[0048] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0049] Example: Please refer to Figure 1 - Figure 11 A wastewater treatment device based on chemical raw material production includes a tank 1 and a wastewater pipe 2. A first check valve 11 is installed on the wastewater pipe 2. The first check valve 11 allows wastewater to enter the tank 1 through the wastewater pipe 2, but the wastewater inside the tank 1 cannot be discharged through the wastewater pipe 2. The wastewater pipe 2 is connected through a fixing ring 4. The bottom end of the wastewater pipe 2 has a funnel-shaped structure. When the liquid flocculant and wastewater are mixed in the wastewater pipe 2, the flocculant and wastewater are premixed inside the wastewater pipe 2 because the bottom opening of the wastewater pipe 2 is small. A drain pipe 12 and two sludge discharge pipes 13 are also installed on the top of the tank 1. A first solenoid valve 14 is installed on the drain pipe 12, and a second solenoid valve 15 is installed on the sludge discharge pipes 13. Both the drain pipe 12 and the sludge discharge pipes 13 are connected through the fixing ring 4.

[0050] Chemical wastewater is introduced into the tank 1 through wastewater pipe 2. After flocculation, the first solenoid valve 14 is opened first. When the first piston 5 moves upward, the upper layer of clean water is discharged through the drain pipe 12. Then the first solenoid valve 14 is closed and the second solenoid valve 15 is opened to discharge the lower layer of flocs through the sludge discharge pipe 13.

[0051] Also includes:

[0052] A fixed-point mixing mechanism includes a driven disc 3 rotatably connected to the inner wall of the top of a tank 1, a stirring assembly installed inside the driven disc 3, and a fixing ring 4 rotatably sleeved on the outside of the driven disc 3. The fixing ring 4 is fixed to the inner wall of the top of the tank 1. A hidden groove 16 is provided at the bottom of the driven disc 3. The stirring assembly includes a drive sleeve 17 slidably connected inside the hidden groove 16, multiple stirring blades 18 fixed to the outside of the drive sleeve 17, and a main shaft 19 fixed to the inner wall of the top of the hidden groove 16. The stirring blades 18 are adapted to the hidden groove 16. The drive sleeve 17 is slidably sleeved on the outside of the main shaft 19. A key pin is fixed to the outside of the main shaft 19. The drive sleeve 17 has a keyway inside, and a key pin is slidably connected inside the keyway. The bottom end of the main shaft 19 is rotatably connected to the center of the bottom of the tank 1. A slider 171 is fixedly connected to the outside of the drive sleeve 17. A slide groove 172 is opened inside the hidden groove 16. The slider 171 is slidably connected inside the slide groove 172. When the slider 171 moves down to the bottom of the slide groove 172, it cannot move further down. This position is the limit of the downward movement of the drive sleeve 17 and the stirring blade 18. A first spring 20 is fixedly connected to the top of the drive sleeve 17. The first spring 20 is sleeved on the outside of the main shaft 19. The top of the first spring 20 is fixedly connected to the inner wall of the top of the hidden groove 16.

[0053] When the first piston 5 moves downward, the rebound force of the first spring 20 causes the drive sleeve 17 to slide downward, and each stirring blade 18 moves out of the hidden groove 16. The baffle 9 moves downward synchronously. After the wastewater and flocculant are injected into the tank 1, they are located at the top of the baffle 9. By driving the main shaft 19 to rotate, the drive sleeve 17 and stirring blade 18 rotate synchronously to mix the wastewater and flocculant at the top of the baffle 9. After mixing, the first piston 5 continues to move downward, but at this time the stirring blade 18 and the baffle 9 move to the maximum extent and do not move downward. When the first piston 5 moves downward, the wastewater that has been mixed at the top of the baffle 9 reaches the top of the first piston 5 through the first conduit 10. The wastewater in the wastewater pipe 2 then continues to reach the top of the baffle 9, and the stirring blade 18 continues to mix the wastewater at the top of the baffle 9. By driving the stirring blade 18 to mix the wastewater at a set height, the problem of the stirring blade 18 re-dispersing the already flocculated precipitate is avoided, thus improving the flocculation effect of the wastewater.

[0054] The segmented flocculation mechanism includes a first piston 5 disposed inside a tank 1 and a lifting assembly for driving the first piston 5 to move in segments. The lifting assembly includes two drive shafts 21 rotatably connected to the inner wall of the bottom of the tank 1, reciprocating screws 22 fixedly sleeved on the outside of the drive shafts 21, and a motor 23 mounted on the inner wall of the bottom of the tank 1. A drive gear 24 is fixedly connected to the output end of the motor 23. A first one-way gear 25 is mounted on the outside of one of the drive shafts 21, and the drive gear 24 meshes with the first one-way gear 25. The two drive shafts 21 are connected by a transmission assembly 26. The transmission assembly 26 includes synchronous pulleys fixedly sleeved on the outside of the two drive shafts 21 and a synchronous belt connected to the outside of the two synchronous pulleys. Lifting blocks 27 are screwed to the outside of the two reciprocating screws 22. Two lifting rods 28 are fixedly connected to the top of the lifting blocks 27, and the top of the lifting rods 28 are fixedly connected to the bottom of the first piston 5.

