Description

Technical Field

[0001] The utility model belongs to the technical field of dust collectors, and in particular relates to an automatic dust unloading device for a dust collector. Background Art

[0002] The dust unloading device of the dust collector discharges dust through an ash hopper and an ash discharge valve. Under the action of gravity, the dust falls downward by itself relying on its mass to complete the ash unloading process. For manual ash unloading valves and pneumatic ash unloading valves, the dust is unloaded to complete the ash unloading process, which is completed by the dust's own weight falling. In addition, the dust may adhere to the inner wall of the ash unloading valve for various reasons, and the dust on the inner wall of the ash unloading valve cannot be cleaned. When a lot of dust accumulates on the inner wall of the ash unloading valve, it will affect the ash unloading efficiency. Therefore, the existing ash unloading device cannot quickly realize ash unloading. For this reason, we propose an automatic ash unloading device for a dust collector. Utility Model Content
