Definitions

the invention relates to a continuously operating sieve centrifuge, in particular a sugar centrifuge with two centrifugal drums arranged one above the other and connected to one another, each of which is connected to a centrifugal shaft rotating and driven about a vertical axis and both centrifugal drums are accommodated in a common housing.
the invention has for its object to provide a centrifuge of the type mentioned, with which the pre-spin compared to the post-spin is subject to a greater or the same size separation effect with the smallest footprint and washed and removed the centrifuge separately in both spin stages, and between the first and second Centrifugation a mashing can be provided. Furthermore, the aim is to avoid as far as possible the unbalances resulting from the unavoidable unequal distribution of the filling materials and to separate the green runoff and white runoff.
a centrifuge housing 1 with a centrifuge lid 2 and a centrifuge bottom 3 is one Cylinder wall 5 is provided for collecting the white drain separately from the green drain. Furthermore, a stop bushing 13 is provided on the centrifuge bottom 3, in which the centrifuge shaft 9 rotates freely without a guide, but which limits the deflection of the shaft in order to prevent the drum from striking. A movable air seal 13 is provided on the centrifuge lid 2, which prevents the entry of external air, but does not hinder the free movement of the centrifuge shaft 9 with regard to self-centering. At the upper end of the centrifuge shaft 9 there is a self-aligning bearing 14 with a motor 12 arranged above it.
the upper centrifugal drum 15 is fastened by means of a hub 16, on which there is a drum base 17 with a drum jacket 18 which is flared upwards.
an accelerator cone 19 is connected to the hub 16, an accelerator pot 36 of the accelerator cone 19 being filled from a filling device 20.
the filling compound reaches the lower area of the drum casing 18 and travels over the inside thereof to the outlet flange 21, where the dry-spun sugar is discharged.
a washing device 22 with nozzles sprays a washing liquid onto the migrating sugar layer, whereby the degree of purity of the sugar is increased.
the centrifuged mother syrup reaches a gutter 24 and is discharged via a discharge line 25.
the spun off sugar goes into channel 4.
the lower centrifugal drum 26 is fastened to the centrifuge shaft by means of a hub 39, wherein a spacer tube 30 is provided between the two centrifugal drums.
a spacer tube 30 is provided between the two centrifugal drums.
a washing device 31 is also inserted into the lower centrifugal drum.
the sugar spun out of the upper centrifugal drum 15 is subjected to a mashing liquid, for example a syrup of higher purity, and mashed in via a device 23 in the region of the outlet flange 21.
the sugar mass mashed into channel 4 in this way reaches the accelerator device 34 of the lower centrifugal drum 26 via a line 6.
the sugar layer migrates over the inside of the drum casing 28 and is thereby washed by means of the washing device 31.
the spun-off sugar thus reaches the annular space 35 via the outlet flange 29.
the spun-off syrup is collected on the inside of the cylinder plate 5 and collected in an annular space 7 formed by a further ring plate 8 and via the opening 37 and the line 32 and / or 10 dissipated.
the sugar discharged from the lower centrifugal drum 26 can be discharged dry and in this case is collected by the inner wall of the housing 1 and fed to a sugar failure channel 33.
the sugar discharged from the lower centrifugal drum 26 can also be mashed in.
the lines required for mashing and dissolving to supply the corresponding liquids are not shown because these devices are known per se. Both the mashed-in and the dissolved sugar are withdrawn via appropriate means, not shown, via channel 33.
the essence of the invention is to be seen in the fact that a filling compound can be spun twice in the smallest footprint and mashed in between the individual spinning processes, the transfer of the pre-spun and mashed sugar taking place automatically via mechanical devices.
the proposed solution avoids unbalance with all its disadvantageous consequences due to the novel arrangement of the drive, drums and bearings.
the pendulum suspended double drums work as a self-stabilizing gyro. Imbalances caused by unevenly distributed centrifugal material (filling mass) are compensated for by moving the centrifuge axis. The centrifuge runs more quietly than centrifuges with centrifugal drums that are positively driven.
the supply of the crystals spun off in the upper drum and mashed in with liquid via a single or multi-course straight or spiral channel to the accelerator pot of the lower drum ensures a screen spinner control using a stroboscope during production. This is particularly advantageous, since it allows the flow behavior to be observed and can be favorably influenced by appropriate regulation of the addition of syrup. This ensures a uniform and better quality of the end product.
Another advantage of the invention is that the replacement of damaged deck screens in the lower drum is possible in this embodiment without dismantling the centrifuge. Downtimes and the associated loss of production are reduced to a minimum.
Another advantage of the invention that cannot be overlooked is that energy can be saved by freely exchanging the rotating air masses from the upper and lower drums and vice versa compared to arranging the drums in separate rooms.
