Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to an integrated hardness removal and turbidity reduction device. Background Technology

[0002] In the field of water resource treatment, hardness and turbidity are key indicators affecting water quality. Hardness is mainly determined by the content of calcium and magnesium ions in the water. High-hardness water easily leads to pipe scaling, accelerated equipment wear, and affects the stability of industrial production and product quality. Turbidity reflects the concentration of suspended particulate matter in the water. High-turbidity water not only affects sensory experience but may also carry pathogens, threatening drinking water safety. Traditional water treatment processes typically employ a decentralized combination of equipment, such as softening units (ion exchange, chemical precipitation) and sedimentation / filtration units (inclined tube sedimentation tanks, sand filters) operating in stages. However, this approach suffers from problems such as large footprint, complex piping, high operation and maintenance costs, and treatment efficiency significantly affected by fluctuations in water quality.

[0003] Furthermore, in the water treatment process, there is a problem of difficulty in accurately controlling the dosage, as it is impossible to add coagulants specifically based on differences in temperature and turbidity at different locations in the water body. Simultaneously, after addition, coagulants tend to accumulate and are difficult to disperse evenly in the water, affecting the coagulation of impurities. In addition, sensors are prone to being adhered to by impurities in the water during long-term use, leading to inaccurate detection data. Moreover, traditional devices lack the flexibility for component adjustment, easily resulting in coagulant clogging of pipelines, severely impacting the efficiency and effectiveness of hardening and turbidity reduction. Furthermore, if the coagulant is not fully added and fails to effectively coagulate impurities in the water, this will lead to the precipitation of more impurities during subsequent electrolysis, affecting separation and hardening removal. Therefore, an integrated hardening and turbidity reduction device is proposed. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1, such as Figure 1 As shown, this application discloses an integrated hardness removal and turbidity reduction device, including a turbidity reduction tank 100, an electrolysis tank 103, and a filter box 102. The turbidity reduction tank 100, the electrolysis tank 103, and the filter box 102 are connected by a water flow conveying pipe 101. A telescopic sleeve 105 is fixedly connected inside the turbidity reduction tank 100 and the electrolysis tank 103. An inner elastic telescopic bladder 108 is fixedly connected inside the telescopic sleeve 105. An air pump 109 is fixedly connected to both the turbidity reduction tank 100 and the electrolysis tank 103. The inner elastic telescopic bladder 108 is divided into an inner chamber and an outer chamber. The outside of the air pump 109 is connected to the outer chamber of the inner elastic telescopic bladder 108 through a flow diversion structure. A temperature sensor 107 and a turbidity sensor 112 are fixedly connected to the outside of the bottom of the telescopic sleeve 105, respectively. A material discharge structure is connected to the top of the telescopic sleeve 105.

[0030] The material discharge structure includes a metering pump 106, which is fixedly connected to the top of the telescopic sleeve 105. The discharge port of the metering pump 106 is connected to the bottom of the inner elastic telescopic bladder 108.

[0031] Specifically, during use, the water to be treated enters the turbidity reduction tank 100 through the water flow delivery pipe 101. Simultaneously, the filter box 102 and the electrolysis tank 103 maintain a continuous flow through the water flow delivery pipe 101, preparing for subsequent filtration and electrolytic softening processes. During treatment, the air pump 109 on the turbidity reduction tank 100 and the electrolysis tank 103 is activated. The gas generated by the air pump 109 is delivered to the outer chamber of the inner elastic telescopic bladder 108 through a diversion structure. The outer chamber gradually expands due to gas filling, thereby pushing the telescopic sleeve 105, which is fixedly connected to it, to extend and retract vertically inside the turbidity reduction tank 100 and the electrolysis tank 103, adjusting to a height suitable for current water flow detection and reagent addition. Next, the temperature sensor 107 and the turbidity sensor 112, moving synchronously with the telescopic sleeve 105, monitor the water flow at different heights inside the turbidity reduction tank 100. The water flow in the same area is monitored for parameters. Temperature sensor 107 collects water temperature data in real time, and turbidity sensor 112 simultaneously acquires water turbidity data. Both data serve as the basis for adjusting the subsequent coagulant dosage. Based on the detection results fed back by temperature sensor 107 and turbidity sensor 112, metering pump 106 fixed on the top of telescopic sleeve 105 is started to accurately measure the required coagulant. The coagulant is then delivered to the bottom of the inner elastic telescopic bladder 108 through its own outlet, and the coagulant is delivered into the water in the inner chamber and turbidity reduction tank 100. After the coagulant added to the turbidity reduction tank 100 is fully mixed with the water flow, it will coagulate impurities in the water. The water flow containing impurities will then enter the filter box 102 through the water flow delivery pipe 101 for filtration and impurity removal, and then flow into the electrolysis tank 103 for electrolytic softening treatment, completing the complete hardening and turbidity reduction process.

