[0038] Please refer to Figures 1-5The embodiment provides a dosing equipment based on wastewater treatment, which comprises a mixing bin 10, a mixing and stirring device 20 and a discharging device 30. The mixing bin 10 is internally provided with a mixing cavity 11. A solid feeding port 12 is formed in the mixing bin 10 and in communication with the mixing cavity 11. A liquid feeding port 13 is also formed in the mixing bin 10 and in communication with the mixing cavity 11. The stirring end of the mixing and stirring device 20 is arranged in the mixing cavity 11 and used for stirring materials in the mixing cavity 11. The discharging device 30 is connected with the mixing bin 10 and used for discharging mixed liquid in the mixing cavity 11.
[0039] In the embodiment, the mixing bin 10 is internally provided with the mixing cavity 11. The solid feeding port 12 and the liquid feeding port 13 are formed in the upper portion of the mixing bin 10 and in communication with the mixing cavity 11. Solid and liquid raw materials can be simultaneously fed into the mixing cavity 11 for mixing treatment.
[0040] The stirring end of the mixing and stirring device 20 is arranged in the mixing cavity 11 and used for continuously stirring materials in the mixing cavity 11, so that the sufficient contact between the solid and the liquid is promoted, the dissolution and reaction processes are accelerated, and the quality and composition of the finally output mixed liquid are stable.

The device can adopt multiple discharging modes such as pumping and self-flowing, and a suitable discharging mode can be selected according to different actual application scenes. The mixed liquid after discharging can be directly used for subsequent wastewater treatment processes.
[0042] The dosing equipment based on wastewater treatment provided by the embodiment can effectively complete the key functions of solid-liquid mixing, stirring and discharging through the coordination between various components. Moreover, the equipment in the scheme has a high degree of automation, which not only improves the operation convenience of the equipment, but also ensures the controllability and stability of the mixing process. In addition, the core components such as the mixing bin 10 and the mixing and stirring device 20 are made of high-quality corrosion-resistant materials, so that the equipment can be stably operated for a long time. The equipment is provided with perfect protection and safety devices, which can effectively prevent personnel injuries and environmental pollution accidents caused by improper operation or equipment failure, so that the dosing equipment has good reliability in actual application.
[0043] Please refer to Figures 1-5In some embodiments, the mixing and stirring device 20 comprises a paddle 21 placed in the mixing chamber 11 and a power source 22 with an output end penetrating the upper wall of the mixing bin 10, and the paddle 21 is sleeved on the output end of the power source 22, and the power source 22 is used to drive the paddle 21 to rotate to stir the materials.
[0044] In this embodiment, the paddle 21 is placed in the mixing chamber 11, which can effectively contact with the solid and liquid raw materials in the chamber, and promote the mixing process. Further, the design of the paddle 21 can be optimized according to the properties of the materials and the specific application requirements, for example, selecting different shapes and sizes of the paddle 21 to improve the stirring efficiency and mixing uniformity. The rotation of the paddle 21 not only enables the materials to flow in the chamber, but also accelerates the dissolution and reaction of solid particles through shearing and pushing action.
[0045] The output end of the power source 22 penetrates the upper wall of the mixing bin 10, effectively transmitting power to the paddle 21, ensuring that the stirring device can operate efficiently in the closed mixing bin 10, while avoiding the interference of the external environment on the mixing process. The power source 22 can be an electric motor, a pneumatic device or a hydraulic system, the specific choice depends on the requirements and economic considerations of the application scenario. The power of the power source 22 can be adjusted, so that the user can flexibly adjust the speed of the paddle 21 according to different material properties and mixing requirements, to achieve the best stirring effect.
[0046] Through the combination of the paddle 21 and the power source 22, the mixing and stirring device 20 can realize the rapid mixing of solid and liquid reagents in a short time, thereby improving the efficiency of reagent addition and the overall performance of wastewater treatment. This rapid and uniform mixing process not only significantly improves the reaction rate of the reagent, but also effectively reduces the use of reagents, reduces the waste of chemicals, and reduces operating costs. The closed design of the mixing and stirring device 20 effectively avoids material leakage and environmental pollution, improving the safety of operation. In summary, the mixing and stirring device 20 of this embodiment can efficiently realize the reagent addition process in wastewater treatment, improve the mixing efficiency and reaction rate, ensure uniform mixing, and has good safety, realizing efficient, energy-saving and environmentally friendly wastewater treatment.
