Description

Technical Field

[0001] The utility model relates to the technical field of rack-type terminal boxes, in particular to a sewage treatment dosing device. Background Art

[0002] Utility model patent CN220723618U discloses a sewage treatment dosing device, comprising a base, a support block is installed on one side of the top of the base, a mixing barrel is arranged on the top of the base, a sliding fixing mechanism of the mixing barrel is arranged on the top of the base, a stirring rod is arranged inside the mixing barrel, a brush handle is installed on the surface of the bottom end of the stirring rod and the brush handle is connected to the bottom end of the mixing barrel, a first pulley is fixedly installed on the top of the stirring rod, a motor is mounted on the top of the support block, a second pulley is fixedly installed on the output shaft of the motor, and a belt is connected between the second pulley and the first pulley.
