[0044] Please refer to FIG. 1 and FIG. 2, a glass melting device 100, comprising a vibration assembly 10 and a lifting platform 15, the vibration assembly 10 comprising a vibration piece 101 and a driving piece 102, the vibration piece 101 comprising a connecting end matched with the driving piece 102 and a free end opposite to the connecting end.

[0045] The lifting platform 15 can drive the vessel placed thereon to ascend or descend, so that the free end of the vibration piece 101 extends into or out of the vessel, and the driving piece 102 can drive the vibration piece 101 to vibrate when the free end of the vibration piece 101 extends into the vessel. In the present application, when the glass is melted, the vessel is driven to ascend or descend by the lifting platform 15, so that the free end of the vibration piece 101 extends into the vessel, and then the driving piece 102 is controlled to drive the vibration piece 101 to vibrate, so that the end of the vibration piece 101 extending into the vessel can drive the bubbles in the molten glass to escape through vibration, thereby facilitating the preparation of a uniform glass sample without bubbles through subsequent processes. After the glass melting is completed, the driving piece 102 is controlled to stop driving the vibration piece 101, and the vessel is driven to ascend or descend by the lifting platform 15, so that the free end of the vibration piece 101 extends out of the vessel. In this way, the glass melting device 100 has a simple structure and is flexible to use, and the bubbles in the molten glass can be driven to escape through convenient operation, thereby facilitating the preparation of a uniform glass sample without bubbles.

[0046] Based on the glass melting device provided in the embodiments of the present application, the present application provides a glass melting method. Please refer to FIG. 3, the glass melting method comprises steps S10-S40:

[0047] Step S10: placing a vessel on a lifting platform, the vessel being used to store molten glass.

[0048] It should be noted that the molten glass is a glass liquid. The type of the vessel is not limited, for example, it can be a ceramic crucible.

[0049] Step S20: controlling the lifting platform to drive the vessel to ascend, so that the free end of the vibration piece extends into the vessel to a preset length.

[0050] In some embodiments, please refer to FIGS. 1 and 2, when the lifting platform 15 is controlled to drive the vessel to ascend (here, to ascend), so that the free end of the vibration piece 101 extends into the vessel, the lifting platform 15 has a first preset speed. It can be understood that when the glass is melted, the ascending speed of the lifting platform 15 needs to be controlled, and the ascending speed of the lifting platform 15 is ensured to reach the first preset speed, so that the free end of the vibration piece 101 can quickly extend into the molten glass in the vessel, thereby reducing the probability of bringing gas into the molten glass in the process of extending the vibration piece 101 into the molten glass in the vessel.

[0051] The specific value range of the first preset speed is not limited. In some embodiments, please refer to FIGS. 1 and 2, the first preset speed V1 satisfies the condition 30 mm / s (millimeter / second)≤V1≤50 mm / s.

[0052] It should be noted that the specific value range of the first preset speed is obtained through experimental testing, and the experimental testing related parameters, steps, etc. related to the specific value range of the first preset speed are all conventional techniques of those skilled in the art, which will not be repeated here.

[0053] It should be noted that when the glass is melted, the free end of the vibration piece 101 needs to be inserted into the vessel to a preset length to ensure that the vibration piece 101 has sufficient contact area with the molten glass, so that the bubbles in the molten glass can be fully discharged, which is beneficial to improve the quality of glass melting.

[0054] The preset length is related to the diameter of the vibration piece 101 itself. Specifically, when the free end of the vibration piece 101 is inserted into the vessel to the preset length, the distance between the end of the vibration piece 101 away from the driving piece 102 and the bottom of the vessel is a preset multiple of the diameter of the vibration piece 101 itself. In some embodiments, referring to FIGS. 1 and 2, the preset multiple satisfies the condition: 2≤preset multiple≤5.

[0055] That is, when the free end of the vibration piece 101 is inserted into the vessel to the preset length, the distance between the end of the vibration piece 101 away from the driving piece 102 and the bottom of the vessel is 2 to 5 times the diameter of the vibration piece 101 itself, so that the vibration piece 101 has sufficient contact area with the molten glass, and the bubbles in the molten glass can be fully discharged, which is beneficial to improve the quality of glass melting.

