Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an intelligent microbial slow-release device based on dynamic mixing. Background Technology

[0002] Traditional microbial application methods rely heavily on manual operation or fixed timers, which have significant limitations. Manual application is not only inefficient and costly, but also difficult to precisely control the dosage. Timers, on the other hand, cannot dynamically adjust the concentration and dosage of the microbial agent based on real-time water quality fluctuations (such as sudden increases in ammonia nitrogen concentration or sudden drops in dissolved oxygen), often resulting in excessive waste or insufficient application of the agent, leading to delayed treatment. Furthermore, existing devices generally suffer from uneven mixing of the agent and limited release range, and the agent is easily deactivated due to insufficient mixing before application, further reducing the treatment effect. These methods are inadequate for both the continuous treatment of basic water pollution and the response to sudden pollution events. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide an intelligent microbial slow-release device based on dynamic mixing to solve the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A smart microbial slow-release device based on dynamic mixing includes a water tank and a microbial quantitative dispensing device installed on the shore, and a water quality buoy station floating on the water surface. The outlet of the water tank is connected to the input of a water pump through a pipeline, and the output of the water pump is connected to the input of the microbial quantitative dispensing device through a pipeline. The output of the microbial quantitative dispensing device is connected to one end of a jet pipe, and the other end of the jet pipe is fixedly installed below the water quality buoy station. Several water-driven rotating jet pipes are equidistantly arranged on its lower surface. The microbial quantitative dispensing device is communicatively connected to the water quality buoy station.

[0006] In a preferred embodiment of this utility model, the microbial quantitative dispensing device has an activation box, a peristaltic pump and a control cabinet arranged at the top inside, and a mixing box and a metering pump arranged at the bottom inside. The microorganisms in the activation box are input into the mixing box through the peristaltic pump. The output end of the water supply pump is connected to the mixing box through a pipeline. The output end of the mixing box is connected to the input end of the metering pump through a pipeline. The output end of the metering pump is connected to one end of the injection pipe.

[0007] In a preferred embodiment of this utility model, a vortex mixer is provided inside the mixing tank.

[0008] In a preferred embodiment of this utility model, the water supply pump, the peristaltic pump, the vortex mixer, and the metering pump are all electrically connected to the control cabinet via guides.

[0009] In a preferred embodiment of this utility model, a sensor is installed on the top of the water quality buoy station, and a controller is installed above one side of it. The controller is electrically connected to the sensor via a wire, and the controller is communicatively connected to the control cabinet.

[0010] In a preferred embodiment of the present invention, the water-driven rotary nozzle is rotatably connected to the bottom of the jet pipe in a vertical direction, and wing tubes are provided on both the left and right sides of the water-driven rotary nozzle in a horizontal direction. Water outlet holes are provided on the circumferential surfaces of the two wing tubes near their ends in opposite directions.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This device monitors water quality data in real time using a water quality buoy station. The controller's dual-signal threshold algorithm (the main trigger signal responds to daily concentration exceedances, and the auxiliary trigger signal handles sudden concentration changes) precisely regulates the system, dynamically calculating the required amount of microbial agent and dilution ratio to achieve "on-demand delivery," significantly reducing agent waste. The vortex mixer inside the mixing tank uses high-speed shear at 2000-5000 rpm combined with 45-55℃ hot air mixing to form a microbial agent-gas-liquid suspension, significantly improving agent activity and dispersibility and preventing agent deactivation. The water-driven rotating nozzle automatically rotates through the jet thrust from the oppositely oriented outlets on both sides, overcoming the limitations of fixed spraying and greatly expanding the agent release range. This allows the agent to be evenly diffused over a wider area, while the water flow disturbance generated by the rotation promotes full integration of the agent with the water, preventing excessively high or low concentrations in certain areas and improving treatment uniformity. The system includes a 60-minute follow-up test and a gradient incremental mode (increasing the dose by 20% each time) to ensure water quality meets standards, taking into account both routine pollution control and emergency pollution response, and comprehensively improving the accuracy, efficiency and effectiveness of water body restoration.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Please refer to Figure 1-5 As shown, an embodiment of this application provides an intelligent microbial slow-release device based on dynamic mixing, including a water tank 1 and a microbial quantitative dispensing device 2 set on the shore, and a water quality buoy station 3 floating on the water surface. The water outlet of the water tank 1 is connected to the input of a water pump 5 through a pipeline, and the output of the water pump 5 is connected to the input of the microbial quantitative dispensing device 2 through a pipeline. The output of the microbial quantitative dispensing device 2 is connected to one end of a spray pipe 4, and the other end of the spray pipe 4 is fixedly installed below the water quality buoy station 3. Several water-driven rotating spray pipes 41 are equidistantly arranged on its lower surface. The microbial quantitative dispensing device 2 is communicatively connected to the water quality buoy station 3.

