Description
Technical Field
The invention relates to the technical field of separation and screening of metal and nonmetal materials, in particular to chute type eddy current separation equipment for separating secondary resources from metal and nonmetal materials.
Background
It is known from the law of electromagnetic induction that a conductor generates an induced current in a changing magnetic field, whereas the biot-savart law states that a magnetic field acts on a current carrying conductor or coil. In the alternating magnetic field, the metal conductor can excite to generate eddy current, the magnetic field generated by the eddy current interacts with the external magnetic field to enable the metal conductor to be subjected to the action of the eddy current, and the nonconductors cannot generate the influence. By utilizing the principle, the equipment for separating the conductor from the non-conductor can be designed, namely the eddy current separator is also called an eddy current separation device. In the eddy current separation process, the material separation mode is direct, secondary waste is not generated, and the eddy current separation method has higher application value.
An existing eddy current separator is an eddy current separator device disclosed in Chinese patent CN109433414B, and comprises a frame, wherein a front side conveyor rotating wheel and a rear side conveyor rotating wheel are rotatably assembled on the frame, a material conveying belt is wound on the front side conveyor rotating wheel and the rear side conveyor rotating wheel, an eddy current magnetic roller is arranged in one conveyor rotating wheel, and the rotating direction of the eddy current magnetic roller is opposite to that of the corresponding conveyor rotating wheel.
When the eddy current separator works, the separated materials are conveyed along with the material conveying belt, one end of the material conveying belt is thrown off, and before throwing off, conductors in the separated materials are pushed away from the belt surface under the action of eddy current force, and nonconductors in the separated materials are not influenced basically, so that effective separation of the conductors and the nonconductors is realized. The existing eddy current separator has the following problems: the eddy current magnetic roller is mostly made of permanent magnets, the physical upper limit of the magnetic field intensity of the permanent magnets is determined by the material properties, the magnetic field distribution characteristics of the surfaces of the permanent magnets are determined, and the closer the material is to the magnetic poles of the magnets, the larger the magnetic field gradient is, and the larger the material is influenced by the magnetic field. Therefore, the distance between the material and the magnet should be reduced as much as possible to strengthen the effect of eddy current force, however, in the prior art, the eddy current magnetic roller is located inside one of the conveyor rotating wheels, the effect of the conveyor rotating wheels and the material conveying belt is to realize effective conveying of the material through self action, so the conveyor rotating wheels and the material conveying belt need to have certain strength (namely, the conveyor rotating wheels and the material conveying belt need to have certain thickness), the conveyor rotating wheels and the material conveying belt need to have certain thickness, in addition, in order to ensure stable operation of the device, certain clearance needs to be reserved between the two moving parts of the eddy current magnetic roller and the conveyor rotating wheels, and finally, a larger clearance is reserved between the eddy current magnetic roller and the material to be separated on the material conveying belt, so that when the material is separated, the gradient of the magnetic field actually influencing the material is lower, namely, the belt eddy current separator is only suitable for processing coarse (centimeter level) material separation, and is difficult to realize material separation of coarse grains (millimeter level).
However, in the actual solid waste recycling process, the problem of separation of fine-grain metal materials is always faced, even coarse-grain metal materials are mixed with a lot of fine-grain metal materials, and the current main-stream fine-grain separation process is the operations of salt washing, shaking table, air separation and the like, but the related workers have the problems of secondary pollution, poor separation effect and the like.
