DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1-4, An aeration device for treating leachate in a garbage transfer station, comprising an aeration tank 1 and a driving mechanism. One end of the aeration tank 1 is hermetically plugged with a water inlet pipe 2, and the other end of the aeration tank 1 is hermetically plugged with a water outlet pipe 3. A main air pipe 4 is arranged in the aeration tank 1. A plurality of shunt pipes 5 are hermetically plugged on one side of the main air pipe 4. A plurality of aeration cylinders 6 are hermetically plugged at the bottom of the shunt pipe 5. A plurality of air holes 7 are arranged at the bottom end of the aeration cylinder 6. Under the action of an air pump, gas is input from the main air pipe 4 into the shunt pipe 5 and then discharged into the water from the air holes 7 of the aeration cylinder 6, thereby realizing aeration. A connecting rod 10 is slidably plugged at the bottom end of the aeration cylinder 6. A counterweight 11 is welded to the bottom end of the connecting rod 10. The driving mechanism contacts the counterweight 11. An installation disc 8 is welded to the top end of the connecting rod 10. A plurality of dredging rods 9 are welded to the bottom of the installation disc 8. Under the gravity of the counterweight 11, the installation disc 8, the dredging rods 9 and the connecting rod 10 move downward, so that the connecting rod 10 passes through the air hole 7 to dredge it, thereby avoiding impurities from blocking the air hole 7. The dredging rod 9 can pass through the air hole 7.

[0023] The driving mechanism includes two motors 14. The motors 14 are fixed to the outer wall of one end of the aeration tank 1 by bolts. A plurality of rotating rods 12 are rotatably plugged at one end of the aeration tank 1. A plurality of protruding parts are arranged on the rotating rods 12. The protruding parts of the rotating rods 12 contact the counterweight 11. One end between every two rotating rods 12 and the output end of the motor 14 are connected by a synchronous belt through a pulley. A slip ring 15 is sleeved on the protruding part of the rotating rod 12. A plurality of support frames 13 are welded to the inner wall of the bottom of the aeration tank 1. The support frames 13 are sleeved with the shunt pipe 5. A plurality of stirring rods 16 are welded to the outer wall of the rotating rod 12. Driven by the motor 14 and under the transmission action of the synchronous belt, the rotating rod 12 rotates, thereby driving the stirring rod 16 to rotate, so that water and air are fully mixed. The bottom end of the dredging rod 9 is of a conical structure.

[0024] Working principle: When in use, the main air pipe 4 is connected to an air pump. Under the action of the air pump, gas is input from the main air pipe 4 into the shunt pipe 5 and then discharged into the water from the air holes 7 of the aeration cylinder 6, thereby realizing aeration. Then, driven by the motor 14 and under the transmission action of the synchronous belt, the rotating rod 12 rotates, thereby driving the stirring rod 16 to rotate, so that water and air are fully mixed. At the same time, when the rotating rod 12 rotates, the protruding part pushes the counterweight 11, thereby driving the connecting rod 10, the dredging rod 9 and the installation disc 8 to move upward. When the counterweight 11 is separated from the rotating rod 12, under the gravity of the counterweight 11, the installation disc 8, the dredging rod 9 and the connecting rod 10 move downward, so that the connecting rod 10 passes through the air hole 7 to dredge it, thereby avoiding impurities from blocking the air hole 7.
