Description

Technical Field

[0001] This invention relates to the field of biogas separation membrane production technology, specifically to an online ultrasonic coating device for biogas separation membrane fiber production. Background Technology

[0002] In the production process of biogas separator membranes, the coating of membrane fibers is a crucial step, as the coating quality directly affects the performance of the biogas separator membrane, including its separation efficiency, durability, and service life. Traditional biogas separator membrane fiber coating methods mainly rely on static coating or simple dynamic coating techniques, which have significant limitations in terms of coating uniformity, coating efficiency, and coating adhesion.

[0003] Specifically, static coating methods typically involve fixing the membrane filament in a certain position and then applying the coating material to the filament surface through spraying or dip coating. While this method is simple to operate, it is difficult to ensure a uniform distribution of the coating layer on the membrane filament surface, especially when dealing with long or complex-shaped membrane filaments, where coating quality is even more difficult to guarantee. In addition, static coating methods have low coating efficiency, making it difficult to meet the needs of large-scale industrial production.

[0004] While simple dynamic coating technology can improve coating uniformity by moving film filaments or coating equipment, it still suffers from problems such as weak coating adhesion and serious waste of coating materials. Especially on high-speed production lines, traditional dynamic coating technology often struggles to stably control the coating process, resulting in large fluctuations in coating quality and poor product consistency.

[0005] With the continuous expansion of the biogas separation membrane market and its application fields, the requirements for membrane fiber coating quality are also becoming increasingly stringent. Therefore, developing an efficient, uniform, and stable online coating technology has become crucial for improving the production efficiency and product quality of biogas separation membranes.

[0020] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Please refer to Figures 1-11As shown, an online ultrasonic coating device for biogas separation membrane fiber production includes a body 1. An ultrasonic atomizer 103, a water pump 105, a compressor pump 107, and an air pump 108 are mounted on the top of the body 1. The output end of the ultrasonic atomizer 103 is connected to a spray head 104. The input end of the ultrasonic atomizer 103 is connected to both the water pump 105 and the compressor pump 107. The input end of the compressor pump 107 is connected to the output end of the air pump 108. The ultrasonic atomizer 103, water pump 105, compressor pump 107, and air pump 108 are connected in series. Openings are located on both sides of the interior of the body 1. The device has slots 101, one set of which has an auxiliary tube 102. The end of the auxiliary tube 102 is fitted with a clamping mechanism 2. The body 1 is also connected to a traction mechanism 3. The clamping mechanism 2 and the traction mechanism 3 are used to pass the end of the membrane filament through the body 1. The top of the body 1 is welded with a vertical plate 106. The outside of the vertical plate 106 is provided with a control mechanism 4, a switch mechanism 5 and an adjustment mechanism 6. The control mechanism 4, the switch mechanism 5 and the adjustment mechanism 6 are used to control the start-up and power adjustment of the ultrasonic atomizer 103, the water pump 105, the compressor pump 107 and the air pump 108. The bottom of the interior of the body 1 contains a coating agent, and the input end of the water pump 105 is connected to the bottom of the interior of the body 1.

[0022] Example 2 Please refer to Figure 1 , Figure 3 and Figure 4 As shown, the clamping mechanism 2 includes a disc 201 fixedly connected to the end of the auxiliary tube 102. A drive motor 206 is mounted on the outer wall of the disc 201. The output end of the drive motor 206 extends into the disc 201 and is fixedly connected to the drive gear 203. A set of rotating gear rings 202 and several sets of driven gears 204 are also rotatably connected inside the disc 201. The outer teeth of the rotating gear ring 202 mesh with the drive gear 203, and the inner teeth of the rotating gear ring 202 mesh with several sets of driven gears 204. Several sets of clamping members 205 are also slidably connected inside the disc 201. Teeth that mesh with several sets of driven gears 204 are fixedly connected to the clamping members 205.

