AGITATOR-CLEANING WASTE LIQUID TREATMENT DEVICE AND TREATMENT METHOD

摘要

PROBLEM TO BE SOLVED: To reduce installation cost and facilitate maintenance services by charging a cleaning liquid consisting of a concrete stabilizer into an agitator and preventing a concrete from sticking to the inner face of the agitator to significantly cut the consumption of water required for cleaning the agitator and minimize the volume of a tank. SOLUTION: The agitator-cleaning waste liquid treatment device 1 is a device for treating a waste cleaning liquid 10 to be discharged from an agitator 9 using a method for cleaning the agitator 9 by which a cleaning liquid consisting of a concrete stabilizer is charged into the agitator 9 and thereby a concrete is prevented from sticking to the inner face of the agitator 9. A recovery chute 2 has an upper face opening 12 for recovering the waste cleaning liquid 10 to be discharged from the agitator 9 and also has an unloading aperture 13 formed at the bottom which is connected to a loading aperture 14 of a carrying drum conveyor 3. The waste discharge 10 passing through a stripping process is separated into aggregates 11 and a mixed liquid of sludge and the cleaning liquid according to a particle dia. by means of a trommel 4.
