Abstract

A rotary machine for mixing, pumping or agitating a fluid includes an impeller for acting on the fluid, a drive unit for rotating the impeller around a rotation axis, a drive shaft connecting the impeller with the drive unit, a mounting flange for fastening the rotary machine to a wall of a vessel, and a support structure for supporting the rotary machine, the support structure comprising at least one leg, each leg extending in a vertical plane from a first end along a longitudinal axis to a second end, each leg including an outer member and an inner member coaxially arranged in the outer member, and the inner member slidingly movable relative to the outer member for adjusting the length of the respective leg. In addition, a method of mounting a rotary machine for mixing, pumping or agitating a fluid to a wall of a vessel is proposed.

First claim

The invention claimed is:

1. A rotary machine for mixing, pumping or agitating a fluid comprising:
an impeller configured to act on the fluid;
a drive unit including a drive motor and configured to rotate the impeller around a rotation axis;
a drive shaft connecting the impeller with the drive unit;
a mounting flange configured to fasten the rotary machine to a wall of a vessel;
a housing part disposed around the drive shaft and including a connecting part, the connecting part having a first side connected to the housing part and a second side, the second side being opposite the first side and being substantially planar, and the drive motor radially offset and detachably connected to the housing part; and
a support structure configured to support the rotary machine, the support structure comprising at least one leg, each of the at least one leg extending in a vertical plane from a first end along a longitudinal axis to a second end, each of the at least one leg comprising an outer member and an inner member coaxially arranged in the outer member, the inner member slidingly movable relative to the outer member for adjusting the length of the respective leg, each of the at least one leg comprising a mounting plate at the first end of a respective leg, the mounting plate being substantially planar and configured to detachably mount to the second side of the connecting part of the housing part to fixedly mount the respective leg to the housing part of the rotary machine.

2. The rotary machine in accordance with claim 1 , wherein a base plate at the second end of the respective leg is configured to connect the leg to a foundation or the ground.

3. The rotary machine in accordance with claim 1 , wherein the outer member comprises at least one pre-drilled hole configured to receive a securing element.

4. The rotary machine in accordance with claim 2 , wherein a plane in which the mounting plate extends and the longitudinal axis of the leg include a mounting angle that is different from 90 degrees for each leg.

5. The rotary machine in accordance with claim 4 , wherein the at least one leg includes two legs, and the mounting angle for each leg is between 60° and 85°.

6. The rotary machine in accordance with claim 1 , wherein the outer member and the inner member have rectangular cross sections in a section perpendicular to the longitudinal axis of the at least one leg.

7. The rotary machine in accordance with claim 6 , wherein the outer member has four side faces and two different and abutting side faces each include at least one pre-drilled hole.

8. The rotary machine in accordance with claim 6 , wherein the outer member and the inner member have square cross sections.

9. The rotary machine in accordance with claim 5 , wherein the mounting angle for each leg is between 70° and 80°.

10. The rotary machine in accordance with claim 1 wherein the mounting plate is mountable to the connecting part by screws.

11. The rotary machine in accordance with claim 1 , wherein the rotary machine is an agitator configured to mix or agitate a fluid.

12. The rotary machine in accordance with claim 11 , wherein the agitator is configured to be horizontally mounted to a wall of a vessel.

13. The rotary machine in accordance with claim 1 , wherein the first side of the connecting part includes a first side part and a second side part, the first side part abuts the housing part and has a contour that matches an outer contour of the housing part, and the second side part extends tangentially from the outer contour of the housing part.

14. A method of mounting a rotary machine for mixing, pumping or agitating a fluid to a wall of a vessel comprising:
fastening a mounting flange of the rotary machine to the wall of the vessel;
fixedly mounting at least one leg of a support structure to a connecting part of a housing part of the rotary machine with a mounting plate, the connecting part having a first side connected to the housing part and a second side, the second side being opposite the first side and being substantially planar, the mounting plate being substantially planar and capable of being detached from the second side of the connecting part of the housing part, and including extending the at least one leg by moving an inner member of the at least one leg relative to a coaxially arranged outer member of the at least one leg along a longitudinal axis of the at least one leg until a base plate of the leg contacts a foundation, and fixing the inner member to the outer member of the at least one leg; and
detachably connecting a drive motor to the radial side of the housing part.

15. The method in accordance with claim 14 , wherein fixing the inner member to the outer member of the at least one leg comprises
selecting one of a plurality of pre-drilled holes in the outer member, using the selected hole for generating a perforation extending through an entirety of the at least one leg, inserting a securing element into the perforation for fixing the inner member to the outer member.

16. The method in accordance with claim 14 wherein the at least one leg includes exactly two legs for supporting the rotary machine.

17. The method in accordance with claim 14 wherein the rotary machine is an agitator that is horizontally mounted.

18. The method in accordance with claim 14 , wherein the first side of the connecting part includes a first side part and a second side part, the first side part abuts the housing part and has a contour that matches an outer contour of the housing part, and the second side part extends tangentially from the outer contour of the housing part.
