Disc for industrial plants

摘要

An industrial plant such as a disc dryer is constructed or retro-fitted with discs each comprising two annular plates connected to one another around their outer edges, each plate comprising one or more integral ribs extending between its inner edge and outer edge. The integral ribs may comprise folds in the annular plates, and each plate may be formed from a length of sheet material, by roll forming for example, so that the integral ribs are deeper towards the inner peripheral edge than the outer peripheral edge of the annular plates forming the disc.

主权项

1. An industrial plant comprising:
a shaft having a hollow interior; at least one hollow disc coupled to the shaft, the hollow disc comprising two annular plates continuously connected to one another around outer edges of the annular plates, the hollow disc comprising interior space between the two annular plates closed to the exterior of the disc at the continuously connected outer edges of the annular plates, each annular plate comprising integral ribs extending substantially radially between an inner edge and the outer edge of the annular plate, spaced around the annular plate, and formed from folds in the annular plate, the inner edge of the two annular plates being coupled around the shaft and spaced apart from one another; and at least one aperture in the shaft between the plates of the disc so that the hollow interior of the shaft is in fluid communication with an interior space between the two annular plates of the disc.
