[0001] This utility model relates to the field of waste recycling equipment technology, and in particular to a metal waste sorting and recycling device. Background Technology

[0002] In the metal processing industry, the stamping process of parts such as sprockets generates a large amount of metal scrap. This scrap varies in size and shape, and directly discarding it not only wastes resources but also increases the environmental burden. Therefore, in order to improve resource utilization, it is generally sorted and recycled according to its shape and size, and then reprocessed into other parts.

[0003] Currently, existing technologies mostly separate metal waste through manual sorting or simple sieves, which is inefficient, has poor sorting accuracy, and cannot achieve automated continuous operation; it is difficult to meet the needs of industrial production for efficient and accurate sorting and recycling of metal waste.

[0004] Therefore, there is an urgent need for a highly automated metal waste sorting and recycling equipment with good sorting effect. Utility Model Content

[0028] The following is in conjunction with the appendix Figure 1-6 The embodiments of the metal waste sorting and recycling device of this utility model will be described in further detail.

[0029] A metal scrap sorting and recycling device, such as Figures 1 to 3As shown, the device includes a conveyor line 1 for conveying metal scrap to a set height, a vibrating screening mechanism 2 connected to the end of the conveyor line 1 for sorting metal scrap of different sizes, and a scrap collection box 3 located below the vibrating screening mechanism 2 for collecting metal scrap. The vibrating screening mechanism 2 includes a mounting bracket 21, a screening plate 22, and a vibrator 23. One end of the mounting bracket 21 is fixedly connected to the screening plate 22, and the other end is connected to the screening plate 22 by an elastic support member 4. The screening plate 22 is set at an angle, and baffle plates 5 are set on both sides of the screening plate 22. A fixing plate 6 is fixedly connected to the bottom end of the vibrator 23. The fixing plate 6 spans across the baffle plates 5 and is fixed to them. The vibrator 23 vibrates the screening plate 22 to cause the metal scrap to be discharged.

[0030] Specifically, the mounting bracket 21 is welded from structural steel, possessing sufficient structural strength and stability. The screening plate 22 is bolted to the mounting bracket 21, its inclination angle consistent with the ramp section 12, ensuring a natural transition of material to the surface of the screening plate 22. The screening plate 22 is made of high-strength manganese steel plate, with a hardened surface treatment, exhibiting strong wear resistance and a long service life. Multiple sets of screen holes 221 are formed on the screening plate 22, extending axially along its length, with adjacent sets of screen holes 221 arranged in a staggered manner. This arrangement increases the screening path, improves screening efficiency, and prevents material blockage between the screen holes 221. The shape of the screen holes 221 is adapted to the shape of the metal waste, and the diameter of the screen holes 221 is designed according to grading requirements; for example, the diameter of the first-stage screen hole 221 is 100mm, the second stage is 150mm, the third stage is 200mm, and so on, thus achieving multi-stage sorting. Baffle plates 5 are located on both sides of the screening plate 22 and are fixed to the edge of the screening plate 22 by bolts. The height of the baffle plates 5 can be adjusted according to the accumulation height of the metal waste to prevent the metal waste from spilling sideways. The discharge end of the screening plate 22 is designed with a tapering structure, and the baffle plates 5 correspondingly narrow inward to form a funnel-shaped outlet, so that the metal waste falls in a concentrated manner, which is convenient for subsequent collection or transfer.

[0031] The vibrator 23 is either an eccentric motor or an electromagnetic vibrator, and its bottom end is fixed to the fixed plate 6 spanning between the baffle plates 5 by bolts. The vibration frequency of the vibrator 23 is adjustable, typically ranging from 20-50Hz. By adjusting the frequency, the screening intensity and the flow speed of the metal waste can be controlled. When the vibrator 23 is working, it drives the screening plate 22 to generate high-frequency micro-amplitude vibration, causing the metal waste to jump forward on the screen surface. This allows metal waste smaller than the screen holes 221 to fall through the screen holes 221, while metal waste larger than the screen holes 221 continues to move downwards until it reaches the discharge port, thus achieving sorting.

[0032] It is worth mentioning that, such as Figure 1As shown, in this embodiment, the conveyor line 1 and vibrating screening mechanism 2 are provided in multiple sets. The diameter of the screen holes 221 in each set of vibrating screening mechanism 2 increases sequentially along the material flow direction, forming a multi-stage sorting structure. For example, after the larger-sized waste material is screened out by the first-stage vibrating screening mechanism 2, it falls into the second-stage conveyor line 1 through the discharge port of the screening plate 22 and continues to be conveyed into the second-stage vibrating screening mechanism 2 for further sorting. The sorted metal waste then enters the third-stage vibrating screening mechanism 2 for further sorting, and so on, until all metal waste of different sizes can be sorted into the corresponding waste collection box 3. This multi-stage sorting method can achieve fine sorting and meet the recycling needs of metal waste of different particle sizes.

[0033] In this embodiment, as Figure 2 As shown, the elastic support 4 uses a helical spring or a rubber spring and is symmetrically arranged between the bottom of the screening plate 22 and the mounting bracket 21.

[0034] Specifically, the function of the elastic support 4 is to buffer the impact force generated by vibration, maintain the stable operation of the system, and extend the service life of the equipment; the number and specifications of the elastic support 4 can be selected according to the size of the screening plate 22 and the power of the vibrator 23, and usually no less than 2 sets.

