Definitions

  • the present invention relates to a vehicle with a sweeper, in particular for collecting dusty material.
  • a cleaning device which is particularly suitable for cleaning streets and runways at airports.
  • This device has a sensor with two sensor nozzles, the mutual position of which is rigid.
  • the coarse fractions taken up are discharged into a cuboid chamber, in which, as the deposited material rises, the air passing through has increasing speeds and therefore not only does the air resistance in the chamber increase, but in particular the degree of separation deteriorates. This condition cannot be improved even by downstream screens and extraction of a partial air flow with recirculation into the chamber.
  • Several, extremely complex, horizontally arranged, parallel centrifugal separators can not take advantage of the weight of the particles for the final separation of air and particles.
  • a suction device for dust, chips, rubbish and other waste has a sensor in the form of a laterally rounded cuboid chamber, from the center of which a slot-shaped suction nozzle with a line leads to a first centrifugal separator.
  • a slot blow nozzle opens out of the lid into the chamber.
  • a blower between the blowing nozzles and the cyclone, whereby from the nozzle line - i.e. from the pressure line from the blower - a branch line with a fine separator and control valve branches off.
  • this suction device is very simple, but it is hardly sufficient in terms of its effectiveness for fine dust; because there is only one nozzle in the sensor.
  • the air distribution in the recirculating air and exhaust air is too immobile, since the recirculating air is only indirect and not inevitable - e.g. by means of another fan - is changeable.
  • This suction device is therefore unsuitable because it is not effective enough to solve the problem at hand (FR-PS 1 057 157)
  • the object of the present invention is to provide a sweeper, in particular for collecting metal dusts, which is simple in construction, has low pressure losses in the transport air due to good line routing, can be easily adapted to the specific dusts and can be accommodated as an assembly in the most confined space.
  • this task can be carried out with the vehicle according to the invention with a sweeper.
  • Fig. 1 shows the circuit diagram of a system 1 for receiving aluminum dust, with the pneumatic and the separation system.
  • a main blower 3 is provided with a pressure port 4, which is divided into a main duct 6 and a secondary duct 7.
  • the conveying air is divided by means of a flap 8 which can be pivoted about the axis 5 and which can be adjusted manually via a linkage or by means of a servomotor.
  • the main channel 6 opens into a main mouthpiece 9 and supplies a side ring nozzle 10 - there may also be several nozzles extending over at least part of the circumference - with compressed air which blows the dust present against the center of the main mouthpiece 9.
  • a main pipe 12 with a suction nozzle 13 (arranged in the middle or off-center) sucks off the air laden with aluminum dust.
  • a secondary nozzle 15 is provided with a funnel 16 and a suction channel 19, which is designed to be movable, for example as a tube.
  • the suction duct 17 and the main suction pipe 12 merge into a common duct 19, an adjustment flap 20 being arranged in the union in order to make the air quantities correspondingly adjustable.
  • the community channel 19 continues in a cyclone inlet piece 22. In this there is a rotating, for example motor-driven, separation paddle wheel 23.
  • the coarse particles are emptied through the channel 27, while the fine particles which are separated out in the multiclon are collected in the collecting bunker 26 and discharged from there.
  • the three cyclones are in a collecting bunker 28.
  • the central suction pipes 30, 31 and 32 of the cyclones 24, 25 and 26 open into a cyclone discharge piece 34 which merges into a blower suction line 35 which leads into the suction port of the blower 3.
  • the secondary duct 7 leads to a bag filter 38 with a chamber 39 and an outlet 40.
  • filter bags 41 are known to be hung next to one another and, if appropriate, one behind the other.
  • the resulting fine powder is discharged at the outlet 40, while the exhaust air leads through an exhaust air duct 43 into an exhaust air blower 45, which blows the air, which has been practically cleaned of aluminum dust, into the atmosphere.
  • the bag filter 38 no further details are disclosed about the bag filter 38, such as, for example, the automatic cleaning by shaking the filter bags, their replacement, the use of the corresponding tissue, etc. - since these are part of the prior art.
  • FIG. 5 shows a four-wheel vehicle 50 with a driver's cab 52 and a bridge 53 on which the blower 3, the main mouthpiece 9 and the secondary nozzle 15 can be seen.
  • the collecting bunker 28 with the cyclones is shown schematically, as well as the bag filter 38 with the filter bags inside, the entire four-wheel vehicle 50 with the driver's cab 52 and the bridge 53.
  • a drive group 55 which can also be seen in FIGS. 2-4, drawn with auxiliary units 57.
  • the secondary nozzle 15 is due to the movable suction channel 17 - e.g. in the form of a tube - arranged to be displaceable, the normal working position in FIG. 5 with a solid line, for sweeping niches with dashed lines and the cleaning position of raised heels, e.g. Oven borders are drawn with dash-dotted lines.
  • a sweeper built on this principle according to FIGS. 1-5 is capable of picking up the finest aluminum dust, separating it and thus trapping it without blowing it out into the atmosphere at another point.
  • Fine dust In addition to aluminum dust, other fine dusts such as Cement and the like. Fine dust can be obtained.
