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.
- the additional connecting line with the additional obturator separately and selectively eject the located in the annular channel, the first collected green drain and supply the rest of the green drain, which is collected as in the first embodiment in the first receptacle.

- Figure 7 is a schematic representation of a section through another
- FIG. 1 schematically shows a vertical section through a device with a centrifuge housing 10.
- the centrifuge housing 10 has a usually cylindrical wall 1 1 and a bottom 12.
- the centrifuge housing 10 also accommodates a rotating cylindrical centrifuge drum 20.
- Also of the centrifuge drum 20 is only schematically indicated a corner region.
- ZuckerHollmasse is thrown off during operation, with syrup in the form of green drain and white drain passes through the jacket to the outside, on the inside of the wall 1 1 of the centrifuge housing 10th
- the green effluent first exiting from the centrifuge drum 20 also hits first on the inner wall 1 1, runs down the wall 1 1 and then runs into a groove in the form of an annular channel 30.
- This annular channel 30 is on the inside of the wall 1 1 circulating attached. He has a Ringkanalwandung 31 and a ring channel bottom 32.
- the Ringkanalwandung 31 is approximately parallel to the wall 1 1 of the centrifuge housing 10 and runs over the entire circumference by 360 ° with the wall 1 1 to.
- the annular channel bottom 32 is horizontal in the first approximation, but has a slope, so that the annular channel 30 has a lowest point.
- the inclination of the bottom 32 of the annular channel 30 is in most embodiments of the invention in the range of 2 ° to 30 °, preferably between 5 ° and 10 °.
- the green drain running in the annular channel 30 thus fills this annular channel 30 up to the upper edge of the annular channel wall 31.
- the green drain runs over the upper edge of the annular channel wall 31 and the overflowing part flows, then drops or drops onto the bottom 12 of the centrifuge housing 10.
- the capacity of the annular channel 30 is deliberately chosen so that the major part of the green drain runs in this way over the upper edge of the annular channel wall 31 and drips onto the bottom 12 of the centrifuge housing 10.
- a drain opening 41 is provided on or in the bottom 12 of the centrifuge housing 10. At this drain opening 41, which can be closed, a connecting line 51 is connected.
- connection line 51 leads to a receptacle 61.
- the green drain which has collected on the bottom 12 of the centrifuge housing 10, passes through the drain opening 41 and the connecting line 51 in the receptacle 61, which fills in this way with green drain and also contains no other substance.
- the bottom 12 of the centrifuge housing 10 may also be provided with a slope or be equipped with an inclination corresponding internals, which bundle the green drain at one point of the centrifuge housing 10.
- Another drain opening 42 is provided in the wall 1 1, in the region in which the annular channel 30 is located on the inside of the wall 1 1. This drain opening 42 is connected by means of a connecting line 52 with a second receptacle 62.
- FIG. 1 A corresponding closing device or shut-off arrangement 71 in the form of a valve is shown schematically in FIG.
- the blocking arrangement 71 prevents the drainage of the green drain located in the annular channel 30 at this time through the drainage opening 42 and the connecting line 52 into the receiving container 62, the receiving container 62 initially remains empty.
- a sensor 80 is integrated, which detects a physical value of the syrup flowing past here. This may in particular be the color of the syrup. For this there are characteristic color values, so a typical value for the color of a green drain is approximately 20,000 to 25,000 Icumsa units, abbreviated also IU (Icumsa units).
- the physical value detected by the sensor 80 ie the color
- the maximum value will, as tests have shown, be reached approximately when the phase of washing liquid addition to the sugar filling masses has been completed, and also at the moment when the continuously accelerating centrifuge drum has reached its maximum value after the acceleration process.
- the maximum value then remains constant for a period of time, from which it can be deduced that the green effluent remains unchanged during centrifugation and passes through the sensor 80.
- a threshold can be selected that is between about 60 and 85% of the previously reached maximum value of the color. If the magnitude of the physical value measured by the sensor 80, in this case the color, falls below the threshold value, then it is immediately clear that this is not one of the usual fluctuations that have often occurred before, but actually the expected turnover of Green drain to white drain that is just starting.
- the values of the sensor 80 are now transmitted wirelessly or by cable to a controller 81, which is also indicated only schematically in FIG. If the control device 81 receives this information and recognizes the change from green drain to white drain, the shut-off arrangement 71 is opened.
