When the flocculate is required to be cleaned, the second shrinkage part 7b of the opening and closing air bag 7 is controlled to expand towards the inner barrel 2, so that the second shrinkage part 7b is tightly attached to the outer wall of the inner barrel 2, a fourth cavity 400 is formed between the circular ring 6 and the opening and closing air bag 7, dirt flowing down from the upper part is intercepted and collected through the fourth cavity 400, the dirt is prevented from flowing into the second cavity 200, the cleanliness of the second cavity 200 is influenced, and therefore, when the fourth cavity 400 is used for discharging, the water flow in the process of outputting from the second cavity 200 to the third cavity 300 is not influenced, and thus, the discharging work, the reaction and the precipitation work are synchronously carried out, and the problem that in the prior art, when the inside of the precipitator is discharged, the reaction and the precipitation work cannot be synchronously carried out is solved.
Then, the telescopic part of the electric push rod 101 is controlled to drive the connecting ring 102 to move downwards, so that the connecting ring 102 drives the interception ring 5 to move downwards, and the interception ring 5 drives the inner ring part of the circular ring 6 to move downwards, so that the circular ring 6 is converted into a conical shape with a large top and a small bottom from the circular shape shown in fig. 4; when reaching the maximum stretching value of the ring 6, the interception ring 5 still moves downwards, and as the interception ring 5 and the ring 6 are connected in a clamping manner, the interception ring 5 and the ring 6 are separated along with the continuous downward movement of the interception ring 5, at this time, the position states of the interception ring 5 and the ring 6 are as shown in fig. 7, a gap is formed between the interception ring 5 and the ring 6, and the first cavity 100 is communicated with the fourth cavity 400, so that water flow and flocculate can quickly enter the fourth cavity 400 through the gap.
Meanwhile, due to the separation of the interception ring 5 and the circular ring 6, the air inlet hole 5a and the air outlet hole 6b are not communicated any more, and at the moment, the air inlet hole 5a is exposed, so that the air in the interception ring 5 is discharged from the air inlet hole 5a, the first contraction part 5b is quickly contracted, and a gap 5c between the first contraction part 5b and the outer wall of the inner cylinder 2 is larger; so that the flocs caught between the first constriction 5b and the outer wall of the inner tube 2 can smoothly drop down into the fourth cavity 400.
Because the flocculate has certain adhesiveness, part of the flocculate blocked in the gap 5c can adhere to the outer wall of the inner cylinder 2, if the flocculate is not cleaned, more and more flocculate on the outer wall of the inner cylinder 2 can be caused to adhere, and even if the interception ring 5 and the circular ring 6 are separated and then restored, the blocking phenomenon can be caused rapidly; at this time, due to the exposure of the air outlet 6b, the air outlet 6b is inclined towards the outer wall of the inner cylinder 2, and the air flow is blown out to the outer wall of the inner cylinder 2 through the air outlet 6b, and the flocculate adhered to the outer wall of the inner cylinder 2 is impacted by the air flow, so that the flocculate can smoothly drop down into the fourth cavity 400, and the cleaning effect of the flocculate adhered to the outer wall of the inner cylinder 2 is realized.
Meanwhile, the circular ring 6 is in a conical shape with a large upper part and a small lower part as shown in fig. 7, so that water flow passing through the circular ring 6 is more turbulent and has larger impact force, namely, the interception ring 5, the circular ring 6 and connecting parts thereof can be washed by the water flow at the part, and flocculates adhered to the outer wall of the inner cylinder 2 can be washed, so that the flocculates adhered to the outer wall of the inner cylinder 2 can be better removed by multiple impact of air flow and water flow;
after the outer wall of the inner cylinder 2, the interception ring 5, the circular ring 6 and flocculates of connecting components thereof enter the fourth cavity 400, the telescopic part of the electric push rod 101 is controlled to drive the connection ring 102 and the interception ring 5 to move upwards, so that the electric push rod can be clamped between the circular rings 6 again, the air inlet holes 5a and the air outlet holes 6b are restored to a communication state, and then air is continuously injected into the interception ring 5 through the air outlet holes 6b and the air inlet holes 5a, so that the first telescopic part 5b can expand towards the outer wall of the inner cylinder 2, and the state shown in fig. 6 is restored; along with the continuous upward movement of the interception ring 5, the circular ring 6 is driven to move upward, so that the interception ring 5 and the circular ring 6 are restored to the state shown in fig. 4 from the state shown in fig. 7, and the interception work is continued;
then, the sewage suction pipe 8 is controlled to suck out the water flow and the flocculate in the fourth cavity 400, so that the flocculate is removed, the flocculate content in the third cavity 300 is reduced, and the water purifying effect is improved.

The inner cylinder 2 is rotationally connected with the conical guide ring 4, and the conical guide ring 4 is provided with a driving motor; the conical guide ring 4 is driven by the driving motor to rotate clockwise from the top down view angle, so that water overflowed from the inner cylinder 2 can be evenly thrown away along the outer surface of the conical guide ring 4, and the water is prevented from flowing down in a stranding manner.
The dirt removal work of the cone-shaped guide ring 4 is as follows:
after the conical guide ring 4 performs guide work for a long time, a large amount of flocculate is adhered to the outer surface of the conical guide ring 4, so that more flocculate appears in a part of the upper surface area of the conical guide ring 4, water cannot smoothly flow through the conical guide ring, and only flows along other areas, so that the water cannot be dispersed, but a strand-shaped water flow is formed, the impact force of the water flow is increased, the lower flocculate is impacted, and the water purifying effect is influenced, so that the flocculate adhered to the outer surface of the conical guide ring 4 is required to be removed;
firstly, the connecting rod 303 and the connecting component thereof are driven by the moving block 302 to move anticlockwise and circularly on the annular guide rail 301 from top to bottom, and flocs adhered to the outer wall of the conical guide ring 4 and the inner wall of the middle cylinder 3 are scraped by the scraping plate 305 and the scraping block 306, accumulated on the bearing strip 307 and discharged by external dirt cleaning equipment;
meanwhile, the blocking strip 304 is used for blocking water overflowed from the inner cylinder 2, so that the water is prevented from impacting flocculates accumulated on the receiving strip 307, the flocculates flow downwards, the flocculate content in the first cavity 100 and the second cavity 200 is increased, and the water purifying effect is influenced;
