Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
The drinking water-saving filtering device shown in fig. 1 comprises a pre-filtering device 3, an RO membrane reverse osmosis filter 6 and a controller, wherein tap water is connected with a water inlet of the pre-filtering device 3, a water outlet of the pre-filtering device 3 is connected with the RO membrane reverse osmosis filter 6 through a water inlet valve 4 and a high-pressure pump 5, a water outlet end of the RO membrane reverse osmosis filter 6 is respectively connected with a pure water pipe 12 and a backwashing pipe 11 through a shunt valve 8, the pure water pipe 12 is connected with a pure water pressure tank 10 through a high-pressure switch, the backwashing pipe 11 is communicated with the high-pressure pump, the RO membrane reverse osmosis filter 6 is connected with a concentrated water pipe, and a proportional valve 7 is arranged on the concentrated water pipe.
Specifically, the pre-filter device 3 is sequentially provided with a first filter PP wool 301, a first filter granular carbon 302 and a first filter compressed carbon 303 from front to back.
Specifically, an ultra-low water level sensor, a medium water level sensor and a high water level sensor are arranged in the pure water pressure tank 10.
Specifically, the high-voltage switch is a two-way switch, and the pure water pressure tank 10 performs reverse action by the high-voltage switch, and the RO membrane reverse osmosis filter 6 is flushed with pure water in the pure water pressure tank 10.
Specifically, the shunt valve is a 2:1 shunt valve.
The working principle is as follows:
the water yield of the concentrated water is controlled by utilizing the opening degree of the proportional valve, so that the water-saving function is achieved;
the pure water is subjected to secondary circulation through the shunt valve, the RO membrane reverse osmosis filter 6 is backwashed by the pure water, the backwashing pressure difference is generated by adjusting the opening degree of the proportional valve, and when backwashing is performed, the opening degree of the proportional valve is instantly adjusted to be larger, so that the pressure difference is instantly increased, the flushing is cleaner, and the quality of the pure water is improved.
The utility model discloses not be limited to the embodiment, anybody should learn the structural change who makes under the teaching of the utility model, all with the utility model discloses have the same or close technical scheme, all fall into the utility model discloses an within the protection scope.
The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
