[0025] Example 1, please refer to Figures 1-7, this embodiment provides a dual-stage activated carbon advanced sewage treatment device, including: a box body 1; a water inlet pipe 2, which is fixedly connected to the outer wall of the box body 1; a chemical dosing assembly 3, which is arranged on the surface and inside of the box body 1. The arrangement of the chemical dosing assembly 3 on the surface and inside of the box body 1 is responsible for adding treatment chemicals to the sewage. These chemicals may include flocculants, coagulants or other chemical substances, aiming to promote the precipitation or degradation of suspended solids, oils and other pollutants in the sewage; a sewage treatment structure 4, which is arranged inside the box body 1 and is used for the preliminary filtration and treatment of sewage; an exhaust pipeline 51 is fixedly connected to the inner wall of the box body 1, and an air outlet 52 is opened at the upper end of the box body 1. The exhaust pipeline 51 is responsible for guiding the gases or odors generated during sewage treatment to the outside. The air outlet 52 is the outlet of the exhaust pipeline 51 and is used to discharge the exhaust gas or volatile gases to the external environment. Protective frames 53 are fixedly connected to both sides of the exhaust pipeline 51. Installation grooves 54, through grooves 55 and slag discharge ports 517 are arranged inside the exhaust pipeline 51. An activated carbon plate A 56 is arranged inside the through groove 55, and an activated carbon plate B 57 is arranged inside one of the protective frames 53. Two baffles 58 are slidably connected inside each installation groove 54, and a spring 59 is fixedly connected between the two baffles 58. A motor 514 is fixedly connected to the outer wall of the box body 1, and a transmission shaft 515 is fixedly connected to the output end of the motor 514. A push rod 516 is fixedly connected to the outer wall of the transmission shaft 515. A hydraulic transmission part for pushing the activated carbon plate A 56 and the activated carbon plate B 57 is arranged on the side of the protective frame 53. The function of the hydraulic transmission part is to provide precise control force through the hydraulic system, enabling the activated carbon plate to be pushed, pulled, exchanged and cleaned at different working stages. The hydraulic transmission part includes a hydraulic chamber 510, which is fixedly connected to the outer wall of the box body 1. A hydraulic rod A 511 and a hydraulic rod B 512 are slidably connected inside both ends of the hydraulic chamber 510. One end of the hydraulic rod A 511 far away from the hydraulic chamber 510 slidably penetrates through the protective frame 53, and a movable plate 513 is fixedly sleeved on the outer wall of the hydraulic rod B 512. Limiting grooves 518 are opened on the sides of the activated carbon plate A 56 and the activated carbon plate B 57, and limiting blocks 519 are fixedly connected to the inner wall of the exhaust pipeline 51. The limiting blocks 519 are slidably connected with the limiting grooves 518. The functions of the limiting blocks 519 and the limiting grooves 518 are to ensure the stability of the movement of the activated carbon plate. A knocking assembly 6 is assembled outside the hydraulic rod A 511, and an ash cleaning assembly 7 is assembled at the bottom of the exhaust pipeline 51.

[0026] In use, sewage enters the interior of the sewage treatment tank in the box body 1 through the water inlet pipe 2, and is controlled by the control system in the equipment room. The sewage treatment structure 4 in the sewage pretreatment tank is used to preliminarily treat and filter the sewage, so that larger particulate suspensions in the sewage are removed. The dosing assembly 3 adds treatment agents to the sewage, reacts with the sewage, degrades the wastewater, and filters the odor generated by volatilization through the activated carbon plate A56 and discharges it from the air outlet 52. When the activated carbon plate A56 is saturated with adsorption, the motor 514 is started, which drives the push rod 516 to rotate towards the activated carbon plate B57 side through the transmission shaft 515. Then, the push rod 516 will contact the movable plate 513 on this side and push the movable plate 513 towards the side of the box body 1. As a result, the hydraulic rod B512 fixedly connected to the movable plate 513 will move into the interior of the hydraulic chamber 510. Then, the hydraulic rod A511 at the other end of the hydraulic chamber 510 on this side will move outwards and push the activated carbon plate B57 inside the protective frame 53 towards the exhaust pipe 51. When the activated carbon plate B57 moves, it will first contact the baffle 58. Since the side surface of the baffle 58 is set as an inclined surface, after the activated carbon plate B57 contacts it and continues to move, it will squeeze the upper and lower baffles 58 to move upwards and downwards until the baffle 58 contacts the upper and lower surfaces of the activated carbon plate B57. At this time, it continues to move a certain distance inside the through groove 55, and the activated carbon plate B57 will contact the side surface of the activated carbon plate A56. Then, the activated carbon plate B57 will push the activated carbon plate A56 to move, and the other side of the activated carbon plate A56 will push the baffle 58 on the other side upwards. When the baffle 58 completely contacts the upper and lower surfaces of the activated carbon plate A56, at this time, when the activated carbon plate B57 is continuously pushed, the activated carbon plate A56 will enter the interior of the other protective frame 53 through the through groove 55 and squeeze the hydraulic rod A511 inside the protective frame 53 to move into the interior of the hydraulic chamber 510. Then, the hydraulic rod B512 inside the hydraulic chamber 510 on this side will drive the movable plate 513 outside it to move towards the middle of the box body 1, so that the push rod 516 can contact the movable plate 513 on this side when rotating, so as to replace the cleaned activated carbon plate A56 with the activated carbon plate B57. At the same time, since the end of the baffle 58 close to the activated carbon plate is set as an inclined surface, when the activated carbon plate moves, the baffle 58 can clean and scrape the bottom surface of the activated carbon plate, and the scraped impurities will fall out from the slag outlet 517. At the same time, when the activated carbon plate moves, it will be slidably connected to the outside of the limit block 519 of the exhaust pipe 51 through the limit groove 518 on the side surface, thereby ensuring the stability during sliding. The spring 59 can ensure that the baffle 58 is closed when not affected by force, and can ensure that the baffle 58 always contacts the activated carbon plate when it moves.

