Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Gegenstand vorliegender Erfindung ist ein Filter, dessen feste oder bewegliche Filterwand beständig von den Rückständen gereinigt wird, welche sich auf ihr absetzen. Dasselbe eignet sich besonders zur Filtration der Grünsyrupe der Zuckerfabriken und -Raffinerien.The present invention relates to a filter, its fixed or movable filter wall is constantly cleaned of the residues that settle on it. Same thing particularly suitable for the filtration of green syrups in sugar factories and refineries.

Das auf beiliegender Zeichnung im Verticalschnitt dargestellte Filter besteht aus einer Filtrationskammer a, deren innere Wandung von einer gewissen Höhe ab durchlocht ist. Gegen diesen durchlochten Theil legt sich das Filtergewebe r. Dasselbe wird oben und unten von den Reifen t begrenzt. Die in der Mitte der Kammer angeordnete Welle d läuft unten in dem Lager k, welches in dem konischen Ansatz η durch den Arm kl in seiner Lage erhalten wird. Die Welle wird durch die im Deckel b des Filters vorgesehene Stopfbüchse i geführt und von der auf Böcken h ruhenden Antriebswelle g vermittelst der Uebertragung/ in Rotation versetzt.The filter shown in the accompanying drawing in vertical section consists of a filtration chamber a, the inner wall of which is perforated from a certain height. The filter fabric r lies against this perforated part. The same is delimited above and below by the tires t. The shaft d arranged in the middle of the chamber runs down in the bearing k, which is kept in its position in the conical projection η by the arm k l. The shaft is guided through the stuffing box i provided in the cover b of the filter and set in rotation by the drive shaft g resting on brackets h by means of the transmission /.

An der Welle d sind Arme m angeordnet, welche in horizontaler Richtung unter einem Winkel von 90° gegen einander versetzt sind und am Ende mit ausgebohrten Ansätzen m1 versehene, schraubenartig gewundene Abstreicher / tragen. Dieselben bestehen aus zwei festen Leisten, zwischen deren Rändern eine Kautschukleiste Z1 fest eingepafst ist. Die über die Arme m geschobenen Federn ρ legen sich gegen den Abstreicher und pressen die Kautschukleiste Z1 mit gewissem Druck gegen die innere Fläche des Filtrirgewebes r, so dafs bei Drehung der Welle d von diesem alle Filtrationsrückstände entfernt werden.On the shaft d arms m are arranged, which are offset from one another in the horizontal direction at an angle of 90 ° and at the end carry screw-like wound scrapers / provided with drilled lugs m 1. The same consist of two solid strips, between the edges of which a rubber strip Z 1 is firmly fitted. The springs ρ pushed over the arms m lie against the scraper and press the rubber strip Z 1 with a certain pressure against the inner surface of the filter fabric r so that all filtration residues are removed from it when the shaft d rotates.

Die Flüssigkeit tritt bei e in das Filter und dringt durch das Filtergewebe r und die durchbrochene Filterwand α in den Raum j, wobei die rotirenden Abstreicher I die Innenseite des Gewebes beständig für die nachfliefsende Flüssigkeit freilegen. Die filtrirte Flüssigkeit gelangt in den unteren vollwandigen Theil 5·1 und kann . durch Rohre s abgezogen werden.The liquid enters the filter at e and penetrates through the filter cloth r and the perforated filter wall α into the space j, the rotating scrapers I constantly exposing the inside of the cloth for the liquid flowing in. The filtered liquid reaches the lower full-walled part 5 x 1 and can. be withdrawn through pipes s.

Die Rückstände sammeln sich unterhalb des von den Armen / bestrichenen Raumes und in dem konischen Gehäuseansatz n. Durch Oefifnen der Klappe 0 können dieselben aus dem Filter entfernt werden.The residues collect below the space covered by the arms / painted and in the conical housing extension n. By opening the flap 0 , the same can be removed from the filter.

Um das Innere der Filterkammer zu reinigen, Iäfst man Dampf oder Wasser durch das Rohr c1 treten. Hierbei nimmt das Reinigungsmittel denselben Weg wie die zu . filtrirende Flüssigkeit. . Soll die Reinigung in entgegengesetzter Weise vor sich gehen, so Iäfst man den Dampf durch ein zweites Rohr c2- in den Raum j eintreten.In order to clean the inside of the filter chamber, steam or water is allowed to pass through the pipe c 1 . Here, the detergent takes the same path as that. filtering liquid. . If the cleaning is to be carried out in the opposite way, the steam is let out through a second pipe c 2 - into space j .
