Definitions

  • the invention relates to a cuboid collecting container according to the preamble of patent claim 1.
  • waste materials KTC and intermediate bulk carrier IBC
  • the waste materials to be disposed of could be solid, pasty, liquid, pure or contaminated, sticky, toxic, caustic, chemically aggressive, flammable or non-flammable, water and environmentally hazardous, harmful to health, odor-intensive, hygroscopic, also in combination.
  • Certain building and testing regulations apply to these collecting tanks. You currently have to withstand up to 2.0 bar overpressure. Often, the waste material sticks to the walls and preferably in the corner areas of the collecting container, so that it cannot be discharged properly through the emptying opening, especially if the hardened contents adhere to deformations or weld seams or beads.
  • safe emptying and thorough cleaning must be possible in order to prevent dangerous residual components, e.g. Avoid PCB, chloride or the like.
  • a frameless cubic tank container with a convex side surface and reinforced corner formation is a common design for a collection container. With this The above-mentioned disadvantages occur in modern collecting containers.
  • a stackable collecting container of the type mentioned in which the side surfaces are curved outward in the form of a cylindrical shell.
  • the corner areas are sharp, e.g. with a radius of only 25mm, rounded.
  • the weld seams of the container section composed of plates are provided in the corner areas.
  • the aforementioned disadvantages also occur with this known collecting container.
  • the collecting container bulges at a higher internal pressure, which e.g. with full filling with a liquid can lead to the collection container bulging out during filling and absorbing a few vol.% more liquid than would correspond to its relaxed volume. When emptying, the container relaxes after opening the lid, which pushes out some of the liquid and pollutes the environment or endangers the operating personnel.
  • the side walls and corner areas are rounded.
  • the container is used to transport pressurized goods, especially powder or granules.
  • the curvatures of the walls are chosen so that the greatest possible capacity within the dimensions of an outer, rectangular frame is achieved.
  • the aspect of an interior surface that is as smooth as possible is irrelevant here.
  • a pressure vessel known from DE-U 85 12 278 with a rectangular frame skeleton rounded transitions from the flat sides to the flat floor can be seen.
  • the invention has for its object to provide a collection container of the type mentioned, which can be emptied and cleaned properly even with difficult waste materials and is characterized in use by increased strength against overpressure or underpressure.
  • the curved side surfaces in cooperation with the rounded corner areas allow considerably higher pressure loads than flat surfaces or flat surfaces with bead reinforcement. Waste residues can hardly adhere to the evenly running surfaces, or it is easier to remove adhered residues than from right-angled corner areas or corners with only slight rounding. Furthermore, the container shot can be produced with a single weld seam in the best case, whereby the number of weak points is reduced and bumps for adhering residues of the waste materials are avoided. The small number of welds made possible by the training also saves manufacturing costs.
  • a further, particularly advantageous embodiment is set out in claim 3.
  • This conical shape of the container shot is in terms of emptying and Cleaning particularly cheap.
  • the resulting contours of the blank for the container shot with the curved side surfaces and the rounded corner areas can be produced in a simple manner, for example on a program-controlled plasma cutting system, with such high precision that no problems arise during further processing.
  • the embodiment of claim 4 is also advantageous, because only a single weld seam is required in the container section, so that the container section can be welded in an economical and prefabricated part on an automatic and relatively simple welding system, whereby - possibly using a bath safety device - a welding factor of 1.0 is reached. Due to the constant weld seam course due to the uniform curvature of the side surfaces and the corner areas, an automatic welding of the peripheral seams in the area of the base group and the upper border is also possible.
  • the embodiment according to claim 5 is also expedient because two longitudinal seams are practical for conventional manufacturing processes.
  • the idea of claim 6 is also important because this simplifies the manufacture of the container shot.
  • the corner areas are expediently bent simultaneously in a bending device, namely up to approximately 85 °, it being expedient to produce the container section from two parts.
