Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 7.
  • a generic method provides the DE 44 14 602 A1 in which a method for controlling a discontinuous centrifuge is disclosed.
  • the solids discharge is measured by the measurement of the deposition layer thickness without contact by means of a probe. Subsequently, these values can be compared with the removal values of the filling compounds and evaluated by an external process control system.
  • This method has the disadvantage that it can only be realized for certain products, for example for the separation of sugar.
  • This method of measuring changes in current intensity has the disadvantage, in particular with relatively large separators (beverages, milk), that it is influenced to a greater extent by liquids in the control circuit and hood rinse water. As a result, strongly fluctuating values of the current lift were detected despite optimal emptying.
  • the invention is based on the problems starting from the DE 44 14 602 A1 in the task to provide improved monitoring and / or control and simplified handling of the automation of solids discharge in discontinuous separation processes.
  • the monitoring and / or control based on the speed monitoring of the engine shows a significant simplification compared to the DE 44 14 602 A1 because product-independent offers optimized automation of these separation processes.
  • a speed change characterizes a mass that is extracted from the system.
  • the substance components with the higher density for example solid particles, are carried to the outside under the influence of an inertia and removed via a discontinuously closable discharge opening.
  • the measurement of the speed can be done for example by sensors.
  • sensors for example, inductive sensors or photoelectric sensors can be used depending on the upper load limit of the motor.
  • the magnetic sensors may be mentioned here.
  • Claim 2 also describes a preferred method for speed monitoring.
  • Magnetic and optical sensors are generally inexpensive and can be used in large-scale production.
  • An advantageous method is the attachment of magnets to the drum and the measurement of the variable field strength by the relative movement of a permanent magnet.
  • the measurement is only subject to slight fluctuations due to additional parameters (pre-fill water and hood rinse water).
  • This is mainly used for separators of a larger type, such as those used in milk or beverage processing, for use.
  • the emptying takes place by a piston valve, which can be controlled by a control valve by the measuring and control unit.
  • a piston valve which can be controlled by a control valve by the measuring and control unit.
  • FIG. 1 After the example of Fig. 1 the cross section of a Tellerseparators is shown with a drum 1, which rotates in operation about a center of rotation.
  • the speed change as well as the operating speed of the drum is detected by a measuring and control sensor 4, which directly or indirectly the discharge system for discontinuous emptying, consisting of a spool 5 and a discharge opening 3, controls.
  • a separating device 12 is also known, for example in the form of the illustrated plate separator, which is also supplemented by a solids collecting space 13.
  • control valve 6 should be operated by means of a control unit 4, which responds to changing speeds of the drum.
  • the drum 14 of a separator is connected and driven via a spindle 7 by means of a belt drive 8 to a motor 9.
  • the feed 15 of a solid-liquid mixture of substances takes place at the top of the separator, as well as the drain 16 of the liquid phase.
  • the separated solid is carried out via a discharge opening 17 laterally on the drum.
