Description

Technical Field

[0001] The utility model relates to the technical field of pure water treatment equipment, in particular to pure water treatment equipment. Background Art

[0002] Pure water refers to water without impurities. The chemical purity of pure water is extremely high. When preparing pure water, the raw water needs to be filtered first. When filtering the raw water, a reverse osmosis membrane is used for filtration. When the reverse osmosis membrane filters the raw water, some impurities will adhere to the outer wall of the reverse osmosis membrane. Excess impurities remaining on the reverse osmosis membrane will clog the filter pores and affect the filtered water flow.

[0003] The existing announcement number is CN217746530U, and its name is a pure water membrane washing device for an RO pure water machine, including a pure water machine, a water inlet pipe and a pure water pipe, a cleaning shovel block and a crushing blade. After the pure water enters the pure water machine, the rotating fan blades will drive the cleaning shovel block to rotate through the first rotating ring, and the cleaning shovel block will scrape off the scale on the reverse osmosis membrane. At the same time, the water wheel will rotate through the crushing blade, and the crushing blade will crush the scale and pass it through the reverse osmosis membrane to be discharged through the waste water pipe. This solves the problem that the scale cannot be removed when the traditional pure water is used to clean the reverse osmosis membrane.

[0004] However, when using a crushing blade to remove the solidified scale on the reverse osmosis membrane, the rotating blade will scratch the reverse osmosis membrane while breaking the scale, causing the reverse osmosis membrane to have a poor effect in filtering pure water, thereby affecting the filtering effect of pure water.
