Description

Bandfilter mit Vakuumsaugraum für das Filtrat unterhalb des oberen Trumes Die Erfindung betrifft ein Bandfilter mit Vakuumsaugraum für das Filtrat unterhalb des oberen Trum es des Bandfilters mit Trägerrost und beidseitigen Kettenführungen.Belt filter with vacuum suction space for the filtrate below the upper one Trumes The invention relates to a belt filter with a vacuum suction space for the filtrate below the upper run of the belt filter with support grid and chain guides on both sides.

Zur Filtration von Trüben und zur Entfeuchtung von Schlämmen werden mit Erfolg unter anderem kontinuierlich arbeitende Papier- und Gewebebandfilter verwendet, deren offene Bauweise auf der Seite des Aufgaberaumes viele Vorteile im großtechnischen Einsatz bietet. Ihr Anwendungsbereich ist begrenzt durch die der statischen Flüssigkeitshöhe im Aufgaberaum proportionale Durchsatzleistung, die besonders niedrig liegt bei hochviskosen Flüssigkeiten. Das Aufbringen einer Vorfilterschicht zur Erreichung hoher Filterfeinheit ist aus den gleichen Gründen bei diesen Filtern nicht wirtschaftlich. Can be used for the filtration of turbidity and for the dehumidification of sludge with success, among other things, continuously working paper and fabric belt filters used, whose open design has many advantages on the side of the task area in large-scale use. Its scope is limited by the throughput proportional to the static liquid level in the feed area, which is particularly low for highly viscous liquids. Applying a Pre-filter layer to achieve high filter fineness is for the same reasons not economical with these filters.

Zur Überwindung des Nachteiles der geringen Durchsatzleistung bei hochviskosen Flüssigkeiten und Schlämmen wurden Bandfilter mit unter dem Filterband angeordneten Vakuumkästen oder -zellen vorgeschlagen und teilweise gebaut. Die auftretenden Schwierigkeiten bei der Abdichtung und Gestaltung tragfähiger Trägerbänder haben sehr bald gezeigt, daß ein befriedigender Betrieb mit diesen Filtern nicht zu erreichen ist. Sowohl an den Seiten als auch am Ein-und Auslauf wurden wenig wirksame Abdichtungen erzielt, wobei die Tragbänder hohem Verschleiß unterlagen. Demzufolge wurden nur geringe Erhöhungen der Filterdifferenzdrücke gegenüber den Filtern ohne Unterdruckkammer erreicht. To overcome the disadvantage of the low throughput Highly viscous liquids and slurries were belt filters with under the filter belt arranged vacuum boxes or cells proposed and partially built. The occurring Have difficulties in sealing and designing load-bearing carrier tapes very soon showed that satisfactory operation could not be achieved with these filters is. Both the sides and the inlet and outlet were ineffective seals achieved, the fastener tapes were subject to high wear. As a result, only slight increases in the filter differential pressures compared to filters without a vacuum chamber achieved.

Bei bekannten Siebmaschinen, die für gleichartige Reinigungs- oder Filterzwecke verwendet werden, sind zur Abdichtung der bewegten Teile der Filter zwischen Schmutz- und Reinseite entweder möglichst enge Spalten mit druckbelasteten Lippendichtungen oder größere Spalten mit Blähkörperdichtungen vorgesehen. Dabei werden zur Verringerung der Reibung und Verbesserung der Abdichtung teilweise Abdichtflüssigkeiten zwischen Dichtelement und bewegte Maschinenteile geführt. Diese bekannten Siebmaschinen haben aber den Nachteil, daß sie bei innerer Beaufschlagung nur schwierig zu reinigen sind und außerdem allgemein bei runder Bauart zur Erzielung großer Leistungen und einwandfreier kontinuierlicher Filterflächenreinigung bei großem Platzbedarf sehr teuer werden. In known screening machines that are used for similar cleaning or Filtering purposes are used to seal the moving parts of the filter between the dirty and clean side either the narrowest possible gaps with pressure-loaded gaps Lip seals or larger gaps with inflatable seals are provided. Included Sometimes sealing liquids are used to reduce friction and improve sealing guided between sealing element and moving machine parts. These well-known screening machines but have the disadvantage that they are difficult to clean when exposed internally are and also generally with a round design to achieve great performance and flawless continuous filter surface cleaning with large space requirements get expensive.

