The utility model belongs to the field of feeding equipment, and particularly relates to a high-precision metering and feeding device for chemical
reagent production, which comprises a frame, supporting seats are fixedly mounted on the inner walls of two sides of the frame, weighing machines are mounted at the tops of the supporting seats, fixing plates are mounted at the tops of the weighing machines, and a same weighing box is fixedly mounted between the two fixing plates. A discharging hole is formed in the inner wall of the bottom of the weighing box, a feeding
pipe is installed at the bottom of the weighing box, a transverse plate is fixedly installed at the top of the weighing box, a rotating
pipe is rotatably installed on the transverse plate, a spiral pushing plate is installed on the rotating
pipe, and two rotating shafts are rotatably installed on the inner wall of the front side and the inner wall of the rear side of the feeding pipe. The automatic feeding device is reasonable in design, raw materials in the weighing box can be weighed in a high-precision mode through the weighing device, and the feeding precision, stability and
automation degree of chemical
reagent production are greatly improved through
raw material pushing, precise opening and closing of the discharging hole and feeding amount control.
