Definitions

  • the invention relates to a container with a removal funnel, in particular a silo, which has a substantially cylindrical container main part, a container flange welded to the lower end of the same and a removal funnel welded near the lower end, which starts from the welding point downwards, i.e. . H. opposite to the main part in particular tapered conically.
  • Such containers are set up for various storage, storage and other purposes and are used, for example, to house building materials, raw materials or raw materials for further chemical processing into plastics, for example, but also for agricultural purposes.
  • the height or axial length can be many meters, for example 20 meters, for large containers.
  • a removal funnel is arranged on the inside in the lower part, which tapers downwards towards a removal opening in such a way that the last remainder of the container contents also slide down to the removal opening by gravity.
  • the great weight such large containers must have great strength.
  • the container or parts of it should not bulge.
  • the removal funnel is adapted with its front end of the largest outside diameter to the inside diameter of the main part in the vicinity of the lower front end of the same and welded to it there.
  • This welding point is usually arranged at an axial distance from the lower edge or container flange.
  • the welding point should be a continuous annular welding point and, in view of the often large diameter, on the order of z. B. a few meters, a uniform contact of the outer edge of the discharge funnel on the inner wall of the main container part is not always guaranteed. Uneven welds are often the result, which results in unreliable welding.
  • the invention relates to an already known container of the type mentioned in the preamble of claim 1 (DE-A-2615562).
  • the object of the invention is to improve such a container in such a way that not only the welding in the correct position is facilitated but also the danger a crack formation or even a tearing off of the removal funnel during operation is avoided or at least largely prevented.
  • the container flange or the ring flange has a support projection on the inside for supporting the front end of the removal funnel with the largest funnel diameter.
  • the removal funnel is therefore not welded directly to the wall of the main container part on the inside thereof. Rather, the welding takes place between the wide front end of the discharge funnel and a component that is substantially thicker or more stable and more resistant to resistance than the main part wall, namely the container flange or the additional ring flange, which offers a number of important advantages.
  • Direct welding to the additional ring flange is particularly advantageous since the welding between the removal funnel and the ring flange can be made more easily accessible and can therefore be carried out more easily.
  • the removal funnel can be separated from the container main part in a very simple manner and can be re-attached to it by merely loosening the ring flange and bringing it back together. This allows the transportation of bulk can be made easier because the removal of the discharge funnel with the ring flange reduces the overall axial length.
  • a further advantage is, however, that the main part and the removal container can still be transported together without a greater axial length than that of the main part itself.
  • the ring flange is only screwed to the container flange in an inverted position, that is to say opposite to the actual installation position, so that the removal funnel is in this shortened transport position within the main part.
  • the container flange or ring flange has a support projection on the inside for supporting the front end of the removal funnel.
  • the removal funnel is then simply plugged with its front end of the largest diameter onto this support projection serving as a holding member.
  • the welding of these two components then takes place without special holding clamps etc. having to be provided.
  • the strength of the welded joint under load is also significantly improved.
  • the ring flange or container flange can be produced for this purpose very simply and inexpensively and nevertheless extremely stably if it is produced from an extruded profile, in particular extruded from aluminum or an aluminum alloy.
  • an annular segment is formed from an elongated rod of such an extruded profile by rolling and its approaching front ends are expediently welded to one another so that the required ring tension can be absorbed by this ring flange.
  • the support projection can also be formed straight away.
  • Such a support ring expediently consists of a cross-sectionally U-shaped profile, which in turn is expediently rolled into a ring and has suitable through holes in order to be connected on the one hand to the container flange and possibly the ring flange and on the other hand - if necessary - on a foundation or support to be anchored.
  • Such steel support rings are ideal for transmitting the forces that occur, which means that the silo weight can also be weighed using modern three-point support methods.
  • such a support ring also has a further task: if conical shapes are used for the main part, rather than strictly cylindrical ones, a larger number of main parts can be inserted into one another and transported together. After plug-in stacking of such main parts, at the end of the stack, namely at the open end of the largest diameter, the stacks of the reverse, i.e. H. into the corresponding removal funnel projecting into the main parts, the support ring of each container simultaneously serving as a spacer for the ring flanges of the removal funnels also assembled in such a plug-and-stack arrangement.
  • the invention therefore represents a particularly happy solution to various subtasks: it not only simplifies production.
  • a very stable container is also created for large volumes, which is easy to assemble and disassemble, and which takes up very little transport space even when transported in large numbers, which is particularly important with silos or tanks of large lengths , if they are to be transported on semitrailers, freight wagons or ships, for example. So it is possible to be able to transport not only one, but a larger number of e.g. 5 to 10 silos at once on a semi-trailer, provided the semi-trailer can withstand the total weight.
  • the main part 1 is designed here as a silo Large-capacity container composed of several parts, namely the main part 1, the ring flange 6 with the removal funnel 3 and the support ring 7, which was anchored on support beams 10 in a manner not shown.
  • 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, on which ropes, chains or the like can engage in order to be able to lift the container or only the main part 1.
  • 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 it 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 up 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 13 runs vertically.
  • the aluminum wall of the main part 1 is double-welded to the container flange 4 at the lower end, specifically at a weld 23 on the inside of both parts and at a fillet weld 24 on the outside of the two parts.
  • the welding point 21 connects between the upper end 20 (end with the largest diameter) of the removal funnel 3 and the inside of the ring flange 6, so that there are as far as possible no niches and filling material without obstruction along the inside the main part 1 and the removal funnel 3 can slide down.
  • the removal funnel 3 is supported at the upper end on the frustoconical support surface 25 of the support projection 19 of the ring flange 6, as a result of which not only a great deal of force can be absorbed, but also better pre-adjustment and mounting for welding.
  • the support ring 7 is located below the aluminum ring flange 6. This is made of steel and forms a U-profile in cross section over the two legs 14 and the web 15. Through the container flange 4, the ring flange 6 and one leg 14 the support ring 7 go through through holes 16, 17 and 18, which serve to receive bolts, so that these three parts can be screwed together in a simple manner. Such a through hole 16 is also located in the lower leg 14 of the support ring 7, for example for anchoring on the support beams 10 or foundations.
  • the removal funnel 3 has an inclination to the container axis 13
  • the wall of the main part 1 is not cylindrical, but is also slightly inclined upwards and inwards from the welding points 23, 24 by the angle ⁇ .
  • the assembly formed from the removal funnel 3 and the ring flange 6 can be connected to the container flange 4 in a position opposite to that shown in FIG. 2, so that the removal funnel 3 projects inwards.
  • the support ring 7 is screwed to the ring flange 6 below (the screw connection is not shown separately) and to the underside of the support ring 7, also not shown, a ring flange, also not shown, of another removal funnel 3a is screwed on, so that the support ring 7 here as a spacer between adjacent nested funnels 3, 3a is used.
  • the removal funnel 3 is welded directly to the container flange 4 in an analogous manner to that which was done with the additional ring flange according to FIG. 2.
  • the ring flange 6 is saved, but the container flange 4 is modified so that it is equipped with the support projection 19. This design is particularly recommended for smaller containers with a cylindrical main part 1.
  • a support ring 7 can also be used here, the container flange 4 being placed on the support ring.
