Production device of hollow fiber membrane element and method thereof

Abstract

The invention discloses a production device of hollow fiber membrane element and a method thereof. The production device comprises a pre-drying element, a locating element and a packaging element which are sequentially arranged in a membrane fiber forward direction, wherein the pre-drying element is a closed element, and the locating element is communicated with the packaging element; the production device further comprises a control part which is respectively connected with the pre-drying element, the locating element and the packaging element. According to a production method provided by the invention, the initial drying of the membrane fiber, the membrane fiber drying of a packaging section and an online membrane fiber casting can be respectively completed by the pre-drying element, the locating element and the packaging element, and a spinning head can be directly and automatically casted and packaged through the rinsed membrane fiber, so as to realize a process from fiber distribution to casting and cutting head, realize the automatic production process and reduce the dependence to manual factors caused by the process; furthermore, the produced membrane elements have the characteristics of being regular to arrange and high in membrane fiber volumetric proportion, and the quality can be significantly improved.

Description

technical field [0001] The invention relates to the field of production of hollow fiber filter elements, in particular to a production device and method for hollow fiber membrane elements. Background technique [0002] Membrane technology (especially hollow fiber membrane) has become the most promising and fastest-growing water treatment technology as a resource for sewage, whether it is MBR membranes used in sewage treatment plants, or pressurized membranes used in industrial and raw water plants. Type membrane, its annual demand can reach the level of tens of millions of square meters. [0003] The production process of hollow fiber membrane elements mostly adopts the method of manual intervention (manual assembly), which requires a large space, a long production cycle, and high labor costs. Due to the existence of manual intervention, it is inevitable that there will be low yields and large fluctuations in product quality. Defects, and during the membrane casting glue pr...
