As shown in fig. 1, an embodiment of the present invention provides a water hardness controller, including: a water hardness control means 10 for performing softening treatment of raw water and delivering soft water obtained after the treatment to a water hardness detection means 20; the water hardness detecting means 20 detects a hardness value of the soft water to determine whether the soft water satisfies a hardness standard.

In this embodiment, the raw water is water that needs to be softened, and is, for example, water having a high hardness in a boiler or a heating facility. After the raw water is input to the water hardness controller, the raw water may be softened by the water hardness controller 10, and the soft water obtained after the softening may be transferred to the water hardness detecting device 20. The water hardness detecting means 20 performs hardness value detection on the soft water so that whether the hardness standard is satisfied can be determined according to the hardness value of the soft water. If the hardness criterion is not met, the soft water may be further softened until the hardness criterion is met. Wherein, in practical application, the corresponding hardness standard can be preset according to the water quality requirement.

In the present embodiment, the water hardness control device 10 is not limited to the mode of softening the raw water, and may be, for example, a liquid or solid softening agent added to the raw water to soften the raw water, or may be softened by an adsorption device having an ion adsorption function.

Alternatively, for convenience of handling and cost saving, as shown in fig. 2 and 9, the water hardness control apparatus 10 may include a control valve 110, a resin tank 150, and a salt tank 130, wherein the resin tank 150 is used for adsorbing ions in raw water using stored resin to soften the raw water; a salt tank 130 for storing brine for replacing the ions adsorbed in the resin; and a control valve 110 for controlling whether the brine stored in the salt tank 130 is transferred to the resin tank 150.

Since the adsorption capacity of the resin is limited, when the adsorbed ions reach a certain level, the adsorption performance thereof is significantly reduced or the ions cannot be adsorbed any more, so that the brine stored in the salt tank 130 can be introduced into the resin tank 150 through the control valve 110 to replace the ions adsorbed in the resin, and the liquid can be separately discharged after the replacement is completed. After the ion absorbed in the resin is replaced, the adsorption function of the resin is activated again, and the ion can be used for absorbing the ion in the raw water again to realize softening treatment. The ions that can be adsorbed by the resin include, but are not limited to, calcium and magnesium ions.

The salt tank 130 may directly store the liquid salt water; or the solid salt blocks and water may be stored, and when the salt water is required to be transferred to the resin tank 150, the salt blocks and the water are mixed to form the salt water.

Alternatively, the control valve 110 may control whether the saline stored in the salt tank 130 is transferred to the resin tank 150 according to a set time period or a raw water treatment volume, that is, may control the activation process of the resin according to a set time period or a raw water treatment volume.

For example, when the set time period is 30 days, the control valve 110 transfers the brine stored in the salt tank 130 to the resin tank 150 once every 30 days to replace the ions adsorbed in the resin.

For another example, the water hardness control device 10 may include a raw water treatment volume detecting element, and the control valve 110 may transfer the salt water stored in the salt tank 130 to the resin tank 150 once per 100 liters of raw water softened by the water hardness control device 10 when the set raw water treatment volume is 100 liters, so as to replace the ions adsorbed in the resin. Wherein, the raw water treatment volume detection element can be a flowmeter.

Alternatively, in order to be able to more timely and intelligently control the activation time of the resin adsorption function to ensure the softening effect, the control valve 110 may control whether the brine stored in the salt tank 130 is delivered to the resin tank 150 according to the hardness value of the soft water detected by the water hardness detecting means 20. That is, when the water hardness detecting means 20 detects that the hardness value of the soft water does not satisfy the hardness standard, indicating that it is likely that the adsorption capacity of the resin in the resin tank 150 is insufficient, the ion adsorbed in the resin needs to be replaced with the brine, and thus the brine stored in the salt tank 130 can be transferred to the resin tank 150.

Optionally, for convenience of operation, the control valve 110 may control whether the brine stored in the salt tank 130 is delivered to the resin tank 150 according to an instruction sent by the cloud server. The cloud server may determine whether an instruction needs to be sent according to the received soft water hardness value detected by the water hardness detection device 20, so as to control the salt water stored in the salt tank 130 to be delivered to the resin tank 150; alternatively, the cloud server may send the resin activation condition to a water hardness controller, for example, a set time period or raw water treatment volume, so that the control valve 110 may control whether the brine stored in the salt tank 130 is delivered to the resin tank 150 according to the set time period or raw water treatment volume.

Optionally, the control valve 110 may further control whether soft water is delivered to the water hardness detecting means in order to flexibly control the detection period of the water hardness.

Alternatively, the control valve 110 may further control the discharge of the raw water or soft water input into the resin tank 150 in order to secure the effect of the softening treatment of the raw water. For example, may be discharged into a sewer through a drain.

