APPARATUS FOR OXIDIZING AND DESULPHURIZING ORES.
SPECIFICATION forming part of Letters Patent No. 440,469, dated November 11, 1890.
Application filed August 2, 1890- $eria1llo. 360,742- (No model.)
To aZZ whom it may concern:
Be it known that I, EDWIN M. CLARK, of Butte City, in the county of Silver Bow and State of Montana, have invented a new and Improved Apparatus for Oxidizing and Desulphurizing Ores, of which the following is a full, clear, and exact description.
In the reduction of ores containing any considerable percentage of sulphur it is first necessary to desulphurize the ore. This is usually done by roasting the ore by a suiiicient heat and for a sufficient time to consume or destroy the sulphur.
The object of my invention is to improve the construction of the apparatus for accomplishing this result in a short time and at little expense, for which I filed an application for Letters l atent of the United States April 25,1890, serially numbered 349,460, and which application was allowed July 2, 1890.
' My invention consists, chiefly, in the manner in which the water-jacket is applied to the air-pipe in the furnace and in the means for supporting the water-jacket and connecting it with the air-pipe. This construction will be hereinafter fully described, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a broken vertical longitudinal section of the apparatus as applied to an ordinary rotary calcining-furnace. broken vertical cross section through the dust-flue, showing a modified form of the apparatus. Fig. 3 is a sectional plan of the same on the line 3 3 of Fig. 2. Fig. 4 is a broken vertical longitudinal section of another modification of the apparatus with the furnace removed, and Fig. 5 is a transverse section through the air-pipe and water-jacket on the line 5 5 of Fig. 4.
In the accompanying drawings, A is an ordinary Bruckner furnace, which rests upon pulleys or gears and is rotated in a manner well known in the art, and which needs no detailed description, as the furnace forms no part of my invention.
The furnaceAis provided at each end with Fig. 2 is a central openings B, aligning with the flanges E and with the openings E and F through the fire-box wall and flue-wall, respectively. An air-pipe C runs centrally through the furnace, terminating near one end thereof and having at its end a suitable cap C, the other end of the air-pipe being connected with an ordinary blower, so that air may be forced through the same to the furnace.
As the air-pipe would quickly become redhot from the heat in the furnace, it is inclosed by a water-jacket D, which extends entirely through the furnace, one end being provided with a cap D and resting on the fire-box wall E and the other extending through both walls F and F of the fiuef. A water-supply pipe G enters the water-jacket near the fire-box end thereof, said water-supply pipe passing through the flange E and the opposite end of the water-jacket is provided with a coupling D and opening from the upper side of the coupling is an overflow-pipe H. It is very important that the overflow-pipe should open from the top of the water jacket, as the water in the upper part of the water-jacket is hotter than in the lower part, and by allowing it to flow out from the top the water-jacket is prevented from warping.
A reducer O is screwed into the outer end of the coupling D and the small end of the reducer fits closely upon the air-pipe C. A packing c is placed next the reducer, and a nut c is screwed firmly upon the air-pipe and against the packing, thereby holding the pack ing and the reducer in place. Opening from the air-pipe, through the water-jacket and into the furnace, are tapering jets e, which open through the bottom and sides of the water-jacket, as shown and claimed in my former application above referred to.
The water-pipe c is held in a fixed position in relation to the water-jacket D by the bolts d, which are preferably arranged in series of three and which are screwed through the water jacket and into the air-pipe, the inner ends d of the bolts being tapered, as shown in Fig. 5, and fitting tapering holes in the airpipe, thereby acting as plugs and holding the air-pipe and water-jacket in a fixed position in relation to each other. The arrangement of the bolts and air-jets is the same in the 'various modifications, the difference between the modifications being in the arrangement of the pipes. The form shown in Fig. 1 is preferable, as there are no elbows in the pipes and the Water and air flow freely through the same.
As shown in Figs. 2 and 3, the Water-pipe C and water-jacket B terminate in the flue f, and are provided with elbow-couplings J and K, respectively, from which extensions 0 and D extend through a side wall of the flue f, and the outer ends of thepipes are provided with a coupling and reducer, as already described.
As shown in Fig. 4, the Water and air are both admitted at the end next the fire-box, the ends of the air-pipe O and water-jacket B being supported in the flange E of the metal Wall E of the fire-box. The air-pipe C is provided with an elbow-coupling J at the end next the fire-box, andis supplied from a pipe 0", opening into the air-pipe through the flange E the opposite end of the pipe 0 being provided with a cap 0'. The end of the water-jacket next the fire-box is also pro-1 vided with a suitable coupling K, and open ing through the lower side of the coupling is a Water-supply pipe G, which passes through the bottom of the flange E The opposite end of the water-jacket extends through both walls of the fluef and 'isprovided witha cap D from the upper portion of which opens an overflow-pipe H, which permits the hot Water to escape from the upper portion of the water-jacket, as in the other forms described above.
The capacity of the combined air-jets e should be greater than that of the air-pipe C, so that When air is forced through the pipe under great pressure it will not pass through the jets with suificient force to scatter the ore.
Having thus fully described my invention, I claim as new and desire to secure by Let ters Patent 1. In an apparatus of the character described, the combination, With a water-jacket extending through the furnace, of an air-pipe inclosed by the water-jacket, said air-pipe having one end stopped, as shown, and having jets opening through the water-jacket, and bolts having tapering points, said bolts extending through the waterq'acket and into the air-pipe, substantially as shown and .described.
2. An apparatus of the characterdescribed, comprising a revoluble furnace, having end openings therein, a water-jacket extending through the furnace having both ends stopped, a water-supply pipe opening into one end of the water-jacket, a discharge-pipe opening from the upper-portion of the waterjacket at the opposite end,an air-pipe inclosed by the water-jacket and stopped at one end, jets projecting from the air-pipe and through the Water-jacket, and bolts having tapering points, said bolts extending through the water-jacket and into the air-pipe, substantially as described.
