Abstract

PURPOSE: To prevent cracking of material by providing a heat insulating support for supporting at least one section of a vehicle and/or a vessel in at least substantially heat insulating mode with respect to other part thereby suppressing occurrence of thermal stress. CONSTITUTION: Bottom wall part in a section of a vehicle and/or a vessel being supported on a lower support 3 has a heat insulating support 1 provided with an upper means 2 having a low coefficient of friction so that it can slide thereon. The upper means 2 is preferably made of ULTE polyether imide resin so that it can withstand sufficiently against temperature of 200 deg.C and the weight of the relevant section during transportation of asphalt, or the like. An intermediate means 5 of e.g. a silicon rubber mat having heat insulation characteristics and pressure distribution characteristics, and an auxiliary lower means 6 of e.g. an EPDM rubber are also provided while being contained in a metallic holder 7 having an upstanding wall part 8.

Description

Detailed Description of the Invention

The invention relates to at least one material containing a substance which has to be maintained above the ambient temperature.
The present invention relates to a vehicle and / or a ship having two compartments inside.

Such vehicles and / or ships are generally well known. Within the compartment, for example, 2 degrees Celsius
A disadvantage of known vehicles and / or vessels (hulls) that have an internal compartment for transporting a certain substance to be maintained at a constant temperature of 00 degrees is that the internal compartment is fixed on the port side (mechanical). With the connection, the port side and the partition wall may be subject to very high material stress. In fact, if the chemical has a temperature of, for example, 200 degrees Celsius and the water surrounding the vessel has a temperature of, for example, 10 degrees Celsius, there is a temperature drop of as much as 190 degrees Celsius. The material stresses described above will result in cracks on the side and partition walls.

To overcome the above-mentioned deficiencies, it has already been proposed to fix the compartment to the deck instead of to the port side. As a practical matter, this solution has all the disadvantageous effects (cracks) of eventually material stresses on the deck as a result of the temperature difference between the deck and the compartment in communication with the surrounding air. So it didn't seem to be satisfying.

The object of the invention is to provide a vehicle and / or a vehicle having at least one compartment therein which is particularly suitable for transporting substances which have to be maintained above ambient temperature.
Or to provide a ship so that the material stresses on the vehicle and / or the ship as a result of temperature differences remain at acceptable levels.

To that end, a vehicle and / or a vessel of the kind indicated in the preamble comprises at least one compartment for at least a substantial heat to said vehicle and / or other parts of the vessel. It is characterized in that at least one thermally insulating support is provided which supports in an insulating manner.

In one embodiment of the vehicle and / or the ship according to the invention, the at least one thermally insulating support supports the at least one compartment in a free manner, ie the wall of the at least one compartment. It is characterized in that it is configured so as to support with a gap left between the part and the wall of the vehicle and / or the ship. Such a gap is particularly important because there will be no mechanical thermal contact between said at least one compartment and eg the wall of the vessel, eg as a result of the rocking movement of the vessel.

Another vehicle and / or ship according to the invention
In one embodiment, the at least one thermally insulating support is
The at least one compartment is characterized in that it comprises an upper means having a low coefficient of friction so as to be movable across the at least one thermally insulating support.

Another aspect of the vehicle and / or ship according to the invention
In one embodiment, the thermal properties of the upper means are such that the means is heat resistant to the high temperature at which the substance is to be maintained, the mechanical properties of the upper means being Characterized by the upper means being mechanically resistant to the weight load of the compartment. For example, if asphalt, which is to be maintained at a constant temperature of approximately 200 degrees Celsius, is transported in the interior compartment of a ship according to the invention,
The upper means must in all cases withstand the temperature of 200 degrees Celsius, and the upper means may, for example, be 40
It must be able to withstand the heavy load of tons.

Another vehicle and / or ship according to the invention
In one embodiment, the at least one thermally insulating support is
It is characterized in that it further comprises an intermediate means having heat insulating properties.

Another vehicle and / or ship according to the invention
One embodiment is characterized in that the intermediate means is compressible and has a pressure distribution characteristic.
The pressure distribution characteristics serve in particular to prevent deformation of the whole body, for example when point loads are applied to several points of the support.

Another vehicle and / or ship according to the invention
In one embodiment, the at least one thermally insulating support is
It is characterized in that it further comprises lower means having heat insulating properties. In the above-mentioned case where asphalt having a temperature of 200 degrees is transported, the thermal insulation property is
It is preferable that the lower means emits a temperature of about 70 degrees Celsius or lower at the bottom side surface.

Another vehicle and / or ship according to the invention
One embodiment is characterized in that said means are arranged at least partly in a holder.

The invention further relates to vehicles and / or vehicles according to the invention.
Or it relates to a heat insulating support which is clearly compatible with ships.

The present invention will be further described with reference to the figures shown in the drawings.

FIG. 1 shows a low coefficient of friction such that the bottom wall of a compartment of a vehicle and / or ship according to the invention supported on a lower support 3 can slide on it. 1 shows a thermally insulating support 1 provided with an upper means 2 having The composition of said upper means 2 with respect to composition is such that the temperature at which the asphalt should be maintained during transport, eg 2 degrees Celsius
The upper means is configured to withstand a temperature of 00 degrees and the weight of the compartment (approximately 40 tons). The upper means 2 is "ULTEM polyether imide resin"
Preferably, it is formed of a material well known in the name. This particular material has, for example, a tensile strength of 40 N / mm at 190 degrees Celsius of 3300 N / mm.
Bending stress, impact strength exceeding 36 Nm, 1.8
It has characteristics such as heat deflection temperature of 200 degrees Celsius at 2 N / mm.

Further, the intermediate means 5 is prepared,
The intermediate means is compressible and also has thermal insulation and pressure distribution characteristics. The intermediate means 5 is in this case, for example, a mat made of silicone rubber (for example a vinyl methyl silicone polymer synthesized with optimum resistance to aging). There is a complementary lower means 6 with heat insulating properties, for example EPDM rubbers (for example there are no double compounds in the main chain, as a result of which great temperature resistance and great cohesive strength are achieved. Ethylene propylene terpolymer). The whole of them is housed in a metal holder 7 with an upright wall 8, so that the rubber does not project laterally even under high weight loads.

2 and 3, corresponding parts are given the same reference numerals.
