Also included is a plurality of conical discs super-imposed on one another and having disc bores forming at least one rising channel in the disc stack. Further included is a drum, a distributor and a lower base section which expands radially, and on which lower base section are one or more distributor channels. ## Claims ### Claim 1 A separator, comprising: a vertical axis of rotation; a drum having solids discharge openings and a conical centrifugal space; a disc stack located in the conical centrifugal space and including a plurality of conical discs super-imposed on one another, the conical discs having disc bores forming at least one rising channel in the disc stack; a drum; a distributor including a distributor shaft concentrically surrounding a drum axis of the drum, and further including a lower base section which expands radially, and on which lower base section are one or more distributor channels; a diameter of the at least one rising channel inside the disc stack, located above the disc which is the lowest disc in a flow direction, is one or both of a) not constant and b) sloped with respect to the drum axis; and the one or more distributor channels are not radially oriented with respect to the drum axis. ### Claim 2 (depends on 1) The separator according to claim 1, wherein distributor bores forming the distributor channels are oriented relative to a radial line through the drum axis in a laggingly sloped manner in a radially interior bore section against a rotating direction of the drum. ### Claim 3 (depends on 1) The separator according to claim 1, wherein the one or more distributor channels is located in a bore section leading into the drum, which bore section is oriented upward in the drum and leads out directly below one of the at least one channels of the disc stack into the drum. ### Claim 4 (depends on 1) The separator according to claim 1, wherein an angle between the one or more distributor channels and a radial line starting at an inner circumference of the one or more distributor channels is between 15 and 85°. ### Claim 5 (depends on 1) The separator according to claim 1, wherein the one or more distributor channels includes an outlet which extends tangentially either in or against a rotating direction of the drum. ### Claim 6 (depends on 1) The separator according to claim 1, wherein a geometry of the disc bores of the at least one rising channel varies in the at least one rising channel such that, during an operation, gaps between the discs are uniformly charged with liquid over an entire height of the disc stack. ### Claim 7 (depends on 1) The separator according to claim 1, further including a piston valve for opening and closing the solids discharge openings. ### Claim 8 (depends on 1) The separator according to claim 1, wherein the diameter of the at least one rising channel changes in steps over a distance of several discs. ### Claim 9 (depends on 1) The separator according to claim 1, wherein the diameter of the at least one rising channel changes continuously from one disc to the next disc. ### Claim 10 (depends on 1) The separator according to claim 1, wherein the diameter of the at least one rising channel decreases in a flow direction. ### Claim 11 (depends on 1) The separator according to claim 1, wherein a geometry of the disc bores changes from one disc to the next disc. ### Claim 12 (depends on 1) The separator according to claim 1, wherein the discs bores have a polygonal shape. ### Claim 13 (depends on 1) The separator according to claim 1, wherein the disc bores have a round shape. ### Claim 14 (depends on 1) The separator according to claim 1, wherein the disc bores have a curved shape. ### Claim 15 (depends on 1) The separator according to claim 1, wherein each of the at least one rising channel includes several disc bores. ### Claim 16 (depends on 1) The separator according to claim 1, wherein the disc bores of each of the at least one rising channel form a perforated pattern in the discs. ### Claim 17 (depends on 1) The separator according to claim 1, wherein the at least one rising channel is oriented to be sloped with respect to the drum axis. ### Claim 18 (depends on 1) The separator according to claim 1, wherein the at least one rising channel extends in a curved manner in the disc stack. ### Claim 19 (depends on 1) The separator according to claim 1, wherein the at least one rising channel includes a groove that is oriented asymmetrically with respect to a bisecting line of a disc segment to which the groove is assigned. ### Claim 20 (depends on 1) The separator according to claim 1, wherein the at least one rising channel includes a groove that is oriented to be laterally offset with respect to a bisecting line of a disc segment to which the groove is assigned and which is bounded by one or more of webs and lugs. ### Claim 21 (depends on 1) The separator according to claim 1, wherein the discs are placed on radial webs of the distributor shaft, and a discharge channel in the disc stack or a groove in the distributor shaft for the discharge is oriented asymmetrically with respect to a bisecting line of a disc segment. ### Claim 22 (depends on 1) The separator according to claim 1, wherein the at least one rising channel is for feeding product into the disc stack. ### Claim 23 (depends on 1) The separator according to claim 1, wherein the at least one rising channel is a discharge channel for discharging a liquid phase from the disc stack. ### Claim 24 (depends on 23) The separator according to claim 23, wherein the at least one discharge channel is constructed close to an inner circumference or close to an outer circumference of the disc stack inside the disc stack. ### Claim 25 (depends on 1) The separator of claim 1, wherein an angle between the one or more distributor channels and a radial line starting at an inner circumference of the at least one distributor channel is between 25° and 65°. ### Claim 26 (depends on 1) The separator of claim 1, wherein the one or more distributor channels includes an outlet which extends tangentially in an upward direction in the drum.
