Description

Technical Field

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

[0002] With the development of environmentally friendly energy technologies, biogas, as a clean and renewable energy source, is receiving increasing attention for its development and utilization. In the production process of biogas separation membranes, the surface cleanliness of the membrane fibers (hollow fiber membrane fibers) directly determines their permeability, separation efficiency, and service life. Because membrane fibers are typically made of polymer materials and have a relatively thin diameter and long length, tiny dust particles, oil residues, or unreacted monomer impurities easily adhere to their surface during spinning and subsequent processing.

[0003] Currently, in the field of membrane fiber production, common cleaning methods mainly involve manual wiping or simple immersion cleaning. However, existing technologies have the following significant drawbacks: Low cleaning efficiency and poor uniformity: manual cleaning is labor-intensive and it is difficult to ensure that the surface of each membrane fiber is evenly stressed, which can easily cause damage or breakage of the membrane fibers; simple soaking cleaning cannot effectively remove firmly attached micro-impurities, and the cleaning effect is not ideal.

[0004] Lack of dynamic adhesion cleaning mechanism: Traditional ultrasonic cleaning devices are mostly fixed. When the membrane fibers pass through the cleaning fluid, they rely solely on the cavitation effect of ultrasonic waves for cleaning, lacking physical contact wiping with the membrane fiber surface. This limits their ability to remove stubborn stains, and simple ultrasonic vibration may cause the membrane fibers to entangle or knot.

[0005] Inconvenient equipment maintenance: After long-term use, a large amount of impurities and dirt detached from the membrane fibers will accumulate on the inner wall and bottom of the cleaning tank; existing cleaning tanks mostly require manual cleaning after the machine is stopped, which is not only time-consuming and labor-intensive, but also prone to leaving dead corners, causing secondary contamination of the membrane fibers by the cleaning solution and affecting product yield.

[0006] Inflexible power adjustment: Biogas separation membrane fibers of different materials and specifications have different tolerances to ultrasonic waves and different cleaning requirements; most existing equipment has fixed power or crude adjustment methods, which cannot make precise and automated power adjustment according to actual production needs, resulting in poor versatility and applicability of the equipment.

Detailed Implementation

[0021] 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.

[0022] Example 1 Please refer to Figures 1-9 As shown, an ultrasonic cleaning device for automated biogas separation membrane fiber production includes a body 1. A cleaning tank 101 is provided on the top of the body 1. An ultrasonic device 103 is installed on the left side wall inside the cleaning tank 101. First guide wheels 102 are connected to both sides of the top of the body 1. A pressing mechanism 2 is provided on the rear side plate of the top of the body 1. A bonding mechanism 3 and a cleaning mechanism 4 are installed on the front side of the top of the body 1. The cleaning mechanism 4 is used to clean the inner wall of the cleaning tank 101. An equipment cabinet 108 is also provided on the front side of the body 1. A control mechanism 5 and an adjustment mechanism 6 are installed inside the equipment cabinet 108. The control mechanism 5 and the adjustment mechanism 6 cooperate to control the start-up of the ultrasonic device 103 and adjust the power of the ultrasonic device 103.

[0023] Example 2 Please refer to Figure 1 and Figure 3As shown, the pressing mechanism 2 includes a first lead screw 202 and a first guide rod 203. Two sets of the first lead screw 202 are provided, and the two ends of the first lead screw 202 are rotatably connected to the inside of two sets of fixed blocks 201 respectively. Two sets of the first guide rod 203 are also provided and fixedly installed between the two sets of fixed blocks 201 respectively. An L-shaped part 205 is threadedly connected to the outer wall of the first lead screw 202. A second guide wheel 206 is rotatably connected inside the vertical plate of the L-shaped part 205. The vertical plate of the L-shaped part 205 is slidably connected to the first guide rod 203. A rotating wheel 204 is fixedly connected to the outer end of each set of the first lead screw 202. The two sets of rotating wheels 204 are connected by belt drive. A first stepper motor 207 is provided at the bottom of one set of fixed blocks 201. The outer end of one set of the first lead screw 202 is fixedly connected to the output end of the first stepper motor 207.

