It should be noted that the power of the fan 41 should not be too high to prevent the smoke dust falling normally in the smoke dust bin 1 from being sucked into the ventilation cloth bag 42, and the burden of the dust collection assembly 4 is increased.

In some embodiments, the smoke dust bin 1 comprises a cylindrical section 11 and a conical section 12 which are connected, the air suction hood 2 and the bag breaking assembly 3 are both installed at the upper end of the cylindrical section 11, the lower end of the cylindrical section 11 is connected with the upper end of the conical section 12, the feeding port 111 is located at the upper end of the cylindrical section 11, the discharging port 121 is located at the lower end of the conical section 12, the cross-sectional area of the cylindrical section 11 is kept constant in the vertical direction, and the cross-sectional area of the conical section 12 is gradually reduced in the direction from top to bottom.

From this, the smoke and dust in ton bag 6 is earlier through cylindricality section 11, later falls into in the toper section 12, because toper section 12 has certain slope, and the smoke and dust slides down to discharge gate 121 under the action of gravity to enter into the treatment facility through discharge gate 121 in, can effectively avoid the smoke and dust to pile up.

In some embodiments, the conical section 12 and/or the cylindrical section 11 are/is provided with a fluidization interface, the fluidization interface is used for introducing fluidization gas into the smoke dust bin 1, the smoke dust is likely to absorb water during the recycling process, hardening is likely to occur during the discharging process in the smoke dust bin 1, so that the discharging is not smooth, the smoke dust is accumulated at the discharge port 121, the normal operation of the flow is seriously affected, the fluidization interface is arranged to introduce fluidization gas into the smoke dust bin 1, so that the smoke dust in the smoke dust bin 1 is effectively loosened, and the normal discharging of the smoke dust bin 1 is ensured.

Preferably, only the conical section 12 is provided with the fluidization interface, since the hardening phenomenon is mainly concentrated at the position of the discharge hole 121, and therefore, the use requirement can be met only by providing the fluidization interface on the conical section 12. The fluidization interfaces are multiple and are uniformly distributed on the outer surface of the conical section 12, and the fluidization gas is introduced into the smoke dust bin 1 through the fluidization interfaces simultaneously, so that the effect of loosening smoke dust is better.
