[0017] See also Figures 1-3, the present utility model provides a technical solution: including a sewage tank 1 and a chemical agent tank 5. On both sides of the upper end of the sewage tank 1, mounting frames 2 are fixed. Between the mounting frames 2, a track plate 3 is fixed. On the upper end of the track plate 3, a sliding plate 4 is slidably connected. The chemical agent tank 5 is fixed on the upper end of the sliding plate 4. On the side wall of the upper end of the chemical agent tank 5, an injection pipe 6 is fixed, and a liquid extraction pump 61 is installed on the injection pipe 6. On the track plate 3, a driving assembly for driving the sliding plate 4 to move is provided. At the bottom of the chemical agent tank 5, a pair of water outlet pipes 51 are fixed. The bottom of the water outlet pipes 51 is located inside the sewage tank 1. On both sides of the water outlet pipes 51 at the bottom of the chemical agent tank 5, a pair of air pipes 53 are fixed. The bottom of the air pipes 53 is located inside the sewage tank 1. On the upper end of the chemical agent tank 5, a sealing cover 55 is fixed, and a liquid level sensor 57 is fixed at the bottom of the sealing cover 55. On the side wall of the part of the water outlet pipe 51 located inside the sewage tank 1, water outlet openings 52 are equidistantly arranged. On the side wall of the part of the air pipe 53 located inside the sewage tank 1, aeration openings 54 are equidistantly arranged. On the track plate 3, a pair of limiting grooves 33 are opened. At the bottom of the sliding plate 4 and at the position corresponding to the limiting grooves 33, limiting blocks 42 are fixed. Both the air pipe 53 and the water outlet pipe 51 pass through the limiting blocks 42. The upper end of the air pipe 53 passes through the bottom of the chemical agent tank 5 and extends into the chemical agent tank 5. The bottom of the water outlet pipe 51 is fixed to the bottom of the chemical agent tank 5. Solenoid valves are installed on both the water outlet pipe 51 and the injection pipe 6. On the upper end of the sealing cover 55, an air inflation pump 56 is fixed.
[0018] The driving assembly includes a driving groove 31 and a driving block 41. The driving groove 31 is opened at the central position of the track plate 3. The driving block 41 is slidably connected in the driving groove 31, and the upper end is fixed at the central position of the bottom of the sliding plate 4. In the driving groove 31, a reciprocating lead screw 32 is rotatably connected. The reciprocating lead screw 32 passes through the driving block 41 and is threadedly connected to the driving block 41. At the position on the side wall of the track plate 3 aligned with the reciprocating lead screw 32, a driving motor 34 is fixed. The output end of the driving motor 34 is fixed to the end of the reciprocating lead screw 32.
[0019] Working principle: First, connect the entire device to an external power supply. Driven by the liquid extraction pump 61, the chemical agent is pumped into the chemical agent tank 5 through the injection pipe 6. At this time, keep the solenoid valve of the injection pipe 6 open and the solenoid valve of the water outlet pipe 51 closed. At the same time, use the liquid level sensor 57 to monitor the liquid level height of the pumped chemical agent. After its height reaches the predetermined value, the injection can be stopped, and the solenoid valve of the injection pipe 6 can be closed. At the same time, open the solenoid valve of the water outlet pipe 51. At this time, the chemical agent will enter the sewage tank 1 through the water outlet pipe 51. Then, driven by the driving motor 34, drive the reciprocating lead screw 32 to rotate, so that the driving block 41 reciprocally slides in the driving groove 31, and then drive the sliding plate 4 and the chemical agent tank 5 to reciprocally slide, and finally the chemical agent can be injected into different positions of the sewage tank 1. During this process, the air inflation pump 56 can also be used to inflate the chemical agent tank 5, so that the chemical agent can flow out more stably from the water outlet openings 52. At the same time, the gas will also enter the air pipe 53 and finally spray out from the aeration openings 54 to stir the sewage and increase the liquid fluidity to achieve the purpose of rapid mixing.
