DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device for a solid waste storage case which cuts a storage case to take out solid waste.

[0002]

2. Description of the Related Art Solid waste in the field of nuclear power includes combustibles,
Classified as flame retardant and non-flammable. These solid wastes are usually packed in plastic bags etc. for each type,
In order to facilitate handling such as transportation, they are collectively stored in a storage case having a shape-retaining property (see FIG. 3). And
After being temporarily stored in the storage case and then disposed of, solid waste is taken out of the storage case.

Conventionally, the operation of taking out solid waste from a storage case has been performed by a cutting device for solid waste. As shown in FIGS. 4 and 5, the cutting device transfers solid waste 53 from a platform 51 to a garbage case 52.
And pusher 5 is pushed by pusher hydraulic cylinder 54.
After the solid waste 53 in the refuse case 52 is fed to the lower portion of the cutter frame 56 by moving the solid waste 53 toward the cutter frame 56, the solid waste 53 is pressed by the cutting blade 58 while the solid waste 53 is pressed by the holding block 57. It is configured to cut waste 53. And
In the case of this configuration, if the solid waste 53 is put into the garbage case 52 while being stored in the storage case, the solid waste 53 can be cut together with the storage case. Can be taken out in a state.

[0004]

However, in the above-described conventional configuration, the solid wastes 53 are collectively stored in the storage case in a state of being bagged for each type.
There are the following problems.

[0005] The solid waste 53 has a suitable treatment method for each type. In other words, incineration treatment for combustible materials, incineration treatment and regeneration treatment for flame-retardant materials for flame-retardant materials, and volume reduction treatment and landfill treatment for incombustible materials are suitable for each type. It has been. Therefore,
When the solid waste 53 is taken out of the storage case,
It is preferable that the solid waste 53 be taken out in a bag-packed state so that the solid waste 53 is sorted into each type and immediately processed by each processing method. However, in the above-described conventional configuration, since the small solid waste 53 is taken out in a mixed state, the sorting operation of the solid waste 53 is performed in a longer time than in the case where the solid waste 53 is packed in a bag, and as a result, the processing is immediately performed. There is a problem that it is difficult to perform.

In the above-described conventional configuration, a large cutting energy is required to cut the solid waste 53 together with the storage case, and a mechanism such as a strong frame structure that only supports the cutting energy is required. As a result, the entire device becomes larger. In addition, solid waste 5
3 is liable to be generated in large quantities, and the metal of the solid waste 53 causes the cutting blade 58 to wear quickly, so that the cutting blade 58 needs to be frequently replaced.

In the field of nuclear power, solid waste is often treated in a glove box (generally, a narrow confinement box). Therefore, the above-described conventional large-sized apparatus is installed in a glove box. There is a problem that it is difficult.

Therefore, according to the present invention, only the storage case is cut and the solid waste 53 is packed in a bag so as to solve the above-mentioned problems such as a longer sorting operation and a larger apparatus. An object of the present invention is to provide a cutting device for a solid waste storage case that can be taken out in a state.

According to the above configuration, when the housing case is rotated around the central axis in a state where the housing case is fixed at a predetermined position, the housing case is cylindrical, so that the side wall of the housing case is rotated when the housing case is rotated. Always exists at the same position. Therefore, if the cutting blade is advanced by a predetermined amount so as to reach the side wall of the storage case, only the side wall of the storage case is cut,
With the rotation of the storage case, the entire side wall can be cut to divide the storage case. As a result, the solid waste in the storage case is taken out as a bag,
As a result, the sorting operation of the solid waste can be performed in the unit of the bag, and as a result, the sorting operation can be performed easily and in a short time.

Further, since only the side wall of the storage case can be cut, the cutting energy required at the time of cutting is greatly reduced as compared with the conventional case where both the storage case and the solid waste are cut. be able to. Therefore, since the cutting device can be configured with a mechanism that supports a small cutting energy, the cutting device can be downsized. Thereby, it can be easily installed in a glove box frequently used in the field of nuclear power. Furthermore, if only the side wall of the storage case is cut, generation of dust due to cutting of solid waste can be prevented, and early wear of the cutting blade can be prevented.

According to a second aspect of the present invention, there is provided the cutting device for a solid waste storage case according to the first aspect, wherein the case supporting means is movable forward and backward so as to contact the lower side wall of the storage case from both sides. A case elevating means for raising and lowering the housing case by advancing and retreating the lower pressing rollers, and a pair of lower pressing rollers; and abutting on both sides of an upper side wall of the housing case, which is located above the housing case and rises. And a case pressing means having an upper pressing roller arranged in a pair on the left and right sides in width. According to the above configuration, the housing case can be fixed and supported at a predetermined position with a simple configuration of the lower pressing roller and the upper pressing roller, so that the size of the apparatus can be further reduced.

