Definitions

  • the present invention concerns a device for cleaning streets, squares, fields and the like, in particular a vehicle on which is provided a suction device.
  • a device for cleaning streets and the like which is provided with a suction device which consists of a housing in which is provided a chamber with an inlet and an outlet.
  • the above-mentioned chamber is divided in two compartments by means of a fine-meshed net, whereby the inlet opens in a first compartment of the chamber and the outlet is connected to the second compartment of the chamber.
  • this suction device In the outlet of this suction device is provided a fan which makes it possible to create an underpressure in the chamber, whereas the inlet is provided with a nonreturn valve which can be only opened towards the inside of the chamber.
  • the above-mentioned fan When operational, the above-mentioned fan is driven, such that an underpressure is created in the chamber and as a result of which the non-return valve opens, such that waste from the street or the like is sucked into the chamber via the inlet.
  • the air flow through the chamber will be less powerful than the one through the inlet, such that relatively heavy waste is removed from the air flow by means of the force of gravity. Light waste is retained in the chamber thanks to the above- mentioned net, through which the air flow streams to the outlet and leaves the chamber.
  • a disadvantage of such a known device is that the above- mentioned net in .
  • the suction device is clogged up relatively quickly, especially when a lot of paper or plastic packings and the like are sucked in.
  • the waste has to be manually removed from the net, and the waste which has been removed from the net has to be taken . out of the chamber, in order to prevent it from being sucked out of the chamber against the net again.
  • Another disadvantage of the known device is that the air leaves the suction device untreated, whereby particles of dust are inevitably ejected, which is not only unpleasant among others for the operator of the device, but which is also environmentally harmful.
  • the aim of the present invention is to remedy one or several of the above-mentioned and other disadvantages.
  • the invention concerns a device for cleaning streets, squares, fields or the like which mainly consists of a mobile frame on which is provided at least a suction device which consists of a housing with an inlet for waste and a drain in which are provided means for sucking in air, whereby a partition is provided in the housing which divides the space in the housing in two compartments, namely a first compartment in which the inlet opens and a second compartment onto which the drain is connected and whereby the partition is at least partly made of a net, characterised in that in the above-mentioned first compartment are provided means for cleaning the net.
  • An advantage of a device according to the invention is that it can efficiently suck up waste, such as paper and plastic packings, without its operation being disturbed as the waste obstructs the air flow which is required to suck up the waste.
  • means are provided in the first compartment which divide the first compartment in two sections, namely a first section in which the above-mentioned inlet opens and which is partly confined by the above-mentioned net, and a second section which is confined by a plate, such that this second section is closed off from the first section and from the second compartment in the suction device.
  • An advantage of this preferred embodiment is that the waste, after it has been sucked up from the air flow, is removed and stored in the section which is confined by the plate, where it cannot be sucked in against the above-mentioned net again, such that the suction force of the device stays guaranteed and such that a device according to the invention allows for an efficient cleaning.
  • an air washer to suck in air from the chamber.
  • Such an air washer makes it possible to remove dust particles, which are sucked in while cleaning, from the air flow before ejecting the sucked-in air, such that relatively pure air is ejected.
