The feeding ring is connected with the external flocculant storage tank through a pipeline. The four groups of nozzles distributed in the circumferential direction at the bottom of the feeding ring realize the annular spraying of the flocculant. When the impurity concentration in the sewage is high, the stirring load increases. The circular truncated cone flow guide block in the nozzle can drive the pushing rod to move up and down through the adjusting assembly, thereby changing the cross-sectional area of the water outlet passage of the nozzle. When the flow guide block moves up, the passage becomes wider and the spraying amount increases. When the flow guide block moves down, the passage becomes narrower and the spraying amount decreases. Thus, the dosage of the reagent can be dynamically adjusted according to the impurity concentration of the sewage, avoiding the problems of excessive waste or insufficient flocculation and reducing the processing cost.

The guide disc 72 rotates to drive the top sliding block of the stirring rod 75 to slide along the oval sliding groove 76 at the bottom of the rotating disc 71, so that the two groups of stirring rods 75 move back and forth along the guide groove 73 in a synchronous manner, and the rack 74 on the inner wall of the guide groove 73 is in meshing transmission with the gear 77 on the surface of the stirring rod 75 while the stirring rod 75 moves along the guide groove 73, thereby driving the stirring rod 75 to rotate, so as to realize the compound motion of the synchronous revolution of the two groups of stirring rods 75 around the driving rod 6 and the back-and-forth movement in a radial direction.

[0020] As an embodiment of the present application, the spraying assembly comprises a feeding ring 781 fixedly connected at the bottom center of the guide disc 72, a spray head 782 fixedly connected at the bottom of the feeding ring 781, the top of the spray head 782 being in communication with the inside of the feeding ring 781, a flow guide block 783 slidingly arranged in the inside of the spray head 782, a push rod 784 fixedly connected at the top of the flow guide block 783, a push plate 785 slidingly arranged in the inside cavity of the guide disc 72, and the top of the push rod 784 being fixedly connected with the bottom of the push plate 785. When the "cross" shaped push plate 785 moves upward, the circular truncated cone type flow guide block 783 in the spray head 782 moves upward through the push rod 784, so as to increase the cross-sectional area of the water outlet passage of the spray head 782.

The driving motor drives the rotating rod 81 to rotate, and the synchronous belt drives the guide rod 10 at the bottom end of the rotating rod 81 to slide along the spiral guide groove 9 on the inner wall of the moving sleeve 85, so that the rotating motion of the rotating rod 81 is converted into the upward motion of the moving sleeve 85 in the vertical direction. If the impurity concentration in the sewage is high, the stirring resistance increases, the rotating rod 81 in the cavity of the driving rod 6 can further press the annular spring 82 to slightly rotate by the extrusion plate 83, and the torque can be buffered by compressing the annular spring 82 by the extrusion plate 83, while the moving sleeve 85 can be slightly adjusted to displace upward, further optimizing the position of the flow guide block 783, and increasing the cross-sectional area of the water outlet channel of the nozzle 782.

[0022] As an embodiment of the present application, the left top of the impurity treatment shell 5 is connected with the sewage treatment tank 2, and the inside of the impurity treatment shell 5 is provided with an auger conveying rod 11 through a motor, and a sludge outlet is formed at the bottom of the end of the impurity treatment shell 5 away from the sewage treatment tank 2. Start the motor on one side of the impurity treatment shell 5 to drive the auger conveying rod 11 to rotate to generate axial thrust, continuously push the precipitated flocculation sludge along the inner wall of the shell to the end away from the sewage treatment tank 2, and finally discharge from the sludge outlet, realizing the complete separation of sludge and water body.

[0023] Working principle: when using the sewage discharge device with flocculation function for construction engineering, first, the construction engineering sewage is introduced through the water inlet 3 on the left side of the top of the sewage treatment tank 2, and the water inlet flow is controlled and the specified liquid level in the tank is controlled. Start the driving motor at the top of the sewage treatment tank 2, the driving motor drives the rotating rod 81 to rotate, the rotating rod 81 drives the extrusion plate 83 to rotate, the extrusion plate 83 drives the annular spring 82 to push the connecting plate 84 to drive the driving rod 6 to rotate, and then drives the guide disc 72 to rotate along the inner wall of the tank body, the guide disc 72 drives the sliding block at the top of the stirring rod 75 to slide along the elliptical sliding groove 76 at the bottom of the rotating disc 71, so that the two groups of stirring rods 75 are synchronously moved along the guide groove 73 radially, the rack 74 on the inner wall of the guide groove 73 is engaged with the gear 77 on the surface of the stirring rod 75 to drive the stirring rod 75 to rotate, realizing the compound motion of the two groups of stirring rods 75 rotating around the driving rod 6 and moving radially back and forth, so that the two groups of interleaved paddles move with the stirring rod 75, covering the whole area of the sewage treatment tank 2 from the center to the inner wall, breaking the sand and sludge lumps in the sewage, and forming a uniform turbulent flow field to create conditions for flocculant mixing; The driving motor drives the rotating rod 81 to rotate, and the synchronous belt drives the guide rod 10 at the bottom end of the rotating rod 81 to slide along the spiral guide groove 9 on the inner wall of the moving sleeve 85, converting the rotating motion of the rotating rod 81 into the upward motion of the moving sleeve 85 in the vertical direction. While the moving sleeve 85 moves upward, the bottom connecting rod pulls the "X" shaped push plate 785 inside the guide disc 72 upward, and the upward movement of the push plate 785 drives the circular table type flow guide block 783 inside the nozzle 782 upward through the push rod 784, increasing the cross-sectional area of the water outlet channel of the nozzle 782. At this time, the flocculating agent flows into the four groups of circumferentially distributed nozzles 782 from the feeding ring 781 and is uniformly sprayed into the sewage in the tank. If the impurity concentration in the sewage is high, the rotating rod 81 in the cavity of the driving rod 6 will further squeeze the annular spring 82 to rotate slightly, and the torque will be buffered by the annular spring 82 compressed by the squeezing plate 83, and at the same time, the moving sleeve 85 can be slightly adjusted to move upward, further optimizing the position of the flow guide block 783, increasing the cross-sectional area of the water outlet channel of the nozzle 782, and increasing the amount of flocculating agent sprayed, to ensure that the flocculation reaction is sufficient. Under the combined action of flocculating agent and sewage, suspended particles, sand and other impurities in the sewage gradually aggregate to form flocs, which are precipitated to the bottom of the sewage treatment tank 2 under the action of gravity and enter the impurity treatment shell 5 through the tank bottom opening. Start the motor on one side of the impurity treatment shell 5 to drive the auger conveying rod 11 to rotate and generate axial thrust, continuously pushing the precipitated flocculated sludge along the inner wall of the shell away from the sewage treatment tank 2 to the end, and finally discharging from the sludge outlet, realizing the complete separation of sludge and water body.
