Description
P. REINICKE. PULP SIRAINER.
I Patented July 11, 1893.
(No Model.)
k;l\10.5o1,2l4.
UNITED STATES PATENT OFFICEo PAUL REINICKE, OF COETHEN, GERMANY. I
-PuLP-STRAINER.
SPECIFICATION forming part of Letters Patent No. 501,214, dated July 11, 1893.l
Application filed February 8, 1893.
To all whom it may concern:
Be it known that I, PAUL REINICKE, a subject of the Duke of Anhalt-Dessau and of the German Emperor, and a resident of the city of Coethen, in the Dukedom of Anhalt-Dessau, Germany, have invented certain new and useful Improvements in Pulp-Strainers, of which the following is a specification.
This invention relates to a device for straining wood and other pulps; and the object of my invention is to provide a strainer which is so constructed as to give the greatest possible strainer area in a small space and at the same time be simple in construction.
The invention also consists in the construction and lcombination of parts and details which will be fully described hereinafter and finally pointed out in the claim.
In the accompanying drawings, Figure lis a longitudinal sectional view of myirnproved pulp strainer, parts being broken out and others shown in elevation. Fig. 2 is a vertical transverse sectional view through the strainer, and Fig. 3 is a detail vertical seotional view of one compartment, showing a modified construction and arrangement.
Similar letters of reference indicate corresponding parts.
The annular strainers or screens b are arranged parallel and separated a short distance from each other so as to form strainer compartments. Between each two screens b an agitating disk a is arranged, which several agitating disks are mounted concentrically on a shaft n passing 4centrally through the annular screens. Between each two agitating disks athe screens are securely connected by the walls c of a casing, and the several walls c rest upon a base e, which also forms a support for the walls l surrounding the above described cas'ing. Stuffing boxes d are arranged in the walls Z and through the same the'shaft 'n passes in such a manner that it-can rotate and move longitudinally. The walls c divide the space bounded by the walls Z in two parts. Into one of them the wood pulp, milk of lime, kaoline pulp or other matter to be treated runs from the trough fm by means of the inlet necks 0. The rest of the space is occupied by the pulp that has passed the screens serial No. 461,478. (No modem' and contains only the strained pulp, which can pass off through the outlet p, The shaft n is provided at one end with a xed pulley g-having a cam-groove into which a fixed pin i projects. If the shaft n is rotated by means of the belt-pulley k, the action of the pin c' on the cam-groove of the pulley g causes the shaft n to reciprocate in the direction of its length, so that the' agitating disks a move to and fro between the annular screens at each side thereof. As they. also rotate, they keep the pulp in constant motion and prevent the coarse particles from closing the screen slots. The coarse particles collect in the bottom parts of the spaces between the screens and pass from the same into a channel f, which may be provided with a device for closing its end, which is not shown, so as to permit of opening said channel when it is necessary to discharge solid particles accumulating in the same.
Instead of mounting the agitating disks in such a manner that they move axially to and fro between the screens, they can be mounted on the shaft n at an inclination, as shown in Fig. 3, and in this case there would be no necessity of mounting the shaft n to reciprocate, as the shaft in rotating would constantly beat and agitate the pulp .and press it alternately against the opposite screens.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
In a pulp strainer, the combination, of a casing divided into a series of compartments, the side walls of whichare formed of annular screens or strainers placed vertically, a ro* tative shaft mounted horizontally and pass-v ing through the several compartments, and a disk fixed on the shaft within each compart-v PAUL REINICKE.