[0032] like Figures 1-9 As shown, the diversion structure includes two three-way valves 110. The two three-way valves 110 are respectively installed at the air outlets of the two air pumps 109. One air outlet of the three-way valve 110 is connected to a first diversion pipe 111. The end of the first diversion pipe 111 away from the three-way valve 110 passes through the outer wall of the telescopic sleeve 105 and is connected to the inner cavity of the outer layer of the inner elastic telescopic bladder 108. The other air outlet of the three-way valve 110 is connected to a second diversion pipe 113. The end of the second diversion pipe 113 away from the three-way valve 110 passes through the outer wall of the telescopic sleeve 105 and is connected to the inner cavity of the inner elastic telescopic bladder 108.

[0033] Specifically, after the entire device is started, first confirm that the two three-way valves 110 are tightly connected to the outlets of the air pumps 109 on the turbidity reduction tank 100 and the electrolysis tank 103, respectively, and that the two ends of the first diversion pipe 111 and the second diversion pipe 113 are correctly connected to the outlets of the three-way valves 110 and the inner and outer chambers of the inner elastic telescopic bladder 108, respectively, to ensure that there is no leakage in the gas path. When it is necessary to adjust the height of the telescopic sleeve 105, control the air pump 109 to start and output gas, and at the same time adjust the three-way valves 111 and 112. The valve core of 0 is turned so that the gas output by the air pump 109 enters the first diversion pipe 111 through one of the outlets of the three-way valve 110. After passing through the outer wall of the telescopic sleeve 105 through the first diversion pipe 111, the gas is delivered to the outer chamber of the inner elastic telescopic bladder 108. The outer chamber gradually expands due to the filling of gas, which in turn pushes the telescopic sleeve 105 to extend and retract up and down in the turbidity tank 100 and the electrolysis tank 103 until it is adjusted to the target height for matching parameter detection and coagulant addition.

[0034] Furthermore, during the process of conveying the coagulant, after the metering pump 106 delivers the coagulant to the inner chamber of the inner elastic telescopic bladder 108, when it is necessary to push the coagulant into the annular conveying pipe 200, the valve core direction is switched by the three-way valve 110 to close the gas delivery passage to the first diversion pipe 111 and open the delivery passage to the second diversion pipe 113. At this time, the gas output by the air pump 109 enters the second diversion pipe 113 through the other outlet of the three-way valve 110 and passes through the outer wall of the telescopic sleeve 105 to the inner chamber of the inner elastic telescopic bladder 108. The air pressure in the inner chamber increases, pushing the coagulant inside towards the inlet of the annular conveying pipe 200 connected to the inner chamber, completing the pushing of the coagulant, and then delivering the coagulant to the interior of the turbidity reducing tank 100 through the outlet of the annular conveying pipe 200.

[0035] Furthermore, once the telescopic sleeve 105 is adjusted to the correct position or the coagulant is pushed out, the air pump 109 is turned off. At the same time, the three-way valve 110 is adjusted to the depressurization state as needed, so that the residual gas in the outer or inner chamber of the inner elastic telescopic bladder 108 flows back to the three-way valve 110 through the first diverter pipe 111 and the second diverter pipe 113, and is then discharged through the exhaust passage of the three-way valve 110, ensuring that the bladder contracts and resets. During use, the inner elastic telescopic bladder 108 will retract to its original state through its own elasticity when it contracts, preparing for the next operation cycle.

