ARTHUR E. PEW, JR, OF BRYN MAWR, PENNSYLVANIA, ASSIGNOR TO SUN OIL COM- PANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
MINERAL-OIL STILL.
Original application filed June 19, 1925,
In an application filed by me June 19, 1925, Serial No. 38,184, of which this application is a division, I set forth an apparatus for the continuous distillation of oil under a high vacuum. Included in the apparatus is a series of stills. The oil in each of these stills is under a high vacuum. Consequently, it is essential that the stills should be so constructed that there will be no danger of their collapse under external atmospheric pressure. The present invention comprises a still of this character. A preferred construction is shown in the accompanying drawings, in which- Fig. 1 is a longitudinal section through the still.
Figs. 2 and 3 are cross-sections on the lines 22 and 3-3 respectively of Fig. 1.
The cylindrical body a of the still is provided with end heads 6 permanently welded thereto.
At intervals along the length of the still, annular deckbeams c are secured to the internal wall by welding the same thereto at intervals as, :12, etc. Two longitudinally ex tending channel irons d, al connect the end heads. Diametrically extending channel irons e are secured centrally between the two channels 03, d and at opposite ends to the deck beams c. Radially extending pipe struts f, f, f are secured at their inner ends to channels cl, al and at their outer ends to deck-beams 0. In the preferred construction, two series of struts 7, f are in two radial planes extending longitudinally of and obliquely to channels d, (Z and are secured to channel al while the struts f of a third series are in a radial plane extending longitudinally of and perpendicularl to channels d, d and are secured to the c annel d.
The deck-beams c are notched at 3/ to form a diainage channel along the bottom of the tan The internal reinforcements above described are adapted to the reception within the still of a longitudinally extending inclined vaporizing pan, which, in my invention, is utilized when the still is adapted for use in continuous distillation. This pan, however, forms no part of the present invention and is not herein shown. Nor, for the same reason, do I show means for admitting oil and discharging oil and vapors and for rendering the stall air tight,
Serial No. 38,184. Divided and this application filed February 27,
1926. Serial No. 91,044.
In addition to the structural features hereinbefore described, the still may be provided with a partition 9 having radial stiffening ribs k and an opening adapted to be closed by a cover plate 5. In a series of stills, such a partition would ordinarily be provided only in the last still (the tar tank) of the series.
I claim:
1. A still comprising a cylinder, a longitudinal reinforcement connecting its end walls, reinforcing deck beams extending circumferentially and secured to the inner wall of the cylinder, and transverse reinforcing members connecting the longitudinal reinforcement and the deck beams.
2. A still comprising a cylinder, a pair of longitudinally extending bars connecting the end walls of the cylinder, transverse diametric bars whose central portions extend between the longitudinal bars, radial bars each of whose inner ends engage one of the longitudinal bars, andmeans connectin the opposite ends of the diametric bars an the outer ends of the, radial bars with the inner wall of the cylinder.
3. A still comprising a cylinder, reinforcing deck, beams extending circumferentially and secured to the inner wall of the cylinder, a longitudinally extending angle bar structure connecting the end walls of the cylinder, and transverse members'comprising angle bars and pipe struts connecting the longitudinal angle bar structure with the deck beams.
