[0001] This application relates to the technical field of iron scrap processing equipment, and in particular to a vibrating screen for iron scrap silos. Background Technology
[0002] In the metal processing industry, it is often necessary to effectively treat and recycle the iron filings generated during the process. Iron filings processing equipment in related technologies typically includes hoppers and grates for screening the iron filings. Recycling iron filings can effectively improve product quality, and the recycled iron filings have application value in industrial production, reducing resource waste.
[0003] In related technologies, a blower is used to blow air onto a grate to blow iron filings down through the holes in the grate. However, in applications with large-capacity silos, the blower often fails to deliver the iron filings effectively, leading to blockages. Utility Model Content
[0004] In order to improve the feeding speed of iron filings and reduce the accumulation of iron filings, this application provides a vibrating screen for iron filings silos.
[0005] The technical solution for the iron scrap silo vibrating screen provided in this application is as follows:
[0006] A vibrating screen for iron scrap silos includes a main silo, a feeding silo, and a vibrating screening mechanism. The bottom of the main silo is inclined, and the discharge port of the main silo is located at the lowest end of the bottom wall of the main silo. The discharge port of the feeding silo is connected to the feeding port of the main silo. The vibrating screening mechanism is located inside the feeding silo and includes a vibrating motor, a vibrating grate, and a vibrating connecting rod. The vibrating motor is fixedly connected to the outer wall of the feeding silo. One end of the vibrating connecting rod is fixedly connected to the output end of the vibrating motor, and the other end passes through the side wall of the feeding silo and is connected to the vibrating screen to realize the transmission of vibration.
[0007] By adopting the above technical solution, the vibrating grate can generate effective vibration, thereby significantly improving the feeding efficiency of iron filings and reducing the accumulation of iron filings on the vibrating grate. In addition, this design also effectively saves the labor costs required for daily cleaning of iron filings.
[0008] Optionally, the number of feeding hoppers is at least two.
[0009] By adopting the above technical solutions, the design with at least two feeding hoppers significantly improves the scrap handling capacity, enabling continuous and uninterrupted alternating feeding operations and increasing production efficiency. At the same time, the multi-hopper design effectively reduces the load on individual feeding hoppers, lowers the failure rate, and further ensures the stable operation of the system.
[0010] Optionally, the inner wall of the feeding hopper is provided with a flange for supporting the vibrating grate.
[0011] By adopting the above technical solution, the inner wall of the feeding hopper is provided with a flange for supporting the vibrating grate, which ensures the stability and reliability of the vibrating grate during the vibration process and prevents it from falling off or shifting due to severe vibration.
[0012] Optionally, the bottom of the vibrating grate is provided with a buckle, and the vibrating connecting rod is provided with a fitting for engaging with the buckle.
[0013] By adopting the above technical solution, the connection between the vibrating grate and the vibrating connecting rod is made more stable and reliable, effectively preventing failure due to loosening during vibration. This design not only improves the stability of the system but also simplifies the installation and maintenance process, further enhancing work efficiency.
[0014] Optionally, a base is also included, which is connected to the main hopper via an elastic element.
[0015] By adopting the above technical solution, the base and the main hopper are connected by elastic components, which effectively reduces the vibration generated by the vibrating motor, reduces noise and vibration transmission during equipment operation, and improves the stability and service life of the equipment.
[0016] Optionally, the base is provided with a slide rail in the vertical direction, and the outer side wall of the main hopper is provided with a slide groove that cooperates with the slide rail.
[0017] By adopting the above technical solution, the vertical slide rail on the base cooperates with the sliding groove on the outer wall of the main hopper, enabling the main hopper to move up and down along a predetermined path when subjected to vibration, thereby ensuring the stability of the main hopper and avoiding lateral displacement and instability caused by vibration. Additionally, it allows the iron filings inside the main hopper to leave the hopper from the discharge port along the bottom slope under the influence of vibration.
