Definitions

  • the invention relates to a container with a lining, in particular a lining consisting of a GRP laminate, and with an intermediate layer arranged between the lining and the inner wall of the container, the lining being attached to the container at least at the upper edge of the container.
  • Container liners of this type are generally made from a chemically resistant material, for example from glass fiber reinforced plastic laminate (GRP laminate), in order to make a container made of concrete or steel suitable for holding chemically aggressive substances.
  • GRP laminate glass fiber reinforced plastic laminate
  • a primer is usually applied to the bare metal surface prepared by sandblasting.
  • the concrete surface must be dry, free of oil and dust and have sufficient tensile strength.
  • a filler mixture made of plastic is applied, on which the GRP laminate is then adhered.
  • the top layer of the GRP laminate can be designed as a seal with a particularly dense and chemically resistant surface.
  • the filler layer In the case of rough subsoil, as is also the case, for example, with new concrete containers, the filler layer must be at least so thick that it compensates for all outstanding unevenness in the subsoil. Because of the firm connection of the lining with the filler intermediate layer and with the inner wall of the container, no set cracks or other subsequent movements in the wall of the container may be permitted, as these would be transferred to the lining and could also lead to cracking there.
  • the object of the invention is therefore to carry out a container with a lining of the type mentioned in such a way that the necessary preparatory work is substantially reduced, so that even old containers, the inner wall of which is not suitable for connection to a lining, can be retrofitted without excessive work can be provided with a lining without cracks and loose parts of the inner wall of the container impairing the lining.
  • the intermediate layer consists of soft elastic material. This largely prevents the transfer of forces between the inner wall of the container and the lining. Therefore, tensile stresses exerted by the lining on the inner wall of the container cannot lead to detachments on the inner wall of the container, nor can cracks and other damage have a damaging effect on the lining, even if the cracks should still make subsequent movements. Unevenness in the inner wall of the container does not penetrate the soft, elastic intermediate layer and therefore cannot damage the lining. Loose or otherwise unsuitable parts of the inner wall of the container, for example remnants of old linings, do not have to be removed, which considerably reduces the requirements for the preparation of the inner wall of the container.
  • the intermediate layer preferably consists of fine-pore, closed-pore foam material, whereby Polyethylene foam has proven particularly effective, which preferably consists of loosely inserted sheets, such as sheets or sheets.
  • the lining Since there is no load-bearing connection between the lining and the inner wall of the container in the area of the introduced foam material, the lining is worn by its own tensile strength like a shirt suspended in the container, the upper edge of the lining being fastened to the container.
  • the lining is firmly connected to the inner wall of the saline in spaced-apart fastening surface regions and that the soft-elastic intermediate layer is only outside these fastening surface regions is arranged between the lining and the inner wall of the container.
  • Fastening intermediate layers are preferably fastened to the inner wall of the container in the fastening surface regions and the lining is firmly attached thereto.
  • the intermediate fastening layers can be, for example, vertical struts and / or — in the case of essentially rotationally symmetrical containers — rings or ring segments which can be dowelled on the inner wall of the container or fastened in some other way.
  • the fastening intermediate layers can consist of steel or GRP.
  • the lining made of GRP laminate is attached to its inside by adhesion.
  • a standing cylindrical container 1 is made of concrete.
  • the interior of the container is provided with a lining 2 made of a GRP laminate, which is, for example, a roving laminate, a mat laminate or a fiber spray laminate, the glass fiber inserts of which give the lining sufficient tensile strength so that it is at least to a certain extent self-supporting.
  • the lining 2 is firmly connected to the container surface after appropriate preparation.
  • polyethylene foam sheets 4 are inserted, which are connected point by point to the container inner wall 3 to hold the inserted foam sheets 4 during assembly.
  • the container At vertical intervals to each other and to the upper Be the edge of the container are made of steel rings 5, which can also consist of individual ring segments 5 ', fastened to the wall of the container 1 by means of dowels 6 and dowel screws 7.
  • the lining 2 is attached to the surface of the rings 5 or ring segments 5 'by adhesion. In the areas in between, the lining 2 lies only loosely on the foam sheets 4 and supports itself. The distance between the rings 5 or ring segments 5 'is selected such that bulging of the lining 2 is prevented.
  • vertical struts 5 a can be provided at a distance from one another, which in the illustrated embodiment also consist of steel and are connected to the inner wall 3 of the container and the lining 2 in the manner described.
  • a corner fillet 8 can be provided by a spatula layer 9.
  • the container inner wall 3 was not machined to accommodate the lining 2; it can carry bumps, old leaking brickwork, more or less loose surface areas or remnants of an old surface coating.
  • the container 1 itself may have cracks or joints.
  • the foam sheets 4 form a buffer layer, which prevents the liner 2 from being adversely affected and, in particular, its surface quality.
  • FIG. 2 A modified way of fastening the liner 2 to the upper edge of the container 1 is shown in FIG. 2.
  • a standing ring 5 attached to the upper edge of the container on the inner wall 3 of the container, which ring is connected to the upper edge of the lining 2 by adhesion.
  • This type of attachment is particularly useful when the container has a cover (not shown) that cannot be removed, so that the top of the container edge is not accessible for the attachment of the liner 2.
  • the struts 5a, rings 5, ring segments 5 'or similar fastening intermediate layers can, for example, also consist of GRP and be glued to the container 1 or also be dowelled.
  • FIG. 3 A further modified embodiment is shown in FIG. 3.
  • the GRP lining 2 is glued to vertically arranged or annular circumferential strips 5 ′′ made of synthetic resin concrete, which are introduced into mortised grooves 6 of the wall of the container 1.
  • the foam sheets 4 are located between strips 5 ′′, on the surface of which the lining 2 lies loosely.
  • FIG. 4 Another modified embodiment is shown in FIG. 4.
  • the GRP lining 2 is on the inside brought reinforced GRP ribs 2a, which, for example, also serve as vortex breakers in agitator tanks.
  • the ribs 2a increase the strength of the liner 2 so that additional fastening intermediate layers such as the rings 5 or the like are not provided or are only provided at relatively large intervals.
  • the container 1 can also consist, for example, of steel and have a rubber reinforcement or some other coating or remnants thereof on its inner wall 3, which does not have to be removed at least in the area of the foam sheets 4 in order to cover the lining 2 to attach.
  • foam material described for the plates 4 instead of the foam material described for the plates 4, another soft-elastic material can also be used, for example sheets made of thermoplastic.
