Referring to fig. 1, a salt tank 10 of a water softener includes a tank body 110, a resin tank 130, and a salt well 140, wherein the resin tank 130 and the salt well 140 are vertically disposed in the tank body 110, an ion exchange resin is disposed in the resin tank 130, a salt valve 141 is disposed in the salt well 140, the salt valve 141 is connected with the resin tank 130 through an ejector, and a float 143 for controlling the opening and closing of the salt valve 141 is disposed in the salt valve 141. Wherein, the regeneration work flow of the water softener comprises: (1) Filling water into the salt tank 10, and gradually raising the float 143 with the rise of the liquid level in the salt tank 10 to open the salt valve 141; (2) dissolving salt particles in the salt tank 10; (3) backwashing: water is washed in from the bottom of the ion exchange resin and flows out from the top of the ion exchange resin so as to wash away dirt intercepted by the top of the ion exchange resin; (4) salt absorption (regeneration): the tap water passes through the ejector, the venturi principle is utilized, the tap water flows through the ejector to generate negative pressure, the ejector sucks up the strong brine in the salt tank 10 through the salt valve 141 and mixes the strong brine with the tap water, the obtained salt water with certain concentration regenerates ion exchange resin, in the salt sucking process, the floater 143 in the salt valve 141 gradually falls down, the salt sucking port at the bottom of the salt valve 141 has certain suction force due to the fact that the ejector generates larger negative pressure, and in the final stage of salt sucking, the floater 143 can be quickly sucked by the salt sucking port and is attached and sealed with the bottom support of the salt valve 141, and the salt valve 141 is closed; and (5) forward washing: the salt in the ion exchange resin was completely washed clean with tap water.

The water softener has a salt absorption amount deviation Δv, Δv= (s+Δs) ×Δd+Δv _{Salt particles} in the regeneration process, where s is the liquid surface area when the salt valve 141 is closed at the end of the previous round of regeneration, Δs and Δd are the amount of change in the liquid surface area when the salt valve 141 is closed at the end of the present round of regeneration (relative to the previous round) and the deviation in the liquid level height (relative to the previous round), and Δv _{Salt particles} is the amount of change in the volume of salt particles below the closed liquid surface of the salt valve 141.

The regeneration (salt absorption) process of the water softener relates to the processes of negative pressure change of the ejector, irregular movement of the floater 143, fitting of the floater 143 with a bottom bracket and the like, and is a multi-transient association process, so that the liquid level height deviation delta d caused by closing of the salt valve 141 is difficult to eliminate. The salt tank 10 of the existing water softener has a larger liquid surface area s when the salt valve 141 is closed; salt particles in the box body 110 are dissolved during regeneration, the upper salt particles move downwards, and the liquid surface area can generate a change delta s; in addition, as the salt particles dissolve, a large change in the volume of salt particles below the closed level of the salt valve 141 in the tank 110 may occur, Δv _{Salt particles} , resulting in a corresponding change in the volume of salt below the closed level of the salt valve 141. These factors lead to the salt absorption amount deviation DeltaV together to be big for ion exchange resin regeneration stability is poor, and the actual cycle softening water amount deviation of water softener is big, deviates from the design value by a wide margin, and still easily forms the salt bridge, leads to salt water concentration low, influences regeneration effect, needs to constantly turn salt tank 10 and smashes the salt bridge, and the use experience is felt poorly.

In order to solve the above technical problems, the present utility model provides a salt tank 10 having a separator structure 200, and the salt tank 10 is used for a water softener.

