DESCRIPTION:

BRIEF SUMMARY
The invention relates to the art of containers for handling material and, more particularly, a container for a carbon molecular sieve material and a device comprising these containers.


BACKGROUND OF THE INVENTION

Containers for a carbon molecular sieve material are known from DE-PS 26 52 486 and are used in a pressure alternation adsorption plant for the production of nitrogen.
A disadvantageous feature of prior containers for carbon molecular sieve material is that the carbon molecular sieve material initially has to be introduced into a special pack for transportation and then it has to be transferred into the containers of the pressure alternation adsorption plant. As a rule, the emptied disposable transportation containers cannot be used again but have to be disposed of since these contain residual quantities of the carbon molecular sieve material or, as the case may be, dust from the carbon molecular sieve material. Because of the high sensitivity of the carbon molecular sieve material to moisture, the transportation containers must be constructed in a hermetically sealed manner. The transfer of the carbon molecular sieve material has to be carried out with great care using appropriate special equipment. In this regard, contamination of the carbon molecular sieve material has to be prevented on transferring it or, as the case may be, introducing it into the container. In addition, one must ensure that a packing density is achieved on filling that is as high as possible.


SUMMARY OF THE INVENTION

The task that forms the basis of the invention is to provide a container that simultaneously serves as a transportation container and that can be used in an adsorption apparatus, that is assembled in a modular fashion, without the carbon molecular sieve material that is located therein, having to be transferred.
In accordance with the present invention, there is provided a container for a carbon molecular sieve material which is designed to permit transportation of the carbon material. The container preferably includes a hollow section that can be sealed such that gases are prevented or reduced from transversing the seal. The container preferably has a rectangular or square cross-section and the hollow section preferably has a circular cross-section. The hollow section of the container may be formed from a cast, an extrusion casting process, or some other means. For an extrusion casting process, the material of the container preferably consists of a metal such as aluminum which can be processed relatively simply by using an extrusion casting process. Metals such as aluminum have a low specific gravity and a high strength such that such metals can be easily machined and retained their rigidity and form during transportation. However, it is appreciated that other similar types of metals which have similar properties can also be used. Alternatively, the hollow section can be manufactured from a plastic material. Such plastic should have a relatively high strength to resist damage during transportation of the carbon materials.
In accordance with another feature of the preferred embodiment, the container includes screen structures for fixing or retaining the carbon material within the hollow section of the container. The screen structures are preferably located at the head end and the foot end of the hollow section. Preferably, the screen structures consist of a wire mesh, perforated sheeting, sintered metal or combinations thereof. The screen structures can be maintained at the two ends of the hollow section by bolts, adhesives, screws or the like. Preferably, the screens are maintained at the two ends of the hollow section by a clamping ring which rigidly affixes the screen between the clamping ring and the two ends of the hollow section.
In accordance with still another feature of the present invention, the container includes a covering structure which seals materials within the hollow section. The seal is designed to hermetically seal the hollow section and to prevent and reduce gasses from penetrating the
