Description

Technical Field

[0001] This utility model relates to the field of water treatment membrane monitoring technology, and in particular to a water treatment membrane performance monitoring device. Background Technology

[0002] Water treatment membranes are materials with selective separation capabilities. The process of separating, purifying, and concentrating different components of wastewater using the selective separation capabilities of water treatment membranes is called membrane separation. It differs from traditional filtration in that water treatment membranes can separate at the molecular level, and this process is a physical process that does not require phase changes or the addition of additives. Ultrafiltration membranes are semi-permeable polymer membranes used in ultrafiltration processes to separate polymeric colloids or suspended particles of a certain size from a solution.

[0003] However, some existing water treatment membrane performance monitoring devices choose to monitor the outflow of water from the membrane module through a flow meter to reflect the water flow capacity. However, by only collecting the outflow of water through a flow meter, it can only reflect the change in the water flow resistance of the membrane (such as a decrease in flow rate may be due to membrane blockage), but it cannot distinguish the cause of blockage (whether it is inorganic scale, organic adhesion or microbial contamination), nor can it determine whether the membrane's retention capacity has declined, resulting in poor monitoring results. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water treatment membrane performance monitoring device, which solves the technical problem that some existing water treatment membrane performance monitoring devices only monitor the outflow rate of the membrane module to reflect the water flow capacity, which cannot distinguish the specific cause of membrane blockage or determine whether the membrane retention capacity has declined, resulting in poor monitoring effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A water treatment membrane performance monitoring device includes a monitoring device body with a circular groove on its operating table. A drainage groove is formed on the inner wall of the circular groove. A water storage tank is located at the upper end of the monitoring device body, and an outlet is located inside the water storage tank. A sealing plug is installed inside the outlet. A fixed frame is fixed on the operating table of the monitoring device body, directly opposite the circular groove. An auxiliary positioning frame is fixed on the inner wall of the fixed frame, and a limiting groove is formed on the inner wall of the auxiliary positioning frame. A water treatment membrane module is slidably installed within the limiting groove. An electronic flow meter is installed at the lower end of the water treatment membrane module. The outlet and the water treatment membrane module are located on the same vertical line. A threaded ring is threaded into the circular groove, and a filter screen is installed inside the threaded ring. Through the limiting cooperation of the water storage tank, the fixed frame, and the auxiliary positioning frame, the positioning of the water treatment membrane module is ensured to be accurate. Combined with the electronic flow meter and the filter screen, the device enables monitoring of the membrane module's effluent and preliminary judgment of the filtration effect, ensuring basic monitoring functions.

[0006] Preferably, the monitoring device body has a data display panel on its side wall, a connecting base is fixed on the side wall of the monitoring device body, a connecting cable is installed on the electronic flow meter, the connecting cable is connected to the connecting base, the data display panel, the connecting base and the connecting cable cooperate to transmit and display the flow data monitored by the electronic flow meter, which facilitates real-time reading of the membrane module's water output status and improves the efficiency of monitoring data acquisition.

[0007] Preferably, the water treatment membrane module has a positioning groove that matches the limiting groove, which further restricts the installation position of the water treatment membrane module, prevents the membrane module from shifting during monitoring, and improves the consistency and reliability of multiple monitoring data.

[0008] Preferred: A cover plate is snapped onto the water storage tank, and the cover plate is adapted to the opening of the water storage tank to cover the water storage tank. This can prevent external impurities from entering the water storage tank and contaminating the water used for monitoring, ensuring that the water quality standard is consistent for each monitoring and reducing the impact of water quality interference on the monitoring results.

[0009] Preferably, the side wall of the fixed frame is provided with a wire groove that extends along the height of the fixed frame to accommodate the wires connecting the electronic flow meter and the connector. This can prevent the wires from being messy and tangled, affecting the operation of the equipment or the stability of the water flow, making the equipment layout more orderly and reducing the risk of wire interference monitoring.

[0010] Preferably, the threaded ring engages with the circular groove and can be completely disengaged from the circular groove by twisting. The edge of the filter screen is fixedly connected to the inner wall of the threaded ring, which facilitates disassembly and cleaning of the filter screen or observation of impurities on the filter screen. This provides convenience for intuitively judging the filtration efficiency of the water treatment membrane module and helps to improve the monitoring results.

[0011] Preferably, the central axis of the fixing frame is collinear with the central axis of the circular groove, and the central axis of the outlet is collinear with the central axis of the water treatment membrane module. This ensures that the water flows vertically through the membrane module and falls accurately into the circular groove, reducing flow monitoring errors caused by water flow deviation and improving data accuracy.