[0056] Step S30: controlling the driving piece to drive the vibration piece to vibrate for a preset time.

[0057] In some embodiments, the frequency at which the driving piece drives the vibration piece to vibrate is 30 Hz to 150 Hz, preferably 60 Hz to 120 Hz. It can be understood that when the frequency at which the driving piece drives the vibration piece to vibrate is 60 Hz to 120 Hz, the vibration rod 1011 ensures the removal of gas in the molten glass.

[0058] It can be understood that during the process of melting the glass, if the driving piece 102 drives the vibration piece 101 to vibrate for too long, it will cause the molten glass to generate bubbles again, and if the driving piece 102 drives the vibration piece 101 to vibrate for too short, it will cause the bubbles in the molten glass to be unable to be fully discharged. Therefore, the preset time in the present application can ensure that the vibration piece 101 fully discharges the bubbles in the molten glass and avoids the generation of bubbles in the molten glass again.

[0059] The specific value range of the preset time is not limited. In some embodiments, referring to FIGS. 1 and 2, the preset time is t, and the preset time t satisfies the condition: 20s≤t≤30s, or 30s

[0060] It should be noted that the specific value range of the preset time is obtained through experimental testing, and the parameters, steps, etc. related to the experimental testing of the specific value range of the preset time are all conventional techniques for those skilled in the art, and are not described here.

[0061] Step S40: controlling the lifting platform to lower the vessel so that the free end of the vibration piece extracts the vessel.

[0062] In some embodiments, referring to FIGS. 1 and 2, when the lifting platform 15 is controlled to be able to lower the vessel (here, to lower the vessel), the free end of the vibration piece 101 extracts the vessel, the lifting platform 15 has a second preset speed. It can be understood that when the glass is being melted, the lifting speed of the lifting platform 15 needs to be controlled and the lifting speed of the lifting platform 15 needs to be ensured to reach the second preset speed, so that the free end of the vibration piece 101 can slowly extract the molten glass in the vessel, so as to avoid the secondary bubbles caused by the molten glass not filling the cavity extracted by the vibration piece 101 in time.

[0063] The specific value range of the second preset speed is not limited. In some embodiments, referring to FIGS. 1 and 2, the second preset speed V2 satisfies the condition 10 mm / s≤V2≤20 mm / s.

[0064] It should be noted that the specific value range of the second preset speed is obtained through experimental testing, and the parameters, steps, etc. related to the experimental testing of the specific value range of the second preset speed are all conventional techniques for those skilled in the art, and are not described here.

[0065] In some embodiments, referring to FIGS. 1 and 2, the vibration piece 101 includes at least one vibration rod 1011 and a high-temperature corrosion prevention piece 1015, and the end of each vibration rod 1011 away from the driving piece 102 is defined as a heated end 1013; wherein the outer periphery of each heated end 1013 is covered with a high-temperature corrosion prevention piece 1015.

[0066] It can be understood that solid glass needs to be above 1200℃ to be melted into molten glass, and the heated end 1013 of the vibration rod 1011 needs to be inserted into the molten glass, which needs to withstand high temperature and is prone to damage. Therefore, the outer periphery of the heated end 1013 of the vibration rod 1011 is covered with a high-temperature corrosion prevention piece 1015, which isolates the temperature of the molten glass and the corrosion of the molten glass to the vibration rod 1011, thereby improving the service life of the vibration rod 1011.

[0067] It can be understood that, in the embodiment in which the vibrating member 101 comprises the vibrating rod 1011 and the high-temperature corrosion-resistant member 1015, the diameter of the vibrating member 101 itself is twice the sum of the radius of the vibrating rod 1011 and the wall thickness of the high-temperature corrosion-resistant member 1015.

[0068] The specific material of the high-temperature corrosion-resistant member 1015 is not limited. In some embodiments, referring to FIGS. 1 and 2, the material of the high-temperature corrosion-resistant member 1015 is a metal material, such as platinum, rhodium, platinum, gold, etc.

