The output shaft of the second motor 17 is connected to a stirring rod 18, and a filter paper 19 is provided below the filter device 16. The sedimentation and filtering equipment uses a salvage device 7 floating on the water surface to rotate and salvage floating objects on the water surface. Impurities in the water are deposited at the bottom of the sedimentation tank 3. The first motor 8 drives the cleaning device 9 to rotate and scrape off the sediment. The cover plate 28 approaches and adsorbs on the scraper 27 under the impact of the water flow, thereby sealing the sediment and preventing the sediment from polluting water resources again. The sediment flows into the slag collecting tank 4 and is collected on the filter net bag 31. After sedimentation, the water is initially filtered by the filter net 15. The stirring rod 18 rotates to form a vortex to accelerate the filtration efficiency when passing through the filter device 16. Finally, it is filtered again through the filter paper 19. During the sedimentation process, the sediment and floating objects are collected separately, which improves the sedimentation quality, makes the water flow form a vortex to accelerate the filtration efficiency, and improves the filtration speed.

[0028] In this embodiment, if Figure 1-Figure 3 As shown, the salvage device 7 includes a third motor 20 fixed to the top of the inner wall of the sedimentation tank 3, the output shaft of the third motor 20 is connected to a mounting plate, and a plurality of automatic telescopic rods 21 are provided at the bottom of the mounting plate.

[0029] In this embodiment, if Figure 5-Figure 8As shown, the cleaning device 9 includes a connecting plate 25 connected to the output shaft of the first motor 8, a plurality of fixed plates 26 are connected to the side wall of the connecting plate 25, a scraper 27 is provided on one side of the fixed plate 26, and a cover plate 28 is connected to the top of the scraper 27 through a plurality of hinges. The cover plate 28 is a fan-shaped cover plate, and the fixed plate 26 includes a support plate located on one side of the scraper 27 and an arc-shaped baffle connected to one end of the support plate, and the other end of the baffle is connected to the scraper 27.

When the cleaning device 9 is stationary, the weight of the upper half of the cover plate 28 is lower than that of the lower half due to the cavity, and then the cover plate 28 remains in a vertical state, and the sediment is deposited at the bottom of the sedimentation tank 3, so that too much sediment is prevented from accumulating on the cover plate 28. The first motor 8 drives the cleaning device 9 to rotate and energizes the electromagnet 30. When the cover plate 28 rotates, it approaches the scraper 27 under the impact of the water flow. The iron sheet 29 is coated with an anti-corrosion and anti-rust layer. The iron sheet 29 is adsorbed on the electromagnet 30. The fixed plate 26, the scraper 27 and the cover plate 28 seal an area so that the sediment in the area cannot pollute the water source for a second time. After opening the solenoid valve on the sewer pipe 10, the water and sediment in the cleaning device 9 flow into the slag collecting tank 4, and the sediment is collected in the filter net bag 31. The water in the slag collecting tank 4 and the sedimentation tank 3 is subjected to the next filtration treatment.

[0030] In this embodiment, if Figure 1 and Figure 4 As shown, a plurality of fixing rods 6 are provided on the inner wall of the sedimentation shell 1, and the other ends of the plurality of fixing rods 6 are connected to a central column 5, and the top and bottom of the fixing rods 6 are provided with ultraviolet irradiation lamps 32. A water inlet pipe 2 communicating with the sedimentation tank 3 is provided on the top of the sedimentation shell 1, and a water valve is provided on the water inlet pipe 2.

The sedimentation process takes a long time, and the ultraviolet irradiation lamp 32 is used for disinfection in this process to save time and improve efficiency. The central column 5 plays a role in limiting the position of the float 22, and the water outlet cover 14 increases the contact area between the outlet water and the filter screen 15 to avoid the filter screen 15 from being quickly blocked at a certain position. The stirring rod 18 is installed in the groove to form a vortex in the water flow, increase the contact area between the water flow and the filter screen 15 and accelerate the flow rate of the water flow, and the funnel-shaped filter paper 19 increases the contact area of ​​the water flow and improves efficiency.

[0031] In this embodiment, if Figure 1-Figure 8 As shown, the working process of a precipitation filtration device provided in this embodiment is as follows:

[0032] Step 1: Open the water valve on the sedimentation tank 3 to inject water into the sedimentation tank 3. After the water in the sedimentation tank 3 is precipitated, start the third motor 20 to drive the salvage frame 23 to rotate slowly to salvage the floating objects on the water surface into the salvage net 24. Start the first motor 8 to drive the cleaning device 9 to rotate. The cover plate 28 is driven by the water flow to approach the scraper 27. The iron sheet 29 is sucked by the electromagnet 30. The scraper 27 scrapes off the sediment at the bottom of the sedimentation tank 3. Open the solenoid valve on the sewer pipe 10 and the impurities are collected on the filter net bag 31.

[0033] Step 2: Start the water pump 13 to pump out the water in the sedimentation tank 3 and spray it out from the water outlet cover 14, and then filter it for the first time through the filter screen 15. Start the second motor 17 to drive the stirring rod 18 to rotate so that the water above the filter device 16 forms a vortex and passes through the filter device 16 for secondary filtration, and finally filters it for the third time through the filter paper 19.

[0034] In summary, in this embodiment, according to the sedimentation and filtration equipment of this embodiment, the sedimentation and filtration equipment makes the lower half of the salvage frame 23 below the water surface and the upper half above the water surface through the float 22, the scoop net 24 can filter out excess water and scoop up floating objects in the net, and the third motor 20 drives the salvage frame 23 to rotate slowly to salvage floating objects. When the cleaning device 9 is stationary, the upper half of the cover plate 28 is lighter than the lower half due to the cavity, and then the cover plate 28 remains in a vertical state, and the sediment is deposited at the bottom of the sedimentation tank 3, avoiding excessive sediment accumulation on the cover plate 28. The first motor 8 drives the cleaning device 9 to rotate and energizes the electromagnet 30. When the cover plate 28 rotates, it approaches the scraper 27 under the impact of the water flow. The iron sheet 29 is coated with an anti-corrosion and anti-rust layer. The iron sheet 29 is adsorbed on the electromagnet 30. The fixed plate 26, the scraper 27 and the cover plate 28 seal an area so that the sediment in the area cannot pollute the water source for a second time. After opening the solenoid valve on the sewer pipe 10, the water and sediment in the cleaning device 9 flow into the slag collecting tank 4, and the sediment is collected in the filter net bag 31. The water in the slag collecting tank 4 and the sedimentation tank 3 is subjected to the next filtration treatment. The sedimentation process takes a long time, and an ultraviolet lamp 32 is used for disinfection in this process to save time and improve efficiency. The central column 5 serves to limit the position of the float 22. The water outlet cover 14 increases the contact area between the outlet water and the filter screen 15 to avoid the filter screen 15 from being quickly blocked at a certain position. The stirring rod 18 is installed in the groove to form a vortex in the water flow, increase the contact area between the water flow and the filter screen 15 and accelerate the flow rate of the water flow. The funnel-shaped filter paper 19 increases the contact area of ​​the water flow and improves efficiency.
