Description

Technical Field

[0001] This utility model relates to the field of water purification technology, specifically a water softener. Background Technology

[0002] A water softener is an ion exchange device that uses sodium-type cation exchange resin to remove calcium and magnesium ions from water, reducing the hardness of the raw water and thus softening it. This prevents scale formation from carbonates in pipes, containers, and boilers, significantly reducing investment costs while ensuring smooth production. It is currently widely used in the circulating water supply of various steam boilers, hot water boilers, heat exchangers, steam condensers, air conditioners, direct-fired turbines, and other equipment and systems. It is also used for domestic water treatment, industrial water treatment in food, electroplating, pharmaceutical, chemical, printing and dyeing, textile, and electronics industries, and as a pretreatment step in desalination systems. Water hardness can be significantly reduced after treatment by a single-stage or multi-stage water softener.

[0003] Regarding the aforementioned technologies, the applicant proposes a water softener where, during operation, hard water flows into a tank containing ion exchange resin. Sodium ions on the resin exchange with calcium and magnesium ions in the water, causing the resin to adsorb the calcium and magnesium ions, thus reducing the hardness of the outflowing water and completing the softening process. When the sodium ions on the resin are depleted, a regeneration process needs to be initiated. At this time, brine is injected into the tank, utilizing the sodium ion concentration difference to displace the adsorbed calcium and magnesium ions from the resin, which are then discharged with the waste liquid, restoring the resin's softening capacity and allowing it to be reused. However, the operation of the water softener relies on a brine tank for salt supply. When the salt in the brine tank is depleted, manual refilling is required, which can cause the water softener to temporarily shut down, reducing the device's efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a water softener that solves the problem mentioned in the background art where, after the salt in the salt tank is used up, the operator needs to manually add salt to the salt tank, which causes the water softener to shut down briefly and reduces the efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water softener, comprising a support base and a feeding mechanism, wherein the feeding mechanism is disposed at the top of the support base, and the feeding mechanism includes a support frame disposed at the top of the support base, a fixing frame disposed on one side of the support frame near the center point inside the support base, a storage box disposed inside the fixing frame, a storage hopper disposed above the storage box, a discharge pipe disposed at the bottom of the storage hopper, a drive motor disposed at one end of the storage box, a transmission shaft disposed at the output end of the drive motor, the drive motor driving the transmission shaft to rotate, a feeding disc disposed outside the transmission shaft, and a discharge groove evenly distributed inside the feeding disc.

[0006] By adopting the above technical solution, the inside of the salt tank can be observed through the observation window. When the salt inside the salt tank is low, the drive motor is started by the control switch. Through the transmission shaft, the feeding plate can be rotated, and the salt blocks in the discharge chute below the feeding plate can be discharged into the salt tank through the discharge pipe. At this time, the salt blocks in the storage hopper fall into the discharge chute above the feeding plate. After the discharge chute is full, the chemical inside the discharge chute can be discharged by rotating the feeding plate. Thus, the salt inside the salt tank can be added automatically, minimizing the need for the water softener to stop and improving the working efficiency of the device.

[0007] Preferably, a salt tank is provided at the top of the support base near the support frame, and an observation window is provided on one side of the salt tank.

[0008] By adopting the above technical solution, the amount of salt inside the salt tank can be directly monitored through the observation window on the salt tank.

[0009] Preferably, a resin tank is provided at the top end of the support base away from the observation window, a control valve is provided at the top of the resin tank, a water outlet pipe is provided at the top of the control valve, a water inlet pipe is provided on one side of the control valve, and a sewage discharge pipe is provided at the top end of the control valve away from the observation window.

[0010] By adopting the above technical solution, hard water flows into the resin tank containing ion exchange resin through the inlet pipe. Sodium ions on the resin exchange with calcium and magnesium ions in the water. The calcium and magnesium ions are adsorbed by the resin, thereby reducing the hardness of the outflowing water and completing the softening process. The softened water is discharged through the outlet pipe.

[0011] Preferably, the salt tank is located directly below the storage tank, and the discharge pipe is inserted into the interior of the salt tank.

