Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, and in particular to a high-speed thermally induced phase separation method for drying and pretreatment equipment of microporous membranes. Background Technology

[0002] High-speed thermal phase separation is one of the mainstream processes for preparing microporous membranes. As membrane production lines continue to develop towards higher speed and continuous operation, pretreatment is required after the membrane extraction process for drying to improve efficiency.

[0003] After the diaphragm extraction stage, the liquid film of extractant adhering to its surface is quite thick. Furthermore, to reduce the transport path and improve processing efficiency, the vertical transport stroke of the diaphragm is shortened, resulting in insufficient time for the liquid film to flow back downwards under its own weight. This causes a large amount of extractant to directly enter the subsequent drying stage with the diaphragm, significantly increasing the operating load of the drying system, increasing drying energy consumption, and significantly increasing the amount of volatile extractant discharged, thus increasing production costs and environmental protection pressure. Simultaneously, impurities accumulated inside the extraction stage easily adhere to the membrane surface along with the old extractant. After the extractant evaporates and dries, these impurities remain on the diaphragm surface, forming appearance defects that directly affect the quality and performance of the finished diaphragm product.

[0004] Therefore, a high-speed thermally induced phase separation method for microporous membrane drying pretreatment equipment is provided to address the above problems. Utility Model Content

[0032] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments described herein.

[0033] like Figures 1-7 As shown, the high-speed thermally induced phase separation method microporous membrane drying pretreatment equipment includes a tank 1; a cleaning mechanism 5 is provided on the top of the tank 1, and two carriers 11 are provided above the cleaning mechanism 5. Each of the two carriers 11 is equipped with a scraper roller 4 through a disassembly and assembly mechanism 13.

[0034] It also includes a conveying mechanism for conveying the diaphragm 10 after the extraction section, so that the diaphragm 10 passes sequentially through the tank 1, the cleaning mechanism 5 and the two scraping rollers 4; the diaphragm 10 located at the cleaning mechanism 5 and the scraping rollers 4 is arranged vertically.

[0035] The carrier 11 is connected to an adjustment mechanism 3; the adjustment mechanism 3 is used to adjust the two scraping rollers 4 to be tangent to or separate from the two sides of the diaphragm 10 respectively.

[0036] After being processed by the extraction section, the diaphragm 10 is output from the tank 1 and then enters the cleaning mechanism 5. The cleaning mechanism 5 sprays a new, impurity-free extractant onto the diaphragm 10, and the old extractant adhering to the surface of the diaphragm 10 is washed away by the jet flushing action, thereby cleaning the diaphragm 10.

[0037] After the diaphragm 10 is cleaned, it continues to be conveyed to the scraper roller 4. The two scraper rollers 4 are tangentially attached to both sides of the diaphragm 10 to scrape off the fresh extract liquid remaining on the surface of the diaphragm 10, thereby reducing the amount of extractant adhering to the surface of the diaphragm 10 and avoiding increasing the load of the subsequent drying process and the amount of volatile extractant to be processed.

[0038] The above-mentioned cleaning and extract scraping process can provide effective pretreatment for the subsequent drying process of the diaphragm 10.

[0039] like Figures 1-3 As shown, the cleaning mechanism 5 includes an inlet pipe 501 and a three-way pipe 502 fixed to the outer wall of the tank 1; the top end of the inlet pipe 501 is fixedly connected to one end of the three-way pipe 502, and the other two ends of the three-way pipe 502 are fixedly connected to a straight pipe 503. An end cap 504 is fixed to the end of the straight pipe 503 away from the three-way pipe 502, and a plurality of nozzles 505 facing the diaphragm 10 are installed at equal intervals along the length of the straight pipe 503.

[0040] The bottom end of the inlet pipe 501 is connected to the pump body, which is connected to the container storing the new extractant free of impurities.

[0041] During the cleaning process, the pump connected to the new extractant storage container is started, pressurizing and delivering the new, impurity-free extractant to the inlet pipe 501. The extractant flows upward through the inlet pipe 501 into the three-way pipe 502, and after being split by the three-way pipe 502, it enters two straight pipes 503 respectively. Then, it is sprayed out from multiple equally spaced nozzles 505 along the length of the straight pipes 503, forming a continuous jet to flush the diaphragm 10, thus completing the cleaning operation of the diaphragm 10.

[0042] like Figures 1-2 As shown, the conveying mechanism includes a first conveying roller 7, a second conveying roller 8, and a third conveying roller 9; a second support 6 is fixed on the outer wall of the tank 1, the first conveying roller 7 is rotatably mounted on the second support 6, and the second conveying roller 8 and the third conveying roller 9 are both rotatably mounted inside the tank 1; the diaphragm 10 passes around the third conveying roller 9, the second conveying roller 8, and the first conveying roller 7 in sequence.

