[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a sewage treatment device.

[0032] like Figure 1 、 Figure 2 and Figure 3 The sewage treatment device includes a filter box 1, which is an L-shaped box. The vertical section of the filter box 1 is separated by a preliminary filter pool 11. The vertical section of the filter box 1 is rotatably connected to the inner wall side of the horizontal section of the filter box 1. The two rotating shafts 2 are fastened with sealing rings 21. The sealing rings 21 are located in the side walls of the filter box 1. The two rotating shafts 2 are fixed with adjusting gears 3. The adjusting gears 3 are fan-shaped gears. The two adjusting gears 3 are meshed with each other. The two adjusting gears 3 are respectively connected to connecting rod assemblies 4. The two sets of connecting rod assemblies 4 are connected to the filter box 1. The two sets of connecting rod assemblies 4 are commonly connected to a support frame 5. A filter grille 51 is installed on the support frame 5. The support frame 5 is located in the preliminary filter pool 11 and is slidably connected to the filter box 1. The two sets of connecting rod assemblies 4 are respectively connected to the cover plates 6, and the two cover plates 6 jointly close the top of the preliminary filter tank 11 (that is, the top opening of the vertical section of the filter box 1). The adjusting gear 3 is used to control the two cover plates 6 to move synchronously relative to each other. When the two cover plates 6 move away from each other until the top of the preliminary filter tank 11 is fully opened, the connecting rod assembly 4 drives the support frame 5 and the filter grille 51 to rise to the top of the preliminary filter tank 11.

[0033] The filter housing 1 is further divided into a regulating tank 12, a sedimentation tank 13, and a biological reactor 14. A stirring rod 15 is rotatably installed in the regulating tank 12 and driven by a motor 16. The motor 16 is mounted on the top of the horizontal section of the filter housing 1. The bottom of the sedimentation tank 13 is connected to a sludge discharge pipe 17. A guide ramp 18 is installed in the sedimentation tank 13 and tilts downward toward the sludge discharge pipe 17. The water inlet of the filter housing 1 is connected to the preliminary filter tank 11, which is connected to the sedimentation tank 13, which is connected to the biological reactor 14, which is connected to the water outlet of the filter housing 1. A ladder 19 is mounted on one side of the horizontal section of the filter housing 1.

[0034] Integrating adjustment, sedimentation and biological treatment into the same box reduces the connecting pipes and floor space between different equipment, reduces engineering complexity and operating costs. When the primary filter tank 11 is performing normal filtering work, the cover 6 can close the filter tank to reduce the entry of external pollutants and avoid overflow or odor diffusion. When the filter grille 51 needs to be replaced, it is only necessary to manually push open the two cover plates 6. Under the action of the connecting rod assembly 4, the support frame 5 and the filter grille 51 can be lifted to the top of the primary filter tank 11. Workers can directly stand on the filter box 1 to remove debris on the filter grille 51. After cleaning, the cover plate 6 can be pushed back, which facilitates daily cleaning and maintenance. It can be quickly replaced and cleaned without complex lifting equipment, reducing the difficulty of later maintenance.

[0035] like Figure 2 , the cover plate 6 is a concave plate, the cover plate 6 is buckled on the top of the filter box 1, the connecting rod assembly 4 includes a first connecting rod 41, a second connecting rod 42, a third connecting rod 43 and a fourth connecting rod 44, one end of the first connecting rod 41 is hinged to the side of the cover plate 6 away from the horizontal section of the filter box 1, the other end of the first connecting rod 41 is hinged to the outer wall of the filter box 1 away from its horizontal section, one end of the second connecting rod 42 is hinged to the side of the cover plate 6 away from the horizontal section of the filter box 1, the other end of the second connecting rod 42 is fixed to the end of the rotating shaft 2 extending out of the filter box 1, and the first connecting rod 41 and the second connecting rod 42 are parallel to each other;

[0036] One end of the third connecting rod 43 is fixed to the rotating shaft 2. The third connecting rod 43 is located inside the filter box 1. One end of the fourth connecting rod 44 is hinged to the third connecting rod 43. The other end of the fourth connecting rod 44 is hinged to the support frame 5. When the cover plate 6 closes the top of the preliminary filter tank 11, the hinge point between the third connecting rod 43 and the support frame 5 is farther away from the middle of the filter grille 51 than the hinge point between the third connecting rod 43 and the fourth connecting rod 44. A counterweight plate 61 is installed on both cover plates 6, and both cover plates 6 are connected to a push rod 62. Limit plates 110 are set on the top of the front and rear sides of the filter box 1. When the filter grille 51 is lifted to the opening of the preliminary filter tank 11, the cover plate 6 is supported on the limit plates 110 on the same side.

[0037] When the push rod 62 passes over the rotating shaft 2, the cover 6 can automatically fall under the action of the gravity of the counterweight plate 61, making it convenient for maintenance personnel to open and close the preliminary filter tank 11. In addition, when the cover 6 is pushed open, the first connecting rod 41 and the second connecting rod 42 rotate synchronously, and the second connecting rod 42 drives the rotating shaft 2 to rotate, thereby rotating the third connecting rod 43 and the fourth connecting rod 44, thereby realizing the upward lifting of the support frame 5 and the filter grille 51, and realizing precise control of the movement of the cover 6 and the filter grille 51.

[0038] The implementation principle of the embodiment of the present application is: when the primary filter tank 11 is performing normal filtering work, the cover 6 can close the filter tank, reduce the entry of external pollutants, and avoid overflow or odor diffusion. When the filter grille 51 needs to be replaced, it is only necessary to manually push open the two cover plates 6. Under the action of the connecting rod assembly 4, the support frame 5 and the filter grille 51 can be lifted to the top of the primary filter tank 11. Workers can directly stand on the filter box 1 to remove debris on the filter grille 51. After cleaning, the cover plate 6 can be pushed back, which facilitates daily cleaning and maintenance. It can be quickly replaced and cleaned without complex lifting equipment, reducing the difficulty of later maintenance.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