[0018] Optionally, a control box is also included, which contains a controller that is signal-connected to the vibration motor and used to control the operating state of the vibration motor.
[0019] By adopting the above technical solution, the controller of the scrap bin vibrating screen can precisely control the working status of the vibrating motor, ensuring accurate settings for vibration frequency, time, and interval. This not only improves the efficiency and accuracy of scrap screening but also effectively reduces scrap accumulation, thereby reducing the need for manual cleaning and enhancing the level of production automation.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. The vibration of the vibrating grate driven by the vibrating motor can effectively promote the feeding of iron filings, reduce the accumulation of iron filings on the grate, and improve the processing efficiency of iron filings;
[0022] 2. By controlling the vibration frequency, time, and interval settings of the vibratory motor, precise control of the scrap feeding process is achieved, further improving the stability and reliability of the system;
[0023] 3. The dual-hopper design allows the system to perform vibration screening at different times, which not only improves the utilization rate of the equipment, but also significantly reduces the daily labor cost required for screening. Attached Figure Description

Detailed Implementation
[0027] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.
[0028] This application discloses a vibrating screen for iron scrap silos.
[0029] like Figure 1 and Figure 2 As shown, the system includes a main material bin 1, a feeding bin 2, and a vibrating screening mechanism. The bottom of the main material bin 1 is inclined, and the discharge port 101 of the main material bin 1 is located at the lowest end of the bottom wall of the main material bin 1 to facilitate the smooth discharge of iron filings. The discharge port of the feeding bin 2 is connected to the feeding port of the main material bin 1 to ensure that iron filings can smoothly enter the main material bin 1. The vibrating screening mechanism is located inside the feeding bin 2 to screen and vibrate the iron filings.
[0030] The vibrating screening mechanism includes a vibrating motor 3, a vibrating grate 4, and a vibrating connecting rod 5. The vibrating motor 3 serves as the power source and is fixedly connected to the outer wall of the feeding hopper 2 to ensure stable operation. One end of the vibrating connecting rod 5 is fixedly connected to the output end of the vibrating motor 3, and the other end passes through the side wall of the feeding hopper 2 and connects to the vibrating screen, forming a complete vibration transmission path.
[0031] From the perspective of vibration transmission path, after the vibrating motor 3 starts, it generates vibration and transmits it to the vibrating grate 4 through the vibrating connecting rod 5. Under the action of the vibration force, the vibrating grate 4 generates effective vibration, which can penetrate the iron filings layer and promote the feeding process of the iron filings. Under the action of vibration, the iron filings gradually loosen and fall along the screen holes of the vibrating grate 4, thereby achieving the screening and separation of iron filings, significantly improving the feeding efficiency of iron filings and reducing the accumulation of iron filings on the vibrating grate 4. Furthermore, this design effectively saves the labor costs required for daily cleaning of iron filings.
[0032] like Figure 1 and Figure 2 As shown, the number of feeding bins 2 should be no less than two. The dual or multiple configuration design of feeding bins 2 significantly improves the efficiency of scrap handling, enabling continuous and uninterrupted alternating feeding operations, thereby increasing production efficiency. Furthermore, the dual or multiple configuration strategy can effectively reduce the workload of individual bins, lower the failure rate, and thus ensure the stable operation of the system.
[0033] like Figure 1 and Figure 2 As shown, specifically, the inner wall of the feeding hopper 2 is equipped with a flange 201 structure to support the vibrating grate 4. The bottom of the vibrating grate 4 is designed with a buckle 401, while the vibrating connecting rod 5 is equipped with a fitting 501 that matches the buckle 401. The buckle 401 and the fitting 501 are snapped together. The flange 201 structure ensures the stability and reliability of the vibrating grate 4 during vibration, effectively preventing it from falling off due to vibration. The buckle 401 and the fitting 501 ensure the stability and reliability of the connection between the vibrating grate 4 and the vibrating connecting rod 5, significantly reducing the risk of failure caused by loose connections during vibration. This design not only enhances the stability of the system but also simplifies the installation and maintenance process, further improving operational efficiency.
