[0002] A closed process water system is an industrial water circulation system. Its main feature is that water is circulated in a closed system of pipes and equipment and does not directly contact the external environment. In a closed process water system, although the system is closed, there is still a risk of microbial growth. In order to prevent the growth and reproduction of microorganisms and thus ensure the long-term and efficient operation of the system, a closed process water system microbial control device is required.

[0003] Microbial control devices can be divided into many types, including online dosing systems, ultraviolet sterilizers and electrochemical sterilization devices. Through reasonable selection and combination, microbial control devices can provide comprehensive protection for closed process water systems and improve operating efficiency.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Please refer to the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a microbial control device suitable for a closed process water system, comprising a mixing barrel 1, a support plate 2 is fixedly connected to the outer wall of the mixing barrel 1, a quantitative component is arranged on the top of the support plate 2, a metering pump 23 is fixedly connected to the outer wall of the mixing barrel 1, and is used to transport the mixed liquid medicine to the closed process water system to achieve accurate delivery and recycling of medicines, a sensor module 35 is fixedly connected inside the mixing barrel 1, and the sensor module 35 is electrically connected to a control system; The quantitative component includes a shell 15, the bottom of which is fixedly connected to the top of the support plate 2, which plays a supporting and stabilizing role; the top of the support plate 2 is fixedly connected to a shell 29, which is used to cooperate with the shell 15 to install the quantitative column 11 and provide an operating space. The quantitative column 11 is rotatably connected inside the shell 15 and the shell 29, and a cavity 12 is opened inside the quantitative column 11 for temporarily storing medicines to achieve quantitative delivery. A discharge pipe 13 is fixedly connected inside the shell 15, and one end of the discharge pipe 13 is fixedly connected inside the mixing barrel 1, which is convenient for transporting the medicines in the cavity 12 to the mixing barrel 1 for mixing. A storage barrel 6 is fixedly connected to the top of the shell 15 for storing medicines that inhibit microorganisms to ensure the continuous operation of the device. An electric push rod 3 is fixedly connected to the top of the support plate 2, and the function of the electric push rod 3 is to push the piston 7 to perform a linear sliding operation; a hollow tube 4 is fixedly connected to the top of the support plate 2, and one end of the hollow tube 4 is fixedly connected to the inside of the shell 29, which serves as a sliding guide structure for the piston 7. The piston 7 is slidably connected inside the hollow tube 4, and can be moved inside the hollow tube 4 by the drive of the electric push rod 13, squeezing the medicine in the cavity 12 into the discharge pipe 13, thereby realizing the precise quantitative delivery of the medicine. A driving assembly is provided at one end of the quantitative column 11, and the driving assembly includes an electric push rod 28, one end of which is rotatably connected to the top of the support plate 2, and the quantitative column 11 is driven to rotate by the telescopic action of the electric push rod 28. The output end of the electric push rod 28 is rotatably connected to a connecting rod 10, one end of which is fixedly connected to one end of the quantitative column 11. The function of the connecting rod 10 is to convert the linear motion of the electric push rod 28 into the rotational motion of the quantitative column 11, thereby completing the quantitative operation of the medicine; Specifically, when performing the quantitative drug dispensing operation, the storage barrel 6 stores specific drugs for inhibiting the growth of microorganisms. By starting the electric push rod 28, its output end gradually extends, driving the connecting rod 10 to rotate, and the connecting rod 10 further drives the quantitative column 11 to rotate accurately, so that the cavity 12 inside the quantitative column 11 is vertically docked with the outlet of the storage barrel 6. At this time, the drugs inside the storage barrel 6 fall accurately into the cavity 12 under the action of gravity. Subsequently, the output end of the electric push rod 28 is retracted to the initial position, and the connecting rod 10 moves in the opposite direction to drive the quantitative column 11 to reset, so that the cavity 12 is re-sealed. At the same time, the output end of the electric push rod 13 extends, and by pushing the piston 7 to slide axially inside the hollow tube 4, the drugs stored in the cavity 12 are accurately squeezed from the hollow tube 4 into the discharge pipe 13, and the drugs are transported to the mixing barrel 1 along the discharge pipe 13 to be fully mixed with other components. The entire process achieves accurate metering and effective delivery of drugs, ensuring the efficiency of dispensing operations and the accuracy of proportions, thereby significantly improving the performance and reliability of microbial control devices.

