[0011] 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 specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0012] A particle grading and screening device for a ferrosilicon crushing line includes a vibrating screen support 1, on which a vibrating screen 4 is installed. The vibrating screen 4 is located at the discharge port of the discharge belt of the ferrosilicon crushing line. The vibrating screen 4 has two layers: an upper layer is a first screen 13, and a lower layer is a second screen 14. The aperture of the first screen 13 is larger than that of the second screen 14. A first chute 9 is provided at the discharge port of the first screen 13, and a first transfer and collection component is provided at the outlet end of the first chute 9. A receiving hopper 2 is installed at the bottom of the second screen 14, and a second chute 10 is installed at the discharge port of the receiving hopper 2. A second transfer and collection component is provided at the outlet end of the second chute 10. This invention integrates the grading and screening device directly into the end of the discharge belt of the ferrosilicon crushing line, realizing in-situ screening without the need for an additional independent screening workshop or site, thus saving valuable production space to the maximum extent. It can make full use of the existing dust removal system of the crushing line, and through reasonable pipeline connection and airflow design, effectively collect and treat the dust generated during the screening process, ensuring a dust removal efficiency of over 99%, thereby creating a clean and safe working environment for operators. The first transfer and collection assembly includes a first conveyor belt 6 and a first storage bin 11. A first discharge pipe 7 is installed on the inlet of the first storage bin 11. The input end of the first conveyor belt 6 is located at the outlet end of the first chute 9, and the output end of the first conveyor belt 6 is located at the inlet of the first discharge pipe 7. The second transfer and collection assembly includes a second conveyor belt 5 and a second storage bin 12. A second discharge pipe 8 is installed on the inlet of the second storage bin 12. The input end of the second conveyor belt 5 is located at the outlet end of the second chute 10, and the output end of the second conveyor belt 5 is located at the inlet of the second discharge pipe 8. The first screen 13 has a pore size of 2-5mm, and the second screen 14 has a pore size of 0-2mm. This allows for the precise grading of 0-5mm powder into 0-2mm powder and 2-5mm particles. The 2-5mm particles can be sold as silicon-based inoculants, increasing the unit price by 800 yuan / ton, significantly enhancing the added value of the powder and increasing the economic benefits for the enterprise. Both the first storage bin 11 and the second storage bin 12 are equipped with pneumatic gates at their bottoms, which facilitates the control of material release, makes operation convenient, and improves work efficiency. The vibrating screen 4 is designed to rotate on the vibrating screen support 1. During operation, the discharge belt of the ferrosilicon crushing line conveys 0-5mm mixed particles to the first screen 13 of the vibrating screen 4. Taking the aperture of the first screen 13 as 5mm and the aperture of the second screen 14 as 2mm as an example, particles with a diameter greater than 5mm will remain on the first screen 13 and eventually enter the first chute 9 from the discharge port of the first screen 13. Then, they are conveyed through the first chute 9 to the first conveyor belt 6 of the first transfer and collection assembly. The first conveyor belt 6 conveys them to the first discharge pipe 7, and then into the first storage bin 11 for collection. These particles can be further processed or utilized according to actual conditions. Particles with a diameter of 5mm or less fall through the first screen 13 to the second screen 14. The second screen 14 has a 2mm aperture. Under vibration, particles with a diameter of 2mm or less will pass through the second screen 14 and fall into the receiving hopper 2. From there, they enter the second chute 10 through the outlet of the receiving hopper 2, and are then transported by the second chute 10 to the second conveyor belt 5 of the second transfer and collection assembly. The second conveyor belt 5 then transports them to the second discharge pipe 8, and finally into the second storage bin 12 for collection. Particles with a diameter between 2-5mm remain on the second screen 14 and can be collected and processed according to actual needs. These particles can be sold as silicon-based inoculants, significantly improving economic efficiency.

[0013] When it is necessary to release the materials in the first storage bin 11 and the second storage bin 12, simply open the corresponding pneumatic gate. The operation is convenient and quick. Furthermore, this device is integrated into the end of the discharge conveyor belt of the ferrosilicon crushing line, eliminating the need for a separate screening space and saving production space. Simultaneously, it fully utilizes the existing dust removal system of the crushing line, effectively collecting and treating dust generated during screening through reasonable pipe connections and airflow design, ensuring a dust removal efficiency of over 99% and creating a good working environment for operators. The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
