Detailed Implementation

[0021] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This invention provides a fully automated coagulation and chemical dosing water treatment device, such as... Figures 1 to 9 As shown, the device includes a frame 10 and an electrical control box 20. The frame 10 is equipped with a raw water turbidity measurement component 30, a reaction component 40, and a dosing component 50. Multiple reaction components 40 are arranged in a matrix. The raw water turbidity measurement component 30 is installed on the raw water inlet pipe and is used to measure the turbidity of the raw water that is about to be injected into the reaction component 40. The dosing component 50 is used to add a preset amount of reagent to each reaction component 40. Each reaction assembly 40 includes a reaction cup 41, on which a stirring motor 42 is installed. A stirring paddle 43 for stirring the raw water and reagents in the reaction cup 41 is fixedly installed on the output shaft of the stirring motor 42. A supernatant turbidity meter 60 is installed on the dosing assembly 50 for measuring the turbidity of the supernatant after the coagulation reaction of the raw water in the reaction cup 41.

[0025] It should be noted that the fully automated coagulation and chemical dosing water treatment device provided by this invention integrates a raw water turbidity measurement component 30, a chemical dosing component 50, and multiple reaction components 40 on the frame 10. This allows for the automatic completion of the entire process, including raw water testing, chemical dosing, stirring reaction, and supernatant turbidity measurement, significantly reducing manual operation and improving experimental efficiency. This treatment device can simultaneously conduct parallel experiments on multiple reaction components 40. By real-time monitoring and comparison of the coagulation effects with different dosages, the optimal dosage can be determined in a shorter time, shortening the experimental cycle from several hours. The real-time monitoring functions of the raw water turbidity meter 32 and the supernatant turbidity meter 60 automatically collect and record changes in water quality before and after coagulation, providing objective data support for coagulation effect analysis and subsequent water treatment. Therefore, this invention solves the problem of long experimental cycles in existing technologies for determining the optimal dosage in water coagulation experiments.

[0026] It should also be noted that this invention is a fully automated coagulation and chemical dosing water treatment device. This invention provides a complete, unmanned system for coagulation experiments in water treatment, automatically detecting, automatically adding chemicals, automatically conducting comparative experiments, and outputting the optimal dosage to guide water treatment. Under normal operation, this invention can produce results within one hour. When water quality changes significantly, this invention can quickly provide water treatment results with the correct dosage in approximately 30 minutes, guiding water plants to adjust their water treatment strategies in a timely manner.

[0027] like Figures 1 to 7 As shown, the reaction cup 41 includes a cup body 411 and a cup lid 412 connected to each other. The cup body 411 is rectangular in shape and its inner bottom wall is spherically concave. A stirring motor 42 is mounted on the cup lid 412. A waterproof ring 44 is fitted onto the output shaft of the stirring motor 42 and abuts against the cup lid 412. The cup lid 412 has a dosing port 4121 that communicates with the internal cavity of the cup body 411. In this embodiment, the cup body 411 and the cup lid 412 are fastened together by screws. The cup lid 412 has a sealing groove 4122. The waterproof ring 44 is located in the sealing groove 4122. The outer wall of the waterproof ring 44 has an annular groove 441. The cross-section of the annular groove 441 is V-shaped or U-shaped.

[0028] In specific implementation, a waterproof ring 44 is set between the cup lid 412 and the stirring motor 42, and a sealing groove 4122 is formed on the cup lid 412. The waterproof ring 44 is embedded in the sealing groove 4122, which improves the sealing performance at the joint between the cup lid 412 and the stirring motor 42, effectively preventing liquid leakage during the stirring reaction and ensuring the cleanliness and safety of the experimental environment. Because the outer wall of the waterproof ring 44 has an annular groove 441 with a V-shaped or U-shaped cross-section, the waterproof ring 44 has good deformation space under axial pressure, thereby achieving better elastic fit and sealing effect, further improving the waterproof reliability of the device under long-term operation. Since the inner bottom wall of the cup body 411 is a spherical concave surface, it can reduce dead zones in the fluid during stirring, promote the uniform mixing of raw water and reagents in the reaction cup 41, thereby improving the coagulation reaction efficiency and the accuracy of experimental results.

[0029] like Figures 5 to 7 As shown, the side wall of the cup body 411 is provided with a first liquid inlet 4111 and a first overflow outlet 4112 arranged adjacent to each other, and the bottom of the cup body 411 is provided with a first liquid outlet 4113. The first liquid inlet 4111, the first liquid outlet 4113 and the first overflow outlet 4112 are all connected to the internal cavity of the cup body 411.

