Abgesteifter Filtersack. Patentiert im Deutschen Reiche vom 5. November 1908 ab.Stripped filter bag. Patented in the German Empire on November 5, 1908.
Sackfilter haben den Vorzug, daß man sie im Verhältnis zu ihrem Querschnitt sehr lang machen kann, um dem zu filtrierenden Stoff eine große Oberfläche darzubieten. Derartige lange Sackfilter haben aber den Nachteil, daß sie sich unter dem Druck der Flüssigkeit sehr ungleich ausbauchen- Man hat sie deshalb in geschlossenen Käfigen aus Drahtgaze, Stäben oder Behältern mit durchbrochenen Wänden anderer Art untergebracht. Dadurch wird aber die Filtereinrichtung schwerfällig und unzugänglich.Bag filters have the advantage that they are very long in relation to their cross-section can make in order to present the substance to be filtered a large surface. Such long bag filters have the disadvantage that they are very much under the pressure of the liquid They bulge out unevenly - they are therefore kept in closed cages made of wire gauze, rods or containers with perforated walls of another type housed. This will but the filter device clumsy and inaccessible.
Nach vorliegender Erfindung soll nun zum Absteifen des Filtersackes dieser mit einem Gestell umgeben werden, das aus einzelnen Stäben besteht, die leicht lösbar miteinander verbunden sind.According to the present invention is now to stiffen the filter bag with a Frame are surrounded, which consists of individual rods that are easily detachable from each other are connected.
Die Erfindung ist in beiliegender Zeichnung dargestellt, und zwar zeigt:The invention is shown in the accompanying drawing, which shows:
Fig. ι die Ansicht,Fig. Ι the view,
Fig. 2 einen Grundriß eines derartigen Filtersackes. Fig. 2 is a plan view of such a filter bag.
Der Filtersack α ist in bekannter Weise an einem Rohrstutzen b aufgehängt, und es wird ihm der zu filtrierende Stoff durch einen Hahn c zugeführt.The filter bag α is suspended in a known manner from a pipe socket b , and the substance to be filtered is fed to it through a tap c.
Das Stabgestell besteht aus vier T - förmig gestalteten Stäben d, die oben und unten hakenförmige Enden e und f besitzen. Mit den oberen Hakenenden e werden sie an einem Flansch des Rohrstutzens' aufgehängt, während die unteren Enden zur Aufnahme eines Ringes g dienen, der nach Zusammendrücken der Stäbe übergeschoben werden kann und ihre Bewegung nach außen hin begrenzt.The rod frame consists of four T-shaped rods d, which have hook-shaped ends e and f at the top and bottom. With the upper hook ends e they are suspended from a flange of the pipe socket ', while the lower ends serve to receive a ring g , which can be pushed over after the rods are compressed and limits their movement to the outside.
Ein derartiges Stabgestell ist offenbar leicht lösbar, da jeder Stab um das obere Hakenende gedreht oder auch ganz ausgehängt werden kann. Der T-förmige Querschnitt der Stäbe bietet dem inneren Druck des Filters den erforderlichen Widerstand. Andererseits aber bieten die Flanschen der Stäbe dem ausgebauchten Filtersack gute Anlageflächen, welche den Ablauf des Filtrates an den Stäben entlang begünstigen.Such a rod frame is evidently easily detachable, since each rod around the upper end of the hook can be rotated or completely unhooked. The T-shaped cross-section of the rods offers the internal pressure of the filter the required resistance. On the other hand, the flanges of the bars offer that The bulging filter bag has good contact surfaces, which allow the filtrate to run off on the rods favor along.
Wird der Filtersack mit Längsnähten bei h versehen, so kann man diese zwischen den Stäben heraustreten lassen und hat an ihnen eine geeignete Handhabe, um die Lage des Filtersackes zu regeln.If the filter bag is provided with longitudinal seams at h , these can be let out between the rods and a suitable handle can be used on them to regulate the position of the filter bag.
Derartig versteifte Filtersäcke nehmen im Verhältnis zu ihrer Filterfläche einen sehr geringen Raum ein und gestatten eine dichte Aneinanderreihung von Filtersäcken zu einer Gruppe, da ihr Querschnitt durch das Stabgestell begrenzt bleibt.Such stiffened filter bags take a lot in relation to their filter surface small space and allow a close stringing together of filter bags to form one Group, as its cross-section remains limited by the rod frame.
Es ist aber auch möglich, derartig abgesteifte Sackfilter sehr lang, d. h. von großer Filterfläche bei kleinem Querschnitt · herzustellen, und dies ist für einen gleichmäßigen Absatz der Filterrückstände an den Wänden der Säcke von wesentlicher Bedeutung. But it is also possible to make such stiffened bag filters very long, d. H. from large filter surface with a small cross-section · and this is for a uniform Paragraph of the filter residue on the walls of the bags is essential.
