[0026] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0027] Please refer to Figures 1-6, the utility model provides a technical solution: a sewage pretreatment device for municipal water supply and drainage design, including a treatment tank 1. A slideway 3 is opened at the top of the treatment tank 1. A moving block 4 is slidably connected inside the slideway 3. A motor 6 is fixedly installed on one side of the treatment tank 1. A threaded rod 2 is installed at the output end of the motor 6. The surface of the threaded rod 2 is threadedly connected with the inside of the moving block 4. The bottom of the moving block 4 is fixedly connected with a moving box 10. A first connecting pipe 11 is fixedly installed at the bottom of the moving box 10. A drain pipe 12 communicated with the inside of the first connecting pipe 11 is fixedly installed at the bottom of the first connecting pipe 11. A medicine liquid tank 7 is fixedly installed at the top of the treatment tank 1. A metering container 8 communicated with the inside of the medicine liquid tank 7 is fixedly installed at the bottom of the medicine liquid tank 7. A second connecting pipe 20 communicated with the inside of the medicine liquid tank 7 is fixedly installed at the lower end of the metering container 8. One end of the second connecting pipe 20 slidably penetrates through the treatment tank 1 and extends to the inside of the treatment tank 1. The other end of the second connecting pipe 20 is connected with the first connecting pipe 11.

[0028] Add the prepared sewage treatment medicine into the inside of the medicine liquid tank 7. When it enters, the medicine will enter into the inside of the metering container 8, enter into the inside of the first connecting pipe 11 through the second connecting pipe 20, and be discharged through the drain pipe 12. Start the motor 6 to drive the threaded rod 2 to rotate, thereby driving the moving block 4 to slide inside the slideway 3, thereby moving the drain pipe 12, which is convenient for adding sewage treatment medicine into the inside of the treatment tank 1 and facilitating the pretreatment of sewage.

[0029] An extrusion frame 5 is fixedly installed at the top of the moving block 4. A sliding rod 16 is slidably connected inside the metering container 8. A sealing plate 21 is fixedly installed at the upper end of the sliding rod 16. A tension spring 22 is sleeved on the sliding rod 16. The upper end of the tension spring 22 is fixedly connected with the sealing plate 21. The lower end of the tension spring 22 is fixedly connected with the metering container 8.

[0030] When the moving block 4 moves, it will drive the extrusion frame 5 to move, so that the protruding part on the extrusion frame 5 no longer presses the sliding rod 16, thereby enabling the sealing plate 21 to reset under the tension of the tension spring 22, thereby enabling the sealing plate 21 to enter into the inside of the metering container 8, so that the medicine liquid inside the medicine liquid tank 7 no longer enters into the inside of the metering container 8. Furthermore, under the action of the tension of the tension spring 22, the medicine liquid inside the metering container 8 is squeezed into the inside of the second connecting pipe 20 and then discharged, which is convenient for quantitatively conveying the medicine liquid to the first connecting pipe 11. When the motor 6 rotates in the reverse direction, the moving block 4 will move in the reverse direction, thereby causing the inclined surface of the extrusion frame 5 to press the sliding rod 16, so that the sliding rod 16 slides into the inside of the metering container 8, thereby stretching the tension spring 22 and moving the sealing plate 21 upward, allowing the medicine liquid inside the medicine liquid tank 7 to enter into the inside of the metering container 8, completing the quantitative addition of the medicine liquid into the inside of the metering container 8.

[0031] One side of the extrusion frame 5 is fixedly installed with a toothed plate 18. A rotating shaft 17 is rotatably connected inside the metering container 8. A driving gear 19 is fixedly installed at the lower end of the rotating shaft 17. The driving gear 19 is meshed with the toothed plate 18. One end of the rotating shaft 17 extending into the metering container 8 is fixedly installed with a rotating sealing plate 23. The rotating sealing plate 23 is located at the connection between the second connecting pipe 20 and the metering container 8.

