[0002] Among many production fields, some fields will produce a lot of dust during production, such as cement, coal refining and chemical industries. These dusts will not only cause harm to the human body, but also cause irreversible damage to production equipment. Therefore, ventilation devices are often used to ventilate the workshop to ensure that the dust content in the production workshop will not exceed the standard. However, if the dust gas is directly extracted into the atmosphere by a fan, it will cause serious pollution to the outside air and the affected area will become larger. Therefore, these industries need a pulse bag dust removal device to remove dust from the exhaust gas during the ventilation process to ensure that the dust content of the exhaust gas is within a safe area.

[0003] The current pulse bag dust removal device sucks the dusty air in the room into the filter device, and after the dust is removed by the bag device on the bag fixing plate inside the filter device, the filtered gas is discharged through the pulse dust removal cover above the filter device, and the dust on the bag device is flushed away by the pulse gas of the pulse dust removal cover and falls into the storage box below the filter device.

[0004] This pulse bag-type dust removal device not only has a good dust removal effect, but also is convenient for collecting dust. However, when the bag device is installed on the bag fixing plate, it is often not sealed tightly, which will cause a large amount of dust to fly out of the dust removal device without being filtered, which affects the actual filtration efficiency of the device and causes serious pollution to the atmosphere.
