TECHNICAL FIELD

[0002] Secondary water supply refers to the water that has been treated and purified further to meet the water quality requirements of specific uses after the primary treatment of raw water (usually tap water or groundwater), and then provided to users or consumers. After the primary treatment of raw water, it may still contain some trace amounts of suspended solids, dissolved substances, organic matter, microorganisms or harmful substances. Through depth purification, these residual pollutants can be further removed to ensure that the water supply meets the specific water quality standards to protect people's health and safety.
[0003] When secondary water supply is subjected to depth purification, there are various methods that can be used, among which the ion exchange resin method can efficiently remove cations and anions in water, including hardness ions, heavy metal ions and harmful substances, which helps to improve water quality and reduce the content of pollutants in water. However, when ion exchange resin is used for depth purification of secondary water supply, the ion exchange resin will gradually be saturated with adsorbed ions and impurities after long-term use, resulting in a decrease in its adsorption and exchange capacity. In order to restore the adsorption and exchange performance of the resin and prolong its service life, regeneration operation is required. The existing resin needs to stop water supply during regeneration operation, and in-situ regeneration during shutdown will cause the interruption of water purification for a period of time, which will affect the continuity of water supply and cause inconvenience to users.

DETAILED DESCRIPTION
[0034] The technical solution of the patent will be further described in detail below in combination with specific embodiments.
[0035] The embodiments of the patent will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the patent, and cannot be understood as a limitation of the patent.
[0036] Reference Figures 1-8 A secondary water supply deep purification system includes ion exchange resin purification tanks 1 and storage bins 2. The number of ion exchange resin purification tanks 1 is two, and both ion exchange resin purification tanks 1 are located inside the ion exchange resin purification tank 1. The inside of the storage bin 2 is provided with an exchange assembly.
[0037] The exchange assembly includes a motor 7 located at the inner bottom of the storage bin 2. The output end of the motor 7 is connected with a connecting rod 8 through two vertical bevel gears. The top end of the connecting rod 8 is fixedly connected with a storage plate 6. The end of the connecting rod 8 away from the storage plate 6 is rotatably connected with the storage bin 2. Both storage bins 2 are located at the top of the storage plate 6. Both ends of the two ion exchange resin purification tanks 1 are provided with connecting pipes 9. The inside of the ion exchange resin purification tank 1 is provided with a docking assembly.
[0038] Through the setting of the exchange assembly, downtime can be reduced. Specifically, the motor 7 rotates forward to drive the placement plate 6 to rotate. When the placement plate 6 rotates to exchange the positions of a group of unused ion exchange resin purification tanks 1 and saturated ion exchange resin purification tanks 1, the unused group of ion exchange resin purification tanks 1 can purify the secondary water supply, and the other group of saturated ion exchange resin purification tanks 1 can regenerate the saturated resin bed by pumping water from the other group of water supply pipes 16 through an external water pump. After regeneration, the regenerated wastewater is discharged through the water outlet pipe 17, avoiding interruption of water purification for a period of time and reducing the impact on the continuity of the water supply.
[0039] With reference to Figures 6-8 The docking assembly includes a driving part and a docking part. The driving part includes a rod body 10, which is rotationally connected to the placement bin 2. The rod body 10 is connected to the output shaft of the motor 7 through a synchronous belt transmission. The placement bin 2 is rotationally connected with a rotating rod 11 inside. The rod body 10 is connected to the rotating rod 11 through two bevel gears. The placement bin 2 is rotationally connected with two long rods 12 inside. One of the long rods 12 is connected to the rotating rod 11 through a synchronous belt transmission. The two long rods 12 are rotationally connected with a placement rod 14 between them. The placement rod 14 is connected to the long rods 12 through a synchronous belt transmission. The placement rod 14 is fixedly connected with a transmission gear 13 on the outer wall of the other long rod 12. The two transmission gears 13 are meshed. The docking part is provided in two groups. Each group of docking parts includes a water supply pipe 16 and a water outlet pipe 17. The water supply pipe 16 and the water outlet pipe 17 are located at both ends of the ion exchange resin purification tank 1. The facing ends of the water supply pipe 16 and the water outlet pipe 17 are provided with two groups of connecting rings 18. Each group of connecting rings 18 is provided with two connecting rings. A sliding joint 20 is provided between each group of connecting rings 18. The long rods 12 are fixedly connected with a pawl 15 at both ends. The pawl 15 is located directly below the corresponding connecting ring 18.