[0022] In a preferred embodiment of this utility model, the microbial quantitative dispensing device 2 is further provided with an activation box 21, a peristaltic pump 23 and a control cabinet 22 at the upper part of its interior, and a mixing box 24 and a metering pump 26 at the lower part of its interior. The microorganisms in the activation box 21 are input into the mixing box 24 through the peristaltic pump 23. The output end of the water pump 5 is connected to the mixing box 24 through a pipeline. The output end of the mixing box 24 is connected to the input end of the metering pump 26 through a pipeline. The output end of the metering pump 26 is connected to one end of the spray pipe 4.

[0023] In a preferred embodiment of the present invention, a vortex mixer 25 is further provided inside the mixing box 24.

[0024] In a preferred embodiment of this utility model, the water pump 5, the peristaltic pump 23, the vortex mixer 25 and the metering pump 26 are all electrically connected to the control cabinet 22 via guides.

[0025] In a preferred embodiment of this utility model, a sensor 31 is further provided on the top of the water quality buoy station 3, and a controller 32 is provided on the upper side of it. The controller 32 is electrically connected to the sensor 31 through a wire, and the controller 32 is communicatively connected to the control cabinet 22.

[0026] Specifically, the YR-FB3000 water quality buoy 3 uses sensor 31 to collect water quality data, which is then wirelessly transmitted (4G / NB-IoT) to controller 32 (embedded in the housing of the water quality buoy station 3). Controller 32 uses an STM32H743VI microcontroller 32, which collects data from water quality sensor 31 through its built-in 16-bit ADC, executes a dual-signal threshold judgment algorithm and dynamic dilution calculation, and outputs control signals to peristaltic pump 23 and metering pump 26. Controller 32 compares the dual-signal thresholds, which are the core of the dynamic control system and include a main trigger signal and an auxiliary trigger signal. When the real-time concentration exceeds the preset threshold (e.g., ammonia nitrogen > 2 mg / L, dissolved oxygen < 4 mg / L), the main trigger signal is triggered to solve the basic pollution problem of water bodies in daily life. When the rate of concentration change exceeds the gradient threshold (e.g., Δammonia nitrogen / Δt > 0.5 mg / L·h), the auxiliary trigger signal is triggered to deal with sudden pollution events.

[0027] The water quality buoy station 33 is powered by solar panels. Based on the signal threshold, it dynamically calculates the bacterial agent demand Q=K×(Cactual-CTarget)×V and the dilution ratio R=K×log(Cactual / CBenchmark). The command is then output to the peristaltic pump 23 (to adjust the bacterial solution flow rate from 0 to 500 mL / min) and the metering pump 26 (to control the water dilution ratio from 1:5 to 1:20) via RS-485. High-concentration bacterial agent enters the mixing tank 24 from the activation tank 214 via the peristaltic pump 236 to achieve the optimal dilution ratio for bacterial agent mixing. Clean water enters the mixing tank 24 from the water tank 1 via the metering pump 26. In the mixing tank 24, the bacterial agent and clean water are mixed by the vortex mixer 25 with high-speed shear at 2000~5000rpm and hot air at 45-55℃ to form a bacterial agent-gas-liquid suspension, which improves the dispersibility of the bacterial agent. Then, the release rate into the water body is controlled by the metering pump 26. The mixed bacterial agent is released into the water body through the spray pipe 4. The water quality is retested 60 minutes after the mixed bacterial agent is released. If the water quality does not meet the standard, the gradient incremental mode is activated (increasing the dosage by 20% each time).

