Embodiment 1
[0062] like figure 1 and 2 As shown, this embodiment provides a variable-diameter spinneret, including a central circular tube 11, a middle circular tube 12 and an outer cavity 13 that are sleeved in sequence, and a first drive mechanism that drives the central circular tube 12 to move vertically up and down 14. The bottoms of the central circular tube 11, the middle circular tube 12 and the outer cavity 13 are flush.
[0063] In this embodiment, the top of the middle circular pipe 12 is sealed, and the upper part is provided with a feeding port 121 for feeding.
[0064] In this embodiment, the middle circular tube 12 protrudes out of the central circular tube 11 and the outer cavity 12 , and the first driving mechanism 14 includes a first gear 141 arranged on the protruding part of the middle circular tube 12 , and the first gear is connected to the first gear 141 . The meshed second gear 142 and the first motor 143 that drives the second gear to move, the first motor 143 d...
Embodiment 2
[0069] On the basis of implementation 1, this embodiment refers to image 3 , 4 and 5, a processing device for hollow fiber membrane tow is also provided, including the variable diameter spinneret 1 in Example 1, the first feeding mechanism 2 for feeding the central circular tube 11, and the The second feeding mechanism 3 for feeding the intermediate circular tube 12, the collecting structure 4 for collecting the membrane filaments spun by the diameter spinning nozzle 1, the cutting of the membrane filaments for cutting the membrane filaments on the collecting structure into the membrane filament segment A mechanism 5 and an automatic strapping machine 6 for strapping the film filaments.
[0070] In this embodiment, the first feeding mechanism 2 includes an inner coagulation bath 21 that communicates with the central circular tube 11 ; The flow meter 22, the first pump 23 and the first valve 24, the first feeding mechanism can realize the continuous feeding of the central tu...
Embodiment 3
[0081] refer to Image 6 , this embodiment also provides a processing device for a hollow fiber membrane module, including the processing device for the hollow fiber membrane tow in Example 2, a membrane module 7 for accommodating the membrane tow, a glue dispensing mechanism 8 and a device for cutting the membrane tow The second shearing mechanism 9 of the bundle.
[0082] Specifically, the hollow fiber membrane tow is placed in the membrane module, and the glue is dispensed by a glue dispenser, and then the membrane yarn ends at both ends of the bundling belt are cut by the second shearing structure to obtain the hollow fiber membrane module.
[0083] In this embodiment, the membrane module 7 includes a membrane module housing 71 with both upper and lower openings, sealing plates 72 detachably arranged on both ends of the membrane module housing 71, and sleeved on the upper and lower end surfaces of the membrane module housing 71. Assembly head 73 .
[0084] Specifically, ...
