Abstract

A centrifugal separation apparatus is disclosed. The centrifugal separation apparatus comprises a rotary drum, wherein an inlet opening and an outlet opening are respectively defined on opposite ends of the rotary drum along a central axis of the rotary drum. A fixing rod is disposed on the central axis, a baffle plate is disposed on the fixing rod, and a distance from each point on an edge of the baffle plate to the central axis is greater than a radius of the outlet opening.

First claim

What is claimed is:

1 . A centrifugal separation apparatus, comprising:
a rotary drum having an inlet opening and an outlet opening defined at ends of the rotary drum along a central axis of the rotary drum; a fixing rod disposed along the central axis; and at least one baffle plate disposed on the fixing rod, wherein a distance from each point on an edge of the at least one baffle plate to the central axis is greater than a radius of the outlet opening.

2 . The centrifugal separation apparatus of claim 1 , wherein the rotary drum is cylindrical and defines a chamber therein, and the inlet opening and the outlet opening are respectively defined at two ends of the chamber, and communicate with the chamber.

3 . The centrifugal separation apparatus of claim 1 , wherein the at least one baffle plate comprises a plurality of baffle plates disposed on the fixing rod and spaced from each other.

4 . The centrifugal separation apparatus of claim 3 , wherein the plurality of baffle plates are planar structures.

5 . The centrifugal separation apparatus of claim 4 , wherein the plurality of baffle plates are perpendicular to the central axis.

6 . The centrifugal separation apparatus of claim 4 , wherein the plurality of baffle plates are circular plates having centers located on the central axis.

7 . The centrifugal separation apparatus of claim 3 , wherein a spacing distance between any two adjacent baffle plates is in a range from about half to about twice of an inner radius of the rotary drum.

8 . The centrifugal separation apparatus of claim 1 , wherein the distance is in a range from about ½ to about ⅘ of an inner radius of the rotary drum.

9 . The centrifugal separation apparatus of claim 1 , wherein a center of gravity of the baffle plate is located on the central axis.

10 . The centrifugal separation apparatus of claim 1 , wherein the fixing rod is a solid structure.

11 . The centrifugal separation apparatus of claim 1 , wherein the fixing rod is configured to rotate with the rotary drum.

12 . The centrifugal separation apparatus of claim 1 , wherein the fixing rod is fixed relative to rotation of the rotary drum.

13 . The centrifugal separation apparatus of claim 1 , further comprising a bearing seat and a liquid inlet device, wherein one end of the rotary drum where the inlet opening is defined is installed in the bearing seat, the liquid inlet device is connected with the bearing seat, and communicates with the inlet opening, and the fixing rod is fixed on the liquid inlet device.

14 . The centrifugal separation apparatus of claim 1 , wherein a rotation speed of the rotary drum is equal to or greater than 10000 revolutions per minute.

15 . The centrifugal separation apparatus of claim 1 , being a tubular centrifuge.
