[0035] When in use, materials are put into the screening box 8 through the feed hopper 10, and the large particles are screened by the screen 9. The materials that meet the particle size requirements pass through the screen 9. After passing through the screen 9, the materials are transported to the inside of the metering box 14 through the discharge pipe 12, and the weight sensor 15 measures the materials. While the materials are being screened, the first motor 19 drives the first rotating rod 20 to rotate, so that the angle between the first baffle 21 and the conveying pipe 5 changes, which is convenient for the materials to pass through the discharge channel into the inside of the metering box 14. By controlling the rotation angle of the first baffle 21, it is convenient to adjust the material discharge speed. As the material inside the metering box 14 continues to increase, the reading of the weight sensor 15 also changes continuously.

When feeding into the screening box 8, the screening box 8 is forced to squeeze the spring 26. Under the action of the material and the rebound force of the spring 26, the screening box 8 keeps shaking, thereby improving the screening efficiency of the screen 9.

[0040] In this embodiment, a vibration motor 27 is disposed outside the screening box 8 . When the vibration motor 27 is working, the vibration of the screening box 8 is accelerated, thereby further improving the screening efficiency of the screen 9 .

The second rotating rod 30 penetrates the discharge pipe 11 and extends to the inside of the discharge pipe 11. The second rotating rod 30 is fixedly connected to the second baffle 31. When in use, the second motor 29 is started, and the second rotating rod 30 drives the second baffle 31 to rotate synchronously, so that the second baffle 31 rotates synchronously.

As the discharge continues, the reading of the weight sensor 15 changes continuously. When the reading of the weight sensor 15 reaches 90% of the set value, the discharge speed is gradually slowed down, thereby facilitating further improving the feeding accuracy of the auxiliary material.

The cylinder 33 drives the connected cleaning block 34, and the cleaning block 34 is slidably arranged inside the feeding pipe 6. The cylinder 33 drives the cleaning block 34 to slide inside the feeding pipe 6, so as to facilitate the material inside the feeding pipe 6 to be pushed into the inside of the metallurgical furnace body 18, and at the same time, the inside of the feeding pipe 6 can be cleaned.

[0043] The working principle of an auxiliary material adding device for a metallurgical furnace in the embodiment of the present application is as follows:

[0044] Materials are put into the screening box 8 through the feed hopper 10, and large particles are screened by the screen 9. Materials that meet the particle size requirements pass through the screen 9. After passing through the screen 9, the materials are transported to the inside of the metering box 14 through the discharge pipe 12. The weight sensor 15 measures the materials. While the materials are being screened, the first motor 19 drives the first rotating rod 20 to rotate, so that the angle between the first baffle 21 and the conveying pipe 5 changes, which is convenient for the materials to pass through the discharge channel and enter the inside of the metering box 14. By controlling the rotation angle of the first baffle 21, it is convenient to adjust the material discharge speed. As the material inside the metering box 14 continues to increase, the reading of the weight sensor 15 also changes continuously. When the reading of the weight sensor 15 reaches 90% of the set value, the discharge speed is gradually slowed down, which is convenient for improving the metering accuracy of the material inside the metering box 14. After the metering is completed, the material is transported to the feeding pipe 6 through the conveying pipe 5 and sent to the inside of the metallurgical furnace body 18 through the feeding pipe 6.

[0045] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
