Reducing the volume of compressible waste and packaging it in containers is convenient and inexpensive for transportation to dumping sites and storage of waste that cannot be dumped. Radioactive waste is a particularly necessary item. Radioactive waste has a very large effect on the human body if dumped as is, so it is stored and managed in storage and disposal facilities. Among these, especially compressible solid waste is reduced in volume and packed into 200 drums. This involves putting the solid waste into a drum and compressing it with the piston of a hydraulic press, which is repeated seven to eight times. Hydraulic presses are used that have a capacity of about 20 tons to 100 tons, and the diameter of the piston is slightly smaller than the inner diameter of the drum. Solid wastes subject to volume reduction include paper and cloth rags used in decontamination work;
These items include vinyl sheets used to prevent the spread of radioactive materials during maintenance and disassembly work, protective gear worn by workers, and other items no longer needed at nuclear facilities. These solid wastes are compressed using a hydraulic press to reduce their volume to about 1/2 to 1/6.

The volume of radioactive waste whose volume has been reduced in this way continues to increase year by year with the development of the nuclear power industry, and as of 1981, more than 200,000 drums were stored. It is difficult to store the ever-increasing amount of radioactive waste in existing storage and disposal facilities. Recently, a plan was made to dispose of some of the drums by dumping them into the ocean, but as long-term safety has not yet been established, it is difficult to gain the understanding of local residents. Therefore, in order to reduce the total amount of drums, refilling of radioactive waste is being carried out.

Compressible solid waste is often fibrous;
It is highly elastic, so even if it is compressed with a hydraulic press, it will quickly return to its original shape if left alone. As a result, solid waste builds up on the drum, making it difficult to cover and seal the drum. The workers have no choice but to remove the solid waste that has piled up and then cover it with a lid to seal it. Therefore, even if solid waste is refilled, it is hardly implemented.

このように廃棄物処理容器としてドラム缶のみ
を用いたのでは圧縮可能な廃棄物を十分減容して
詰め込むことができないという欠点があつた。
As described above, when only drums are used as waste treatment containers, there is a drawback that compressible waste cannot be sufficiently reduced in volume and packed.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to provide a waste treatment container that can prevent compressed waste from expanding during treatment operations and further reduce the volume of waste when it is packed. It's about doing.

3 is the inner lid. This inner lid 3 is a plate-shaped body as shown in FIG. 2, and the left and right outer peripheries 4 are
It is formed to have approximately the same curvature as the inner circumference of the container 1, and is also shrunk in the left-right direction to be smaller than the inner diameter of the container 1 as a whole. The inner lid 3 has a crushed portion 5 at its center, and this crushed portion 5 is formed to be more raised than the outer edge 6. When the crushed portion 5 is crushed and becomes flat, the left and right outer circumferences 4 are The size is such that it can be pressed against and fixed to the inner wall of the When the inner lid 3 is pushed by a piston (not shown) of a hydraulic press and the volume of the waste 2 is reduced and the internal pressure becomes high, the internal pressure increases at the outer edge 5.
It is formed so that it collapses when the pressure of the hydraulic oil of the hydraulic press exceeds a predetermined level. The inner lid 3 also has a cut surface 7 at the center of its outer edge 6 that reaches from the vicinity of the crushing part 5 to the outer circumference 4. Each has the function of diffusing in the left and right directions.

First, a worker puts an appropriate amount of waste 2 into the container 1, then places the inner lid 3 on top of the waste 2 and operates the hydraulic press. The piston of the hydraulic press inserts the inner lid 3, and the inner lid 3 pressurizes and compresses the waste 2. As the piston moves further down, the volume of the waste 2 is reduced and the internal pressure increases. When the pressure of the hydraulic oil of the hydraulic press increases and reaches a predetermined pressure, the internal pressure acting on the outer edge 6 causes the crushed portion 5 to collapse and become flat. At this time, the outer periphery 4 of the inner lid 3 spreads in the left-right direction and comes into pressure contact with the inner wall of the container 1. When this condition is reached, the operator reverses the operation of the hydraulic press and raises the piston. The inner lid 3 is frictionally engaged with the inner wall of the container 1 and suppresses expansion against the internal pressure of the waste 2.

作業員は上記した作業を数回繰り返して廃棄物
2を容器1内に満し、最後に上蓋(図示せず)を
被せて密閉する。
The worker repeats the above-mentioned operation several times to fill the container 1 with the waste 2, and finally covers the container 1 with a top lid (not shown) to seal it.

このようにして廃棄物を容器に詰め込んだた
め、本実施例では従来と比べて約3〜5倍程度の
減容率を得ることができた。
Since the waste was packed into the container in this manner, the present example was able to obtain a volume reduction rate of about 3 to 5 times compared to the conventional method.

なお、中蓋の外周は切断面の数を増して3方向
または4方向に拡張させることもできる。切断面
は必ずしも図示の如くする必要はなく、単なる切
込みであつてもよい。
Note that the outer periphery of the inner lid can be expanded in three or four directions by increasing the number of cut surfaces. The cut surface does not necessarily have to be as shown in the figure, and may be a simple cut.

また、中蓋の外周を突起状にして圧潰部が潰れ

得ることができる。
In addition, it would be even better if the outer periphery of the inner lid is made into a protruding shape so that when the crushing part is crushed, the protrusion on the outer periphery bites into the inner wall of the container, or a rubber lining is applied to the outer periphery to increase the coefficient of friction with the inner wall. A high volume reduction rate can be obtained.

As explained above, according to the present invention, the inner lid frictionally engages with the inner wall of the container to prevent the waste from expanding, so that the waste can be sufficiently reduced in volume and packed into the container.

なお、本実施例では容器としてドラム缶を使用
したがその他の形状例えば4角形状の容器を使用

Although a drum is used as the container in this embodiment, other shapes such as square containers can also be used.