[0036] like Figures 3-7 As shown, multiple electrically controlled annular nozzles 700 are connected to the outer chamber of the inner elastic telescopic bladder 108, and the air outlets of the electrically controlled annular nozzles 700 surround the outer periphery of the turbidity sensor 112 and the temperature sensor 107, respectively.

[0037] Specifically, during use, when the data detected by the turbidity sensor 112 and temperature sensor 107 show significant fluctuations compared to normal conditions, and experienced personnel verify that the water quality is the same as before, it is determined that the turbidity sensor 112 and temperature sensor 107 have surface impurities and have reached the preset cleaning cycle. When cleaning is required, the electrically controlled annular nozzle 700 receives a cleaning command and opens. Compressed gas in the outer chamber of the inner elastic telescopic bladder 108 enters each electrically controlled annular nozzle 700 through the connecting channel. After being pressurized by the electrically controlled annular nozzle 700, the gas is ejected from the air outlet surrounding the turbidity sensor 112 and temperature sensor 107, forming an annular airflow that fully covers the detection end surfaces of the turbidity sensor 112 and temperature sensor 107, thereby continuously cleaning the turbidity sensor 112 and temperature sensor 107.

[0038] Furthermore, during the cleaning process, after completing one round of hardening and turbidity reduction, the cleaning command is triggered, and at the same time, the air pump 109 continuously supplies air to the outer chamber of the inner elastic telescopic bladder 108 to ensure sufficient cleaning air supply.

[0039] Furthermore, when the device is normally performing water parameter detection and coagulant addition, the electrically controlled annular nozzle 700 is in the closed state. At this time, the gas in the outer chamber of the inner elastic telescopic bladder 108 is only used to drive the telescopic sleeve 105 to rise and fall. The electrically controlled annular nozzle 700 does not participate in airflow distribution and only waits around the two sensors.

[0040] like Figure 6 As shown, an electrode plate 800 is installed at the bottom of the telescopic sleeve 105 located inside the electrolysis tank 103.

[0041] Specifically, during use, the water, after being treated with coagulant in the turbidity reduction tank 100 and filtered by the filter box 102, enters the electrolysis tank 103 through the water delivery pipe 101. Prior to this, the telescopic sleeve 105 inside the electrolysis tank 103 has been adjusted to the appropriate height under the drive of the air pump 109. The electrode plate 800, fixed at the bottom of the telescopic sleeve 105, is simultaneously positioned and fully immersed in the water flow, preparing for electrolysis. When the water flow fills the electrolysis tank 103 and reaches the preset liquid level, the power supply system of the electrode plate 800 is activated. After the electrode plate 800 is energized, an electrolytic reaction is generated, decomposing minerals such as calcium and magnesium ions in the water that cause excessive hardness. These ions are precipitated or transformed into easily separable substances, thereby reducing the hardness of the water.

[0042] Furthermore, during the electrolysis process, if it is necessary to optimize the electrolysis effect, the air pressure in the outer chamber of the inner elastic telescopic bladder 108 can be adjusted by the air pump 109, driving the telescopic sleeve 105 to rise and fall slightly, thereby driving the electrode plate 800 to perform electrolysis at different water depths, ensuring that all areas of the water can react fully, improving the overall softening uniformity. During the electrolysis process, the turbidity sensor 112 and temperature sensor 107 located inside the electrolysis tank 103 will continuously detect the temperature and turbidity at different locations inside the electrolysis tank 103, so as to adjust the position of the electrode plate 800.

[0043] like Figures 1-9 As shown, an exhaust control valve 900 is fixedly connected to the outside of the telescopic sleeve 105. The exhaust control valve 900 is connected to the inner chamber of the inner elastic telescopic bladder 108. A stirrer 104 is installed on both the turbidity reduction tank 100 and the electrolysis tank 103.

