Abstract

A vortex type dust cup of a dust collector with the function of thrice separating includes a crust body, an air inlet that is arranged at the crust body and is tangent with the crust body and a separator, which is arranged inside the crust body. Certain fall height is arranged between the level position of the top of the air inlet of the separator and the central position of the dust cup air inlet. The separator is provided with two pieces of an internal pipe and an external pipe, which are coaxially installed. The bottoms of the internal pipe and the external pipe are in close connection. The height of the internal pipe is lower than the height of the external pipe. The air inlet of the separator is an annular body and is formed by the screw-thread-shaped rotary arrangement of screw panels, and the bottom of the separator is fixed at a separating cover. The middle of the internal pipe above a central hole of the separator is connected with a central pipe, which is coaxial with the internal pipe. The central pipe is put through the separating cover and extends downwards to form an extending pipe, which is provided with a small top and a big bottom. A short pipe is arranged inside the lower part of the extending pipe and links the extending pipe, the short pipe and the bottom of the crust body as a dust cup air outlet, which is provided with a trumpet-shaped convex edge. The extending pipe under the separator is provided with a three-vane rotating plate inside. The separation effect towards the air with dust can be further strengthened by thrice separating through the dust cup internal cavity.

Technical field

The present invention relates to a kind of dust catcher manufacturing technology field, especially refer to the separator of centrifugal aspirator air and dust.

Background technology

The application number that I have applied for is " 200510049880.2 ", " dust cup of dust collector of twice separation of integral type ", though the effect than prior art separation of air and dust improves a lot, but still have a small amount of thin dirt without separating along with air stream is adsorbed on the filter of dust catcher, after repeatedly using, still build up more dust on the filter, the circulation of having blocked air in the course of time, it is necessary producing a better separator of separating effect on the original basis for this reason.

Summary of the invention

The technical problem to be solved in the present invention is that its separating effect of dust cup of dust collector with twice separation function is desirable not enough, also has a small amount of unsegregated thin dust along with air stream is adsorbed on the filter.

The technical scheme that the present invention solves its technical problem is: increase the first separation function again in having the dust cup of dust collector of twice separation function, make it become a dust cup of dust collector with tri-separation function.It comprises housing, be opened in the air outlet on the housing, the air inlet and the separator be located at housing in tangent with the housing perisporium, described separator is provided with air inlet, the centre bit of the horizontal level at separator air inlet top and dirt cup air inlet is equipped with certain drop height, and the air inlet below of separator is provided with cage, and described separator is provided with two coaxial mounted inner and outer pipes, the inner and outer pipes bottom lock connects, and the height of interior pipe is lower than the outer tube height; The separator air inlet communicates by interior Guan Yuchen cup air outlet; Described separator air inlet is body in the form of a ring, rotates uniform arrangement by screw thread rotation arrangement or a plurality of flight by the multiple thread shape by a flight and forms; Described dirt cup air outlet is opened in the bottom of housing; The separator top links to each other with the sealing connecting portion of inner and outer pipes, and separator links to each other with housing in the bayonet socket mode by outer tube.Separator air inlet bottom is fixed on the described cage of band centre bore.Connect a central tube coaxial with interior pipe in the cage centre bore top in the middle of the pipe, be provided with the extension that is in same axis with central tube below the cage, this extension is that top is little, the bottom is big.Establish a short tube in the extension lower end, and make extension, short tube and housing bottom be connected to form the described air outlet of flared fingers, central tube communicates with the housing bottom air outlet by extension and short tube.Constitute the dust cup of dust collector of three separation like this.Through first separation, isolate most dusts.Gap in the air of slightly a small amount of thin dirt is entered by separator ring-type air inlet between pipe and the central tube.Owing to be subjected to the guide effect of flight, make the air that enters slightly a small amount of thin dirt in the gap produce swirling eddy equally.Radius of turn increases suddenly when upper end pipe in this part air rises to, and blast reduces, and centrifugal force will mix to separate to get rid of to outer tube wall and along the wall rotation in airborne a small amount of thin dirt and fall.And the air after separating enters extension downwards through central tube.