Der Erfindung liegt die Aufgabe zugrunde, bei an sich bekannter kontinuierlicher und einwandfreier Reinigung der Filterflächen und Austragung der ausgefilterten Verschmutzungen die Abdichtung am Anfang und am Ende des Filterbandes sowie die seitlichen Abdichtungen des Bandes im Bereich der Saug- zone bei möglichst hohem Unterdruck in dem unter dem Filterband angeordneten Vakuumkasten zu verbessern. The invention is based on the object of known continuous and perfect cleaning of the filter surfaces and discharge of the filtered ones Soiling the seal at the beginning and at the end of the filter belt as well as the lateral sealing of the belt in the area of the suction zone at the highest possible To improve negative pressure in the vacuum box arranged under the filter belt.

Diese Aufgabe wird dadurch gelöst, daß am Anfang und am Ende des unter Saugwirkung stehenden Filtrationsbereiches eine mehrstufige Spaltabdichtung mit Sperrflüssigkeit für das endlose Filterband mit Rost liegt und für die beidseitigen Bandführungen zur Verbesserung der Abdichtung zwischen die abzudichtenden Flächen Filtrat aus den Öffnungen zuführbar ist. This object is achieved in that at the beginning and at the end of the a multi-stage gap seal in the filtration area under suction with sealing liquid for the endless filter belt with grate and for the two-sided Tape guides to improve the seal between the surfaces to be sealed Filtrate can be fed from the openings.

Hierdurch ist die Filterleistung erhöht und eine bessere Entwässerung von Schlämmen sowie die Filtration von hochviskoser Flüssigkeit möglich. In vorteilhafter Weise kann auf dem Filterband mit einer Voranschwemmung gearbeitet werden. This increases the filter performance and improves drainage of sludge and the filtration of highly viscous liquids are possible. In advantageous Way can be worked on the filter belt with a precoat.

Die Erfindung ist an Hand eines Ausführungsbeispieles in den Zeichnungen erläutert. Es zeigt F i g. 1 ein Bandfilter im Aufriß, F i g. 2 einen Querschnitt nach Schnittlinie A-A in Fig. 1, Fig. 3 einen vergrößerten Aufriß des Bandes im Bereich des einen Endes oder des Auslaufes und F i g. 4 einen Querschnitt der teilweisen Vorrichtung nach Schnittlinie B-B in F i g. 1. The invention is based on an exemplary embodiment in the drawings explained. It shows F i g. 1 shows a band filter in elevation, FIG. 2 a cross section along section line A-A in Fig. 1, Fig. 3 is an enlarged elevation of the tape in Area of one end or the outlet and F i g. 4 shows a cross section of the partial Device according to section line B-B in F i g. 1.

Wie F i g. 1 zeigt, fließt die Trübe 1 über einen Verteiler 2 in den Aufgabe- oder Rückstandsraum 3, welcher in bekannter Weise wannenförmig ausgebildet ist. Die Filterfläche 4 besteht aus einem endlosen Webstoffband, z. B. aus künstlichen Fasern, und kann zusätzlich mit Filtervlies 5 und/oder einem anderen Filterhilfsmittel, z. B. Filtererde 6, belegt werden. Like F i g. 1 shows, the pulp 1 flows through a distributor 2 in the task or residue space 3, which is formed trough-shaped in a known manner is. The filter surface 4 consists of an endless woven fabric band, e.g. B. from artificial Fibers, and can additionally with filter fleece 5 and / or another filter aid, z. B. filter earth 6, are occupied.

Diese Filtermittel ruhen auf einem endlosen, beiderseits an Ketten 7 geführten Rost 8, unter dem im Filterraum 9 ein Vakuum ansteht, das durch Pumpe 10 oder durch Absenken des Filtratspiegels im Raum 9 durch Pumpe 14 aufrechterhalten wird und in den das Filtrat fließt. Der die Filtermittel tragende Kettenrost wird von dem Getriebe 11 kontinuierlich oder nach automatisch gesteuerten Zeitintervallen oder in Abhängigkeit von der durch die Filtermittelverschmutzung bedingten Flüssigkeitshöhe im Rückstandsraum weitergefördert. Das aus der Filterwanne auslaufende endlose Webstoffband wird während des Laufens mittels einer Blasdüsenreihe 12 gesäubert. Die Abförderung des Filtrates geschieht durch ein barometrisches Fallrohr 13 oder eine Filtratpumpe 14. Die notwendige Menge Filtrat zum Zwecke der Abdichtung wird entweder aus der Pumpendruckleitung 30 entnommen 6der es kann ein eigener Kreislauf mit der Pumpe 15 vorgesehen werden.These filter media rest on an endless chain on both sides 7 guided grate 8, under which there is a vacuum in the filter chamber 9, which is generated by a pump 10 or by lowering the filtrate level in space 9 by pump 14 and into which the filtrate flows. The chain grate carrying the filter media will from the transmission 11 continuously or at automatically controlled time intervals or as a function of the liquid level caused by the filter media contamination conveyed further in the residue area. The endless woven fabric band running out of the filter pan is cleaned while running by means of a row of blower nozzles 12. The removal of the filtrate is done through a barometric downpipe 13 or a filtrate pump 14. The necessary amount of filtrate for the purpose of sealing is either taken from the Pump pressure line 30 removed from which it can have its own circuit with the pump 15 are provided.

