Abstract

A plate separator for separating a substance from a substance mixture, with a separator device and an electric motor for rotary driving of the separator device. The separator device is coupled to the electric motor in a rotationally fixed manner. The electric motor is configured as an external rotor and has an inner-lying stator and an outer-lying rotor in the radial direction with respect to an axis of rotation. The separator device is fastened to the rotor and extends outward from the rotor in the radial direction. The stator is arranged, as viewed in the axial direction with respect to the axis of rotation, at least partially overlapping with the separator device.

First claim

The invention claimed is:

1. A plate separator for separating a substance from a substance mixture, comprising;
a separator device and an electric motor for rotary driving of the separator device, wherein
the separator device is coupled to the electric motor in a rotationally fixed manner, wherein
the electric motor is configured as an external rotor and has an inner-lying stator and an outer-lying rotor in the radial direction with respect to an axis of rotation of the electric motor, wherein
the separator device is fastened to the rotor and extends outward from the rotor in the radial direction, wherein
the stator is arranged, as viewed in the axial direction with respect to the axis of rotation, at least partially overlapping with the separator device, wherein
the rotor is mounted rotatably by a bearing shaft, which engages through the stator at least partially in the axial direction.

2. The plate separator according to claim 1 , wherein the separator device has a plurality of plate elements, which are arranged coaxially with respect to one another.

3. The plate separator according to claim 2 , wherein the plurality of plate elements each have an annular form, wherein they each have an inner-lying first end in the radial direction and an outer-lying second end in the radial direction, and wherein the plurality of plate elements are each arranged on the rotor at the first end in a rotationally fixed manner.

4. The plate separator according to claim 3 , wherein the first end of at least one of the plurality of plate elements is arranged within a region of the axis of rotation over which the stator extends axially, in the transverse direction relative to the axis of rotation.

5. The plate separator according to claim 3 , wherein the plurality of plate elements each have a first annular region, which extends from the first end radially in the direction of the second end, wherein the plurality of plate elements are essentially flat in form in the first annular region and are arranged perpendicular to the axis of rotation.

6. The plate separator according to claim 5 , wherein the substance mixture can be fed to the plurality of plate elements in the region of the first annular region.

7. The plate separator according to claim 5 , wherein the plurality of plate elements each have a second annular region, which respectively adjoins the first annular region and extends up to the second end, wherein the plurality of plate elements have essentially the form of a conical section in the second annular region and enclose an angle of less than 90° and greater than 0° with the axis of rotation.

8. The plate separator according to claim 2 , wherein the plurality of plate elements are formed in one piece with the rotor.

9. The plate separator according to claim 1 , wherein a housing, which is firmly connected to the stator.
