Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial silicon production safety technology, specifically to an emergency response system for an industrial silicon electric furnace. Background Technology
[0002] Currently, most industrial silicon electric furnaces in China are 33000KVA semi-enclosed rotary furnaces. These furnaces have five tapholes evenly distributed around the furnace center, serving as the origin. The bottom of the furnace features a circular track, a drive motor, and pinions. The motor drives the gears, which in turn rotate the furnace chamber. Under normal conditions, the furnace can rotate 360°. This rotation prevents the crucible from shrinking, expands the reaction zone, and ensures efficient smelting.
[0003] In the process of industrial silicon production, when an abnormal leak of molten silicon occurs, the emergency ditch under the electric furnace can be used to collect the leaked high-temperature molten silicon. The molten silicon is discharged into the emergency ditch to prevent the high-temperature molten silicon from flowing out, thus preventing damage to workshop equipment and structures, and protecting the safety of personnel and equipment. It plays a very important role in safe production.
[0004] In actual industrial silicon production, the problem of silicon water leakage has multiple direct and indirect causes:
[0005] 1. Oxidation caused by long-term use of the furnace hole, enlarged furnace hole due to lack of operator skills, and high internal pressure caused by abnormal operation can all lead to inadequate sealing of the furnace hole, resulting in silicon water leakage.
[0006] 2. The electric furnace has exceeded its service life, causing corrosion of the refractory materials inside the furnace, which burns through the furnace body and causes silicon water leakage.
[0007] 3. Long-term use of the silicone bag that holds the silicone solution can cause the bag wall to thin, resulting in abnormalities such as bag penetration and silicone solution leakage.
[0008] The existing accident trenches are insufficient to address the silicon water leakage problems caused by the above reasons. Utility Model Content
[0009] To address the technical problem that existing accident ditches are insufficient to handle silicon molten metal leaks caused by various reasons, this utility model provides an emergency handling system for industrial silicon electric furnaces. By setting up a first ditches and a second ditches, a ring structure is formed at the bottom of the silicon electric furnace. In the event of various silicon molten metal leaks, the leaked silicon molten metal can flow into the first or second ditches, thereby protecting the safety of personnel and equipment.
[0010] The technical solution of this utility model is:
[0011] An emergency response system for an industrial silicon electric furnace, comprising:
[0012] The first chasm has a U-shaped structure and is located on the outer periphery of the bottom of the silicon furnace.
[0013] The second ditch is arc-shaped, with its two ends respectively located on the first ditch, and a through opening is provided between the second ditch and the first ditch;
[0014] The second gap and the arc-shaped section of the first gap together form a complete annular structure that surrounds the bottom of the silicon furnace.
[0015] Optionally, the furnace eye of the industrial silicon electric furnace is located above the first or second divider.
[0016] Optionally, both the first and second ditches are equipped with steel mesh and filled with concrete.
[0017] Optionally, the inner walls of the first and second dividers are lined with refractory bricks.
[0018] Optionally, the two annular tracks at the bottom of the industrial silicon electric furnace are located on both sides of the first gully.
[0019] Optionally, a silicon package driven by a winch can run on the annular track, with the second gap located on the side closer to the winch.
[0020] Optionally, the depth-to-width ratio of the first gap is 2:3, and the depth-to-width ratio of the second gap is 1:2.
[0021] Optionally, the second divider is provided with the through openings at both ends of the second divider and the first divider.
[0022] Optionally, the first gully and the second gully are at the same height, and the opening is close to the bottom of the first gully and the second gully.
[0023] Optionally, the two ends of the first gap are output ports.
[0024] Compared with the prior art, the beneficial effects of this utility model are:
[0025] By setting up a first and second trough, a ring structure is formed at the bottom of the silicon furnace. In the event of various silicon molten metal leakage problems in the silicon furnace, the leaked silicon molten metal can flow into the first or second trough, thereby protecting the safety of personnel and equipment.

[0034] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0035] Example:
[0036] See Figure 1 This embodiment discloses an emergency handling system for an industrial silicon electric furnace, including a first gap 10 and a second gap 20.
