Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a solid debris cleaning device for wastewater treatment. Background Technology

[0002] Domestic sewage is wastewater discharged during daily life by residents, mainly originating from residential and public buildings such as homes, government offices, schools, hospitals, shops, public places, and industrial enterprise restrooms. The pollutants contained in domestic sewage are primarily organic matter (such as proteins, carbohydrates, fats, urea, ammonia nitrogen, etc.) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses). Therefore, sewage needs to be treated before being discharged.

[0003] In the process of wastewater treatment, the first step is to remove solid debris from the wastewater. The most common existing method for removing solid debris from wastewater is to use sieves. However, sieves are prone to clogging during this process, requiring frequent and tedious cleaning by staff. Therefore, a solid debris removal device for wastewater treatment is proposed.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a solid debris cleaning device for sewage treatment includes a treatment box 1. A through groove 5 is provided on the side wall of the treatment box 1, and the through groove 5 runs through the treatment box 1. A screen 2 is provided in the through groove 5. The screen 2 is a closed-loop annular structure. A transmission mechanism acting on the screen 2 is provided on the treatment box 1. A collection box 3 is fixedly installed on the outer wall of the treatment box 1 below the screen 2. A cleaning mechanism acting on the screen 2 is provided in the collection box 3. The cleaning mechanism consists of a mounting plate 13 and cleaning brushes 14. The two ends of the mounting plate 13 are fixedly connected to the inner wall of the collection box 3. Multiple cleaning brushes 14 acting on the screen 2 are rotatably installed on the upper end of the mounting plate 13. The multiple cleaning brushes 14 are arranged in a linear array. A driving mechanism is provided at the bottom of the mounting plate 13.

[0021] There are two cleaning agencies, and the two cleaning agencies are located on the same horizontal plane.

[0022] The two cleaning mechanisms can perform double cleaning of the screen 2, ensuring that solid debris on the screen 2 is cleaned more thoroughly.

[0023] The transmission mechanism consists of a transmission chain 6, a transmission shaft 8, a first gear 9, a first fixed plate 10, and a second fixed plate 11. The two sides of the screen 2 are fixedly connected to the transmission chain 6. The inner rings of the two transmission chains 6 are respectively provided with a first gear 9, which meshes with the transmission chain 6. The two first gears 9 located on the same axis are connected by the transmission shaft 8. The two transmission shafts 8 are respectively distributed on both sides of the through groove 5. The two ends of one transmission shaft 8 are rotatably connected to the first fixed plate 10. The two first fixed plates 10 are respectively fixedly connected to the outer wall of the processing box 1. The two ends of the other transmission shaft 8 are rotatably connected to the second fixed plate 11. The two second fixed plates 11 are respectively fixedly connected to the outer wall of the processing box 1. A first motor 12 is fixedly installed on the side wall of the first fixed plate 10. The output shaft of the first motor 12 is fixedly connected to the transmission shaft 8.

[0024] When in use, start motor 12, which drives the transmission shaft 8 to rotate, thereby driving gear 9 to rotate. The rotation of gear 9 will drive the transmission chain 6 to move, thereby driving the screen 2 to move.

[0025] The drive mechanism consists of a second gear 15, a second motor 16, and a third fixing plate 17. Multiple second gears 15 are rotatably mounted on the bottom of the mounting plate 13. The multiple second gears 15 are fixedly connected to multiple cleaning brushes 14 respectively. Adjacent second gears 15 mesh with each other. A second motor 16 is located below one of the second gears 15. The second motor 16 is fixedly connected to the mounting plate 13 through the third fixing plate 17. The output shaft of the second motor 16 is fixedly connected to the second gear 15.

[0026] When in use, starting motor 16 drives gear 15 to rotate, which in turn drives the remaining gear 15 to rotate, which in turn drives multiple cleaning brushes 14 to rotate. The rotation of multiple cleaning brushes 14 can clean solid debris on screen 2 and prevent screen 2 from becoming clogged.

[0027] The upper end of the collection box 3 is fixedly connected to a baffle 7.

[0028] When the cleaning brush 14 cleans the screen 2, the baffle 7 can intercept the splashed waste liquid.

[0030] The guide plate 4 can guide the sewage and prevent it from flowing out of the channel 5.

[0031] This utility model provides a solid debris cleaning device for sewage treatment, the specific working principle of which is as follows:

[0032] In operation, after the wastewater enters the treatment tank 1, the solid debris in the wastewater is screened off by the screen 2. At this time, the first motor 12 is started, driving the transmission shaft 8 to rotate, which in turn drives the first gear 9 to rotate. The rotation of the first gear 9 drives the transmission chain 6 to move, which in turn drives the screen 2 to move. The screen 2 will transfer the solid debris from the inside of the treatment tank 1 to the outside of the treatment tank 1. When the solid debris moves to the end of the screen 2, the solid debris that is not stuck to the screen 2 will fall directly into the collection tank 3. The solid debris stuck to the screen 2 will move to the bottom of the screen 2. At this time, the second motor 16 is started, driving the second gear 15 to rotate, which in turn drives the remaining second gear 15 to rotate, which in turn drives multiple cleaning brushes 14 to rotate. The rotation of multiple cleaning brushes 14 can clean the solid debris on the screen 2 to prevent the screen 2 from becoming clogged. After cleaning, the screen 2 will re-enter the inside of the treatment tank 1.
