Description

Technical Field

[0001] The present application relates to the technical field of water softener equipment, and in particular to a water softener system and water softener equipment. Background Art

[0002] Water contains hardness ions such as calcium and magnesium. The impact of hardness ions on daily use includes poor washing effect, reduced thermal efficiency after scaling of pipe walls, and skin irritation. Water softeners can use ion exchange resins to replace hardness ions in water, thereby effectively removing hardness ions in water and softening water. The replacement capacity of ion exchange resins is limited. When the resin fails, it needs to be regenerated with the help of high-concentration salt water.

[0003] The salt concentration of the regeneration salt solution of conventional water softeners is controlled by siphoning. However, the siphoning method (diluting saturated salt water to a specific concentration) is greatly affected by water pressure fluctuations. Therefore, the regeneration parameters of the whole machine are not fixed during operation, and the corresponding softening performance of the whole machine will change. Utility Model Content

[0053] In one embodiment, Figure 1 As shown, a soft water system is provided, including: a controller, a resin container 120, a constant pressure siphon regeneration device 130 and a water circuit control valve.

[0054] The water inlet and outlet of the resin container 120 and the water inlet of the constant pressure siphon regeneration device 130 are connected to the water inlet of the soft water system. The water outlet of the constant pressure siphon regeneration device 130 is connected to the water outlet of the resin container 120. The water outlet of the resin container 120 is connected to the water production port of the soft water system, and the water inlet of the resin container 120 is connected to the sewage port of the soft water system. The water circuit control valve is set at each water circuit connection of the soft water system, and the controller is respectively connected to the constant pressure siphon regeneration device 130 and the water circuit control valve.

[0055] The controller is used to control the start-up of the constant pressure siphon regeneration device 130 and the working state of the water circuit control valve in the regeneration mode, so as to generate brine with a target concentration through the constant pressure siphon regeneration device 130, and drive the brine to flow in the resin container 120 in reverse and then be discharged through the sewage outlet.

[0056] Specifically, the working state of the water circuit control valve includes an open state and a closed state, and the working state of the water circuit control valve is used to determine the specific direction of the water circuit in the soft water system. It should be noted that the specific control method of the water circuit control valve on the direction of the water circuit can be determined according to the type of water circuit control valve in the actual application scenario and the setting position in the water circuit, which is not limited here.

[0057] In a specific embodiment, the constant pressure siphon regeneration device 130 in this embodiment is a regeneration salt solution generating device to which a water pump 137 is added as a water inlet driving force for the siphon device 133. In a specific embodiment, the constant pressure siphon regeneration device 130 can be used to generate salt water with a target concentration and provide a certain water pressure for the salt water so that the salt water flows to the resin container 120.

[0058] In actual application, this embodiment can effectively overcome the problem of unstable water pressure in the siphon device by adding a constant pressure siphon regeneration device 130 to the soft water system, and provide a fixed concentration of regeneration salt solution for the resin container 120 of the soft water system, thereby greatly improving the regeneration stability and regeneration efficiency of the ion exchange resin in the resin container 120.

[0059] In one embodiment, Figure 1 As shown, the soft water system further includes: a pre-filter 110 , and the water circuit control valve includes a water inlet valve 140 , a water production valve 150 , a sewage valve 160 and a backwash valve 170 .

[0060] The water inlet of the pre-filter 110 is used to access raw water, the water outlet of the pre-filter 110 is connected to the water inlet of the resin container 120 through the water inlet valve 140, the water outlet of the pre-filter 110 is also connected to the water outlet of the resin container 120 through the backwash valve 170, the water outlet of the pre-filter 110 is also connected to the water outlet of the resin container 120 through the constant pressure siphon regeneration device 130, the water outlet of the resin container 120 is also connected to the water production port of the soft water system through the water production valve 150, and the water inlet of the resin container 120 is connected to the sewage outlet of the soft water system through the sewage valve 160.

[0061] Specifically, the pre-filter 110 in this embodiment is used to filter large particles in the raw water, such as mud, hair, etc., to preliminarily intercept the water entering the soft water system and ensure the softening efficiency of the soft water system.

[0062] The resin container 120 in this embodiment is used to load ion exchange resin, and includes a water inlet, a water outlet, and an interception net arranged at the water inlet and the water outlet of the resin container 120. It should be noted that the resin container 120 in this embodiment is placed in a lying manner, that is, inside the tank body, the water flow direction is parallel to the ground and flows in a horizontal direction. Compared with the conventional water softener water flow direction perpendicular to the ground, the resin container 120 in this embodiment is flatter and does not occupy height space, thereby effectively reducing the size of the water softener equipment.

