After flocculation is completed, the first solenoid valve 14 is controlled to open. When the first piston 5 moves upward, the upper layer of clean water is first discharged through the drain pipe 12. Then the first solenoid valve 14 is controlled to close and the second solenoid valve 15 is opened to discharge the flocculent material in the lower layer through the mud discharge pipe 13.

[0020] Also includes: The fixed-point mixing mechanism includes a driven disc 3 rotatably connected to the inner wall of the top of the tank body 1, a stirring assembly installed inside the driven disc 3 and a fixed ring 4 rotatably sleeved on the outside of the driven disc 3, the fixed ring 4 is fixedly connected to the inner wall of the top of the tank body 1, and a hidden groove 16 is provided at the bottom of the driven disc 3; the stirring assembly includes a driving sleeve 17 slidably connected to the inside of the hidden groove 16, a plurality of stirring blades 18 fixedly connected to the outside of the driving sleeve 17 and a main shaft 19 fixedly connected to the inner wall of the top of the hidden groove 16, and the stirring blades 18 are adapted to the hidden groove 16; the driving sleeve 17 is slidably sleeved on the outside of the main shaft 19, and the outside of the main shaft 19 is fixedly connected with a key pin, and the driving sleeve A key slot is provided inside 17, and a key pin is slidably connected inside the key slot. The bottom end of the main shaft 19 is rotatably connected to the center of the bottom of the tank body 1. A slider 171 is fixed to the outside of the drive sleeve 17, and a slide slot 172 is provided inside the hidden groove 16. The slider 171 is slidably connected to the inside of the slide slot 172. When the slider 171 moves down to the bottom of the slide slot 172, it cannot move further downward. This position is the limit downward position of the drive sleeve 17 and the stirring blade 18. The top of the drive sleeve 17 is fixedly connected to the first spring 20. The first spring 20 is sleeved on the outside of the main shaft 19, and the top of the first spring 20 is fixed to the inner wall of the top of the hidden groove 16.

The partition 9 moves downward synchronously. After the wastewater and flocculant are injected into the tank body 1, they are located at the top of the partition 9. By driving the main shaft 19 to rotate, the drive sleeve 17 and the stirring blade 18 rotate synchronously to mix the wastewater and flocculant on the top of the partition 9.

The two drive shafts 21 are connected to each other through a transmission assembly 26, and the transmission assembly 26 includes synchronous wheels fixedly sleeved on the outside of the two drive shafts 21 and a synchronous belt connected to the outside of the two synchronous wheels; the outside of the two reciprocating screws 22 are screwed with a lifting block 27, and the top of the lifting block 27 is fixedly connected to two lifting rods 28, and the top of the lifting rod 28 is fixedly connected to the bottom of the first piston 5; By controlling the motor 23 to drive the driving gear 24 to rotate forward, the driving gear 24 is engaged with the first one-way gear 25 to drive one of the driving shafts 21 to rotate. At this time, the second one-way gear 29 also rotates synchronously, but the main shaft 19 does not rotate accordingly. When one of the driving shafts 21 rotates, the two driving shafts 21 are kept in synchronous rotation through the transmission connection of the transmission assembly 26, thereby driving the two reciprocating screws 22 to rotate synchronously, driving the lifting block 27 to move downward, and then driving the first piston 5 to move downward synchronously through the lifting rod 28. Among them, the control motor 23 drives the first piston 5 to move downward in sections, and the distance of each downward movement is the same. After the lifting block 27 moves down to the bottom end of the reciprocating screw 22, it continues to drive the reciprocating screw 22 to rotate, and can drive the lifting block 27 to move upward along the outside of the reciprocating screw 22. By driving the first piston 5 downward in sections, the wastewater can be introduced into the tank body 1 in sections, and the wastewater is subjected to section-by-section flocculation treatment, thereby improving the adequacy of the wastewater flocculation.

[0022] The main shaft 19 is sequentially arranged to pass through the first piston 5, the partition plate 9 and the lifting block 27; a second one-way gear 29 is installed on the outside of the main shaft 19, and the second one-way gear 29 is meshed with the driving gear 24; By controlling the motor 23 to drive the driving gear 24 to reverse, the main shaft 19 is driven to rotate through the meshing effect between the driving gear 24 and the second one-way gear 29. At this time, the first one-way gear 25 also rotates, but the driving shaft 21 does not rotate. When the main shaft 19 rotates, the driven disc 3, the driving sleeve 17 and the stirring blade 18 are driven to rotate synchronously.