[0030] In practical implementation, since both the first inlet 4111 and the first outlet 4113 are connected to the internal cavity of the cup body 411, automatic injection of raw water and automatic discharge of liquid after coagulation reaction can be achieved, reducing manual intervention and improving the automation level of the experimental process. By setting a first overflow port 4112 adjacent to the first inlet 4111 on the side wall of the cup body 411, the liquid level can be automatically maintained constant during the reaction process, preventing excessive liquid injection or overflow of reaction liquid, thereby ensuring that the liquid volume in each reaction cup 41 is consistent and improving the comparability and repeatability of experimental results.

[0031] like Figures 1 to 9 As shown, the first inlet 4111 is connected to the inlet pump via a pipeline, which is used to inject raw water into each reaction cup 41. The first overflow port 4112 is connected to the overflow pump via a pipeline, and the first outlet 4113 is connected to the waste discharge pump via a pipeline. In this embodiment, ball valves are installed between the reaction cup 41 and the pipelines of the inlet pump and the waste discharge pump, respectively, and pinch valves are installed between the reaction cup 41 and the pipeline of the overflow pump.

[0032] In practical implementation, by connecting the inlet pump, overflow pump, and waste discharge pump to the first inlet 4111, first overflow 4112, and first outlet 4113 respectively, the water inlet, overflow, and waste discharge operations of the reaction cup 41 can be automatically completed without manual intervention, significantly improving the automation level and work efficiency of the experiment. By installing ball valves between the reaction cup 41 and the inlet and waste discharge pumps, and pinch valves between the reaction cup 41 and the overflow pump, the inlet, discharge, and overflow processes of each reaction cup 41 can be independently controlled, enabling parallel or individual operation of multiple coagulation experiments with flexible operation. The valves also serve to prevent backflow and isolate the liquid system, avoiding cross-flow or contamination between different reaction cups 41, ensuring the independence and data accuracy of each experimental group, and preventing damage to the equipment from backflow when the pump stops.

[0033] like Figure 1 As shown, the number of reaction components 40 is set to 9, and the 9 reaction components 40 are arranged in 3 rows and 3 columns. The height of the three rows of reaction components 40 along the Z-axis is different, while the height of each reaction component 40 in the same row along the Z-axis is the same.

[0034] In practical implementation, the nine reaction components 40 are arranged in a matrix of three rows and three columns, with the three rows of reaction components 40 having different heights along the Z-axis. This makes the overall structure of the device more compact and rational, making full use of three-dimensional space and reducing the equipment's footprint. The layered layout with different heights facilitates smoother arrangement of the inlet, dosing, overflow, and drain pipelines between the reaction components 40, avoiding pipeline crossings and improving the ease of assembly and maintenance. Because the three rows of reaction components 40 are arranged at different heights, it is convenient for experimental personnel to observe the coagulation reaction and liquid level changes in each reaction cup 41 during operation. It also facilitates the inspection or replacement of individual reaction components 40, improving equipment safety and maintenance efficiency. The nine reaction components 40 can simultaneously conduct coagulation experiments under different dosages or conditions, enabling parallel comparative testing of multiple samples, significantly shortening the experimental cycle, and quickly outputting data on the optimal dosage and coagulation effect of the raw water.

[0035] like Figures 1 to 3 As shown, the dosing assembly 50 includes a dosing needle 51, an injection pump 52, and a moving part. The dosing needle 51 and the injection pump 52 are connected by pipelines. The dosing needle 51 is used to inject the reagent into the reaction cup 41. The injection pump 52 is mounted on the table of the frame 10. The moving part is used to drive the dosing needle 51 and the supernatant turbidimeter 60 to move along the XYZ axis.

[0036] In practice, the dosing assembly 50 is connected to the dosing needle 51 via the syringe pump 52, enabling it to automatically and quantitatively inject reagents into each reaction cup 41 according to a set program. This avoids measurement errors caused by manual dosing and achieves precise control of reagent dosing. The dosing needle 51 is driven to move along the XYZ axes by a moving component, allowing the same dosing assembly 50 to sequentially dosing multiple reaction assemblies 40. This eliminates the need for a separate dosing device for each reaction cup 41, simplifying the structure, reducing costs, and improving equipment versatility. The moving component not only drives the dosing needle 51 but also moves the supernatant turbidity meter 60 between different reaction cups 41, enabling the sharing and automatic switching of dosing and detection functions, improving detection efficiency and the integration level of the device. Due to the high control precision of the syringe pump 52, precise injection of trace amounts of reagent can be achieved. Combined with the accurate movement of the moving component, this ensures consistent dosing amounts in each reaction cup 41, thereby improving the repeatability and data reliability of the coagulation experiment.

