Description

Technical Field

[0001] The present invention relates to the technical field of tap water disinfection equipment, and in particular to a real-time monitoring and self-adjusting intelligent dosing system for a waterworks, and also to a real-time monitoring and self-adjusting intelligent dosing method for a waterworks. Background Art

[0002] At present, tap water dosing systems rarely consider important factors such as flow rate changes and water quality changes. Most of them dosing chemicals based on fixed ratios or pre-set flow values. Faced with sudden increases or decreases in water flow, it is often impossible to quickly adjust the chemical dosing rate, resulting in excessive or insufficient chemical dosing. Excessive dosing not only wastes resources and increases treatment costs, but may also produce excess chemicals, causing unnecessary burdens on the environment. Conversely, insufficient chemical dosing cannot effectively purify water quality, affecting water supply safety and public health.

[0003] The currently disclosed Chinese patent CN220351829U discloses an intelligent tap water dosing and disinfection device, which includes a detector group for detecting chemical substances in a water treatment pool, and a control center for controlling the device. The detector group is connected to the control center to transmit detection data, and also includes an intelligent dosing device and a liquid level meter for measuring and detecting the water level of the water treatment pool. The dosing device is bidirectionally connected to the water treatment pool. The dosing device includes a high-level drug dispensing tank, in which a stirring device and a drug storage barrel are arranged. An electric control valve is installed on the outlet of the drug storage barrel, and a second liquid level meter is arranged in the barrel. The electric control valve and the second liquid level meter are connected to the control center. The high-position medicine dispensing tank is connected to the water treatment tank through a medicine discharge pipe, a water inlet pipe and a water plant treatment tank. A metering pump is connected between the water inlet pipe and the water plant treatment tank. A control valve is installed on the medicine discharge pipe to fill water into the high-position medicine dispensing tank and add medicine to the water plant treatment tank for disinfection. The stirring device is a stirring structure driven by a motor. The detector group includes an online aluminum ion analyzer for online monitoring of aluminum ion data in water, a sodium hypochlorite effective chlorine online analyzer for real-time monitoring of changes in sodium hypochlorite concentration, an ammonium sulfate effective content analyzer for real-time monitoring of changes in ammonium sulfate concentration, and an ammonia nitrogen detector for real-time monitoring of free ammonia and total ammonia nitrogen.

[0004] According to the above patent, the above patent calculates the volume of water in the water treatment pool of the water plant by detecting the water level through a liquid level meter, and then calculates the amount of disinfectant that needs to be put in, and then accurately puts the disinfectant into the high-position dispensing tank through a second liquid level meter and an electric control valve, and fills the high-position dispensing tank with water through a water inlet pipe, and the stirring device stirs and dilutes it, and finally discharges it into the water treatment pool of the water plant through a drug discharge pipe for disinfection. However, the disinfectant cannot be evenly dispersed when it is put in at one point. If it cannot be quickly and evenly mixed with the water body, the concentration of the disinfectant in the local area may be too low, which is not enough to effectively kill pathogens, affecting the disinfection effect. On the contrary, if the concentration of disinfectant in some areas is too high, it may not be fully neutralized before discharge, resulting in excessive disinfection by-products, affecting water quality safety. Therefore, there is a need for an intelligent dosing system for water plants that controls the flow rate of the agent, ensures that the preset amount of medicine is added slowly and accurately, and ensures that the agent is quickly and evenly dispersed in the water while dosing the medicine. Summary of the invention

[0005] In view of the problems existing in the existing technology, a real-time monitoring and self-adjusting intelligent dosing system for water plants is provided. After a preset amount of medicine is injected into the medicine storage chamber, the caliber control mechanism is started to automatically and uniformly open all the dosing ports to ensure that the amount of medicine released at each point is consistent at the same time. Combined with the rotation of the stirring shaft, under the action of the rotating linkage component, the dosing bin is driven to rotate at the same time, ensuring that the medicine can be evenly distributed throughout the entire tank body.

