Description

Technical Field

[0001] This utility model relates to the technical field of combined membrane separation experimental devices, specifically a combined membrane separation experimental device. Background Technology

[0002] The combined membrane separation experimental device is an experimental equipment used for membrane separation technology research and teaching. This device integrates multiple membrane separation components, such as ultrafiltration, nanofiltration and reverse osmosis. Different membrane components can be selected for individual or combined use according to experimental needs. These three membrane separation methods all use pressure difference as the driving force and are suitable for the separation of substances with different molecular weights. By using the combined membrane separation experimental device, students and researchers can gain an in-depth understanding of the principles and applications of membrane separation technology, master experimental operation skills, and provide a theoretical and practical foundation for practical applications.

[0003] Common combined membrane separation experimental devices are usually fixed in use, which makes it inconvenient to clean their interiors. During the membrane separation process, the membrane surface and membrane pores are easily adsorbed or blocked by contaminants. These contaminants will gradually accumulate, leading to increased membrane fouling. Membrane fouling will cause a significant reduction in membrane flux, affecting separation efficiency and product recovery rate, and bringing certain adverse effects to the user experience. To address this, we propose a combined membrane separation experimental device. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides a combined membrane separation experimental device with advantages such as improved cleaning efficiency and ease of maintenance and inspection. Through a movable sealing cover mechanism, a moving block is fitted onto the outer wall of the adjusting rod via a through-hole adjusting block, positioning the cover plate inside the cover plate limiting groove. A supporting plate inside the cover plate limiting groove provides stability. A control motor inside the control groove drives the adjusting rod to rotate inside the adjusting groove, causing the moving block to move on the outer wall of the adjusting rod, thereby moving the cover plate inside the cover plate limiting groove. An upper sealing connecting plate at the top of the cover plate enhances sealing. Direct access to the device's interior is possible without disassembling other components, saving time and labor. Regular cleaning of the device's interior effectively prevents the accumulation of dirt, bacteria, and other contaminants, ensuring the accuracy and reliability of experimental results.

[0025] Working Principle: A combined membrane separation experimental device includes a main body 1, a feed pipe 2, a movable sealing cover mechanism 3, a display screen 4, an ultrafiltration membrane 5, a nanofiltration membrane 6, and a reverse osmosis membrane 7. In use, the liquid to be treated is poured into the main body 1 through the feed pipe 2. The liquid first passes through the ultrafiltration membrane 5, which retains large molecules such as proteins and colloids. Then, the liquid in the ultrafiltration membrane 5 enters the nanofiltration membrane 6, which retains smaller molecules such as low-molecular-weight organic matter and some ions. Finally, the liquid in nanofiltration membrane 6 enters reverse osmosis membrane 7, where almost all dissolved substances are retained, producing pure water. During the experiment, the state of the feed liquid, such as pressure, flow rate, conductivity, and temperature, is monitored in real time via display screen 4. The liquids permeating through ultrafiltration membrane 5, nanofiltration membrane 6, and reverse osmosis membrane 7 are collected as permeate, while the retained liquid forms concentrate. Samples are taken from the permeate outlets of ultrafiltration membrane 5, nanofiltration membrane 6, and reverse osmosis membrane 7 for analysis to evaluate the membranes. The separation effect is achieved through the movable sealing cover mechanism 3. The moving block 309 is sleeved on the outer wall of the adjusting rod 306 through the adjusting block 310, so that the cover 307 is positioned inside the cover plate limiting groove 301. The supporting plate 302 provides support and stability inside the cover plate limiting groove 301. The control motor 305 inside the control groove 304 can drive the adjusting rod 306 to rotate inside the adjusting groove 303, so that the moving block 309 moves on the outer wall of the adjusting rod 306, thereby driving the cover 307 to move inside the cover plate limiting groove 301. The upper sealing connecting plate 311 at the upper end of the cover 307 can enhance the sealing performance. The equipment interior can be directly accessed without disassembling other parts, saving time and labor. Regular cleaning of the equipment interior can effectively prevent the accumulation of dirt, bacteria and other contaminants, ensuring the accuracy and reliability of experimental results. Keeping the equipment interior clean helps reduce wear and contamination of membrane modules and other components, thereby extending the service life of the equipment.
