Abstract

To separate concentrated solids from liquids, for their removal, the soiled liquid is collected in a hollow cylindrical separation zone between a cylindrical vibrator and a cylindrical sieve. Air bubbles are introduced directly before or during the separation action to carry the solids upwards, and any collected matter is scraped from the sieve. The assembly to separate concentrated solids from liquids has porous units (9) of sintered metal at the base (8) of the vibration filter, to give a fine distribution of compressed air into the separation zone (3) of the filter. Or the air is formed into micro-bubbles assisted by cavitation. In the separation zone, the solid matter clings to the bubbles, to be detached from the inner surface of the sieve (7) by a rotating scraper (15), powered by a motor (16) through a drive ring (17).

Description

Anwendungsgebietfield of use

Die Aufarbeitung und Rezirkulation von Produktions- und Abwässern aus verschiedenen Bereichen und Industriezweigen mit dem Ziel der sparsamen Verwendung von Wasser gewinnt immer mehr an Bedeutung.The processing and recirculation of production and waste water different areas and industries with the aim of economical Use of water is becoming increasingly important.

Besonders im Bereich der Papierindustrie werden durch die immer größere Rezirkulierung von Altpapier die Fasern immer kürzer, so daß die Abscheidung derselben aus den Wasserkreisläufen immer schwieriger wird.Especially in the paper industry, the larger and larger Recirculation of waste paper keeps the fibers shorter, so that the separation the same becomes increasingly difficult from the water cycles.

Die Erfindung bezieht sich daher auf die Verbesserung eines Vibrationsfeinfilters zur Fest-Flüssig-Trennung, mit dessen Hilfe von Grobstoffen gereinigte Flüssigkeiten weiter von feinen Feststoffanteilen befreit werden können.The invention therefore relates to the improvement of a vibration fine filter Solid-liquid separation, with the help of coarsely cleaned liquids can be freed from fine solids.

Die in diesen Geräten zur Anwendung kommenden Loch- bzw. Spaltweiten liegen im Bereich von 0,02-0,2 mm.The hole or gap widths used in these devices are in the Range of 0.02-0.2mm.

Ziel ist, die Verbesserung eines kontinuierlichen und störungsfreien Austrages der aufkonzentrierten Feststoffe aus dem Filter.The aim is to improve the continuous and trouble-free discharge of the concentrated solids from the filter.

Charakterisierung der bekannten technischen LösungenCharacterization of the known technical solutions

In der deutschen Patentanmeldung Akz.: 199 39 338.9 wurde ein Vibrationsfeinfilter dargestellt, in dem durch senkrechtes Anlegen und Abheben der Feststoffteilchen vom Sieb im Rhythmus der Schwingung und durch die freie Beweglichkeit des zylindrischen Vibrators innerhalb des etwas größeren, fest eingespannten, zylindrischen Siebes und durch die kreisende Veränderung der Breite des Ringspaltes die Flüssigkeit in eine im Ringspalt rotierende Bewegung versetzt wird. Das Abfließen der sich abscheidenden Flüssigkeit durch das Sieb konzentriert die leichten Feststoffe im oberen Bereich und schwereren im unteren Bereich auf. Sie werden von dort kontinuierlich abgeleitet.In the German patent application Akz .: 199 39 338.9 a vibration fine filter was used shown in the vertical application and lifting of the solid particles from the sieve in the rhythm of the vibration and through the free mobility of the cylindrical vibrator within the slightly larger, firmly clamped, cylindrical sieve and by the circular change in the width of the Annular gap the liquid is set in a rotating movement in the annular gap. The outflow of the separating liquid through the sieve concentrates the light solids in the upper area and heavier in the lower area. she are continuously derived from there.

Die Ableitung der aufkonzentrierten leichten Feststoffe als Teilstrom erfolgt durch die Regelung des Zulaufes oder über ein Anstauen des Klarlaufes bis zur Höhe der Überlaufkante.The concentration of the concentrated light solids as a partial flow is carried out by the regulation of the inflow or an accumulation of the clear run up to the amount of Overflow edge.

Schwerere Feststoffe sind aus dem unteren Bereich mit Hilfe eines Ventils kontinuierlich oder diskontinuierlich abzulassen. Heavier solids are from the bottom area with the help of a valve drain continuously or discontinuously.  

Zur Unterstützung dieser Ableitung sind auf dem äußeren Vibratormantel Spiralen angebracht.To support this derivation, spirals are on the outer vibrator jacket appropriate.

Im praktischen Betrieb dieser Maschine zeigt sich aber, daß bei Schwankungen der Konzentration des Feststoffes sich Bereiche im Abscheideraum ausbilden, in denen sich auf dem zylindrischen Sieb Feststoffe in Nestern ansammeln und durch den leicht unterschiedlichen Druck vor und hinter dem Sieb dort festgehalten werden.In practical operation of this machine, however, it turns out that with fluctuations the Concentration of the solid form areas in the separation room in which solids accumulate in nests on the cylindrical sieve and through the slightly different pressure in front of and behind the screen can be held there.

Die Wirksamkeit der auf dem Vibratormantel angebrachten Spiralen reicht in diesem Fall nicht aus, diese Feststoffe zum Austrag hin zu transportieren.The effectiveness of the spirals attached to the vibrator jacket is sufficient in this Do not fail to transport these solids for discharge.

Ziel der ErfindungAim of the invention

Das Ziel der Erfindung ist es, die Bildung von Nestern aus Feststoffen zu verhindern und den kontinuierlichen Transport der aufkonzentrierten Feststoffe zum Austrag hin störungsfrei zu gestalten.The aim of the invention is to prevent the formation of nests from solids and the continuous transport of the concentrated solids to the discharge to design trouble-free.

Außerdem soll erreicht werden, daß durch den gleichmäßig kontinuierlichen Austrag der Grad der Aufkonzentration erhöht und damit die Wirksamkeit des Filters verbessert wird.In addition, it should be achieved that through the evenly continuous discharge the degree of concentration increases and thus the effectiveness of the filter is improved.

Merkmale der ErfindungFeatures of the invention

Erfindungsgemäß wird das Austragen der aufkonzentrierten Feststoffe, die aus feststoffbelasteten Flüssigkeiten sich im hohlzylindrischen Abscheideraum ansammeln dadurch verbessert, daß in die einströmende feststoffbelastete Flüssigkeit oder unmittelbar vor dem Abscheideraum Luftblasen zur Unterstützung der Bewegung der aufkonzentrierten Feststoffe nach oben eingeleitet werden und außerdem durch auf dem Sieb umlaufende Schaber Anhaftungen abgestreift werden.According to the invention, the discharge of the concentrated solids from liquids contaminated with solids accumulate in the hollow cylindrical separation chamber accumulate improved that in the inflowing solids-loaded Liquid or air bubbles immediately in front of the separation room for support the upward movement of the concentrated solids are initiated and also stripped off by scraper revolving on the sieve become.