[0006] In order to solve the problems of the prior art, the present invention provides a real-time monitoring and self-adjusting intelligent dosing method for a water plant, comprising a tank body, a water body input unit, a drug input unit, an automatic dosing unit, a stirring and mixing unit and a water quality monitoring unit, wherein the stirring and mixing unit has a stirring shaft arranged in the tank body and a stirring blade arranged on the stirring shaft, the automatic dosing unit is arranged in the upper half of the tank body, the automatic dosing unit comprises a dosing chamber body with a plurality of dosing ports, and a caliber control mechanism capable of controlling the opening and closing states of all dosing ports, and the upper half of the tank body is provided with a plurality of dosing ports. The lower half is divided into a medicine storage chamber and a mixing chamber by a medicine dosing chamber body. When a preset amount of medicine is input into the medicine storage chamber, all the medicine dosing ports are in a closed state under the action of the caliber control mechanism. After the preset amount of medicine is input into the medicine storage chamber, all the medicine dosing ports are in an open state under the action of the caliber control mechanism. The medicine dosing chamber body can rotate around the rotation axis of the stirring shaft in the tank body. A rotating linkage component is provided between the stirring shaft and the medicine dosing chamber body. When the stirring shaft rotates, the rotating linkage component acts on the medicine dosing chamber body to make the medicine dosing chamber body rotate synchronously.

[0007] Preferably, the medication storage body is a cylindrical structure, and a buffer funnel is fixedly provided in the tank body and located above the medication storage body for buffering the impact force generated during the medicine input process. The buffer funnel is provided with a liquid level sensor for monitoring the liquid level of the medicine in the medication storage body.

[0008] Preferably, an annular inner liner and an annular outer liner for confining the medication bin body therein are fixedly provided in the tank body, the caliber control mechanism includes a plunger body arranged in each medication port, all the plunger bodies are arranged between the annular inner liner and the annular outer liner, the medication bin body can move relative to the plunger body along the axial direction of the stirring shaft, the caliber control mechanism also includes a lifting component for driving the medication bin body to approach or move away from the plunger body, when the medication bin body moves upward, the opening of each medication port tends to gradually decrease, conversely, when the medication bin body moves downward, the opening of each medication port tends to gradually increase.

[0009] Preferably, the rotary linkage assembly includes a force-applying portion fixedly arranged on the stirring shaft, and a force-receiving portion fixedly arranged at the bottom of the medication bin body. When the medication bin body moves upward so that the medication port is closed by the plunger body, the force-receiving portion is located outside the rotation range of the force-applying portion. At this time, the stirring shaft drives the stirring blade to rotate at a high speed. Conversely, when the medication bin body moves downward so that the medication port is away from the plunger body and is opened, the force-receiving portion is located within the rotation range of the force-applying portion. At this time, the stirring shaft drives the medication bin body to rotate at a low speed.

[0010] Preferably, the force-applying part and the force-receiving part are both plate-like structures, and the upper end of the force-applying part and the lower end of the force-receiving part both have pointed ends. When the medication chamber moves downward so that the force-receiving part is pressed on the force-applying part, the pointed ends between the force-receiving part and the force-applying part interact, forcing the two to be in an interlaced state.

[0011] Preferably, a rotating frame body is coaxially and rotatably provided in the tank body for fixedly connecting all the plunger bodies, a bearing is provided between the rotating frame body and the annular outer liner, the outer edge of the medication bin body has a guide bar extending upward along its axial direction, and the outer edge of the rotating frame body is provided with a guide groove for the guide bar to slide and engage therein, when the medication bin body rotates, the rotating frame body is in a state of rotating together, so that each plunger body and the corresponding medication port remain in a coaxial state.

[0012] Preferably, the plunger body is specifically an inverted cone structure, and the drug injection port is provided with a sealing rubber sleeve that can fit with the plunger body.

[0013] Preferably, a distance sensor for sensing the opening size of the medication inlet is fixedly provided on the rotating frame, and a sensing module for detection by the distance sensor is fixedly provided on the medication chamber.

[0014] Preferably, the lifting assembly includes a pressure piece in contact with the bottom of the medication bin body, and a pressure-applying piece capable of controlling the pressure piece. When the pressure-applying piece applies upward pressure to the pressure piece, the medication bin body is lifted upward, and when the pressure-applying piece releases the pressure, the medication bin body automatically falls down under its own gravity and the support of the medicine.

