Here, the fastening hole array is formed along the circumferential direction of the packaging drum (D1) is composed of a plurality of fastening holes 172 to which a predetermined fastening member is fastened.

In the present embodiment, each 200 liter packaging drum D1 containing 100 liters of the drum D2 and 320 liter packaging drum D1 containing the 200 liters of the drum D2 are respectively circumferentially along the circumferential direction. Four fastening holes 172 are formed.

Therefore, by coupling the fixing part 176 to the fastening hole 172 formed on the bottom surface of the transfer unit 170 with a predetermined fastening member 174, it is possible to fix the packing drum (D1).

In addition, when the packing drum D1 fixed to the transfer unit 170 is changed, after the fastening member 174 is released and the fixing part 176 is released, the fixing part 176 is arranged along the other fastening hole array. ) Can be used universally for the various specifications of the packaging drum (D1).

On the other hand, unlike the present embodiment, it is also possible to have a separate transfer unit 170 for each size of the packing drum (D1).

Referring to Figure 6, the operation of the drum compressor according to the present invention will be described.

First, as shown in FIG. 6A, the packing drum D1 is fixed to the inside of the main body unit 110 through the first door 122. The position of the packaging drum D1 on the main body unit 110 may be determined by the limit switch 190.

Next, as shown in (b) of FIG. 6, a protective sleeve 150 for protecting the inner circumferential surface of the packing drum D1 is fixed to the coupling plate 162 and guided by the guide part 164. It moves downward and is fitted to the inner circumferential surface of the packaging drum D1.

Then, as shown in (c) of Figure 6, the receiving drum (D2) containing the radioactive waste is introduced into the body unit 110 through the second door (124).

And, finally, as shown in Figure 6 (d), the compression unit 140 connected to one end of the piston portion 132 of the drive unit 130 is moved downward to apply a compressive force to the receiving drum (D2). As a result, the accommodation drum D2 is compressed inside the packaging drum D1.

On the other hand, the process of Figure 6 (c) and (d) is repeated a few more times for the compression of another receiving drum (D2), and after all the compression process is protected in the reverse process of Figure 6 (b) Sleeve 150 is moved to the top to be removed from the packaging container, the compression unit 140 also moves to the top in the reverse process of Figure 5 (d).

Then, by pulling out the packaging drum (D1) mounted on the transfer unit 170 to the outside to complete the compression process.

On the other hand, if the size of the receiving drum (D2) is changed according to the packaging drum (D1) of a different size on the transfer unit 170 according to this, and the compression unit 140 and the protective sleeve 150 is accommodated changed Corresponding to the size of the drum D2, it can be replaced and compressed.

Up to now, the storage drum (D2) has a capacity of 100 l, 200 l, the packaging drum (D1) has illustrated a case corresponding to the corresponding 200 l, 320 l capacity, but the capacity of the accommodation drum can be variously modified, Various types of drums may be configured in three or more forms, such that the drum compressor may be used universally.

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, those skilled in the art can make modifications without departing from the spirit of the present invention, and such modifications are possible. Belongs to the scope of.

Drum compressor according to the present invention having the above configuration has the following effects.

First, by configuring the compression unit to be detachable from the drive unit, even if the size of the receiving drum to be compressed changes, there is an advantage that the compression unit can be easily replaced by a corresponding compression unit.

In particular, the compression unit is composed of an upper part provided with a coupling hole and a lower part provided with a coupling protrusion, and can be easily mounted and detached by rotation, thereby making it easier to replace the compression unit.

Therefore, it is possible to drastically reduce the manpower and time required according to the change of the acceptance drum.

Second, by configuring a protective sleeve selectively fitted to the inner peripheral surface of the packaging drum, there is an advantage to effectively prevent deformation or damage of the packaging drum during the compression process of the receiving drum.

In addition, the protective sleeve is fitted to the inner circumferential surface of the packaging drum automatically in the compression process by the sleeve drive unit, thereby to perform the compression more smoothly.
