Description

Technical Field

[0001] This invention relates to the field of manufactured sand wastewater treatment technology, and more specifically, to an intelligent flocculant addition control device for manufactured sand wastewater treatment. Background Technology

[0002] Currently, manufactured sand processing systems mainly employ semi-dry and wet production processes. Both processes utilize large amounts of rinsing and dust suppression water during production. Apart from a small amount consumed in the production process, most of the water mixes with fine particles in the material, forming production wastewater. If this wastewater is discharged directly into rivers without treatment, it will pollute the waterways, affecting water quality and the landscape. In terms of manufactured sand wastewater treatment, flocculation and sedimentation can not only improve the efficiency and quality of wastewater treatment but also reduce the amount of flocculant material adhering to the manufactured sand, thereby reducing the adverse effects on the subsequent use of the manufactured sand.

[0003] The existing treatment of manufactured sand wastewater mainly relies on the manual addition of flocculants. However, when adding flocculants manually, it is impossible to adjust the dosage in a timely manner according to the real-time changes in the influent water quality (such as pH fluctuations and SS concentration changes), resulting in unstable treatment effects. It is also impossible to scientifically select the strategy of adding flocculants alone or in combination, which can easily lead to waste of reagents or excessive residues. At the same time, after manual addition, it is not possible to quickly mix the flocculant with the wastewater, which affects its sedimentation efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] To address the problems in related technologies, this invention proposes an intelligent flocculant addition control device for manufactured sand wastewater treatment, in order to overcome the aforementioned technical problems existing in the prior art.

[0027] According to an embodiment of the present invention, an intelligent flocculant addition control device for treating manufactured sand wastewater is provided.

[0028] Example 1

[0029] like Figure 1-6As shown, the intelligent flocculant addition control device for treating manufactured sand wastewater according to an embodiment of the present invention includes a flocculation reaction tank 1. The top of the flocculation reaction tank 1 is provided with two symmetrically arranged flocculant storage tanks, a first flocculant storage tank 2 and a second flocculant storage tank 3. Both the first flocculant storage tank 2 and the second flocculant storage tank 3 are connected to the flocculation reaction tank 1 via a height adjustment component. The bottom of both the first flocculant storage tank 2 and the second flocculant storage tank 3 is provided with a dispensing pipe 4, on which an intelligent delivery pump 28 is installed. An inlet pipe 5 is provided on one side of the flocculation reaction tank 1, and an inlet water quality sensor group is installed on the inlet pipe 5. 6. A drain pipe 7 is provided on the side of the flocculation reaction tank 1 away from the inlet water quality sensor group 6. A drainage water quality sensor group 8 is provided on the drain pipe 7. A valve is provided on the drain pipe 7 and on the side of the drainage water quality sensor group 8. An intelligent controller 9 is provided on the side of the flocculation reaction tank 1 adjacent to the inlet pipe 5. Several evenly distributed support columns 10 are provided at the bottom of the flocculation reaction tank 1. A sewage pipe 11 is provided at the bottom of the flocculation reaction tank 1 and between the several evenly distributed support columns 10. A valve is provided on the sewage pipe 11. A stirring mechanism is provided in the flocculation reaction tank 1. The flocculant storage tank 1 2 is filled with polyferric sulfate flocculant with a concentration of 10%-15%. The flocculant storage tank 2 3 is filled with polyacrylamide flocculant with a concentration of 0.1%-0.2%. The inlet water quality sensor group 6 includes a pH sensor and a turbidity sensor. The drainage water quality sensor group 8 includes a pH sensor and a turbidity sensor. The intelligent controller 9 is one of a PLC controller and an industrial control computer, and includes a flocculant dosing optimization module. The height adjustment assembly includes symmetrically arranged L-shaped mounting brackets 12 on one side of the flocculation reaction tank 1. Both sets of L-shaped mounting brackets 12 have stroke grooves 13 on the same side. A lead screw 14 is installed in the stroke groove 13, and a fixing block 15 is fitted onto the outer wall of the lead screw 14. One side of each of the two sets of fixing blocks 15 extends outside the stroke groove 13 and is connected to the first flocculant storage tank 2 and the second flocculant storage tank 3, respectively. The lead screw 14 is connected to the L-shaped mounting bracket 12 via a bearing 16. The top end of the lead screw 14 extends outside the L-shaped mounting bracket 12 and is connected to the drive end of a servo motor 17. A threaded hole matching the lead screw 14 is provided on the fixing block 15. Symmetrically arranged guide rods 18 that penetrate the fixing block 15 are provided in the stroke groove 13.

