Description

Technical Field

[0001] This utility model relates to the field of defluoridation equipment technology, specifically a high-efficiency defluoridation device for drinking water. Background Technology

[0002] In the process of purifying drinking water, it is necessary not only to filter out impurities in the water, but also to reduce the fluoride content.

[0003] A prior art device for defluoridating drinking water, disclosed in CN220245658U, includes a defluoridation tank and a tank cover. The tank has an inlet pipe on its lower side wall and an outlet pipe at its bottom. The tank includes an outer shell and an inner liner. The top of the inner liner has an opening. A cavity exists between the outer shell and the inner liner. A spiral guide plate is fitted inside the cavity, dividing it into multiple first filling zones. A mesh is installed inside the inner liner, dividing it into an interception zone and a second filling zone. Multiple through holes are opened on the bottom wall of the inner liner, and a third filling zone is located below the inner liner.

[0004] When the above equipment is in use, some of the filtered impurities will adhere to the inner wall of the defluorination tank and the crushed stone, making them difficult to clean. Utility Model Content

[0020] 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.

[0021] like Figure 1-2 As shown, the drinking water high-efficiency defluoridation device of this embodiment includes a shell 1, a support leg 2, a sewage pipe 3, a clean water pipe 4, and a drain pipe 5. An inner cylinder 6 is fixedly installed in the middle of the inner cavity of the shell 1. There is a gap between the top of the inner cylinder 6 and the shell 1. A hydraulic cylinder 7 is fixedly installed at the top of the shell 1. A first filter plate 8 is fixedly installed in the inner cavity of the inner cylinder 6. A lifting plate 9 is installed below the first filter plate 8. The lifting plate 9 can clean the impurities attached to the inner wall of the inner cylinder 6 along with the filtered debris. One end of the hydraulic cylinder 7 is fixedly connected to the lifting plate 9 via a connecting rod. A second filter plate 10 is fixedly installed between the inner cylinder 6 and the outer shell 1. Filter holes 11 are provided on the first filter plate 8, the lifting plate 9, and the second filter plate 10. A first packing area 12 is provided in the inner cavity of the inner cylinder 6 above the first filter plate 8. A second packing area 13 is provided in the inner cavity of the outer shell 1 above the second filter plate 10. A sewage pipe 3 is located at one end of the inner cavity of the outer shell 1 and communicates with the inner cylinder 6. A clean water pipe 4 is located at one end of the inner cavity of the outer shell 1 below the second packing area 13. A flushing pipe 14 is also provided at the top of the outer shell 1. The flushing pipe 14 extends from one end of the inner cavity of the outer shell 1 to the inner cylinder 6.

[0022] Furthermore, the first filling zone 12 is filled with crushed stone.

[0023] Furthermore, the second filler zone 13 is filled with activated alumina particles.

[0024] Furthermore, one end of the top of the inner cylinder 6 is higher than the first packing zone 12 and the second packing zone 13.

[0025] Working principle: Raw water enters the bottom of the inner cylinder 6 through the sewage pipe 3. As the raw water is injected, it rises continuously through the first packing zone 12 and flows through the second packing zone 13 to the clean water pipe 14 at the bottom of the second packing zone 13. The raw water first undergoes particle filtration through the lifting plate 9, the first filter plate 8, and the first packing zone 12, and then undergoes defluorination through the second packing zone 13. When it is necessary to clean the inner cavity and inner wall of the inner cylinder 6, the sewage pipe 3 and the clean water pipe 4 are closed, and the switch valve on the drain pipe 5 is opened. The hydraulic cylinder 7 drives the lifting plate 9 to descend. The lifting plate 9 can not only scrape off the debris on the inner wall of the inner cylinder 6, but also push the debris out through the drain pipe 6. Then, clean water is flushed into the inner cylinder 6 through the flushing pipe 14. The flushed clean water continuously seeps down and can flush the first packing zone 12 inside the inner cylinder 6.
