When following, floating catch basin level is parked on the extreme lower position position-limited rack of floating catch basin.When the muddy water warp in sedimentation basin
After the device that seeps water empties, start precipitating sludge and draw device progress sludge clearing clearly.
Start the first screw conveyor and rotary drive mechanism successively, rotary drive mechanism drives small scraper plate by prescribed direction
Sludge scraping above small scraper plate is entered sludge collecting chamber and passes through the first helical feed by mechanism and the rotation of big scraping plate mechanism, small scraper plate
Sludge is transported to outside pond by machine, after treating that sludge above small scraper plate is peace and quiet, starts big scraper plate up and down motion driving mechanism, is made big
Scraper plate is moved down by certain speed, and big scraper plate is scraped sludge layer by layer into above small scraper plate, and small scraper plate is again by top
Sludge scraping, which enters sludge collecting chamber and passes through the first screw conveyor, is transported to sludge outside pond, when big scraper plate scraping blade is close to small scraper plate
When, big scraper plate is withdrawn into below water outlet fixing pipe close to water outlet fixing pipe by big scraper plate up and down motion driving mechanism reverse operation
Place.
The valve on sedimentation basin raw water water inlet pipe is opened, after precipitation pool water level reaches extreme higher position and clear water zone water is clear,
Water outlet fixing pipe outlet valve is opened, sedimentation basin is put into operation again.
If cleared out sludge out of sedimentation basin in sedimentation basin operational process, need to use the second spiral
Second screw conveyor entrance with the outlet of the first screw conveyor is docked, is used in combination first by conveyer mouth to mouth
Screw conveyor and the second screw conveyor carry out sludge cleaning.
In sedimentation basin operational process, when sludge blanket height reaches setting height, start the second screw conveyor, successively
One screw conveyor and rotary drive mechanism operation and big scraper plate up and down motion driving mechanism, pond is discharged by sludge out of sedimentation basin
Outside.When sludge blanket height drops to setting height, driving mechanism of stopping rotating successively, the first screw conveyor and the second spiral transferring
Machine is sent to run.
Compared with prior art, the present invention is easy to operate, is directly squeezed using the self gravitation effect for the sludge that loses flowability
Pressure sludge makes sludge dewatering, then sludge is delivered to outside sedimentation basin by drawing device clearly.
