[0002] Scrap steel refers to steel scrap that is not used as a product during the steelmaking process, as well as steel materials from equipment and components that are scrapped after use. Steel scrap is called scrap steel, and pig iron scrap is called scrap iron. They are collectively referred to as scrap steel.

[0003] Chinese patent discloses a device for recovering scrap steel from industrial waste (authorization announcement number CN214716891U). This patented technology can solve the problems in the existing technology that the machinery industry generates a large amount of industrial waste such as cutting chips, grinding chips, and waste molding sand during the production process. These wastes tend to accumulate and solidify into lumps over a long period of time. The lumps of industrial waste are inconvenient to crush, time-consuming and labor-intensive, and have poor recycling effect and low efficiency, which is not conducive to the recovery of scrap steel from industrial waste.

[0004] Existing scrap steel recycling methods are too simplistic, resulting in unsatisfactory recycling effects. Furthermore, using a filter screen structure can easily cause the mesh to become clogged. Utility Model Content

[0009] The technical effects and advantages of this utility model are as follows:

[0010] 1. This utility model employs a first filter screen and a second filter screen, adopting a multi-filter screen structure, which facilitates the detailed classification and processing of steel chips and makes it easy to collect and reuse them. Furthermore, the use of an adjusting cam and an arc-shaped plate structure causes the second filter screen to vibrate, further improving the effect of steel chips rolling off and preventing steel chips from clogging the filter screen mesh.

[0011] 2. The present invention adopts a guide plate structure, which guides the steel chips, prolongs the rolling time of the steel chips, and further improves the rolling effect of the steel chips. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Please see Figures 1-5This embodiment provides a fine-grind scrap steel recycling and screening device, including a base platform 1 and a first filter screen 2. The first filter screen 2 is arranged above the base platform 1, and a second filter screen 12 is installed below the first filter screen 2 via a connecting rod 11. Both the first filter screen 2 and the second filter screen 12 are arranged at an angle. A first vertical cavity 13 is arranged to the right of the first filter screen 2, a second vertical cavity 14 is arranged below the first vertical cavity 13, and a third vertical cavity 15 is arranged below the second filter screen 12. The mesh size of the first filter screen 2 is larger than that of the second filter screen 12. During operation, scrap steel chips fall onto the first filter screen 2 and are rolled. Smaller particles fall onto the second filter screen 12 and continue to roll. Even smaller scrap steel chips fall into the third vertical cavity 15. The first vertical cavity 13 and the second vertical cavity 14 collect the scrap steel chips that roll off the first filter screen 2 and the second filter screen 12, respectively. The multi-filter structure facilitates fine classification of the scrap steel chips and makes them easy to collect and reuse.

[0020] The first filter screen 2 has an upper cavity 16 installed on its left end face, and an adjusting cylinder 17 is installed on the left end face of the base 1. A push plate 18 is installed on the output end of the adjusting cylinder 17. When working, steel chips are placed in the upper cavity 16. The adjusting cylinder 17 is started, which drives the push plate 18 to move to the right, thereby pushing the steel chips onto the first filter screen 2. The operation is convenient and labor-saving.

[0021] A spring rod 19 is installed at the bottom of the upper cavity 16, and an arc-shaped plate 21 is installed at the bottom of the spring rod 19. An adjusting cam 22 is arranged below the arc-shaped plate 21, and an adjusting motor 23 is installed on the rear end face of the adjusting cam 22. A control panel 24 is installed on the left end face of the base 1. The control panel 24 and the adjusting motor 23 are electrically connected. During operation, a PLC program is written in the control panel 24 to control the operation of each device. When the adjusting motor 23 starts, it drives the adjusting cam 22 to rotate. The adjusting cam 22 lifts the arc-shaped plate 21, and the spring rod 19 resets the arc-shaped plate 21, thereby causing the arc-shaped plate 21 to shake up and down, which beats the bottom of the second filter screen 12, making the second filter screen 12 shake. This further improves the effect of steel chips rolling off and prevents steel chips from clogging the filter screen mesh.

[0022] The first filter screen 2 has multiple sets of guide plates 25 installed on its upward inclined end face. The guide plates 25 have a wavy plate structure. When the steel chips roll off the first filter screen 2 during operation, the guide plates 25 guide them, prolonging the rolling time of the steel chips and further improving the rolling effect of the steel chips.

[0023] In actual operation, steel shavings are placed in the upper chamber 16. The regulating cylinder 17 is activated, which drives the push plate 18 to move to the right, thereby pushing the steel shavings onto the first filter screen 2. The operation is convenient and labor-saving. The waste steel shavings fall onto the first filter screen 2 for rolling treatment. Small particles fall onto the second filter screen 12 for further rolling treatment. Even smaller steel shavings fall into the third vertical chamber 15. The first vertical chamber 13 and the second vertical chamber 14 collect and treat the steel shavings that fall onto the first filter screen 2 and the second filter screen 12, respectively. The multi-filter structure facilitates the detailed classification and treatment of steel shavings, making it easy for them to be reused.
