Dust separating and carrier returning device

摘要

Disclosed is a dust separating and carrier returning device, which comprises: an outer raw material transfer passage (1) and an inner carrier returning passage (2), and a sieve cage (4) with one end thereof connected with the raw material transfer passage (1) and the other end sealed; a spiral conveyer belt is provided between the sieve cage (4) and the carrier returning passage (2), with the two sides thereof connected to the inner wall of the sieve cage (4) and the outer wall of the carrier returning passage (2); and the end of the spiral conveyer belt is connected to the rear port of the carrier returning passage (2) via a guide plate (5). The above device achieves the dedusting of the carrier during the transmission process and the returning of the dedusted carrier to another working circle, thereby improving work efficiency and reducing the number of manufacturing process steps which in turn reduces the process cost.