[0015] The present invention also provides a real-time monitoring and self-regulating intelligent drug dosing method for a water plant, comprising the following steps:

[0016] S1. According to the water quality analysis results, set the type and dosage of the agent;

[0017] S2. The medicine is accurately delivered into the medicine storage cavity through the medicine feeding pipe, and the caliber control mechanism keeps the medicine feeding port closed during this process;

[0018] S3. When the medicine storage chamber reaches the preset amount of medicine, the caliber control mechanism automatically opens the medicine feeding port to cause the medicine to flow into the mixing chamber;

[0019] S4. Start the stirring shaft to rotate, drive the dosing chamber to rotate synchronously, so that the medicine and the water are evenly mixed.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. After a preset amount of medicine is injected into the medicine storage cavity, the aperture control mechanism is activated to uniformly open all the medicine feeding ports to ensure that the amount of medicine released at each point is consistent at the same time. Combined with the rotation of the stirring shaft, under the action of the rotating linkage component, the medicine feeding bin is driven to rotate at the same time, ensuring that the medicine can be evenly distributed throughout the entire tank body, thereby ensuring that the medicine is quickly and evenly dispersed in the water, avoiding excessively high or low local concentrations, improving the utilization efficiency and treatment effect of the medicine, and automatically adjusting the amount of medicine input through the self-regulating mechanism under the real-time monitoring of the mixed water by the water quality monitoring unit, thereby achieving highly automated and intelligent management of the entire process and ensuring the stability of the final water quality.

[0022] 2. The present invention uses intelligent control of the dosing system. During the drug delivery stage, the force-bearing part automatically enters the rotation range of the force-applying part, controls the stirring shaft to rotate at a low speed, thereby driving the drug delivery bin to rotate smoothly, ensuring stable multi-point drug delivery and allowing the drug to be evenly dispersed in the water body. When the drug delivery stage is stopped, the force-bearing part leaves the rotation range of the force-applying part and controls the stirring shaft to rotate at a high speed, so that the dispersed drug and the water body are further fully mixed, thereby improving the mixing efficiency, accelerating the reaction process, and ensuring efficient dissolution and uniform distribution of the drug.

[0023] 3. The present invention utilizes the coaxial rotation design of the rotating frame and the drug delivery chamber, so that each plunger body can maintain strict alignment with the corresponding drug delivery port, ensuring the accuracy and consistency of drug delivery. Even in dynamic rotation, the precise adjustment of the drug delivery port opening can be maintained, thereby improving the accuracy of drug addition and avoiding uneven drug distribution.

[0024] 4. By setting up a water quality monitoring unit in the system to continuously monitor the mixed water quality, the water quality changes can be fed back in real time. By setting the lifting component in the caliber control mechanism that drives the dosing bin body to move closer to or away from the plunger, the size of the opening between the dosing port and the plunger body can be adjusted to dynamically adjust the amount of medicine added.

DETAILED DESCRIPTION

[0036] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] See also Figure 1-Figure 5 As shown, a real-time monitoring and self-regulating intelligent dosing system for a water plant comprises a tank body 1, a water body input unit 2, a drug input unit 3, an automatic dosing unit 4, a stirring and mixing unit 5 and a water quality monitoring unit 6, wherein the stirring and mixing unit 5 comprises a stirring shaft 51 arranged in the tank body 1, and a stirring blade 52 arranged on the stirring shaft 51, the automatic dosing unit 4 is arranged in the upper half of the tank body 1, the automatic dosing unit 4 comprises a dosing chamber body 41 having a plurality of dosing ports 411, and a caliber regulating mechanism 42 capable of regulating the opening and closing states of all the dosing ports 411, the upper half and the lower half of the tank body 1 are divided by the dosing chamber body 41 It is divided into a medicine storage chamber 11 and a mixing chamber 12. When a preset amount of medicine is input into the medicine storage chamber 11, all the medicine injection ports 411 are in a closed state under the action of the caliber control mechanism 42. After the preset amount of medicine is input into the medicine storage chamber 11, all the medicine injection ports 411 are in an open state under the action of the caliber control mechanism 42. The medicine injection chamber 41 can rotate around the rotation axis of the stirring shaft 51 in the tank body 1. A rotating linkage component 43 is provided between the stirring shaft 51 and the medicine injection chamber 41. When the stirring shaft 51 rotates, the rotating linkage component 43 acts on the medicine injection chamber 41, so that the medicine injection chamber 41 rotates synchronously.