[0023] Those skilled in the art will understand that the output of the drive motor 206 drives the drive gear 203 to rotate, causing the rotating gear ring 202 to rotate, which in turn drives all the driven gears 204 to rotate synchronously, so that all the clamping parts 205 move synchronously toward or away from the center position of the disc body 201.

[0024] Example 3 Please refer to Figure 6As shown, the traction mechanism 3 includes a first lead screw 301 and a first guide rod 302. The first lead screw 301 is rotatably connected to the inside of the machine body 1, and the first guide rod 302 is fixedly connected to the inside of the machine body 1. A first movable plate 304 is slidably connected to the outer wall of the first guide rod 302. The first movable plate 304 is threadedly connected to the first lead screw 301. A first stepper motor 303 for driving the first lead screw 301 to rotate is provided on the outer wall of the machine body 1, and a first electric push rod 305 is provided on the outer wall of the first movable plate 304. The output end of the first electric push rod 305 is connected to a first dual-axis electric push rod 306 through a connector. Both output ends of the first dual-axis electric push rod 306 are equipped with first clamping blocks 307.

[0025] Please refer to Figure 6 As shown, the traction mechanism 3 also includes a second electric push rod 308 and a second movable plate 309. The second electric push rod 308 is fixedly connected to the outer wall of the body 1. The second movable plate 309 is fixedly installed at the output end of the second electric push rod 308. A second dual-axis electric push rod 310 is fixedly connected inside the second movable plate 309. A second clamping block 311 is fixedly connected to both output ends of the second dual-axis electric push rod 310.

[0026] Those skilled in the art will understand that by controlling the output end of the first stepper motor 303 to rotate, the first lead screw 301 rotates, causing the first movable plate 304 to move horizontally back and forth along the outer wall of the first guide rod 302, thereby driving the two sets of first clamping blocks 307 to move horizontally back and forth; and by controlling the output end of the first electric push rod 305 to extend or retract, the two sets of first clamping blocks 307 are driven to move back and forth; and by controlling the two output ends of the first dual-axis electric push rod 306 to extend or retract synchronously, the two sets of first clamping blocks 307 are driven to move away from or closer to each other. In addition, by controlling the output end of the second electric push rod 308 to extend or retract, the two sets of second clamping blocks 311 are driven to reciprocate left and right in the horizontal direction; and by controlling the two output ends of the second dual-axis electric push rod 310 to extend or retract synchronously, the two sets of second clamping blocks 311 are driven to move away from or closer to each other.

[0027] Example 4 Please refer to Figure 7As shown, the control mechanism 4 includes a second lead screw 402 and a first lifting block 405. A frame 401 is fixedly connected to the front side of the upright plate 106. The second lead screw 402 is rotatably installed inside one side of the frame 401. The first lifting block 405 is threadedly connected to the second lead screw 402. A second guide rod 403 is also welded inside one side of the frame 401. The first lifting block 405 is slidably connected to the second guide rod 403. A second stepper motor 404 is provided on the top of the frame 401. The top of the second lead screw 402 is fixedly connected to the output end of the second stepper motor 404. A first toothed plate 406 and a rod body 407 are fixedly connected to both sides of the first lifting block 405, respectively.

[0028] Please refer to Figure 7 As shown, the control mechanism 4 also includes a second lifting block 409. A fixed rod 408 is fixedly connected to the inside of the other side of the frame 401. The second lifting block 409 is slidably connected to the outer wall of the fixed rod 408. The inner wall of the frame 401 is fixedly connected to the second lifting block 409 through a first spring 410. A first sliding rod 411 is slidably connected inside the second lifting block 409. A second spring 413 is sleeved on the outside of the first sliding rod 411. The outer end of the first sliding rod 411 is fixedly connected to the sliding block 412. A second toothed plate 414 is also fixedly installed on the outside of the second lifting block 409. A fixed block 415 is fixedly installed on the top front side of the upright plate 106.

