QPECIFICATION forming part of Letters Patent No. 735,855, dated August 11, 1903. Application filed July 8, 1902- S erial No. 1l4,794. (No model.)
To all whom it may concern:
Be it'known that I, FRANooIs BLANo, a citizen of the Republic of France, residing at Chambon, Loire, in the Republic of France,
have invented certain new and'useful 1111-.
tationfor instance, the motion which takes place in a centrifugal pump and in certain kinds of turbines--t.wo more or less solid particles of difierent weight contained in the liq uid will travel through the interior of the liquid in two different paths or trajectories, resulting from the combined action of centrifu gal force and the carrying-away force.
The object of my invention is to effect the separation of the trajectories, and conse-i quently to establish a method of classifying by weight of the solid particles previously mixed with a liquid which traverses the apparatus. In this way it is possible to obtain and enrich the mixture of solid particles by isolating, for instance, in the treatment of coal, all the slatey parts, andfor metalliferous sand all the particles of a weight heavier than a determined weight.
The accompanying drawings represent schematically two apparatus based on the principle above mentioned, with the aid of which the invention can be carried out.
.Figure 1 is a device for effecting the separation of the particles treated by the action of centrifugal force, the current moving away from the axis of rotation. Fig. 1 is an elevation of the construction seen in Fig. 1, partly broken away and being partly in section. Fig. 2 is a form of turbine producing the same result, the current being drawn inward to the axis of rotation. Fig. 2 is a sectional view on the lineA B of Fig. 1
In Fig. 1 the shaded part represents only one of the blades of the turbine, in which the separation of the paths of travel is obtained in the following manner: On the blades a of the device-for instance, of a centrifugal pump-a projection 19 is arranged, forming with the direction of the current an angle which can vary according to the nature of the mixtures to be treated. With a determined rate of discharge the speed of rotation is such as to allow particles of the same diameter and of. a weight greater than the determined weight to enter the hollow space'beyond the projection 19, from whence a chanapparatus indicated in Fig. lcannot be used in such cases. The paths of travel of materials of different density cannot be simply separated in the interior of the device, and recourse must be had to another device or form of construction.
As indicated in Fig. 2, the materials to be classified suspended in a liquid current enter through an inlet d a casing in which a wheel f, with bent arms or blades or inclined channels, rotates in the direction of the arrow f, between which blades the liquid is obliged to pass before escaping through the center passage o. The solid particles carried along by the current, which enters under pressure, can .only traverse the Wheel 1" in the direction of the arrows g it so far as the traveling force of the current is sufficient to overcome the efiect of the centrifugal force, which tends to surrounding the movable wheel 0' without being able to traverse it; They can be remov'ed in various ways. The simplest consists in putting the space surrounding the movable wheel in communication through an opening c with a deposit-chamber outside the apparatus.
The apparatus shown in Fig. 2 can be considered as supplementary to the firstdescribed apparatus, Fig. 1, in so far as it serves to complete the classifying of materials hav- 1 the inner surface of each blade and'at a deing already passed through to the latter aptermined angle thereto, a hollow recess beparatus. The apparatus shown in Fig. 2 has yond said projection in connection with ade- I; in this case adouble objeotto efiect a more posit-chain ber, substantially as set forth.
