The terminology used in the description herein is for describing specific embodiments only and is not intended to be limiting. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0022] Please refer to Figure 1 In one embodiment of the present application, a salt adding system of a softening water equipment for providing saturated brine for the softening water equipment 500, comprising: a salt dissolving tank 100 and a saturated water tank 200, the outlet of the salt dissolving tank 100 is connected to the inlet of the saturated water tank 200 through a filtration equipment 300, the outlet of the saturated water tank 200 is provided with a salinity detector 210, and the outlet of the saturated water tank 200 is connected to the saturated brine inlet of the softening water equipment 500 (also referred to as sodium ion exchange equipment in the present application).

[0023] The salt dissolving tank 100 is used to mix and dissolve the salt and water to reach the saturated state, and the saturated brine enters the saturated water tank 200 and is then transported to each sodium ion exchange device for use. When in use, there is always undissolved salt in the salt dissolving tank 100, that is, the solubility reaches 100%, so that there is always saturated brine flowing into the saturated water tank 200, and the saturated water tank 200 plays a role of temporary storage, and at the same time, the saturated brine is supplied to the sodium ion exchange device, that is, the softening water device 500. Compared with adding salt to each salt tank 510 every day, this centralized salt dissolving and centralized brine supply mode reduces the amount of work of adding salt and saves labor costs, and the work efficiency is high. At the same time, the salinity detector 210 of the saturated water tank 200 detects the concentration of the brine in the saturated water tank 200 in real time, so as to ensure that the brine supplied to each sodium ion exchange device is in a saturated state to meet the use of the softening water device 500. When the salinity detector 210 detects that the concentration of the brine in the saturated water tank 200 does not reach the saturated state, the valve at the outlet of the saturated water tank 200 is closed, and salt is added to the salt dissolving tank 100 to promote the salt in the salt dissolving tank 100 to be fully dissolved to the saturated brine transported into the saturated water tank 200, and the valve at the outlet of the saturated water tank 200 is opened to supply the saturated brine to the softening water device 500. The softening water device 500 is usually distributed at different positions of the production site, and only needs to transport the saturated brine in the saturated water tank 200 to each softening water device 500 through a pipeline for use, without the need to invest additional manpower to add salt to each salt tank 510 every day. At this time, the salt tank 510 of each softening water device 500 is used as a backup, and only when special circumstances such as equipment abnormalities occur, the brine in the backup salt tank 510 is used. Therefore, the salt tank 510 does not need to be frequently added with salt, and only needs to be supplemented regularly. The salt dissolving tank 100 and the saturated water tank 200 are connected through the filtering device 300, and the filtering device 300 mainly plays a role of filtering impurities and undissolved salt particles. Since the particle size of the salt particles is usually between 20 and 40 meshes, preferably, the number of meshes of the filtering device 300 is greater than 40 meshes. The filtering device 300 can be selected according to actual needs, but is not limited to ultrafiltration equipment, nanofiltration equipment, pipeline filters, filter screens and the like.

[0024] The salt dissolving tank 100 usually adds reverse osmosis water (RO water), and therefore the salt adding system of the softening water device 500 further comprises a reverse osmosis device 400, and the reverse osmosis water outlet of the reverse osmosis device 400 is connected with the water inlet 110 at the top of the salt dissolving tank 100. The RO water treated by the reverse osmosis device 400 is transported into the salt dissolving tank 100 from the water inlet 110 at the top of the salt dissolving tank 100, and then is mixed and dissolved with the salt in the salt dissolving tank 100 to form saturated brine.

[0025] Further, the side of the brine tank 100 is through with the side of the saturated water tank 200, and the side of the brine tank 100 is connected with the side of the saturated water tank 200, and the filter device 300 is arranged at the through of the side of the brine tank 100 and the side of the saturated water tank 200. In this way, the adjacent sides of the brine tank 100 and the saturated water tank 200 share a side wall, and the filter device 300 is arranged at the shared side wall, so that the structure is compact and the material cost is saved.

[0026] Since the brine tank 100 has a large volume, in order to make the salt in the tank dissolve in time, the brine tank 100 is provided with a stirrer 120. The stirrer 120 can be selected as a turbine type, a paddle type, a folding leaf type, etc. In actual use, the capacity and geometric shape of the stirrer 120 are selected according to the volume and depth of the brine tank 100.

[0027] In a more preferred embodiment, the brine tank 100 is further provided with a salt inlet 130 and a salt adding channel 140, the salt adding channel 140 is arranged obliquely, one end of the salt adding channel 140 extends into the salt inlet 130 and is movably connected with the salt inlet 130, the other end of the salt adding channel 140 is connected with a salt adding tank 150, the horizontal height of the salt adding tank 150 is higher than the horizontal height of the salt inlet 130, the salt adding channel 140 is connected with a vibration motor 160, and the vibration motor 160 drives the salt adding channel 140 to vibrate. When adding salt, workers only need to add salt into the salt adding tank 150, and the salt can slide into the brine tank 100 along the salt adding channel 140, and at the same time, the vibration motor 160 vibrates to drive the salt adding channel 140 to vibrate, so that the salt has a "spreading" action when entering the brine tank 100, which further accelerates the uniform mixing and dissolution of the salt with water, and avoids the blockage of the salt adding channel 140. In this application, the brine tank 100 and the saturated water tank 200 can be arranged below the ground, and the salt adding tank 150 is arranged on the ground, so that workers only need to stand on the ground to add salt, which avoids the inconvenience and safety hazards caused by climbing when adding salt water. Since the salt adding channel 140 vibrates under the drive of the vibration motor 160, in order to prevent the salt adding channel 140 from generating obvious axial displacement during vibration, a support can be arranged between the salt adding channel 140 and the ground to support the salt adding channel 140.

