摘要:
The invention relates to a centrifuge, in particular a separator, comprising an inlet tube (3) and a distributor (5) for introduction of a material to be spun into a spinning chamber (9), defined by a spinning drum (7), within which chamber a sieve is arranged essentially coaxial to the inlet tube (3) and/or sieve. The distributor is arranged in such a way that the material to be spun is fed to a region of the spinning chamber, arranged radially external to the outer circumference of the sieve - solid collection chamber such that during a separating spin, a liquid component of the fed material to be spun flows radially from the outside to the inside through the sieve (11), whereby the solid collection chamber may be discontinuously closed. On opening the solid collecting chamber (13) to remove the solids, contaminants on the sieve are removed by back-flowing liquid and the sieve is thus cleaned.

Rotor for a centrifugal separator, which rotor (1) during operation rotates in a space (4) and inside itself forms a chamber (12) and a passage (7), which extends radially outwardly from the chamber (12) to the outside of the rotor (1). In order to accomplish at low costs such a rotor (1), in which gas present in the chamber (12) and in the passage (7) does not generate sound, the passage (7) in the rotor is designed with a radially outer portion (13), which extends radially inwardly from the outside of the rotor (1), and which has a cross section perpendicular to the central axis of the passage (7), which in a plane perpendicular to the rotation axis through the central axis has an extension, which continuously decreases by the distance from the outside of the rotor (1) to a radially inner cross section, which has a certain extension in this plane and from the outside of the rotor (1) is located at a distance along the central axis, which at least is one third of the extension of the radially inner cross section in said plane, and that the extension of the cross section of the passage (7) at the outside of the rotor (1) in the plane is between four and nine thirds of the extension of the radially inner cross section in said plane.
摘要:
A separator (222) for separating a first fluid of less density from a second fluid of greater density through rotation about an axis of rotation (292). The separator includes a separator chamber (350) mounted for rotation about the axis of rotation. A first weir (380) is positioned in fluid communication with the separation chamber. A second weir (400) is positioned over which the second fluid may pass to exit the separation chamber through a collection chamber (488). A fluid pressure chamber is positioned radially outwardly from the crest of the second weir to receive the second fluid as it passes over the second weir. The fluid pressure chamber is partially defined by an exit weir over which the second fluid may pass. A gas chamber (440) is postionned in the passageway between the second weir and the exit weir and includes a gas escape passageway.

A centrifugal separator (1) having a stationary casing (2) and a centrifuge rotor (3), which is provided in the stationary casing (2) and arranged to rotate around an axis (x) of rotation at a rotary speed and which comprises a plurality of nozzles (7) for discharge of a product from the centrifuge rotor (3). The centrifugal separator comprises a sensor device which comprises a transfer element (21), which has a first part (21') and a second part (21") and which is configured to be mounted in such a way that the first part (21') is located inside the stationary casing (2) and outside the centrifuge rotor (3) and that the second part (21") is located outside the stationary casing (2). At least the first part (21') of the transfer element (21) has an elongated shape, a receiving head (23), which is comprised by the first part (21') of the transfer element (21). The sensor device further comprises a sensor element (30), which is mounted to the second part (21") of transfer element (21) and which is configured to sense vibrations and/or shock pulses propagating from the receiving head (23) to the sensor element (30), and an evaluation unit (31), which communicates with the sensor element (30) for transmitting signals from the sensor element (30) to the evaluation unit (31). The transfer element (21) is mounted in the stationary casing (2), directed such that the end face of the receiving head (23) faces the passing jets from the nozzles (7) during rotation of the rotor. The invention also refers to a centrifugal separator (1) with such a sensor device.

摘要:
A centrifuge bowl for separating heavier particles from lighter particles and water comprises a first conical bowl wall leading to a pair of annular recesses at actually spaced positions. Each recess is generally V-shaped with an upper side wall, a lower side wall and a base. The base contains a plurality of angularly spaced discharge ducts each having a pinch valve by which it can be closed and mouth projecting through the base into the interior of the bowl for collecting the heavier particles. Each recess includes injection openings in the upper and lower side walls of the recess arranged to inject fluidizing water in a direction generally parallel to the base and across the mouth of each discharge duct. An insert member formed by two annular screens can be inserted into the recess radially inwardly of the discharge and injection holes and contains a bed of beads which act to float inwardly while the valves are closed and to collapse outwardly when the valves are opened.
摘要:
A centrifuge with controlled discharge of dense materials disclosed. A centrifuge includes a fluid separation wall placed within a sleeve to form a containment zone therebetween. The fluid separation wall aligns and rotates parallel to an axis of rotation. A receptacle forming a part of the fluid separation wall includes a void area. An opening extending through the fluid separation wall from the void area to the outer surface of the receptacle transports the more dense material to the containment zone. A valve ring forming a part of the fluid separation wall includes a valve orifice. The valve ring aligned perpendicular to the axis of rotation and slides along the fluid separation wall to move between open and closed positions. The valve orifice aligns with the opening such that the more dense material exits the fluid separation wall and moves into the containment zone.
摘要:
Prior continuous discharge centrifugal concentrators for separating higher density particles from a slurry have used pinch valves to control the flow of discharge. Such pinch valves tend to be blocked by coarse particles, requiring shutdown of the machine. The present invention provides a muscle-type valve to provide a circular orifice for the valve bore of continuously variable perimeter.
