Description

Technical Field

[0001] The present invention relates to the technical field of steelmaking, in particular to a waste material collecting and processing device for a scrap steel crushing line. Background Art

[0002] The recycling and reuse of scrap steel has become a crucial component of modern industrial production. Scrap shredding lines, as key equipment for scrap processing, play a vital role in improving the efficiency and quality of scrap steel recycling. With the rapid development of the steel industry, demand for scrap steel is increasing. Traditional scrap processing methods are often inefficient and unable to meet the needs of large-scale production. The emergence of scrap shredding lines effectively addresses this problem by crushing and sorting scrap steel, converting it into directly usable raw materials. However, the collection and treatment of scrap material during the operation of scrap shredding lines presents numerous challenges. Firstly, the shredding process generates a wide variety of waste materials, including metal debris, non-metallic impurities, and dust. These materials have varying physical and chemical properties, making their collection and treatment difficult. For example, metal debris has irregular shapes and easily scatters, while non-metallic impurities are mixed with metal debris, making them difficult to separate. Secondly, the large amount of waste generated, if not collected and treated promptly and effectively, not only takes up a large amount of space but also poses environmental risks. For example, the flying dust affects air quality, and the discharge of wastewater can pollute water bodies. To address these issues, relevant technologies are constantly being developed. For example, advanced dust collection equipment is used to collect dust, and magnetic separation technology is used to separate metallic and non-metallic impurities. However, current technologies still have some shortcomings, such as high equipment costs, unsatisfactory treatment effects, and complex operation and maintenance. Therefore, further research and improvement of scrap crushing line waste collection and treatment technology is of great practical significance and will help improve the economic and environmental benefits of scrap recycling.

[0003] There are still the following defects in specific use:

[0004] 1. The accumulation and agglomeration of materials can easily lead to blockage inside the equipment, hindering the normal flow of materials, thereby interrupting or slowing down the production process and reducing the overall production efficiency. At the same time, uneven material distribution and agglomeration may lead to insufficient mixing, affecting the uniformity of product ingredients, resulting in uneven quality of the final product. The accumulated and agglomerated materials may produce uneven pressure and friction on the inner wall of the equipment, stirring device and other components, accelerating the wear and damage of the equipment and shortening the service life of the equipment.

[0005] 2. In addition, if the magnetic particles are not effectively selected, it means that recyclable resources are wasted. Moreover, if the magnetic particles are missed, additional cleaning or separation steps may be required, thereby increasing production costs. At the same time, if the magnetic particles are not effectively separated, the quality of the final product may be affected, especially in industries with high purity requirements.

[0054] Summary 3: Compared with the prior art, when magnetic separation is performed on mixed materials with large differences in magnetic strength, it is difficult for the magnetic separator 1 to accurately separate materials with different magnetic strengths. The friction between the rotating upper friction cylinder 46 and the magnetic roller 11 of the present invention can remove impurities and non-magnetic substances that may be adsorbed on the surface of the magnetic roller 11, keep the surface of the magnetic roller 11 clean and the magnetism effectively exerted, thereby improving the adsorption capacity and separation effect of magnetic materials, and significantly improving the magnetic separation efficiency. At the same time, the existence of the magnetic separation surface increasing mechanism 4 increases the effective contact area between the magnetic roller 11 and the material, which means that in the same time and space, more materials can be fully contacted with the magnetic roller 11. The contact between the magnetic drum and the separator is improved, and the processing capacity of the magnetic separator 1 is improved. Moreover, the friction effect helps to optimize the magnetic field distribution on the surface of the magnetic drum 11, making the magnetic field more uniform and stable, which makes the magnetic material more uniform during the adsorption process, reduces the omission and deviation of the magnetic material, and through continuous friction and cleaning, reduces the instability and vibration of the equipment caused by the uneven attachments on the surface of the magnetic drum 11, thereby ensuring that the magnetic separator 1 can operate stably for a long time and reduce the occurrence rate of failures. Finally, the surface wear and attachments are removed in time, which reduces the damage to the magnetic drum 11, extends the service life of the magnetic drum 11, and reduces the cost of equipment replacement and maintenance.

[0055] The complete working principle and steps of the above embodiment are as follows:

[0056] Initial qualification: Figure 1 As shown, first, the material is fed into the feed hopper 13 of the magnetic separator 1, usually in a continuous or intermittent manner. Then, after entering the magnetic separator 1, the material is evenly distributed on the surface of the magnetic drum 11 by the distribution device in the feed hopper 13. Secondly, the magnetic field inside the magnetic separator 1 is generated by the magnetic drum 11, which attracts the magnetic substances in the material. These magnetic substances are adsorbed to the surface of the magnetic drum 11. Finally, since the magnetic substances are adsorbed on the magnetic drum 11, non-magnetic substances such as stones and impurities will continue to flow and be discharged through the discharge hopper 12. Then, when the magnetic drum 11 is driven by the motor 15 to rotate, the adsorbed magnetic substances will be stripped off. This is usually achieved by a cleaning device such as a scraper or a cleaning brush to remove the magnetic substances from the surface of the magnetic drum 11 and collect them in the feed hopper 13.

