0. B. PEGK. METHOD OF HANDLING AND DELIVERING SLAG.
Patented Ju1y Z9 UNITED STATES ORRIN B. PECK, OF CHICAGO, ILLINOIS, ASSIGNOR TO SAME PLACE.
PATENT OFFICE.
MELINDA PECK, OF
METHOD OF HANDLING AND DELIVERING SLAG.
SPECIFICATION forming part of Letters Patent No. 433,136, dated July 29, 1890.
Application filed March 3, 1890' T aZZ whom it may concern.-
Be it known that I, ORRIN B. Pack, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois,'have invented a new and useful method of I Iandling and Delivering Smelting-Furnace Slag, of which the following is a specification.
The object of my invention is to provide for granulating the slag of smelting-furnaces 1c. and pumping the same out or away after it is granulated; and the invention consists in the method hereinafter described and claimed.
The accompanying drawing shows in side elevation, partly in section, an apparatus adapted to carry out my process of granulating and pumping away smeltin g-furnace slag.
In the drawing, V is a vessel by means of which the molten slag is granulated; A, a shaft by which the vessel is supported and rotated; I3, journal-boxing; C, a centrifugal or force pump; D, a pipe or conduit for introducing water; E, a curb forming a chamber around the slag-vessel; F, a passage between the chamber and pump, and II a spout or con duit for carrying away the slag and water from the pump.
Various forms of mechanism may be used for carrying out my process, one of which I have shown in the drawing. This apparatus 0 consists, essentially, of acentrifugal machine having a revolving vessel or receptacle adapted to receive the molten slag or product to be granulated and to discharge the same in small or divided particles; a pipe or conduit 3 5 for introducing water and spraying it on the molten slag as the slag is discharged in particles from the receiving vessel or receptacle;
Serial No. 34.2,425. (No modeli) finely-divided particles which in cooling are solidified in a granulated state. Most of the separated particles, thrown off or out from the receptacle are of a spherical form, so that when cooled most of the slag is in little round 5 5 particles, something like shot. This enables them to be pumped out with the least possible wear or injury to the machinery.
I prefer to divide or separate the molten slag into particles by a centrifugal machine, or by subjecting the slag to the action of centrifugal force; but it may be separated in other ways.
I prefer to introduce the water used for cooling the slag in a spray; but it may be introduced in any OtllGl'COl'lVGlllGllt way. In some cases, also, it may be found advisable to introduce steam in place of or in addition to water, for the purpose of cooling or hardening the divided slag. My object in thus using water is to quicken the solidifying of the particles of molten slag to keep them from again uniting or sticking together in mass and to enable them to be readily carried or pumped away.
I prefer to employ a centrifugal pump for forcing or conducting away the water and granulated slag; but any other suitable pump capable of doing the work may be used for this purpose. The pipe or spout for carrying 8 away the slag and water from the pump may be made in any form and extended to any distance desired; but it will generally be found advisable to extend it to the point of final deposit for the slag. I
As the essential feature of my invention consists in granulating and watering the slag and then pumping it away while in a granulated state, it will of course be understood that I intend this application to be generic, and that I do not limit myself to the special forms or steps above described.
I claim- 1. The method of carrying away smelting, furnace slag, which consists in finely dividing it' while in a molten state, mixing it with water, and pumping it out to a place of deposit, substantially as described.
2. The method of carrying away smeltingfurnace slag, which consists in finely dividing The molten slag, mixing it with Water while ticles to the actiouof a cooling medium, and finely divided, and pumping the particles and then pumping them out to a place of deposit,
Water away, substantially as described. substantially as described.
3. The method of carrying away smelting- ORRIN B. PEOK. 5 furnace slag, which consists in finely dividing \Vitnesses:
it while in a molten state by the action of GEORGE S. PAYSON, centrifugal force, subjecting the divided par- SAMUEL E. HIBBEN.
