The air separator has at least one immersion tube which abuts the conical wall of the conical hollow body and which protrudes upwards within the conical hollow body, the conical hollow body tapered tip which faces downwards being connected to an outlet for fine material. The first cylindrical hollow body is equipped with a rotating rod basket which is enclosed by a static circular conveyor trough for coarse material, the conveyor trough resting against the lower outer circumference without contacting same. The conveyor trough for coarse material is connected to an outlet out of the cylindrical hollow body, and the volume enclosed by the rod basket is fluidically connected to the conical hollow body.

Systems and methods for removing contaminants from surfaces of a solid material using a flow of compressible fluid to draw incompressible fluid through pathways between fragments of the solid material. At least one method includes introducing solid material into a processing chamber, concurrently directing compressible fluid and incompressible fluid into the processing chamber via the inlet fluid distribution manifold, and operating a vacuum pump to maintain a pressure at a discharge outlet of the processing chamber sufficient to promote the compressible and incompressible fluids each achieving a velocity of at least 10 meters per second within the processing chamber.

A fuel pick-up device (10) for a fuel tank (13) has a head (11) for fitting to a wall of the tank (13), and an elongate body (14) which extends from the head (11) into the tank (13). A water separator disposed in body comprises an axially-extending separation chamber (18), and a vane (21) for creating a helical flow of fuel flowing through the chamber between an inlet (17) and an outlet (23), wherein any water in the fuel entering the separation chamber through the inlet (17) moves radially outwardly in the helical flow away from the outlet (23), the outlet (23) being arranged such that fuel drawn from the chamber (18) is substantially free of water. Water separated from the fuel is collected in a chamber (25) and can be removed via a drain (24).

Dust separation devices are disclosed to enable separating and collecting dust particles. The devices include a vacuum port and a cyclone chamber that are connected by a tube between the vacuum port and an upper end of the cyclone chamber. On the cyclone chamber there is an input port for connecting to a hose for ingesting the dust particles. The devices also include a dust receptacle having a top upper surface and a port cover on a port formed in the upper surface for emptying the receptacle of collected dust particles and a lower portion of the dust receptacle that is integrally formed into the upper surface of the dust receptacle.

A surface cleaning apparatus such as an extractor has a liquid delivery system comprising at least one spray nozzle that delivers at least one liquid and an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a lower end, a lower end wall, an upper end and an upper end wall, the lower end having a cyclone fluid inlet and a cyclone air outlet and the upper end has a separated element outlet, wherein the cyclone air outlet comprises a treated air outlet conduit and a liquid blocking collar is provided on an outer surface of the treated air outlet conduit below an inlet to the treated fluid outlet conduit. A solid and liquid collection chamber is in communication with the separated element outlet.

A forward secant swirl tube may be used to separate heavier particles such as oil and moisture from an air flow. The swirl tube includes a central hub having a centerline and a circular perimeter. An outer circular housing extends from an inlet edge to an outlet edge. A plurality of vanes extends from the central hub to the outer housing. The vanes are equally spaced around the central hub. Each vane has an inlet transition portion connected to a discharge portion. The top edge of the inlet transition portion of each vane is offset from the centerline of the central hub forming a forward secant line with respect to the centerline of the central hub and a direction of spin induced by the plurality of vanes.

A multi-cyclonic dust filter device comprises a dust collection chamber for collecting dust, a cyclonic chamber providing a gas to-be-filtered out dust to enter and forming a first cyclone to enter into the dust collection chamber, and a deflector component disposed between the dust collection chamber and the cyclonic chamber; the deflector component comprises a first deflector tube for receiving the gas to-be-filtered out dust refluxed from the dust collection chamber and forming a second cyclone, and a second deflector tube disposed in a same axial direction as the first deflector tube and separately disposed by an airflow convergence interval, the first deflector tube is provided with at least one dust filter hole for discharging the dust in the second cyclone, and the second deflector tube combines the first cyclone and the second cyclone through the airflow convergence interval to form a third cyclone for discharging.

The invention concerns a method and an apparatus for operating a multi-phase pump which has a suction-side inlet (10) and a discharge-side outlet (20) and which pumps a multi-phase mixture charged with solids, comprising the following steps: a. pumping a multi-phase mixture into a discharge-side separation chamber (45), b. separating a gaseous phase from a liquid phase and a solid phase in the separation chamber (45), c. separating the liquid phase from the solid phase in the separation chamber (45), and d. supplying a portion of the liquid phase freed from the solid phase to the suction side.

Liquid separator provided with a housing which includes an at least partially cylindrical wall defining a separation chamber, closed at one end by a base and at the other end by a lid in which there is a gas outlet for the discharge of the treated gas. A shield is provided in the separation chamber surrounding the gas outlet in the separation chamber from the aforementioned lid. The liquid separator has an inlet for a liquid-gas mixture to be treated. The inlet is located in the lid so that the liquid-gas mixture tangentially enters the separation chamber in the space between the wall and the shield.

A turbine engine having an inducer assembly. The inducer assembly includes a centrifugal separator fluidly coupled to an inducer with an inducer inlet and an inducer outlet. The centrifugal separator includes a body, an angular velocity increaser to form a concentrated-particle stream and a reduced-particle stream, a flow splitter, and an exit conduit fluidly coupled to the body to receive the reduced-particle stream and define a separator outlet.
