Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a sedimentation tank for water pollution treatment. Background Technology

[0002] Sedimentation tanks are widely used in various wastewater treatment scenarios. Their principle is to rely on gravity to allow impurities in the water to settle naturally, thereby purifying the water. In this process, flocculants and other agents can be added to accelerate the sedimentation efficiency.

[0003] Depending on the stage of wastewater treatment, the function of sedimentation tanks varies. For example, sedimentation tanks for preliminary sedimentation are mainly used to purify large particulate suspended impurities. They are usually equipped with filters to enhance solid-liquid separation, and the flow rate inside the tank is relatively fast. Sedimentation tanks for secondary sedimentation are mainly used to treat activated sludge mixed liquor. They are characterized by light weight and slow settling speed, requiring more time to settle, and the flow rate inside the tank is relatively slow.

[0004] In order to ensure the filtration effect of the filter screen in the primary sedimentation tank, it is necessary to clean it regularly. However, cleaning often requires disassembling and removing the screen for manual cleaning. This method not only involves high labor intensity for workers, but also requires the suspension of use of the primary sedimentation tank, which affects the efficiency of sewage treatment. Utility Model Content

[0030] See Figure 1-4 A sedimentation tank for water pollution treatment, comprising:

[0031] The pool body 1 is elongated and is divided into a sedimentation tank 11 and a washing tank 12 by a partition wall 2. One end of the sedimentation tank 11 is connected to an inlet pipe 13 and the other end is connected to a drain pipe 15. An inlet valve 14 is installed on the inlet pipe 13 to control the inlet water volume, and a drain valve 16 is installed on the drain pipe 15 to control the drain volume.

[0032] A filter mechanism 4 is also installed inside the sedimentation tank 1, near the drain pipe 15. This filter mechanism 4 filters out large particles of impurities in the sedimentation tank 11, ensuring effective wastewater treatment. The filter mechanism 4 includes a motor 42 and a filter belt 43. (See attached image.) Figure 3 , 4 A bracket 41 is fixedly installed on the pool body 1. Several rollers 7 are rotatably installed inside the pool body 1 and at the bracket 41. The rollers 7 tension the filter belt 43, making the filter belt 43 have a herringbone structure. One side of the filter belt 43 is located in the sedimentation tank 11 for filtering impurities, and the other side is located in the cleaning tank 12 for easy cleaning of the filter holes. One of the rollers 7 is connected to a motor 42, so that the motor 42 can drive the filter belt 43 to rotate. Furthermore, a first pulley 44 is fixedly connected to the side of the roller 7 connected to the motor 42.

[0033] Further, see Figure 3 The filter belt 43 is inclined on one side of the sedimentation tank 11, which increases the contact area between the filter belt 43 and the water in the sedimentation tank 11, thereby improving the filtration efficiency. The belt on one side of the cleaning tank 12 is vertically arranged, which facilitates cleaning while reducing the area occupied.

[0034] The cleaning tank 12 is also equipped with a cleaning mechanism 5 and a backwashing mechanism 6 corresponding to the filter belt 43.

[0035] During operation, the filter belt 43 blocks large particles of impurities in the sedimentation tank 11. As usage time increases, a large amount of impurities accumulate on the filter belt 43, easily causing clogging of the filter pores and affecting filtration efficiency. At this point, the motor 42 is started, driving the filter belt 43 to rotate, allowing the dirty section to enter the cleaning tank 12 for cleaning. The clean filter belt 43 then enters the sedimentation tank 11 for filtration, eliminating the need to interrupt the use of the sedimentation tank 11 and ensuring wastewater treatment efficiency. Furthermore, the motor 42 can be connected to a central control system for timed start and stop, thereby achieving automatic cleaning of the filter belt 43.

[0036] In some embodiments, the cleaning mechanism 5 includes a support 51, a drive shaft 52, a second pulley 53, a third pulley 54, a roller 55, and brush bristles 56. The support 51 is fixedly installed on the edge of the pool body 1, and the drive shaft 52 is rotatably connected to the support 51. One end of the drive shaft 52 is fixedly connected to the second pulley 53, and the second pulley 53 is connected to the first pulley 44 via belt drive. The other end of the drive shaft 52 is fixedly connected to the third pulley 54. The roller 55 is rotatably installed inside the cleaning pool 12. The roller 55 is provided with brush bristles 56 corresponding to the filter belt 43, and the roller 55 is connected to the third pulley 54 via belt drive. When the motor 42 starts, it drives the first pulley 44 to rotate, which drives the drive shaft 52 to rotate via belt drive, and finally drives the roller 55 to rotate, so that the brush bristles 56 on the roller 55 can wash the filter belt 43. It should be noted that... Figure 3 The filter belt 43 rotates counterclockwise, and at the same time the drum 55 also rotates counterclockwise.

[0037] In some embodiments, the backwashing mechanism 6 includes a pipe 61 and nozzles 62. One end of the pipe 61 extends into the cleaning tank 12, and nozzles 62 corresponding to the filter belt 43 are evenly arranged on it. The other end of the pipe 61 is connected to an external air supply device. One side of the cleaning tank 12 is connected to a clean water pipe 17, and the other side is connected to a drain pipe 18. Valves are provided on both the clean water pipe 17 and the drain pipe 18. In use, clean water is first injected into the cleaning tank 12 through the clean water pipe 17. After the brush bristles 56 are used to preliminarily wash the deposits on the filter belt 43, compressed air is sprayed out through the nozzles 62 to backwash the filter holes and ensure that the filter holes are unobstructed. When the water in the cleaning tank 12 is relatively turbid, the drain pipe 18 is opened to discharge the sewage, and then clean water is injected again.

[0038] Based on the above embodiment, baffles 3 are installed alternately on the side of the sedimentation tank 11 near the water inlet pipe 13, and the orientation of the baffles 3 is perpendicular to the axis of the water inlet pipe 13, thereby increasing the length of water flow and reducing the water flow velocity in the sedimentation tank 11, which facilitates the settling of impurities.

[0039] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
