  • 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.

  • Publication number: 20170203306
    Abstract: A separator for the centrifugal processing of a flowable product includes a rotatable drum with a vertical rotation axis. The rotatable drum borders a centrifuge chamber and includes a clarifying arrangement in the drum for clarifying the product to be processed in the centrifugal field. The drum has a separating plane between a drum top part and a drum bottom part. A supply system and the drain system are designed on the drum. The separator also includes a housing in which the drum is arranged, the housing having floor part and a housing shell part connectable to the floor part. A separating plane is likewise designed between the floor part and the housing shell part of the housing. The two separating planes are aligned with each other or there is an offset of less than 250 mm between the two separating planes.

  • Publication number: 20160030953
    Abstract: Disclosed is a centrifuge including a rotatable centrifugal drum and a drive spindle to drive the centrifugal drum. The drive spindle is rotatably mounted via a bearing in a housing supported elastically on a machine framework. Further included is a drive device including a drive motor to rotate the drive spindle and a lubricant system to lubricate the bearing. The lubricant system is configured to deliver lubricant from a lubricant supply tank through a lubricant channel into a region of the bearing. An injection device is arranged downstream of the lubricant-supply tank and is configured to deliver the lubricant into the region of the bearing by dispensing quantities of lubricant in temporally discrete pulses with a limited-time air stream. A method is disclosed of directing lubricant into a region of a bearing of the centrifuge as noted above.

  • Patent number: 8845505
    Abstract: A separator includes a centrifugal drum having a vertical axis of rotation and a feed line for material to be centrifuged. A drive spindle for the centrifugal drum is rotatably mounted on a housing via a bearing, the housing being supported elastically on a machine frame. A drive device includes a motor housing and an electric motor having a stator and an armature which is aligned with the drive spindle. The drive device and the motor housing move with the drive spindle as co-vibrating units during an operation of the separator. The drive device is connected to the machine frame below the bearing at a lower axial end of the bearing via one or more joint elements.