[0012] Preferably, the limiting groove extends along the height direction of the auxiliary positioning frame, and the positioning groove extends along the height direction of the side wall of the water treatment membrane module. The cross-sectional shape of the limiting groove matches the positioning groove, further standardizing the sliding installation direction of the membrane module, ensuring that the membrane module is installed vertically, enhancing positioning accuracy, and ensuring monitoring stability.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This equipment monitors the outflow rate in real time through an electronic flow meter, directly reflecting the water flow efficiency of the membrane. It also traps impurities through a detachable filter screen, allowing for direct observation of the type and quantity of impurities. This helps to determine the filtration efficiency and the type of contamination, achieving dual monitoring of water flow capacity and filtration effect, thus improving the overall monitoring effect of the equipment. Second, this equipment uses the limiting grooves of the fixed frame and auxiliary positioning frame to match the positioning groove of the membrane module. Combined with the coaxial design of the monitoring component, it ensures the stability of the membrane module's installation position and verticality, avoids water flow disturbance caused by offset, and ensures that the relative positions of the membrane, water source, and flow meter are consistent during multiple monitoring, greatly reducing the measurement error caused by positioning deviation.

[0017] This application provides a water treatment membrane performance monitoring device, which effectively solves the problem that some existing water treatment membrane performance monitoring devices only monitor the water flow rate of the membrane module to reflect the water flow capacity. This is because they cannot distinguish the specific cause of membrane blockage or determine whether the membrane's retention capacity has declined, resulting in poor monitoring results. This device monitors the water flow rate in real time with an electronic flow meter, directly reflecting the membrane's water flow efficiency. It also uses a detachable filter screen to trap impurities, allowing for direct observation of the type and quantity of impurities, and assisting in judging the filtration efficiency and the type of pollution. This achieves dual monitoring of water flow capacity and filtration effect, improving the overall monitoring effect of the device.

[0018] Example like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application embodiment effectively solves the technical problem that some existing water treatment membrane performance monitoring devices only monitor the outflow rate of the membrane module to reflect the water flow capacity, which cannot distinguish the specific cause of membrane blockage or determine whether the membrane retention capacity has declined, resulting in poor monitoring effect. The overall idea is as follows: A water treatment membrane performance monitoring device includes a monitoring device body 1, a circular groove 2 is formed on the operating table of the monitoring device body 1, a drainage groove 3 is formed on the inner wall of the circular groove 2, a water storage tank 4 is formed at the upper end of the monitoring device body 1, a water outlet 18 is formed inside the water storage tank 4, and a sealing plug 19 is provided in the water outlet 18. A fixing frame 10 is fixed on the operating table of the monitoring device body 1, which is directly opposite to the circular groove 2. An auxiliary positioning frame 12 is fixed on the inner wall of the fixing frame 10. A limiting groove 13 is formed on the inner wall of the auxiliary positioning frame 12, and a water treatment membrane module is slidably installed in the limiting groove 13. 14. An electronic flow meter 16 is installed at the lower end of the water treatment membrane module 14. The outlet 18 is located on the same vertical line as the water treatment membrane module 14. A threaded ring 7 is installed in the inner thread of the circular groove 2, and a filter screen 8 is installed inside the threaded ring 7. The water storage tank 4 and the outlet 18 provide a stable water source for the water treatment membrane module 14. The cooperation of the fixing frame 10, the auxiliary positioning frame 12 and the limiting groove 13 realizes the precise sliding positioning of the water treatment membrane module 14. Combined with the vertical line design of the outlet 18 and the membrane module, it ensures that the water flows vertically and stably through the membrane module, avoiding water flow turbulence caused by membrane module misalignment. The electronic flow meter 16 is directly installed at the lower end of the membrane module, which can monitor the water flow rate in real time and reflect the water flow performance of the membrane module. The threaded ring 7 and the filter screen 8 in the circular groove 2 can not only receive filtered water and discharge it through the drainage tank 3, but also intercept impurities in the water, and make a preliminary judgment on the filtration effect of the membrane module. The overall structure works together to realize the basic monitoring of the membrane module performance, ensuring the stability of the monitoring process and the basic nature of the data.

[0019] Preferably, the monitoring device body 1 has a data display panel 6 on its side wall, and a connecting seat 9 is fixed on the side wall of the monitoring device body 1. A connecting cable 17 is installed on the electronic flow meter 16 and connected to the connecting seat 9. The real-time flow data monitored by the electronic flow meter 16 can be transmitted to the data display panel 6 through the connecting cable 17 and presented to the user intuitively. There is no need to manually read the flow meter data, which reduces human reading errors and can track the flow change trend in real time. It is convenient to quickly determine whether the water flow efficiency of the membrane module has decreased, which significantly improves the convenience of monitoring and the timeliness of data acquisition.

[0020] Preferably, the water treatment membrane module 14 is provided with a positioning groove 15, which is adapted to the limiting groove 13. The positioning groove 15 on the water treatment membrane module 14 is adapted to the limiting groove 13 of the auxiliary positioning frame 12. This design further restricts the lateral displacement of the membrane module on the basis of the basic positioning of the membrane module by the limiting groove 13, avoids the membrane module from shifting due to water flow impact or slight contact during the monitoring process, and ensures that the relative positions of the membrane module, the outlet 18 and the electronic flow meter 16 are completely consistent each time they are installed. This structurally ensures the comparability of multiple monitoring data and reduces measurement errors caused by positioning deviation.

