Description

  The present invention relates to an apparatus for storing articles in a space maintained in an airtight state with respect to the outside in a sealed container from the space, for example, waste contaminated with radioactivity or microorganisms, in an airtight state with respect to the outside. It is related with the apparatus accommodated in an airtight container, without exposing to the external air from the space maintained in this.

  As a first example in which this kind of article storage device is required, there are experimental devices that handle radioisotopes. Such devices are installed in a hood that is provided with exhaust facilities and is always maintained at a negative pressure. The operation of the experimental apparatus is performed by an experimenter wearing rubber gloves, opening the shutter of the hood a little, and putting his hand in there. When waste such as unnecessary items or experimental samples is generated by the experiment, put it in a vinyl bag in the hood, seal the mouth of the vinyl bag, and temporarily take it out of the hood in a short time. A general method is to quickly put it in a waste container placed in the vicinity of the hood in advance and seal it with a lid.

  As a second example, radioactive waste generated by maintenance and inspection work at a nuclear facility such as a nuclear power plant is carried out in several stages depending on the pollution level, and is sequentially carried out while lowering the pollution level. . That is, if the work area with the highest radioactive contamination level is assumed to be area 1, an area with a lower contamination level is provided adjacently, this is designated as area 2, and area 3 with a lower level is further adjacent. Are sequentially arranged according to the contamination level. Finally, in the radiation control area, it is connected to an area where there is almost no contamination that a normal person can enter, and the area 1, the area 2, the area 3 and the area without the contamination are carried out in this order. Method of wiping the surface in each area or packing it with vinyl sheet or bag, etc. when carrying it out, carrying it out while lowering the contamination level of the surface one by one, and storing it in a sealed container such as a drum can prepared in advance in a pollution-free area Is generally done.

  As a third example, a method used in a case where even a very small amount such as plutonium causes a problem when leaking into a human breathing atmosphere will be described. Plutonium is usually handled in an airtight container called a glove box. Waste generated in this glove box is carried out by a method called “bag out”. This is because waste is inserted into a cylindrical vinyl bag with a bottom attached in advance to a part called a carry-out port provided at an appropriate place in the glove box, protrudes from the glove box, and the vinyl bag is attached with a high-frequency welder. It is a method of welding, cutting the welded portion with scissors or the like, separating it, and storing it in a waste container.

However, the above three examples have the following technical problems.
First, in carrying out waste by the method described in the first example, even though the entrance was sealed in the vinyl bag in the hood, this operation itself is highly likely to contaminate the surface of the vinyl bag, even in a short time. Nonetheless, transporting to an uncontaminated area outside the hood is not an acceptable method for handling plutonium or other highly hazardous items.

  In carrying out waste by the method described in the second example, before carrying out from area 1 to area 2, from area 2 to area 3, or from area 3 to a non-contaminated area, before carrying out to each area in advance. In addition, it is necessary to decontaminate the surface so that radioactive contamination of the surface does not contaminate the area to which it is carried out. Furthermore, it is necessary to carry out measures such as sealing the entrance in a new vinyl bag, confirming that the surface is free of contamination with a radiation measuring instrument, and carrying it out as many times as there are steps in the area. Need something.

  In the third example, it is necessary to cut and dispose of the waste to the size that can be accommodated in the vinyl bag beforehand, and when the remaining vinyl bag is reduced due to repeated welding and separation, it is the “bag change” method. Since it is necessary to replace it with a new one, the efficiency of carrying out the waste is poor and a lot of time and labor are required. Furthermore, bag-out and bag replacement require education for beginners, and even workers who regularly carry out bag-outs require careful attention and skill. In addition, there are many problems to be solved such as when there is always a risk of causing internal exposure by diffusing plutonium contamination in the vicinity when the bag is broken for some reason.

  In the present invention, when the waste or the like as described above is taken out from a space maintained in an airtight state with respect to a certain outside (hereinafter referred to as “airtight space”), stored in a sealed container, and sealed, Highly harmful radioactivity and other hazardous materials, such as plutonium, which can cause a large amount of internal exposure, and waste contaminated by them are completely exposed to the human breathing atmosphere. An object of the present invention is to provide an inexpensive device that can be stored in a container in a short time.

  In the present invention, in order to achieve the above object, the openings 1a and 2a of the hermetic space 1 and the hermetic container 2 are separated from each other while the hermetic space 1 in which contamination such as radioactivity exists and the external space where humans breathe are isolated. It was made possible to combine and separate. For example, waste generated in an isolation atmosphere for handling plutonium can be stored in a sealed waste container such as a drum can while being completely isolated from the external environment.

