[0034] In order to facilitate the addition of medicines, a feeding component 3 is provided, which includes a storage box 31. A support frame 33 is fixed to one side of the bottom of the storage box 31. The bottom of the support frame 33 is fixed to one side of the top of the box body 1.

[0035] Working principle: Through the action of gravity, the sludge pool can settle the solid particles and floating matter in the sewage, thereby purifying the water quality. The settled sludge is transported to the inner side of the mud injection pipe 4 through the conveyor, so that the sludge is transported to the inside of the mixing tank 7. When transporting the sludge, the baffle 34 is pulled to one side, so that the baffle 34 slides on the inner side of the chute 36, and at the same time, the first discharge hole 35 on one side of the baffle 34 is located on the side of the second discharge hole 37, so that the medicine inside the storage box 31 passes through the second discharge hole 37 and the first discharge hole 35 and falls to the inside of the mixing tank 7, so that the medicine can evenly enter the inside of the mixing tank 7 and be fully mixed with the sludge;

[0036] When the sludge enters the mixing tank 7, the switch is pressed to control the output shaft of the motor 21 to rotate, and the output shaft drives the input shaft of the gear reducer 22 to rotate, and the output shaft of the gear reducer 22 drives the first rotating shaft 24 to rotate, and at the same time, the first rotating shaft 24 drives multiple stirring blades 210 to rotate inside the mixing tank 7, and stirs and mixes the sludge and the reagent entering the mixing tank 7.

At the same time, the stirring blade 210 rotates in the opposite direction to the stirring tank 7, so that the agent and the sludge are mixed evenly. Through the cooperation of the conveying system stirring component 2 and the feeding component 3, the agent can fall evenly into the stirring tank 7, avoiding local accumulation or loss of the agent. The stirring blade 210 rotates in the opposite direction to the stirring tank 7, which further enhances the uniformity of mixing and ensures sufficient contact and reaction between the sludge and the agent.

[0037] When it is not necessary to add medicine, it is only necessary to push the baffle 34 so that one side of the limit block 32 is attached to one side of the support frame 33. At this time, the first discharge hole 35 is not in communication with the second discharge hole 37, thereby preventing the addition of medicine.
