useful Improvements in'Apparatus for Re-.

moving Liquids from Solid Material, of

which the following is aspecification.

The present invention relates to an apparatus for simultaneously removing oil,

grease, water or other 'liquidsffrom garbage or other refuse matter and" compressing the residue of such matter, its important object being the production ofan apparatus which will introduce important economies in the separation of liquids from the solid matter in garbage, etc, by makingprovis'ion for Y the efiective use'of steam "in the performance of its herein functions of extrapting the liquids from the solid matter and compressing said solid matter and by also making provision whereb the compacted solid matter from which t e liquid content has'been extracted may be readily and economically removed from the separating apparatus.

In the accompanying drawing, I have shown several specifically different embodiments of the present invention, some of which embodiments arebetter adapted to carry out the particular purposes of the present invention than others, but all of which are capable of carrying such purposes into practice with more or less degree of satisfaction.

In said drawings: Figure 1 is a side elevation partly in section of one form of the apparatus. Fig. 2 is a side elevation, partly broken away, of .a form of the apparatus like that of Fig. 1 in many respects, but having a change which increases its eiticiency- Fig. 3 is an elevation, partly in section, of a conical. form of the apparatus.

Fig. 4 is a detail representation of the upper part of a modified form of conical apparatus, showing a form thereof-preferred to that illustrated in Fig. 3. Fig'. 5 is an elevation, partly broken away, showing a form and arrangement of the apparatus which is less desirable than any of the preceding forms but is within the s irit ofthe invention considered in its broa est aspects.

The present apparatus essentially includes a container having a chamber to which the garbage or other material to be treated is supplied through an aperture having communication with said chamber, said chamber also having an inner perforated wall and an outer non-perforated wall, the inner wall extending throughout a part only of the length of the treating chamber, terminating short of the charging aperture and steam inlet-sufliciently to provide between its end and said aperture and inlet a walled space within which the material is partly treated, said solid space having its wall formed without perforations, or at any rate, so formed that the steam which enters the treating chamber at a point in advance of the perforated inner wall will be compelled to pass through that portion of the matter which is surrounded by said imp erforate wall and will be permitted to compress said matter, before it reaches any of the outlets provided by the perforations in the inner wall, thereby enabling the steam to extract the liquid content of said matter and compress the solid residue without loss of steam. The apparatus also essentially includes certain other features hereinafter more particularly set forth. I

Referring to the construction illustrated by Fig. 1 of the drawing, the part lettered represents a container consisting of a cylindrical wall a terminating in a top a tightly secured thereto, from which rises a drum B, the drum B, top (1 and wall a all being steam-tight. The drum B.has a charging aperture which may be tightly closed by a closure C, preferably hinged to the' drum, and said drum also has a valved steam inlet pipe Dadjacent to said charging aperture. The bottom of the container is closed by a closure a which in this particular exemplification of the invention is hinged at a to the outer wall a and is tightly held in its space 1 between the walls of the container and a hinged section h which forms the bottom of the treating chamber, said hinged section having a diameter approximately equal to that of the treating chamber, being hingedly mounted at one side adjacent to the end of the perforated wall G and having at its opposite side a suitable securing device h This plate is spaced from the closure (1 so as to provide a chamber 2 which has communication with the annular space 1 through the perforations in the fixed section It and also has communication with the treating chamber through the perforations in the hinged section It. This chamber 2 is provided with a valved outlet pipe F through which the steam and liquid matter extracted from the matter undergoing treatment may be drawn.

The operation of the'apparatus is as foll0ws:-The plate or valve C is opened and garbage or other matter is charged through the drum B into the cylinder F until the garbagereaches the position in the drum ust below the inlet pipe D, when the valve ls closed and steam is $11, 11 admitted through the pipe D. The Steam will pass through the garbage, forcin and carrying out with it through the'pe orations in the cylinder G and the bottom a oil, water or other liquid which is collected in the spaces 1 and 2, and conducted'away. through the outlet pipes E, E and F. The pressure of the steam at the same time will compress the garbage and force it out of the drum B and compress it inthe cylinder G below the top.