Referring to fig. 2, 6, 7, 11 and 12, in the embodiment of the present utility model, the salt tank 10 includes a tank body 110, a resin tank 130 (not shown), a salt well 140, a partition structure 200 and a control valve 120 (not shown), the control valve 120 includes a jet device, the resin tank 130, the salt well 140, the partition structure 200 and the jet device are all disposed in the tank body 110, wherein the resin tank 130 and the salt well 140 are vertically disposed in the tank body 110, and an ion exchange resin is disposed in the resin tank 130. In the regeneration process of the water softener, water is injected into the tank 110 to dissolve salt particles, saturated salt water is obtained, the control valve 120 is opened, tap water is introduced into the ejector, the ejector sucks the salt water in the tank 110 through the salt valve 141 and mixes the salt water with the tap water, the obtained salt water with a certain concentration regenerates the ion exchange resin, in the salt suction process, the floater 143 in the salt valve 141 gradually falls, and as the ejector generates a large negative pressure, a certain suction force exists at a salt suction port at the bottom of the salt valve 141, and in the final stage of salt suction, the floater 143 can be quickly sucked by the salt suction port and is attached and sealed with a bottom support of the salt valve 141, the salt valve 141 is closed, and the salt suction is ended.

The partition structure 200 includes a support plate 210, wherein a first opening 211 is disposed on the support plate 210, the support plate 210 has a first surface L1 and a second surface L2 disposed opposite to each other, and the first opening 211 penetrates through the first surface L1. Specifically, the first surface L1 and the second surface L2 are located on the upper and lower sides of the support plate 210, respectively, and the first opening 211 penetrates only the first surface L1, or the first opening 211 penetrates both the first surface L1 and the second surface L2. The support plate 210 is transversely disposed in the case 110, and salt particles are disposed on the support plate 210.

In an embodiment, the support plate 210 is further provided with a second opening 212, and the second opening 212 penetrates only the first surface L1, or the second opening 212 penetrates both the first surface L1 and the second surface L2, and the resin can 130 is inserted into the second opening 212, and the aperture of the second opening 212 is consistent with the outer diameter of the resin can 130.

According to the technical scheme, the partition plate structure 200 is arranged in the salt tank 10, and the partition plate structure 200 is matched with the salt well 140 in the salt tank 10, so that the deviation DeltaV of the salt absorption amount in the salt absorption process is reduced. In the solution of the present utility model, the salt well 140 is inserted into the first opening 211, the salt valve 141 directly sucks the salt water from the position corresponding to the first opening 211, the salt particles are located on the supporting plate 210, and the salt particles do not substantially enter the first opening 211, so that no salt particles exist below the closed liquid level of the salt valve 141, and the "s+Δs" and/or the "Δv _{Salt particles} " in Δv= (s+Δs) ×Δd+Δv _{Salt particles} are reduced, thereby reducing the deviation Δv of the salt absorption amount during the salt absorption process.

Specifically, referring to fig. 7, 11 and 12, in an embodiment, the first opening 211 extends at least through the first surface L1, the salt well 140 is vertically inserted into the first opening 211, and the preset closing liquid level of the salt valve 141 is lower than the first surface L1 and not lower than the second surface L2. The first opening 211 is a closed annular hole, and may specifically be a circular ring, a polygonal ring or other irregular annular structures; or the first opening 211 is a hole-shaped structure with a notch, and the first opening 211 and the case 110 are enclosed to form a closed annular hole. During regeneration of the salt suction, the liquid level in the tank 110 gradually decreases, the float 143 gradually decreases, and when the liquid level in the tank 110 decreases between the heights of the first surface L1 and the second surface L2, that is, when the liquid level in the tank 110 decreases between the upper edge of the first opening 211 and the lower edge of the first opening 211, the float 143 decreases to the salt suction port, and the salt valve 141 closes. In this embodiment, s in Δv= (s+Δs) ×Δd+Δv _{Salt particles} is the liquid surface area in the first opening 211 at the end of the previous round of regeneration (when the salt valve 141 is closed), Δs and Δd are the amount of change in the liquid surface area in the first opening 211 (or the first opening 211 and the case 110 enclose a closed annular hole) at the end of the present round of regeneration (when the salt valve 141 is closed) and the amount of change in the liquid surface height in the first opening 211 (the first opening 211 and the case 110 enclose a closed annular hole) relative to the previous round, respectively, Δv _{Salt particles} is the amount of change in the volume of salt particles below the closed liquid surface of the salt valve 141 in the first opening 211 (the first opening 211 and the case 110 enclose a closed annular hole). Since the cross-sectional area S of the first opening 211 or the cross-sectional area S of the first opening 211 and the case 110 enclosed into a closed annular hole is much smaller than the cross-sectional area S of the case 110, and since the first opening 211 or the first opening 211 and the case 110 enclosed into a closed annular hole are substantially free of salt particles, the "s+Δs" of the salt tank 10 of the present utility model is greatly reduced when the salt valve 141 is closed, and Δv _{Salt particles} is reduced to nearly zero, thereby greatly reducing the deviation Δv of the salt absorption amount of the salt tank 10.

