Patent ID: 8153001

Claim:
A liquid vacuuming and filtering device comprising: a container having an interior substantially sealed from its ambient environment, said container including a removable lid capable of forming a substantially air-tight seal with a remainder of said container; a pneumatically powered vacuum pump in fluid communication with said container interior, said vacuum pump including adjustment means for changing from a filling configuration, wherein said vacuum pump evacuates said interior to a pressure below ambient, to a discharge configuration, wherein said vacuum pump pressurizes said interior to a pressure above ambient; a hose; a filter bag positioned within said container interior and having an internal cavity sealed from said interior, wherein particulates contained in incoming fluid are collected in said internal cavity; a discharge pipe positioned within said container interior; and a valve connected to said hose, said filter bag and said discharge pipe and being adjustable alternatively to interconnect said hose to said filter bag and to interconnect said hose to said discharge pipe, said valve being adjustable to a filling configuration, wherein said hose is in fluid communication with said filter, and to a discharge configuration, wherein said hose is in fluid communication with said discharge pipe; said device being oriented to a vacuuming and filtering configuration by placing said vacuum pump and said valve in said respective filling configurations, whereby below ambient pressure in said interior causes fluid in contact with said hose to be drawn through said hose, said valve and said filter, such that particulates in said fluid are collected in said filter bag and said fluid collects in said container interior, and to a fluid discharge configuration by placing said vacuum pump and said valve in said respective discharge configurations, whereby above ambient pressure in said interior causes filtered fluid contained in said interior to be forced through said discharge pipe, said valve and out said hose.
