Description

Technical Field

[0001] This invention relates to the field of eddy current sorting, and particularly to an eddy current sorting line. Background Technology

[0002] Eddy current separators can effectively and automatically separate non-metallic materials from non-ferrous metals. They are widely used in the recycling of various non-ferrous metals such as copper and aluminum from municipal solid waste after crushing by crushing equipment, scrap cars after being shredded by shredders, and material processing and sorting in the environmental protection industry.

[0003] Current eddy current separators suffer from several drawbacks. Excessive gap between the magnetic roller and the outer ring results in weak magnetic strength, poor separation efficiency, and an inability to separate fine metal materials. Furthermore, operator adjustments are difficult, requiring repeated adjustments to achieve the minimum gap, leading to a high workload and frequent downtime. Additionally, the angle of the eddy current separator's dividing plate is not easily adjustable, making it impossible to obtain the optimal separation angle based on the characteristics of different metals or materials of different sizes. This results in metal materials mixing with non-metallic materials, leading to poor screening of some materials. Summary of the Invention

[0004] To address one or more of the above problems, the present invention provides an eddy current sorting line.

[0005] According to one aspect of the present invention, the eddy current sorting line includes a vibrating feeder, a frame with a box structure, and an eddy current separator and a material distribution unit fixed in the frame;

The lower surface of the right end of the frame is provided with a non-metallic material outlet and a metallic material outlet from left to right.

[0007] The double eccentric eddy current magnetic roller of the eddy current separator is located directly above the non-metallic material outlet. The double eccentric eddy current magnetic roller includes a fiberglass cylinder, an eccentric magnetic core, an eccentric ring, and an adjusting locking block. High-speed bearings are fixed to both ends of the eccentric magnetic core with bushings. Large bearings are installed inside both ends of the fiberglass cylinder. The high-speed bearing is fixed to the inner wall of the eccentric ring with bushings, and its outer wall bushings are connected to the large bearing hub of the large bearing. The adjusting handle is installed at the lower end of the side wall of the large bearing hub. Rotating the adjusting handle can quickly bring the inner wall of the fiberglass cylinder and the eccentric magnetic core to the minimum gap position. One end of the adjusting locking block is threaded to fix the eccentric magnetic core, and the other end is adjustable and threaded to fix the large bearing hub, thus fixing the large bearing hub and the eccentric ring. Rotating the entire double eccentric eddy current magnetic roller brings the optimal magnetic separation position to the working position of the eddy current separator.

[0050] The beneficial effects of this invention are as follows: First, it features a double eccentric eddy current magnetic roller 04, which makes it easy to adjust to the optimal magnetic separation position, resulting in better magnetic separation and the ability to separate fine non-ferrous metal objects. Second, the dedicated adjustment handle, set at the optimal adjustment position, provides good torque, is simple to operate, labor-saving, safe, and reliable, and avoids damage to the eddy current magnetic roller caused by irregular adjustments by operators. The adjusting locking block can quickly position and cover a larger fixed position, with high installation accuracy and reliable locking to prevent position changes. Third, the angle and spacing of the material separating plate 1 are adjustable, enabling the screening of various materials with good material screening effect.

The flat-head screw passes through the countersunk hole of the fiberglass cylinder 1 and is screwed into the threaded hole of the large bearing ring 72, and the end of the fiberglass cylinder 1 abuts against the shoulder. Its beneficial effects are: the shoulder can provide good axial positioning for the fiberglass cylinder 1, which facilitates the improvement of the installation accuracy of the fiberglass cylinder 1. At the same time, the connection structure of the flat-head screw and the countersunk hole can optimize the product volume.

Its advantages are: the machined locking groove improves the flatness of the mounting surface, allowing for higher installation accuracy of the adjusting locking block 4 and preventing misalignment caused by poor flatness. Furthermore, the locking groove allows the adjusting locking block 4 to be internally mounted, reducing the overall size of the equipment.

[0071] Preferably, the outer side of the large bearing hub 71 is provided with two symmetrically arranged second arc grooves 712.

The far end of the angle adjusting screw 065 passes through another adjusting plate 0632 and is screwed into an angle adjusting nut 062. Rotating the angle adjusting screw 065 allows the sliding guide rod 064 to move longitudinally in the longitudinal guide hole 0630 and slide in the vertical guide hole 0322. The tangential force of the sliding guide rod 4 acts on the vertical end plate 0320, causing the material distribution plate 031 to rotate by a set angle. Its beneficial effects are as follows: First, by simply rotating the angle adjusting screw 065, the sliding guide rod 064 can move linearly within the longitudinal guide hole 0630, while simultaneously sliding within the vertical guide hole 0322. Its tangential force acts on the vertical end plate 0320, thus changing the angle of the material distribution plate 031. Angle adjustment is simple and maintenance is convenient.
