Description

Technical Field

[0001] This utility model relates to the field of reverse osmosis membrane technology, specifically a reverse osmosis membrane device. Background Technology

[0002] During long-term operation and maintenance, osmotic membrane devices have revealed the following common problems: Replacing membrane elements is difficult; traditional membrane housings often use a two-end fixed end cap structure, requiring the entire collection pipe to be removed and the end cap bolts loosened section by section during disassembly, which is difficult to perform on-site due to space constraints. Furthermore, after wastewater enters the membrane housing, it does not effectively collect on one side of the reverse osmosis membrane cartridge, resulting in low wastewater entry efficiency and affecting wastewater treatment performance. Extensive research has been conducted on these issues. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a reverse osmosis membrane device that can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A reverse osmosis membrane device of this utility model includes multiple membrane shells, a water collection pipe is fixedly installed in each membrane shell, a shell cavity is provided inside each membrane shell, multiple reverse osmosis membrane tubes are sleeved on the outer surface of the water collection pipe, the reverse osmosis membrane tubes are located in the shell cavity, and an outlet pipe is provided between the membrane shells. The feature is that a water inlet component is provided on the right side of each membrane shell to allow wastewater to enter from the side of the reverse osmosis membrane tube, and an outlet pipe is provided on one side of the water collection pipe.

[0005] In a further technical solution, two bases are fixedly installed at the bottom of the membrane shell.

A pipe joint structure for diffusing wastewater to the side of the reverse osmosis membrane is provided between the bent pipe and the reverse osmosis membrane cartridge. A blocking structure is also provided inside the membrane housing to block and collect wastewater on the side of the reverse osmosis membrane cartridge.

[0009] In a further technical solution, a hexagonal nut is fixedly provided on the right end face of the end cap.

[0010] A further technical solution includes a pipe joint structure comprising a fixed sleeve fixedly disposed on one side of the water collection pipe, an end pipe fixedly disposed on one side of the bend, the end pipe being inserted into the fixed sleeve, and a plurality of leakage holes being disposed inside the bend, the leakage holes being connected to the shell cavity.

[0011] A further technical solution is that the barrier structure includes a horn-shaped component, which is sleeved on the outer surface of the reverse osmosis membrane cartridge, and the horn-shaped component is abutted against the membrane shell by the end cap.

[0012] A further technical solution includes a horn-shaped component comprising a cylindrical portion, a conical portion fixedly disposed on one side of the cylindrical portion, a flange portion fixedly disposed on one side of the conical portion, a groove disposed inside the membrane housing, the flange portion abutting against the groove, and the cylindrical portion sleeved on the outer surface of the reverse osmosis membrane cartridge.

The pure water is discharged to the external space through the collection hole, pipe cavity and water collection pipe, and the concentrated water is discharged to the external space through the water outlet pipe.

[0015] Second, through the structural design of the water inlet component, after the flange is removed, the bend, hexagonal nut and end cap can be rotated and separated from the membrane housing.

This structure can also make the two ends of the water collection pipe snapped together, which is more stable and makes it easier to place the inner ring sealing ring in the center to avoid skewing.

[0042] The water inlet assembly uses a threaded end cap, which can be disassembled to directly remove the horn-shaped component and the reverse osmosis membrane cartridge, enabling quick replacement.
