Definitions

  • This invention relates to a suction cleaner.
  • the invention is particularly concerned with a suction cleaner of the type described in British patent number GB 2 198 930B, although it is not particularly limited to such a machine.
  • the invention provides a suction cleaner provided with means for receiving air and entrained detritus and directing it along an external downward helical path to a container, where particles > 50 microns can be trapped.
  • the cleaner can be a movable cleaner such as an industrial vacuum cleaner, or can be a fixed apparatus drawing detritus such as wood chips or shavings from a machine or the like.
  • the formation is such as to allow the air, after it reaches the bottom of its path to rise in an ascending helical path within the outer helical path.
  • the air flow is such adjacent the lower end of the two helical paths that at such ends the velocity of the air drops so as to allow entrained particles to drop therefrom into the waste receptacle.
  • an upper part of the said means is arranged to direct the flow to an annular lip at which there is a velocity drop causing larger items to drop from the flow.
  • the annular lip can allow low velocity air to flow upwards towards the filter.
  • the said means can comprise a cyclone-creating body wherein incoming air enters and is directed by baffles or the like downwardly in a helical manner.
  • the casing can have an inwardly converging frusto-conical wall, or parallel sides.
  • the separator arrangement (10) shown in figure 1 can be disposed in the region of the chamber (32) and container (36) shown in figure 2 of British patent 2 198 930B. However, it is also to be appreciated that they can be disposed in any suction cleaner or apparatus of any other design.
  • the arrangement (10) has an upper chamber (11) and a lower chamber (12).
  • the upper chamber (11) has an outer wall whose main peripheral portions are constituted by primary filter elements (13).
  • Filter elements (13) are designed to be replaced as little as possible and means can be provided for cleaning them by air flow reversal as described in the aforesaid patent.
  • such filter elements (13) are often impacted by flying particle, and so blocked rapidly by embedment of dust particles and by pieces of paper, and by other waste materials.
  • a cyclone body (14) is provided within but spaced from the filter elements (13).
  • the cyclone body (14) is made from sheet metal and has an a inlet (15) along which air flow from a suction head (not shown) is delivered at speeds which may be as high as 51m per second. From the inlet (15) the air flow enters a circular chamber (16) having a closed top (17) within which the air it must circulate.
  • the outer wall of the chamber (16) is wall (18) of the body (14).
  • a circular air flow is caused to develop under pressure from the inlet (15) and is compelled to orbit within the chamber (16). This orbital flow can be enhanced by use of baffles and/or the like.
  • the circular flow is directed downwardly and attains, generally the form of a helix (19).
  • the outer wall (17) is connected to the upper end of an inverted frusto-conical accelerator wall (20) which has a lower rim (21). Entrained matter travels down the helix (19).
  • the waste receptacle (22) which can be a bin liner within a casing (23) and which forms the lower chamber (12)
  • the air in the helix cannot travel further downwards and therefore is caused to travel upwardly making an outer helical path (24) entering the upper chamber (11) through an annulus (25) located between the rim (21) and the casing (23).
  • the distance travelled by the air in the inner helix is far less greater than that by the air in the outer helix and therefore this leads to a very obvious difference in velocity between the two.
  • the descending air has a high velocity as it is travelling in a smaller helix whilst the ascending air has a low velocity as it is travelling up a helix of larger diameter.
  • This drop in velocity is significant in that it is very helpful in allowing or causing entrained detritus to drop out of the air stream and compact in the bottom of the receptacle (22). Only the smaller dust, particles and pieces of material ascends the outer helix (24).
  • the first pre-filter is an open metal mesh or perforated plate in the form of an inverted channel (28) secured to the rim (16) and a filter support casing (29).
  • the purpose of the pre-filter is to trap relatively light but relatively large surface area objects, such as pieces of paper.
  • the second pre-filter is in the form of a filter diffuser comprising a ring of blades (30) set at an angle of 45° inclined towards the direction of air flow (24).
  • the function of the blades (30) is to change the direction of the air flow and thus reduce the velocity of the upwardly directed rotating air flow allowing only particles of ⁇ 50 microns to pass to the primary filters (13) for filtration to ⁇ 6 microns to atmosphere.
  • a third pre-filter (33) consisting of a perforated plate can also be provided upstream of the primary filters (13) if required.
  • the provision of the separating arrangement (10) within the suction cleaner produces a suction cleaner of greatly improved efficiency whose filters are longer lasting and which need cleaning by reverse air flow at longer intervals. Further, as the entrained material is driven down into the second chamber (12) by the air flow there is a better compaction of waste in the bottom of the container and therefore better utilisation of the container volume.
  • the arrangement can have baffles or and the like to encourage helical air flow.
  • the cyclone body (14) could form the wall of the chamber.
  • the accelerator wall (20) could be dispensed with, all air flow taking place via the conduit (18) through an appropriate filter. Even with the cyclone body (14) within the chamber (11) the accelerator wall (20) can be dispensed with if desired.
  • the arrangement of the invention is suitable for use not only in mobile or portable suction cleaners, but also in other suction cleaning apparatus, for example static apparatus arranged to extract wood particles/dust from machines or like sources.
  • the first mesh type pre-filter (28) can be a cylinder (31) as shown in figure 3, of slightly smaller diameter than the casing (23), sealed at the rim (16) and at its base (32).
  • the cylinder (31) is removed from the casing (23), when the receptacle (22) is taken out for emptying.
  • the space around the rim (21) will be restricted, causing an increase in pressure in the chamber (16).
  • a pressure differential will thus be created between the inside and outside of the chamber (16). The pressure difference can be used to operate an electrical switch to indicate to the operator that the receptacle requires emptying, or to switch the machine off.
