UNITED STATES PATEN OFFICE RICHARD '1. LANG, 01' wnmwxnu, NEW JERSEY. 8813110! TO HIGH VOI'I'E OONTAOT COIPANY,'INGOBPORATED, DI NEW YORK, Y A COBTOBATION m YORK rm scnzw rams Application ma rem-u 11, 1921. Serial Io. 107.414.
, This invention relates to screw presses for removin liquidsfrom pul or t e l1ke especially for use in paper an 'pul ,mills, and it has for its object to improve t e construc- .5 tion and the operationof such presses so as to obtain a greaterand more uniform dryness of the whole mass of pulp when it leaves the machine.
According to the presentinvention I deiO vised a new and improved screw press in combination with a particularly shaped outlet spout and a plug cooperating with the latter in such a way that the pulp passes from the screw room into a space of larger cross sectional area, whereafter the pulp 1s forced through a narrow passage with continuously decreasing cross sectional area. It is a part of my invention to form this passage by a conically enlarged outlet spout and a conical plug within the latter, both parts, the spout and the plug, being provided with perforations which allow the liquid contained in the pulp to drain oif from both sides through these perforations. p The invention consists further in providing such pulp treating apparatus, in which the mass of the pulp, after having left the screw room proper for theoutlet compartment or spout, is more or less broken up on account of the change in area and is then formed into a relatively thin layer between the inner face of the outlet spout and the plug. Thisforming of the pulp into a thin layer and subjecting the latter to a second pressing out has the advantage of allowing a very easy removal of the liquid from bothsides of the layer, thus insuring a uniform dryness of the pulp over its entire mass when it leaves the screw press.
It is an essential feature in my invention that by my new method and apparatus for pressing the pulp outinto the form of a thin layer and expelling thereby the liquid to both sides of this layer, a very high and uniform dryness of the pulp over its entire mass may be obtained even with a screw press having a solid screw of large diameter and deep threads. With the screw having these improvements of a conical and perforated outlet spout and plug av much higher percentage of moisture can be removed from the pals than with the present type of not perfo outlet spout and plu In the drawings ferred embodiments for carrying out the invention, whereby the same or similar arts in the difierent figures are marked by t e same numbers of reference.
1 and 2 represent a horizontal and a vertical longitudinal section respectively through the outlet end of a first embodiment of my new and improved screw press which is rovided with solid screw; 1
lg. 3 is a side view of the outlet lookin towards the press, from the right side 0 Fig. 2;
Figs. 4 and 5 represent the same sections-as Figs. 1 and 2 but through a modified construction,.in which the screw press is provided with a hollow screw.
In both examples the screw press casin 11 forms the press room, and the perfora shell 12 separates'the press room from the the front end of the screw press casing is fixed have shown two prescrew room, which contains the screw 13. To
the perforated outlet spout 14 of preferably conical shape, and a perforated plug 15 which is rather sharp pointed, extends with its point into the interior of the outlet spout, leavin however in the spout a certain amount 0 free space.
A handwheel 20 serves for moving the plug towards or away from the outlet spout, thereby decreasing or increasing the area of the angular ring space between the outlet spout and the plug, and thereby controlling the pressure in the screw chamber and in the outlet spout. The arms 21 hold cross head 19 fastened to the plug 15.0f the screw press.
In order to make the mounting of the plug yieldablc, the spindle 18 may be guided only 1n the hub 19 and a spiral spring 22 resting at one side against hub 19 and at the other side against the threaded spring cup or nut 23 which, when turned, moves towards or away from the hub 19 or the cross head 21, thereby increasing or decreasing the pressure of the spring exercised on the plug 15. The gutters 24 and 25 serve for collecting the liquid which drains off through the perforations in the outlet spout 14 or the plug 15 respectively, whilst the dewatered pulp leaves the press at 26.
Instead of roviding the gutter 24 the outlet spout can be s aped in such a way so as to form a chamber in which the liquid pressed out w collects, and which chamber connects to the discharge pipes in the press room.
In Figs. 4 and 5 the construction is similar except that the screw 13 is hollow and perforated and the end thereof projects out of the spout 14; and the plug encircles this projecting end.
Likewise the shape of the outlet spout and of the plug can be varied without departing from the spirit of my invention.
I claim:
A press of the character described comprising a perforated tube, a screw therein, said tube having a discharge end provided with an outwardly flaring perforated wall, a plug movable within said discharge end of the tube and also having a perforated wall opposed to said perforated wall of the discharge end of the tube and cooperating therewith to cause liquid to be exuded from the material through the perforations of each of said walls, and means for adjusting said plug mounted upon the perforated end of the tube by spaced supports constituting guides for said plug. a
In testimony that I claim the foregoing as my inventlon, I have signed my name RICHARD T; LANG.
hereto.
