Detailed Embodiment

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , the present utility model provides a technical solution: a tin liquid level control system for a liquid metal cooling directional solidification furnace, including a mold shell 1, a radiation heater 2, an induction melting device 3, a cold plate 4, a tin liquid tank 5, a first baffle 6, an inlet pipe 7, a second baffle 8, a rack 9, a floating plate 10, a liquid storage tank 11, an overflow pipe 12, a connecting pipe 13, a heating plate 14, a communicating pipe 15, a floating ball 16, a Magnet 1 17, a Magnet 2 18, and an indicating line 19.

[0027] The device of the present utility model has the effect of automatic liquid inlet, specifically as follows:

[0028] Above the mold shell 1, a radiation heater 2 is provided. Above the radiation heater 2, an induction melting device 3 is provided. Below the mold shell 1, a cold plate 4 is provided. The mold shell 1 is arranged inside a tin liquid tank 5. A first baffle 6 is arranged on the outer surface of the mold shell 1, and the first baffle 6 is installed on the inner wall of the tin liquid tank 5. An automatic liquid inlet structure is arranged on the surface of the tin liquid tank 5. The automatic liquid inlet structure drives the floating plate 10 to move by the buoyancy of the tin liquid inside the tin liquid tank 5 to realize the automatic liquid inlet of the device. The automatic liquid inlet structure includes a liquid inlet pipe 7. The liquid inlet pipe 7 is arranged on the side wall of the tin liquid tank 5. A second baffle 8 is rotatably arranged on the inner wall of the tin liquid tank 5. Tooth blocks are arranged on the outer surface of the second baffle 8, and a semicircular opening is arranged on the surface of the second baffle 8. A rack 9 is arranged on one side of the second baffle 8. The rack 9 meshes with the tooth blocks on the outer surface of the second baffle 8. The lower end of the rack 9 is provided with a floating plate 10, and the floating plate 10 is slidably connected to the inner wall of the tin liquid tank 5;

[0029] As Figures 1-4 shown, the liquid tin is stored in the tin liquid tank 5. The upper mold shell 1 is cooled by the cold plate 4, and a temperature gradient in a specific direction is realized by using the radiation heater 2 and the induction melting device 3, so as to complete directional solidification. During the operation of the device, it is necessary to continuously supplement tin liquid into the tin liquid tank 5. Connect the liquid inlet pipe 7 to the tin liquid. At this time, the second baffle 8 completely blocks the liquid inlet pipe 7. The floating plate 10 slides up and down under the drive of the tin liquid in the tin liquid tank 5. When the liquid level drops, the floating plate 10 drops, driving the rack 9 to move downward. The downward movement of the rack 9 drives the second baffle 8 to rotate clockwise to open the liquid inlet pipe 7, and the tin liquid is replenished into the device from the liquid inlet pipe 7. When the liquid level in the tin liquid tank 5 rises, the floating plate 10 rises, driving the rack 9 to rise. The upward movement of the rack 9 drives the second baffle 8 to rotate counterclockwise to block the liquid inlet pipe 7, and the tin liquid stops being replenished into the device.

[0030] This device has the effect of preventing overflow, specifically:

[0031] An anti-overflow structure is arranged on one side of the tin liquid tank 5. The anti-overflow structure uses the storage tank 11 to temporarily store the tin liquid to prevent the tin liquid from overflowing from the upper end of the tin liquid tank 5. The anti-overflow structure includes a storage tank 11. The storage tank 11 is arranged on one side of the tin liquid tank 5. An overflow pipe 12 is arranged at the upper end of the storage tank 11, and the other end of the overflow pipe 12 penetrates through the surface of the tin liquid tank 5. A connecting pipe 13 is arranged at the lower end of the storage tank 11. The other end of the connecting pipe 13 is connected to the tin liquid tank 5, and a valve is arranged inside the connecting pipe 13 to control the opening and closing. A heating plate 14 is arranged inside the storage tank 11;

[0032] As Figures 1-3As shown in the figure, when the molten tin in the molten tin tank 5 is excessive and the liquid level is higher than the overflow pipe 12, the molten tin flows from the overflow pipe 12 into the liquid storage tank 11 for temporary storage. The heating plate 14 in the liquid storage tank 11 is started to keep the liquid storage tank 11 warm and prevent the molten tin from cooling in the liquid storage tank 11. When it is necessary to supplement the molten tin into the molten tin tank 5, the valve at the connecting pipe 13 can be opened to drain the molten tin in the liquid storage tank 11 into the molten tin tank 5.

[0033] This device has the effect of real-time displaying the internal liquid level, specifically as follows:

[0034] A liquid level display structure is arranged on one side of the molten tin tank 5. The liquid level display structure uses a floating ball 16 to real-time display the height of the molten tin liquid level inside the molten tin tank 5. The liquid level display structure includes a communicating pipe 15. The communicating pipe 15 is arranged on one side of the molten tin tank 5, and one end of the communicating pipe 15 communicates with the molten tin tank 5. A floating ball 16 is arranged inside the communicating pipe 15. A magnet one 17 is connected to the upper surface of the floating ball 16, and the magnet one 17 is slidably connected to the inner wall of the communicating pipe 15. A magnet two 18 is arranged on the outer surface of the communicating pipe 15, and an indicating line 19 is arranged on the surface of the magnet two 18;

[0035] As Figure 1 and Figure 2 shown in the figure, the communicating pipe 15 communicates with the molten tin tank 5. Using the principle of the communicating vessel, the liquid level height in the communicating pipe 15 is made consistent with that in the molten tin tank 5. The floating ball 16 moves driven by the molten tin. The movement of the floating ball 16 drives the magnet one 17 to slide up and down on the inner wall of the communicating pipe 15. The magnet one 17 drives the magnet two 18 to slide up and down on the outer surface of the communicating pipe 15. The magnet two 18 drives the indicating line 19 to move. The height of the liquid level in the molten tin tank 5 can be observed in real time by using the indicating line 19.

[0036] Working principle: When using this liquid level control system for the molten tin in the liquid metal cooling directional solidification furnace, the automatic liquid inlet of the device can be realized by using the baffle two 8 on the side wall of the molten tin tank 5. The baffle two 8 is driven by the rack 9. The rack 9 is driven by the floating plate 10 below. The floating plate 10 moves driven by the liquid level in the molten tin tank 5. When the liquid level in the molten tin tank 5 is higher than the overflow pipe 12, the molten tin flows from the overflow pipe 12 into the liquid storage tank 11 for temporary storage, and the flow back to the molten tin tank 5 is controlled by the valve in the connecting pipe 13. The movement of the indicating line 19 on the outer surface of the communicating pipe 15 is driven by the floating ball 16 in the communicating pipe 15 on one side, so that the height of the liquid level in the molten tin tank 5 can be displayed in real time, increasing the overall practicability.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
