Definitions

  • the invention relates to a steel drum, consisting of an outer container with an outer drum shell with a circular cross-section and folded top and bottom and an inner container with a precise fit therein with an inner container shell with folded top and bottom, and wherein the top of the outer container with the top of the Inner container are connected to each other in the region of a barrel bung.
  • a steel drum with these features is known (DE-A-2 134 034), the top and bottom bottoms being connected to the drum casing by a multiple fold.
  • Such barrels are primarily manufactured as standardized 55-US gallon barrels (EP-A-0 162 873), these barrels being used in particular for the transport of environmentally hazardous goods.
  • these barrels can be designed to be ISO container-compatible, since such ISO containers can be optimally loaded with these barrels.
  • the special and increasingly strict legislative requirements mean that such dangerous goods drums must be made of steel or stainless steel, whereby the dangerous goods such as oils, paints, varnishes, emulsions, thinners and the like. must not be stored in such barrels.
  • the drums In order to enable such storage, it has become common to arrange the drums in conventional collecting trays, e.g. drum stack pallets, but this is associated with a considerable cost factor and, moreover, the drum, as a classic, manually controllable individual container, has its mobility or mobility is taken.
  • the invention is based on the object of proposing a steel drum and a method for its production which are suitable both for transport and for storage and not only for the intermediate storage of environmentally hazardous goods with high stability.
  • This object is achieved according to the invention in that, in the case of the containers designed as independent containers with a drum jacket or container jacket and top and bottom, the inner container with its fold connections is supported in the area of the largest diameter of the fold and its positive beads on the inside of the drum jacket .
  • top of the inner further container in the area of the bung holes be curved outwards and that the top of the outer barrel shell be shaped to match the shape of the first top and that a connecting flange is used to connect the top floors to the bung holes.
  • the upper floor of the outer barrel casing is cut out enlarged in the region of the barrel bung holes and welded to the other upper floor.
  • top bottoms at the barrel bung holes be drawn in against one another in the edge region and have stair-like shoulders towards the barrel bung holes.
  • test opening is provided in the top floor of the outer barrel casing.
  • the outer barrel is a standardized (DIN 6643) 55-US-gallon barrel, in which a standardized (DIN 6643) inner barrel is used with smaller dimensions.
  • An advantageous method for producing such a steel barrel, with an outer barrel jacket to which an underbody is crimped is that in the outer barrel jacket another steel container, consisting of another barrel jacket with a crimped top and bottom, is used so that the first top floor of the outer barrel jacket is connected to the top floor of the further steel container and that the first top floor is crimped onto the upper edge of the barrel jacket.
  • Another advantageous process step is that the two top floors are connected by flanges in the region of the bung holes.
  • the invention has the essential advantage that a double-walled bung-type drum is available which meets the highest safety requirements with regard to the transport and storage of environmentally hazardous goods. Due to the accuracy of fit of the inner barrel to the outer barrel, a perfect fit is guaranteed at all times, so that a such a barrel meets the required tests by drop tests and internal pressure stresses. Conventional machines and systems can be used to manufacture the barrel.
  • the keg can be created from two DIN-compatible kegs by producing the outer keg as a 55-US gallon keg according to DIN 6643 and the inner keg according to the same standard, but with slightly reduced external dimensions.
  • the bung holes are located in such an area that a connection to the automatic filling and plug screwing systems is ensured. Due to the still specially designed design of the two top floors in the area of the barrel bungs, the actual closure is relieved of load. Furthermore, the shape of the top floors in the area of the barrel bores results in a residual emptying of the barrel.
  • used steel drums can also be reconditioned to the double-walled drums according to the invention.
  • the barrel shown in Figures 1 and 2 consists of an outer steel barrel with a cylindrical outer barrel jacket 1 with bottom 3 and top 2.
  • the connection of top 2 and bottom 3 with the barrel 1 is made by folded joints 7 and 8.
  • a correspondingly constructed inner steel barrel with a cylindrical container jacket 4 and top shelf 5 and bottom shelf 6 is inserted with an exact fit, the top shelf 5 and the bottom shelf 6 being connected to the barrel jacket 4 at fold connections 9 and 10, respectively.
  • the container jacket 4 is provided with positive beads 14. The diameter of these beads 14 or over the largest diameter of the fold connections 9 or 10 is such that the inner barrel is supported on the inside 16 of the barrel jacket 4.
  • connection of these two steel barrels placed one inside the other takes place in the region of the barrel bung holes 11 and 12, a first embodiment of such a connection possibility being shown in FIG. 3.
  • the top floor 2 of the outer steel barrel is drawn in stepwise in the area of such a barrel bung 11 or 12, in that in a first step 21 at the transition of the lid edge into the fold 7, the top floor rests against the fold 9 of the inner steel barrel.
  • the top floor 2 is adjusted to the top floor 5 of the inner steel barrel, which in turn is above an outwardly increasing inclined step 23 is approximated to the top floor 2.
  • connection to barrel bung holes 11 and 12 takes place with the aid of a connecting flange 17 which has a circumferential edge 25 abutting the underside of the inner top floor 5, which has a cylindrical section through the opening of the Barrel bung hole 11 or 12 is passed through and has a flange 22 on the outside, which surrounds the upstanding edges of the two top floors 2, 5.
  • a test opening 15 is provided in the top floor 2 of the outer steel barrel.
  • the upper top floor 2 is provided with a cutout 19 which is enlarged compared to the barrel bunghole 11, 12 and the corresponding circular edge of the upper top floor 2 is welded to the lower top floor 5 at this cutout 19, wherein a weld seam 20 is present.
  • the most frequently used container is the standardized 55-US-gallon barrel, which can be made according to DIN 6643 ISO container-compatible or not ISO container-compatible.
  • the outer barrel must be designed with these dimensions.
  • the inner barrel to be inserted into this outer barrel is also to be manufactured in accordance with the standards, namely in accordance with the same DIN standard 6643 with reduced dimensions.
  • the inner barrel consisting of the container jacket 4 and the top shelf 5 and the bottom shelf 6 is completely manufactured.
  • the underbody 3 is first folded onto the outer barrel jacket 1.
  • the top shelf 2 of the outer barrel is placed on the top shelf 5 of the inner barrel, the connecting flanges 17 being inserted from the inside through the barrel bung and the circumferential one Edge 25 abuts the inside of the top 5.
  • the flange is then folded over at its upper edge in the region of a flange 22, as a result of which the two trays 2, 5 are connected to one another.
  • the inner drum is inserted into the outer drum and the top panel 2 is folded together with the outer drum jacket 1 in the area of the fold connection 7.
  • the procedure is similar, the upper floor 2 being welded to the floor 5 in the region of the barrel bung holes 11, 12 before the floor 2 is crimped onto the outer barrel jacket 1.
