Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment tools, in particular to a reverse osmosis membrane disassembly tool. Background Art
[0002] The reverse osmosis membrane is a core component in a water treatment device, used to remove dissolved salts and other pollutants in water. After long-term use, the reverse osmosis membrane may be worn and aged, resulting in a decline in the performance of the membrane, affecting the water purification effect and the quality of the effluent water. Disassembling and replacing the membrane can ensure that the device can maintain high water quality and high efficiency operation. However, it should be noted that disassembling and replacing the reverse osmosis membrane is a complex process and requires operation by specialized technical personnel. In the reverse osmosis system, a salt seal ring with a sealing function is installed at the end to prevent the reverse osmosis inlet water from directly entering the concentrated water end, but the salt seal ring also brings difficulties to the membrane disassembly. The common method is to disassemble the end caps at both ends and manually push from one end and exit from the other end. However, the rubber material salt seal ring increases the frictional resistance and increases the difficulty of the membrane disassembly work. Summary of the Utility Model

[0005] Further, in the utility model, both the force receiving disk and the buffer gasket are circular in shape; the force receiving disk and the buffer gasket are connected together to the end face of the pull rod through fastening screws.
[0006] Further, in the utility model, the buffer gasket is a rubber gasket, and the outer peripheral edge of the rubber gasket adopts a soft rubber ring structure.
[0007] Further, in the utility model, the pull rod is composed of several unit rods, and adjacent two unit rods are internally connected in series through a screw rod.
[0008] Further, in the utility model, the pull ring is connected to the end of the pull rod through a screw rod or a bolt.

[0019] The present utility model is a reverse osmosis membrane disassembly tool, which has a pull rod. One end of the pull rod is provided with a pull ring 9, and the other end of the pull rod is equipped with a force-receiving disc 13. A buffer gasket 12 is attached to the inner side surface of the force-receiving disc. The diameter of the buffer gasket is greater than or equal to the diameter of the force-receiving disc; further, in the present utility model, the force-receiving disc is a steel circular disc. Further, in the present utility model, both the force-receiving disc and the buffer gasket are circular in shape; the force-receiving disc and the buffer gasket are connected to the end face of the pull rod together through fastening screws 14. Further, in the present utility model, the buffer gasket is a rubber gasket, and the outer edge of the rubber gasket adopts a soft rubber ring structure, further reducing the friction with the inner wall of the housing in the reverse osmosis membrane system during use.
[0020] See Figure 1 As shown in the figure, it is the entire reverse osmosis membrane system. Inside the housing, several reverse osmosis membranes are installed. Adjacent reverse osmosis membranes are connected into a whole through connecting pipes. The reverse osmosis membranes and the inner wall of the housing are separated and installed through plastic gaskets, and end caps are installed at both ends.
[0021] When the tool of the present utility model is actually used, see the attached Figure 3 figure, and its operating principle is as follows:
[0022] After first disassembling the end caps at both ends, connect the unit rods in the demoulding tool one by one. The connection length should be determined according to the total length of the reverse osmosis membrane system in the actual scenario. Pass the spliced pull rod through the hollow in the middle of the membrane connection pipe, connect one end to the pull ring, and the other end to the force-bearing disc and the buffer gasket. Pull the entire reverse osmosis membrane outwards from the direction of the pull ring. There is a buffer gasket made of rubber between the force-bearing disc and the membrane end face as a buffer to ensure that the membrane element is not scratched. At the same time, a structure with a softer soft rubber ring is arranged on the outer circle of the buffer gasket to also protect the inner wall of the membrane shell during pulling.
[0023] In the present utility model, the pull rod, the pull rings at both ends of the pull rod, the force-bearing disc and the buffer gasket are all designed with detachable structures, which are convenient for transportation, storage and replacement after damage, and can be flexibly assembled and installed according to the actual situation on site, which is very convenient.

In addition, the tool also has the characteristics of being convenient to carry, easy to store, time-saving and labor-saving, protecting the membrane shell, protecting the membrane body, and improving efficiency, and is a very useful simple membrane-disassembling tool.
