Description

Technical Field

[0001] The utility model belongs to the technical field of reverse osmosis membranes, and in particular relates to a reverse osmosis membrane shell head disassembly device. Background Art

[0002] Reverse osmosis membranes are artificial semipermeable membranes with specific properties, modeled after biological semipermeable membranes. They are the core component of reverse osmosis technology. The principle of reverse osmosis technology is to separate substances from water under the influence of a pressure higher than the osmotic pressure of the solution, based on the inability of other substances to pass through the semipermeable membrane. The reverse osmosis membrane's very small pore size allows it to effectively remove dissolved salts, colloids, microorganisms, and organic matter from water. The system offers advantages such as high water quality, low energy consumption, zero pollution, simple process, and easy operation. It has been widely used for the purification and concentration of various liquids.

[0003] When replacing or cleaning the reverse osmosis membrane offline, the end caps at both ends of the reverse osmosis membrane shell need to be removed before the reverse osmosis membrane can be taken out. Since the end caps at both ends are in close contact with the reverse osmosis membrane shell, and after the reverse osmosis membrane shell is installed and used, the end caps are often difficult to remove. Therefore, the main object of the reverse osmosis membrane disassembly device is the head at both ends of the reverse osmosis membrane shell. The head is provided with screw holes. The existing method is to use a stainless steel belt to drive two threaded rods into the screw holes in the head and then directly pull out the head. Because the stainless steel belt will deform, it will gradually get closer when pulled, which will clamp the operator's hand at the operating position, making it difficult to pull out, affecting work efficiency. For this reason, we designed a reverse osmosis membrane shell head disassembly device. Utility Model Content
