Противоточный центробежный экстрактор

A continuous, completely jacketed countercurrent centrifugal extractor of the type utilized to mix and separate two liquids that have different specific gravities and enter through separate inlets. The extractor has at least one overflow weir in a mixing zone between the inlet for the specifically lighter and the inlet for the specifically heavier liquid phase and a division of the mixing zone into mixing-and-separation compartments. Access channels empty into the vicinity of the inner surface of a drum jacket and into that of the heavier phase, to conduct the lighter phase out of the compartment inside the hub of a conveyor worm into the initial mixing-and-separation compartment. One or more overflow channels also empty into the vicinity of the heavier phase, in the overflow weir to divert the lighter phase separated in the initial mixing-and-separation compartment into another and subsequent mixing-and-separation compartment. The design creates several highly efficient contact points in the vicinity of the mixing zone that enhance the extracting action.

Centrifuge, centrifuge adapter, conveyor and method of separating material

Centrifugal liquid separation machine using pressurized air to promote solids transport

A screw type centrifugal liquid separation machine having a continuous decanter and using pressurized air to promote solids transport is provided. The machine has an outer bowl and a conveyor, which are coaxial. A back drive assembly is provided to maintain a difference in speed between the bowl and conveyor so that the conveyor has a mechanical sweeping action within a separation region of the machine. Air is introduced into the machine through the back drive assembly, and is injected into the heavy phase discharge path. In one location, the air acts as a turbulence inducer that at least partially re-suspends grits within the heavy phase material. The air is also injected through lift injectors radially spaced about the solids baffle to provide a uniform solid phase driving force. A flow control is also provided for controlling the discharge rate of the heavy phase material through a discharge port.

Decanter centrifuge

The invention relates to a decanter centrifuge with a rotating bowl (1) provided with at least one solids discharge port (11) and at least one clarified liquid discharge port (15) and a screw conveyor (2) disposed coaxially within said rotating bowl rotated in the same direction with a differential rotational speed, where a feed suspension to be separated is introduced into a ring shaped space formed between said rotating bowl (1) and said screw conveyor (2) through a central feed pipe fixed to the end of the screw conveyor and supported in at least one bearing and can be separated by centrifugal force into a solid and a liquid phase so that said solid phase is discharged from said solid discharge port and said liquid phase is discharged from said clarified liquid discharging apparatus. According to the present invention it is charakterized by a liquid phase conduit (4) arranged in the hollow shaft of the rotating bowl (1) guiding the liquid phase outside of the bearings (16, 18), a liquid phase discharge valve (14) provided outside the bearing on the side facing away from the bowl (1) and screw (2) and a sealing (6) at the end of the feed pipe (10) surrounded by the liquid phase conduit. So it is possible to pressurise the system and to use the pressure from the feed pump to support the cake transport in the solids transporting part of the bowl, thereby eliminating the need for variable speed conveyor control and equipment.

Improved centrifuge system

IMPROVED CENTRIFUGE SYSTEM

A high speed centrifuge which incorporates an elongate conic rotatable housing (11, 12). The housing is centered around a feed tube (10) which delivers a feed liquid into the housing having heavier particles to enable separation. A multi flite conveyor (25) positioned in the housing scrolls heavier particles along the housing toward the tapered end of the housing. An internal surface in the housing defines a pond subject to centrifugal rotation. The conveyor is adjacent to a stack of closely spaced disks (48) which extend into the pond and have spaces therebetween so that liquid in the pond flows between the disks toward the top of the pond while heavier particles migrate through or between the disks and are centrifugally accumulated outside the disks. The conveyor forces heavier particles for scrolling toward the tapered end of the housing.

DECANTER CENTRIFUGE WITH DOUBLE AXIAL SEALING

A decanter centrifuge with a rotating bowl has one solids discharge port, one clarified liquid discharge port and a screw conveyor. A feed suspension is separated by centrifugal force into a solid phase and a liquid phase so that the solid phase is discharged from the solid discharge port and the liquid phase is discharged from a clarified liquid discharging apparatus. A sealing of the feed pipe and the bowl shaft is provided as adjacent double axial sealing. A liquid phase conduit is arranged in the bowl shaft for guiding the liquid phase outside of the bearings, and a liquid phase valve is provided outside the bearing on the side facing away from the bowl and screw. In this way the liquid phase discharge valve can be varied during operation of the decanter centrifuge by a hand wheel via a transmission or by a motor.

The outer portion of the baffle defines with the bowl a restricted passageway which permits the underflow of separated heavy phase material from the separating zone to the heavy phase discharging zone. Pressurizing means, preferably means for maintaining the inner surface of the separated light phase layer inwardly of the weir surface of the heavy phase discharge port, helps advance the separated heavy phase material through the restricted passageway and toward the port through which heavy phase material is discharged.

The decanter centrifuge (10') further including an annular inflatable element (36, 36') positioned adjacent the bowl hub (22') within the bowl (12). The inflatable element (36, 36') adapted to alter the characteristics of the solids layer discharge by varying the radial position (40) of the discharge of the liquid layer from the bowl (12).

Method for separating of a multi-phase mixture and decanter centrifuge system for carrying out this method

An assembly separates a multi-phase mixture into liquid (54) and dry (52) phases and employs a decanting centrifuge (100) with an annular immersion disc (14). A liquor weir is located on the end-face of the centrifuge drum (20). An Independent claim is also included for a separation process in which after starting the centrifuge drum (20) and setting an initial tank depth, the mixture (50) is introduced into the drum. The liquid and dry phases are drawn off. The tank depth and centrifuge fluid level are regulated by the liquor weir until a pre-determined dry substance concentration is reached. The tank depth is continually compared with a tolerance range. During the process the weir is so positioned that a reaction to feed concentration changes is possible in both directions. As the process progresses, the centrifuge speed is lowered in steps and the weir position adjusted so that the dry phase remains constant.

Solid bowl centrifuge for separating liquid-solid mixtures

Besides a first gate (3) for discharging liquids, a centrifugal drum (1) has a second gate (6) for discharging the separated solids. An overflowing edge (8) provided for the solids is located at at least the same radial distance from the axis of the drum as an overflowing edge (5) for the liquids formed by the first gate (3). The length of the overflowing edge (5) of the first gate (3) and the length of the overflowing edge (8) of the second gate (6) have the same mutual ratio as the volume flows to be deflected over the overflowing edges. Because of the hydraulic pressure reigning in the centrifugal drum, the product streams flowing out of the centrifugal drum are subdivided, so that the desired concentration is obtained at the solid side. If the inflowing amount fluctuates, changing the level of liquid in the centrifugal drum, this change has a proportional effect at both gates (3 and 6), i.e. the ratio between the solid concentrate and the separated liquid does not change, so that the solid concentration also remains constant.