[0047] Please refer to Figures 1-5 In some embodiments, a reagent addition device based on wastewater treatment further comprises a feed pipe 41 and an inlet valve 42; the feed pipe 41 is in communication with the liquid feed inlet 13, and the inlet valve 42 is placed on the feed pipe 41, and the inlet valve 42 is used to control the amount of liquid entering.
[0048] In this embodiment, the material and structure of the feed pipe 41 can be selected according to different application scenarios, such as using corrosion-resistant pipe material, or designing a detachable quick connector structure to meet the needs of convenient cleaning and maintenance.
[0049] The inlet valve 42 is installed on the feed pipe 41 to control the amount of liquid entering. By using a valve structure, the feed flow can be accurately adjusted to ensure that the amount of liquid raw material matches the ratio of solid raw material, avoiding uneven mixing due to imbalance in the ratio. The inlet valve 42 can be in the form of an electromagnetic valve, a pneumatic valve, or a manual valve, etc., and can be selected according to the actual application. At the same time, the inlet valve 42 also has an on-off control function, which can quickly cut off the feed when receiving instructions from the upper control system to deal with emergency situations.
[0050] Further, in order to better control and monitor the entire dosing process, the device can also be equipped with flow meters, pressure sensors and other auxiliary equipment. The flow meter is used to detect the liquid flow in the feed pipe 41 in real time, providing a basis for accurate control of the inlet valve 42. The pressure sensor is installed inside the mixing chamber 11 and can monitor the pressure changes during the mixing process to provide a reference for judging the mixing state. The data from these sensors can be fed back to the upper control system to achieve intelligent management of the entire dosing process.
[0051] By integrating the feed pipe 41 and the inlet valve 42, the amount of liquid raw material can be controlled to ensure a reasonable solid-liquid ratio, avoiding uneven mixing or incomplete reaction due to an imbalance in the ratio. This not only improves the quality of the final mixed liquid, but also significantly improves the efficiency of the entire dosing process. The inlet valve 42 can effectively deal with unexpected situations such as power failure or equipment failure, quickly cutting off the feed to avoid mixed liquid leakage and environmental pollution accidents, significantly improving the efficiency and safety of wastewater treatment.
[0052] Please refer to Figures 1-5 In some embodiments, the solid feed inlet 12 is placed on the top of the mixing bin 10.
[0053] In this embodiment, the solid feed inlet 12 is placed on the top of the mixing bin 10, which helps to achieve convenient feeding and uniform dispersion of solid medicaments. Through the top feed inlet, the operator can easily pour the solid medicaments directly into the mixing bin 10, avoiding interference and contamination of the equipment, and improving the convenience and safety of the dosing process. In addition, the design of the top feed inlet can also effectively utilize gravity, allowing the solid medicaments to naturally fall when entering the mixing chamber 11, ensuring rapid dispersion and mixing of the medicaments, thereby improving the mixing effect and overall efficiency of wastewater treatment. At the same time, the top position is also convenient for observation and maintenance, reducing the risk of operation that may occur during feeding.
[0054] Please refer toFigures 1-5 In some embodiments, the liquid feed port 13 is placed on the top of the mixing bin 10.
[0055] In this embodiment, the liquid feed port 13 is also arranged on the top of the mixing bin 10, which can make full use of gravity to make the liquid raw materials flow into the mixing chamber 11 naturally. Through top feeding, the liquid can be quickly and uniformly dispersed in the mixture, creating good conditions for subsequent stirring and reaction. At the same time, the position of the top feed port is also convenient for the operator to observe and adjust, improving the controllability of the dosing process. In addition, this design is also conducive to avoiding potential safety hazards such as leakage and pollution caused by the liquid feed port 13 being too low.
[0056] The top arrangement of the liquid feed port 13, combined with the design of the solid feed port 12, further optimizes the structure and process flow of the entire dosing equipment. Through gravity-driven and natural dispersion, liquid and solid raw materials can be quickly and uniformly mixed, improving the overall dosing efficiency. By adopting the scheme in this embodiment, not only the operation convenience of the equipment is enhanced, but also the safety and reliability of the dosing process are ensured.
[0057] Please refer to Figures 1-5 In some embodiments, the discharge device 30 includes a discharge pipe 31, an outlet valve 32, and a metering pump 33. The discharge pipe 31 is connected to the bottom of the mixing bin 10, and the discharge pipe 31 is in communication with the mixing chamber 11. The outlet valve 32 and the metering pump 33 are sequentially arranged on the discharge pipe 31 along the flow direction of the mixed liquid.