[0012] By adopting the above technical solution, salt blocks can be conveniently transported into the interior of the salt tank.

[0013] Preferably, a salt suction pipe is provided at the end of the salt tank near the resin tank, and the end of the salt suction pipe away from the salt tank is inserted into the interior of the resin tank.

[0014] By adopting the above technical solution, the brine inside the salt tank can be injected into the resin tank through the brine suction pipe.

[0015] Preferably, the top of the storage bin is provided with a bin cover, and the top of the bin cover is provided with a handle.

[0016] By adopting the above technical solution, the salt blocks inside the storage tank can be easily protected.

[0017] Preferably, the drive motor is provided with a protective shell on its outer side, and the drive shaft is inserted into the discharge pipe.

[0018] By adopting the above technical solutions, the drive motor can be easily protected, and its service life can be extended.

[0019] Preferably, there are four sets of discharge troughs, which are symmetrically distributed about the drive shaft.

[0020] By adopting the above technical solution, the salt blocks can be transported conveniently.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] Equipped with a support base, feeding mechanism, observation window, and feeding tray, the salt tank can be monitored through the observation window. When the salt level is low, the drive motor is activated by a control switch. Through the transmission shaft, the feeding tray rotates, discharging salt blocks from the discharge trough below the feeding tray into the salt tank via the discharge pipe. Meanwhile, salt blocks from the storage hopper fall into the discharge trough above the feeding tray. Once the discharge trough is full, the remaining chemicals are discharged through the rotation of the feeding tray. This automatic replenishment of salt into the tank minimizes downtime for the water softener and improves the device's efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1 to 4 This embodiment provides a technical solution: a water softener, including a support base 6 and a feeding mechanism 8. The feeding mechanism 8 is disposed at the top of the support base 6. The feeding mechanism 8 includes a support frame 802 fixedly connected to the top of the support base 6. The support frame 802 can provide load-bearing capacity. A fixing frame 804 is fixedly connected to the side of the support frame 802 near the center point inside the support base 6. A storage tank 805 is fixedly connected inside the fixing frame 804. The storage tank 805 can conveniently store salt blocks.

[0031] A storage hopper 808 is fixedly connected to the upper part of the storage box 805, and a discharge pipe 809 is fixedly connected to the bottom of the storage hopper 808. A drive motor 806 is installed at one end of the storage box 805. The drive motor 806 works on the principle that a current-carrying conductor moves under the force of a magnetic field. The stator generates a magnetic field, and the coils on the rotor become current-carrying conductors after being energized. They are subjected to Ampere force in the magnetic field, generating torque and causing the rotor to rotate. At the same time, the commutator continuously changes the direction of the coil current to ensure that the rotor rotates continuously in the same direction. When selecting the drive motor 806, the appropriate model should be selected according to the actual needs. All the components required in the drive motor 806 are existing technologies and will not be described in detail below.

[0032] The output end of the drive motor 806 is provided with a transmission shaft 810. The drive motor 806 drives the transmission shaft 810 to rotate. The outside of the transmission shaft 810 is provided with a feeding plate 812. The inside of the feeding plate 812 is evenly provided with discharge troughs 811. There are four sets of discharge troughs 811. The discharge troughs 811 are symmetrically distributed about the transmission shaft 810, which can facilitate the conveying of salt blocks. The top of the support base 6 is provided with a salt box 803 near the support frame 802. An observation window 801 is provided on one side of the salt box 803. The amount of salt inside the salt box 803 can be directly monitored through the observation window 801 on the salt box 803.

[0033] The salt tank 803 is located directly below the storage tank 805. The discharge pipe 809 is inserted into the salt tank 803 to facilitate the transport of salt blocks into the salt tank 803. The top of the storage tank 805 is provided with a cover 807 to protect the inside of the storage tank 805. The top of the cover 807 is provided with a handle. The drive motor 806 is provided with a protective shell to protect the drive motor 806. The drive shaft 810 is inserted into the discharge pipe 809.

