Meanwhile, the partition plate 512 not only connects the two adjacent choked flow cylinders 51 into a whole, but also divides the sewage into thin layers by the partition plate 512, and by utilizing the laminar flow principle, when the sewage flows in the gap between the two choked flow cylinders 51, the hydraulic radius is very small, and the water flow is in a stable laminar flow state, so that the sedimentation is very favorable, the flocculation particles in the partition plate 512 are coagulated again, the further growth of the particles is promoted, and the sedimentation efficiency is improved.

Referring to fig. 2 and 4, the lower end of the rotating shaft 41 extends into the uppermost choke cylinder 51, the lower end of the rotating shaft 41 is flush with the smaller end of the uppermost choke cylinder 51, and four spoiler rings 6 are disposed on the circumferential surface of the rotating shaft 41 inside the choke cylinder 51, and the four spoiler rings 6 are gradually increased in size upward along the height direction of the rotating shaft 41, so that the spoiler rings 6 can cover the inside of the choke cylinder 51 and do not contact with the side walls of the choke cylinder 51. The axial section of the turbulent ring 6 is triangular, the inner end angle of the turbulent ring 6 points to the rotating shaft 41, the outer end angle of the turbulent ring 6 points to the flow blocking cylinder 51, the height of the outer end angle of the turbulent ring 6 is lower than that of the inner end angle, and a gap is formed between the outer end angle of the turbulent ring 6 and the side wall of the flow blocking cylinder 51; a gap is formed between the inner side of the turbulence ring 6 and the rotating shaft 41, the turbulence ring 6 is connected with the rotating shaft 41 through a plurality of rotating rods 61, the plurality of rotating rods 61 are divided into two groups according to the height of the rotating rods 61 on the rotating shaft 41, each group is provided with four rotating rods 61, and the four rotating rods 61 in the same group are arranged in central symmetry along the axis of the rotating shaft 41; the one end that is located the dwang 61 of upside and the upper end angle fixed connection of vortex ring 6, the one end that is located the dwang 61 of downside and the lower extreme angle fixed connection of vortex ring 6, and the global fixed connection of the other end of dwang 61 and axis of rotation 41, and then with the stable fixing in axis of rotation 41 of vortex ring 6, can drive vortex ring 6 through dwang 61 when axis of rotation 41 rotates simultaneously and carry out synchronous rotation. In order to enable the turbulence ring 6 to drive the sewage to be mixed with the flocculating agent, a plurality of convex strips 612 are arranged on the inner side and the outer side of the turbulence ring 6, and the convex strips 612 on the same side are arranged in parallel; when the rotating shaft 41 rotates, the turbulence rings 6 can be synchronously driven to rotate, the convex strips 612 can drive the sewage to generate centrifugal motion, so that the flow rate of the sewage is higher, and the mixed precipitation effect of the flocculating agent and the impurity particles in the sewage is improved.

For the sewage entering the flow-resisting cylinder 51, the sewage firstly contacts the inclined side wall of the flow-disturbing ring 6, so that the sewage flows upwards along the side walls of the flow-resisting cylinder 51 and the flow-disturbing ring 6, the flow speed of the sewage is accelerated when the sewage passes through the gap between the flow-resisting cylinder 51 and the flow-disturbing ring 6, and the flow speed of the sewage after passing through the gap is slowed down, so that the sewage is subjected to acceleration and deceleration, and then solid particles are flocculated and aggregated, so that the sewage can be rapidly precipitated; meanwhile, the flow path of the sewage can be further increased through the flow disturbing ring 6, and the sedimentation effect is improved.

Referring to fig. 2 and 4, the flow increasing cylinder 52 is located at the lower side of the flow blocking cylinder 51, the flow increasing cylinder 52 is in a truncated cone shape and is coaxially arranged with the settling tank 1, and the smaller end of the flow increasing cylinder 52 is arranged toward the bottom of the settling tank 1. The sidewall of the flow increasing cylinder 52 is composed of a plurality of rectifying plates 521, the lower ends of the rectifying plates 521 are connected with first connecting rings 522, the upper ends of the rectifying plates 521 are connected with second connecting rings 523, and the first connecting rings 522 and the second connecting rings 523 are arranged in parallel. The lower ends of the plurality of rectifier plates 521 are connected with each other through a first connecting ring 522 to form a smaller end of the flow increasing cylinder 52, the other ends of the rectifier plates 521 are connected with each other through a second connecting ring 523 to form a larger end of the flow increasing cylinder 52, and the outer ring side wall of the second connecting ring 523 is fixedly connected with the side wall of the settling tank 1; in the direction from the smaller end to the larger end of the flow increasing cylinder 52, a water passage 524 is formed between the adjacent rectifying plates 521, and the size of the water passage 524 is gradually increased. The overflow pipe 53 is positioned inside the flow increasing cylinder 52 and is coaxially arranged with the flow increasing cylinder 52, the diameter of the overflow pipe 53 is equal to that of the smaller end of the flow increasing cylinder 52, and two helical blades 531 with opposite rotation directions are fixedly connected in the overflow pipe 53.

When the sewage moves upwards from the bottom of the settling tank 1, part of the sewage enters the overflow pipe 53 from the smaller end of the flow increasing cylinder 52, the flowing path of the sewage can be increased through the sewage in the overflow pipe 53, and meanwhile, the sewage can be mixed under the spiral action of the two spiral blades 531 in the overflow pipe 53, so that the sewage and the flocculating agent can be mixed more uniformly, and the effect of removing impurity particles in the sewage is further improved; the remaining part of the sewage will move upwards through the outer side wall of the flow-increasing cylinder 52, and the upward path is blocked by the second connecting ring 523, so that the sewage will enter the inside of the flow-increasing cylinder 52 from the water passage 524 on the side wall of the flow-increasing cylinder 52 and mix with the sewage inside the flow-increasing cylinder 52. Because the sewage outside the flow increasing cylinder 52 enters into the flow increasing cylinder 52 from the water channel 524, the movement path of the sewage is increased, and the sewage can also move spirally, so that mixed flow in the sewage movement process is realized, at the moment, the flocculating agent is added into the sewage, and the solid impurity particles existing in the sewage collide with each other to form larger impurity particles, so that self-sedimentation of the impurity particles is realized, and the impurity particles in the sewage are reduced.
