Problems solved by technology

Its disadvantages are: first, the strength of the epoxy resin end ring formed by the package is low
In addition, the inner cylindrical surface of the annular boss 3b presses the hollow fiber membrane tow 1 tightly, loosening and tightening when it exists, and forming a package after packaging. figure 2 The shape of the concave spherical surface with a low middle and high edge is shown, and the packaging of the middle part is not in place, which reduces the working strength of the end of the hollow fiber membrane tow and cannot meet the needs
Second, only one end of the epoxy resin end ring can be packaged at a time, and a hollow fiber membrane tow 1 needs to be packaged twice, which reduces work efficiency

Embodiment 1

[0017] Embodiment 1, the step of glue injection is as follows:

[0018] 1. Put the ends of the hollow fiber membrane tow 1 into two molds 4 respectively;

[0019] 2. Glue injection preparation: use commercially available finished AB two-component epoxy resin glue, put the mixed AB two-component epoxy resin glue into two glue tanks, and use hoses to remove the glue from the glue tanks. The mouth is connected with the upper glue inlet 4a of the mold 4, and the glue outlet of the glue tank is about 20cm higher than the upper glue inlet 4a of the mold 4. Fix the two glue tanks on the bracket at the center of the centrifuge workbench, and place the hollow fiber The mold 4 at both ends of the membrane tow 1 is fixed on the edge of the centrifuge workbench, with the upper glue inlet 4a facing upwards; the volume of the epoxy resin glue in the glue tank is equal to the volume of the epoxy resin glue required by the epoxy resin end ring 2 1 times;

Embodiment 3

[0025] Embodiment 3, the step of glue injection is as follows:

[0026] 1. Put the ends of the hollow fiber membrane tow 1 into two molds 4 respectively;

[0027] 2. Glue injection preparation: use commercially available finished AB two-component epoxy resin glue, put the mixed AB two-component epoxy resin glue into two glue tanks, and use hoses to remove the glue from the glue tanks. The mouth is connected with the upper glue inlet 4a of the mold 4, and the glue outlet of the glue tank is about 40cm higher than the upper glue inlet 4a of the mold 4. Fix the two glue tanks on the bracket at the center of the centrifuge workbench, and place the hollow fiber The mold 4 at both ends of the membrane tow 1 is fixed on the edge of the centrifuge workbench, with the upper glue inlet 4a facing upwards; the volume of the epoxy resin glue in the glue tank is equal to the volume of the epoxy resin glue required by the epoxy resin end ring 2 1.2 times;

Abstract

The invention belongs to an air separation technology, and relates to an improvement of a glue filling method of a hollow fiber film silk bundle end socket in packaging. The glue filling method is characterized by comprising the steps of respectively placing end sockets of the two ends of a hollow fiber film silk bundle (1) into two moulds (4), carrying out glue filling preparation on the two moulds, and carrying out centrifugation glue filling glue filling on the hollow fiber film silk bundle. The improved glue filling method of the hollow fiber film silk bundle end socket in the packaging provided by the invention has the advantage that the intensity of an epoxy resin end ring and the packaging work efficiency are improved.

Description

technical field [0001] The invention belongs to the air separation technology and relates to the improvement of the glue injection method when the end of the hollow fiber membrane tow bundle is packaged. Background technique [0002] For the structure of hollow fiber membrane tow ends after encapsulation, see figure 1 , where 1 is the hollow fiber membrane tow and 2 is the epoxy resin end ring. The epoxy resin end ring 2 bonds the membrane filaments at the end of the hollow fiber membrane bundle 1 into a whole. At present, the glue injection method when the end of the hollow fiber membrane tow is packaged is: see figure 2 , the steps of glue injection are as follows: first, installation: put the ends of one end of the hollow fiber membrane tow 1 into two molds 3 respectively. The left and right half molds are connected as a whole, and the left and right half molds are combined to form a cylinder with a closed lower end. There is a lower glue inlet 3a in the center of the...
