Abstract
A dryer drum for a paper making machine with a shell and end heads and steam delivery means and a plurality of headers extending axially and uniformly circumferentially spaced a relatively short length each carrying a row of dipper straws projecting adjacent the inner surface of the shell with the headers fixed to the shell surface and flexible tubes connecting the headers to a main conduit for removal of the condensate.
Claims1
A dryer drum for a paper making machine comprising in combination:
- a rotary mounted hollow cylindrical drum shell with supporting end heads;
- means for delivering steam into the interior of the shell for heating the shell and with condensate forming on the inner surface of the shell;
- a plurality of relatively short length headers extending generally axially within the drum and uniformly spaced from each other around the circumference of the drum overlapping at their ends;
- a row of dipper straws projecting radially outwardly from each of the headers and relatively uniformly spaced therealong with open ends positioned adjacent the inner surface of the shell for withdrawing condensate through the straws up into the headers;
- means rigidly mounting the headers in their respective positions to the inner surface of the shell;
- means for adjusting the position of the open end of the straws so as to position them uniformly spaced from the inner surface of the shell to maintain a uniform thickness in the layer of condensate rimming the shell surface;
- a conduit means extending from within the shell to the exterior thereof for removal of condensate;
- and flexible tubes connecting each of the headers to the conduit means for conducting the condensate from the headers to the conduit.
