Abstract
Description
Technical Field

[0002] With increasing environmental protection requirements, the technology for removing impurities from recycled aluminum is receiving more and more attention. Aluminum is a highly recyclable metal. By recycling aluminum, the demand for primary aluminum ore mining can be significantly reduced. This not only helps protect limited mineral resources, but also reduces the environmental impact of mining, such as land destruction and water pollution.
[0003] Existing waste removal devices for recycled aluminum include eddy current separators, which generate a high-frequency alternating strong magnetic field through a magnetic field generator. When the material enters the sorting zone, eddy currents are induced inside the aluminum metal under the action of the magnetic field. The magnetic field generated by the eddy currents is opposite to the original magnetic field, forming a repulsive force, thereby achieving repulsive screening. However, the matching conveyor belt has the problem of adhering debris and waste, which can easily lead to the crushing or accumulation of debris, reducing the service life of the equipment.
[0004] Therefore, we propose a device for removing impurities from recycled aluminum to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0025] Reference Figure 1-5 A recycled aluminum impurity removal device includes a housing 1, which serves as a support platform. A first conveyor belt 2 and a second conveyor belt 3 are horizontally mounted inside the housing 1, meaning both conveyor belts 2 and 3 are rotatably mounted on the housing 1. The first conveyor belt 2 and the second conveyor belt 3 are arranged parallel to each other. The first conveyor belt 2 is equipped with a cleaning mechanism, and the second conveyor belt 3 has a feeding mechanism at its bottom.
[0026] As a technical optimization of this utility model, the first conveyor belt 2 is driven by two rollers. One end of the device housing 1 is provided with a feeding hopper 4 for pouring materials in. The other end of the device housing 1 is provided with a discharge hopper 5 for discharging materials. The roller of the first conveyor belt 2 near the discharge hopper 5 is equipped with an eccentrically rotating magnetic field generator. The other roller is a power roller, that is, a drive motor for driving the roller rotation is installed on the device housing 1.
[0027] For the above example, those skilled in the art should know that when implementing the above technical solution, the material poured into this device is the crushed material.
[0028] For the above examples, those skilled in the art should know that when implementing the above technical solutions, this device uses a magnetic field to screen aluminum metal, and its main functions include those of existing eddy current separators.
[0029] Regarding the above example, those skilled in the art should understand that, in implementing the above technical solution, the working principle of the magnetic field generator inside the roller is based on the interaction of electromagnetic induction and magnetic fields. When the equipment is started, the magnetic field generator generates a high-frequency alternating strong magnetic field. After the material enters the sorting zone, eddy currents are induced inside the aluminum metal under the action of the magnetic field. The magnetic field generated by the eddy currents is opposite in direction to the original magnetic field, forming a repulsive force, thereby achieving repulsive screening. The magnitude of the repulsive force depends on the conductivity and density of the material. The stronger the conductivity and the greater the density of the metal material, the greater the repulsive force it experiences, and thus it is thrown further away.
[0030] As a technical optimization of this utility model, a guide plate 10 is fixed at one end of the device housing 1 near the discharge hopper 5. The guide plate 10 is located between the first conveyor belt 2 and the discharge hopper 5, and an inverted V-shaped baffle 11 is provided at the bottom of the guide plate 10. The guide plate 10 and the inverted V-shaped baffle 11 play an effective guiding role.
[0031] As a technical optimization of this utility model, the second transmission belt 3 further includes two pairs of rotating wheels 6, which are connected by two transmission belts 7. One of the rotating wheels 6 is driven by a rotating motor. That is, there is a gap between the two transmission belts 7, and the two transmission belts 7 can be driven to rotate synchronously.
[0032] For the above example, those skilled in the art should know that when implementing the above technical solution, the transmission belt 7 is made of rubber or other flexible belt material, and it is necessary to ensure that it has sufficient tensile strength.
