[0023] Please refer to Figures 1 to 4 In the embodiments of the utility model, a water treatment denitrification device includes a denitrification tank 1, support blocks 2 are fixedly installed on both sides of the bottom of the denitrification tank 1, a filter box 10 is fixedly inserted and installed on the top of the denitrification tank 1, filter screens 15 are fixedly embedded and installed on both sides of the inside bottom of the filter box 10, a mounting frame 13 is fixedly installed on one side of the top of the denitrification tank 1, a motor 12 is fixedly installed on the top of the mounting frame 13, the driving end of the motor 12 penetrates the top of the mounting frame 13 and extends above the top of the filter box 10, a vertical shaft 9 is fixedly installed on the driving end of the motor 12, the bottom end of the vertical shaft 9 penetrates the bottom of the inner wall of the filter box 10 and extends below the inside of the denitrification tank 1, a plurality of rotating shafts 7 are rotatably installed on the outer wall of the vertical shaft 9, a plurality of stirring sticks 8 are fixedly installed on the outer wall of the rotating shaft 7, a dosing pipe 14 is fixedly inserted and installed above one side of the denitrification tank 1, and a discharge pipe 3 is fixedly inserted and installed on the bottom of the denitrification tank 1.

[0024] Refer to Figure 1 and Figure 4In the application, the outer wall of the vertical shaft 9 is fixedly sleeved with a cam plate 16, and the cam plate 16 is located in the interior of the filter box 10. The two sides of the filter box 10 are slidably and penetratingly installed with slide rods 22. The opposite ends of the two slide rods 22 are fixedly installed with pressing plates 17. The bottom of the pressing plate 17 is fixedly installed with a scraper 23, and the scraper 23 is in sliding contact with the upper surface of the filter screen 15. One end of the slide rod 22 located outside the filter box 10 is fixedly installed with a baffle 21. The outer wall of the slide rod 22 is sleeved with a spring 18 between the pressing plate 17 and the inner wall of the filter box 10, so that the pressing plate 17 makes a transverse reciprocating motion. The movement of the pressing plate 17 drives the scraper 23 to move, so that the scraper 23 scrapes the upper surface of the filter screen 15. The impurities and sludge filtered by the filter screen 15 are scraped to the two sides, so that the excessive impurities and sludge filtered on the upper surface of the filter screen 15 do not cause the blockage of the filter screen 15, and the passability of the filter screen 15 is affected.

[0025] Referring to Figure 1 In the application, a plurality of annular racks 5 are fixedly installed on the inner wall of the denitrification tank 1. A gear 6 is fixedly installed at the end of the rotating shaft 7 away from the vertical shaft 9, and the gear 6 is engaged with the annular rack 5. When the stirring rod 8 rotates along with the vertical shaft 9, it also rotates along with the rotating shaft 7, so that the liquid in the denitrification tank 1 is stirred in multiple directions.

[0026] Referring to Figure 1 In the application, a support frame 4 is fixedly installed on the bottom of the inner wall of the denitrification tank 1, and the support frame 4 is rotatably connected to the bottom end of the vertical shaft 9 through the bearing installed on the top of the support frame 4, so that the stability of the stirring mechanism during rotation is improved.

[0027] Referring to Figure 4 In the application, sealing sliding sleeves 19 corresponding to the positions of the slide rods 22 are fixedly and penetratingly installed on the two sides of the filter box 10, and the sealing sliding sleeves 19 are slidably connected to the corresponding slide rods 22. The baffle 21 is fixedly connected to the side surface of the filter box 10 through the telescopic rod 20. The sealing sliding sleeves 19 ensure the sealing of the sliding connection between the slide rods 22 and the filter box 10. The telescopic rod 20 ensures the stability of the slide rods 22 during transverse movement, so that the slide rods 22 do not rotate with the sealing sliding sleeves 19, and the stability of the movement of the scraper 23 is ensured.

[0028] Referring to Figure 1 and Figure 2 In the application, a limiting frame 11 is fixedly installed on the other side of the filter box 10 at the top of the denitrification tank 1. A visual transparent glass 24 is fixedly and inlaidly installed on one side of the front of the denitrification tank 1. The outer surface of the visual transparent glass 24 is provided with scale lines. Through the limiting frame 11, the outside regenerated water pipeline is conveniently fixed, manual water adding is not needed, and the amount of regenerated water in the denitrification tank 1 can be observed at any time through the visual transparent glass 24, so that the addition of regenerated water can be stopped in time.

[0029] The working principle of this utility model is as follows:

[0030] Reference Figures 1 to 4 In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. The reclaimed water pipeline is fixed by the limiting bracket 11, and then the reclaimed water is directly discharged into the filter box 10. After the reclaimed water enters the filter box 10, the filter screen 15 at the bottom of the filter box 10 filters the reclaimed water, removing impurities and sludge. The filtered reclaimed water enters the denitrification tank 1 and can be observed through the transparent glass 24. When the amount of reclaimed water in the denitrification tank 1 reaches a certain level, the addition of reclaimed water is stopped. At this time, the liquid level of the reclaimed water in the denitrification tank 1 is below the bottom of the filter box 10. At the same time, the denitrification is treated through the dosing pipe 14. An appropriate amount of denitrification agent is added to the inside of the denitrification tank 1, and the motor 12 is started to work by controlling the switch. The drive end of the motor 12 drives the vertical shaft 9 to rotate, and the rotation of the vertical shaft 9 drives the rotating shaft 7 to rotate. The stirring rod 8 rotates with the rotating shaft 7. The rotating stirring rod 8 and the rotating shaft 7 will stir the regenerated water filtered inside the denitrification tank 1 and the denitrification agent, so that they are fully mixed and react quickly. The regenerated water that has completed the denitrification treatment can be discharged through the discharge pipe 3. The entire denitrification operation of the regenerated water inside the denitrification tank 1 does not come into contact with the filter box 10, so that the impurities and sludge filtered out inside the filter box 10 do not come into contact with the denitrification agent, avoiding the consumption of denitrification agent and improving the practicality of the device.

[0031] Reference Figure 1 , Figure 3 and Figure 4 During use, when filtering reclaimed water through the filter screen 15 inside the filter box 10, the vertical shaft 9 is driven by the motor 12 to rotate. The rotation of the vertical shaft 9 drives the cam plate 16 to rotate. The rotation of the cam plate 16 causes the two pressure plates 17 to press intermittently. With the elastic action of the spring 18, the pressure plates 17 make a horizontal reciprocating motion. The movement of the pressure plates 17 drives the scraper 23 to move, causing the scraper 23 to scrape the upper surface of the filter screen 15. The impurities and silt filtered by the filter screen 15 are scraped to both sides, avoiding excessive impurities and silt on the upper surface of the filter screen 15, which would cause the filter screen 15 to become clogged and affect the passivity of the filter screen 15. By continuously scraping the upper surface of the filter screen 15, impurities and silt cannot remain still and adhere to the upper surface of the filter screen 15, ensuring the passivity of the filter screen 15 and facilitating the stable operation of the device.

[0032] Reference Figure 1When in use, as the rotating shaft 7 rotates along with the vertical shaft 9, it drives the gear 6 to mesh with the ring rack 5, causing the gear 6 to drive the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 drives the stirring rod 8 to rotate. Therefore, the stirring rod 8 rotates along with the rotating shaft 7 while rotating with the vertical shaft 9, which makes the liquid inside the denitrification tank 1 stirred in multiple directions, making the liquid move randomly. This further improves the mixing speed of the denitrification agent and the regenerated water, resulting in high uniformity and fast reaction efficiency, thus further improving the efficiency of the device.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
