Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper material screening technology, specifically a copper material screening device using magnetic suction screening. Background Technology
[0002] Copper is an important non-ferrous metal resource with high recycling value due to its small particle size, similar density, and easy mixing with other impurities.
[0003] In the metal recycling and processing process, copper screening is one of the key steps. For the sorting of copper-iron mixtures, traditional methods mainly rely on simple screening with sieve plates. The screening process is usually based on the physical size difference between copper and iron, and the mixture is graded by sieves with different aperture sizes. When the particle size of copper and iron is similar, the sieve plate cannot effectively separate them, resulting in iron impurities mixed in with the copper material, reducing the recycling purity, and making it difficult to accurately separate the copper material.
[0004] To solve the above technical problems, it is necessary to design a magnetic copper material screening device. Summary of the Invention
[0005] The purpose of this invention is to provide a magnetic copper screening device that can thoroughly screen out copper from copper-iron mixtures and has high screening efficiency. It solves the problem that traditional methods mainly rely on simple screening with screen plates, which cannot effectively separate copper and iron particles when their sizes are similar, resulting in iron impurities mixed into the copper and reducing the purity of the recovered product.
[0006] The objective of this utility model can be achieved through the following technical solution: A magnetic copper material screening device includes a housing, an adsorption mechanism installed at the top of the inner cavity of the housing, the adsorption mechanism including a fixing plate, the bottom of the fixing plate being fixedly connected to the top of the housing, a motor being connected to the rear side of the fixing plate by screws, a gear being fixedly connected to the rotating shaft of the motor, a connecting rod being fixedly connected to the front side of the gear, an electromagnetic adsorption roller being fixedly connected to the front end of the connecting rod, a support frame being provided at the bottom of the electromagnetic adsorption roller, a screening plate being provided in the inner cavity of the support frame, a toothed plate meshing at the bottom of the gear, and the front side of the toothed plate being fixedly connected to the support frame.
[0007] By setting up a fixed plate, motor, gears, connecting rods, electromagnetic adsorption rollers, support frame, screening plate, and toothed plate, the screening plate can move laterally back and forth to vibrate and screen the copper-iron mixture, pre-screening out the larger volume of the mixture. When the electromagnetic adsorption roller is energized, it generates a strong magnetic field, which can selectively adsorb iron material. Iron is a strongly magnetic material, and the adsorption effect is significant, while copper material is unaffected due to its paramagnetic properties, thus achieving preliminary separation of copper and iron and improving the screening effect.
[0008] In the aforementioned magnetic copper material screening device, support pipes are fixedly connected to both the front and rear sides of the bottom of the support frame. A crossbar is connected through the center of the surface of each support pipe, and both ends of the crossbar are fixedly connected to the inner wall of the housing. By setting the support pipes and crossbars, the support frame is guided and supported, facilitating the lateral movement of the support frame and the screening plate.
[0009] In the aforementioned magnetic copper material screening device, a vertical plate is fixedly connected to the front side of the screening plate, and spring telescopic rods are fixedly connected to both sides of the support frame. A limit block is movably connected to the front side of each spring telescopic rod, and the rear side of the limit block contacts the vertical plate. By setting the spring telescopic rods to apply pressure to the limit block, the limit block is brought into close contact with the vertical plate, thereby providing tension support for the vertical plate and the screening plate. This prevents the screening plate from separating from the support frame during lateral movement, ensuring the stability of the screening process.
[0010] In the aforementioned magnetic copper material screening device, U-shaped blocks are fixedly connected to both sides of the front of the vertical plate, and one side of the limiting block extends into the inner cavity of the U-shaped block. By setting the U-shaped blocks, the limiting blocks are positioned, making the screening plate more stable during lateral movement, preventing it from shaking or shifting, and improving screening accuracy.
[0011] In the aforementioned magnetic copper screening device, the inner cavity of the housing is connected to a first electromagnetic adsorption plate and a second electromagnetic adsorption plate via a rotating shaft. The first electromagnetic adsorption plate is located to the left of the second electromagnetic adsorption plate. After the material is vibrated and screened, fine iron particles remain. The first electromagnetic adsorption plate can adsorb some of the iron impurities, while the second electromagnetic adsorption plate further captures the iron particles and guides the waste material, increasing the adsorption area for iron in the copper-iron mixture. As the mixture passes through the electromagnetic adsorption plates at different positions, the iron can be more fully adsorbed, further improving the copper-iron separation effect and resulting in higher purity copper material.
[0012] In the aforementioned magnetic copper material screening device, electric push rods are fixedly connected to both sides of the inner wall of the box. A U-shaped plate is fixedly connected to the end of the electric push rod away from the inner wall of the box. A support roller is connected to the surface of the U-shaped plate via a rotating shaft. The top support roller contacts the first electromagnetic adsorption plate, and the bottom support roller contacts the second electromagnetic adsorption plate. By setting up the electric push rods, U-shaped plate, and support rollers, the electric push rods can push the U-shaped plate and support rollers to move, thereby adjusting the angle of the first and second electromagnetic adsorption plates. This allows one side of the first and second electromagnetic adsorption plates to vibrate, facilitating the flow of material on the adsorption plates, preventing material stagnation on the adsorption plates, and facilitating smooth material discharge. Simultaneously, it allows the electromagnetic adsorption plates to better contact the mixture, improving adsorption efficiency and enhancing the adaptability and screening effect of the entire screening device.
[0013] In the aforementioned magnetic copper screening device, a door is connected to the front of the housing via a rotating shaft, and a handle is fixedly attached to the surface of the door. An observation window is embedded in the front of the housing, and a receiving frame is placed at the bottom of the inner cavity. The door facilitates inspection, maintenance, and cleaning of the internal structure; the handle allows for easy opening and closing; the observation window allows real-time monitoring of the screening process inside the housing, providing timely information on the screening progress and equipment operating status; and the receiving frame collects the screened copper material for convenient and unified processing and removal.
[0014] Compared with existing technologies, the advantages of this magnetic copper screening device are as follows: it enables the screening plate to move laterally back and forth, vibrating and screening the copper-iron mixture, pre-screening out the larger volume of the mixture; the electromagnetic adsorption roller generates a strong magnetic field after being energized, which can selectively adsorb iron material. Iron is a strongly magnetic material, and the adsorption effect is significant, while copper material is unaffected due to its paramagnetic properties, thus achieving preliminary separation of copper and iron and improving the screening effect; the electromagnetic adsorption roller rolls on the screening plate, expanding the adsorption area.

[0022] In actual manufacturing, support tubes 28 are fixedly connected to the front and rear sides of the bottom of the support frame 25. A crossbar 29 is connected through the center of the surface of the support tube 28, and both ends of the crossbar 29 are fixedly connected to the inner wall of the box 1.
[0023] In actual manufacturing, a vertical plate 210 is fixedly connected to the front side of the screening plate 26, and spring telescopic rods 211 are fixedly connected to both sides of the support frame 25.

[0024] In actual manufacturing, U-shaped blocks 213 are fixedly connected to both sides of the front of the vertical plate 210, and one side of the limiting block 212 extends into the inner cavity of the U-shaped block 213.
[0025] In actual manufacturing, the inner cavity of the housing 1 is connected to the first electromagnetic adsorption plate 3 and the second electromagnetic adsorption plate 4 via a rotating shaft, with the first electromagnetic adsorption plate 3 located to the left of the second electromagnetic adsorption plate 4.
[0026] In actual manufacturing, electric push rods 5 are fixedly connected to both sides of the inner wall of the box 1. The end of the electric push rod 5 away from the inner wall of the box 1 is fixedly connected to a U-shaped plate 6.
