[0025] Further, the mounting plate 8 is fixedly installed on the top surface of the water inlet pipe 4, the storage tank 6 is fixedly installed on the top surface of the mounting plate 8, the rack 9 is movably installed on the top surface of the mounting plate 8, the two gears 10 are rotatably installed on the top surface of the mounting plate 8, the two gears 10 are simultaneously engaged with the rack 9, the rack 9 can simultaneously drive the two gears 10 to rotate after moving by being engaged with the two gears 10, and the sealing block 13 is coaxially arranged with the gear 10 and fixedly connected thereto, so that the gear 10 can drive the sealing block 13 to rotate.

[0026] Further, the mounting plate 8 is fixedly installed on the top surface of the water inlet pipe 4, the storage tank 6 is fixedly installed on the top surface of the mounting plate 8, the rack 9 is movably installed on the top surface of the mounting plate 8, the two gears 10 are rotatably installed on the top surface of the mounting plate 8, the two gears 10 are simultaneously engaged with the rack 9, the rack 9 can simultaneously drive the two gears 10 to rotate after moving by being engaged with the two gears 10, and the sealing block 13 is coaxially arranged with the gear 10 and fixedly connected thereto, so that the gear 10 can drive the sealing block 13 to rotate.

[0027] In addition, the top surface of the mounting plate 8 and the rack 9 is provided with a through groove 16, the material in the storage tank 6 can fall down through the through groove 16 by setting the through groove 16, the feeding pipe 7 is arranged below the through groove 16, the feeding pipe 7 is fixedly connected on the top surface of the water inlet pipe 4, the storage tank 6 is directly above the feeding pipe 7, the sealing block 13 is between the storage tank 6 and the feeding pipe 7, the two sealing blocks 13 are adhered to the bottom end of the storage tank 6 in the initial state, so that the discharge of the storage tank 6 is limited by the two sealing blocks 13, and the material cannot be easily discharged when the sealing block 13 does not rotate.

[0028] In addition, the side wall of the mounting plate 8 is fixedly provided with a transmission wheel 12, and the pull rope 11 is adhered to the side wall of the transmission wheel 12, so that the pull rope 11 is not easily worn during the pulling process by setting the transmission wheel 12 and the pull rope 11 adhered to the side wall of the transmission wheel 12, thereby prolonging the service life of the pull rope 11.

[0029] It should be noted that the specific size ratio of the main parts such as the rack 9, the gear 10, the rotating plate 17 and the extension spring 14 is not fixed, and can be adjusted according to the actual needs of the user, so that the device can run smoothly.

[0030] In the specific implementation, when treating landfill leachate in a conventional coagulation tank, the staff needs to manually add coagulation and precipitation agent according to experience, and needs to add multiple times during precipitation to better complete the work. In the process, not only human resources are consumed to add coagulation and precipitation agent, but also manual addition of coagulation and precipitation agent is prone to uneven addition in the addition process, affecting the precipitation effect and rate of the sedimentation tank.

[0031] In the present application, the user only needs to put the coagulation and precipitation agent head into the storage tank 6 before using the device, and no additional operation is required. After the coagulation and precipitation agent is added, the subsequent process of sewage entering the sedimentation tank body 1 from the water inlet 2 through the water inlet pipe 4, the sewage will pass through the rotating plate 17, and the impact force will drive the rotating plate 17 to rotate to one side. The rotating plate 17 will pull the pull rope 11 after rotating, and the other end of the pull rope 11 is fixedly connected with the rack 9, so that the rack 9 will be driven to move. The two gears 10 engaged with the rack 9 will slightly rotate due to the movement of the rack 9. The lower part of the gear 10 is fixedly connected with the sealing block 13. After the two gears 10 rotate, the two sealing blocks 13 will also rotate and open from the original position to both sides. At this time, the coagulation and precipitation agent in the storage tank 6 will fall into the feeding pipe 7 from the storage tank 6 and then fall into the water inlet pipe 4 through the feeding pipe 7. The water inlet pipe 4 is the sewage that needs to be mixed with the precipitation agent. Therefore, the sewage will be mixed with the precipitation agent before entering the sedimentation tank body 1. This way can uniformly mix the precipitation agent into the sewage, avoiding uneven addition of the precipitation agent.

[0032] At the same time, the rotation of the rotating plate 17 requires continuous water flow impact, so the precipitator will only fall into the water inlet pipe 4 from the storage tank 6 when the sewage passes through the rotating plate 17, avoiding waste of the precipitator and allowing the precipitator to be automatically added without manual addition.

[0033] By setting the rotating plate 17 and the rack 9, connecting the pull rope 11 between the rotating plate 17 and the mounting plate 8, setting the gear 10 on both sides of the rack 9, and finally fixing and connecting the sealing block 13 below the gear 10, the device can use the impact force generated by the sewage inflow to achieve the effect of automatic addition of the precipitator, and the addition process is completed before the sewage enters the sedimentation tank body 1, so that the precipitator can be uniformly added.

[0034] Working principle: When treating landfill leachate in a conventional coagulation tank, workers need to manually add coagulation and precipitation agents according to experience, and need to add them multiple times during the precipitation period to better complete this work. Not only does this process consume manpower to add coagulation and precipitation agents, but manual addition of coagulation and precipitation agents also easily leads to uneven addition, affecting the precipitation effect and rate of the sedimentation tank.

[0035] In the present application, the user only needs to place the coagulation and precipitation agent head into the storage tank 6 before using the device, and no additional operation is required. After the coagulation and precipitation agent is added, the subsequent process of sewage entering the sedimentation tank body 1 from the water inlet 2 through the water inlet pipe 4, the sewage will pass through the rotating plate 17, and the impact force will drive the rotating plate 17 to rotate to one side. After the rotating plate 17 rotates, it will pull the pull rope 11, and the other end of the pull rope 11 is fixedly connected to the rack 9, so the rack 9 will be driven to move. After the rack 9 moves, the two gears 10 engaged with the rack 9 will slightly rotate due to the movement of the rack 9. The sealing block 13 is fixedly connected below the gear 10, and after the two gears 10 rotate, the two sealing blocks 13 will also rotate and open to the sides from the original position. At this time, the coagulation and precipitation agent in the storage tank 6 will fall into the feeding pipe 7 from the storage tank 6 and then fall into the water inlet pipe 4 through the feeding pipe 7. The water inlet pipe 4 is where the sewage that needs to be mixed with the precipitator is located, so the precipitator will be mixed with the sewage before it enters the sedimentation tank body 1. This way, the precipitator can be uniformly mixed with the sewage, avoiding uneven addition of the precipitator.

[0036] At the same time, the rotation of the rotating plate 17 requires continuous water flow impact, so the precipitator will only fall into the water inlet pipe 4 from the storage tank 6 when the sewage passes through the rotating plate 17, avoiding waste of the precipitator and allowing the precipitator to be automatically added without manual addition.

[0037] By setting the rotating plate 17 and the rack 9, connecting the pull rope 11 between the rotating plate 17 and the mounting plate 8, setting the gear 10 on both sides of the rack 9, and finally setting the sealing block 13 fixedly connected below the gear 10, the device can realize the effect of automatically adding the precipitator by using the impact force generated by the sewage inflow, and the adding process is completed before the sewage enters the sedimentation tank body 1, so that the precipitator can be evenly added.
