[0028] As mentioned in the above background technology, the soft water treatment technology is a process of removing calcium and magnesium ions in water by using ion exchange technology to reduce the hardness of water and achieve the purpose of removing scale. Usually, a soft water treatment device is used for soft water treatment. Although soft water treatment and wastewater recycling are achieved through the existing technology, when the ion concentration in the soft water discharged by the soft water treatment does not meet the standard, the quality of the soft water will be reduced to affect the reuse of the soft water. Therefore, how to ensure that the ion concentration of the soft water discharged by the soft water treatment device meets the standard is a problem that those skilled in the art need to consider. To this end, the inventor of the present application provides a soft water treatment device in one or more embodiments, and the ion concentration of the soft water in the outlet pipe can be detected in real time by an ion concentration detector. When the ion concentration in the soft water exceeds the standard value, the first outlet valve is closed to prevent the waste water that does not meet the standard from being discharged from the outlet, and the return valve is opened to allow the soft water with the ion concentration in the outlet pipe that does not meet the standard to flow back to the filter through the return pipe for re-softening treatment, thereby ensuring that the ion concentration in the soft water discharged from the outlet meets the standard requirements. Thus, one or more problems in the prior art are solved.

[0029] In view of the above-mentioned technical problems, the utility model provides a soft water treatment device, such as Figure 1 As shown, it comprises: a filter 1, the filter 1 comprises a water inlet 2 for discharging hard water into the filter 1 for softening treatment and a water outlet 3 for discharging soft water formed by softening the hard water in the filter 1, the water outlet 3 being arranged at the end of a water outlet pipe 4 extending from the filter 1; a first water outlet valve 5, the first water outlet valve 5 being arranged at a position on the water outlet pipe 4 close to the water outlet 3, for controlling the opening or closing of the water outlet 3; an ion concentration detector 6, the ion concentration detector 6 being arranged on the water outlet pipe 4 for monitoring the ion concentration of the soft water discharged from the filter 1 into the water outlet pipe 4; the water outlet pipe 4 between the water outlet 3 and the ion concentration detector 6 A return water port 7 is provided on the top; a return water pipe 8, one end of which is connected to the return water port 7, and the other end is connected to the filter 1, so as to discharge the soft water with substandard ion concentration into the filter 1 for re-softening treatment; a return water valve 10, which is arranged on the return water pipe 8 near the return water port 7 to control the opening or closing of the return water port 7; wherein the first outlet valve 5 controls the opening or closing of the outlet 3 according to the ion concentration of the soft water in the outlet pipe 4 monitored by the ion concentration detector 6, and the return water valve 10 controls the closing or opening of the return water port 7 according to the ion concentration of the soft water in the outlet pipe 4 monitored by the ion concentration detector 6.

[0030] Specifically, during the normal operation of the soft water treatment device, hard water is discharged from the water inlet 2 into the filter 1 for softening treatment, and the soft water formed by the softening treatment is discharged from the filter 1 into the outlet pipe 4. The ion concentration detector 6 monitors the ion concentration of the soft water discharged from the filter 1 into the outlet pipe 4 in real time. When the ion concentration is within the standard range, the first outlet valve 5 is in an open state, the return valve 10 is in a closed state, and the soft water with the ion concentration meeting the standard is discharged from the outlet 3. When the ion concentration detector 6 detects that the ion concentration of the soft water in the outlet pipe 4 does not meet the standard, the ion concentration detector 6 sends an ion concentration non-standard signal to the controller (not shown in the figure) connected to it for communication, and the controller sends an instruction to close the first outlet valve 5 and open the return valve 10, and the non-standard soft water flows back from the return pipe 8 to the filter 1 for softening treatment again. When the ion concentration detector 6 detects that the ion concentration of the soft water in the outlet pipe 4 meets the standard, the controller sends an instruction to open the first outlet valve 5 and close the return valve 10, and the soft water with the ion concentration meeting the standard is discharged from the outlet 3.

[0031] Compared with the prior art, the soft water treatment device of the present application can detect the ion concentration of the soft water in the water outlet pipe 4 in real time through the ion concentration detector 6. When the ion concentration in the soft water exceeds the standard value, the first water outlet valve 5 is closed to prevent the waste water that does not meet the standard from being discharged from the water outlet 3. At the same time, the return valve 10 is opened to allow the soft water with the ion concentration that does not meet the standard in the water outlet pipe 4 to flow back to the filter 1 through the return pipe 8 for re-softening treatment, thereby ensuring that the ion concentration in the soft water discharged from the water outlet 3 meets the standard requirements.

[0032] In some embodiments, Figure 1 As shown, the ion concentration monitor 6 includes a conductivity probe 11. The conductivity probe 11 is arranged in the outlet pipe 4 and can be immersed in the soft water in the outlet pipe 4. The conductivity probe 11 includes two electrodes. The current on the electrodes is related to the ion concentration in the soft water in the outlet pipe 4. The higher the ion concentration, the greater the current. The ion concentration monitor can convert the current into an ion concentration value and send it to the controller, thereby realizing the control of opening or closing the first outlet valve 5 and the return valve 10.

