The guide drive component is used to drive the auxiliary processing component to move. When the auxiliary processing component is located inside the dosing chamber 3, it is used to stir the sewage and sedimentation agent inside the dosing chamber 3. The auxiliary processing component can be cleaned when passing through the multi-functional roller group 2. The auxiliary processing component is inside the sedimentation chamber 4 for accelerating the sedimentation of industrial wastewater.

[0049] When the circumferential surfaces of adjacent multifunctional roller bodies 5 are in contact, the dosing chamber 3 and the precipitation chamber 4 can be divided. However, since the multifunctional roller body 5 has a certain elasticity, a thinner plate can pass between two adjacent multifunctional roller bodies 5 .

The two auxiliary processing plates 12 can be transformed from the first position state to the second position state, such as Fig.13 As shown, the final result is Fig.14 The third position state is shown, and can be switched between the first position state, the second position state and the third position state.

[0052] like Figure 1 , Fig.10 and Fig.11 As shown, the drive ring group includes an outer drive ring 14 and an inner drive ring 15 which are coaxially arranged, and the inner drive ring 15 and the outer drive ring 14 are both provided with connecting gear rings in the circumferential direction, and the housing 1 is fixed with a first auxiliary motor 16 and a second auxiliary motor 17, and the output shaft of the first auxiliary motor 16 and the output shaft of the second auxiliary motor 17 are respectively connected with a first driving gear and a second driving gear, and the first driving gear is meshed with the connecting gear ring of the outer drive ring 14, and the second driving gear is meshed with the connecting gear ring of the inner drive ring 15.

[0053] The first auxiliary motor 16 and the second auxiliary motor 17 are both arranged inside the connecting seat 13 , and the side of the connecting seat 13 away from the auxiliary processing board 12 is in close contact and sealed with the inner wall of the box body 1 .

The magnetic force of the limit electromagnet 20 is greater than the magnetic force of the magnetic block 21. When the limit electromagnet 20 is connected to the connecting seat 13, the first sealing plate 10 or the second sealing plate 11 can no longer move with the connecting seat 13.

[0058] The first sealing plate 10 , the second sealing plate 11 and the guide screw 8 are all in sliding connection.

[0059] When the two auxiliary processing plates 12 connected to the same driving ring group are in a closed position relationship, they can pass through two adjacently arranged multifunctional roller bodies 5 and move between the dosing chamber 3 and the precipitation chamber 4.

At the same time, the connecting seat 13 is connected to the second sealing plate 11 through the magnetic suction block 21. As the connecting seat 13 moves downward, the auxiliary processing plate 12 passes vertically between the two multifunctional roller bodies 5 to wipe and clean the outside of the auxiliary processing plate 12.

[0071] When the connecting seat 13 reaches the lower side of the multifunctional roller group 2, the first sealing plate 10 reaches the gap between the multifunctional roller group 2 and the inner wall of the box body 1. At this time, the limiting magnet is energized to magnetically attract the first sealing plate 10 through the limiting magnet;

[0072] The first auxiliary motor 16 and the second auxiliary motor 17 are operated to make the two auxiliary processing plates 12 of the same driving ring group move as shown in FIG. Fig.12 In the flattened state shown, a plurality of auxiliary processing plates 12 are evenly distributed inside the sedimentation chamber 4;

[0073] At this time, the auxiliary treatment assembly is driven downward by the guide motor 9, and the flocculants in the industrial wastewater are pressed downward by the auxiliary treatment plate 12 to achieve rapid sedimentation of the flocculants;

[0074] After the processing is completed, the auxiliary processing components are restored to the Fig.12 In the state shown, the auxiliary processing assembly is then raised to the inside of the dosing chamber 3, and at the same time, the second sealing plate 11 is restored to the gap between the multifunctional roller group 2 and the inner wall of the box body 1, so that the dosing chamber 3 and the precipitation chamber 4 are always well separated.
