Technical Field
[0001] This utility model belongs to the field of sedimentation tower technology, specifically relating to a rapid sedimentation tower for papermaking wastewater treatment. Background Technology
[0002] Waste paper has become one of the major sources of pollution in people's lives. Recycling waste paper into new paper and turning waste into treasure can greatly reduce environmental pollution. However, material conversion can easily generate secondary pollution. Papermaking wastewater is a type of industrial wastewater that is difficult to treat. How to scientifically and rationally treat papermaking wastewater, recover water resources and fibers, turn waste into treasure, and generate good economic benefits has always been a topic of research for experts at home and abroad. In the process of wastewater treatment, a structure that uses sedimentation to remove pollutants from the water is called a sedimentation tower.
[0003] However, existing sedimentation towers often lack the function of cleaning the inner wall of the sedimentation tower. When using existing sedimentation towers, the sediment will settle at the bottom of the sedimentation tower. After opening the valve, most of the sediment will fall directly through the drain pipe, but the inner wall of the sedimentation tower will still be covered with a thick layer of sediment that is difficult to clean. Moreover, the sediment can easily cause blockage of the drain pipe when it is discharged, which increases the difficulty of cleaning. Therefore, there is an urgent need for a rapid sedimentation tower for papermaking wastewater treatment to solve the above problems. Utility Model Content
[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a rapid sedimentation tower for papermaking wastewater treatment, so as to solve the problems mentioned in the background art that existing sedimentation towers often do not have the function of cleaning the inner wall of the sedimentation tower, and the sediments are prone to causing blockage of the sewage pipe when being discharged, which increases the difficulty of cleaning.

The scraping structure 3 can scrape off the sediment attached to the inner wall of the sedimentation tower body 1, preventing the sediment from adhering to the inner wall of the sedimentation tower body 1 and making it difficult to clean. The anti-clogging structure 4 can transport the sediment, preventing the sediment from clogging the sewage pipe 14, causing inconvenience during use, and improving the discharge efficiency.
[0023] Furthermore, a water inlet pipe 11 is fixedly connected to the bottom right end of the sedimentation tower body 1, a water outlet pipe 12 is fixedly connected to the top right end of the sedimentation tower body 1, and support legs 13 are fixedly connected to the four corners of the bottom of the sedimentation tower body 1. Wastewater is transported into the sedimentation tower body 1 through the water inlet pipe 11. After the wastewater enters the sedimentation tower body 1, it slowly rises and is discharged through the water outlet pipe 12. The support legs 13 support the sedimentation tower body 1.
[0024] Furthermore, both motor 22 and motor 31 are fixedly connected to the outer wall of the sedimentation tower body 1 by four fixing bolts. Both motor 22 and motor 31 are connected to an external power source and are electrically connected to a control console. The external power source provides power to motor 22 and motor 31, and the control console sends control signals to realize the functions of starting, stopping, speed adjustment, and rotation direction of motor 22 and motor 31.
[0025] Furthermore, rotating sealing rings 35 are fixedly connected to both the upper and lower ends of the rotating ring 34.

[0029] Working Principle: During operation, wastewater is fed into the sedimentation tower body 1 through the inlet pipe 11. The wastewater slowly rises after entering the sedimentation tower body 1, overflowing from the bottom and passing through the filter plate 21. The filter plate 21 filters out large particles such as fibers in the water, while fine fibers and sludge concentrate at the bottom of the sedimentation tower body 1. Motor 1 22 is activated, causing it to rotate the adsorption disc 23 and adsorption stack 24. The adsorption stack 24 adsorbs pollutants in the water flowing through the filter plate 21. After being reabsorbed by the adsorption stack 24, the wastewater is discharged above the adsorption disc 23 and discharged through the outlet pipe 12. When cleaning the bottom inner wall of the sedimentation tower body 1 is required, motor 2 31 is activated, causing it to rotate the bevel gear 1 32, which in turn rotates the bevel gear 2 33, which in turn rotates the rotating ring 34. The rotating ring 34 drives the scraper 36 to rotate, which scrapes away the sediment attached to the inner wall of the sedimentation tower body 1. The scraping structure 3 can scrape away the sediment attached to the inner wall of the sedimentation tower body 1, preventing the sediment from adhering to the inner wall of the sedimentation tower body 1 and making it difficult to clean, thus improving practicality. When it is necessary to discharge the sediment, the solenoid valve of the drain pipe 14 is opened. When the scraper 36 rotates, the scraper 36 drives the rotating rod 42 at the bottom to rotate. The position of the rotating rod 42 is limited by the bracket 41, which improves the stability of the rotating rod 42 when rotating. The rotating rod 42 drives the spiral blade 43 to rotate, and the spiral blade 43 transports the sediment in the drain pipe 14, preventing the sediment from clogging the drain pipe 14. The anti-clogging structure 4 can transport the sediment, preventing the sediment from clogging the drain pipe 14 and causing inconvenience during use, and improving the discharge efficiency.