[0040] When the height sensor 21 detects that the height of the resin bed inside the ion exchange resin purification tank 1 changes, the resin is saturated, and the motor 7 is controlled to reverse by the controller 23. When the motor 7 reverses, the rod body 10 is rotated by the synchronous belt, the rotating rod 11 is rotated by the bevel gear, one of the long rods 12 is rotated, the placement rod 14 is rotated, and then the two long rods 12 are relatively rotated by the two transmission gears 13. When the two long rods 12 relatively rotate, the two pawls 15 are rotated, the two connecting rings 18 are relatively close to each other, the spring 19 is contracted, and the connecting ring 18 is separated from the connecting pipe 9. When the connecting ring 18 is separated from the connecting pipe 9 and retracted, the motor 7 is forward rotated to rotate the placement plate 6. When the placement plate 6 is rotated to exchange the positions of the two groups of ion exchange resin purification tanks 1, the motor 7 is reversed, the connecting ring 18 and the sliding joint 20 are retracted by the continuous rotation of the pawl 15, and the spring 19 is rebounded to connect the connecting ring 18 with the connecting pipe 9. Thus, the ion exchange resin purification tank 1 can be continuously purified and the other ion exchange resin purification tank 1 can be regenerated.
[0041] With reference to Figures 6-8 The bevel gear at the top end of the connecting rod 8 is internally provided with a one-way bearing, and two springs 19 are fixedly connected between each group of connecting rings 18. Each group of connecting rings 18 is connected with the corresponding connecting pipe 9.
[0042] The one-way bearing is provided, the placement plate 6 is rotated when the motor 7 is forward rotated, and the one-way bearing does not rotate the placement plate 6 when the motor 7 is reversed.
[0043] With reference to Figures 1-3 One side of the placement bin 2 is provided with a primary filter tank 3, one end of the primary filter tank 3 is provided with a water inlet pipe 5, and the inside of the primary filter tank 3 is provided with two filter screens 4. One end of the water inlet pipe 16 extends through the inside of the primary filter tank 3, and the top of the two ion exchange resin purification tanks 1 is provided with a sealing cover 22.
[0044] The primary filter tank 3 is provided to remove large particles and suspended solids in water, and plays a primary filtering role. The two filter screens 4 are provided to intercept large particles in water, effectively reducing the load pressure of subsequent purification. The sealing cover 22 is provided to facilitate the addition of ion exchange resin.
[0045] With reference to Figures 2-3The two ion exchange resin purification tanks 1 are provided with height sensors 21 on one side, and the ion exchange resin purification tanks 1 are provided with a controller 23 on the outside. The two water delivery pipes 16 and the water outlet pipe 17 are provided with electromagnetic valves inside. The motor 7, the height sensors 21 and the electromagnetic valves are electrically connected with the controller 23.
[0046] When the resin bed inside one set of ion exchange resin purification tanks 1 is saturated, the bed height usually increases. When the height sensor 21 detects the increase of the bed height, the motor 7 is started by the controller 23 to switch the positions of the two sets of ion exchange resin purification tanks 1.
[0047] Working principle: when in use, the secondary water is delivered into the primary filtration tank 3 through the water inlet pipe 5 by an external water pump (not shown in the figure), and the large particles and suspended matters in the water are removed by the two filter screens 4 to achieve primary filtration. The filtered water is delivered from one of the water delivery pipes 16 to the ion exchange resin purification tank 1 through the connecting pipe 9, and the secondary water is deeply purified by the resin bed. When one set of ion exchange resin purification tanks 1 is used for a period of time, the height sensor 21 detects the increase of the bed height. First, the external water pump is turned off, and the motor 7 is started by the controller 23. When the motor 7 is reversed, the rod body 10 is rotated by the synchronous belt, the rotating rod 11 is rotated by the bevel gear driven by the rod body 10, one of the long rods 12 is rotated by the rotating rod 11, the placing rod 14 is rotated by one of the long rods 12, and then the two long rods 12 are relatively rotated by the two transmission gears 13. When the two long rods 12 are relatively rotated, the two pawls 15 are rotated, and the two connecting rings 18 are moved towards each other. When the two connecting rings 18 are relatively rotated, the spring 19 is contracted. At this time, the connecting rings 18 are separated from the connecting pipe 9. When the connecting rings 18 are separated from the connecting pipe 9, the motor 7 is forward rotated to rotate the placing plate 6. When the placing plate 6 is rotated to exchange the positions of one set of unused ion exchange resin purification tanks 1 and the saturated ion exchange resin purification tanks 1, the motor 7 is reversed, the connecting ring 18 and the sliding joint 20 are moved back by the continuous rotation of the pawl 15. When the pawl 15 continuously rotates without contacting the connecting ring 18, the spring 19 is rebounded to connect one of the connecting rings 18 with the connecting pipe 9. Thus, the unused set of ion exchange resin purification tanks 1 can purify the secondary water, and the other set of saturated ion exchange resin purification tanks 1 can regenerate the saturated resin bed by pumping the reduced water from the other water delivery pipe 16 by the external water pump. After the regeneration is completed, the regenerated sewage is discharged through the water outlet pipe 17, and the next set of ion exchange resin purification tanks 1 is ready for replacement when saturated.
[0048] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
