The device for preparing the fiber-reinforced hollow fiber membrane comprises a feeding roller of a fiber-reinforced weaving pipe, a core liquid dipping tank, a guide roller, a cast membrane liquid preparation system, a coating die head, a coagulating bath tank and a winding roller. The device for preparing the fiber-reinforced hollow fiber membrane is characterized in that the surface of the fiber weaving pipe passing through a dipping core liquid is covered with a cast membrane liquid fully and uniformly by virtue of the coating die head, then the fiber weaving pipe is formed after entering the coagulating bath, and finally is wound, thereby obtaining a fiber-reinforced hollow fiber separating membrane with uniform degree of hollowness and wall thickness.
Description
Technical field
The present invention relates to the doughnut membrane preparation device, be specially a kind of device for the preparation of fibre-reinforced high strength hollow fiber separating film.
Background technology
Hollow-fibre membrane is a kind of in the diffusion barrier.Greatly, do not need plurality of advantages such as backing material, production technology are simple, preparation facilities miniaturization to be used widely in the membrane separation technique field because of its loading density.
In the preparation of hollow-fibre membrane, adopt dry-wet spinning, dry spinning usually, and melt spinning-numerous methods such as stretching.The hollow-fibre membrane of the different separating properties of these preparation method's gained can satisfy fields such as general chemical separating, enrichment, purification and pure water manufacturing to the requirement of film-strength.But at the abominable sewage treatment area of environment, particularly in the application of membrane bioreactor (MBR), because it will be subjected to the impact of aeration usually, its intensity often can not be satisfactory.Adopt the doughnut film strength of the thermally induced phase separation preparation of gel spinning to be further enhanced, but also have a certain distance with people's desired value.
In the manufacture process of hollow-fibre membrane, be matrix with the fortifying fibre, can prepare the high strength hollow-fibre membrane.But accomplish to add core liquid equably at hollow space, and all there is certain difficulty in the control of the uniformity of hollow-fibre membrane wall thickness.
Summary of the invention
At the deficiencies in the prior art, the technical problem to be solved in the present invention is, designs a kind of preparation facilities of fibre-reinforced hollow-fibre membrane, make after the shaping fiber reinforcement hollow-fibre membrane wall thickness evenly, stable, when improving the doughnut film strength, guarantee the infiltration quality of product.
The scheme that the present invention solves the technical problem of described fiber reinforcement doughnut membrane preparation device is: design a kind of preparation facilities, comprise fortifying fibre braided tube feeding roller, core liquid dipping tank, deflector roll, casting solution preparation system, apply die head, coagulating tank, take up roll, the netted tubule direct impregnation that it is characterized in that fortifying fibre is woven is in the core liquid bath, enter casting solution coating die head vertically downward after making it suction core liquid, because the freezing action of core liquid, casting solution and fiber braided tube contact portion are progressively solidified, no longer flow to core, to ensure its hollow structure; Leave the fortifying fibre braided tube that casting solution is evenly overworked on surface that casting solution applies die head, continue to enter vertically downward coagulating bath, coagulating agent in the coagulating bath is to the casting solution diffusion on braided tube surface, solvent in the casting solution on braided tube surface spreads to coagulating bath, along with constantly carrying out of double diffusion process, the fiber reinforcement hollow-fibre membrane is shaped gradually, and reeling finally by up-coiler obtains fibre-reinforced hollow-fibre membrane; Casting solution is provided by the common casting solution compounding system that dissolution kettle, filter, pump seat, measuring pump etc. constitute.
Described coating die head is made of two critical pieces, and one of them parts has occupied top and the core of die head, and the fiber braided tube that suctions core liquid passes from top to bottom; Another parts have occupied bottom and the outside of die head, the casting solution for preparing enters from side opening, at first arrive enough big cylindrical cavity---the dynamic storage areas of casting solution that constitute between two parts, flow into downwards subsequently and be full of the annulus slit that forms between two parts, this slit begins one section for isometrical, annulus slit diameter is progressively restrained subsequently, and the cross-sectional area of cylindrical cavity is 2～5 times of maximum annulus slit cross-sectional area.Last casting solution evenly sprays to the fiber braided tube that is in the center at coating die head exit place, makes its surface evenly overwork casting solution.
Compared with prior art, the braided tube that the present invention adopts impregnated in the core liquid supply method of core liquid bath, and the coating of the casting solution in device die head can make the surface of fortifying fibre braided tube evenly overwork casting solution, hollow-fibre membrane Thickness Distribution after the shaping is even, for the raising of product quality provides reliable assurance.
