Description

Technical Field

[0001] This utility model relates to the field of nanofiber production technology, specifically a self-cleaning nanofiber production pilot machine. Background Technology

[0002] Nanofibers, due to their unique physical and chemical properties, such as high specific surface area and excellent porosity, have found wide applications in numerous fields, including filtration materials, biomedicine, and energy storage. Pilot-scale equipment plays a crucial role in the production of nanofibers, serving as a bridge between laboratory research and large-scale industrial production.

[0003] In electrospinning technology, a common process in nanofiber production, the emitter electrode is a key component. During the spinning process, the surface of the emitter electrode easily adsorbs solutes, impurities, and fiber debris from the spinning solution. Over time, these deposits affect the electric field distribution of the emitter electrode, leading to uneven electric field distribution during spinning, which in turn affects the diameter uniformity, morphology, and yield of the nanofibers. Therefore, cleaning the emitter electrode is particularly important.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] In the existing technology, most pilot machines for nanofiber production lack effective cleaning measures for the emitting electrodes. They usually require manual disassembly of the emitting electrodes for cleaning, which is not only cumbersome and time-consuming, but also prone to damaging the emitting electrodes during disassembly and installation, affecting the normal operation of the equipment. Utility Model Content

[0006] The purpose of this invention is to provide a self-cleaning pilot-scale machine for nanofiber production to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning nanofiber production pilot machine, comprising:

[0008] Pilot-scale machine main body;

[0009] The spinning mechanism is installed inside the main body of the pilot plant for cleaning the electrodes, and includes a protective cover fixedly installed inside the main body of the pilot plant. On both sides of the protective cover, there are electrode tension adjusting seats for adjusting the tension of the electrodes. The top of the electrode tension adjusting seat is provided with an emission electrode.

[0010] The top of the shield is provided with a cleaning component for cleaning the emitting electrode.

[0011] Preferably, the cleaning assembly includes two support plates disposed on both sides of the protective cover, a fixing plate is fixedly installed on the top between the two support plates, and a storage tank for storing cleaning fluid is slidably installed on the top of each adjacent side of the two support plates.

[0012] Hydraulic rods are fixedly installed on both sides of the top of the fixed plate, and the telescopic ends of the two hydraulic rods are fixedly connected to the top of the two liquid storage tanks. A partition plate is fixedly installed inside the liquid storage tank, and the liquid storage tank is separated into a water storage chamber and a liquid storage chamber by the partition plate. Pressure valve pipes are provided on both sides of the inner wall of the partition plate, and the two pressure valve pipes are respectively connected to the water storage chamber and the liquid storage chamber. A horizontal pipe is installed at the bottom between the two liquid storage tanks, and a cleaning block is connected to the adjacent end of the two horizontal pipes.

[0013] Preferably, a cleaning tube is fixedly installed inside the cleaning block, and an immersion core is fixedly installed inside the cleaning tube. The immersion core is made of a sponge component for cleaning the emitting electrode.

[0014] Preferably, an air pump is fixedly installed on the top of the fixed plate, the air pump is connected to a three-way pipe at its outlet end, both ends of the three-way pipe are connected to air outlet pipes, and the end of the air outlet pipe away from the three-way pipe passes through the fixed plate and extends to the bottom of the fixed plate.

[0015] The top of the liquid storage tank is provided with an H-shaped pipe, which runs through the liquid storage tank and is connected to the liquid storage chamber and the water storage chamber. A flexible hose connects the H-shaped pipe to the air outlet pipe.

[0016] Preferably, a miscellaneous storage tank is fixedly installed on the top between the two liquid storage tanks, the air inlet end of the air pump is connected to an air inlet pipe, the end of the air inlet pipe away from the liquid storage tank is connected to the top of the miscellaneous storage tank, and a vertical pipe connects the cleaning block and the miscellaneous storage tank.

[0017] Preferably, slide rails are fixedly installed on the adjacent sides of the two support plates, and slide blocks are fixedly installed on the opposite sides of the two liquid storage tanks, with the liquid storage tanks slidably connected to the slide rails via the slide blocks.

