UNITED STATES PATENT WILLIAM A. HARTY, OF BLASDELL, NEW YORK, AND FRANK W. MOORE, OF THOROLD,
ONTARIO, CANADA.
ROTARY DRIER.
Application filed April 13, 1923. Serial No. 631,904.
To all whom it may concern Be it known that we, l/VILLIAM A. HARTY, a citizen of the United States, and FRANK TV. MOORE, a subject of George V, King of England, residing at Blasdell, county of Erie, State of N ew York, and Thorold, Province of Ontario, Dominion of Canada, respectively, have invented certain new and useful Improvements in Rotary Driers, of
which the following is a specification.
This invention relates to rotary driers, and consists in the novel construction, combination and relation of parts described and illustrated in the accompanying specification and drawings, and particularly pointed out in the appended claims.
According to our invention, the drier comprises a rotatable drier shell into which the material to be dried is adapted to be fed and a heating pipe disposed within and rotating with said shell.
1 Preferably the drier is self-loadlng in action, the intake end of the shell being provided with an annular series of spaced loading scoops which pick up the material to be dried as the shell rotates and deposit it within the drier shell. To insure proper distribution of the material throughout the length of the drier,'the inner face of the shell is provided with a longitudinal series of spaced feed ribs which are bent to raise the material to be dried allowing the material to fall in direct contact to a certain extent, with the heating pipe as said shell rotates.
Our drier is light in construction and comparatively inexpensive of manufacture, and has a wide range of heat control and of operating speed. Where desirable to screen or sieve the product after drying, this range.
of speed makes possible the attachment of a reel or screen, on the discharge end of the drier, thereby performing the two distinct functions of drying and screening 1n one operation. When the screening attachment is used, the heating pipe is extended through the screen. Moreover, the various operating parts of the drier are accessibly located for purposes of repair or replacement, and the fuel consumption is low. Our arrangement not only secures a uniformly complete drying action, but avoids all danger of contamination of the material being dried, by
the products of combustion. The self-loading feature, moreover, permits the drier to operate with minimum attention.
v OFFICE.
33 and 4-4, respectively of Fig. 2, and
Fig. 5 is a detail view of the internal heating pipe, removed.
Our drier comprises a rotary shell 1 and an internal heating pipe 2 rotating therewith. The shell 1 may be in sections bolted together,.and is rotated on annular tires 4 which are supported upon and spaced from the shell 1 by brackets 5 (Fig. 3). The tires 4 run in ways' l carried by supports 4, the height of the supports preferably being such as to cause the shell to slope downwardly from its intake end towards its discharge end (see Fig. 1). The drive 3 for the shell (Fig.1) may be by sprocket and chain.
The internal heating pipe 2 may be heated in any suitable manner. As here shown the pipe is heated by oil,,and I have indicated at 6 an oil burner of conventional type for heating said pipe. The burner 6 may be supplied from the oil tank 6'. The heating pipe itself is mounted within the drier shell in supports 7 (Fig. 4) which are fastened to the'inner face of said shell and to which the pipe is clamped as indicated at 8.
At its intake end therotary shell 1 is provided with an annular seriesof spaced scoops 9 constituting an automatic feed to pick upthe material to be dried as the shell rotates. Whether mechanical feed or hand feed is used, precaution against spillage of material at intake end may be provided by bending the spaced feed ribs 10 at the receiving end of the shell as indicated at 11 in integral with the pipe.
Fig. 2. The ribs 10 extend longitudinally of the shell and direct thematerial onto the rotating heating pipe 2. The material is temporarily retained in direct contact therewith by a' plurality ofspaced longitudinally extending retaining ribs 12 which are cast The retaining ribs 12 are interrupted between their ends as indicated at 13, Fig. 5, opposite the central pipe support 7, and the shell is-provided with one or more hand holes 14, Fig.2, permitting access to the interior thereof, for the purpose of tightening said pipe support.
- Where it is desired to screenthe material after drying, a reel or screen 15, Fig. 1, may be mounted at the discharge end of the shell 1 and the heating pipe 2 extended through this screen.
Various modifications in the form and construction of our drier may obviously be resorted to within the limits of the appended claims.
\Vhat We therefore claim and desire to secure by LettersPatent is:
1. A drier comprising a rotary shell, 2. screen at the discharge end of said shell, and an internal heating pipe extending through said screen and rotating with saidshell.
2. A drier comprising a rotary shell, a screen at the discharge end of said shell, a self-loading device atthe intake end of said shell, and an internal heating pipe extending through said screen and rotating with said shell.
3. A drier comprising arotary shell and an internal heating pipe rotating therewith, flanged-supports for said pipe fastened to the inner face of said shell, clamps fastening said pipe tosaid supports, a series of longitudinally extending spaced retaining ribs on said "pipe, said ribs interrupted between their ends adjacent a pipe support and said shell being provided with a hand hole adjacent the points of interruption of said ribs to permit access to theinterior of the shell'for the purpose of tightening the pipe support.
In testimony whereof we affix our signatures in presence of two witnesses.
- WILLIAM A. HARTY.
- FRANK W. MOORE.