[0063] In addition, the resin container 120 in this embodiment may include only one layer of resin flow channel, so that the tank body flow channel is a single straight-line flow channel. The resin container 120 in this embodiment may also include multiple layers of resin flow channels, and the flow channels are separated by partitions. The resin container 120 may also directly separate the flow channels by bending and splicing the tank body. In a preferred embodiment, the resin container 120 of this embodiment uses a multi-layer resin flow channel structure, which can effectively increase the effective contact distance between water and resin, thereby improving the softening performance of the soft water system.

[0064] The water inlet valve 140, the water production valve 150, the sewage valve 160 and the backwash valve 170 in this embodiment can all be electromagnetic valve switches. It should be noted that this embodiment does not limit the specific form of the switch valve, and can be configured according to the needs of the actual application scenario. For example, the water inlet valve 140 and the backwash valve 170 can also be a one-position two-way electromagnetic valve, including a water inlet and two water outlets, and the two water outlets are respectively connected to the water inlet and the water outlet of the resin container 120.

[0065] The controller is respectively connected to the constant pressure siphon regeneration device 130 , the water inlet valve 140 , the water production valve 150 , the sewage valve 160 and the backwash valve 170 .

[0066] The controller is used to control the constant pressure siphon regeneration device 130 to start in the regeneration mode, control the water inlet valve 140 to close, the water production valve 150 to close, the backwash valve 170 to close, and the sewage valve 160 to open, so as to generate brine with a target concentration through the constant pressure siphon regeneration device 130, and drive the brine to flow in the resin container 120 in reverse and then discharge it through the sewage valve 160.

[0067] In a specific embodiment, the soft water system mainly includes a water production mode and a regeneration mode. In the water production mode, the soft water system is used to soften the raw water through the resin container 120 to obtain soft water after removing the hardness ions. In the regeneration mode, the soft water system is used to regenerate the ion exchange resin in the resin container 120 through salt water with a certain concentration.

[0068] This embodiment adds a constant pressure siphon regeneration device 130 to the soft water system, adds a water pump 137 to the water inlet of the siphon device 133, provides water inlet power for the siphon device 133, so that the water flows into the siphon device 133 according to a certain driving force, so that the siphon device 133 stably produces a siphon effect, draws a certain amount of high-concentration salt solution from the salt tank 132, and generates salt water with a target concentration, which effectively improves the abnormal phenomenon in the prior art that the siphon device is affected by water pressure fluctuations, resulting in unstable concentration of the generated salt water. In addition, the soft water system provided by this embodiment has a simpler structure, can efficiently realize the generation of salt water, and effectively improves the utilization efficiency of the regenerated salt and the regeneration efficiency of the ion exchange resin.

[0069] In one embodiment, Figure 2As shown, the constant pressure siphon regeneration device 130 includes a water tank 131, a salt tank 132, a siphon device 133, a first water replenishment valve 134, a second water replenishment valve 135, a salt solution valve 136 and a water pump 137, wherein the water outlet of the pre-filter 110 is connected to the salt tank 132 via the first water replenishment valve 134, and the water outlet of the pre-filter 110 is connected to the water tank 131 via the second water replenishment valve 135. The water outlet of the water tank 131 is connected to the first opening of the siphon device 133 via the water pump 137, the second opening of the siphon device 133 is connected to the water outlet of the resin container 120, and the third opening of the siphon device 133 is connected to the salt intake port 1322 of the salt tank via the salt solution valve 136.

[0070] Specifically, the salt box 132 includes a porous support plate 1321 and a salt suction port 1322. The porous support plate 1321 is arranged at a preset distance from the bottom of the salt box 132. The porous support plate 1321 and the side of the salt box 132 form a regeneration salt storage area for storing regeneration salt. Figure 2 As shown, the regenerated salt storage area is the area above the porous support plate 1321. It should be noted that the porous support plate 1321 in this embodiment is arranged horizontally and is sealed and connected to the side of the salt box 132 to ensure the stability of the porous support plate 1321. It should be noted that the sealed connection in this embodiment can be sealed by glue sealing, welding sealing, sealing ring sealing, etc., or be formed integrally with the container. This embodiment does not limit the specific arrangement of the porous support plate 1321.

[0071] The porous support plate 1321 and the bottom of the salt box 132 form a saturated salt solution area, and the saturated salt solution area is used to store the target salt solution. Figure 2 As shown, the saturated salt solution area is the area below the porous support plate 1321.