[0018] Preferably, electric slide rails are installed on both sides of the bottom of the cover, and a sliding plate is slidably installed on the surface of each of the two electric slide rails. The top of the sliding plate is fixedly connected to the bottom of the support plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. Utilizing the spinning mechanism, when there are too many impurities on the surface of the emitting electrode, the hydraulic rod drives the liquid storage tank and the cleaning block inside it to descend synchronously and fit onto the surface of the emitting electrode. At this time, the air pump pressurizes the water storage chamber and the liquid storage chamber through the air outlet pipe, so that the water in the water storage chamber and the cleaning liquid in the liquid storage chamber are injected into the inside of the liquid storage tank through the pressure valve pipe, so that the water and the cleaning liquid come into contact and mix. And through the connection between the horizontal pipe and the cleaning block, the cleaning water is injected into the inside of the impregnation core, thereby cleaning the impurities on the surface of the emitting electrode. This avoids damage to the emitting electrode caused by manual disassembly for cleaning, which would affect the normal operation of the equipment.

[0021] 2. When the air pump is working, the air inlet pipe connects to the storage tank to create negative pressure inside the storage tank. The vertical pipe connects to the cleaning block to draw out impurities from the surface of the emitting electrode. This prevents impurities from being re-adsorbed onto the surface of the emitting electrode while the immersion core cleans it, thus avoiding any impact on the cleaning effect.

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.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a self-cleaning nanofiber production pilot machine, comprising:

[0029] Pilot-scale machine main body 1;

[0030] The spinning mechanism 2 is installed inside the pilot machine body 1 for cleaning the electrodes, and includes a protective cover 21 fixedly installed inside the pilot machine body 1. Both sides of the protective cover 21 are equipped with electrode tension adjustment seats 22 for adjusting the tension of the electrodes, and the top of the electrode tension adjustment seat 22 is provided with an emission electrode 23.

[0031] A cleaning component 24 is provided on the top of the shield 21 for cleaning the emitting electrode 23.

[0032] Reference Figure 2 , Figure 3 as well as Figure 4 As shown, the cleaning assembly 24 includes two support plates 241 disposed on both sides of the cover 21, a fixing plate 242 is fixedly installed on the top between the two support plates 241, and a storage tank 243 for storing cleaning fluid is slidably installed on the top of each adjacent side of the two support plates 241.

[0033] Hydraulic rods 244 are fixedly installed on both sides of the top of the fixed plate 242, and the telescopic ends of the two hydraulic rods 244 are fixedly connected to the top of the two liquid storage tanks 243. A partition plate 2413 is fixedly installed inside the liquid storage tank 243, which separates the water storage chamber 245 and the liquid storage chamber 246. Pressure valve pipes 247 are provided on both sides of the inner wall of the partition plate 2413, and the two pressure valve pipes 247 are respectively connected to the water storage chamber 245 and the liquid storage chamber 246. A horizontal pipe 248 is installed at the bottom between the two liquid storage tanks 243, and the two horizontal pipes 248 are adjacent to each other. One end of each is connected to a cleaning block 249; a cleaning tube 2401 is fixedly installed inside the cleaning block 249, and a wetting core 2402 is fixedly installed inside the cleaning tube 2401. The wetting core 2402 is made of sponge and is used to clean the emitting electrode 23; an air pump 2403 is fixedly installed on the top of the fixing plate 242, and a three-way pipe 2404 is connected to the air outlet end of the air pump 2403. Both ends of the three-way pipe 2404 are connected to air outlet pipes 2405, and the end of the air outlet pipe 2405 away from the three-way pipe 2404 passes through the fixing plate 242 and extends to the bottom of the fixing plate 242.

[0034] An h-shaped pipe 2406 is provided on the top of the liquid storage tank 243, and the h-shaped pipe 2406 passes through the liquid storage tank 243 and is connected to the liquid storage chamber 246 and the water storage chamber 245. A flexible hose 2407 is connected between the h-shaped pipe 2406 and the vent pipe 2405.

