Definitions

the invention relates to a continuously operating sieve centrifuge, in particular a sugar centrifuge, with two driven centrifugal drums which can be rotated about a vertical axis and are arranged at a distance above one another in a common housing, with the outlet flange of the upper centrifugal drum being assigned a device for supplying a mashing liquid and a stationary, the centrifuged sugar catching collecting device are connected, from which at least one discharge line for the mashed sugar mass leads into an acceleration device of the lower centrifugal drum.
An accelerator device is filled by a filling device within the upper centrifugal drum.
the filling compound reaches the lower area of the drum casing and travels over the inside of it to the flange of the upper centrifugal drum, where the dry spun sugar is discharged.
a washing device with nozzles sprays a washing liquid onto the migrating sugar layer, which increases the degree of purity of the sugar.
the centrifuged mother syrup enters a gutter and is discharged via a discharge line.
the spun off sugar is subjected to a mashing liquid, for example a syrup of higher purity, and mashed in via a device in the area of the outlet flange.
the mashed-in sugar mass then reaches the above-mentioned discharge line eccentrically into the above-mentioned acceleration device of the lower centrifugal drum.
the sugar layer migrates over the inside of the drum casing and is washed by means of a washing device.
the spun-out sugar enters an annular space via a discharge flange of the lower centrifuge drum, while the spun-off syrup is discharged separately.
the spun off sugar can be discharged dry and in this case is collected by the inner wall of the housing and fed to a sugar dropout channel.
the sugar discharged from the lower centrifugal drum can also be mashed in.
the invention has for its object to improve the known screen centrifuge in terms of its customization options.
This object is achieved according to the invention by a drive with independently adjustable speeds of the two centrifugal drums.
the screen centrifuge according to the invention enables the centrifugal force of each centrifugal drum to be changed independently of that of the other in order to adapt it to the requirements of the process.
the upper centrifugal drum has a larger diameter and thus a larger screen area than the lower centrifugal drum, and if the upper centrifugal drum is driven at a higher number of revolutions than the lower centrifugal drum.
This procedure can be optimized simply by replacing the V-belt pulleys and thus also by the operator himself.
two discharge lines arranged offset by 180 ° are provided, which open centrally via a common outlet connection in the acceleration device of the lower centrifugal drum.
the sugar centrifuge shown comprises two centrifugal drums 1, 2 spaced one above the other, which are arranged in a common housing 3 and can be rotated about a common vertical axis 4.
the outlet flange 5 of the upper centrifugal drum 1 is assigned a device 6 for supplying a mashing liquid.
the outlet flange 5 is followed by a stationary collecting device 7 in the form of a mashing cone which collects the spun off sugar. From this collecting device 7, two discharge lines 8, which are offset by 180 °, lead centrally via a common outlet connection 8a into an acceleration device 9 of the lower centrifugal drum 2.
the upper centrifugal drum 1 is assigned an upper drive motor 10 and the lower centrifugal drum 2 a lower drive motor 11.
the rotation is transmitted via a V-belt drive 12 and interchangeable V-belt pulleys 13, 14.
the upper centrifugal drum 1 is mounted in an upper self-aligning bearing 15, the lower centrifugal drum 2 in a lower pillow block 16.
