Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material conveying equipment, in particular to a magnetic flow control and material falling device for a belt conveyor transfer point. BACKGROUND

[0002] The current belt conveyor transfer point uses a material falling pipe to convey the material from the feeding belt conveyor to the receiving belt conveyor, and then the material is conveyed to the designated location by the receiving belt conveyor. The conventional material falling device used in the transfer point has a head funnel below the feeding belt, a flow guide baffle in the head funnel, an electric three-way valve below the head funnel for switching the material flow, a material falling pipe below the electric three-way valve for material falling, and a buffer air lock between the lower end of the material falling pipe and the receiving belt for conveying the material to the receiving belt conveyor and then to the designated location.

[0003] In such a transfer feeding device, the flow guide baffles in the head funnel are flat plates, and the plate surface is basically perpendicular to the material flow direction. The material directly impacting the flow guide baffles is easy to break and generate dust. The conventional material falling pipe below the head funnel causes the material to impact the wall plate in free fall, which is easy to generate dust, and the material falling pipe is also easy to break. At the same time, the fast material flow speed generates negative pressure, which absorbs the surrounding air and material mixture, and the mixed air material falls on the belt and squeezes out air, generating a large amount of dust. Finally, the fast speed drives air into the guide chute to form a high positive pressure, and the large wind speed causes dust to fly everywhere. The buffer air lock at the material falling point of the receiving belt is easy to cause material blockage. When conveying wet material, part of the material will adhere to the flap, and the accumulation will increase over time, eventually causing the air lock to fail. Moreover, when the material impacts the flap, the impact dust is also large, which further generates induced wind, which is not conducive to environmental protection.

[0004] Chinese patent CN204549337U discloses a belt conveyor transfer point anti-blocking dust suppression and flow control material falling device. Since the flow control engine groove, flow control intermediate pipe, and flow control feeding spoon pipe are designed in an arc shape, the impact angle and impact force of the material flow on the flow control engine groove, flow control intermediate pipe, and flow control feeding spoon pipe are small, the service life of the pipe fittings is long, material breaking and dust generation can be effectively prevented, the hanging and blocking problem of the conventional material falling pipe at the corner can be effectively solved, the material flow speed and flow form can be controlled, the material moves along the inner wall of each component during movement, the induced wind amount in each component can be maximally reduced, the carrying and movement of dust can be reduced, and the generation of dust can be reduced from the source.

[0005] However, in the bulk material transfer conveyor system, the incoming material belt conveyor falls from the head to the tail (or any position in the middle) of the receiving belt conveyor in the transfer station, and is transferred through the vertical chute (or falling chute), which causes the inside of the chute to be impacted by the bulk material, resulting in the impact and breakage of the conveyed material, the generation of a large amount of dust, a large amount of noise, and rapid wear of the lining plate inside the chute. SUMMARY
