Definitions

  • the invention relates to a heatable container.
  • Containers are known, which are used for storing and transporting different substances and provided with heating means for heating these substances.
  • the heating means comprise a cavity or heating mantle which is arranged in the casing of the container and to which heating medium, such as water, is supplied.
  • a problem with these solutions is that if high pressure must be maintained in said cavity - for example, to make the heating more effective or to use normal pressurized water from the supply network - material thicknesses of the cavity must be dimensioned quite large, which increases the manufacturing costs of the container considerably.
  • the container of the invention is characterized by what is disclosed in the characterizing part of the independent claim.
  • Other embodiments of the invention are characterized by what is disclosed in the other claims.
  • inventive embodiments are also disclosed in the specification and drawings of this application.
  • inventive contents of the application may also be defined in ways other than those described in the following claims.
  • inventive contents may also consist of several separate inventions, particularly if the invention is examined in the light of expressed or implicit sub-tasks or in view of obtained benefits or benefit groups. In such a case, some of the definitions contained in the following claims may be unnecessary in view of the separate inventive ideas.
  • Features of the different embodiments of the invention may be applied to other embodiments within the scope of the basic inventive idea.
  • the cavity, i.e. the heating mantle, of the container casing is provided with a heat-transfer channel, which is supplied with a second heat transfer medium used for heating a first heat transfer medium in the cavity.
  • a heat-transfer channel which is supplied with a second heat transfer medium used for heating a first heat transfer medium in the cavity.
  • Figure 1 is a schematic perspective view of a heatable container.
  • the container 1 may be a container intended for transporting and/or storing explosive substances, for example.
  • the container 1 may also be used for transporting and/or storing other substances that require heating.
  • Said substance may be liquid, gaseous or solid under NTP conditions.
  • the substance is a plant-protecting agent, which is in a solid state under NTP conditions. To discharge the substance from the container, it must be heated to become liquid. In other words, the container 1 is preferably heated only when needed.
  • the volume of the container 1 is 200 to 3000 litres, typically 1000 litres, for instance.
  • the container 1 comprises a casing 3, which is arranged to cover a container space.
  • the material of the casing 3 may be, for instance, metal, plastic, plastic composite or other similar material known per se.
  • the outer surface 11 of the container has a cylindrical form and its bottom is conical.
  • the bottom of the container 1 is provided with a discharge channel 13, through which the material in the container can be removed.
  • the casing may also have some other shape and the shape, number and position of the discharge channel and the filling channel may vary.
  • the container 1 may comprise support structures 15 or the like arranged outside the casing.
  • Figure 2 is a schematic, partially cross-sectional side view of the bottom part of a heatable container.
  • the casing 3 comprises a cavity space 4 for receiving a first heat transfer medium 6.
  • the cavity space 4 is separated from a container space 2 in such a manner that the substances contained in the cavity space 4 and the container space 2 cannot be mixed with one another.
  • the cavity space 4 is arranged in a casing part 8 forming the bottom of the container space 2, and from there it may extend as high as to a casing part forming the upper surface of the container 1. According to an idea, the cavity space 4 is restricted to the casing part 8 forming the bottom, possibly rising a small distance upwards from there.
  • the cavity space 4 may rise to the same height throughout the entire casing 3, but this is by no means necessary.
  • the first heat transfer medium 6 may be water, a water-glycol mixture, oil, etc.
  • the first heat transfer medium 6 may be added to the cavity space 4 through a filling hole, which is not shown in the figure for the sake of simplicity. If necessary, the first heat transfer medium 6 is removed from the cavity space 4 through a discharge channel 16.
  • the cavity space 4 is formed between an outer layer 9 and an inner layer 10 of the layered casing 3.
  • the layered structure may be provided in the entire casing 3 or only in some of its parts, in which case the other parts of the casing 3 have a different kind of structure.
  • the cavity space 4 is provided with a heat transfer channel 5, which is arranged to be connected to a heat source supplying a second heat transfer medium 7.
  • the heat transfer channel 5 is separated from the cavity space 4 as well as from the container space 2 in such a manner that the substances contained, firstly, in the heat transfer channel 5 and the cavity space 4 and, secondly, in the heat transfer channel 5 and the container space 2 cannot be mixed with one another.
  • said heat source is not shown in the figure for the sake of simplicity.
  • the second heat transfer medium 7 is circulated between the heat source and the heat transfer channel 5.
  • the second heat transfer medium 7 may have a similar or different composition with respect to the first heat transfer medium 6.
  • the second heat transfer medium 6 may be liquid, gaseous, such as water vapour.
  • the heat transfer channel 5 comprises a pipe, which is arranged to extend around the cavity space 4 in the casing part 8 forming the bottom of the container space, but not higher.
  • the heat transfer channel 5 is arranged to extend to the upper part of the cavity space 4.
  • the heat transfer channel 5 is arranged at parts of the cavity space 4 on the side walls of the casing, but not in the casing part 8 forming the bottom of the container space.
  • the heat transfer channel 5 may be made of metal, plastic or plastic composite, for instance.
  • the heat transfer channel 5 is integrated into the casing 3, in other words, the heat transfer channel 5 consists at least partly of the casing 3.
  • the structure of the heat transfer channel 5 is dimensioned for an internal pressure of at least 6 bar.
  • the heat transfer channel 5 may be made of a pipe with a pressure rating of PN16, for example.
  • the pressure in the heat transfer channel 5 does not load or stress the cavity space 4 or the casing 3.
  • the pressure of the first heat transfer medium 6 is directed to the last mentioned items, the pressure being independent of the pressure in the heat transfer channel 5.
  • the volume at a high pressure, such as 6 bar can be limited to be very small. According to an idea, said volume is 10 litres at most.
  • the temperatures applied may be quite high, for instance approximately +150°C.
  • a heat-insulating layer 12 which may be e.g. polyurethane or other heat-insulating material known per se, is arranged between the outer surface 11 of the container and the cavity space 4.
  • the heat-insulating layer 12 reduces heat losses of the container.
  • the heat-insulating layer 12 is not essential.
  • features disclosed in this application may be used as such, regardless of other features.
  • features disclosed in this application may be combined in order to provide different combinations.
  • the heatable container of the invention is characterized in that the cavity space is provided with a heat transfer channel, which is arranged to be connected to a source supplying a second heat transfer medium.