According to a third aspect of the present invention, in the cutting device for a solid waste storage case according to the first or second aspect, the cutting blade moving means moves the cutting blade to a side wall at an upper end position of the storage case. It is characterized by moving forward and backward. According to the above configuration, since the bagging material is always present at the lower portion by its own weight in the rotating storage case, when cutting the side wall at the upper end position with the cutting blade, the possibility of cutting the bagging material is sufficiently low. can do.

The other end of 32 is rotated in the horizontal direction. Further, the vertical frame 13 is provided with a protective cover 33 made of acrylic resin on the side of the transport path of the storage case 4. Further, such a protective cover 33 is also provided around the case pressing mechanism 24. Each of the above-described driving devices is controlled by a control device (not shown).

The operation of the cutting device for a solid waste storage case in the above configuration will be described.

When the storage case 4 reaches the predetermined carry-in position of the cutting device, the traveling of the carrier 3 is stopped. Next, as shown in FIG. 1, the slide members 30 and 30 of the two case elevating mechanisms 28 and 28 are moved in the horizontal direction so as to approach each other.
With 0, the lower pressing rollers 29, 29 are advanced toward the storage case 4. Thereby, after each lower pressing roller 29 abuts on the lower part of the side wall of the housing case 4 from both sides, the housing case 4 is further advanced in the horizontal direction, so that the housing case 4 is a roller of the two lower pressing rollers 29. It will be lifted by the surface and rise.

When the storage case 4 rises, the storage case 4
The upper pressing rollers 25 are in contact with the upper side wall of the upper side.

The cutting edge of the storage case 4 is set at the uppermost position of the storage case 4. Therefore, even if the storage case 4 rotates, the bagging material 6 stored in the storage case 4 is always present at the lower part of the storage case 4 by its own weight, so that it is hardly cut by the cutting blade 18. As a result, when the storage case 4 is divided into three, the bagged material 6 is taken out while the solid waste 7 is stored.

When the housing case 4 is cut,
Dust such as chips is generated, and these dusts are taken into the dust collection case 19 together with the air, and are sucked through the dust collection hose 20.

Thereafter, when the cutting of the storage case 4 is completed, the cutting blade 18 is raised and the rotation is stopped.
Further, the rotation of the upper pressing rollers 25, 25 and the lower pressing rollers 29, 29 is stopped. Stopper member 3
2 is rotated in the lateral direction, and the contact state between the stopper member 32 and the housing case 4 is released. Then, the lower pressing rollers 29 are separated together with the slide members 30 by moving the slide members 30 of the case elevating mechanisms 28 horizontally so as to separate from each other. Thereby, the storage case 4 and the bag 6
Is transferred onto the carrier 3. Thereafter, as the transport trolley 3 travels, the storage case 4 and the bagging material 6 are moved.
Is carried out to the next sorting step, and solid waste 7 is combustible,
It is sorted into 6 units of bag stuff according to the types of flame retardant and non-combustible.

Is provided.

According to the above configuration, when the housing case 4 is rotated about the central axis in a state where the housing case 4 is fixed at a predetermined position, the housing case 4 has a cylindrical shape. It always exists at the same position during rotation. Therefore, if the cutting blade 18 is advanced by a predetermined amount so as to reach the side wall of the storage case 4, only the side wall of the storage case 4 is cut, and the entire side wall is cut with the rotation of the storage case 4. The storage case 4 can be divided. As a result, the solid waste 7 in the storage case 4 is taken out in the state of the bag 6, so that the sorting operation of the solid waste 7 can be performed in units of the bag 6, thereby simplifying the sorting operation. And in a short time.

Further, since only the side wall of the storage case 4 can be cut, the cutting energy required for cutting is greatly increased as compared with the conventional case where both the storage case 4 and the solid waste 7 are cut. Can be reduced. Therefore, since the cutting device can be configured with a mechanism that supports a small cutting energy, the cutting device can be downsized. Thereby, it can be easily installed in a glove box frequently used in the field of nuclear power. Furthermore, if only the side wall of the storage case 4 is cut, generation of dust due to cutting of the solid waste 7 can be prevented, and early wear of the cutting blade 18 can be prevented.

Although the present invention has been described based on the preferred embodiments, the present invention can be modified without departing from the spirit thereof.

That is, in the present embodiment, the housing case 4 is cut by the rotary cutting blade 18, but the housing case 4 may be cut by the fixed cutting blade 18. good. In the present embodiment, the housing case 4 is supported using four rollers including the upper pressing roller 25 and the lower pressing roller 29, but the housing case 4 may be supported by a plurality of rollers.