  • the embodiment of claim 8 is also important because in the manufacture of the bent molded part the side walls do not need to be bent if they are arched into the desired shape by means of an assembly aid during welding to the base group and the upper casing. Geometric changes and tolerances resulting during the assembly process and welding process can be easily compensated for in the corner areas during welding.
  • the feature of claim 9 is also important because this curvature also achieves the compressive strength in the floor area or in the top floor area, which allows the configuration of the side wall and corner area, and because the transitions that arise in this way have as few surveys as possible for the application of waste material. Leftovers arise.
  • the manufacture is further facilitated by the measures according to claim 10, because the flanges allow a clean connection to the container closure and allow flawless welds. Here too, corner or gusset areas are avoided, which could favor the adherence of waste residues.
  • a further, expedient embodiment, in which the cover sits on the edge of the container protection with a sealing ring and can be fixed by means of closure elements on the outside, is evident from claim 11.
  • closure elements With this arrangement of the closure elements, a very high compressive strength is achieved, because the line of action between the closure elements with the outermost line of the sealing force is approximately coincides, so that the bearing moments from the internal pressure and spring force of the seal remain manageable without any special effort.
  • This area of the collecting container which is particularly critical with regard to the sealing, is simply adapted in this way to the increased pressure resistance of the collecting container.
  • a frameless cubic tank container or waste material collecting container 1 according to FIGS. 1a-1d has a frame-shaped base group 2 on which a container section B in the form of a suitably prefabricated bent molded part 3 is fastened.
  • the container section B consists of side walls 4a-4d and corner areas 5 lying between two side walls.
  • FIG. 1d shows that the side walls 4a-4d are each accustomed to the outside with a radius R in the form of a cylindrical shell, the radius R being between 1.5 and 1.5 cm. and 10 times the largest side length S of the collecting container 1.
  • the corner regions 5 between the side walls are each rounded with a radius r in the shape of a cylindrical shell, which is between 0.07 and 0.3 times the side length S.
  • the rounded corner areas 5 are nestled between the curved side walls, so that there are no transitions here.
  • the side length is approximately 1100 mm, R approximately 2000 mm and r approximately 200 mm.
  • a frame-shaped border 6 with integrated stacking corners 7 is fastened on the upper edge of the container section B.
  • matching corners 8 are provided in the stacking corners, which contain non-highlighted starting points for the lifting fork of a forklift.
  • the collecting container 1 is closed on the upper side by a lid 9, which is either smaller than the upper side or extends over the entire upper side, as in FIG. 1a indicated.
  • the lid 9 is fixed with closure elements 10 in the closed position, which are distributed along the circumference of the lid 9 and anchored in the enclosure 6.
  • a floor 11 is contained in the floor assembly 2, which is welded to the container section B and, like the lid 9, is convex to the outside.
  • the opposite side walls 4b and 4d are lifting eyes 12 for a hoist and fittings 13 attached.
  • the container section B is expediently formed from a band-like blank as a bent molded part 3 and closed with a single weld seam 14 in the side wall 4a. It would also be conceivable, as indicated in Fig. 1d, to produce the container section B from two bent molded parts and to connect it accordingly with two weld seams 14, 14 'in the opposite side walls 4a and 4c.
  • the corner regions 5 are pre-bent with their final radius r up to approximately 85 ° in the bent molded part.
  • the side walls 4d and 4b and the side wall halves of the side walls 4a and 4c remain stretched. Your curvature with the radius R can be produced in a simple manner by assembly aids when connecting the container section B to the base group 2 and the upper casing 6.
  • FIGS. 2a and 2b it can be seen how the container section B is connected to the base group 2.
  • the bottom 11, which is cambered outwards, is formed via a plate-edge transition 15 with a straight extension 11 ', which is turned downwards around a support profile 17 on the outside.
  • Another support profile 16 is included below the plate edge transition 15 in the floor assembly 2, on which also Stand angle 8 from individual profile parts 18 are attached.
  • the bottom 11 Up to the plate edge transition 15 (Fig. 2b) the bottom 11 is curved with a radius R 'to the outside, while it is curved in the plate edge transition 15 with a radius r' to the opposite side.
