Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane production technology, specifically to a device for detecting the adsorption of impurities on the surface of a reverse osmosis membrane nonwoven fabric with self-cleaning function. Background Technology

[0002] Reverse osmosis membrane is an artificial semi-permeable membrane with certain characteristics, made by simulating biological semi-permeable membranes. It is the core component of reverse osmosis technology. The membrane pore size of reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter and other substances from water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.

[0003] In the production process of reverse osmosis membranes, non-woven fabrics play an important role as a support layer. However, the surface of non-woven fabrics may adsorb various impurities, such as dust and fiber debris. These impurities can affect the performance and quality of reverse osmosis membranes. Currently, the detection of impurities on the surface of non-woven fabrics mainly relies on manual visual inspection or simple mechanical inspection. This method has low detection efficiency, poor accuracy, and cannot effectively self-clean the detection device, leading to a decrease in the reliability of the detection results.

[0013] 2. This utility model utilizes a pull-out wastewater collection box installed within the trough, allowing for the centralized collection of wastewater generated during the cleaning of the electrostatic adsorption roller. Workers can directly pull out the collection box for cleaning, eliminating the need for cumbersome drainage pipe installations and complex drainage operations. This simplifies wastewater treatment and improves equipment maintenance convenience. The pull-out installation facilitates the replacement and cleaning of the wastewater collection box.

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.

[0019] 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

[0020] Please see Figure 1 As shown, this utility model provides a reverse osmosis membrane nonwoven fabric surface impurity adsorption detection device with self-cleaning function, including a detection box 1. Drive rollers 2 are rotatably installed on both sides of the inner cavity of the detection box 1. An electrostatic adsorption roller 3 is rotatably installed above the space between the two drive rollers 2. A drive motor 4 is fixedly installed at the rear end of the electrostatic adsorption roller 3. Cleaning pipes 6 are symmetrically installed above both sides of the electrostatic adsorption roller 3. A cleaning nozzle 7 is connected to one side of the cleaning pipe 6 corresponding to the electrostatic adsorption roller 3. A water pump 8 is connected to the rear side of the detection box 1 via a pipe on the right side of the cleaning pipe 6. A water tank 9 is connected to the inlet pipe of the water pump 8. An industrial camera 17 is fixedly installed on the right side of the inner cavity of the detection box 1. A controller 18 and a display screen 19 are respectively installed on the right side of the front of the detection box 1 and the front end of the right side. The industrial camera 17 is electrically connected to the display screen 19 and the controller 18.

[0021] This technical solution integrates impurity adsorption, cleaning, and detection functions into the detection box 1. One device can complete the entire process from impurity adsorption and cleaning of the electrostatic adsorption roller 3 to surface impurity detection. Compared with the traditional multi-device step-by-step processing method, it greatly saves space and production costs, and improves production efficiency. The cleaning pipe 6 works with the water pump 8 to automatically spray water for cleaning. The industrial camera 17, controller 18, and display screen 19 work together to realize automatic detection and result display, reducing manual intervention, lowering labor costs, and avoiding errors caused by manual operation, thus ensuring the accuracy and stability of the detection results. The industrial camera 17 captures images of the nonwoven fabric surface in real time, the controller 18 analyzes the images, and the detection results are directly displayed on the display screen 19. Operators can quickly and intuitively understand the impurity situation on the nonwoven fabric surface, adjust the production process in a timely manner, and ensure product quality. Example

[0022] Based on Embodiment 1, this utility model is as follows: Figure 3 As shown, a positioning frame 5 is snapped onto the top of the cleaning tube 6, and the top of the positioning frame 5 is connected to the top of the inner cavity of the detection box 1 via a connecting vertical plate; a bearing frame 10 is sleeved on the lower end of the water tank 9, and the front end of the bearing frame 10 is connected to the back of the detection box 1.

[0023] Adopting such Figure 1 The technical solution shown uses a positioning bracket 5 to securely fix the cleaning tube 6 in place. When cleaning the electrostatic adsorption roller 3, the cleaning nozzle 7 can be stably aligned with the surface of the adsorption roller, ensuring uniform spraying of the cleaning solution and effectively removing impurities from the adsorption roller. This avoids incomplete cleaning due to shaking or shifting of the cleaning tube 6. The snap-fit ​​installation method facilitates quick installation and removal of the cleaning tube 6. When the cleaning tube 6 becomes clogged or damaged, staff can quickly remove it for cleaning or replacement without complicated tools or cumbersome procedures, thus improving equipment maintenance efficiency and reducing downtime.

