[0032] Embodiment 1:

[0033] like Figures 1 to 3 As shown, the utility model provides an iron removal device for belt conveying materials, comprising: a fixed frame 1 for installing a screen structure, the fixed frame 1 comprising a first support section 101 and a second support section 102, the first support section 101 and the second support section 102 are arranged relatively along a first direction X, the fixed frame 1 is made of steel, the structure is simple and practical, and the manufacturing and maintenance costs are low; a screen structure, the screen structure comprises a plurality of strong magnetic screen bars 2, the plurality of strong magnetic screen bars 2 are arranged in the fixed frame 1 at intervals along a second direction, the first end of each of the strong magnetic screen bars 2 is detachably connected to the first support section 101, and the second end is detachably connected to the second support section 102, and the first end of the strong magnetic screen bar 2 in the vertical direction is higher than the second end of the strong magnetic screen bar 2, wherein the second direction extends in the horizontal direction and is perpendicular to the first direction. A belt conveyor is arranged below the screen structure, and after the screened material is screened by the screen structure, the ironware and other sharp objects entrained in the material are removed and fall to the belt conveyor below the screen structure to be transported to the next process. In this embodiment, the strong magnetic screen bar 2 is tilted to facilitate the flow of the material to be screened and improve its screening effect. The tilt angle of the strong magnetic screen bar 2 can be adjusted according to factors such as material characteristics, conveying volume, and on-site conditions. In this embodiment, the strong magnetic screen bar is tilted in a fixed frame, the overall structure is simple, and the manufacturing and maintenance costs are low. Only the adsorption of the strong magnetic screen bar 2 can be used to remove iron objects and other objects that damage the belt in the material, without consuming electricity, and has strong anti-interference ability, which reduces the risk of belt tearing.

The strong magnetic screen bars 2 are combined with the supporting screen bars 3 to form a screen structure with strong magnetic adsorption and filtering properties, which can not only screen out scrap iron and other belt-damaging objects entrained in the material to achieve the effect of removing iron objects, but also remove other larger debris through the gap between the two screen bars. The supporting screen bars 3 are made of a material with strong wear resistance, such as spring steel. Figure 5As shown in the figure, the strong magnetic sieve bar 2 includes wear-resistant steel 201 and a strong magnet 202; the wear-resistant steel 201 is coated on the outer periphery of the strong magnet 202 to protect the strong magnet 202, improve the service life of the strong magnet, and does not affect the adsorption performance of the strong magnet 202.

The reinforcing bar 106 can be arranged at the top and bottom of the first support plate 103 and the adjustment plate 104. Specifically, during implementation, it is only necessary not to affect the layout of the belt conveyor below the screen structure.

[0037] As Figure 4 shown, the adjustment plate 104 includes a plate body, and the plate body is provided with a plurality of adjustment holes 105 arranged at intervals in the second direction. The plate body is arranged opposite to the first support plate 103 in the first direction, and the second end of the strong magnetic sieve bar 2 is detachably installed in the adjustment holes 105.
