DETAILED DESCRIPTION
[0028] 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.
[0029] Reference Figure 1-Figure 6 A sewage and wastewater dosing and precipitation integrated machine includes a sedimentation tank 12, the bottom of the sedimentation tank 12 is fixed on a base 1 through a plurality of legs 13, and a medicine barrel 2 is installed on one side of the base 1. In actual use, Figure 2 As shown, the height of the medicine barrel 2 is lower than that of the sedimentation tank 12, and the medicine can be added into the medicine barrel 2, so that the staff does not need to add the medicine directly into the sedimentation tank 12, and the addition of the medicine is convenient.
[0030] like Figure 5 As shown, a control cabinet 26 is installed on the side of the sedimentation tank 12, and a controller is installed inside the control cabinet 26, which is a control mainboard, a host or a PLC logic controller.
[0031] like Figure 2 and Figure 4As shown, a peripheral edge 11 is installed on the top side of the sedimentation tank 12, and a U-shaped frame 8 with an opening facing downward is installed on the top of the peripheral edge 11. The bottom of the U-shaped frame 8 is rotatably connected with a hollow shaft 25, and the top of the hollow shaft 25 passes through the U-shaped frame 8. The top of the hollow shaft 25 is connected to the second infusion tube 6 through a rotating joint 24. Under the action of the rotating joint 24, the second infusion tube 6 will not rotate with the hollow shaft 25, thereby ensuring that the infusion of the second infusion tube 6 is not affected.
[0032] like Figure 2 or Figure 4 As shown, the other end of the second infusion tube 6 is fixed on the liquid outlet end of the infusion pump 5, and the infusion pump 5 is fixed on the surrounding edge 11 through the mounting plate 4. The water inlet end of the infusion pump 5 is connected to the first infusion tube 3, and the other end of the first infusion tube 3 is fixed to the bottom side of the medicine barrel 2. A strip liquid collecting box 19 is installed at the bottom of the hollow shaft 25, and a plurality of infusion cylinders 23 are equidistantly installed at the bottom of the strip liquid collecting box 19. The bottom of the infusion cylinder 23 extends to the interior of the sedimentation tank 12, and a plurality of drainage holes 22 are equidistantly opened on the side of each infusion cylinder 23. In actual use, the medicine can be transported to the strip liquid collecting box 19 through the infusion pump 5, and discharged into the sedimentation tank 12 through the drainage holes 22 on the infusion cylinder 23. The contact area between the medicine and the sewage in the sedimentation tank 12 is large, and the medicine can fully contact with the sewage.
[0033] It should be noted that if Figure 3 As shown, the outside of the infusion tube 23 is covered with a mesh cover 20, and a fixing ring 21 is installed on the top side of the infusion tube 23. The top of the mesh cover 20 is fastened to the fixing ring 21 by bolts. Under the action of the mesh cover 20, solid impurities in the sewage can be separated to prevent the solid impurities from flowing into the infusion tube 23 and blocking the drainage hole 22.
[0034] like Figure 4 As shown, a first drive motor 7 is installed on the top of the U-shaped frame 8, and a second gear 10 is connected to the end of the output shaft of the first drive motor 7. A first gear 9 is installed on the side of the hollow shaft 25. The first gear 9 is meshed with the second gear 10. The first drive motor 7 is connected to the controller through a wire. In actual use, the first drive motor 7 can drive the hollow shaft 25 to rotate with the cooperation of the first gear 9 and the second gear 10, and then when the medicine is added, the infusion cylinder 23 can rotate in the sedimentation tank 12, so that the medicine can fully contact with the sewage.
[0035] like Figure 5 and Figure 6As shown, a mounting seat 17 is installed on the top of the base 1, and a mounting cavity 29 is opened on the top of the mounting seat 17. A sieve drum 16 is arranged inside the mounting cavity 29. Connecting rings 15 are installed on both sides of the sieve drum 16. The connecting rings 15 are connected to the mounting seat 17 through a rotating mechanism. The rotating mechanism includes two pairs of driving wheels 27 symmetrically installed at both ends of the mounting cavity 29, each pair of driving wheels 27 is located on both sides of the sieve drum 16, and each driving wheel 27 is connected to the side of the connecting ring 15. The end of one of the driving wheels 27 is connected to the output shaft of the second driving motor 28, and the second driving motor 28 is fixed on the side of the mounting seat 17. A drain pipe 14 is installed at the bottom of the sedimentation tank 12, and the end of the drain pipe 14 extends to the inside of the sieve drum 16. The second driving motor 28 is connected to the controller through a wire. In actual use, the precipitated sewage is discharged into the sieve drum 16 through the drain pipe 14. The controller controls the second driving motor 28 to work, so that the sieve drum 16 rotates to filter out the sediment in the sewage, and completes the solid-liquid separation.
[0036] like Figure 1 As shown, a valve 30 is installed on the drain pipe 14 , and the valve 30 can be used to control the opening and closing of the drain pipe 14 . After sedimentation, the drain pipe 14 can be opened through the valve 30 to discharge the sewage from the sedimentation tank 12 .
[0037] It should be noted that if Figure 2 As shown, the screen drum 16 is arranged to be inclined downward, so that the solid impurities filtered by the screen drum 16 will be discharged along the screen drum 16 under the action of gravity, and will not be accumulated in the screen drum 16 and block the screen drum 16.
[0038] like Figure 1 As shown, a water outlet pipe 18 is installed at the bottom end of the side of the mounting seat 17 , and the water filtered by the sieve cylinder 16 flows into the mounting cavity 29 through the sieve cylinder 16 and is discharged along the water outlet pipe 18 .
[0039] Specifically, when the utility model is in use, the controller controls the infusion pump 5 to work, and the infusion pump 5 transports the medicine in the medicine barrel 2 to the strip collecting box 19 through the first infusion tube 3 and the second infusion tube 6, and then the medicine is transported to the infusion cylinder 23 and discharged from the drainage hole 22. At the same time, the controller also controls the first drive motor 7 to work. The first drive motor 7 drives the hollow shaft 25 to rotate under the action of the first gear 9 and the second gear 10, and then drives the infusion cylinder 23 to rotate in the sedimentation tank 12, so that the medicine discharged from the drainage hole 22 can fully contact with the sewage, so that the solid impurities in the sewage are aggregated and precipitated, and the precipitated sewage is discharged into the sieve cylinder 16 through the drainage pipe 14. At the same time, the controller controls the second drive motor 28 to work. The second drive motor 28 drives the sieve cylinder 16 to rotate with the cooperation of the driving wheel 27 and the connecting ring 15, and the solid impurities in the sewage are filtered. The filtered water passes through the sieve cylinder 16 and flows into the installation cavity 29 and is discharged from the outlet pipe 18, and the filtered solid impurities pass through the sieve cylinder 16 and are discharged.
[0040] 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.
