According to the attached drawings 4-5, side fixed mounting of movable plate 8 has stopper 104 in the device, stopper 104 sliding connection is at the inside wall of sack cleaner 2, spacing groove 11 has been seted up to the inside wall of sack cleaner 2, stopper 104 sliding connection is in the inside of spacing groove 11, fixed mounting has telescopic link 12 between the inside wall of spacing groove 11 and one side of stopper 104, spring 13 has been cup jointed in the surface activity of telescopic link 12, when contactless between a set of push pedal 102 and connecting plate 103, the external force impetus that movable plate 8 received disappears this moment, and then make one side of movable plate 8 remove to the direction of keeping away from sack main part 6 under the effect of telescopic link 12 and spring 13, so that carry out the vibration operation of one side down.

The working principle is as follows:

when the dust removing device is in an initial state, one side of the moving plate 8, which is not provided with the limiting block 104, is not in contact with the outer surface of the cloth bag frame 7, one end of the connecting plate 103, which is arranged on the lower surface of one side of the moving plate 8, which is provided with the limiting block 104, is abutted against the side surfaces of the group of push plates 102, and at the moment, the telescopic rod 12 and the spring 13, which are arranged between the limiting block 104 and the limiting groove 11, are in an extending state.

Further, when carrying out dust removal work, at first be connected sack cleaner 2's air inlet 3 through the connecting pipe with steelmaking converter, make the waste gas that steelmaking converter in-process produced move to sack cleaner 2's inside through air inlet 3, then waste gas is along with the air current rebound, make waste gas pass through the inside multiunit sack main part 6 that sets up of sack cleaner 2, impurity such as the dust that contains in the gas this moment is adsorbed at the lateral wall of sack main part 6, then, the inside of sack cleaner 2 is discharged through gas outlet 4 to the gas after the filtration.

Further, after accomplishing quantitative waste gas and removing dust, can take off sheltering from of discharge gate 9 department that the 2 bottom of sack cleaner was seted up earlier this moment, then make the inside dust of multiunit sack main part 6 remove the inside of sack cleaner 2 through discharge gate 9 under the action of gravity.

And simultaneously, in the process of discharging the dust, the rotating rod 101 can be rotated clockwise, so that the rotating rod 101 drives the multiple groups of push plates 102 to rotate, the multiple groups of push plates 102 are contacted with the connecting plates 103 arranged on the lower surface of the movable plate 8 and drive the movable plate 8 to move in the bag-type dust collector 2, one side of the movable plate 8 is collided with the bag frame 7 arranged on the outer surface of the bag main body 6 continuously, the dust adhered to the side wall of the bag main body 6 is enabled to fall out of the bag main body 6 under the impact effect, and the cleaning efficiency of the dust is improved.

Finally, after the dust removal operation is completed, the operator stops rotating the rotating rod 101 at this time, so that the pushing action of the pushing plate 102 on the connecting plate 103 disappears, and further the pushing action of the external force on the moving plate 8 disappears, so that the side, which is not provided with the limiting block 104, of the moving plate 8 moves in the direction away from the cloth bag main body 6 under the action of the telescopic rod 12 and the spring 13, and the moving plate returns to the initial state, and the vibration operation of the next side is performed.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof.
