Abstract
Systems and methods for bearing housings are disclosed. A labyrinth seal bearing housing includes: a first seal element that is structured and arranged to be connected to a wall of a mixing vessel; a second seal element that is structured and arranged to be connected to a rotatable shaft; and a bearing support that is structured and arranged to be connected to the first seal element. The second seal element is configured to rotate relative to the first seal element and the bearing support. The first seal element and the second seal element are structured and arranged to create a tortuous flow path between an exterior and an interior of the mixing vessel.
Claims17
A labyrinth seal bearing housing, comprising:
- a bearing support having a first end and a second end;
- a first seal element covering the first end of the bearing support, the first seal element including a first annular inner flange and a first annular outer flange encircling a rotatable shaft;
- a cover covering the second end of the bearing support;
- a bearing for connection to the rotatable shaft, the bearing at least partially located in a circular recess in the second end of the bearing support and beneath said cover;
- a second seal element that can be connected to the rotatable shaft, the second seal element located within the bearing support when the bearing and second seal are connected to the rotatable shaft, the second seal element including a second annular inner flange and a second annular outer flange encircling the rotatable shaft;
- wherein the second annular inner flange extends between the first annular inner flange and the first annular outer flange;
- wherein the first annular outer flange extends between the second annular inner flange and the second annular outer flange;
- and
- wherein the first seal element and the second seal element form a tortuous flow path between them when the bearing and second seal are connected to the rotatable shaft.
A system, comprising:
- a rotatable shaft;
- a bearing support having a first end and a second end;
- a first seal element covering the first end of the bearing support, the first seal element including a first annular inner flange and a first annular outer flange encircling the rotatable shaft;
- a cover covering the second end of the bearing support;
- a bearing connected to the rotatable shaft, the bearing at least partially located in a circular recess in the second end of the bearing support and beneath said cover;
- a second seal element connected to the rotatable shaft and located within the bearing support, the second seal element including a second annular inner flange and a second annular outer flange encircling the rotatable shaft;
- wherein the second annular inner flange extends between the first annular inner flange and the first annular outer flange;
- the first annular outer flange extends between the second annular inner flange and the second annular outer flange;
- and
- wherein the first seal element and the second seal element form a tortuous flow path between them.