[0021] Preferably, a cover plate 5 is snapped onto the water storage tank 4. The cover plate 5 is adapted to the opening of the water storage tank 4 to cover the water storage tank 4. When the equipment is idle, the cover plate 5 can prevent dust, impurities or microorganisms in the air from entering the water storage tank 4, avoid contaminating the monitoring water, and eliminate the need to clean the water storage tank before monitoring. This ensures that the initial state of the water source is consistent for each monitoring, eliminates misjudgment of membrane module performance caused by water pollution, and provides a stable water quality benchmark for monitoring results.

[0022] Preferably, the side wall of the mounting bracket 10 is provided with a wire groove 11, which extends along the height of the mounting bracket 10 to accommodate the wires connecting the electronic flow meter 16 and the connecting seat 9. The wires are constrained in the wire groove, which can prevent the wires from getting tangled on the membrane module or the mounting bracket and interfering with the water flow. It also prevents accidental contact with the wires during operation, which could lead to loosening or detachment of the connection, thus ensuring the stability of data transmission. At the same time, it makes the equipment wiring layout neat and easy to quickly identify the wires during maintenance, thereby improving the safety and cleanliness of equipment operation.

[0023] Preferably, the threaded ring 7 is threadedly engaged with the circular groove 2 and can be completely disengaged from the circular groove 2 by twisting. The edge of the filter screen 8 is fixedly connected to the inner wall of the threaded ring 7. After monitoring, the threaded ring 7 can be easily disassembled by twisting. On the one hand, it is convenient to thoroughly clean the impurities trapped on the filter screen 8. On the other hand, it is possible to directly observe the type, quantity and shape of the impurities, which helps to judge the filtration efficiency of the membrane module and provides an intuitive basis for diagnosing the type of membrane module fouling, thus expanding the monitoring dimensions of the equipment.

[0024] Preferably, the central axis of the fixing frame 10 is collinear with the central axis of the circular groove 2, and the central axis of the outlet 18 is collinear with the central axis of the water treatment membrane module 14, forming a coaxial design. This structure ensures that when the water in the water storage tank 4 falls vertically from the outlet 18, it can accurately enter the central area of ​​the membrane module, avoiding local turbulence caused by the water flow deviating and impacting the edge of the membrane module. At the same time, the filtered water can fall vertically into the circular groove 2, reducing the situation of water splashing out or flowing away along the wall of the circular groove, ensuring that the flow rate measured by the electronic flow meter 16 is consistent with the actual flow rate passing through the membrane module, significantly reducing the measurement error caused by the deviation of the water flow path, and improving the accuracy of the flow data.

[0025] Preferably, the limiting groove 13 extends along the height direction of the auxiliary positioning frame 12, and the positioning groove 15 extends along the height direction of the side wall of the water treatment membrane module 14. The cross-sectional shape of the limiting groove 13 matches the positioning groove 15. During installation, the membrane module can slide precisely along the extension direction of the limiting groove 13, avoiding the tilting of the membrane module caused by tilting insertion. The matching cross-sectional shape further restricts the rotation or torsion of the membrane module, ensuring that the membrane module always remains vertical, so that the water flow is evenly distributed on the membrane surface, avoiding excessive local flux or measurement area deviation caused by the tilting of the membrane module. Structurally, it ensures the stability of the membrane module's working state and improves the reliability of monitoring data.

[0026] To address the problems existing in the prior art, this utility model provides a water treatment membrane performance monitoring device. This device monitors the outflow rate in real time through an electronic flow meter, directly reflecting the water flow efficiency of the membrane. It also traps impurities through a detachable filter screen, allowing for direct observation of the type and quantity of impurities, and assisting in judging the filtration efficiency and pollution type. This achieves dual monitoring of water flow capacity and filtration effect, improving the overall monitoring effect of the device.

[0027] Working principle: First, when using the water treatment membrane module 14, place it in the limiting groove 13. Then, install the electronic flow meter 16 at the lower end of the water treatment membrane module 14 and connect the connecting wire 17 on the electronic flow meter 16 to the connecting seat 9. Next, install the threaded ring 7 inside the circular groove 2. At this time, the sealing plug 19 in the outlet 18 can be removed. The water in the water storage tank 4 will flow into the water treatment membrane module 14 through the outlet 18. After being filtered by the water treatment membrane module 14, it will fall into the circular groove 2 and then be discharged through the filter screen 8 and the drain trough 3, completing one monitoring cycle. The second step involves the electronic flow meter 16 monitoring the flow rate of the water treatment membrane module 14. The monitoring results are displayed on the data display panel 6. The flow rate measured per unit time can be compared with the flow rate data at the factory to verify the health performance of the water treatment membrane module 14. After each monitoring is completed, the threaded ring 7 can be removed from the inside of the circular groove 2. By observing whether there are impurities on the filter screen 8, the water treatment effect of the water treatment membrane module 14 can be verified, further improving the accuracy of equipment monitoring.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
