Bidirectional hot working process for hollow fiber membrane lining pipe

Abstract

The invention relates to the technical field of fiber membrane lining tubes, in particular to a bidirectional hot working process for a hollow fiber membrane lining pipe, which comprises a heating mechanism and a driving mechanism, the heating mechanism comprises a workbench, a hollow hot copper rod is fixedly connected in the workbench, a porcelain eye is fixedly connected to the lower surface of the hollow hot copper rod, and a steel ball is movably connected to the interior of the porcelain eye, a core rod is fixedly connected to the outer surface of the steel ball, the driving mechanism comprises a fixing block, and an adjusting block is movably connected to the outer surface of the fixing block. When an ejector rod slides downwards in a limiting sleeve, a protruding block exerts pushing force on a protruding plate, the protruding plate is arranged in a protruding mode, at the moment, the protruding plate pushes a connecting column to slide towards the interior of a fixing shell, at the moment, the connecting column exerts extrusion force on a liquid storage bag, and the liquid storage bag is stressed to extrude out marking liquid in the liquid storage bag. And a connecting pipeline is sprayed to the deformed position of the lining pipe, so that later searching by workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of fiber membrane lining pipes, in particular to a bidirectional thermal processing process for hollow fiber membrane lining pipes. Background technique [0002] Membrane separation technology is a separation technology widely used in the separation, concentration and purification of solutions or gaseous substances. The membrane wall is densely covered with micropores, the stock solution passes through one side of the membrane under a certain pressure, the solvent and small molecular solutes pass through the membrane wall to become the filtrate, and the macromolecular solutes are retained by the membrane to achieve the purpose of material separation and concentration. Hollow fiber membrane is an important form of separation membrane. Hollow fiber membrane refers to a membrane that looks like a fiber (so it is also called "membrane filament") and has a self-supporting effect. The hollow fiber membrane is ma...

Problems solved by technology

However, the existing technology can only iron the outer wall of the lined pipe (by machine pulling through the hollow hot copper rod), but cannot iron the inner wall of the lined pipe

The reason is that the length of the liner pipe is long (single length can reach several thousand meters) and the diameter of the pipe is small. If the mandrel with heating function is placed inside the liner pipe, it is difficult to achieve There is such a long-distance relative movement with the liner, so there is no effective ironing process for the inner wall of the liner in this field
