Definitions

  • the invention relates to a suction device which has a suction device with a suction head which has at least one suction unit for forming a suction flow, and with a dirt receptacle which is releasably held on a filter device and is in flow connection with the at least one suction unit via the filter device and the has a suction inlet and accommodates a liquid bath, wherein a suction nozzle adjoining the suction inlet in the flow direction of the suction flow is immersed in the liquid bath, and a float valve is arranged in the flow path between the suction nozzle and the filter device for shutting off and releasing the flow path depending on the fill level of the liquid bath.
  • Such suction devices are often also referred to as industrial vacuum cleaners and are used, for example, to extract dust, especially explosive dust. They have a suction head which includes at least one suction unit to form a suction flow. They also have a dirt holding container which is in fluid communication with the at least one suction unit via a filter device.
  • the dirt collection container has a suction inlet to which a suction line, for example a suction hose, can be connected. Under the effect of the suction flow, suctioned material can be sucked into the dirt collection container via the suction inlet.
  • the dirt holding container holds a liquid bath, that is, it can be filled with liquid, for example water or oil, and a suction nozzle adjoining the suction inlet in the flow direction of the suction flow is immersed in the liquid bath.
  • liquid for example water or oil
  • suction nozzle adjoining the suction inlet in the flow direction of the suction flow is immersed in the liquid bath.
  • a float valve is arranged in the flow path of the suction flow between the suction port and the filter device. With the help of the float valve, the flow path of the suction flow can be blocked or released depending on the fill level of the liquid bath. If the liquid bath is insufficiently filled or there is no liquid bath, the float valve shuts off the flow path, i.e. the suction flow is interrupted so that no suction material, especially explosive dust, can be sucked into the dirt collection container. When the liquid bath is sufficiently full, the float valve opens the flow path so that suction material, especially explosive dust, can be sucked into the dirt collection container. The suction flow then extends from the liquid bath via the filter device to the at least one suction unit, and the filtered suction air can be released from the at least one suction unit into the environment without endangering health.
  • the dirt collection container is detachably held on the filter device and can be separated from the filter device for emptying and filling with liquid.
