[0002] As a key link in the sewage treatment process, the sedimentation tank is mainly used to remove suspended solids and some organic matter in the sewage. It uses the principle of gravity separation to make the heavier particles in the sewage (such as sand, sludge, etc.) sink to the bottom of the water, while the lighter substances float to the surface, thereby achieving the purpose of purifying the water quality. Sedimentation tank equipment is widely used in the treatment of domestic sewage, industrial wastewater, aquaculture wastewater, etc. The spraying equipment is an auxiliary equipment in the sewage treatment process. It is used to add chemical substances such as coagulants and deodorants to the water to help remove pollutants in the water or improve water quality. It can effectively improve the sewage treatment effect of the sedimentation tank.

[0003] In the prior art, a Chinese patent with document number CN108609707A discloses a mobile drug spreading device for a sedimentation tank for domestic sewage treatment, including a sedimentation tank, a top plate, a servo motor, a first bearing seat, a screw, a nut, a fixing rod, a sleeve, a mounting plate, a drug spreading box, a sieve, a connecting plate, etc.; a top plate is provided above the sedimentation tank, and a servo motor is connected to the bottom right side of the top plate.

[0004] Although the mobile spraying equipment of the above patent can effectively and evenly mix the powder with domestic sewage by adding powder while moving, and prevents the powder from settling at the bottom of the sedimentation tank by continuously rotating the first stirring rod during the movement, it still cannot solve some problems existing in the existing spraying equipment: (1) When a large amount of liquid medicine is contained in the spraying box and the medicine is added while moving, the spraying mechanism will continue to exert pressure on moving parts such as the screw rod and the motor, and may cause excessive pressure and damage the mobile equipment; (2) In order to enhance the spraying effect, the excessive pursuit of device integration further increases the load on the moving parts and reduces the service life of the equipment. At the same time, excessive device integration leads to increased maintenance time and labor costs, and may increase the difficulty of subsequent equipment improvement and upgrading.
