[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5A double-layer corrosion-resistant ion exchange column includes an ion exchange column shell structure 1, which is composed of a first shell 101, a second shell 102, a third shell 103, and a fourth shell 104. The first shell 101, second shell 102, third shell 103, and fourth shell 104 are fixedly connected by flanges. A resin feed pipe 105 is welded to the top of one side of the second shell 102 and the third shell 103, and a resin discharge pipe 106 is welded to the bottom of one side of the second shell 102 and the third shell 103. Valves are provided on the resin feed pipe 105 and the resin discharge pipe 106. A material discharge pipe 107 is welded to the top of the first housing 101, and a material inlet pipe 108 is welded to the bottom of the fourth housing 104. Resin is filled into the second housing 102 and the third housing 103 through the resin inlet pipe 105 to form a resin bed. Then, water is pumped into the fourth housing 104 through the material inlet pipe 108 below. The water then flows upward and passes through the resin bed in the third housing 103 and the resin bed in the second housing 102 in sequence. When passing through, the ions in the water will exchange with the ions on the resin, so that the sodium ions on the resin will exchange with the calcium and magnesium ions in the water, thereby reducing the hardness of the water.

[0025] The first housing 101, the second housing 102, the third housing 103, and the fourth housing 104 are all composed of an inner anti-corrosion layer 1022, a metal base layer 1021, and an outer anti-corrosion layer 1023. The inner anti-corrosion layer 1022 is a polytetrafluoroethylene layer, and the outer anti-corrosion layer 1023 is a glass flake coating, thereby providing internal and external protection for the first housing 101, the second housing 102, the third housing 103, and the fourth housing 104. The inner anti-corrosion layer 1022, the metal base layer 1021, and the outer anti-corrosion layer 1023 are arranged from the inside to the outside. The first housing 101, the second housing 102, and the third housing 103 are all equipped with filter components 2.

[0026] The filter assembly 2 includes filter plates 201. Multiple filter plates 201 are fixed in the first housing 101, the second housing 102 and the third housing 103 by bolts. Multiple filter holes 202 are provided on the filter plates 201. Filter covers 203 are snapped into the top and bottom of the filter holes 202. The three-layer filter assembly 2 performs multiple filtration treatments on the water. A support base 3 is welded to the outer circumference of the fourth housing 104. A support frame 4 is welded to the bottom of the support base 3 to support the outer shell structure 1 of the ion exchange column. Connecting rings 5 ​​are welded between the multiple inner walls of the support frame 4.

[0027] Multiple connecting lugs 6 are welded to the top outer wall of the first housing 101, the circumferential outer wall of the second housing 102, the circumferential outer wall of the third housing 103, and the bottom outer wall of the fourth housing 104. Steel wire ropes are fastened to the connecting lugs 6 so that the first housing 101, the second housing 102, the third housing 103, and the fourth housing 104 can be hoisted using hoisting equipment. Multiple fixing ribs 7 are welded to the top outer wall of the first housing 101, the circumferential outer wall of the second housing 102, the circumferential outer wall of the third housing 103, and the bottom outer wall of the fourth housing 104. One side of the fixing ribs 7 is fixedly connected to the connecting lugs 6, thereby strengthening the connection between the connecting lugs 6 and the first housing 101, the second housing 102, the third housing 103, and the fourth housing 104.

[0028] The tops of the second shell 102, the third shell 103, and the fourth shell 104 are all welded with guide cylinders 8. The bottom ends of the first shell 101, the second shell 102, and the third shell 103 are respectively inserted into the guide cylinders 8. The top ends of the guide cylinders 8 are welded with lower flanges 9. The outer circumferential walls of the first shell 101, the second shell 102, and the third shell 103 are all welded with upper flanges 10. The lower flanges 9 and the upper flanges 10 are fixed together by bolts. The bottom ends of the first shell 101, the second shell 102, and the third shell 103 are respectively inserted into multiple guide cylinders 8. Then, the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104 are assembled vertically. Then, bolts are passed through the lower flanges 9 and the upper flanges 10 to fix the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104, thereby completing the assembly of the ion exchange column shell structure 1.

[0029] The inner circumferential walls of the second housing 102, the third housing 103, and the fourth housing 104 are fitted with lower sealing rings 12, and the bottoms of the first housing 101, the second housing 102, and the third housing 103 are fitted with upper sealing rings 11. The upper sealing rings 11 contact the lower sealing rings 12, thereby sealing the first housing 101, the second housing 102, the third housing 103, and the fourth housing 104.

[0030] The working principle of this embodiment is as follows: In use, firstly, the wire rope is tied to the connecting lug 6. Then, the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104 are hoisted using hoisting equipment, so that the bottom ends of the first shell 101, the second shell 102, and the third shell 103 are respectively inserted into multiple guide cylinders 8. Then, the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104 are assembled vertically. Then, bolts are passed through the lower flange 9 and the upper flange 10 to fix the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104. The upper sealing ring 11 and the lower sealing ring 12 are in contact to seal the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104, thereby completing the assembly of the ion exchange column shell structure 1.

[0031] The inner anti-corrosion layer 1022 is a polytetrafluoroethylene layer that provides internal protection for the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104, and has the property of resisting chemical media. Then, the outer anti-corrosion layer 1023 is a glass flake coating that provides external protection for the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104, thereby giving the first shell 101, the second shell 102, the third shell 103, and the fourth shell 104 extremely strong impermeability, as well as temperature resistance, wear resistance, and impact resistance.

[0032] Then, resin is fed into the second housing 102 and the third housing 103 through the resin feed pipe 105 to form a resin bed. Next, water is pumped into the fourth housing 104 through the material feed pipe 108 below. Then, the water flows upward and passes through the resin bed in the third housing 103 and the resin bed in the second housing 102 in sequence. When passing through, the ions in the water will exchange with the ions on the resin, so that the sodium ions on the resin will exchange with the calcium and magnesium ions in the water, thereby reducing the hardness of the water. At the same time, the water is filtered multiple times by the three-layer filter assembly 2. Finally, the treated water is discharged from the material discharge pipe 107.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
