Title: Dust separator for air from grain purifier - recycles air through cyclone and discharges air through filter
Inventor: AUFFARTH HORST
IPC: B01D50/00
Filed: 1977-10-28
Abstract: A dust remover for the air extracted from a grain purifier comprises a flow divider for the extracted air, from which one branch passes to a filter while the other branch passes to a cyclone separator; the discharge from the cyclone returns to the air inlet openings of the grain purifier. Pref. the air flow divider is a forked branch in a pipe, with a pivoting flap valve. The filter is pref. a jet filter. The air entering the grain purifier is composed of a mixt. of fresh air and air recycled from the cyclone separator. During operation, the air passing through the separator and the filter becomes steadily more heavily loaded with dust and thus the separating efficiency of these two items increases. At the same time, the only air discharged to atmos. is that from the filter, thus enabling a high standard of discharge to be maintained.
