Definitions

  • the invention relates to an explosion closure plate, in particular explosion hatch, of the type mentioned in the preamble of claims 1 and 2.
  • Explosion sealing plates of this type can be used in particular in systems in which dust explosions are to be expected. Their valve-like effect is intended to prevent plant parts from being torn or damaged at undesired locations by a certain excess pressure.
  • the explosion flaps represent the "weakest" parts of the system or the container or the wall, so that the overpressure can compensate there.
  • such explosion closure plates can also be used in devices in which undesired negative pressure is to be expected, provided that a further opening is provided with the plate reversed, however.
  • the pressure at which the "relief" is to take place is quite difficult to set, especially when the plate size reaches an area of the order of 1 square meter.
  • the invention is therefore based on the object of improving the explosion closure plate of the type mentioned in such a way that, despite the simple design, a better adjustability to the response or the specific positive or negative pressure is possible.
  • the clamping profile is bridged by at least one lever arm, one side of which is articulated either on the wall - or the plate.
  • the other side of the lever arm is supported directly or indirectly on the plate - or the wall or the clamping profile, when a locking member, which is designed in particular as a shear pin, prevents pivoting of the lever arm about the articulation point in the closed position.
  • a locking member which is designed in particular as a shear pin
  • the holding pressure which holds the plate in the opening of the wall, is transmitted in the invention by the seal consisting in particular of rubber or rubber-elastic plastic and designed as a clamping profile.
  • the lever arm serves for additional support of the plate in one direction. As a result, the plate can be blasted out in both directions, but is nevertheless easily adjustable with regard to the limit pressure.
  • the plate is given the possibility of evading in the direction of the lever arm and guessing out of the clamping profile or pushing the clamping profile out of its mounting in the wall in order to enable pressure equalization.
  • the "explosive force" which must be achieved in order to deactivate the locking element can be adjusted accordingly by a suitable choice of the design and the material of the locking element, which is designed in particular as a shear pin, and by a suitable selection of the distance thereof from the articulation point. In order to obtain adjustability in this regard, it is advisable to make the distance from the locking member to the articulation point changeable.
  • a loading opening with approximately several square meters of opening area is closed by means of a plate 4, which forms the explosion closure plate according to the invention / innovation and also as a »hatch «Can be called.
  • the outer edge of the plate 4 is inserted into a recess of the clamping profile 1, the opposite recess - as can be seen in particular from FIG. 2 - is pushed onto the edge 9 of the wall 3 delimiting the opening.
  • the clamping profile 1 forms a seal in this closed position, so that rain or sea water cannot penetrate into the loading space covered by the plate 4.
  • the clamping profile 1 holds the plate 4 in the desired position.
  • the plate 4 In addition to this mounting of the plate 4, which is a known arrangement, it is also supported by means of the lever arm 2, which is articulated at its end shown on the left in FIG. whose web part is welded to the wall 3. At the opposite end, the lever arm 2 is provided with an adjusting element 8, which is designed as a screw and whose free end can be turned to the outside of the plate 4. The distance G from the upper edge of the lever arm 2 to the outside of the plate 4 can now by screwing the screw, d. H. of the setting element 8.
  • the lever arm 2 is additionally connected to the bearing block 6 at a distance A from the articulation point 7 by means of a shear pin serving as a locking element 5.
  • This distance A is, for example, 70 mm, with a distance B of about 30 cm from the point of attack of the adjusting element 8 on the plate 4 to the articulation point 7.
  • a screw with the thread M 12 is used as the setting member 8, for example, while the shear pin consists of aluminum with a diameter of 6 mm.
  • the bearing block 6 is a U-iron with a thickness of 4 mm and the dimensions 40 x 50 x 40 mm.
  • the lever arm 2 is also a U-iron, but with the dimensions 40 x 60 x 40 mm, so that there is no play on both sides between the inside of the legs of the lever arm 2 and the outside of the legs of the bearing block 6.
  • the leg height D of the bearing block 6 is therefore 40 mm.
  • the distance G from the articulation point 7 to the edge 9 of the wall 3 delimiting the opening in this exemplary embodiment is approximately 12 cm.
  • the width of the lever arm 2 is 60 mm and the width F of the pedestal 6 is 50 mm.
  • the plate 4 is articulated on the side shown on the left with conventional joints on the wall 3, while it is only on the right side by means of the lever arm 2 and the same design as in FIG. 1 is torn open from the locked position to the open position when a certain limit pressure is exceeded.
  • the joints 10 ensure that the plate 4 is not thrown away, but remains on the wall 3.
  • the bearing block 6 is fastened to the underside of the plate 4, so that the holding force can be adjusted via the lever arm 2 and the adjusting element 8 in that the screw forming the holding element 8 is pressed onto the inside of the wall 3 and screwed in further the pressure is increased. If the set limit pressure is exceeded, the locking member 5 shears through, so that the lever arm 2 can be pivoted counterclockwise and the plate 4 can be torn out of the rubber-elastic clamping profile 1.
  • the locking member 5 is arranged on the side opposite the adjusting member 8 from the articulation point 7 of the lever arm 2.
  • the torque is determined by the distance A between the articulation point 7 and the locking member 5.
  • the ratio of this distance A to the distance B also determines the force relationships between the force used to shear the locking member 5 and the pressure force acting on the plate 4 .
  • the distance between the point of attack of the setting element 8 on the Plate 4 and the locking member 5 and the articulation point 7 are made adjustable.