[0038] The water input unit 2 has a water inlet pipe 21 connected to the tank body 1, and a water outlet 22 is opened at the bottom of the tank body 1. The drug input unit 3 has a drug administration pipe 31 connected to the tank body 1. The water inlet pipe 21 and the drug administration pipe 31 are both arranged on the top of the tank body 1. The water quality monitoring unit 6 has a mixed water quality detector 61 arranged at the bottom of the tank body 1, and a raw water quality detector 62 arranged on the water inlet pipe 21. A water flow meter 211 and a drug liquid flow meter 311 are respectively provided at the pipe orifices of the water inlet pipe 21 and the drug administration pipe 31.

[0039] The entire dosing process starts with the introduction of raw water, which enters the tank body 1 through the water inlet pipe 21 of the water body input unit 2. Prior to this, the raw water quality detector 62 has preliminarily tested the water source to ensure that the water quality meets the treatment standard, and the amount of water injected into the tank body 1 is accurately measured through the water body flow meter 211, realizing intelligent control of the water inlet process. After the preset amount of raw water is injected into the tank body 1, the medicine is input into the dosing chamber 41 through the medicine input unit 3. According to the preset medicine formula and the current water volume and water quality data, the required amount of medicine is calculated by an intelligent algorithm. Subsequently, the medicine is accurately measured by the liquid flow meter 311 of the dosing pipeline 31 and injected into the medicine storage chamber 11. The whole process is automatically completed by the dosing system without manual intervention. At this stage, all dosing ports 411 are kept closed under the control of the caliber control mechanism 42. Ensure that the medicine is completely stored in the medicine storage chamber 11 to prevent the medicine from flowing into the water body through some dosing ports 411, resulting in uneven dispersion of the medicine. When the medicine storage chamber 11 reaches the preset medicine dosage, the caliber control mechanism 42 starts, and all the medicine feeding ports 411 are opened at one time, so that the medicine dosage at each medicine feeding port 411 remains consistent. At the same time, the stirring shaft 51 of the stirring and mixing unit 5 starts to rotate, driving the stirring blades 52 installed thereon to stir the water in the tank body 1. The stirring shaft 51 and the medicine feeding bin body 41 are precisely matched through the rotating linkage assembly 43, so that the medicine feeding bin body 41 rotates with the stirring shaft 51. It ensures that the medicine can be evenly distributed throughout the tank body 1, avoiding excessive or low local concentrations, and improving the utilization efficiency and treatment effect of the medicine. As the stirring continues, the medicine in the medicine storage chamber 11 is evenly released into the mixing chamber 12 through the opened medicine feeding port 411, and the medicine and the water are dispersed and dissolved under stirring to form a treatment liquid in which the medicine and the water are fully mixed. During this process, the water quality monitoring unit 6 continuously monitors the mixed water quality and provides real-time feedback on water quality changes through the mixed water quality detector 61, thereby achieving highly automated and intelligent management of the entire dosing process and providing a basis for dynamic adjustment of the dosage of the drug.

[0040] See also Figure 2-Figure 5As shown, the medication chamber 41 is a cylindrical structure, and a buffer funnel 111 is fixedly provided in the tank body 1 above the medication chamber 41 for buffering the impact force generated during the medicine input process, and a liquid level sensor 112 is provided on the buffer funnel 111 for monitoring the liquid level of the medicine in the medication chamber 41.

