APPARATUS FOR PREVENTING CHAMBER HOLE OF SETTLING TANK FROM CLOGGING

摘要

PURPOSE: An apparatus for preventing chamber hole of settling tank from clogging is provided, which can previously efficiently prevent any clogging of chamber hole by installing chamber hole opening device at rotational body that reciprocally moves in chamber space caused by periodical contacts of scrapper arm. CONSTITUTION: In the device for preventing clogging of chamber hole(34) formed at bottom part of the outer chamber(30) to discharge water, after coagulation treatment, to a settling tank, comprised are a rotational body(40) positioned at the base of a space(32) formed between the inner and outer chambers(30,32); an actuating means(60) vertically connected to one position of the rotational body(40) and pivoted to the outer chamber wall for reciprocating the rotational body(40) when it is in contact with a scrapper arm(42); and a hole opening means(80) equipped with a plurality of hole opening rolls(82) installed along the rotational body(40) to pass through the chamber hole(34).
