The present invention relates to a cleaning device for a drum, in particular, while washing the exterior of a drum that is continuously transported along a conveyor, tilting and rotating the drum in a horizontal direction and spraying washing water while rolling the tilted and rotated drum to wash the outer circumference of the drum, simultaneously washing the upper and lower surfaces of the drum, spraying air to dry it, and then standing the drum in a vertical direction again, thereby rapidly washing and drying the outside of the drum while preventing the accumulation of washing water due to protrusions. It is possible to firmly support the drum during horizontal tilting rotation and vertical standing rotation of the drum, and a booth-type case is provided in the washing section of the drum to cover the outside of the drum, so that washing water splashes outside during washing of the drum to prevent contamination of the surroundings.

In general, a large amount of chemicals or oil is shipped in a state in which it is packed in a large-capacity drum, and is used by the user.

These drums are not discarded as they are after use, but are collected, cleaned, and reused. In order to collect and reuse the drums after use, they are used in a state in which the drums are cleaned.

That is, various foreign substances such as contents and dust are buried inside the drum that has been used. As described above, when new contents are filled with remaining contents and foreign matters, it is difficult to maintain high purity quality due to contamination of the contents. In addition, due to discoloration of the product, the contents cannot be stored for a long time, and there is economic loss such as having to be disposed of without being able to use it.

In this relationship, the contents of the used contents and various foreign substances are not left inside the drums collected after use, and then washed and reused.

However, since the inside of the drum is cleaned by a worker manually, there is a problem in that there are many difficulties in cleaning.

Recently, in order to solve the above problems, the washing nozzle sprays the washing liquid into the drum in a state where the washing nozzle is raised into the through-hole formed in the drum, so that the inside of the drum can be more easily cleaned. A drum washing device is widely used.

However, there is a problem in that the operator's workability is greatly deteriorated because the operator has to manually adjust the position of the through-hole of the drum and the position of the washing nozzle to match with the naked eye.

As the conventional prior art related to drum washing, as disclosed in Korean Patent Registration Publication No. 10-1133521 "waste drum washing device" (registration date: 2012.03.29), a plurality of waste drums to be washed are horizontally rotatably seated on the upper part sequentially, and the other end rotates up and down while one end is shaft-coupled to one side of a transfer part that sequentially and intermittently transfers a plurality of waste drums from one side to the other direction. In the same way, a horizontal frame for vertically and sequentially seating a plurality of waste drums on an upper portion of one side of the transfer unit, and a vertical frame in contact with one side of the plurality of waste drums formed on one end of the horizontal frame and horizontally rotatably and sequentially seated on the top of the horizontal frame; It is provided on the vertical frame of the frame and is formed at regular intervals on one side of a plurality of waste drums that are seated and rotated horizontally and sequentially on an upper portion of the horizontal frame. Among the first and second through-holes having different sizes, a sensing unit for detecting the one-side through-hole having a larger size than the other through-hole; It is provided inside the horizontal frame of the frame and rotates the plurality of waste drum cylinders according to the output signal of the sensing unit in a state of being in contact with the plurality of waste drum cylinders horizontally and sequentially seated on the upper part of the horizontal frame. A rotating member provided in the transfer unit and adjusting the position of the one side through-hole to match the position of the washing unit for spraying the washing solution into the plurality of waste drum cylinders through the one side through-hole.

In addition, as another prior art related to conventional drum cleaning, as disclosed in Korean Patent Publication No. 10-1258115 "Automatic Cleaning Device" (Registration Date: 2013.04.19), a drum rotation unit that turns the drum upside down so that the inlet of the drum to be washed faces downward, and is installed in connection with the drum rotation unit, while rotating the overturned drum in the drum rotation unit, the rotation of the drum is stopped when the position of the inlet is detected, so that the inlet is placed in a certain position. It is installed in connection with the positioning unit and the drum positioning unit, and is installed in connection with the drum washing unit and drum washing unit that receives the drum with the inlet position uniformly arranged from the drum positioning unit and inserts a nozzle that sprays cleaning liquid into the inlet to clean the inside of the drum. It includes a drum moving unit that moves the drum so that the drum is transferred from the adjusting unit and the drum position adjusting unit to the drum cleaning unit.

However, in the conventional drum washing, the drum is laid horizontally to clean the inside of the drum filled with chemicals and the like, and the washing liquid is sprayed into the drum.

Referring to FIG. 1, the upper surface 12 and the lower surface 14 of the existing drum 10 have protrusions 15 protruding more than the upper surface 12 and lower surface 14 to supplement strength and prevent contamination of the stopper 16 at the edge of the upper surface 12 and lower surface 14.