  That is, the article storage device for the sealed container according to the present invention is detachably fitted from the outside of the airtight space 1 to the opening 1a for article passage provided in the airtight space 1, and the opening 1a of the airtight space 1, The opening 2a of the airtight container 2 that is airtightly connected to the opening 1a, the opening 1a of the airtight space 1, and the opening 2a of the airtight container 2 are detachably fitted from the inside of the airtight space 1, respectively. A lid 4 on the airtight space 1 side and a lid 6 on the container side for hermetically closing the openings 1a and 2a.

  In such an article storage apparatus for an airtight container according to the present invention, the opening 2a of the airtight container 2 can be airtightly connected to the opening 1a of the airtight space 1, so that a contaminated article in the airtight space 1 can be opened. It can be accommodated in the sealed container 2 through the opening 2a of the sealed container 2 from 1a. Thereafter, the opening 2a of the hermetic container 2 is hermetically closed from the inside of the hermetic space 1 with the lid 6 on the container side, and the opening 1a of the hermetic space 1 is hermetically closed with the lid 4 on the airtight space 1 side. As a result, the contaminated article can be transferred from the airtight space 1 to the sealed container 2 and stored and sealed without leakage of the contamination to the outside. Thereafter, the opening 2 a of the sealed container 2 can be separated from the opening 1 a of the hermetic space 1, and the sealed container 2 can be removed from the hermetic space 1 and moved.

  In particular, by having a holding mechanism 10 that detachably holds the lid 4 of the opening 1a on the airtight space 1 side and the lid 6 of the opening 2a on the airtight container 2 side, the opening on the airtight space 1 side is provided. When the portion 1a and the opening 2a on the closed container 2 side are closed with the lid 4 and the lid 6, respectively, the surfaces exposed to the outside of the lid 4 and the lid 6 can be overlapped in the airtight space 1, Prevents the surface from being contaminated. Such a detachable holding mechanism 10 between the lid 4 and the lid 6 is detachably held by the interaction of magnetic force between the magnet 21 provided on one lid 4 and the magnetic body 12 provided on the other lid 6. There is something.

  Further, when the opening 2a of the sealed container 2 is detachably connected to the opening 1a of the hermetic space 1 and has a holding mechanism 9 for holding it, the opening 1a of the hermetic space 1 and the opening of the hermetic container 2 during operation are provided. After the cover 2a does not come off and is closed by the lid 4 and the lid 6, the holding mechanism 9 can be released and separated. As the holding mechanism 9 for the opening 1a of the airtight space 1 and the opening 2a of the sealed container 2, the magnet 21 provided on the lid frame 5 of the one opening 1a and the lid frame 7 of the other opening 2a. There is one that is detachably held by the interaction of magnetic force with the magnetic body 11 provided on the surface.

  As described above, in the article storage device for the sealed container according to the present invention, the connection of the sealed container 2 to the airtight space 1, the storage of the contaminated article in the sealed container 2, the opening 2 a of the sealed container 2 and the airtight space 1. A series of procedures of closing the opening 1a with the lid 4 and the lid 6 and finally separating from the airtight space 1 of the sealed container 2 can be easily performed without leaking contamination or the like.

In the present invention, the opening 2a of the hermetic container 2 is hermetically connected to the opening 1a of the hermetic space 1 so that the opening 1a, the lid 4 and the lid 6 of the opening 2a can be opened and closed on the hermetic space 1 side. The above-mentioned purpose has been achieved.
Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  In the present invention, as described above, waste generated in a radioactively contaminated area or the like is stored in a dedicated waste container. In this case, the feature is that this can be carried out while the contaminated space and the clean space are isolated. Here, as an example, a space that is airtightly isolated from the outside is defined as an airtight space, and the generated contaminated waste or the like is stored in an airtight container such as a drum can. Explained. The airtight space is always maintained at a negative pressure so that contaminated dust or the like does not leak outside.

  FIG. 1A and FIG. 2A show a state in which the airtight space 1 and the sealed container 2 are combined, and an article such as waste can be stored in the sealed container 2 from the contaminated airtight space 1. It shows a possible state. As shown in these figures, an opening 1a is provided in the floor of the airtight space 1, and the opening 2a of the hermetic container 2 is designed to be connected and attached thereto. The hermetic container 2 is moved up and down by a table 3 of a lifting device having a lifting function. Of course, when it is convenient to connect the hermetic container 2 to the airtight space 1 sideways, an opening 1 a can be provided on the wall side of the airtight space 1.