[0029] Those skilled in the art will understand that by controlling the output end of the second stepper motor 404 to rotate, the second lead screw 402 rotates, causing the first lifting block 405, the first toothed plate 406, and the rod 407 to move upward as a whole. When the rod 407 moves upward, it supports the sliding block 412 and causes it to move upward as well, thereby causing the second lifting block 409, the second toothed plate 414, and the sliding block 412 to move upward as a whole. The first spring 410 is in a contracted state, and when the inclined surface of the sliding block 412 contacts the inclined surface of the fixed block 415, it will drive the sliding block 412 to retract into the interior of the second lifting block 409. Then the second spring 413 is also in a contracted state. After that, the rod 407 no longer supports the bottom of the sliding block 412. Under the action of the first spring 410 restoring its deformation, the second lifting block 409, the second toothed plate 414, and the sliding block 412 move downward as a whole to reset. At the same time, the second spring 413 also restores its deformation, causing the sliding block 412 to reset. Next, the output end of the reverse-driven second stepper motor 404 rotates, causing the first lifting block 405, the first toothed plate 406 and the rod 407 to move downward as a whole. When the rod 407 moves downward, it contacts the inclined surface of the sliding block 412, which will also drive the sliding block 412 to retract into the interior of the second lifting block 409, so that the rod 407 can "bypass" the sliding block 412 and be located below the sliding block 412.

[0030] Example 5 Please refer to Figure 10 and Figure 11 As shown, the switching mechanism 5 includes a first rotating shaft 501 rotatably connected within the upright plate 106. The two ends of the first rotating shaft 501 are fixedly connected to the first gear 502 and the first bevel gear 503, respectively. When the first spring 410 hangs down naturally, the first gear 502 does not mesh with the second toothed plate 414. Two sets of first support plates 504 are fixedly installed on the rear side of the upright plate 106. A third lead screw 505 is rotatably connected between the two sets of first support plates 504. A pressing plate 508 is threadedly connected to the outer wall of the third lead screw 505. The pressing plate 508 is slidably connected to the third guide rod 506. The third guide rod 506 is welded between the two sets of first support plates 504. A second bevel gear 507 that meshes with the first bevel gear 503 is fixedly connected to the outer end of the third lead screw 505.

[0031] Please refer to Figure 10 and Figure 11 As shown, the switch mechanism 5 also includes a second support plate 509 welded to the rear side of the upright plate 106. A frame 510 is fixedly connected to the top of the second support plate 509. A third spring 511 is fixedly installed at the bottom of the inner part of the frame 510. The other end of the third spring 511 is connected to the switch 512. A false heart-shaped groove 513 is opened on the front side of the switch 512. A second sliding rod 516 is fixedly connected to the top of the switch 512. The second sliding rod 516 is slidably connected to the frame 510. The second sliding rod 516 is located directly below the pressing plate 508.

[0032] Please refer to Figure 10 and Figure 11 As shown, a rotating component 514 is rotatably connected to the bottom front side of the frame 510, and a sliding component 515 is provided at the other end of the rotating component 514. The sliding component 515 is slidably connected to the false heart-shaped groove 513.