[0024] Those skilled in the art will understand that the output of the first stepper motor 207 drives one set of first lead screws 202 and rotating wheels 204 to rotate as a whole. Driven by the belt, the other set of rotating wheels 204 and first lead screws 202 also rotate synchronously. As a result, the two sets of L-shaped parts 205 move up and down in sync, thereby driving the two sets of second guide wheels 206 to move up and down in sync. During production, the membrane fibers pass over the top of the first guide wheels 102 on both sides and are in a horizontal state. When the two sets of second guide wheels 206 move down synchronously, they press the membrane fibers down into the cleaning liquid inside the cleaning tank 101. At this time, the membrane fibers located between the two sets of second guide wheels 206 are also in a horizontal state.

[0025] Example 3 Please refer to Figure 4 As shown, the bonding mechanism 3 includes a first fixed frame 301 fixedly installed on the front side of the top of the machine body 1. A second lead screw 302 is rotatably connected inside the first fixed frame 301. A lifting plate 305 is threadedly connected to the outer wall of the second lead screw 302. The lifting plate 305 is slidably connected to the second guide rod 303. The second guide rod 303 is fixedly connected inside the first fixed frame 301. The outer end of the second lead screw 302 is fixedly installed on the output end of the second stepper motor 304. The second stepper motor 304 is located on the top of the first fixed frame 301.

[0026] Please refer to Figure 4As shown, the bonding mechanism 3 also includes a threaded rod 306 and a fixed rod 307. The threaded rod 306 is rotatably connected to the bottom of the lifting plate 305, and the fixed rod 307 is welded to the bottom of the lifting plate 305. Two sets of movable plates 309 are slidably connected to the outer wall of the fixed rod 307. The two sets of movable plates 309 are respectively threaded to both ends of the outer wall of the threaded rod 306. The threads at both ends of the threaded rod 306 are in opposite directions. A servo motor 308 for driving the threaded rod 306 to rotate is also installed at the bottom of the lifting plate 305. A detachable cleaning cotton 310 is provided on the side of the two sets of movable plates 309 that are close to each other.

[0027] Those skilled in the art will understand that the output of the second stepper motor 304 drives the second lead screw 302 to rotate, causing the lifting plate 305 to move downwards along the outer wall of the second guide rod 303, which in turn drives the two sets of movable plates 309 to move downwards and extend into the cleaning fluid. At this time, the two sets of cleaning cotton 310 are located at the appropriate height for the membrane fibers. In addition, the output of the servo motor 308 drives the threaded rod 306 to rotate, causing the two sets of movable plates 309 to move closer to each other, thereby driving the two sets of cleaning cotton 310 to move closer to each other and contact the horizontal membrane fiber surface in the cleaning fluid. With the two sets of first guide wheels 102 and two sets of second guide wheels 206 continuing to transport the membrane fibers, the membrane fibers move in the cleaning fluid and pass through the two sets of cleaning cotton 310, thereby achieving cleaning.

[0028] Example 4 Please refer to Figure 5 As shown, the cleaning mechanism 4 includes a third lead screw 402 and a third guide rod 403. The top of the machine body 1 is fixedly connected to a second fixed frame 401 by bolts. The third lead screw 402 is rotatably connected inside the second fixed frame 401. The third guide rod 403 is fixedly installed inside the second fixed frame 401. An L-shaped plate 405 is slidably connected to the outer wall of the third guide rod 403. The horizontal plate of the L-shaped plate 405 is threadedly connected to the third lead screw 402. The outer end of the third lead screw 402 is fixedly installed at the output end of the third stepper motor 404. The third stepper motor 404 is located at the top of the second fixed frame 401, and the bottom of the vertical plate of the L-shaped plate 405 is fixedly connected to the cleaning frame 406.

[0029] Please refer to Figure 2 As shown, a first electric push rod 104 is fixedly connected to the back of the machine body 1. The output end of the first electric push rod 104 extends into the cleaning tank 101 and is fixedly connected to the push plate 105. A waste outlet is opened on the front side of the machine body 1. A cover plate 107 is provided outside the waste outlet. The cover plate 107 is fixedly connected to the output end of the second electric push rod 106. The second electric push rod 106 is provided on the outer wall of the front side of the machine body 1.

