Description

Technical Field

[0001] The utility model relates to the field of directional solidification furnaces, in particular to a liquid level early warning device for a directional solidification furnace. Background Art

[0002] A directional solidification furnace is a device that uses multidisciplinary knowledge such as thermofluid mechanics, electromagnetism, and materials science to control the solidification of the melt. It can obtain high-quality crystals. Its basic principle is to form a solidification interface in the melt through transient friction heating or electromagnetic induction heating, move the solidification interface to a high-quality crystallization zone, and maintain the solidification interface within a certain range for directional solidification to obtain high-quality, high-purity, and low-impurity crystals.

[0003] The existing directional solidification furnace liquid level warning device lacks a physical monitoring structure when in use, and usually uses a radar sensor to monitor the coolant level. However, due to the influence of high temperature and external uncertain factors, the accuracy of the radar sensor will decrease.

[0004] Therefore, in view of the fact that the above-mentioned existing directional solidification furnace liquid level warning device lacks a physical monitoring structure when in use, the coolant level is usually monitored by a radar sensor. However, due to the influence of high temperature and external uncertain factors, the accuracy of the radar sensor will decrease. A directional solidification furnace liquid level warning device can be designed. By setting a buoyancy ball, when the coolant is filled into the water tank, the buoyancy ball will float upward. During daily use, the coolant gradually depletes, and the buoyancy ball will drop with the liquid level, thereby driving the slide rod to slide downward. The slide rod will drive the first electrode sheet to drop synchronously. After dropping to a certain distance, the first electrode sheet contacts the second electrode sheet, thereby triggering the controller to transmit a signal to the sound and light alarm, prompting the sound and light alarm to sound an alarm, thereby reminding the staff that the coolant remaining in the water tank is too low and needs to be added in time.

[0015] 1. By setting a buoyancy ball, when the coolant is filled into the water tank, the buoyancy ball will float upward. During daily use, the coolant will gradually be consumed, and the buoyancy ball will drop with the liquid level, thereby driving the slide bar to slide downward, and the slide bar will drive the first electrode sheet to drop synchronously.

After dropping to a certain distance, the first electrode sheet 8 contacts the second electrode sheet 9, thereby triggering the controller 10 to transmit a signal to the audible and visual alarm 11, prompting the audible and visual alarm 11 to sound an alarm, thereby reminding the staff that the remaining coolant in the water tank 2 is too low and needs to be added in time.

[0025] See also Figure 1-Figure 5In this embodiment, the outer surface of the base of the sound and light alarm 11 is rotatably connected with a gear ring 15, and a U-shaped rod 16 is installed on the upper surface of the gear ring 15. The inner surface of the U-shaped rod 16 is provided with bristles 17. By providing the gear ring 15, when the gear ring 15 rotates, the U-shaped rod 16 will be driven to rotate synchronously, thereby driving the bristles 17 to wipe the outer surface of the sound and light alarm 11, reducing dust adhesion and ensuring that the sound and light alarm 11 can maintain a high brightness.

The bottom surface of the solidification furnace body 1 is provided with six circumferentially distributed support legs 29, and the bottom surface of the support legs 29 is provided with gaskets 30. By providing gaskets 30, the friction between the bottom of the support legs 29 and the ground can be increased, thereby improving the overall stability of the device.

[0027] During operation, by setting the gear ring 15, when the gear ring 15 rotates, the U-shaped rod 16 will be driven to rotate synchronously, thereby driving the bristles 17 to wipe the outer surface of the sound and light alarm 11, reducing dust adhesion, and ensuring that the sound and light alarm 11 can maintain a high brightness. By setting the drive motor 13, its output end will drive the gear 14 to rotate during operation, and the gear 14 will drive the gear ring 15 meshing with it to rotate, thereby achieving the purpose of automatically cleaning the outer surface of the sound and light alarm 11. By setting the water pump 18, the cold water inside the water tank 2 will be pumped into the water tank 2 during operation. The coolant is introduced into the interlayer of the solidification furnace body 1 through the infusion pipe 19, and flows back to the water tank 2 through the return pipe 20, thereby realizing water circulation cooling. By setting the transparent plate 22, it is convenient for the staff to observe the remaining amount of coolant in the water tank 2 in real time.

[0028] Through the above steps, by setting the buoyancy ball 7, when the coolant is poured into the water tank 2, the buoyancy ball 7 will float upwards. During daily use, the coolant is gradually consumed, and the buoyancy ball 7 will drop with the liquid level, thereby driving the slide bar 5 to slide downward, and the slide bar 5 will drive the first electrode sheet 8 to drop synchronously. After dropping to a certain distance, the first electrode sheet 8 contacts the second electrode sheet 9, thereby triggering the controller 10 to transmit a signal to the sound and light alarm 11, prompting the sound and light alarm 11 to sound an alarm, thereby reminding the staff that the coolant remaining in the water tank 2 is too low and needs to be added in time. This solves the problem that the existing directional solidification furnace liquid level warning device lacks a physical monitoring structure when in use, and usually uses a radar sensor to monitor the coolant level, which is affected by high temperature and external uncertainties, resulting in a decrease in the accuracy of the radar sensor.