[0034] like Figure 1 and Figure 2 As shown, the scrap metal bin vibrating screen may also include a base 6, which is connected to the main hopper 1 via an elastic element 7. In this embodiment, the elastic element 7 is a spring. The base 6 has a vertical slide rail 8, while the outer wall of the main hopper 1 has a groove 9 that matches the slide rail 8. Connecting the base 6 to the main hopper 1 via the elastic element 7 effectively mitigates the vibration generated by the vibrating motor 3, reduces noise and vibration transmission during equipment operation, and improves the stability and service life of the equipment. The vertical slide rail 8 on the base 6 cooperates with the groove 9 on the outer wall of the main hopper 1, allowing the main hopper 1 to move up and down along a predetermined path when subjected to vibration, thereby ensuring the stability of the main hopper 1 and avoiding lateral displacement and instability caused by vibration. Furthermore, this design allows the scrap metal in the main hopper 1 to leave the main hopper 1 from the discharge port 101 along the bottom slope under vibration.
[0035] To control the vibrating motor 3, the scrap hopper vibrating screen may also include a control box. The control box contains a controller connected to the vibrating motor 3 to control its operating status. The controller of the scrap hopper vibrating screen can precisely control the operating status of the vibrating motor 3, ensuring accurate settings of vibration frequency, time, and interval. This not only improves the efficiency and accuracy of scrap screening but also effectively reduces the accumulation of scrap on the grate, thereby reducing the need for manual cleaning and enhancing the level of production automation.
[0036] The implementation principle of the iron scrap silo vibrating screen according to this application embodiment is as follows: The bottom of the main silo 1 is inclined, and the discharge port 101 is located at the lowest end of the bottom wall to facilitate the discharge of iron scrap. The feeding silo 2 is connected to the main silo 1 to ensure that the iron scrap enters the main silo 1 smoothly. The vibrating screening mechanism is located in the feeding silo 2 and includes a vibrating motor 3, a vibrating grate 4, and a vibrating connecting rod 5. The vibrating motor 3 serves as the power source and transmits vibration to the vibrating grate 4 through the vibrating connecting rod 5, generating effective vibration to promote the discharge of iron scrap. Under the action of vibration, the iron scrap loosens and falls along the screen holes of the vibrating grate 4, realizing screening and separation, improving the discharge efficiency, and reducing accumulation.
[0037] The feeding hopper 2 is configured with no fewer than two units to achieve continuous and uninterrupted alternating feeding operations, thereby improving production efficiency, reducing the workload of individual hoppers, lowering the failure rate, and ensuring stable system operation. The inner wall of the feeding hopper 2 is equipped with a flange structure 201 to support the vibrating grate 4. The bottom of the vibrating grate 4 is designed with a buckle 401 to connect with the vibrating connecting rod 5's fitting 501, ensuring the vibrating grate 4 is stable and reliable during vibration, preventing detachment, reducing the risk of failure, enhancing system stability, simplifying installation and maintenance processes, and improving operational efficiency.
[0038] The scrap metal bin vibrating screen also includes a base 6, which is connected to the main hopper 1 via an elastic element 7. This mitigates vibration, reduces noise and vibration transmission, and improves equipment stability and service life. A vertical slide rail 8 on the base 6 engages with a sliding groove 9 on the outer wall of the main hopper 1, ensuring that the main hopper 1 moves up and down along a predetermined path during vibration, maintaining stability and avoiding lateral displacement and instability. This design allows the scrap metal inside the main hopper 1 to exit from the discharge port 101 along the bottom slope under vibration.
[0039] The scrap hopper vibrating screen also includes a control box and a controller. The controller is connected to the vibrating motor 3 to precisely control the working status of the vibrating motor 3, ensuring that the vibration frequency, time and interval are set accurately, improving the efficiency and accuracy of scrap screening, reducing accumulation, reducing the need for manual cleaning, and improving the level of production automation.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
