Definitions

  • a pressure-resistant tank of the type specified in the preamble of claim 1 is known from DE-C-2 253 235.
  • this container designed as a tank container, four partially circular cylindrical jacket shells forming the tank jacket are inserted between two end frames of the container. Between these end frames also run outside the tank jacket, four U or L-section beams, each of which projects with a flange into the bead between two abutting jacket shells.
  • the ends of tie rods which run through the interior of the tank and penetrate the tank jacket in the bead area, are welded to these flanges of opposing profile beams.
  • the tie rods in the interior of the tank are designed to be tubular.
  • the known tank requires correspondingly heavy front frames to fix the massive profile beams and therefore has a high weight. Furthermore, a relatively large number of tie rods is provided, which not only further increase the weight of the tank, but also mean a high manufacturing effort and considerably hinder the cleaning of the tank interior.
  • a tank container is also known, the upper and lower curved jacket shells of which are attached to the upper and lower tubular longitudinal spars extending in the longitudinal direction of the container and which are connected to one another via a pulling wall dividing the entire container into two chambers.
  • This container is also expensive to manufacture and has a high tare weight due to the continuous draw wall. Because of the partition, cleaning the interior of the container is also complex here.
  • the invention has for its object a tank admit, which has the lowest possible weight with high compressive strength, is easy to clean and easy to manufacture.
  • the solution to this problem according to the invention is characterized in claim 1.
  • the tubular longitudinal spars provided thereafter, each inserted between two adjacent jacket shells, need not be too heavy, since they are reinforced in the fastening areas of the tie rods by inserted sections of another tube. Because of these reinforcements in the tubular longitudinal spars, a few tie rods are sufficient. For a given compressive strength, the forces occurring in the few tie rods can be easily introduced into the longitudinal spars without causing undue stress peaks or bending. A small number of tie rods are favorable from the standpoint of manufacturing, tank empty weight and cleaning the inside of the tank.
  • the embodiments of the invention according to claims 3 and 4 are useful in terms of the achievable strength of the tie rods themselves and their connection to the longitudinal spars.
  • the measure according to claim 5 serves to prevent a relative movement between the tubular longitudinal spar and the pipe section inserted into it, in order to bring the reinforcing effect of the pipe sections to full advantage.
  • the development of the invention according to claim 6 is favorable with regard to the cleaning of the tank interior and also allows the tank to be closed at each of these points by an attachment on the tank bottom; alternatively, the ends of the tubular longitudinal spars can be closed by additional sheet metal pieces which run as pulling and doubling elements over part of the tank bottom.
  • the tank is made of stainless steel or another high-quality material
  • the reinforcement pipe sections lying inside the longitudinal spars are made of less noble, but high-strength material.
  • the jacket shells can be in one piece in the longitudinal direction and do not, as previously, need to be composed of several individual transverse wefts. This results in an overall shorter weld seam length and easier assembly.
  • the further training according to claim 9 has the advantage that no additional weight-increasing measures on the tank are required for any cooling or heating apart from the external feed lines and connections.
  • the tank is composed of four parallel, partially circular cylindrical jacket shells 10 and two tank bottoms 11 on the front side.
  • the tank has a cloverleaf-like shape in cross section, the axes of the four jacket shells 10 defining the corners of a rectangle.
  • the tank is connected to two container end frames 14 via lower saddle pieces 12 and upper support elements 13.
  • a tubular longitudinal spar 15 runs in the longitudinal direction of the tank, which, as can be seen particularly clearly from FIG. 1 above, is chamfered at its ends at approximately 45 ° or more flat such that its smallest length extends to the inside of the tank is facing and its greatest length ends at the point where the tank bottom 11 in question begins.
  • four gusset-shaped sheet metal pieces 16 are canted at the aforementioned angle of approximately 45 ° or flatter, which engage in the respective bead area between two jacket shells 10 and at the same time close the part of the oblique end face of the tubular longitudinal strut 15 located outside the jacket shells 10.
  • the tank jacket is also surrounded by two reinforcement rings 17 which follow the approximately cloverleaf-like contour of the tank shown in FIG.
  • Tubular tie rods 18, 19 penetrating the tank interior are also provided perpendicular to the tank axis.
  • a vertical tie rod 18 and a horizontal tie rod 19 are provided directly next to one another so that they touch one another in the area of the intersection and can be connected to one another for further stiffening.
  • With a tank length of 20 feet (6058 mm) a total of four tie rods 18, 19 are provided.
  • Each tie rod 18, 19 completely penetrates the respective longitudinal spar 15 at its ends and protrudes a short distance the outside of it.
  • the longitudinal spar 15 is reinforced by an inserted pipe section 20.
  • the pipe sections 20 are cut obliquely at both ends such that the greatest length of each pipe section 20 faces the interior of the tank. This results in a gradual transfer of tension from the reinforced region of the longitudinal strut 15 to the non-reinforced region, the inner longest tongue-like end regions of the tube sections 20 having a certain elasticity.
  • the end of the tie rod 18 is welded to both the longitudinal spar 15 and the pipe section 20 both at the penetration point located inside the tank and at the outside of the tank. Since the reinforcing effect of the tube section 20 is only fully achieved if relative movements between this and the tubular longitudinal spar 15 are excluded, these two components are directly connected to one another via welds which are made along the edges of recesses 21 provided in the tubular spar 15.
  • the two jacket shells 10 are each welded to the tubular beam 15.
  • the pipe sections 20 that do not come into contact with the cargo are made of high-strength structural or fine-grained steel.
  • a further saving in high-quality tank material can be achieved in that the continuous longitudinal spar 15 is also made of less high-quality tank material and, according to FIG. 4, is surrounded in its area lying inside the tank by a partially cylindrical sleeve 22 made of tank material, which has the longitudinal spar on its longitudinal edges 15 is welded and to which the jacket shells 10 attach.
  • the tubular longitudinal spars 15 and tie rods 18, 19 can be used to conduct a cooling or heating medium, which is supplied via (not shown) external leads and connections.
  • a cooling or heating medium which is supplied via (not shown) external leads and connections.
