[0041] The complete working principle and steps of the above embodiments are as follows:

[0042] Reference Figures 1 to 5As shown, when the screening device is in the facilitating state, the closure 17 is tightly attached to the left side of the cooler body 14, the bottom of the force storage spring 19 is tightly attached to the left side of the closure 17, the force storage spring 19 is in a natural relaxation state, the telescopic storage box 112 is in a contracted state, and the electromagnet 114 is in a power-off state;

[0043] When the staff uses the screening device to screen the material produced by the smelting furnace, first put the material from the top of the feed port 15 into the inside of the cooler body 14, at this time start the drive gear ring 13, the drive gear ring 13 can drive the cooler body 14 to rotate at the same time, at this time the material can be turned and cooled in the inside of the cooler body 14, because the inside of the closing part 17 is rotatably connected to the left end of the rotating frame 113, and the surface of the rotating frame 113 is symmetrically rotatably connected with eight electromagnets 114, at this time the electromagnets 114 are energized to generate magnetism, when the material is turned in the inside of the cooler body 14, the metal impurities in the material will be attracted by the electromagnets 114, so that the unnecessary metal impurities in the material can be removed, the purity of the material is improved, and the metal impurities in the material can also avoid causing wear to the production equipment in the next process, when the material is cooled, at this time the clamping part 110 is pushed upward in the square hole of the connecting frame 18 to make the bottom of the right side of the clamping part 110 separate from the left side of the closing part 17, and when the clamping part 110 moves upward, the force storage spring 19 is moved to the stretched state, at this time the second fixed frame 16 also needs to be pushed leftward, and when the second fixed frame 16 moves leftward, the closing part 17 is driven to move at the same time, at this time the closing part 17 separates from the left end of the cooler body 14, so that the material in the inside of the cooler body 14 can be taken out, and when the closing part 17 moves leftward, the electromagnets 114 are driven to move outward at the same time through the rotating frame 113, and the metal impurities in the material are attracted to the outer surface of the electromagnets 114, and when the second fixed frame 16 moves leftward, the first guide frame 111 is driven to move at the same time, because the inside of the first guide frame 111 is fixedly connected to the two ends of the left side of the telescopic storage box 112, when the first guide frame 111 moves leftward, the telescopic end of the telescopic storage box 112 is driven to move at the same time, and the right side of the telescopic storage box 112 is fixed to the upper surface of the first fixed frame 1 through the fixed column 115, at this time when the left side of the telescopic storage box 112 moves leftward, the telescopic storage box 112 is pulled upward transversely, and when the telescopic storage box 112 is pulled upward transversely, the supporting rods 116 on the outer surface of the telescopic storage box 112 move leftward along the upper surface of the first guide frame 111, so that the telescopic storage box 112 moves leftward more stably, at this time the length of the telescopic storage box 112 after unfolding is greater than the length of the rotating frame 113, so that the metal impurities on the electromagnets 114 can completely fall into the telescopic storage box 112, the electromagnets 114 are disconnected, and after the electromagnets 114 lose magnetism, the metal impurities fall off from the electromagnets 114, so that the metal impurities can completely fall into the telescopic storage box 112, avoiding the scattering and loss of the impurities.

[0044] Reference Figure 6 and Figure 7 As shown in the figure, when the screening device is in the promoting state, the rack 22 has not been engaged with the gear 21.

[0045] As the cooler body 14 rotates, the rack 22 is rotated by the cooler body 14, and the inner side of the rack 22 is engaged with the outer surface of the gear 21 to rotate the gear 21. The right side of the gear 21 is drivingly connected to the inner side of the bottom of the belt 2, and as the gear 21 rotates, the rotating frame 113 is rotated by the belt 2. The rotating frame 113 rotates to switch the electromagnet 114 on the bottom and the top surface, avoiding poor suction caused by too much adsorption of a single position electromagnet 114. After switching, the overall adsorption efficiency can be improved to ensure that the metal impurities in the material are fully removed.

[0046] Reference Figures 8 to 10 As shown, when the screening device is in the promoting state, the upper surface of the rotating piece 32 is engaged with the right side of the shifting piece 31, the lower surface of the rotating piece 32 is engaged with the left side of the shifting piece 31, and the left side of the extruding piece 3 is extruded and fitted with the inclined surface of the extruding block inside the first extruding frame 33.

[0047] As the rotating frame 113 rotates clockwise, the two extruding pieces 3 are rotated, the left side of the bottom extruding piece 3 is disengaged from the inclined surface of the extruding block inside the first extruding frame 33, and the left side of the top extruding piece 3 is engaged with the inclined surface of the extruding block inside the first extruding frame 33 and slides to the left. As the top extruding piece 3 moves to the left on the outer surface of the rotating frame 113, the top shifting piece 31 is moved to the left, and since the top shifting piece 31 is engaged with the top rotating piece 32, the rotating piece 32 is rotated when the top shifting piece 31 is moved to the left, and the top electromagnet 114 is rotated when the rotating piece 32 is rotated. As the rotating frame 113 rotates, the left side of the bottom extruding piece 3 is engaged with the inclined surface of the extruding block inside the second extruding frame 34 and slides to the right, and the bottom extruding piece 3 slides to the right to drive the bottom shifting piece 31 to slide, and the bottom shifting piece 31 slides to the right to drive the bottom rotating piece 32 to rotate, and the bottom rotating piece 32 rotates to drive the top electromagnet 114 to rotate. Since the shifting piece 31 is engaged with the rotating piece 32 through the cylindrical rod, when there is material between the shifting piece 31 and the rotating piece 32, it will not affect the rotation of the rotating piece 32 driven by the shifting piece 31. As the top electromagnet 114 and the bottom electromagnet 114 rotate intermittently, the electromagnet 114 can more comprehensively contact the metal impurities in the material, effectively adsorbing the impurities in the material and reducing the omission. During the rotation process, the electromagnet 114 can constantly change the contact position with the material, which helps to more comprehensively separate the impurities and avoid the accumulation of impurities on one side of the electromagnet 114.

[0048] Reference Figure 11 and Figure 12As shown, when the telescopic storage box 112 is moved to the left by the first guide frame 111, the top of the left front and rear ends of the telescopic storage box 112 will drive the first telescopic part 41 to move at the same time. At this time, when the first telescopic part 41 moves to the left, it will stretch the second telescopic part 43 to the left. When the telescopic storage box 112 moves to the left, it will also drive the elastic cloth 42 on the front and rear sides to stretch to the left at the same time. At this time, the electric push rod 4 is started, which drives the second telescopic part 43 to move upward. When the second telescopic part 43 moves upward, it will drive the moving end of the first telescopic part 41 to move at the same time. When the moving end of the first telescopic part 41 moves upward, it will drive the elastic cloth 42 to move upward at the same time. When the first telescopic part 41 moves upward, it can cover the upper surface of the telescopic storage box 112, prevent impurities from falling everywhere, help keep the working area clean, and reduce subsequent manual cleaning work.
