[0030] 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.

[0031] The following describes an embodiment of this utility model based on its overall structure.

[0032] like Figures 1 to 5 As shown, this utility model provides a high-efficiency ion exchange resin tank, including a tank assembly 1. The tank assembly 1 includes a shell 101. A stirring assembly 2 is provided inside the shell 101. The stirring assembly 2 includes a mounting bracket 201 fixedly disposed on the inner wall of the shell 101. A first motor 202 is fixedly disposed inside the mounting bracket 201. A main half gear 203 is fixedly disposed at the end of the main shaft of the first motor 202. A bottom half gear 204 is meshed at the bottom of the main half gear 203. A connecting platform 205 is fixedly disposed at the bottom of the bottom half gear 204. A fixing frame 206 is fixedly disposed at the bottom of the connecting platform 205. Four stirring rods 207 are axially fixed at the bottom of the fixing frame 206 to expand the agitation range, avoid resin caking, flow deviation, and channeling, improve ion exchange contact efficiency, and make the exchange more complete.

[0033] In a further embodiment, a second motor 208 is fixedly installed inside the connecting platform 205. The end of the main shaft of the second motor 208 passes through the fixed frame 206 and is fixedly provided with a screw 209. A pressure plate 210 is spirally sleeved on the outside of the screw 209. A slide rod 211 is symmetrically fixed at the bottom of the fixed frame 206. The slide rod 211 is slidably connected to the pressure plate 210. A connecting plate 212 is fixedly provided at the bottom of the slide rod 211, which can adjust the density of the resin layer to adapt to the operation, backwashing, and regeneration conditions. When moving downwards, it can push and squeeze the resin to facilitate the resin discharge from the bottom outlet.

[0034] The pressure plate 210 has several water passage holes inside to ensure normal water flow and not block the water path. The outer wall of the pressure plate 210 is attached to the inner wall of the outer shell 101, which can scrape off the resin adhering to the wall surface and prevent wall flow and scaling.

[0035] The bottom inner side of the housing 101 is provided with a filter assembly 3, which includes a filter plate 31 to intercept broken resin and protect the water outlet and pipeline. The bottom of the filter plate 31 is symmetrically fixed with a support frame 32, which is slidably connected to the housing 101 for easy disassembly and replacement.

[0036] Water distribution plates 102 are fixed to the upper and lower sides of the outer casing 101 by bolts. Several installation ports 103 are opened inside the water distribution plates 102. Water caps 104 are fixed inside the installation ports 103, so that the water flow is evenly distributed and the flow deviation is reduced.

[0037] The top of the outer shell 101 is fixed with a top cover 105 by bolts. The top of the top cover 105 is fixed with an exhaust port 106, a top water inlet 107 and a spare port 108. The bottom of the outer shell 101 is fixed with a bottom cover 109 by bolts. The bottom of the bottom cover 109 is fixed with an outlet 110 and a bottom water inlet 111. The top water inlet 107 and the bottom water inlet 111 are adapted to co-current and counter-current regeneration processes. The exhaust port 106 promptly discharges air from the tank to prevent air resistance from affecting water flow and exchange. The spare port 108 is reserved for expansion, chemical dosing and monitoring interfaces, providing strong expandability.

[0038] A resin inlet 112 is fixedly provided on the top left side of the outer casing 101, and a resin outlet 113 is fixedly provided on the bottom right side of the outer casing 101. Valves 114 are fixedly provided inside both the resin inlet 112 and the resin outlet 113, which facilitates the filling, replacement and discharge of resin without removing the top cover 105. Sight glass openings 115 are symmetrically fixed on the front side of the outer casing 101, which can directly observe the resin level, stirring status and water flow in the tank.

[0039] The motor is existing technology and will not be described in detail. This invention also includes a power supply, controller, and switch, which are not the main technical aspects of this invention and will not be described in detail either. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model should be selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0040] The working principle and process of a high-efficiency ion exchange resin tank:

[0041] First, open valve 114 at resin inlet 112 and fill ion exchange resin into the shell 101 through resin inlet 112. During the filling process, the resin filling height can be observed through the sight glass 115 symmetrically arranged on the front side. After the preset resin bed height is reached, close valve 114 at resin inlet 112 to complete the resin filling. At this time, pressure plate 210 is above the resin bed to avoid squeezing the resin and affecting the subsequent ion exchange effect.

[0042] According to the treatment process requirements, the water to be treated is introduced through the top inlet 107. The water is evenly distributed through the water caps 104 on the corresponding side water distribution plate 102, and slowly permeates into the resin bed. At the same time, the first motor 202 is started, driving the main half gear 203 to rotate. The main half gear 203 meshes with the bottom half gear 204, driving the connecting platform 205, the fixed frame 206, and the four stirring rods 207 at the bottom to rotate synchronously, uniformly disturbing the resin bed, preventing resin caking and flow deviation, and ensuring that the resin and the water to be treated are in full contact, efficiently completing the ionization process. In the ion exchange reaction, if it is necessary to adjust the density of the resin bed to optimize the exchange efficiency, the second motor 208 can be started. The second motor 208 drives the screw 209 to rotate, which drives the pressure plate 210 to rise and fall smoothly along the slide rod 211, compacting the resin bed to a suitable density. The water passage holes on the pressure plate 210 ensure that the water can pass through normally without blocking the water path. Its outer wall is in contact with the inner wall of the outer shell 101, which can scrape off the resin adhering to the tank wall and prevent wall flow. After the water that has completed ion exchange is intercepted and broken by the bottom filter plate 31, it is discharged through the outlet 110 on the bottom cover 109. The filter plate 31 is open to the water. The support frame 32 is slidably connected to the outer shell 101, which can effectively intercept broken resin and prevent it from being lost with the outflowing water and clogging the pipeline. During operation, the air generated inside the tank is discharged in time through the exhaust port 106 on the top cover 105 to prevent air resistance from affecting water flow and ion exchange effect. When the resin adsorption capacity decreases and regeneration is required, the water inlet direction is switched, and backwash water is introduced through the bottom water inlet 111. After the backwash water is evenly distributed by the bottom water distribution plate 102, it washes the resin bed upward. At the same time, the first motor 202 is started to drive the stirring rod 207 to rotate, which helps to loosen the resin bed. The impurities adsorbed on the resin surface are washed off. During the backwashing process, the backwashing situation can be observed through the sight glass 115. After the backwashing wastewater is filtered by the top water distribution plate 102, it can be discharged through the top water inlet 107 or the spare port 108. After the backwashing is completed, the regenerating liquid is introduced through the top water inlet 107. The regenerating liquid is evenly distributed through the top water distribution plate 102 and penetrates into the resin bed to regenerate with the failed resin, restoring the resin's ion exchange capacity. During the regeneration process, the density of the resin bed can be adjusted by raising and lowering the pressure plate 210 to ensure that the regenerating liquid and the resin are in full contact, thereby improving the regeneration effect.

[0043] When the resin reaches the end of its service life and needs to be replaced, close the relevant interfaces, open the valve 114 at the resin outlet 113, start the second motor 208, drive the screw 209 to rotate, and drive the pressure plate 210 to move slowly downward along the slide bar 211. Since the outer wall of the pressure plate 210 is in contact with the inner wall of the outer shell 101, the resin in the tank can be pushed to the bottom during the downward movement, while scraping off the resin remaining on the tank wall and pushing it to the resin outlet 113 for discharge. During the process, the resin discharge can be observed through the sight glass 115. If necessary, a small amount of clean water can be introduced through the bottom water inlet 111 to assist the resin discharge and ensure that the resin is discharged without residue.