  FIG. 1A and FIG. 2A show a state in which the lid 4 that closes the opening 1a of the airtight space 1 and the lid 6 that closes the opening 2a of the sealed container 2 are overlapped and removed. The lid 4 and the lid 6 are removed to the airtight space 1 side in a state where they are coupled with magnets as will be described later. Both the lid 4 and the lid 6 are joined and lifted in an overlapped state, and are removed to the airtight space 1 side, whereby the inside of the hermetic container 2 and the inside of the airtight space 1 are opened to the openings 2a and 1a. Communicate through. Moreover, since the lower surface of the lid 4 and the upper surface of the lid 6 are overlapped, the airtight space 1 is not contaminated on these surfaces.

  Lid frames 5 and 7 are provided around the opening 2a of the hermetic container 2 and the opening 1a of the airtight space 1, respectively, and the lid frame 5 and the lid frame 7 are coupled and connected by a magnet as will be described later. Is done. That is, the lid frame 5 is attached to the opening of the floor of the airtight space 1 and has a structure that can be mechanically coupled to the lid 4. The lid frame 7 is attached to the upper edge of the sealed container 2 and has a structure that can be mechanically coupled to the lid 6.

  When an article such as waste is moved and stored from the airtight space 1 to the sealed container 2 and the sealed container 2 is full, the lid 4 and the lid 6 remain connected to each other, and they are attached to the lid frame 5 of the opening 1a. Are fitted into the lid frame 7 of the opening 2a and rotated 60 ° in any direction, and the lid 4 and the lid frame 5 and the lid 6 and the lid frame 7 are mechanically coupled to each other. A handle 8 for facilitating the rotation operation is provided on the upper surface of the lid 4 that closes the opening 1 a of the airtight space 1. Details of the connecting mechanism between the lid 4 and the lid frame 5 and between the lid 6 and the lid frame 7 will be described later.

  Next, when the coupling of the lid 4 and lid 6 and the lid frame 5 and lid frame 7 by the magnet is released and separated, and the table 3 is lowered, the state shown in FIGS. 1 (b) and 2 (b) is obtained. In this state, the opening 6 a of the sealed container 2 is closed by the lid 6, the opening 1 a of the hermetic space 1 is closed by the lid 4, and the sealed container 2 is separated from the hermetic space 1. As a result, the sealed container 2 that contains the article and is sealed with the lid 6 can be transported to a predetermined waste storage facility. Until the lid 4 and the lid 6 are separated, since the lower surface of the lid 4 and the upper surface of the lid 6 are overlapped, those surfaces are not exposed to the air in the hermetic space 1, and therefore their The surface is uncontaminated and does not spread the contamination when exposed to the outside air.

  FIG. 3 is an enlarged view of the sections of the lids 4 and 6 and the lid frames 5 and 7 that are coupled and separated. FIG. 5 is an enlarged view of FIG. The lids 4 and 6 and the lid frames 5 and 7 will be described in more detail with reference to these drawings. Note that the handle 8 is not shown in FIG.

  A holding mechanism 9 is incorporated outside the lid frame 5 attached around the opening 1a of the airtight space 1. The holding mechanism 9 attracts and holds the upper surface of the lid frame 7 of the hermetic container to the lower surface of the lid frame 5 of the hermetic space 1 by a magnet, and the lid frame 7 of the hermetic container 2 has a magnetic body such as an iron plate. 11 is embedded. On the other hand, a similar holding mechanism 10 is also incorporated in the lid 4 that closes the opening 1a of the airtight space 1, and a magnetic body 12 such as an iron plate is attached to the lid 6 of the sealed container 2 correspondingly. Details of the holding mechanisms 9 and 10 will be described later. The holding mechanism 10 provided on the lid 4 is covered with a cover 19.

  The inner periphery of the lid frame 5 provided around the opening 1a of the airtight space 1 has a convex portion 14 partially provided in the circumferential direction, and the outer periphery of the lid 4 is also provided in the circumferential direction. It has the convex part 13 provided partially. As is apparent from FIG. 5, three convex portions 14 provided on the inner periphery of the lid frame 5 are provided at an interval of 120 ° on the inner periphery of the lid frame 5. It extends over a length of less than 60 ° in the circumferential direction. Three convex portions 13 provided partially on the outer periphery of the lid 4 are also provided on the outer periphery of the lid 4 at intervals of 120 °, and the length of the convex portions 13 is less than 60 ° in the circumferential direction of the outer periphery of the lid 4. Spans the length.

