Definitions

  • the invention relates to a device with a discontinuous batch centrifuge for separating syrup from Zucker cafellmassen, with a centrifuge housing with a wall and a bottom, with a cylindrical centrifuge drum in the centrifuge housing, with drain openings in the centrifuge housing, with a first receptacle for from the Drainage holes draining syrup, in particular for receiving a green drain, with a second receptacle for draining from the drainage syrup, in particular for receiving a white drain, with a control device, and controllable by the control device valve or Absperran angelen on or in the drain holes or in connecting lines from the drainage holes to the receptacles, to the separation of green drain and white drain.
  • the invention also relates to a method for separating syrup from Zucker spallmassen means of a discontinuously operating centrifuge.
  • Discontinuous or periodic centrifuges are widely used during sugar production. It is about that process step in which a Zucker Schollmasse is thrown off in a rotating centrifuge drum.
  • the centrifuge drum in this case has a cover screen, through which passes the syrup separated from the filling compound and then passes from the bores of the jacket of the centrifuge drum in a centrifuge housing, in which the centrifuge drum is arranged.
  • white effusion passes through the cover sieve, which is substantially more sugary than the green effluent from the first process step.
  • the white effusion occurs when the first spraying of the crystal layer lying on the cover wire with water rinses out the residual syrup and dissolved sugar crystals and pressed by the centrifugal force through the permeable jacket of the centrifuge drum.
  • the white effluent and the sugar substance dissolved by wash water mentioned as the third liquid, can often be reintroduced into the centrifuge drum at the same stage, for example at the next or the second batch process instead of the wash water.
  • DE-PS 95 969 suggests to provide a separator in a centrifuge housing having a plurality of troughs at different altitudes, each with separate drainage openings. The drainage holes should then be completed independently and thus separate and drain the processes of the different nature.
  • Object of the present invention is therefore to provide a proposal for a device with a reasonable quality of the separation with reduced equipment costs is possible.
  • the switch back to the green drain container was then also made at a clearly defined time, namely at the beginning of the treatment of a new centrifuge batch, such as when filling with a new batch of magma.
  • the switching timing is still the one that switches from the discharge of the drain into the green drain receiving tank into a drain of the drain into a white waste holding tank.
  • the parameter used is now a physical value that allows a precise and objective determination of whether the syrup is now white or green.
  • a representative physical value can be used for example, the color of the process or the conductivity of the process.
  • the first derivation of these values according to time can also be an interesting criterion, ie the speed with which the color or brightness or the conductivity of the syrup changes.
  • the values are different for each batch.
  • the quality of the sugar or the amount of sugar and the amount of washing water dispensed and the type of washing water, which in turn can consist of already processed stages of the syrup which in turn can consist of already processed stages of the syrup, other values for brightness, color and electrical conductivity are achieved.
  • this threshold can be around 60% to 85%, in particular around 80%.
  • Such a threshold is low enough, compared to the maximum value of 100%, to be able to completely rule out false tripping in the case of the usual fluctuations in the measured values, and is high enough to trigger in any case and to absolutely define the difference between green drain and white drain to be able to.
  • ICUMSA units International Commission for Uniform Methods of Sugar Analysis
  • the color in the effluent of raw sugar magma is typically less than 25,000 ICUMSA units, also referred to as IU.
  • white sugar 2-magma ie the white effluent
  • the color of the so-called white sugar 1 magma or refined algae is less than 4,000 ICUMSA units.
  • the starting improvement in quality (white waste being regarded as a better quality than green waste) is used as a criterion for switching the derivative of the currently pending process, whereby in comparison the worst quality (ie the green effluent with the highest color value) of the process is used, which usually pending shortly after the start of the Zentrifugenzyklusses.
  • the determination of the physical value of the syrup may be provided at different locations. It is then to be considered for the switchover that between the place where the physical value is determined by, for example, there is placed a sensor, and the place where the switching takes place, so about the place of shut-off or valve assembly, may be a distance that must first be covered by the syrup before he passes this switching device. Of course, this is not a uniform, but a very complex route, but always the same, so that fixed values can be taken here.
  • an arrangement of a sensor would be useful in a device with a discontinuous centrifuge, as is known approximately from DE 197 31 097 C1, in the wall on which the syrup impinges, preferably in the lower region of this wall.
  • the syrup draining down the inside of the wall and going down would then pass the sensor.
  • the physical values, such as the color could be determined, so that a corresponding signal can then be used to determine the control for the further procedure.
  • a measurement in a ring channel would be possible.
  • a method is used, which is characterized in that during the centrifuging process, the green drain is first collected in the annular channel that after filling the ring channel is allowed with the green drain that overflowing green drain runs over the top of the Ringkanalwandung and on the floor enters the centrifuge housing that when changing from green drain to white drain from the centrifuge drum opens the shut-off in the second connection line and the contents of the annular channel flows into the second receptacle so that the annular channel is emptied that the White drain collected in the annular channel and is also performed in the second receptacle, and that the green drain located on the floor is guided into the first receptacle.
  • This embodiment of the invention consciously accepts contamination of the resulting white effluent by a predetermined and well-defined amount of green effluent. This is contrary to the expert, so from the outset so a deliberate deterioration of the trappable products causes.
  • the advantages that can be gained at the same time more than offset this disadvantage, especially as the resulting mixing ratio is precisely predictable.
  • the first occurring green drain is collected first.
  • This green drain fills the annular channel until it has reached its maximum volume, and then overflows the upper edge of its wall.
  • the volume fraction of the green drain exceeding the upper edge then drips or then flows to the bottom of the cylinder housing.
  • at least the shut-off arrangement remains closed, which could allow the drainage of the syrup from the annular channel.
  • the green drain from the bottom of the centrifuge housing can already be removed into a receptacle at this time, but this can also happen at a later date.
  • the shut-off arrangement opens and clears the way from the ring channel to a second receptacle. This means that the greenery that has been going on since Beginning of the centrifugation has already collected in the annular channel, now goes into this second receptacle through the open shut-off and the associated connection line. At this predetermined volume of green drain but then closes the entire white drain, which now passes into the now emptied annular channel and from there flows through the still open shut-off arrangement and also passes into the same second receptacle. As mentioned, a mixture of a predetermined proportion of green effluent and a very large amount of white effluent forms in this second receptacle.
  • first receptacle collects only green drain. After completion of the process, these collected masses can be further processed or reintroduced into the process at a desired location.
  • a very great advantage of this embodiment is that maintenance and cleaning work practically only have to take place outside the centrifuge housing. Movable parts such as the Absperran glovesen can optionally be exchanged for replacement aggregates outside the centrifuge housing at short notice and then cleaned without time pressure or repaired if necessary.
