[0002] Scrap metal refers to metal fragments and debris discarded by the metallurgical industry and metal processing industry, as well as metal objects scrapped during equipment renewal, burned iron generated in the slag of thermal power plants and waste incineration plants, discarded home appliances, scrapped cars, construction waste, etc. After recycling, scrap metal is mainly used for smelting and converted into recycled metal, and some is used to produce machinery and equipment or parts, tools and civil appliances. Burned iron can also be recycled and reused in casting and forging, metal manufacturing and other fields. The recycling process of burned iron scrap metal mainly includes recovery and transportation, classification and sorting, crushing, cleaning and packaging, smelting and purification, classification and sorting. There are many types and materials of burned iron scrap metal, including iron, copper, aluminum and various alloy materials. When recycling, it is necessary to carry out fast and accurate classification and sorting to improve the efficiency of subsequent processing;

[0003] When sorting magnetic burnt iron scrap metal particles, magnetic separation is generally used for recovery. The magnetic metal is separated from the scrap metal by the magnetic adsorption principle. However, when a large number of metal particles are magnetically adsorbed, a large number of large magnetic metal particles adsorbed may carry non-magnetic metal particles mixed with small particles. During the magnetic separation process, the metal particles cannot be screened. When sorting magnetic burnt iron scrap metal particles, there is a problem that there is no design for screening particles of different sizes during the magnetic separation process. For this reason, the present application proposes a scrap metal recovery and sorting device. Utility Model Content

The operation of the lifting slide cylinder 23 makes the stabilizing frame 31 rise and fall vertically, which is conducive to the toggle rod 331 to descend to the inside of the second sieve plate 52, so as to disturb the metal particles and make the poured metal particles The granular material is in a loose state, and the rotating cylinder 25 is running to rotate the stabilizing frame 31, and the toggle rod 331 can stir the metal granular material; the flip assembly includes a stabilizing frame 31 connected to the rotating cylinder 25, a driving motor 32 installed inside the stabilizing frame 31, and a flip block 33 connected to the output shaft of the driving motor 32. The flip block 33 is respectively provided with a toggle rod 331 and an electromagnet 332 on the opposite surface. When the driving motor 32 is running, the flip block 33 is rotated 90 degrees in both directions, so that the electromagnet 332 faces the metal granular material in the second sieve plate 52. The electromagnet 332 is charged and generates a magnetic field, which can absorb magnetic metal particles; the screening mechanism includes a first sieve plate 51 installed between the opposite surfaces of the base frame 11, a second sieve plate 52 connected to the first sieve plate 51 in a split manner, a vibrator 53 installed on the bottom surface of the first sieve plate 51, a limiting component 4 installed on the inner wall of the base frame 11 and a connecting piece installed on the outer side of the first sieve plate 51. When the vibrator 53 is running, the first sieve plate 51 and the second sieve plate 52 vibrate, which can screen metal particles of different sizes inside the first sieve plate 51 and the second sieve plate 52.

[0026] In this embodiment, the limiting assembly 4 includes a stabilizing plate 41 installed on the base frame 11, a limiting rod 42 with one end passing through the top of the stabilizing plate 41, and a buffer spring 43 sleeved on the outside of the limiting rod 42.

The stabilizing plate 41 and the base frame 11 are combined by conventional methods. When the first sieve plate 51 is installed, the limiting ring 63 is sleeved on the outside of the limiting rod 42. The limiting ring 63 is limited by the limiting rod 42, so that the first sieve plate 51 is in a limited state.

[0027] In this embodiment, the top end of the limiting rod 42 is a "T"-shaped structure, the outer surface of the bottom end of the limiting rod 42 is provided with an external thread, and the inner surface of the bottom end of the stabilizing plate 41 is provided with a screw hole that cooperates with the bottom end of the limiting rod 42. The connection method between the limiting rod 42 and the stabilizing plate 41 is simple, which makes it easy to disassemble the limiting rod 42 and assemble the first sieve plate 51.

[0028] In this embodiment, the support frame 12 and the stabilizing frame 31 are frame structures, the base frame 11 is a "U"-shaped structure, and the outer surfaces of the first sieve plate 51 and the second sieve plate 52 are provided with discharge ports. When the vibrator 53 runs, the first sieve plate 51 and the second sieve plate 52 vibrate, and metal particles of different sizes inside the first sieve plate 51 and the second sieve plate 52 can be screened.

[0029] The working principle and use process of this utility model:

[0030] When sorting the magnetic burned iron scrap metal particles, the metal particles are poured into the second sieve plate 52, and the vibrator 53 is running, and the first sieve plate 51 and the second sieve plate 52 vibrate, so that the metal particles of different sizes in the first sieve plate 51 and the second sieve plate 52 can be screened.

[0031] At the same time, the lifting slide cylinder 23 operates, causing the stabilizing frame 31 to rise and fall vertically, and the toggle rod 331 to descend to the interior of the second sieve tray 52;

[0032] The rotating cylinder 25 is operated to rotate the stabilizing frame 31, and the toggle rod 331 can stir the metal granular material to make the poured metal granular material in a loose state;

[0033] The driving motor 32 is running to rotate the flip block 33 90 degrees forward and reverse, so that the electromagnet 332 faces the metal particles in the second sieve plate 52;

[0034] The electromagnet 332 is charged and generates a magnetic field, which can absorb magnetic metal particles. While adsorbing the metal particles, small metal particles can be screened out during the vibration process to prevent the magnetically attracted large metal particles from containing small metal particles.

[0035] In summary, when sorting magnetic burnt iron scrap metal particles, there is a design for screening particles of different sizes. While the electromagnet 332 adsorbs metal particles, the first sieve plate 51 and the second sieve plate 52 vibrate during the vibration process, which can screen metal particles of different sizes inside the first sieve plate 51 and the second sieve plate 52, thereby preventing small metal particles from being contained in the large metal particles attracted by the magnet.
