A roller for driving the garbage to move by rotating so as to sieve the materials is arranged in the sieving bin 81. The roller can drive the garbage to move by rotating continuously, so that the effects of stirring and refining are achieved, and the garbage can be screened conveniently.

As shown in fig. 9, the eddy current separator 10 includes a conveyor belt 101 for conveying the non-magnetic metallic waste output from the magnetic separator 9, a magnetic drum 102 vertically arranged in the conveying direction of the conveyor belt 101 and surrounding the output end of the magnetic separator 9, and a fifth driving mechanism 103 for driving the magnetic drum 102 to rotate in the circumferential direction to generate an alternating magnetic field in the inner cavity of the magnetic drum 102, and the output end of the conveyor belt 101 is provided with a seventh bin 104 for collecting non-ferrous metals and an eighth bin 105 for collecting insulating waste. The conveyer belt is installed through the cooperation of conveyer belt drive roll and conveyer belt driven voller. The magnetic separator 9 of the magnetic separation device comprises a magnetic roller 91 and a ninth bin which is positioned below the magnetic roller 91 and used for collecting magnetic metal garbage, the magnetic roller 91 and a driving roller of a conveying belt are in transmission connection with a sixth driving mechanism 106 through a transmission belt, the sixth driving mechanism 106 drives the magnetic roller 91 and the driving roller of the conveying belt to rotate, so that the magnetic roller 91 absorbs the magnetic metal garbage in the garbage and drives the magnetic metal garbage to fall into the ninth bin, and the garbage of non-magnetic metal falls onto the conveying belt 101 and is conveyed into the magnetic cylinder 102.

In the eddy current sorting apparatus 10 of the present embodiment, the fifth driving mechanism 103 drives the magnetic cylinder 102 to rotate in the circumferential direction, and an alternating magnetic field is generated in the inner cavity of the magnetic cylinder 102. When the conveying belt 101 conveys the garbage through the alternating magnetic field, since the nonferrous metals in the garbage have conductivity, eddy current is induced in the nonferrous metals, and the eddy current generates an induced magnetic field. Because the direction of the induction magnetic field is opposite to that of the alternating magnetic field, the nonferrous metals jump upwards due to the repulsion action and simultaneously continue to move along the conveying direction under the action of inertia. The non-ferrous metal then falls under gravity into the non-ferrous metal fall path and finally into the seventh bin 104. Since the non-metal in the garbage has no conductivity, the non-metal is conveyed along the conveying direction, and then falls down from the output end of the conveying belt 101 to the non-metal falling channel under the action of gravity, and finally falls down to the eighth bunker 105. Nonferrous metals are collected through the seventh bunker 104, and wastes of insulating materials having no conductivity are collected through the eighth bunker 105, so that the nonferrous metal wastes and the non-metallic wastes having insulation among the remaining wastes are classified.

The inner wall surface of the magnetic cylinder 102 is provided with magnetic source bodies distributed along the axial direction of the magnetic cylinder 102, an even number of magnetic source bodies are uniformly distributed along the circumferential direction of the magnetic cylinder 102, two magnetic source bodies positioned on the same radial direction of the magnetic cylinder 102 form a magnetic source body group, and the directions of magnetic fields generated by two adjacent magnetic source body groups are opposite. The directions of the magnetic fields generated by two adjacent magnetic source body groups are opposite, and when the magnetic cylinder 102 rotates along the circumferential direction, the directions of the magnetic fields generated by the plurality of magnetic source body groups are alternately changed, namely, an alternating magnetic field is generated. Alternatively, the magnetic source body is made of permanent magnets. The polarity directions of two magnetic source bodies in the same magnetic source body group are opposite, and the polarity directions of two magnetic source bodies adjacent to each other in the circumferential direction of the magnetic cylinder 102 are opposite. The polarity directions of two magnetic source bodies in the same magnetic source body group are opposite, and the polarity directions of two magnetic source bodies adjacent to each other in the circumferential direction of the magnetic cylinder 102 are opposite, so that the directions of magnetic fields generated by two adjacent magnetic source body groups are opposite. The polar direction refers to a direction in which the N pole points to the S pole or a direction in which the S pole points to the N pole. In this embodiment, the magnetic source body includes at least two magnetic source segments spaced apart from each other in the axial direction of the magnetic cylinder 102, and the polarity directions of two adjacent magnetic source segments are the same. The magnetic source body is not limited to the single-stage type, but may be multi-stage type, that is, the magnetic source body includes at least two magnetic source segments spaced along the axial direction of the magnetic cylinder 102, and the polarity directions of two adjacent magnetic source segments are the same. When the magnetic cylinder 102 rotates in the circumferential direction, at least two magnetic source segments arranged at intervals in the axial direction of the magnetic cylinder 102 may generate a multistage alternating magnetic field. When the nonferrous metal passes through the multistage alternating magnetic field, the jumping speed of the nonferrous metal is faster, the jumping distance is longer, and the nonferrous metal and the nonmetal can be screened.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
