Description

Technical Field

[0001] This utility model relates to the field of submerged arc furnace technology, and in particular to a furnace body structure for an industrial silicon dual-rotation submerged arc furnace. Background Technology

[0002] The industrial silicon dual-rotary submerged arc furnace is an electric furnace used for producing industrial silicon. It employs a dual-rotation structure with both the furnace body and electrodes rotating. The furnace body rotation ensures more uniform heating of the material inside the furnace, while the electrode rotation helps improve the contact between the electrodes and the furnace charge. The furnace body structure has the following features:

[0003] 1. Furnace shell of electric arc furnace: serving as the main supporting structure of the furnace body;

[0004] 2. Feed port: Used to add raw materials such as ore, reducing agent, and solvent into the furnace to ensure the continuous operation of the smelting process;

[0005] 3. Exhaust duct: This duct discharges the fumes containing gases such as carbon monoxide and dust generated during the smelting process. It is usually connected to subsequent purification equipment to reduce environmental pollution.

[0006] 4. Electrodes: These are key components for introducing current into the furnace. They are located at the upper end of the furnace shell of the submerged arc furnace, and there are usually three of them. The electrodes generate an electric arc by interacting with the material inside the furnace, releasing heat for smelting.

[0007] The feeding method usually involves directly feeding raw materials into the furnace through the feeding port. During the feeding process, in order to facilitate feeding, the furnace material is placed next to the feeding port and scattered around the feeding port. However, as the furnace material decreases, the furnace material at the bottom becomes more and more scattered. The staff needs to spend more time to gather the scattered furnace material to complete the feeding, which reduces the feeding efficiency. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a furnace body structure for an industrial silicon dual-rotary submerged arc furnace. This solves the technical problem that during the charging process, in order to facilitate charging, the furnace charge is placed next to the charging port, and the furnace charge is scattered around the charging port. However, as the furnace charge decreases, the furnace charge at the bottom becomes more and more scattered, and the staff needs to spend more time to gather the scattered furnace charge to complete the charging, thereby reducing the charging efficiency.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An industrial silicon dual-rotary submerged arc furnace structure includes a furnace shell with a charging port on the outside. A stacking mechanism for accumulating furnace charge is provided on one side of the furnace shell corresponding to the charging port. The stacking mechanism includes a stacking frame, a pusher plate, a through hole, and a pusher rod. The stacking frame is located outside the furnace shell and is used to store furnace charge. The pusher plate is slidably connected to the inside of the stacking frame and is used to push the furnace charge. The through hole is located on the outside of the stacking frame and communicates with the inside of the stacking frame. The pusher rod is slidably connected inside the through hole, and the end of the pusher rod is fixedly installed on the outside of the pusher plate.

[0011] Preferably, a limiting screw is provided on the upper surface of the stacking frame, a fixing rod is connected to the external thread of the limiting screw, and a push rod is slidably connected to the outside of the limiting screw.

[0012] Preferably, the upper surface of the stacking frame is provided with an installation groove, the end of the limiting screw is engaged inside the installation groove, the installation groove is provided with an internal groove, and a spring piece is fixedly connected inside the internal groove.

[0013] Preferred configuration: Mounting blocks are fixedly installed at both ends of the stacking frame corresponding to the furnace shell of the electric arc furnace. Each mounting block has a round hole on its outside, and a fixing screw is rotatably connected inside each round hole. Nuts are provided at both ends of the stacking frame, and the fixing screws are threaded into the inside of the nuts. Slots are provided at both ends of the stacking frame, and the nuts are engaged inside the slots.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The furnace charge is poured into the stacking frame, which can serve as a temporary storage point to prevent the furnace charge from scattering. At this time, push the push rod, and the push plate will push the furnace charge from the inside of the stacking frame into the electric arc furnace under the push rod. The appropriate amount of furnace charge can be pushed into the electric arc furnace as needed. At the same time, the combined use of the push rod and the push plate can quickly push the furnace charge into the electric arc furnace, reducing the time for manual handling of the furnace charge and improving the charging efficiency.

