In general, PCBs (Poly Chlorinated Biphenyls) are chlorine-based organic compounds contained in insulating oil mainly used in electrical equipment such as transformers and capacitors. In addition to the insulating oil of transformers and capacitors, it is an organic chemical that has been widely used worldwide for paper, plasticizers, paints, and the like.

In particular, since all the electric devices generate high heat during use, they have been used as insulating oils and lubricating oils in order to suppress the generation of such heat, but now they are mainly used in transformers, column transformers, rectifiers, and the like of railway vehicles.

When the rod of the dryer cover detachable cylinder 130 is advanced (downward in FIG. 2A) and the connection fixing tool 131 is coupled to the connector, the connection fixing tool 131 is coupled to the connector. Here, the coupling method of the connection fixture 131 and the connector can be directly coupled by the operator using a coupling means such as bolts and nuts, according to the needs of those skilled in the art to configure the connection fixture 131 in the form of a chuck, It can be configured to be self-coupled by supplying power.

When the coupling fixture 131 and the connector is coupled as described above, by moving the washing machine cover (Ab) to the upper left as shown in Figure 2b in reverse to the above process, using a overhead crane (C), such as a transformer ( Place T) inside the dryer body (Aa).

In this case, as shown in FIG. 2C, the transformer T is seated on the transformer fixing chuck 310 of the transformer turning part 300, and the seated transformer T is fixed by the jaws 311.

Here, it is natural to dismantle the coupling means such as bolts and nuts for coupling the transformer (T) and the transformer cover (Tc), so that the subsequent process is smooth.

When the transformer T is fixed to the transformer turning part 300 as described above, by operating the washing machine cover detachable part 100 to combine the washing machine cover (Ab) and the washing machine body (Ab), the washing machine cover Detachable portion 100 is removed from the dryer cover Ab to the original position.

When the washing machine (A) is sealed by the above process, by operating the transformer cover detachment cylinder 210 of the transformer cover detachment unit 200 so that the electromagnet 230 is in close contact with the transformer cover (Tc), The electric current is supplied to the electromagnet 230.

Here, in order to ensure that the electromagnet 230 is in close contact with the transformer cover (Tc), as shown in Figure 3a, the guide sphere 221 and the guide sphere 221 is provided and fixed to the dryer cover (Ab) and It may have a guide rod 222 coupled to the slide movable.

Thereafter, when the rod of the transformer cover removal cylinder 210 is retracted (upward in FIG. 3B), the transformer cover Tc is separated from the transformer T.

Then, when the washing machine tilting cylinder 400 of the washing machine tilting unit 400 is operated to advance the rod (upward direction in FIG. 4), the washing machine is rotated while the tilting shaft connector 420 and the tilting shaft 430 rotate. (A) is rotated and the insulating oil inside the transformer (T) flows into the dryer (A) as shown in FIG.

After a predetermined time has elapsed, when the washing machine tilting cylinder 410 is retracted, the washing machine A is returned to its original position, and the insulating oil is collected at the lower part of the washing machine A.

On the other hand, while the above process is in progress, the cleaning solution supply unit 500 maintains the state as shown on the left side of Figure 5, when the insulating oil is collected in the lower part of the washing machine (A) and the washing machine (A) in its original position, As shown in FIG. 5, the supply cleaning liquid transfer pipe 520 and the supply cleaning liquid discharge pipe 530 are sequentially rotated, and are changed to the state shown on the right side of FIG. 5.

At this time, the rotation method of the supply cleaning liquid delivery pipe 520 and the supply cleaning liquid discharge pipe 530 may be variously applied according to the needs of those skilled in the art. For example, a connector (not shown) provided between the supply cleaning liquid inlet pipe 510 and the supply cleaning liquid delivery pipe 520, and between the supply cleaning liquid delivery pipe 520 and the supply cleaning liquid discharge pipe 530. ) Is composed of a ball bearing and the like, and a motor or the like is provided inside or outside thereof to control each tube to be rotated by the control of an electrical signal.

As shown in FIG. 6A, when the end of the supply cleaning solution discharge pipe 530 is positioned above the transformer T, the cleaning solution is supplied through the supply cleaning solution inlet pipe 510 as described above. It will be filled inside.

At this time, the insulating oil collected in the lower part of the washing machine (A) is transferred to a separate storage tank (not shown) through the discharge pipe (H1).

Then, when sufficient washing water is supplied into the transformer T, the washing liquid supplying unit 500 operates in the reverse order of the above procedure to return to the original position.

When the cleaning liquid is filled in the transformer T, as shown in FIG. 6B, the vibrator 600 is operated to remove insulating oil existing between internal parts such as solid matter.