[0044] Specifically, during use, when the coagulant is fully pushed into the annular delivery pipe 200, and the inner chamber pressure is no longer required, or when the inner elastic expansion bladder 108 needs to be contracted, a pressure relief command is triggered. Upon receiving the command, the exhaust control valve 900 opens, and the residual gas in the inner chamber of the inner elastic expansion bladder 108 is quickly discharged through the connecting channel via the exhaust control valve 900. The chamber pressure drops to normal pressure. After the gas is completely discharged, the exhaust control valve 900 closes, and the inner elastic expansion bladder 108 contracts and resets under its own elasticity.

[0045] Specifically, after the water flows into the electrolysis tank 103 or the turbidity reduction tank 100, the agitator 104 on the electrolysis tank 103 is turned on. The agitator 104 is a drive motor at the top. The drive motor is connected to the coupling and the stirring rod. The drive motor will work with the coupling to drive the stirring rod to slowly stir the water, so that all areas of the water can fully contact the electrode plate 800 or the coagulant, avoiding insufficient local electrolysis or insufficient mixing of the coagulant. At the same time, it promotes the uniform distribution or settling of the precipitates produced by electrolysis, and improves the softening effect of hard water.

[0046] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the telescopic sleeve 105 and the inner elastic telescopic bladder 108 can flexibly adjust the height of the telescopic sleeve 105, which not only drives the temperature sensor 107 and turbidity sensor 112 at the bottom to perform comprehensive parameter detection on the water at different heights and in different areas within the turbidity reduction tank 100, providing accurate data support for coagulant dosing, but also adapts to the treatment needs of different water depths. The metering pump 106 fixed at the top of the telescopic sleeve 105 can accurately measure the amount of coagulant based on the sensor feedback data, and then achieve accurate delivery and dosing of the agent through communication with the inner elastic telescopic bladder 108, effectively avoiding the problem of agent waste or insufficient dosing, ensuring that the coagulant and water are fully mixed and impurities are efficiently coagulated, and the subsequent connection process of filtration by the filter box 102 and softening by the electrolysis tank 103 further ensures the quality of the effluent.

[0047] Example 2: Considering that during use, when coagulant is added solely using the inner elastic expansion bladder 108, the coagulant can mostly only be transported through this single channel. However, the turbidity varies at different locations within the turbidity reduction tank 100. Adding coagulant to a single location may result in excessive coagulant dosage at that location or insufficient dosage in other areas, leading to uneven turbidity reduction. To address these technical problems, this application proposes the following technical solution:

[0048] like Figures 2-4 As shown, the feeding structure also includes an annular conveying pipe 200, which is fixedly connected to the bottom of the telescopic sleeve 105. The outer bottom wall of the annular conveying pipe 200 is connected to multiple feeding electric control valves 201, and the feed inlet of the annular conveying pipe 200 is connected to the inner chamber of the inner elastic telescopic bladder 108.

[0049] Specifically, during use, the metering pump 106 delivers the precisely metered coagulant to the inner chamber of the inner elastic telescopic bladder 108. Under the pressure of the gas delivered by the air pump 109 through the diversion structure, the inner chamber pushes the coagulant to the inlet of the connected annular conveying pipe 200. The coagulant enters the annular conveying pipe 200 along the inlet for temporary storage. At the same time, the annular structure of the annular conveying pipe 200 achieves the initial dispersion of the coagulant. Since the annular conveying pipe 200 is fixed to the bottom of the telescopic sleeve 105, when the air pump 109 drives the outer chamber of the inner elastic telescopic bladder 108 to expand and adjust the height of the telescopic sleeve 105 in the early stage, the annular conveying pipe 200 has moved synchronously with the telescopic sleeve 105 to the appropriate addition height in the turbidity reduction tank 100, ensuring that the feeding solenoid valve 201 can correspond to the key areas of the water body.

