Abstract
The invention may utilize shaft horsepower for rotating cylinders to move a fluid in an axial direction within the cylinder. The cylinder may comprise a spiral blade on or in its inner surface with a pitch relative to a central axis of the cylinder. The blade's pitch may be variable or uniform with respect to the central axis. In some applications, plural blades may be positioned within the cylinder. The invention is particularly suitable for imparting kinetic energy sufficient to assist with the evacuation of condensate from a paper dryer cylinder with reduced or no blow through steam. The invention also has applications for spinner wheels.
Claims18
A wheel for making mineral wool or metal wool, the wheel comprising:
- a. a hollow, cylindrical shell having an outer surface, an annular inner surface, an inner diameter, and a first end and a second end;
- wherein the shell is rotatable about a central axis;
- wherein the outer surface is configured to receive molten material for making mineral wool or metal wool;
- b. a cavity within the hollow shell defined at least by the inner surface of the shell;
- c. an inlet and an outlet in fluid communication with the cavity;
- wherein the inlet and the outlet are each proximate to the second end of the shell;
- d. a central member comprising a plurality of inlet apertures in fluid communication between the inlet and the cavity, wherein the plurality of inlet apertures are proximate to the first end of the shell;
- e. a helical blade disposed within the cavity around the central member;
- wherein at least a portion of the blade is positioned along the central axis between the plurality of inlet apertures and the outlet for imparting a force on a fluid in the cavity to move the fluid toward the outlet.