[0030] Those skilled in the art will understand that when it is necessary to clean the inner wall of the cleaning tank 101, the cleaning liquid in the cleaning tank 101 is drained, and the output end of the third stepper motor 404 drives the third lead screw 402 to rotate, causing the L-shaped plate 405 to move downward or upward along the outer wall of the third guide rod 403, thereby realizing the downward or upward movement of the cleaning frame 406. During the downward or upward movement of the outer wall of the cleaning frame 406, the four inner walls of the cleaning tank 101 are scraped, so that the "impurities" remaining on the four inner walls of the cleaning tank 101 are scraped clean and fall to the bottom of the cleaning tank 101. Finally, under the contraction action of the output end of the second electric push rod 106, the cover plate 107 moves upward to open the waste outlet, and in conjunction with the extension of the output end of the first electric push rod 104, it drives the push plate 105 to push forward along the bottom wall of the cleaning tank 101, thereby realizing the complete ejection of the "impurities" at the bottom of the cleaning tank 101.

[0031] Example 5 Please refer to Figure 6 and Figure 8 As shown, the control mechanism 5 includes a third fixed frame 501 fixedly connected to the rear side of the equipment cabinet 108. A fourth stepper motor 502 is installed at the bottom of one side of the third fixed frame 501. The output end of the fourth stepper motor 502 is fixedly connected to a fourth lead screw 503. A lifting block 505 is threadedly connected to the fourth lead screw 503. The lifting block 505 is slidably connected to the fourth guide rod 504. A rack 506 and a support rod 507 are fixedly installed on the outer wall of the lifting block 505.

[0032] Please refer to Figure 6 , Figure 8 and Figure 9 As shown, a first slide rod 508 is fixedly connected to the inside of the other side of the third fixed frame 501. A first spring 509 is sleeved on the outside of the first slide rod 508. A lifting frame 510 is fixedly connected to the bottom of the first spring 509. The lifting frame 510 is slidably connected to the first slide rod 508. A second slide rod 511 is slidably connected inside the lifting frame 510. A first irregular block 513 is fixedly installed on the outer end of the second slide rod 511. A second spring 512 is sleeved on the outside of the second slide rod 511. A second irregular block 514 is provided on the top front side of the third fixed frame 501. A pressing plate is fixedly connected to the outer wall of the lifting frame 510. A switch 515 is provided directly below the pressing plate. The switch 515 is electrically connected to the ultrasonic device 103.

[0033] Please refer to Figure 7As shown, the adjustment mechanism 6 includes a fourth fixed frame 601 fixedly installed inside the right side of the equipment cabinet 108. A fifth lead screw 602 is rotatably connected inside the fourth fixed frame 601. A slider 605 is threadedly connected to the fifth lead screw 602. The slider 605 is slidably connected to the fifth guide rod 603. The fifth guide rod 603 is fixedly installed inside the fourth fixed frame 601. The outer end of the fifth lead screw 602 extends to the outside of the fourth fixed frame 601 and is fixedly connected to the gear 604. A sliding rheostat 606 is also provided inside the right side of the equipment cabinet 108. The slider 605 contacts the sliding rheostat 606. The rotation of the gear 604 is driven by the movement of the rack 506.

[0034] Those skilled in the art will understand that the output of the fourth stepper motor 502 drives the fourth lead screw 503 to rotate, causing the lifting block 505 to move upward. The support rod 507 supports the bottom of the first irregular block 513 and moves upward, causing the lifting frame 510 to move upward as well. The first spring 509 is in a contracted state. When the inclined surface of the first irregular block 513 contacts the inclined surface of the second irregular block 514, the first irregular block 513 contracts into the interior of the lifting frame 510. At this time, the second spring 512 is also in a contracted state, and the support rod 507 no longer supports the bottom of the first irregular block 513. Under the action of the first spring 509 restoring its deformation, the lifting frame 510 moves downward rapidly, causing the pressing plate to move downward rapidly as well, pressing the switch 515, thereby activating the ultrasonic device 103. Continuing to drive the output of the fourth stepper motor 502 to rotate in the opposite direction, the lifting block 505 moves downward, causing the support rod 507 to move downward as well. When the support rod 507 contacts the inclined surface of the first irregular block 513, the first irregular block 513 can retract into the interior of the lifting frame 510, and the support rod 507 can then bypass the first irregular block 513 and move to a position below the first irregular block 513, in the reset state. As the lifting block 505 continues to move downward, it drives the rack 506 to continue moving downward and mesh with the gear 604 for driving. When it rotates, it drives the fifth lead screw 602 to rotate, which in turn drives the slider 605 to move along the sliding rheostat 606. If the rack 506 is engaged with the gear 604 and the rack 506 is driven to move upward, the slider 605 will move in the opposite direction on the sliding rheostat 606, thereby adjusting the current and thus adjusting the power of the ultrasonic device 103. In real life, different membrane fibers require different ultrasonic powers for cleaning, so this device is easy to adjust the power and is automatically adjusted, which is convenient and quick, improving the applicability of the device.