[0032] When the extrusion frame 5 moves, the toothed plate 18 will move along with the extrusion frame 5, thereby driving the driving gear 19 and the rotating shaft 17 to rotate, so that the rotating sealing plate 23 no longer seals the connection between the second connecting pipe 20 and the metering container 8. Then the liquid medicine inside the metering container 8 enters the inside of the second connecting pipe 20. When the extrusion frame 5 resets, the rotating shaft 17 will rotate in the reverse direction, thereby sealing the connection between the second connecting pipe 20 and the metering container 8, preventing the liquid medicine inside the metering container 8 from entering the inside of the second connecting pipe 20. This facilitates the quantitative addition of liquid medicine into the metering container 8, and at the same time facilitates preventing the liquid medicine inside the metering container 8 from being discharged into the second connecting pipe 20 when adding liquid medicine into the metering container 8.

[0033] A plurality of rotating shafts 14 are rotatably connected inside the moving box 10 and the first connecting pipe 11. A large gear 25 is fixedly sleeved on each of the plurality of rotating shafts 14. The plurality of large gears 25 are meshed with each other. A small gear 24 is fixedly sleeved on one of the rotating shafts 14. A rack 9 is fixedly installed on the inner wall of the treatment box 1. The rack 9 is slidably connected inside the moving box 10. The rack 9 is meshed with the small gear 24. A dispersion blade 13 is fixedly installed on the rotating shaft 14.

[0034] When the first connecting pipe 11 and the moving box 10 move, the rack 9 will drive the small gear 24 and the rotating shaft 14 to rotate. Then, through the plurality of large gears 25, the plurality of rotating shafts 14 are driven to rotate, so that the plurality of dispersion blades 13 rotate, facilitating the dispersion of the liquid medicine discharged from the drain pipe 12, and facilitating the dispersion of the liquid medicine inside the treatment box 1, facilitating the pretreatment of the sewage, and improving the full contact between the liquid medicine and the sewage.

[0035] A stirring blade 15 is fixedly installed on the rotating shaft 14.

[0036] The rotating shaft 14 moves along with the first connecting pipe 11 and the moving box 10, and at the same time rotates self - sufficiently, thereby realizing the stirring of the sewage inside the treatment box 1, realizing the full mixing of the liquid medicine and the sewage, improving the mixing effect, and further improving the treatment effect of the sewage.

[0037] Working principle:

[0038] It is added to the inside of the liquid medicine tank 7. When it enters, the medicine will enter the inside of the metering container 8, enter the inside of the first connecting pipe 11 through the second connecting pipe 20, and be discharged through the drain pipe 12. Start the motor 6 to drive the threaded rod 2 to rotate by the motor 6, and then drive the moving block 4 to slide inside the slideway 3, so that the drain pipe 12 moves, which is convenient for adding sewage treatment medicine into the treatment tank 1. The moving block 4 drives the extrusion frame 5 to move, so that the protruding part on the extrusion frame 5 no longer extrudes the sliding rod 16. Then the sealing plate 21 is reset by the pulling force of the tension spring 22, and the sealing plate 21 enters the inside of the metering container 8, so that the liquid medicine inside the liquid medicine tank 7 no longer enters the inside of the metering container 8. Then, under the action of the pulling force of the tension spring 22, the liquid medicine inside the metering container 8 is extruded into the inside of the second connecting pipe 20 and then discharged, which is convenient for quantitatively conveying the liquid medicine to the first connecting pipe 11. When the motor 6 rotates in the reverse direction, the moving block 4 will move in the reverse direction, and then the inclined surface of the extrusion frame 5 will extrude the sliding rod 16, so that the sliding rod 16 slides into the inside of the metering container 8, stretching the tension spring 22, moving the sealing plate 21 upward, and allowing the liquid medicine inside the liquid medicine tank 7 to enter the inside of the metering container 8, completing the quantitative addition of the liquid medicine into the inside of the metering container 8.

[0039] When the first connecting pipe 11 and the moving box 10 move, the rack 9 will drive the pinion 24 and the rotating shaft 14 to rotate. Then, through a plurality of large gears 25, a plurality of rotating shafts 14 are driven to rotate, and a plurality of dispersing blades 13 rotate, which is convenient for dispersing the liquid medicine discharged from the drain pipe 12.

[0040] 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 for some of the technical features.