[0028] As the softening water equipment 500 is used, the saturated brine is gradually consumed, and it is necessary to supplement the RO water to the brine tank 100 for brining, so the brine tank 100 is also provided with a liquid level controller 170. Since the bottom of the brine tank 100 and the saturated water tank 200 is through, the brine tank 100 and the saturated water tank 200 form a communicating vessel, that is, the liquid level of the brine tank 100 and the saturated water tank 200 is the same, so when the liquid level controller 170 is only arranged in one of the brine tank 100 and the saturated water tank 200, the liquid level of the brine tank 100 and the saturated water tank 200 can be detected at the same time. When the liquid level is lower than the preset liquid level, the valve of the water inlet 110 is opened to supplement the RO water to the brine tank 100, and when the liquid level is higher than the preset liquid level, the valve of the water inlet 110 is closed.

[0029] In another specific embodiment of the present application, the outlet of the saturated water tank 200 is also provided with a circulating pump 220, and the outlet of the circulating pump 220 is connected with the inlet of the softening water equipment 500. The circulating pump 220 has the functions of conveying the saturated brine in the saturated water tank 200 to the softening water equipment 500, and conveying the saturated brine in the brine tank 100 to the saturated water tank 200 by the pumping action of the circulating pump 220, so that the flow of the brine can accelerate the dissolution of the salt into the saturated brine, and further ensure that the brine flowing into the softening water equipment 500 is the saturated brine. Preferably, the circulating pump 220 can be provided with at least two pumps, one of which is a standby pump, so as to avoid the influence of the pump failure on the whole system.

[0030] Further, the salt adding system of the softening water equipment 500 of the present application further comprises a recycled water pipe 600, one end of the recycled water pipe 600 is connected with the outlet of the circulating pump 220, and the other end is connected with the inlet of the brine tank 100, and the inlet of the softening water equipment 500 is connected with the recycled water pipe 600. When the saturated brine conveyed by the circulating pump 220 to the inlet of the softening water equipment 500 is not completely used, the unused saturated brine is conveyed to the brine tank 100 through the recycled water pipe 600 for recycling, so as to avoid waste. At the same time, the recycled water pipe 600 cooperates with the circulating pump 220 to make the water in the brine tank 100 flow circularly, so that the water in the brine tank 100 is disturbed, and the dissolution of the salt is accelerated.

[0031] In another specific embodiment of the present application, the top of the saturated water tank 200 is provided with an overflow pipe 230, the bottom of the saturated water tank 200 is provided with a first drain pipe 240, and the bottom of the brine tank 100 is provided with a second drain pipe 180. The outlets of the overflow pipe 230, the first drain pipe 240 and the second drain pipe 180 can be connected, and the discharged sewage and the overflowed saturated brine are collected for treatment and recycling.

[0032] The working process is that every 4 to 5 days, the worker adds salt into the salt adding box 150, the vibration motor 160 vibrates to drive the salt adding channel 140 to vibrate, at this time, the salt is "scattered" into the salted water tank 100, and the stirrer 120 stirs to accelerate the dissolution of the salt. When the liquid level in the salted water tank 100 is lower than the preset liquid level, the valve of the water inlet 110 is opened to supplement the RO water to the salted water tank 100. The salt in the salted water tank 100 is always kept in excess, that is, there is still undissolved salt, which ensures that the salt water flowing into the saturated water tank 200 is saturated salt water. The circulating pump 220 delivers the saturated salt water in the saturated water tank 200 to the softening water device 500, and the water pumping of the circulating pump 220 can also accelerate the rapid dissolution of the salt. The salinity detector 210 of the saturated water tank 200 detects the salt water concentration in the saturated water tank 200 in real time, ensures that the salt water supplied to each sodium ion exchange device is in a saturated state to meet the use of the softening water device 500. In this way, the centralized salt centralized salt water supply mode does not need to add salt frequently, and one salt adding can be used for 4 to 5 days, which reduces the salt adding workload, saves the labor cost, and can simultaneously supply saturated salt water to multiple softening water devices 500, and the working efficiency is high.

[0033] The above only discloses the preferred embodiments of the utility model, of course, cannot limit the scope of the utility model, and the person skilled in the art can understand that the whole or part of the above-mentioned embodiments can be implemented, and equivalent changes made according to the utility model claims still belong to the scope covered by the utility model.