[0041] According to the processing requirements, the staff will send the specified type and amount of medicine into the medicine input unit 3, and the medicine will be transported to the buffer funnel 111 through the medicine feeding pipe 31, absorbing the kinetic energy of the medicine falling, so that the medicine can gently transition to the medicine storage chamber 11, avoiding the damage of the internal structure that may be caused by direct impact. This process is controlled by intelligent control to ensure the smooth delivery of the medicine. As the medicine reaches the preset amount, the caliber control mechanism 42 opens all the medicine feeding ports 411. After the medicine reaches the preset amount and all the medicine feeding ports 411 are opened, the stirring and mixing unit 5 is immediately started, and the stirring shaft 51 drives the stirring blade 52 and the rotating linkage medicine feeding warehouse 41 to work together. The medicine is evenly dispersed in the tank body 1 and fully mixed with the water body. The liquid level of the medicine in the medicine feeding warehouse 41 is monitored in real time by the liquid level sensor 112, so as to effectively control the opening of the caliber control mechanism 42 to the medicine feeding port 411, and control the medicine feeding speed in a self-adjusting manner to ensure that the medicine can be fully and evenly put into the water body.

[0042] See also Figure 2-Figure 7 As shown, an annular liner 412 and an annular outer liner 413 for limiting the drug administration bin body 41 therein are fixedly provided in the tank body 1, and the caliber control mechanism 42 includes a plunger body 421 arranged in each drug administration port 411, and all plunger bodies 421 are arranged between the annular liner 412 and the annular outer liner 413. The drug administration bin body 41 can move relative to the plunger body 421 along the axial direction of the stirring shaft 51, and the caliber control mechanism 42 also includes a lifting component 422 for driving the drug administration bin body 41 to approach or move away from the plunger body 421. When the drug administration bin body 41 moves upward, the opening of each drug administration port 411 tends to gradually decrease. Conversely, when the drug administration bin body 41 moves downward, the opening of each drug administration port 411 tends to gradually increase.

[0043] The annular liner 412 and the stirring shaft 51 form a water injection cavity for the water supply body to be injected into the tank body 1. The water inlet pipe 21 is connected to the annular liner 412 and is provided with a connecting pipe 4121, so that the water body is directly injected into the tank body 1 without passing through the automatic dosing unit 4, preventing impurities in the water body from being retained therein and affecting the subsequent dosing steps. The annular liner 412 and the annular outer liner 413 also form a stable frame to limit the range of motion of the dosing warehouse body 41. When the position of the dosing warehouse body 41 changes, the relative position of the plunger body 421 and the dosing port 411 also changes accordingly, thereby realizing the fine adjustment of the opening of the dosing port 411, so that the release rate and total amount of the medicine can be accurately controlled. In order to drive the dosing warehouse body 41 to move up and down, the dosing warehouse body 41 is pushed up and down along the axis by the lifting assembly 422, thereby adjusting the size of the dosing port 411, so as to control the dosing speed, ensure that the medicine is evenly dispersed in the water body, and avoid the situation where there is too much or too little medicine in the local water body.

[0044] See also Figure 2-Figure 7 and Fig. 9 As shown, the rotating linkage assembly 43 includes a force-applying portion 431 fixedly arranged on the stirring shaft 51, and a force-bearing portion 432 fixedly arranged at the bottom of the medication bin body 41. When the medication bin body 41 moves upward so that the medication port 411 is closed by the plunger body 421, the force-bearing portion 432 is located outside the rotation range of the force-applying portion 431. At this time, the stirring shaft 51 drives the stirring blade 52 to rotate at a high speed. Conversely, when the medication bin body 41 moves downward so that the medication port 411 is away from the plunger body 421 and is opened, the force-bearing portion 432 is located within the rotation range of the force-applying portion 431. At this time, the stirring shaft 51 drives the medication bin body 41 to rotate at a low speed.

[0045] When the dosing chamber body 41 moves upward, so that the dosing port 411 is tightly closed by the plunger body 421, the force-bearing portion 432 will move out of the rotation track of the force-applying portion 431. At this moment, the stirring shaft 51 and its attached stirring blades 52 can run at full speed without hindrance. The high-speed rotating stirring blades 52 can quickly and thoroughly mix the water body and the administered medicine, ensuring that the medicine in the treatment area is evenly distributed and accelerating the reaction process. On the contrary, when it is necessary to dosing, the dosing chamber body 41 moves downward, the dosing port 411 is opened, and the force-bearing portion 432 re-enters the rotation path of the force-applying portion 431. At this time, the rotation of the stirring shaft 51 is automatically switched to a low-speed mode due to the restraint of the force-bearing portion 432. The low-speed rotation not only ensures that the released medicine will not be unevenly dispersed due to rapid rotation, but also allows the medicine to be more smoothly integrated into the water body, promoting the stable dispersion and effective use of the medicine.