[0023] Please refer to the attached Figure 4 and attached Figure 5The top of the mixing barrel 1 is fixedly connected with a motor 14, which provides rotational power for the mixing barrel 1 and is used to drive the mixing device to operate. The output end of the motor 14 is fixedly connected with a rotating shaft 15, and the outer wall of the rotating shaft 15 is fixedly connected with cone barrels 16 arranged in a ring array. The function of the cone barrels 16 is to guide the water flow and the medicine to flow from the smaller end of the cone barrel 16 to the larger end, thereby increasing the rotation speed of the water flow and improving the mixing efficiency. The outer wall of the rotating shaft 15 is fixedly connected with a turntable 17, which drives other components on it to operate synchronously through rotation, thereby realizing multi-dimensional disturbance of the water flow inside the mixing barrel 1. The outer wall of the turntable 17 is fixedly connected with baffle 18 and baffle 2 19. When the turntable 17 rotates, baffle 18 and baffle 2 19 cut the water flow inside the mixing barrel 1 in a vertical direction, effectively increasing the flow path of the water flow and strengthening the mixing effect of the medicine and water. A fixed ring 20 is fixedly connected to the top of the turntable 17. The fixed ring 20 rotates under the drive of the rotating shaft 15, further disturbing the water flow inside the mixing barrel 1 to improve the mixing uniformity. An opening 21 is provided inside the fixed ring 20. The opening 21 allows the water flow and the medicine to be divided into multiple small streams when passing through, increasing the contact area and promoting sufficient mixing. A cutting blade 22 is fixedly connected to the outer wall of the fixed ring 20. The cutting blade 22 cuts the water flow in a horizontal direction when rotating, and cooperates with the vertical cutting of the baffle to further enhance the mutual mixing effect of the water flow and the medicine, thereby significantly improving the dissolution and distribution efficiency of the medicine; Specifically, when mixing the medicines in the mixing barrel 1, firstly, a proper amount of water is injected into the mixing barrel 1 through the water source, and then the motor 14 is started, and its output end drives the connected shaft 15 to rotate at a high speed. The shaft 15 further drives the cone barrel 16 to rotate synchronously. The unique structural design of the cone barrel 16 guides the water flow and medicines in the mixing barrel 1 from the smaller end to the larger end, and gradually accelerates during the flow process, thereby significantly increasing the rotation speed of the water flow and forming a strong vortex effect. At the same time, the rotation of the shaft 15 also drives the turntable 17 and the fixed ring 20 fixed thereon to rotate synchronously. The baffle 1 18 and the baffle 2 19 on the turntable 17 repeatedly cut the water flow in the vertical direction, and the fixed ring 20 realizes multiple cutting in the horizontal direction through the cutting blade 22. Through the multi-dimensional cutting action, the water flow and the medicine are integrated in the mixing barrel 1 in a more sufficient and efficient manner, which greatly improves the mixing rate of the medicine and water, and finally achieves the effect of significantly improving the mixing efficiency. This design ensures uniform mixing of drugs and water, providing stable and reliable drug solution ratio support for subsequent microbial control.

[0024] Please refer to the attached Figure 6 and attached Figure 7The mixing barrel 1 is rotatably connected to a sleeve 26, which rotates in the mixing barrel 1 to drive the synchronous movement of related components to improve the internal cleaning effect. The outer wall of the sleeve 26 is fixedly connected to a frame 28, which provides support for the rotation of the sleeve 26 and drives the cleaning components such as the scraper 33 to work by cooperating with the sleeve 26. A bevel gear 27 is fixedly connected to the top of the sleeve 26. The bevel gear 27 meshes with the bevel gear 1 25 through gear transmission to provide rotational power for the sleeve 26. A motor 24 is fixedly connected to the top of the mixing barrel 1. The motor 24 provides a rotational driving force through its output end. The output end of the motor 24 is fixedly connected to the bevel gear 25. The bevel gear 1 25 meshes with the outer wall of the bevel gear 27 to achieve power transmission, so that the sleeve 26 and the frame 28 can rotate synchronously, providing continuous mechanical action for cleaning the inner wall of the mixing barrel 1. A fixed seat 29 is fixedly connected to the inside of the frame 28. The fixed seat 29 provides a stable installation foundation for the cleaning mechanism. A slope 30 is arranged on the top of the frame 28. The slope 30 is used to adjust the angle of the connecting plate 31, thereby affecting the contact area between the scraper 33 and the inner wall of the mixing barrel 1. A connecting plate 31 is provided on the top of the fixed seat 29. The connecting plate 31 provides support for the fixation of the scraper 33. An adjustment slot 32 is provided inside the connecting plate 31. The adjustment slot 32 allows the connecting plate 31 to move along the inclined surface 30 so as to flexibly adjust the position and angle of the scraper 33 to enhance the cleaning effect. A scraper 33 is fixedly connected to one side of the connecting plate 31. The scraper 33 is used to scrape off the attachments on the inner wall of the mixing barrel 1. The position and angle of the scraper 33 can be adjusted to achieve precise matching. An adjusting bolt 34 is threadedly connected to the inside of the fixed seat 29. The adjusting bolt 34 controls the fixing state of the connecting plate 31 on the fixed seat 29 by rotation. The user can adjust the cleaning position and strength of the scraper 33 by adjusting the bolt 34, thereby ensuring that the inner wall of the mixing barrel 1 is thoroughly cleaned. The connecting plate 31 is fixedly connected to the fixed seat 29 by the adjusting bolt 34, ensuring the stability and reliability of the cleaning component during operation; Specifically, in the process of cleaning the inside of the mixing barrel 1, the motor 24 is first started, and its output end drives the bevel gear 1 25 to rotate at a high speed. The rotation of the bevel gear 1 25 is further driven by meshing transmission to rotate the bevel gear 2 27 connected thereto, thereby driving the sleeve 26 to rotate in a synchronous manner. The rotation of the sleeve 26 is transmitted to the scraper 33 through the fixed frame 28, so that the scraper 33 can perform a full range of efficient cleaning of the inner wall of the mixing barrel 1. The scraper 33 is close to the inner wall of the mixing barrel 1 during the rotation process, scraping off the attached residues to ensure the cleaning effect inside the barrel. When it is necessary to adjust the contact area between the scraper 33 and the inner wall of the mixing barrel 1 to meet different cleaning requirements, the operator can first loosen the adjusting bolt 34. At this time, the scraper 33 is adjusted in position along the inclined surface 30 set on the frame 28 through the connecting plate 31, thereby realizing flexible adjustment of the contact area. When the scraper 33 reaches the predetermined position, tightening the adjusting bolt 34 can lock it firmly to ensure that the scraper 33 remains stable during the cleaning process. This design can achieve the effect of quickly and thoroughly cleaning the inner wall of the mixing barrel 1, while being easy to operate, thereby improving the cleaning efficiency and ease of use of the equipment and providing a clean working environment for subsequent mixing operations.

