Description

Technical Field

[0001] The utility model relates to the field of scrap steel screening, and more specifically, to an intelligent screening structure for scrap steel recycling and classification. Background Art

[0002] In the process of production, steel mills generate a large amount of waste materials, and the scrapped equipment and components are composed of steel, and the scraps generated in mechanical processing are collectively referred to as scrap steel. These scrap steels have great recycling value, and can reduce environmental pollution after recycling. Pure scrap steel has greater advantages than ordinary scrap steel when smelting, so we need to screen the scrap steel before recycling it. In the document with publication number CN208098558U, a vibration screening scrap steel device is proposed. Through the coordinated use of a vibration motor, a support plate, a fixed plate and a vibration spring, the broken pieces of different components falling on the screen can be vibrated, and the broken pieces of different components can be vibrated evenly. Through the coordinated use of a bar electromagnet and a screen, the scrap steel can be adsorbed to prevent the scrap steel broken pieces from being distinguished from other broken pieces. Through the coordinated connection of a screw, a bar block, a first bar block, a nut, a spring and a screen, the inclination angle of the screen can be adjusted, so that the impurities that cannot be adsorbed by the bar electromagnet tend to one side for easy screening. When the above-mentioned screening structure is in use, vibration is used to screen the broken blocks. However, in actual use, after the dumped broken blocks are piled together, they are screened by vibration and adsorption of scrap steel. The broken blocks at the upper end move to both sides of the screen with the vibration, and the broken blocks fall off because they are not adsorbed, resulting in the operator having to re-screen the fallen broken blocks afterwards, which is a cumbersome operation. Utility Model Content

[0003] The purpose of the utility model is to overcome the problem in the prior art that the broken blocks at the upper end move to both sides of the screen with the vibration, and the broken blocks fall off because they are not adsorbed, which requires the operator to re-screen the fallen broken blocks afterwards.
