Description

Technical Field

[0001] The utility model mainly relates to the technical field of waste aluminum recycling, and specifically relates to a magnetic separation device for waste aluminum recycling. Background Technique

[0002] Aluminum is a commonly used metal in industry, with good corrosion resistance and oxidation resistance. Therefore, waste aluminum also has extremely high recycling value.

[0003] Since waste aluminum contains various impurity metals, it is necessary to remove the impurity metals during the recycling process. For iron impurities in waste aluminum recycling, the traditional method is to use an electromagnet to adsorb the iron impurities in the waste aluminum, and then move the electromagnet to other positions, and then cut off the power to collect the iron impurities. However, this process requires continuous adsorption, transfer and other steps, resulting in slow magnetic adsorption efficiency. Therefore, a new magnetic separation device for waste aluminum recycling is needed. Summary of the Utility Model

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution significantly different from the existing technology. It mainly provides a magnetic separation device for waste aluminum recycling to solve the technical problem that the traditional magnetic adsorption method needs to continuously perform steps such as adsorption and transfer to remove iron impurities in waste aluminum with slow efficiency as mentioned in the above background technique.

Telescopic members in rotational contact with the contact switch are installed in the grooves. Collection grooves communicating with the circular grooves are opened on both the left and right sides of the front surface of the inclined block. The groove located below the semi-circular groove is located between the two collection grooves.

[0007] Preferably, the rotating member includes a rotating rod driven by a servo motor to rotate clockwise. The rotating rod is rotatably connected in the circular hole.

[0023] Please refer specifically to the attached Figures 1-3 , a magnetic separation device for waste aluminum recycling, including an inclined block 1. A semi-circular groove 9 is opened at the center of the inclined surface of the inclined block 1. Circular holes are opened on both the front and rear sides of the semi-circular groove 9. A rotating rod 5 driven by a servo motor to rotate clockwise is rotatably connected in the circular holes. A plurality of rotation frames 3 arranged annularly and equidistantly are installed on the annular surface of the rotating rod 5. The rotation frames 3 are slidably connected in the semi-circular groove 9. Then, a plurality of electromagnets 8 for adsorbing iron impurities are installed in the rotation frames 3. A rectangular groove is opened on the surface of the rotation frame 3 in contact with the semi-circular groove 9. A contact switch 4 for controlling the opening and closing of the electromagnet 8 is installed in the rectangular groove.

[0024] Grooves are opened on both the lower side of the annular inner part of the semi-circular groove 9 and on one side of the semi-circular groove 9 close to the top of the inclined surface of the inclined block 1. A slant plate 12 is slidably connected in the grooves. One end of the slant plate 12 away from the grooves is in contact with the contact switch 4. An elastic member 11 is installed at one end of the slant plate 12 in the grooves. The elastic member 11 is a spring. The elastic member 11 is in a compressed state. The end of the elastic member 11 away from the slant plate 12 is installed in the grooves. Collection grooves 10 communicating with the circular groove 9 are opened on both the left and right sides of the front surface of the inclined block 1. And the grooves located on the lower side of the semi-circular groove 9 are arranged between the two collection grooves 10.

[0025] By rotatably connecting a rotating structure composed of the rotating rod 5 and the rotation frame 3 in the circular holes, then installing the electromagnet 8 in the rotation frame 3, and then using a telescopic structure composed of the elastic member 11 and the slant plate 12 installed in the grooves between the two collection grooves 10 to control the closing of the electromagnet 8, the rotating structure can continuously separate iron impurities and waste aluminum, thereby improving the separation efficiency of iron impurities and waste aluminum. And using the telescopic structure in the groove on one side close to the top of the inclined surface of the inclined block 1 to control the startup of the electromagnet 8, the power consumption can be reduced by reducing the energization duration of the electromagnet 8.

[0026] To reduce the rotational friction of the rotating rod 5, a bearing 6 is installed in the circular hole, and the rotating rod 5 is installed inside the bearing 6.

[0027] To facilitate the collection of iron impurities and aluminum, a collection frame 7 is inserted into the collection trough 10.

[0028] To prevent the waste aluminum from sliding off the inclined block 1 before being placed into the rotating frame 3, a sliding groove 2 is opened on the upper side of the inclined surface of the inclined block 1.

[0029] The specific operation process of this utility model is as follows: The crushed waste aluminum is evenly poured into the sliding groove 2, and then the servo motor is started to drive the rotating rod 5 to rotate. The aluminum waste gradually slides onto the rotating frame 3 through the sliding groove 2. When the rotating frame 3 rotates to the groove near the top of the inclined surface of the inclined block 1, the elastic member 11 releases the return elastic force to make the inclined plate 12 contact the contact switch 4, so that multiple electromagnets 8 in the rotating frame 3 are started to adsorb the iron impurities on the rotating frame 3. When the rotating frame 3 rotates to the collection trough 10 near the top of the inclined block 1, the aluminum impurities fall into the collection trough 10 under the action of gravity.

[0030] As the rotating rod 5 rotates, when the rotating frame 3 rotates to the bottommost part, the telescopic structure installed in the groove at the bottommost part of the arc-shaped groove contacts the contact switch 4 to cut off the power supply of the electromagnet 8. When the rotating frame 3 rotates to the collection trough 10 near the bottom of the inclined block 1, the iron impurities on the collection frame 7 fall into the collection trough 10, thus completing the separation of the iron impurities and the aluminum waste. And because multiple rotating frames 3 are installed on the annular surface of the rotating rod 5, when one rotating frame 3 is separating the rectangular iron impurities and aluminum waste, the other rotating frames 3 are still transporting the aluminum waste, so the separation efficiency of the iron impurities and the waste aluminum is improved.

[0031] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as this non-substantial improvement is made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