[0033] As a technical optimization of this utility model, several fixed seats 8 are evenly arranged around the outer sides of the two transmission belts 7. Rollers 9 are rotatably mounted on the fixed seats 8, and the rollers 9 are set to abut against the bottom of the first transmission belt 2. The abutment of the rollers 9 can stabilize the first transmission belt 2, and the rollers 9 will not affect the rotation of the first transmission belt 2.
[0034] As an optimized technical solution of this utility model, the cleaning mechanism includes a plurality of strip-shaped brushes 12, the two ends of which are fixedly connected to two transmission belts 7 respectively, and the plurality of strip-shaped brushes 12 are evenly arranged on the two transmission belts 7. The transmission direction of the first transmission belt 2 of this device is opposite to the transmission direction of the second transmission belt 3, and the rotation speed of the second transmission belt 3 is less than the rotation speed of the first transmission belt 2. When the two transmission belts 7 on the second transmission belt 3 rotate, they can drive the plurality of strip-shaped brushes 12 to clean the bottom of the first transmission belt 2.
[0035] As an optimized technical solution of this utility model, the feeding mechanism includes a third transmission belt 13 disposed at the bottom of the device housing 1. Both ends of the third transmission belt 13 are equipped with rotating shafts. A first pulley 14 is coaxially fixed to one rotating wheel 6, and a second pulley 15 is coaxially fixed to one rotating shaft of the third transmission belt 13. The first pulley 14 and the second pulley 15 are connected by a transmission belt. The rotation of the rotating wheel 6 of the second transmission belt 13 drives the first pulley 14 to rotate, and the rotation of the first pulley 14 drives the second pulley 15 to rotate, thereby driving the third transmission belt 13 to rotate. The second transmission belt 13 and the third transmission belt 13 rotate in the same direction. The third transmission belt 13 can discharge material to the end of the device housing 1 near the feeding hopper 4.
[0036] For the above example, those skilled in the art should know that when implementing the above technical solution, the bottom of the device housing 1 is provided with a material inlet corresponding to the third conveyor belt 13, and a box can be set at the material inlet to receive the material.
[0037] In this invention, the working principle of the device is as follows:
[0038] The material can be conveyed to the top of the feeding hopper 4 through the existing material conveying device, and then fall from the feeding hopper 4 onto the first conveyor belt 2. The first conveyor belt 2 conveys the material, and then the aluminum metal material is discharged from the discharge hopper 5 through vortex screening. A box can be placed below the discharge hopper 5 to receive and collect the recycled aluminum material after impurity removal and separation. The screened material continues to be conveyed to the bottom through the first conveyor belt 2. The guide plate 10 and the inverted V-shaped baffle 11 play an effective role in guiding the material. Since there is a gap between the two drive belts 7 of the second conveyor belt 3, and there is also a gap between the several strip brushes 12, the material can fall onto the third conveyor belt 13 through the gap. In the above process, the transmission direction of the first conveyor belt 2 is opposite to that of the second conveyor belt 3, and the rotation speed of the second conveyor belt 3 is less than that of the first conveyor belt 2. When the two transmission belts 7 on the second conveyor belt 3 rotate, they drive several strip-shaped brushes 12 to move. The moving speed of the strip-shaped brushes 12 is less than that of the first conveyor belt 2. At this time, the strip-shaped brushes 12 can sweep the obstructing waste material that is adhered and carried to the bottom onto the third conveyor belt 13, effectively ensuring the normal operation of the first conveyor belt 2, ensuring the impurity removal operation, and effectively preventing the crushing or adhesion and accumulation of broken material, thus effectively improving the service life of the equipment. Afterwards, the rotation of the roller 6 of the second conveyor belt 3 can drive the rotation of the first pulley 14, and the rotation of the first pulley 14 can drive the rotation of the second pulley 15, which in turn drives the rotation of the third conveyor belt 13. The rotation directions of the second conveyor belt 3 and the third conveyor belt 13 are the same. The third conveyor belt 13 can discharge the screened material, and the discharged material is easy to be screened and removed multiple times, that is, poured back into the feeding hopper 4.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
