摘要:
Systems and methods for separating fluids from drill cuttings. Specifically, the invention relates to shakers that incorporate a vacuum system and methods of operating such systems to effect a high degree of fluid separation. The system and methods are effective across a variety of screen sizes, vacuum flows and vacuum designs.

A system for dewatering a stream of slurry has a first and a second separator. The first separator removes objects above a first size, to produce a stream of primary treated slurry. The second separator removes objects above a second size from the primary treated stream, the second size being smaller than the first size. Optionally, a third separator removes objects above a yet smaller third size from the stream of secondary treated slurry. The first separator has a plurality of sieve mat supports alternately connected to a main support frame section and a movable support frame section so that the flexible sieve mat can be agitated by the movable support frame section, a collector being provided for collecting the primary treated slurry passing through the flexible sieve mat. In an optional step, water contained in the separated solids is removed.

A system and method for the treatment of a fluid comprising at least two of the fractions solid particles, liquid and/or gas is described having at least one inlet portion and two or more outlet portions, and being arranged to separate solid particles over a predetermined size from the liquid by at least one screening apparatus and then carrying the fractions out of the system. The system (1) being substantially fluid-tight between the at least one inlet and outlet inlet portions and being provided with at least one underpressure-generating device arranged to provide an underpressure in the system.

A method of removing a filtrate storage bottle from a water bath includes inserting at least two finger underneath a radially protruding lip of a filtrate storage bottle sealing cap and raising the at least two fingers to lift the bottle from the water bath. A side wall portion of the filtrate storage bottle sealing cap is smaller in perimeter than a circle surrounding the radially protruding lip. The cap creates a liquid tight seal with the filtrate storage bottle.

A liquid vacuuming and filtering device may include a container having a sealed interior, a vacuum pump connected to the interior, a two-way valve connected to the interior, a flexible hose connected to the valve, a filter positioned within the interior and connected to the valve and a standpipe positioned within the interior and connected to the valve. The pump may be adjusted to a filling configuration, in which the pump evacuates the container interior to a pressure below ambient, causing fluid to be drawn through the hose, valve, and filter, which collects suspended particulates; or to a discharge configuration, in which the pump pressurizes the interior to a pressure above ambient, wherein the valve is adjusted to allow filtered fluid within the container to flow through the standpipe, valve and out through the hose.
摘要:
A method of collecting medical waste in a waste collection unit using a disposable manifold and filter assembly. The disposable manifold and filter assembly includes a manifold housing with a plurality of inlets, a neck extending from the manifold housing to define an outlet, and a filter basket disposed in the manifold housing. The method includes inserting the neck into the waste collection unit to direct the medical waste passing through the disposable manifold and filter assembly into the waste collection unit. Tubes are connected to the inlets of the manifold housing to provide a path for the medical waste to travel from a target site, e.g., a patient, to the manifold housing. A vacuum is drawn in the waste collection unit to pull the medical waste through the tubes and into the disposable manifold and filter assembly where the medical waste is processed/filtered in a plurality of stages.
摘要:
A filtration funnel with integral prefilter usable for filtering fluids. The integral prefilter is disposed above the final filter which is sealed to the funnel. The prefilter may contain one or more layers of prefilter material, and is sealed to the funnel with one or more seal rings. The funnel may be used with either vacuum or pressure.

A liquid extraction unit for extracting liquid from an aqueous material is described. The unit includes a filter that is configured to allow passage of the liquid and prevent passage of the aqueous material. The unit also includes a first vacuum that is configured to extract air from the extraction unit. The unit further includes a second vacuum that is configured to pull the liquid through the filter. The first vacuum and the second vacuum are located after the filter.