[0035] In this embodiment, when there are too many impurities on the surface of the emitting electrode 23, the hydraulic rod 244 drives the liquid storage tank 243 and the cleaning block 249 inside it to descend synchronously and be fitted onto the surface of the emitting electrode 23. At this time, the air pump 2403 pressurizes the water storage chamber 245 and the liquid storage chamber 246 through the air outlet pipe 2405, so that the water inside the water storage chamber 245 and the cleaning liquid inside the liquid storage chamber 246 are injected into the interior of the liquid storage tank 243 through the pressure valve pipe 247, so that the water and the cleaning liquid come into contact and mix. And through the connection between the horizontal pipe 248 and the cleaning block 249, the cleaning water is injected into the interior of the immersion core 2402, thereby cleaning the impurities on the surface of the emitting electrode 23. This avoids the situation where the emitting electrode 23 is damaged when it is manually disassembled for cleaning, which would affect the normal operation of the equipment.

[0036] Reference Figure 3 as well as Figure 4 As shown, a miscellaneous storage tank 2408 is fixedly installed on the top between the two liquid storage tanks 243. The air inlet end of the air pump 2403 is connected to an air inlet pipe 2409. The end of the air inlet pipe 2409 away from the liquid storage tank 243 is connected to the top of the miscellaneous storage tank 2408. A vertical pipe 2410 is connected between the cleaning block 249 and the miscellaneous storage tank 2408.

[0037] In this embodiment, the connection between the air inlet pipe 2409 and the storage box 2408 creates a negative pressure inside the storage box 2408, and the connection between the vertical pipe 2410 and the cleaning block 249 absorbs impurities from the surface of the emitting electrode 23. This prevents impurities from being re-adsorbed onto the surface of the emitting electrode 23 and affecting the cleaning effect while the immersion core 2402 cleans the emitting electrode 23.

[0038] Reference Figure 3 as well as Figure 4 As shown, slide rails 2411 are fixedly installed on the adjacent side of the two support plates 241, and slide blocks 2412 are fixedly installed on the opposite side of the two liquid storage tanks 243. The liquid storage tanks 243 are slidably connected to the slide rails 2411 through the slide blocks 2412.

[0039] In this embodiment, the reservoir 243 can maintain its stability when it descends, avoiding scratches on the emitting electrode 23 and preventing damage to the emitting electrode 23.

[0040] Reference Figure 1 As shown, electric slide rails 25 are installed on both sides of the bottom of the cover 21, and slide plates 26 are slidably installed on the surface of the two electric slide rails 25. The top of the slide plate 26 is fixedly connected to the bottom of the support plate 241.

[0041] In this embodiment, the cleaning component 24 can be moved on top of the cover 21 to facilitate cleaning of different positions of the emitting electrode 23.

[0042] Working principle: When there are too many impurities on the surface of the emitting electrode 23, the hydraulic rod 244 drives the liquid storage tank 243 and the cleaning block 249 inside it to descend synchronously and be fitted onto the surface of the emitting electrode 23. At this time, the air pump 2403 pressurizes the water storage chamber 245 and the liquid storage chamber 246 through the air outlet pipe 2405, so that the water in the water storage chamber 245 and the cleaning liquid in the liquid storage chamber 246 are injected into the interior of the liquid storage tank 243 through the pressure valve pipe 247, so that the water and the cleaning liquid come into contact and mix. And through the horizontal pipe 248 and the connection with the cleaning block 249, the cleaning water is injected into the interior of the immersion core 2402, thereby cleaning the impurities on the surface of the emitting electrode 23.

[0043] During operation, the air pump 2403 creates negative pressure inside the storage tank 2408 by connecting the air inlet pipe 2409 to the storage tank 2408, and draws out impurities from the surface of the emitting electrode 23 by connecting the vertical pipe 2410 to the cleaning block 249. This prevents impurities from being re-adsorbed onto the surface of the emitting electrode 23 while the wetting core 2402 cleans the emitting electrode 23.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