[0030] During treatment, the wastewater from manufactured sand is fed into the flocculation reaction tank 1 through the inlet pipe 5. At this time, the pH sensor 1 and turbidity sensor 1 in the inlet water quality sensor group 6 will detect the wastewater. Subsequently, the intelligent controller 9 selects to add either polyferric sulfate flocculant from flocculant storage tank 1 2 or polyacrylamide flocculant from flocculant storage tank 2 3 based on the detection results. During addition, the intelligent delivery pump 28 is started to add the flocculant into the flocculation reaction tank 1 through the addition pipe 4. After sedimentation is completed, the purified water is discharged through the drainage water quality sensor group 8. During this process, the pH sensor 2 and turbidity sensor 2 in the drainage water quality sensor group 8 will detect the discharge water. The system performs testing to determine if the standards are met. When flocculant needs to be added to flocculant storage tank 1 (2) or flocculant storage tank 2 (3), the corresponding servo motor 17 is activated to drive the lead screw 14 to rotate. The lead screw 14 drives the fixed block 15 to move downwards, and the fixed block 15 drives the corresponding flocculant storage tank 1 (2) or flocculant storage tank 2 (3) to move downwards, making it convenient for personnel to add flocculant. By setting up flocculant storage tank 1, flocculant storage tank 2, dosing pipe, intelligent delivery pump, influent water quality sensor group, effluent water quality sensor group, and intelligent controller, the wastewater entering the flocculation reaction tank can be detected, thereby selecting the appropriate flocculant and controlling the dosage.

[0031] Example 2

[0032] like Figure 1-6 As shown, the stirring mechanism includes a hollow stirring shaft 19 in the flocculation reaction tank 1. Both ends of the hollow stirring shaft 19 are connected to the flocculation reaction tank 1 via bearings 20. The outer wall of the hollow stirring shaft 19 is provided with a plurality of evenly distributed stirring blades 21. The stirring blades 21 are connected to the hollow stirring shaft 19 via a driven self-transmission assembly. One end of the hollow stirring shaft 19 extends to the outside of the flocculation reaction tank 1 and is connected to the drive end of the stirring motor 22. The driven self-rotating assembly includes several evenly distributed connecting shafts 23 on the outer wall of the hollow stirring shaft 19. The connecting shafts 23 are connected to the hollow stirring shaft 19 via bearings 24. One end of the connecting shaft 23 is connected to the stirring blade 21, and the other end of the connecting shaft 23 extends into the hollow stirring shaft 19 and is connected to a helical gear 26. A fixing rod 25 is provided on one side of the flocculation reaction tank 1 and located in the bearing 20. One end of the fixing rod 25 extends into the hollow stirring shaft 19. Several evenly distributed helical gears 26 are fixedly sleeved in the hollow stirring shaft 19 and located on the outer wall of the fixing rod 25. A helical gear 27 matching the helical gears 26 is fixedly sleeved on the outer wall of the fixing rod 25. A through hole matching the fixing rod 25 is opened at one end of the hollow stirring shaft 19.

[0033] After the flocculant is added to the flocculation reaction tank 1, the stirring motor 22 is started to drive the hollow stirring shaft 19 to rotate. The hollow stirring shaft 19 drives the stirring blades 21 to revolve and stir the wastewater and flocculant. When the stirring blades 21 revolve, the hollow stirring shaft 19 drives the helical gear 27 to rotate around the helical gear 26 through the connecting shaft 23. Since the helical gear 27 meshes with the helical gear 26, when the helical gear 27 rotates around the helical gear 26, the helical gear 27 will rotate on its own axis. The helical gear 27 drives the stirring blades 21 to rotate on its own axis through the connecting shaft 23. The revolution and rotation of the stirring blades 21 fully stir the wastewater and flocculant. By setting up a stirring mechanism, the wastewater and flocculant can be fully stirred and mixed, so that they can settle quickly and improve the wastewater treatment efficiency.

[0034] In summary, by utilizing the above-mentioned technical solution of the present invention, the wastewater entering the flocculation reaction tank can be detected by setting up a flocculant storage tank 1, a flocculant storage tank 2, a dosing pipe, an intelligent delivery pump, an influent water quality sensor group, an effluent water quality sensor group, and an intelligent controller, thereby selecting a suitable flocculant and controlling the dosage. By setting up a stirring mechanism, the wastewater and flocculant can be fully stirred and mixed, allowing them to settle quickly and improving the wastewater treatment efficiency.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
