Description

Technical Field

[0001] The utility model belongs to the technical field of iron debris suction removal and relates to a belt-type electromagnetic suction system device. Background Art

[0002] With the rapid development of domestic infrastructure and the continuous improvement of the durability of high-performance concrete, the production line of the gravel field has entered the era of standardization, intelligence, automation and informatization. The parent rock material of the gravel field comes from tunnel slag, which is excavated by drilling and blasting. During the tunnel excavation and construction process, there are usually many metal debris in the stone, such as gun wires, wires, steel bars, anchors and other iron materials. If these iron debris enter the crusher cavity, it will not only damage the gravel production equipment and conveyor belts, but also affect the quality of the raw material products. Manual removal cannot achieve the standardized production line operation, so the iron objects in the stone must be removed before the stone enters the crusher cavity. Therefore, this kind of belt-type electromagnetic suction system device can effectively solve these problems, effectively ensuring standard intelligent operation, the safety of people and equipment, and the quality of raw material production.

[0003] At present, an electromagnetic iron remover is usually used to suck up iron impurities in construction waste and gravel on the conveyor belt after being powered on, so as to remove iron impurities in construction waste and gravel. The existing iron debris suction device is usually a rectangular electromagnet set above the gravel production line. Once the electromagnet is saturated, it needs to be moved to the unloading point. After the electromagnet is powered off and demagnetized, the sucked iron debris is recovered. This process will waste a lot of time and seriously affect the working efficiency of the electromagnet. At the same time, the height of the electromagnet cannot be adjusted according to the height of the gravel transported on the gravel production line, and it is not flexible to use.

The electromagnetic device is set above the conveying device 12 for conveying the crushed stone, so that the electromagnet 5 absorbs the iron debris on the conveying device 12. The iron debris is fixed on the conveyor belt under the suction of the electromagnet 5 and moves with the conveyor belt and gradually moves away from the electromagnet 5. As the iron debris moves away, the attraction of the electromagnet 5 gradually decreases, and finally falls into the collecting device 14 under the action of gravity.

The support includes pillars located on both sides of the conveying device 12 and a box body 1 arranged between the two pillars. The box body 1 is surrounded by four outer walls, and the bottom of the box body 1 and the side facing the collection device 14 are open structures. The electromagnetic suction device is fixed inside the box body 1.

[0027] The transmission device includes a driving wheel 2 and a driven wheel 3, and the two ends of the belt are respectively sleeved on the outer circumference of the driving wheel 2 and the driven wheel 3.
