Description

Technical Field

[0001] This utility model relates to the field of hollow fiber membrane post-processing technology, and in particular to a continuous cleaning and drying device for hollow fiber membranes. Background Technology

[0002] In traditional hollow fiber membrane production, the washing and drying steps must be performed separately. This process has several significant drawbacks: First, production efficiency is relatively low. The membrane needs to be transferred multiple times to different washing tanks and drying chambers, which is not only cumbersome and time-consuming, but also exposes the hollow fiber membrane surface to mechanical damage during transfer. Furthermore, the washing and drying processes release volatile organic compounds (VOCs), increasing environmental pressure. Second, energy consumption is a significant issue. Because washing and drying are two independent processes, a large amount of heat is lost during drying, resulting in energy waste. In addition, the waste heat generated in the washing process is difficult to effectively recover and utilize, further exacerbating energy consumption.

[0003] Hollow fiber membranes are susceptible to mechanical damage during production. During transfer, they are subjected not only to mechanical friction but also to thermal stress caused by uneven temperature distribution. These factors can lead to structural damage, affecting performance and lifespan. Finally, inconsistent quality within the same batch of products can occur. Differences in the cleaning process due to factors such as personnel, operating conditions, time, and concentration can result in inconsistencies in cleaning residues and performance within the same batch of membrane fibers, impacting the quality of the final product. Therefore, a continuous cleaning and drying device for hollow fiber membranes is needed to address the problems of low efficiency, energy waste, and membrane fiber damage in traditional production processes.

[0004] The patent "A Drying Device for Hollow Fiber Membranes" (Publication No. CN222418387U, hereinafter referred to as Prior Art 1) discloses a continuous fiber coating device. Prior Art 1 includes a drying chamber and a hollow fiber membrane. A feed inlet is located on one side wall of the drying chamber, and a discharge outlet is located on the other side wall. A sealed door is installed on the outer wall. Multiple sets of support rollers are installed inside the chamber. Limiting plates are fixedly connected to the two side walls of the support rollers and connected to the inner wall of the drying chamber via support rods. The hollow fiber membrane is movably wound onto the support rollers. Multiple sets of fans are installed through movable slots to blow air onto the heating plate. Hot air is blown inward from the side wall onto the drying membrane. Rectangular slots are provided with filters to prevent dust from entering the fans.

[0005] Existing technology 1 only focuses on the drying process and fails to solve the problem of low efficiency caused by the separate operation of cleaning and drying in traditional production. Due to the lack of an integrated continuous design of the cleaning and drying mechanisms, hollow fiber membranes still need to be transferred between different equipment, which is cumbersome and time-consuming and can easily cause damage to the membrane fibers.

[0039] Example 1

[0040] Please see Figure 1This utility model provides a continuous cleaning and drying device for hollow fiber membranes. In the traditional hollow fiber membrane production process, the cleaning and drying stages are independent, which has significant drawbacks. First, the repeated transfer of the membrane to different cleaning tanks and drying chambers is not only cumbersome and time-consuming, severely reducing production efficiency, but also causes damage to the membrane surface due to mechanical friction. Furthermore, the erosion by volatile organic compounds (VOCs) during cleaning and drying further exacerbates the risk of membrane surface damage. Second, the independent cleaning and drying processes result in a significant loss of drying heat, and the waste heat generated in the cleaning process cannot be recovered, leading to prominent energy consumption issues. In addition, the hollow fiber membrane 100 is highly susceptible to structural damage during transfer due to mechanical friction or thermal stress, affecting its performance and service life. Finally, even membrane fibers produced in the same batch can exhibit inconsistencies in cleaning residues and performance due to differences in the cleaning process, resulting in inconsistent product quality. These problems collectively restrict the efficiency, energy saving, and product quality stability of hollow fiber membrane production. Therefore, this utility model aims to solve the technical problems in traditional hollow fiber membrane production, such as low production efficiency, serious energy waste, easy damage to membrane fibers, and unstable product quality caused by the separate steps of cleaning and drying.

[0041] In this embodiment, by integrating the cleaning mechanism 300 and the drying mechanism 500 into a continuous design, the membrane fiber transfer process is reduced, avoiding mechanical friction and damage to the membrane fibers from volatile organic compounds. The waste heat from drying is recovered by a thermal circulation mechanism and recycled for the cleaning process, reducing energy consumption. At the same time, through the unique design of the guide roller 410 transmission mechanism, transmission roller 340, and comb, the membrane fibers are prevented from tangling or stacking during transmission, ensuring the integrity of the membrane fiber structure and the stability of its performance, and ensuring the consistency of product quality in the same batch, thereby significantly improving the overall efficiency and product quality of hollow fiber membrane production.

