RETORT FOR TREATING ORES.
SPECIFICATION forming part of Letters Patent N0. 669,411, dated March 5, 1901.
I Application iiled February Z1, 1900. Serial No. 6,070. KNO model.)
To all whom it may concern:
Be it known that I, FRANKLIN GUITERMAN, a citizen of the United States, residing at Denver, iu the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Retorts for Treating Ores; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improved means or apparatus for carrying on the treatment of ores for the recovery of the contained metal therefrom, especially those ores of Zinc which are more or less associated with the ores of other metals, by a method of reduction with redncing-gases-such as carbonic-oxid, hydrogen, hydrocarbon gases, water-gas, coal or producer gas, natural gas, &c.-in which the reducing agent is brought into intimate contact with the divided or granular ore under pressure in the presence of heat, but without contact of iiame, atmospheric air, or combustion agents, with the ore under treatment, by which means the yield is increased, impurities excluded from the product, and the recovery of valuable metals from the residue is made practicable.
My improvements consist in the details of mechanism described and claimed herein and illustrated in the accompanying drawings, in which- Figure l is a central vertical section of the apparatus. Fig. 2 is a horizontal section thereof, taken on line 2 2 of Fig. l. Fig. 3 is a detail view of the sleeve on the conduits for delivering ore.
In the drawings, 23 is a vertical retort-cylinder of dimensions suitable for the work required, made of refractory materials, such as fire-clay, which may be made in a series of segmental rings superimposed to the required height and properly secured. Outside of this cylinder is a jacket 26, of brickwork, located at a sufficient distance from the retort-cylinder all around to provide annular passages for the circulation of the hot gases or products of combustion by which the retort is heated through the walls thereof from the outside. Said jacket is lined with fire-brick or other refractory material 25 and is stayed or bound with hoops of steel a where required. The whole structure rests on an annular' plate or casting b, which is sustained by I-beams 27, resting on supporting-columns 28, four or more in number.
c d e are domed arches located at proper intervals, which divide the annular space between the two cylindrical walls horizontally into annular cham bers or due-spaces 3 4 5 6 7 8, there being an opening 9 upward through the arch or vault of each annular chamber at one point for the products of combustion to pass through from chamber to chamber, abarrierwall u being provided in each chamber, the openings being so located on alternate sides of the barrier-Wall as not to come over each other, but to cause the flame to make the circuit of each chamber before nding an outlet into the chamberabove. Aspirally-arranged passage between the two parallel walls made by a gradually-ascending partition in the annular spacing would be the full equivalent of the series of chambers above described, but would be more difficult of construction. The products of combustion linally escape from the uppermost chamber by passage t and a iiue leading to a chimney or stack, the due shown being a downtake-lue y, terminating in a horizontal passage leading to said chimney. A fire-place or combustion-chamber is shown atl, communicating by-a throat or flue 2 with the lowermost chamber of the series. The fuel burned in this chamber is preferably producer-gas for this purpose, but may be any combustible of suitable character.
l2 is a vertical pipe centrally located and suspended Within the retort-cylinder, extending nearly or quite to the bottom thereof. Its purpose is to conduct and distribute the reducing gas to the ore under treatment, which gas is admitted .through a pipe ll at the top, leading from a source of supply under pressure. On and surrounding said pipe are fixed inclinedaprons or cone-shaped baffle-plates 14. 16 18 at suitable intervals, held apart and spaced by distance pieces or tubes f g h, which, with said bafe-plates or aprons, may be made in halves for convenience of removal and renewal, or they may be strung on the pipe by making the flanges at the top re- IOO movable. A fiange or oiset p at the bottom of the pipe 12 sustains the series. These baieplates and distance-tubes may be iliade of nre-clay, as indicated in the drawings, or of metal or other suitable material. Intermediately of the baffle-plates or aprons already described are other inclined aprons or baffleplates 15 17, made of similar material, located against the wall of the retort-cylinder and suitably supported thereby. In the drawings they are shown supported by annular offsets formed on the rings composing the retort-cylinder.
j are apertures through the walls of the central pipe and distance-pieces, beneath the central baliie-plates, for the passage of the reducing-gas.
10 is a double hopper communicating with the interior of the retort on opposite sides of the central pipe by conduits 13 13, which pass gas-tight through the top plate 22. Said hopper may be annular, if desired, and supplied with more than two conduits, placed at regular intervals, t-he object of these conduits being to feed the ore in regulated quantities to the inner cavity of the retort surrounding the central gas-pipe. On said conduits I have arranged movable sleeves r r, operated by rods S s, passing up through the conduits and through the hopper, having handles on the upper ends, by whichmeans the said conduits may he lengthened or shortened at pleasure, thereby enabling the height of the column of ore in the retort to be regulated. The rods s s may be attached to the sleeves r by means of a spider q or cross-bar affixed to the sleeve at its lower extremity, as shown in Fig. 3, or in any other Workmanlike manner. At the top of the series of annular chambers the two walls are merged into a single wall w, resting on the retort-wall and the topmost domed arch, and in this wall is a perforation supplied with a pipe 32, through which the reducing-gas escapes from the retort after doing its work. Said pipe terminates in a watertrap 30, having' a water seal 3l, an exit-pipe 33, and a water-cock 7c.
The lower part of the retort is/closed by a truste-conical chute 19, preferably of castiron,with an opening o in the bottom, in which chute are lateral apertures z, closed by removable covers m, said apertures serving for the introduction of stirring-bars should the material become agglomerated or adhere. Beneath this chute is a cone or hopper 20, supported by I-beams 29, resting either on pedestals of masonry, as at the right, or on channel-bars and brackets sustained by the colnmns 28, as at n. The lower opening of the hopper 2O is closed by the reciprocating shoe 2l, of cast metal, which being moved by suitable power back and forth at the requisite speed, which can be regulated to suit circumstances, permits the reduced ore to fall intermittently into a car or carrier placed beneath.
I claim and desire to secure by Letters Patent- 1.
