Description

Technical Field

[0001] This utility model relates to the field of industrial silicon production equipment technology, and more specifically to a silicon liquid casting system for a submerged arc furnace. Background Technology

[0002] A submerged arc furnace, also known as an electric arc furnace or resistance furnace, is a high-energy-consuming equipment used for smelting ferroalloys and primary industrial products such as calcium carbide. The production of industrial silicon by smelting in an electric furnace involves reducing silicon ore with a carbonaceous reducing agent to produce elemental silicon. The molten silicon produced by the submerged arc furnace is discharged through the furnace opening into a ladle, which is then transferred to the oxygen blowing refining station for refining. After refining, it is transferred to the casting station.

[0003] During the casting process, the main hook of the overhead crane is used to lift the ladle by hooking it at the ladle opening. Then, the auxiliary hook is used to hook the lifting lugs at the bottom of the ladle and tilt it around the lifting point of the main hook to pour the molten silicon into the silicon ingot mold. However, in the existing technology, before the overhead crane lifts the ladle, it is necessary to frequently assist manually in attaching the main hook and auxiliary hook to the corresponding positions on the ladle, which is highly dangerous and poses safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a silicon liquid casting system for a submerged arc furnace, which improves operational safety and eliminates the safety hazards caused by frequent manual assistance in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A silicon liquid casting system for a submerged arc furnace includes a track and two bases. A support frame is mounted above the two bases. A support frame and a tilting cylinder are located between the support frame and the bases. The bottom of the support frame is fixedly connected to the base, and the top of the support frame is rotatably connected to the support frame. Both ends of the tilting cylinder are hinged to the support frame and the base, respectively. The track is parallel to the two bases. A trolley is slidably connected to the track, and a ladle is placed on the trolley. An arc-shaped support groove adapted to the outer wall of the ladle is provided on the side of the support frame near the ladle. Horizontal columns are horizontally arranged on both sides of the ladle. Two mounting plates are symmetrically arranged at the bottom of the support frame. A slot is provided on the side of the mounting plate near the horizontal column, and the slot is directly opposite and adapted to the horizontal column.

[0007] Furthermore, the upper surface of the mobile trolley is provided with a positioning slot, and the table bag is placed in the positioning slot.

[0008] Furthermore, an electric telescopic rod is installed on the mounting plate, and a limit baffle is fixedly connected to the drive end of the electric telescopic rod. The limit baffle is located at the opening of the slot.

[0009] Furthermore, a limiting circular plate is fixedly connected to the end of the cross column away from the platform, and the diameter of the limiting circular plate is larger than the diameter of the cross column.

[0010] Furthermore, a trolley positioning baffle is fixedly connected between the two bases, and the trolley positioning baffle is positioned directly opposite the mobile trolley.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This application utilizes the arc-shaped support groove of the support frame to effectively support and position the ladle, ensuring its stability during the casting process. The horizontal column engages with the slot on the mounting plate, further strengthening the connection stability between the ladle and the support frame, ensuring that the ladle will not detach during tilting and providing a reliable guarantee for the smooth casting of molten silicon. Stable tilting is achieved through the drive of the tilting cylinder, replacing the traditional method of tilting the ladle around the main hook of the overhead crane. This avoids the dangerous process of manually assisting in hooking the auxiliary hook, improves operational safety, and eliminates the safety hazards caused by frequent manual assistance in existing technologies.

[0016] like Figure 1 and Figure 2As shown, a silicon liquid casting system for a submerged arc furnace includes a track 1 and two bases 2. A support frame 3 is provided above the two bases 2. A support frame 4 and a tilting cylinder 5 are provided between the support frame 3 and the base 2. The bottom of the support frame 4 is fixedly connected to the base 2, and the top of the support frame 4 is rotatably connected to the support frame 3. The two ends of the tilting cylinder 5 are respectively hinged to the support frame 3 and the base 2. The track 1 is arranged parallel between the two bases 2. A moving trolley 6 is slidably connected to the track 1. A platform 7 is placed on the moving trolley 6. An arc-shaped support groove 301 adapted to the outer wall of the platform 7 is opened on the side of the support frame 3 near the platform 7. Horizontal columns 8 are arranged on both sides of the platform 7. Two mounting plates 9 are symmetrically arranged at the bottom of the support frame 3. A slot 901 is opened on the side of the mounting plate 9 near the horizontal column 8. The slot 901 is set directly opposite the horizontal column 8 and adapted to the horizontal column 8.

[0017] The upper surface of the mobile trolley 6 is provided with a positioning slot 601, and the table bag 7 is placed in the positioning slot 601.

[0018] An electric telescopic rod 10 is installed on the mounting plate 9. The driving end of the electric telescopic rod 10 is fixedly connected to a limiting baffle 11, which is located at the opening of the slot 901. After the crossbar 8 of the ladle 7 is inserted into the slot 901, the electric telescopic rod 10 can drive the limiting baffle 11 to move to the opening of the slot 901 to limit the crossbar 8 and prevent it from accidentally sliding out of the slot 901. This setting further enhances the reliability of the connection between the ladle 7 and the support frame 3. Especially during the tilting process of the support frame 3, it can effectively prevent the ladle 7 from detaching from the support frame 3 due to changes in force, improve the safety and stability of the casting process, realize automatic limiting protection for the ladle 7, reduce the manual inspection and fixing links, and improve the automation level of the system.

[0019] The end of the horizontal column 8 away from the platform 7 is fixedly connected to a limiting circular plate 12, the diameter of which is larger than the diameter of the horizontal column 8.

[0020] A trolley positioning baffle 13 is fixedly connected between the two bases 2, and the trolley positioning baffle 13 is positioned directly opposite the mobile trolley 6.

[0021] Working principle:

[0022] First, the smelted molten silicon is loaded into a ladle 7. Using a sliding trolley 6 on track 1, the ladle 7 is transferred to the support frame 3 between the two bases 2. When the trolley 6 reaches the predetermined position, the trolley positioning baffle 13 positions the trolley 6, ensuring it stops accurately. At this point, the horizontal columns 8 on both sides of the ladle 7 are aligned with the slots 901 on the bottom mounting plate 9 of the support frame 3. Because the arc-shaped support groove 301 on the side of the support frame 3 closest to the ladle 7 matches the outer wall of the ladle 7, the ladle 7 is stably supported on the support frame 3, and the horizontal columns 8 are engaged in the slots 901. Next, the tilting cylinder 5 is activated. The piston rod of the tilting cylinder 5 extends and retracts, driving the support frame 301 to tilt around the rotating connection point at the top of the support frame 4, thereby tilting the ladle 7 and pouring the molten silicon into the silicon ingot mold. After casting is completed, the tilting cylinder 5 reverses its movement, restoring the support frame 3 to a horizontal position. Then, the moving trolley 6 removes the empty platform 7 from the support frame 3, completing one casting operation.

[0023] This invention, through the coordinated operation of its components, eliminates the dangerous manual intervention required by traditional overhead cranes to frequently engage the main and auxiliary hooks, achieving automatic transfer, positioning, and tipping of the platform baggage. This significantly reduces safety risks for workers during operation. It ensures stability and accuracy during the tipping process, reduces production accidents and quality problems caused by human error or inaccurate equipment positioning, minimizes manual intervention, improves production efficiency, and lowers production costs.
