Definitions

  • the present invention relates to a sludge sucker according to the preamble of claim 1.
  • a device for aspirating liquids which alternatively has either a float circuit for opening and closing of valves or a timer or a timer.
  • a ventilation valve and a suction valve should be opened or closed.
  • the two switching variants for the valves are not able to additionally perform a control function of certain levels, such that a fully automatic emptying is achieved during operation.
  • the object of the present invention is therefore to provide a sludge suction with which a fully automatic emptying can be performed during a Schlammabsaugvorgang.
  • the device can be converted easily as a conventional wet vacuum.
  • An inventive sludge suction device 1 comprises a housing 1.1, to which a connection 1.2 for a suction element 3 and a connection 1.3 for a discharge element 5 is formed.
  • the housing 1.1 is also formed in its bottom, upper portion as a cover 1.4, which is releasably secured to the lower housing 1.1.
  • the housing 1.1 On the bottom side, the housing 1.1 is provided with a foot element 1.5.
  • the interior of the housing 1.1 is formed in its central region as a receptacle 1.6 for mud and water or materials of similar consistency.
  • the port 1.2 is located in the upper part of the receptacle 1.6 and the port 1.3 is located in the lower part of the receptacle 1.6, preferably the port 1.2 diametrically opposite one another.
  • a motor 1.7 preferably an electric motor, arranged, which is a well-known suction device 1.8, such.
  • B an air-pulling wing element, drives. During the drive air is sucked from the receptacle 1.6 and discharged through openings in the upper housing area to the outside. This creates a negative pressure in the receptacle 1.6 and in the suction element 3.
  • the motor 1.7 is connected to an electrical circuit 1.9.
  • the electrical circuit 1.9 is located near the intended maximum filling level limit of the receiving container 1.6 in a suction opening 1.10 of the suction device 1.8.
  • a guide housing 5 is formed for a float 7.
  • the float 7 can move in the guide housing along a longitudinal axis of the housing 1.1 and, like the electrical circuit 1.9, the suction device 1.8 and the motor 1.7 arranged concentrically to this. In other embodiments, a concentric arrangement need not necessarily be provided.
  • the float 7 has on a Bodenfemen, upper side of a permanent magnet 7.1. With increasing filling of the receiving container 1.6, the float 7 is moved in the guide housing 5 along the longitudinal axis upwards. Shortly before reaching the maximum level limit of the permanent magnet acts on the 7.1 in the suction opening 1.10 opposite electrical circuit 1.9 and closes it. As a result, the engine 1.7 is turned off. When the maximum level limit is reached, the float 7 also closes the suction opening 1.10.
  • the electrical circuit 1.9 is preferably a reed circuit in the present embodiment. In other embodiments, however, other switches and switching systems may be used.
  • the electric circuit 1.9 is connected to a timer (not shown), which can be set so that the motor 1.7 is automatically turned on again after the receiving container has been completely emptied 1.6 via the drain element 5.
  • the time required for complete emptying depends on the volume to be emptied and can be predetermined.
  • the drain member 5 is releasably secured to the port 1.3 in a generally known manner and comprises at its free end 5.1 a vacuum valve 5.2.
  • the drain member 5 is also a hose or a pipe.
  • the mode of operation is now as follows:
  • the suction element 3 hangs with a suction nozzle 3.1 in the water or another liquid fluid.
  • By starting the engine 1.7 starts a suction.
  • About the proboscis, for example, mud from the pond bottom of a pond through the suction element 3 and the suction opening 1.10 is sucked into the receptacle 1.6.
  • the receptacle 1.6 and the drain element 5 to the vacuum valve 5.2 slowly fill with mud.
  • the vacuum valve 5.2 is closed because of the prevailing negative pressure.
  • Immediately before reaching the maximum level limit in the receptacle 1.6 of the permanent magnet acts on the electric circuit 7.1 7.1, whereby the motor 1.7 is turned off.
  • the float 7 also closes the suction opening 1.10.
  • the suction pipe 3.1 can remain hanging in the water unchanged.
  • a check valve 3.2 is arranged in the suction element 3.
  • the check valve 3.2 may e.g. be designed in one piece as a sniffer valve made of elastomer / rubber. When switching off the motor 1.7 is prevented by the suction in the element, for. B. a hose of 5 m length, does not flow back into the pond and there stirs up dirt.
  • the check valve 3.2 is preferably formed from four rubber flaps.

Claims (5)

  1. Aspirateur de boues comprenant un élément d'aspiration (3), qui est relié à un réservoir de réception (1.6), dans lequel un fluide liquide peut être collecté jusqu'à une position de remplissage maximale, un élément de vidange (5) étant raccordé au réservoir de réception (1.6), dans lequel un clapet de dépression (5.2) est agencé, qui s'ouvre lorsque la position de remplissage maximale est atteinte, et comprenant un moteur (1.7) pour la production d'un courant d'aspiration, qui produit une contre-pression, qui est supérieure à la dépression qui règne dans le réservoir de réception (1.6), le moteur (1.7) présentant un interrupteur électrique (1.9), qui met hors circuit le moteur (1.7) en fonction de l'atteinte de la position de remplissage maximale, ce qui provoque l'ouverture du clapet de dépression,
    caractérisé en ce que,
    il est adjoint au circuit électrique (1.9) un flotteur (7), qui est guidé dans un boîtier (1) et qui entraîne la fermeture du circuit électrique (1.9) lorsque la position de remplissage maximale est atteinte, et qui débranche le moteur (1.7) tout en fermant une ouverture d'aspiration (1.10), le circuit électrique (1.9) étant relié à un temporisateur, qui provoque la remise en circuit du moteur (1.7) par le circuit électrique (1.9) après un laps de temps nécessaire pour un vidage complet du réservoir de réception (1.6).
