摘要： A screw conveyor (2) intended and formed for use in a decanter centrifuge for separation of solid particles from a fluid compound, comprising a central body (10), at least one conveyor thread (11a; 11b) and at least one baffle (12) bridging a flow path formed between different parts of the conveyor thread. The screw conveyor (2) has at least two originally separate parts (22, 23), each of which comprises a portion of said conveyor thread (11a; 11b) and which are kept together axially. The baffle (12) constitutes a separate member arranged to be kept in place between said parts (22, 23) of the screw conveyor, when these parts are kept together axially, and has a portion (26; 27) which forms a part of the conveyor thread (11a; 11b) in an area where the conveyor thread intersects with and extends past the baffle (12).

摘要： Provided herein are a centrifuge assembly and method for gaining access to an accelerator. A centrifuge accelerator system is releasably mounted within a centrifuge assembly by a detachable connector, thereby providing accessibility to the accelerator. The centrifuge assembly includes a hollow bowl (52), a rotating conveyor (10), a drive shaft (20), and an accelerator (30). A series of detachable connectors (40,41) are used to mount the drive shaft (20) and accelerator (30) within the centrifuge assembly, providing a repeatable technique for gaining access to the accelerator (30) without damaging or destroying the rotating conveyor (10) or drive shaft (20). Mounting the accelerator (30) in a detachable, non-permanent manner renders the ability to repair or replace the accelerator (30) more efficient.

摘要： The invention relates to a solid bowl screw centrifuge comprising a rotating drum (3) having a horizontal rotation axis, which surrounds a centrifuging chamber (11), a rotating screw (5) rotatably mounted inside the drum (3), and at least one liquid discharge and at least one solids discharge. The liquid discharge is effected by a peeling disc (19) downstream from which a blocking chamber (29) is connected. The inventive centrifuge is characterized in that the blocking chamber (29) is a hydrohermetic blocking chamber (29) which serves to seal the centrifuging chamber (11) from the surroundings by using a sealing liquid, to which a feed line (35) is directly assigned for feeding the separate sealing liquid that is independent from the centrifuge material, and in that the screw centrifuge (1) has a second siphon disc (21) that, starting from the screw (5), radially extends outward into the centrifuging chamber (11).

摘要： The decanter centrifuge comprises a screw conveyor having a body (4), which carries a screw comprising one or more flights (7, 7´) and having a nominal transport speed varying along the longitudinal axis,. An inlet (6) is provided in the screw conveyor for the material to be separated. The screw conveyor is provided with a baffle (8, 8´) dividing the separation chamber in a substantially cylindrical separation part (17) and an at least partially conical discharge part (18). Immediately upstream of the baffle (8, 8´) a transition part (19) is provided between the separation part (17) and the discharge part (18), the screw conveyor (3) having a bigger nominal transport speed in the transition part (19) than in the separation part (17) immediately before the transition part (19), the change of the nominal transport speed being established by a change (21) of the screw pitch.

摘要： The helical conveyor centrifuge is provided for the wet-mechanical separation of solids mixtures and has a rotor (10), which can rotate about a horizontal axis (24) and is composed of a cylindrical drum (12) and of two conical drums (14, 16). The helical conveyor centrifuge also comprises a screw conveyor (26), which is mounted inside said rotor, rotates about the same axis (24), and has two contra-rotating screws (30, 32). The inventive centrifuge additionally comprises means for axially feeding the solids mixture into the centrifuge and has discharge openings (42, 44), which are situated near the ends of the conical drum walls while being provided for discharging floating material and settled material. A radially inward projecting barrier device (48) for creating a different liquid level (50, 52) for the floating material and the settled material is mounted on the rotor (10).

摘要： In order to create a solid-bow centrifuge for mechanical drainage and thermal drying of sludges, in which the possibility of clumping or of bake-on of the finely dispersed thick matter spun off from the thick matter outlet openings (11) is minimized or prevented, according to the invention it is proposed to provide in the flight path of the spun off thick matter, a baffle cone (14) surrounding the thick matter outlet openings (11) at a distance and which rotates at a high circumferential velocity, that is, preferably it rotates together with the basket shell (10), and whose inner, ring-shaped, rotating conical surface accelerates the arriving thick matter and prevents solids bake-on.

摘要： A decanter type centrifugal separator capable of discharging sludge directly from a portion of the sludge with least moisture content in a bowl so as to lower a moisture content and increase a separation efficiency, wherein a screw conveyor rotated with a difference in speed provided relative to the bowl is stored in the bowl rotated at a high speed, a dewatering cake discharge route (20) is provided in one end wall (2) of the bowl, an opening (20a) of the route into the bowl is provided near the inner peripheral wall of the bowl, the discharge route provides a restriction effect to the discharge of the dewatering cake, and a sedimentary layer with thick sedimentation layer is formed near the opening, whereby that portion only of the cake is discharged through the discharge route under water head of the sedimentation layer, that portion receiving the highest consolidation effect by the water head of a centrifugal force acting on the sediment, among the sedimentation layers accumulated at one end of the bowl.
