DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-Figure 4 A domestic sewage grading treatment device includes a treatment pool 5, a partition 7 is provided inside the treatment pool 5, and the edges of the partition 7 are fixed on the inner wall of the treatment pool 5. The treatment pool 5 can be separated by the partition 7, so that the treatment pool 5 can perform multi-stage treatment on sewage.

[0029] It should be noted that the top of the partition 7 is lower than the top of the treatment tank 5. In actual use, when the sewage at one end of the treatment tank 5 overflows the top of the partition 7, the sewage will flow along the top of the partition 7 to the other end of the treatment tank 5 for subsequent treatment.

[0030] like Figure 3 As shown, a second guide plate 19 is installed inside the treatment pool 5 and on both sides of the partition 7. Both sides of the top of the second guide plate 19 are inclined, and the second guide plate 19 is fixed to the bottom of the treatment pool 5. The second guide plate 19 can guide the sewage and stains in the treatment pool 5 so that the sewage and stains gather at the lowest end of the second guide plate 19 for easy discharge.

[0031] Drain pipes 1 are installed on the sides of the treatment tank 5 , respectively. The ends of the drain pipes 1 are located above the second guide plate 19 . The dirt deposited at the bottom of the treatment tank 5 can be discharged through the drain pipes 1 .

[0032] like Figure 1 As shown, a reagent tank 4 is installed on one side of the top of the treatment tank 5 through a bracket, a delivery pipe 6 is installed on the bottom of the reagent tank 4, the bottom of the delivery pipe 6 extends to the inside of the treatment tank 5, and a water inlet pipe 2 is fixedly installed on one side of the treatment tank 5, one end of the water inlet pipe 2 is fixed on the side of the delivery pipe 6. In actual use, sewage can be transported to the delivery pipe 6 through the water inlet pipe 2, and then transported to the treatment tank 5 through the delivery pipe 6 for treatment. While transporting the sewage, the flocculant in the reagent tank 4 can be transported to the treatment tank 5 together with the sewage through the delivery pipe 6, so as to fully contact with the sewage and be fully mixed.

[0033] like Figure 2 As shown, the internal rotation of the medicine tank 4 is connected to a rotating shaft 16, the bottom of the rotating shaft 16 extends into the inside of the delivery pipe 6, and a plurality of fan blades 18 are installed on the bottom side of the rotating shaft 16. There is a distance between the edge of the fan blade 18 and the inner wall of the delivery pipe 6. In actual use, when sewage is transported along the delivery pipe 6, the sewage will impact the fan blade 18, and then the fan blade 18 will rotate, causing the rotating shaft 16 to rotate along with the fan blade 18.

[0034] It should be noted that the end of the water inlet pipe 2 close to the delivery pipe 6 is located above the fan blades 18, and the fan blades 18 are higher than the top of the partition 7. In this way, the fan blades 18 will always be located above the sewage level in the treatment tank 5, and will not affect the impact force of the sewage on the fan blades 18 when moving in the delivery pipe 6.

[0035] like Figure 2 As shown, a spiral blade 17 is also installed on the side of the rotating shaft 16, the top of the spiral blade 17 is located inside the medicine tank 4, the bottom of the spiral blade 17 is located inside the conveying pipe 6, and the edge of the spiral blade 17 is matched with the inner wall of the medicine tank 4 and the inner wall of the conveying pipe 6. In actual use, the rotation of the fan blade 18 will drive the spiral blade 17 to rotate through the rotating shaft 16. When the spiral blade 17 rotates, it will convey the flocculant in the medicine tank 4 to the conveying pipe 6. In this way, the flow rate of the sewage will control the rotation speed of the fan blade 18, and then control the speed of the flocculant feeding, so that the flocculant can be delivered according to the flow rate of the sewage, thereby improving the use effect.

