[0002] Bio-fermentation purification is a technical process for separating and purifying target products from microbial metabolites (such as antibiotics, enzymes, and organic acids). During the purification process, the proliferation of contaminating microorganisms severely affects the purification effect. Therefore, it is necessary to add antimicrobial agents to the stock solution to inhibit the growth of contaminating microorganisms. Antimicrobial agents are a key auxiliary means of controlling microbial contamination in fermentation purification processes, and their rational application requires a balance between antimicrobial efficiency and product safety. Therefore, how to accurately add antimicrobial agents to the stock solution is a technical problem that urgently needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic and precise metering dosing system for inhibiting the proliferation of miscellaneous bacteria, so as to solve the technical problem of insufficient precision and uniformity in the addition of antibacterial agents during the fermentation and purification process in the prior art.

[0005] A uniform storage tank with a mixing chamber inside; the upper end of the uniform storage tank is provided with a raw liquid inlet and multiple antibacterial agent inlets connected to the mixing chamber, and the lower end is provided with a discharge port;

[0006] Multiple feed meters are fixedly installed at the top of the uniform storage tank and correspond one-to-one with the multiple antibacterial agent inlets. Each feed meter has a flow valve and a metering pump arranged vertically and connected to each other. The lower end of the metering pump is connected to the antibacterial agent inlet.

[0007] A stirring mechanism is installed on the homogenizing tank; the stirring shaft of the stirring mechanism is located inside the homogenizing tank and is rotatably connected to the homogenizing tank, and is used to mix the stock solution and the antibacterial agent.

[0009] In one possible implementation, the system further includes an online detector installed inside the uniform storage tank and a control unit connected to the online detector. The flow valve and the metering pump are both connected to the control unit. The online detector monitors the bacterial concentration in the uniform storage tank and feeds the data back to the control unit. The control unit analyzes and processes the data and adjusts the operating parameters of the flow valve and the metering pump.

[0010] In one possible implementation, the number of online detectors is multiple, arranged at intervals within the uniform storage tank.

[0011] In one possible implementation, the control valve is electrically connected to the control unit.

[0012] In one possible implementation, the feed meter includes a vertically arranged main pipe, with the flow valve and the metering pump fixedly installed at the upper and lower ends of the main pipe, respectively.

[0013] In one possible implementation, the main pipeline is provided with connecting flanges at both the upper and lower ends, and the two connecting flanges are connected to the flow valve and the metering pump.

[0014] In one possible implementation, the raw liquid inlet and the plurality of antibacterial agent inlets are arranged in a ring or in a rectangular array; the upper end of the uniform storage tank is provided with a mounting hole, which is located at the center of the raw liquid inlet and the plurality of antibacterial agent inlets, and the stirring shaft of the stirring mechanism is rotatably connected to the mounting hole.

[0018] The beneficial effects of the automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria provided by this utility model are as follows: Compared with the prior art, the automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria of this utility model first connects the stock solution to the stock solution inlet, and connects multiple feed meters to various different antibacterial agents, while closing the control valve; the stock solution enters the mixing chamber of the homogenizing tank through the stock solution inlet, and the corresponding feed meter is opened, allowing the required type of antibacterial agent to pass through the feed meter and the antibacterial agent inlet into the mixing chamber; the antibacterial agent is precisely metered by the dual metering of the flow valve and the metering pump on the feed meter, improving the accuracy of antibacterial agent addition; simultaneously, the stirring mechanism is activated, causing the stirring shaft in the mixing chamber to rotate at high speed, thoroughly mixing the stock solution and the antibacterial agent, making the mixture more uniform. Finally, the control valve is opened, allowing the mixture to be discharged through the outlet, and then smoothly enters the next process. During use, when different types of antibacterial agents need to be added, other flow valves and metering pumps are closed to seal the feed metering device, while the corresponding flow valve and metering pump are opened to allow the required antibacterial agent to be smoothly and accurately added to the mixing chamber, thereby improving the accuracy of antibacterial agent use. Throughout the process, the amount of antibacterial agent added is precisely controlled by the flow valves and metering pumps on the feed metering device, thus matching the components in the stock solution, and the stirring mechanism ensures a more uniform mixture between the stock solution and the antibacterial agent.

