  • 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: 10040076
    Abstract: A method is provided for clarifying a flowable starting product with a separator having a feed and at least one liquid discharge for continuously discharging at least one clarified liquid phase—a clear phase—and with discontinuously openable solid-discharge openings for discontinuously discharging the solid phase. The method involves the steps: a. setting or determining a starting time; b. repeatedly determining at least one actual value of a product-parameter of the clear phase derived from the drum; c. determining the time interval until the product-parameter actual value reaches or exceeds a product-parameter limit value; d. preferably initiating a solid discharge as a result of reaching or exceeding the product-parameter limit value; e. determining and setting an operating time interval by using the determined calibrating time interval, the operating time interval being less than or greater than the ascertained calibrating time interval; and f.

  • Patent number: 10029921
    Abstract: A method for lowering the pressure inside the hood interior of a separator arrangement with a separator with a rotatable drum includes rotating the rotatable drum about a vertical rotation axis. Before processing a product that is to be processed, a liquid is first directed through the drum and the pressure inside the hood interior is lowered, by a device, as a result of rotations of the drum in the manner of a jet pump. After the pressure inside the hood interior has been lowered sufficiently, then the actual processing of the product that is to be processed is performed.
