Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to an automatic chemical dosing device for a wastewater treatment sedimentation tank and its control system. Background Technique

[0002] A wastewater treatment sedimentation tank is a structure that uses sedimentation to remove suspended solids in water and is a key device for purifying water quality. During the wastewater treatment process, the sedimentation tank removes suspended solids in water by utilizing the natural sedimentation or coagulation sedimentation of water. The sedimentation effect mainly depends on the flow rate of water in the sedimentation tank and the residence time of water in the tank.

[0003] During the wastewater treatment process, the chemical dosing device is one of the key technologies to improve the efficiency and quality of wastewater treatment. In the prior art, common chemical dosing devices generally adopt fixed stirring or mechanical stirring methods. Although these methods can achieve a certain mixing effect, due to their relatively simple design and lack of a dynamic adjustment mechanism, it is difficult to adapt to the mixing requirements under different water quality and flow conditions. For example, when the wastewater flow rate changes, the fixed stirring device may not be able to adjust the stirring intensity and range in time, resulting in too high or too low chemical concentrations in some areas, affecting the treatment effect. In addition, some devices will experience wear or blockage after long-term operation, requiring frequent shutdown for maintenance, increasing the operating cost and downtime.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this application, when the two rotating shafts rotate, the sliding grooves formed on both sides thereof limit the limiting blocks on both sides inside the rotating sleeves, thereby driving the two rotating sleeves to rotate inside the sliders. When the rotating sleeves rotate, they drive the first bevel gears to rotate, causing the first bevel gears to drive the second bevel gears to rotate. The second bevel gears drive the vertical rods to rotate, and further the vertical rods drive the filter cylinders and the cylinders to rotate. When the filter cylinders rotate, the chemicals inside the filter cylinders are thrown out from the mesh holes of the filter cylinders, enabling the chemicals and the wastewater to be fully mixed. At the same time, when the vertical rods rotate, they drive the cylinders to rotate, causing the cylinders to drive the multiple spiral blades on their outer sides to rotate. When the multiple spiral blades rotate, they stir the wastewater, thereby improving the contact effect between the chemicals and the wastewater. At the same time, the vertical rods also drive the first stirring blades at the bottom to rotate, cooperating with the spiral blades to form a vortex in the wastewater, fully mixing the chemicals and the wastewater, and improving the wastewater treatment efficiency.

[0017] 2. In this application, when the rotating shafts rotate, they simultaneously drive the fifth bevel gears to rotate, causing the fifth bevel gears to drive the sixth bevel gears and the reciprocating lead screws to rotate. When the reciprocating lead screws rotate, they drive the rotating rods to rotate. When the rotating rods rotate, they drive the rotating plates to rotate, thereby driving the guide plates to rotate synchronously. When the rotating plates and the guide plates rotate, the guide wheels move along the rotating plates and the guide plates. When the guide plates extend, they push the support plates and the brackets to move reciprocally. When the brackets move reciprocally, they drive the vertical rods and the cylinders to move reciprocally in the horizontal direction. When the two vertical rods and the cylinders move reciprocally, the rotation diameter of the cylinders will continuously change during their revolution, moving in multiple directions inside the water tank to form a turbulent flow, thereby improving the mixing effect of the chemicals and the wastewater.

[0018] 3. During the rotation of the reciprocating lead screw in this application, the reciprocating lead screw drives the threaded rod to move up and down reciprocally. When the threaded rod moves up and down, it drives the rotating disk to move up and down. When the rotating disk descends, it pushes the push rod to move, so that the push rod drives the guide plate to reciprocate outside the rotating plate, thereby continuously changing the outer perimeters of the rotating plate and the guide plate. In this way, the movement trajectory of the support driving the cylinder is kept changing, improving the mixing effect of the medicament and the wastewater, enabling the medicament to be more evenly dispersed in the wastewater, and enhancing the efficiency and quality of wastewater treatment. At the same time, the up and down movement of the rotating disk also drives the sliding of the positioning rod inside the rotating plate to guide the rotating disk, so that the rotating disk, the positioning rod, and the guide plate are synchronized.

[0039] At the bottom ends of the two rotating rods 7, second stirring blades 35 are fixedly connected. At the bottom ends of the two vertical rods 20, first stirring blades 24 are fixedly connected. By driving the second stirring blades 35 to rotate through the rotating rods 7 and driving the first stirring blades 24 to rotate through the vertical rods 20, the second stirring blades 35 and the first stirring blades 24 are rotated to mix the wastewater and the medicament.

