Technical Field

[0001] The utility model relates to the technical field of domestic sewage treatment, in particular to a domestic sewage purification treatment device. Background Art

[0002] Domestic sewage is wastewater discharged from daily life, primarily from residential and public buildings, such as residences, government offices, schools, hospitals, shops, public places, and industrial restrooms. The pollutants contained in domestic sewage are primarily organic matter and a large number of pathogenic microorganisms. The organic matter in domestic sewage is extremely unstable and easily decomposes, producing foul odors. Bacteria and pathogens thrive on organic matter in domestic sewage, which can lead to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] When purifying domestic sewage, it is necessary to pour the sewage into a sedimentation tank and add drugs into the sedimentation tank to allow the sewage and drugs to precipitate so that the organic matter, microorganisms and other substances in the sewage can be precipitated in the sedimentation tank. However, a large amount of sediment is deposited at the bottom of the sedimentation tank. If it cannot be discharged in time, it is easy to cause the sediment to be discharged together with the water in the upper layer, affecting the purification effect of domestic sewage.

[0022] 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 the embodiments.

[0023] Reference Figure 1-Figure 4 A domestic sewage purification treatment device includes a sedimentation tank 1. A guide seat 2 with an inclined top surface is installed at the bottom of the sedimentation tank 1, and the guide seat 2 corresponds to the bottom surface of the sedimentation tank 1. When in use, sewage is placed in the sedimentation tank 1 and medicine is added. At this time, at least one third drive motor 15 is provided above the sedimentation tank 1. The third drive motor 15 is installed on a mounting frame 14, and the end of the mounting frame 14 is fixed to the side of the sedimentation tank 1. A stirring shaft 16 is installed at the bottom of the third drive motor 15. The stirring shaft 16 is placed in the sedimentation tank 1, and a plurality of stirring blades 17 arranged at intervals are installed on the stirring shaft 16. When the third drive motor 15 starts to operate, it drives the stirring blades 17 to stir the sewage, thereby accelerating the mixing of the sewage and the medicine and allowing the organic matter and microorganisms in the sewage to precipitate faster.

[0024] Furthermore, the end of the mounting bracket 14 is detachably connected to the side of the sedimentation tank 1 through a fastener. In actual use, the fastener is a bolt or a screw, which facilitates the disassembly and assembly of the mounting bracket 14 on the sedimentation tank 1.

[0025] As organic matter, microorganisms and other substances in the sewage precipitate, the top surface of the guide seat 2 is a smooth surface, and an arc-shaped groove 3 is provided at the bottom of the guide seat 2. The sediment will flow along the guide seat 2 into the arc-shaped groove 3 and fall into the arc-shaped groove 3, and a first spiral conveying shaft 4 is provided in the end of the arc-shaped groove 3, and one end of the first spiral conveying shaft 4 passes through the sedimentation tank 1 and is connected to a first drive motor 6, the first drive motor 6 is fixed to the outer wall of the sedimentation tank 1, and the first spiral conveying shaft 4 is rotatably connected to the sedimentation tank 1, and the other end of the first spiral conveying shaft 4 is rotatably installed on the support frame 5, and the support frame 5 is fixed to the inner wall of the arc-shaped groove 3. When the stirring shaft 16 rotates, the first spiral conveying shaft 4 will also rotate under the operation of the first drive motor 6, so that the sediment falling into the arc-shaped groove 3 can be gathered to the middle of the arc-shaped groove 3;

[0026] There is a gap between the two first spiral conveying shafts 4 that are relatively close to one end, and a cylinder 8 is provided above the gap. The cylinder 8 is fixed to the inner wall of the sedimentation tank 1 through a fixing frame 11, and there is a gap between the bottom of the cylinder 8 and the arc groove 3, and a second spiral conveying shaft 7 is coaxially provided in the cylinder 8. The bottom of the second spiral conveying shaft 7 is rotatably installed in the arc groove 3, and the top of the second spiral conveying shaft 7 passes through the cylinder 8 and is connected to a second drive motor 9. The second drive motor 9 is fixed on the cylinder 8, and the second spiral conveying shaft 7 is rotatably connected to the top of the cylinder 8, and a sewage pipe 10 is installed on the top side of the cylinder 8. At this time, the sediment gathered in the middle of the arc groove 3 will be transported upward under the rotation of the second spiral conveying shaft 7, so that the sediment is transported upward in the cylinder 8 and discharged outward to the outside of the sedimentation tank 1 through the sewage pipe 10.

[0027] Specifically, in actual use, the sewage pipe 10 extends outside the sedimentation tank 1 and bends outward to the bottom of the sedimentation tank 1. A collection container such as a collection box can be set at the bottom of the sewage pipe 10 to collect the sediment discharged from the sedimentation tank 1, and the sediment will not splash when it falls into the collection container due to the height of the sewage pipe 10 being too high from the ground.

[0028] It should be noted that an outlet pipe 12 is provided on one side of the sedimentation tank 1. The outlet pipe 12 is detachably installed with the sedimentation tank 1 through a connecting frame 13. Finally, the treated sewage can be discharged outward from the outlet pipe 12. During actual use, the outlet pipe 12 is set away from the cylinder 8, and the bottom of the outlet pipe 12 is located above the top of the guide seat 2, reducing the contact between the sediment and the outlet pipe 12, ensuring that the sediment will not be discharged along with the water at the outlet pipe 12.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