[0055] By controlling the motor 23 to drive the drive gear 24 to rotate forward, and through the meshing action between the drive gear 24 and the first one-way gear 25, one of the drive shafts 21 is driven to rotate. At this time, the second one-way gear 29 also rotates synchronously, but the main shaft 19 does not rotate. When one of the drive shafts 21 rotates, through the transmission component 26, the two drive shafts 21 are connected to maintain synchronous rotation, 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. The control motor 23 drives the first piston 5 to move downward in segments, and the distance of each downward movement is the same. After the lifting block 27 moves down to the bottom of the reciprocating screw 22, when the reciprocating screw 22 is continued to rotate, the lifting block 27 can be driven to move upward along the outside of the reciprocating screw 22. By driving the first piston 5 to move downward in segments, the wastewater can be introduced into the tank 1 in segments for segmented flocculation treatment, which improves the sufficiency of wastewater flocculation.

[0056] The main shaft 19 is arranged to pass through the first piston 5, the partition plate 9 and the lifting block 27 in sequence; a second one-way gear 29 is installed on the outside of the main shaft 19, and the second one-way gear 29 meshes with the driving gear 24;

[0057] By controlling the motor 23 to drive the drive gear 24 to reverse, the drive gear 24 and the second one-way gear 29 mesh together, driving the main shaft 19 to rotate. At this time, the first one-way gear 25 also rotates, but the drive shaft 21 does not rotate. When the main shaft 19 rotates, it drives the driven disk 3, the drive sleeve 17 and the stirring blade 18 to rotate synchronously.

[0058] The linkage dosing mechanism includes a metering cylinder 6 installed on the outer wall of one side of the tank 1, a second piston 7 installed inside the metering cylinder 6, and a dosing hose 8 installed at the bottom of one side of the metering cylinder 6. The top end of the dosing hose 8 is connected to the wastewater pipe 2. A dosing inlet pipe 30 is installed at the top end of the metering cylinder 6, and a third check valve 43 is installed on the dosing inlet pipe 30. The third check valve 43 allows flocculant to enter the metering cylinder 6 through the dosing inlet pipe 30, but prevents the flocculant inside the metering cylinder 6 from being discharged through the dosing inlet pipe 30. A linkage rod 3 is fixedly connected to the bottom of the second piston 7. 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 provided on the outer wall of one side of the tank body 1, and the lifting block 27 is slidably connected inside the through groove 32; multiple 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 setting of the second one-way valve 34 allows the flocculant at the top of the second piston 7 to reach the bottom of the second piston 7 through the second conduit 33, while the flocculant at the bottom of the second piston 7 cannot reach the top of the second piston 7 through the second conduit 33.

[0059] When the lifting block 27 moves downward, it drives the second piston 7 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 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 wastewater pipe 2 through the drug delivery hose 8. Since the lifting block 27 moves in segments, the flocculant inside the metering cylinder 6 is synchronously driven to be introduced into the wastewater pipe 2 in segments, so as to achieve the segmented metered mixing effect with the wastewater.

[0060] When the lifting block 27 moves upward, it drives the second piston 7 to move upward along the inner wall of the metering cylinder 6 via the linkage rod 31. The flocculant at the top of the second piston 7 reaches the bottom of the second piston 7 through the second conduit 33.

[0061] The mud-water separation mechanism includes a baffle 9 installed at the bottom of the mixing assembly, multiple first conduits 10 installed inside the baffle 9, and two filter assemblies installed inside the baffle 9. The baffle 9 is positioned between the driven disc 3 and the first piston 5, and is fixed 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 opened; when the first piston 5 stops moving, the third solenoid valve 35 is closed. The filter assemblies include a through groove 36 opened inside the baffle 9, a filter screen 37 installed inside the through groove 36, and multiple movable slots 38 opened inside the baffle 9. The filter screen 37 is initially located at the bottom of the mud discharge pipe 13. When the baffle 9 rotates with the drive sleeve 17, the filter screen 37 is positioned at the bottom of the mud discharge pipe 13. After the flocculation is completed with a certain number of cycles, the filter screen 37 is located directly below the sludge discharge pipe 13; a movable block 39 is installed inside the movable trough 38, and a sliding rod 40 is fixedly connected to the top of the movable block 39. The top of the sliding rod 40 extends into the interior of the through trough 36 and is fixedly connected to the bottom of the filter screen 37; a second spring 41 is fixedly connected to the bottom of the movable block 39, and the bottom end of the second spring 41 is fixedly connected to the inner wall of the bottom of the movable trough 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 trough 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 sludge discharge pipes 13 respectively, and the outer diameter of the filter screen 37 is smaller than the inner diameter of the sludge discharge pipe 13;

