Description

Technical Field

[0001] This utility model relates to a water softening auxiliary salt dissolving device, belonging to the technical field of water treatment equipment. Background Technology

[0002] Currently, in purified water treatment equipment, the traditional pretreatment module mainly contains a dual softener. The dual softener removes calcium and magnesium ions from the raw water, softening the water and preventing scaling on the reverse osmosis membrane, which would affect the normal operation of the reverse osmosis system. The dual softener is filled with cationic sodium resin, which exchanges ions with the calcium and magnesium ions in the raw water, displacing them. After the sodium ions in the softener are depleted, a brine system replenishes the softener with saturated brine. The sodium ions in the saturated brine again displace the adsorbed calcium and magnesium ions, and this brine is discharged outside the system during flushing, achieving softener regeneration. When the brine in the brine tank is depleted, it needs to be replenished. A large amount of particulate salt accumulating in the brine tank cannot dissolve completely and promptly in the water, potentially leading to insufficient brine concentration before the next regeneration process. This prevents complete resin regeneration and affects the hardness of the produced water.

[0003] After searching the existing technology, a Chinese patent with publication number CN218688209U was found to disclose a salt dissolving device for a sodium ion water softener. This patent uses a stirrer to achieve rapid salt dissolution, but it was found during use that the stirrer relies on a stirring paddle. The stirring paddle is immersed in salt water for a long time, which can easily lead to corrosion and other failures. This not only increases the maintenance frequency, but may also affect the long-term stable operation of the equipment. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a soft water-assisted salt dissolution device that can promote the rapid dissolution of salt particles, ensure that the brine required during the regeneration process reaches a saturated concentration, and improve the regeneration efficiency of softening resin.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a soft water-assisted salt dissolving device, comprising:

[0006] The container has an inner cavity suitable for water storage, and a salt granule inlet is provided on the upper surface of the container.

[0007] A water jet injector, which is provided with an inlet, a salt tank connection port and an outlet;

[0008] The raw water inlet pipe has one end adapted to connect to the raw water source and the other end connected to the water inlet of the water jet injector.

[0009] A water inlet control valve assembly is installed on the raw water inlet pipe between the raw water source and the water jet injector;

[0015] Furthermore, to prevent water inlet blockage, the soft water-assisted salt dissolving device also includes a salt plate, which is disposed inside the tank and divides the inner cavity of the tank into an upper salt storage chamber and a lower water storage chamber.

[0016] A connecting cylinder, which passes vertically through the salt plate and is disposed on the salt plate, has a connecting channel inside the connecting cylinder that connects the salt storage chamber and the water storage chamber;

[0017] Furthermore, to facilitate flow observation, the soft water-assisted salt dissolving device also includes a flow indicator, which is installed on a pipeline connected to the outlet of the water jet.

[0018] Furthermore, the outer sidewall of the housing is provided with an overflow port at the top and a lower outlet at the bottom;

[0019] The soft water-assisted salt dissolving device also includes a brine discharge pipe, one end of which is connected to the overflow port and the lower outlet of the tank via branches, and the other end is adapted to be connected to an external discharge port.

[0020] Furthermore, a specific structure of an intake valve assembly is provided, the intake valve assembly including a manual air circuit valve, a check valve and a pneumatic air circuit valve connected in series.

[0025] Furthermore, the soft water-assisted salt dissolving device also includes a pressure indicator, which is installed on the air inlet pipe.

[0026] By adopting the above technical solution, this utility model has the following beneficial effects:

[0027] In this invention, during use, the outlet valve is first closed, the inlet control valve group is opened, and raw water is introduced into the tank through the raw water inlet pipe via the water jet injector.

[0029] In summary, this invention makes the salt dissolution process faster, more uniform, and more efficient, effectively improving the quality of the brine required for resin regeneration and enhancing the overall system's performance and operational stability. Attached Figure Description

[0030] Figure 1 This is a schematic diagram of the structure of the water softening-assisted salt dissolving device of this utility model. Detailed Implementation

[0031] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0032] like Figure 1 As shown, a water softening-assisted salt dissolving device includes:

[0033] The tank 1 has an inner cavity suitable for water storage, and the upper surface of the tank 1 has a salt granule inlet.

[0034] Water jet 4, the water jet 4 is provided with water inlet 41, salt tank connection port 42 and water outlet 43;

[0035] Raw water inlet pipe 5, one end of raw water inlet pipe 5 is suitable for connecting to raw water source, and the other end is connected to the water inlet 41 of water jet 4.

[0036] The inlet control valve assembly is installed on the raw water inlet pipe 5 between the raw water source and the water jet 4.

[0037] Salt tank connecting pipe 6, one end of which extends through the connecting cylinder 3, and the other end is connected to the salt tank connecting port 42 of the water jet 4;

[0038] The intake pipe has one end that is suitable for connecting to an external compressed air source;

[0039] Intake valve assembly, which is installed on the intake pipe;

[0040] The jet pipe 7 has one end adapted to connect to the air intake pipe and the other end set inside the box, parallel to the upper surface of the salt plate 2. The jet pipe 7 has multiple jet holes.

[0041] The outlet valve (not shown in the figure) is located at the outlet 43 of the water jet injector 4.

