Production method and device for woven hollow fiber membranes

Abstract

The invention discloses a production method for woven hollow fiber membranes. The production method comprises a step of winding the woven membranes, wherein the membranes can be rolled up, and simultaneously, a step of packaging the membranes through a hot melt adhesive is added. The woven membranes are packaged through the hot melt adhesive before being rolled up, so that the packaging step is convenient to implement, and the purposes of reducing the process complexity and the labor consumption of the packaging step can be realized. The invention further discloses a production device for the woven hollow fiber membranes. The production device comprises a membrane reeling roller, a transmission roller, a membrane pressing roller and a membrane unreeling roller, wherein the membrane pressing roller flattens the woven membranes and generates certain tension; the membrane reeling roller is used for reeling membrane wires; and a hot melt adhesive machine for packaging the membranes through the hot melt adhesive is arranged between the membrane reeling roller and the membrane unreeling roller, so that the membranes can be packaged through the hot melt adhesive by virtue of the hot melt adhesive machine when being reeled by the membrane reeling roller.

Description

technical field [0001] The invention relates to the technical field of filter membrane production, and more specifically relates to a production method and device for a woven hollow fiber membrane. Background technique [0002] Hollow fiber membrane is a separation membrane of selectively permeable hollow fiber with micropores in the fiber wall, and its micropore size is on the order of nanometers to micrometers. [0003] At present, the common PVC, PP, PTFE, PVDF, PS or PES hollow fiber membranes in the market need to be wound up first, and then centrifugally filled and packaged. In the prior art, the film filaments are firstly wound up, which leads to complicated operation process and low degree of automation for the subsequent glue potting and encapsulation operation, which results in large manpower consumption. [0004] To sum up, how to solve the problem of complex hollow fiber membrane production process has become an urgent problem to be solved by those skilled in th...
