ALBERT F. ANDREWS, CE AVON, CONNECTICUT, ASSIGNOR To THE CLIMAX EUs COMPANY, OF SAME PLACE.
APPARATUS FOR OXlDlZlNG OILS AND TAR.
SPECIFICATION Application filed February 18, 1887. Serial No. 29 ,070.
To aZZ whom, it may concern:
Be it known that I, ALBERT .F. ANDREWS,
a citizen ofthe United States,'residing at Avon,
in the county of Hartford and State of Oonuecticut, have invented an Improved Process of and Apparatus for Concentrating and Oxidizing Tar, Drying Oils, and Similar Liquids or Semi-Liquids, of which the following is a specification.
My invention consists in boiling the tar in a closed kettle, the tar being kept in continual circulation and constantly exposed to a strong current of air blown through it or upon its surface.
To carry out this process I make use of a kettle covered at the top and heated in any convenientmanner,eitherinternallyorexternally. I place a vertical shaft in this kettle, stepped into a support at the bottom and supported by bearings at the top. A pulley is attached at the top of the shaft to rotate it and a series of paddles at the bottom. I inclose this shaft in a vertical inclosure or tube secured to the bottom of. the kettle and rising to or slightly above 2 the level of the tar. This tube is provided with large openings at the bottom, and a series of small openings or holes encircle it in tiers to the top. Over this tube I place a second or telescopic tube, open at the bottom, but closed at the top, and carrying a pipe through which a blast of air can be blown.
In the drawing, (which is a vertical section through pipe 0,) A is the kettle having a cover, B, which also acts as asupport for the 5 rotating vertical shaft G, resting in a step, (Z,
at the bottom of the kettle and in the upper bearing, d". O is an air-blast pipe;I, an air and gas escape opening. This shaft D carries at its lower end the agitating-paddles E, and is a e driven by means of a pulley, F, at the top. A
tube, 1), open at the top and pierced with numerous holes, 9, from the upper level of the paddles to its top, is secured to the bottom of the kettle. Larger openings, 5 aremade at the 5 bottom for the escape of the liquid current drawn in through the holes 9 by the action of the paddles. Over G a tube, H, closed at the top, slides telescopically, carrying with it the air-blast pipe 0, which can either slide telforming part of Letters Patent No. 366,991, dated July 19,1887.
(No model.)
escopically or be attached by a flexible coir 5o nection.
T is the tar or similar liquid to be evaporated. The arrows indicate the direction, of the flow of air and liquid.
The paddles are to be set quite near to the bottom of the kettle, and are of any required size. Eight inch blades will handle seven hundred gallons per minute when running at six hundred turns per minute.
The circular case or tube should be of nearly 6 the same diameter as the paddles. This case may extend above the surface of the tar. At its upper end this case should be thickly perforated with holes from a quarter of an inch to one and oue-half inch in diameter. A telescopic tube, H, a little larger than the stationary perforated tube, should surround this, so that by moving up and down alarger or smaller number of the holes will be opened, as may be desired.
The operation of this device, which is very simple, is as follows: The shaft is rotated, forcing the tar downward to the heated bottom of the kettle, creating a suction in the perforated case or tube and drawing in the tar through 7 the numerous holes. The air-blast is turned on, and the jets of tar mixed with the air come in contact with the paddles, which comminutes the tar and brings it into intimate mixture with the air in a very fine state of division. The tar, mixed with air, is thrown to the bottom of the kettlc,and, receiving additional heat, passes upward along the inside of the kettle to the surface ofthe tar, where the air and gases escape, and the tar moves to the center again to go through the same process. The opera tion is continuous and rapid, more so than any that I am acquainted with.
The entire contents of the kettle can every minute be mixed with a fresh volume of air. The telescopic tubes can be adjusted according to the amount of tar, and the blast of air can be increased or diminished, as may be desired.
W'hilethis device and process are primarily 5 designed for the evaporation and condensation of tar, it may also be used to oxidize linseedoil, or for the evaporation of sugarsirups,
either in the vacuum-pan or outside and in- 'dependent ofit, in the latter case the airrblast being heated to from 120 to 150 Fahrenheit.
In any case where rapid evaporation is desirable it is-preferable to use a hot-air blast.
The paddles may be of any number and of any shape, plane or curved.
WVhile the use of the cover to the kettle is important, it may be omitted when the liquid does not spatter too much.
Having now fully described my invention, what I claim, and desire to secure byLetters Patent-,is-
