Description

Technical Field

[0001] The utility model relates to the field of cleaning mechanisms, in particular to a reverse osmosis membrane cleaning mechanism for water treatment equipment. Background Art

[0002] Reverse osmosis membrane is a commonly used water treatment equipment. Its basic structure includes membrane, membrane shell, inlet and outlet parts. Reverse osmosis membrane is an artificial semipermeable membrane with certain characteristics made by simulating biological semipermeable membrane. It 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 reverse osmosis membrane is very small, so it can effectively remove impurities such as suspended matter, organic matter, heavy metals, bacteria and viruses in water. It is an efficient and environmentally friendly water treatment technology with the advantages of low energy consumption, no pollution, simple process and easy operation.

[0003] Reverse osmosis membranes can remove minerals and trace elements from water while retaining those that are beneficial to the human body. However, reverse osmosis membranes are easily contaminated and clogged during use and require regular cleaning. Existing reverse osmosis membrane cleaning mechanisms usually use mechanical brushes or high-pressure water flows to clean the reverse osmosis membranes. However, since it is difficult for brushes or water flows to penetrate into the fine parts of the reverse osmosis membranes, the cleaning is not thorough. In addition, the operation of existing reverse osmosis membrane cleaning mechanisms is relatively cumbersome, which not only increases the difficulty and cost of operation, but also affects the cleaning effect and the operation of the equipment.