[0050] Furthermore, by combining the water parameters of different areas within the turbidity reduction tank 100 detected by the temperature sensor 107 and the turbidity sensor 112, multiple feeding solenoid valves 201 are specifically controlled. In areas with high turbidity requiring more coagulant, the corresponding feeding solenoid valve 201 is fully or fully opened; in areas with clearer water, the corresponding feeding solenoid valve 201 is opened slightly or closed. This allows for the on-demand, zoned delivery of coagulant. The coagulant, delivered to the turbidity reduction tank 100 through the feeding solenoid valve 201, directly acts on the corresponding water area. Subsequently, the agitator 104 on the turbidity reduction tank 100 rotates and stirs, accelerating the uniform mixing of the coagulant and water, promoting rapid coagulation of impurities in the water, and laying the foundation for subsequent filtration and impurity removal.

[0051] Furthermore, during use, gas can be continuously supplied to the interior of the annular delivery pipe 200 through the second diversion pipe 113, thereby continuously blowing the coagulant delivered to the interior of the annular delivery pipe 200 through the inner elastic expansion bladder 108 into different positions within the annular delivery pipe 200.

[0052] like Figure 5 As shown, a triangular material distribution plate 600 is fixedly connected to the inner bottom wall of the annular conveying pipe 200. The triangular material distribution plate 600 is located directly below the discharge port of the inner elastic telescopic bladder 108.

[0053] Specifically, during use, when the inner chamber of the inner elastic expansion bladder 108 pushes the coagulant from the outlet to the annular conveying pipe 200 under the action of gas pressure, the coagulant falls directly and impacts the arc-shaped top of the triangular distribution plate 600. With the help of the triangular structure and arc-shaped design of the top of the triangular distribution plate 600, the coagulant is evenly distributed to both sides, avoiding concentrated accumulation in a certain area inside the annular conveying pipe 200.

[0054] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, the height of the annular conveying pipe 200 is adjusted synchronously with the telescopic sleeve 105 to ensure that the dosing position is adapted to the key areas of the water body in the turbidity reduction tank 100. The distribution of multiple feeding electric control valves 201 on the bottom wall of the annular conveying pipe 200, together with the regional parameter detection of the temperature sensor 107 and the turbidity sensor 112, enables targeted control of different turbidity areas. By opening or closing the corresponding valves with full or small opening, the coagulant can be added in zones as needed, avoiding the situation of too much or too little agent in a single location. At the same time, the gas continuously conveyed by the second diversion pipe 113 can further blow the coagulant in the annular conveying pipe 200 to different locations. Combined with the stirring action of the agitator 104, the uniformity of the mixing of coagulant and water body is improved, ensuring that the water body in each area of ​​the turbidity reduction tank 100 can receive the appropriate amount of coagulant, thereby ensuring the consistency and stability of the turbidity reduction effect.

[0055] Example 3: Considering that the coagulant entering the annular conveying pipe 200 is delivered to different locations within the annular conveying pipe 200 by gas blowing, and that during the gas conveying process, the continuous gas delivery will concentrate the coagulant to the same location, making it impossible to uniformly deliver the coagulant to various locations, this application proposes the following technical solution to address the above-mentioned technical problems:

[0056] like Figures 4-8 As shown, the inner bottom wall of the annular conveying pipe 200 is integrally formed with multiple soft adjusting blocks 300, and an adjusting baffle 301 is fixedly connected to the inner center of the soft adjusting block 300. The inner bottom wall of the annular conveying pipe 200 is integrally formed with multiple gathering grooves 302, and the feeding electric control valve 201 is located at the cone tip of the gathering groove 302.

[0057] Specifically, during use, when the coagulant is diverted by the triangular distribution plate 600 and diffuses along the bottom wall of the annular conveying pipe 200, it will encounter multiple regulating baffles 301. The inclined structure of the regulating baffles 301 forms a moderate obstruction to the flowing coagulant, preventing it from accumulating in a certain direction due to airflow or gravity. At the same time, the soft regulating block 300 can deform slightly with the flow rate of the coagulant, indirectly adjusting the inclination angle of the regulating baffles 301 to ensure that the coagulant is evenly dispersed throughout the annular conveying pipe 200.

