Patent number: 5320747Abstract: A method and apparatus for removing solid matter from fluid systems which does not require system shutdown and minimizes the loss of system fluids. The invention first isolates the solid matter collection reservoir from the fluid system and then purges the reservoir for external disposal or recovery of the solid matter. The purging sequence is enhanced through the use of a venting system which prevents pressure differential buildup and also prevents the introduction of air into the separation device during the purging sequence. The entire process can be controlled manually or automatically through a control system.Type: GrantFiled: December 21, 1992Date of Patent: June 14, 1994Assignee: Claude Laval Corp.Inventors: Steven D.

Patent number: 4997575Abstract: In a filter centrifuge with a filter medium, a filter cake is formed following the introduction of a suspension. In a first filtration phase the suspension is exposed to centrifugal filtration a first filtration which dewaters by the inertia forces. In a second filtration phase, the cake is subjected to compressed gas filtration using frictional forces generated by a gas flow. In the second filtration phase, gas at atmospheric pressure flows through the filter cake and filter medium and is exhausted from a filtrate collector space. This space is composed of a gas space and a filtrate liquid space. To obtain flow through the solid cake at an increased pressure difference, it is proposed to provide the filter centrifuge in a pressure housing with a superatmospheric pressure controlled by a difference in filtrate liquid levels in the filtrate liquid space and the annular space following the filter. This liquid control prevents the penetration of filtrate liquid into the gas exhaust line.Type: GrantFiled: May 26, 1987Date of Patent: March 5, 1991Assignee: Krauss-Maffei A.G.Inventor: Guenther Hultsch

Patent number: 4626345Abstract: Apparatus for removing suspended particles from water comprises outer and inner concentrically arranged tanks and a carriage arranged on top of the outer tank for movement around the same. Unclarified water is introduced into the inner tank along with flocculating material for combining with the suspended particles in the water, and the mixture passes from the inner to the outer tank. Gaseous bubbles are introduced into the mixture for attaching to the flocculated suspended particles and floating them to the surface of the water in the outer tank, forming a sludge layer thereon. A scoop device mounted on the carriage removes the sludge for discharge from the apparatus. A plurality of filter beds are arranged near the bottom of the outer tank for removing the remaining precipitated flocs to complete the clarification of the water for discharge, and suction apparatus is arranged above the filter beds for cleaning the same.Type: GrantFiled: September 4, 1984Date of Patent: December 2, 1986Assignee: Lenox Institute for Research, Inc.Inventor: Milos Krofta

Patent number: 4594166Abstract: An improved desludging device for basket centrifuges facilitates the automatic withdrawal of hard sludge from the centrifuge. The device includes a sludge discharge tube and a sludge re-slurrying tube, the tubes being connected in a loop, so that fluid exiting the centrifuge through the discharge tube reenters the centrifuge through the re-slurrying tube. The re-slurrying tube terminates in one or more nozzles or slots, pointed in the general direction of the discharge tube. This continual recirculation of fluid causes the hard sludge in the centrifuge to return to the form of a slurry, and the slurry is periodically withdrawn from the centrifuge. The re-slurrying effect may be enhanced by the occasional introduction of some process liquid, or other liquid, into the centrifuge. The sludge discharge tube and re-slurrying tube are mechanically linked, and are programmed to move towards the rim of the centrifuge until substantially all the sludge is removed.Type: GrantFiled: March 25, 1985Date of Patent: June 10, 1986Assignee: William D.

Patent number: 4347134Abstract: A slurry separator utilizes the power inherent in the pressurized slurry from the slurry pump through a reaction nozzle to drive a rotor, with the slurry distributed through the nozzle being distributed over the surface of a conical grid. The rotor structure also drives squeegee-like blades which scrape the solids downward inside the cone readying screen for the next discharge, and then sweeping them down into a cylindrical auger chamber where they are compacted downwardly against an inverted conical floor to further squeeze moisture through the sides of a housing cylinder. The conical floor of the compacting cylinder presses up against the particulates to be compacted with a resistance that is proportional to the speed of the rotor, achieved through the use of a centrifugal governor. This action makes it tolerant to variations in nozzle flow volume (pressure) and converts energy output into optimum separation.Type: GrantFiled: September 3, 1981Date of Patent: August 31, 1982Inventor: Oswald C. Svehaug
