Disclosed is a quick connect piping arrangement to remove all residual solvents from empty supply drums.

New regulations governing the shipping and handling of empty solvent containers now stipulates that these containers must be completely empty and dry before the owner can sell or dispose of them.

Solvents are normally removed from their shipping drums via a pneumatic drum pump or other pumping arrangement where by a suction or dip tube is inserted into the threaded bung hole. This dip tube does not fully reach the bottom of the container so as not to obstruct to flow of solvent to the pump. When the pump stops pumping solvent due to air
breaking its prime, the operator tilts the drum towards the dip tube in order to remove more of the remaining solvent. This action works until again the air breaks the pumps prime, thereby leaving approximately half a gallon of solvent in the bottom of the drum. This is where a problem arises. The only way the remaining solvent can be removed is by turning the drum up side down and shaking the drum in order to get the remaining solvent out.

This procedure is unacceptable due to the physical problems associated with handling the drums along with the containment and exposure problems of spilling and transferring this small mount of solvent from the container you are pouring it into, to a proper storage container.

A proposed solution follows. A two inch stainless steel tee is threaded on the bottom to accept a standard bung hole. The top portion o...
