[0024] Please see Figures 1-5 The present invention provides a technical solution: a modular domestic sewage treatment device, including a sedimentation tank 1, a temporary storage tank 6 at the top of the sedimentation tank 1, a discharge pipe 8 at the bottom of the temporary storage tank 6, and a movable discharge component on the sedimentation tank 1, the movable discharge component being used to add the medicine inside the temporary storage tank 6 to a random position inside the sedimentation tank 1 through the discharge pipe 8.

[0025] When the above scheme is put into actual use, the wastewater that has undergone preliminary treatment and filtration of garbage is introduced into the sedimentation tank 1. Flocculants and other chemicals are added into the temporary storage tank 6. The chemicals are then introduced into the sedimentation tank 1 through the discharge pipe 8 to react with the wastewater, causing the impurities in the wastewater to flocculate and precipitate, thus further removing them. The discharge pipe 8 is moved within the sedimentation tank 1 by the moving discharge component, so that the chemical solution is added into the discharge pipe 8 at a random location. The solution is then discharged into the sedimentation tank 1 through the discharge pipe 8, allowing the wastewater in the sedimentation tank 1 to fully contact and react with the chemical solution, thereby improving the wastewater treatment effect.

[0026] As a further embodiment of the present invention, the mobile discharge assembly includes a support rod 19. The support rod 19 is fixedly connected to the bottom of the temporary storage tank 6. A rotating seat 21 is rotatably connected to the bottom of the support rod 19. A positioning rod 10 is fixedly connected inside the sedimentation tank 1. The rotating seat 21 is slidably sleeved on the outside of the positioning rod 10. A transmission gear 17 is fixedly connected to the bottom of the support rod 19. A rack plate 9 for meshing with the transmission gear 17 is fixedly connected to the bottom of the sedimentation tank 1. A rotating plate 7 is rotatably sleeved on the support rod 19. A sliding plate 11 is fixedly connected to the bottom of the rotating plate 7. The bottom of the sliding plate 11 is slidably connected to the rack plate 9. A plurality of hoses 18 distributed at equal intervals are fixedly connected to the bottom of the temporary storage tank 6. A threaded pipe 16 is fixedly connected to the bottom of the hoses 18. The bottom of the threaded pipe 16 is connected to the discharge pipe 8. The side wall of the support rod 19... A plurality of transmission racks 13 corresponding to the threaded tube 16 are fixedly connected. A transmission gear 17 is threadedly connected to the threaded tube 16. A fixed cylinder 14 is rotatably sleeved on the outside of the transmission gear 17. The transmission racks 13 mesh with the transmission gears 17. A sliding sleeve 15 is rotatably sleeved on the outside of the fixed cylinder 14. The sliding sleeve 15 is rotatably connected to the rotating plate 7. A connecting spring for resetting the fixed cylinder 14 is fixedly connected to the transmission racks 13. A positioning shaft is slidably connected to the top of the threaded tube 16. The top of the positioning shaft is slidably connected to the bottom of the temporary storage tank 6. A fixed motor is installed inside the temporary storage tank 6. A sealing plate 3 is rotatably connected to the top of the temporary storage tank 6. A connecting rod 2 for slidably connecting with the sealing plate 3 is fixedly connected to the top of the sedimentation tank 1. A connecting plate 5 is fixedly connected to one side of the connecting rod 2. The top of the fixed motor is fixedly connected to the connecting plate 5.

[0027] When the above scheme is put into actual use, when adding chemicals to the sewage inside the sedimentation tank 1, the fixed motor is started to drive the support rod 19 to rotate. The support rod 19 drives the temporary storage tank 6 to rotate together. The fixed gear 12 at the bottom of the support rod 19 meshes with the rack plate 9 as the support rod 19 rotates, causing the support rod 19 to slide along the positioning rod 10. Since the sealing plate 3 is slidably connected to the connecting rod 2, the sealing plate 3 will slide along the connecting rod 2 without rotating. Similarly, the rotating plate 7 under the restriction of the sliding plate 11 will also slide as the support rod 19 rotates. The support rod 19 drives the transmission As rack 13 rotates, the fixed cylinder 14, which is slidably connected to the transmission rack 13, slides accordingly. When the fixed cylinder 14 slides towards the rotating plate 7, the spring on the fixed cylinder 14 is stretched, and the sliding sleeve 15 contacts and rotates with the rotating plate 7. The transmission gear 17 meshes with the transmission rack 13 and rotates. Due to the limiting action of the positioning shaft, the transmission gear 17 can drive the internally threaded pipe 16 to slide up and down, thereby changing the height of the discharge pipe 8. This causes the height of the liquid medicine discharged through the discharge pipe 8 within the sedimentation tank 1 to change accordingly. Furthermore, the discharge pipe 8 rotates together with the support rod 19. This results in changes not only in the horizontal position of the discharge pipe 8 but also in its vertical height. By adding flocculant to the sedimentation tank 1 through multiple sets of discharge pipes 8, the flocculant can fully contact the wastewater inside the sedimentation tank 1 for flocculant formation. During rotation, the support rod 19 rotates at a relatively slow speed, preventing the rotating discharge pipe 8 from significantly breaking up the flocculant sediment and ensuring that the sediment is not damaged by the discharge pipe 8. When the fixed cylinder 14 moves from the protrusion on the rotating plate 7... When sliding inward, the spring's return force pulls the fixed cylinder 14 to slide, causing the transmission gear 17 to mesh and rotate with the transmission rack 13. The discharge pipe 8 can rotate horizontally inside the sedimentation tank 1 and also adjust its height vertically inside the sedimentation tank 1. Moreover, the positions of the multiple sets of discharge pipes 8 are not corresponding, and the height positions of each discharge pipe 8 are different at the same time. In this way, the agent is added to the sedimentation tank 1 through the discharge pipe 8 to react with the sewage flocculation, so that the sewage inside the sedimentation tank 1 can fully contact and react with the agent, thereby improving the sewage treatment effect.

