Embodiment 1

[0013] Such as figure 1 Shown, a kind of manufacturing method of hollow fiber membrane module is carried out according to the following steps: (1) cast one end of several hollow fiber membranes with the same length according to a known method and hollow fiber membranes are perforated, and all hollow fiber membranes Cut the second ends of the filaments to the required length; (2) place molten hot melt adhesive with a softening point of about 62°C in the container 5 and keep it warm; extend the second ends of all hollow fiber membranes into the hot melt adhesive in the container 5mm in the center, stay for 2min; after tightening the end cap 4, connect the vacuum pump 1 to vacuumize, and connect the precision vacuum gauge 2 in the middle; (3) turn off the vacuum pump and keep the pressure at -0.002Mpa; cool down until the hot melt glue solidifies; (4) then Cut off the bottom 10mm of the second end of all the hollow fiber membranes; the effect that the holes of the hollow fiber me...

Embodiment 2

[0015] Such as figure 1 Shown, a kind of manufacturing method of hollow fiber membrane module is carried out according to the following steps: (1) cast one end of several hollow fiber membranes with the same length according to a known method and hollow fiber membranes are perforated, and all hollow fiber membranes Cut the second end of the wire to the required length; (2) place the prepared epoxy resin in the container 5, extend the second end of all the hollow fiber membrane wires into the epoxy resin for 10 mm, and stay for 1 min; put the end cap 4 After tightening, connect with vacuum pump 1 for vacuuming, and connect precision vacuum gauge 2 in the middle; (3) Turn off the vacuum pump and keep the pressure at -0.001Mpa until the epoxy resin is cured; (4) Then cut off the second end of all hollow fiber membranes If the bottom is 20 mm, the hollow fiber membrane pores are completely blocked but the hollow fiber membranes are dispersed.

Abstract

The invention relates to a manufacturing method of a hollow fiber membrane component, which is characterized by comprising the following steps: (1) casting first ends of hollow fiber membrane yarns which are equally long by a conventional method, making holes in hollow fiber membrane yarns and trimming the second ends of the hollow fiber membrane yarns to a required length; (2) preparing sealant in a container, plugging the second ends of the hollow fiber membrane yarns in the sealant in the container and to a place 2 to 15 centimeters below the surface of the sealant, and vacuumizing from the first end; (3) closing a vacuum pump and maintaining the pressure between 0.001 and 0.0005MPa till the sealant is solidified; and (4) cutting 5 to 20 millimeters off from the bottom of the second ends of the hollow fiber membrane yarns, and manufacturing the hollow fiber membrane component. In the hollow fiber membrane component manufactured by the method, all of the hollow fiber membrane yarns of an upper cast end are cast together normally and have holes, all of the holes in the hollow fiber membrane yarns of a lower cast end are plugged, and the hollow fiber membrane yarns are separated rather than adhered together.

Description

technical field [0001] The invention relates to membrane separation technology, in particular to a method for manufacturing a hollow fiber membrane module. Background technique [0002] Membrane separation technology has been widely used in water treatment, fluid concentration and separation, impurity removal and purification, etc. However, the existing hollow fiber membrane modules have deficiencies such as strict pretreatment requirements, dead angles in operation, difficulties in hoisting and cleaning, tensile deformation and breakage. The applicant has developed a membrane module with single-ended plugging and free swing. It can be used in all occasions where the current hollow fiber membrane is applicable, and is especially suitable for environments with poor raw water quality. However, the currently known manufacturing methods and patented manufacturing methods, such as Asahi Kasei's application number 200710196205.1 "Manufacturing Method of Hollow Fiber Membrane Filt...