[0043] like Figure 2 As shown, the cleaning mechanism 5 and the scraper roller 4 are located between the first conveying roller 7 and the second conveying roller 8, and the diaphragm 10 that passes over the first conveying roller 7 and the second conveying roller 8 is in a vertical state.

[0044] At least one of the first conveying roller 7, the second conveying roller 8, and the third conveying roller 9 is connected to an external drive motor, which provides rotational driving force.

[0045] During operation, driven by the drive motor, the first conveying roller 7, the second conveying roller 8, and the third conveying roller 9 rotate, forming traction and guidance for the diaphragm 10. After being guided and conveyed in the tank 1 by the third conveying roller 9 and the second conveying roller 8, the diaphragm 10 passes through the cleaning mechanism 5 and the scraper roller 4, and is then guided and conveyed by the first conveying roller 7, so that the diaphragm 10 is conveyed into the external drying equipment.

[0046] like Figure 1 , Figure 4 as well as Figure 5 As shown, a first upright frame 2 is fixed to the top of the tank 1, and the adjustment mechanism 3 is fixedly installed on the first upright frame 2. The adjustment mechanism 3 includes a back plate 301 fixed to the first upright frame 2 and a movable seat 310. A bracket 307 is fixed to one side of the bottom of the back plate 301. A stud 308 is rotatably installed on the bracket 307, and a slide rail 309 is fixed on the bracket 307. One end of the stud 308 is connected to a driving part. A screw hole 3101 is provided on the movable seat 310. The movable seat 310 is threadedly connected to the stud 308 through the screw hole 3101. A sliding groove 3102 is provided at the bottom of the movable seat 310. The movable seat 310 is slidably connected to the slide rail 309 through the sliding groove 3102. A connecting seat 12 is fixed to the top of the movable seat 310. One side of the connecting seat 12 is fixed to the carrier frame 11. The easy-to-disassemble mechanism 13 is installed on the carrier frame 11 and the connecting seat 12.

[0047] The drive unit includes a first rotating shaft 302 and a second rotating shaft 305 rotatably mounted on a back plate 301. One end of the second rotating shaft 305 is fixed to one end of a stud 308, and a worm gear 306 is fixedly sleeved on the second rotating shaft 305. The worm gear 306 meshes with a worm 304, and the worm 304 is rotatably mounted on the back plate 301. The top end of the worm 304 is fixed to the bottom end of the first rotating shaft 302, and a handwheel 303 is fixed to the top end of the first rotating shaft 302.

[0048] The working process of the adjustment mechanism 3 is as follows: When adjusting the position of the scraper roller 4, the handwheel 303 is turned, which drives the first rotating shaft 302 to rotate. The first rotating shaft 302 drives the worm gear 304 to rotate synchronously. The worm gear 304 meshes with the worm wheel 306, which drives the worm wheel 306 and the second rotating shaft 305 to rotate, thereby driving the stud 308 to rotate around its own axis. During the rotation, the stud 308 drives the movable seat 310 to slide linearly along the slide rail 309 through the threaded engagement. The movable seat 310 drives the carrier 11 to move synchronously through the top connecting seat 12, thereby driving the scraper roller 4 on the carrier 11 to achieve displacement, and finally completing the adhesion or separation of the two scraper rollers 4 with the two sides of the diaphragm 10.

[0049] When scraping the liquid from the diaphragm 10, the scraper roller 4 is brought into contact with the diaphragm 10; when inserting the membrane, the two scraper rollers 4 are moved outward to leave space for inserting the membrane.

[0050] like Figures 4-7 As shown, the easy-to-assemble / disassemble mechanism 13 includes a compression block 1302 disposed at the center of the bottom of the carrier 11; a pressure-bearing column 1301 is fixed to one side of the compression block 1302, the pressure-bearing column 1301 is slidably mounted on the movable seat 310, and the pressure-bearing column 1301 is elastically connected to the connecting seat 12; the compression block 1302 has an isosceles trapezoidal structure, and its width decreases sequentially along the direction away from the pressure-bearing column 1301; a sliding sleeve 13 is slidably mounted on each side of the compression block 1302. 06. A movable frame 1305 is fixed on one side of the sliding sleeve 1306. The movable frame 1305 is slidably sleeved with the guide sleeve 1307 fixed at the bottom of the carrier frame 11. The movable frame 1305 is elastically connected to the carrier frame 11. A round insert post 1311 is fixed on the top side of the movable frame 1305. The round insert post 1311 is slidably sleeved with the guide rings 1101 fixed on both sides of the carrier frame 11. A round insertion hole 401 is opened at the center of both ends of the scraper roller 4. The round insertion hole 401 is used for inserting the round insert post 1311.

