Definitions

  • the present invention relates to a sludge sucker according to the preamble of claim 1.
  • Such a sludge sucker has the disadvantage that a motor is connected to a ball valve.
  • the ball valve is located close to the level limit of the receptacle. With increasing filling of the receptacle and reaching the filling level limit, the ball valve is brought into a closed position, which causes the motor to run audibly faster. Depending on this acoustic perception, the user must manually turn off the engine so that an automatic drainage can take place via the drain element.
  • Such a procedure can lead to the acoustic changes of the engine not being perceived or not being noticed in time, so that the receptacle overflows or the engine is damaged.
  • the object of the present invention is therefore to create a sludge sucker with which fully automatic emptying can be carried out during a sludge suction process.
  • the sludge extractor according to the invention has the advantage that the motor no longer has to be switched off manually as a function of an acoustic change. Rather, the engine now switches off automatically so that emptying can begin automatically.
  • the device can also be converted into a conventional wet vacuum in a simple manner.
  • oasl015b 1 is a schematic view of a sludge sucker of the present invention
  • 2 shows a schematic view of an electrical circuit of the sludge extractor according to the invention.
  • a sludge extractor 1 comprises a housing 1.1, on which a connection 1.2 for a suction element 3 and a connection 1.3 for a drainage element 5 is formed.
  • the housing 1.1 is also formed in its upper region remote from the floor as a cover 1.4 which is detachably fastened to the lower housing 1.1.
  • the housing 1.1 is provided with a foot element 1.5.
  • the interior of the housing 1.1 is designed in its central region as a receiving container 1.6 for sludge and water or materials of a similar consistency.
  • the connection 1.2 is in the upper part of the receptacle 1.6 and the connection 1.3 is in the lower part of the receptacle 1.6, preferably diametrically opposite the connection 1.2.
  • a motor 1.7 preferably an electric motor, is arranged, which has a well-known suction device 1.8, such as. B. drives an air-drawing wing element. During the drive, air is sucked out of the receptacle 1.6 and released to the outside via openings in the upper housing area. 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 maximum fill level limit of the receptacle 1.6 provided in a suction opening 1.10 of the suction device 1.8.
  • a guide housing 5 for a float 7 is formed in the receptacle 1.6.
  • 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 are arranged concentrically therewith. In other embodiments, a concentric arrangement need not necessarily be provided.
  • the float 7 has a permanent magnet 7.1 on an upper side remote from the floor.
  • the float 7 With increasing filling of the receptacle 1.6, the float 7 is moved upward in the guide housing 5 along the longitudinal axis. Shortly before the maximum fill level limit is reached, the permanent magnet 7.1 acts on the electrical circuit 1.9 opposite it in the suction opening 1.10 and closes it. As a result, the engine 1.7 is switched off. When the maximum fill level is reached, the float 7 also closes the feeding opening 1.10.
  • the electrical circuit 1.9 is preferably a reed circuit. In other embodiments, other switches and switching systems can also be used.
  • the electrical circuit 1.9 is connected to a timer (not shown), which can be set so that the motor 1.7 is automatically switched on again after the receptacle 1.6 has been completely emptied via the drain element 5. The time required for complete emptying depends on the volume to be emptied and can be predetermined.
  • the drain element 5 is releasably attached to the connection 1.3 in a generally known manner and comprises a vacuum valve 5.2 at its free end 5.1.
  • the drain element 5 is also a hose or a tube.
  • the suction element 3 hangs in the water or another liquid fluid with a suction nozzle 3.1.
  • a suction process begins. Sludge, for example, is sucked from the pond bottom of a pond through the suction element 3 and the suction opening 1.10 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 due to the prevailing vacuum.
  • the permanent magnet 7.1 acts on the electrical circuit 1.9, as a result of which the motor 1.7 is switched off.
  • the float 7 also closes the feeding opening 1.10.
  • the proboscis 3.1 can remain stuck in the water.
  • a check valve 3.2 is arranged in the suction element 3 on the proboscis 3.1.
  • the check valve 3.2 can, for example, be constructed in one piece as a snifting valve made of elastomer / rubber. With Aboaslöl5b Circuit of the motor 1.7 is prevented by the fact that in the suction element, for. B. a hose of 5 m in length, does not flow back into the pond and whirls up dirt there.
  • the check valve 3.2 is preferably formed from four rubber tabs.
  • the vacuum in the receptacle 1.6 is eliminated, so that the vacuum valve 5.2 opens due to the internal pressure now generated by the sludge and the sludge runs out through the drain element 5 until the receptacle 1.6 is empty again. Then the motor 1.7 can be switched on again, so that the process is repeated.
