Definitions

  • the invention relates to a stackable large-capacity container, in particular a silo, with a main part that tapers conically upwards to a head part, which in particular has a filling opening, at an angle of inclination to the container axis, and is welded at the lower end to a container flange, which is particularly suitable for fastening further container parts , for example a withdrawal funnel.
  • Such a large-capacity container is already known (DE-PS 2 159 602).
  • the stackability of such large containers offers the following advantage in particular: considerable transport costs between the production site and the place of use are saved.
  • a whole series of several container main parts provided with the container flange and head part which have a diameter of, for example, several meters and a length many times the diameter, can be plugged into one another, which means that they take up much less space when transported on large tractors, railway wagons and ships than if a corresponding transport space is made available for each of these parts, as is the case with other large-capacity silos known, for example, from US Pat. Nos. 3,023,019 and 4,109,819.
  • Even if the transport of such known, essentially cylindrical silos is facilitated by placing them on trolleys, each large-capacity container requires the transport space it occupies.
  • the invention is therefore based on the object to improve stackable large-capacity containers of the type mentioned in such a way that they can be stacked despite the manufacturer's attachment of detachable closure plates and can be transported in a nested arrangement from the manufacturer to the customer or the place of use or installation location of the container.
  • the invention consists in that between the head part and the main part a neck part is inserted, which tapers from a connection point with the main part to the connection point with the head part at an acute angle of inclination with respect to the conical main part.
  • the closure plate which can at least partially be blasted out at a certain internal container pressure or vacuum, is inserted in a closable manner in an opening arranged in the region of the neck part.
  • a closure plate which can be inserted directly into the opening of the neck part by means of at least one bend-elastic clamping profile and whose clamping profile can be bridged by at least one lever arm, one side of which is articulated on the neck part - or the plate is and the other side is supported on the plate - or the neck part - when a shear pin or the like in the event of overstressable organ that prevents the lever arm from pivoting about its pivot bearing in the closed position when the specific overpressure or underpressure occurs by shearing a pivoting of the lever arm around the pivot bearing, however, allowed.
  • a clamping profile which is weakened, for example by cutouts, in the region of the space between the opening edge of the neck part and the outer edge of the closure plate. It is advisable to attach the weakening on the side accessible from the outside, after which the closure plate should be able to be blasted out.
  • the most expedient is the use of a single annular clamping profile which delimits the entire opening edge of the neck part, so that the closure plate is also completely surrounded by the clamping profile ring in the closed position.
  • the large-capacity container designed here as a silo is composed of several parts, namely the main part 1 made of aluminum or steel, the ring flange 6 with the removal funnel 13 and the support ring 7, which is mounted on support beams 10 in a manner not shown at the place of use, e.g. a large construction site or at a chemical plant.
  • the main part 1 is provided at the top with the filling opening 11 and at two, three or even more points with fastening elements 12, 12a, on which ropes S, chains 100 or the like can engage, to lift the container or only the main part 1 or parts with one another to be able to secure.
  • the container flange 4 At the lower end of the main part 1 there is the container flange 4 and in any case during transport at a certain distance from this an additional retaining ring 2 which serves as a spacer with the support struts 5 which run along the outside of the wall of the main part 1 to the retaining ring 2.
  • the container flange 4, the ring flange 6 and the support ring 7 are held together by means of screw bolts 8, so that the container forms a structural unit in the position shown in FIG. 1.
  • the removal opening 9 is located at the lower end of the removal funnel 3. In this functional or use position, the container axis 14 runs vertically.
  • the wall of the main part 1 is inclined at an acute angle ⁇ between 0.5 ° and 15 ° with respect to the container axis 14 - in this case also with respect to the vertical - so that the container tapers upwards.
  • a neck part 20 is welded in between the main part 1 and the strongly inclined head part 21, the angle of inclination of the container axis 14 being substantially greater than the main part angle of inclination ⁇ .
  • the neck part 20 is provided with an opening which receives the detachable closure plate 22.
  • the individual main parts 1 of the containers are supported in the transport position on their open front end, which has the largest cross section, on a chassis 16, the edges 19 of which can roll on rails 17 in the container axis direction 14.
  • the innermost or rearmost main part 1 d is also supported on the inside by means of a horizontally extending holding device 18, so that its front tapered end cannot move downwards when stacked one inside the other.
  • the container axes 14 run in the horizontal direction. In this direction the main parts 1 are also assembled. For this purpose, they have not only the fastening element 12a at the upper tapered end, the head part 21 of the container, but also at the lower end, namely the container flange 4. There, the load cables S 3 and S 4 act to lift and move the individual main parts 1.
  • each main part 1 is provided with a container flange 4 and a retaining ring 2, which are located at a certain distance from one another, the retaining ring 2 serving as a mounting ring surface for the container flange 4 of the adjacent main part 1 .
  • the main parts 1 are provided with fastening elements 12a serving as lifting eyes, which are welded on the inside of the neck part 20 according to FIG. 4c and protrude through the head part 21.