[0033] Those skilled in the art will understand that when the first gear 502 rotates, the first shaft 501 and the first bevel gear 503 rotate as a whole, which drives the second bevel gear 507 and the third lead screw 505 to rotate as a whole, causing the pressing plate 508 to move downward and press the second sliding rod 516, causing the switch 512 to move downward. The third spring 511 is in a contracted state, the rotating part 514 rotates, and the sliding part 515 rotates clockwise in the false heart-shaped groove 513. The sliding part 515 moves from the bottom of the false heart-shaped groove 513 to the middle position of the top of the false heart-shaped groove 513 and stops there, thereby pressing down the switch 512 and fixing it at that height, thereby connecting the circuit. The ultrasonic atomizer 103, water pump 105, compressor pump 107 and air pump 108 are connected in series to achieve simultaneous start-up. Afterwards, the first gear 502 rotates in the opposite direction, causing the second bevel gear 507 and the third lead screw 505 to rotate in the opposite direction as a whole, driving the pressing plate 508 to move upward. The switch 512 is still in the pressed state, controlling the ultrasonic atomizer 103, water pump 105, compressor pump 107 and air pump 108 to continue to work. Next, under the action of the rotation of the first gear 502, the pressing plate 508 continues to move downward again, pressing the second sliding rod 516 a second time. The pressing plate 508 then quickly moves upward to the reset state. Under the action of the third spring 511 restoring its deformation, the sliding member 515 rotates clockwise from the middle position of the top of the false heart-shaped groove 513, moving to the reset state. The switch 512 moves upward, disconnecting the circuit, causing the ultrasonic atomizer 103, water pump 105, compressor pump 107 and air pump 108 to stop working.

[0034] Example 6 Please refer to Figure 8 As shown, the adjusting mechanism 6 includes a fourth lead screw 605 and a sliding contact 607. A second rotating shaft 601 is rotatably connected inside the vertical plate 106. A second gear 602 and a third bevel gear 603 are fixedly connected to both ends of the second rotating shaft 601, respectively. The fourth lead screw 605 is rotatably connected between two sets of third support plates 604. Both sets of third support plates 604 are fixedly installed on the rear side of the vertical plate 106. The sliding contact 607 is threaded onto the fourth lead screw 605. A fourth guide rod 606 is welded between the support plates 604. The sliding contact 607 is slidably connected to the fourth guide rod 606, and the bottom of the fourth lead screw 605 is fixedly connected to the fourth bevel gear 608. The fourth bevel gear 608 meshes with the third bevel gear 603. The end of the sliding contact 607 is located on the sliding rheostat 609. The sliding rheostat 609 is also located on the rear side of the vertical plate 106. When the first lifting block 405 moves downward, the first toothed plate 406 meshes with the second gear 602.

[0035] Those skilled in the art will understand that when the second gear 602 rotates, the second shaft 601 and the third bevel gear 603 rotate as a whole, driving the fourth bevel gear 608 and the fourth lead screw 605 to rotate as a whole. Consequently, the sliding contact 607 moves up and down along the outer wall of the fourth guide rod 606, changing the position of the sliding contact 607 on the sliding rheostat 609. The sliding rheostat 609 is also connected in series in the circuit, thereby changing the resistance in the circuit and adjusting the current in the circuit. This allows for the adjustment of the power of the ultrasonic atomizer 103, water pump 105, compressor pump 107, and air pump 108.

