The utility model discloses the theory of operation as follows:

the exhaust main body 3 is welded at the top of the bag filter, and the floating ball cover 4 at the bottom is screwed down in a threaded connection mode after the hollow floating ball 5 is placed in the exhaust main body, so that the floating ball is prevented from falling. When the filter is not fed with liquid, the hollow floating ball 5 is positioned at the lowest end of the exhaust main body 3 under the action of gravity. When the bag filter is fed with liquid, air is discharged from the top through the through holes 11 around the exhaust body 3. The inner cavity of the automatic exhaust device main body adopts a structure with a big bottom and a small top, and the structure is beneficial to the exhaust of air. When the liquid level rises to the exhaust main body 3, liquid enters from the notch 14 at the bottom of the floating ball cover 4 and supports the hollow floating ball 5, and finally the hollow floating ball 5 presses the sealing O-shaped ring under the action of the buoyancy of the hollow floating ball and the circulating pressure of the liquid in the filter cylinder to form a sealing effect, so that the exhaust process is completed. Otherwise, the floating ball is separated from the sealing O-shaped ring along with the liquid level reduction when the filter cartridge discharges liquid, and air automatically enters the filter. Because the pressure is higher when the filter is full of liquid and circulates, the internal seal of the automatic exhaust device main body adopts the matching seal of the O-shaped ring with small inner diameter and large wire diameter and the hollow floating ball 5 with large diameter, and the sealing structure is more beneficial to the separation of the hollow floating ball 5 from the sealing O-shaped ring when the filter discharges liquid.

The filter overcomes the defects that the liquid inlet of the traditional filter needs manual air exhaust and manual air inlet when liquid is discharged, saves manpower, and can reliably exhaust air to ensure that the filter reaches the optimal working state.

2. The bag filter has the advantages that the mechanical structure with simple and reliable structure is used, so that manpower is liberated, and air in the bag filter can be automatically discharged, so that the bag filter can be safely and effectively filled with liquid. While preventing the occurrence of liquid leakage due to erroneous operation.