[0046] See also Figure 4-Figure 6 and Fig. 9As shown, the force-applying part 431 and the force-receiving part 432 are both plate-like structures, and the upper end of the force-applying part 431 and the lower end of the force-receiving part 432 both have pointed ends. When the medication chamber body 41 moves downward so that the force-receiving part 432 is pressed on the force-applying part 431, the pointed ends between the force-receiving part 432 and the force-applying part 431 interact, forcing the two to be in a staggered state.

[0047] As the medication bin body 41 moves downward according to the demand for medication delivery, the force-bearing part 432 gradually enters the rotation area of ​​the force-applying part 431. If the force-bearing part 432 presses on the force-applying part 431 during the downward movement, due to the presence of the tip, the force-bearing part 432 will not be supported on the force-applying part 431, but will continue to slide down along the tip to enter the rotation area of ​​the force-applying part 431. Subsequently, the power transmitted by the stirring shaft 51 through the force-applying part 431 is effectively and stably transmitted to the force-bearing part 432, thereby driving the medication bin body 41 to rotate.

[0048] See also Figure 2-Figure 8 As shown, a rotating frame body 423 for fixedly connecting all the plunger bodies 421 is coaxially and rotatably provided in the tank body 1, a bearing 424 is provided between the rotating frame body 423 and the annular outer liner 413, the outer edge of the medication bin body 41 has a guide bar 4231 extending upward along its axial direction, and the outer edge of the rotating frame body 423 is provided with a guide groove 4232 for the guide bar 4231 to slide and engage therein, when the medication bin body 41 rotates, the rotating frame body 423 is in a state of rotating together, so that each plunger body 421 and the corresponding medication port 411 remain in a coaxial state.

[0049] A rotating frame 423 coaxially arranged in the tank body 1 ensures that all plunger bodies 421 can rotate synchronously with the rotating frame 423 as an integral unit. When the dosing bin body 41 rotates together with the stirring shaft 51, the guide bar 4231 and the guide groove 4232 cooperate to drive the rotating frame 423 to rotate together. When adjusting the position of the dosing bin body 41, the control of the lifting assembly 422 prompts the dosing bin body 41 to move along its axis relative to the rotating frame 423, that is, the guide bar 4231 slides smoothly in the guide groove 4232, so that the dosing bin body 41 can also adjust its position while rotating. Even in a dynamic environment of continuous rotation, each plunger body 421 can be driven by the rotating frame 423 to maintain strict coaxial alignment with the corresponding dosing port 411, thereby ensuring the precise adjustment of the opening of the dosing port 411.

[0050] See also Figure 4 and Figure 7 As shown, the plunger body 421 is specifically an inverted cone structure, and the drug injection port 411 is provided with a sealing rubber sleeve 4211 that can fit with the plunger body 421 .

[0051] When the medicine feeding chamber body 41 moves upward so that the medicine feeding port 411 is connected with the inverted cone-shaped plunger body 421, the conical surface of the plunger body 421 gradually comes into close contact with the sealing rubber sleeve 4211 inside the medicine feeding port 411. As the plunger body 421 goes deeper, the contact area gradually increases, forming a reliable sealing barrier, effectively preventing the leakage of medicine during the process of stopping the medicine feeding, and ensuring that only the preset amount of medicine is fed. In addition, the cooperation between the inverted cone structure of the plunger body 421 and the sealing rubber sleeve 4211 can effectively control the amount of medicine fed, and improve the effect of uniform dispersion of the medicine.

[0052] See also Figure 4 and Figure 8 As shown, a distance sensor 425 for sensing the opening size of the medicine feeding port 411 is fixedly disposed on the rotating frame 423 , and a sensing module 4251 for the distance sensor 425 to detect is fixedly disposed on the medicine feeding chamber body 41 .

