Abstract

The invention discloses a method and apparatus for manufacturing a hollow fiber membrane module. The method comprises: S1, cleaning of the membrane shell before manufacturing: tap water and a certainamount of cleaning agent are added into a first cleaning tank of an ultrasonic cleaning device to prepare a cleaning liquid with a certain concentration, pure water is added into a second cleaning tank, and the component inner shell, the outer shell and the end cover are put into the first cleaning tank for ultrasonic cleaning, which relates to the technical field of water treatment membrane separation. The method and apparatus for manufacturing a hollow fiber membrane module, two steel pipes and plastic ropes are used to fix one end of the membrane filament beam that that membrane filament ofeach partition can maintain the softness of the membrane filament after finishing, so as to prevent the membrane filament from twisting in the membrane shell, the assembly manufacturing equipment isselected to cut and block the membrane filament beam which can realize the suspension fixation and transfer of the assembly, realize semi-automatic cutting and blocking, the tie tape is fixed at the lower end with vice, and cut the membrane filament horizontally along the tie tape with wallpaper knife or other tools, which can improve the flatness of the membrane filament section.

Description

technical field [0001] The invention relates to the technical field of membrane separation for water treatment, in particular to a method and equipment for manufacturing hollow fiber membrane modules. Background technique [0002] Ultrafiltration membrane separation technology is a high-tech separation technology at the molecular level developed in recent years. It separates particulate matter from fluid and dissolved components. The typical pore size of the ultrafiltration membrane is between 0.01 and 0.001 microns, and it has a very high removal rate for bacteria and most germs, colloids, and sludge. The smaller the nominal pore size of the membrane, the higher the removal rate. Hollow fiber membrane is one of the most important types of ultrafiltration membrane, which is capillary-shaped and spun by spinning. Its inner or outer surface is a dense layer, or active layer, and the inner part is a porous support. The dense layer is densely covered with micropores, and the...
