After the resin is invalid, the resin needs to be regenerated and recovered, solid salt in a salt tank is dissolved into saturated salt water, and the saturated salt water is injected into a resin tank to exchange adsorbed calcium and magnesium ions so as to regenerate the resin.
The softened filter media storage container 200 serves to store the softened filter media 100 and provide a place for the regeneration fluid to exchange reaction with the softened filter media 100. The size, shape, etc. of the softened filter material storage container 200 may be set as desired.

The regeneration liquid mixing module 300 is used to mix external intake water (raw water) with the regeneration liquid to adjust the regeneration liquid concentration. The regeneration liquid mixing component 300 is specifically provided with a solvent input end, a solution input end and an output end, wherein the solvent input end is connected with an external water inlet pipe and is connected with external water inlet; the solution input end sucks in regeneration liquid; the output end outputs the mixed regeneration liquid, and the mixed regeneration liquid can be directly connected with the softened filter material storage container 200 through a pipeline so as to directly inject the mixed regeneration liquid into the softened filter material storage container 200 to exchange and regenerate with the softened filter material 100 in the softened filter material storage container 200.
The pressure stabilizing module 400 is configured to adjust the water pressure of the external water to a preset standard water pressure, and then input the raw water to the input end of the regenerated liquid mixing module 300 to maintain the water pressure at the input end of the regenerated liquid mixing module 300 at the preset standard water pressure. The preset standard water pressure is a preset water pressure, which can be set according to the model, style, application scenario, etc. of the water softening apparatus softening system. In practical application, the water softening equipment softening system can obtain standard water pressure under corresponding models and scenes through working condition testing, and the standard water pressure is recorded on a main control chip and a nameplate of the water softening equipment softening system as working condition parameters of the water softening equipment softening system.

Whole system carries out steady voltage adjustment to outside water pressure of intaking, makes outside water pressure of intaking maintain at preset standard water pressure, avoids outside water pressure to change and leads to pouring into the water pressure fluctuation of regeneration liquid in softening filter material storage container 200, ensures that softening filter material 100 exchanges regeneration with regeneration liquid under suitable, stable water pressure environment, improves the utilization ratio of regeneration liquid.
As shown in fig. 2, in one embodiment, the pressure stabilizing assembly 400 includes a water pressure sensor 410 and a pressure stabilizing unit 420, which are connected to each other, wherein the water pressure sensor 410 collects the water pressure of the external inlet water, and the pressure stabilizing unit 420 adjusts the water pressure of the external inlet water to a preset standard water pressure when the water pressure of the external inlet water is different from the preset standard water pressure.
The water pressure sensor 410 is disposed on the water inlet pipe, and is used for detecting the water pressure in the water inlet pipe, that is, collecting the water pressure of the external inlet water. The water pressure sensor 410 collects external water inflow water pressure data and then sends the external water inflow water pressure data to the pressure stabilizing unit 420, and the pressure stabilizing unit 420 judges whether the external water inflow water pressure is the same as a preset standard water pressure; if the pressure regulating unit 420 regulates the pressure of the external water to a predetermined standard pressure.
As shown in fig. 3, in one embodiment, the pressure stabilizing unit 420 includes a pressure stabilizing pump 422 and a pressure stabilizing pump controller 424, and the pressure stabilizing pump controller 424 obtains a water pressure difference value between the external water inlet pressure and a preset standard water pressure, and controls the pressure stabilizing pump 422 to operate according to the water pressure difference value, so as to adjust the external water inlet pressure to the preset standard water pressure.
In this embodiment, the pressure stabilizing unit 420 uses the pressure stabilizing pump 422 as a water pressure adjusting device, and when the pressure stabilizing pump controller 424 compares the external water inlet pressure with the preset standard water pressure, the pressure stabilizing pump 422 is controlled to start, and the water pressure is adjusted according to the difference between the external water inlet pressure and the preset standard water pressure, so that the final external water inlet pressure is the same as the preset standard water pressure. It can be understood that when the external water inlet pressure is greater than the preset standard water pressure, the pressure stabilizing pump 422 works to gradually reduce the water pressure in the pipeline to the preset standard water pressure; when the external water inlet pressure is lower than the preset specific standard water pressure, the pressure stabilizing pump 422 works to gradually increase the water pressure in the pipeline to the preset standard water pressure. The stabilivolt pump controller 424 can adopt an adaptive control mode to control the stabilivolt pump 422 to work, when the difference value is large, the water pressure is changed at a large speed, and when the difference value is relatively small, the water pressure is changed at a small speed, and the water pressure adjusting speed and the adjusting stability are considered.

