[0027] The ion exchanger disclosed by the utility model is described below in conjunction with the accompanying drawings. Figure 1 As shown, it includes a tank body 100, and the tank body 100 can be a known tank body 100 structure, which is not described here. A group of lifting ears are provided on the top of the tank body 100 to facilitate the lifting of the tank body 100. An ion exchange layer 200 is provided in the tank body 100, and the ion exchange layer 200 can be a known cation exchange resin, anion exchange resin, etc., which is specifically designed according to the sewage to be treated and is not limited here.

[0028] As attached Figure 1 , Attachment Figure 2 As shown, the upper part of the tank body 100 is provided with a first liquid inlet 110, and an upper water distribution plate 300 is horizontally arranged in the tank body 100, which is located above the ion exchange layer 200 and below the first liquid inlet. The upper water distribution plate 300 can be fixed on the upper fixing rod 400 on the inner wall of the tank body 100 and keep a distance from the ion exchange layer 200. Of course, the upper water distribution plate 300 can also be fixed by welding a bracket that divides the circumference evenly at the inner wall of the tank body 100. The upper water distribution plate 300 is provided with a group of upper water distribution holes 310, and the layout form of the upper water distribution holes 310 can be designed as needed.

[0029] As attached Figure 1As shown, a second liquid inlet 120 is provided at the lower portion of the tank body 100, and a lower water distribution plate 500 located below the ion exchange layer 200 is provided in the tank body 100. The fixing method of the lower water distribution plate 500 can refer to the installation method of the upper water distribution plate 300, which is not limited here. A group of lower water distribution holes are provided on the lower water distribution plate 500, which can deliver water from the bottom of the ion exchange layer 200 to the ion exchange layer. The lower water distribution plate 500 is the same as the upper water distribution plate, which is not repeated here.

[0030] In order to prevent the inflow of water from impacting the water flow at the ion exchange layer 200 and to prevent the ion exchange layer 200 from overflowing, as shown in the attached Figure 1 As shown, the upper water distribution hole 310 is provided with an upper water cap 320, and the upper water cap 320 can be a known snap-on water cap. Similarly, the lower water distribution hole 510 is provided with a lower water cap 700, in order to facilitate assembly, as shown in the attached Figure 3 As shown, the lower water cap 700 includes a hollow tube 710, the outer wall of the hollow tube 710 is formed with an external thread, the two ends of the hollow tube 710 are screwed with a first filter cap 720 and a second filter cap 730, and the hollow tube 710 is also provided with a first sealing ring 740 and a second sealing ring 750 located between the two filter caps. During assembly, the first filter cap 720 can be screwed with the hollow tube 710, and the first sealing ring 740 can be installed, and then the hollow tube 710 can be inserted into the lower water distribution hole 510 and the first filter cap 720 and the first sealing ring 740 on the hollow tube 710 are located on one side of the lower water distribution plate 500, and the second sealing ring 750 is installed on the part of the hollow tube 710 located on the other side of the lower water distribution plate 500 and the second filter cap is screwed. Thus, the fixing of the hollow tube 710 and the lower water distribution plate 500 is achieved by the first filter cap and the second filter cap.

[0031] As attached Figure 1 , Attachment Figure 4 , Attachment Figure 5 As shown, a drain pipe 600 is also provided on the tank body 100, part of which is located in the ion exchange layer 200, and one end of which extends from the inside of the tank body 100 to the outside of the tank body 100, and a liquid collection hole 641 for allowing liquid to enter the drain pipe 600 is formed on the part of the drain pipe 600 located in the ion exchange layer 200.

[0032] The drain pipe 600 is located in the middle of the ion exchange layer 200. The drain pipe 600 includes a cross-connected collecting pipe 610 and a liquid outlet pipe 620. In order to ensure the stable installation of the drain pipe 600, the two ends of the collecting pipe 610 are respectively provided with connecting pieces 630 located at the bottom thereof. The tank body 100 is provided with mounting frames 130 corresponding to the connecting pieces 630 at the two ends of the collecting pipe 610. The connecting pieces 630 are screwed on the top of the mounting frames 130. At the same time, the liquid outlet pipe 620 extends from the tank body 100 to the outside of the tank body 100, so that the side wall of the tank body 100 can support the liquid outlet pipe 620. The two mounting frames 130 can support the two ends of the collecting pipe 610. The three-point support method can provide better support and stability for the drain pipe 600.

[0033] In order to match the increased water intake, the liquid collecting pipe 610 and / or the liquid outlet pipe 620 are connected with a liquid inlet pipe 640, and a liquid collecting hole 641 is formed on the liquid inlet pipe 640. The aperture of the liquid collecting hole satisfies that the ion exchange layer will not enter the liquid collecting pipe. Preferably, the liquid collecting pipe 610 and the liquid outlet pipe 620 are perpendicular and they are distributed in a T shape. The liquid inlet pipe 640 is parallel to the liquid outlet pipe 620 and they are symmetrically distributed on both sides of the liquid outlet pipe 620, so that the length of the liquid inlet pipe 640 on one side of the liquid outlet pipe 620 is gradually shortened from the center of the tank body 100 to the side wall of the tank body 100. At the same time, coaxial liquid inlet pipes 640 are respectively arranged on both sides of the liquid collecting pipe 610. The specific number and length of the liquid inlet pipe 640 can be designed as needed and are not limited here.

[0034] Further, in order to reduce the backflow of the water outflow from the liquid outlet pipe 620 as much as possible, as shown in the attached Figure 5 As shown, the liquid outlet pipe 620 is located below the liquid collecting pipe 610, that is, a vertical pipe 650 located in the middle is provided at the bottom of the water collecting pipe, and the vertical pipe 650 is connected to the liquid storage pipe.

[0035] When in use, sewage is transported to the tank body through the first liquid inlet and the second liquid inlet at the same time, and the sewage is transported to the ion exchange layer through the upper water cap and the lower water cap for ion exchange, and the liquid passing through the ion exchange layer enters the liquid storage pipe through the liquid inlet pipe and is discharged.

[0036] Since the installation scene of the tank body 100 is different and it is likely that the tank body 100 cannot be guaranteed to be flat, the following Figure 1As shown, a support foot 800 is provided at the bottom of the tank body 100, and a leveler 900 is provided at the support foot 800. The number and position of the leveler 900 can be set as needed, and are not limited here. The leveler 900 includes a bottom plate 910, and a stud 920 is vertically provided on the bottom plate 910. An adjusting nut 930 and a locking nut 940 are screwed on the stud 920. The stud 920 is passed through the connecting plate 810 on the support foot 800 and is fixed to the connecting plate 810 by the adjusting nut 930 and the locking nut 940. The adjusting nut 930 is located below the connecting plate 810, and the fastening nut is located below the connecting plate 810. The height of the connecting plate 810 can be adjusted by adjusting the height of the adjusting nut 930 and the fastening nut.

[0037] Of course, the tank body is also provided with other structures of known ion exchangers, such as an exhaust port, a drain port, a backwash port, etc. These structures are not innovations of the present application and will not be described in detail here.

[0038] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
