Description

Automatic dredging device for blocking of smoke dust blanking hopper

Technical Field

The utility model relates to a cigarette manufacturing field especially relates to an automatic pull throughs of smoke and dust blanking fill jam.

Background

The smoke dust and the tobacco soil mainly comprise soil dust attached to tobacco leaves, finely broken tobacco powder, finely cut stems with different lengths, widths and thicknesses and the like, and are characterized by small density and particulate matters such as dust and fragments. In the tobacco processing, for the purpose of protecting the environment, the smoke dust is subjected to cloth bag filtration, is recovered and then is extruded and molded, and is finally subjected to biodegradation treatment to be reused as an organic fertilizer.

Generally, in the smoke recycling and conveying processes, blanking hoppers are mostly used for blanking, but the blanking hoppers can often generate a blocking phenomenon, and through practical application observation and analysis, the blocking mechanism is mainly that in the material falling process, materials are adhered to the inner wall of the inclined blanking hopper, the smoke soil density of the smoke is smaller, the flow and the material humidity are also larger, so that the adhesive force of the inner wall of the blanking hopper with the smaller inclination angle is increased, in particular, when the shelving phenomenon occurs, as shown in figure 1, a blanking port at the bottom of the blanking hopper is in a hollow area, the materials do not fall any more, the material level on the upper portion of the blanking hopper is continuously piled high to generate blocking, equipment is directly forced to stop in severe cases, and the maintenance hole or the observation window of the blanking hopper needs to be manually opened for dredging treatment.