[0058] In this embodiment, the design of the discharge device 30 includes a discharge pipe 31, an outlet valve 32, and a metering pump 33, aiming to achieve efficient extraction and accurate metering of the mixed liquid. One end of the discharge pipe 31 is connected to the bottom of the mixing bin 10 and is in communication with the mixing chamber 11, so that the mixed liquid can flow out smoothly. The design of the discharge pipe 31 takes into account the fluid dynamics, ensuring that there is no blockage or poor flow during extraction, maximizing the uniformity of the mixed liquid, and avoiding uneven mixing or waste of reagents due to poor flow.
[0059] The outlet valve 32 is arranged on the discharge pipe 31 and is mainly used to control the outflow of the mixed liquid. The valve can be electric, pneumatic or manual, selected according to the degree of automation required. By adjusting the opening degree of the outlet valve 32, the operator can flexibly control the flow of the mixed liquid, ensuring accurate dosing under different process conditions. In addition, the metering pump 33 is also arranged on the discharge pipe 31 along the flow direction of the mixed liquid. The role of the metering pump 33 is to accurately meter the flow of the mixed liquid, and the operator can set the flow parameters according to the actual needs to meet the requirements of different wastewater treatment processes.
[0060] The use of metering pump 33 enables dynamic adjustment of the mixed liquid flow, facilitating real-time monitoring and feedback during the treatment process, ensuring that the entire dosing and mixing process is carried out within the set parameter range, avoiding subsequent treatment difficulties caused by inaccurate flow, thereby improving the efficiency and quality of wastewater treatment.
[0061] The discharge device 30 in this embodiment reduces the risk of liquid leakage and environmental pollution through reasonable flow direction and valve control, not only improving the discharge efficiency of the mixed liquid, but also ensuring the safety and reliability of the discharge process.
[0062] Please refer to Figures 1-5 In some embodiments, the discharge device 30 further comprises a Y-type filter 34, which is placed on the discharge pipe 31 and between the outlet valve 32 and the metering pump 33.
[0063] In this embodiment, the discharge device 30 further includes a Y-type filter 34 based on the aforementioned discharge pipe 31, outlet valve 32 and metering pump 33. The Y-type filter 34 functions to filter the mixed liquid flowing out of the mixing chamber 11, removing any impurities or particulate matter that may be present. This filtering device adopts a Y-type structure, with fluid being directed into two separate flow channels upon entering the filter, thereby creating a larger filtering area. The Y-type filter 34 is internally filled with a filter screen or cartridge, which can effectively trap solid impurities in the mixed liquid, ensuring that subsequent metering and conveying processes are not affected, improving the stability of the dosing process and significantly reducing the risk of equipment failure.
[0064] Preferably, the Y-type filter 34 has a detachable structure to facilitate regular opening of the filter for cleaning or replacement of the filter screen, ensuring long-term stable operation. Further, the Y-type filter 34 can be equipped with a differential pressure monitoring device to detect the degree of filter blockage in real time, providing timely maintenance recommendations.
[0065] Integrating the Y-type filter 34 into the discharge device 30 can effectively prevent equipment failure and performance degradation caused by impurities blocking. The filtered mixed liquid can be more safely and stably conveyed to subsequent wastewater treatment processes, improving the reliability of the entire dosing system. At the same time, by removing impurities, the utilization rate of the reagent can be improved, reducing secondary pollution caused by excessive reagent.

[0067] In this embodiment, the design of the reaction tank 50 aims to provide a sufficient reaction space for the mixed solution, so that the medicament can react with the pollutants in the wastewater here. The internal structure of the reaction tank 50 can be designed as multi-stage or single-stage as needed, and equipped with appropriate stirring devices to enhance the flowability and reaction uniformity of the mixed solution.
[0068] The capacity and shape of the reaction tank 50 can be customized according to the specific wastewater treatment requirements, so that it can adapt to different flow rates and reaction times. Further, temperature and pH sensors can be provided in the reaction tank 50 to monitor the reaction conditions in real time and automatically adjust the dosage of the medicament, ensuring that the reaction process is carried out in the best state. To improve the treatment efficiency, the reaction tank 50 can also be equipped with a gas diffusion device to promote gas exchange in the mixed solution, further enhancing the reaction effect. Through the connection design of the reaction tank 50 and the discharge pipe 31, the reaction tank 50 not only can receive the mixed solution, but also can optimize the reaction conditions, reducing the risk of material loss and secondary pollution, and improving the overall efficiency and environmental benefits of wastewater treatment.
