  • Patent number: 11020754
    Abstract: An outlet nozzle for centrifugal drums has a nozzle body with at least one cylindrical portion and having an insert connected to the nozzle body. An inlet channel and an outlet channel, which is oriented at an angle with respect to the inlet channel, are formed in the nozzle body. The insert has a torque transmitting contour for arranging a tool with a complementary tool torque transmitting contour in position in order to rotatingly secure the nozzle body in an opening of a rotatable centrifugal drum and to release said nozzle body. The insert also has a polygonal cross-section, which is smaller than the cross-section of the cylindrical section. The insert starting from the polygonal, in particular, rectangular cross-section, merges with the cylindrical section of the nozzle body over rounded surfaces having a radius greater than 1.0 mm.

  • Patent number: 10987633
    Abstract: A filtration arrangement for a filtration device having a container. The filtration arrangement includes at least two or more hollow shafts, rotatably mounted in a machine frame, on which a plurality of membrane filter disks are arranged. At least one drive device is allocated to the plurality of hollow shafts. Permeate can be discharged from the container through the hollow shafts. Each hollow shaft can be inserted into the container on one of the ends thereof having the plurality of membrane filter disks, such that the opposite end thereof protrudes out of the container. Several or many of the membrane filter disks are arranged axially spaced apart on each hollow shaft, and deformable spacer sleeves are arranged between one part or all adjacent membrane filter disks and axially space apart the membrane filter disks on the hollow shafts.

  • Patent number: 10894259
    Abstract: A separator with a rotating system includes a drum with a vertical axis of rotation, which drum is rotatable during operation, and a drum inner chamber subdivided into a lower double-conical centrifuging chamber and an upper double-conical centrifuging chamber. Both centrifuging chambers have solids discharge openings that are openable and closable in the lower centrifuging chamber by a piston slide and in the upper centrifuging chamber by an auxiliary slide. The mass moment of inertia JQ of the rotating system about a transverse axis Q extending through the center of gravity S of the rotating system of the drum and which is perpendicular to the vertical axis of rotation D is greater than the mass moment of inertia JD of the rotating system about the vertical axis of rotation D of the rotating system.

  • Patent number: 10882058
    Abstract: A solid-jacket screw centrifuge is disclosed. The centrifuge has a rotatable drum with a horizontal axis of rotation which encloses a bowl with a rotatable screw, an inlet for introducing material to be centrifuged into the bowl, at least one liquid and at least one solid discharge, where at least the solid discharge is assigned a non-rotatable housing surrounding it, at least radially bounding a discharge chamber, where the discharge chamber is designed as a drying chamber for the solid matter and has axial walls and one or more walls in the radial direction. The housing extends axially parallel to the axis of rotation at most into the conical region of the drum or the screw.

  • Patent number: 10865880
    Abstract: A seal arrangement for a process device or installation. A component arrangement has two components adjoining one another in sections in the area of a gap. A groove toward the gap is formed on one of the two components, which groove is L-shaped and is open toward an edge of the gap. A seal is inserted into the groove, which seal also has an L shape that corresponds to the L shape of the groove, for which purpose the seal has a first sealing limb and a second sealing limb at right angle thereto. The first sealing limb is designed so that the first sealing limb is inserted into the first limb of the groove, and the second sealing limb is designed in such a way that the second sealing limb can be inserted into the second limb of the groove and is firmly clamped there, and the first sealing limb is firmly clamped into the first limb of the groove in the manner of a sealing foot with oversize.

  • Patent number: 10744518
    Abstract: A method for monitoring a screw centrifuge, such as a solid-bowl or a screen-type screw centrifuge. The screw centrifuge processes a product so that solids conveyed out of the drum with the screw are removed from the product. A current angular speed and an average angular speed of the transmission input shaft for the screw over time are determined. The current and average angular speeds are evaluated and a warning signal and/or changing one or more operating parameters of the screw centrifuge is changed if dynamic changes in the angular speed are detected during the evaluation.