[0072] The salt suction port 1322 is disposed at the bottom of the saturated salt solution area, and the salt suction port 1322 is connected to the third opening of the siphon device 133 through the salt solution valve 136 .

[0073] Specifically, the aperture of the third opening of the siphon device 133 provided in this embodiment is larger than the aperture of the first opening, and the aperture of the first opening is larger than the aperture of the second opening. The aperture relationship of each opening of the siphon device 133 is to achieve a siphon effect. Water from the first opening enters the siphon device 133 according to the driving force provided by the water pump 137, and the second opening absorbs high-concentration salt water from the salt absorption port 1322 through the siphon effect, and finally outputs salt water with a target concentration through the third opening.

[0074] Specifically, the actual size parameters of the opening apertures of the first opening, the second opening, and the third opening may be determined according to the water flow rate to be achieved in the actual application scenario, and this embodiment does not limit the size parameters of the opening apertures.

[0075] In the actual control process, the controller controls the water pump 137 to start, and when the brine valve 136 is opened, the water in the water tank 131 flows to the first opening according to the preset flow parameters, and the target brine in the brine tank 132 flows to the second opening through the brine suction port 1322, and the third opening of the siphon device 133 outputs brine with a target concentration.

[0076] When the controller starts the water pump 137 and closes the saline valve 136 , the water in the water tank 131 flows to the first opening according to the preset flow parameters, and the third opening of the siphon device 133 outputs the water.

[0077] This embodiment provides a constant pressure siphon regeneration device 130 that can stably generate salt water with a target concentration, effectively overcoming the water pressure fluctuation of the siphon device, generating a siphon effect through stable water pressure, thereby effectively improving the stability and accuracy of the soft water system in generating salt solution.

[0078] In one embodiment, the regeneration mode includes a backwashing stage, a salt absorption regeneration stage, and a slow wash stage.

[0079] During the backwashing stage, the controller controls the constant pressure siphon regeneration device 130 to be closed, the water inlet valve 140 to be closed, the water production valve 150 to be closed, the backwash valve 170 to be opened, and the sewage valve 160 to be opened, so that the water filtered by the pre-filter 110 flows in the resin container 120 in the reverse direction, and the sewage generated by the backwashing resin container 120 is output through the sewage valve 160.

[0080] Specifically, this embodiment controls the soft water system to complete the backwash stage before the salt absorption regeneration stage, thereby providing an environment more conducive to the contact between the ion exchange resin and the salt solution during the salt absorption regeneration stage, so that the ion exchange resin can fully contact the salt solution.

[0081] During the salt absorption regeneration stage, the controller controls the constant pressure siphon regeneration device 130 to start, controls the water inlet valve 140 to close, the water production valve 150 to close, the backwash valve 170 to close, and the sewage valve 160 to open, so as to generate brine with a target concentration through the constant pressure siphon regeneration device 130, and drives the brine to flow in the resin container 120 in the reverse direction and then discharge it through the sewage valve 160.

[0082] Specifically, during the salt absorption regeneration stage, the soft water system will generate brine with a preset concentration, and control the brine to enter from the water outlet of the resin container 120 and flow out from the water inlet of the resin container 120, so that the salt solution flows through the pipes and surface of the ion exchange resin in the resin container 120, so that the regenerated salt contacts the ion exchange resin, thereby realizing the regeneration of the ion exchange resin.

[0083] During the slow washing stage, the controller controls the constant pressure siphon regeneration device 130 to start, controls the water inlet valve 140 to close, the water production valve 150 to close, the backwash valve 170 to close, and the sewage valve 160 to open, so as to output water through the constant pressure siphon regeneration device 130, and drive the water to flow in the resin container 120 in the reverse direction before being discharged through the sewage valve 160.

[0084] Specifically, in the slow washing stage, the soft water system controls the water body to bypass the salt box 132, enter the resin container 120 from the water outlet again, and flow out from the water inlet of the resin container 120, so as to utilize the regeneration salt remaining in the soft water system at the salt dissolving regeneration station to fully regenerate the ion exchange resin in the resin container 120, and make full use of the regeneration salt in the water pipeline to reduce the waste of regeneration salt.

[0085] In one embodiment, in the water production mode, the controller controls the constant pressure siphon regeneration device 130 to be closed, controls the water inlet valve 140 to be opened, the water production valve 150 to be opened, the backwash valve 170 to be closed, and the sewage valve 160 to be closed, so that the water filtered by the pre-filter 110 flows forward in the resin container 120, and the water softened by the resin container 120 is output through the water production valve 150.

