Patented April 20, 1909. I
To all whom it may concern:
Be it known that I, GEORGE B." FRANK- ron'rnn, a citizen of the United States, residing at Minneapolis, in the county of Homepin and State of Minnesota, have invented certain new and useful Improvements in Apparatus for Use in Extracting Turpentine and. Resinous Matter from Resinous Wood; and 1' do hereby declare the following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame. I
My invention has for its especial object to provide an improved a paratus for use in extracting turpentine an resinous matter from resinous wood, and other resin containing .materials, and to this end it consists of the %eferrin to the drawing, thenumeral 1 indicates a arge tank preferably horizontally disposed and constructed of steel, andwhich, on account of one of the functions which it performs, andifor the sake of definiteness-in the descriptionof the apparatus, T designate asa boiler. This boiler 1, as shown, is provided. at or near its bottom with a draw-oil cook or faucet 2, and at its top is provided with asafety valve 3 of the usual or'any suitable construction. y
,Located above the boiler -1 isa lurahty of so-ca'lled extraction chambers which are ada ted to contain the wood-or resin zcontainm' material. As shown, these extraction c ambers 4 are in the *form of n right metal drums and they are provided with-detachable bottoms '5 and removable upper end caps6,which parts 5 andt may be-detachably secured by means of threaded engagement,"
or by any other of the well known means'lor de'tacha'bly securing such parts.
Vapor delivery pipes 7 ,8 and Q'connect the v y t e boiler 1 with the upper upper portion of portions of the several extraction chambers 4. The pipes 9 terminate, within the respective extraction. chambers, in annular perforated spraying. sections 9. Return pipes 10 and 11 conneot-the lowe'r or bottom portions of the several-extraction chambers 4 with the. lower ortion of the boiler 1. Outlet pipes 12 lea, upward from the top of the several extraction chambers 4 and these outlet pipes 12 are connected by-an-endless pipe 13. In the-drawing, the several-extraction chambers 4 are shown as located in a row, but in practice they might be placed in circular arrangement and, of course, .any desired number of the said extraction chambers may be en1- ployed. The short pi e sections 14, as shown, connect the en less pipe 13 to the several pipes 9. Pipes 15 open into the lowerportions of the several extraction chambers 4, for a purpose which will hereinafter appear. Bent tubes 16 open to the atmosplere in the up or portions of the several extraction cham ers 4. These tubes, when partly filled with water or otherheavy liquid, constitute water traps or seals that are'normally closed.
' As one means for heating thecontents ofthe boiler 1, a closed steam conveying coil 17 leads from a suitable source of steam supply and extends along the inner lower 'portion'of said boiler.
The numeral 18 indicates an elevated wator-containing tank which is adapted to be supplied with cold water by any suitable connections (not shown). Within this tank 18 is a condensing coil, 19, the upperend of which is open'to the atmosphere, and to the lower end of which, as shown, are connected two pipes 20 and 21. The pipe 20 leads down-ward'and terminates in the-lower por; tion of the boiler 1, while the pipe 21 isdirectly connected, as "shown, to one of the pi es 10 and hence is indirectly connected to al of said pipes'lfl and to the pipe 11.
For purposes which will hereinafter appear the several pipes are provided with valves located as follows: Each pipe 9 is provided with a valve 22; each pipe 10 is provided with a valve 23; eachpipe 14 is provided with, a valve 24; each pipe 15 is provided with a valve 25; and the continuous pipe 13 is provided with valves 26 and 27. The valves 26 and 27 are located one at each side of each of theontlet pipes 12.