[0036] The working principle of this invention is as follows: S1. The auxiliary tube 102 is inserted into one of the slots 101, and the end of the auxiliary tube 102 is placed at the discharge point of the previous process. The biogas separation membrane filaments are conveyed to the end of the auxiliary tube 102. The output end of the drive motor 206 drives the drive gear 203 to rotate, causing the rotating gear ring 202 to rotate, which in turn drives all the driven gears 204 to rotate synchronously, so that all the clamping parts 205 move synchronously towards the center position close to the disc 201 to clamp the end of the membrane filaments. S2. The two sets of first clamping blocks 307 approach each other and clamp the outer wall of the auxiliary tube 102. Under the action of the output end of the first stepper motor 303, the auxiliary tube 102 is driven to move to the left, so that the end of the membrane filament is located inside the annular spray head 104. S3. By controlling the output of the second stepper motor 404 to rotate, the second lead screw 402 rotates, causing the first lifting block 405, the first toothed plate 406, and the rod 407 to move upward as a whole. When the rod 407 moves upward, it supports the sliding block 412 and causes it to move upward as well, thereby causing the second lifting block 409, the second toothed plate 414, and the sliding block 412 to move upward as a whole. The first spring 410 is in a contracted state. When the second toothed plate 414 moves upward, it meshes with the first gear 502 and drives it to rotate, causing the first rotating shaft 501 and the first bevel gear 503 to rotate as a whole, which in turn causes the second bevel gear 507 and the third lead screw 505 to rotate as a whole, causing the pressing plate 508 to move downward. Pressing the second sliding rod 516 causes the switch 512 to move downwards, the third spring 511 to be in a contracted state, the rotating part 514 to rotate, and the sliding part 515 to rotate clockwise in the false heart-shaped groove 513. The sliding part 515 moves from the bottom of the false heart-shaped groove 513 to the middle position of the top of the false heart-shaped groove 513 and stops there, thereby pressing down the switch 512 and fixing it at that height, thus connecting the circuit. The ultrasonic atomizer 103, water pump 105, compressor pump 107 and air pump 108 are connected in series to start simultaneously. The ultrasonic atomizer 103 mixes and atomizes the dry compressed air and spray into an ultra-fine uniform mist to coat the separation membrane filaments. S4. Under the combined action of the output end of the first stepper motor 303 and the output end of the second electric push rod 308, the auxiliary tube 102 is made to pass through the machine body 1, and the separation membrane filaments are also made to pass through the machine body 1. It is worth noting that the auxiliary tube 102 located outside the machine body 1 can also be reset under the action of the traction mechanism 3. S5. When the power needs to be adjusted during the coating process, when the inclined surface of the sliding block 412 contacts the inclined surface of the fixed block 415, the sliding block 412 will be driven to retract into the interior of the second lifting block 409. The second spring 413 will also be in a contracted state. After that, the rod 407 will no longer support the bottom of the sliding block 412. Under the action of the first spring 410 restoring its deformation, the second lifting block 409, the second toothed plate 414 and the sliding block 412 will move downward as a whole to reset. At the same time, the second spring 413 will also restore its deformation, causing the sliding block 412 to reset. The downward movement of the second toothed plate 414 will drive the first gear 502 to rotate in the opposite direction, causing the second bevel gear 507 and the third lead screw 505 to rotate in the opposite direction, driving the pressing plate 508 to move upward. The switch 512 is still in the pressed state, controlling the ultrasonic atomizer 103, water pump 105, compressor pump 107 and air pump 108 to continue to work. Next, the output of the second stepper motor 404 is rotated, causing the first lifting block 405, the first toothed plate 406, and the rod 407 to move downwards as a whole. As the rod 407 moves downwards, it contacts the inclined surface of the sliding block 412, which in turn drives the sliding block 412 to retract into the interior of the second lifting block 409. This allows the rod 407 to "bypass" the sliding block 412 and be positioned below it, continuing its downward movement. This causes the first toothed plate 406 to mesh with the second gear 602 and rotate, causing the second rotating shaft 601 to... The rotation of the third bevel gear 603 as a whole drives the fourth bevel gear 608 and the fourth lead screw 605 to rotate as a whole. This causes the sliding contact 607 to reciprocate up and down along the outer wall of the fourth guide rod 606, changing the position of the sliding contact 607 on the sliding rheostat 609. The sliding rheostat 609 is also connected in series in the circuit, thereby changing the resistance in the circuit and adjusting the current in the circuit. This allows for the adjustment of the power of the ultrasonic atomizer 103, water pump 105, compressor pump 107, and air pump 108. S6. When it is necessary to pause the work, the pressing plate 508 continues to move downward again under the action of the first gear 502, pressing the second sliding rod 516 a second time. The pressing plate 508 then quickly moves upward to the reset state. Under the action of the third spring 511 restoring its deformation, the sliding member 515 rotates clockwise from the middle position of the top of the false heart-shaped groove 513 to the reset state. The switch 512 moves upward to disconnect the circuit, so that the ultrasonic atomizer 103, water pump 105, compressor pump 107 and air pump 108 stop working. It is convenient, quick and fully automated.