  • the container section 19 is attached to the extension 11 'with a circumferential weld 19.
  • This type of plate transition is very pressure-resistant and favorable with regard to the formation of the weld seam 19.
  • the radius R 'can correspond to the radius R of the curvature of the side surfaces.
  • the radius r ' is chosen so that the plate transition 15 remains without notch stresses or beige stresses.
  • FIG. 3a and 3b the connection of the container shot B with the border 6 can be seen.
  • An upper floor 20 (provided that the lid 9 is smaller than the cross-section defined by the container section B) is curved according to FIG. 3b with a radius R 'and passed over the plate edge transition 23 with an extension 20' into the border 6, where the extension 20 'turned up and inside and welded to the stacking corners 7.
  • the radius R 'of the top panel 20 may correspond approximately to the radius R of the side surfaces.
  • the radius r 'in the plate edge transition 22 is chosen so that no notch effect occurs.
  • the container section B is connected to the top floor 20 by a circumferential weld seam 24.
  • FIG. 4 A part of the lid 9 can be seen from FIG. 4, which is placed either on an opening edge 21 of the upper floor 20 (FIG. 3a) or on the edge of the container weft or a reinforcing strip 30 welded there (FIG. 6).
  • the lid 9 is curved outwards with a radius R ⁇ and via a plate edge transition 25 welded with a radius r 'to a cover edge profile 26, which consists of a circumferential angle profile 28 and an externally attached band profile 29.
  • a seal 27 is provided, which stands on the edge of the profile 30.
  • the radius R ⁇ can approximately correspond to the radius R of the side surfaces.
  • Fig. 5 shows how the closure elements 10 and 10a and 10b are distributed along the circumference of the lid 9 in order to ensure an optimal sealing effect with increased internal pressure.
  • the closure elements 10a and 10b which are adjacent to each other in each corner region 5, are arranged such that a straight connecting line between them affects the sealing line between the seal 27 and the profile 30.
  • This type of fastening is provided both for a cover 9, which is placed on the edge 21 of the top panel 20 according to FIG. 3a or on the profile 30 according to FIG. 6.
  • FIG. 6 Another embodiment can be seen from FIG. 6, in which the side walls (only the side wall 4a is shown) diverge upward in the container section B, in each case at an angle 33 of between 1 ° and 5 °.
  • the conical container section B is connected in the region of the base group 2 to the base 11, which in this embodiment has a flange 34 which corresponds to the course of the lower edge of the container section B.
  • stiffening elements 35 are welded on the outside in the gusset between the base group 2 or a cover profile 36 of the base group 2 and the flare.
  • the cover profile 36 is also welded to the underside of the bottom 11.
  • the upper border 6 contains the profile 30, which is welded to the container section B via a weld seam 32 and creates a peripheral seat edge for the lid 9 according to FIG. 4.
  • the radius R is between 1500mm and approx. 10000mm.
  • the corner areas are designed with radii between 80mm and approx. 300mm.
  • the container section B can be welded in a prefabrication on an automatic and relatively simple welding system, a weld factor of 1.0 possibly being achieved using a bath safety device. Due to the constant course of the weld along the edges of the container weft, automatic welding of the peripheral seams is also possible with relatively simple welding robots.
  • the radii of the corner areas 5 are simultaneously bent in a bending device, advantageously only until the side walls enclose an angle of approximately 85 °. The radii of the curvature of the side walls do not necessarily have to be pre-rolled or bent.
  • the locking elements 10 can be screw connections, clamps, toggle locks or the like. Due to the special arrangement in the corner areas, the force line of action between the adjacent closure elements 10a and 10b coincides approximately with the outermost line of the sealing force, so that the contact moments from the internal pressure and the The spring force of the seal can be controlled without any special effort.
  • the resulting contours of the blank for the container closure in the conical embodiment according to FIG. 6 can be produced with high precision without any problems on a program-controlled plasma cutting system.
