UNITED STAT HYDRAULIC AI'PABATUS FOB law To all whom it may concern:
Be it knownthat I, GEORGES Ln onUX, a citizen of the French Republic, residing at 63 Avenue des Champs Elysees, Paris,,France, have invented new and useful Im rovements in Hydraulic A paratus for lassifying Heterogeneous ranulous Materials, of which the following is the specification.
The present invention relates to an improved hydraulic apparatus for classifying heterogeneous granu'lous' materials and has for-its primary object to improve the classification and to increase the output of the apparatus. r
The accompanying drawingillustrates by way of example only and diagrammatically,
a form of construction of the invention.
Fig. 1 is an elevation of the apparatus.
Fig. 2 is an elevation in partial section, on enlarged scale, of the part of Fig. 1 designated by D.
Fig. 3 is an elevation with partial section, on enlarged scale, of the part of Fig. 1 designated by E.
Fig. 4 is an elevation with partial section, on enlarged scale, of the part of Fig. l designated by F.
Fig. 5 is a section on A-A of Fig. 3.
Fig. 6 is a section on BB of Fig. 3. v
Fig. '7 is a section on CC of Fig. 4.
In this example, the raw materialsto be separated are fed through the trough l and they are drawn in the trough 2 by means of a stream of water the intensity of which is adjustable by the cock 3.
The trough 5 has a curved bottom (Fig.2) and is slightly inclined on-the horizontal. Under-the influence ofthe-stream of water, the materials are classifiedin horizontal layers by order of densities, the light materials being situated at the upper part of. the bed, and the heavy materials at. the lower'part of the bed. At its lower end, the trough 2 is secured on an a'scendingQwaterstream apparatus 5; this apparatus is essentially constituted by a trough 5"? connected to the trough 2 and in which open a series of vertical columns5l, 5, 5 Figs. 2' and 6 communicating on the-other hand at their lower part with the columns 5", 5 5 through openings such as 5*. Walls such as 5 close the lower part of the columns 5 .5, 5 whilst the columns 5 5, 5, open in the cylindrical chamber 5 in which rotatesa distributor 5,
actuated for instance by the pulley 5 PATENT" OFFICE.

5). The cross section of this distributor is such that the columns 5*, 5, 5, are never directly in relation with the atmosphere. The columns 5, 5 5 are connected to water inlet pipe-lines, such as 6, each provided with a cock 7, which permits to adjust the pressure of the water in each of the columns. Above the outlet point of the columns 5*, 5, 5 in the trough 5 is arranged a plate 5, secured to the cross bar 5 against which slides a damper 4. The plate 5 is perforated "on a portion of its length in the shape of a sieve and under this perforated part is arranged another trough 5 in cornmunica tion with awater exhaustpipe line 5.
In order to make the damper 4 adjustable, the latter is pivoted at 4 on a screw threaded rod 4", which passes through the bore of a support 4 and is secured by means of nuts 4 and 4 For raising the damper 4, it suffices to unscrew the nut 4 and toscrew the nut 4 reversely, for lowering the damper, y
damper 4. These materials, when arriving in front of the outlet point of the' columns 5", 5 5 would fall vertically in these columns, if they did not encounter the antagonistic verticalwater stream. Owing to these currents, alone the materials of the greatest density can fall in these columns; the materials of lesser density arebrought back by the vertical stream. of water towards the orifice 5. The materials which fall to the bottom of the columns 5 5", 5 are evacuated through the rotating. distributor 5. For avoiding the wedging actions which might occur, paddles 5 arerigidly secured on the axis 5 which projects to the exterior and on which is rigidly secured an arm 5; a spring 5 aotsbetw een this arm and a boss integral with the frame 5, in such a manner that the paddle 5 may be always pressed against the distributor- 5 but it is obvious that, when a stone wedges between this distributor 5? and the paddle 5 the latter rotates for allowing the stone to escape. I V
i The lighter materials pass on the plate15 and Water escapes, through the holes of the Ill perforated .part into the trough and in the pipe line 5 This evacuation-bf water compensates the supplementary admission of water through the columns 5*, 5?, 5.