[0033] In some embodiments, the filter 1 includes a resin filter. The resin filter achieves hard water softening. The resin filter 1 is prior art and will not be described in detail herein.

[0034] In some embodiments, Figure 1As shown, the soft water treatment device also includes a water inlet pipe connected to the water inlet 2, and a water inlet valve 12 for controlling the opening and closing of the water inlet 2 is provided on the water inlet pipe near the water inlet 2. The opening and closing of the water inlet 2 can be controlled by the water inlet valve 12. When the soft water treatment device works normally, the water inlet valve 12 is opened so that hard water can be normally discharged into the filter 1 for softening treatment; when the soft water treatment device fails and needs to be repaired, the water inlet valve 12 is closed to prevent hard water from being discharged into the filter 1 and affecting the repair work. In addition, the flow rate of hard water discharged into the filter 1 can also be controlled by the water inlet valve 12.

[0035] In some embodiments, the soft water treatment device further includes a cleaning mechanism for cleaning the filter 1, such as Figure 1 As shown, the cleaning mechanism includes a cleaning water inlet 13, a drain outlet 14 and a drain valve 15. The cleaning water inlet 13 and the drain outlet 14 are both provided on the filter 1. The drain valve 15 is provided on the drain pipe connected to the drain outlet 14 and is close to the drain outlet 14 to control the switch of the drain outlet 14. After the filter 1 has been running for a period of time, a certain amount of impurities will be deposited on its filter element, thereby affecting the softening treatment effect of the filter 1. For this reason, the filter 1 needs to be cleaned regularly. When the filter 1 is cleaned, the soft water treatment device is in a shutdown state, the water inlet valve 12, the first water outlet valve 5 and the return valve 10 are all in a closed state, and the cleaning water inlet 13 discharges clean water with a certain pressure into the filter 1 to clean the filter element and the inside of the filter 1. At the same time, the drain valve 15 is opened, and the cleaned waste water is discharged from the drain outlet 14. After cleaning, the drain valve 15 closes the drain outlet 14.

[0036] In some embodiments, the cleaning mechanism further includes a clean water tank (not shown), which is connected to the cleaning water inlet 13 to discharge clean water into the filter 1 to clean the filter 1. The clean water tank is provided to ensure that the filter 1 is provided with cleaning water.

[0037] In some embodiments, Figure 1 As shown, the soft water treatment device further includes a water pool 16, which is connected to the water outlet 3. The soft water is discharged into the water pool 16 through the water outlet 3 for precipitation, thereby further improving the water quality of the soft water.

[0038] In some embodiments, Figure 1 As shown, the water pool 16 is further connected to the cleaning water inlet 13. By connecting the water pool 16 to the cleaning water inlet 13, the filter 1 is cleaned with soft water after settling in the water pool 16. The problem of water source for cleaning is solved.

[0039] In some embodiments, Figure 1As shown, the pool 16 is further connected to the cleaning water inlet 13 through a pipeline. A control valve 17 is provided on the pipeline near the cleaning water inlet 13 to control the switch of the cleaning water inlet 13. When the soft water treatment device is in normal operation, the cleaning water inlet 13 can be closed by the control valve 17 to prevent the soft water in the pool 16 from entering the filter 1 and causing waste. At the same time, when cleaning the filter 1, the water volume and water pressure of the clean water can be controlled by the control valve 17 to ensure the cleaning effect of the filter 1.

[0040] In some embodiments, Figure 1 As shown, the soft water treatment device further includes a second water outlet valve 18, which is arranged on the water outlet pipe 4 near the filter 1. When the filter 1 is cleaned, the second water outlet valve 18 is closed to prevent the waste water after cleaning from being discharged into the water outlet pipe 4 and contaminating the water outlet pipe 4.

[0041] In summary, compared with the prior art, the present invention provides a soft water treatment device, which can detect the ion concentration of soft water in the water outlet pipe 4 in real time through the ion concentration detector 6. When the ion concentration in the soft water exceeds the standard value, the first water outlet valve 5 is closed to prevent the waste water that does not meet the standard from being discharged from the water outlet 3. At the same time, the return valve 10 is opened to allow the soft water with substandard ion concentration in the water outlet pipe 4 to flow back to the filter 1 through the return pipe 8 for re-softening treatment, thereby ensuring that the ion concentration in the soft water discharged from the water outlet 3 meets the standard requirements; the filter 1 is cleaned by the cleaning mechanism to ensure the quality of the soft water; and the filter 1 is connected to the cleaning water outlet 13 through the water pool 16, so that the filter 1 is cleaned by the soft water precipitated in the water pool 16.