In order to eliminate Δs when absorbing salt, in the above embodiment, further, the cross-sectional area S of the first opening 211 or the cross-sectional area S of the closed annular hole enclosed by the first opening 211 and the case 110 is maintained constant or consistent at different heights. During salt absorption, when the salt valve 141 is closed, Δs=0, and the salt absorption amount deviation Δv is further reduced.

In order to prevent salt particles above the support plate 210 from entering the first opening 211 as much as possible, the diameter of the first opening 211 is slightly larger than the outer diameter of the salt well 140, and in particular, the inner diameter of the first opening 211 is 3-10mm larger than the outer diameter of the salt well 140.

Referring to fig. 7, 8, 9 and 10, in an embodiment, in the foregoing embodiment, a diversion hole 213 is further provided on the supporting plate 210, and the diversion hole 213 and the first opening 211 penetrate through the first surface L1 and the second surface L2. The supporting plate 210 divides the interior of the case 110 into an upper chamber 110a and a lower chamber 110b which are arranged up and down, the guide hole 213 communicates the upper chamber 110a with the lower chamber 110b, the bottom of the salt well 140 penetrates the bottom of the first opening 211, and the salt well 140 communicates with the lower chamber 110 b. Salt water formed by dissolution of salt particles above the supporting plate 210 flows into the lower chamber 110b from the upper chamber 110a mainly through the diversion holes 213, the supporting plate 210 separates salt water in the lower chamber 110b from salt particles in the tank 110, the liquid level in the tank 110 gradually decreases during salt suction, and the salt valve 141 is closed when the liquid level decreases between the heights of the first surface L1 and the second surface L2, that is, when the liquid level in the tank 110 decreases between the upper edge of the first opening 211 and the lower edge of the first opening 211. In this particular embodiment, preferably, when the preset closing level h of the salt valve 141 is located at a middle position of the first surface L1 and the second surface L2, that is, the preset closing level h of the salt valve 141 is flush with the middle of the first opening 211; because the actual closing level of the salt valve 141 may deviate from top to bottom, when the wall of the first opening 211 is thin (or the wall thickness of the supporting plate 210 is small), the preset closing level h of the salt valve 141 is located at the center of the upper edge and the lower edge of the supporting plate 210, and it is easier to ensure that the actual closing level of the salt valve 141 is located at a position between the upper edge and the lower edge of the supporting plate 210, thereby ensuring that the actual closing level area of the salt valve 141 remains unchanged (i.e., Δs=0).

In the above embodiment, the wall thickness of the first opening 211 is 3-15mm, the thickness of the first hole wall may be 3mm, 8mm, 15mm or any value therebetween, and too small wall thickness of the first opening 211 is not beneficial to ensure that the actual closing liquid level of the salt valve 141 is located between the upper edge and the lower edge of the support plate 210, and too large thickness of the first opening 211 may make the support plate 210 too thick, which increases the material cost and occupies the internal space of the case 110. When the first surface L1 and the second surface L2 are parallel to the horizontal plane, the thickness of the first opening 211 is equal to the difference in height between the first surface L1 and the second surface L2.