[0037] The first trough 10 has a U-shaped structure and is located on the outer periphery of the bottom of the silicon electric furnace 30. The two ends of the first trough 10 are output ports 11, which can be used to pour molten silicon.
[0038] The second ditch 20 is arc-shaped, with its two ends located on the first ditch 10 and on both sides of the first ditch 10. A through-hole 21 is provided between the second ditch 20 and the first ditch 10. The arc-shaped section of the second ditch 20 and the first ditch 10 together form a complete annular structure that surrounds the bottom of the silicon electric furnace 30.
[0039] By setting up a first ditch 10 and a second ditch 20, a ring structure is formed at the bottom of the silicon furnace 30. In the event of various silicon molten metal leakage problems in the silicon furnace 30, the leaked silicon molten metal can flow into the first ditch 10 or the second ditch 20, thereby protecting the safety of personnel and equipment.
[0040] In one specific embodiment:
[0041] The furnace hole 31 of the silicon electric furnace 30 is located above the first ditch 10 or the second ditch 20, so that when silicon water leakage occurs at the furnace hole 31, the leaked silicon water can flow into the first ditch 10 and the second ditch 20.
[0042] In another specific embodiment:
[0043] See Figure 2 and Figure 3Both the first ditch 10 and the second ditch 20 are equipped with steel mesh 40 and filled with concrete. The steel mesh 40 is laid on the inner walls and bottom of both ditch 10 and the second ditch 20, and the concrete is poured on all the steel mesh 40. By setting up the steel mesh 40 and pouring concrete, the strength of the first ditch 10 and the second ditch 20 can be enhanced, preventing collapse.
[0044] In another specific embodiment:
[0045] The inner walls of the first gully 10 and the second gully 20 are lined with refractory bricks 50. By lining with refractory bricks 50, the high temperature resistance of the first gully 10 and the second gully 20 can be improved, preventing silica water from contacting the concrete and causing an explosion.
[0046] In another specific embodiment:
[0047] The bottom of the industrial silicon electric furnace 30 is provided with two annular tracks 32 with the same direction, and the two annular tracks 32 are located on both sides of the first ditch 10 for silicon package operation.
[0048] In another specific embodiment:
[0049] The depth-to-width ratio of the first gully 10 is 2:3, and the depth-to-width ratio of the second gully 20 is 1:2.
[0050] Specifically:
[0051] At an elevation of 0 meters (750mm from the foundation wall of silicon electric furnace 30, i.e., level with the bottom of silicon electric furnace 30, the same below), a foundation trench with a depth of 1100mm and a width of 3000mm is dug down. 16mm diameter steel bars are laid and woven in the foundation trench to form a steel mesh 40. Concrete is poured at the location of an accident trench with a width of 1100mm and a depth of 700mm. After solidification, 100mm thick refractory bricks 50 are placed on the bottom and sides of the accident trench, finally forming the first ditch 10.
[0052] Using the electric furnace foundation wall as a reference, a foundation trench with a depth of 1000mm and a width of 3000mm is dug down from the 0-meter elevation. The foundation trench is also reinforced with 16mm diameter steel bars to prevent settlement. An accident trench with a width of 1200mm and a depth of 600mm is reserved before pouring concrete. After pouring, 100mm thick refractory bricks 50 are placed on the bottom and sides of the accident trench to form a second ditch 20.
[0053] The refractory brick 50 can prevent the silica water from exploding when it comes into contact with the concrete. A steel reinforcement foundation is set at the point where it overlaps with the first ditch 10 to prevent the circular track 32 from sinking.
[0054] In another specific embodiment:
[0055] Both ends of the second channel 20 are provided with through-holes 21 between them and the first channel 10. The silicon water in the second channel 20 can be guided into the first channel 10 through the through-holes 21 to solve the problem of insufficient capacity of the second channel 20 in the event of a large amount of silicon water leakage.
[0056] Preferably, the first ditch 10 and the second ditch 20 are at the same height, and the through opening 21 is close to the bottom of the first ditch 10 and the second ditch 20. A steel reinforcement foundation is set above the through opening 21 to prevent the track 32 from sinking.
[0057] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
