[0026] like Figure 1-Figure 3 As shown together, the utility model provides an environmentally friendly sewage treatment system, including a housing 1, wherein a flocculation stirring chamber 2 and a sedimentation chamber 3 are arranged vertically inside the housing 1, and a communication port is provided between the flocculation stirring chamber 2 and the sedimentation chamber 3, and a solenoid valve 19 is installed at the communication port. The solenoid valve 19 is used to control the longitudinal flow of sewage.

[0027] A sewage inlet 4 and a drug addition port 5 are provided on the top of the flocculation stirring chamber 2 .

[0028] A mud discharge port 16 is provided at the bottom of the sedimentation chamber 3 , and a clean water outlet 17 is provided at the side of the sedimentation chamber 3 .

[0029] A stirring blade 6 is provided inside the flocculation stirring chamber 2 , and the stirring blade 6 is installed on the bottom end of the hollow outer shaft 7 . The hollow outer shaft 7 is arranged in a vertical direction, and the upper part of the main body of the hollow outer shaft 7 is rotatably installed in a fixed seat 10 , and the fixed seat 10 is installed on the top of the outer shell 1 .

[0030] The top end of the hollow outer shaft 7 is connected to the motor 11 through the bevel gear set 18. The motor 11 is fixed to the fixing seat 10. The motor 11 transmits power to the hollow outer shaft 7 through the bevel gear set 18 to drive it to rotate, thereby achieving efficient dissolution of sewage and flocculant.

[0031] A mud discharge blade 8 is provided inside the sedimentation chamber 3, and the mud discharge blade 8 is installed at the bottom end of the inner shaft 9. The inner shaft 9 is vertically penetrated inside the hollow outer shaft 7. The inner shaft 9 and the hollow outer shaft 7 are coaxially arranged. The top of the hollow outer shaft 7 is rotatably installed in the lifting seat 12, and the lifting seat 12 can drive the hollow outer shaft 7 to perform lifting actions.

[0032] The inner shaft 9 is provided with an external spline 15 , and the hollow outer shaft 7 is provided with an internal spline, and the external spline 15 can mesh with the internal spline.

[0033] After the outer spline 15 descends with the inner shaft 9, the outer spline 15 is meshed with the inner spline, and the hollow outer shaft 7 can transmit power to the inner shaft 9; after the outer spline 15 rises with the inner shaft 9, the outer spline 15 is disengaged from the inner spline, and the hollow outer shaft 7 no longer transmits power to the inner shaft 9.

[0034] The lifting seat 12 is located directly above the fixed seat 10 , and the lifting seat 12 and the fixed seat 10 are connected via an electric telescopic rod 13 and a guide rod 14 .

[0037] The specific working principle of this utility model:

[0038] The sewage to be treated and the flocculant enter the flocculation stirring chamber 2 through the sewage inlet 4 and the dosing port 5; the motor 11 transmits power to the hollow outer shaft 7 and the stirring blade 6 through the bevel gear set 18, and the sewage and the flocculant are efficiently dissolved and mixed. After mixing, the sewage enters the sedimentation chamber 3 through the solenoid valve 19 for sedimentation treatment, thereby achieving the sewage treatment effect of solid-liquid separation. The treated clean water is discharged through the clean water outlet 17, and the sludge is settled at the bottom of the sedimentation chamber 3.

[0039] When the sludge sedimentation reaches a certain thickness, the electric telescopic rod 13 retracts to drive the lifting seat 12 and the inner shaft 9 to descend. After the outer spline 15 descends with the inner shaft 9, the outer spline 15 is meshed and connected with the inner spline. The hollow outer shaft 7 can transmit power to the inner shaft 9 and the mud discharge blades 8. The mud discharge blades 8 discharge the sludge through the mud discharge port 16 during the rotation process to complete the mud discharge. The motor 11 in the utility model can provide power for flocculation stirring as well as for the mud discharge action.
