[0031] Figures 1 to 4 The present invention illustrates a double-layer resin tank 100 provided in one embodiment, comprising a first tank body 110, a second tank body 120, a tank body cover 130, a first water distributor 140, and a second water distributor 150.
[0032] like Figure 2 and Figure 3 As shown, the first tank 110 includes a first resin cavity 111 for containing the first resin, and the first tank 110 has a first tank opening 112 and a second tank opening 113 at both ends. The entire inner cavity of the first tank 110 is the first resin cavity 111.
[0033] The second tank 120 includes a tank cavity (not shown in the figure) for accommodating the first tank 110 and a second resin cavity 121 for accommodating the second resin. A first end A1 of the second tank 120 has a third tank opening 122, while the second end A2 of the second tank 120 is not open. The third tank opening 122 surrounds the first tank opening 112. The inner cavity of the second tank 120 is divided into the tank cavity and the second resin cavity 121. In this embodiment, the tank cavity and the second resin cavity 121 are integral. In other embodiments of this invention, a tank cavity with walls can be specifically provided to accommodate the first tank 110.
[0034] In this invention, the first resin and the second resin can be the same or different.
[0035] In this embodiment, both the first tank 110 and the second tank 120 are cylindrical. In other embodiments of this invention, the first tank 110 and the second tank 120 may also have other structures, such as triangular prisms, square prisms, etc. In this embodiment, the first tank 110 and the second tank 120 are coaxial cylinders; in other embodiments of this invention, the first tank 110 and the second tank 120 may also be coaxial.
[0036] Optionally, the cross-sectional area of the first resin cavity is S1, and the cross-sectional area of the second resin cavity is S2, where 0.7 × S2 ≤ S1 ≤ 1.3 × S2. In this embodiment, as... Figure 4 As shown, the radius of the inner cavity of the first tank 110 is R1, the radius of the inner cavity of the second tank 120 is R2, and the cross-sectional area S1 of the first resin cavity is equal to Ignoring the 110mm wall thickness of the first tank, S2 equals The cross-sectional area of the inner and outer double-layered resin chamber is designed in a certain proportion, which is conducive to increasing the water purification flow rate.
[0037] Optionally, the height-to-diameter ratio of the first tank is HD1, and the height-to-diameter ratio of the second tank is HD2, where 5 ≤ (HD1 + HD2) ≤ 12. In this embodiment, as shown... Figure 3 and 4As shown, HD1 equals H / 2R1, and HD2 equals H / 2R2. The nested design of the inner and outer double layers of this invention greatly increases the height-to-diameter ratio of the resin tank and extends the water path of the resin. Compared with traditional resin tanks, it greatly improves the flow rate of the resin tank while maintaining the same performance.
[0038] The can cover 130 is provided on the third can opening 122, including the first cover opening 131 and the second cover opening 132.
[0039] The first water distributor 140 includes a first portion 141 and a second portion 142 connected together. The first portion 141 covers the opening 112 of the first tank body, and the first resin cavity 111 is connected to the opening 131 of the first cover body through the first portion 141. A first water distribution cavity B1 is formed between the first water distributor 140 and the tank cover 130. The first water distribution cavity B1 is connected to the opening 132 of the second cover body and is connected to the second resin cavity 121 through the second portion 142. The first portion 141 and the second portion 142 are permeable to water but impermeable to resin, allowing water to pass through while preventing resin from passing through. In this embodiment, the central portion of the first portion 141 has an opening, which is connected to the opening 131 of the first cover body. In other embodiments of this utility model, this opening may be omitted.
[0040] The second water distributor 150 includes a third part 151 and a fourth part 152 connected together. A second water distribution chamber B2 is formed between the second water distributor 140 and the second end A2 of the second tank 120. The third part 151 covers the opening 113 of the second tank. The second water distribution chamber B2 is connected to the first resin chamber 111 through the third part 151 and to the second resin chamber 121 through the fourth part 152. The third part 151 and the fourth part 152 are also permeable to water but impermeable to resin, allowing water to pass through while preventing resin from passing through.
[0041] In this embodiment, the first water distributor 140 and the second water distributor 150 have identical structures. Optionally, the water distribution areas of the first water distributor 140 and the second water distributor 150 are matched with the areas of the first end A1 and the second end A2 of the second tank 120, respectively, so that they can be sealed with the second tank 120 and the water purification effect is improved.
[0042] Optionally, the first portion 141 and the second portion 142 include a first filter screen, and the third portion 151 and the fourth portion 152 include a second filter screen. Further optionally, the first and second filter screens have a mesh size of 80-150 mesh, respectively. The filter screens allow water to pass through but isolate the resin.
[0043] In this embodiment, as Figure 2As shown, the second part 142 and the fourth part 152 each include an outer frame a and a rib support b, and the first filter screen and the second filter screen respectively cover the plane formed by the outer frame a and the rib support b. This structure improves the rigidity of the water distributor. In other embodiments of this utility model, the structure of the second part 142 and the fourth part 152 may also be different.
[0044] In this embodiment, both the first water distributor 140 and the second water distributor 150 are flat water distributors, exhibiting excellent water distribution performance. In other embodiments of this utility model, water distributors with other structures may also be used.
[0045] Figure 5 and Figure 6 for Figure 1 The diagram shows the water system of the double-walled resin tank 100. Figure 5 This is a water circuit diagram showing the water supply status. Figure 6 This is a waterway diagram for the regeneration state.
[0046] like Figure 5 As shown, during water production, tap water enters the first water distribution chamber B1 through the second cover opening 132, then enters the second resin chamber 121 through the second part 142, then enters the second water distribution chamber B2 through the fourth part 152, then enters the first resin chamber 111 through the third part 151, and finally enters the first cover opening 131 through the opening on the first part 141, and finally flows out of the resin tank 100.
[0047] The water circuit during regeneration is the reverse of the water circuit during water production, such as... Figure 6 As shown, the brine enters the first cover opening 131, then enters the first resin chamber 111 through the opening on the first part 141, then enters the second water distribution chamber B2 through the third part 151, then enters the second resin chamber 121 through the fourth part 152, then enters the first water distribution chamber B1 through the second part 142, and finally flows out of the resin tank 100 from the second cover opening 132.
[0048] This utility model features an innovative resin tank structure. The resin tank adopts an inner and outer nested structure with water distributors installed at the top and bottom. This innovative layout greatly extends the water flow path of the resin tank, significantly improving the utilization rate of the resin and the water softening effect.
[0049] This invention also provides a water softening device, including the aforementioned double-walled resin tank. The water softening device provided by this invention has an excellent water softening effect.
[0050] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
