Abstract
Description
Technical Field
[0001] This utility model relates to the field of reverse osmosis membrane technology, and in particular to a reverse osmosis membrane housing assembly. Background Technology
[0002] Reverse osmosis membrane technology is widely used in water treatment and other fields. As a key component that carries the reverse osmosis membrane element and provides it with a stable working environment, the performance of the reverse osmosis membrane housing directly affects the operation of the entire reverse osmosis system.
[0003] Traditional reverse osmosis membrane housings have revealed numerous problems in practical use. On one hand, regarding water flow distribution, the flow path within the housing lacks proper design, easily leading to uneven flow velocity and stagnant zones, resulting in low flow efficiency and failing to fully utilize the filtration performance of the reverse osmosis membrane, thus reducing the effective utilization rate of water resources. On the other hand, sealing the membrane housing ports has always been a challenging problem in the industry. Existing sealing structures at the membrane housing ports are prone to failure after prolonged exposure to high-pressure water flow, leading to water leakage. This not only wastes water resources but may also damage surrounding equipment and the environment. Furthermore, traditional membrane housings also have insufficient pressure resistance; when the system operating pressure is high, the membrane housing is at risk of rupture, seriously affecting the safety and stability of the system operation. Therefore, we propose a reverse osmosis membrane housing assembly to solve this problem. Utility Model Content

A carbon fiber winding layer 6 is fixedly sleeved on the outer side of the membrane housing body 1. Threaded sleeves 4 are provided at the top and bottom of the outer side of the membrane housing body 1. Connecting plates 15 are provided at the top and bottom of the membrane housing body 1. Pads 13 are fixedly installed on the corresponding sides of the upper and lower connecting plates 15. Baffles 14 are fixedly installed on the corresponding sides of the upper and lower pads 13. Top plates 10 are fixedly installed on the opposite sides of the upper and lower connecting plates 15. Limiting rods 8 are fixedly installed on the left and right sides of the corresponding sides of the upper and lower connecting plates 15. Annular plates 7 are fixedly installed on the outer side of the corresponding sides of the upper and lower connecting plates 15. The carbon fiber winding layer 6 is made of multiple layers of tightly wound carbon fiber filaments and is tightly bonded to the outer wall of the membrane housing body 1 using a high-performance resin adhesive to enhance the pressure resistance of the membrane housing.
[0018] In this embodiment, there are four sets of spiral guide channels 5, which are arranged in a ring array. The inner wall of the threaded sleeve 4 is rotatably connected to the outer side of the membrane body 1. The outer side of the annular plate 7 is threadedly connected to the inner side of the threaded sleeve 4. Sealing gaskets 9 are provided at the top and bottom of the membrane body 1. One side of the limiting rod 8 passes through the sealing gasket 9 and extends into the interior of the membrane body 1. The limiting rod 8 can limit the top plate 10, thereby improving the installation stability of the top plate 10. The sealing gasket 9 is made of high pressure resistant and corrosion resistant rubber material to enhance the sealing performance of the connection.
[0019] In this embodiment, the pad 13 is conical, and an injection groove 12 is formed between the outer side of the pad 13 and the membrane shell body 1. An injection hole 11 adapted to the injection groove 12 is opened through one side of the top plate 10 and the connecting plate 15. An inlet 2 is fixedly connected to the top right side of the membrane shell body 1, and an outlet 3 is fixedly connected to the bottom right side of the membrane shell body 1.

[0020] In this embodiment, during use, the mold core is first placed inside the membrane housing body 1, then the sealing gaskets 9 are placed at the top and bottom of the membrane housing body 1 respectively, and then the limiting rod 8 is inserted into the membrane housing body 1. By rotating the threaded sleeve 4 in the forward direction, the threaded sleeve 4 drives the screwed annular plates 7 to move closer to each other, fixing the top plate 10. Then, glue is injected through the glue injection hole 11, so that the glue flows into the glue injection groove 12 to achieve glue self-locking seal. The water to be treated enters the membrane housing body 1 from the water inlet 2. Under the guidance of the spiral guide channel 5, the water flow forms a spiral flow in the membrane housing body 1, which optimizes the water flow distribution, improves the flow efficiency, and enables the reverse osmosis membrane to play a more complete filtration role. The carbon fiber winding layer 6 on the outer wall of the membrane housing body 1 enhances the pressure bearing capacity of the membrane housing body 1, ensuring the safe and stable operation of the membrane housing body 1 under high pressure. The treated water flows out from the water outlet 3.
