Description

Technical Field

[0001] This utility model relates to the field of scrap iron recycling technology, and in particular to a sorting device suitable for scrap iron recycling. Background Technology

[0002] With the surge in scrap metal recycling during urbanization, sorting is a crucial step in resource reuse. Traditional sorting relies heavily on manual labor, resulting in low efficiency, high costs, and the health risks of metal corrosion. Existing mechanical sorting devices suffer from insufficient identification accuracy and difficulty in distinguishing different types of scrap metal, leading to low sorting purity and impacting the quality of recycling. Furthermore, some devices are complex in structure and energy-intensive, making them unsuitable for small and medium-sized recycling points. Therefore, developing efficient, accurate, and low-cost scrap metal recycling and sorting devices has become an urgent need for the industry.

[0003] Chinese Patent Publication No. CN222469722U discloses a utility model of a scrap iron recycling device for easy sorting. This utility model belongs to the field of sorting machines, and particularly relates to a scrap iron recycling device for easy sorting. It includes a base and an extended base. Universal wheels are fixedly connected to the lower surface of the base. The extended base is fixedly connected to the left side of the base. A sorting mechanism is arranged above the base, and a feeding mechanism is arranged above the extended base. The sorting mechanism includes a buffer unit and a sorting unit. The buffer unit includes a first support column, a spring, a second support column, and a connecting block. The first support column is fixedly connected to the upper surface of the base, and the bottom of the spring is fixedly connected to the upper surface of the first support column. This scrap iron recycling device for easy sorting is designed with a sorting mechanism that, through components such as a screen, a vibrating motor, a first screen, and a second screen, can effectively sort scrap iron. Under the action of the vibrating motor, the scrap iron slides and separates on the screen, and according to the size of the screen aperture, the scrap iron is divided into different size grades for easy processing and utilization.

[0004] Most scrap iron recycling equipment currently on the market suffers from two key shortcomings: First, it lacks the ability to remove rust from the surface of scrap iron. A large amount of rust directly affects the subsequent smelting and reprocessing of scrap iron, significantly increasing the technical difficulty and cost of scrap iron recycling and reuse. Second, the filtration process for scrap iron is ineffective, failing to effectively and fully separate impurities mixed in with the scrap iron. This forces operators to repeatedly perform filtration operations, which not only significantly increases labor intensity but also easily leads to scrap iron loss due to multiple processing, ultimately affecting the overall quality of recycled scrap iron and its subsequent utilization efficiency.

[0005] Therefore, we propose a sorting device suitable for scrap iron recycling to solve the above problems. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Reference Figure 1-5 A sorting device suitable for scrap iron recycling includes a base 1, which serves as the bottom support foundation of the entire device. A filter mechanism 2 is provided on one side of the top of the base 1 for filtering rust from scrap iron. A rotating mechanism 3 is provided on one side of the filter mechanism 2 for separating scrap iron from rust. A shock-absorbing mechanism 4 is provided on one side inside the filter mechanism 2 to reduce the noise generated by the device. A vibrator 6 is fixedly connected to one side of the shock-absorbing mechanism 4 to provide vibration for the multi-layer filter screen inside the filter mechanism 2 to assist in filtration. Four support legs 5 are provided between the base 1 and the rotating mechanism 3 to support the rotating mechanism 3. The filter mechanism 2 includes a housing 201, which serves as the basic installation frame for the entire filter system. A collection hopper 202 is fixedly connected to one side of the housing 201 to collect large-volume scrap iron after filtration, enabling collection of scrap iron without shutting down the machine. A movable plate 203 is installed at the bottom of the collection hopper 202 to facilitate the collection of scrap iron filtered by the third filter plate 209. The movable plate 203 extends through one side of the housing 201, and a collection plate 204 is located at the bottom of the movable plate 203 to collect rust. The collection plate 204 has an internal opening... The collection chamber 210 and the collection plate 204 are provided with movable grooves 206 on both sides. The inner surface of the outer shell 201 is fixedly connected with protrusions 205 on both sides. The protrusions 205 cooperate with the movable grooves 206 to ensure that the collection plate 204 can be pulled out flexibly. The top of the collection plate 204 is equipped with a third filter plate 209 for third-level fine filtration. The top of the conveyed third filter plate 209 is equipped with a second filter plate 208 to achieve middle-level filtration. The top of the outer shell 201 is equipped with a first filter plate 207 to perform the function of preliminary filtration.

