Problems solved by technology

[0003] The center tube of the spiral-wound reverse osmosis membrane element in the prior art has a small diameter and a long length. When forming, it is necessary to pull the core from both ends in the axial direction. It is difficult to pull the core, resulting in a central The tube production efficiency is low; when the center tube also includes positioning parts for auxiliary rolled film arranged at both ends of the effective tube body, the overall length of the center tube is further increased, and core pulling is more difficult

Abstract

The invention discloses a water outlet pipe and a water outlet pipe film coiling tooling, wherein the water outlet pipe comprises a pipe body and two positioning parts; the two positioning parts are connected with the two ends of the pipe body; each positioning part is provided with a through hole in butt joint with an inside pipeline of the pipe body; the through hole extends in the axial direction of the pipe body; the hole diameter of the through hole is greater than the inner pipe diameter of the pipe body. By using the technical scheme, the water outlet pipe forming core pulling difficulty can be reduced.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis water purification, in particular to a water outlet pipe and a water outlet pipe rolling film tooling. Background technique [0002] The spiral-wound reverse osmosis membrane element is a commonly used element in water treatment technology. It has a central tube with multiple holes and alternately stacked multi-layer reverse osmosis membranes and diversion nets wound on the central tube. The central tube is connected with the two ends of the housing through connectors. When in use, the raw water enters the shell from one end of the shell, and under the action of pressure, part of it passes through the reverse osmosis membrane to form water with a lower concentration. After entering the central tube, it flows out from one or both ends of the central tube. This part of water can be called It is used as produced water or pure water; the other part flows out from the other end of the shell, w...