[0057] When using:

[0058] Displacement pusher mechanism for evenly distributing materials in the magnetic separation area 2 steps:

[0059] like Figures 3 and 4As shown, in the process of the material falling through the feed hopper 13 and being adsorbed on the surface of the magnetic drum 11 by the magnetic field, the reduction motor connected to the output end of one end of the drive shaft 210 is started, and then the reduction motor drives the drive shaft 210 to rotate, so that the rotation of the drive shaft 210 drives the rotating rod 29 connected to the outer wall of one side of the drive shaft 210 to rotate, and thus the rotation of the rotating rod 29 drives the card shaft 28 fixedly connected to one end of the rotating rod 29 to move synchronously, and the card shaft 28 is slidably connected to the arc groove opened inside the snap plate 26, so that as the deflection displacement trajectory of the card shaft 28 is realized, it realizes reciprocating longitudinal movement in the arc groove opened inside the snap plate 26, so the longitudinal movement of the card shaft 28 pushes the snap plate 26 to reciprocate horizontally. The lateral movement of the slide 22 will cause the movable plate 25 slidably connected to the wave-shaped groove on the surface of the slide 22 to move longitudinally and reciprocally on the outer wall of the symmetrical plate 24. The lateral displacement of the slide 22 will synchronously drive the lateral rake plates 23 fixedly connected to the outer walls of both sides of the slide 22 to achieve random distribution of the materials falling from the feed hopper 13 in the lateral direction.

[0060] The dead corner cleaning mechanism 3 steps to effectively capture and separate magnetic materials in the corners that are not easily adsorbed by the magnetic separator 1:

[0061] like Figures 5 and 6As shown, when the reduction motor drives the drive shaft 210 to rotate, the ring gear 31 fixedly connected to the outer wall of one side of the drive shaft 210 will rotate synchronously, and then the helical gear 32 meshing with the ring gear 31 will rotate, thereby the left fixed shaft disc 33 connected to the lower end of one side of the helical gear 32 will rotate along with the rotation of the helical gear 32, and at the same time, a connecting rod 36 is connected to the outer wall of one side of the left fixed shaft disc 33, and the end of the connecting rod 36 away from the left fixed shaft disc 33 is connected to the outer wall of the right fixed shaft disc 310, so that when the left fixed shaft disc 33 rotates, it will drive the right fixed shaft disc 310 to rotate, and the helical gear 32 The left cam 34 fixedly connected to the bottom end of the side away from the left fixed shaft disc 33 will also rotate, so that the transfer rod 35 eccentrically fixedly connected to one end of the left cam 34 will undergo longitudinal reciprocating movement, so that the wedge block 37 fixedly connected to the outer wall of one end of the transfer rod 35 will also undergo longitudinal reciprocating movement synchronously, so that the longitudinal reciprocating movement of the wedge block 37 will also pull the external rod 38 to move longitudinally, and then the longitudinal reciprocating movement of the external rod 38 will push the right cam 39 to rotate, thereby pulling the wedge block 37 in the longitudinal direction to clean the magnetic materials in the corner positions that are not easily adsorbed by the magnetic separator 1 through the longitudinal reciprocating movement of the transfer rod 35 and the external rod 38;

[0062] The magnetic separation surface increasing mechanism 4 steps to increase the surface area of ​​the magnetic drum 11 by friction and capture magnetic materials more comprehensively:

[0063] like Figures 7 and 8 As shown, when the ring gear 31 rotates, the upper cam 41 sleeved on the outer wall of the ring gear 31 close to the drive shaft 210 will rotate synchronously, and then the lower cam 42 eccentrically fixedly connected to the outer wall of one side of the upper cam 41 will rotate synchronously, so that the bidirectional screw rod 43 connected to the axis of one side of the lower cam 42 will rotate, so that the rotation of the bidirectional screw rod 43 will cause the square block 47 to slide downward on the outer wall of the bidirectional screw rod 43, and then the upper transfer buckle 44 connected to the outer wall of the square block 47 will deflect downward, so that the downward deflection of the upper transfer buckle 44 will pull the upper transfer rod 45 fixedly connected to one end of the upper transfer buckle 44 When the two-way screw rod 43 is rotated, the lower transfer buckle 49 slides upward on the outer wall of the two-way screw rod 43, so the lower transfer buckle 49 connected to the outer wall of the rectangular block 48 is deflected upward. The deflection of the lower transfer buckle 49 will synchronously drive the lower transfer rod 410 to move upward, and then the lower friction cylinder 411 connected to the outer wall of one end of the lower transfer rod 410 is deflected to the left. In summary, the deflection angle of the upper friction cylinder 46 and the lower friction cylinder 411 contacts the outer wall of the magnetic cylinder 11 to achieve friction on the outer wall of the magnetic cylinder 11.

[0064] like Figure 9As shown, during the rotation of the bidirectional screw rod 43, the upper diamond block 555 on the outer wall of the bidirectional screw rod 43 will move downward, and then the upper curtain 666 fixedly connected to the upper diamond block 555 will move downward. Similarly, the lower diamond block 777 moves upward on the outer wall of the bidirectional screw rod 43, and will pull the lower curtain 888 to move upward, and then the cross-blocking of the outer wall of the magnetic drum 11 is achieved through the opposite movement of the upper curtain 666 and the lower curtain 888.