In this embodiment, the pressure stabilizing unit 420 employs the pressure tank 426 as a water pressure adjusting device, and when the pressure tank controller 428 compares that the external water pressure is different from the preset standard water pressure, the water inlet valve/drain valve on the pressure tank 426 is controlled to open, and the water pressure is adjusted according to the water pressure difference between the external water pressure and the preset standard water pressure, so that the final external water pressure is the same as the preset standard water pressure. It can be understood that when the external water pressure is greater than the preset standard water pressure, the pressure tank 426 operates to gradually reduce the water pressure in the pipeline to the preset standard water pressure, and specifically, the pressure tank controller 428 controls the water inlet valve of the pressure tank 426 and adjusts the opening degree of the water inlet valve to suck part of the external water into the pressure tank 426 to reduce the external water pressure; when the external water pressure is lower than the preset specific standard water pressure, the pressure tank 426 operates to gradually increase the water pressure in the pipeline to the preset standard water pressure, specifically, the pressure tank controller 428 controls the outlet valve of the pressure tank 426 and adjusts the opening of the outlet valve, so as to release the water temporarily stored in the pressure tank 426, thereby increasing the external water pressure.
As shown in fig. 5, in one embodiment, the water softening plant softening system further includes a salt suction pipe 500, and the solvent input end of the regeneration liquid mixing assembly 300 sucks the regeneration liquid through the salt suction pipe 500.
One end of the salt absorption pipe 500 absorbs the regeneration liquid, and the other end of the salt absorption pipe 500 is connected with the solvent input end of the regeneration liquid mixing assembly 300. Specifically, the number of the salt absorption pipes 500 may be multiple, that is, the solvent input end of the regeneration liquid mixing assembly 300 may absorb the regeneration liquid through multiple salt absorption pipes 500, so as to meet the requirement of a large regeneration liquid flow rate in some scenarios.
As shown in fig. 5, in one embodiment, the water softening plant softening system further includes a salt tank 600, and the solvent input end of the regeneration liquid mixing assembly 300 is connected to the salt tank 600 through a salt suction pipe 500.
The salt box 600 is used for storing regenerated salt and preparing regenerated liquid. Specifically, the salt tank 600 may be a large tank body, an opening is formed at the upper end of the tank body, the softened filter material storage container 200 is placed in the salt tank 600, and the solvent suction end of the regenerated liquid mixing assembly 300 is connected to the salt tank 600 through the salt suction pipe 500 to suck the regenerated liquid from the salt tank 600. Generally, the regeneration liquid in the salt tank 600 is a regeneration liquid (salt) having a high concentration, and the regeneration liquid having a high concentration sucked by the regeneration liquid mixing module 300 is mixed with external raw water in the regeneration liquid mixing module to form a diluted regeneration liquid, and then the diluted regeneration liquid is injected into the softened filter material storage container 200 to be exchanged and regenerated with the softened filter material 100.
As shown in FIG. 5, in one embodiment, the water softening apparatus softening system further includes a salt valve 700, and one end of the salt suction pipe 500 near the salt tank 600 is connected to the salt valve 700.
The salt valve 700 is used to control whether the solvent suction side of the regeneration liquid mixing assembly 300 can suck the regeneration liquid from the salt tank 600 through the salt suction pipe 500. When the salt valve 700 is opened, the solvent suction end of the regenerated liquid mixing assembly 300 sucks the regenerated liquid from the salt tank 600 through the salt suction pipe 500; when the salt valve 700 is closed, the solvent suction side of the regeneration liquid mixing assembly 300 cannot suck the regeneration liquid from the salt tank 600 through the salt suction pipe 500. That is, under normal conditions, when the water softening equipment softens the regeneration working condition of the system, the salt valve 700 is opened, and the regeneration liquid in the salt tank 600 enters the regeneration liquid mixing component 300 through the salt absorption pipe 500 and the solvent input end of the regeneration liquid mixing component 300 to be mixed with the raw water; when the water softening equipment softening system is in other working conditions (non-regeneration working conditions), the salt valve 700 is closed, and the regeneration liquid in the salt tank 600 cannot enter the regeneration liquid mixing assembly 300 through the salt suction pipe 500 and the regeneration liquid mixing assembly 300.
