during the silt clearance, to the inside clearance of collection box 11, control valve 33 rotates, first connecting pipe 34 communicates with sludge pump 32, send the mud in the collection box 11 into centrifugal sludge separating centrifuge 31 and separate, the separation water gets into in the third sedimentation tank, first sedimentation tank is the same with second sedimentation tank clearance silt principle, its difference lies in, first sedimentation tank and second sedimentation tank need carry out the reposition of redundant personnel with the supernatant before clearance silt and handle, drive closure plate 26 through the lead screw and remove, make filter 23 from top to bottom progressively open, its maximum degree of opening should be higher than the height of silt, the clearance order is first sedimentation tank behind the first second sedimentation tank.
The recovery device can continuously clean the insoluble substances in the domestic sewage to achieve the primary separation of the insoluble substances from the sludge water, and then the precipitated sludge is separated by the centrifugal sludge separator to realize the multi-stage sludge treatment; the filter screen of alternating work collects the undissolved substance when filtering sludge water to send conveying piece and see off the undissolved substance, reduce staff intensity of labour, improve separation efficiency, the effectual dirt to the filter screen deposit of clearance piece is cleaned and is prevented that the filter screen from blockking up, and the sedimentation tank has multistage subsides, can the automatic mud of clearance of efficient to the more first sedimentation tank of mud and second sedimentation tank.
