  • Generic suction devices are known for example from DE 30 07 345 Al, DE 103 08 349 B4 or DE 92 10 965 Ul. If such suction devices are used to aspirate health-endangering substances or even carcinogens, there is a problem in that care must be taken when emptying the collecting container and / or during the associated changing of the filter body and a fine filter following the filter body, to prevent the previously sucked material from escaping from the sump or the filter body and the operator may possibly come into contact with the hazardous substances.
  • the solutions known from the prior art offer no guarantee for this, which is why sometimes even protective suits and protective masks must be worn when emptying the collecting container or when changing the filter body of these suction devices.
  • the closing device has a holding rod for holding the closing element, by means of which the closing element is movable between its opening releasing the inlet opening and its closing position.
  • the closing element can be adjusted very easily and in particular without coming into contact with the fine filter, between the two mentioned positions.
  • the holding rod has at its end facing away from the closing element a thread on which a nut is mounted.
  • the closing device accessible by removing a lid of the housing and the closing element of the same is movable, so a very easy accessibility to the closing device according to the invention is given.
  • the closing element is formed as can be brought by the induced draft in its open position flap. In this way, there is an automatic opening and closing of the leading from the sump or the filter body in the fine filter opening, which significantly reduces the operating effort.
  • the flap by means of a locking device in its closed position is stable.
  • a further advantageous development of the invention may consist in that the fine filter is held in the housing by means of a holding device.
  • the holding device for the fine filter provides the same a secure holder within the housing.
  • a structurally very simple and the fine filter securely holding embodiment of the holding device can be given if the holding device has two spaced-apart retaining flanges, which are interconnected by means of rods, where -A -
  • rods are releasably secured by means of respective fastening elements on at least one of the retaining flanges.
  • the filter body dressed holding flange is designed as a lid of the collecting container and having an opening for the induced draft.
  • a securing device can be provided in a very advantageous development of the invention, which only enables loosening of the holding device for the fine filter when the closing element is in its closing the inlet opening of the fine filter position.

  • FIG. 5 shows a perspective view of the collecting container with the filter body arranged therein.
  • FIG. 6 is a plan view of the collection container of FIG. 5th
  • Fig. 1 shows a device 1 for the extraction of not shown pulver or dust-like material, in particular health-endangering substances.
  • the suction device 1 is particularly suitable for use in the pharmaceutical industry, since there the contact of a person operating the suction device 1 should be prevented under all circumstances with these health-endangering or even classified as carcinogenic substances.
  • the suction device 1 is also suitable for the extraction of other materials.
  • the suction device 1 has a housing 2, in which a collecting container 3 indicated in FIG. 1 by means of a dashed line is arranged. To the removable from the housing 2 in a manner not shown collecting container 3 performs a suction line 4, which is brought in a conventional manner by the operator to the respective extraction point. Furthermore, the suction device 1, a suction unit 5, which may be formed, for example, as an electric motor or a electric motor lektromotor and in a conventional manner a Induced draft in the suction line 4 produces. The suction unit 5 shown only very schematically is connected via a connecting line 6 to the housing 2.
  • the negative pressure generated by the suction unit 5 is planted in the housing 2 and from there into the collecting container 3 and finally into the suction line 4, so that the powdery or dusty material can be sucked with this negative pressure.
  • the suction unit 5 and the housing 2 are arranged in the present case on a plurality of wheels 7 having suspension.
  • the suction device 1 could also be stationary, ie without a chassis, be formed.
  • Fig. 1 Inside the housing 2 are located in the direction of in Fig. 1 denoted by "x" suction between the suction line 4 and the suction unit 5 arranged filter body 8 for filtering coarse dusts and in the direction of the suction between the filter body 8 and the suction unit. 5 arranged fine filter 9 for filtering fine dusts that may leave the filter body 8.
  • a first embodiment of the suction device 1 is shown in more detail in a sectional view.
  • the filter body 8 is formed in the shape of a bag, which is arranged in the collecting container 3.
  • the suction line 4 opens via an opening 10 in the housing in the filter body 8, which also has an opening 11 in this area.
  • the suction line 4 opens into the filter body 8 such that the induced draft x enters the filter body 8 via the openings 10 and 11 and flows through the filter body 8 from inside to outside through a wall.
  • the fine filter 9 is held by means of a holding device 12 in the housing 2 of the suction device 1. From the section of FIG. 2 further shows that the holding device
  • the filter body 8 dressed holding flange 13 is formed as a lid of the collecting container 3 and has an opening 15 for the induced draft.
  • the retaining flange 13 which has been prepared for the filter body 8, is sealed by means of a peripheral sealing element 16.
  • two extending in the vertical direction of the housing 2 rods 17 are further arranged, which extend to the upper, the filter body 8 facing away from holding flange 14 and there extend through respective recesses 18 in the upper retaining flange 14.
  • the rods 17 have at this end in each case not shown thread, which are each in engagement with a nut formed as a fastening element 19 in engagement. In this way, the two rods 17 can be releasably attached to the upper retaining flange 14 of the retainer 12, thereby ultimately holding the fine filter 9 and against a circumferential seal member 20 on the lower retaining flange
