The invention relates to a device for clearing away bubbles in a sapphire crystal melt material and a method for clearing away the bubbles in the sapphire crystal melt material through the device. The device comprises a crucible, a die, a crucible cover, a bubble collector and a high frequency excitation device; the device further comprises a supporting assembly, the supporting assembly is arranged at the bottom end of the crucible, the device for clearing away the bubbles in the sapphire crystal melt material is fixed into a crystal growing furnace through the supporting assembly, a resonance effect is generated on the bubbles on the bubble collector through high frequency vibration, and the bubbles on the bubble collector are forced to break away rapidly and effectively. The device for clearing away the bubbles in the sapphire crystal melt material has the advantages that the resonance effect is generated on the bubbles on the bubble collector through high frequency vibration, and the bubbles on the bubble collector are forced to break away rapidly and effectively and float upward above the liquid level of melt; the bubbles in the raw material can be effectively cleared away, the content of gas in the melt in the crucible is lowered, cleanliness of the raw material in the crucible is guaranteed to the maximum extent, and furthermore quality of finished crystals is improved.
