[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. The equipment used for reverse osmosis is mainly hollow fiber or roll membrane separation equipment, which can intercept various inorganic ions, colloids and macromolecular solutes in the water to obtain purified water. It is often used in seawater, fresh water from brackish water, water softening, wastewater treatment, as well as purification, concentration, and separation in the food, pharmaceutical industry, and chemical industry.

[0003] The reverse osmosis membrane used in reverse osmosis treatment technology is the core component for realizing reverse osmosis. It is generally installed in the reverse osmosis membrane shell. When the reverse osmosis membrane shell is disassembled and maintained later, a disassembly tool is needed. However, the existing reverse osmosis membrane shell disassembly tools are scattered, and it is inconvenient to integrate the tools together, which is not conducive to carrying. For this reason, we propose a portable reverse osmosis membrane shell disassembly tool. Utility Model Content

[0022] The limiting assembly 6 includes a fixing block 61 symmetrically arranged on one side of the nut 2, a groove 62 is provided on one side of the two groups of fixing blocks 61, a spring 63 is provided inside the two groups of grooves 62, one end of the two groups of springs 63 is connected to a guide rod 64 sleeved with the groove 62, one end of the two groups of guide rods 64 is provided with a contact plate 65 that contacts the ejection plate 5, and one side of the contact plate 65 is provided with a limiting rod 66 that limits the displacement of the force rod 4 and the ejection plate 5, and the force rod 4 and the ejection plate 5 are provided with a through hole 67 sleeved with the limiting rod 66 on the side facing the limiting rod 66. When the force rod 4 and the ejection plate 5 are integrated with the nut 2, the contact plate 65 can be pulled in the direction away from the special-shaped groove 3, so that the contact plate 65 drives the guide rod 64 to move outward in the groove 62, so that the spring 63 is deformed by force. Then, the limiting rod 66 on one side of the contact plate 65 can be moved away from the special-shaped groove 3, and then the force rod 4 and the ejector plate 5 are placed in the special-shaped groove 3 in turn, so that the ejector plate 5 is placed on one side of the force rod 4, and the surfaces of the force rod 4 and the ejector plate 5 are in contact with the inner wall of the special-shaped groove 3, and the positions of the force rod 4 and the ejector plate 5 are adjusted so that the through hole 67 in the middle of the force rod 4 and the ejector plate 5 is facing the limiting rod 66, and then the pulling on the contact plate 65 is released, and the return property of the spring 63 is utilized to make the contact plate 65 drive the limiting rod 66 to move into the through hole 67 through the guide rod 64 under the action of the spring 63, so as to limit the force rod 4 and the ejector plate 5, thereby limiting the force rod 4 and the ejector plate 5 to the special-shaped groove 3 on one side of the nut 2, so that the force rod 4 and the ejector plate 5 can be integrated with the nut 2.

[0023] An arc groove 7 is provided on one side of the ejector plate 5. The arc groove 7 has a diameter equal to that of the booster rod 4.