[0058] Furthermore, the dispersed coagulant continues to flow within the annular conveying pipe 200, gradually entering the corresponding agglomeration trough 302. The conical structure of the agglomeration trough 302 forms a guiding channel, converging the surrounding dispersed coagulant towards the cone tip. The feeding solenoid valve 201 is located at the cone tip, ensuring that the coagulant can be accurately converged to the valve inlet, avoiding material shortage in the valve due to coagulant dispersion. When the feeding solenoid valve 201 is opened according to the water body parameter detection results, the coagulant after converging in the agglomeration trough 302 can be quickly and stably delivered to the corresponding area of ​​the turbidity reduction tank 100 through the valve. This ensures delivery efficiency and, in conjunction with the uniform distribution effect of the adjusting baffle 301, achieves uniform and quantitative delivery of the coagulant, providing a guarantee for subsequent impurity coagulation.

[0059] Considering that coagulant will continuously accumulate around the regulating baffle 301 while it is continuously in existence, and that once the coagulant causes blockage, it will be impossible to deliver the coagulant evenly to various locations, the following solution is proposed:

[0060] like Figure 8 As shown, a magnetic block 400 is fixedly connected to the outside of the adjusting baffle 301, and a lower electromagnet 401 is fixedly connected to the inside of the soft adjusting block 300.

[0061] Specifically, during use, before startup, the lower electromagnet 401 is de-energized and does not generate attraction force. The adjusting baffle 301, under the elastic support of the soft adjusting block 300, maintains the preset initial tilt angle. The magnetic block 400 is in a natural state with the adjusting baffle 301, preparing for the initial flow of coagulant. When the coagulant enters the annular conveying pipe 200 after being diverted by the triangular dividing plate 600, if the coagulant flow is large and has a tendency to accumulate, or if the flow is small and needs to be reduced, the lower electromagnet 401 is activated and its current is adjusted. After the lower electromagnet 401 is energized, it generates magnetism and generates attraction force on the magnetic block 400 outside the adjusting baffle 301. By changing the current intensity, the magnitude of the attraction force is controlled, thereby driving the adjusting baffle 301 to rotate around the support point of the soft adjusting block 300, adjusting the tilt angle.

[0062] Furthermore, when the flow rate is high, the attraction force of the lower electromagnet 401 is increased, causing the tilt angle of the regulating baffle 301 to decrease, reducing the obstruction strength of the coagulant and preventing local accumulation. When the flow rate is low, the attraction force is decreased, and the tilt angle of the regulating baffle 301 is increased, enhancing the flow guiding effect and ensuring uniform dispersion of the coagulant. If coagulant accumulates around the regulating baffle 301, the attraction force can be alternately increased or decreased to cause the regulating baffle 301 to swing slightly, shaking off the attached coagulant and preventing blockage. When one round of coagulant delivery is completed or the flow rate stabilizes, the current of the lower electromagnet 401 is adjusted to its initial state, the attraction force returns to its initial value, and the regulating baffle 301 returns to the preset angle under the elastic reset action of the soft regulating block 300. The lower electromagnet 401 can repeat the above adjustment process according to subsequent changes in the coagulant flow rate to achieve dynamic adaptation and continuously ensure uniform dispersion of the coagulant.

[0063] like Figure 8 As shown, the inner top wall of the annular conveying pipe 200 is provided with multiple upper clamping grooves 500, and an upper electromagnet 501 is fixedly connected to the inner top wall of the upper clamping groove 500.

