[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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] Refer to Figures 1 - 3, An embodiment provided by the present utility model: A rapid separation device for water pollution treatment, comprising a housing 1, a connecting pipe 4 fixedly connected inside the housing 1, a first motor 5 fixedly connected to one side of the housing 1, a first conical barrel 6 fixedly connected to the output end of the first motor 5, a screw blade 7 fixedly connected to the outer wall of the first conical barrel 6, a separation component arranged inside the housing 1, a second conical barrel 11 fixedly connected inside the first conical barrel 6, a through hole 8 opened inside the first conical barrel 6, one end of the connecting pipe 4 passing through the inside of the second conical barrel 11, a grille 10 fixedly connected inside the housing 1, a drain pipe 2 fixedly connected to the bottom of the housing 1, a sludge pipe 3 fixedly connected to the other side of the housing 1, and the separation component includes a partition plate 9, the outer wall of the partition plate 9 being fixedly connected inside the housing 1, and one end of the first conical barrel 6 being rotatably connected inside the partition plate 9;

[0033] Specifically, during the sewage treatment process, the sewage is pumped out from the inside of the chemical dosing tank 12 through the input end of the sludge pump 13, and the output end of the sludge pump 13 then pumps the sewage into the inside of the second conical barrel 11 through the connecting pipe 4. The output end of the first motor 5 drives the first conical barrel 6 to start rotating at a high speed. This rotation action causes the sewage and sludge to generate a strong centrifugal force inside the first conical barrel 6, and thus flow out through the through hole 8. Since the mass of the sewage is relatively light, under the action of the centrifugal force, the sewage is thrown out by the first conical barrel 6 and falls to the bottom through the grille 10. This process not only realizes the preliminary separation of the sewage but also provides convenience for the subsequent treatment processes. The sewage filtered by the grille 10 is discharged through the drain pipe 2 to the next process. In this process, the design of the drain pipe 2 ensures the smooth discharge of the sewage, avoiding the interruption of the treatment caused by blockage. At the same time, the material and connection method of the drain pipe 2 also ensure its stability and durability during use. Meanwhile, the sludge is left inside the first conical barrel 6 through the filtering action of the grille 10. Since the mass of the sludge is heavier, they will not be thrown out like the sewage. At this time, the auxiliary conveying function of the screw blade 7 starts to play. The screw blade 7 conveys the sludge from one side of the first conical barrel 6 to the other side through rotation, enabling the sludge to smoothly enter the sludge pipe 3 through the partition plate 9, and the sludge is discharged through the sludge pipe 3 to the next treatment process.

[0034] Refer to Figure 1 , Figure 4 and Figure 5, a chemical dosing tank 12 is provided on one side of the housing 1. A chemical dosing port 14 is provided at the top of the chemical dosing tank 12. A sewage pipe 15 is fixedly connected inside the chemical dosing tank 12. A sludge pump 13 is fixedly connected to the outer wall of the chemical dosing tank 12. The input end of the sludge pump 13 is fixedly connected inside the chemical dosing tank 12. The output end of the sludge pump 13 is fixedly connected to the other end of the connecting pipe 4. A second motor 16 is fixedly connected to the top of the chemical dosing tank 12. The output end of the second motor 16 is fixedly connected to a driving gear 17. A connecting shaft 18 is rotatably connected inside the chemical dosing tank 12. One end of the connecting shaft 18 is fixedly connected to a driven gear 19. The driven gear 19 meshes with the outer wall of the driving gear 17. The other end of the connecting shaft 18 is fixedly connected to a frame 20. A limiting ring 21 is rotatably connected inside the frame 20. One end of the limiting ring 21 is fixedly connected to a stirring blade 22. The other end of the limiting ring 21 is fixedly connected to a first bevel gear 23. A third motor 26 is fixedly connected to the top of the driven gear 19. The output end of the third motor 26 is fixedly connected to a rotating shaft 24. One end of the rotating shaft 24 is fixedly connected to a second bevel gear 25. The second bevel gear 25 meshes with the outer wall of the first bevel gear 23;

