When the screening mesh is blocked by the steel slag, the staff moves the rotating rod, and the rotating rod drives the moving plate and the cleaning rod to rotate. At this time, the coil spring deforms. When the cleaning rod is inserted into the screening holes of the screening mesh, the steel slag in the screening holes is squeezed out by the cleaning rod, so as to achieve the effect of cleaning the screening mesh. Finally, the staff releases the rotating rod, and under the action of the restoring elastic force of the coil spring, the moving plate moves back to the vertical state and fits against the inner wall of the housing.

[0027] Refer to Figures 1-5 As shown, this embodiment discloses a pre - screening device for steel slag magnetic separation processing, including an outer shell 1. The upper surface of the outer shell 1 is fixedly connected with a feeding frame 2. One side of the outer shell 1 is provided with a discharge port 3. A screening mesh 4 is arranged inside the outer shell 1. A number of screening holes are evenly arranged on the surface of the screening mesh 4. The discharge port 3 is located below the screening mesh 4. The outer shell 1 is provided with a reserved hole 5 corresponding to the screening mesh 4. A cleaning device 6 is arranged on the upper surface of the screening mesh 4. A collection device 7 is arranged on one side of the outer shell 1.

[0028] Refer to Figures 1-5As shown, the cleaning device 6 includes four backing plates 61 which are fixedly connected to the upper surface of the screening mesh 4. The four backing plates 61 are equally divided into two groups. A same rotating rod 62 is rotatably connected to the surface of each group of backing plates 61. A moving plate 63 is fixedly connected to the arc surface of the rotating rod 62. A cleaning rod 64 is fixedly connected to the moving plate 63 corresponding to the screening holes. The size of the cleaning rod 64 is smaller than the size of the screening holes. Two symmetrically arranged torsion springs 68 are sleeved on the arc surface of the rotating rod 62. The two ends of the torsion springs 68 are respectively fixedly connected to the moving plate 63 and the backing plate 61. When screening steel slag is required, the staff puts the steel slag into the interior of the housing 1 through the feed frame 2. The screening mesh 4 screens the steel slag. The smaller steel slag passes through the screening holes of the screening mesh 4 and drops below the screening mesh 4, and flows out of the housing 1 from the discharge port 3. While the steel slag with too large volume flows out from the reserved hole 5 and requires the staff to reprocess it. When the screening mesh 4 is blocked by the steel slag, the staff moves the rotating rod 62. The rotating rod 62 drives the moving plate 63 and the cleaning rod 64 to rotate. At this time, the torsion springs 68 are deformed. When the cleaning rod 64 is inserted into the screening holes of the screening mesh 4, the steel slag in the screening holes is extruded by the cleaning rod 64, thus achieving the effect of cleaning the screening mesh 4. Finally, the staff releases the rotating rod 62. Under the action of the restoring elastic force of the torsion springs 68, the moving plate 63 moves back to the vertical state and fits against the inner wall of the housing 1. Through the cleaning device 6, the effect of cleaning the screening holes of the screening mesh 4 is achieved, avoiding the situation that the screening mesh 4 is blocked by the steel slag, which may lead to the abnormal use of the screening equipment.

[0029] Refer to Figures 1-5 As shown, a slider 67 is fixedly connected to one side of the moving plate 63. An arc-shaped slide rail 66 is fixedly connected to the screening mesh 4 corresponding to the slider 67. The inner wall size of the slide rail 66 is adapted to the size of the slider 67. By moving the slider 67 inside the slide rail 66, the effect of restricting the moving direction of the moving plate 63 is achieved, thereby improving the stability of the rotation of the moving plate 63. One end of the rotating rod 62 located outside the housing 1 is fixedly connected to a handle 69. The surface of the handle 69 is provided with anti-slip lines. By providing the handle 69, the effect of facilitating the staff to move the rotating rod 62 is achieved, bringing convenience to the staff. A pointed protrusion 65 is fixedly connected to the end of the cleaning rod 64 far from the moving plate 63. The tip of the pointed protrusion 65 is far from the cleaning rod 64. By providing the pointed protrusion 65, it is convenient for the cleaning rod 64 to be inserted into the screening holes of the screening mesh 4, bringing convenience to the staff to clean the screening holes.

[0030] Refer to Figures 1-5As shown in the figure, the collecting device 7 includes a fixing plate 71 which is fixedly connected to one side of the outer shell 1. The fixing plate 71 is located directly below the reserved hole 5. A limiting groove 73 is formed on the upper surface of the fixing plate 71. The collecting frame 72 is arranged on the fixing plate 71 by means of the limiting groove 73, and the size of the collecting frame 72 is adapted to the size of the limiting groove 73. Before the outer shell 1 screens the steel slag, the staff moves the collecting frame 72 and places the collecting frame 72 into the limiting groove 73 of the fixing plate 71, achieving the effect of fixing the collecting frame 72. Through the collecting frame 72 provided by the collecting device 7, the steel slag flowing out of the reserved hole 5 is collected, which is convenient for the staff to uniformly process the unqualified steel slag and brings convenience to the staff.

[0031] Refer to Figures 1-5 As shown in the figure, two symmetric triangular plates 74 are fixedly connected to the upper surface of the fixing plate 71, and one side of the triangular plate 74 is fixedly connected to the outer shell 1. By setting the triangular plate 74, the outer shell 1 and the fixing plate 71 to form a stable triangular structure, the stability of the fixing plate 71 is improved, and the fixing plate 71 is prevented from shaking. A guiding plate 75 is fixedly connected to one side of the collecting frame 72 close to the reserved hole 5, and the guiding plate 75 is inclined. By setting the guiding plate 75, it is convenient to guide the steel slag coming out of the reserved hole 5 into the collecting frame 72, which brings convenience to the staff to collect the steel slag.

[0032] Working principle: Before the outer shell 1 screens the steel slag, the staff moves the collecting frame 72 and places the collecting frame 72 into the limiting groove 73 of the fixing plate 71. The limiting groove 73 limits the collecting frame 72. When it is necessary to screen the steel slag, the staff puts the steel slag into the inner part of the outer shell 1 through the feeding frame 2. The screening net 4 screens the steel slag. The smaller steel slag passes through the screening holes of the screening net 4 and falls below the screening net 4 and flows out of the outer shell 1 from the discharge port 3, while the steel slag with too large volume flows out from the reserved hole 5 and falls into the collecting frame 72 through the guiding plate 75, which is convenient for the staff to uniformly process later. When the screening net 4 is blocked by the steel slag, the staff moves the handle 69, and the handle 69 drives the rotating rod 62 to rotate, and the rotating rod 62 drives the moving plate 63 and the cleaning rod 64 to rotate. At this time, the coil spring 68 deforms. When the cleaning rod 64 inserts into the screening holes of the screening net 4 by means of the sharp protrusion 65, the steel slag in the screening holes is extruded out by the cleaning rod 64, thus achieving the effect of cleaning the screening net 4. Finally, the staff releases the handle 69, and under the action of the restoring elastic force of the coil spring 68, the moving plate 63 moves back to the vertical state and fits against the inner wall of the outer shell 1. Through the cleaning device 6, the screening holes of the screening net 4 are cleaned, and the situation that the screening net 4 is blocked by the steel slag, resulting in the abnormal use of the screening equipment, is avoided.
