[ The inner peripheral surface of the hole 2a is formed with a female screw so that the cleaning cap 4 is fitted. The cleaning cap 4 passes wash water S and prevents the passage of foreign matter. Specifically, when the drum 2 is inserted into the washing water tank 20 and the washing process is performed, a sticker or other foreign substance adhered to the outside of the drum 2 is dropped through the hole 2a of the drum 2 There is a problem that it flows into the drum 2 and the foreign matter can be prevented from flowing through the cleaning cap 4 having a filtering net.

The cleaning cap 4 includes a lower surface portion 73 formed with a filtering net, a side surface portion 72 extending from the lower surface portion 73 and formed into a coil spring shape and a handle portion 71 formed at the upper end of the side surface portion 72 ). The side portion 72 has a coil spring shape in which an iron rod or iron is rolled in a spiral shape. The outer diameter of the side surface portion 72 may be gradually decreased toward the downward direction toward the hole. That is, the upper end outer diameter D1 of the side surface portion 72 is formed to be equal to or larger than the female thread diameter D3 of the hole 2a, and the lower end outer diameter D1 of the side surface portion 72 is formed to be larger than the female threaded diameter (D3). The outer diameter D1 of the side surface portion 72 is formed larger than the female screw inner diameter D4 of the hole 2a so that the side surface portion 72 can be caught by the thread of the hole 2a. The outer diameter D2 of the lower surface portion 73 is formed to be smaller than the female thread diameter D3 of the hole 2a of the drum 2. [

6, when the user inserts the cleaning cap 4 into the hole 2a of the drum 2, the user first inserts the bottom portion 73 into the hole 2a of the drum 2, , The side surface portion 72 is stretched in the longitudinal direction when the portion 73 is pressed. When the side portion 72 is extended in the longitudinal direction, the outer diameter of the side portion 72 is reduced, so that the side portion 72 can be inserted into the thread of the hole 2a of the drum 2. [ At this time, the first spiral portion 72a constituting the upper end of the side portion 72 is caught by the uppermost thread 2b among the threads of the hole 2a. The second helical portion 72b located below the first helical portion 72a at the side portion 72 is caught by the lowermost thread 2c among the threads of the hole 2a. Therefore, the cleaning cap 4 can be fastened so as not to be detached from the hole 2a of the drum 2. [ Thereafter, when the user pulls the handle 71 after the cleaning is completed, the side portion 72 is extended in the longitudinal direction, and the diameter of the side portion 72 may be reduced and removed from the hole 2a.

The cleaning device 10 of the waste drum further includes a washing water discharge pipe 81, a washing water separation tank 80, an upper foreign matter discharge pipe 83, a lower foreign matter discharge pipe 84 and a washing water circulation pipe 82.

The washing water discharge pipe 81 connects the washing water tank 20 and the washing water separation tank 80 to discharge the washing water in the washing water tank 20 to the washing water separation tank 80. The washing water discharge pipe 81 is provided with a pump (not shown) for pumping washing water from the washing water tank 20.

The wash water separation tank 80 is a tank in which the wash water discharged through the wash water discharge pipe 81 is temporarily stored. The washing water separation tank 80 is formed long in the vertical direction so that the foreign substances of the washing water are separated according to the specific gravity. Foreign matters such as oil discharged from the drum 2 are floating or present on the upper portion of the washing water separation tank 80. Foreign matter having a high specific gravity discharged from the drum 2 is submerged in the lower portion of the washing water separation tank 80.

The upper foreign matter discharge pipe 83 is connected to the upper part of the washing water separating tank 80 and discharges foreign matter having a low specific gravity such as oil floating on the upper part of the washing water separating tank 80 to the outside.

The lower foreign matter discharge pipe 84 is connected to the lower portion of the wash water separation tank 80 to discharge foreign matter having a high specific gravity set to the lower portion of the wash water separation tank 80 to the outside.

The washing water circulating pipe 82 is connected to the intermediate portion of the washing water separating tank 80, that is, the position between the upper foreign material discharging pipe 83 and the lower foreign material discharging pipe 84, (20). Therefore, the washing water of the washing water tank 20 can be reused many times.

The cleaning method using the cleaning device of the waste drum configured as described above will be described as follows.

3 and 4, the drum 2 is first laid down on the drum input tray 22. At this time, the hole 2a of the drum 2 is laid down so as to face the drum discharge port 20b. After the cleaning cap 4 is inserted into the hole 2a of the drum 2 placed on the drum loading table 22, the drum 2 is rolled and charged into the washing water tank 20 through the drum inlet 2a (Step S1).

Referring to FIG. 3A, the drum 2 charged into the wash water tank 2 floats in the wash water S without sinking. At this time, the acupuncture piston 31 presses the outer circumferential surface of the drum 2 for a preset time. The washing water S is gradually introduced into the drum 2 through the hole 2a of the drum 2 and the drum 2 is moved into the washing water S as the needle piston 31 pressurizes the drum 2 And is gradually precipitated (step S2).

3B, when the drum 2 is settled into the washing water S, the pressing piston 51 presses the drum 2 and moves it forward. When the pressing piston 51 presses the drum 2 immediately in front of it, the pressurized drum moves forward and pushes the front drum sequentially. Therefore, the drums successively deposited in the wash water tank 20 are moved forward while being pushed in succession. Here, it is preferable that the pressing piston 51 is set to press the drum 2 by a set distance, and the set distance is a length corresponding to the length of the drum 2.

In addition, the rotating shaft 40 rotates the drums 2 settled in the washing water S. Thus, when the drums 2 are rotated, the caustic soda solution in the drum 2 is rubbed against the inner and outer surfaces of the drum 2 (step S3). The high-temperature caustic soda solution is capable of dissolving contaminants in the drum 2, thereby cleaning the inside of the drum 2 more cleanly and simultaneously cleaning the inner and outer surfaces of the drum 2.

Referring to FIG. 3C, the drums 2 are moved forward so that one of the drums 2 is lifted onto the drum lifter 60. When the lifter rotating member (not shown) rotates the drum lifter 60 by about 90 degrees, the drum lifter 60 is rotated and placed in the vertical direction. When the drum lifter 60 is rotated, the drum 2 which has been raised on the drum lifter 60 is raised upside down on the drum discharge stand 26.

When the drum 2 is upside down, the wash water in the drum 2 can be discharged through the cleaning cap 4 of the drum 2 (step S4). The washing water discharged from the washing cap 4 of the drum 2 can be introduced into the washing water tank 20 again through the holes 26a of the drum discharging stand 26. [ Here, the drum 2 from which the washing water has been discharged from the drum discharge stand 26 is conveyed using a conveyor (not shown) and discharged to the outside (step S5).

According to the cleaning device and the cleaning method configured as described above, the cleaning of the inside and the outside of the drum 2 can be performed simultaneously by precipitating and washing the drum 2 in the cleaning water. In addition, since the caustic soda solution is used, the cleaning ability is very excellent, and even when the contaminants are stiffened in the drum 2, it is possible to dissolve and the cleaning performance is greatly improved.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
