Definitions

  • the invention relates to a respiratory protection filter, according to the preamble of claim 1.
  • the respiratory protection filters have to clean the air we breathe while retaining the respiratory toxins.
  • they have a suspended matter and a gas filter part, which are flowed through in succession.
  • the respiratory protection filters are used in conjunction with breathing connections as filter or escape filter devices. However, it is only really carried on the man and does not interfere with use, if it is constructed in a space-saving manner and as little as possible obstructing it.
  • a known filter respirator of the type mentioned in the first part of claim 1, in particular as a filter self-rescuer for mining, contains a filter part in which the filter media are accommodated side by side in round, flat filter parts provided with openings on the end faces.
  • the filter parts form a common container in which they are connected to one another by a likewise flat air duct.
  • the outflow opening of the filter part last flowed through continues in a further air duct to the connection piece, such as a mouthpiece, for the respiratory organs.
  • the standby air inlet opening in front of the first filter part is closed by a stopper.
  • the container can consist of a weldable, gas and water vapor impermeable plastic.
  • an air filter which contains a cylindrical main filter part, around which a secondary filter part in the form of an annular section is arranged concentrically.
  • the main filter part and the secondary filter part are separated from one another by an air space through which the air to be filtered is fed to both filter parts.
  • the object of the invention is a respiratory protection filter containing a suspended matter and a gas filter, which is as small as possible to carry with the man, and which can be produced easily and also in large numbers.
  • This object was achieved according to claim 1 via a housing design with an arrangement of the suspended matter and gas filters, with which both a flat and a small overall housing was created, which can be manufactured cheaply in the spraying process. Thanks to the covers over the respective housing parts, the two filters can be safely assembled from individual parts directly in their housing parts or used as complete individual filters prefabricated on the outside. The lids then close e.g. by gluing the housing.
  • the desired arrangement of the supply air and exhaust air nozzles either vertically on or under the housing or from the side with the axis lying makes an inexpensive way of carrying them possible.
  • the housing 1 contains, in separate filter parts, a suspended matter filter 2 and a gas filter 3, through which the air to be inhaled flows in succession in the direction of the arrows 4, 5, 6, 7, 8.
  • the suspended matter filter 2 is arranged in a housing section 9 in the form of an annular segment, concentrically with the gas filter 3 located in a round housing part 10.
  • a gusset chamber 11 formed thereby carries an inlet air connector 12 and a gusset chamber 13 an exhaust air connector 14.
  • the gusset chamber 11 is connected to the suspended matter filter 2 via a passage 15 and this is then connected to the gas filter 3 via a passage 16. Behind this, the cleaned air to be inhaled then flows through a passage 17 through the gusset space 13 and exhaust port 14 to the breath connection.
  • the housing 1 For mounting the suspended matter 2 and gas filter 3, the housing 1 has a cover 18 for the housing part 9 and a cover 19 for the housing part 10.
  • the connecting pieces as shown in dashed lines at 20, can also be arranged sideways on the gusset spaces 11, 13.