[0053] When the dosing chamber body 41 moves downward, the dosing port 411 gradually moves away from the plunger body 421. At this time, the distance sensor 425 also gradually moves away from the sensing module 4251. The distance sensor 425 monitors the distance between the sensing module 4251 in real time, thereby determining the opening size of the dosing port 411. The sensing module 4251 interacts with the distance sensor 425 as a measurement reference point to dynamically monitor the distance change between the two. During the dosing operation, the current opening size of the dosing port 411 is accurately calculated. According to the preset relationship between the dosing amount and the opening, the dosing speed is adjusted or the dosing is stopped in real time to achieve the expected amount of added medicine.

[0054] See also Figure 4 , Figure 5 and Fig.10 As shown, the lifting assembly 422 includes a pressure piece 4221 in contact with the bottom of the medication bin body 41, and a pressure piece 4222 capable of controlling the pressure piece 4221. When the pressure piece 4222 applies upward pressure to the pressure piece 4221, the medication bin body 41 is lifted upward, and when the pressure piece 4222 releases the pressure, the medication bin body 41 automatically falls under its own gravity and the support of the medicine.

[0055] The pressing member 4221 has a sphere 4223 and a rod 4224 integrally connected to the sphere 4223. The bottom of the medicine feeding chamber 41 is provided with an annular groove along its circumferential direction for the sphere 4223 to be embedded therein. The pressurizing member 4222 has a rod sleeve 4225 fixedly arranged on the annular outer liner 413 for the rod 4224 to be inserted therein from the upper end, and a pressure regulating tube 4226 connected to the lower end of the rod sleeve 4225. A buffer spring 4227 is fixedly sleeved on the rod sleeve 4225 for supporting the sphere 4223.

[0056] When controlling the medication chamber body 41 to move upward so that the medication port 411 is close to the plunger body 421, the pressure member 4222 is activated, and air pressure is applied to the rod sleeve 4225 through the pressure regulating tube 4226, thereby applying an upward thrust to the rod body 4224. The rod body 4224 moves upward under the pressure, driving the ball 4223 to move upward, and the contact surface with the ring groove transmits force to the bottom of the medication chamber body 41, so that the entire medication chamber body 41 rises steadily along the axial direction, thereby causing the opening of the medication port 411 to gradually decrease. When the pressure member 4222 stops pressurizing or actively reduces pressure, the pressure in the rod sleeve 4225 decreases, and the medication chamber body 41 automatically falls under its own gravity and the pressure of the medicine therein, thereby causing the ball 4223 to descend, causing the opening of the medication port 411 to gradually increase, effectively regulating the medication rate.

[0057] A real-time monitoring and self-regulating intelligent dosing method for a water plant is applied to a real-time monitoring and self-regulating intelligent dosing system for a water plant, comprising the following steps:

[0058] S1. According to the water quality analysis results, set the type and dosage of the agent;

[0059] S2, the medicine is accurately delivered into the medicine storage cavity 11 through the medicine delivery pipe 31, and during this process, the caliber control mechanism 42 keeps the medicine delivery port 411 closed;

[0060] S3, when the medicine storage chamber 11 reaches the preset amount of medicine, the caliber control mechanism 42 automatically opens the medicine injection port 411 to cause the medicine to flow into the mixing chamber 12;

[0061] S4, start the stirring shaft 51 to rotate, drive the medicine storage chamber 41 to rotate synchronously, so that the medicine and the water are evenly mixed.

[0062] The present invention injects a preset amount of medicine into the medicine storage chamber 11, and then starts the caliber control mechanism 42 to uniformly open all the medicine feeding ports 411, thereby ensuring that the amount of medicine released at each point is consistent at the same time. Combined with the rotation of the stirring shaft 51, under the action of the rotating linkage component 43, the medicine feeding bin 41 is driven to rotate at the same time, ensuring that the medicine can be evenly distributed throughout the entire tank body 1, thereby ensuring that the medicine is quickly and evenly dispersed in the water, avoiding excessively high or low local concentrations, and improving the utilization efficiency and treatment effect of the medicine. The entire process automatically adjusts the amount of medicine input according to the real-time monitoring data, and under the real-time monitoring of the mixed water by the water quality monitoring unit 6, the amount of medicine input can be adjusted in time through intelligent analysis to ensure the final water quality stability.

[0063] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