Die einwandfreie Vakuumdichtigkeit der endlosen Förderkette mit Querstäben und Webstoffband gegen den Filtratraum wird wie nachfolgend beschrieben erreicht: An den beiden Längskanten ist gemäß F i g. 2 der Webstoff 18 an ein Abdichtband 19, z. B. Nylonriemen, angeschlossen. Dieser kann, als eine der möglichen Befestigungsarten, durch Schrauben 20 an den Stäben des Kettenrostes 8 befestigt und bei Bedarf zusätzlich durch Blattfedern 21 auf die Gleitfläche 22 gedrückt werden. Bei eventuell vorhandenen Undichtigkeiten zwischen Abdichtband und Gleitfläche kann durch Löcher 23 aus den Räumen 24 Filtrat angesaugt werden, welches den Spalt abdichtet und in den Filtratraum zurückfließt. Dieses Filtrat wird über Abzweigung der Druckleitung 30 oder durch Pumpe 15 nach Bedarf in die Räume 24, welche an beiden Seiten des Ein- und Auslaufes angeordnet sind, nachgefördert. The perfect vacuum tightness of the endless conveyor chain with cross bars and woven fabric tape against the filtrate space is achieved as described below: According to FIG. 2 the woven fabric 18 to a sealing tape 19, e.g. B. nylon straps connected. This can, as one of the possible types of attachment, fastened by screws 20 to the bars of the chain grate 8 and, if necessary, additionally are pressed onto the sliding surface 22 by leaf springs 21. If there are any Leaks between the sealing tape and sliding surface can be through holes 23 from the Spaces 24 filtrate are sucked in, which seals the gap and into the filtrate space flows back. This filtrate is branched off the pressure line 30 or through Pump 15 as required into the rooms 24, which are on both sides of the inlet and outlet are arranged, funded.

Am Einlauf und Auslauf des Filterbandes in den wannenförmigen Rückstandsraum3 erfolgt die Ab- -dichtung in Querrichtung gemäß F i g. 3 und 4 durch das Filtrat, welches in die Räume 25, begrenzt durch zwei Stäbe des Kettenrostes 8, das Gleitblech 26, die Kette 7, das Abdeckblech 27, das Webstoffband 18 und das Führungsprofil 28, gelangt und dem natürlichen sowie dem Druckgefälle folgend durch die Schlitze zwischen den Kettenroststäben und dem Gleitblech von Kammer zu Kammer bis zum Filtratraum fließt, wobei die Gesamtdruckverluste in den Spalten gleich oder größer als das anstehende Vakuum im Filtratraum sind. Falls das zu diesem Zweck erforderliche Filtrat, welches durch die Filterfläche der schiefen Ebene der Wanne fließt, nicht ausreicht, wird zusätzlich Filtrat aus den Räumen 24 über die Löcher 23 an der Kettenführung automatisch angesaugt. Eventuell in Förderrichtung des Bandes aus den Räumen 25 mitgeführtes Filtrat fließt in Rinne 29 und über eine Schleuse in den Filtratraum oder in den Aufgaberaum zurück. At the inlet and outlet of the filter belt in the tub-shaped residue space 3 the sealing takes place in the transverse direction according to FIG. 3 and 4 through the filtrate, which in the spaces 25, limited by two bars of the chain grate 8, the sliding plate 26, the chain 7, the cover plate 27, the woven fabric tape 18 and the guide profile 28, and following the natural as well as the pressure gradient through the slots between the chain grate bars and the sliding plate from chamber to chamber to the filtrate chamber flows, with the total pressure drops in the columns equal to or greater than that pending vacuum in the filtrate space. If the filtrate required for this purpose, which flows through the filter surface of the inclined plane of the tub is not sufficient, is also filtrate from the spaces 24 via the holes 23 on the chain guide automatically sucked in. Possibly in the conveying direction of the belt from rooms 25 Entrained filtrate flows into channel 29 and through a lock into the filtrate space or back to the dispatch room.

Außerdem ist durch Beheizung des unter Vakuum stehenden Filtratraumes 9 eine Entgasung oder durch an der Filterwanne 16 vorzusehende Kühlilächen 17 eine Kühlung des Filtrates möglich. In addition, the filtrate chamber, which is under vacuum, is heated 9 degassing or through cooling surfaces 17 to be provided on the filter trough 16 Cooling of the filtrate possible.
