Description

Technical Field

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

[0002] In modern industrial production, the recycling and reuse of scrap steel has become an important link. As the key equipment for processing scrap steel, the scrap steel crushing line plays an important role in improving the efficiency and quality of scrap steel recycling. With the rapid development of the steel industry, the demand for scrap steel is increasing. Traditional scrap steel processing methods are often inefficient and cannot meet the needs of large-scale production. The emergence of scrap steel crushing lines effectively solves this problem by crushing and sorting scrap steel to convert it into raw materials that can be directly used. However, during the operation of the scrap steel crushing line, the collection and treatment of waste materials faces many challenges. On the one hand, there are many types of waste materials generated during the crushing process, including metal debris, non-metallic impurities, dust, etc. The physical and chemical properties of these waste materials are different, which brings difficulties to collection and treatment. For example, metal debris has irregular shapes and is easy to scatter; non-metallic impurities are mixed with metal debris and are difficult to separate. On the other hand, the amount of waste materials generated is large. If they cannot be collected and treated in a timely and effective manner, they will not only take up a lot of space, but also may pollute the environment. For example, the flying of dust will affect the air quality, and the discharge of wastewater may cause water pollution. In order to solve these problems, relevant technologies are constantly developing. For example, advanced dust collection equipment is used to collect dust, and magnetic separation technology is used to separate metal and non-metallic impurities. However, the current technology still has some shortcomings, such as high equipment cost, unsatisfactory treatment effect, and complex operation and maintenance. Therefore, further research and improvement of waste collection and treatment technology of scrap steel crushing line has important practical significance, which is helpful to improve the economic and environmental benefits of scrap steel recycling; There are still the following defects in specific use: 1. The accumulation and agglomeration of materials can easily lead to internal blockage of 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 parts, accelerating the wear and damage of the equipment and shortening the service life of the equipment.

[0003] 2. In addition, if the magnetic particles are not effectively selected, it means that recyclable resources are wasted. Furthermore, 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, it may affect the quality of the final product, especially in industries with high purity requirements.

[0022] The complete working principle and steps of the above embodiment are as follows: 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 through the distribution device in the feed hopper 13. Secondly, the magnetic field inside the magnetic separator 1 is generated by the magnetic drum 11 to attract the magnetic substances in the material, and 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. When using: Displacement pusher mechanism for evenly distributing materials in magnetic separation area 2 steps: like Figure 3 to Figure 4 As 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 in the arc groove opened inside the snap plate 26, it realizes reciprocating longitudinal movement, so the longitudinal movement of the card shaft 28 will push the snap plate 26 to reciprocate horizontally The lateral reciprocating movement of the snap plate 26 will synchronously drive the slide plate 22 fixedly connected to the outer wall of one side of the snap plate 26 to move horizontally in the slide rail groove opened inside the top of the support frame 21, so that the lateral horizontal movement of the slide plate 22 will cause the moving plate 25 slidably connected to the wave-shaped groove opened on the surface of the slide plate 22 to move longitudinally reciprocatingly on the outer wall of the symmetrical plate 24, so that the lateral horizontal displacement of the slide plate 22 will synchronously drive the lateral rake plates 23 fixedly connected to the outer walls of both sides of the slide plate 22 to realize the random distribution of the materials falling from the feed hopper 13 in the lateral horizontal direction; Dead corner cleaning mechanism 3 steps to effectively capture and separate magnetic materials in corners that are not easily adsorbed by magnetic separator 1: like Figures 5 and 6 As shown, when the reduction motor drives the driving shaft 210 to rotate, the ring gear 31 fixedly connected to the outer wall of one side of the driving 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 rotatably 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 reciprocate longitudinally, so that the wedge block 37 fixedly connected to the outer wall of one end of the transfer rod 35 will also synchronously reciprocate longitudinally, so that the longitudinal reciprocating movement of the wedge block 37 will also pull the external rod 38 to reciprocate 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 to clean the magnetic materials in the corners that are not easily adsorbed by the magnetic separator 1 in the longitudinal direction through the longitudinal reciprocating movement of the transfer rod 35 and the external rod 38; The magnetic separation surface increasing mechanism 4 steps of increasing the surface area of ​​the magnetic drum 11 by friction and capturing the magnetic material more comprehensively: like Figures 7 and 8 As shown, when the ring gear 31 rotates, the upper convex shaft 41 sleeved on the outer wall of the ring gear 31 close to the driving shaft 210 will rotate synchronously, and then the lower convex shaft 42 eccentrically fixedly connected to the outer wall of one side of the upper convex shaft 41 will rotate synchronously, so that the bidirectional screw rod 43 rotatably connected to the axis of one side of the lower convex shaft 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 rotatably 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 will slide 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 will deflect upward, and the deflection of the lower transfer buckle 49 will synchronously drive the lower connection rod 410 to move upward, and then the lower friction cylinder 411 connected to the outer wall of one end of the lower connection rod 410 will deflect 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; like Fig. 9 As 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 upward, thereby realizing cross-blocking of the outer wall of the magnetic drum 11 through the opposite movement of the upper curtain 666 and the lower curtain 888.
