SPECIFICATION forming part of Letters Patent No. 642,989, dated February 6, 1900.
Application filed April 27, 1899.
To all whom it may concern.-
Be it known that I, CHARLES H. LANE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Separators, of which the following is a full, clear, and exact description, the accompanying drawings.
My invention relates to an apparatus for separating the lighter from the heavier particles in a drypulverized mass, especially for separating the rock from the mineral in pulverized ore.
The invention consists in the combination of an inclined sieve, onto the upper end of which the pulverized mixture is introduced, means for moving said sieve to cause the mixture to flow down toward the lower end thereof, an inclined chamber inclosing said sieve and into which the material falls from the sieve, and means for causing an air-current to flow through the outer chamber toward and out of its upper end, whereby to carry off the lighter particles.
It also consists in the more specific construction and combinations of parts which are hereinafter described, and set forth in the claims.
. In the drawings, Figure 1 is a side elevation, partly in section, of an apparatus embodying myinvention. Fig. 2 is a plan view of the same. Fig. 3 is a transverse sectional View through the cylindrical sieve-box. Fig. 4 is a perspective view of the means for drawing the material out of the hopper into the upper end of said sieve-box, and Fig. 5 represents three pieces of thescreen-cloth which covers the sieve-box. This view is intended to show that in difierent parts of the box the mesh of the screen-cloth is a different size.
Referring'to the parts by letters, A represents an inclined cylinder which is rotatably mounted in bearings a a. The upper end of Serial No- 714,674. (No model.)
upper end into the hollow casting and thence through the outlet-pipe b and past the fanblower to some suitable delivery-point.
In the lower end of the cylinder A is an internal gear 602, by means of which the cylinder is caused to rotate, as hereinafter specified. Just above this internal gear an inwardly-projecting ring a is secured, the purpose of this ring being to prevent the material in the cylinder from flowing out upon said gear. Just above this ring area plurality of openings a through which the material is designed to be discharged.
Inside the cylinder A, which forms an inclosing chamber therefor, is a second inclined cylinder D, the primary purpose of which is to serve as a sieve to sift the finer particles of the material into the chamber A. The upper end of this cylinder D projects out through a stuliing-box in the upper end of the hollow casting B, and the projecting end of said cylinder is mounted in suitable bearings cl. A shaft d is made fast to the lower end of this cylinder and forms an axial continuation thereof. This shaft project-s out of the lower end of the outer cylinder A and is mounted in a suitable bearing d This shaft and the cylinder to which it is connected may be caused to rotate by means of the bevel-gear d on its end and a meshing beveled gear f, which is attached to the driving-shaft F. A pinion is attached to the shaft d, and it meshes with the internal gear a on the outer cylinder A. By this means the outer cylinder is caused to rotate when the inner cylinder rotates, but at a slower speed.- The open upper end of the cylinder D projects into a hopper H, in which the ma- 7 terial to be acted upon is placed. Some device, preferably a spiral wing J, is secured to the upper end of said cylinder D, and it acts to draw the material out of the hopper into the said cylinder.
The cylinder D for a short distance from its upper end is plain. Then for some distance it is divided into pockets at by internal rings (1 In each pocket are a plurality of balls d The lower end of the cylinder constitutes the sieve-box. It is made of skeleton form and is covered by wire screen or bolting cloth d That section of the sieve which is next to the pockets is finest, and it becomes progressively coarser from this section downward toward the lower end of said cylinder.
The operation of the described mechanism is as follows: The. material drawn into the upper end of the cylinder D moves slowly down the plain part thereof through the action of gravity as the cylinder rotates, and it flows successively into the pockets (i passing over the dividing-rings W. The balls 01 in these pockets act to separate the particles of the material which may have become matted together, and finally the material in powdered form passes over the last ring and then onto the first section of the sieve-that is to say, the screen-covered part of the cylinder. Some of the material will sift through the finest and first sieve-section into the outer chamber formed by the cylinder A. This material is, however, rock-dust for the most part, and this dust is caught up by the air-current caused by the fan-blower and carried out through the upper end of the chamber A and through the outlet-pipe. When the material on the first sieve-section passes onto the next section, the material which passes through is coarser and contains some flakes of metal. The rock-dust in the material as it falls from the sieve is sucked out by the fan-blower, while the metal flakes fall onto the bottom of the cylinder A. This action is repeated from one sieve-section to another until the material which passes over the last section of the screen fabric is substantially pure metal, and this falls out through the holes (1 in the sieve-cylinder into the cylinder A. The material which settles in the cylinder A consists almost entirely of flakes of metal, which as the said cylinder rotates slide by gravity toward the lower end of said cylinder and out through the holes a therein.
Having described my invention, 1 claim- 1. In a separator for separating flake metal and pulverized rock from mixtures of the same, the combination of an inclined rotary cylinder, and means for forcing an air-blast through the same, and out of its upper end,
with a rotary cylinder inside of the first, internal rings in said cylinder near its upper end whereby it is divided into pockets, balls in said pockets, and screens which form a part of the wall of said cylinder below said pockets, substantially as and for the purpose specified.
2. In a separator for separating flake metal and pulverized rock from mixtures of the same, the combination of an inclined rotary cylinder, and means for forcing an air-blast through the same, and out of its upper end, with an inclosed rotary cylinder inside of the first, internal rings in said cylinder near its upper end whereby it is divided into pockets, annular sections of screen materials secured upon and forming a part of the walls of said cylinder below said pockets, each screen-section being coarser than the section above, substantially as and for the purpose specified.
3. In an air-separator for separating flake metal from admixtures thereof with pulverized rock, the combination of an inclined rotary cylinder, a closed hollow bearing for the open upper end thereof, a suitable bearing for the lower part of said cylinder, a pipe connected with the hollow bearing and a fan in said pipe whereby an air-blast may be drawn through said cylinder and out of its upper end, with an inclined rotary cylinder within the first cylinder, and projecting through said hollow bearing, a shaft secured to the lower end of the inner cylinder as an axial extension thereof, bearings for said shaft and for the upper end of said cylinder, a hopper into which the upper end of said inner cylinder projects, a spiral feeding device on said end and screens which cover and form a part of the wall of the lower part of the inner cylinder, substantially as and for the purpose specified.
i. The combination of an inclined rotary cylinder, a closed hollow bearing for the upper end thereof, a suitable bearing for the lower part of said cylinder, a pipe connected with the hollow bearing, and a fan in said pipe whereby an air-blast is drawn through said cylinder and out of its upper end, with an inclined rotary cylinder within the first cylinder, and projecting out through said hollow bearing, suitable bearings for said inner cylinder, internal rings dividing the same into pockets, balls in said pockets, screens covering and forming a part of the wall of said cylinder below said'pockets, a hopper containing material to be acted upon in which the upper end of the inner cylinder pro jects, and means for feeding material from said hopper into the upper end of said cylinder, substantially as and for the purpose specified.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