[0035] Specifically, inside the chemical dosing tank 12, the flocculant is precisely injected into the sewage through the chemical dosing port 14. The main function of the flocculant is to cause a flocculation reaction of the fixed suspended solids in the sewage, that is, these suspended solids will aggregate together to form larger particles, thus facilitating separation from water. With the addition of the flocculant, obvious changes occur to the suspended solids in the sewage. The tiny particles originally dispersed in the water gradually aggregate together to form larger flocs. These flocs gradually settle to the bottom of the chemical dosing tank 12 under the action of gravity, thus achieving a preliminary separation from water. However, in order to better mix the sewage and the flocculant and improve the treatment effect, the output end of the second motor 16 starts to play a role. It drives the driving gear 17 to rotate. The driving gear 17 meshes with the driven gear 19. Through the transmission of the gears, the connecting shaft 18 is driven to rotate. The rotation of the connecting shaft 18 further drives the rotation of the frame 20. A plurality of stirring blades 22 are installed on the frame 20. These stirring blades 22 start to rotate inside the chemical dosing tank 12 under the drive of the frame 20. The rotation of the stirring blades 22 enables the sewage and the flocculant to be fully mixed, thus improving the reaction efficiency. In order to improve the mixing efficiency, the output end of the third motor 26 drives the rotating shaft 24 to rotate, and the rotating shaft 24 is transmitted through the second bevel gear 25 and the first bevel gear 23. When the first bevel gear 23 rotates, the stirring blade 22 connected thereto will correspondingly change its inclination angle. The power supply method of the third motor 26 is the contact power supply of the carbon brush and the metal ring. The metal ring is connected to the power supply port of the third motor 26, so that the power supply carbon brush contacts the metal ring to supply power to the third motor 26, in order to prevent the power cord of the third motor 26 from being wound when the third motor 26 follows the driven gear 19 to rotate.

[0036] Working principle: When using this rapid separation device for water pollution treatment, first, the sewage to be treated enters the inside of the chemical dosing tank 12 through the sewage pipe 15. Subsequently, a flocculant is injected into the chemical dosing tank 12 through the chemical dosing port 14. The flocculant can flocculate the fixed suspended solids in the sewage and separate them from the water. Then, the output end of the second motor 16 drives the driving gear 17 to rotate. The driving gear 17 drives the connecting shaft 18 to rotate through the driven gear 19. The connecting shaft 18 drives the stirring blade 22 to rotate through the frame 20 to mix the sewage and the flocculant in the chemical dosing tank 12. When adjusting the inclination angle of the stirring blade 22 to improve the mixing efficiency, the output end of the third motor 26 drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the first bevel gear 23 to rotate through the second bevel gear 25. Furthermore, the stirring blade 22 adjusts the contact area between the stirring blade 22 and the sewage through the rotation of the first bevel gear 23, improving the stirring efficiency of the sewage and the flocculant. Then, the fully mixed sewage is pumped out from the inside of the chemical dosing tank 12 through the input end of the sludge pump 13. Subsequently, the output end of the sludge pump 13 is pumped into the inside of the second conical barrel 11 through the connecting pipe 4. Then, the output end of the first motor 5 drives the first conical barrel 6 to rotate at a high speed, so that the sewage and the sludge flow out through the through hole 8. Since the sewage is lighter in mass, it is thrown out through the first conical barrel 6, falls through the grille 10 to the bottom, and is discharged through the drain pipe 2 to the next process. Subsequently, the sludge is filtered by the grille 10 and, due to the heavier mass of the sludge, is transported to the other side of the partition plate 9 with the assistance of the auger blade 7, so that the sludge is discharged through the sludge pipe 3 to the next treatment process.

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 for some of the technical features.
