Description

Technical Field

[0001] This utility model relates to the field of metal scrap recycling technology, specifically a metal scrap recycling and impurity removal device. Background Technology

[0002] Metal scraps are small pieces or powdery substances produced during the processing, cutting, grinding, and crushing of metals. Their shape and size vary depending on the processing method and may be in the form of flakes, granules, or filaments. These scraps may come from various metal materials such as steel, aluminum, and copper, and are commonly found in machining, metallurgy, and scrap metal processing. Metal scraps have the general properties of metals, such as electrical and thermal conductivity, but their altered physical form requires attention to safety during storage, transportation, and handling to avoid dangers caused by accumulation or friction. At the same time, they can be recycled to achieve resource recycling. Traditional methods of metal scrap recycling are rather crude, typically involving simply piling up the collected scraps and then performing basic screening. This approach has several problems. First, metal scraps often contain non-metallic impurities such as plastics, rubber, and sand. Without effective separation, these impurities severely affect the quality of the recycled metal and its reuse value. Second, traditional screening methods are inefficient, relying heavily on manual operation, which not only consumes significant manpower and time but also makes it difficult to guarantee screening accuracy. Furthermore, the recycling process generates dust, polluting the working environment and posing health risks to operators. Therefore, the development of a highly efficient, precise, and environmentally friendly metal scrap recycling and impurity removal device is urgently needed. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0017] Reference Figures 1 to 4In this embodiment of the utility model, a metal scrap recycling and impurity removal device includes: a recycling box 1, a feeding port 2 at the top of the recycling box 1, and a first feeding ramp 3 below the feeding port 2. When the device is working, metal scrap containing various impurities enters from the feeding port 2 and slides down to a magnetic separation mechanism inside the recycling box 1 under the guidance of the first feeding ramp 3. The magnetic separation mechanism includes multiple electromagnetic coils 4 installed on the inner wall of the recycling box 1 and a second feeding ramp 5 below the electromagnetic coils 4. A conveyor belt 6 is provided below the second feeding ramp 5. The conveyor belt 6 is driven by an internal drive motor. The multiple electromagnetic coils 4 generate a magnetic field when energized, which attracts the ferromagnetic metal scrap. The remaining scrap falls onto the conveyor belt 6 under the guidance of the first feeding ramp 3 and is then transported to a vibrating screening mechanism by the drive motor.

[0018] The vibrating screening mechanism includes an inclined screen 7 and a vibrating motor 8 installed below the inclined screen 7. The inclined screen 7 is set at an inclination, and the lower end of the inclined screen 7 is connected to the discharge port opened above the metal scrap collection bin 10 on one side of the recycling box 1. A third feeding inclined plate 9 is provided below the vibrating screening mechanism. The vibrating motor 8 drives the inclined screen 7 to vibrate, so that the scrap moves on the inclined screen 7. Smaller scrap and impurities pass through the mesh and fall onto the third feeding inclined plate 9 to be separated, while larger metal scraps enter the metal scrap collection bin 10 through the discharge port along the lower end of the inclined screen 7.

[0019] After the electromagnetic coil 4 is de-energized, the ferromagnetic metal fragments adsorbed by magnetic attraction fall into the metal fragment collection bin 10 through the first metal conveying pipe 12 along the second feeding inclined plate 5. The metal fragment collection bin 10 is equipped with a compression mechanism, which includes a bracket 16, a hydraulic cylinder and a pressure plate 17. The pressure plate 17 is connected to the piston rod of the hydraulic cylinder. A pull plate 18 is inserted into the side of the metal fragment collection bin 10. The metal fragments falling into the metal fragment collection bin 10 are compressed by the hydraulic cylinder of the compression mechanism pushing the pressure plate 17, which facilitates storage and transportation. The pull plate 18 can be used to remove the compressed metal block.

[0020] A vortex sorting mechanism is provided on one side of the recycling box 1. The vortex sorting mechanism includes a sorting box 11, a rotating magnetic field generator 13 is provided inside the sorting box 11, a non-metallic outlet 14 is provided on one side of the sorting box 11, and a second metal conveying pipe 15 is provided on the other side. A first metal conveying pipe 12 is fixedly connected between the second feeding inclined plate 5 and the metal debris collection bin 10. Non-ferromagnetic metal debris that does not enter the metal debris collection bin 10 through the vibration screening mechanism will enter the sorting box 11 of the vortex sorting mechanism through the pipe. The rotating magnetic field generator 13 generates a rotating magnetic field, causing the non-ferromagnetic metal to deviate from its original trajectory under the action of eddy current force and be conveyed from the second metal conveying pipe 15 to the metal debris collection bin 10. The non-metallic material is discharged from the non-metallic outlet 14.

[0021] The inner wall of the sorting box 11 is provided with a wear-resistant layer, which is made of ceramic material. This design can extend the service life of the equipment. At the same time, the surface of the conveyor belt 6 is provided with anti-slip protrusions to ensure stable conveying of debris. The inclined screen 7 is made of stainless steel, and the mesh size of the inclined screen 7 gradually decreases from the feed end to the discharge end, which can achieve better screening effect.

[0022] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0023] The working principle of this utility model is as follows: Metal scraps enter from the feed inlet 2, slide down the first discharge inclined plate 3 to the magnetic separation mechanism, the electromagnetic coil 4 is energized to attract ferromagnetic metal scraps, the remaining scraps are guided by the first discharge inclined plate 3 to the conveyor belt 6, the drive motor drives the conveyor belt 6 to send them to the vibrating screening mechanism; the vibrating motor 8 causes the inclined screen 7 to vibrate, small scraps and impurities fall through the mesh to the third discharge inclined plate 9 and are separated, and large metal scraps enter the metal scrap collection bin 10 from the lower end of the inclined screen 7 discharge port; after the electromagnetic coil 4 is de-energized, the attracted ferromagnetic metal scraps fall along the second discharge inclined plate 5 through the first metal conveying pipe 12 into the... Metal scrap collection bin 10; metal scrap entering the metal scrap collection bin 10 is compressed by the pressure plate 17 pushed by the hydraulic cylinder, and the compressed metal block can be removed by the pull plate 18; non-ferromagnetic metal scrap that does not enter the metal scrap collection bin 10 enters the sorting box 11 of the eddy current sorting mechanism, and the rotating magnetic field generator 13 generates a magnetic field to make the non-ferromagnetic metal enter the metal scrap collection bin 10 through the second metal conveying pipe 15, and the non-metallic material is discharged from the non-metallic outlet 14. Throughout the process, the wear-resistant ceramic layer on the inner wall of the sorting box 11 ensures the durability of the equipment, the anti-slip protrusions of the conveyor belt 6 ensure stable conveying, and the gradient mesh of the inclined screen 7 achieves efficient screening.
