Problems solved by technology

The advantage of the vertical static glue filling method is that it is easy to operate, but there are also many disadvantages: for example (1) air bubbles are easily mixed in the glue during the glue filling process, and there are areas where there is no glue filling between the membrane filaments, resulting in water leakage at the end seal, The qualified rate of quality is reduced; (2) capillary phenomenon (glue climbing) cannot be avoided, the height of glue filling and the amount of glue used are greatly increased, which not only affects the filtration performance, but also increases the production cost. In severe cases, the components are scrapped; (3 ) During the standing process, the membrane filaments at the end seals are prone to breakage, which affects the water outlet of the membrane filaments and the appearance of the product
[0005] Although the existing horizontal and horizontal centrifugal glue filling has solved some disadvantages of the vertical static glue filling, such as the air bubbles in the glue are discharged, and the capillary phenomenon (glue climbing) can also be avoided, but it also has its own shortcomings, such as (1 ) needs to be filled with glue in the middle tank, and the glue tank needs to be cleaned frequently, which is labor-intensive and time-consuming; (2) the rubber hose connecting the glue tank to the product needs to be replaced frequently. Frequent replacement, the connection part is easy to fall off and cause flying glue; (3) Because it is centrifugal glue filling, it cannot guarantee the same amount of glue filling for all products

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, this technical scheme is described in further detail:

[0024] The specific steps of the method for manufacturing a hollow fiber membrane module using hydrostatic glue filling and centrifugation in this embodiment are as follows:

[0025] (1) Start the glue filling machine, and put the polyurethane two-component glue raw materials into the main agent barrel and curing agent barrel of the glue filling machine respectively, and adjust the valve to control the glue output in advance so that the weight ratio is 5:1 ~5:3 mix and spray glue through the mixing nozzle, after finishing, wait for glue pouring;

[0026] (2) For the end cover type membrane shell, apply the release agent on the end cover 2, fasten it on one end of the end seal required by the membrane shell 1, and then place it vertically on the glue filling machine console Carry out glue filling (for the integral membrane shell, omit the step of adding the end cover,...

Abstract

The invention discloses a method for centrifugally manufacturing a hollow fiber membrane module by static pressure glue filling. The specific steps are as follows: (1) Place a pre-installed end cap type membrane shell or an integral membrane shell vertically on the glue filling On the operating table, the upper port is facing the glue pouring nozzle, and inject special glue, move it to the working table and stand it upright for 2 to 4 minutes. (2) Insert the hollow fiber membrane tow that has been end-sealed with plugging glue in advance. Fill the membrane shell with special glue, and put it vertically into the centrifugal equipment; (3), start the centrifugal equipment, and under the action of centrifugal force, the membrane module will change from a vertical state to a horizontal state to cure the end seal. , take out the membrane module; (4), cut the hollow fiber membrane tow flat. In this method, plugging glue is used to seal the membrane pores, and a single membrane shell is filled with glue, and multiple membrane modules are centrifuged to effectively control the amount of glue filled and the time of centrifugation.

Description

technical field [0001] The invention belongs to the technical field of membrane separation, and relates to a method for manufacturing a hollow fiber membrane module, in particular to a method for manufacturing a hollow fiber membrane module by static pressure glue filling and centrifugation. Background technique [0002] Membrane separation technology is a separation technology widely used in solution separation, concentration and purification. It uses a membrane with selective permeability as the separation medium. The membrane wall is densely covered with micropores. The raw liquid passes through one side of the membrane under a certain pressure. Retention, so as to achieve the purpose of material separation and concentration. The membrane separation process is a dynamic filtration process. The macromolecular solute is blocked by the membrane wall and flows out of the membrane module with the concentrated solution. The membrane is not easy to be blocked and can be used co...
