When a large amount of iron ore powder 5 is mixed in the outer rings of the two rollers 10, the vibration mechanism 26 and the electric fan 35 are started, the first motor 13 is started, the first motor 13 drives the two rollers 10 to synchronously rotate, the brush bristles 34 on the second arc-shaped plate 33 can scrape the iron ore powder 5 on the outer ring of the roller 10 in the rotating process of the roller 10, and the iron ore powder 5 mixed in the outer ring of the roller 10 can be cleaned more quickly by combining the wind of the electric fan 35 and the vibration of the vibration mechanism 26.
Further, as shown in the figure, the outer side of the outer ring of the drum 10 described in this embodiment is wrapped with a second circular air bag 39 in a circular ring shape, a fourth circular hole is formed in the outer ring of the second air bag 39 at a position corresponding to the hemisphere 17, the outer arc surface of the hemisphere 17 is fixed on the inner ring of the fourth circular hole, the front end and the rear end of the second air bag 39 are fixed on the front end and the rear end of the drum 10, and the second air bag 39 is internally sealed. The second air bag 39 can effectively prevent the iron ore powder 5 from directly contacting the outer ring of the roller 10, thereby increasing the difficulty of the cleaning mechanism for cleaning the iron ore powder 5 on the outer ring of the roller 10; because the inner wall of the second air bag 39 is sealed, the second air bag 39 is blown by the cleaning mechanism in the process of cleaning the iron ore powder 5 on the surface of the roller 10 and when the iron ore powder 5 is squeezed into the gap between two adjacent hemispheroids 17, so that the second air bag 39 is deformed, and the second air bag 39 is deformed to shake out the iron ore powder 5 at other positions on the outer ring of the second air bag 39.
Further, as shown in the drawings, the lower end of the vibration mechanism 26 of the present embodiment is provided with a damping mechanism 41, and the vibration mechanism 26 contacts with the ground through the damping mechanism 41. The vibration of the ground caused by the vibration mechanism 26 can be reduced.
Furthermore, the soft sleeve is softer, and the soft sleeve is wrapped on the outer side surfaces of the first inclined plate 22, the first arc-shaped plate 23 and the second inclined plate 24. The soft sleeve can prevent the contact between the pelletized iron ore powder 5 and hard objects to cause the pelletized iron ore powder 5 to be scattered.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
