Zusammenfassung: | The installation relates to a submersible installation for discharging the sludge, used in the secondary settling basins of the local and industrial waste water purifying installation The installation comprises a conduit (1) for sludge transport, submersibly rolling under the action of a driving unit (6), said conduit being provided with a float (10) for preventing its bending under its own weight, and with some suction holes (9) taking the sludge discharged from the conduit (1) through a pleating-tube (16) to an annular chamber (17) built all around the central pivot of the settling tank by means of a cylindrical casing (18) and sealed by means of a labyrinth gland (19) so that, during the rolling of said conduit in the chamber, only the sludge entering the suction holes (9) is sucked The discharge of the sludge from the conduit (1) is performed by siphoning through a siphon trap (21) in a collection vessel (22) linked to the sludge discharge conduit of the sludge to prevent sliding during winter time, the driving unit (6) operating by means of wheel chain (8), rolling gear (5) being mounted either at the bottom of the basin or respectively on top of the basin walls |
