Description

Technical Field

[0001] The utility model relates to the technical field of air permeable dust removal devices, in particular to an air permeable dust removal device with the effect of maintaining air pressure balance. Background Art

[0002] During laser welding of aluminum-silicon coated hot-formed steel, the aluminum-silicon coating on the steel plate will form dust mist, which requires a dust removal device to deal with the dust mist. However, due to the large width of the steel plate, the pressure of the dust suction ports on the left and right sides of the steel plate needs to be adjusted evenly to maintain air pressure balance, so the dust removal device needs to be improved.

In the utility model, the fan in the fixing rod is started by the fan, the fixing rod, the electric telescopic rod and the main gear, and the pushing rod drives the rotating frame, the rotating frame rotates with the rotating shaft as the center, and the moving circle moves back and forth in the fixing shaft, so that the fixed shaft swings in the filter box with the main gear as the center, the main gear is meshed with the sub-gear, and the fixing block rotates with the fixing rod inside the filter box, so that the fan can swing back and forth facing the filter element. By adding a fan inside the filter box to increase the suction force, it is ensured that the wind drawn into the filter box is completely discharged, so that the air pressure in the holding bin can be balanced.

[0004] Although the above scheme ensures that the wind drawn into the filter box is completely discharged so that the air pressure in the bin is balanced, the existing dust removal device needs to make the pressure of the two dust suction ports uniform during the dust removal process, and at the same time prevent dust mist from overflowing, so that each dust suction port can absorb its own range, and it is difficult to replace the dust suction hopper to adjust the size of the dust suction port in the dust removal device.