[0029] Please refer to Figures 1 to 3. The present invention provides an automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria. The automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria includes a uniform storage tank 10, a feed metering device 20, a stirring mechanism 30, and a control valve 40. The uniform storage tank 10 has a mixing chamber 11 inside. The upper end of the uniform storage tank 10 has a stock solution inlet 12 connected to the mixing chamber 11 and multiple antibacterial agent inlets 13, and the lower end has a discharge port 14. Multiple feed metering devices 20 are fixedly installed at the upper end of the uniform storage tank 10 and correspond one-to-one with the multiple antibacterial agent inlets 13. The metering device 20 has a flow valve 21 and a metering pump 22 that are arranged vertically and connected to each other. The lower end of the metering pump 22 is connected to the antibacterial agent inlet 13. The stirring mechanism 30 is installed on the homogenizing tank 10. The stirring shaft 31 of the stirring mechanism 30 is located inside the homogenizing tank 10 and is rotatably connected to the homogenizing tank 10 for mixing the stock solution and the antibacterial agent. The control valve 40 is fixedly installed at the lower end of the homogenizing tank 10 and is connected to the discharge port 14. The control valve 40 is used to control the opening or closing of the discharge port 14.

[0030] This invention provides an automatic precision metering and dosing system for inhibiting the proliferation of miscellaneous bacteria. Compared with existing technologies, the system first connects the stock solution to the stock solution inlet 12, and multiple feed meters 20 are connected to various different antibacterial agents, while the control valve 40 is closed. The stock solution enters the mixing chamber 11 of the uniform storage tank 10 through the stock solution inlet 12, and the corresponding feed meter 20 is opened. The required type of antibacterial agent passes through the feed meter 20 and the antibacterial agent inlet 13 into the mixing chamber 11. The antibacterial agent is precisely metered by the dual metering of the flow valve 21 and the metering pump 22 on the feed meter 20, improving the accuracy of the antibacterial agent addition. At the same time, the stirring mechanism 30 is activated, causing the stirring shaft 31 in the mixing chamber 11 to rotate at high speed, thoroughly mixing the stock solution and the antibacterial agent, making the mixture more uniform. Finally, the control valve 40 is opened, allowing the mixture to be discharged through the outlet 14 and then smoothly enter the next process. During use, when different types of antibacterial agents need to be added, the other flow valves 21 and metering pumps 22 are closed to block the feed metering device 20, while the corresponding flow valves 21 and metering pumps 22 are opened to allow the required antibacterial agent to be smoothly and accurately added to the mixing chamber 11, thereby improving the accuracy of antibacterial agent use. Throughout the process, the amount of antibacterial agent added is precisely controlled by the flow valves 21 and metering pumps 22 on the feed metering device 20, thus matching the components in the stock solution, and the stirring mechanism 30 ensures a more uniform mixing between the stock solution and the antibacterial agent.

[0031] Meanwhile, the design of the uniform storage tank 10 ensures sufficient storage space for both the stock solution and the antibacterial agent, preventing insufficient supply from affecting the dosing process. During long-term operation, the system also features a self-monitoring and feedback mechanism.

[0032] Please refer to Figure 1. As a specific embodiment of the automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria provided by this utility model, it also includes an online detector 50 installed in the uniform storage tank 10 and a control unit connected to the online detector 50. The flow valve 21 and the metering pump 22 are both connected to the control unit. The online detector 50 monitors the bacterial concentration in the uniform storage tank 10 and feeds the data back to the control unit. The control unit analyzes and processes the data and adjusts the operating parameters of the flow valve 21 and the metering pump 22. When the online detector 50 detects a high concentration of miscellaneous bacteria in the uniform storage tank 10, it quickly feeds this information back to the control unit. The control unit quickly analyzes and processes the data, determining that the trend of miscellaneous bacteria proliferation is increasing. The control unit sends a signal to adjust the flow valve 21, increasing its opening degree to accelerate the inflow rate and flow of the antibacterial agent, thereby precisely inhibiting the reproduction of miscellaneous bacteria. Simultaneously, the control unit also adjusts the operating parameters of the metering pump 22 accordingly, increasing the dosage of the antibacterial agent and precisely controlling the amount of antibacterial agent added to better inhibit the proliferation of miscellaneous bacteria. As time goes on, the online detector 50 continuously monitors the changes in the concentration of miscellaneous bacteria. Based on the feedback data, the control unit continuously fine-tunes the operating parameters of the flow valve 21 and the metering pump 22 to maintain effective inhibition of the proliferation of miscellaneous bacteria and ensure the stability and efficiency of subsequent operations.

