Description

Technical Field

[0001] The utility model relates to the field of iron removers, in particular to a self-unloading permanent magnetic iron remover. Background Art

[0002] The iron remover uses the property of magnets to absorb iron products to achieve the effect of iron removal within an effective range. The permanent magnetic self-unloading iron remover is composed of a permanent magnetic group, a non-magnetic shell and a belt conveyor structure. The permanent magnetic iron remover is located above the material. When there is ferromagnetic material in the material, it is attracted to the belt by magnetic force. When the belt moves to the non-magnetic area, the ferromagnetic material adhered to the belt is separated from the belt under the action of gravity, achieving the effect of unloading.

[0003] In order to better adapt to different iron removal scenarios, the belt conveyor structure on the permanent magnetic self-unloading iron remover usually has a variable speed effect. If the belt transmission speed is too fast, the adsorbed iron products will be thrown out when they follow the belt transmission to the outlet end. If the operator does not take corresponding protective measures in advance, there will be certain safety hazards. Utility Model Content

The rotating shaft rotates outside the frame, and the second driving component is used to drive the rotating shaft to rotate. The baffle moves around the outside of the transmission belt. When the transmission speed of the transmission belt exceeds a set value, the second driving component drives the baffle to rotate to face the outlet end of the transmission belt.

[0031] Reference Figure 1-Figure 3 A rotating shaft 31 is fixedly arranged at one end of the swing arm 3, and a baffle 4 is fixedly arranged at the other end of the rotating shaft 31 by bolts. The side of the baffle 4 facing the transmission belt 11 is covered with an elastic pad. The rotating shaft 31 rotates outside the frame 1, and the rotation axis direction of the rotating shaft 31 is parallel to the axis direction of the transmission roller 23. The second driving assembly 5 is used to drive the rotating shaft 31 to rotate, and the baffle 4 moves around the outside of the transmission belt 11. When the transmission speed of the transmission belt 11 exceeds the set value, the second driving assembly 5 drives the baffle 4 to rotate to face the outlet end of the transmission belt 11.

The fixed block 12 is located on the side of the rack 52 away from the swivel 54. The two ends of the first spring 53 are respectively fixed on the fixed block 12 and the rack 52. The first spring 53 drives the rack 52 to always move toward the side of the swivel 54. An arc-shaped protrusion 511 is integrally formed at one end of the rack 52 close to the rotating ring 54 . The gear 51 is coaxially arranged on the rotating shaft 31 . The rack 52 is located below the gear 51 and meshes with the gear 51 .