Optionally, in order to realize automatic control and improve the intelligence degree of the water hardness controller, the water hardness control apparatus 10 may further include at least one of a salinity detection sensor, a first level sensor, and a raw water pressure sensor, wherein the salinity detection sensor 140 is configured to detect a salinity value of the brine in the salt tank 130 to determine whether the salinity value is lower than a preset salinity threshold; a first liquid level sensor 135 for detecting a water level inside the salt tank 130 to determine whether the amount of salt water in the salt tank 130 is lower than a preset water amount threshold; the raw water pressure sensor 120 is configured to detect a raw water pressure entering the water hardness control device 10 to determine whether the raw water pressure is lower than a preset pressure threshold.

Wherein, when the salinity value of the brine in the salt tank 130 is lower than the preset salinity threshold value, it indicates that the concentration of the brine is insufficient, and the concentration needs to be increased. For example, salt adding treatment can be carried out subsequently, or an alarm prompt for reminding of salt shortage can be sent out.

When the amount of brine in the salt tank 130 is below the preset threshold amount of water, indicating that the amount of brine stored in the salt tank is insufficient, the amount of brine stored needs to be increased.

When the raw water pressure is lower than the preset pressure threshold value, the pressure of the raw water is insufficient, and the water inlet condition of the raw water needs to be adjusted. In practical application, a user can also use the water hardness controller only for pressure detection according to requirements, and low-pressure alarm can be performed when the pressure is insufficient.

For example, in order to detect the pressure of the boiler water, the water outlet of the boiler may be connected to the raw water inlet 112 so that the boiler water is introduced into the detection container for water pressure detection using the raw water pressure sensor 120.

Alternatively, the control valve 110 may include a raw water inlet 112, a salt suction port 115, a soft water outlet, and a waste water discharge port. Wherein, raw water can enter the water hardness control device 10 through the raw water port 112; the brine in the salt tank 130 may be transported to the resin tank 150 through the salt absorption port 115; the raw water or soft water in the water hardness control apparatus 10 may also be discharged through the drain port 116.

Alternatively, the operation state of the control valve 110 may be determined according to the soft water hardness value detected by the water hardness detecting means 20. For example, the control valve 110 may include an operation state, a backwash state, a salt absorption state, a water replenishment state, and a forward washing state, wherein in the salt absorption state, the brine in the salt tank 130 is delivered to the resin tank 150; in the water replenishing state, the raw water can be delivered to the water hardness control device 10.

Optionally, the water hardness control apparatus 10 may further include a gear and a motor assembled with the control valve 110 in order to accurately control the control valve 110. Wherein, through the program control motor, the motor drives the gear to rotate to different positions, so that the control valve 110 is switched to different states, namely, the raw water port 112, the salt absorption port 115, the soft water output port and the wastewater discharge port are controlled to be in an open or closed state.

In this embodiment, the structural schematic of the water hardness detecting device 20 can be seen in fig. 9, and specifically includes: a soft water inlet module 220 connected to the water hardness control device 10 and the sensing container 210, for inputting a first volume of soft water into the sensing container 210; a reagent input module 230 connected to the detection container 210 for inputting a second volume of reagent into the detection container 210; a sensing container 210 for containing a mixed liquid formed of a first volume of soft water and a second volume of reagent; and the water hardness detection module 250 is used for determining the hardness value of the soft water according to the color information of the mixed liquid.

The bottom surface of the detection container 210 is provided with a drainage hole 210i having a certain inclination, and the waste water is drained by the suction pump 262. The overflow hole 210f can prevent the water level sensor 215 from failing to control the water storage height, which causes the problem that the circuit board is damaged due to the overflow of water from the detection container 210. Among them, the overflow hole 210f is preferably provided right opposite to the circuit board.

Optionally, in order to save cost, the detection container 210 may be made of a transparent PC material with high light transmittance, the outer surface of the detection container is sprayed with a matte black paint, and the part needing light transmittance is left out separately by spraying with a mask process.

Optionally, the bottom of the detection container 210 is further provided with a mounting seat or a base, and the mounting seat is provided with a plurality of bolt holes for mounting and fixing.

Optionally, the water hardness controller may also include a main controller, wherein the main controller may control whether to turn off the water inlet solenoid valve 224 according to the liquid level arrival signal. That is, when the water level inside the sensing container 210 reaches a designated first volume, a liquid level reaching signal is fed back to the main controller, or the liquid level reaching signal is directly fed back to the water inlet solenoid valve 224.

For example, as shown in FIG. 4, the main controller of the water hardness controller may be located on a motherboard PCBA40, which motherboard PCBA40 may implement control of all on-line sensing functions.

Wherein the filter screen can be installed on the pipeline of the inlet soft water, and the installation positions of the filter screen, the pressure reducing valve 222 and the one-way check valve 226 are not limited to the positions or the order shown in the embodiment
