Abstract
The utility model relates to a static dedusting vacuum cleaner consisting of a filter screen, a gas aspirator, a static dedusting channel and a high voltage generating circuit. High voltage is imposed between two electrodes of the static dedusting channel. After air is absorbed through the filter screen by the gas aspirator of the vacuum cleaner, large particles are retained in the filter screen by the filter screen, air with smaller dust particles passes through the static dedusting channel, and the dust particles in the air are then absorbed by the intedigitated electrodes, thus filtering and eliminating dust.
Description
Technical field
The utility model relates to a kind of dust catcher that electrostatic precipitation is arranged, and can adsorb the dust in air that the dust catcher screen pack is discharged, and makes the air of discharge not have tiny dust.
Background technology
At present, known dust catcher utilizes centrifugal or the axial-flow type lift pump, forms a negative pressuren zone in dust catcher, makes the air of outside be able to enter into dust catcher by suction pipe.When air entered dust catcher, air-flow was brought some small-sized objects in the screen pack of dust catcher into.A screen pack is installed in dust catcher, the object detention that enters dust catcher in dust catcher, is excluded outside the dust catcher through the air of screen pack.Present many dust catchers also filtered with finer and close screen pack before air is discharged dust catcher except screen pack is arranged again, however, still had littler dust to get back in the air.
Summary of the invention
In order to overcome existing dust catcher dust is filtered halfway deficiency, the utility model provides a kind of dust catcher that electrostatic precipitation is arranged, and can will stay in the dust catcher by the dust of screen pack, can not make the contamination by dust air, has purified the air that dust catcher is discharged.
The utility model solves its technical scheme: screen pack, air-breathing unit, electrostatic precipitation passage and high voltage generation circuit order are in succession, the electrostatic precipitation passage is made up of some electrodes of inserting finger-type that are, and electrode is added with the positive negative high-voltage of high voltage generation circuit respectively.After air is by the lift pump inspiration screen pack of dust catcher, by screen pack larger particles is stayed in the screen pack, and the air that has less dust granule passes through the electrostatic precipitation passage again, by the electrode of inserting finger-type dust in air is adsorbed, thereby plays filtering to dust.
The beneficial effects of the utility model are that dust catcher no longer includes little dust and enters into space on every side together in company with air when sucking object discharge air, has purified the air of environment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structure chart that adopts the axial-flow type lift pump, and Fig. 2 is the structure chart that adopts centrifugal lift pump.Among the figure, 1. dust catcher lid, 2. rubber seal,, 3. screen pack, 4. lift pump blade, 5. electrode base, 6. dust catcher air inlet, 7. motor, 8. venthole, 9. electrode, 10. electrode, 11. steam vents, 12. pedestals.
The specific embodiment
In Fig. 1 or Fig. 2, motor 7 drives lift pump blade 4 and rotates.For the axial-flow type lift pump, air is along the blade axial flow, and concerning centrifugal lift pump, air-flow direction is with axially perpendicular, and air flows out around blade.Blade is when rotating, and air is discharged the pressure height of direction, and the pressure of approach axis is low, forms a negative pressuren zone at the air approach axis, and the pressure reduction of negative pressuren zone and dust catcher external pressure makes air enter dust catcher along air intake duct.Owing to screen pack 3 is arranged at negative pressuren zone, stopped the object of appearance and size greater than filter mesh, make it to stay in the net.Air by screen pack enters the electrostatic precipitation passage through venthole 8.Electrode 9 and electrode 10 are concentric circles and insert finger-type, are added with high voltage between electrode 9 and electrode 10.Air being in the electrostatic precipitation passage inserted tortuous flowing between finger electrodes, and it is adsorbed that dust in air will be added with high-tension electrode, thus filtering the airborne minute dust of discharging by steam vent 11.
Can use the civil power of 50Hz, 220V, provide electrostatic precipitation desired high voltage through voltage doubling rectifing circuit, also can boost, provide electrostatic precipitation desired high voltage, also can provide electrostatic precipitation desired high voltage with special high voltage generation circuit through over commutation with transformer.With lead high voltage generation circuit is linked to each other with electrode.
Claims (2)
1. the dust catcher that electrostatic precipitation is arranged has screen pack, air-breathing unit, electrostatic precipitation passage and high voltage generation circuit order in succession, and it is characterized in that: the electrostatic precipitation passage adds positive and negative high-tension electrode respectively by several and constitutes.
2. dust catcher according to claim 1 is characterized in that: add positive and negative high-tension electrode and be the slotting finger-type of concentric circles.
