after entering the tank body I101 from the water inlet pipe 1011, the sewage mixed with the flocculant enters the lower part of the tank body I101 for precipitation through the guidance of the baffle I102, the baffle II 103 and the baffle III 104; after the sedimentation is finished, the upper layer clear sewage flows into the tank body II 201 through the connecting pipe 1012, is guided into the bottom of the tank body II 201 through the baffle IV 2011 and one side of the connecting box 206 for sedimentation, the water at the other side of the baffle IV 2011 and the connecting box 206 enters the connecting box 206 after residual particles are filtered by the filter screen 204, and finally enters the subsequent treatment equipment for other treatment through the water outlet pipe 2012; the filter screen 204 filters sewage and simultaneously starts the motor I202 to enable the half gear 205 to control the rack 2051 to squeeze the spring 2052, meanwhile, the rack 2051 is meshed with a gear on the brush plate 203 to control the brush plate 203 to rotate, and after the half gear 205 rotates to one side without gear teeth, the spring 2052 pushes the rack 2051 to control the gear on the brush plate 203 to drive the brush plate 203 to reset, so that the brush plate 203 can reciprocally rotate to clean the filter screen 204; when sewage enters the sedimentation tank I1 and the sedimentation tank II 2, the hydraulic cylinder 3031 withdraws the control connecting rod 3071 to pull the connecting seat II 307 downwards, so that the connecting seat II 307 pulls the scraping plate II 302 to incline inwards through the connecting rod 3021, and meanwhile, the motor III 306 is started to drive the rotating seat 305 to control the scraping plate II 302 to serve as a stirring paddle to rotate so as to fully mix the sewage with the flocculating agent; after the stirring is finished, the hydraulic cylinder 3031 is controlled to extend, so that the connecting rod 3071 pushes the connecting seat II 307 to control the connecting rod 3021 to drive the scraping plate II 302 to reset; when the sewage is deposited, the motor III 306 is started to drive the rotating seat 305 to control the scraping plate I301 and the scraping plate II 302 to rotate so as to scrape the sludge adhered to the inner walls and the bottom of the sedimentation tank I1 and the sedimentation tank II 2, and meanwhile, the sludge scraped by the scraping plate I301 enters the sewage draining mechanism 304 through the rotating seat 305, so that the motor II 3044 controls the spiral blade 3045 to send the sludge into the sludge treatment equipment.
The foregoing is merely illustrative and explanatory of the utility model, as it is well within the scope of the utility model as claimed, as it relates to various modifications, additions and substitutions for those skilled in the art, without departing from the inventive concept and without departing from the scope of the utility model as defined in the accompanying claims.