[0035] like Figure 5 As shown, to prevent metal scrap from splashing out of the waste collection box 3 when it falls from the screen holes 221 at the edge of the screening plate 22, in this embodiment, a discharge baffle 7 is provided on both sides of the screen holes 221 at the bottom of the screening plate 22, and is set obliquely towards the waste collection box 3. The function of the discharge baffle 7 is to guide the metal scrap passing through the screen holes 221 into the waste collection box 3, preventing the material from scattering outside. The angle of the discharge baffle 7 can be manually adjusted, usually set to 45°-60°, to ensure that the material slides smoothly into the waste collection box 3.

[0036] In this embodiment, as Figure 4 As shown, conveyor line 1 has a multi-section structure, including a level section 11 and an inclined section 12. A feed hopper 13 is located at one end of the level section 11 to receive unsorted metal scrap. The feed hopper 13 is designed in a funnel shape, with its bottom opening matching the width of the belt in the level section 11, ensuring that the material is evenly distributed on the belt surface. Additionally, anti-slip textures or baffles can be added to the surface of the belt in conveyor line 1 to further improve the conveying stability during inclined sections.

[0037] Specifically, the ramp section 12 connects to the end of the gentle section 11, and its bottom is fixed to the ground by a support frame 14. The inclination angle is designed to be 30°-60°, and in this embodiment, it is preferably 45°. This angle can effectively lift the material while preventing it from slipping during the conveying process. Discharge protection plates 15 are installed on both sides of the discharge end of the ramp section 12. The height of the protection plates is 10-15cm, and they are made of wear-resistant steel plates. Their function is to prevent material from splashing out of the equipment range during discharge, ensuring that the material accurately falls into the vibrating screening mechanism 2. The conveyor line 1 is driven by a variable frequency motor. The conveying speed can be controlled by adjusting the motor speed to adapt to the sorting requirements of different material quantities.

[0038] It should be noted that conveyor line 1 uses a belt conveyor or a chain conveyor, and its length can be adjusted according to the actual site requirements. Belt conveyors or chain conveyors are common knowledge in the prior art, and their specific structures and transmission principles are well known to those skilled in the art. Therefore, they will not be described in detail in this embodiment.

[0039] It is worth mentioning that the tilting direction of the screening plate 22 is opposite to the direction of the climbing section 12 of the conveyor line 1, and the tilting angle of the screening plate 22 is 15°-45°, preferably 30° in this embodiment. At its tilting angle, the metal waste transported from the conveyor line 1 to the vibrating screening mechanism 2 can slide down along the screening plate 22 under its own weight. At the same time, under the vibration of the vibrator 23, the problem of metal waste accumulation is effectively prevented, thereby improving the sorting efficiency.

[0040] In this embodiment, as Figure 6 As shown, the waste collection box 3 is positioned directly below the screen holes 221 to receive the metal waste falling from the screen holes 221. The metal waste falling into the waste collection box 3 can be easily moved to a designated location for cleaning and transfer using the bottom pulley assembly 31 of the waste collection box 3, according to the actual production rhythm, so as to facilitate the subsequent recycling of the sorted metal waste.

[0041] Specifically, the top opening size of the waste collection bin 3 matches the outlet of the discharge baffle 7 to ensure that all materials fall into the bin. The bin body is welded from steel plates, and the bottom is equipped with a pulley assembly 31 for easy movement and transfer. The pulley assembly 31 is equipped with a brake device to fix the position after the bin is full, preventing slippage. At the same time, an observation window and a material level sensor can be installed on the side of the waste collection bin 3 to monitor the material height inside the bin in real time and prompt the operator to replace the collection bin in time.

[0042] It should be noted that this invention is not only applicable to round metal scrap generated from sprocket processing, but can also be widely used in other metal processing industries, such as the sorting of scrap generated from bearings, gears, and fasteners. By replacing the screening plates 22 with different aperture sizes, it can adapt to the sorting needs of scrap of different shapes and sizes. In addition, this equipment can be linked with subsequent processing equipment such as crushers and smelting furnaces to form a complete waste recycling production line.

[0043] The working principle of this utility model:

[0044] Metal scrap is fed into the flat section 11 of the conveyor line 1 along the feed hopper 13. As the conveyor line 1 moves, the metal scrap enters the ramp section 12. Under the conveying action of the ramp section 12, it is lifted to a set height and finally output from the discharge end of the ramp section 12 and enters the vibrating screening mechanism 2. The scrap enters the screening plate 22 of the vibrating screening mechanism 2, and the vibrator 23 is started, which drives the screening plate 22 to vibrate through the fixed plate 6. Because the screen holes 221 on the screening plate 22 extend axially along the length direction and are staggered, during the vibration process, scrap metal of different sizes with a diameter smaller than the screen holes 221 passes through the screen holes 221 and is guided by the discharge baffle 7 to fall into the corresponding scrap collection box 3 below; scrap metal with a diameter larger than the screen holes 221 moves towards the discharge end of the screening plate 22 under the action of the vibration of the screening plate 22 and its own gravity. Because the discharge end of the screening plate 22 has a converging structure and the baffle 5 is retracted, the scrap metal is concentrated and guided to enter the next set of conveyor lines 1 and vibrating screening mechanism 2 for repeated screening. Since the diameter of the screen holes 221 of each set of vibrating screening mechanism 2 increases sequentially, it is possible to achieve accurate grading and sorting of scrap metal of different sizes.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