In the above embodiment, a plurality of supporting feet 250 are disposed on one side of the second surface L2 of the supporting plate 210, and the supporting feet 250 are used to support the supporting plate 210 to be placed in the case 110. The support plate 210 is further provided with a plurality of reinforcing ribs 270 on one side of the first surface L1 and/or the second surface L2, and the number of the reinforcing ribs 270 is plural; salt particles are accumulated above the supporting plate 210, so that the supporting plate 210 needs to have better strength, and the strength of the supporting plate 210 is improved by arranging the reinforcing ribs 270 on the supporting plate 210 due to the fact that the supporting plate 210 is inconvenient to manufacture and too thick.

Referring to fig. 11, in order to facilitate the brine in the upper chamber 110a flowing into the lower chamber 110b through the diversion holes 213, the first surface L1 is preferably inclined, and the first surface L1 is preferably inclined downward toward the first opening 211. Specifically, the included angle between the first surface L1 and the horizontal plane is α, where α is not less than 2 ° and not more than 15 °. Too large a would result in too thick the support plate 210 and too small a would result in difficulty in saline flow during the final stage of salt absorption, so that the saline has not flowed down the diversion holes 213, the salt valve 141 is closed, and salt absorption is completed.

Referring to fig. 12, in another embodiment, the second surface L2 is attached to the bottom of the case 110, and the brine above the supporting plate 210 directly flows into the first opening 211. Referring to fig. 13, in this embodiment, further, the first surface L1 is inclined, and the first surface L1 is inclined downward toward the first opening 211, so as to increase the speed of the brine flowing from the support plate 210 into the first opening 211 during the salt sucking process; the angle between the first surface L1 and the horizontal plane is α, α is not smaller than 2 ° and not larger than 15 °, and similarly, α is too large, which may cause the support plate 210 to be too thick, α is too small, which may cause the brine to flow on the support plate 210 to be difficult in the final stage of salt absorption, so that the brine does not flow down from the support plate 210, the salt valve 141 is closed, and salt absorption is finished.

Referring to fig. 2, 3, 4 and 5, in another embodiment, the partition structure 200 further includes a support cup 230, the support cup 230 is disposed in the first opening 211, the support cup 230 extends in a vertical direction and has a bottom passing through the first opening 211, a through hole 231 is disposed on the support cup 230, and a lower edge of the through hole 231 is lower than the first surface L1. The supporting plate 210 divides the interior of the case 110 into an upper chamber 110a and a lower chamber 110b which are arranged up and down, the diversion hole 213 communicates the upper chamber 110a with the lower chamber 110b, the through hole 231 communicates the lower chamber 110b with the supporting cup, the salt well 140 is vertically arranged in the supporting cup 230 and is in clearance fit with the supporting cup 230, a salt valve 141 is arranged in the salt well 140, a float 143 for controlling the opening and closing of the salt valve 141 is arranged in the salt valve 141, and the preset closing liquid level of the salt valve 141 is lower than the lower edge of the through hole 231. Due to the presence of the liquid level deviation Δd, in order to ensure that the actual closed liquid level of the salt valve 141 is lower than the height of the lower edge of the through hole 231, in a specific embodiment, the preset closed liquid level h of the salt valve 141 is at least 10mm lower than the height of the lower edge of the through hole 231.

Specifically, the supporting cup 230 is a cup-shaped structure with an opening at an upper end, the through hole 231 is formed at an upper end of a sidewall of the supporting cup 230, the salt well 140 is inserted into the supporting cup 230 from above the supporting cup 230, the salt well 140 is communicated with the supporting cup 230, and the salt well 140 directly sucks the salt water from the supporting cup 230. The support cup 230 is integrally formed with the support plate 210, or the support cup 230 is separately formed with the support plate 210, and the support cup 230 is fixed at a position corresponding to the first opening 211 by a fixing member. In order to prevent salt particles above the support plate 210 from entering the support cup 230 as much as possible, the inner diameter of the opening of the support cup 230 is slightly larger than the outer diameter of the salt well 140, and in particular, the inner diameter of the opening of the support cup 230 is 3-10mm larger than the outer diameter of the salt well 140.

