Description

Connection structure of collector pipe of reverse osmosis membrane element

Technical Field

The utility model relates to a connection structure of collector pipe of reverse osmosis membrane element.

Background

Reverse osmosis membrane elements are commonly used components in water purification machines. In order to save space and facilitate use and installation, the existing reverse osmosis membrane element is a mode of spirally winding a membrane bag along a central water production pipe, and finally forms a cylindrical shape formed by a plurality of compact membrane bag layers, namely a roll type reverse osmosis membrane element. As shown in fig. 1, in the conventional connection structure of the water collection pipe of the reverse osmosis membrane element, the double-sided adhesive tape 30 is manually adhered to the central water production pipe 10 and then the membrane bag layer 20 is fixedly adhered to the double-sided adhesive tape 30 in the production process of the reverse osmosis membrane element, which has the technical defects of multiple processes, complex operation, high error rate, low efficiency, uneven adhesion and fixation, poor automation degree and high cost.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome prior art not enough, provide a connection structure of reverse osmosis membrane element's collector pipe that production efficiency is high, paste fixed more even, degree of automation is high, with low costs.

The utility model adopts the technical proposal that: the utility model discloses a central collector pipe, runner cloth, the lateral wall of central collector pipe is equipped with a plurality of water collecting hole, on the outer wall of central collector pipe in the periphery of water collecting hole is equipped with melts the joining region, the integrative integration of open end of runner cloth is fixed in melt on the joining region, the open end of runner cloth with melt and not be equipped with double faced adhesive tape and glue between the joining region, the winding of runner cloth in the outer wall of central collector pipe to form the structure that the multilayer was convoluteed.

The open end of the flow channel cloth and the fusion area are fixedly connected into a whole through ultrasonic welding fusion.

Or the open end of the flow channel cloth and the fusion area are fused and fixed in a hot-melting mode to form an integral connection.

Or the open end of the flow path cloth and the fusion area are integrally connected through chemical liquid corrosion fusion and fixation.

The utility model has the advantages that: because the utility model discloses a central collector pipe, runner cloth, the lateral wall of central collector pipe is equipped with a plurality of water collecting holes, be equipped with on the outer wall of central collector pipe in the periphery of water collecting hole and melt the district, the open end of runner cloth fuses fixedly in on the melt district integratively, do not be equipped with double faced adhesive tape and glue between the open end of runner cloth and the melt district, the runner cloth twines in the outer wall of central collector pipe to form the structure of multilayer coiling; the utility model arranges the fusion area on the outer wall of the central water collecting pipe, and fuses and fixes the open end of the runner cloth and the fusion area to form an integrated connection structure by ultrasonic welding or hot melting or liquid medicine corrosion, thereby saving the prior step of manually pasting double faced adhesive tape and realizing automatic or semi-automatic production; the event the utility model discloses production efficiency is high, paste fixed more even, degree of automation is high, with low costs.

FIG. 1 is a schematic view of a connection structure of a water collecting pipe of a conventional reverse osmosis membrane element;

fig. 2 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The first embodiment is as follows:

as shown in fig. 2, the connection structure of the water collection pipe of the reverse osmosis membrane element of this embodiment is a roll type reverse osmosis membrane element, and includes a central water collection pipe 1 and a flow channel cloth 2, the side wall of the central water collection pipe 1 is provided with a plurality of water collection holes 4, the outer wall of the central water collection pipe 1 is provided with a fusion region 3 at the periphery of the water collection holes 4, the open end of the flow channel cloth 2 is integrally fused and fixed on the fusion region 3, no double-sided adhesive and glue are provided between the open end of the flow channel cloth 2 and the fusion region 3, the flow channel cloth 2 is wound around the outer wall of the central water collection pipe 1, and a multi-layer winding structure is formed, in this embodiment, the open end of the flow channel cloth 2 and the fusion region 3 are integrally connected by ultrasonic welding, fusion.

Example two:

the difference between the connection structure of the water collecting pipe of the reverse osmosis membrane element of the embodiment and the first embodiment is that: the open end of the flow path cloth 2 and the fusion area 3 are fused and fixed in a hot-melting mode to form an integral connection.

The remaining features of this embodiment are the same as those of the first embodiment.

Example three:

the difference between the connection structure of the water collecting pipe of the reverse osmosis membrane element of the embodiment and the first embodiment is that: the open end of the runner cloth 2 and the fusion area 3 are integrally connected through chemical liquid corrosion fusion and fixation.

The utility model overcomes prior art's defect and not enough, through set up on the outer wall of central collector pipe 1 and melt joining region 3 to will through modes such as ultrasonic bonding or hot melt mode or liquid medicine corruption the open end of runner cloth 2 with melt and fuse fixed integrative connection structure of formation between the joining region 3, saved the step that the double faced adhesive tape was pasted in current manual work, can realize automatic or semi-automatization production, consequently the utility model discloses production efficiency is high, paste fixed more even, degree of automation is high, with low costs.

The utility model discloses but wide application in reverse osmosis component field.