- the green drain located in the annular channel 30, that is not on the upper edge of the annular channel wall 31 on the bottom 12 is now running over the connecting line 52 into the receptacle 62, which thereby also fills with a limited amount of green drain, namely with a volume which is exactly the content of the annular channel 30 between the upper edge of the Ringkanalwandung 31, the annular channel bottom 32 and the wall 1 1 corresponds.
- the entire white effluent and the washing water with the dissolved sugar crystals is then supplied in the following time to the receptacle 62 in this way.
- the receptacle 62 thus contains a relatively well-defined mixture of green drain and white drain, which can be predetermined by the choice of the dimensions of the annular channel 30 and the choice of the height of the upper edge of the annular channel wall 31.
- mixing ratios defined here of approximately 10 to 20 parts of green effluent to approximately 90 to approximately 80 parts of white effluent can be achieved with precise precision. These ratios are significantly better and more precise than the blends that were conventionally possible with external, controlled valve circuits in separating a uniform drain from centrifuge housings.
- FIG. 2 shows a modified embodiment which largely takes over the ideas from the first embodiment and is also shown in a similar way.
- a centrifuge housing 10 in vertical section with a wall 1 1 and a bottom 12.
- a centrifuge drum 20 Within the centrifuge housing 10 is a centrifuge drum 20, from the green drain and later white drain on the inside of the wall 1 1 of the centrifuge housing 10 passes.
- annular channel 30 with a Ringkanalwandung 31 and a circular channel bottom 32 can be seen.
- the annular channel 30 also forms here a circumferential collecting channel for the first out of the centrifuge drum 20 outgoing green drain.
- a connecting line 53 is now also provided, which branches off from the connecting line 52 between the discharge opening 42 and the shut-off arrangement 71 and, to a certain extent, opens into the other connecting line 51 as a short-circuit line.
- This connection line 53 can be closed or shut off separately with an additional shut-off arrangement 72.
- a control device 81 a sensor 80 near the drain opening 42 in the connecting line 52 or 53 in front of the shut-off arrangement 71, which is in communication with a control device 81.
- the blocking arrangement 71 is closed.
- the shut-off assembly 72 is initially opened or alternatively closed for a short predetermined time. That means that in the Annular channel 30 of the green drain accumulates and finally runs over the upper edge of the annular channel wall 31 on the bottom 12 of the centrifuge housing 10 and similar to the first embodiment flows into the receptacle 61.
- the shut-off arrangement 72 is opened or left in the connecting line 53 via the control device 81.
- the shut-off 71 remains closed. It may then possibly abruptly the contents of the annular channel 30 are performed with the first captured there green drain through the connecting line 53 to the connecting line 51 and into the receptacle 61. Subsequently, with the ICUMSA value still falling further or, alternatively, in this case also correspondingly very short time clock after the preceding event, the shut-off arrangement 71 is now opened.
- the white drain which has now run into the annular channel 30 from above following the green drain, can now pass through the connecting line 52 and the opened shut-off arrangement 71 into the receiving container 62.
- the receptacle 62 now takes virtually only white drain.
- the shut-off arrangement 72 can remain open by the control device 81 until the sensor 80 transmits values, after which the green drain is replaced by white effluent.
- the conception of FIG. 2 thus leads to a nearly optimal separation from green drain to white drain.
- the receptacle 61 is in turn to 100% green drain, albeit two feed paths, while in the receptacle 62 is only white drain.
- FIG. 3 shows the time course of various values during the processing of a charge in the centrifuge drum 20. To the right, the time t is plotted in seconds. The value 0 denotes the moment of commencement of the filling of the centrifuge drum 20 with sugar filling compound of a new batch.
- washing water can also be a sugar solution from another processing stage.
- a third and particularly interesting curve now relates to the variation of the value of the color detected by the sensor 80.
- a relative value is plotted here for the purpose of illustration.
- the color value initially increases steeply and then slowly until it reaches the maximum value of 100% of the achieved color value. He stays there for some time and then drops off very steeply. The drop then flows again on a plateau, the amount of which depends on the type of Zucker Schollmasse, the processing stage, the amount of Zucker spallmasse and other criteria.
- the value is somewhere between a few% and about 60% of the maximum value.
- FIG. 4 shows a somewhat more detailed embodiment, which largely corresponds to the idea from the second embodiment in FIG.
