Description

Technical Field

[0001] The present application relates to the field of water treatment, and in particular to a method for controlling alternating use of a one-in-use and one-in-standby water treatment control system. Background Art

[0002] Water hardness is primarily composed of cations: calcium (Ca²⁺) and magnesium (Mg²⁺) ions. When hard water passes through the ion exchange resin layer of the exchanger, the calcium and magnesium ions in the hard water are exchanged for the sodium ions in the ion exchange resin. The ion exchange resin absorbs the calcium and magnesium ions while releasing the sodium ions, resulting in softened water. Softened water is less likely to form carbonate scale and magnesium hydroxide scale.

[0003] In the related water treatment technology, only one water treatment device is provided. This water treatment device needs to perform both the water production process and the regeneration process. As a result, when the water treatment device is performing the regeneration process, the water production process must be stopped, interrupting the water supply to the water-using area.

[0004] Regarding the above-mentioned related technologies, the inventor believes that if only one water treatment device is set up, the water treatment device must stop running the water production process when performing the regeneration process, thereby failing to form a continuous water supply to the water-using area, which is very inconvenient to use.

The regenerative turbine and the regenerative transmission gear set are gear-driven. The regenerative transmission gear set and the first control disk 7 are gear-driven. During regeneration, the incoming water drives the regenerative turbine to rotate, driving the internal gear of the regenerative transmission gear set to rotate, and the rotating gear drives the first control disk 7 to rotate.

[0069] When the first water treatment device starts to regenerate, the first regeneration metering mechanism 5 drives the first control disk 7 to rotate to the regeneration state. The first control disk 7 passes water to the second external source receiving valve 6', so that the second external source receiving valve 6' opens. The water entering the second external source receiving valve 6' drives the second regeneration metering mechanism 5' to rotate. The second regeneration metering mechanism 5' drives the second control disk 7' to rotate to the water production operation state, and the second water treatment device starts to produce water.

[0071] The structure of the second regenerative metering turbine mechanism is the same as that of the first regenerative metering turbine mechanism, and will not be described in detail here.

[0072] When the second water treatment device starts to regenerate, the second regeneration metering mechanism 5' drives the second control disk 7' to rotate to the regeneration state.

[0074] The first valve shell is provided with a first water inlet channel 20 and a first water outlet channel 30. The first water inlet of the first tank body 1 is connected to the first water inlet 8 through the first water inlet channel 20, and the first water outlet of the first tank body 1 is connected to the first water outlet 9 through the first water outlet channel 30.

[0075] The first water outlet metering mechanism 10 is arranged near the first water outlet 9 of the first valve shell, and is used for metering the water production of the first water treatment device and driving the first control disc 7 to rotate. The first water outlet metering mechanism 10 is a first water outlet metering turbine mechanism.

[0076] The first water outlet metering turbine mechanism comprises a water outlet turbine and a water outlet transmission gear set. The water outlet transmission gear set comprises a plurality of gears. The water outlet turbine is in gear transmission with the water outlet transmission gear set. The water outlet transmission gear set is in gear transmission with the first control disc 7. The water outlet drive of the first water outlet valve 42 drives the water outlet turbine to rotate, drives the gears of the water outlet transmission gear set to rotate, and the rotating gears drive the first control disc 7 to rotate.

The first water outlet valve 42 is arranged near the first water outlet 9 and is connected to the first water outlet 9 and the first water outlet channel 30 respectively, and is used for controlling the outflow of softened water converted from hard water. The first water outlet metering mechanism 10 is located in the passage between the first water outlet valve 42 and the first water outlet 9. The first regeneration control valve 43 is arranged near the first regeneration metering mechanism 5 and is located above and parallel to the first external source receiving valve 6. The first regeneration control valve 43 is connected to the first regeneration metering mechanism 5, the first water inlet 8 and the first injector 3 respectively, and is used for controlling the flow direction of hard water.

The first quick washing discharge valve 45 is located in the first discharge port 2 and is connected to the first water outlet channel 30 and the first discharge port 2, and is used for controlling the discharge of waste liquid at the first water outlet of the first tank body 1. The first discharge valve 46 is located in the first water outlet channel 30 and below the first quick washing discharge valve 45, and is connected to the first water inlet channel 20 and the first discharge port 2, and is used for controlling the discharge of waste liquid at the first water inlet of the first tank body 1.

[0079] Two liquid inlet openings are formed in the valve body of the first water inlet valve 41, and two liquid inlet openings are formed in the valve body of the first water outlet valve 42.

[0080] Two liquid inlets of the first water inlet valve 41, one above the valve disc of the first water inlet valve 41 and the other below the valve disc of the first water inlet valve 41, can control the opening or closing of the first water inlet valve 41 at the same time. The liquid inlet above is pressure relief, and the liquid inlet below is under pressure, so the first water inlet valve 41 can be opened.

[0081] The two liquid inlets can also be located on the same side of the valve disc of the first water inlet valve 41, and simultaneously pressure relief or under pressure, so as to open or close the first water inlet valve 41.

[0082] The two liquid inlets of the first water outlet valve 42 are arranged and work in the same way as the liquid inlets of the first water inlet valve 41, which will not be repeated here.

[0083] A liquid inlet is formed on the valve body of the first regeneration control valve 43, the valve body of the first brine safety valve 44, the valve body of the first quick washing discharge valve 45, and the valve body of the first discharge valve 46.

For example, the liquid inlet of the first regeneration control valve 43 is under pressure, so the first regeneration control valve 43 is opened.

[0085] Each of the aforementioned liquid inlets is in communication with the first control disc 7.

[0086] A plurality of small holes are formed on the first control disc 7, and a first control channel 40 through which water can pass is arranged between each liquid inlet and the first control disc 7, so that the liquid inlet is connected to the small hole through the first control channel 40. When the first control channel 40 connects the liquid inlet to the small hole, the liquid inlet discharges water through the first control channel 40 to form pressure on the valve disc of the first water inlet valve 41.

[0087] When the small hole is connected to the corresponding first control channel 40, it means that the liquid inlet corresponding to this first control channel 40 is under pressure. When the small hole is not connected to the corresponding first control channel 40, it means that the liquid inlet corresponding to this first control channel 40 is pressure relief, so that the opening or closing of the valve corresponding to the liquid inlet is realized by the pressure or pressure relief of the liquid inlet.

[0088] The first control disc 7 is connected with the second foreign matter receiving valve 6 through a first control channel 40, when the small hole in the first control disc 7 is connected with the corresponding first control channel 40 of the second foreign matter receiving valve 6, the hard water in the first control disc 7 enters the first control channel 40, the hard water opens the second foreign matter receiving valve 6, after the second foreign matter receiving valve 6 is opened, the hard water in the second water inlet 8' flows to the second regeneration metering mechanism 5 through the second regeneration channel 60', which can drive the second control disc 7' to rotate.
