Technical Field

[0001] The utility model relates to the technical field of dust removal, in particular to a dust removal mechanism of a dust collector. Background Art

[0002] Dust removal from a dust collector refers to a series of operations to discharge the collected dust from the dust collector after using dust removal equipment (such as bag dust collectors, electrostatic dust collectors, etc.) for dust control. Star-shaped dust collectors are commonly used dust removal devices for dust collectors. The dust in the dust collector enters the star-shaped dust collector from the silo. The impeller in the star-shaped dust collector brings the dust to the discharge port or discharges it into the discharge pipe, thereby achieving dust removal.

[0003] Dust is prone to compaction during transportation due to humidity and adhesion. When compacted dust enters the star-shaped ash discharger, it is easy to get clogged in the feed pipe or in the ash discharger, affecting the ash discharge efficiency. Summary of the invention

[0024] The outer wall of the rotating drum 5 is in sliding contact with the inner wall of the feed pipe 2, and the top surface of the rotating drum 5 is an inclined surface with the inner edge being lower than the outer edge, in order to avoid dust accumulation at the upper end of the rotating drum 5; an annular groove 12 is provided on the outer wall of the rotating drum 5, and the annular groove 12 is higher than the inclined groove 6, and a limiting rod 13 is provided on the peripheral wall of the feed pipe 2, one end of the limiting rod 13 passes through the feed pipe 2 and extends into the annular groove 12, the limiting rod 13 is fixedly connected to the feed pipe 2, and the end thereof extending into the annular groove 12 is in sliding contact with the annular groove 12.

[0025] Each of the pulverizing rod groups is composed of four horizontally arranged pulverizing rod bodies 14 , and the four pulverizing rod bodies 14 on the same pulverizing rod group are arranged in an array along the central axis of the rotating drum 5 .

[0026] A cross bar 16 is fixed on the inner wall of the feed pipe 2 on the lower side of the rotating drum 5, and a vertical rod 17 located in the rotating drum 5 is fixed on the cross bar 16. The vertical rod 17 is a round rod coaxial with the rotating drum 5. A fixed rod group is provided between each two adjacent upper and lower crushing rod groups. Each of the fixed rod groups is composed of four horizontally arranged fixed rod bodies 18. The four fixed rod bodies 18 on the same fixed rod group are arranged along the central axis of the vertical rod 17. One end of each fixed rod body 18 is fixedly connected to the vertical rod 17 and the other end is close to the inner wall of the rotating drum 5. The crushing rod body 14 and the fixed rod body 18 are both round rod bodies.

[0027] A through hole is provided at the lower end of the connecting rod 11, and a cylinder 22 is fixed on the right side surface of the circular plate 10.