[0069] The specific connection mode of the high-temperature corrosion-resistant member 1015 and the vibrating rod 1011 is not limited. In some embodiments, referring to FIGS. 1 and 2, the high-temperature corrosion-resistant member 1015 is partially embedded in the vibrating rod 1011 and is buckled with the vibrating rod 1011. In this way, the disassembly and assembly of the high-temperature corrosion-resistant member 1015 and the vibrating rod 1011 can be facilitated, and the machining and replacement of the high-temperature corrosion-resistant member 1015 and the vibrating rod 1011 can be facilitated, thereby reducing the subsequent maintenance and replacement time and further improving the production efficiency.

[0070] In some embodiments in which the material of the high-temperature corrosion-resistant member 1015 is a metal material such as platinum, rhodium, platinum, gold, etc., the vibrating rod 1011 is formed with a mounting groove 1014, and the high-temperature corrosion-resistant member 1015 is formed with a matching part for being embedded in the mounting groove 1014 and buckled with the mounting groove 1014. It can be understood that, when the material of the high-temperature corrosion-resistant member 1015 is a metal material such as platinum, rhodium, etc., the high-temperature corrosion-resistant member 1015 has good ductility, and the matching part buckled with the mounting groove 1014 can be easily machined.

[0071] In some embodiments, referring to FIGS. 1 and 2, each vibrating rod 1011 is a hollow structure, and each vibrating rod 1011 has a first preset wall thickness T1.

[0072] It can be understood that the hollow structure of the vibrating rod 1011 is conducive to cost saving and can reduce the structural self-weight of the vibrating rod 1011, thereby reducing the energy consumption required when the driving member 102 drives the vibrating rod 1011 to vibrate. The present application ensures that the vibrating rod 1011 has the first preset wall thickness T1, so as to ensure that the vibrating rod 1011 can better transmit the vibration frequency generated by the driving member 102, thereby ensuring the removal effect of the gas in the molten glass.

[0073] The specific value range of the first preset wall thickness T1 is not limited. In some embodiments, referring to FIGS. 1 and 2, the first preset wall thickness T1 satisfies the condition: 0.5 mm (millimeter) ≤ T1 ≤ 10 mm.

[0074] It should be noted that the specific value range of the first preset wall thickness T1 is obtained through experimental testing, and the parameters and steps related to the experimental testing of the specific value range of the first preset wall thickness T1 are all conventional techniques of those skilled in the art, which will not be repeated here.

[0075] In some embodiments, the high-temperature corrosion prevention member 1015 is wrapped around the outer periphery of the heated end 1013 and has a second preset wall thickness T2 in the radial direction of the vibration rod 1011.

[0076] It can be understood that the second preset wall thickness T2 can isolate the temperature of the molten glass and the corrosion of the molten glass to the vibration rod 1011, so as to improve the service life of the vibration rod 1011.

[0077] The specific value range of the second preset wall thickness T2 is not limited. In some embodiments, referring to FIGS. 1 and 2, the second preset wall thickness T2 satisfies the condition: 0.2mm≤T2≤1mm.

[0078] It should be noted that the specific value range of the second preset wall thickness T2 is obtained through experimental testing, and the parameters and steps related to the experimental testing of the specific value range of the second preset wall thickness T2 are all conventional techniques of those skilled in the art, which will not be repeated here.

[0079] In some embodiments, referring to FIGS. 1 and 2, each vibration rod 1011 is a columnar structure, and each vibration rod 1011 has a preset outer diameter R.

[0080] It can be understood that the preset outer diameter R of the vibration rod 1011 can affect the transmission frequency of the vibration and the contact area between the vibration rod 1011 and the molten glass. Specifically, when the preset outer diameter R of the vibration rod 1011 is too small, the contact area between the vibration rod 1011 and the molten glass is small, which will affect the exhaust efficiency. When the preset outer diameter R of the vibration rod 1011 is too large, the vibration transmission effect of the vibration rod 1011 will be weakened, which will affect the exhaust efficiency.

[0081] The present application ensures that the vibration rod 1011 has a preset outer diameter R, so as to ensure that the vibration rod 1011 can better transmit the vibration frequency generated by the driving member 102, thereby ensuring the exclusion effect and efficiency of the gas in the molten glass.

