Technical Field

[0001] This utility model relates to the field of rainwater and sewage treatment technology, and in particular to a secondary separation device for rainwater and sewage. Background Technology

[0002] With the increasing scarcity of water resources, water recycling is receiving more and more attention. Natural rainwater, with its advantages of low hardness and low pollutant content, is becoming increasingly important in reducing urban stormwater damage and developing water sources. For example, rainwater from rooftops and ground surfaces in residential areas and building complexes, after collection and treatment, can be used for landscaping, greening, car washes, road cleaning, cooling water replenishment, toilet flushing, and other non-domestic uses. It can also be used for crop irrigation and groundwater management.

[0003] Currently, solid-liquid separation is typically required in rainwater and sewage treatment processes. However, existing technologies generally employ simple separation mechanisms, which easily lead to many unseparated impurities flowing into the next process, resulting in poor separation efficiency and failing to meet current application requirements. Therefore, this invention provides a secondary rainwater and sewage separation device. Utility Model Content

[0007] The secondary separation box is equipped with a third drive roller and a fourth drive roller, which are rotatably installed inside. A secondary separation mesh belt is connected between the third drive roller and the fourth drive roller. A second rotating shaft is fixedly sleeved on the third drive roller, and one end of the second rotating shaft extends rotatably to the outside of the secondary separation box and is fixedly sleeved with a second drive wheel. A double-groove sprocket is connected to the second drive wheel through a second chain belt.

[0014] This utility model provides a secondary separation device for rainwater and sewage. Through the separation work of the primary separation mesh belt, solid impurities in sewage can be initially separated. Subsequently, the secondary separation mesh belt can further separate the previously unseparated solid impurities in the sewage, thereby improving the separation effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A secondary separation device for rainwater and sewage includes a primary separation tank 1 and a secondary separation tank 2 located below the primary separation tank 1. The bottom of the primary separation tank 1 is connected to the secondary separation tank 2 via a conduit 13. A first transmission roller 9 and a second transmission roller 11 located to the right of the first transmission roller 9 are rotatably installed inside the primary separation tank 1, and a primary separation mesh belt 10 is connected between the first transmission roller 9 and the second transmission roller 11. A first rotating shaft 8 is fixedly sleeved on the first transmission roller 9, and one end of the first rotating shaft 8 extends rotatably to the outside of the primary separation tank 1 and is fixedly sleeved with a first transmission wheel 7. A support frame 3 is fixedly connected to the left side of the primary separation tank 1, and a motor 4 is fixedly installed on the left side of the support frame 3 via a mounting bracket. A double-groove sprocket 5 is fixedly sleeved at the output end of the motor 4, and the double-groove sprocket 5 is connected to the first transmission wheel 7 via a first chain belt 6. A first opening 102 is provided at the right end of the primary separation tank 1 located to the right of the second transmission roller 11, and a first garbage collection frame 12 is fixedly sleeved inside the first opening 102.

[0021] The secondary separation box 2 is rotatably installed with a third transmission roller 19 and a fourth transmission roller 20, and a secondary separation mesh belt 14 is connected between the third transmission roller 19 and the fourth transmission roller 20. A second rotating shaft 18 is fixedly sleeved on the third transmission roller 19, and one end of the second rotating shaft 18 extends rotatably to the outside of the secondary separation box 2 and is fixedly sleeved with a second transmission wheel 17. The double groove sprocket 5 is connected to the second transmission wheel 17 through a second chain belt 16. A second opening 21 is provided at the right end of the secondary separation box 2, and a second garbage collection frame 15 is fitted inside the second opening 21.

[0022] In this example, the top of the primary separation tank 1 is provided with a water inlet 101; the bottom of the secondary separation tank 2 is provided with a drain pipe.

[0023] In this example, the primary separation mesh belt 10 and the secondary separation mesh belt 14 are respectively provided with separation mesh holes, and the size of the separation mesh holes on the primary separation mesh belt 10 is larger than the size of the separation mesh holes on the secondary separation mesh belt 14.

[0024] In this example, the first garbage collection frame 12 and the second garbage collection frame 15 have the same overall structure. The left end of the first garbage collection frame 12 extends to the lower right side of the primary separation mesh belt 10, and a filter mesh 120 is provided on the left inner wall of the second transmission roller 11. A water filter basket 121 is also fixedly connected to the bottom left end of the first garbage collection frame 12.

[0025] In this example, the double-groove sprocket 5 is provided with two chain drive grooves 501, and the two chain drive grooves 501 are respectively adapted to the first chain belt 6 and the second chain belt 16.

[0026] In this example, both the first transmission roller 9 and the second transmission roller 11 are provided with transmission teeth, and the first transmission roller 9 and the second transmission roller 11 are respectively engaged with the primary separation mesh belt 10 through the transmission teeth.

[0027] Working principle: During operation, rainwater and sewage enter the primary separation tank 1 through the inlet 101, and are simultaneously separated and filtered through the separation mesh on the primary separation belt 10. This separates solid impurities from the water and leaves them on the primary separation belt 10. At the same time, the motor 5 drives the double-groove sprocket 5 to rotate clockwise, which in turn drives the first transmission wheel 7 via the first chain belt 6, thereby causing the first transmission wheel 7 and the first rotating shaft 8 to rotate simultaneously. The first rotating shaft 8 then drives the first transmission roller 9 to rotate, which in turn drives the primary separation belt 10 and the second transmission roller 11. This process transports the impurities separated on the primary separation belt 10 to the right... The waste is collected in the first waste collection box 12 on the lower side; the liquid water after separation and filtration by the primary separation mesh belt 10 flows into the secondary separation box 2 through the conduit 13. At this time, the solid debris in the water that was not separated before can be further separated by the secondary separation mesh belt 14. Similarly, when the double groove sprocket 5 rotates clockwise, it is also driven by the second chain belt 16, the second transmission wheel 17, the second rotating shaft 18, and the third transmission roller 19, which in turn drives the secondary separation mesh belt 14 to rotate clockwise, and the solid debris separated on the secondary separation mesh belt 14 is collected through the second waste collection box 15. Finally, the separated water is discharged through the drain pipe.

[0028] In summary, the rainwater and sewage secondary separation device provided by this utility model can initially separate solid impurities in sewage through the separation work of the primary separation mesh belt 10, and then further separate the previously unseparated solid impurities through the secondary separation mesh belt 14, thereby improving the separation effect and avoiding the disadvantages of the previous technology where a lot of unseparated impurities flowed into the next process due to the use of a single separation mechanism. At the same time, it can also quickly collect the separated solid impurities, and the structure is simple and easy for people to use.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
