Abstract
A drum washer has a base, a barrel support structure, and a water delivery system. A hollow drum is turned over and placed on the drum washer by inserting a spray head of the water delivery system through a hole in a top cover of the drum and into the interior of the drum. The barrel support structure holds the drum at a fixed angle while water is sprayed from the spray head onto interior surfaces of the drum. The water rinses the interior surfaces of the drum and drains out the hole in the top cover of the drum.
Claims9
A drum washer for rinsing inside surfaces of a substantially hollow drum, having an interior defined by a side wall, a bottom cover at one end of the side wall and a top cover at another end of the side wall the top cover having first and second holes providing access to an interior of the drum, the drum washer comprising:
- a base structure;
- a drum support structure connected to the base structure and having a configuration to contact the side wall and to support the drum in a rinse position in which the top cover is located below the bottom cover;
- a water delivery system connected to the base structure and operative to deliver water into the interior of the drum, the water delivery system including first and second generally parallel delivery pipes each having a different length and also including first and second spray heads connected to each of the first and second delivery pipes for spraying water from the first and second delivery pipes, respectively, the delivery pipes oriented relative to the drum support structure to project into the first and second holes when the drum is supported on the drum support structure in the rinse position, the first and second delivery pipes oriented to extend substantially parallel with the side wall of the drum when the drum is supported on the drum support structure in the rinse position, respectively, the different lengths of the first and second delivery pipes extending into the interior of the drum, different distances from the top cover when the drum is supported on the drum support structure in the rinse position, and the first and second spray heads spraying water from the first and second delivery pines, respectively, within the interior of the drum at two different distances from the top cover.
