[0002] With the advancement of science and technology and market demand, high-strength microcrystalline glass has become the mainstream product in the glass market. The heat treatment process of glass is controlled by glass crystallization equipment to arrange the internal atoms or molecules in a regular manner, thereby forming microcrystalline glass with high strength, high wear resistance and low thermal expansion coefficient. It is also called glass ceramics. This type of equipment plays an increasingly important role in the field of glass manufacturing. Therefore, we propose a glass crystallization device.

[0003] The prior art also has the following defects during use: When the glass crystallization device in the prior art performs a crystallization process on the glass, it is necessary to precisely control the temperature of the glass. Not only does it need to drastically adjust the temperature of the glass, but it is also necessary to control the speed of temperature change to ensure the crystallization effect of the glass. Traditional glass crystallization equipment can only regulate the overall temperature of the glass by adjusting the ambient temperature of the internal chamber of the equipment, and thus cannot ensure the uniformity of heating or cooling the glass as a whole, which can easily lead to poor local crystallization effect of the glass and affect the quality of the glass crystallization process.

[0004] In view of this, we propose a glass crystallization device to solve the existing problems. Summary of the invention

The crystallization chamber 2 can provide a space for placing the glass, so that it is convenient to crystallize the glass by adjusting the temperature inside the crystallization chamber 2. After the resistance wire 202 is energized, it can generate heat to heat the inside of the crystallization chamber 2, so that the glass is heated up and the glass crystallization is promoted. The flow guide tube 203 can be connected to the connecting pipe 206, so that the refrigerant enters the inside of the flow guide tube 203. When the glass needs to be cooled during the crystallization process, the heat inside the crystallization chamber 2 is absorbed by the flow guide tube 203, the ambient temperature inside the crystallization chamber 2 is lowered, and the temperature change speed is controlled in cooperation with the resistance wire 202, thereby improving the effect of glass crystallization.

The threaded sleeve 302 can cooperate with the threaded rod 301. When the threaded rod 301 rotates, the height of one end of the electric telescopic rod 303 is adjusted through the vertical movement of the threaded sleeve 302, and then the position and inclination angle of the heat-conducting ring 306 are adjusted in conjunction with the extension and retraction of the electric telescopic rod 303.

At the same time, the heat-conducting ring 306 absorbs the heat inside the crystallization chamber 2, so that its own temperature rises. When the glass is continuously heated and reaches a specified temperature, the electric power of the resistance wire 202 is controlled to maintain the ambient temperature inside the crystallization chamber 2.
