The invention discloses an anti-blockage coating device for hollow fiber membrane spinning. The anti-blockage coating device comprises a membrane shell, wherein hollow fiber membrane silk is equidistantly distributed in the membrane shell; the outer wall of one end of the hollow fiber membrane silk is sleeved with an epoxy resin end seal; a liquid inlet hole is formed at the middle of the outer wall of one end of the membrane shell; a liquid inlet pipe is welded on the inner wall of the liquid inlet hole; a stock solution is injected into the liquid inlet pipe; a liquid discharge hole is formed in the outer wall of the other end of the membrane shell; a liquid discharge pipe is welded on the inner wall of the liquid discharge hole; a concentrate is contained in the liquid discharge pipe; aliquid outlet pipe is welded on the outer wall of one side of the top of the membrane shell. According to the anti-blockage coating device disclosed by the invention, since the membrane shell has a shaking action, pipeline blockage is prevented during hollow fiber spinning processing, normal operation of the processing is guaranteed, the efficiency of the hollow fiber spinning processing is improved, the device stability in shaking is guaranteed, and some loss caused by excessive shake is avoided.
Description
technical field [0001] The invention relates to the technical field of hollow fiber membranes, in particular to a coating device for hollow fiber membrane spinning which avoids clogging. Background technique [0002] Hollow fiber membrane (hollow fiber membrane) looks like a fiber-like, self-supporting membrane. The hollow fiber membrane is made of polysulfone and dimethylacetamide as raw materials to process into a hollow fiber filament, and then divided by a high-permeability polymer, which has selective permeability characteristics. Since water vapor, hydrogen, ammonia and carbon dioxide permeate quickly, while methane, nitrogen, argon, oxygen and carbon monoxide permeate slowly, so that the fast permeating and slow permeating are separated. The outer diameter of the hollow fiber is usually 500-600pum and the inner diameter is 200-300pum. It is made into a fiber bundle of 3-6 meters and put into a high-pressure metal shell. One end of the fiber bundle is sealed, and the ...
