A DRY SOLIDS METERING SYSTEM WITH MEANS FOR SELF-EMPTYING AND QUICK-EMPTYING/CLEANOUT

摘要

A sweep arm assembly (30) and cleanout port (54) are provided for a dry bulk materials feeding system (1). A supply hopper (20) having an outlet (23) is disposed above a chamber (50) such that material may flow from the hopper (20) to the chamber (50). The chamber (50) has a flat bottom surface (51). A feed trough (60) is disposed below a slot (52) in the bottom surface (51) of the chamber (50) such that material may flow from the chamber (50) to the feed trough (60). A sweep arm (33) is disposed in the chamber (50) and located adjacent to the bottom surface (51). The sweep arm (33) is rotated to "sweep" the material in the chamber (50) to the slot (52) in the bottom surface (51).