[0062] After the wastewater flocculation is completed, the first piston 5 is driven to move upward. At this time, the first solenoid valve 14 opens, and the clear water in the upper layer after flocculation can pass through the filter screen 37. The clear water is discharged through the drain pipe 12. When the clear water is discharged, the flocculated material reaches the bottom of the baffle 9. As the first piston 5 continues to move upward, the baffle 9 is driven to move upward. The drive sleeve 17 and the stirring blade 18 then enter the interior of the hidden tank 16. The two filter screens 37 move upward to the bottom of the two sludge discharge pipes 13 respectively. As the first piston 5 continues to move upward, the flocculated material is pushed through... The filter screen 37 moves upward and enters the sludge discharge pipe 13, and the slide rod 40 and the movable block 39 move upward synchronously. When the movable block 39 comes into contact with 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 flocculent material at the top of the first piston 5 enters the sludge discharge pipe 13 through the through groove 36 and is discharged. By separating and discharging the clean water and flocculent material, the water content in the flocculent sediment is reduced, and the convenience of subsequent flocculent sediment treatment is improved.

[0063] Working principle: Wastewater and flocculant are introduced into tank 1 through wastewater pipe 2. Simultaneously, motor 23 drives two reciprocating screws 22 to rotate synchronously, causing lifting block 27 to move downwards. This, in turn, causes lifting rod 28 to drive first piston 5 to move downwards synchronously. The rebound force of first spring 20 causes drive sleeve 17 to slide downwards, and each stirring blade 18 moves out of the hidden groove 16. Baffle 9 moves downwards synchronously as well. After the wastewater and flocculant are injected into tank 1, they are located at the top of baffle 9. Driven by the rotation of main shaft 19, drive sleeve 17 and stirring blades 18 rotate synchronously, mixing the wastewater and flocculant at the top of baffle 9. After mixing, the first piston 5 continues to be driven... The piston moves downwards, but at this time, the stirring blade 18 and the baffle 9 move to their maximum extent and do not move downwards accordingly. When the first piston 5 moves downwards, the wastewater that has been mixed at the top of the baffle 9 reaches the top of the first piston 5 through the first conduit 10. The wastewater in the wastewater pipe 2 then continues to reach the top of the baffle 9, continuing to drive the stirring blade 18 to mix the wastewater at the top of the baffle 9. By driving the stirring blade 18 to mix the wastewater at a set height, the problem of the stirring blade 18 re-dispersing the already flocculated precipitate is avoided, thus improving the flocculation effect of the wastewater. When the lifting block 27 moves downwards, it drives the second piston 7 to move downwards along the inner wall of the metering cylinder 6 through the linkage rod 31. During this process, the drug is fed... Pipe 30 introduces flocculant into the metering cylinder 6, while simultaneously introducing flocculant from the bottom of the second piston 7 into the wastewater pipe 2 via the dosing hose 8. Since the lifting block 27 moves in segments, the flocculant inside the metering cylinder 6 is synchronously driven to be introduced into the wastewater pipe 2 in segments, achieving a segmented, metered mixing effect with the wastewater. After the wastewater flocculation is complete, the first piston 5 is driven to move upwards. At this time, the first solenoid valve 14 opens, and the upper layer of clear water after flocculation can pass through the filter screen 37 and be discharged through the drain pipe 12. When the clear water is discharged, the flocculent reaches the bottom of the baffle 9. As the first piston 5 continues to move upwards, the baffle 9 is driven to move upwards, and the drive sleeve 17 and the stirring blade 18 move accordingly. Inside the hidden trough 16, the two filter screens 37 move upwards to the bottom of the two sludge discharge pipes 13. As the first piston 5 continues to move upwards, the flocculent pushes the filter screens 37 upwards into the sludge discharge pipes 13. The slide bar 40 and the movable block 39 move upwards synchronously. When the movable block 39 comes into contact with 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 flocculent at the top of the first piston 5 enters the sludge discharge pipe 13 through the through groove 36 and is discharged. By separating and discharging the clean water and flocculent, the water content in the flocculent sediment is reduced, and the convenience of subsequent flocculent sediment treatment is improved.
