[0001] DRUM CLEANING APPARATUS AND CLEANING METHOD [0002]

The present invention relates to a drum cleaning apparatus and a cleaning method using the same, and more particularly, to a drum cleaning apparatus and a drum cleaning apparatus using the same, And a cleaning liquid sucking unit for sucking and discharging the cleaning liquid from the other direction, and a cleaning method using the same.

In general, a drum is a storage tool used to store a liquid material such as a large amount of paint or oil in the inside, and to prevent deterioration of a liquid material and to safely store the liquid material when it is taken out little by little at every use period. Only a small access hole is formed on one side of the drum to minimize contact with foreign matter.

In order to recycle the internal liquid material after all the internal liquid materials have been used, the inside and the outside of the drum are recycled by being cleaned. When new contents are stored without being cleaned, a new liquid material and dust The liquid material can not be stored for a long period of time due to the deterioration of the liquid material, and it is economically disadvantageous in that it can not be used for a long period of time.

However, as a conventional method of washing the inside of the drum, only a manual washing operation is performed by a worker. Therefore, there is a lot of difficulty in washing work, and the number of drums to be cleaned is smaller than the time required for the operation, There was a problem of falling very much.
