Abstract
The device employs the jet pump principle to bring a power fluid to sedimented solids and the like plugging a conduit, and it includes at least one nozzle which directs the power fluid in a high-velocity jet against the solids to bring the solids into suspension for subsequent removal thereof using the jet pump principle.
Claims26
A device for removing solids from a conduit, which device comprises:
- a jet pump including a pump body, a main nozzle, and at least one cleaning nozzle for bringing a power fluid to said solids;
- passage means in said device for flowing power fluid to said main nozzle and to said at least one cleaning nozzle, whereby said at least one cleaning nozzle directs said power fluid in a high-velocity jet against said solids to bring said solids into suspension for subsequent removal of said solids by said jet pump;
- and
- pressure responsive variable flow valve means responsive to the power fluid pressure and located in said pump body and connected in fluid communication with said at least one cleaning nozzle and said source of power fluid.

A device for removing fluidized solids from a conduit, which device comprises:
- a jet pump, said jet pump including a pump body having walls defining a venturi throat, a main nozzle, and at least one nozzle located in said pump body for directing power fluid against the wall of said venturi throat;
- and
- passage means in said device for flowing power fluid to said jet pump and to said at least one nozzle to produce a liquid film for protection of said venturi throat against the abrasive action of the stream of fluidized solids which is being pumped up to the surface.
