Zusatz zum Patent 258152.Addendum to patent 258152.
Gemäß dem Patent 258152 werden Abwässer gereinigt sowie "die ausgefallenen Schlämme entwässert, indem man ein durch Behandlung von unter Luftabschluß geglühtem Ton,t Bauxit o. dgl. mit Säure und beschränk-* ter Menge Wasser gewonnenes Präparat zusetzt. Gemäß dem Patent 273607 können schlammartige Massen verschiedener Art, insbesondere Abfallfette, Schlempe, Treber usw., in gleicher Weise entwässert werden.According to the patent 258152 waste water is purified and dewatered, the precipitated sludge ", by adding a product obtained by treatment of annealed with exclusion of air clay, t bauxite o. The like. With acid and beschränk- * ter amount of water preparation. According to the patent 273607 can mud-like Masses of various types, in particular waste fats, stillage, spent grains, etc., are dewatered in the same way.
Es wurde gefunden, daß diese Behandlung vorteilhaft auch auf Ton- und Kaolinschlämme Anwendung finden kann, und zwar zum Zwecke einer gründlichen Ausscheidung der sandigen Bestandteile und zur Gewinnung der Tonsubstanz in einem Zustande von innigem Massenzusammenhalt und erhöhter Adsorptionsfähigkeit. It has been found that this treatment is beneficial also on clay and kaolin slurries Can be used, for the purpose of a thorough excretion of the sandy components and for the extraction of Clay substance in a state of intimate mass cohesion and increased adsorptive capacity.
Hochfeinverteilte, sogenannte plastische Tone oder Kaoline besitzen gleichfalls kolloidale Eigenschaften, indem ein gewisser Prozentsatz ihrer Masseteilchen, wie andere pseudogelöste Stoffe, in Wasser verteilt, kolloidal gelöst erscheinen. Diese Ansicht wird dadurch als richtig erwiesen, daß diese kolloidal aufgeschwemmten anorganischen Teilchen ebenso koagulationsfähig sind wie beispielsweise organische, im Wasser schwebende Kolloide; denn sie flocken bei Untermischung mit dem nach dem Patent 258152 hergestellten, gallertartige Kieselsäure und Aluminiumsulfat enthaltenden Präparate aus. Die kolloidale Eigenschaften besitzenden Tonteilchen schließen sich hierbei zu feinflockigen Massenteilchen zusammen, während die körnigen oder sandigen, solche Eigenschaften nicht besitzenden Teilchen des Tones hierzu nicht fähig sind und daher für sich und wegen ihres größeren spezifischen Gewichtes schnell zu Boden fallen.Very finely distributed, so-called plastic clays or kaolins also have colloidal ones Properties by having a certain percentage of their mass particles, like other pseudo-dissolved Substances, dispersed in water, appear to be colloidally dissolved. That view is then called Properly proved that these colloidally suspended inorganic particles do the same Are capable of coagulation, such as, for example, organic colloids suspended in water; because they flocculate when mixed with the gelatinous produced according to patent 258152 Preparations containing silica and aluminum sulphate. The colloidal properties Owning clay particles combine to form fine flaky mass particles, while the granular or sandy particles do not possess such properties Tones are not capable of this and therefore for themselves and because of their greater specificity Weight fall to the ground quickly.
Das Verfahren wird beispielsweise derart ausgeführt, daß man Kaolin oder Ton in. Wasser aufschlämmt und mit der genannten kieselsäurehaltigen Masse sowie vorteil- , haft etwas Kalkmilch oder Kalkwasser, um die Säure abzustumpfen, innig vermischt und dann unter weiterem Zufluß von Wasser ein Klärbecken durchfließen läßt, dessen Boden hintereinander angeordnete trichterförmige Vertiefungen enthält. In dem ersten dieser Trichter fallen sofort die sandigen und körnigen Bestandteile aus, beim Fortschreiten des Durchfließens dann ■— sich nach ihrem spezifischen Gewichte zeitlich trennend — die schwereren Flocken schneller, leichtere langsamer aus, so daß also auf diesem einfachen Wege eine Schlämmung und zugleich Trennung in mehrere Feinheitsgrade stattfindet. Auf diese Weise gelingt es, das Vielfache der bisherigen Schlämmverfahren zu leisten und beispielsweise mittels eines nur 5 m langen, etwa I1Z2 m breiten Klärbeckens innerhalb 24 Stunden etwa 9000 bis 10 000 kg feinst geschlämmten Kaolin herzustellen und durch Filterpressen oder Schleuderung zu entwässern.The process is carried out, for example, by slurrying kaolin or clay in water and thoroughly mixing it with the said silicic acid-containing mass and, advantageously, some milk of lime or lime water to blunt the acid, and then allowing a clarifier to flow through a clarifier with further influx of water , the bottom of which contains funnel-shaped depressions arranged one behind the other. In the first of these funnels the sandy and granular components fall out immediately; as the flow progresses, the heavier flakes fall out faster, lighter flakes, slowly separating according to their specific weight, so that in this simple way a slurry and separation at the same time takes place in several degrees of fineness. In this way, it is possible to achieve a multiple of the previous sludge processes and, for example, using a clarifier only 5 m long, about I 1 Z 2 m wide, to produce about 9,000 to 10,000 kg of finely slurried kaolin within 24 hours and to dehydrate it by filter pressing or centrifugation .
