Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waste metal processing, and in particular to a waste metal sorting device. Background Technology
[0002] Scrap metal refers to various metal wastes generated during social production, consumption, and disposal. It mainly includes scraps and defective products from industrial production, scrapped machinery, transportation vehicles, electronic and electrical products, as well as construction and demolition waste and daily metal products. Its composition is complex, covering a variety of ferrous and non-ferrous metals such as iron, copper, aluminum, zinc, and stainless steel, and is often mixed with non-metallic impurities such as plastics, rubber, and oil.
[0003] Scrap metal sorting separates mixed metal scraps according to their material, specifications, magnetic properties, etc., avoiding performance degradation and resource waste caused by mixing different metals, thereby greatly improving resource utilization efficiency and economic benefits.
[0004] In existing technologies, due to the diverse forms of scrap metal and its high impurity content, most scrap metals are complex mixtures containing non-magnetic metals. This makes it easy for non-magnetic metals to mix with magnetic metals during sorting. Furthermore, bent or long scrap metals can accumulate and block sorting channels, hindering rapid sorting operations. At the same time, the mixing of non-magnetic metals with magnetic metals can lead to uneven stratification due to differences in the physical properties of the scrap metals during smelting, reducing the purity and performance of the metals. It can also generate harmful gases due to impurity reactions, affecting environmental protection and production safety. Utility Model Content

[0036] Example 1
[0037] Reference Figures 1 to 4 This is the first embodiment of the present utility model, which provides the following achievable effects:
[0038] 100 sorting boxes;
[0039] Crushing unit 200 is installed inside sorting box 100 and is used to crush waste metal. Screening unit 300 is installed inside sorting box 100 and is used to screen the crushed waste metal.
[0040] The lifting component 400 is installed inside the sorting box 100. The lifting component 400 cooperates with the screening unit 300 to lift the screening unit 300 upward. The magnetic suction component 500 is installed on the sorting box 100 and is used to attract waste metal with magnetic attraction effect.
[0041] In use, the crushing unit 200 can crush scrap metal and complex mixtures into smaller particles, making them easier to distinguish and improving the sorting and classification of scrap metal. The screening unit 300, together with the lifting component 400, accelerates the screening process of scrap metal through continuous vibration and prevents larger scrap metal particles from accumulating and clogging the screen holes. The magnetic component 500 can attract magnetic metals, allowing them to be quickly separated from non-magnetic metals, reducing manual intervention and improving sorting efficiency.
[0042] Example 2
[0043] Reference Figures 1 to 4 This is the second embodiment of the present invention, which differs from the previous embodiment in that...
[0044] The crushing unit 200 includes two crushing rollers 201, both of which are rotatably connected to the inner walls of both sides of the sorting box 100. One end of each crushing roller 201 moves through the sorting box 100 and is fixedly connected to a pulley 202. The two pulleys 202 are connected by a belt drive. A first motor 203 is fixedly connected to one side surface of the sorting box 100. The output end of the first motor 203 is fixedly connected to the other end of one of the crushing rollers 201. A feed pipe 204 is fixedly connected to the top surface of the sorting box 100.
[0045] The two crushing rollers 201 rotate in opposite directions through pulleys 202 and belt drive, and are driven by the first motor 203. They can shear and squeeze the scrap metal, efficiently crush metal materials of various shapes, and the feed pipe 204 facilitates the centralized introduction of materials. The double roller structure increases the crushing contact area and improves crushing efficiency and uniformity.
[0046] Specifically, the screening unit 300 includes multiple inclined panels 301, all of which are fixedly connected to the inner wall of the sorting box 100. The bottom surface of each of the multiple inclined panels 301 is fixedly connected to a telescopic rod 302, and a spring 303 is fixedly connected inside each of the multiple telescopic rods 302. The telescopic ends of the multiple telescopic rods 302 are jointly fixedly connected to a first screen plate 304, which is movably fitted against the inner wall of the sorting box 100.
[0047] The telescopic rod 302 and the spring 303 form an elastic vibration structure. When the crushed waste metal falls, the first screen plate 304 can accelerate the screening of the metal through vibration, while the spring 303 buffers and reduces the impact and avoids the screen holes of the first screen plate 304 from clogging. At the same time, the inclined plate 301 guides the material to fall to prevent it from accumulating on it.
