DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0022] Combination Figure 1-Figure 2 A connecting pipe for an EDI membrane stack includes a water inlet pipe 2 arranged on one side of the EDI membrane stack body 1, one end of the water inlet pipe 2 is movably connected to a connecting water pipe 8, the outer surface of the connecting water pipe 8 is fixedly connected to a fixed pipe 3, and the end of the connecting water pipe 8 away from the fixed pipe 3 is provided with a filtering component 5 for filtering.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Embodiment 1:

[0025] See also Figure 2-Figure 5 The filter assembly 5 includes a filter box 51 fixedly passing through one end of the connecting water pipe 8, a connecting block 52 movably arranged inside the filter box 51, a pull block 53 fixedly connected to the top of the connecting block 52, and a total filter layer 54 movably arranged inside the connecting block 52. A chute 511 is provided on the upper surface of the filter box 51, and the connecting block 52 is slidably connected to the chute 511. A through hole 521 is provided on one side of the connecting block 52. The total filter layer 54 is movably arranged inside the through hole 521. The diameter of the through hole 521 is equal to the outer diameter of the connecting water pipe 8. The filter box 51 is away from one end of the connecting water pipe 8. A water inlet pipe 4 is fixedly passed through, and the diameter of the water inlet pipe 4 is equal to the diameter of the connecting water pipe 8. Through the sliding connection between the connecting block 52 and the slide groove 511, the pulling block 53 is pulled to facilitate pulling the connecting block 52 out from the inside of the slide groove 511, so that the total filter layer 54 can be easily inspected, replaced or cleaned, which greatly improves the maintenance efficiency. The total filter layer 54 is arranged inside the through port 521, and the diameter of the through port 521 matches the outer diameter of the connecting water pipe 8, which ensures the uniform distribution of water flow, improves the filtering effect, and effectively blocks particulate matter and impurities from entering the EDI membrane stack body 1.

[0026] The total filter layer 54 includes a first filter layer 541, a second filter layer 542 and a third filter layer 543. The first filter layer 541 is a PP cotton layer, the second filter layer 542 is an activated carbon layer, and the third filter layer 543 is a sodium ion resin layer. Each filter layer removes different types of impurities in a targeted manner, forming a filtration process from coarse to fine. The PP cotton layer first intercepts large particles of suspended solids as a primary filtration, and the activated carbon layer facilitates the effective adsorption of organic matter and some chlorides in the water. The sodium ion resin layer further removes hardness ions in the water.

[0027] A first sealing gasket 6 is fixedly connected to the connection between the pull block 53 and the slide groove 511 . The addition of the first sealing gasket 6 can effectively prevent water from leaking at the connection between the pull block 53 and the slide groove 511 .

[0028] A spring 31 is fixedly connected to the inner surface of the fixed tube 3, a clamping pad 7 is fixedly connected to one end of the spring 31, a friction pad 71 is fixedly connected to the side of the clamping pad 7 away from the spring 31, and the friction pad 71 is in contact with the outer surface of the water inlet pipe 2. The elastic force of the spring 31 can be easily adjusted by the expansion and contraction of the spring 31 to maintain close contact with the water inlet pipe 2. The clamping pad 7 increases the friction between the contact surfaces, thereby further enhancing the fixing effect.

[0029] A limiting groove 81 is provided at one end of the connecting water pipe 8 close to the water inlet pipe 2, and the water inlet pipe 2 is engaged with the limiting groove 81. The engagement connection between the limiting groove 81 and the water inlet pipe 2 ensures precise position alignment between the two components, avoids misalignment during installation, and ensures smooth water flow.

[0030] A second sealing gasket 811 is fixedly connected inside the limiting groove 81. The second sealing gasket 811 is located inside the limiting groove 81. When the water inlet pipe 2 is engaged with the limiting groove 81, the second sealing gasket 811 can effectively fill the small gap between the two to form a tight seal.

[0031] When in use, the connecting water pipe 8 is connected to the water inlet pipe 2. At this time, the limit groove 81 is engaged with the water inlet pipe 2, and the second sealing gasket 811 is convenient for effectively filling the small gap between the two to form a tight seal. The elastic force of the spring 31 can be adjusted by the expansion and contraction of the spring 31 to fix the water inlet pipe 2. After the water enters the opening 521 from the water inlet pipe 4, it is filtered by the total filter layer 54. The PP cotton layer first intercepts large particles of suspended solids as a primary filtration, and the activated carbon layer is convenient for effectively adsorbing organic matter and some chlorides in the water. The sodium ion resin layer further removes hardness ions in the water. The filtered water flows into the water inlet pipe 2 through the connecting water pipe 8, and finally flows into the EDI membrane stack body 1. When the total filter layer 54 needs to be replaced, the connecting block 52 is pulled out from the slide groove 511 by pulling the pull block 53, so that the total filter layer 54 can be easily inspected, replaced or cleaned, which greatly improves the maintenance efficiency.
