Definitions

  • the present invention relates to a mobile suction cleaning device, intended for the maintenance of towns and in particular of water nets and sidewalks, comprising a suction mouth connected by a flexible tube to a mechanical dust separation device. and waste entrained by the flow of aspirated air, and suction means.
  • This process finds its main application in fixed or mobile suction cleaning devices intended for the maintenance of cities, warehouses or private grounds, for clearing leaves, for cleaning beaches and railways, eliminating waste industrial of a work table of a grinding, sanding and welding machine and the capture of shavings, sawdust and brazing.
  • baffles By said baffles, the air flow sucked in is subjected to sudden changes in direction which cause the particles to stop and be eliminated by inertia. dust with a diameter greater than 50 microns.
  • a cyclone device has the disadvantage that it cannot be used to collect waste consisting of a sticky thixotropic mass such as mud or animal debris. Such waste could, in fact, by adhering to the circular wall of the cyclone tank, quickly obstruct said device.
  • the present invention provides a mechanical separation device which gives the cleaning machines increased maneuverability allowing them to be used on the sidewalk and to access the surrounding area, even when cars are parked there.
  • the proposed mechanical separation device allows this cleaning machine to collect any waste, debris and litter without inconvenience.
  • the invention relates to a mobile cleaning device not suction intended for the maintenance of cities and in particular of water nets, and sidewalks, comprising a suction mouth connected by a flexible tube to a mechanical separation device dust and waste caused by the flow of sucked air, and suction means, this device being essentially characterized in that the aforementioned mechanical separation device is provided with at least one removable disposable bag, intended to receive and contain the waste.
  • the sedimentation chamber intended for the preliminary separation of sedimentation intended for the preliminary separation by gravity and possibly by inertia of the dusts and the cyclone intended to separate the dusts by centrifugal force are arranged in the same container. .
  • the invention also relates to a process implemented in the machine described above, for mechanically separating waste, dust and / or particles of any solid or liquid material of different densities or particle sizes from the entraining fluid, characterized in that we use successively the action of gravity, inertia and possibly a centrifugal force field to separate the dust and waste that we receive in a removable bag, which we remove filled with the device, which we tie and that we deposit along the road.
  • the dust is separated by gravity, then inertia using baffles, before treating the flow of air sucked in by centrifugal force in a cyclone or a centrifugal elutriator.
  • a vacuum cleaning apparatus designated as a whole by the reference notation 1 comprises a mechanical separation device composed of a sedimentation chamber 2 combined with a cyclone 3.
  • a flow of aspirated air loaded with dust, debris and any waste such as paper, tree leaves, sand, pieces of wood, cigarette butts and animal debris, rushes into the suction mouth 4 and flows with turbulence in the direction of arrow X along the conduit suction 5 advantageously consisting of a flexible tube which ends in said sedimentation chamber 2 in which the flow speed of the air flow sucked or the entraining fluid suddenly decreases.
  • the waste and dust are deposited at the bottom of the sedimentation chamber, possibly lined with a bag 6 intended to receive the waste in order to facilitate unloading.
  • the vertical component of the flow velocity of the flow in this first helical phase, which is directed downward, is favorable to the mechanical separation and the evacuation of the dust waste towards the base 11 of the cyclone 3.
  • the mechanical separation of the waste in the sedimentation chamber 2 can be improved by the judicious placement of baffles, not shown, preferably in the vicinity of the inlet and the outlet of the sedimentation chamber 2. These baffles involve the waste inertia. A judicious arrangement of baffles makes it possible to superimpose the inertia of the heaviest waste on the force of gravity so as to further promote the mechanical separation of dust.
  • the sedimentation chamber 2 intended for preliminary separation by gravity and the cyclone 3 are formed in the same container, the latter is advantageously made up as illustrated in FIGS. 3 to 5 of a removable cylindrical body 13 provided with a cover 14 which has a supply orifice 15 for the flow of aspirated air and a first cylindrical jacket 16 which surrounds a second advantageously frustoconical jacket 17 concentric with the first jacket and along which is introduced tangentially and at a high speed, a secondary air current intended to communicate with the sucked air flow, a vortex movement, the outlet orifice 9 being formed concentrically all around the aforesaid jacket, outside thereof and at a certain distance from the side wall of the cylindrical body, protected by a 9 'filter.
  • the mechanical separation device is advantageously mounted on a light self-propelled vehicle 18, equipped with a hydraulic motor 19 so that it can be driven, that is to say both directed and controlled only using a pair of foot pedals 20.
  • the driver 21 thus keeps his hands free to direct a flexible suction tube 5, for example between parked cars and the edge 22 of the sidewalk.
  • a fixed suction ramp is mounted obliquely under the vehicle over the entire width of the latter.
  • This suction ramp 23 is advantageously arranged obliquely and equipped with a transverse roller 24 possibly with side brushes not shown.
  • Examples 1 and 2 relate to cleaning devices intended for the roads of a city.
  • a municipal vacuum cleaner according to the invention intended for cleaning the roads of a city and designated as a whole by the reference notation 18 consists of a cyclone suction and cleaning device, as described above, mounted on a free-standing self-propelled carriage, with hydraulic transmission and steering device.
  • Each of the stilling chambers 2, connected to at least one cyclone 3 is arranged with the suction turbine 25 and the drive motor 26 behind the seat 27 of the driver 21.
  • the suction manifold flexible 5 pivotally mounted around a vertical axis 28 is controlled, for example manually, by the conductor 21.
  • the lower body 11 of the sedimentation chamber 2 and of each of the cyclones 3 consists of a removable cylindrical frame 29.
  • Each of these bodies 11 is covered with a trash bag 6 intended to receive and contain the waste.
  • the bag 6 is held in place and kept open despite the suction suction, using a frame 29 consisting of a series of vertical rods, shaped in an L shape and arranged in the manner of the generators of a cylinder. Said bars are stabilized on the upper face by a flat ring so that the bottom is free.
  • the trash bag 6 arranged around the cylinder is fixed by a tape clip 30.
  • the driver To remove the waste from the hopper, the driver must stop the suction pipe, loosen the tape clip 30 and turn the cylinder towards him. It then lifts the cover and the fixing cylinder using a support slide so as to be able to remove the bag 6 containing the waste consisting for example of paper, animal debris, gravel, sand, tree leaves , various rubbish possibly wet.
  • the amount of garbage that can be harvested also depends on their compaction.
  • the filled bags that are removed from the cleaning device are tied up and placed along the road or on a trailer.
  • the inner body made up of L-shaped bars is optionally cleaned using a flexible suction hose before a new bag 6 is put in place.
  • the cleaning apparatus is provided at its front part with a device for collecting animal debris, equipped with a rotating brush. This device is controlled remotely from the driver's cabin. Most of the animal debris is collected by suction while the last traces are removed by brushing.
  • This mechanical separation device can be mounted on a possibly self-propelled carriage guided by hand. by the steering handle 31. There is optionally provided on the side a suction mouth 4 intended to clean the roadsides and the curbs. This mouth 4 is fixed using a flexible conduit 5. ( Figures 3 to 5).
  • the suction device can consist of an ejector 32 supplied with pressurized air 33 coming from a compressor not shown.
  • the ejected air is led into a cyclone where it is freed of fine dust.