[0048] Specifically, the lifting assembly 400 includes a rotating rod 401. One end of the rotating rod 401 is rotatably connected to the inner wall of one side of the sorting box 100, and the other end of the rotating rod 401 moves through the sorting box 100. A second motor 402 is fixedly connected to one side surface of the sorting box 100. The output end of the second motor 402 is fixedly connected to the other end of the rotating rod 401. Both sides of the rotating rod 401 are fixedly connected with protrusions 403.
[0049] The second motor 402 is started to drive the rotating rod 401 to rotate. The protrusions 403 on both sides continuously hit the bottom surface of the first screen plate 304, causing it to vibrate regularly. This effectively prevents the accumulation of scrap metal, which would cause the screen holes of the first screen plate 304 to become clogged, and improves the throughput of fine metal particles.
[0050] Specifically, the magnetic suction assembly 500 includes a second mesh plate 501, which is fixedly connected to one side surface of the sorting box 100. A side frame 502 is fixedly connected to one side surface of the sorting box 100. The side frame 502 matches the second mesh plate 501. An electromagnet 503 is fixedly connected to the top inner wall of the side frame 502.
[0051] When in use, the electromagnet 503 is activated, causing magnetic metals to be attracted to the second mesh plate 501, while non-magnetic metals continue to slide down, improving the device's sorting efficiency for scrap metals.
[0052] Example 3
[0053] Reference Figures 1 to 3This is the third embodiment of the present invention, which differs from the previous embodiment in that...
[0054] A vertical plate 3041 is fixedly connected to the bottom surface of the first screen plate 304, and a scraper 3042 is fixedly connected to the vertical plate 3041. The scraper 3042 is movably attached to the second screen plate 501.
[0055] When the first screen plate 304 vibrates, the vertical plate 3041 drives the scraper 3042 to move synchronously, continuously scraping the surface of the second screen plate 501, effectively preventing non-magnetic metal from accumulating on the screen plate and ensuring the adsorption effect on magnetic metal.
[0056] Specifically, a guide plate 101 is fixedly connected to one side surface of the sorting box 100, and the guide plate 101 is set at an angle.
[0057] The inclined surface of the guide plate 101 facilitates the sliding of the screened waste metal toward the magnetic attraction component 500, which makes it easier for the electromagnet 503 to attract the waste metal with magnetic attraction, thereby efficiently classifying it and facilitating subsequent sorting operations.
[0058] Specifically, a collection frame 102 is slidably connected to the sorting box 100, and a handle is fixedly connected to one side surface of the collection frame 102.
[0059] When in use, the handle makes it easy for operators to pull out or push the waste metal into the collection box 102. The waste metal that has been screened multiple times is concentrated in the collection box 102, which makes it easier to reduce the amount of waste metal that personnel need to sort and improve its sorting efficiency.
[0060] During use, scrap metal falls into the sorting box 100 through the feed pipe 204. The first motor 203 drives the right crushing roller 201 to rotate. Through the pulley 202 and belt drive, the left crushing roller 201 rotates synchronously in the opposite direction. The teeth on the surface of the two rollers shear and crush the scrap metal, processing it into fragments with uniform particle size. The crushed scrap metal falls onto the first screen plate 304. Particles smaller than the mesh size pass directly, while larger particles are temporarily stored on the screen surface. At this time, the second motor 402 drives the rotating rod 401 to rotate. The protrusion 403 continuously hits the bottom surface of the first screen plate 304. In conjunction with the telescopic rod 302 and the spring 303, elastic vibration is formed, thereby accelerating the passage of fine particles and preventing screen blockage, improving screening efficiency. The material slides to one side through the guide plate 101. The electromagnet 503 is activated to generate a strong magnetic field, which adsorbs ferromagnetic metal fragments. Non-magnetic materials continue to fall into the collection frame 102.
[0061] As the first mesh plate 304 vibrates, the vertical plate 3041 drives the scraper 3042 to move synchronously, scraping the larger magnetic metals and stuck non-magnetic metals adsorbed on the surface of the second mesh plate 501 towards the side frame 502, realizing automatic sorting. The operator can pull out the collection frame 102 by the handle for centralized processing. When it is necessary to clean magnetic materials, the power supply of the electromagnet 503 is cut off, the adsorbed metals automatically fall off, and then the side frame 502 can be opened.
[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
