Based on the aforesaid, it is elementary the top of settling zone be equipped with the cross-section that the end of inlet tube corresponds is curved frid, run through on the frid and be equipped with the delivery port of a plurality of different orientations.

Based on the above, a water distribution net is arranged below the trough plate in the primary settling zone.

The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model has the following advantages:

1. in the utility model, a multistage settling zone and a water collecting zone are sequentially arranged in the tank body, inclined tube filler is arranged in each stage of settling zone, a mud level meter and a mud discharge port are arranged at the bottom of the settling zone, a solenoid valve is arranged at the mud discharge port, the mud discharge port extends to a mud discharge pipe, a mud pump is arranged on the mud discharge pipe, adjacent two stages of settling zones and a final stage settling zone are separated from the water collecting zone by a partition plate, an overflow hole is arranged on the partition plate, and the end of a water inlet pipe extends to the upper part of the primary settling zone; this structural design not only is favorable to carrying out high-efficient sedimentation to sewage and handles, also is convenient for discharge the mud after the sediment simultaneously.

2. The utility model discloses in, through elementary the top of settling zone sets up the cross-section that corresponds with the end of inlet tube and is curved frid, runs through the delivery port that is equipped with a plurality of different orientations on the frid, corresponds in the elementary settling zone the below of frid is equipped with the water distribution net, and this structural design makes falling that the sewage that needs to be handled can be even in the elementary settling zone, is of value to the effect that improves sewage sedimentation treatment.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

In the figure: 1. a tank body; 2. a settling zone; 3. a water collection area; 4. a partition plate; 5. filling the inclined tube; 6. an overflow aperture; 7. a sludge discharge port; 8. an electromagnetic valve; 9. a sludge discharge pipe; 10. a dredge pump; 11. a mud level meter; 12. a water outlet; 14. draining pump; 15. a water inlet pipe; 16. a groove plate; 17. a water distribution net; 18. and a controller.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

Examples
