## Abstract

The disclosure relates to an axial-flow centrifugal separator for separating particles from a dispersion, in particular a suspension, which contains the particles and a fluid, the separator including a hollow cylindrical pipe section for conducting the dispersion in a conducting direction. An inner wall of the hollow cylindrical pipe section may have an internal thread, the lead angle of which increases in the conducting direction.

## Claims

### Claim 1

A uniflow cyclone separator for separating particles from a dispersion comprising the particles and a fluid, the uniflow cyclone separator comprising:
a hollow-cylindrical pipe section for guiding the dispersion in a guiding direction,
wherein an inner wall of the hollow-cylindrical pipe section comprises a female thread having an angle of slope increasing in the guiding direction, and
wherein the female thread forms a helix along the guiding direction.

### Claim 2 (depends on 1)

The uniflow cyclone separator in accordance with claim 1,
wherein the female thread comprises a plurality of notches between 4 notches and 20 notches.

### Claim 3 (depends on 1)

The uniflow cyclone separator in accordance with claim 1,
wherein the angle of slope increases in the guiding direction from a minimum angle of slope that is at least 15° to a maximum angle of slope that is no more than 60°.

### Claim 4 (depends on 1)

The uniflow cyclone separator in accordance with claim 1,
further comprising a hollow-cylindrical second pipe section arranged after the hollow-cylindrical pipe section in the guiding direction,
wherein a damming body with guide blades extending radially outwards is attached to and arranged in the hollow-cylindrical second pipe section, and
wherein the guide blades are spaced apart from an inner wall of the hollow-cylindrical second pipe section.

### Claim 5 (depends on 4)

The uniflow cyclone separator in accordance with claim 4,
wherein the guide blades are tilted with respect to regarding the guiding direction and comprise the same angle of slope as the female thread.

### Claim 6 (depends on 4)

The uniflow cyclone separator in accordance with claim 4,
wherein a length of the guide blades in the guiding direction diminishes with increasing distance to the inner wall.

### Claim 7 (depends on 4)

The uniflow cyclone separator in accordance with claim 4,
wherein the hollow-cylindrical second pipe section is widened at the side facing away from the hollow-cylindrical pipe section.

### Claim 8 (depends on 1)

The uniflow cyclone separator in accordance with claim 1,
further comprising a hollow-cylindrical third pipe section further comprising a hollow-cylindrical third pipe section arranged before the hollow-cylindrical pipe section in the guiding direction,
wherein a further damming body having further guide blades extending radially outwards is attached to and arranged in the hollow-cylindrical third pipe section, and
wherein the further guide blades are attached to an inner wall of the hollow-cylindrical third pipe section.

### Claim 9 (depends on 8)

The uniflow cyclone separator in accordance with claim 8,
wherein the further guide blades are at least sectionally tilted with respect to the guiding direction.

### Claim 10 (depends on 1)

The uniflow cyclone separator in accordance with claim 1,
further comprising a separation chamber arranged after the hollow-cylindrical pipe section in the guiding direction,
the separation chamber comprising a separation pipe being arranged coaxially to the hollow-cylindrical pipe section,
the separation pipe having an inner diameter which is smaller than the inner diameter of the hollow-cylindrical pipe section and circumferentially being surrounded by a collecting chamber.
