Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of reverse osmosis membrane disassembly, in particular to a reverse osmosis membrane element disassembly tool. BACKGROUND

[0002] In the field of environmental protection and water treatment, reverse osmosis membranes are widely used because they can separate and purify raw water. In reverse osmosis system equipment, reverse osmosis membranes are core components that are installed in dedicated membrane housings. Common membrane housings are divided into 1-7 cores according to the number of reverse osmosis membranes they contain. Reverse osmosis membrane elements need to be regularly disassembled for cleaning, maintenance, or replacement after long-term use to ensure the filtration efficiency of the system.

[0003] Traditional reverse osmosis membranes have some defects during disassembly, such as:

[0004] 1. The fixing tools used for disassembling reverse osmosis membranes can only fix specific sizes of membrane housings. Special clamps need to be replaced for different diameters and lengths of membrane housings, which is cumbersome to operate.

[0005] 2. The existing disassembly tools need to manually adjust the position of the disassembly tool or the membrane housing so that they are at the same horizontal height as the reverse osmosis membrane. The adjustment process prolongs the disassembly time and is time-consuming and labor-intensive.

[0006] 3. The existing disassembly tools use a single screw for disassembly, such as the Chinese patent CN221561153U: a reverse osmosis membrane element disassembly tool. This scheme uses a single screw to disassemble the reverse osmosis membrane, which is low in efficiency. SUMMARY