[0025] Please refer to the attached Figure 3 , the control system comprises: Central processing unit: responsible for receiving real-time data transmitted by the sensor module and processing the data. The data includes relevant parameters such as microbial concentration, temperature, flow rate, etc. The CPU compares the processed data with the preset pollution index threshold. If the monitored microbial concentration exceeds the preset threshold, the CPU will issue an instruction according to the set logic to start the metering pump to release the bactericide into the water flow. The CPU is also connected to the PLC controller to ensure real-time control and scheduling of the system.

[0026] PLC controller: The PLC controller in the control system undertakes the logical control task of the system. It is mainly used to execute the control instructions transmitted by the CPU and adjust the system operation according to real-time data. The functions of the PLC controller include: receiving and processing instructions from the CPU, executing automatic control, such as starting or stopping the work of the metering pump. According to the monitored microbial concentration, adjust the amount and time of the bactericide to ensure accurate control of water quality. Through the PLC controller, the system can be flexibly adjusted under different working conditions to adapt to closed process water systems of different sizes and complexities.

[0027] Communication module: The communication module is used to exchange data between the sensor module, PLC controller and other devices. Through the communication module, the sensor module transmits the collected microbial concentration data to the control system in real time, and the PLC controller receives and processes this information through the data interface. This module ensures accurate data transmission, avoids information loss or mistransmission, and ensures that the control system can respond in real time. The communication module can support wired or wireless data transmission methods to adapt to different industrial environments.

[0028] Metering pump control module: The metering pump control module is responsible for receiving instructions from the PLC controller and accurately adjusting the working state of the metering pump. When the microbial concentration exceeds the standard, the PLC controller will instruct the metering pump to start, extract and inject a fixed amount of fungicide from the liquid storage tank according to the set flow rate. The control system of the metering pump can accurately adjust the injection amount of fungicide to ensure that the fungicide is evenly mixed with the water body and accurately delivered. This module supports high-precision flow regulation function to meet the needs of different pollution indices and different types of microbial control.

[0029] Display and operation interface: In this embodiment, the control system is provided with a display and operation interface for operators to monitor and adjust the system. The interface can display the working status of the system in real time, including water quality monitoring data, alarm information and equipment operation status. Users can view the current microbial contamination index and water quality through the interface and make timely adjustments. Operators can also set the pollution index alarm threshold through the interface. The default value is 10, and it can be adjusted according to actual needs to better adapt to different working environments. The display interface also provides a historical data viewing function, which is convenient for operators to trace system operation data and conduct fault analysis and maintenance.

[0030] Power management unit: The power management unit provides stable power support for the entire control system to ensure that the system does not malfunction due to power problems during operation. The unit has a power-off protection function. When the power is interrupted, the system can save the current state and continue to work normally after the power is restored. The power management unit can adjust the power output to ensure that the power needs of each component are fully guaranteed while avoiding overload or waste. The control system automatically determines the water quality value based on the microbial concentration data from the sensor module, and controls the amount of disinfectant added according to the set threshold; Specifically, the sensor module monitors the concentration of microorganisms in the process water in real time and transmits the data to the central processing unit. The central processing unit compares the received data with the preset pollution index threshold. When the microbial concentration exceeds the set threshold, the PLC controller is triggered to control the metering pump. The metering pump accurately injects the bactericide into the water flow according to the instructions of the PLC controller to ensure that the water quality meets the safety standards. The system provides real-time feedback through the display and operation interface, and allows operators to adjust the system settings to ensure that the water quality is controlled in time. The sensor module can be replaced with different types of microbial sensors according to different detection requirements. The software of the control system can be upgraded to expand its functions to ensure that the system can adapt to the ever-changing technical requirements and working environment. The specifications of the metering pump and its control module can be selected according to the actual application scenario to adapt to closed process water systems of different sizes.