To this end, when the rod of the connecting arm pivoting cylinder 610 of the vibrator unit 600 is advanced (upward in FIG. 6B), the pinion 622 is rotated by the rack 621 provided at the end of the rod. One side of the bevel gear 630 connected to the pinion 622 rotates, while the other side of the bevel gear 630 rotates, the oscillator elevating cylinder 640 and the connecting arm 650 rotates.

When the vibrator 660 is positioned above the transformer T by the above-described rotation operation, the connecting arm 650 and the vibrator 660 while the rod of the vibrator elevating cylinder 640 retreats (downward in FIG. 6B). ) Moves downward and stops the operation of the vibrator lifting cylinder 640 when the vibrator 660 is contained in the wash water.

When the process is completed, the vibrator 600 is operated in the reverse order of the operation to the original position.

On the other hand, in order to remove all the insulating oil which exists in the transformer T, it is also necessary to remove the insulating oil which exists in the heat sink Th.

To this end, by operating the cutting hole lifting cylinder 710 of the heat sink cut portion 700 to move the rod of the cutting hole lifting cylinder 710 forward (downward in Figure 6c), the cutting provided at the end of the rod As the sphere 720 descends, a portion of the end portion of the heat sink Th is cut by the cutter 721 inside the cutting hole 720.

On the other hand, the transformer (T) is provided with a plurality of heat sinks (Th) according to the type, in order to cut all of the plurality of heat sinks (Th), as shown in Figure 6c to operate the transformer turning unit 300 While rotating the transformer T, all the heat sinks Th provided in the transformer T are cut | disconnected.

Therefore, the air existing in the heat sink (Th) is discharged to the outside through the cut as described above, the cleaning liquid inside the transformer (T) is introduced to the inside of the heat sink (Th) to clean the inside of the heat sink (Th). .

In the state where the heat sink Th is cut as described above, as shown in FIG. 6D, when the washing machine tilting unit 400 is operated to tilt the washing machine A, the washing liquid inside the transformer T is washed with the washing machine ( A) to be flowed into the inside, and the washing machine tilting unit 400 to the original position, and discharges the cleaning liquid through the discharge pipe (H1).

The cleaning liquid discharged as described above is separated from the insulating oil mixed through the centrifuge and then stored in the cleaning tank for reuse.

Subsequently, in the same manner as the cleaning solution supply unit 500 illustrated in FIG. 5, the cleaning solution inlet pipe 810 and the cleaning solution delivery pipe 820 for injection of the cleaning solution injection unit 800 are rotated, and the injection nozzle connector 830 is rotated. Spray the cleaning liquid (for example, the injection pressure is 7KG / cm ² ) through the cleaning liquid injection nozzle 840 provided at the end of the filter) to clean the transformer T and the transformer cover Tc as shown in FIG. 6E. do.

In this case, when the amount of the cleaning solution is sprayed, when the drier tilting unit 400 is operated, the transformer cover Tc is immersed in the contaminated cleaning solution, and is sprayed through the cleaning solution injection nozzle 84. As shown in FIG. 6F, the cleaning liquid sprays only the maximum amount such that the transformer cover Tc is not immersed in the dirty cleaning liquid even after the operation of the drier tilting unit 400.

Subsequently, as shown in FIG. 7, when the contaminated cleaning liquid is discharged through the discharge pipe H1, the blower 910 and the heater 920 of the hot air drying unit 900 may be operated to clean the hot air supply pipe through H2. Hot air is injected into the dry period A.

The high-temperature air supplied as described above dries the solid matter inside the transformer T, and the oil vapor generated during the drying process (steam of insulating oil) is vacuumed by the vacuum pump 930 and the air filter 940. After being discharged to the pump connection pipe H3, it is condensed and removed, and only clean air is discharged to the atmosphere.

Here, the operations of the cleaning liquid spraying unit 800 and the hot air drying unit 900 may be repeated many times as required by those skilled in the art.

When the cleaning and drying of the transformer T is completed as described above, as shown in FIG. 8A, the transformer cover detachment cylinder 210 of the transformer cover detachment unit 200 is operated to operate the transformer cover detachment cylinder 210. ) Advances the rod (downward in FIG. 8A), and when the transformer cover Tc is placed on top of the transformer T, cuts off the power supply to the electromagnet 230.

Then, as shown in FIG. 8B, after opening the washing machine cover Ab by using the washing machine cover detachable part 100, the transformer T and the transformer cover Tc are fixed by coupling means such as bolts and nuts. As shown in FIG. 8C, the transformer T is removed from the dryer A and stored using the crane C. As shown in FIG.

Therefore, by treating the PCBs from the transformer (T) using the hermetic waste transformer cleaning and drying apparatus according to the present invention, it is possible to prevent contamination by insulating oil and oil vapor in advance.

In particular, the operation of each of the above-described configuration is preferably configured to be automatically controlled according to a preset program, it is natural that the program to which various methods are applied can be set according to the type of transformer (T) to be processed and the needs of those skilled in the art. .