  Similarly, the inner periphery of the lid frame 7 provided around the opening 2 a of the sealed container 2 has a convex portion 16 provided partially in the circumferential direction, and the outer periphery of the lid 6 also has the circle. It has a convex portion 15 provided partially in the circumferential direction. As is apparent from FIG. 5, three convex portions 16 provided on the inner periphery of the lid frame 7 are provided at an interval of 120 ° on the inner periphery of the lid frame 7. It extends over a length of less than 60 ° in the circumferential direction. Three convex portions 15 partially provided on the outer periphery of the lid 6 are also provided on the outer periphery of the lid 6 at intervals of 120 °, and the length of the convex portions 15 is less than 60 ° in the circumferential direction of the outer periphery of the lid 6. Spans the length.

  The lid 4 and the lid 6 are superposed in advance so that the positions of the convex portions 13 and 15 coincide with each other in the vertical direction, and are attracted and held. The lid frame 5 and the lid frame 7 are also connected and held in advance so that the positions of the convex portions 14 and 16 coincide with each other in the vertical direction. When the lid 4 and the lid 6 thus sucked and held are inserted into the openings 1a and 2a into which the lid frame 5 and the lid frame 7 are coupled, the convex portions 13 and 15 are formed into the lid frames 5 and 7 respectively. The projections 14 and 16 are inserted so as to be located at portions where no projections 14 and 16 are present. At this time, the convex portions 13 and 15 of the lids 4 and 6 are inserted deeper than the convex portions 14 and 16 of the lid frames 5 and 7. Next, by rotating the combined lids 4 and 6 by 60 ° in either direction, the convex portions 13 and 15 of the lids 4 and 6 are positioned at the convex portions 14 and 16 of the lid frames 5 and 7. The lid 4 is mechanically coupled to the lid frame 5, and the lid 6 is mechanically coupled to the lid frame 7.

  The lid 4 that closes the opening 1a of the airtight space 1 and the lid 6 that closes the opening 2a of the sealed container 2 are overlapped as described above, and are adsorbed and held by the holding mechanism 10, but at that time, FIG. As shown in FIG. 6 (b), in order to fix both the lids 4 and 6 in the circumferential direction, a projection 17 and a hole 18 fitted to each other are provided. When the lid 4 and the lid 6 are overlapped and rotated by the handle 8 (see FIG. 5) while being attracted and held by the holding mechanism 10, the rotation resistance causes a shift, and the positions of the convex portions 13 and 15 change. And prevent the lids 4 and 6 from being inadvertently separated.

  FIGS. 4A and 4B are conceptual diagrams showing the structure and operation of a holding mechanism using a permanent magnet as an example of the holding mechanisms 9 and 10. For example, in the exemplary holding mechanisms 9 and 10 shown in FIG. 4, a magnet 21, which is a partially cylindrical permanent magnet, is fitted sideways into a yoke 22 made of a cylindrical material that is horizontally oriented as a whole. 21 is rotated at least 90 ° by an external lever operation or the like. The yoke 22 is divided into two on both sides, and a non-magnetic material 23 is inserted between the both sides of the yoke 22 above and below. The main body side of the holding mechanisms 9 and 10 is provided on the lid 4 and the lid frame 5 of the airtight space 1. On the other hand, magnetic bodies 11 and 12 such as iron plates are embedded at positions corresponding to the main body side of the holding mechanisms 9 and 10 of the lid 6 and the lid frame 7 of the sealed container 2.

  As shown in FIG. 4A, when the magnetic poles S and N of the magnet 21 are oriented sideways in the yoke 22, magnetic paths are formed above and below the magnetic poles S and N along the yoke 22. Since the magnetic path is insulated by the nonmagnetic material 23 in the upper and lower portions of the yoke 22, the magnetic path leaks up and down the yoke 22 at the upper and lower ends of the yoke 22, respectively. Therefore, on the lower end side of the yoke 22, a magnetic path is formed through the magnetic bodies 11 and 12 embedded in the lid 6 and the lid frame 7 of the sealed container 2, and the magnetic bodies 11 and 12 are magnetized via the yoke 22. 21 is aspirated. On the other hand, as shown in FIG. 4B, when the magnetic poles S and N of the magnet 21 are vertically oriented in the yoke 22, there are magnetic paths along both sides of the magnetic poles S and N along the yoke 22. Although formed, this magnetic path is formed only along the yoke 22 on both sides of the magnet 21 and hardly leaks outside the yoke 22. Accordingly, the magnetic body 11 embedded in the lid 6 or the lid frame 7 of the sealed container 2 is not attracted by the magnet 21.

