Embodiment
[0034] First remove the receiving ring body 2 and the pressing cover 1, insert the corresponding membrane wires into all the pins of the removal mold body 3, then install the receiving ring body 2, insert three straight pipes, and press the pressing cover 1 with Tighten, pour the epoxy glue, after curing, remove the receiving ring body 2 and the compression cover 1, put 8 nuts into the grooves corresponding to the removal mold body, and use the bolts to move the removal mold body 3 upward in parallel , to complete the separation of the pins and the epoxy glue on the root pin mold body 4 . Then, using a flat-blade screwdriver or similar structure, lightly prying can complete the separation of the epoxy colloid and the removal mold body 2 .

The invention relates to a casting structure for hollow fiber column type membrane. The casting structure comprises a compression cover, a receiving ring body, a removal die body, a root needle die body and a bottom surface die body which are sequentially arranged in parallel from top to bottom, wherein the removal die body is provided with a nut removal hole; the nut removal hole is internally provided with a preset nut; a bolt is screwed into the nut to apply a reverse removal force of an action force to the root needle die body below the bolt. According to the casting structure for the hollow fiber column type membrane, the using cost of customers can be greatly reduced, the membrane filament encapsulation efficiency can be improved, membrane filaments are arranged strictly and uniformly and can be, that is, cast partially or in multiple times, and thus the casting process is more flexible, and no centrifuge is needed to be used; therefore, the casting structure is applicable to more occasions to substitute for an existing casting technology; in the meantime, the subsequent membrane housing design is more flexible; the bolt is adopted to apply a demoulding force to the root needle die body; the casting structure is simple in structure design; the demoulding force is easy to adjust; the demoulding process is safe and reliable.
Description
technical field [0001] The invention relates to the field of pouring columnar fiber membrane shells, in particular to a pouring structure of a hollow fiber columnar membrane. Background technique [0002] All column membrane modules on the market are cast by centrifuge, epoxy glue is placed above the cylindrical membrane shell, and the glue is injected into both ends through the centrifuge. The hollow fiber membrane and membrane shell are cured simultaneously. [0003] But this approach has several disadvantages: [0004] 1. Because the membrane filaments were not neatly arranged and each filament was fixed before, the final distribution of the membrane filaments was uneven. [0005] 2. Since the centrifuge must be used for integral molding, the final column membrane cannot be disassembled. SUMMARY OF THE INVENTION [0006] The invention provides a pouring structure of hollow fiber column membrane, which can greatly reduce the customer's use cost, improve the membrane f...