The wood in the form of chips, shavings,
excelsior or saw dust is, of course, placed in the respective extraction chambers, while the tops 6 thereof are removed and while the bottoms 5 thereof are secured in position. The
preferred manner for carrying out the improved process by means of the apparatus above described is as follows: One of the extraction chambers 4, let us assume the one at the left as shown in the drawing, is first filled'with the wood particles and the boiler 1 is partly filled with the solvent liquid, which we will assume to be petroleum ether which is a low boiling hydro-carbon compound havin the property of dissolving and holding in so ution turpentine and resinous matter. e will now assume that all of the valves 24, 25, 26 and 27\ are closed, that the valves 22 and 23 of the said first extraction chamber at the left are opened, and that all other of the valves 22 and 23 are closed. We will now assume that the solvent fluid 2 in the boiler 1 is heated to a temperature suflicient to vaporize the said solvent liquid which, if the samebe petroleum ether, requires a temperature above 55 degrees centi 'rade. The solvent vapor generated in the boiler 1 will pass upward through the pipes 7 and through the left hand i es 8 and 9 and spraying nozzle 9, and W31 e discharged into the left hand extraction chamber 4 and directly upon the wood particles g confined in said extraction chamber. The vaporized solvent fluid upon coolin will condense within the said extraction chamber 4 and will trickle down upon the wood particles and will dissolve and take into solution the tur entine and resinous .matter thereof, and rom said extraction chamber will flow back through the left hand pipe 10 and the return pipe 11 into the boiler 1. By the steam coil 17 or other suitable means, the temperature of the liquid within the boiler l is kept up to the boiling temperature of the said solvent liquid, so that the said solvent liquid is continuously vaporized and caused to travel the course just described, through the extraction chamber noted and through the wood particles contained therein, and thence back to the boiler. The solvent liquid is revaporized by a temperature which is insufficient to vaporize either the turpentine or the resinous matter and, hence, the said turpentine and resinous matter is continuously deposited in the bottom of said boiler, from which boiler it may, from time to time, be drawn off through the faucet 2. I I
After completion of the extraction of the turpentine and resinous matter from the wood contained in the said extraction chamher at the left, the valves 22, 23, 24 and 26 adjacent thereto, should be closed and the valves 25 and 27 adjacent thereto should be opened and also the valves 26 of the second or intermediate extraction chamber should be opened. The opening of the valves 25 will permit the reclaiming fluid, which we will assume to be water, to run into and fill the said first or left hand extraction chamber, thereby forcing the lighter solvent fluid out of the said first extraction chamber and into the second or intermediate extraction chamber. In this way, the solvent fluid left in the first extraction chamber, after the extraction of turpentine and resinous matter froin the wood has been completed, is not only reclaimed and saved, but is. forced into the second extraction chamber. In practice, the so-called second or intermediate extraction chamber should be filled with the wood particles while the extraction of turpentine and resinous matter from the wood contained in the first extraction chamber is taking place.
The crooked tubes 16 which constitute a sealing device and which normally contain water or other liquid, are preferably made of glass, so that the operator can tell, by observin the upward movement of the liquid in said tube, when the extraction chamber has been filled with the water or other reclaiming fluid. After the first or left hand extraction chamber has been filled with the reclaimingliquid, and the solvent liquid has been forced out of the same, the valve 27 thereof should be closed to prevent the backward flow of the said solvent liquid. The said reclaiming liquid may be drawn off from the extraction chamber by any suitable device as, for instance, by allowing it to run backward throu h the ipe 15; or it may be removed from the sai extraction chamber together with the wood particles, when the bottom 5 of the said chamber is removed.
The above arrangement, as is evident, makes it possible to continuously carry out the process of extracting the turpentine and resinous matter by always rendering available for use at least one of the extraction chambers.
Any of the solvent li uid which may be converted into vapor wit in any of the pipes 10 or 11 may rise through the pipe 21 into the open coil 19 where it will be condensed and from thence may run back to the boiler 1 through. the pipe 20.
With the apparatus above described, it is possible to have two or more of the extraction chambers in action at one time. Before the faucet 2 is opened up to draw off the turpentine and resinous matter, it is advisable first to close the valves 23 in the return pipes and to open the valves 22 in the supply pipes 9, and by thev application of heat to the contents of the boiler l to vaporize the solvent liquid and drive the same from the boiler into the extraction chambers.
What I claim is:
1. In an. apparatus of the kind described, the combination with a boiler, of a plurality of extraction chambers located above the same, conduits leading from the upper portion of said boiler to the upper portions of said extraction chambers, return conduits leading from the lower ortions of said extraction chambers bac to said common boiler, a conduit connecting the u per portions of the several extraction cham ers, and other conduits o ening into said extraction chambers, for de ivering thereto a reclaiming fluid, and valves in the several conduits,
whereby the several extraction chambers,
may beiused successively in connection with said common boiler, substantially as described.
2. In an apparatus, of the kind described, the combination with a boiler, of an extraction chamber located above the same and provided with a removable cap and a removable bottom, of a conduit leading from the upper portion of said boiler to the upper portion '0 saidextraction chamber and a return. conduit leading from the lower portion of said extraction chambers back to the lower ortion'of said boiler, substantially as descri ed.
In testimony whereof I afiix my'signature in presence of two Witnesses.
