Description

Technical Field

[0001] The utility model relates to the technical field of membrane electrode recycling, in particular to a membrane electrode waste recycling device. Background Art

[0002] In the production process of membrane electrodes, unqualified membrane electrodes are inevitably produced. Since the membrane electrodes contain recyclable coatings such as precious metal platinum, the membrane electrodes are strip-shaped material strips, and the precious metal coatings on the membrane electrodes are relatively easy to scrape off. In traditional membrane electrode waste recycling methods, the precious metal coatings on the material strips are mostly manually scraped off, and the scraped precious metal coatings are collected, purified and reused. Since the recycled material strips may have wrinkles, manual scraping may result in incomplete scraping, and the scraped precious metal coatings are in powder form, which is dispersed in the air, causing pollution to the environment, and are not easy to collect and are prone to loss.

[0003] Therefore, a membrane electrode waste recycling device that solves the above problems is needed. Utility Model Content

[0014] As a preferred technical solution, the waste blowing device includes a pair of first air knives for blowing off membrane electrode waste attached to the scraper and a pair of second air knives for blowing off catalyst waste attached to the brush roller, and the first air knife and the second air knife are both arranged in the membrane electrode waste collecting bucket.

[0020] As a preferred technical solution, each pressing wheel is mounted on the first pressing roller by bolts.

[0021] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0022] Since the membrane electrode waste recycling equipment includes a feeding device, when recycling membrane electrode waste, the first material sorting roller can change the angle of the material belt when it passes through between the pressure wheel and the material belt conveying roller, so that the material belt at the scraper is more closely matched with the material belt conveying roller. The first material sorting roller can also sort the wrinkled material belt to make it smooth and not easy to be scratched and scraped, and there is no dead angle for scraping, so that the scraping is more comprehensive. The second material sorting roller can change the angle of the material belt when it passes through between the second material sorting roller and the material belt conveying roller, so that the material belt at the brush roller is more closely matched with the material belt conveying roller. , so that the brush roller can brush the waste more comprehensively. The settings of the first material sorting roller and the second material sorting roller respectively improve the scraping and brushing effects, thereby increasing the recovery of membrane electrode waste. After the material sorting is completed, the material belt conveying roller rotates under the drive of the servo motor, and the first transmission gear, the second transmission gear and the third transmission gear are engaged to drive the first material sorting roller and the second material sorting roller to rotate, thereby advancing the material belt. This traditional way of using gears avoids the relative movement between the pressure wheel and the material belt, and the pressure wheel presses on both sides of the material belt, thereby preventing the pressure wheel from pressing the material belt. The membrane electrode waste is scraped off, which avoids the loss of membrane electrode waste and increases the recovery of membrane electrode waste. As the material belt moves forward, the front scraper scrapes the membrane electrode waste on the material belt for the first time, and the rear scraper scrapes the membrane electrode waste on the material belt for the second time. The brush roller brushes off the residual membrane electrode waste on the material belt. Multiple scraping and brushing realize the automatic scraping of membrane electrode waste, avoids incomplete scraping of membrane electrode waste, and further increases the recovery of membrane electrode waste. At the same time, the first air knife component scrapes the membrane electrode waste scraped off by the scraper to the membrane electrode Blowing in the waste collection bucket prevents the membrane electrode waste from spreading above the scraper when the scraper scrapes the waste. The second air knife assembly blows down the membrane electrode waste remaining on the back of the brush roller, again avoiding the loss of membrane electrode waste. Under the action of the pulse dust collector, the collection of membrane electrode waste is realized. In the utility model, automatic recycling of membrane electrode waste is realized, and the material belt is sorted by the first material sorting roller and the second material sorting roller to make the material belt smoother and the material belt conveying roller more fitted, thereby improving the effect of scraping and brushing waste, and then increasing the recovery amount of membrane electrode waste.

[0023] Since the pneumatic material belt receiving station includes a brush roller, the brush roller is relatively small, which can reduce the volume occupied by the waste brushing step. At the same time, the brush wire can brush off the membrane electrode waste remaining on the material belt.

