ABSTRACT:
This relates to a barrel or drum scraper to facilitate the complete emptying of a barrel or drum. Barrels and drums which are filled with a liquid containing solids and the like frequently have the solids settle out and become deposited on the inner surface of the barrel wall and the barrel bottom. Thus when you pour out the liquid content of a barrel filled with such a product, there remains in the barrel the solids which have adhered to the body and bottom. This relates to a scraper and barrel handler which will effect the removal of the solids from the walls of the barrel. This is particularly true when the barrel is used to store contaminated materials. In one form, the apparatus includes a barrel support which accurately positions the barrel, after which the scraper assembly moves down into the barrel. The scraper assembly includes a cylindrical scraper and a stirrer which is generally in the form of a cookie cutter which first cuts the deposit on the bottom of a barrel into segments and is then rotated so as to loosen all of this sediment. In another form of the apparatus, the barrel is clamped to a barrel support then the barrel is inverted to pour out what will flow out of the barrel, after which the inverted barrel is engaged by the bottom thereof in bottom supporting relation and pushed down over a combined fixed cylindrical scraper and stirrer with there being drive means for the scraper assembly.
