Technical Field

[0001] The utility model relates to the technical field of bubble elimination, in particular to a crucible bubble elimination device. Background Art

[0002] During the quartz crucible forming process, due to the extremely high temperature, the liquid inclusions on the quartz surface will absorb and expand, causing bubbles and cracks on the crucible surface, affecting the quality of the crucible. Therefore, isomorphous metal impurities and gas-liquid inclusions are usually considered to be the most important technical indicators of high-purity quartz sand for quartz crucibles. Therefore, in order to maintain the stability of the quality of quartz crucibles, the gas-liquid inclusions in the high-purity quartz sand, the raw material of quartz crucibles, must be controlled at a low level.

[0016] Beneficial effects:

[0017] 1. The utility model is provided with a motor, and the motor is installed on the top of the bottom plate through a support frame in a front and rear mirror-symmetrical manner. The eccentric block is fixed to the outside of the motor shaft by an interlaced manner. A sliding connection is formed between the movable plate and the limit column. The support spring is located between the movable plate and the bottom plate. The top surface of the movable plate contacts the outside of the eccentric block. When the motor drives the eccentric block to rotate, the distance between the outer periphery of the eccentric block and the rotation axis changes in a curve. When the distance between the outer periphery of the eccentric block and the rotation axis increases, the movable plate will move downward with the rotation of the eccentric block and squeeze the support spring. After that, the eccentric block continues to rotate, and the distance between the outer periphery and the rotation axis decreases. The support spring will push the movable plate to reset, and vibration is repeatedly generated in this way, thereby increasing the fluidity of the bubbles in the crucible and causing the bubbles in the crucible to float up quickly.

The utility model provides a limiting ring, wherein a groove engaged with the screw thread is provided inside the limiting ring, and the screw is installed on the outside of the limiting ring in an "X" shape at equal angles with the center of the limiting ring as a reference. A movable connection is formed between the screw and the limiting ring, and the relative distance between the connecting blocks is adjusted by rotating the screw, thereby limiting the crucible mold to the center of the limiting ring to accommodate crucible molds of different sizes. At the same time, the limiting spring can prevent the relative pressure between the limiting block and the crucible mold from being too large, which may cause damage to the crucible mold. This method can expand the scope of application of the device. BRIEF DESCRIPTION OF THE DRAWINGS
