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

1 . A rotary machine for mixing, pumping or agitating a fluid comprising:
an impeller configured to act on the fluid; a drive unit 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; 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 is slidingly movable relative to the outer member for adjusting the length of the respective leg.

2 . The rotary machine in accordance with claim 1 , wherein each of the at least one leg comprises a mounting plate at the first end of a respective leg configured to mount the respective leg to a housing part of the rotary machine, and a base plate at the second end of the respective leg 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 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.

6 . The rotary machine in accordance with claim 5 , wherein the outer member has four side faces and two different and abutting side faces each include at least one pre-drilled hole.

7 . 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°.

8 . The rotary machine in accordance with claim 1 further comprising a connecting part fixed to the housing part of the rotary machine and configured to be connected to the at least one leg in a detachable manner.

9 . The rotary machine in accordance with claim 8 wherein a mounting plate is mountable to the connecting part by screws.

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

11 . The rotary machine in accordance with claim 10 , wherein the agitator is configured to be horizontally mounted to a wall of a vessel.

12 . 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; and mounting at least one leg of a support structure to a housing part of the rotary machine, 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.

13 . The method in accordance with claim 12 , 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.

14 . The method in accordance with claim 12 wherein the at least one leg includes exactly two legs for supporting the rotary machine.

15 . The method in accordance with claim 12 wherein the rotary machine is an agitator that is horizontally mounted.

16 . The rotary machine in accordance with claim 5 , wherein the outer member and the inner member have square cross sections.

17 . The rotary machine in accordance with claim 7 , wherein the mounting angle for each leg is between 70° and 80°.
