Background
The ultrafiltration membrane is a microporous filtration membrane with the pore size specification being consistent and the rated pore size range being 0.001-0.02 mu m, solute molecules smaller than the pore size can be screened out by applying proper pressure on one side of the membrane so as to separate particles with the molecular weight being more than 500 daltons and the particle size being more than 10 nm.
At present, a flat ultrafiltration membrane can be prepared by a flat membrane scraping machine, and the main preparation process of the flat ultrafiltration membrane is as follows: non-woven fabrics or other materials are laid on a workbench of the film scraping machine to serve as carriers, the film forming liquid is evenly spread on the carriers by using the film scraping mechanism, then the film body is solidified in water, and finally the film body is sent to be dried. In the above process, when the membrane-forming solution is poured onto the carrier (on the worktable), the worker usually pours the membrane-forming solution onto the carrier manually, so that the membrane-forming solutions on the carrier are stacked together, and the initial thickness of the membrane-forming solution is thick, which is not beneficial to the leveling of the membrane-forming solution. In addition, in the scraping and coating process, the thickness of the film-forming liquid is increased under the pushing action of the film-scraping plate, more film-forming liquid can be adhered to the film-scraping plate, the film-forming liquid is wasted, and the cleaning workload of the subsequent film-scraping plate is increased.

Guide roll 24 rotates to be connected in the left and right sides of workstation 2, specifically, two mounting panels 29 that set up relatively are all welded on the left side of workstation 2, the right side, sets up the through hole that supplies guide roll 24 to pass on the mounting panel 29, and the distance between guide roll 24's bottom and the workstation 2 equals the thickness of carrier. The equal coaxial rotation in both ends of tensioning roller 25 is connected with the lantern ring 30, and the telescopic link 31 of the vertical setting of the 30 fixedly connected with of lantern ring, the periphery cover of telescopic link 31 are equipped with elastic component II 32, and workstation 2's lateral wall fixedly connected with backup pad 33, telescopic link 31's bottom links to each other with backup pad 33, and the both ends of elastic component II 32 offset with the lantern ring 30, backup pad 33 respectively. In this embodiment, two guide rollers 24 are located between two tension rollers 25, and the elastic member i 20 and the elastic member ii 32 are both springs.
The work table 2 is located the basin 3, contains water in the basin 3, and the liquid level is less than the upper surface of work table 2, and the diapire of basin 3 bonds and has inflatable air bag 34, and inflatable air bag 34 intercommunication has gas tube 35 and bleeder 36, and the one end that inflatable tube 35 kept away from inflatable air bag 34 is connected with pump 37, installs bleed valve 38 on the bleeder 36.
The specific implementation process is as follows: firstly, a worker pours the membrane making liquid into the barrel 4 through the liquid inlet of the barrel 4, the driving motor 8 is started, the driving motor 8 drives the stirring shaft 7 to rotate, so that the stirring blade 9 rotates, the membrane making liquid in the barrel 4 is stirred, the membrane making liquid is uniformly mixed, premixing of the membrane making liquid is realized, and partial components in the membrane making liquid are prevented from being settled.
After the driving motor 8 is started, the worker holds the handle 27 by hand, rotates the winding roller 23 clockwise, winds the non-woven fabric 28 on the winding roller 23, and simultaneously rotates the releasing roller 22 counterclockwise to release the clean non-woven fabric 28 (initially, if the non-woven fabric 28 on the workbench 2 is clean and free of dirt, the winding roller 23 does not need to be rotated to replace the non-woven fabric 28 on the workbench 2) until the clean non-woven fabric 28 is fully paved on the workbench 2. In-process, because tensioning roller 25 can move up and down in the vertical direction, consequently tensioning roller 25 can make non-woven fabrics 28 be in the state of straining all the time, and because the distance between guide roll 24 bottom and the workstation 2 equals the thickness of non-woven fabrics 28, therefore non-woven fabrics 28 can laminate in the upper surface of workstation 2, does not influence the thickness of membrane when making membrane. In addition, because the wind-up roll 23 can only rotate clockwise, and the releasing roll 22 is subjected to large friction resistance in the rotating process, after the worker stops rotating the wind-up roll 23, the non-woven fabric 28 is in a tensioned state, thereby ensuring that the film body with the preset thickness is smoothly prepared.
Then, the screw thread adjusting lever 21 is rotated to move the screw thread adjusting lever 21 downward, the slide plate 18 is pushed to slide downward, the film scraping blade 19 on the slide plate 18 is extended out of the groove 17, and the distance between the film scraping blade 19 and the non-woven fabric 28 is adjusted by rotating the screw thread adjusting lever 21 so that the distance is equal to the predetermined thickness of the film body.
And then, after the membrane-making liquid is stirred, the driving motor 8 is closed, the liquid outlet valve 11 on the liquid outlet pipe 10 is opened, the membrane-making liquid in the cylinder 4 flows into the arc-shaped overflow groove 5 through the liquid outlet pipe 10, the membrane-making liquid in the arc-shaped overflow groove 5 is gradually increased, when the membrane-making liquid overflows from the overflow port of the arc-shaped overflow groove 5, the telescopic cylinder 13 is started, the output end of the telescopic cylinder 13 pushes the cylinder 4 and the membrane scraping seat 14 to move leftwards, so that the membrane-making liquid overflowing from the overflow port dispersedly drips onto the non-woven fabric 28 on the workbench 2, and the membrane-making liquid is filtered by the filter screen 16 to remove impurities, thereby improving the. Meanwhile, the film scraping knife 19 on the film scraping seat 14 moves leftwards, so that the film forming liquid dripped onto the non-woven fabric 28 is uniformly scraped on the non-woven fabric 28, and film forming is completed.
After the membrane is prepared, the liquid outlet valve 11 on the liquid outlet pipe 10 is immediately closed, no membrane preparation liquid flows into the arc overflow groove 5, then the telescopic cylinder 13 is closed, the membrane scraping seat 14 is still, a worker rotates the thread adjusting rod 21, so that the thread adjusting rod 21 moves upwards, the sliding plate 18 slides upwards under the action of the elastic piece I20 to reset, and then the membrane scraping knife 19 moves upwards to be away from the non-woven fabric 28.
Then, the worker starts the inflator 37, the inflator 37 inflates the inflatable airbag 34 through the inflation tube 35, the inflatable airbag 34 gradually expands, and the liquid level in the water tank 3 gradually rises until the nonwoven fabric 28 and the film body on the nonwoven fabric 28 are completely submerged in the water, so that the film body is solidified in the water. After the film body is solidified, the air release valve 38 on the air release pipe 36 is opened, the air in the inflatable air bag 34 is exhausted through the air release pipe 36, the volume of the inflatable air bag 34 is reduced, the liquid level in the water tank 3 is lowered, and the non-woven fabric 28, the film body and the workbench 2 are exposed. Then, the worker dries the film body with a blower or other means, and simultaneously dries the nonwoven fabric 28, and cuts the nonwoven fabric 28 having the film body on the surface thereof after drying (the width of the nonwoven fabric 28 having the film body on the surface thereof is smaller than the width of the nonwoven fabric 28).
Finally, the staff holds handle 27, clockwise rotation wind-up roll 23, winds up old non-woven fabrics 28 to wind-up roll 23 on, releases new, clean non-woven fabrics 28 of roller 22 anticlockwise rotation release simultaneously, until clean non-woven fabrics 28 flatly lays on workstation 2 completely, can carry out the membrane of next time, easy operation, convenience improve membrane efficiency.
