Description

Technical Field

[0001] The invention relates to the technical field of metal waste separation machinery for construction waste classification and treatment, and in particular to construction waste classification and treatment equipment. Background Art

[0002] Construction waste is the waste generated by the demolition and renovation of buildings during the construction process. Improper handling of construction waste will cause environmental pollution. Construction waste contains a large amount of recyclable materials. The construction waste can be crushed by professional waste treatment equipment, and then the waste fragments are transported through a conveyor belt sorting platform and sorted manually or mechanically. The recyclable materials in the construction waste fragments on the conveyor belt are preliminarily sorted. For metal materials such as steel and iron, the waste passing on the conveyor belt can be magnetically separated by electromagnets and transferred and stored separately.

[0003] With regard to the existing conveying platforms for sorting construction waste fragments, the waste may be stacked or pressed during transportation on the conveying platform. If the iron waste is located under bricks and stones during the adsorption of the electromagnet, the resistance to the separation of the iron waste will increase, thereby reducing the separation effect of the iron waste and resulting in a low separation rate. At the same time, after the iron waste is adsorbed from the conveying platform by the electromagnet, the electromagnet needs to be transferred, opened and closed through a complex lifting and transfer mechanism in conjunction with the PLC control system before the metal waste adsorbed by the electromagnet can be transferred to the metal storage hopper. The manufacturing cost and control difficulty of the equipment are high, which is not conducive to saving production costs. Summary of the invention

[0032] Specific usage and function: In the present invention, first, the construction waste is crushed by a crusher, and then the construction waste is evenly scattered on the conveyor belt of the waste conveying rack 1. When the waste conveying rack 1 is in operation, the construction waste is rotated from left to right, and the conveyor belt of the waste conveying rack 1 is reciprocated and pushed up by the cooperation of the vibration driving member 3 and the built-in rotating rack 4, so that the construction waste above the waste conveying rack 1 is shaken and turned over, and the slip ring control switch 902 is connected to the DC power supply, and then the slip ring control switch 902 is used to make a certain voltage between the two electrical slip rings 9, and the classification drive motor 6 drives the balance connecting rod 7 to rotate, and the balance connecting rod 7 is rotated to drive the two intermittent synchronous electromagnets 8 to intermittently surround the upper surface of the waste conveying rack 1 respectively.

As the classification drive motor 6 drives the intermittent synchronous electromagnet 8 to rotate continuously and brings the intermittent synchronous electromagnet 8 to the outside of the waste conveying rack 1, when the electrical connecting wheel 803 runs to the separation position of the two electrical slip rings 9, the two electrical connecting wheels 803 are disconnected from the circuit, causing the two intermittent synchronous electromagnets 8 to lose power, and the magnetic attraction of the intermittent synchronous electromagnet 8 disappears. In this state, the iron waste of the intermittent synchronous electromagnet 8 falls outward under its own gravity and the action of throwing off, and finally falls into the storage hopper 5 for collection, thereby completing the separation of the iron waste.
