[0002] In the field of water treatment and membrane separation technology, reverse osmosis membrane non-woven fabric filtration equipment is a core component, and its performance directly affects the water purification effect and production efficiency. After years of development, the technology in this field has undergone three generations of iteration. Traditional reverse osmosis membrane filtration equipment generally suffers from problems such as cumbersome filter element replacement and low detection efficiency. Moreover, existing equipment mostly uses bolts to fix the filter element, which requires disassembling multiple parts during replacement, which is time-consuming and labor-intensive, affecting the normal use of the filter element. Utility Model Content

[0009] As a preferred embodiment, a control valve is movably installed on the external side of the delivery pipe connected to the right side of the filter housing, and an adjustment valve is movably installed on the surface of the discharge pipe.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0011] 1. The filter element of this utility model is positioned vertically by the vertical snap-fit groove of the positioning seat. When replacing it, there is no need to use tools such as screwdrivers and wrenches.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example
[0019] Please see Figure 1 As shown, this utility model provides a reverse osmosis membrane nonwoven fabric high-efficiency filtration testing device that facilitates quick filter element replacement. It includes a filter box 1, a testing box 3 connected to the right side of the filter box 1 via a conveying pipe 2, a sampling pipe 4 connected to the top of the testing box 3, and a discharge pipe 5 connected to the lower right side of the testing box 3. Positioning seats 6 are fixedly installed on both the front and rear sides of the inner cavity of the filter box 1. The positioning seats 6 have vertically opened snap-fit grooves inside, and filter elements 7 are vertically snap-fitted inside the snap-fit grooves. An upper snap-fit bracket 8 is snap-fitted to the upper end of the filter element 7. Support springs 9 are installed on both sides of the top of the upper snap-fit bracket 8. A top cover plate 10 is fixedly installed on the upper end of the support springs 9. The front and rear sides of the top cover plate 10 are snap-fitted to the outside of the filter box 1.
[0020] In this technical solution, the filter element 7 is positioned vertically through the vertical snap-fit groove of the positioning seat 6. When replacing it, there is no need to use tools such as screwdrivers and wrenches. Simply remove the top cover 10 from the outside of the filter box 1 to release the fixing constraint on the filter element 7, which greatly saves disassembly time. The filter element 7 and the upper snap-fit bracket 8 are connected by snap-fit, and the upper snap-fit bracket 8, the top cover 10, and the filter box 1 adopt easy separation structures such as plug-in and snap-fit. This modular design ensures that the components do not interfere with each other during disassembly, avoiding the disassembly difficulties caused by the complex interlacing of parts in traditional equipment. Example
[0021] Based on Embodiment 1, this utility model is as follows: Figure 2 As shown, side plates 11 are fixedly installed on both the front and rear sides of the upper end of the filter box 1. The bent part of the top cover plate 10 is attached to the outside of the side plates 11 and connected by the plug rod 12. A drive motor 13 is fixedly installed at the center of the top of the detection box 3. The output shaft of the drive motor 13 passes through the inside of the detection box 3 and a rotating shaft 14 is fixedly installed. A stirring rod 15 is installed in a ring on the surface of the rotating shaft 14.
[0022] Adopting such Figure 1 The technical solution shown uses the side plate 11 and the top cover plate 10 to be bent together and connected by the plug rod 12, replacing the traditional bolt and nut fastening method. This design reduces the thread hole processing steps and tightening operations during assembly, shortens the production line cycle time, and reduces labor costs. When the filtered liquid enters the detection chamber 3 through the delivery pipe 2, the stirring rod 15 rotates with the rotating shaft 14. The stirring of the stirring rod 15 can accelerate the diffusion and fusion of the reagent and the fluid, shorten the reaction time, and improve the detection efficiency.
[0023] Secondly, in the technical solution, a pressure sensor 16, a flow sensor 17, and a water quality sensor 18 are respectively installed on the rear and right sides of the inner cavity of the detection chamber 3. The pressure sensor 16, the flow sensor 17, and the water quality sensor 18 are all electrically connected to an external controller.
[0024] Its adoption is as follows Figure 1 The technical solution shown includes a pressure sensor 16 that detects pressure changes within the housing 3 to reflect the degree of clogging of the filter element 7 in real time. When the pressure exceeds a threshold, it automatically triggers a filter element 7 replacement reminder to prevent a decrease in filtration efficiency and to prevent pipe bursts or membrane module damage caused by abnormal high pressure. In case of abnormal pressure, it automatically cuts off the power or closes the valve. The flow sensor 17 measures the fluid flow rate in real time and calculates the actual filtration efficiency of the system by combining the pressure data. During water quality testing, the flow data is used to correct the sampling frequency of the sensor. The water quality testing sensor 18 detects parameters such as turbidity, conductivity, and pH value to determine the retention performance of the filter element 7 in real time. It performs multi-parameter testing on the treated water quality and only allows discharge when it meets environmental emission standards to avoid the risk of exceeding standards. Example
[0025] This utility model is as follows Figures 1-3 As shown, the upper mounting bracket 8 has horizontally spaced mounting slots inside, and the upper end of the filter element 7 is snapped into the inside of the mounting slot and fastened. A control valve is movably installed on the outside of the conveying pipe 2 connected to the right side of the filter box 1, and an regulating valve is movably installed on the surface of the discharge pipe 5.
[0026] Using the above technical solution, the upper clip bracket 8 has horizontally spaced mounting slots inside. This design facilitates the standardized and modular installation of the filter element 7. The equally spaced mounting slots not only ensure that the filter element 7 is neatly arranged and improve the utilization rate of the internal space of the filter box 1, but also allow for flexible adaptation to different flow and precision filtration requirements by adjusting the number of filter elements 7. The snap-fit and secure connection between the filter element 7 and the mounting slot makes the installation and disassembly of the filter element 7 convenient, facilitating daily maintenance and replacement. At the same time, the firm connection can prevent the filter element 7 from loosening and shifting during filtration, ensuring the stable operation of the filtration system and preventing bypass leakage of unfiltered media.
[0027] The working principle of this utility model is as follows: The liquid to be filtered enters from the top inlet of the filter box 1 and flows downward under the action of gravity or pressure. When the liquid passes through the filter element 7, the non-woven fabric of the reverse osmosis membrane traps impurities, particles and dissolved substances. The filtered clear liquid flows to the detection box 3 through the delivery pipe 2. The drive motor 13 drives the stirring rod 15 to rotate, so that the detection liquid is evenly mixed. The pressure sensor 16 monitors the pressure of the filtered liquid in real time to determine the filter element blockage status. The flow sensor 17 measures the liquid flow rate to evaluate the filtration efficiency. The water quality detection sensor 18 analyzes parameters such as conductivity and turbidity to determine the filtration effect. When disassembling, pull out the two front and rear plug rods 12, lift the top cover plate 10 upward to release the compression limit of the support spring 9. The support spring 9 drives the upper clip bracket 8 to integrate the top of the filter element 7. Then, the end of the filter element 7 is moved upward from the inside of the positioning seat 6 to complete the replacement.