[0040] Cavities 38 are provided at the upper and lower ends of the two brackets 16. Inside the four cavities 38 of the two brackets 16, piston plates 39 are slidably connected. At one end of each of the four piston plates 39, a cross bar 40 is fixedly connected. The four cross bars 40 respectively penetrate through both ends of the two brackets 16 and are slidably connected to the two brackets 16. The four cross bars 40 are respectively fixedly connected to one side of the two fixing blocks 5 and the two lower support blocks 37. On the outer sides of the four cross bars 40, tension springs 41 are sleeved. The two ends of the four tension springs 41 are respectively fixedly connected to the two brackets 16 and the two fixing blocks 5 and the lower support blocks 37. In this way, when the bracket 16 moves, it moves relative to the piston plate 39, so that the piston plate 39 forms a damping effect to buffer the bracket 16.

[0041] At both ends of the rotating arm 3, sliding plates 42 are fixedly connected. The two sliding plates 42 are respectively slidably connected to both sides of the top of the pool 1. On the tops of the two sliding plates 42, medicine boxes 43 are fixedly connected. On both sides of the tops of the two sliding plates 42, feeding pumps 44 are fixedly connected. The input ends of the four feeding pumps 44 are respectively communicated with the two medicine boxes 43. The output ends of the four feeding pumps 44 are all fixedly connected with connecting pipes 45. The bottom ends of the four connecting pipes 45 are respectively fixedly connected to the two rotating cover plates 46. The two vertical rods 20 respectively penetrate through the two rotating cover plates 46 and are rotatably connected to the two rotating cover plates 46. At the bottoms of the two sliding plates 42, positive and negative motors 47 are fixedly connected. The output ends of the two positive and negative motors 47 are all fixedly connected with guiding bevel gears 48. A bevel gear ring 49 is fixedly connected to the outside of the pool 1. The two guiding bevel gears 48 are respectively meshed with both sides of the bevel gear ring 49.

[0042] When this solution is in use, the wastewater is discharged into the interior of the water tank 1. By starting the feeding pump 44, the feeding pump 44 outputs the medicament inside the medicament tank 43 from inside the connecting pipe 45, so as to output the medicament from the connecting pipe 45 into the interior of the filter cylinder 21. The medicament flows out from the interior of the filter cylinder 21, and the filter cylinder 21 protects the bottom end of the connecting pipe 45, intercepting the precipitated impurities on the outside and preventing the bottom end of the connecting pipe 45 from being blocked.

[0043] By starting the positive and negative motors 47 on both sides, and making the two positive and negative motors 47 drive the two guide bevel gears 48 to rotate, so as to make the two guide bevel gears 48 move outside the bevel gear ring 49, thereby driving the two slide plates 42 to rotate, and making the two slide plates 42 drive the rotating arm 3 to rotate. When the rotating arm 3 rotates, it drives the support block positioning block 34 and the rotating shaft 4 to rotate. When the two rotating shafts 4 rotate around the fixed shaft 2, the two fourth bevel gears 33 rotate self - rotatably under the meshing and limiting of the third bevel gear 32, so as to make the two fourth bevel gears 33 drive the two rotating shafts 4 to rotate self - rotatably. When the two rotating shafts 4 rotate self - rotatably, the sliding grooves 27 opened on both sides thereof limit the limiting blocks 28 on both sides inside the rotating sleeve 26, so as to drive the two rotating sleeves 26 to rotate inside the slider 25. When the rotating sleeve 26 rotates, it drives the first bevel gear 29 to rotate, making the first bevel gear 29 drive the second bevel gear 30 to rotate, and the second bevel gear 30 drives the vertical rod 20 to rotate, and further makes the vertical rod 20 drive the filter cylinder 21 and the cylinder 22 to rotate. When the filter cylinder 21 rotates, the medicament inside the filter cylinder 21 is thrown out from the mesh holes of the filter cylinder 21, making the medicament and the wastewater fully mixed. At the same time, when the vertical rod 20 rotates, it drives the cylinder 22 to rotate, making the cylinder 22 drive the multiple spiral blades 23 on its outer side to rotate. When the multiple spiral blades 23 rotate, they stir the wastewater, thereby improving the contact effect between the medicament and the wastewater. At the same time, the vertical rod 20 also drives the first stirring blade 24 at the bottom end to rotate, cooperating with the spiral blades 23 to form a vortex in the wastewater, fully mixing the medicament and the wastewater, and improving the wastewater treatment efficiency.

[0044] When the rotating shaft 4 rotates, it simultaneously drives the fifth bevel gear 50 to rotate, making the fifth bevel gear 50 drive the sixth bevel gear 51 and the reciprocating lead screw 6 to rotate. When the reciprocating lead screw 6 rotates, it drives the rotating rod 7 to rotate, and the rotating rod 7 drives the rotating plate 8 to rotate when it rotates, so as to drive the guide plate 9 to rotate synchronously. When the rotating plate 8 and the guide plate 9 rotate, the guide wheel 18 moves along the rotating plate 8 and the guide plate 9. When the guide plate 9 extends, it pushes the support plate 17 and the bracket 16 to move reciprocally. When the bracket 16 moves reciprocally, it drives the vertical rod 20 and the cylinder 22 to move reciprocally in the horizontal direction. When the two vertical rods 20 and the cylinder 22 move reciprocally, the rotation diameter of the cylinder 22 will continuously change during its revolution, moving in multiple directions inside the water tank 1 to form a turbulent flow, so as to improve the mixing effect between the medicament and the wastewater.