[0024] Secondly, in the technical solution, a sealing baffle 11 is movably installed on the front of the detection box 1 and at the end position corresponding to the electrostatic adsorption roller 3. Guide slide plates 13 are fixedly installed on both the upper and lower sides of the sealing baffle 11. A transverse guide rod 12 is embedded on the back of the guide slide plate 13. The back of the transverse guide rod 12 is connected to the front of the detection box 1. A limit plate 14 is fixedly installed on the right side of the sealing baffle 11 and on the front of the detection box 1.

[0025] Its adoption is as follows Figure 1The technical solution shown features a sealing baffle 11 that can be easily pushed and pulled in the lateral direction through a sliding connection design between the guide slide plate 13 and the transverse guide rod 12. When the electrostatic adsorption roller 3 needs to be inspected, replaced, or cleaned, the operator can directly slide the baffle open to expose the internal structure without using tools, which greatly shortens the maintenance time. The setting of the limiting plate 14 ensures that the baffle will not leave the track during the sliding process, and at the same time limits the maximum opening position to prevent the baffle from accidentally slipping or shifting, thereby improving operational safety. Example

[0026] This utility model is as follows Figures 1-3 As shown, a receiving groove 15 is provided at the bottom of the front of the detection box 1, and a wastewater collection box 16 is pulled out and installed inside the receiving groove 15 and at the bottom of the inner cavity of the detection box 1; the bottom of the electrostatic adsorption roller 3 is at the same level as the top of the transmission roller 2, and a conveying groove is provided on both sides of the detection box 1.

[0027] By adopting the above technical solution, the wastewater collection box 16 installed in the receiving tank 15 in a pull-out manner can collect the wastewater generated by cleaning the electrostatic adsorption roller 3. The staff can directly pull out the collection box for cleaning, without the need for cumbersome drainage pipe settings and complicated drainage operations, making wastewater treatment easier and improving the convenience of equipment maintenance. The pull-out installation method facilitates the replacement and cleaning of the wastewater collection box 16. When the collection box is damaged or needs to be thoroughly cleaned, it can be quickly disassembled and replaced, reducing equipment downtime and ensuring the continuity of testing work. The bottom of the electrostatic adsorption roller 3 and the top of the transmission roller 2 are on the same horizontal plane, which allows the non-woven fabric to remain stable during the conveying process, avoiding problems such as wrinkles and jamming caused by height differences, ensuring that the non-woven fabric can pass through the testing area smoothly, improving testing efficiency and testing quality.

[0028] The working principle of this utility model is as follows: the drive motor 4 drives the electrostatic adsorption roller 3 to rotate in the opposite direction to the non-woven fabric conveying direction. The electrostatic field generated on its surface adsorbs dust, fibers and other impurities on the surface of the non-woven fabric. When the adsorbed non-woven fabric passes under the industrial camera 17, the camera takes a picture of the surface at a set frequency and transmits the data to the controller 18. The controller 18 analyzes the impurity residue through the image recognition algorithm, calculates parameters such as the number and area of ​​impurities, and finally displays the detection results in real time on the display screen 19. When the industrial camera 17 detects that too many impurities have accumulated on the surface of the adsorption roller, the water pump 8 is automatically started. The water pump 8 draws cleaning liquid from the water tank 9 and transports it through the pipeline to the cleaning pipe 6. Then, it is evenly sprayed on the surface of the electrostatic adsorption roller 3 in a fan-shaped spray form through the cleaning nozzle 7. The wastewater generated by cleaning flows along the surface of the adsorption roller into the wastewater collection tank 16 at the bottom of the detection box 1.

[0029] When deep maintenance of the electrostatic adsorption roller 3 is required, the operator can slide the sealing baffle 11 along the transverse guide rod 12 to open the inspection port and remove and clean the internal electrostatic adsorption roller 3.