[0064] Specifically, during normal coagulant delivery, the upper electromagnet 501 is de-energized and does not generate adsorption force. At this time, the regulating baffle 301 inside the annular delivery pipe 200 maintains its preset working posture, and the coagulant can flow smoothly. When it is necessary to pause coagulant addition, switch delivery paths, or perform equipment maintenance or troubleshooting, the system issues a shutdown command to activate the corresponding upper electromagnet 501. After the upper electromagnet 501 is energized, it generates magnetic attraction, which forms an upward adsorption force on the corresponding regulating baffle 301 below. Under the action of attraction, the regulating baffle 301 overcomes its own weight and support resistance, moves upward, and gets stuck in the corresponding upper locking groove 500. Its top is tightly fitted with the inner wall of the upper locking groove 500, achieving a sealing blockage of the corresponding area or the entire passage, thereby directly blocking the delivery of gas inside the annular delivery pipe 200.

[0065] Example:

[0066] Eight regulating baffles 301 are set according to requirements. These eight baffles 301 are evenly arranged along the inner wall of the annular conveying pipe 200, numbered 1-8, corresponding to eight equal zones within the turbidity reduction tank 100. Each baffle is equipped with an independent magnetic block 400 and a lower electromagnet 401, and is associated with the corresponding zone's feeding control valve 201 and temperature or turbidity detection data. This forms an independent control unit consisting of one baffle, one lower electromagnet 401, one zone detection data, and one feeding control valve 201. Initially, all lower electromagnets 401 are de-energized. The eight regulating baffles 301 maintain an initial tilt angle of 30° under the elastic support of the soft regulating block 300, ensuring unobstructed initial flow of the coagulant. After detection by the temperature sensor 107 and turbidity sensor 112 along with the telescopic sleeve 105, the data for each zone are fed back as follows:

[0067] Zones 1, 3, 5, and 7: Turbidity of 25 NTU and temperature of 28°C are considered high turbidity requirements, necessitating the addition of more coagulant.

[0068] Zones 2, 4, 6, and 8: Turbidity 12 NTU, temperature 25℃, low turbidity requirement, require less coagulant addition;

[0069] Global coagulant delivery flow rate: 5 L / min (medium flow rate);

[0070] High turbidity zones 1, 3, 5, and 7: Activate the corresponding lower electromagnet 401, apply a 0.3A current to generate a moderate adsorption force, adjust the tilt angle of baffle 301 to reduce the obstruction of the coagulant, and allow more coagulant to flow quickly to the corresponding agglomeration tank 302. In conjunction with the full opening of the feeding electric control valve 201, increase the dosage.

[0071] Low turbidity zones 2, 4, 6, and 8: A weak current of 0.1A is passed through the corresponding electromagnet 401, resulting in a small adsorption force. The tilt angle of the baffle 301 is adjusted to maintain 25° to moderately block the flow rate of the coagulant, reducing the amount of coagulant flowing to the aggregation tank 302. The feeding electric control valve 201 is opened to a small degree to control the dosage.

[0072] When the coagulant flow rate in the process suddenly increases to 8 L / min, which is a high flow rate, the following adjustments should be made:

[0073] All lower electromagnets 401 will have their current increased by 0.1A, with 0.4A for high turbidity zones and 0.2A for low turbidity zones.

[0074] The angles of baffles 1, 3, 5, and 7 were further reduced to 10°, and the angles of baffles 2, 4, 6, and 8 were reduced to 20° to avoid coagulant accumulation under high flow rates, while maintaining the same addition ratio in each zone.

[0075] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, the regulating baffle 301 supported by the soft regulating block 300 forms a moderate obstruction to the flowing coagulant through the inclined structure. With the slight deformation of the soft regulating block 300 with the flow rate, the tilt angle of the baffle can be indirectly adjusted, effectively preventing the coagulant from accumulating due to airflow or gravity, and achieving uniform dispersion in the annular conveying pipe 200. At the same time, the magnetic suction block 400 outside the regulating baffle 301 cooperates with the lower electromagnet 401 inside the soft regulating block 301. The magnitude of the adsorption force can be controlled by changing the current intensity, and the tilt angle of the baffle can be dynamically adjusted to adapt to different coagulant flow rates. It can also drive the baffle to swing slightly by alternating the increase and decrease of the adsorption force, shaking off the attached coagulant and completely solving the blockage problem.

For those skilled in the art, the present invention can have various modifications and variations. 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.
