[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 The top of the bottom plate 1 is fixedly provided with an outer ring 16, and the bottom plate 1 is provided with an outer ring 17. The outer ring 18 is connected to the bottom plate 1 by a screw thread, and the screw thread is connected to the top of the bottom plate 1 by a screw thread.

[0019] In this embodiment: first, the cooled granular steel slag is added to the inner filter cartridge 18 through the feed pipe 9, and the rotating mechanism is started at this time. The rotating mechanism drives the rotary drum 5 to rotate, and the rotary drum 5 drives the outer filter cartridge 19 and the inner filter cartridge 18 to rotate synchronously. The added granular steel slag is screened into the outer filter cartridge 19 and the rotary drum 5 according to size during rotation. The granular steel slag located in the rotary drum 5 is the smallest in size, the granular steel slag located in the outer filter cartridge 19 is of medium size, and the granular steel slag located in the inner filter cartridge 18 is the largest in size. After screening is completed, the screened steel slag is discharged from the discharging mechanism, completing the coarse screening process.

[0020] Please refer to Figure 1 、 Figure 2 and Figure 3 The rotating mechanism includes two groups of brackets 2 fixedly mounted on the top of the base plate 1, a rotating shaft 3 is rotatably mounted on the top of the bracket 2, and support wheels 4 are fixedly connected to both ends of the rotating shaft 3. The rotating mechanism also includes a limiting ring 6 integrally formed with the outer periphery of the rotating drum 5, the limiting ring 6 is in contact with the support wheel 4 and is connected in an annular sliding manner, and a gear ring 20 is fixedly mounted on the outer wall of the rotating drum 5 between the two limiting rings 6. A rotating motor 15 is installed on the top of the base plate 1 through a mounting frame, and the output end of the rotating motor 15 is connected to a gear 21 meshing with the gear ring 20.

[0021] In this embodiment: by starting the rotating motor 15, the rotating motor 15 runs the driving gear 21 to rotate, the rotating gear 21 drives the gear ring 20 to rotate, the rotating gear ring 20 synchronously drives the rotating drum 5 to rotate, and the rotating drum 5 drives the limiting ring 6 to rotate. At this time, the support wheel 4 rotates under the friction force, and the support wheel 4 provides rotational support for the rotating drum 5.

[0022] Please refer to Figure 1 、 Figure 2 and Figure 3 The discharging mechanism includes three discharge ports 10 opened inside the rear end plate 8, and the outer end of the rear end plate 8 is fixedly connected to the discharge port 10 and three slides 11 protruding outward. The three slides 11 are respectively used to discharge the materials in the inner cavity of the rotating drum 5, the discharge port 10, and the inner filter cartridge 18, and the lengths of the three slides 11 gradually become shorter from top to bottom. The discharging mechanism also includes an electric push cylinder 14 fixedly installed on the top of the bottom plate 1, and the output end of the electric push cylinder 14 is fixedly connected to the vertical plate 13, and one end of the vertical plate 13 is fixedly connected to three cross bars 12. The ends of the three cross bars 12 away from the vertical plate 13 are fixedly connected to a blocking plate 16 for closing the discharge port 10. The three blocking plates 16 are located on both sides of one end inside the rotating drum 5, the outer filter cartridge 19, and the inner filter cartridge 18, and are formed with guide inclined surfaces 17.

[0023] In this embodiment: after the screening is completed, the electric push cylinder 14 is started to run, the electric push cylinder 14 is shortened, and the output end of the electric push cylinder 14 drives the three cross bars 12 to move synchronously toward the inside of the drum 5 through the vertical plate 13, and the three cross bars 12 push the three blocking plates 16 to move synchronously until the blocking plates 16 are completely dislocated from the discharge port 10. At this time, the materials located in the drum 5, the outer filter cartridge 19, and the inner filter cartridge 18 are discharged through the three slides 11 respectively, and are discharged outward through the discharge port 10 smoothly under the action of the guide surface 17 during the sliding process of the granular steel slag, avoiding the influence of the blocking plate 16 on the discharge of the material.