In this embodiment, during the salt sucking process, the liquid level in the tank 110 gradually drops, the float 143 also gradually drops, when the liquid level in the tank 110 drops to the height position of the lower edge of the through hole 231, the liquid level in the tank 110 stops dropping, the salt sucking is continued, the liquid level in the supporting cup 230 gradually drops, the float 143 continues to drop until the salt sucking cover is closed, the salt valve 141 is closed, and the salt sucking is ended. In this embodiment, s in Δv= (s+Δs) ×Δd+Δv _{Salt particles} is the liquid surface area in the cup at the end of the previous round of regeneration (when the salt valve 141 is closed), and Δs and Δd are the amount of change in the liquid surface area in the cup 230 (relative to the previous round) and the amount of change in the liquid surface height in the cup 230 (relative to the previous round) at the end of the present round of regeneration (when the salt valve 141 is closed), respectively, Δv _{Salt particles} is the amount of change in the volume of salt particles below the closed liquid surface of the salt valve 141 in the cup 230. Since the cross-sectional area S of the cup 230 is much smaller than the cross-sectional area of the case 110, and since salt particles are substantially not contained in the cup 230, "s+Δs" when the salt valve 141 is closed is reduced much, and Δv _{Salt particles} is reduced to nearly zero, so that the deviation Δv of the salt suction amount of the salt case 10 is greatly reduced.

To eliminate Δs at salt uptake, in the above embodiment, further, the cross-sectional area S of the cup 230 is maintained constant or consistent at different heights. During the salt suction, when the salt valve 141 is closed, Δs=0, Δv=s (the cup cross-sectional area) ×Δd, and the salt suction amount deviation Δv further decreases.

In the above embodiment, in order to ensure that the water injected during the regeneration can contact with the salt particles on the support plate 210, thereby allowing the salt to be dissolved to obtain saturated brine, further, the lower edge of the through hole 231 is not lower than the second surface L2, and preferably, the lower edge of the through hole 231 is flush with the second surface L2. If the lower edge of the through hole 231 is lower than the second surface L2, a larger space exists between the lower edge of the support plate 210 and the lower edge of the through hole 231, and when less water is injected into the tank 110 during the regeneration process of the water softener, the height of the liquid level in the tank 110 rises too little, and the water cannot contact with salt particles, so that the saturated brine cannot be obtained due to the inability of the salt dissolution.

In the above embodiment, a plurality of supporting feet 250 are provided on one side of the second surface L2 of the supporting plate 210, and the supporting feet 250 are used to support the supporting plate 210 to be placed in the case 110. The support plate 210 is further provided with a plurality of reinforcing ribs 270 on one side of the first surface L1 and/or the second surface L2, and the number of the reinforcing ribs 270 is plural; salt particles are accumulated above the supporting plate 210, so that the supporting plate 210 needs to have better strength, and the strength of the supporting plate 210 is improved by arranging the reinforcing ribs 270 on the supporting plate 210 due to the fact that the supporting plate 210 is inconvenient to manufacture and too thick. In a specific embodiment, the support plate 210 is disposed on one side of the first surface L1 and one side of the second surface L2, and a plurality of reinforcing ribs 270 are disposed on one side of the support plate 210, and a plurality of reinforcing ribs 270 form a plurality of rib squares, so that during the salt sucking process, the liquid level in the tank 110 gradually decreases, and when the liquid level decreases to be level with the first surface L1, the salt valve 141 continues to suck salt, and the salt water in the rib square area on the upper surface of the support plate 210 flows to the lower side of the support plate 210 through the flow guiding holes 213, and flows into the support cup 230 from the tank 110 below the support plate 210 through the through holes 231.

Referring to fig. 6, further to the above embodiment, in order to facilitate the brine in the first cavity flowing into the second cavity through the diversion hole 213, the first surface L1 is inclined. Specifically, the included angle between the first surface L1 and the horizontal plane is α, where α is not less than 2 ° and not more than 15 °. Too large a would result in too thick the support plate 210 and too small a would result in difficulty in saline flow during the final stage of salt absorption, so that the saline has not flowed down the diversion holes 213, the salt valve 141 is closed, and salt absorption is completed.
