Separator disc, combination of separator disc stack and distributor, and centrifuge

A device comprising:

• a distributor that is rotatable in operation;
• and
• a separator disc stack of separator discs of a separator rotatable with the separator disc stack in the operation,
• wherein each of the separator discs of the separator disc stack have
• a frustoconical shell-like main body having an inner circumference, an outer circumference, an inner surface, an outer surface, and one or more spacer elements,
• wherein one or more hollow protrusions are formed on the frustoconical shell-like main body, wherein the one or more hollow protrusions have a greater axial extension than the one or more spacer elements, so that, in the separator disc stack, the one or more hollow protrusions of an adjacent separator disc in the separator disc stack are engageable into one another in a form-fitting manner,
• wherein the distributor has a distributor base and a distributor shaft,
• wherein a lowermost separator disc of the separator disc stack rests on the distributor base, and
• wherein further separator discs of the separator disc stack are stacked on the lowermost separator disc around the distributor shaft.

A centrifuge comprising:

• a drum;
• a distributor that is rotatable in operation;
• and
• a separator disc stack of separator discs of a separator rotatable with the separator disc stack in the operation, wherein the distributor and separator disc stack are arranged in an interior of the drum,
• wherein each of the separator discs of the separator disc stack have
• a frustoconical shell-like main body having an inner circumference, an outer circumference, an inner surface, an outer surface, and one or more spacer elements,
• wherein one or more hollow protrusions are formed on the frustoconical shell-like main body, wherein the one or more hollow protrusions have a greater axial extension than the one or more spacer elements, so that, in the separator disc stack, the one or more hollow protrusions of an adjacent separator disc in the separator disc stack are engageable into one another in a form-fitting manner,
• wherein the distributor has a distributor base and a distributor shaft,
• wherein a lowermost separator disc of the separator disc stack rests on the distributor base, and
• wherein further separator discs of the separator disc stack are stacked on the lowermost separator disc around the distributor shaft.
