Definitions

  • the present invention relates to a baffle for a container, in particular transport container, which in each case has a recess in the sole and in the apex region of the transport container, on the separated by the baffle container areas are in communicating connection.
  • Transport containers for liquids such as tank containers or tanker semitrailers have a significant influence on the driving behavior of road vehicles.
  • liquid cargo to the pure mass effects weight forces, increasing the center of gravity, inertia
  • add significant dynamic influences since liquid cargoes in partially filled transport containers during transport back and forth and swings on the container and thus exert on the entire vehicle.
  • transport regulations stipulate that road transport of containers with a filling level between 20 and 80% is only permitted if the total volume of the container falls below a certain size (for example 7.5 m 3) ) or the total volume obstructing by the surge wall elements divided so that there is no container area that exceeds the above-mentioned limit of 7.5 m 3 .
  • surge-preventing elements serve removable or permanently installed elements inside the container, usually so-called baffles, which enforce the most elongated transport containers transversely to the longitudinal direction.
  • Baffles have recesses in the sole region and in the apex region, so that the regions separated from the baffles are in communicating connection with one another and a liquid and / or pressure equalization can take place between the container regions during filling and emptying.
  • the recess in the sole region also serves to allow the container to be completely emptied or filled at a single removal / filling point, for example via a bottom fitting or a riser.
  • the recess in the apex area is mainly used to allow pressure equalization to take place between all tank areas separated by baffles during filling, emptying or during transport.
  • the individual separated from the surge walls container areas must be accessible for inspection and inspection purposes.
  • a closable inspection opening - a so-called manhole - is then provided in the container outer wall for each container area. If the transport containers are designed as pressure vessels, then such manhole arrangements are likewise pressure-resistant and thus comparatively difficult and expensive.
  • Fig. 4 shows a known baffle design, in which a passable access opening is provided in the center of the baffle. This means that every single container department is accessible via a single container manhole. The passage through such an opening, however, may be cumbersome because a round sharp-edged opening must be climbed. In particular, the recovery of a person is very difficult through such an opening. In addition, such a relatively large walk-through reduces the anti-surge effect, especially in the filling area (about 50% filling level), in which the swirling effects due to the large free load surface area are maximal.
  • the object of the present invention is to provide an improved baffle.
  • a baffle with the features of claim 1, a baffle arrangement according to claim 9, a container according to claim 10 and a tank container according to claim 12. It is provided that the recess in the sole region is formed so that it is also suitable as a maintenance pass , Passable formed by a person, and the recess in the upper area narrower is as at the bottom.
  • a shaped recess in the sole region has several advantages over the known embodiment:
  • connection or connection area with the surrounding container wall can be shortened, which also has manufacturing advantages (the number of fastening screws or the weld length can be reduced).
  • This design is also advantageous for the passage, the anti-surge effect and the complete emptying.
  • the baffle is formed as a curved disc element. This gives it an increased dimensional stability and can better withstand the surging forces that occur without the need for additional stiffening elements, as in the case of a flat disk element.
  • Claims 5 to 8 relate to a multi-part baffle.
  • a central disc region which is connected in its edge region with a profile carrier element, which is provided with a leg is, which forms the side wall element.
  • a support element can be particularly easily adapted to the inner peripheral contour of the container and the central disc area.
  • T or angular support advantageous because they are available in different versions - as so-called.
  • Norm carrier - or - this is especially true for angle brackets - are easily produced in a variety of designs.
  • connection of the disc area to the profile carrier is particularly simple according to claim 7, since manufacturing tolerances, which relate to the container contour or the contour of the disc area, can be compensated in the simplest way for each other.
  • the overlapping arrangement also allows particularly easy to manufacture weld seams (fillet welds) and creates the necessary conditions for a screw in the overlap area.
  • Welded joints (claim 8) are particularly advantageous when alternately different loads are to be transported.
  • the welds completely close gaps in which cargo remains could accumulate. Cleaning is simplified.
  • Claim 9 relates to a baffle arrangement for a transport container with at least two baffles according to one of claims 1 to 9.
  • Such an arrangement is particularly suitable for transport containers such as tanker semi-trailers and tank containers, which have a volume of more than 15 m 3 .
  • a baffle arrangement with two or three baffles allows the prescribed volume division.
  • Three or four container areas (divisions) are defined. Two each between an end floor and a baffle and a third and possibly fourth in the middle between two baffles.
  • Claim 10 relates to a container with a baffle or baffle arrangement according to the invention, which has a cooling or heating area with a cooling or heating device on a container edge.
  • a cooling or heating region with a cooling or heating device on a container edge.
  • the cooling or heating regions often extend over a plurality of separated from the baffles areas of a container.
  • the increased convection and the enlarged recess in the floor area improves the material / load exchange during heating or cooling between the tank areas.
  • an improved mixing of the cargo over the entire container area takes place and the load is uniformly heated or cooled.
  • this effect is enhanced by the fact that in the edge region of the recess of at least one baffle a deflector is provided which deflects the convection generated during heating or cooling operation substantially transversely to the longitudinal direction of the container partially in the longitudinal direction.
  • a deflector is provided which deflects the convection generated during heating or cooling operation substantially transversely to the longitudinal direction of the container partially in the longitudinal direction.
  • Claim 12 relates to a tank container with a baffle according to the invention, a baffle arrangement according to the invention or a container according to the invention.

  • the support elements 46 shown here are as angle or L-carrier formed, the second leg 48 rests against the container wall 28.
  • the central disc portion 42 is formed curved, while the flat edge portion 44 thereof proceeds radially outward; approximately in a plane perpendicular to the longitudinal axis 14 (see FIG. 1 ) runs.
  • the bulging depth of the central disc region 42 in the direction of the longitudinal axis 14 is at least 100 mm, in order to ensure the required dimensional stability.
  • the central disc region is frusto-conical.
  • the baffle 40 is interrupted by a recess 16; in the sole region of the container 2, a larger recess 18 is provided, which is designed so that it is suitable as a maintenance pass and passable by a person.