[0042] In this embodiment, as Figure 1 As shown, first, the outlet valve is closed, and the inlet control valve group is opened. Raw water is introduced into the tank 1 via the raw water inlet pipe 5 and the water jet injector 4. After the liquid level reaches the set height, the inlet control valve group is closed, and the air inlet valve group is opened. Compressed air enters the jet pipe 7 through the air inlet pipe and is ejected from the jet hole to agitate and stir the salt in the tank 1, promoting the dissolution of the salt and completing the preparation of the brine. After dissolution is complete, the outlet valve is opened, and the prepared brine is discharged from the outlet 43 of the water jet injector 4. In some embodiments, the outlet valve may also be a conversion connection channel built into the water jet injector 4.

[0043] Specifically, such as Figure 1 As shown, it also includes: a salt plate 2, which is installed inside the box 1 and divides the inner cavity of the box 1 into an upper salt storage chamber and a lower water storage chamber;

[0044] The connecting cylinder 3 passes vertically through the salt plate 2 and is set on the salt plate 2. The connecting cylinder 3 has a connecting channel that connects the salt storage chamber and the water storage chamber.

[0045] Specifically, such as Figure 1 As shown, the soft water-assisted salt dissolving device also includes a flow indicator 8, which is installed on a pipeline connected to the outlet 43 of the water jet injector 4.

[0046] In this embodiment, as Figure 1 As shown, during operation, the salt particles added through the salt particle inlet accumulate in the salt storage chamber, while raw water enters the water storage chamber inside the tank 1 through the raw water inlet pipe 5 and the water jet injector 4. During the salt dissolution process, the connecting cylinder 3 creates a unidirectional flow between the salt storage chamber and the water storage chamber, meaning water can pass through the connecting cylinder 3 to the salt storage chamber. When the brine in the salt storage chamber reaches the required concentration, the raw water through the raw water inlet pipe creates negative pressure at the salt tank connection port 42 through the inlet 41 of the water jet injector 4, and finally discharges from the outlet 43. The flow rate of the discharged brine is monitored by the flow indicator 8.

[0047] The flow indicator 8 can be of various types, such as turbine flow meters or electromagnetic flow meters, and the appropriate type can be selected according to actual needs.

[0048] Specifically, such as Figure 1 As shown, the outer side wall of the housing 1 is provided with an overflow port 101 located at the top and a lower outlet 102 located at the bottom;

[0049] The soft water-assisted salt dissolving device also includes a brine discharge pipe 9. One end of the brine discharge pipe 9 is connected to the overflow port 101 and the lower outlet 102 of the tank 1 through branches, and the other end is adapted to be connected to an external discharge port.

[0050] Specifically, such as Figure 1 As shown, the water inlet control valve group includes a water inlet manual valve 131 and a water inlet pneumatic valve 132 connected in series.

[0051] Specifically, such as Figure 1 As shown, the soft water-assisted salt dissolving device also includes a liquid level sensor 14, which is installed on the inner wall of the tank 1.

[0052] Specifically, such as Figure 1 As shown, the soft water-assisted salt dissolving device also includes a control valve 16, which is installed on the salt tank connecting pipe 6 between the tank body 1 and the water jet 4.

[0053] In this embodiment, as Figure 1 As shown, during use, when resin regeneration is required, the water inlet of the raw water inlet pipe 5 is controlled by the water inlet control valve group. The pneumatic water inlet valve 132 opens, allowing raw water to enter the inlet 41 of the water jet injector 4 through the raw water inlet pipe 5. The raw water enters the tank 1 through the salt tank connection port 42 and the salt tank connection pipe 6 of the water jet injector 4, replenishing the tank 1 with water. When the liquid level in the tank 1 reaches a preset height, the pneumatic valve 113 on the air inlet pipe opens, and compressed gas enters the jet pipe 7 through the air inlet pipe. The compressed gas is ejected from multiple jet holes on the jet pipe 7, agitating the water in the salt storage chamber.

[0054] Specifically, such as Figure 1As shown, the intake valve assembly includes a manual air valve 111, a check valve 112, and a pneumatic air valve 113 connected in series.

[0055] Specifically, such as Figure 1 As shown, the soft water-assisted salt dissolving device also includes a pressure reducing valve 12, which is installed on the air inlet pipe.

[0056] Specifically, such as Figure 1 As shown, the soft water-assisted salt dissolving device also includes a pressure indicator 15, which is installed on the air inlet pipe.

[0057] In this embodiment, as Figure 1 As shown, the pressure reducing valve 12 is set to reduce pressure to 3 bar. First, close the outlet valve, open the inlet manual valve 131 and the inlet pneumatic valve 132 in the inlet control valve group, and the raw water enters the water ejector 4 through the inlet 41 of the water ejector 4 via the raw water inlet pipe 5. Then, water is added to the tank 1 through the salt tank connection port 42 and the salt tank connection pipe 6. When the liquid level sensor 14 detects that the water level has reached the set height, close the inlet control valve group, and open the air manual valve 111, the check valve 112 and the air pneumatic valve 113 in the air inlet valve group. Compressed air enters the jet pipe 7 through the air inlet pipe 10, and airflow is ejected from multiple jet holes on the jet pipe 7 to disturb and agitate the salt particles in the salt storage chamber inside the tank 1, thereby completing the brine preparation process. Once dissolution is complete, close the air inlet valve assembly and open the outlet valve. The prepared brine is then drawn from the raw water inlet pipe 5, which drives the brine tank connection port 42 of the water jet injector 4 to form a negative pressure. Finally, the brine is discharged from the outlet 43 of the water jet injector 4, and the flow rate is monitored by the flow indicator 8.

[0058] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
