Mechanical Shaker Bag Filter

Relies on the eccentric excitation of the shaker motor to drive the entire filter bag support framework in a reciprocating rocking motion, without the use of compressed air. Dust-laden gas enters the housing, and dust is trapped on the inner surface of the filter bags (predominantly internal filtration). When the operating resistance increases to the set value, the fan is stopped (off-line cleaning), the shaker motor is activated, and dust falls by inertia into the lower ash hopper. After cleaning is complete, the fan restarts to resume filtration.

Advantages: No compressed air system required; no need for an air source, convenient on-site use; simple control using only a time relay or differential pressure switch; dust collection efficiency can reach over 99%.
Disadvantages: No compartmentalized design; cleaning must be performed off-line, i.e., cannot perform continuous on-line cleaning; suitable only for intermittent operation. Filter bags are subject to repetitive rocking fatigue, leading to relatively rapid bag wear. Connecting rods and oscillating shafts are prone to wear and require regular maintenance.

Silo top, bin top, belt conveyor transfer points, small standalone local dust extraction; not suitable for large systems requiring continuous non-stop operation.
