[0026] Working principle: When using this device, install the equipment rack 1 on the top of the sewage treatment equipment, with the transfer hopper 9 facing the water storage part of the sewage treatment equipment. Add the pharmaceutical powder into Figure 2 the storage hopper 2 therein. Zero the precision electronic balance 5, and control the servo motor 3 to drive the feeding auger rod 4 to rotate stably and unidirectionally. The rotation of the feeding auger rod 4 conveys the powder in the storage hopper 2 downward into the collection box 7. When the reading of the precision electronic balance 5 reaches the measurement requirement, immediately control the servo motor 3 to stop working. The servo motor 3 locks the feeding auger rod 4, and the threads on the surface of the feeding auger rod 4 block the tubular structure at the bottom end of the storage hopper 2, preventing the powder from falling.

[0027] Subsequently, rotate the symmetrically distributed positioning bolts 12 in Figure 3 away from the collection box 7, no longer squeezing the top of the outer side of the collection box 7 to fix the baffle 10. Pull out the baffle 10 upward, and simultaneously control the electric telescopic rod 8 to extend. The electric telescopic rod 8 rotates and pushes Figure 2 the collection box 7 in

[0028] to rotate and tilt counterclockwise around the support shaft 6 with the transfer hopper 9, pour the measured powder into the sewage stored in the sewage treatment equipment, then control the electric telescopic rod 8 to shorten and reset, drive the collection box 7 to rotate and reset to the horizontal, install the baffle 10 back in place and rotate the positioning bolts 12 to squeeze the top of the outer side of the collection box 7, and then the precise metering, feeding and conveying operation can be carried out again according to the steps described above. This is the working principle of the precise metering, feeding and conveying equipment for the powder. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