[0042] Further, please see Figure 1The continuous cleaning and drying device in this embodiment includes a cleaning mechanism 300, a drying mechanism 500, and a heat circulation mechanism. The cleaning mechanism 300 has a series-connected cleaning tank for continuously cleaning the hollow fiber membrane 100. The drying mechanism 500 has a drying zone at the top for drying via an infrared heating component and a hot air jet component 511 at the bottom. The drying mechanism 500 dries the cleaned hollow fiber membrane 100. The heat circulation mechanism connects the drying mechanism 500 and the cleaning mechanism 300 via a pipe system 610 and is used to recycle the heat energy of the drying mechanism 500. The cleaning mechanism 300 and the drying mechanism 500 are connected at the top via a guide wheel 410 transmission mechanism. The guide wheel 410 in the transmission mechanism has an axial groove on its surface and is covered with a flexible material layer, and is used to guide the hollow fiber membrane 100 to move continuously in the cleaning mechanism 300, the drying mechanism 500, and the heat circulation mechanism.

[0043] In use, one end of the hollow fiber membrane 100 to be cleaned is mounted on the guide wheel 410 transmission mechanism. The device is then started, and the hollow fiber membrane 100, driven by the guide wheel 410 transmission mechanism, sequentially passes through the cleaning mechanism 300 and the drying mechanism 500 for continuous cleaning and drying. In the cleaning mechanism 300, the hollow fiber membrane 100 passes through multiple cleaning tanks arranged in series, each containing a different cleaning solution, performing progressively deep cleaning of the hollow fiber membrane 100 to effectively remove stains and impurities from the membrane surface. Subsequently, the membrane enters the drying mechanism 500, where it undergoes preliminary drying via an infrared heating component and secondary drying via a hot air jet component 511, ensuring that moisture is completely removed from the surface of the hollow fiber membrane 100.

[0044] Meanwhile, the heat circulation mechanism continuously recovers the waste heat generated by the drying mechanism 500 and transports it to the cleaning mechanism 300 through the pipeline system 610 for heat energy recycling, significantly improving energy utilization efficiency. Throughout the cleaning and drying process, the axial grooves and flexible material layer on the surface of the guide rollers 410 in the guide roller transmission mechanism effectively prevent the hollow fiber membrane 100 from tangling and stacking during transmission, ensuring the integrity of the membrane structure and the stability of its performance. The hollow fiber membrane 100 processed by this continuous cleaning and drying device not only sees a significant increase in production efficiency and a significant reduction in energy consumption, but also effectively controls the risk of surface damage to the membrane fibers, resulting in more stable and consistent product quality within the same batch, meeting the demands for high-efficiency, energy-saving, and high-quality production.

[0045] Further, please see Figure 6The cleaning tank includes a pre-cleaning tank 310, an ultrasonic cleaning tank 320, and a rinsing tank 330 connected in series. The cleaning mechanism 300, as well as the pre-cleaning tank 310, the ultrasonic cleaning tank 320, and the rinsing tank 330, are equipped with several adjustable transmission rollers 340. The hollow fiber membrane 100 is conveyed by the several transmission rollers 340 and operates sequentially in the pre-cleaning tank 310, the ultrasonic cleaning tank 320, and the rinsing tank 330.

[0046] Several adjustable transmission rollers 340 can be set by a pair of cylinders; the pair of cylinders are respectively set at both ends of the adjustable transmission rollers 340; when adjustment is required, the pair of cylinders simultaneously drive the transmission rollers 340 to rise and fall, so as to adapt to hollow fiber membranes 100 of different thicknesses or materials, different cleaning depths or immersion depths, so as to ensure that the hollow fiber membrane 100 can be smoothly transported and fully contacted with the cleaning liquid during the cleaning process.

