Definitions

  • the subject of this invention is a new dust exhaust/decontaminating device for palletized goods entering and/or leaving production areas.
  • Said device can be widely used, for example, in the field of pharmaceutical, cosmetic, food and hospital products, and in most of the electronics industry.
  • the object of this invention is to provide a dust exhaust device which eliminates dust particles of a size larger than or equal to 0.3 ⁇ and is especially effective for those larger than 2 ⁇ . Said dust partticles may have settled on the outer surface of the materials, even in the case of wrapped packs. The elimination thereof allows externally dedusted containers, also ready for any subsequent treatment (for example, sterilization), to be sent to the production areasa or into the outside environment.
  • said dust exhaust device to consist of a casing, having at least one door, selectively opened or closed, for introducing the support for the materials to be externally cleaned, a rotating base driven by a motive means, a blower device, a filtering device and a unit for channelling dustfree air into nozzle elements placed along the periphery of said dust exhaust device the nozzle elements being directed at the material to be externally cleaned.
  • a unit is also provided for collecting or aspirating air from inside the casing to send to the pressurizing and filtering system.
  • a casing 10 can be seen provided on two opposite sides with airtight doors 12, selectively opened and closed, for the entry and exit respectively of the supporting unit or pallet 19 for the materials to be cleaned.
  • a base 18 is prearranged, made to rotate at a preset speed by a motor 20.
  • a unit consisting of two fans 14, suitable for sending air to a twin-filter unit 16, is placed at the top.
  • a unit for distributing the clean air is connected to said twin-filter unit.
  • the supply or distribution unit is shown in more detail in fig. 2.
  • an upper distribution channel 28a two lateral distribution channels 28b, placed on two diametrically opposite sides (fig. 3), and a lower distribution unit made up of two channels 28c.
  • a unit for aspirating the air with the dust removed from the pallet 19 can also be seen by referring to figs 2 and 3.
  • the air is returned by means of opening 30a, provided for each channel 30, to the two-fan unit 14 which re-channels the air through the twin-filter unit 16 so that, suitably filtered, it can be recycled.
  • Nozzle in the form of slits in this embodiment, are prearranged in the distribution channels 28a, 28b and 28c. Said nozzles serve to channel pressurized air around the peripheral surface of the support unit to be cleaned, the air being directed for the top through nozzle 22 (fig. 1), for the side through nozzles 23 (fig. 3) and fran the bottom through nozzle 24 (fig. 2).
  • the openings 30a for aspirating the air containing dust removed from the outer surface of the support or pallet 19 are situated in a lower position, that is, at the same level as the rotating base.
  • Fig. 3 represents in cross-section the configuration of the rotating base 18, on which the dashes indicate the overall dimensions of the support or pallet 19, the prearrangement of the lateral channels 30 for collecting the air containing the impurities fran the outer surface of said support also being shown.
  • Fig. 4 shows the configuration at the top of the fans 14 and filters 16.
  • An exemplary nozzle element which acts on the whole top, bottom and lateral surfaces is shown in more detail in fig. 5.
  • An opening with a constant clearance 32 can be seen therein, made in the walls 35 of the supply channel whereon acts a pair of vanes 34.
  • Said vanes are made to slide by suitable and fully known means, so as to selectively regulate the clearance of the opening 36 for supplying the pressurized air.
  • the rotating base 16 rotates at a speed of between 3 and 8 revs/minute.
  • the two centrifugal type direct-aspiration fans 14 have been selected so as to have an air-delivery capacity of 3000 m 3 /h each, with a delivery pressure of at least 180 mm/H 2 O (water column).
  • the filters 16 are of the absolute type, each suitable for allowing 3000 m 3 /h of air to pass at a filtering efficiency of at least 99.997%.
  • the delivery and aspiration channels have a section of 500 mm by 250 mm.
  • the opening 32 in the nozzles is between 15 and 30 mm, while the vanes 34 are regulated so as to set an opening 36 of between 4 and 8 mm.
  • the rate at which the air is emitted from the nozzles is between 30 and 50 m/sec. It is preferable to act on the variable parameters of the device in order to obtain an optimum of air emission rate from the nozzles of about 4Q m/sec.
  • said nozzles prefferably be located at a distance of between 10 and 30 cm fran the outer surface of the pack of goods to be cleaned.
  • Sterilizing lamps 40 for decontaminating may be fitted inside the device, using fully known means.
  • the duration of the dust exhaust/decontaminating cycle with the use of a suitably filtered continuous air jet is set at 1 to 5 minutes.