[0051] like Figure 5 As shown, the pressure-bearing column 1301 is slidably engaged with the slot on the movable seat 310, and a guide block 1303 is fixed on the top of the pressure-bearing column 1301. The guide block 1303 is slidably connected with the guide groove 1201 on the connecting seat 12. A first spring 1304 is provided in the guide groove 1201, and the guide block 1303 is elastically connected to the groove wall on one side of the guide groove 1201 through the first spring 1304.

[0052] The sliding of the slot and guide block 1303 and guide groove 1201 provides guidance for the movement of the pressure column 1301 along its length. The two ends of the first spring 1304 are fixed to the side wall of the guide block 1303 and the guide groove 1201 respectively, realizing the elastic connection between the guide block 1303 and the side wall of the guide groove 1201.

[0053] like Figures 6-7 As shown, a fixing block 1308 is fixed on the movable frame 1305, and a second spring 1309 is provided between the fixing block 1308 and the guide sleeve 1307. The two ends of the second spring 1309 are fixed to the fixing block 1308 and the side wall of the guide sleeve 1307, respectively. Through the above design, an elastic connection between the movable frame 1305 and the carrier frame 11 is achieved.

[0054] like Figures 6-7As shown, a magnetic block 1310 is fixed to the bottom of the carrier 11. The fixing block 1308 is an iron block, and the magnetic block 1310 is used to magnetically limit the fixing block 1308.

[0055] like Figure 2 , Figure 4 as well as Figure 5 As shown, a pressure seat 14 is fixed on the back plate 301, and the pressure seat 14 faces the end of the pressure column 1301 away from the extrusion block 1302.

[0056] When the scraper roller 4 and the diaphragm 10 are in normal working contact, the pressure column 1301 and the pressure seat 14 are separated from each other and there is a gap between them. When it is necessary to move the scraper roller 4 away from the diaphragm 10 to reserve space for the diaphragm 10 to pass through the mold, the adjusting mechanism 3 drives the movable seat 310 to move the pressure column 1301 closer to the pressure seat 14 until the pressure column 1301 and the pressure seat 14 are in contact and there is no squeezing effect between them.

[0057] The replacement process for scraper roller 4 is as follows:

[0058] When the scraper roller 4 needs to be replaced, the movable seat 310 is driven by the adjustment mechanism 3 to move the pressure column 1301 towards the pressure seat 14. The pressure seat 14 blocks and pushes the pressure column 1301, causing the pressure column 1301 to move the extrusion block 1302 towards the inside of the carrier frame 11 and compress the first spring 1304. The trapezoidal sides of the extrusion block 1302 slide relative to the sliding sleeve 1306, driving the two sliding sleeves 1306 and the movable frame 1305 to move outward along the guide sleeve 1307, compressing the second spring 1309. At the same time, the round insertion post 1311 on the movable frame 1305 is pushed outward along the guide ring 1101 from the round insertion hole 401 of the scraper roller 4, releasing the insertion limit on the scraper roller 4. At this time, the old scraper roller 4 can be directly removed.

[0059] When installing the new scraper roller 4, align the round insertion holes 401 at both ends of the new scraper roller 4 with the round insertion posts 1311; then, drive the movable seat 310 back through the adjustment mechanism 3 to separate the pressure post 1301 from the pressure seat 14. Under the action of the first spring 1304, the pressure post 1301 drives the squeezing block 1302 to reset. At the same time, under the action of the second spring 1309, the movable frames 1305 on both sides reset inward, and the round insertion posts 1311 are reinserted into the round insertion holes 401 of the new scraper roller 4, realizing the quick installation of the scraper roller 4 and completing the replacement operation.

[0060] like Figures 6-7 As shown, after installation, the fixing block 1308 and the magnetic block 1310 are attached to each other, and the magnetic attraction provides a limit.

[0061] With the above design, after the scraper roller 4 is separated from the diaphragm 10, it is convenient to further disassemble and replace it. Locking or unlocking the scraper roller 4 can be achieved by simply turning the handwheel 303, without the need to switch operating positions, thus improving the continuity of operation.

[0062] In practical implementation, the handwheel 303 can be replaced with a motor. The motor drives the adjustment mechanism 3, and the easy-to-disassemble mechanism 13 works in conjunction with the adjustment mechanism 3 to achieve quick and convenient disassembly and replacement of the scraper roller 4. There is no need to set up separate power sources for the adjustment mechanism 3 and the easy-to-disassemble mechanism 13 or to perform separate manual operations. It is only necessary to control the rotation of the handwheel 303 or drive the first rotating shaft 302 to rotate via the motor.

[0063] This utility model is not limited to the above-described embodiments. Any changes made to its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
