Description
Technical Field
[0001] The utility model relates to the field of RO membrane cleaning, in particular to a RO membrane cleaning device for a reverse osmosis filtering station. Background Art
[0002] RO membrane is a reverse osmosis membrane. Generally, water flows from low concentration to high concentration. Once water is pressurized, it will flow from high concentration to low concentration, which is the so-called reverse osmosis principle: Since the pore size of RO membrane is one millionth of a hair (0.0001 micron), it is generally invisible to the naked eye, and bacteria and viruses are 5000 times larger than it. Therefore, only water molecules and some mineral ions can pass through (the ions passing through have no benefit or loss orientation), and other impurities and heavy metals are discharged from the wastewater pipe. All seawater desalination processes and astronaut wastewater recycling and treatment use this method, so RO membrane is also called the high-tech "artificial kidney" in vitro. At home and abroad, in the fields of medicine, military and civilian, top-level RO membranes are used for polymer filtration.
[0003] After long-term use, the RO membrane used in the existing reverse osmosis filtration station needs to be cleaned to remove the filtered impurities and dust. The existing RO membrane cleaning device for the reverse osmosis filtration station still has some problems during cleaning: the RO membrane is not equipped with a clamping assembly when it is cleaned vertically, resulting in poor stability during RO membrane cleaning, and it is easy to move, so that the water from the nozzle cannot be sprayed to the RO membrane. At the same time, it is inconvenient to clean the RO membrane from the inside, which reduces the cleanliness of the RO membrane cleaning. For this reason, a RO membrane cleaning device for a reverse osmosis filtration station is designed. Utility Model Content