[0023] The linkage dosing mechanism includes a metering cylinder 6 mounted on the outer wall of one side of the tank body 1, a second piston 7 mounted inside the metering cylinder 6, and a drug guide hose 8 mounted on the bottom of one side of the metering cylinder 6. The top of the drug guide hose 8 is connected to the wastewater pipe 2. A drug feed pipe 30 is mounted on the top of the metering cylinder 6. A third one-way valve 43 is mounted on the drug feed pipe 30. The setting of the third one-way valve 43 allows the flocculant to enter the inside of the metering cylinder 6 through the drug feed pipe 30, and the flocculant inside the metering cylinder 6 cannot be discharged through the drug feed pipe 30. The bottom of the second piston 7 is fixed with a linkage rod 3 1, the bottom end of the linkage rod 31 extends to the outside of the metering cylinder 6 and is fixedly connected to one end of the lifting block 27; a through groove 32 is formed on the outer wall of one side of the tank body 1, and the lifting block 27 is slidably connected to the inside of the through groove 32; a plurality of second conduits 33 are installed inside the second piston 7, and a second one-way valve 34 is installed on the second conduit 33. The configuration of the second one-way valve 34 allows flocculant at the top of the second piston 7 to reach the bottom of the second piston 7 through the second conduit 33, while preventing flocculant at the bottom of the second piston 7 from reaching the top of the second piston 7 through the second conduit 33; When the lifting block 27 moves downward, the second piston 7 is driven to move downward along the inner wall of the metering cylinder 6 through the linkage rod 31. During this process, the flocculant is introduced into the interior of the metering cylinder 6 through the drug inlet pipe 30, and at the same time, the flocculant at the bottom of the second piston 7 is introduced into the interior of the wastewater pipe 2 through the drug guide hose 8. Moreover, since the lifting block 27 moves in sections, the flocculant inside the metering cylinder 6 is synchronously driven to be introduced into the interior of the wastewater pipe 2 in sections, thereby achieving a segmented quantitative mixing effect with the wastewater. When the lifting block 27 moves upward, the second piston 7 is driven to move upward along the inner wall of the metering cylinder 6 through the linkage rod 31 , and the flocculant on the top of the second piston 7 reaches the bottom of the second piston 7 through the second conduit 33 .

[0024] The mud-water separation mechanism includes a partition 9 installed at the bottom of the stirring assembly, a plurality of first conduits 10 installed inside the partition 9, and two filter assemblies installed inside the partition 9. The partition 9 is arranged between the driven disc 3 and the first piston 5. The partition 9 is fixedly connected to the bottom of the drive sleeve 17. A third solenoid valve 35 is installed on the first conduit 10. When the first piston 5 moves downward, the third solenoid valve 35 is controlled to open. When the first piston 5 stops moving, the third solenoid valve 35 is controlled to close. The filter assembly includes a through groove 36 provided inside the partition 9, a filter screen 37 provided inside the through groove 36, and a plurality of movable grooves 38 provided inside the partition 9. The filter screen 37 is initially located at the bottom of the mud discharge pipe 13. When the partition 9 follows the rotation of the drive sleeve 17, the filter screen 37 is opened. After a certain number of flocculation turns are completed, the filter screen 37 is located directly below the mud discharge pipe 13; a movable block 39 is installed inside the movable groove 38, and a slide rod 40 is fixed to the top of the movable block 39. The top of the slide rod 40 extends to the inside of the through groove 36 and is fixed to the bottom of the filter screen 37; a second spring 41 is fixed to the bottom of the movable block 39, and the bottom end of the second spring 41 is fixed to the inner wall of the bottom of the movable groove 38. The sum of the elastic forces of the second spring 41 is greater than the elastic force of the first spring 20; a pressure sensor 42 is also installed on the inner wall of one side of the movable groove 38, and the pressure sensor 42 is located above the movable block 39; the filter screens 37 in the two filter assemblies correspond to the two mud discharge pipes 13 respectively, and the outer diameter of the filter screen 37 is smaller than the inner diameter of the mud discharge pipe 13; After the wastewater flocculation is completed, the first piston 5 is driven to move upward. At this time, the first solenoid valve 14 is opened, and the clean water on the upper layer after flocculation can pass through the filter screen 37, and the clean water is discharged through the drain pipe 12. When the clean water is discharged, the flocculent material reaches the bottom of the partition 9. As the first piston 5 continues to move upward, the partition 9 is driven to move upward, and the driving sleeve 17 and the stirring blade 18 enter the interior of the hidden groove 16. The two filter screens 37 are respectively moved up to the bottom of the two mud discharge pipes 13. As the first piston 5 continues to move upward, the flocculent material is pushed through the filter screen 37. The filter screen 37 moves upward into the mud discharge pipe 13, and the slide rod 40 and the movable block 39 move upward synchronously therewith. When the movable block 39 abuts against the pressure sensor 42, the pressure sensor 42 is subjected to pressure and transmits a signal to the controller. The controller controls the first solenoid valve 14 to close and the second solenoid valve 15 to open, so that the flocculants on the top of the first piston 5 enter the mud discharge pipe 13 through the through groove 36 and are discharged. By separating and discharging clean water and flocculants, the moisture in the flocculant sediment is reduced, and the convenience of subsequent flocculant sediment treatment is improved.

