DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] Reference Figure 1-4 A sewage reuse device for environmental management includes a first water filter barrel 1 and a second water filter barrel 2. A coarse water filter plate 9 is installed inside the first water filter barrel 1, and a plurality of scrapers 10 are arranged above the coarse water filter plate 9. A connecting pipe 3 is fixedly connected between the first water filter barrel 1 and the second water filter barrel 2, and a flap 18 is installed at the end of the connecting pipe 3. A pressing plate 13 and a fine water filter plate 15 are installed inside the second water filter barrel 2, and a water collecting chamber 6 is threadedly installed at the lower part of the second water filter barrel 2.

[0023] A plurality of slide grooves 12 are provided on the inner wall of the first water filter barrel 1, and the coarse water filter plate 9 is slidably connected to the inner surface of the first water filter barrel 1 through the slide grooves 12. A mounting column 8 is rotatably installed on the inner bottom surface of the first water filter barrel 1, and the top of the mounting column 8 penetrates the coarse water filter plate 9 upward. A connecting ring 11 is clamped on the top of the mounting column 8, and the connecting ring 11 is clamped on the top of the mounting column 8. When the servo motor 7 drives the mounting column 8 to rotate, it can also drive the scraper 10 to scrape the upper surface of the coarse water filter plate 9 to scrape off the dirt accumulated on the surface. When there is too much dirt, the connecting ring 11 can be removed and the coarse water filter plate 9 can be taken out upward for cleaning.

[0024] Several scrapers 10 are fixedly connected to the outer surface of the connecting ring 11, and a servo motor 7 is fixedly installed on the outer bottom surface of the first water filter barrel 1. The rotating shaft of the servo motor 7 is coaxially fixedly connected to the mounting column 8, and the lower surfaces of the scrapers 10 are in contact with the upper surface of the coarse water filter plate 9.

[0025] The connecting pipe 3 is connected to the first water filter barrel 1 and the second water filter barrel 2. The connecting pipe 3 is higher at the top and lower at the bottom. A water pump 5 is installed at the upper end of the connecting pipe 3. A connecting plate 17 is fixedly installed on the inner surface of the lower end of the connecting pipe 3. The front side surface of the connecting plate 17 is hinged to the flap 18 through a torsion spring, and a sealing gasket 19 is fixedly installed on the rear side surface of the flap 18.

[0026] The water pump 5 draws the sewage filtered by the coarse water filter plate 9 and makes it enter the second water filter barrel 2 along the connecting pipe 3. When the sewage passes through the flap 18, the flap 18 is pushed outward. When there is no water in the connecting pipe 3, the torsion spring drives the flap 18 to reset, and when the pressure plate 13 is pressed down, the flap 18 cannot be flipped into the connecting pipe 3, thereby preventing the water in the second water filter barrel 2 from flowing back into the connecting pipe 3.

[0027] A plurality of connecting grooves 16 are provided on the inner surface of the second water filter barrel 2, and the pressure plate 13 is slidably connected to the inner surface of the second water filter barrel 2 through the connecting grooves 16. A plurality of return springs 14 are fixedly installed on the upper surface of the pressure plate 13, and the ends of the plurality of return springs 14 are fixedly connected to the inner top surface of the second water filter barrel 2. A pressurized air pump 4 is fixedly installed on the outer top surface of the second water filter barrel 2, and the pressurized air pump 4 is connected to the interior of the second water filter barrel 2. The pressurized air pump 4 pressurizes and inflates the upper side of the pressure plate 13 to press the pressure plate 13 downward along the inner surface of the second water filter barrel 2, and quickly presses the sewage inside the second water filter barrel 2 downward through the fine water filter plate 15, and enters the water collecting chamber 6 for centralized discharge.

[0028] The fine water filter plate 15 is placed on the inner bottom surface of the second water filter bucket 2. The water collecting chamber 6 is an inverted cone. After screwing on the water collecting chamber 6, the fine water filter plate 15 can be confined inside the second water filter bucket 2 to prevent it from falling. A water outlet is provided at the bottom of the water collecting chamber 6, and a valve is installed inside the water collecting chamber 6.

[0029] Working principle: When the sewage recycling device for environmental treatment is in use, sewage enters from the upper opening of the first filter bucket 1, and the top of the mounting column 8 is clamped with a connecting ring 11. The connecting ring 11 is clamped on the top of the mounting column 8. When the servo motor 7 drives the mounting column 8 to rotate, it can also drive the scraper 10 to scrape the upper surface of the coarse filter plate 9 to scrape off the dirt accumulated on the surface. When there is too much dirt, the connecting ring 11 can be removed and the coarse filter plate 9 can be taken out upward for cleaning. The water pump 5 extracts the sewage filtered by the coarse filter plate 9 and makes it flow along the connecting pipe 3. The filtrate enters the second water filter barrel 2, and when the sewage passes through the flap 18, the flap 18 is pushed outward. When there is no water in the connecting pipe 3, the torsion spring drives the flap 18 to reset, and when the pressure plate 13 is pressed down, the flap 18 cannot be turned into the connecting pipe 3, so as to prevent the water in the second water filter barrel 2 from flowing back into the connecting pipe 3. The pressurized air pump 4 pressurizes and inflates the pressure plate 13 to make the pressure plate 13 press down along the inner surface of the second water filter barrel 2, and the sewage in the second water filter barrel 2 is quickly pressed down through the fine water filter plate 15, and enters the water collecting chamber 6 and is discharged centrally.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