- the amount of green drain 25 indicated by the arrow runs down the wall. It then fills down the drainage channel or the annular channel 30 until it has filled it up to the upper edge of the annular channel wall 31.
- the annular channel 30 rotates and its wall 31 may be formed by a cylindrical drum, which can stand as an installation in the interior of the cylinder housing 10 on a corresponding pedestal.
- the green drain 25 runs in the illustration in Figure 4 inwardly over the upper edge of the Ringkanalwandung 31 in an underlying, also channel-like receptacle 13 above the bottom 12. Thereafter, the green drain then runs through the drain opening 41 and the Connecting line 51 to the receptacle 61st
- the white drain can run via the shut-off arrangement 71 and the connecting device 52 into the receiving container 62 via the receiving opening 42 in the region of the annular channel 30, wherein the initially collected green drain before the white drain also occurs through a short-circuit connecting line 53 with a shut-off arrangement 72 can be discharged into the connecting line 51 and further into the receptacle 61.
- FIG. 5 also shows a further schematic illustration, from which it can be seen that the annular channel 30 has an inclined annular channel bottom 32 in order to be able to selectively supply the outlet opening 42 in the annular channel 30 to the respective contents.
- annular channel bottom 32 is not only inclined in itself, but that it is also higher in the figure 5 left sides of the wall 1 1 of the centrifuge housing 10 than on the right side shown in Figure 5 side of the wall 1 1.
- the annular channel bottom 31 also in circumferential orientation within the wall 1 1 has at least one lower region and correspondingly inclined portions, which lead the white drain and the green drain to predetermined drain openings 42.
- the drainage channel or the annular channel 30 is deliberately shown as double-walled.
- FIG. 6 shows a further modified embodiment, which is more complex in terms of apparatus but can still further perfect the already excellent results for the separation.
- This embodiment has, in addition to the annular channel 30 with its annular channel wall 31, a second annular channel 35 located underneath, with an annular channel wall 36.
- This second or lower annular channel 35 receives a lot of green drain or white drain, which runs over the upper edge of the Ringkanalwandung 31 and in turn can run on its own Ringkanalwandung 36 those volume fractions that exceed its capacity.
- a sensor 80 in the wall 1 1 above the drain opening 42 or in the connecting line 52/53 are arranged immediately following the drain opening 42.
- a control device 81 takes over the control of the shut-off arrangements 71, 72 and 73 as a function of the measured values of the sensor 80.
- the sensor 80 and the control device are here 81 not shown.
- a centrifuge housing 10 surrounds the centrifuge drum 20.
- a wall 1 1 of the centrifuge housing 10 is provided, on which impinge the centrifugal drum 20 thrown off syrup masses. These run down the wall 1 1.
- the green drain 25 passes the sensor 80.
- the sensor 80 measures a physical value that indicates, for example, the color or brightness or electrical conductivity of the passing syrup. It transmits these measured values to a control device 81 (not shown).
- shut-off arrangement 71 is a liftable and lowerable cover element which, in FIG. 7, is currently in the closed position. This means that this cover element of the shut-off arrangement 71 rests with a flat conical sealing surface on a stationary counter-cone. Since the shut-off 71 is thus in the closed position, the green drain 25 continues over the slope shown in a first receptacle 61st This receptacle 61 forms here an annular chamber, which is arranged below the centrifuge drum 20 annularly around the centrifuge housing 10.
- the control device 81 controls the lifting and lowering of the shut-off arrangement 71 as a function of the measured values of the sensor 80. Now runs instead of green drain 25 white drain 26 on the sensor 80 over, the lid-like shut-off 71 is raised. As a result, the shallow cone on the underside of the cover-like element separate from its counter-cone and releases access into the second receptacle 62.
- This is here also an annular chamber which extends around the outside around the first annular chamber of the first receptacle 61 around the centrifuge housing 10 outside.
- annular chambers shown in section represent only a portion of the receptacle 61, 62.
- the illustrated annular chambers are used primarily for initially separate recording and then forwarding of the green drain 25 and the white drain 26 receptacle 61, 62 or larger Volume ranges of these receptacles 61, 62 can be arranged below the range shown and / or outside of the centrifuge housing 10.
- the term "receptacle 61, 62" therefore, is to be understood as meaning all of these container elements provided for receiving the syrup draining from the centrifuge drum 20 separately according to the green drain 25 and the white drain 26.
