The utility model discloses an automatic monitoring diaphragm metering dosing device, which relates to the technical field of
environmental protection devices and comprises a bottom plate, a
sewage barrel for storing
sewage to be treated is arranged at the upper end of the bottom plate, a fixing frame is arranged in the middle of the upper end of the bottom plate, and a
diaphragm pump for conveying medicaments is mounted at the upper end of the fixing frame. The output end of the
diaphragm pump communicates with the interior of the
sewage barrel through a first flow guide
pipe, a rotating seat reciprocates in the vertical direction and drives a stirring roller to rotate, chemicals in the chemical conveying
barrel are fully mixed, the
reaction speed of the chemicals is increased, a scraping ring scrapes away the residual chemicals on the surface of the inner wall of the chemical conveying barrel, and the
utilization rate of the chemicals is increased; the upper end of the sensing seat is fixedly connected with the output end of the air pressure rod, the lower end of the sensing seat is rotationally connected with the rotating seat, the sensing seat pushes the rotating seat to move, and the sensing seat is rotationally connected with the rotating seat, so that rotating conditions are provided for rotation of the rotating seat in
linear motion, the stirring range is enlarged, and the
drug reaction is accelerated.
