DEVICE FOR COLLECTION OF SLURRY Russian patent published in 1994 - IPC

FIELD: gas and oil industry water-supply equipment. SUBSTANCE: device includes sections of slurry collector installed one above other, supply branch pipe, shut-off valve and discharge duct, counter-siphon valve and unit for intensified collection of slurry. Discharge duct is built in the form of branch pipe installed with lower end in upper part of one section of slurry collector uniaxially to it, is passed through bottom of section of slurry collector positioned above and passes to supply branch pipe of section of slurry collector placed above. Sections of slurry collector are made fast to mentioned branch pipe. Counter-siphon valve is put into side hole made between sections of slurry collector in branch pipe coupling them. Unit for intensified collection of slurry is manufactured in the form of pump element with blades, vortex chamber and inlet and intake circular chambers separated with partition. Intake chamber is isolated from vortex one and communicates with outlet hole of supply branch pipe and with inlet chamber through holes made in partition separating them. Vortex chamber communicates with intake chamber with the aid of longitudinally arranged vertical tangential slots formed with blades of pump element made fast to upper part of section of slurry collector. It has outlet into space of section of slurry collector. EFFECT: enhanced efficiency and reliability of collection of slurry. 2 dwg
