Detailed Implementation Modes

[0031] Next, in combination with the drawings in the specification of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Referring to Figure 1-2 , an embodiment provided by the present utility model: a wastewater filtering device for water conservancy projects, including a barrel body 1. A motor 2 is fixedly connected to the middle of the bottom surface of the barrel body 1. The output end of the motor 2 is fixedly connected to a stirring rod 3. The top of the stirring rod 3 is rotatably connected to the middle of the inner wall top surface of the barrel body 1. A separating mechanism is arranged inside the barrel body 1; the separating mechanism includes a convex block 4, an inclined surface ring 5, a water outlet pipe 6 and a sewage discharge pipe 7. The bottom surface of the convex block 4 is fixedly connected to the middle of the inner wall bottom surface of the barrel body 1. The bottom of the stirring rod 3 is rotatably connected to the middle of the convex block 4. The bottom of the inclined surface ring 5 is fixedly connected to one side of the inner wall bottom surface of the barrel body 1. One side of the inclined surface ring 5 is fixedly connected to one side of the outer wall of the convex block 4. One end of the water outlet pipe 6 is fixedly connected to the middle and lower part of one side of the outer wall of the barrel body 1. The top of the sewage discharge pipe 7 is fixedly connected to one side of the bottom surface of the barrel body 1. When the wastewater and the liquid medicine enter the inside of the barrel body 1, the driving motor 2 can drive the stirring rod 3 to rotate. By using the rotation of the stirring rod 3, the wastewater can be driven to move, so that the wastewater and the medicine are evenly mixed. At this time, after standing for a period of time, the solid impurities in the wastewater can settle, and through the cooperation between the convex platform and the inclined surface ring 5, the solid impurities in the wastewater can roll along the inclined surface ring 5 and finally enter the left side of the inner bottom of the barrel body 1. Therefore, it can be avoided that the solid impurities in the wastewater enter the inside of the water outlet pipe 6 along with the wastewater, and thus the phenomenon of blockage of the water outlet pipe 6 can be avoided.

[0033] Referring to Figure 1 , a support leg 8 is fixedly connected to the outside of the middle of the bottom surface of the barrel body 1. A support plate 9 is fixedly connected to the bottom of the support leg 8. The bottom of the motor 2 is fixedly connected to the middle of the top surface of the support plate 9. A first valve 10 is arranged in the middle of the water outlet pipe 6. A second valve 11 is arranged in the middle of the sewage discharge pipe 7. When the precipitation of the solid impurities is completed, by opening the first valve 10, the wastewater can be discharged from the water outlet pipe 6, and by opening the second valve 11, the solid impurities can be discharged from the sewage discharge pipe 7.

[0034] Referring to Figure 2-3, on the left side of the top surface of the barrel body 1, a water inlet 12 is provided, and a water inlet pipe 13 is fixedly connected to the middle of the water inlet 12. At the middle and lower part on the right side of the outer wall of the barrel body 1, a water outlet 14 is provided. One end of the water outlet pipe 6 is inside the water outlet 14. On the left side of the bottom surface of the barrel body 1, a sewage outlet 15 is provided. The top of the sewage pipe 7 is inside the sewage outlet 15, and the bottom surface of the water outlet 14 and the top surface of the inclined plane ring 5 are at the same height. Through the water inlet 12, waste water can enter the inside of the barrel body 1. Through the water outlet 14 and the sewage outlet 15, waste water and solid impurities can be discharged from the barrel body 1.

[0035] Refer to Figure 3-4 , on the rear side of the top surface of the barrel body 1, a telescopic rod 16 is fixedly connected. The output end of the telescopic rod 16 is fixedly connected with a plug board 18. One end of the plug board 18 is slidably connected to the inner bottom of the feeding hopper 17. The bottom of the feeding hopper 17 is fixedly connected to the front side of the middle part of the top surface of the barrel body 1. At the front side of the middle part of the top surface of the barrel body 1, a feeding port 19 is provided. The feeding hopper 17 is communicated with the barrel body 1 through the feeding port 19. On the top of the front side of the outer wall of the barrel body 1, a transparent plate 20 is fixedly connected. Scale lines 21 are arranged on the outside of the transparent plate 20, and the feeding hopper 17 is made of colorless transparent material. By driving the telescopic rod 16 to extend its output end to push out the plug board 18, the plug board 18 slides inside the feeding hopper 17, so as to seal the inner bottom of the feeding hopper 17. Since the space at the inner bottom of the feeding hopper 17 is sealed, when the medicament enters the feeding hopper 17, it will be retained inside. At the same time, the feeding hopper 17 is made of colorless transparent material, so the addition amount of the medicament can be observed. Finally, by driving the telescopic rod 16 to retract its output end, at this time, the medicament can enter the inside of the barrel body 1 along the feeding hopper 17, and the specific amount of waste water entering the inside of the barrel body 1 can be known through the transparent plate 20 and the scale lines 21. Therefore, the ratio between the waste water and the medicament can be controlled, so as to improve the treatment quality of the waste water.

[0036] Working principle: When in use, first close the first valve 10 and the second valve 11. Subsequently, drive the telescopic rod 16 to extend its output end to push out the plug plate 18, so that the plug plate 18 slides inside the feed hopper 17, thereby sealing the inner bottom of the feed hopper 17. Then, wastewater can enter the inside of the barrel 1 through the water inlet pipe 13. When the wastewater enters the inside of the barrel 1, add the medicament into the inside of the feed hopper 17. Since the space at the inner bottom of the feed hopper 17 is sealed, the medicament will remain inside the feed hopper 17. At the same time, the feed hopper 17 is made of colorless transparent material, so the addition amount of the medicament can be observed. Finally, drive the telescopic rod 16 to retract its output end. At this time, the medicament can enter the inside of the barrel 1 along the feed hopper 17. When the medicament enters the inside of the barrel 1, drive the motor 2 to drive the stirring rod 3 to rotate at this time. The rotation of the stirring rod 3 can drive the wastewater to move, so that the wastewater and the medicament are evenly mixed. At this time, let it stand for a period of time, and the solid impurities in the wastewater can settle. And through the cooperation between the convex platform and the inclined surface ring 5, the solid impurities in the wastewater can roll along the inclined surface ring 5 and finally enter the left side of the inner bottom of the barrel 1. Therefore, it can be avoided that the solid impurities in the wastewater enter the inside of the water outlet pipe 6 along with the wastewater, and thus the phenomenon of blockage of the water outlet pipe 6 can be avoided. When the precipitation of the solid impurities is completed, open the first valve 10 to discharge the wastewater from the water outlet pipe 6. Open the second valve 11 to discharge the solid impurities from the sewage pipe 7. And when the wastewater enters the inside of the barrel 1, the specific amount of the wastewater entering the inside of the barrel 1 can be known through the transparent plate 20 and the scale line 21. Therefore, the ratio between the wastewater and the medicament can be controlled, thereby improving the treatment quality of the wastewater.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