[0036] like Figure 3 and Figure 4As shown, two mounting plates 13 are connected to one end of the treatment pool 5 away from the medicine tank 4, each mounting plate 13 is set in an "S" shape, and one end of each mounting plate 13 extends to the outside of the treatment pool 5, and a number of support shafts 14 are rotatably connected between the two mounting plates 13, and the support shafts 14 are connected by a conveyor belt 9, and the conveyor belt 9 is a mesh structure. A sprocket 21 is installed at both ends of each support shaft 14, and the sprockets 21 on two adjacent support shafts 14 are connected by a chain, and one end of one of the support shafts 14 is connected to a drive motor 15, which is fixed on the mounting plate 13. In actual use, the conveyor belt 9 can be driven to move by the drive motor 15, so that after the sewage is precipitated, the part that overflows the partition 7 will flow to the surface of the conveyor belt 9, and after being filtered by the conveyor belt 9, the impurities will be transmitted to the outside of the treatment pool 5 along the conveyor belt 9, and the filtered water will flow to the bottom of the conveyor belt 9.

[0037] It should be noted that first guide plates 8 are installed on both sides of the treatment pool 5 close to the mounting plate 13 and on the sides of the partition 7. The top of the first guide plate 8 is tilted, and one side of each first guide plate 8 extends to the top of the conveyor belt 9. During actual use, the sewage will flow directly to the surface of the conveyor belt 9 under the guidance of the first guide plate 8, so that the sewage can be fully filtered.

[0038] It should be noted that a drain pipe 10 is installed on the side of the treatment pool 5 near one end of the conveyor belt 9, and one end of the drain pipe 10 is aligned with the top of the second guide plate 19, so that the sewage filtered by the conveyor belt 9 can be discharged through the drain pipe 10.

[0039] Specifically, when the utility model is in use, the staff transports the sewage to the delivery pipe 6 through the water inlet pipe 2, and the sewage is then transported to the treatment tank 5 along the delivery pipe 6. When the sewage flows in the delivery pipe 6, it will impact the fan blades 18, causing the fan blades 18 to rotate, which will drive the rotating shaft 16 and the spiral blades 17 to rotate. The flocculant in the reagent tank 4 is transported to the delivery pipe 6 under the action of the spiral blades 17, mixed with the sewage, and mixed fully. A preset amount of flocculant can be added according to the flow rate of the sewage. After that, the sewage flows into the treatment tank 5 after mixing with the flocculant. Impurities in the sewage gather and settle at the bottom of one end of the treatment tank 5. The top blades of the sewage will fall on the conveyor belt 9 after overflowing the partition 7. The remaining stains in the sewage are filtered out by the conveyor belt 9, and the filtered water flows to the bottom of the conveyor belt 9. While the conveyor belt 9 is filtering the stains in the sewage, the drive motor 15 works. The drive motor 15 will drive the conveyor belt 9 to move under the action of the support shaft 14 to transport and discharge the filtered stains.

[0040] Furthermore, Figure 1As shown, a top cover 3 is connected to one side of the top of the medicine tank 4 through a hinged seat, and the top cover 3 covers the top of the medicine tank 4. In actual use, flocculant can be added into the medicine tank 4 by opening the top cover 3.

[0041] like Figure 3 As shown, the bending parts of the conveyor belt 9 are symmetrically provided with limiting wheels 20, one end of each limiting wheel 20 is rotatably connected to the mounting plate 13, and the side of the limiting wheel 20 is in contact with the conveyor belt 9. Under the action of the limiting wheel 20, the conveyor belt 9 will be limited, so that the conveyor belt 9 is matched with the mounting plate 13, which is convenient for conveying the stains filtered out by the conveyor belt 9.

[0042] Furthermore, Figure 1 and Figure 3 As shown, a scraper 12 is installed at one end of the top of the treatment tank 5. The scraper 12 is inclined, and the top of the scraper 12 is gap-matched with the bottom of the conveyor belt 9. In actual use, the sewage dripping from the conveyor belt 9 will fall on the scraper 12 and flow back to the treatment tank 5 along the scraper 12. The scraper 12 can also scrape off the stains adhering to the conveyor belt 9 to prevent the stains from falling into the treatment tank 5.

[0043] like Figure 1 As shown, strip baffles 11 are vertically installed on both sides of the scraper 12, and the top of the strip baffles 11 extends above the scraper 12. Under the action of the strip baffles 11, the sewage flowing on the scraper 12 can be blocked to prevent the sewage from leaking from both sides of the scraper 12.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