[0028] This invention uses the sensor 31 of the water quality buoy station 3 to collect water quality data in real time. The controller 32 uses a dual-signal threshold algorithm (the main trigger signal responds to daily concentration exceeding the standard, and the auxiliary trigger signal responds to sudden changes in concentration) to accurately judge and dynamically calculate the required amount of bacterial agent and the dilution ratio, so as to achieve "on-demand delivery" and greatly reduce the waste of bacterial agent.

[0029] Inside the mixing chamber 24, the vortex mixer 25 uses high-speed shearing at 2000~5000 rpm combined with hot air at 45~55℃ to form a microbial agent-gas-liquid suspension, significantly improving the activity and dispersibility of the microbial agent. The water-driven rotary nozzle 41 rotates automatically through the thrust of the reverse water outlet 412, expanding the release range of the microbial agent and enhancing the diffusion effect.

[0030] The system features a 60-minute follow-up test and a gradient incremental mode (increasing the dose by 20% each time) to ensure water quality meets standards. It can effectively treat daily pollution and respond quickly to sudden pollution, comprehensively improving the accuracy and efficiency of water body restoration.

[0031] In a preferred embodiment of the present invention, the water-driven rotary nozzle 41 is rotatably connected to the bottom of the spray pipe 4 in the vertical direction, and the left and right sides of the water-driven rotary nozzle 41 are provided with wing pipes 411 in the horizontal direction. The two wing pipes 411 are provided with water outlet holes 412 in opposite directions near the ends of their circumferential surfaces.

[0032] Specifically, when the mixed bacterial agent is released into the water body through the spray pipe 4, the mixed bacterial agent enters the water-driven rotating spray pipe 41 and is then sprayed out from two completely opposite water outlets 412. The thrust of the mixed bacterial agent when it is sprayed drives the water-driven rotating spray pipe 41 to rotate, thereby expanding the spray range of the mixed bacterial agent and realizing the diffusion and slowing of the mixed bacterial agent, which is beneficial to further improving the water treatment effect.

[0033] The water-driven rotary nozzle 41 achieves multiple benefits through a unique structural design. Its vertical connection with the spray pipe 4, combined with the horizontally arranged wing pipes 411 on the left and right sides and the water outlet holes 412 in opposite directions at the ends, forms a highly efficient dynamic release mechanism.

[0034] When the mixed bacterial agent flows through the water-driven rotating nozzle 41, the bacterial agent is sprayed out from the water outlet 412 in opposite directions on both sides of the wing pipe 411. The nozzle is automatically rotated by the reaction force of the jet, and 360° all-round release can be achieved without additional power. This completely breaks through the problem of the limited release range of traditional fixed nozzles and significantly expands the coverage area of ​​the bacterial agent in the water.

[0035] During the rotation, the wing tube 411 rotates continuously with the spray tube 4, so that the bacterial agent can be evenly diffused in both horizontal and vertical directions, avoiding the phenomenon of excessively high or low local bacterial agent concentration caused by fixed-direction spraying in traditional devices, and ensuring that the bacterial agent is evenly distributed in all areas of the water body.

[0036] Meanwhile, the water flow disturbance generated by the rotation can promote the full integration of the bacterial agent with the water, prolong the suspension time of the bacterial agent in the water, reduce sedimentation loss, and improve the contact efficiency between microorganisms and pollutants.

[0037] In addition, the rotating structure design allows the bacterial agent to spread more flexibly to different water layers, taking into account the remediation needs of both the surface and lower water layers, further enhancing the purification effect of microorganisms on water bodies, and providing strong support for efficient treatment.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
