Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bag dust collectors, and in particular to a dust discharging device for bag dust collectors. Background Art
[0002] Bag filter is a dry dust filter that can significantly reduce the emission of smoke and dust, so it is widely used in polluting industries. When dusty smoke enters the bag filter, the dust with large particles and high specific gravity settles into the ash hopper due to its own gravity, while the dust is retained when the gas containing finer dust passes through the filter bag, and finally the gas and dust are separated, the clean gas is discharged upward, and the dust falls downward into the ash hopper and is discharged through the discharge valve.
[0003] When the ash hopper at the bottom of the existing bag dust collector is unloading, if it is found that the amount of dust discharged is small or no dust is discharged at all, it may be because of bridging phenomenon in the ash hopper. The reason is that the dust adheres or even sticks due to moisture. If the dust adheres to the inner surface of the bag dust collector box after getting damp, it will affect the fluidity of the dust, resulting in failure to unload smoothly, affecting the normal operation of the ash unloading.
[0004] Therefore, we propose a dust unloading device for bag dust collector to solve this problem.

After reaching the specified amount, the electronic weighing sensor 12 sends a signal to the second motor 6, so that the second motor 6 drives the second rotating shaft 10 to rotate, and the second rotating shaft 10 drives the weighing plate 11 to rotate, and the dust on the weighing plate 11 is poured out from the ash discharge port 5; through the scraper 7, the dust adhered to the inner wall of the hopper 1 due to moisture can be scraped off in time, so that the inner wall of the hopper 1 remains smooth, and the bridge phenomenon of dust accumulation is prevented, ensuring that the ash discharge work can be carried out normally, which can reduce the maintenance cost of the equipment, extend the service life of the equipment, and reduce the safety hazards caused by dust accumulation. Through the weighing plate 11, the dust can be flipped out of the ash discharge port 5 after reaching the specified amount.