[0082] The specific value range of the preset outer diameter R is not limited. In some embodiments, referring to FIGS. 1 and 2, the preset outer diameter R satisfies the condition: 2mm≤R≤60mm.

[0083] It should be noted that the specific value range of the preset outer diameter R is obtained through experimental testing, and the experimental testing related parameters, steps, etc. related to the specific value range of the preset outer diameter R are all the conventional techniques of those skilled in the art, which will not be repeated here.

[0084] In some embodiments, referring to FIGS. 1 and 2, the number of the vibration rods 1011 is multiple, each vibration rod 1011 is arranged spaced apart from each other, and the preset interval T3 between the adjacent two vibration rods 1011 satisfies the condition: 2R≤T3≤5R. Preferably, the preset interval T3 satisfies the condition: 3R≤T3≤4R.

[0085] In some embodiments, referring to FIGS. 1 and 2, the glass melting device 100 further comprises a cooling member 12, which is arranged around the periphery of the lifting platform 15 and jointly defines a heat insulation space 13 with the lifting platform 15. It can be understood that the vessel is placed in the heat insulation space 13, and the cooling member 12 can block the high temperature emitted by the molten glass in the vessel in the heat insulation space 13 to avoid affecting the external environment.

[0086] The specific material of the cooling member 12 is not limited, for example, the material of the cooling member 12 can be corundum high-temperature-resistant, mullite temperature-resistant brick, ceramic fiber plate, etc. In some embodiments, referring to FIGS. 1 and 2, the material of the cooling member 12 is a ceramic fiber plate. It can be understood that the ceramic fiber has good heat insulation performance and low cost, which is beneficial to cost saving.

[0087] In some embodiments, referring to FIGS. 1 and 2, the end of each vibration rod 1011 connected with the driving member 102 is defined as a cooling end 1012, and a heated end 1013 penetrates through the cooling member 12 and extends into the heat insulation space 13, and the driving member 102 and the cooling end 1012 are both located outside the heat insulation space 13. It can be understood that the cooling member 12 can block the high temperature emitted by the molten glass to avoid damage to the driving member 102 under high temperature, and the cooling member 12 can cool the vibration rod 1011 to reduce the temperature of the cooling end 1012, ensuring the normal connection and operation of the cooling end 1012 and the driving member 102.

[0088] In some embodiments, referring to FIG. 1, the glass melting device 100 further comprises a connecting member 16 connected between the driving member 102 and the vibration rod 1011.

[0089] Specifically, one end of the connecting piece is matched with the driving piece 102, and the other end is matched with the cooling end 1012 of the vibration rod 1011. When the glass is melted, the driving piece 102 needs to be controlled to be turned on, and the driving piece 102 can drive the vibration piece 101 to vibrate through the connecting piece 16, so that the end of the vibration piece 101 inserted into the container can expel the bubbles in the molten glass through vibration, thereby facilitating the preparation of a uniform glass sample without bubbles through subsequent processes.

[0090] In some embodiments, referring to FIGS. 1 and 2, the glass melting device 100 further comprises a fixing piece 14, which is arranged on the side of the cooling piece 12 away from the heat insulation space 13 and is used to fixedly connect the vibration piece 101 and the cooling piece 12. In this way, the stable installation of the vibration piece 101 can be ensured.

[0091] The specific material of the fixing piece 14 is not limited. In some embodiments, referring to FIGS. 1 and 2, the fixing piece 14 is ceramic. It can be understood that ceramic has good heat insulation performance and is cheap, which is beneficial to cost saving, and the fixing piece 14 is connected with the vibration piece 101, which can cool the vibration rod 1011 to reduce the temperature of the cooling end 1012 and ensure the normal connection and operation of the cooling end 1012 and the driving piece 102.

[0092] It should be noted that the fixing piece 14 is ceramic, which means that the material of the fixing piece 14 is ceramic.

[0093] In some embodiments, referring to FIGS. 1 and 2, after the end of the vibration piece 101 away from the driving piece 102 is inserted into the container, the driving piece 102 is controlled to drive the vibration piece 101 to vibrate for a preset time.

[0094] The application will be further described in detail below by way of specific examples.