An observation window is also provided on one side of the main pipe 23, through which the flow of the antibacterial agent inside the main pipe 23 can be clearly seen, facilitating the operator's timely understanding of the feeding status. A pressure sensor is installed in the middle of the main pipe 23 to monitor the pressure changes of the antibacterial agent inside the main pipe 23 in real time, providing data support for the stability of the feeding process. The flow valve 21 adjusts the flow rate of the antibacterial agent in the main pipe 23 by precisely controlling the opening of the valve 40, ensuring the uniformity of the feeding. The metering pump 22 accurately delivers the antibacterial agent into the main pipeline 23 according to the set metering parameters, thereby achieving precise metering of the amount of material passed through.

[0036] Please refer to Figures 1 to 3. As a specific embodiment of the automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria provided by this utility model, the main pipeline 23 is equipped with connecting flanges 24 at both its upper and lower ends. The two connecting flanges 24 are connected to the flow valve 21 and the metering pump 22; the connecting flanges 24 securely and reliably connect the main pipeline 23 to the flow valve 21 and the metering pump 22. To ensure the sealing of the entire material metering system, sealing gaskets are installed at the connecting flanges 24 to prevent leakage of the antibacterial agent.

[0037] Please refer to Figures 1 to 3. As a specific embodiment of the automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria provided by this utility model, the stock solution inlet 12 and multiple antibacterial agent inlets 13 are arranged in a uniform ring or a rectangular array. A mounting hole 15 is provided at the upper end of the uniform storage tank 10, located at the center of the stock solution inlet 12 and the multiple antibacterial agent inlets 13. The stirring shaft 31 of the stirring mechanism 30 is rotatably connected to the mounting hole 15. The uniform ring or rectangular array arrangement fully utilizes the space of the uniform storage tank 10 and facilitates the uniform addition of the stock solution and antibacterial agent. The stirring mechanism 30 includes a motor assembly, etc., and its output shaft is connected to the stirring shaft 31. The stirring shaft 31 passes through the mounting hole 15 and enters the uniform storage tank 10. The high-speed rotation of the stirring blades on the stirring shaft 31 ensures uniform mixing of the stock solution and antibacterial agent.

[0038] Please refer to Figures 2 and 3. As a specific embodiment of the automatic precise metering and dosing system for inhibiting the proliferation of miscellaneous bacteria provided by this utility model, the upper end of the uniform storage tank 10 is also fixedly equipped with a feed pipe 16, the lower end of which is connected to the raw material inlet 12.

The radial dimension of the straight cylindrical section 17 remains constant, forming a regular cylindrical shape, providing a stable mixing space for the raw material and antibacterial agent. The straight cylindrical section 17 and the converging cylindrical section 18 are closely connected, achieving a transition from a relatively large storage space to a gradually narrowing discharge channel during their vertical arrangement. After the raw material and antibacterial agent enter the converging cylindrical section 18 from the straight cylindrical section 17, due to the gradual decrease in the radial dimension of the converging cylindrical section 18, the raw material and antibacterial agent gradually gather towards the center under the action of gravity, and finally flow smoothly out from the discharge port 14 at the lower end. In the overall structural design of the uniform storage tank 10, the combination of the straight cylindrical section 17 and the converging cylindrical section 18 not only ensures sufficient storage of the original liquid and antibacterial agent, but also achieves efficient discharge function.
