Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and specifically, to a wastewater filtering device for sewage treatment. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or for reuse. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people.

[0003] After retrieval, the utility model patent with the publication number of CN218130196U discloses a filtering structure of a sewage treatment device, including a sewage treatment tank, a filter plate penetrating through the left side of the sewage treatment tank. A top box is fixedly connected to the left side of the sewage treatment tank. A motor is fixedly connected to the left side of the inner cavity bottom of the top box. The output end of the motor is fixedly connected to a rotating rod, and the output end of the rotating rod is fixedly connected to a first gear. A rotating rod is horizontally movably connected to the inside of the top box through a bearing, and a second gear is sleeved on the left side of the surface of the rotating rod. This patent achieves the effect of being convenient for disassembly and cleaning. The filtering structure of this sewage treatment device solves the problem that the filter plates of existing sewage treatment devices are mostly fixed inside the device, which is not convenient for disassembly. After a long time of filtration, a lot of impurities will adhere to the filter plates, resulting in a reduction in the subsequent wastewater filtering effect and trouble in cleaning, which greatly limits the filtering efficiency.

[0004] However, the above patent still has the following deficiencies: when there are too many impurities on the filter plate, it is necessary for workers to disassemble the filter plate to clean the impurities on it, and the convenience is poor; secondly, the wastewater cannot be filtered during the cleaning process of the filter plate, which affects the continuity of sewage treatment. Therefore, we propose a wastewater filtering device for sewage treatment. Content of the Utility Model

[0030] In this embodiment, when the sewage is fed, the impurities in the sewage are intercepted by the baffle 6, making the filtering effect better.

[0031] Specifically, please refer to Figure 3 , Figure 6 and Figure 7 . The collection mechanism 22 includes a placement rack 16 fixedly connected to the side of the treatment tank 1. A connection port 9 is opened on the bottom surface of the placement rack 16. A filter box 17 is placed in the inner cavity of the placement rack 16. A plurality of permeation holes 8 are opened on the bottom surface of the filter box 17. A collection box 18 is fixedly sleeved in the inner cavity of the connection port 9. A return pipe 19 is fixedly connected to the bottom surface of the collection box 18. The end of the return pipe 19 extends into the inner cavity of the treatment tank 1.

[0032] In this embodiment, the function of draining the sewage in the impurities is realized through the return pipe 19, so that the sewage filtered from the impurities flows back into the treatment tank 1 again.

[0033] Specifically, please refer to Figure 3 . An electromagnetic valve 20 is fixedly installed on the side of the treatment tank 1. The end of the electromagnetic valve 20 extends into the inner cavity of the treatment tank 1.

[0041] Working principle: When in use, first introduce sewage from the feeding square pipe 15 into the inner cavity of the treatment tank 1. The sewage falls onto the filter belt 5 under the guidance of the guide plate 14. The filter belt 5 is used to filter impurities in the sewage, and the baffle 6 is used to make the impurities accumulate on the filter belt 5. Then start the servo motor 13 to drive the drive shaft 3 to rotate clockwise. The drive shaft 3 drives the filter belt 5 and the first gear 10 to rotate clockwise. The rotation of the filter belt 5 causes the impurities filtered thereon to move to the outside of the treatment tank 1 through the slag outlet 7, and the impurities on the filter belt 5 fall from its upper end into the filter box 17. At this time, other positions on the filter belt 5 continue to filter the sewage. Then, through the meshing transmission between the first gear 10 and the second gear 11, drive the cleaning roller 12 to rotate counterclockwise. The cleaning roller 12 is used to clean the top of the filter belt 5 to make the impurities completely fall. Finally, the impurities in the filter box 17 are left standing, and a small amount of water in the impurities will leak into the collection box 18 through the permeation holes 8. Use the return pipe 19 to transport the water in the collection box 18 back to the treatment tank 1, and that's it.
