Referring to fig. 1-5, the present invention provides a technical solution:

a sewage treatment radial sedimentation tank comprises a tank body 1, wherein the bottom surface of the tank body 1 is provided with a water inlet pipe 4 communicated with the interior of the tank body 1, the bottom surface of the tank body 1 is also provided with a sludge discharge pipe 5 communicated with the inner wall of the bottom end of the tank body 1, a rotating plate 3 is arranged at the middle position of the tank body 1, and a pair of symmetrical sludge scraping plates 31 are tightly welded on the bottom surface of the rotating plate 3; the circumference outer wall upper end position of cell body 1 is built and is had overflow plate 2, overflow launder 21 has been seted up in the overflow plate 2, the bottom surface of overflow plate 2 is equipped with outlet pipe 6, outlet pipe 6 communicates with overflow launder 21 each other, set up a plurality of row's cinder notch 22 that are cyclic annular equidistant range on the diapire of overflow launder 21, be equipped with the row's cinder pipe 7 that is linked together with overflow launder 21 in row's cinder notch 22, the close welding has backup pad 32 on the 3 outer walls of rotor plate, the one end close welding that rotor plate 3 was kept away from to backup pad 32 has row's cinder plate 8, row's cinder plate 8 is.

In this embodiment, the distance between the top surface of the overflow plate 2 and the horizontal ground is greater than the distance between the top surface of the tank body 1 and the horizontal ground, so that the overflow groove 21 is not overflowed when the treated sewage enters the overflow groove 21 during sewage treatment, and waste of water resources is avoided.

In addition, set up collection slag groove 81 on the preceding lateral wall of row's cinder notch 8, collection slag groove 81's bottom and overflow launder 21 are linked together, and after long-term sewage treatment, when some remain impurity and enter into overflow launder 21, need utilize row's cinder notch 8 to clear up impurity, collection slag groove 81 can be at the in-process of clearance, collects impurity, ensures the efficiency of remaining impurity clearance.

Furthermore, the side walls of the left and right groove walls of the overflow groove 21 are connected with the balls 82 in a rolling manner, and the balls 82 are in contact with the left and right groove walls of the overflow groove 21, so that the slag discharging plate 8 is smoother when moving in the overflow groove 21, and the impurity cleaning effect is ensured.

Furthermore, the bottom surface of the slag discharge plate 8 is tightly adhered with bristles 83, the bristles 83 are in contact with the bottom groove wall of the overflow groove 21, and the bristles 83 can effectively clean the residual sediment accumulated on the bottom wall of the overflow groove 21 and sweep the sediment to the slag discharge port 22 for discharge.

Furthermore, be equipped with filter screen 62 in the one end that outlet pipe 6 is close to overflow launder 21, and filter screen 62 is level and level mutually with the bottom cell wall of overflow launder 21, and installs valve 61 on the outlet pipe 6, has ensured that impurity can not follow the clarified water after handling and has been located the discharge in outlet pipe 6 altogether, and when carrying out the clearance of remaining impurity, can close outlet pipe 6 through valve 61, further ensures to follow outlet pipe 6 and can not discharge the sewage that has impurity.

Furthermore, the distance between the top groove wall of the slag collecting groove 81 and the horizontal ground is greater than the distance between the top surface of the tank body 1 and the horizontal ground and less than the distance between the top surface of the overflow plate 2 and the horizontal ground, so that in the process of cleaning residual impurities 1, sewage mixed with the impurities cannot be discharged from the overflow groove 21, and the cleanness of the vicinity of the sedimentation tank is ensured.

Furthermore, the corresponding valve 61 is also arranged on the slag discharging pipe 7, not shown in the figure, so that in the usual sewage treatment process, the slag discharging pipe 7 is constantly in a closed state, the clear water is ensured not to be discharged from the slag discharging pipe 7, and the waste of water resources is prevented.

The rotating plate 3 is driven by an external motor, and can simultaneously clean the residual impurities in the overflow tank 21 when cleaning the sludge in the tank body 1.

When the sewage treatment radial sedimentation tank is used, sewage enters the interior of the tank body 1 from the water inlet pipe 4, impurities such as sludge enter the bottom of the tank body 1 along the gradient of the tank bottom and are discharged from the sludge discharge pipe 5, residual impurities enter the overflow groove 21 in the long-term sewage treatment process, at the moment, the valve 61 on the water outlet pipe 6 is closed and the valve 61 on the slag discharge pipe 7 is opened, then, the power supply of an external motor is opened, the rotating plate 3 is driven to rotate by the motor to drive the supporting plate 32 to rotate, the slag discharge plate 8 starts to move along the overflow groove 21, the residual impurities in the overflow groove 21 are acted by the slag collection groove 81 and are accumulated in the slag collection groove 81, when the slag discharge plate 8 moves to the slag discharge port 22, the residual impurities in the slag collection groove 81 can directly enter the slag discharge pipe 7 from the slag discharge port 22 and are discharged, and after the residual impurities are completely cleaned, the power supply of an external motor is turned off, the valve 61 on the water outlet pipe 6 is opened, the valve 61 on the slag discharge pipe 7 is closed, and the sedimentation tank continues to work normally, so that the problem that in actual use, even if a slag baffle plate is used in the flowing process of sewage, a part of impurities still enter the overflow groove, and the impurity treatment is not thorough is solved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
