Description

Technical Field

[0001] The utility model relates to the technical field of softened water, and more specifically to a water softening device. Background Art

[0002] Water softening is a process of making water softer by removing hard ions in water and reducing the content of calcium and magnesium ions in water. Calcium and magnesium ions in water will cause an increase in water hardness, and hard water will not only have an adverse effect on water quality, but also affect the service life of household appliances;

[0003] Currently, when softening water, ion exchange and reverse osmosis are usually used. Ion exchange is to adsorb calcium and magnesium ions in water through anion exchange resin in a water softening device. The calcium and magnesium ions in water will exchange with sodium ions on the resin surface, so that the calcium and magnesium ions in water are removed or reduced, and the sodium ions on the exchange resin are released, playing a role in softening water. However, when softening water, if the water is not filtered, impurities in the water are likely to adhere to the surface of the ion exchange resin. In the long run, it will affect the softening effect of the ion exchange resin on water. And when the ion exchange resin is used for a long time, the adsorption of calcium and magnesium ions in water will reach a saturated state. If the softening exchange function is not restored in time, it will affect the softening effect of the ion exchange resin on water, which needs to be improved. Summary of the Utility Model

[0028] Embodiment 3:

[0029] As Figures 1 - 4 shown in the figure, the resin regeneration and recovery mechanism 6 includes two brine tanks 61. The two brine tanks 61 are fixedly connected below both sides of the softening tank 1. Brine is provided inside the brine tanks 61.

At this time, the ion exchange resin 42 is used to remove calcium and magnesium ions in the water, and release sodium ions, making the water soft. After softening, the water is discharged through the drain hole 43 and the drain pipe 5;

[0032] When the upper filter screen 25 and the lower filter screen 26 need to be cleaned after long-term use, the staff can screw off the tank cover 21.

After cleaning, place the upper filter screen 25, the connecting rod 27 and the lower filter screen 26 inside the support frame 23, and make the two sides inside the upper filter screen 25 and the lower filter screen 26 sleeve on the outer walls of the two limit pins 28. Then screw the nut 29 onto the top of the limit pin 28, and make the bottom of the nut 29 lap on the top of the upper filter screen 25, so that the upper filter screen 25 and the lower filter screen 26 can be fixedly installed inside the support frame 23. Then screw the tank cover 21 onto the inside of the softening tank 1, and the tank cover 21 drives the support frame 23 to move into the inside of the softening tank 1 through the support rod 22, and then the upper filter screen 25 and the lower filter screen 26 can be used continuously;

[0033] When the ion exchange resin 42 adsorbs calcium and magnesium ions in the water to reach the saturation state, use the air compressor 62 to press air into the brine tank 61, strongly press the brine into the inside of the conduit 64, and spray it out through the nozzle 65. At the same time, the brine enters the softening cover 4 through the water inlet hole 41 to wash the ion exchange resin 42, displace the hardness ions on the resin, and restore its softening and exchange function. Then the brine is discharged into the bottom of the inner cavity of the softening tank 1 through the drain hole 43 and discharged from the drain pipe 5.
