Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes, in particular to a protective device for preventing a reverse osmosis membrane from being damaged by pressure. Background Art

[0002] At present, the reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane, and is the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate these substances and water under the action of higher osmotic pressure than the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in water. The system has the advantages of good water quality, low energy consumption, no pollution, simple process, and easy operation. Because the reverse osmosis membrane element is very fragile during use, it needs good protection, otherwise the reverse osmosis membrane element will be damaged and lose its filtering effect. Therefore, how to protect the reverse osmosis membrane element is very important.

[0003] For example, the patent application with application number CN201820134809.7 includes a tank body, a control panel, a water inlet and a foot. The outer surface of the tank body is provided with a control panel, the bottom of the tank body is fixedly supported by four foots, a faucet is fixedly installed at the bottom of the side of the tank body, a sewage outlet is provided at the upper end of the other side of the tank body, a screw cover is installed on the sewage outlet, a water inlet is provided at the upper end of the tank body, a large cover is fixedly installed at one end of the water inlet, and the large cover is hinged to the tank body through a hinge. The utility model protects the reverse osmosis membrane element by installing a steel mesh, a filter device and a buffer plate inside the tank body, and the three-layer structure ensures that the reverse osmosis membrane element will not be damaged, and better ensures the filtering effect of the reverse osmosis membrane element. By installing an air pump, the pressure inside the tank body can be steadily increased to ensure the gentle filtration of water, and there will be no major impact force to destroy the reverse osmosis membrane element.

[0004] However, when the above-mentioned protective device is used to protect the reverse osmosis membrane, the wire mesh is used to filter large debris, the filter device filters tiny organisms and impurities, and the buffer plate buffers the impact force. However, when the wire mesh is cleaned, the reverse osmosis membrane cannot be used to separate substances and water, thereby reducing the use efficiency of the protective device, and the buffer plate cannot completely block the impact water, thereby reducing the protective effect of the protective device on the reverse osmosis membrane. It is urgent to design a protective device that can prevent the reverse osmosis membrane from being compressed and damaged to solve the above problems. Utility Model Content
