The ion exchanger of the invention optimizes the sealing property, the maintainability and the installation operability of the ion exchanger.
1. Optimizing the sealing property:
in the ion exchanger of the present invention, since the whole purification effect is considered, the pool water entering the ion exchanger should sufficiently flow through the anion and cation resins of the upper and lower purification elements as shown in the flow direction of the pool water in fig. 2, and the connection combination part through which the pool water flows, etc. should be strictly sealed where a gap may be generated. Mainly involves three seals: the sealing of the water drawing device and the equipment cylinder, the sealing of the equipment cylinder and the base and the sealing of the upper purifying element. The invention optimizes the sealing performance of the ion exchanger:
1.1 sealing of Water-drawing devices to the cylinders of the Equipment
Referring to fig. 3, the present invention designs a sealing flange 2 as a component for connecting a water drawing device and an equipment cylinder, wherein a sealing flange step 21 is formed at the upper end of the sealing flange 2 for placing the water drawing device 1, and a water drawing sealing groove 11 is formed at the bottom end of the water drawing device 1 for placing a first sealing ring 91 to form a seal with a flat sliding platform step surface of the sealing flange 2.

Referring to fig. 4, in the structure in which the first sealing ring 91 is used for sealing, different gasket types, different sealing groove types, and different pressing forces produce different sealing performances. The invention was tested before design and the test results are shown in figure 4 as a graph of the relationship between the pressing force and the type of seal. 4 cases were tested separately:
(1) Sealing grooves are formed in the bottom end of the water drawing device and the sealing flange step, and O-shaped rings are adopted as sealing rings;
(2) The bottom end of the water drawing device and the sealing flange step are not provided with a sealing groove, and the sealing ring adopts a flat gasket;
(3) A sealing groove is formed in the bottom end of the water drawing device, no groove is formed in the step of the sealing flange, and an O-shaped ring is adopted as the sealing ring;
(4) The bottom end of the water drawing device is provided with a sealing groove, the step of the sealing flange is not provided with a groove, and the sealing ring adopts a flat gasket.
Through comparison of multiple groups of tests, the fact that the flat gasket has a good performance in the structure of the ion exchanger compared with an O-shaped ring is found, and in consideration of stability in combination with a slotting mode, a fourth sealing mode is adopted, the bottom end of the water drawing device 1 is provided with a water drawing sealing groove 11, a sealing flange step 21 is not slotted, and the first sealing ring 91 is a flat gasket.
1.2 sealing of Equipment cylinders with bases
Referring to fig. 5, the lower end of the equipment cylinder and the upper end of the base are both flange structures, and the two are matched. The contact surfaces of the base flange 61 and the lower barrel flange 32 are processed smoothly, so that the two flanges can generate a tightly attached sealing surface after being fixed by bolts and nuts to achieve the sealing effect.
The lower purifying element 5 and the base 6 are sealed by a base sealing ring 62 structure on the base flange 61, and can be sealed with the lower purifying element sealing groove 51 at the bottom of the lower purifying element 2, a third sealing ring 93 is placed in the same lower purifying element sealing groove 51 to ensure the sealing performance, the third sealing ring 93 is fixed in a mode of being adhered to the bottom of the lower purifying element sealing groove 51 by using industrial glue, the sealing ring is conveniently updated when the purifying element is replaced subsequently, and the third sealing ring 93 is preferably a flat gasket.

1.3 sealing of the upper cleaning element
Referring to fig. 6, the upper purifying element is sealed by a sealing ring 8, so that a sealed passage is formed between the upper purifying element 4 and the water drawing device 1, and it is ensured that the pond water drawn from the water drawing device 1 can directly enter the upper purifying element 4, the sealing ring 8 and the water drawing device 1 are welded and fixed into a whole, and the whole pond water only flows downwards as a complete environmental protection certificate. The place that meets with sealing ring 8 is upper cover plate 40 of last purification element 4, and the upper surface of upper cover plate 40 has processed the last purification element seal groove 41 that can place the sealing washer, and it is slightly bigger than second sealing washer 92 to need to guarantee to go up the width of purification element seal groove 41 simultaneously, and the notch edge of going up the purification element seal groove is provided with the installation that the guide chamfer makes things convenient for sealing ring 8. Because the seal and the seals between the upper water drawing device 1 and the sealing flange 2 are hard seals, the second sealing ring 92 at the sealing ring 8 should be a flat gasket made of a material with better elasticity, and the thickness of the gasket must be thicker, so that the sealing ring at the position can generate a larger deformation amount, and the two seals can meet the requirement of no leakage.
2. Maintainability optimization
Referring to fig. 7 and 8, in the ion exchanger of the present invention, the anion and cation resins are filled in the purification elements, the upper and lower purification elements are separate components, the upper and lower purification elements have hollow cavities 43, the upper cover plate 40 of each purification element has a cover plate through hole 42, and the hollow cavity 43 is located below the cover plate through hole 42, so as to be used as a passage for water flow during water filtration, and for lifting and replacing with a special tool. The upper cover plate of the upper purifying element and the upper cover plate of the lower purifying element are both provided with feed inlets, and inlet plugs 44 are arranged in the feed inlets.
When the water drawing device 1 is disassembled and replaced, the outer-diameter three-jaw lifting appliance is firstly used for lifting along the outer edge bulge of the flange at the top end of the water drawing device 1, and the water drawing device 1 is taken down. Then, the inner-diameter three-jaw lifting appliance 500 is used for lifting by hooking the inner edge of the cover plate through hole 42 of the upper cover plate 40 of the upper purifying element 4, and the inner-diameter three-jaw lifting appliance can be vertically taken out along the equipment cylinder 3; the lower purification element 5 is also removed in the same way.
