Description

Technical Field

[0002] With the development of industry, my country is not only a major producer of polyester raw materials, but also a major user of polyester products. The application of polyester products has spread to all areas of daily life, and the amount of waste polyester products is also amazing. The recycling of plastic products is currently the best way to solve the problem of plastic waste. During the recycling and regeneration process of plastic products, metal impurities will generally adhere to the crushed waste plastics. Therefore, the metal impurities in the plastic fragments need to be removed before regeneration.

[0003] A Chinese patent document (application publication number CN219111885U) discloses a magnetic metal impurity removal device, which includes a filter body, a first motor is provided on the top of the filter body, and a feeding port is provided at one end of the first motor, a material guide plate is provided at the lower end of the feeding port, the bottom of the first motor is connected to a rotating shaft, and a stirring blade is provided on the rotating shaft, electromagnetic blocks are provided on both sides of the stirring blade, and a first electromagnetic plate and a second electromagnetic plate are provided at the lower end of the electromagnetic block.

[0004] It can be seen that the patent document cited above allows the material to enter the filter body so that impurities can be better removed. By setting the electromagnetic wheel and the first discharge port, the problem of the falling material not getting better secondary adsorption and falling into the discharge port is solved. However, after the metal impurities in the material are removed, since the filter body is not equipped with a cleaning component, some of the metal impurities will adhere to the surface of the electromagnetic plate, which will affect the magnetic attraction of the electromagnetic plate to the metal impurities in the subsequent material, thereby affecting the removal effect of the metal impurities.

The combing rod 807 and the scraper 806 are connected. Sliding connection, when the electric telescopic rod 804 is in normal state, the scraper 806 is in contact with the top of the electromagnetic plate 6, and the second motor 801 works to drive the scraper 806 to move, so that it can scrape off the metal impurities on the surface of the electromagnetic plate 6. When the electric telescopic rod 804 is in the maximum stroke, the bottom end of the combing rod 807 is slightly higher than the fixed frame 7. When the electric telescopic rod 804 is in half the stroke, the bottom end of the combing rod 807 just contacts with the top of the electromagnetic plate 6. At this time, the second motor 801 can work to drive the scraper 806 and the combing rod 807 to move, so that the material that falls on the electromagnetic plate 6 is combed and spread out, thereby improving the impurity removal effect.

[0031] The present embodiment provides a plurality of combing rods 807, each of which is provided with a spring 808 on its outer wall, and a limit block 809 is installed at the top end of the combing rod 807, the bottom end of the limit block 809 is fixedly connected to the top end of the spring 808, and when the electric telescopic rod 804 is at half of its stroke, the spring 808 is in a normal state.

[0032] The present embodiment provides a de-impurity box 1 with a feed port 101 at the top, a discharge port 102 at one side, an obliquely arranged electromagnetic roller member 2 at the bottom end of the inner wall of the de-impurity box 1 near the discharge port 102, and the electromagnetic roller member 2 adopts the connecting part of the electromagnetic roller and the motor in the cited document, which is an existing component.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0036] How it works

[0037] Open the electromagnetic plate 6 and the electromagnetic roller 2, and put the material containing metal impurities into the feeding port 101 at the top of the impurity removal box 1, so that it falls onto the electromagnetic plate 6, and then turn on the electric telescopic rod switch, the electric telescopic rod 804 works to drive the scraper 806 to move upward through the connecting block 805 until the electric telescopic rod 804 extends half of its stroke. At this time, the combing rod 807 contacts the electromagnetic plate 6, and then turn on the second motor switch, the second motor 801 works to drive the connecting seat 803 to move to the right through the screw rod, and then drives the scraper 806 to move to the right. Under the action of the scraper 806 and the combing rod 807, the material is combed and spread to the right, and then the electric telescopic rod 804 is extended to the maximum. At the stroke, the electromagnetic plate 6 can fully absorb the metal impurities in the material, thereby improving the removal effect of the metal impurities. Then, the first motor switch is turned on, and the first motor 3 works to drive one end of the electromagnetic plate 6 to rotate downward through the rotating shaft 4, so that the material on the electromagnetic plate 6 falls downward, and is discharged from the discharge port 102 after being removed by the electromagnetic roller 2 again. Secondly, after resetting the scraper 806, the electromagnetic plate 6 and the electromagnetic roller 2 are closed, and the second motor 3 is turned on again. The second motor 3 drives the scraper 806 to move to the right, so that it can scrape the metal impurities attached to the electromagnetic plate 6 downward, thereby avoiding affecting the magnetic attraction of the electromagnetic plate to the metal impurities in the subsequent materials, thereby not affecting the removal effect of the metal impurities.
