To all whom it may concern:
Be it known that we, RUD'onr 'ERNST WAG- NER and Joint: DANIEL-IILLGREN, subjects of the King of Sweden, and residents, respectively, of Karlstad, Sweden, and Stocksund, Sweden, ful Improvement in Apparatusfor Separating Liquids from Solid Bodies Mixed or Suspende Therein (for which an application for patent has been filed in Sweden, October 27, 1921), of which the following is a specification.
In the manufacture of wood-pulp and cellulose use is made, as is well known, of pulp collectin machines, so-called wet-machines, for co lecting and shaping a layer or web of material out of the pulp which is diluted with water so that it is more or less liquid, said web being afterwards conducted to the drying machine for further treat-- ment. Such ulp collecting machines, which thus rende-rthe same service as an ordinary wire-part, have hitherto consisted of. a cylinde'r of strainer cloth which rotates more or less immersed in a pulp container, and on which the pulp settles or collects by straining augmented by suction, if desired, so that a layer or'web is formed on the cylinder which is thenremoved from the same.
According to the present invention use is made of an endless wire apron which runs throu h a pulp container and which is supported by a roller which is provided with slots, grooves, or other such similarcavities which are'capable of extending to that portion' of the surface of the roller against which the wire apron bears, the suction from one or more suction boxes attached to a 40 greater or less portion of the remaining surface of the roller.
In the accompanying drawing an embodiment of the invention is illustrated diagrammatically and by way of example.
In the pul container 1 or adjacent the same there is rotatably journalled a roller 2.
Around said roller 2 which, in the embodiment illustrated, is provided with circumferential slots or grooves 3, there is placed a wire apron 4 which may thus-be deemed to form one wall of-the pulpcontainer 1. The wire apron 4: runs over suitable guide and stretch rollers 5, 6. A suction box 7 have invented a new and use-'- is attached to the lowerside of the roller 2 which is not covered by the wire apron 4. The roller 2 is rotated in the direction indicated by the arrow. The wire apron 4 will thus of course move upwards in the pulp container at the bottom of which a suitable packing 8 is provided. During the upward movement of the wire apron in the pulp container the pulp in said container will settle or collect on the wire apron, particularly on that portion of the apron which rests on the roller, owing to the suction in the suction box 7 extending through the slots 3 up to said portion and cooperating to rapidly remove the water straining through the wire apron, and to conduct said water away to the suction box from which it is removed in any suitable manner. this manner a pulp layer or web 9 is formed on the wire apron, which web after having become raised out of the pulp container 1 at the upper part of the roller, is still subjected to suction and thereby further freed from water, until the wire apron leaves the roller after which the'pulp web may be removed from the wire apron in suitable manner and be transferred, for instance, to a felt 10 which transports the pulp web to thepresses in the drying machine.
The suction box may be provided with a partition 15, as shown in dotted and dashed lines, which reaches from the bottom of the box to the surface of the roller 2 and which divides the box into two chambers 16 and 17 to each of which a suction conduit is attached; The liquid collected in the chamber 16 will contain a certain amount of pulp cleansing the same, said water being also drawn into the chamber 17.
It will be understood that the invention is notlimited to the employment of a roller 2 having slots or grooves, but he roller may be provided with any such cavities or the like which are capable of transmitting and conveying along the outside of the roller the suction from the suction box to that portion of the roller which supports the wire apron. It will also be understood that the suction box need not cover the entire remaining portion of the roller, but it is also possible to use, for instance, one suction box in each angle between the wire apron and theroller surface, or even only one suction box in that angle between the roller surface and the wire apron Where said apron enters the pulp container, and other similar changes and modifications may be effected within the scope of the invention.
In similar manner as in other wet-machines'there may be provided a roller 11, also shown in dot-ted and dashed lines, which presses against the roller 2 on the upper free side of the same, that is to say on the upper left-hand side in the drawing. Said roller -11 will thus press against the pulp web 9, 9 formed onthe wire apron 4, 4 whereby an increased pressing out of the water is obtained. Over said second roller 11 a felt 12 may be run, and between said felt and the roller 11, particularly if this latter is also provided with circumferential slots 13 or the like, suction boxes 14: may be provided for removing the water which is pressed through the felt. By this arrangement it is possible by means of the felt to remove the pulp web 9 fromthe wire a ron. By the arrangement above describe the apparatus becomes 'a combined wet-machine and wet-press. r
It will be understood that the apparatus according to the invention may also be used for separating liquid from other bodies than wood-pulp or cellulose fibres, for instance for purifying waste liquors from the cellulose manufacture from lime and other particles.
