EXTRACTION VESSEL.
Specification of Letters Patent.
1 Application filed May 31, 1905. Serial No. 263,020-
To aZZ whom it may concern.-
Be it known that I, CLAnnNcE M; CHAM- BERLAIN, a citizen of the United States, re-
and ate of South Dakota, have invented certain new and useful Improvements'in Extraction Vessels, of which the following is a specification.
This inventionis an extraction vessel designed particularly for the treatment of crushed ores, slimes, or other metal-bearing material. v
A preferred embodiment of the invention is. shown in the accompanying drawings, wherein Figure 1 is a perspective view of the vessel with the filter trays and cover removed. Fig.
2 is a transverse section of the vessel, on an.
enlairged scale, parts being broken'away and the ter-trayss above the filterbed. Fig. 4 is a vertical section of the inlet end of a tray. Fig. 5is a perspective view of a modification. Fig. 6 is .a perspective view, on an enlarged scale, of a form of cover for the fillin end; and Fi 7 is a partial vertical section s owing amo ified construction of tray. I
Referring to the drawings, 1 indicates a cylindrical air-tight tank or vessel capable of withstanding internal pressure. The vessel is mounted upon trunnlons 2 in suitable'be ar-f ings and is partially encircled by a reinforcing" strap or band 3. The trunnions are preferably located at points between the center ofthe vessel and the discharge end in order that the horizontal positionmay be stable, A. suitable positively-actin 'dev1ce, here 1ndi-' cated as a pneumatic li t 4, is provided for inclining the tank as. required. In the form illustrated in Figs. 1 'to 4 a casting 5, secured to the discharge end of the vessel, afiords an unobstructed aperture or discharge-gate eX tending across the vessel through which the filter-trays may be inserted and removed. A packing 6 is provided on the face of the casting 5, and a similar packlng may be provided on the inner face of the cover 7. Rods 8, which preferably pass longitudinally 'th'roughthe-tank, project through a central preferably removable bar or section 9 of the casting '5, -the projecting-portions of the rods 8 bein""thr'eaded for securing the'cover 7. Angle- 'ars '10 11 or equivalent supporting siding at Lead, in the county of Lawrence own in position. Fig. 3 is apartial horizontal section of one of the trays devices for the removable filter-trays 12 are secured to the inner walls of the vessel 1.
The filter-trays 12 may be of any suitable size or shape and are conveniently constructed of thin sheet metal having upper marginal inwardly-extending flanges 13 to prevent loss of pulp or solution. By the term "tray Patented March 13,1906.
is meant any receptacle of suitable dimen i sionsand capable of use forthe collection of the liquid; The bottoms of the trays are doubly reinforced to enablethem to withstand Without distortionthe high pressures which are referably used for the rapid and economical extraotion of ores and slimes. To
the under surface of the bottom of each tray are secured a fplurality of transverse bars 14 in the form 0 I-beams, as shown in Figs. 2 and 4, or in the form of integral webs 14 on the bottom of a cast-metal tray, as illustrated in Fig. 7. The upper surface of eachtray bottom is provided with a plurality of longitudinal stiffening and sup orting ribs 15,
referably formed by close -placed angleliars riveted or otherwise secured to the tray. These angle-bars serve also to support the filter-bed. I
' The filter-bed comprises a supporting foraminous sheet 16, shown as consisting of a heavy wire screen resting u on and supported by the angle-bars 15. A ltering layer 17 is supported thereon, and a protective screen or equivalent foraminous sheet 18 overlies the filtering layer. For the screens 16 18 a series of wires or bars, a perforated plate, or other equivalent device may be substituted. The edges of the filter-bed are supported by ribs or projections 19, carried by the trays and are marginally secured from above by bars 20 in such manner as to prevent passage of gas ,or li uid between the upper and lower ames o the trays otherwise than through the filter-bed. One or more intermediate bars 21 are provided for holding the filter-bed securely in position when pressure is applied through the feed end ofthe vessel 1 When the trays are secured in place, the feed-pipe 23 is brought into operative connection with apertures 24:, communicating with the upper compartment of each filter-tray. -A pipe 25 is carried by each tray and communicates with the lower compartment thereof, this pipe having external connection through nipples 26, passing through suitable stufling-boxes on the vessel 1. The discharge end of each tray is unobstructed and is provided with an outwardly-extending flange 27, which when the tray is in position is compressed against the packing 6 on the outer face of the casting 5. Thus the cover 7 constitutes one wall of each filtertray.
The apparatus may be variously modified.
Referring to Figs. 5, 6, 7, the vessel 1 is shown I as provided with external end flanges 28 29, conveniently of cast-iron. A cast-iron head or closure 30, Fig. 6, on the outer face of which the conduits 23 25 are cast or other wise secured, is adapted to be bolted to the flange 28, and a cast head 31 is detachably secured to the flange 29. In this construction provision is made for additional trays of appropriate size to be inserted through apertures 32 33. i The filter-trays may, if desired, be of cast-iron and may be bolted or otherwise secured to the head 30 to form an airtight joint therewith, as illustrated in Fig. 7. In the modification shown in Figs. 5, 6, 7, both ends of the several trays are formed by the separable heads of the extraction-tank.
The apparatus is adapted for the treatment of a wide variety of materials, and the nature of this treatment will vary according to the character of the ore and of the solvent. In general the pulp is distributed over the filter-bed and treated thereon with a solvent solution under such conditions of temperature and pressure as may be required. Usually a high pressure is applied above the ore, result ing in a hard and compact cake which cannot be flushed out from the vessel in the usual manner. A cake of this character is readily removed,however, through the discharge end of the filter-tray by tilting the vessel to a position at an angle with the horizontal and then applying a pressure of air or liquid below the filter-bed, whereby the cake is loosened and floated from the vessel. This method of discharging the cake renders necessary the special marginal and intermediate supports and reinforcing devices above the filter-bed, as well as the means for varying the inclination of the vessel.
