The construction waste pieces are put into the primary crusher 200 from the first feed port, and the primary crusher 200 crushes the construction waste pieces. The primary crusher 200 preferably uses a jaw crusher, and has high crushing efficiency for construction waste, so that the reinforcing steel bars in the concrete blocks can be easily peeled off.
After crushing, small building rubbish falls on the first conveyer belt 300 from the first discharge gate, and in the conveying process of the first conveyer belt 300, the deironing device 400 above the first conveyer belt 300 adsorbs and transfers the mixed magnetic metal in the building rubbish, so that the screening of the building rubbish is realized, and different retreatment and utilization are carried out on different types of building rubbish. The magnetic metal is iron, nickel, cobalt, or the like, and is attracted to the magnet. Since steel bars are commonly used as tensile frameworks in buildings, most of the metals in the construction waste are magnetic metals such as steel bars.
It can be understood that the iron removing device 400 includes an electromagnet 410 and a cleaning assembly 420, the electromagnet 410 is disposed above the conveying path of the first conveyor belt 300, the cleaning assembly 420 has a cleaning belt 421, the cleaning belt 421 is disposed around the electromagnet 410 and is movable, and the moving path of the cleaning belt 421 is located between the electromagnet 410 and the first conveyor belt 300, and the moving path of the cleaning belt 421 and the conveying path of the first conveyor belt 300 are not parallel to each other.
Referring to fig. 2, construction waste mixed with magnetic metal passes through the iron removing device 400 while being transported on the first conveyor belt 300. When the magnetic metal is located below the electromagnet 410, the magnetic metal is attracted by the electromagnet 410, and moves toward the direction of the electromagnet 410 until being blocked by the cleaning belt 421 between the electromagnet 410 and the first conveyor belt 300, so that the magnetic metal is attached to the cleaning belt 421. Meanwhile, the cleaning belt 421 is also in a moving state, and the moving path of the cleaning belt 421 is not parallel to the conveying path of the first conveying belt 300, so that the magnetic metal is separated from the upper part of the first conveying belt 300 by the cleaning belt 421, and the magnetic metal naturally falls off under the action of gravity after the magnetic metal moves to the area with weak magnetism of the electromagnet 410, thereby realizing the separation of the magnetic metal in the construction waste.
Referring to fig. 3, it may be understood that the cleaning assembly 420 includes a driving roller 422, a first driving device 423 and a plurality of driving rollers 424, the driving roller 422 and the driving rollers 424 are parallel to each other and are all disposed around the electromagnet 410, the cleaning belt 421 is sleeved on the driving roller 422 and the driving rollers 424, and the first driving device 423 is in driving connection with the driving roller 422 to drive the driving roller 422 to rotate, so as to drive the cleaning belt 421 to move.
The first driving device 423 drives the driving roller 422 to rotate, and drives the cleaning belt 421 to move by the friction force between the cleaning belt 421 and the driving roller 422. The first drive 423 may be powered by an electric motor, which is preferably in driving engagement with the drive roll 422 using pulleys and belts. The plurality of driving rollers 424 serve to support the cleaning belt 421 and to guide the change of the moving direction of the cleaning belt 421.

If the attraction force between the magnetic metal and the electromagnet 410 is large, the friction force between the cleaning belt 421 and the magnetic metal is insufficient to drive the magnetic metal to move, so the barrier 425 is required to push the magnetic metal away from the strong magnetic area of the electromagnet 410 and move the magnetic metal to the weak magnetic area until the gravity of the magnetic metal is larger than the attraction force, and the magnetic metal naturally drops off.
It will be appreciated that a heat dissipation fan 411 is also provided on one side of the electromagnet 410. Since the electromagnet 410 is supplied with a variable current to generate a magnetic field, a large amount of heat can be generated by a larger current, and the heat dissipation fan 411 can perform air cooling heat dissipation for the electromagnet 410, so that the service life of the electromagnet 410 is prolonged.