[0035] To clearly describe the working principle of this invention, we will use... Figure 1This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. During production, the membrane filament passes over the top of the first guide rollers 102 on both sides and is in a horizontal state. The output end of the first stepper motor 207 drives one set of first lead screws 202 and rotating wheels 204 to rotate as a whole. Driven by the belt, the other set of rotating wheels 204 and first lead screws 202 also rotate synchronously. Then, the two sets of L-shaped parts 205 move downward synchronously, thereby driving the two sets of second guide rollers 206 to move downward synchronously, so as to press the membrane filament downward into the cleaning liquid inside the cleaning tank 101. At this time, the membrane filament located between the two sets of second guide rollers 206 is also in a horizontal state. S2. The output end of the second stepper motor 304 drives the second lead screw 302 to rotate, causing the lifting plate 305 to move downward along the outer wall of the second guide rod 303, which in turn drives the two sets of movable plates 309 to move downward and extend into the cleaning solution. At this time, the two sets of cleaning cotton 310 are located at the appropriate height of the membrane fibers. In addition, the output end of the servo motor 308 drives the threaded rod 306 to rotate, causing the two sets of movable plates 309 to move closer to each other, thereby driving the two sets of cleaning cotton 310 to move closer to each other and contact the horizontal membrane fiber surface in the cleaning solution. S3. The output of the fourth stepper motor 502 drives the fourth lead screw 503 to rotate, causing the lifting block 505 to move upward. The support rod 507 supports the bottom of the first irregular block 513 and moves upward, causing the lifting frame 510 to move upward as well. The first spring 509 is in a contracted state. When the inclined surface of the first irregular block 513 contacts the inclined surface of the second irregular block 514, the first irregular block 513 contracts into the interior of the lifting frame 510. At this time, the second spring 512 is also in a contracted state, and the support rod 507 no longer supports the bottom of the first irregular block 513. Under the action of the first spring 509 restoring its deformation, the lifting frame 510 moves downward quickly, causing the pressing plate to move downward quickly as well, pressing the switch 515, thereby activating the ultrasonic device 103. S4. Continue to drive the output end of the fourth stepper motor 502 to rotate in the opposite direction, and the lifting block 505 will move downward, driving the support rod 507 to move downward as well. When the support rod 507 also contacts the inclined surface of the first irregular block 513, the first irregular block 513 can also be caused to retract into the interior of the lifting frame 510. The support rod 507 can then bypass the first irregular block 513 and move to the position below the first irregular block 513, which is the reset state. When the lifting block 505 continues to move downward, it drives the rack 506 to continue to move downward and mesh with the gear 604 to drive it to rotate, driving the fifth lead screw 602 to rotate, and driving the slider 605 to move along the sliding rheostat 606. If the rack 506 is driven to move upward during the meshing process of the rack 506 and the gear 604, the slider 605 will move in the opposite direction on the sliding rheostat 606, thereby realizing the adjustment of the current and thus adjusting the power of the ultrasonic device 103 according to the type of membrane fiber. S5. Under the condition of being transported by two sets of first guide wheels 102 and two sets of second guide wheels 206, the membrane fibers move in the cleaning solution and pass through two sets of cleaning cotton 310, and are cleaned under the action of ultrasonic device 103. S6. When it is necessary to clean the inner wall of the cleaning tank 101, the cleaning liquid in the cleaning tank 101 is drained. The output end of the third stepper motor 404 drives the third lead screw 402 to rotate, causing the L-shaped plate 405 to move downward or upward along the outer wall of the third guide rod 403. This causes the cleaning frame 406 to move downward or upward. During the downward or upward movement of the outer wall of the cleaning frame 406, the four inner walls of the cleaning tank 101 are scraped, so that the "impurities" remaining on the four inner walls of the cleaning tank 101 are scraped clean and fall to the bottom of the cleaning tank 101. Finally, under the contraction action of the output end of the second electric push rod 106, the cover plate 107 moves upward to open the waste outlet. In conjunction with the extension of the output end of the first electric push rod 104, the push plate 105 is pushed forward along the bottom wall of the cleaning tank 101, thereby pushing out all the "impurities" at the bottom of the cleaning tank 101. No manual cleaning is required, which is convenient and quick.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.