[0025] Working principle: while introducing wastewater and flocculant into the tank body 1 through the wastewater pipe 2, the two reciprocating screws 22 are driven to rotate synchronously by the control motor 23, driving the lifting block 27 to move downward, and then driving the first piston 5 to move downward synchronously through the lifting rod 28. The rebound force of the first spring 20 drives the driving sleeve 17 to slide downward, and each stirring blade 18 is moved out of the hidden groove 16, and the partition 9 moves downward synchronously. After the wastewater and flocculant are injected into the tank body 1, they are located on the top of the partition 9. By driving the main shaft 19 to rotate, the driving sleeve 17 and the stirring blade 18 rotate synchronously, mixing the wastewater and flocculant on the top of the partition 9. After the mixing is completed, the first piston 5 is continued to be driven. The stirring blade 18 moves downward, but at this time the stirring blade 18 and the partition 9 move to the maximum limit and do not move downward. When the first piston 5 moves downward, the wastewater mixed on the top of the partition 9 reaches the top of the first piston 5 through the first conduit 10, and the wastewater in the wastewater pipe 2 continues to reach the top of the partition 9, and continues to drive the stirring blade 18 to mix the wastewater on the top of the partition 9. By driving the stirring blade 18 to mix the wastewater at the set height, the problem of the stirring blade 18 re-dispersing the flocculated precipitates that have been flocculated is avoided, thereby improving the flocculation effect of the wastewater. When the lifting block 27 moves downward, the linkage rod 31 drives the second piston 7 to move downward along the inner wall of the metering cylinder 6. In this process, by feeding the medicine The tube 30 introduces the flocculant into the interior of the metering cylinder 6, and at the same time, the flocculant at the bottom of the second piston 7 is introduced into the interior of the wastewater pipe 2 through the drug guide hose 8. Since the lifting block 27 moves in sections, the flocculant inside the metering cylinder 6 is synchronously driven to be introduced into the interior of the wastewater pipe 2 in sections, thereby achieving a segmented quantitative mixing effect with the wastewater. After the wastewater flocculation is completed, the first piston 5 is driven to move upward. At this time, the first solenoid valve 14 is opened, and the clean water on the upper layer after flocculation can pass through the filter screen 37, and the clean water is discharged through the drain pipe 12. When the clean water is discharged, the flocculant part reaches the bottom of the partition 9. As the first piston 5 continues to move upward, the partition 9 is driven to move upward, and the drive sleeve 17 and the stirring blade 18 are driven in. The filter screens 37 are moved up to the bottom of the two mud discharge pipes 13 respectively as the first piston 5 continues to move upward, and the flocculants push the filter screens 37 to move upward into the mud discharge pipe 13, and the slide rod 40 and the movable block 39 move upward synchronously therewith. When the movable block 39 abuts against the pressure sensor 42, the pressure sensor 42 is subjected to pressure and transmits a signal to the controller. The controller controls the first solenoid valve 14 to close and the second solenoid valve 15 to open, so that the flocculants on the top of the first piston 5 enter the mud discharge pipe 13 through the through groove 36 and are discharged. By separating and discharging clean water and flocculants, the moisture in the flocculant sediment is reduced, and the convenience of subsequent flocculant sediment treatment is improved.
