Definitions

  • This invention relates to dust extractors, and in particular to dust extractors which incorporate cyclone separators.
  • Cyclone separators have been known for many years. A large proportion of the known cyclone separators use a tangential input which causes an air flow to rotate around the interior of a cylindrical housing. The rotation of the air causes a "cyclone" action, which centrifugally throws heavier particles to the outside. The heavier particles are allowed to settle to the bottom of the separator whilst the cleaner air exits through the centre of the top of the separator.
  • a cyclone dust extractor comprising a housing defining a first cyclone separator and a second cyclone separator in series, a fan for producing cyclones within the cyclone separators and a motor for driving the fan, wherein at least one of the cyclone separators has an inlet portion and an outlet portion which are separated by a wall.
  • the outlet portion of the at least one cyclone separator acts as a third cyclone separator.
  • the outlet portion of the at least one cyclone separator is preferably reverse rifled to assist in extracting dust from the air flow.
  • the end of the wall separating the inlet portion and the outlet portion of the at least one cyclone separator preferably includes a diffuser (or baffle) for assisting in separating the inlet cyclone from the outlet cyclone. More particularly, the diffuser can assist in directing the inlet flow away from the outlet flow.
  • the wall between the inlet portion and the outlet portion of the at least one cyclone separator defines an inlet passageway with an outer wall and an outlet passageway with an inner wall which both have cross-sectional areas which reduce on progressing along the passageways.
  • the inner wall of the outlet portion of the at least one cyclone separator acts as an outer wall for the second cyclone separator.
  • a dust collector may be situated between the inlet portion and the outlet portion of the first cyclone separator. Further, a collar is preferably provided in the dust collector to help discharge dust particles carried by the cyclone.
  • the dust collector preferably can be separated from the housing to discharge dust particles collected in the chamber or chambers of the collector.
  • the second cyclone separator preferably comprises four stages, a first stage accelerating the cyclone, a second stage decelerating the cyclone, a third stage accelerating the cyclone and a fourth stage decelerating the cyclone.
  • the fourth stage of the second cyclone separator may be situated within the dust collector. As a result, dust extracted by the second cyclone separator can be discharged from the dust extractor at the same time as that from the first cyclone separator.
  • the second cyclone separator preferably includes a frusto-conical outlet passageway communicating with the fan.
  • the broader end of the frusto-conical outlet is adjacent the fan, thereby causing dust to be deposited in the cyclone separator before the air of the cyclone reaches the fan.
  • the housing is preferably provided with a tangential inlet port communicating with the first cyclone separator.
  • the extractor may be portable. Further, the extractor may include a belt clip for attaching the extractor to a belt of a user.
  • a dust extractor according to the present invention may be battery operated.
  • a cyclone dust extractor 1 comprises a housing 3 having an inlet 5 and an outlet 7, a motor 9 for driving a centrifugal fan 11, a dust collector 13 and a belt clip 15.
  • the housing 3 includes a battery compartment 17 which accommodates a battery (not shown) for driving the motor 9 via switch gear 19.
  • the portable cyclone dust extractor 1 can be clipped onto a user's belt by means of the belt clip 15 and the motor 9 can be energised using the switch gear 19 to drive the centrifugal fan 11 to suck dust and debris into the dust extractor 1 via a hose 21 and the inlet 5.
  • the dust and debris is then separated from the air flow by means of cyclone separators within the housing 3 which will be described in more detail hereinafter.
  • the dust collector 13 When dust and debris has been separated from the air flow, it accumulates in the dust collector 13. Since the dust collector 13 can be separated from the housing 3, collected dust can be emptied from the collector 13 and deposited in any suitable waste disposal site. The collector 13 can then be reattached to the housing 3 for further use of the dust extractor 1.
  • the inlet 5 of the dust extractor 1 communicates with a first cyclone separator 23 and the outlet 7 communicates with a second cyclone separator 25 via the centrifugal fan 11.
  • Each of the cyclone separators 23,25 has a respective inlet portion 27,29 and an outlet portion 31,33.
  • a wall 35 separates the inlet portion 27 from the outlet portion 31 along virtually the complete length of the two portions 27,31.
  • a frusto-conical wall 37 of the second cyclone separator 25 extends only part way into the second cyclone separator 25 such that the inlet 29 and outlet 33 portions of the separator 25 are not completely separated.
  • the first cyclone separator 23 includes a dividing wall 35 between the inlet portion 27 and the outlet portion 31 of the separator 23.
  • This wall 35 forms a first converging passageway 39 with the housing wall 41 as shown in Figure 3.
  • the air rotates around the channel 39 within the housing 3 and proceeds down the passageway to the narrower end. The air therefore accelerates and, on exiting the end of the passageway 39 into a collection chamber 43, is immediately decelerated, thereby depositing large dust and debris particles in the collection chamber 43 of the dust collector 13.
  • the wall 35 carries a diffuser 45 which directs the cyclonic air flow away from the outlet portion 31.
  • a further collar 47 is provided in the collection chamber 43 against which large dust and debris particles collide, thereby assisting in removing the dust and debris from the air flow and depositing it in the collection chamber 43.
  • the outlet portion 31 of the first cyclone separator 23 carries the rotating air flow from the collection chamber 43 upwards towards the top of the housing 3. As the air rises, the passageway narrows, thereby accelerating the air flow.
  • the wall 35 acts as an outer wall of the second portion 31, an inner wall 49 of which diverges and approaches the separating wall 35.
  • reverse rifling may be formed on the walls 35,49 within the outlet portion 31 to assist in this process.
  • this outlet portion 31 of the first cyclone separator 23 acts as a third cyclone separator.
  • the rotating air flow passes through an opening 51 and into the second cyclone separator 25.
  • the air descends down the inside of the converging wall 49 and, on passing the end of the frusto-conical wall 37, decelerates which tends to cause further dust particles to drop out of the cyclone.
  • This deceleration is caused by the sudden removal, as seen by the air, of the frusto-conical wall 37.
  • the air travels further down the second separator 25 constrained by converging wall 49. This converging wall 49 thus causes an acceleration of the air.
  • the air flow is accelerated due to the tapering of the converging wall 49, as described above.
  • the cyclone is allowed to expand, thereby decelerating and releasing further dust particles.
  • Four stages therefore exist in the second cyclone separator 25, namely acceleration, followed by deceleration, followed by acceleration and subsequent deceleration of the cyclone.
  • the collector 13 can be disconnected from the housing 3 to be emptied. On re-engagement of the collector 13 with the housing 3, the cyclone dust extractor 1 is once again ready for action.
  • the cyclone dust extractor 1 is particularly efficient and, consequently, suitable for use with a battery pack rather than a mains power source.
