Abstract

The invention relates to a variable-diameter spinneret, a hollow fiber membrane tow processing device and a membrane module processing device. The variable-diameter spinneret comprises a central circular tube, a middle circular tube and an outer cavity which are sequentially arranged in a sleeving mode, and a first driving mechanism for driving the middle circular tube to vertically move up and down, and the bottom of the central circular tube, the bottom of the middle circular tube and the bottom of the outer cavity are flush. A membrane filament obtained through regulating the position of the middle circular tube by the variable-diameter spinneret comprises membrane filament heads with a large diameter at the two ends and a membrane filament middle section with a small diameter, and theporosity of the membrane filament middle section can be regulated by controlling the diameter ratio of the membrane filament heads to the membrane filament middle section in the subsequent bundling and assembling process of membrane modules in order to achieve the regular arrangement of the membrane modules with any filling density.

Description

technical field [0001] The invention belongs to the technical field of hollow fiber membrane modules, and in particular relates to a variable diameter spinneret, hollow fiber membrane tow and a processing device for membrane modules. Background technique [0002] Membrane separation technology is widely used in seawater desalination, water treatment, biomedicine and many other modern industrial technology fields. Membrane module is a key component of various membrane separation industries, and its processing technology and related equipment have important economic value. However, at present, the processing technology of modules using hollow fiber membranes mainly has defects such as non-mechanization, low filling density, and poor consistency of module performance. With the increasing application of membrane separation technology, higher requirements are placed on the automation of membrane module processing and module packing density. [0003] Chinese invention patent 104...
