Description

Fly ash unloading device for bag filter

technical field

The utility model relates to a fly ash unloading device for a bag dust collector, which belongs to the technical field of bag dust collectors.

Background technique

Inside the shell of the bag filter, there is a cloth bag for filtering dust. The bag divides the shell into two independent spaces. There is an air inlet on one side of the bag, and an exhaust port on the other side. The air with dust is sucked into the casing, and after being filtered by the cloth bag, the dust gradually accumulates in the conical ash hopper of the casing, and clean air flows out from the air outlet. At present, due to stickiness, humidity and other reasons, the dust accumulated in the conical ash hopper will accumulate at the discharge port of the conical ash hopper, and harden and harden, resulting in the failure of normal discharge of dust. Therefore, a fly ash feeding device for a bag filter is designed, which can prevent the clogging of the outlet of the conical ash hopper.
