[0002] Waste solid iron slag, commonly known as iron slag, iron residue or steel slag, is a solid waste generated in the industrial production process of steel smelting, casting, etc. The emission of this waste is huge. If it is not properly handled, it will cause serious pollution to the environment. Therefore, the resource recovery of waste solid iron slag is particularly important.

[0003] At present, during the use of the existing waste solid iron slag resource recovery and processing equipment, the iron slag is usually crushed and recovered by crushing rollers. However, the iron slag that has been crushed once may not be crushed well and needs to be crushed for the second time. However, if a secondary crushing is required, a screening is required first to screen out the iron slag with poor crushing effect before a secondary crushing can be performed. Therefore, it takes more time and effort, thereby reducing the resource recovery efficiency. Summary of the invention

It should be noted that the motor 4 is connected to the control switch with an external power supply, and one end of the screen plate 14 is mounted on the slag outlet 3, so that the larger iron slag is moved to the slag outlet 3 for discharge during the vibration process.

The transmission belt 13 can also drive the rotating rod 11 to rotate while the motor 4 drives the crushing rollers 5 to rotate. At this time, the eccentric block 12 will continuously strike the vibration plate 8. Since the vibration plate 8 and the screen plate 14 are connected in a rotating structure, the screen plate 14 will continue to vibrate and screen, thereby realizing energy-saving and efficient recycling of waste solid iron slag resources. After the screen plate 14 vibrates and screens, the collecting box 2 is used to collect the iron slag powder screened out by the screen plate 14, and the slag box 17 is used to collect the slag rolling down the screen plate 14. The movable block 21 at one end of the connecting rod 20 can drive the limit block 22 to contract by stepping on the connecting ring 23. At this time, the slag box 17 is pulled outward to make the first slider 18 slide out along the slide rail 16, so that the slag box 17 can be quickly disassembled, which is convenient for secondary processing of the screened iron slag.
