Continuously operating centrifuge

摘要

A continuously operating centrifuge for centrifuging sugar massecuites has an upwardly flaring conical sieve basket (20) which rotates about a vertical axis (16). A product distributor (40) flares downwardly and extends into the bottom region of the sieve basket (20). The product distributor (40) is substantially coaxial with respect to the sieve basket (20), has a discharge rim and rotates about the same vertical axis (16) as the sieve basket (20). Within and in the upper region of the product distributor (40), there is provided a distributor pot (30) which serves as a feeding device for the sugar massecuites in the axial region of the centrifuge. The peripheral wall of the product distributor (40) is divided up into a plurality of ring elements (41, 42, 43) which overlap in the direction of the axis (16) and the internal diameters of which differ from each other. A bell (50) surrounds the product distributor (40) and flares conically downwardly. A device (61, 62) incorporating air directing elements is provided between at least two of the ring elements (41, 42, 43) of the product distributor (40).

主权项

1. A continuously operating centrifuge for centrifuging sugar massecuites, comprising
a) a conically upwardly flaring sieve basket which rotates about a vertical axis, b) a downwardly flaring product distributor which extends down to the bottom region of the sieve basket, is substantially coaxial with the sieve basket, forms a discharge rim at the bottom thereof and rotates about the same vertical axis as the sieve basket, c) a distributor pot which is disposed within and in the upper region of the product distributor and serves as a feeding device for the sugar massecuites in the axial region of the centrifuge, d) the product distributor including a peripheral wall having a plurality of separate annular ring elements which overlap in the direction of the axis, having an annular gap defined between adjacent ones thereof and the inside diameters thereof differ from each other, e) a conically downwardly flaring bell which surrounds the product distributor, characterized, in that a device having air directing elements is disposed within the annular gap defined between at least two adjacent annular ring elements of the product distributor, and in that the device having air directing elements comprises a base planar annular metal sheet, and a multiplicity of sheet metal surface areas that issue upwardly from the base planar annular metal sheet to form upwardly extending wings or blades.