[0016] 2. After the furnace charge in the stacking frame is fully pushed in, the push rod is slidably connected to the outside of the limit screw. Then, the fixing rod is connected to the limit screw to fix the position of the push rod. At this time, the push plate will close the feeding port to prevent heat loss and external impurities from entering. Attached Figure Description

[0024] This application provides an industrial silicon dual-rotary submerged arc furnace structure, which effectively solves the technical problem that during the charging process, in order to facilitate charging, the furnace charge is placed next to the charging port 2 and scattered around the charging port 2. However, as the furnace charge decreases, the furnace charge at the bottom becomes more and more scattered, and the staff needs to spend more time to gather the scattered furnace charge to complete the charging, thereby reducing the charging efficiency.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this embodiment effectively solves the problem that during the charging process, in order to facilitate charging, the furnace charge is placed next to the charging port 2, and the furnace charge is scattered around the charging port 2. However, as the furnace charge decreases, the furnace charge at the bottom becomes more and more scattered, and the staff needs to spend more time to gather the scattered furnace charge to complete the charging, thereby reducing the charging efficiency. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a furnace body structure for an industrial silicon dual-rotation submerged arc furnace, including a furnace shell 1. A feeding port 2 is provided on the outside of the furnace shell 1. A stacking mechanism for stacking furnace charge is provided on one side of the furnace shell 1 corresponding to the feeding port 2. The stacking mechanism includes a stacking frame 3, a pusher plate 4, a through hole 5, and a pusher rod 6. The stacking frame 3 is located outside the furnace shell 1 and is used to store furnace charge. The pusher plate 4 is slidably connected to the inside of the stacking frame 3 and is used to push the furnace charge. The through hole 5 is located on the outside of the stacking frame 3 and communicates with the inside of the stacking frame 3. The pusher rod 6 is slidably connected inside the through hole 5, and the end of the pusher rod 6 is fixedly installed on the outside of the pusher plate 4.

[0028] The upper surface of the material frame is provided with a limiting screw 7, and a fixing rod 8 is connected to the external thread of the limiting screw 7. The push rod 6 is slidably connected to the outside of the limiting screw 7. The upper surface of the stacking frame 3 is provided with an installation groove 9, and the end of the limiting screw 7 is engaged in the interior of the installation groove 9. The end of the limiting screw 7 is a T-shaped block.

[0029] The mounting slot 9 has an internal slot 10, and a spring piece 11 is fixedly connected inside the internal slot 10. One end of the spring piece 11 is fixed inside the internal slot 10, and the other end extends outward.

[0030] Mounting blocks 12 are fixedly installed at both ends of the furnace shell 1 corresponding to the stacking frame 3. Each mounting block 12 has a round hole 13 on its outside. A fixing screw 14 is rotatably connected inside each round hole 13. Both ends of the stacking frame 3 have slots 16. A nut 15 is engaged inside each slot 16. The detachable connection between the nut 15 and the slot 16 facilitates the replacement of the nut 15. The fixing screw 14 is threadedly connected inside the nut 15.

[0031] Stacking box 3: Temporarily stores raw materials to be added to the furnace, preventing them from scattering and improving feeding efficiency;

[0032] Push plate 4 and push rod 6: Push plate 4 pushes the furnace charge from the inside of the stacking frame 3 into the electric arc furnace under the push of push rod 6. The staff pushes the corresponding amount of furnace charge into the electric arc furnace according to the needs.

[0033] Limiting screw 7 and fixing rod 8: can fix the position of push rod 6, so that push plate 4 can close the feeding port 2;

[0034] Mounting slot 9: The detachable connection between the limiting screw 7 and the mounting slot 9 facilitates the replacement of the limiting screw 7;

[0035] Built-in groove 10 and spring piece 11: When the end of the limiting screw 7 is inserted into the interior of the mounting groove 9, the end of the limiting screw 7 compresses the spring piece 11. When the end of the limiting screw 7 is inserted into the interior of the mounting groove 9, the spring piece 11 fits against the end of the limiting screw 7, increasing the connection stability between the limiting screw 7 and the mounting groove 9.

[0036] Fixing screw 14 and nut 15: The detachable design of fixing screw 14 and nut 15 facilitates the installation and disassembly of the stacking frame 3, improving maintenance efficiency.

[0037] Working principle:

[0038] The first step is to pour the furnace charge into the stacking frame 3 to prevent the furnace charge from scattering. At this time, push the push rod 6. Under the push of the push rod 6, the push plate 4 pushes the furnace charge from the inside of the stacking frame 3 into the electric arc furnace. The appropriate amount of furnace charge can be pushed into the electric arc furnace as needed.

[0039] In the second step, after the furnace charge in the stacking frame 3 is fully pushed in, the push rod 6 is slidably connected to the outside of the limiting screw 7. Then, the fixing rod 8 is connected to the limiting screw 7 to fix the position of the push rod 6. At this time, the push plate 4 closes the feeding port 2 to prevent heat loss and external impurities from entering. If the stacking frame 3 is not needed, the fixing screw 14 is rotated to release the connection between the fixing screw 14 and the nut 15.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