The arrangement of the plate 5'" above "water woulddestroy'the previous olassifica- :tion effected by the inclined trough;
To the trough 5 is connected a portion of the inclined-trough 8, the'end'of which is partially closed'bya partitionfi A darn {per QSliCl'BS'QlOH-g this partition 8 =it is p'iv ot'ed at 9 on a rod 9 "which passes through a boreof a support 9securedon the'trough 5' The-screw threaded rod 9* is immobilizechbynuts i -and 9 It w'ill'be seen that this arrangement is'quite similar to that of the damper 4. .On the otherhand, a plate 8 formsan ezitension of the plate 5; the
dightmaterialshaving passed on this plate, and those which have been brought back by the vertical stream of water under the plate 8 meet after this plate and pass'underthe =-dam-pe'r,-9 in the inclined trough 10 which is in thetrain cram trough 8. In this trough 10, "as previously in the trough 2, is formed a bed 'of materials roughly classified by order of densities. In the 'tra inofthe 't-rou'gh 10 might therefore be arranged an apparatus similar to -5 (but the vertical streams --of water would have zpressures less high) for "completing *the classification, and so on; but "a classification not "sufiicientl-y iprecise of the :materials would thus be obtained, which materials have, at the end" of the treatment,-- densities somewhatnea'r each other; It -is then necessary to use-a me chanical shaking classifying: apparatus constituted in the following manner:
The=trough 10*opens abo've asplate 11'-act 'ing as a sieve, constituted for instance by a wire :gau'z'e or a perforated "sheet iron ;plate. This plate forms the bottom of a box having 'three 'si-des 11 1 1', 1-1,'(Fi:gs.'tand 7) the 'fourth side 1 1 being'open. Onthi's side-is arranged a :plate acting "as a dam 11', in front-of whiolfiis-an adj-ustabledamper 12, quite similar 'to th'e'dampe'rs stand 9 and *whioh consequently, it is not necessary to desc'ribe a-ny -further. The sides l'l and 11 each carry trunnions 11 and =1 1 't0 which are pivotally connected the big ends ofcon necking rods ligand '14. These connecting rods are rigidlysecured on shafts 15 and 16, supported by bearings such as 1?, integral with the outer casing 18. This casing receives at its lower part a hopper 19, a branch 19 of'whi'c'his connected to an exhaust pipe line-2O throughthe-medium of a valve 21.
On-the other hand, on the shafts 15 and 16,
are rigidly secured arms 22 and 23 support ingcounterweights 524: and 25.
The side 11 is provided with a fork piece 11 on Which' is pivoted,"by means of an axis -'-26,'a'connectinga-od 27. 'O'n th'eother hand, a "connecting rod 28 is :pivotally connected througlrtheaxis 29011 afork'piece 30, which is secured on the Wall "18 of the casing.
against a cam 'rigidlysecured onthe shaft- 36; this shaft is 'cau's'ed to rotate through the pulley 37 and the belt 38 for {instance 'It isobviousLtlrat the rotation of the s'haft S6 has 'for'efi'eot to impart shocks or vibrations to the plate 11, so as to' produce the classificationofthe layer ofanaterials'by. or-
d'er ofdensities.
For facilitating this classification streams of water "are caused to en-ter through the radially' pe'rforatetl tubes 89and 40, the admission ii'i. e"a"c-h of these tubes being controlled by acoeksuch as 41. The lightest materials are "carried over the, damper 12 and the plate 11" and' the denser materials epass und-er this plate. Of course, the very fine materials pass through 'the holes of the sieve, they are eliminated through the "sluice-val-Ve-Ql. In general, these *fine materials are'of great density;- in the case of separation of coal, "these fine "materials-are :espeoially composed of pyrites.
in the train *of the shaking =classifying app ar-atus described, arran-ged an ascending water stream separation apparatus, the constitution and method of separation of which a'te entirely identical to those described' for the'apparatus'fi; it is the reason why it has not beenconsidered necessary to repeat this description. '-In the drawing "have "been simply indicated for the ascending water stream -a paratus not described the Samoa-timbers of reference as for the apparatuses 5 and 9, these numbers of referericebeing however provided with indicia. The "very rlight materials which are not eliminated are then evacuated through the final trough 39, the outflow being controlled by the damper 9.
