Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a sewage sedimentation tank comprises a sedimentation tank body 1, an overflow weir 2 and a drainage weir 3 are sequentially arranged on the top of the sedimentation tank body 1 from the outside to the center, the overflow weir 2 is slightly higher than the drainage weir 3, a filtering ring net 8 is fixedly arranged on the top of the overflow weir 2, and a filtering ring plate 9 is fixedly arranged between the overflow weir 2 and the drainage weir 3, sewage is firstly injected into an annular groove body formed by the overflow weir 2 and the sedimentation tank body 1 until the sewage overflows through the overflow weir 2 and the filtering ring net 8, so as to complete simple scum filtering, then the sewage flows through the filtering ring plate 9 and permeates into the annular groove body formed by the overflow weir 2 and the drainage weir 3, so as to complete simple floccule filtering, until the sewage overflows through the drainage holes of the drainage weir 3 and flows into the sedimentation tank in a centralized manner, the preliminary simple and easy processing of realization to sewage has simultaneously alleviated the water potential that flows into the sedimentation tank, has effectively improved the overall efficiency who subsides.

Referring to fig. 2-5, the column 4 is disposed at the bottom center of the sedimentation tank body 1, and the column body is rotatably provided with the link ring 5, when the sedimentation tank is cleaned, the driving motor 6 drives the bridge arm 7 to rotate, so as to drive the two mud scrapers 10, the two filtering scrapers 11 and the two scum hoppers 12 to rotate synchronously, the mud scrapers 10 scrape and plane the sludge at the bottom of the sedimentation tank, the link ring 5 effectively improves the motion stability of the two mud scrapers 10, the filtering scrapers 11 concentrate and dredge the sediments on the filtering ring plate 9, the scum hoppers 12 collect the scum outside the filtering ring net 8, and the through holes at the tail parts of the scum hoppers 12 are used for filtering water, which are performed synchronously, thereby facilitating the subsequent centralized processing and effectively saving the cleaning cost.

The working principle is as follows: the utility model discloses when using, sewage at first pours into the annular cell body that overflow weir 2 and sedimentation tank body 1 constitute into, filters through filtering looped netowrk 8 and filtering crown plate 9 in proper order, accomplishes sewage and simply filters the back, flows into the sedimentation tank through the drainage hole of drainage weir 3 again, and the rivers trend that gets into in the sedimentation tank is alleviated greatly, is favorable to improving the efficiency of subsiding.
