Description

TECHNICAL FIELD

[0001] The utility model relates to a dust bag, concretely relates to a pollution prevention and control equipment dust bag. BACKGROUND

[0002] After the dust bag is used for a period of time, due to the effects of screening, collision, retention, diffusion and static electricity, a layer of dust is accumulated on the surface of the filter bag, and this layer of dust is called the initial layer.

[0003] The pollution prevention and control equipment mainly relies on a negative pressure mechanism to suck air with dust around into the dust bag, and the dust in the dust bag adheres to the inner wall of the dust bag. When the dust in the dust bag needs to be treated, only the dust bag can be beaten by hand or a handheld instrument to shake off the dust. However, it is difficult to ensure that all areas are fully cleaned by manual beating, which may lead to insufficient cleaning of some parts. Manual beating not only consumes time and effort, but also makes it difficult to accurately control the force of beating. If the force is too light, the dust cannot be effectively removed, and if the force is too heavy, the dust bag may be damaged. At the same time, during the beating process, the operator directly contacts the dust-containing air, increasing the risk of inhaling harmful particulate matter and being harmful to the health of the operator.