of said cylinder. If the process be now continued without the addition of further material to that portionof the treatingchamber situated between .the inner perforated wall and the steam inletthe steam instead of passing through the garbage will escape through the perforations atthe top of the cylinder and pass out through space 1 and escape through the outlet pipes E, E, at a great'loss in steam. To prevent this loss, as soon as the garbage is forced to the bottom of thedrum-B, the steam is shut off, the plate 6 is opened and more garbage is charged into thedrum B up to the point D, when thetphateCis again closed and the steam again turned'on. This operation is repeated-until all the oil, water, &c., is forced out of the arbage and the same is pressed tightly inside the cylinder G. When this operation is completed the steam is shut off, the bottom a and the hinged plate H are opened and the substantially dry material is removed.

In an apparatus constructed as shown in Fig. 1, repeated rechar in of the drum therefore is necessary. 1115 not only takes up time but a large amount of steam is lost each time the valve C is opened. To overcome this objection, I may construct the apparatus as shown in Fig. 2. In this case instead of the inner perforated wall, marked G in thisfigure extending to the top a it is much shorter than the outer wall a. The upper edge of this inner perforated Wall Gr is outturnedto form a flan e g which tightly rests against the inner sur ace of the side a of the container. In this construction the treating chamber includes a space above the upper end of the. perforated wall G and between the same and the outlet end of that section of the treating chamber which is within the drum B, and as the garbage in the treating chamber must be forced below the flange g before the steam can freely escape, it Is not necessary to so frequently add the garbage to thetreating chamber during the operation of the apparatus.

A conical form of the apparatus is Preferable to a cylindrical form thereof. I have shown such a form in Figs. 3 and 4. In this form of the construction the inside perforated member, marked G in Fi 3, may extend substantially to the drum ,as shown in Fig. 3, or said inner perforated member marked G in Fig. 4 may be outturned to form a flange, marked 9, as 'shown in Fig. 4. In this construction I have also shown the bottom a of the conical section and the bottom'-'perforated plate h connected together. In other words, the bottom a is a double bottom having an inner perforated. plate h" with the space 20 between. In the conical form of apparatus the solid residue, that is, the. material left after the liquid content of the matter has been extracted may be more readily removed than in cylindrical construction. This removal of the solid matter is accomplished by opening the hinged bottom a said bottom moving to an open position on its hinge a and when in said -open position fully exposing the interior of the receptacle. This receptacle beingnow in downwardly open position and with its larger end at the bottom induces a movement of the solidmatter therefrom in a minimum length of time In some instances the garbage after being treated to remove the oil and other matter, may be easily removed from the receptacle by forcing compressed air in the top thereof through the pipe J. While I have shown this pipe as connected to the drum, it is apparent that it may be connected directly to the steam pipe D so that air can be forced into'the drum over'the top of the garbage after the steam is cut oif.

In some cases it may be advantageous to have the container placed horizontally instead of vertically. I have shown an apparatus so arranged in Fig. 5. In this construction the drum B is connected to the side ofthe container and it communicates with the inside-of the perforated cylinder through an o ening g thereon. K is a circular inclined plate which prevents the garbage, during the charging, from entering the space 1 and also prevents the steam from escaping in said space before passing through the garbage. In this construction each end of the receptacle A. is provided with a hinged cover a and each end of the receptacle is also provided with a perforated hinged cover It with a space 1 between each of said covers.

While I have stated that the inner wall is a perforated cylinder or cone, it is to be understood that these members may be made out of a wire netting or any other suitable 'material, and while'I haveshown an air pipe J only in the constructions illustratai by Figs. 3 and 4, it is understood that such a pipe may be connected to the construction shown in any of the other figures for the same purposes. While I have shown only in Fig. 3 the bottoms a and h 'connected together yet such a covermay be used in the construction shown in any of the other figures.

It will be noted that in each of the foregoing exemplifications of'the present invention the portion of the treating chamber having the perforated wall is entirely free from ledges and other projections, and that said portion of the treating chamber is similarly free from any elements which would form obstructions to the compressing of the solid residue or interfere with its free removal from the treating chamber when the outlet closure is adjusted to its open position.
