrester 140 prevents guide plate 141, and eddy current prevents that guide plate 141 is arranged on the bottom surface of dust arrester 140, has certain height, is back to the upright tabular next door of the flow direction of dirt.
Eddy current prevents that the height of plate 141 is lower than the whole height of dust arrester 140, and concrete employing can prevent to form at the dirt of dust arrester 140 internal flows the height of eddy current effectively.This there is not concrete limit value.
Eddy current prevents that the main effect of guide plate 141 from being to prevent that the micronic dust that enters in the dust arrester 140 from rotating in dust arrester 140.So the micronic dust that having prevented disperses causes enters the phenomenon of cyclone fuselage 110 inside once more.
And, after dust arrester 140 and 110 combinations of cyclone fuselage, can optionally split each other.
The dirt separation 130 of cyclone dust collectors adopts the cylinder type filtering bodies of the hollow state of the internal diameter with a certain size, and its direction is identical with the direction of 110 on cyclone fuselage, and simultaneously, the inside of hollow state links to each other with suction generator 150.It is the effect that the inner space of dirt separation 130 plays blast pipe.Particularly the height of dirt separation 130 is identical with the height of cyclone fuselage 110.
The suction generator 150 of cyclone dust collectors comprises the frame 151 that directly is connected on the dirt separation 130 and is arranged on the interior blowing fan 152 of frame and the drive motors 153 of driving blowing fan.Except the position that is communicated with each other, other parts have all been carried out encapsulation process between frame 151 and the dirt separation 130.
Below, describe by the order of action working method the cyclone dust collectors of the present invention's design of as above constituting:
After suction generator 150 started, the extraneous air that comprises dirt was sucked in the cyclone fuselage 110 by air intake duct 120.In this process, the air intake duct 120 of the air that comprises dirt by cyclone fuselage 110 enters fuselage interior from the tangential direction of cyclone fuselage 110.Then, the effect of the center of circle power that air and dirt are varied in size by weight differential is separated from each other.Be that the big dirt of weight is under the effect in the center of circle, in the way that the internal face of cyclone fuselage 110 circles round, be discharged in the dust arrester 140 by the mudhole 111 that is arranged on cyclone fuselage 110 inside, and the little air of relative weight is expelled in the space that suction generator 150 is set by behind the dirt separation 130.
At this moment, because of not having flow path on the connection position between mudhole 111 and the dust arrester 140, can farthest prevent the pressure loss and noise.And in above-mentioned a series of process, the dirt that is entered dust arrester 140 inside by mudhole 111 also has the rotating force that is subjected to when beginning to flow into, and therefore circles round in dust arrester 140.Because dust arrester 140 inside of the present invention's design are provided with eddy current and prevent guide plate 141, prevent to lose rotating force on the guide plate 141 so the dirt that circles round in dust arrester 140 all can bump against eddy current.Dirt disperses never again, and carries out the movement of falling object by self gravity, focuses on the bottom of dust arrester 140.
In the process of trapped dirt, because of dirt separation 130 adopts the filtering bodies of the cylinder type of hollows, so dirt can't be stayed cyclone fuselage 110 inside by dirt separation 130 with after the air separation.Have only clean air to be expelled in the suction generator 150, prevented the damage of the suction generator 150 that dirt causes.Particularly,, therefore there is not flow path each other, farthest prevented the pressure loss and the noise that cause by flow path because of suction generator 150 directly links to each other with dirt separation 130.
In above-mentioned process, the dirt that not being able to do in time in the dirt that circles round along cyclone fuselage 110 discharged from mudhole 111 and circling round along the inwall of cyclone fuselage 110 once more from the dirt that air separation goes out forcibly by dirt separation 130, and be expelled to the inside of dust arrester 140 by mudhole 111.
By carrying out said process repeatedly, after dirt collection totally, begin to discharge the dirts of collecting in the dust arrester 140.Because dust arrester 140 in the cyclone fuselage, be arranged to can dismounting structure, can pour out dirt easily.Particularly, in above-mentioned process, be not able to do in time to be discharged to dust arrester 140 and the various dirts that residue in the cyclone fuselage 110 must be cleaned out from mudhole 111.
In the present invention, make dirt separation 130 and suction generator 150 be arranged to mutually can dismounting structure, can remove the dirt of cyclone fuselage 110 inside easily.Certainly, also can be arranged to above the cyclone fuselage 110 can switch structure, discharge dirt and cleaning dirt separation 130 easily.
The eddy current of the present invention's design prevents that guide plate from not being that a part of structure that only is applicable to the cyclone fuselage is inserted the interior situation of dust arrester.As shown in Figure 6, also can be used on the dust arrester 140 of the direct-connected cyclone dust collectors that have been equipped with independent blow-off pipe 160, omit its explanation here.