  As described above, the holding mechanisms 9 and 10 include the magnet 21 provided on the lid 4 and the lid frame 5 of the opening 1 a of the airtight space 1 and the magnetic bodies 11 and 12 provided on the lid 6 and the lid frame 7 of the hermetic container 2. There are some which hold the lid 6 and the lid frame 7 detachably by the interaction of magnetic force. In the examples of the holding mechanisms 9 and 10, a permanent magnet that is rotated and operated is used as the magnet 21. However, a fixed electromagnet that is excited and demagnetized by energization and deenergization may be used as the magnet. .

Next, an operation method of the article storage device will be described with reference to FIG. In the figure, the handle 8 is not shown.
FIG. 6 (a) is a diagram showing the state shown in FIG. 1 (a), FIG. 2 (a) and FIG. That is, the lid frame 5 of the hermetic space 1 and the lid frame 7 of the hermetic container 2 are superposed and adsorbed and held in an airtight manner by the above-described holding mechanism 9 incorporated in the lid frame 5. The lid 4 and the lid 6 of the hermetic container 2 are superposed and attracted and held by the holding mechanism 10 described above. As shown in FIG. 5, the projections 14 and 16 of the lid frame 5 of the hermetic space 1 and the lid frame 7 of the hermetic container 2 are previously aligned with the hermetic space 1 so that the positions thereof coincide with each other in the vertical direction. Connect.

  The lid 4 and the lid 6 are overlapped in advance so that their convex portions 13 and 15 coincide. In this state, the convex portions 13 and 15 of the lid 4 and the lid 6 are aligned with the portions of the hermetic space 1 where the convex portions 14 and 16 of the lid frame 5 and the lid frame 7 of the sealed container 2 are absent. The lids 4 and 6 overlapped at this position are inserted into the lid frames 5 and 7, and the convex portions 13 and 15 of the lids 4 and 6 are fitted until they are below the convex portions 14 and 16 of the lid frames 5 and 7. . Thereafter, the overlapped lids 4 and 6 are rotated by 60 ° in any direction, and the convex portions 13 and 15 are slid under the convex portions 14 and 16 of the lid frames 5 and 7. As a result, the lids 4 and 6 are connected to the lid frames 5 and 7 as shown in FIG. 6 (b).

In this state, the magnet 21 (see FIG. 4) of the holding mechanisms 9 and 10 is rotated 90 degrees to release the holding by the holding mechanisms 9 and 10, and the lids 4 and 6 and the lid frames 5 and 7 are separated. It is. As a result, the sealed container 2 is separated from the airtight space 1 as shown in FIG. 6c, and the sealed container 2 can be transported and moved.
On the contrary, when the opening 2a of the next new empty hermetic container 2 is coupled to the opening 1a of the floor of the airtight space 1, the operation may be performed in the reverse procedure to the separation.

  FIG. 7 is a view showing an example of the hermetic container 2. FIG. 7 (a) shows a partially exploded state, and FIG. 7 (b) shows an assembled state. The sealed container 2 is a double-structured container having an inner container 20 that can be inserted therein. In the illustrated example, the lid frame 7 is attached to the inner container 20. The lid frame 7 may be attached to the sealed container 2. As described above, the lid 6 of the sealed container 2 is fitted into the lid frame 7 and fixed. After the inner container 20 with the lid 6 is fitted and stored in the sealed container 2, a protective lid 25 is further put on the lid 6.

  Such an article storage device simplifies the structure, and the operation of coupling and separation is simple, quick, and different types of operations such as the operation of the holding mechanisms 9 and 10 and the rotation of the lids 4 and 6 do not cause erroneous operations. I am doing so. In addition, by simplifying the structure on the side of the closed container 2 that is used in large numbers, the price can be reduced. Further, even in long-term storage containing radioactive waste, the connection is a mechanical connection, so that the reliability is high.

  In the above example, the airtight space 1 is a contaminated isolation space, and the contaminated waste is moved to the sealed container 2 and sealed. On the contrary, the present invention is a clean room for preventing dust and the like because the airtight space 1 forms a fine circuit pattern, and can be used as a device for taking out the product into the sealed container 2. Of course.