[0021] Furthermore, the rotating mechanism 3 includes a housing 301, which serves as the basic installation and protective component of the rotating mechanism 3. The housing 301 has a rotating cavity 306 inside, providing space for the scrap iron to rotate. The outer surface of the housing 301 is rotatably connected to two retainers 302 via a rotating shaft, thereby stabilizing the housing 301. A connector 304 is provided between the two retainers 302, and the connector 304 is fixedly connected to the housing 301. The rotation of the connector 304 drives the rotation of the housing 301. Several protrusions 305 are fixedly connected to the inner surface of the rotating cavity 306 for removing rust from the surface of the scrap iron.

[0022] Furthermore, the bottom of the two fixtures 302 is fixedly connected to the support plate 303, which supports the housing 301. The bottom of the support plate 303 is fixedly connected to the top of the support leg 5, and the bottom of all the support legs 5 is fixedly connected to the top of the base 1, which supports the rotating mechanism 3.

[0023] Furthermore, the bumps 305 are arranged in groups of eight and in a circular array. The bumps 305 are staggered between two adjacent groups to clean the rust on the surface of the scrap iron inside the rotating cavity 306. The angle between the housing 301 and the horizontal plane is 10°-20°, which is conducive to the scrap iron slowly moving towards the filter mechanism 2 during rotation.

[0024] Furthermore, the support plate 303 has a slot 309 inside, which allows the belt 307 to pass through. The bottom of the support plate 303 is connected to the drive motor 308 by bolts, which stabilizes the drive motor 308. The drive motor 308 and the connector 304 are connected by a belt 307. By starting the drive motor 308, the housing 301 is rotated by the belt 307, which passes through the slot 309.

[0025] Furthermore, the shock absorption mechanism 4 includes a vibrating plate 401. A first filter plate 207, a second filter plate 208, and a third filter plate 209 are installed on one side of the vibrating plate 401. The vibrating plate 401 causes the multi-layer filter screen to vibrate. A shock absorption cavity 405 is provided between the vibrating plate 401 and the outer shell 201 to provide shock absorption space. A number of grooves 404 are connected to one side of the shock absorption cavity 405. The grooves 404 penetrate one side of the outer shell 201. A spring 403 is fixedly connected to one end of the inner surface of all the grooves 404. The spring 403 absorbs and buffers the vibration. A boss 402 is installed at one end of all the grooves 404. One end of the boss 402 is fixedly connected to the spring 403, and the other end is fixedly connected to one side of the vibrating plate 401. One side of the vibrating plate 401 is fixedly connected to the vibrator 6. When the vibrator 6 is activated, the multi-layer filter screen is vibrated through the vibrating plate 401 to improve the filtration effect.

[0026] Specifically, the first filter plate 207, the second filter plate 208, and the third filter plate 209 are parallel to each other, and the angle between the first filter plate 207 and the horizontal plane is 20°-30°, which improves the filtration effect.

[0027] In summary: The operator starts the drive motor 308 and vibrator 6. The belt 307, wound around the connector 304, causes the casing 301 to rotate. The operator then pours the collected scrap iron into the casing 301, where it repeatedly rubs and collides with the protrusions 305 during rotation, separating impurities and rust from the scrap iron. Because the casing 301 is at a certain angle to the horizontal surface, the cleaned scrap iron and rust fall into the filter mechanism 2. Since the holes in the first filter plate 207, second filter plate 208, and third filter plate 209 are of different sizes, the vibration of the vibrator 6 achieves a layered filtration effect. The first filter plate 207 filters out the scrap iron, and the second filter plate 208 filters out the waste material. Smaller scrap iron pieces are filtered by the third filter plate 209 to remove remaining impurities. Finally, all the rust falls into the collection plate 204. Because a shock-absorbing mechanism 4 is provided between the filter mechanism 2 and the vibrator 6, the vibration amplitude between the vibrator 6 and the vibrating plate 401 is effectively reduced by the spring 403, thereby reducing the noise generated by the vibration. During the operation of the device, the operator can collect larger scrap iron pieces through the collection hopper 202. After the device has been working for a period of time, the operator turns off the drive motor 308 and the vibrator 6, then disassembles the first filter plate 207 and the second filter plate 208 to collect smaller scrap iron pieces. The impurities are then cleaned by opening the movable plate 203. Finally, the rust inside is collected by pulling out the collection plate 204 with the handle.
