Abstract

The invention relates to a backwashing osmosis water purifier capable of timing. According to the invention, the water inlet end of a reverse osmosis (RO) membrane processing unit is provided with a backwashing wastewater pipe; a water outlet pipe of the reverse osmosis (RO) membrane processing unit is connected with a pressure tank; a pipeline connecting the reverse osmosis (RO) membrane processing unit to a water storage bucket is also connected with a one-way valve; the water outlet pipe of the reverse osmosis (RO) membrane processing unit is provided with a timing unit 14; the timing unit 14 and a programmable logic controller (PLC) 15 are in connection; and the programmable logic controller (PLC) 15 controls opening or closing of a water pump according to signals of the timing unit 14. The backwashing osmosis water purifier realizes the following beneficial effects: the service life of a reverse osmosis (RO) membrane is improved; and energy consumption and wastewater output are reduced.

Description

technical field [0001] The invention relates to a water purifier, in particular to a backwash osmotic water purifier. Background technique [0002] At present, the main problem of osmotic water purifier products is that the cost of RO reverse osmosis membrane is high and it is easily damaged. The RO reverse osmosis membrane of the existing reverse osmosis water purifier has a short service life, and the time for replacing the RO reverse osmosis membrane is not well controlled, resulting in either not being replaced in time, or the RO reverse osmosis membrane is replaced before the end of its service life. cause waste. [0003] Therefore, if the RO reverse osmosis membrane can be washed in time to avoid the accumulation of particles on its surface, the service life of the RO reverse osmosis membrane can be increased and the user's use cost can be reduced. Although there are currently related designs for the backwashing of RO reverse osmosis membranes, the existing designs a...
