Definitions

  • the invention is for a clamping device for holding an ex­plosion panel on the safety opening of a holder in which there is a dust, gas or vapour, which explosion panel will in the event of an excess of pressure, for example as a result of an explosion in the holder, be thrown open or blown off so that the holder sustains little or no dama­ge.
  • a flexible panel which can be held on the holder by a variety of means. In the event of an explosion in the holder the panel bends and the perimeter of the panel comes free of said means so that the panel is blown off.
  • the means of retaining the panel consists of a number of leaf springs located around the perimeter of the panel, one end of which is mounted on the panel and the other end of which fits into a slot of a perpendicular support or frame mounted on the holder. In the event of an explosion the panel is pressed upwards and each flexible spring slides out of the slot of its support, so that the panel is blown off and the safety opening of the holder is cleared.
  • a major disadvantage of this is that the springs do not permit a good seal between the panel and the perimeter of the opening to be achieved. In order to remedy this to some extent, it is necessary to give the panel a rela­tively complicated shape. Yet another disadvantage is that the springs do not retain their springiness and are sensitive to temperature changes, so that it is diffi­cult to determine previously the opening pressure and/or opening time.
  • the invention provides for a clamping device in which a frame is fasten­ed around the safety opening and in which the explosion panel is rigid and provided with a retaining edge on which the free end of the clip strips fastened at an an­gle to the frame engages, pressing the explosion panel onto the frame.
  • the clamp­ing device and explosion panel according to the invention has the advantage that it is simple in construction and relatively cheap to make and that the explosion panel is easy to install.
  • the clamping device can be very precisely set to react to a predeter­mined very low or very high opening pressure at which it comes loose and is blown away. The opening pressure of the explosion panel can therefore be accurately deter­mined and is measurable.
  • Yet another advantage is that after a mild explosion the panel can be used again and only the clip strips have to be replaced. Finally the opening pressure at which the explosion panel must open can be accurately determined in advance by changing the number and characteristics of the clip strips with which the explosion panel is fixed in position.
  • the holder 1 which contains any dust, gas or vapour whatsoever and in which a safety opening 2 has been provided.
  • a per­pendicular frame 3 is fastened by means of, for example, of bolts 4.
  • On the outside of the frame there are several supporting pieces or U shaped brackets 5 at predetermined distances in which a clip strip 6 which slopes downwards and made of any material whatsoever, is fastened by means of a screw 7.
  • each clip strip 6 engages in a retaining edge 8 preferably turned to the horizontal of the outwardly sloping sides 9 of a rigid and not hea­vily constructed explosion panel 10 of any material what­soever, such as for example stainless steel, so that the explosion panel is firmly and sufficiently pressed onto the elastic seal 11 which is mounted on the perpendicu­lar frame 3.
  • the force necessary to make the explosion panel come free of the safety opening 2 is determined by the buckling resistance of the clip strips 6. This buckling resistance of each strip can be accurately cal­culated on the basis of the dimensions of the clip strip and the strength coefficient of the material from which the clip strips 6 are made.
  • the special shape of the clip strips 6 means that they exercise a constant pres­sure on the explosion panel 10, so that when combined with the rigid construction of the explosion panel they ensure perfect closing of the safety opening 2 of holder 1.
  • the clamping device and the explosion panel according to the invention when the normal operating pressure exerted on the panel is relatively close to the opening pressure of the explosion panel, when premature or unanticipated opening of the panel is undesirable or when the panel is subject to strict operating conditions.
  • the ex­plosion panel 10 When an explosion takes place in the holder 1, the ex­plosion panel 10 is lifted and the stiff retaining edge 8 of the explosion panel pushes the free end of the clip strips 6 upwards (fig. 5), so that the explosion panel slides freely over the clip strips and is blown free of the safety opening 2 of the holder 1. After a mild ex­plosion the rigid panel is usually not damaged and it is enough to replace the clip strips 6 in order to restore the device to good working order.