[0037] like Figures 1 to 3As shown, the moving parts include a second moving module 54, a first moving module 53, and a third moving module 55 connected in sequence. The first moving module 53 drives the third moving module 55 to move along the X-axis. The second moving module 54 is connected to the frame 10 and drives the first moving module 53 and the third moving module 55 to move along the Y-axis. The third moving module 55 drives the dosing needle 51 and the supernatant turbidimeter 60 to move along the Z-axis. In this embodiment, the first moving module 53, the second moving module 54, and the third moving module 55 are all structures known in the art, and their specific structures will not be described in detail.

[0038] In practical implementation, a three-axis linkage structure consisting of a first moving module 53, a second moving module 54, and a third moving module 55 is set up, enabling the dosing needle 51 and the supernatant turbidimeter 60 to move independently and precisely in the XYZ directions. This achieves accurate positioning and automatic dosing and detection operations for multiple reaction components 40. The three-axis movement design allows for rapid switching between multiple reaction cups 41 under program control, eliminating the need for manual movement or adjustment, significantly improving dosing and detection efficiency, and shortening the coagulation experiment cycle. Through the coordinated work of each moving module, highly repeatable and high-precision displacement control can be achieved in three-dimensional space, ensuring the accuracy of the injection position of the dosing needle 51 and the sampling position of the supernatant turbidimeter 60, thereby improving the reliability and consistency of experimental data.

[0039] like Figure 1 and Figure 4 As shown, the raw water turbidity measurement assembly 30 includes a turbidity box 31 connected to the raw water inlet pipeline, and a raw water turbidity meter 32 for measuring the turbidity of the raw water inside the turbidity box 31 is installed on the turbidity box 31. In this embodiment, the turbidity box 31 includes a box body 311 and a box cover 312. The box body 311 is connected to the raw water inlet pipeline, and one end of the raw water turbidity meter 32 passes through the box cover 312 and is embedded in the box body 311. A sealing ring 33 is installed between the box body 311 and the box cover 312.

[0040] In practice, a turbidity box 31 connected to the raw water inlet pipe is installed, and a raw water turbidity meter 32 is installed inside the turbidity box 31. This allows for real-time detection of the turbidity of the raw water before it enters the reaction assembly 40, ensuring the accuracy of the parameters for the coagulation experiment water and providing reliable data support for subsequent dosing control. The turbidity box 31 consists of a box body 311 and a box cover 312, with a sealing ring 33 between them. This effectively prevents liquid leakage and the entry of external gases, ensuring the airtightness of the turbidity measurement environment, avoiding measurement errors, and improving measurement stability. Because the box body 311 is directly connected to the raw water inlet pipe, the liquid flow is continuous and smooth, without the formation of stagnant areas or bubble interference, which helps to obtain more stable and accurate raw water turbidity detection results.

[0041] like Figure 1 and Figure 8 As shown, the system also includes a cleaning tank 70. An inlet pump is used to inject cleaning fluid into the reaction cup 41 and the cleaning tank 70. The cleaning tank 70 is used to clean the supernatant turbidity meter 60 after supernatant turbidity measurement. The cleaning tank 70 has spaced-apart cleaning chambers 71 and overflow chambers 72. The cleaning tank 70 has a second inlet 73, a second outlet 74, and a second overflow port 75. The second inlet 73 and the second outlet 74 communicate with the cleaning chamber 71, and the second overflow port 75 communicates with the overflow chamber 72. In this embodiment, the second inlet 73 is located on the side wall of the cleaning tank 70, the second outlet 74 and the second overflow port 75 are located at the bottom of the cleaning tank 70. The second inlet 73 is connected to the inlet pump via a pipeline, the second outlet 74 is connected to the waste discharge pump via a pipeline, and the second overflow port 75 is connected to the overflow pump via a pipeline.

[0042] In practical implementation, a cleaning tank 70 is set up, and a liquid inlet pump injects cleaning solution into the cleaning tank 70 and the reaction cup 41. This allows for automatic cleaning after the supernatant turbidity meter 60 completes its detection, avoiding manual cleaning and improving the system's automation and operational efficiency. Because the cleaning tank 70 cleans the supernatant turbidity meter 60 promptly, it effectively removes residual impurities and reagents from the probe surface, preventing the previous sample from affecting the next measurement result, thereby improving the accuracy and repeatability of turbidity detection. By setting a second inlet 73, a second outlet 74, and a second overflow port 75 on the cleaning tank 70, which are connected to the inlet pump, waste pump, and overflow pump pipelines respectively, the injection, discharge, and overflow control of the cleaning solution are achieved, ensuring a smooth fluid path without blockages or backflow during the cleaning process, and ensuring safe and stable operation. The automatic cleaning mechanism reduces deposition and corrosion on the turbidity meter probe surface, lowers the frequency of manual cleaning, thereby extending the service life of the supernatant turbidity meter 60 and improving the long-term stability of the entire system.