[0047] An appropriate amount of preliminary cleaning solution is injected into the pre-cleaning tank 310 to remove most of the dirt and loose impurities from the surface of the hollow fiber membrane 100. Subsequently, the hollow fiber membrane 100 enters the ultrasonic cleaning tank 320. The ultrasonic cleaning tank 320 uses an integrated array of transducers to clean the hollow fiber membrane 100. Through the cavitation effect and direct flow of ultrasound, the hollow fiber membrane 100 is deeply cleaned, effectively breaking down and peeling off stubborn stains on the membrane surface. Finally, the hollow fiber membrane 100 enters the rinsing tank 330 and is rinsed with pure water to thoroughly remove residual cleaning solution, ensuring the cleanliness of the hollow fiber membrane 100. The entire cleaning process is highly automated, easy to operate, and greatly improves cleaning efficiency and quality.

[0048] Further, please see Figure 2 and Figure 3 The drying mechanism 500 is provided with a drying chamber 510; the top and bottom of the drying chamber 510 are respectively provided with a first roller 521, a first comb 522, a second roller 525, and a second comb 526; the hollow fiber membrane 100 is cross-conducted in the drying chamber based on the first roller 521 and the second roller 525.

[0049] During operation, the hollow fiber membrane 100 is first fed into the system via the first roller 521 and then conveyed in a cross-flow manner. It passes sequentially through the first comb 522 and the second comb 526 before entering the second roller 525. After this stage, the hollow fiber membrane 100 passes through the second comb 526 and the first comb 522 again before returning to the first roller 521. By repeating this series of processes, the hollow fiber membrane 100 undergoes a thorough drying process. This process continues until the hollow fiber membrane 100 is completely dry and is finally discharged from the system.

[0050] Further, please see Figure 4 and Figure 5 The drying chamber 510 includes a preheating zone, a main drying zone and a slow cooling zone connected together; the hot air jet assembly 511 in the main drying zone is composed of a multi-hole nozzle array, with the nozzles tilted toward the transmission path of the hollow fiber membrane 100.

[0051] During operation, hot air is sprayed at a specific angle onto the hollow fiber membrane 100 through a multi-hole nozzle array, ensuring that the hot air can evenly cover and penetrate the hollow fiber membrane 100, thereby accelerating the drying efficiency. The preheating zone first preheats the hollow fiber membrane 100, preparing it for entry into the main drying zone. The main drying zone is the core of the drying process, where intense hot air thoroughly dries the hollow fiber membrane 100. The slow cooling zone gradually lowers the temperature, preventing the hollow fiber membrane 100 from deforming or developing internal stress due to sudden cooling. This zoned drying design not only improves drying efficiency but also ensures drying quality, resulting in a hollow fiber membrane 100 with excellent drying effect and stable physical properties.

[0052] Furthermore, the heat circulation mechanism connects the cleaning mechanism 300 and the drying mechanism 500 through the pipes 610 in the pipe system 610, and uses the waste heat of the drying mechanism 500 to preheat the water in the cleaning mechanism 300, recover the cleaning tank and the volatile organic solvents in the drying mechanism 500; wherein, the pipe 610 for heat circulation mechanism recovery is located at the bottom of the frame 200.

[0053] The thermal circulation mechanism efficiently guides the waste heat generated by the drying unit 500 to the cleaning unit 300 for preheating the cleaning water. This not only significantly saves energy but also improves the overall thermal efficiency of the equipment. Simultaneously, this mechanism is responsible for recovering volatile organic solvents generated in the cleaning tank and drying unit 500, transporting them to the recycling unit via a dedicated pipeline system 610, thus achieving resource recycling and environmental protection. The recycling pipeline 610, located at the bottom of the frame 200, avoids occupying operating space while ensuring smooth operation of the recycling process. During operation, operators only need to activate the control system of the thermal circulation mechanism to automate the waste heat and solvent recovery processes, greatly simplifying the operation and improving work efficiency.

[0054] Further, please see Figure 1The pipe 610 connecting the cleaning mechanism 300, the drying mechanism 500, and the heat circulation mechanism is located at the bottom of the frame 200; a liquid storage tank 630 and a circulation pump 640 are also located at the bottom of the frame 200. Furthermore, a protective agent impregnation mechanism 400 is included; the protective agent impregnation mechanism 400 is located between the cleaning mechanism 300 and the drying mechanism 500; wherein, the protective agent impregnation mechanism 400 is connected to the cleaning mechanism 300 and the drying mechanism 500 at the top via a guide wheel 410 transmission mechanism.