[0024] Since the pneumatic material strip splicing table includes a mounting seat, precise positioning between the mounting seat and the mounting frame is achieved through the cooperation between the horizontal connecting protrusion and the horizontal connecting concave block and the cooperation between the precise positioning rod and the precise positioning sleeve. The vertical locking pin is then used for connection to achieve rapid installation and disassembly of the mounting frame, thereby improving the flexibility of the use position of the pneumatic material strip splicing table.

[0059] At least one cutting groove 55 is provided on the top surface of the receiving plate 27 .

[0060] The method of using the utility model is as follows:

[0061] The first step is to place the material strip on the unwinding shaft 41. The material strip first passes through the pneumatic material strip receiving table, then bypasses the first material sorting roller 14, rotates the adjusting screws 20 at both ends of the first pressing roller 6, and the distance between the pressing wheel 7 and the material strip conveying roller 2 becomes larger. Then, the material strip passes between the pressing wheel 7 and the material strip conveying roller 2, and is wound around the bottom of the material strip conveying roller 2. The adjusting screws 20 at both ends of the second pressing roller 9 are rotated. The distance between the second pressing roller 9 and the material strip conveying roller 2 becomes larger, and the material strip passes through between the second pressing roller 9 and the material strip conveying roller 2, bypasses the second material sorting roller 15, and is finally fixed on the receiving shaft 42. The bolts 44 are rotated, and the pressing wheel 7 rotates the two sides of the material strip, so that the adjusting screw 20 is rotated in the opposite direction, so that the material strip is close to the material strip conveying roller 2, and the installation of the material strip is completed.

[0062] In the second step, after the material belt is installed, the unwinding shaft 41, the material belt conveying roller 2 and the material receiving shaft 42 rotate under the drive of the servo motor 45, and the material belt conveying roller 2 drives the first pressing roller 6 and the second pressing roller 9 to rotate, and the material belt moves forward.

[0063] In the third step, as the material belt moves forward, the first material sorting roller 14 sorts the material belt, the scraper 4 scrapes off the membrane electrode waste on the material belt, and the brush roller 5 brushes off the membrane electrode waste remaining on the material belt, thus completing the scraping of the membrane electrode waste.

[0064] In the fourth step, at the same time, the first wind knife 23 scrapes off the membrane electrode waste from the scraper 4, and the second wind knife 24 blows off the membrane electrode waste remaining on the back of the brush roller 5. The scraped membrane electrode waste will fall into the membrane electrode waste collecting bucket 21, and under the action of the pulse dust collector 22, the collection of the membrane electrode waste is completed.

[0065] The fifth step, when a roll of membrane electrode waste is about to be scraped off, place the new material strip on the unwinding shaft 41, pass the new material strip between the corresponding pressing plate 28 and the receiving plate 27, turn the manual adjustment knob 37, and the two sliders 31 move toward the direction close to the material strip. After the positioning plates 29 are respectively against the two sides of the material strip, turn the positioning knob 38 to lock the screw 32. Under the drive of the driving cylinder 53, the corresponding pressing plate 28 descends, and the material strip is pressed against the receiving plate 27 by the pressing plate 28, thus completing the positioning of the material strip.

[0066] In the sixth step, after the material strip is positioned, the material strip is cut along the cutting groove 55 using a tool, and then bonded with tape to complete the material connection.

[0067] The seventh step is to replace the material receiving position, install the mounting seat 25 at the position to be connected, pull out the vertical locking pin 52 between the mounting frame 26 and the mounting seat 25 at the original material receiving position, and then pull out the mounting frame 26 from the mounting seat 25 at the original material receiving position, then install the mounting frame 26 on the mounting seat 25 at the position to be connected, insert the vertical locking pin 52, and start the material receiving work.

[0068] In summary, the utility model realizes the automated recycling of membrane electrode waste, and the material strip is sorted by the first material sorting roller and the second material sorting roller to make the material strip smoother and the material strip conveying roller more fitted, thereby improving the scraping and brushing effects, and further increasing the recycling amount of membrane electrode waste. Gear transmission is adopted between the material strip conveying roller and the first pressing roller, which reduces the relative movement between the pressing wheel and the material strip, thereby avoiding the pressing wheel scraping off the membrane electrode waste on the material strip and avoiding the loss of membrane electrode waste.