[0027] Embodiment 2. Please refer to Figures 1-7, on the basis of Embodiment 1, the knocking component 6 includes a connecting plate 61. The connecting plate 61 is fixedly sleeved on the outer wall of the hydraulic rod A511. The other end of the connecting plate 61 is fixedly connected with a toothed plate 62. The upper end of the toothed plate 62 meshes with a gear 63. The gear 63 is rotatably connected to the inner wall of the box body 1 through a rotating shaft. A rotating rod 64 is rotatably connected to the inner wall of the box body 1. An knocking rod 65 is fixedly sleeved on the outer part of the rotating rod 64. An knocking ball 66 is fixedly connected to the outer wall of the knocking rod 65. A curved rod 67 is fixedly connected to the outer wall of the rotating rod 64. Two knocking rods 65 and knocking balls 66 are fixedly sleeved on the outer wall of each rotating rod 64 and are symmetrically arranged.

[0028] During use, when the hydraulic rod B512 moves, it will drive the connecting plate 61 to move. Then, the toothed plate 62 at the other end of the connecting plate 61 will move accordingly. Furthermore, the engaged gear 63 will rotate accordingly. Since both ends of the curved rod 67 are located between the teeth of the gear 63, when the gear 63 rotates, both ends of the curved rod 67 will alternately contact the teeth of the gear 63. Furthermore, the curved rod 67 will swing left and right, and then drive the rotating rod 64 to swing. Then, the knocking rod 65 will also swing accordingly, and then drive the knocking ball 66 to knock on the exhaust pipe 51, thereby avoiding impurities remaining inside the slag outlet 517 and enabling the impurities to fall smoothly into the ash transporting frame 71.

[0029] [[ID=⑥]]Embodiment 3, please refer to Figures 1-9 , on the basis of Embodiment 1, the ash cleaning component 7 includes an ash transporting frame 71. The ash transporting frame 71 is fixedly connected to the bottom of the exhaust pipe 51. One end of the rotating rod 64 penetrates through the box body 1 and is fixedly connected with a rotating column 72. A guiding groove 73 is formed on the outer wall of the rotating column 72. A sliding rod 74 is slidably connected inside the guiding groove 73. The upper end of the sliding rod 74 is fixedly connected with a connecting rod 75. The other end of the connecting rod 75 is fixedly connected with an ash cleaning plate 76. The upper end of the ash transporting frame 71 is provided with a slag inlet corresponding to the slag outlet 517. The ash cleaning plate 76 is slidably connected inside the ash transporting frame 71.

[0030] During use, when the rotating rod 64 rotates, it will drive the rotating column 72 to rotate. Then, the guiding groove 73 formed on the outer wall of the rotating column 72 will also rotate accordingly. Furthermore, the sliding rod 74 slidably connected inside the guiding groove 73 will move back and forth along the opening direction of the guiding groove 73, and then drive the ash cleaning plate 76 to reciprocate inside the ash transporting frame 71 through the connecting rod 75. Furthermore, the ash cleaning plate 76 can discharge the dust and impurities inside the ash transporting frame 71.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
