た。 In a water softening device that alternately softens hard water and regenerates ion exchange resin, determine the interval from the previous regeneration to the current regeneration, estimate the amount of passage (hardness portion) during that time, and The amount of salt water is regulated by the salt water valve in the salt water tank (defining the regeneration start level A and regeneration end level B in one cycle of regeneration), and during regeneration, the control valve works to suck a specified amount of salt water and regenerate the ion exchange resin. The method of doing this was taken.
However, because conventional methods do not have a means for detecting the concentration of salt water during regeneration and a means for confirming the use of salt water, salt bridges may form, or the necessary concentration may not be generated due to forgetting to replenish salt, etc. There have been cases where the ion exchange resin cannot be regenerated due to insufficient supply of salt water due to line clogging, etc.

る。 In view of the above points, the present invention aims to confirm the concentration of salt water and the fact of the use of salt water when regenerating an ion exchange resin, and to reliably regenerate the ion exchange resin. A resin cylinder filled with the ion exchange resin, a salt water tank storing salt water for regenerating the ion exchange resin, and a resin cylinder fastened to the resin cylinder,
In a hard water softening device consisting of a control valve 5 that alternately softens hard water and regenerates the ion exchange resin, and a salt water line that connects the salt water tank and the control valve, it corresponds to the amount of salt water used when regenerating the ion exchange resin. A sensor is installed in the salt water area (between level A and level B) in the salt water tank to receive an electrical signal from the sensor during ion exchange resin regeneration, and the amount of the electrical signal is set to a set value (salt water concentration confirmation signal amount). If it is below, a salt water concentration shortage alarm will be issued, if it is above the set value, a salt water supply signal will be issued, and then the set value (salt water supply confirmation signal amount)
The salt water detection device is comprised of a controller configured to stop the salt water supply signal when:

is an ion exchange resin, which is filled in the resin cylinder 2. A control valve 5 is installed at one end of the resin cylinder 2.
The control valve is configured such that hard water flows in from one end of the control valve, becomes soft water from the other end, and is transferred to the outside of the system. 4 in the figure is a salt water tank that stores salt water 3 used for regenerating the ion exchange resin. The salt water tank 4 is provided with a salt water valve 11 for regulating the amount of salt water 3.
The salt water valve 11 is connected to the control valve 5 through a salt water line 6.
By this function, the salt water level A7 at the start of regeneration is set. Raw salt 13 is stored in the salt water tank via a net 12, and after being regenerated, it is dissolved in water supplied through the salt water line to produce salt water of a specified concentration. A sensor 9 is installed between the salt water level AB in the salt water tank to detect the electrical conductivity of the salt water.
is provided and connected to the control device 10 via a signal line. This control device 10 receives an electric conductivity signal from a sensor 9 during ion exchange resin regeneration, and if the signal amount is less than a set value (necessary salt water concentration confirmation signal amount), a salt water concentration alarm 14 is installed.
If it exceeds the set value, the salt water supply indicator 15 will display the salt water supply, and the set value (salt water supply to confirm the state where salt water has disappeared) will be displayed. The system is configured to stop displaying the salt water supply if the quantity of the supply confirmation signal is below (supply confirmation signal amount). Note that the control valve 5 is provided with a drainage line 16 for discharging wastewater during ion exchange resin regeneration.

確実となる。 Next, the effect will be explained. During water softening, raw water (hard water) flows in from one end of the control valve, is softened by the action of the ion exchange resin, becomes soft water, and is transferred to the outside of the system from the other end of the control valve. When regenerating the ion exchange resin, the control valve works to suck the salt water between levels A and B in the salt water tank through the salt water line to regenerate the ion exchange resin, and its waste water is discharged from the system through the drainage line. When salt water is used up to level B, water is supplied to level A through the salt water line by the action of the control valve. The supplied water dissolves the raw salt and reaches a predetermined concentration by the time of the next regeneration. When the ion exchange resin starts to be regenerated, the control device detects the electrical conductivity signal from the sensor, and if the signal amount is above the set value (required salt water concentration confirmation signal amount), the salt water supply indicator will be displayed. hand,
Displays the salt water supply, and stops displaying the salt water supply when the salt water level becomes below the sensor due to the use of salt water and the signal amount becomes below the set value (salt water supply confirmation signal amount). However, if salt water is not used due to clogging of the salt water line or salt water valve, etc., the display indicating that salt water is being supplied will be displayed even after the regeneration time set by the control valve has elapsed. In addition, if a salt bridge forms in the raw salt layer and the salt water concentration necessary for regeneration cannot be obtained, and the signal amount from the sensor is below the set value at the start of regeneration, the salt water concentration alarm will indicate insufficient salt water concentration. . Note that by locating the sensor slightly above level B, confirmation of the amount of salt water used becomes reliable.
