Definitions

  • the invention relates to a device for ventilation of protective suits, in which a blower driven by an electric motor and the batteries required to drive the blower are arranged in a portable small container, the small container having a filter connection for the suction side of the blower and at least two connections is provided for connecting lines to the protective suit or to a breathing mask.
  • Protective suits for use in an area contaminated with toxins must be airtight or gas-tight. Therefore, the user of such a suit can only stay in the protective suit for a very limited time.
  • devices with devices of the type mentioned at the outset have become known which are light in weight, are extremely easy to handle and deliver a sufficient amount of air with sufficient pressure.
  • the blower is designed as a radial blower. It has been shown that relatively small radial fans are sufficient for adequate ventilation of protective suits and can be easily carried by the user of the protective suit.
  • Document US-A-4 649 715 describes an apron to which a fan is attached, which is supplied with power from the outside via a supply line.
  • the blower itself has a pressure connection to which a line is connected, in which a control device is arranged.
  • a control device By means of this control device, a rotary slide valve or a throttle, the air flow can be directed under the apron and / or back again to the outside or under the apron and / or in the area of a face shield.
  • Such a device is unusable for use in protective suits and breathing masks.
  • Document GB-A-2 121 879 describes a fan for air conditioning systems which is provided with a spiral housing and has two outlets, the air flow through these outlets being able to be controlled by means of an adjustable wall in such a way that the distribution of the air flow over the two outlets can be varied is.
  • the primary objective of the present invention is to further improve the known devices (see, for example, FR-A-2 345 171, which is considered to be the closest prior art) in that, in addition to the ventilation of protective suits, they also serve to supply Breathing masks are usable.
  • the arrangement of further connections is not sufficient. It has been found that the amounts of air required, on the one hand for the supply of protective suits and on the other hand for the supply of breathing masks, are different, it being possible to assume a ratio of about 1: 4 to 1: 6.
  • the object is achieved in that at least one of the connections is provided with a control device which can be actuated from the outside of the small container for changing the amount of air flowing through independently of the other connection, and in that the control device is designed in the form of a rotary slide valve as a flexible sheet which can be pushed on the inside of the connection via its opening by means of a handle which can be actuated from the outside.
  • connection If at least two connections are arranged in the direction of rotation of the flexible sheet, a particularly wide control range can be achieved. Both connections can then be regulated by one sheet.
  • FIG. 1 is an inventive device in the left half shown in view and right half in section.
  • Fig. 2 shows on an enlarged scale the section through the middle housing part of the device with the rotary valve according to the invention.
  • a portable small container 1 has a lower part 2 with two inserted filter connections 3, a central part 4 and a cover 5.
  • the middle part 4 is screwed to the lower part 2 with the interposition of a seal 6 and the cover 5, also with the interposition of a seal 7, is held on the middle part 4 by means of quick-release fasteners 8.
  • a carrying strap 19 is also attached to the middle part 4.
  • a radial fan 9 with an attached electric motor 10 is fastened by screws, not shown, via a washer 11 to the lower part 2, so that the suction side 12 of the fan 9 points against the filter connections 3.
  • 4 connections 14 and 15 are arranged in the middle part, onto which connecting lines to the protective suit or respiratory mask can be pushed.
  • a rotary slide consisting of a flexible sheet 20 which can be rotated via a handle 22 arranged on the outside of the central part 4 and connected to the sheet 20 via a shaft 21.
  • the sheet 20 can be partially or wholly brought through one of the openings 14 or 15 or both openings 14, 15, so that a very large control range is created and the device can be adapted to the respective needs to a very large extent.
  • connection 23 is also shown in FIG. 1, the flow cross section of which is reduced by the arrangement of an orifice 24. Through this diaphragm a throttle point is created so that less air will flow through the connection 23 than through one of the connections 14 or 15 when the rotary valve is open or not present.
  • a breathing mask which in any case requires less air than a protective suit, could be connected to the connection 23. It is accordingly an inventive one Device also possible to provide only connection 14 (without rotary valve) and connection 23, for example. Even then, different quantities are delivered at the two connections.
  • the container 1, but in particular the lower part 2 and middle part 4 can be provided with a heat-insulating layer.
  • a heat-insulating layer Such an externally attached layer 26 is indicated by dashed lines. However, the layer could also be arranged on the inside.
  • blower 9 In the context of the invention, it would also be possible to provide the blower 9 with two spiral housings each enclosing different peripheral parts. Depending on the degree of wrap of the volute casing, a different amount of air will therefore escape from the corresponding socket of the casing.