Further, one or three leaf revolving fragments are set in above the extension expansion section, through after the secondary separation because the effect of three leaf revolving fragments of extension, air after the separation continues rotation downwards, as the also slightly a small amount of thin dirt of this part air, then, this part air increases suddenly when dropping to bottom upper end of short tube rear screw radius, blast reduces, centrifugal force will mix once more in the thin dirt of airborne minute quantity and separate, get rid of to bottom extension expansion section inwall and along the wall rotation and fall, can further increase separating effect.

The specific embodiment

Fig. 1 is extremely shown in Figure 3 to be the embodiment of product of the present invention.As shown in the figure, this dirt cup comprises dirt cup housing 13, is located at the tangent with it dirt cup air inlet 1 of dirt cup housing 13 perisporiums and places the interior separator of dirt cup, described separator is provided with air inlet 6, the centre bit of the horizontal level at separator air inlet top and dirt cup air inlet is equipped with certain drop height, the below of separator air inlet 6 is provided with cage 7, and the air inlet 6 of separator communicates with dirt cup air inlet 1.Described separator air inlet top is connected with two coaxial interior pipes 8 and outer tube 9, and interior pipe 8 outer walls are connected with the bottom lock of outer tube 9 inwalls, and wherein interior pipe 8 communicates with being arranged at dirt cup bottom air outlet 3, and interior pipe 8 is shorter than outer tube 9.Separator is connected with dirt cup top in the bayonet socket mode by outer tube 9.Described separator air inlet 6 is arranged by the screw-like rotation by a flight 12 or a plurality of flight rotates uniform rearranging by the multiple thread shape.The top of separator air inlet 6 links to each other with inner and outer pipes 8,9 bottom lock connecting portions, its bottom is fixed on the described cage 7 of band centre bore, connect a central tube 4 coaxial in the cage centre bore top in the middle of the pipe with interior pipe 8, the cage below is provided with the extension 14 that is in same axis with central tube, this extension 14 is that top is little, the bottom is big, establish a short tube 11 in the extension lower end, and making extension, short tube and housing bottom be connected to form the air outlet 3 of flared fingers 17, central tube communicates with the housing bottom air outlet by extension and short tube.Described extension expansion section is provided with one or three leaf revolving fragments 10 in the top.

Operation principle below in conjunction with three separation of accompanying drawing narration the present invention.The air channel that connects the electric fan air inlet in the dust catcher is connected with dirt cup air outlet 3, starting switch, after the electric fan work, dirt cup inner chamber produces negative pressure, the air that has dust enters dirt cup inner chamber by dirt cup air inlet 1, because the periphery of dirt cup air inlet 1 axis and dirt cup housing 13 is tangent, thereby produce swirling eddy.Owing to being lower than dirt cup air inlet 1, separator air inlet 6 positions have certain drop again, make the certain draught head of generation between two air inlets, therefore after the air that has a dust enters the dirt cup, promptly produce the quick whirlwind of downward spiral, dust is subjected to centrifugal action to be thrown toward perisporium and along fall dust-collecting cavity 2 between dirt cup cup 13 and outer tube 9 of wall rotation.Because the partition effect of cage 7, the dust that falls into dust-collecting cavity 2 are difficult to be subjected to the influence of top spiral air flow and roll again and enter separator air inlet 6.Isolate most dusts.The air of slightly a small amount of thin dirt, the gap 15 in entering by separator screw-like air inlet 6 between pipe 8 and the central tube 4, owing to be subjected to the guide effect of air inlet helical blade 12, entering in the gap 15 slightly on a small quantity carefully, the air of dirt produces spiral air flow equally.Pipe 8 upper end rear screw radiuses increase suddenly in this part air rises to, and blast reduces, and centrifugal force will mix in airborne a small amount of thin dirt and separate, get rid of to outer tube 9 inwalls and fall along the wall rotation supreme in dirt chamber 5.Air after the separation enters extension 14 by central tube 4, because the air after the effect of three leaf flights 10 in the extension 14 separates continues rotation downwards, as the also slightly a small amount of thin dirt of this part air, then when this part air drops to extension 14 expansion sections, the radius of spin increases suddenly, blast reduces, and centrifugal force will mix once more in the thin dirt of airborne minute quantity and separate, and gets rid of to extension 14 expansion section inwalls and along the wall rotation and falls to dirt chamber, bottom, extension 14 expansion sections 16.Air after separating for three times enters motor through short tube 11 and air outlet 3, discharges dust catcher then.
