The LMC series long-bag spray large-scale bag dust collector adopts negative pressure operation and external filtration. The filter bag is fixed on the flower plate on the upper part of the dust collector through a sealed elastic bag mouth, and a bag cage is installed inside the filter bag Open the filter bag.

During normal operation, the air flow shut-off valve is in the open state, and the dust-laden gas enters the filter chamber under the action of negative pressure, passes through the filter bag, and enters the filter bag after filtering. The clean gas enters the clean air chamber through the outlet of the filter bag. The air flow cut-off valve enters the air outlet flue and is discharged out of the machine; the dust is trapped on the outer surface of the filter bag.

Due to the support of the bag cage, the surface of the filter bag is partially absorbed and collapsed. With the extension of the filtering time, the dust on the outer surface of the filter bag As the thickness increases, the pressure difference between the inside and outside of the filter bag gradually increases. When the pressure difference and the thickness of the dust reach a certain value, the pulse valve on the air bag sequentially injects compressed gas into the filter bag through the injection pipe, and the filter bag changes from a collapsed state to an outer drum instantaneously The deformation of the state makes the dust on the surface of the filter bag clear, fall into the ash hopper, and discharge the dust out of the machine through the ash discharging device.
