Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to an interception device for wastewater treatment. Background Technology

[0002] The application of interception devices in wastewater treatment stems from the increasingly severe water pollution problem and the urgent need for sustainable development. With rapid industrialization and urbanization, the amount of suspended solids, grease, plastics, and other impurities in domestic sewage, industrial wastewater, and agricultural runoff has increased significantly. Direct discharge would clog pipe networks, disrupt the ecological balance, and exacerbate water scarcity. Traditional treatment processes struggle to efficiently separate pollutants of different particle sizes. Interception devices (such as bar screens, sieves, and membrane modules) effectively remove solid waste during the pretreatment stage through physical interception, reducing the load on subsequent biological treatment and ensuring the stable operation of the wastewater treatment system. Their application not only meets environmental regulations for emission standards but also provides the foundation for reclaimed water reuse and resource utilization, playing a crucial role in improving the water environment and promoting a circular economy.

[0003] Currently, there are still some challenges in intercepting large pollutants such as plastic film and cloth strips in sewage treatment. These flexible debris are easy to get tangled in the bar screen or screen, causing equipment blockage. Manual cleaning is inefficient and increases maintenance frequency and operating costs. Utility Model Content

A sleeve 9 is fixedly connected to the outer wall of the sleeve 9. A brush 10 is fixedly connected to the outer wall of the sleeve 9. A filter assembly is provided inside the wastewater tank 1.

[0027] Specifically, the sewage tank 1 fixes the base 2, the supporting steel frame 3, and the motor 4. The motor 4 rotates through the rotating wheel 5 and the transmission belt 6, which in turn drives the transmission wheel 29 to rotate. The sewage tank 1 provides a rotatable space for the first round rod 7. The transmission wheel 29 drives the first round rod 7 to rotate. The first connecting slot 11 provides a sliding space for the connecting block 12. The second connecting slot 15 provides a retractable space for the connecting block 12. The connecting block 12 connects the first round rod 7 and the second round rod 8 to rotate together. The second round rod 8 fixes the spring 16 and allows the connecting block 12 to return to its initial position after sliding. The round rod slot 14 provides a sliding space for the third round rod 13. The second round rod 8 fixes the sleeve 9. The sleeve 9 fixes the brush 10 and drives the brush 10 to rotate and intercept long strip-shaped pollutants. The sewage tank 1 fixes the filter assembly.

[0028] Reference Figure 2 The filter assembly includes a limiting block 17, the outer wall of which is fixedly connected to the inner wall of the sewage tank 1, and an intercepting net 18 is slidably connected inside the limiting block 17.

[0029] Specifically, the sewage tank 1 serves to fix the limiting block 17, the limiting block 17 serves to limit the interception net 18, and the interception net 18 is used to intercept pollutants.

[0030] Reference Figure 1 , Figure 2 and Figure 5 A supporting steel frame 3 is fixedly connected to the outer wall of the sewage tank 1. A cylinder 21 is rotatably connected inside the supporting steel frame 3. A rotating handle 19 is fixedly connected to the outer wall of the cylinder 21. A bevel gear 20 is fixedly connected to the outer wall of the rotating handle 19. The outer wall of a cylindrical rod 13 is slidably connected to the inner wall of a cylindrical rod groove 14. A bevel gear 22 is meshed with the tooth end of the bevel gear 20. A threaded rod 23 is fixedly connected inside the bevel gear 22. A square steel block 25 is rotatably connected to the outer wall of the threaded rod 23. The outer wall of the square steel block 25 is fixedly connected to the outer wall of the sewage tank 1. A hole-punching block 24 is threadedly connected to the outer wall of the threaded rod 23. An L-shaped steel frame 26 is fixedly connected to the outer wall of the hole-punching block 24. A connecting rod 27 is fixedly connected to the outer wall of the L-shaped steel frame 26. A collection box 28 is fixedly connected to the outer wall of the connecting rod 27. The outer wall of the collection box 28 is connected to the inside of the sewage tank 1.

[0031] Specifically, the supporting steel frame 3 provides space for the cylinder 21 to rotate. The cylinder 21, the rotating handle 19, and the bevel gear 20 are fixedly connected as a whole. The rotation of the rotating handle 19 drives the three to rotate together. The rotation of the bevel gear 20 drives the rotation of the bevel gear 22. The rotation of the threaded rod 23 causes the hole-digging block 24 to move upward. The hole-digging block 24, the L-shaped steel frame 26, the connecting rod 27, and the collection box 28 are fixedly connected as a whole. The movement of the hole-digging block 24 drives the collection box 28 to move upward.

[0032] Working principle: Wastewater flows through the inlet pipe into the wastewater tank 1 and passes through the interceptor screen 18 to filter impurities. During the filtration process, the motor 4 is started to rotate the rotating wheel 5, which in turn drives the transmission wheel 29 through the transmission belt 6, forcing the first round rod 7 to rotate as well. The connecting block 12 connects the first round rod 7 and the second round rod 8, causing the second round rod 8 to rotate, which in turn drives the brush 10 on the second round rod 8 to rotate. This achieves the effect of intercepting large pollutants such as plastic film and cloth strips in the wastewater, which helps to improve the overall efficiency of wastewater treatment, while extending the service life of the filter screen and ensuring the stable operation of the wastewater treatment system.

[0033] After the sewage has been treated for a period of time, manually pull the round rod 13 to compress the connecting block 12 and move the spring 16 backward, allowing it to slide out from the connecting slot 11. This allows the round rod 8 to be removed from the sewage tank 1, achieving the effect of detachable cleaning of the brush 10. This helps to balance the functionality and maintenance convenience of the sewage treatment device and reduces long-term costs.

[0034] After the sewage has been treated for a period of time, manually turn the rotating handle 19. The threaded rod 23 will rotate through the bevel gear 1 20 and bevel gear 22, forcing the hole block 24 to move upward on the threaded rod 23. This will drive the L-shaped steel frame 26 and the collection box 28 to move upward through the connecting rod 27, thus achieving the effect of conveniently cleaning the pollutants trapped by the interception net 18. This will help reduce manual maintenance time and improve the sustainability of the system.
