Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel scrap recycling, in particular to a steel scrap recycling system. BACKGROUND

[0002] Scrap steel refers to steel scrap (such as cut edges, cut heads, etc.) in the production process of steel plants and steel materials in scrapped equipment and components after use, which is called scrap steel if the composition is steel; it is called scrap iron if the composition is pig iron, and it is collectively called scrap steel.

[0003] Scrap steel recycling is a treatment method that utilizes the magnetic differences of various substances in solid waste to sort in non-uniform magnetic sound. Magnetic separation is the most effective method for sorting iron-based metals. In the current recycling method, solid waste is input into a magnetic separator, and magnetic particles are magnetized under the action of non-uniform magnetic sound, thereby being attracted by the magnetic field force, so that the magnetic particles are sucked into the cylinder and enter the discharge end with the cylinder; non-magnetic particles remain in the waste due to the small magnetic field force.

[0004] However, in the process of separating magnetic particles from non-magnetic particles, the magnetic particles and non-magnetic particles are mixed together in the process of magnetic separation of the equipment, and then the magnetic and non-magnetic particles are screened from the mixed steel scrap. When screening, the equipment will vibrate mechanically, and in the process of separation, the magnetic particles will rub with the non-magnetic particles. In the process of discharging from the discharge port, the non-magnetic particles will carry part of the magnetic particles out of the discharge port together, resulting in the mixing of magnetic particles in the non-magnetic particles during the magnetic separation of the steel scrap. Subsequently, the magnetic particles and non-magnetic particles mixed with the steel scrap are conveyed to the next step by the conveying belt, but the magnetic impurities and non-magnetic impurities are mixed together, resulting in poor screening effect of the final magnetic and non-magnetic particles.
