Multi-station non-stop feeding screw pump system

Abstract

The utility model discloses a kind of multi-station non-stop feeding screw pump systems, including base, several storage devices and feeding device. Main passage and multiple branch passages are equipped in base, each storage device is communicated with main passage by branch passage, and feeding device is connected with main passage. Storage device includes storage barrel, valve part and pressurizing part, and valve part is controlled on-off by rotary switch valve, realizes raw material switching between multiple stations. Feeding device adopts screw pump structure, and material is conveyed by motor-driven rotating rod rotation. The utility model can realize different feeding, without shutdown when replenishing raw material, improve production efficiency, reduce raw material waste and equipment loss, and be applicable to the continuous supply of viscous material in chemical industry.
