KLASSE 58: Pressen.CLASS 58: Pressing.
Die gebräuchlichen, gerillten Platten bei Filterpressen haben den Nachtheil, dafs die darauf aufgeschraubten Siebbleche, die .hinter denselben befindlichen Rillen, sowie die kleinen Kanäle, welche das Innere der Presse mit den Hauptkanälen oder mit der äufseren Luft verbinden, leicht inkrustirt werden, wenn die zu filtrirende .Flüssigkeit geneigt ist, feste Substanzen abzusetzen oder wenn die Filtertücher porös sind und Schlamm durchlassen. Als Flüssigkeiten, welche gern Inkrustationen bilden, sind die Säfte in Rohzuckerfabriken, besonders aber Laugen in Melasse - EnI-zuckerungsanstalten bekannt.The usual, grooved plates in filter presses have the disadvantage that the Sieve plates screwed onto it, the grooves located behind the same, as well as the small channels which connect the inside of the press with the main channels or with the outer one Combine air, become easily encrusted if the liquid to be filtered is inclined, solid Settle substances or if the filter cloths are porous and allow sludge to pass through. As liquids that tend to form incrustations, the juices are in raw sugar factories, but especially lyes in molasses - EnI sugar plants known.
Haben nun derartige Inkrustationen stattgefunden, so ist die Filterpresse ganz oder zum Theil betriebsunfa'hig, denn es ist klar, dafs dieselbe keine Flüssigkeit filtriren kann, wenn nicht das Filtrat frei ablaufen kann, und dafs sie in ihrer Leistungsfähigkeit beschränkt wird, wenn der Ablauf des Filtrats mit Schwierigkeiten verknüpft ist. Das Reinigen der inkrustirten Kammern ist eine sehr mühsame und kostspielige Arbeit, die jedesmal, wenn sie mitten im Betriebe nöthig wird, denselben ganz erheblich stört. Die nachfolgend beschriebene Einrichtung soll diesem Uebelstande abhelfen.If such incrustations have now taken place, the filter press is wholly or partly inoperable, for it is clear that it cannot filter any liquid, if not that The filtrate can run off freely, and that its efficiency is limited if the Drainage of the filtrate is associated with difficulties. The cleaning of the encrusted Chambers is a very tedious and costly job that is performed every time it is in the middle becomes necessary in the enterprise, disturbs it quite considerably. The one described below Facility is intended to remedy this disadvantage.
Die Filterplatten (Kammern) werden nicht, wie die oben beschriebenen, in Form massiver, verschieden modellirter Platten gegossen, sondern sollen nur aus Rahmen [α α der Zeichnung), ganz ähnlich den jetzt schon verwendeten Rahmen, bestehen, in welche an Stelle des gerillten und mit Siebblech überdeckten mittleren Theiles besondere kastenförmige Filtrireinsätze b b befestigt werden.The filter plates (chambers) are not cast in the form of massive, differently modeled plates, as described above, but should only consist of frames (α α of the drawing), very similar to the frames already used, in which instead of the grooved one and special box-shaped filter inserts bb are attached to the middle part covered with a sieve plate.
Diese Filtrireinsätze bestehen aus Siebblechen oder Drahtsieben, welche in bestimmter Entfernung gehalten und versteift werden. Dies kann durch zwischen ihnen angebrachte Flachoder andere Profileisen c c. und d d (wie gezeichnet), durch Stehbolzen oder auch durch wellenförmige Bleche erreicht werden. Die Einsätze können auch aus anderem Material, als Eisen, hergestellt sein.These Filtrireinsätze consist of sieve plates or wire screens, which are held at a certain distance and stiffened. This can be achieved by means of flat or other profile iron c c. and dd (as shown) can be achieved by stud bolts or by corrugated metal sheets. The inserts can also be made of a material other than iron.
Der so hergestellte Einsatz b b bietet für den Abflufs des Filtrates einen gröfseren, freien Raum, als die Rillen der jetzt üblichen Filterprefskammern. Die Inkrustirung und Verschlammung derselben wird daher erst nach viel längerem Gebrauch, als bei den bisherigen Kammern, eintreten und störend wirken; wenn aber der Zeitpunkt eingetreten ist, dafs die Löcher der Siebbleche oder die Eintritts- oder Ablauf kanälchen verstopft sind, so kann dem Uebelstand leicht und ohne erhebliche Kosten abgeholfen werden. Die Filtereinsätze werden einfach aus ihren Rahmen herausgenommen und durch neue Einsätze ersetzt. The insert bb produced in this way offers a larger, free space for the filtrate to drain off than the grooves of the now usual filter pre-chambers. The encrustation and silting up of them will therefore only occur and have a disturbing effect after much longer use than in the previous chambers; but when the time has come that the holes in the sieve plates or the inlet or outlet canals are clogged, the problem can be remedied easily and without considerable costs. The filter inserts are simply removed from their frames and replaced with new inserts.
Das Reinigen der inkrustirten Einsätze kann leicht und billig geschehen. Bei Kalkinkrustationen werden sie einfach in Salzsäure ausgespült und dann mit Wasser oder Sodalösung wieder von der Säure befreit. Wenn man dieThe encrusted inserts can be cleaned easily and cheaply. With calcium incrustations they are simply rinsed in hydrochloric acid and then freed from the acid again with water or soda solution. If you have the
bisherigen, gufseisernen Kammern in derselben Weise behandeln wollte, so würde man dieselben insofern beschädigen, als die bearbeiteten Dichtungsflächen durch die Säure zerfressen werden, die Pressen also nachher nicht mehr dicht halten.previous cast iron chambers in the same If you wanted to treat them wisely, you would damage them insofar as they worked on them Sealing surfaces are eaten away by the acid, so the presses no longer afterwards hold tight.
