Innovations in centrifuges for the continuous separation of solid bodies from a mixture

of liquids and solids.

Fatenürt in the German Empire from May 6, 1882.

With the centrifuge, which is specially designed to separate the sugar mass from the syrup and Ejection of the moisture that is extracted from the diffusers. Beet pulp is still contained, is to serve, the separation of solid and liquid bodies takes place from the above-mentioned mixtures in a continuous and not in an interrupted one Way, as with the previously known arrangements for the mentioned purpose serving centrifuges, which had to be put into operation each time for emptying.

The centrifuge is set up in such a way that the in the constantly flowing mass contained solid body in the dry state in the measure over the upper edge the drum as the feed of new mass' takes place in the centrifuge.

On the outside of the jacket a, FIGS. 1, 2 and 3, two symmetrical channels bb are cast, which completely encompass the jacket α at the top and taper at the bottom to the width hh , FIGS. 2 and 3. This creates an all-round ring-shaped channel at the top into which the solid objects thrown over the upper edge of the drum must fall. The latter emerge through the openings cc with the width hh, FIGS. 2 and 3.

In order to prevent the solid parts from being thrown out of the centrifuge, the channels b are covered by an annular plate d which is fastened to the flange of the former.

The vertical distance of the plate d from the upper edge of the drum e is different depending on the use for syrup or beet pulp.

The drum attached to the cone / has a beaded edge with which it grips over the upper edge of the shell α . The conical casing g is attached to the plate d concentrically to the drum e , the lower edge of which creates a clearance of a suitable height between it and the bottom of the centrifuge drum. This prevents the mass from rising too early on the circumference of the drum; on the contrary, it is slowly propelled upwards from the lowest part of the drum, in order to be able to completely eject the liquid.

The process of separating solid bodies from a mixture of solid and liquid bodies takes place in such a way that, during the rapid rotation of the drum e, the liquid is priced out of the constantly flowing mixture as a result of the centrifugal force and through the holes in the drum shell into the inner space of the Mantle α is thrown, from where it can drain.

The solid bodies, such as schnitzel or Sugar mass, due to the effect of the centrifugal force, rise slowly upwards on the slightly inclined wall of the drum e , whereby the last remains of the liquid are still priced out, then fly between the plate d and the bent edge of the drum

mel e into the aforementioned annular channels bb and exit through the openings cc .

Claims (1)

Patent claim: A centrifuge, which is specially designed to separate the sugar crystals from the syrup and for centrifuging out the moisture contained in the beet pulp removed from the diffusers is still contained, is intended to serve, and is characterized by: a) by the arrangement of the channels bb tapering from top to bottom, which are attached to the outside of the fixed casing α and covered by a plate d which partially overlaps the centrifuge drum; b) through the use of a fixed, downwardly tapering conical jacket g attached to the plate d while simultaneously using the channels bb mentioned under a), plate d, the flanged centrifuge drum e for the continuous operation of such centrifuges, essentially as described and for the above purpose.
