ABSTRACT:
A dust collector for cleaning particle-laden air by means of a plurality of filter bags through which the air is passed. The dust collector includes an inlet chamber adapted to receive particle-laden air and an outlet chamber for clean air. The filter bags are supported in the outlet chamber with their lower ends communicating with the inlet chamber and with their upper ends supported by a shaker mechanism adapted to impart at certain selected time intervals a sinusoidal motion to the bags to dislodge accumulations of dust that form therein. The shaker mechanism includes a drive motor and a variable-throw, eccentric crank means. The inlet chamber has means at the bottom thereof for receiving and removing accumulations of dust, including the dust accumulations that are removed from the filter bags. Particle-laden air is introduced into the inlet chamber through a distributor manifold that extends substantially into and across the length of the inlet chamber and which has a plurality of ports formed therein, located and dimensioned to provide a uniform distribution of particle-laden air into the inlet chamber and then to the filter bags.
