Definitions

  • This invention relates to an automatic water transfer installation for the equipment used to wash the refuse bodies.
  • the collection of the refuses is carried out by means of refuse bodies which are periodically emptied by special vehicles which carry out automatically the transfer of the refuses from the refuse body to the loading space of the vehicle.
  • Said vehicles are generally formed, in the portion inherent to their function, by a caisson,mounted on the chassis of the vehicle, which is divided into sections containing both the washing liquid and the liquid pumping systems and, in the rear portion, by a washing and washing water collecting chamber and by a refuse body lifting and overturning mechanism disposed within said washing chamber.
  • a disadvantage of the known refuse body washers consists in that the transfer of the water from the washing chamber to the reservoir is carried our by means of centrifugal impeller pumps, of the self-priming or other type, which have the disadvantage of easily becoming clogged because of the continuous passage of water with the solid bodies suspended therein.
  • the object of the device according to the invention is to provide a mechanism of easy maintenance and non-critical use by means of which it will be possible to avoid the disadvantages of delicacy and assiduous maintenance due to the transfer methods described above, and which, in addition, will attain the object of completely discharging the water which collects on the bottom of the washing chamber.
  • the invention proposes to provide an automatic water transfer installation to be used for the washing of refuse collecting bodies, mounted on a motor vehicle having, in its front portion, a reservoir and, in its rear portion, a washing chamber for weshing the refuse bodies, said reservoir being divided into compartments for recovering the washing water and collecting the clean water intended to be used for the washing, characterized in that the installation is provided with a pump intended to create a vacuum in the interior of the washing water recovery compartment and a vacuostat operatively connected to said vacuum pump and to a floodgate inserted along a connection pipe between the water recovery compartment and the washing chamber, interconnected in such a manner that the vacuostat actuates the pump and closes the floodgate when the atmospheric pressure is attained in the recovery compartment, and subsequently closes the pump and opens the floodgate when the pre-established vacuum is attained in the recovery compartment.
  • the reservoir 4 mounted on the chassis 1 is divided into three compartments: two side compartments 5 and 7 for clean water and a central compartment 6 for the recovery of the water used for the washing.
  • a sucking conduit 9 which extends to the vacuum pump 3; situated above said compartment 6 is a maximum safety valve 10 for the vacuum.
  • a pneumatically controlled spherical cock 11 which regulates the inflow of the washing water, coming from the washing chamber 13, through the conduit 12, into the compartment 6.
  • An end 14 of the conduit 12 debouches into the compartment 6, and the other end 15 grazes the bottom of the washing chamber 13; the washing water is filtered in respect of the more coarse deposits by the filtering grid disposed within the chamber 13.
  • the washing chamber has a lower port 16 and an upper port 17, hinged in its rear portion.
  • a switch 18 Disposed adjacent the hinge of port 17 is a switch 18 connected to the floodgage 11.
  • control station 19 Situated on the compartment 7 is a control station 19 into which there is inserted a double calibration (minimum and maximum)vacuostat 20, also connected to the floodgate 11.
  • Said compartment 6 is connected to the washing chamber 13 through the stainless steel pipe 12 intercepted by the spherical floodgage 11 which, during the development of the vacuum, obviously remains closed.
  • the switch 18 is closed by simply opening the upper port 17, the switch 18 is closed; at this point, the electric consent signal may prosecute and, by means of the pneumatic electric valve, the spherical cock 11 is opened, thus starting the transfer of the washing water which is sucked into the compartment 6.
  • the pressure within the compartment 6 begins to increase till, after the minimum calibration of the vacuostat 20 has been attained, the vacuum has been re-established and the cycle begins again.
  • This system in addition to the advantages described hereinabove, has the advantages of being completely automatic, since it is independent from the stages of washing of the refuse bodies, and above all absolutely safe since it depends only on the calibrations set on the vacuostat.