[0045] When the reciprocating screw rod 6 rotates, it drives the threaded rod 10 to move up and down reciprocally. When the threaded rod 10 moves up and down, it drives the rotating disk 11 to move up and down. When the rotating disk 11 descends, it pushes the push rod 13 to move, so that the push rod 13 drives the guide plate 9 to reciprocally move outside the rotating plate 8, thereby continuously changing the outer perimeters of the rotating plate 8 and the guide plate 9. In this way, the movement trajectory of the support 16 driving the cylinder 22 is kept changing, improving the mixing effect of the medicament and the wastewater, enabling the medicament to be more evenly dispersed in the wastewater, and improving the efficiency and quality of wastewater treatment. At the same time, through the up and down movement of the rotating disk 11, it also drives the sliding of the positioning rod 12 inside the rotating plate 8 to guide the rotating disk 11, so that the rotating disk 11 and the positioning rod 12 are synchronized with the guide plate 9.

[0046] In addition, during the operation of the equipment, the piston plate 39 slides in the cavity 38 of the support 16, enabling the buffer liquid inside the cavity 38 to flow through the multiple through holes inside the piston plate 39, and cooperating with the damping effect formed by the tension spring 41 to play a buffering role.

[0047] As Figure 13 shown, an automatic chemical dosing control system for a wastewater treatment sedimentation tank includes: a processor 100. The output end of the processor 100 is connected to an initial setting module 200, a sensor module 300, a chemical dosing control module 400, a mixing equipment control module 500, a feedback regulation module 600, and a data analysis and management module 700. The sensor module 300 includes a water quality sensor 301 and a liquid level sensor 302. The output end of the chemical dosing control module 400 is connected to the mixing equipment control module 500. The output end of the mixing equipment control module 500 is connected to the feedback regulation module 600. The output end of the feedback regulation module 600 is connected to the data analysis and management module 700.

[0048] When this solution is in use, the water quality sensor 301 is installed near the inlet and outlet of the sedimentation tank to monitor the water quality parameters of the wastewater in real time, such as chemical oxygen demand COD, biochemical oxygen demand BOD, suspended solids SS, pH value of acidity and alkalinity, etc., providing a data basis for chemical dosing control.

[0049] The liquid level sensor 302 is used to monitor the water level height in the sedimentation tank to prevent the water level from being too high or too low from affecting the wastewater treatment effect. At the same time, it can calculate the wastewater treatment volume in combination with the flow data to assist in determining the chemical dosing amount.

[0050] The feeding pump 44 accurately extracts and doses various medicaments, such as coagulants, coagulant aids, flocculants, etc., according to the instructions of the control system, and has a flow regulation function, enabling flexible control of different chemical dosing amounts.

[0051] Based on the wastewater quality parameters collected by the water quality sensor 301, combined with the preset wastewater treatment process requirements and empirical formulas, the optimal dosage of various chemicals is calculated using intelligent control algorithms such as fuzzy control or PID control. According to the pH value, COD concentration, and flow parameters of the wastewater, the dosing ratio and total amount of the coagulant and flocculant are determined through fuzzy control rules.

[0052] Considering the water volume change in the sedimentation tank, the chemical dosage is adjusted in real time according to the water level information fed back by the level sensor 302 to ensure the uniformity and accuracy of chemical dosing. When the water level rises, the chemical dosage is increased accordingly; when the water level drops, the chemical dosage is reduced to maintain an appropriate chemical concentration, ensuring the wastewater treatment effect while avoiding chemical waste.

[0053] According to the calculated chemical dosage, the PLC sends control commands to the feed pump 44 to adjust the operating frequency or rotation speed of the feed pump 44, realizing precise control of the chemical dosing flow rate. At the same time, monitor the operating status of the feed pump 44, such as parameters like motor current, pressure, and flow rate. When abnormal situations occur, alarm in time and stop the operation of the feed pump 44 to prevent equipment damage and chemical leakage accidents.

[0054] The mixing equipment control module 500 controls the start and stop times of the positive and negative motors 47 to ensure that the chemicals are fully mixed and reacted with the wastewater in the sedimentation tank. According to different chemical characteristics and wastewater treatment stages, adjust the stirring time and intensity to achieve the best mixing effect and flocculation effect. Appropriately increase the stirring speed and extend the stirring time after adding the coagulant to promote the formation of flocs; reduce the stirring speed after adding the flocculant to avoid destroying the formed floc structure.
