Description

Verfahren zum Betrieb eines Eindickers Zusatz z Patent 858 539 In der Patentschrift 858 539 ist ein Verfahren zum Betrieb eines kontinuierlich arbeitenden Eindickeres beschrieben, bei dem sich in dem Schlammbehälter ein Filterkörper befindet, durch den vermittels eines Druckunterschiedes auf beiden Seiten des Filtermediums die Trennung der festen und flüssigen Phase vorgenommen wird. Durch eine Qübrwirkung auf der Schlammseite des Filtermediums oder durch Bewegen des Filtermediums durch Filtratstöße, Ultraschallwellen u. ä. von innen wird die Kuchenbildung verhindert oder die Kuchenstärke in einer die Filtration hemmenden Stärke vermieden.Method of operating a thickener addendum z patent 858 539 In the Patent specification 858 539 is a method of operating a continuously operating Thickener described, in which there is a filter body in the sludge container, by means of a pressure difference on both sides of the filter medium the solid and liquid phases are separated. Through a crossover on the sludge side of the filter media or by moving the filter media through Filtrate surges, ultrasonic waves, etc. from the inside prevent cake formation or the cake starch in a filtration inhibiting starch avoided.

Es hat sich gezeigt, daß bei mancllen Stoffen das Ansetzen des Filterlsuchens besonders dann sehr wirksam unterbunden werden kann, wenn man die Druckdifferenz nicht dauernd in gleicher Höhe hält, sondern intermittierend entweder diese ganz aufhebt oder wenigstens vermindert, wobei diese Änderung nicht über die ganze Filterfläche gleichzeitig zu erfolgen braucht. It has been shown that the beginning of the filter search for some substances especially can be prevented very effectively if you consider the pressure difference does not keep constant at the same level, but intermittently either holds it completely cancels or at least reduces, this change not over the entire filter surface needs to take place at the same time.
