[0002] The industrial reverse osmosis single filter membrane shell is the core component of the reverse osmosis system and is a pressure vessel for installing the reverse osmosis membrane. There are some shortcomings in the daily use and maintenance process. The end caps on both sides of the membrane shell are installed with pipelines. Each time the reverse osmosis membrane is replaced, the pipeline needs to be disassembled and installed. The operation is complicated, it is easy to leak, and there are safety hazards. When replacing the reverse osmosis membrane, open one end cap and the filter element needs to be completely pulled out. There needs to be enough space when the membrane shell is installed horizontally or vertically, which is very inconvenient in a narrow installation position. The reverse osmosis membrane center tube seal original is installed inside the end cap. Once damaged, the pipeline and end cap need to be disassembled and installed, and the sealing ring needs to be replaced. The process is cumbersome and the installation requires skills. Non-professionals cannot operate it, which is time-consuming and laborious. When replacing the filter element, a large amount of water will flow out of the membrane shell, affecting the on-site environment and causing inconvenience to on-site construction. There are usually deposits or crystals in the filter shell, and the filter element is difficult to disassemble and install. In response to the above problems, the inventor proposes a space-saving reverse osmosis membrane shell structure to solve the above problems. Utility Model Content