[0034] The overall effect of this embodiment is as follows: the salt level inside the salt tank 803 can be directly monitored through the observation window 801 on the salt tank 803. When the salt level is observed to be lower than a set threshold, the drive motor 806 is started by a control switch. The power of the drive motor 806 is transmitted to the feeding plate 812 through the transmission shaft 810, causing it to start rotating. The surface of the feeding plate 812 is evenly distributed with discharge grooves 811. During the rotation, the salt blocks in the discharge grooves 811 located below the feeding plate 812 fall smoothly into the salt tank 803 through the discharge pipe 809 under the action of gravity. At the same time, the salt blocks in the storage hopper 808 are automatically filled into the empty discharge grooves 811 above the feeding plate 812. Once the discharge trough 811 is full, the newly filled salt blocks will be transported to the discharge pipe 809 and discharged as the feeding plate 812 continues to rotate. This cycle is repeated to achieve automatic salt addition to the salt tank 803, which minimizes the need for water softener shutdowns due to manual salt addition and significantly improves the continuous working efficiency and operational stability of the device.

[0035] Example 2

[0036] A resin tank 5 is installed at the top of the support base 6, away from the observation window 801, which facilitates water softening. A control valve 2 is installed at the top of the resin tank 5, and an outlet pipe 1 is installed at the top of the control valve 2. An inlet pipe 3 is installed on one side of the control valve 2. A drain pipe 4 is installed at the end of the control valve 2 away from the observation window 801. A salt suction pipe 7 is installed at the end of the salt tank 803 near the resin tank 5. The end of the salt suction pipe 7 away from the salt tank 803 is inserted into the interior of the resin tank 5.

[0037] The effect achieved by the entire second embodiment is as follows: Hard water flows into the resin tank 5 containing ion exchange resin through the inlet pipe 3. Sodium ions on the resin exchange with calcium and magnesium ions in the water. Calcium and magnesium ions are adsorbed by the resin, thereby reducing the hardness of the outflowing water and completing the softening process. The softened water is discharged through the outlet pipe 1. When the sodium ions on the resin inside the resin tank 5 are exhausted, the regeneration program needs to be started. At this time, brine from the salt tank 803 is injected into the resin tank 5 through the brine suction pipe 7. The concentration difference of sodium ions is used to replace the calcium and magnesium ions adsorbed on the resin and discharge them with the waste liquid through the drain pipe 4, so that the resin can restore its softening ability and be put back into use.

[0038] Working principle: Hard water flows into the resin tank 5 containing ion exchange resin through the inlet pipe 3. Sodium ions on the resin exchange with calcium and magnesium ions in the water. The calcium and magnesium ions are adsorbed by the resin, thereby reducing the hardness of the outflowing water and completing the softening process. The softened water is discharged through the outlet pipe 1.

[0039] Secondly, when the sodium ions on the resin inside the resin tank 5 are exhausted, the regeneration process needs to be started. At this time, the brine inside the salt tank 803 is injected into the resin tank 5 through the salt suction pipe 7. The calcium and magnesium ions adsorbed on the resin are replaced by the sodium ion concentration difference and discharged with the waste liquid through the drain pipe 4, so that the resin can restore its softening ability and be put back into use.

[0040] Finally, the salt level inside the salt tank 803 can be directly monitored through the observation window 801. When the salt level is observed to be lower than the set threshold, the drive motor 806 is started by the control switch. The power of the drive motor 806 is transmitted to the feeding plate 812 through the transmission shaft 810, causing it to rotate. The surface of the feeding plate 812 is evenly distributed with discharge troughs 811. During the rotation, the salt blocks in the discharge troughs 811 located below the feeding plate 812 fall smoothly into the salt tank 803 under the action of gravity through the discharge pipe 809. At the same time, the salt blocks in the storage hopper 808 are automatically filled into the empty discharge troughs 811 above the feeding plate 812. After the discharge troughs 811 are full, as the feeding plate 812 continues to rotate, the newly filled salt blocks are transported to the discharge pipe 809 for discharge. This cycle is repeated to achieve automatic salt addition to the salt tank 803, minimizing the downtime of the water softener caused by manual salt addition and significantly improving the continuous working efficiency and operational stability of the device.