[0043] Working Principle: During operation, the inlet pump sequentially draws raw water into nine reaction cups 41. The raw water turbidity measuring component 30 in the liquid path measures the turbidity of the raw water. Based on the measured turbidity value and the raw water volume, the dosage is calculated. The moving part drives the dosing needle 51 to add the reagent sequentially into the nine reaction cups 41. The dosage is precisely controlled by the injection pump 52. After the dosing is completed, the stirring paddle 43 in the reaction cups 41 simultaneously starts to perform rapid and slow stirring, making the reagent more evenly mixed and forming a colloidal substance (flocculation). The raw water mixture is left to stand for a period of time, allowing the colloidal substance (flocculation) to accumulate at the bottom of the reaction cups 41 and form layers. The upper layer of the reaction cups 41 is the supernatant, and the lower layer is the floc. The supernatant turbidity meter 60, driven by the moving part, sequentially measures multiple points of the supernatant in the nine reaction cups 41. When the dosage of the drug added to the 9 reaction cups 41 increases or decreases sequentially, a more scientific and reasonable drug addition plan can be provided by measuring the turbidity of the supernatant.

[0044] In addition, the inlet pump sequentially draws tap water into the nine reaction cups 41, and the stirring motor 42 drives the stirring paddle 43 to rotate, thereby cleaning the reaction cups 41. After the supernatant turbidity meter 60 completes the measurement, the inlet pump simultaneously adds tap water to the cleaning tank 70. Under the movement of the moving parts, the supernatant turbidity meter 60 is moved into the cleaning tank 70, and the self-cleaning function of the supernatant turbidity meter 60 is activated, completing the cleaning of the supernatant turbidity meter 60.

[0045] For example, the fully automated coagulation and chemical dosing water treatment device provided in this embodiment of the invention has the following specific working process: Raw water inlet procedure: Pressing the device start button opens the raw water ball valve, and the raw water is first pumped into the raw water turbidity measuring component 30 by the inlet pump. After standing for 1 minute, the raw water turbidity value is measured as 5 NTU by the raw water turbidity meter 32 (this value is for illustrative purposes only). Simultaneously, the inlet ball valves open sequentially, and the inlet pump pumps the raw water into reaction cups 41 (numbers 1 to 9), with a raw water volume of 1.5L. At the same time, the overflow pump opens, and the nine pinch valves open sequentially, causing mechanical overflow in reaction cup 41.

[0046] Dosing of the drug: Based on preliminary calculations, the dosage is approximately 50 µL (this value is for illustrative purposes only). Using 50 µL as the baseline dosage, increments or decrements of 5 µL are used (this value is for illustrative purposes only). The drug is sequentially drawn using the syringe pump 52, and the moving part drives the dosing needle 51 to move, adding 30 µL to reaction vessel 1, 35 µL to reaction vessel 2, 40 µL to reaction vessel 3, 45 µL to reaction vessel 41, 50 µL to reaction vessel 5, 55 µL to reaction vessel 6, 60 µL to reaction vessel 7, 65 µL to reaction vessel 8, and 70 µL to reaction vessel 9.

[0047] Stirring and settling: After the chemical addition is completed, the nine stirring motors 42 drive the corresponding nine stirring paddles 43 to stir rapidly for 1 minute and then slowly for 5 minutes. The chemical reacts with the raw water to form a gel-like substance (alum floc). The mixture is allowed to stand for 20 minutes to allow the gel-like substance and the supernatant to separate into layers. In the reaction vessel 41, the upper layer is the supernatant and the lower layer is the gel-like substance (alum floc).

[0048] Supernatant turbidity measurement: The moving part drives the supernatant turbidity meter 60 to move, and the third moving module 55 drives the supernatant turbidity meter 60 to probe to 1 / 3 of the original water volume below the liquid surface of the reaction cup 41, and supernatant turbidity is measured at multiple locations.

[0049] Cleaning of the supernatant turbidity meter 60: Open the cleaning inlet ball valve, and the inlet pump adds 90mL of tap water into the cleaning chamber 71 of the cleaning tank 70. The moving part drives the supernatant turbidity meter 60 to move into the cleaning chamber 71 of the cleaning tank 70.
