These metals affect the quality of papermaking raw materials. Therefore, before using papermaking raw materials, these impurities such as metals need to be screened out.

[0003] The traditional method is to first screen the papermaking raw materials using a screening device, and then send the papermaking raw materials to a designated location through a conveying device. However, this method not only has many processes and is time-consuming, but also has a very complicated structure.

[0004] The prior art discloses a patent with the announcement number CN105253522B. The solution includes a first belt conveyor, with baffles erected on both sides to enclose the first belt conveyor into a container space with an upper opening, and the first belt conveyor is arranged horizontally; the second belt conveyor is inclined at 25-35 degrees relative to the ground, and the lower end overlaps below the output end of the first belt conveyor. While conveying papermaking raw materials, the raw materials are first layered, and the larger raw materials are separated first, and then the debris and raw materials are separated to improve the separation effect.

[0005] The existing devices including the above patents gradually exposed the shortcomings of the existing technology as they were used, mainly in the following aspects:

[0006] First, during the conveying process of papermaking raw materials by the existing conveyor, due to the different thicknesses of the raw material piles on the conveyor, the existing screening device cannot screen the metals in the raw material piles of different thicknesses, thereby reducing the screening efficiency.

[0007] Second, when the existing screening structure is in use, the screened metal accumulates on the screening structure, which requires the metal on the screening structure to be processed regularly, thereby affecting the screening efficiency of the metal in the papermaking raw material.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