  • the upper part of the closure plate 22 and the neck part 20 and the adjoining lower region of the head part 21 are shown schematically in cross section, while in FIG. 4b the transition region of the lower part of the neck part 20 and sealed by the closure plate 22 is shown the main part 1 is shown.
  • the head part 21 is inclined at an angle of inclination 8 of approx. 15 ° within the preferred range between 0 ° and 30 ° with respect to the normal plane 30, which intersects the container axis 14, not shown here, and also the vertical indicated in FIG the wall of the adjacent main part 1x inclines upward in the direction of the peeler axis 14 at the angle of inclination indicated in FIG. 1.
  • the outer edge 21 x of the head part 21 protrudes radially somewhat beyond the connection point 24 designed as a fillet weld at the upper end of the neck part 20.
  • the fastening member 12 which is designed in the form of a web or angle, is welded to the upper side of the head part 21, so that a safety chain 100 with the handle 25 connects to the closure plate 22.
  • the neck part 20 is provided with a clamping profile 21 around the edge of the opening into which the closure plate 22 is inserted Rubber exists and is shown even more clearly in FIGS. 5-7. While handles 25 are welded to the outside of the closure plate, there are welded bearing blocks 26 on the outside of the neck part 20 near the opening edge, from which lever arms 23 extend beyond the area of the clamping profile 31 to the area of the closure plate 22 and there by means of the adjusting members 28 formed as screws are pressed. The pressure transmission takes place in a manner which is explained in more detail for example with reference to FIG. 6.
  • the neck portion 20 is inclined significantly more with respect to the container axis 14 than the wall of the main part 1, there is a sufficient distance between the head part 21 of a main part and the head part due to the distance between the retaining ring 2 and the container flange 4 according to FIG. 1, for example of the adjacent main part 1x x available, which is only indicated schematically in Fig. 4b.
  • This distance designated by M in FIG. 3 in conjunction with the greater conicity or inclination of the neck part 20 compared to the main part 1, ensures that there is sufficient space in the intermediate space 33 in FIG.
  • the other parts located radially outside the neck part 20, such as the adjusting member 28 and the handle 25, are then also at a distance that is sometimes even greater than the distance a l from the radially outside adjacent main part 1x, with which the neck part 20 and therefore also the closure plate 22 is inclined at an angle of inclination a of approximately 4 ° within the preferred range between 2 ° and 20 °.
  • the connection point 27 between the neck part 20 and the main part 1 is also a weld seam.
  • an opening with approximately several square meters of opening area is closed by means of the explosion closure plate 22.
  • the outer edge of the plate 22 is inserted into a recess of the clamping profile 31, the opposite recess - as can be seen in particular from FIG. 6 - is plugged onto the edge 29 of the neck part 20 which delimits the opening.
  • the clamping profile 31 forms a seal in this closed position, so that rain or sea water cannot penetrate into the container interior covered by the plate 22.
  • the clamping profile 31 holds the plate 22 in the desired closed position.
  • the lever arm 23 which is articulated at its end shown in FIG. 6 on the left in FIG. 6 by means of a screw bolt at the articulation point or the pivot bearing 37 on a bearing block 26 with a U-shaped cross section is, the web part is welded to the neck part 20.
  • the lever arm 23 is provided with an adjusting member 28 which is designed as a screw and whose free end can be turned to the outside of the plate 22. The distance C from the upper edge of the lever arm 23 to the outside of the plate 22 can now be changed by screwing the screw, ie the adjusting member 28.
  • the lever arm 23 is additionally connected to the bearing block 26 at a distance A from the pivot bearing 37 by means of a shear pin 15 serving as a locking member.
  • the ratio of this distance A to distance B also determines the force relationships between the force used to shear off the shear pin 15 and the pressure force which acts on the plate 22.
  • This distance A is, for example, 70 mm, with a distance B of about 30 cm from the point of attack of the setting member 28 on the plate 22 to the rocking bearing 37.
  • a screw with the thread M 12 serves as the setting member 28, while the shear pin 15 is made of aluminum with a diameter of 6 mm.
  • the bearing block 26 is a U-iron with a thickness of 4 mm and the dimensions 40x50x40 mm.
  • the lever arm 23 is also a U-iron, so that there is no play on both sides between the inside of the legs of the lever arm 23 and the outside of the legs of the bearing block 26.
  • the distance C from the articulation point 7 to the edge 29 of the neck part 20 delimiting the opening is approximately 12 cm in this exemplary embodiment.
  • the width of the lever arm 23 is 60 mm and the width of the bearing block 26 is 50 mm.
  • the cylindrical shear pin 15 protrudes on both sides above the lever arm 23 or bearing block 26 and is prevented from slipping out there by means of clip rings 15a.
  • the clamping profile 31 is provided on the side facing away from the excess pressure with a recess 31 x, so that the opening of the closure plate 22 is facilitated.
  • the distance between the point of attack of the setting point 28 on the plate 22 and the shear pin 15 or the pivot bearing 37 can also be made adjustable.
