Vorrichtung zur Abführung von Schlamm aus Absitzbecken.
EMI1.1
das zu klärende Wasser eintritt, macht sich der Umstand unangenehm bemerkbar, dass der abgeschiedene Schlamm nicht ohne Betriebsstörung entfernt werden kann, weil er entweder gar nicht oder nur nur bei ausserordentlich starker Neigung der Sohle auf dieser abwärts gleitet.
Dies rührt in den meisten Fällen-ausser von der Adhäsion an der Gleitfläche- hauptsächlich daher, dass der Unterschied zwischen dem spezifischen Gewicht des Schlammes und demjenigen der Flüssigkeit, worauf die Sedimentierung oder Aufbereitung beruht, zu

wünscht wird. In ihre tiefste, das ist nächste Lage umgelegt, bilden diese etwas übereinander greifenden Platten eine ununterbrochene Abdeckung für die Längsvertiefung oder den unteren Teil des Heckenraumes.
Je nach der relativen Menge, dem spezifischen Gewicht oder anderen physikalischen Eigenschaften des Schlammes und je nach der Grösse des Neigungswinkels der Sohlenvertiefung, welche Verhältnisse für die Geschwindigkeit der Eigenbewegung des Schlammes
EMI1.4
An Stelle des Systems kleiner Platten können je nach der Grösse des Beckens oder der Art des Schlammes usw. ganz oder teilweise bewegliche Kanalteile beliebiger Form. wie in Fig. 2 und 3 angedeutet, verwendet werden.

Device for removing sludge from settling basins.
EMI1.1
If the water to be clarified enters, the fact that the separated sludge cannot be removed without operating disruptions becomes unpleasant because it either does not slide down at all or only when the sole is extremely inclined.
In most cases - apart from the adhesion to the sliding surface - this is mainly due to the difference between the specific weight of the sludge and that of the liquid on which the sedimentation or processing is based
EMI1.2
In the embodiment shown in FIG. 1, one or more rows are arranged above one or more depressions, preferably running in the longitudinal direction of the hedges.
EMI1.3
wishes is. In their deepest position, which is the next layer, these slightly overlapping plates form an uninterrupted cover for the longitudinal recess or the lower part of the hedge area.
Depending on the relative amount, the specific weight or other physical properties of the mud and depending on the size of the angle of inclination of the sole recess, what ratios for the speed of the self-movement of the mud
EMI1.4
Instead of the system of small plates, depending on the size of the basin or the type of sludge, etc., fully or partially movable channel parts of any shape can be used. as indicated in Figs. 2 and 3 can be used.
