Description

Technical Field

[0001] The invention relates to the technical field of softened water treatment, in particular to softened water treatment equipment and a treatment method. Background Art

[0002] A common softening water treatment equipment is the ion exchange resin softener. The ion exchange resin softener uses the principle of ion exchange to exchange the hard water ions (mainly calcium ions and magnesium ions) in the water with the sodium ions in the resin, thereby softening the water.

[0003] The existing patent (publication number: CN117049653A) discloses an ion exchange softening water treatment equipment, including an exchange tower No. 1, an exchange tower No. 2, a regeneration tower, a cleaning tower, and a salt dissolving box. The top of the exchange tower No. 1 is connected to the bottom of the exchange tower No. 2 through a primary softening water delivery pipe, and a raw water inlet pipe is provided at the bottom of the exchange tower No. 1. The exchange tower No. 1 and the exchange tower No. 2 are respectively connected to the top of the regeneration tower through a saturated resin delivery pipe; a soft water outlet is provided at the top of the exchange tower No. 2; the bottom of the regeneration tower is connected to the top of the cleaning tower through a regenerated resin delivery pipe; the bottom of the cleaning tower is respectively connected to the top of the exchange tower No. 1 and the top of the exchange tower No. 2 through a new resin delivery pipe. The above-mentioned ion exchange softening water treatment equipment realizes secondary sodium ion exchange through two exchange towers, and utilizes the exchange capacity of the resin to adsorb calcium and magnesium ions in the raw water, thereby reducing the hardness of the raw water and making the raw water soft water. However, a large amount of debris will be generated during the filtration process. If it is not cleaned in time, it will lead to poor long-term filtration effect and affect the purity of softened water. At the same time, the ion exchange resin will gradually become saturated over time, that is, too many hard water ions are adsorbed in the resin, resulting in a decrease in the softening effect.

[0041] A method for treating softened water comprises the following steps:

[0042] S1. First, release the raw water through the raw water outlet pipe 2 and enter the interior of the filter box body 1 through the water inlet 3. The filter screen 51 on the surface of the water inlet 3 first filters out some impurities. Then, after the raw water is released for a period of time, start the dual-axis motor 71. The driving shaft on one side of the dual-axis motor 71 rotates, driving the threaded rod 72 to rotate. The rotation of the threaded rod 72 drives the threaded sleeve 73 on the surface to move. The side of the threaded sleeve 73 is fixedly connected with a connecting plate 74 which is limited by the telescopic rod 75 and slides toward the filter screen 51. When the connecting plate 74 slides, it drives the extrusion rod 78 fixedly connected to the side to move and squeeze the triangular plate 712. When the triangular plate 712 is squeezed, it drives the movable telescopic rod 711 to move upward. When the movable telescopic rod 711 moves upward, the filter screen 51 hinged on the surface of the water inlet 3 is lifted up through the universal shaft 713.

[0043] S2. When the filter screen 51 is lifted up, the connecting rod 61 movably connected to the side pushes the upper disc 63, so that the rotating rod 62 rotates through the disc 63. When the rotating rod 62 rotates, the ball valve 64 is driven to rotate, and the raw water outlet pipe 2 is closed to stop the outflow of raw water.

[0044] S3. When the output shaft at one end of the dual-axis motor 71 rotates, it is connected to the rotating rod 76 through the transmission belt 77. When the rotating rod 76 rotates, it drives the bevel gear 1 79 to rotate. The bevel gear 1 79 drives the meshing bevel gear 2 710 to rotate. The bevel gear 2 710 drives the connecting rod 58 fixedly connected at the upper end to rotate. The connecting rod 58 drives the spring rod 57 fixedly connected on the other side to rotate. The spring rod 57 has a telescopic function. At the same time, when the spring rod 57 rotates, it will drive the sliding rod 54 to reciprocate inside the sliding groove 53. When the sliding rod 54 slides back and forth, it will drive the scraper 55 fixed on the other side to scrape back and forth on the surface of the filter 51.

[0045] S4. When the output shaft at the other end of the dual-axis motor 71 rotates, the gear 81 is driven to rotate. When the gear 81 rotates, the side reduction gear 82 is driven to rotate. When the reduction gear 82 rotates, the double ring 83 is driven to rotate. When the double ring 83 rotates, the push rod 84 fixed to the side is driven to rotate. When the multiple push rods 84 rotate, they will repeatedly squeeze the spring telescopic rod 95 fixed at the lower end of the C-shaped block 94. When the spring telescopic rod 95 is squeezed, it will repeatedly squeeze the air pressure valve 98, and repeatedly inflate the sodium ion salt water tank 91. When the double ring 83 rotates to the inclined surface, the C-shaped block 94 will slide to the ring behind the double ring 83 through the inclined surface. At the same time, the C-shaped block 94 also slides through the telescopic rod 93. When the C-shaped block 94 slides, it will pull the circular plug 96 fixed to the side to slide and open the water outlet 97.
