[0009] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0010] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0011] Please see Figure 1-2 The following technical challenges are commonly found in existing wastewater treatment chemical dosing technologies: Defects of the filtration system: Traditional filtration modules mostly adopt a fixed filter element design, which is difficult to disassemble and assemble and cannot monitor the clogging status in real time, resulting in a decrease in filtration efficiency, easy to cause secondary pollution, and affecting the mixing effect of the medicine and water and the efficacy of the medicine.

[0012] Inadequate powder handling: The powder mixing structure often results in insufficient dissolution due to clumping. The lack of a dynamic crushing mechanism affects the mixing efficiency of powder and water, leading to inaccurate dosage and even pipe blockage.

[0013] Weak safety redundancy: In emergency situations (such as abnormal drug concentration or equipment failure), there is a lack of rapid response mechanism. Traditional release tubes require manual operation, have a slow response speed, and lack linkage control logic, which can easily expand the scope of the accident.

[0014] Water hammer effect interference: The shock wave (water hammer effect) generated by sudden changes in water flow in the pipeline can easily cause equipment vibration and pipeline rupture. Existing technologies mostly rely on empirical buffer design and lack real-time pressure monitoring and automatic adjustment functions.

[0015] Lack of automated control: The powder replenishment and stirring process relies on manual operation, and the grinding speed cannot be dynamically adjusted according to the powder consumption, resulting in a mismatch between the dosing speed and the processing requirements, which affects the processing efficiency and stability.

[0016] This invention addresses the aforementioned problems by integrating filtration, mixing, conveying, and safety redundancy systems through modular design, achieving efficient filtration, precise dosing, and intelligent safety control. Specific improvements include: The integrated filtration module uses a quick-release composite filtration unit (activated carbon + ceramic membrane), along with a transparent observation window to monitor the clogging status in real time, ensuring stable water quality. The powder stirring structure incorporates a built-in pulverizing power rotor and an internal pulverizing roller to dynamically pulverize agglomerated powder and improve dissolution efficiency. Multiple safety redundancy mechanisms (electromagnetic shut-off valve linked to PLC control, emergency recovery valve, pulse damper) enable rapid discharge and system protection in abnormal situations; The pulse damper adopts an airbag structure, which, together with a dual-pointer pressure gauge, monitors the pressure threshold in real time and triggers an audible and visual alarm to mitigate the water hammer effect. The weighing sensor is linked to the pulverizing power rotor to automatically replenish the powder and adjust the speed, realizing closed-loop control of the dosing process and ensuring constant fusion efficiency.

[0017] Through the above innovations, this invention solves the technical bottlenecks of traditional wastewater treatment dosing systems in terms of filtration, stirring, safety control, and automation, improves treatment efficiency and system stability, reduces the risk of secondary pollution, and ensures the safe and efficient operation of the wastewater treatment process. Therefore, this application protects a wastewater treatment dosing mechanism. After the inlet pipe is connected to the inlet valve 15, when the inlet valve 15 is opened, the water flows through the pipe to the second connecting tee pipe 13. At this time, the reserved second release pipe 14 interface can be connected to other pipes for equipment pre-rinsing or chemical addition. After the water flows through the second connecting tee pipe 13, it continues to flow to the integrated filter module 12. The filter material built into the integrated filter module 12 supports quick disassembly and assembly. When the second release pipe 14 is not connected to other pipes, the filter material of the integrated filter module 12 will clean and filter the water source to ensure water purity and avoid secondary pollution during wastewater treatment dosing, which would affect the efficacy of the chemicals. Then, the chemical powder is injected into the chemical powder carrying shell 18 container through the dosing port 19. Subsequently, the crushing power rotor 17 in the power protection shell 16 is started. Its operation will drive the crushing roller 20 inside the shell to rotate in the chemical powder carrying shell 18, thoroughly crushing the incoming agglomerated chemical powder and promoting the full mixing of chemical powder and water. The mixed solution is then discharged through the chemical discharge electromagnetic valve. Valve 3 releases intermittently, and the solution is then pressurized by the metering pump body 2 on the metering pump base 1, and forced towards the back pressure valve 7 (safety valve). The solution is then transported through the No. 1 connecting tee pipe 8, and finally flows into the next stage of wastewater treatment from the terminal valve 10. This system also incorporates multiple safety redundancy mechanisms: the first release pipe 9 valve can quickly release or sample the solution in an emergency; the pulse damper 5 device can mitigate the water hammer effect in the pipeline, making the water flow to the terminal valve 10 more stable; if the first release pipe 9 cannot completely handle the emergency, the emergency recovery valve 4 valve can be opened, releasing the solution and recovering some of the liquid; the damper status gauge 6 device monitors the operating status of the pulse damper 5, further improving system stability. In addition, the back pressure valve 7 (safety valve) serves as a second layer of protection, providing additional safety assurance for the overall equipment operation. The entire process achieves three core functions—high-efficiency filtration, precise dosing, and safe release—through modular design, ensuring both treatment effectiveness and operational safety through multiple redundancy designs, ensuring a stable and reliable wastewater treatment process.

[0018] In summary, this wastewater treatment dosing mechanism achieves fully automated control through modular design. The operating process and principle are as follows: After the inlet pipe is connected to the inlet valve 15, when the valve is opened, water flows through the second connecting tee pipe 13. At this time, the second release pipe 14 can connect to the pre-rinsing or dosing pipeline. The water flows into the integrated filter module 12 (built-in activated carbon + ceramic membrane composite filter unit). The filter media can be replaced through a snap-fit ​​design. A transparent observation window monitors the blockage status in real time. When the second release pipe 14 is not connected, the water source is automatically filtered to avoid secondary pollution. Powder is injected into the powder carrier housing 18 through the dosing port 19. The built-in pulverizing rotor 17 drives the pulverizing roller 20 inside the housing to rotate and pulverize the agglomerated powder. The bottom weighing sensor is linked to the PLC controller. When the powder weight is below the threshold, the solenoid valve of the dosing port 19 is automatically opened to replenish the powder and the rotation speed is adjusted to match the dosing speed. After being metered by calibration column 11, the mixed liquid is pressurized by metering pump 2. The pulse damper 5 (airbag structure + dual-pointer pressure gauge) mitigates water hammer effects. After the back pressure valve 7 stabilizes the pressure, the liquid enters the first connecting tee pipe 8. Terminal valve 10 controls the main flow direction. Both the first release pipe 9 and the second release pipe 14 are equipped with electromagnetic shut-off valves. Through PLC linkage with the metering pump, abnormal liquid discharge and sampling are achieved. If the first release pipe 9 fails, emergency recovery valve 4 activates the liquid recovery function. The system integrates multiple safety redundancies: damper status gauge 6 monitors pressure in real time and triggers audible and visual alarms; back pressure valve 7 provides secondary safety protection; and the entire process is controlled by a PLC controller to achieve closed-loop control of parameters such as flow rate, pressure, and powder dosage, ensuring the three core functions of efficient filtration, precise dosing, and safe release. This guarantees stable and reliable operation of the wastewater treatment system. Simultaneously, the automated design reduces the need for manual intervention, improving system response speed and treatment accuracy.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