[0086] Specifically, in the water production mode, the raw water is first preliminarily purified by the pre-filter 110 to obtain filtered water. At this time, the controller controls the water inlet valve 140 and the water production valve 150 to open, and other switch components to close, so that the filtered water that has undergone preliminary purification flows into the resin container 120 from the water inlet of the resin container 120, and flows along the resin flow channel arranged laterally in the resin container 120. The ion exchange resin fully softens the water, and the softened water is discharged from the water outlet of the resin container 120, flows out to the water outlet of the soft water system through the water production valve 150, and outputs the water softened by the resin container 120.

[0087] This embodiment uses a resin container 120 with a resin flow channel arranged horizontally, which can effectively extend the contact area between the ion exchange resin and water in the resin container 120, thereby greatly improving the softening ability of the soft water system for water bodies and providing better quality soft water.

[0088] In one embodiment, the water tank 131 includes a first liquid level switch 1311 , which is disposed at a preset distance from the top of the water tank 131 , and the controller is connected to the first liquid level switch 1311 to obtain a first liquid level in the water tank 131 .

[0089] When the first liquid level is less than the first liquid level threshold, the controller controls the first water replenishment valve 134 to open until the first liquid level is greater than or equal to the first liquid level threshold.

[0090] Specifically, in this embodiment, water can be replenished at any stage for the water tank 131. When the first liquid level switch 1311 feeds back a liquid level signal to the controller, it indicates that the first liquid level in the water tank 131 is greater than or equal to the first liquid level threshold, and at this time, the first water replenishment valve 134 can be controlled to close to stop replenishing water to the water tank 131.

[0091] In one embodiment, the salt box 132 includes a second liquid level switch 1323 , which is disposed close to the porous support plate 1321 and spaced a preset distance from the porous support plate 1321 . The controller is connected to the second liquid level switch 1323 to obtain a second liquid level in the salt box 132 .

[0092] When the second liquid level is less than the second liquid level threshold, the controller controls the second water replenishment valve 135 to open until the second liquid level is greater than or equal to the second liquid level threshold.

[0093] Specifically, in this embodiment, water can be replenished to the salt box 132 at any stage. Preferably, after the slow washing stage is completed, the second water replenishment valve 135 is controlled to open to replenish the salt box 132 with water.

[0094] When the second liquid level switch 1323 feeds back a liquid level signal to the controller, it indicates that the second liquid level in the salt tank 132 is greater than or equal to the second liquid level threshold. At this time, the second water replenishment valve 135 can be controlled to close to stop replenishing water to the salt tank 132 .

[0095] In one embodiment, the resin container 120 includes a preset number of resin channels, and the water flow direction in the resin channels is horizontal.

[0096] In a specific embodiment, the resin container 120 in this embodiment is placed in a lying manner, and the resin container 120 can adopt a structure including only one layer of resin flow channel, or a structure including multiple layers of resin flow channels. It should be noted that the length of a single layer of resin flow channel in the resin container 120 with multiple layers of resin flow channels is shorter than the length of a single layer of resin flow channel in the resin container 120 with a single layer of resin flow channel structure.

[0097] In this embodiment, the flow channel of the resin container 120 can be separated by setting a partition plate, so as to achieve a longer resin flow channel within a fixed tank size, which can further improve the exchange rate between the resin and the hardness ions in the water body, and effectively improve the softening ability of the needle water softening system on the water body.

[0098] In one embodiment, the soft water system further includes a water supply valve 180 , wherein the water outlet of the pre-filter 110 is connected to the water outlet of the soft water system through the water supply valve 180 .

[0099] When the controller is in the water production mode, the water supply valve 180 is controlled to be closed; when the controller is in the regeneration mode, the water supply valve 180 is controlled to be opened.

[0100] In a specific embodiment, the controller can also keep the water supply valve 180 open in the regeneration mode to ensure that the soft water system can continuously supply water to the water outlet to avoid affecting the normal water supply process of the water softener. It should be noted that the water supplied by the soft water system at this time is water that has been preliminarily purified by the pre-filter 110.

[0101] In summary, the present embodiment provides a soft water system. By providing a constant pressure siphon regeneration device, the problem of the siphon device being affected by water pressure fluctuations when generating the target saline solution is effectively solved. The system can stably generate brine with a target concentration and adopts a horizontally arranged resin container to effectively increase the contact area between the ion exchange resin and the brine, thereby greatly improving the resin regeneration capacity of the soft water system and effectively improving the utilization rate of the regenerated salt, thereby avoiding the waste of regenerated salt and preventing the damage to the environment by high-concentration brine.
