Description

[Detailed Description of the Invention] The present invention relates to a container for long-term storage of an adsorbent (hereinafter referred to as an adsorbent) having excellent adsorption performance, such as activated carbon.

Adsorbents very well adsorb moisture, odors, etc. in the atmosphere and deteriorate, so contact with the atmosphere must be prevented except when necessary.

Conventionally, adsorbent was sealed in a plastic bag or the like, and then transported or temporarily stored in a container as shown in Figure 1. However, outside air may enter through the gap between the main container and the lid, making it difficult to store the plastic bag properly. There was a risk that the internal adsorbent would deteriorate due to deterioration, fraying, incomplete sealing, etc.

The present invention attempts to propose a storage container that eliminates this problem, and its structure consists of an airtight container with an adsorbent inlet/outlet on one side, and a double airtight seal for the inlet/outlet of the container. A lid that is airtight and has at least a transparent part, and a two-layer space with an appropriate thickness in the depth direction of the container, and an opening on the top and a second layer on the bottom inside the lid. a first space having a first ventilation hole leading to the second space, and a second space having the first ventilation hole at the bottom toward the container side and a second ventilation hole toward the upper container side. and a check valve provided on the container wall closest to the second vent, the first space filled with a moisture absorbent, and the second space filled with an adsorbent. According to the storage container according to the present invention, the entrance and exit of the container containing activated carbon is sealed in a sealed manner, and layers of dehumidifier and adsorbent are provided in that order inside the container, so that in case of damage to the inside or outside of the container, This has the advantage that even if air is vented, only the air that has been sufficiently dehumidified and purified by adsorbing harmful gases enters, so that the stored items will not deteriorate.

Next, one embodiment of the present invention will be described with reference to the drawings.

In FIGS. 2 and 3, 1 is a container body, and 3 is a dehumidifier layer (for example, silica gel) filled in a space provided inside the lid.

4 is an adsorbent layer (activated carbon is suitable) filled in a second space provided on the container side, and the dehumidifier layer is the first ventilation hole 5.
It has a structure that allows ventilation through.

6 is a second ventilation hole provided between the adsorbent layer and the inside of the container.

7 is an adsorbent layer lid. 8 is an external packing, 8a is a lid side packing, 8b is a main body side packing, 9 is an internal packing, 9a is a lid side packing, 9b is a main body side packing, and the external packing 8 and the internal packing 9 surround the opening. It is a provision.

10 is a container, 11 is a transparent part provided in a part of the lid 2 for observation, 12 is a pressure regulating mechanism, 13 is a check valve, and 14 is a spring that normally pushes the check valve 13 and closes the pore 15. I'm here.

15 and 16 are pores, 17 and 18 are gaskets, 19 are metal fittings for fixing the lid to the main body, and 20 are wheels for movement.

To use the container of the above embodiment, a container 10 containing an adsorbent that requires long-term storage is placed in the container body 1, and the lid 2 is closed.

In this way, even if outside air enters through the gap between the container body 1 and the lid 2 as shown by arrow A in Figure 2, the internal gasket 9
The moisture in the outside air is removed here because it flows as shown by arrow B into the dehumidifier layer 3 which has lower ventilation resistance than the adsorbent layer lid 7 portion.

Then, in order to further enter the inside of the container body 1, it passes through the adsorbent layer 4 as shown by arrow C, and after the odor, solvent vaporized gas, etc. in the outside air is adsorbed and removed, a second ventilation hole 6 is opened as shown by the arrow. The outside air that reaches the opening is clean, free of moisture and harmful gases, and is completely harmless to the contents.

Therefore, the container 10, which is sensitive to contamination by outside air, can be stably stored for a long period of time.

In order to improve the effect of passing through the dehumidifier layer 3 and adsorbent layer 4, the first vent hole 5 is opened downward and the second vent hole 6 is opened upward, so that the outside air that enters can be removed. It is made so that it always passes through the dehumidifier layer 3 and the adsorbent layer.

In addition, in order to confirm from the outside the degree of outside air that has entered during long-term storage, the lid 2 is provided with a transparent part 11 made of an acrylic resin plate, etc., so it can be determined from the amount of discoloration of the dehumidifier layer 3 (discoloration due to moisture absorption). be able to.

Note that the transparent portion may be such that the entire lid 2 is transparent.

When the internal pressure of the pressure regulating mechanism 12 increases, the check valve 13 pushes the spring 14 and opens outward to release the internal pressure through the pores 15 and 16 until it becomes equal to the external pressure.

As specifically explained in the embodiments, the present invention has the following effects because the dehumidifier and the adsorbent are arranged in this order at the entrance/exit of the storage container.

(1) It is possible to store adsorbents with extremely excellent adsorption performance, such as activated carbon, for a long period of time.

(1 to 3 years) (2) The degree of deterioration of the dehumidifier layer filled inside can be easily seen from the transparent part of the lid, so the storage condition of the stored items can be estimated.

(3) Since a pressure regulating mechanism is provided, it is possible to prevent an abnormal increase in internal pressure.

(4) Since the pressure regulating mechanism is located close to the lid, even if gas flows inside the container, it will flow in the same direction as arrow A, and there will be little change in the gas near the contained object 10. .

(5) Also, due to the pressure regulating mechanism, the gas flow direction is changed from A-B to C.
There is no backflow in the -+D-+E route, and the activated carbon and adsorbent do not work wastefully.