[0055] Please see Figure 1 The protective agent impregnation mechanism 400 smoothly transports the hollow fiber membrane 100, after being treated by the cleaning mechanism 300, into the protective agent impregnation mechanism 400 via the guide roller 410. Inside the impregnation mechanism, a specific protective agent is evenly sprayed onto the hollow fiber membrane 100. This protective agent forms a protective film on the surface of the hollow fiber membrane 100, effectively preventing corrosion or oxidation of the hollow fiber membrane 100 during subsequent processing or storage. The amount and time of the protective agent spraying can be adjusted by the control system to ensure optimal protection of the hollow fiber membrane 100 surface. After impregnation, the hollow fiber membrane 100 is again transported to the drying mechanism 500 via the guide roller 410 for drying to remove excess protective agent and fix the protective film. The entire process is automated, which not only improves work efficiency but also ensures the consistency and stability of the hollow fiber membrane 100 treatment.

[0056] Further, please see Figure 1 The guide wheel 410 is located on the top of the cleaning mechanism 300, the protective agent impregnation mechanism 400 and the drying mechanism 500; the top of the cleaning mechanism 300, the protective agent impregnation mechanism 400 and the drying mechanism 500 are all provided with a top cover 210; the top cover 210 is also provided with an opening 211 for the hollow fiber membrane 100 to pass through at the position where the guide wheel 410 is located.

[0057] In use, the hollow fiber membrane 100 enters the cleaning mechanism 300 through the guide roller 410 located at the top of the cleaning mechanism 300, and is conveyed and cleaned by the adjustable transfer roller 340 inside the cleaning mechanism 300. A protective agent is then introduced into the impregnation tank of the protective agent impregnation mechanism 400 from the top of the cleaning mechanism 300 for impregnation with protective liquid. After impregnation, it is then introduced into the drying mechanism 500, which dries the hollow fiber membrane 100 in stages. After drying, it is output and stored. During the cleaning and drying operations of the hollow fiber membrane 100, the heat circulation mechanism connects the cleaning mechanism 300 and the drying mechanism 500 through pipes 610 in the pipe system 610. It utilizes the residual heat of the drying mechanism 500 to preheat the water in the cleaning mechanism 300, the recovery cleaning tank, and the volatile organic solvents in the drying mechanism 500; and sends the recovered organic solvents to the recovery tank 620.

[0058] Furthermore, the first comb 522 includes a guide roller 523 and comb teeth 524 arranged at equal intervals along the circumference of the guide roller 523. The ends of the comb teeth 524 are arc-shaped, used to separate and guide the hollow fiber membrane 100 filaments to be evenly distributed, preventing the membrane filaments from tangling or stacking. The first comb 522 and the second comb 526 have the same structural configuration. In use, after being processed by the cleaning mechanism 300, the hollow fiber membrane 100 enters the protective agent impregnation mechanism 400 through the synergistic action of the guide roller 523 and the comb teeth 524. The rotation of the guide roller 523 drives the hollow fiber membrane 100 to move forward smoothly, while the equally spaced comb teeth 524 effectively separate and guide the hollow fiber membrane 100 filaments, ensuring that they are evenly distributed in the impregnation tank. This design not only avoids the problem of membrane filaments tangling or stacking during the impregnation process, but also improves the impregnation efficiency, ensuring that each hollow fiber membrane 100 filament can fully contact the protective liquid. Meanwhile, the identical structural design of the first comb 522 and the second comb 526 ensures the continuity and stability of the entire impregnation process, further improving the reliability and durability of the equipment.

[0059] In this embodiment, the cleaning mechanism 300 and the drying mechanism 500 are spatially compactly arranged, integrating the cleaning tank and the drying chamber into the same equipment frame. Simultaneously, a transmission system consisting of a guide wheel 410 transmission mechanism, a transmission roller 340, and a comb is used to achieve a smooth transition and orderly transport of the hollow fiber membrane 100 between the two mechanisms, avoiding damage during the transfer of the hollow fiber membrane 100. Furthermore, the process parameters for cleaning and drying are synergistically optimized and controlled. Based on the membrane material characteristics, parameters such as the composition, temperature, flow rate, and time of the cleaning solution, as well as the drying temperature, wind speed, and duration, are precisely set to ensure that the cleaned membrane fibers can quickly enter the drying process under suitable conditions. This achieves an integrated and continuous design of the cleaning and drying mechanisms, significantly improving production efficiency and product quality.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
