Abstract

The invention relates to a backwash osmotic water purification machine with a monitoring function. According to the invention, a pressure tank and a check valve are connected to the water outlet pipe of an RO reverse osmosis membrane treatment unit; a water flow monitoring device and a TDS detection device are arranged at the water outlet end of each level of filter core of a filtering unit; a wastewater pipe is provided with a wastewater proportioner; the water flow monitoring devices and the TDS detection devices are connected with a PLC, and are connected to a display device through the PLC; the PLC transmits processed signals to the display device; a water pump is connected to the PLC; the PLC controls the on / off of the water pump. 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 with monitoring. 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 relatively cheap filter unit can be monitored in time at the water inlet, when a filter element of the filter unit fails or needs to be replaced, the filter element should be replaced in time to ensure that the water quality entering the RO reverse osmosis membrane is relatively good. It can guarantee the service lif...