[0028] As a further embodiment of the present invention, the bottom of the rotating seat 21 is rotatably connected to a plurality of pulleys 20 that are equidistantly distributed;

[0029] When the above solution is put into actual use, the bottom of the support rod 19 makes rolling contact with the sedimentation tank 1 through the pulley 20, making it easier for the support rod 19 to slide on the positioning rod 10 and reducing resistance.

[0030] As a further embodiment of the present invention, the top of the sealing plate 3 is provided with a feed inlet 4, and the sealing plate 3 is provided with a sealing gasket for sealing connection with the temporary storage tank 6.

[0031] When the above solution is put into actual use, the flocculation agent required is added into the temporary storage tank 6 through the feed inlet 4. The sealing gasket can effectively prevent leakage at the connection between the sealing plate 3 and the temporary storage tank 6, ensuring the seal.

[0032] As a further embodiment of the present invention, the outer walls of the rotating plate 7 are all chamfered and rounded.

[0033] When the above solution is put into actual use, the sliding sleeve 15 will make more stable contact with the outer wall of the rotating plate 7 when it rotates.

[0034] As a further embodiment of the present invention, the bottom of the discharge pipe 8 is provided with a plurality of discharge ports that are equally spaced.

[0035] When the above scheme is put into actual use, the multiple discharge ports allow the reagent discharged through the discharge pipe 8 to come into full contact with the sewage for flocculation reaction.

[0036] As a further embodiment of the present invention, the inner wall of the rotating seat 21 can be completely fitted with the outer wall of the positioning rod 10;

[0037] When the above solution is put into actual use, the two parts fit together perfectly, making the rotating seat 21 more stable when sliding along the positioning rod 10 and avoiding shaking in other directions.

[0038] Working principle: Wastewater that has undergone preliminary treatment and filtration is introduced into sedimentation tank 1. Flocculants and other chemicals are added to temporary storage tank 6. The chemicals then enter sedimentation tank 1 through discharge pipe 8 to react with the wastewater, causing impurities to flocculate and precipitate, further removing them. When chemicals are added to sedimentation tank 1, a fixed motor is activated, driving support rod 19 to rotate. Support rod 19 drives temporary storage tank 6 to rotate as well. The fixed gear 12 at the bottom of support rod 19 rotates with support rod 19 and meshes with rack plate 9, causing support rod 19 to slide along positioning rod 10. Furthermore, due to the sliding connection between sealing plate 3 and connecting rod 2, the seal is maintained. The sealing plate 3 will slide along the connecting rod 2 without rotating. Similarly, the rotating plate 7, restricted by the sliding plate 11, will slide with the rotation of the support rod 19. The support rod 19 drives the transmission rack 13 to rotate, causing the fixed cylinder 14 slidably connected to the transmission rack 13 to slide along with it. When the fixed cylinder 14 slides towards the rotating plate 7, the spring on the fixed cylinder 14 is stretched, the sliding sleeve 15 contacts and rotates with the rotating plate 7, and the transmission gear 17 meshes and rotates with the transmission rack 13. Due to the limiting effect of the positioning shaft, the transmission gear 17 can drive the internally threaded tube 16 to slide up and down, thereby changing the output. The height of the feed pipe 8 causes the height of the discharged liquid medicine inside the sedimentation tank 1 to change accordingly. Furthermore, the feed pipe 8 rotates together with the support rod 19. This results in changes not only in the horizontal position but also in the vertical height of the feed pipe 8. By adding flocculating liquid medicine into the sedimentation tank 1 through multiple sets of feed pipes 8, the liquid medicine can fully contact the wastewater inside the sedimentation tank 1 for flocculation. During rotation, the support rod 19 rotates at a relatively slow speed, preventing the rotating feed pipe 8 from significantly breaking up the flocculated sediment and ensuring that the flocculated sediment is not disturbed during discharge. When the feed pipe 8 is damaged, and the fixed cylinder 14 slides inward from the protrusion on the rotating plate 7, the spring's return force will pull the fixed cylinder 14 to slide, causing the transmission gear 17 to mesh and rotate with the transmission rack 13. The discharge pipe 8 can rotate horizontally inside the sedimentation tank 1 and can also adjust its height vertically inside the sedimentation tank 1. Moreover, the positions of the multiple sets of discharge pipes 8 are not corresponding, and the height positions of each discharge pipe 8 are different at the same time. In this way, the agent is added to the sedimentation tank 1 through the discharge pipe 8 to react with the sewage flocculation, so that the sewage inside the sedimentation tank 1 can fully contact and react with the agent, thereby improving the sewage treatment effect.
