The utility model relates to the technical field of
sewage treatment, and discloses a plastic washing
sewage treatment device which comprises a
barrel body, a filtering hole is formed in the left end of the
barrel body, an opening is formed in the right side of the bottom of the
barrel body, and a connecting plate is fixedly connected to the position, outside the opening, of the bottom of the barrel body. A discharging barrel is fixedly connected to the lower side of the connecting plate, a rotating shaft is rotationally connected to the middle of the discharging barrel, an
auger is fixedly connected to the outer portion of the rotating shaft, the outer wall of the
auger is tightly matched with the inner wall of the discharging barrel, and a through hole is formed in the outer side of the
auger. According to the
sewage treatment device, impurities fall into the discharging barrel through the opening formed in the bottom, the rotating auger can drive the impurities to be discharged from the discharging opening, the impurities are cleaned in time, the influence on the
sewage treatment efficiency is avoided, and the second motor drives the stirring shaft to rotate and drives the stirring blades to rotate, so that the mixing of the sewage and a precipitator is promoted; and the arranged stirring shaft drives the scraping plate to rotate, so that the inner wall of the barrel body is cleaned, and blockage is avoided.
