In the figure, reference numeral 81 denotes a drum fixture for placing the waste storage drum 80 in place, and reference numeral 100 denotes a control panel for operating and controlling the configuration of the present invention.

When describing the waste treatment process by the radioactive metal waste compression storage device of the present invention according to the above configuration in more detail as follows.

As shown, the present invention is intended to compress and treat only metal waste, especially of radioactive waste.

However, since metal waste may have a considerable difference in size, the size that can be input through the inlet 21 can be input as it is. The metal waste having a size larger than the inlet 21 is formed to be smaller than the inlet 21 by cutting.

Radioactive metal wastes of the size that can be input through the inlet 21 are weighed by a certain weight using a meter (not shown) having a certain volume of weighing bin.

The metal waste weighed by a predetermined weight is introduced into the waste container 20 as shown in FIG. 6 through the inlet 21.

When the metal waste is injected into the waste container 20, the inlet 21 is locked and the first cylinder 21 of the first driver 20 is driven as shown in FIG. 7.

When the first press plate 22 is advanced by the driving of the first cylinder 21, the metal waste introduced into the waste container 20 starts to be gradually compressed.

Compression by the first cylinder 21 is performed to advance the first pressing plate 22 in the longitudinal direction by a predetermined distance until the interval between the first pressing plate 22 and the lifting plate 52 becomes a predetermined interval. do.

In the state where the first pressing plate 22 is advanced, as shown in FIG. 8, the second cylinder 31 is driven to advance the second pressing plate 32 by a predetermined distance in the width direction of the waste container 10.

Like the first press plate 22, the second press plate 32 also moves the set distance so that the first-compressed metal waste is secondarily compressed in the width direction.

Therefore, the metal waste compressed by the first cylinder 21 and the second cylinder 31 is molded in the same length and width.

The metal waste compressed in the longitudinal direction and the width direction is compressed upward by the third pressing plate 42 by the driving of the third cylinder 41 as shown in FIG. 9.

The compression by the third pressing plate 42 is performed until the driving pressure of the third cylinder 41 reaches the set value.

That is, since the metal waste compressed by the first press plate 22 and the second press plate 32 have different densities, the third press plate (3) may be set to a constant value by the driving pressure by the third cylinder 41. 42) make the density of metal waste constant.

In this manner, the metal waste is compressed by the first pressing plate 22, the second pressing plate 32, and the third pressing plate 42. The second pressing plate 32 and the third pressing plate 42 are sequentially returned to the original position.

When the first pressing plate 22, the second pressing plate 32, and the third pressing plate 42 are retracted as described above, the pressed state of the compressed metal waste 90 is released as shown in FIG. 10.

Subsequently, when the fourth cylinder 51 of the gate elevating unit 50 is driven to raise the elevating plate 52 by a certain height, the other end surface of the waste accommodating portion 10 corresponding to the first press plate 22 on one side is raised. The formed gate 12 is opened.

Subsequently, when the fifth cylinder 51 of the blowout part 60 fixed to the first pressing plate 21 is driven, the push plate 52 provided on the same plane as the first pressing plate 21 has a predetermined length. Move forward.

When the push plate 52 is advanced, the compressed waste is pushed out by the push plate 52 as shown in FIG. 11, and the metal waste 90 compressed into the waste tray 13 through the gate 12 is disposed in the waste container. Take out outside 10).

When the compressed metal waste 90 is taken out to the waste tray 13, the push plate 52 is returned to its original position, and the lifting plate 52 is returned to the original position together with the first press plate 21, and the next metal waste is returned. Ready for compression.

12 is an operation structural diagram illustrating a state in which the compressed metal waste taken out from the extraction unit by the transfer unit in the radioactive metal waste compression storage device according to the present invention to the drum for storing the waste.

The metal waste thus extracted is attached to the top surface of the compressed metal waste to the electromagnet plate 74 fixed to the tip of the arm 53 by the robot of the transfer unit 70, and the metal attached and fixed to the electromagnetic plate 74 The waste is moved to the waste storage drum 80 to be sequentially loaded.

The transfer part 70 of the present invention is to raise or lower the metal waste drawn out to the waste tray 13 by attaching the upper end to the electromagnet plate 74 by supplying or interrupting power to the electromagnet plate 74. By rotating and moving to the waste storage drum 80 so that the metal waste in the waste storage drum 80 can be sequentially loaded while being separated from the electromagnet plate (74).

As described above, when the metal waste is compressed according to the present invention, since the metal waste can be downsized to a uniform density, the filling efficiency in the waste storage drum 80 can be further improved.

That is, the smaller the loading size of the metal waste, the more the filling efficiency in the waste storage drum 80 is further improved, so that a larger amount of waste treatment is possible.

In particular, the present invention can be installed in a minimum space by reducing the overall size of the installation to maximize the space utilization.

On the other hand, by weighing the metal waste is to be constantly put into the weight of the compressed metal waste is made uniform so that it is possible to accurately adjust the weight of the waste storage drum (80).
