Abstract

The invention relates to a flow-control backwash osmotic water purification machine with a real-time monitoring function. According to the invention, a pressure tank is connected to the water outlet pipe of an RO reverse osmosis membrane treatment unit; a check valve is connected to a pipeline connecting the outlet pipe of the RO reverse osmosis membrane treatment unit and a water storage tank; sensors are connected with a PLC; the PLC controls the on/off of a water pump according to signals from the water flow sensors; a water flow monitoring device is arranged at the water outlet end of each level of filter core of a filtering unit; the water flow monitoring devices and TDS detection devices are all connected with a display device. With the water purification machine, the service life of the RO reverse osmosis membrane is prolonged, energy consumption is reduced, and wastewater output is 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...
