APPARATUS FOR EXTRACTING OIL AND MOISTURE FROM MATERIALS.
SPECIFICATION forming part of Letters Patent No. 795,183, dated July 18, 1905.
Application filed May 19,1904, Serial No. 208.785.
To (all whom, it may concern:
Be it known that I, STEPHEN E. WILSON, a citizen of the United States, residing at Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Apparatus for Extracting Oil and Moisture from Materials, of which the following is a specification.
My present invention pertains to an improved apparatus for extracting oil and moisture from materials, particularly those in which the oil or grease is of such nature that it is necessary to heat the material in order to effect the proper extraction of the fatty matter. In other words, the invention is especially applicable to materials wherein the contained grease will congeal at ordinary temperatures-such, for instance, as tankage, slaughter-house refuse, and the like-though, of course, the apparatus described herein is equally applicable to cases in which the oil will flow at ordinary temperatures and with the usual pressure, the rate of flow, however, being hastened and the extraction rendered more nearly complete by the use of my apparatus.
In the drawings I have illustrated the apparatus in conjunction with a hydraulic press, wherein- Figure 1 is a vertical sectional view of the apparatus, the trays, with the exception of the lowermost, being omitted; Fig. 2, a perspective view of the inclosing shell or casing, and Fig. 3 a horizontal sectional view on the line 3 3 of Fig. 2.
The object of the invention is to provide an apparatus whereby the oil and moisture con tained in a mass or charge or a series of charges of material which is undergoing compression may be readily forced out, with the result that a greater amount of grease or oil is obtained and likewise a resultant or residuary product secured which is of greater value for many purposes on account of the small percentage of grease or moisture remaining therein.
In the drawings, A denotes the base or bed of the press; B, the platen or abutment; O, the strain rods or columns,and D the fixed head or abutment, formed of I-beams and carrying a secondary head or abutment E, all of which parts are of the usual and well-known construction.
The space between the head or abutment E and the pan E, which latter is carried by the platen or abutment B, is inclosed by a suitable casing comprising walls G and a removable door or closure H. The walls are bolted to and suspended from L -shaped irons I, which in turn are connected to distance-plates J, secured to the upper face of the secondary abutment E. A pocket or double-walled section K is secured to said abutment and is designed to receive the upper edge of the door H when the latter is in position, the door being maintained in place by suitable gravitating hooks L, which pass into openings formed near the upper edge of the door.
Any form of sustaining device for the door may be employed, as well as any form of pocket or the like which will make a substantially steam-tight joint at the upper edge of the door or closure. A wing M is provided on each vertical edge of the door, said wings overlapping the side walls and preventing substantially the passage of steam at these points.
The walls and the door or closure are each provided with a depending sliding section N, said sections being formed with vertically-dis posed slots O, through which pass bolts 1 The outer ends of the bolts are covered by poekets or shields Q, which prevent the escape of steam through the slots, while at the same time permitting the sliding sections to be moved upwardly by the pan E, upon which the lower edges of said sections rest. Steam, either live or exhaust, will be introduced into the housing thus formed through a pipe or pipes R, preferably opening into the housing near the upper end thereof. In practice said pipe may be connected to the exhaust of the pump which operates the press or any other service.
In the operation 01? the apparatus, assuming that tankage be the material under treatment, the trays, with the cloth-incased charges or cakes thereon, are run into the housing or casing, the door or closure having been removed. By the employment of the extension or distance plates J the housing is made sufficientlylarge to permit the stacked and loaded 1 freely. During the latter portion of the optrays to be readily introduced and likewise Withdrawn after the pressing operation, it being, of course, difficult to stack the trays with perfect regularity in the first instance and the pressing operation frequently causing them to become still further displaced. After the press is charged and the closure secured in place steam is admitted through pipe R or other suitable source, the pressing being commenced at the same time. Asthe pan ascends the sliding or telescopic sections N are elevated, said sections and the stationary walls serving to direct all the fluid to the pan, thereby rendering the surroundings of the press comparatively dry and clean. Meanwhile steam is filling the housing, coming into contact substantially with all portions of each separate and distinct charge, passing through and around the slotted trays, keeping the entire mass warm, and preventing the grease contained therein from becoming congealed.
It will be seen that the steam not only keeps the trays clean, but also the cloths, thereby insuring a more ready flow of the oil or grease and the water contained in the charge. The hot water of condensation assists in the flow of the oil, the result being that a greater amount of fatty matter is abstracted, as well as a larger percentage of water. The flowing oil will be associated with a certain amount of water, and the water when passing off will also carry with it some of the oil. It will therefore be seen that not only is a greater quantity of grease and water abstracted from the charge, but the resulting mass is also lighter in weight by reason of the loss of these materials. The mass in such condition is consequently a more valuable product, inasmuch as the cost of transporting the same is reduced, and it is also more desirable as a component for fertilizers.
It is, of course, manifest that an inverted press could be fitted up with the inclosing shell or casing, and it is likewise evident that a plurality of telescoping sections may be employed in building up the structure.
An additional door may be provided in case it is desired to introduce and withdraw the trays upon opposite sides of the press.
While the sections N are shown as resting on the pan, it is to be understood that they may not occupy this position during the first part of the pressing operation, but come into contact with the pan after the same has moved upwardly a slight distance. In fact, it is possible that the upper portion only of the press need be inclosed or surrounded by the shell, the steam, of course, being retained therein until the shell is entirely filled and the shell remaining filled so long as steam is introduced into the same.
Ordinarily the material is placed in the press in a warm or hot condition, and during the initial pressing operation the liquor will flow eration, however, the grease will congeal, and it is at this stage that the application of steam is especially beneficial. The steam may also be introduced under pressure, which will have the effect of more thoroughly extracting the oil, not only by reason of such pressure, but on account of the resultant increase in temperature.
Having thus described my invention, What I claim, and desire to secure by Letters Patent, isp 1. In combination with a press; an inclosing shell or casing; and means for introducing steam into said casing while the press is in operation and directly upon the material being pressed, substantially as described.
