Description

Technical Field

[0001] This utility model relates to the field of glass manufacturing technology, and in particular to a sintering gun assembly and a sintering kiln. Background Technology

[0002] With increasingly stringent requirements for defects in substrate glass and carrier glass, furnace temperature control and bubble defects have a direct impact. Therefore, routine maintenance of equipment directly related to temperature is crucial. Current methods for cleaning carbon deposits in the burner lance are generally done manually, periodically by blowing the burner lance to remove carbon deposits. This method has two drawbacks: first, it cannot clean the carbon deposits immediately when they affect the flame; second, manual blowing to remove carbon deposits requires shutting off the gas for a period of time, which may affect the temperature process.

[0003] Therefore, there is an urgent need to design a sintering lance assembly and a sintering kiln to solve the above problems. Utility Model Content

[0004] One objective of this invention is to provide a burner assembly that can automatically clean the carbon buildup in the burner after it reaches a certain level, without stopping the burner's normal operation, thus ensuring no impact on the temperature process and improving the yield rate.

[0005] Another objective of this invention is to provide a sintering kiln that can continuously heat for extended periods without interruption, automatically cleaning carbon deposits in the firing torch, ensuring stable internal sintering temperatures, and improving the yield of glass products.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] The torch assembly includes:

[0008] A flaming gun is fixed to the pool wall, with the first end of the flaming gun facing inwards from the pool wall.

[0009] The sensing component is used to determine whether the carbon deposits inside the burner need to be cleaned.

[0010] The vibrating element is communicatively connected to the aforementioned sensing components and can generate vibrations in the aforementioned cauldron.

[0011] As an optional solution, the sensing component includes a first sensor and a second sensor. The first sensor is used to detect the gas flow rate V1 at the first end, and the second sensor is used to detect the gas flow rate V2 at the second end of the burner. A process setting flow rate value V3 is defined. When (V2-V1) / V3*100% is greater than X%, the vibrating element starts to vibrate.

[0012] As an alternative, 1 ≤ X ≤ 3.

[0013] As an alternative, the vibrating element includes a plurality of piezoelectric ceramics arranged along the extension direction of the burner, and the plurality of piezoelectric ceramics abut against the outer wall of the burner.

[0014] As an optional solution, the above-mentioned burner assembly also includes a cooling component for cooling the above-mentioned sensing component and the above-mentioned vibration component.

[0015] As an alternative, the cooling component has a cooling chamber filled with cooling gas.

[0016] As an alternative, the cooling component surrounds the burner, and the burner assembly also includes a burner brick. The burner brick is embedded in the pool wall, and a groove is formed on the inner side of the burner brick facing the pool wall. Bolts pass through the bottom wall of the groove and lock it to the end face of the cooling component.

[0017] As an alternative, the second end of the aforementioned burner is connected to a gas mixing chamber, which is connected to both a gas pipeline and an auxiliary gas pipeline.

[0018] As an alternative, the diameter of the aforementioned gas-supporting pipeline is 1.3-1.5 times the diameter of the aforementioned gas pipeline.

[0019] The sintering kiln includes the aforementioned lance assembly and sintering chamber, wherein the sintering assembly is fixed to the pool wall of the sintering chamber.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model provides a sintering torch assembly. By setting a vibrating element on the outside of the sintering torch, when the sensing element detects that the carbon deposits inside the sintering torch need to be cleaned, the vibrating element vibrates the sintering torch, causing the carbon deposits inside the sintering torch to be shaken off and discharged with the airflow of the sintering torch. During this process, the sintering torch does not need to stop working, thus not affecting the temperature inside the sintering chamber. Moreover, the cleaning of carbon deposits depends on the sensing element, and the cleaning is timely, which improves the yield of glass products.

[0022] This utility model also provides a sintering furnace, including the aforementioned lance assembly and sintering chamber, with the sintering assembly fixed to the tank wall of the sintering chamber. The aforementioned sintering furnace can perform continuous heating for extended periods without interruption, automatically cleaning carbon deposits on the lance, ensuring stable internal sintering temperatures, and improving the yield of glass products.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0032] This embodiment provides a burner assembly, such as... Figure 1 and Figure 2 As shown, the sintering lance assembly includes a sintering lance 10, a sensing component 20, and a vibrating component 30. The sintering lance 10 is fixed to the pool wall 210, and the first end 11 of the sintering lance 10 faces the inside of the pool wall 210. The pool wall 210 is the cavity wall of the sintering chamber, and the inside of the pool wall 210 refers to the interior of the sintering chamber. The sensing component 20 is used to determine whether carbon deposits need to be cleaned inside the sintering lance 10. The vibrating component 30 is communicatively connected to the sensing component 20 and can generate vibrations to the sintering lance 10.

[0033] The aforementioned sintering lance assembly, by providing a vibrating element 30 on the outside of the sintering lance 10, when the sensing element 20 senses that the carbon deposits inside the sintering lance 10 need to be cleaned, the vibrating element 30 vibrates the sintering lance 10, causing the carbon deposits inside the sintering lance 10 to be shaken off. As the airflow in the sintering lance 10 is discharged, the sintering lance 10 does not need to stop working during this process, thus not affecting the temperature inside the sintering chamber. Moreover, the cleaning of carbon deposits depends on the sensing element 20, and the cleaning is timely, improving the yield of glass products.

[0034] Optionally, such as Figure 1 As shown, the sensing component 20 includes a first sensor 21 and a second sensor 22. The first sensor 21 is used to detect the gas flow rate V1 at the first end 11, and the second sensor 22 is used to detect the gas flow rate V2 at the second end 12 of the burner 10. A process-defined flow rate value V3 is defined. When (V2-V1) / V3*100% is greater than X%, the vibrating element 30 starts to vibrate. Through the above settings, the first sensor 21 and the second sensor 22 monitor the flow rates at the second end 12 (inlet end) and the first end 11 (outlet pipe) of the burner 10 in real time. Since the inlet end of the burner 10 is pressurized, if the outlet end is blocked by carbon deposits, the flow rate at the outlet end will decrease. This helps to determine whether the carbon deposits need to be cleaned, ensuring that enough gas ultimately enters the sintering chamber and avoiding affecting the gas combustion in the sintering chamber.

[0035] Optionally, the first sensor 21 and the second sensor 22 are connected to the vibration element 30 via a host computer 23.

[0036] Optionally, 1 ≤ X ≤ 3. For example, the value of X can be 1, 1.2, 1.4, 1.5, 1.6, 1.8, 2, 2.2, 2.4, 2.6, 2.8, or 3.0.

[0037] Optionally, such as Figure 1As shown, the vibrating element 30 includes a plurality of piezoelectric ceramics 31 arranged along the extension direction of the burner 10, and all the piezoelectric ceramics 31 abut against the outer wall of the burner 10. The piezoelectric ceramics 31 have high heat resistance, which can ensure normal operation during use. The element driving the vibration of the piezoelectric ceramics 31 can be a vibrator or the like, and is not limited here.

[0038] Optionally, such as Figure 1 As shown, the burner assembly also includes a cooling element 40, which is used to cool the sensing element 20 and the vibrating element 30. By providing the cooling element 40, the vibrating element 30 can be cooled in a timely manner, thereby maintaining the operating temperature of the vibrating element 30 between 50℃ and 100℃.

[0039] Optionally, the cooling element 40 has a cooling chamber filled with cooling gas. Optionally, the cooling gas is compressed air, which has a lower refrigeration cost.

[0040] Optionally, the cooling element 40 can simultaneously cool the first sensing element 21 and the second sensing element 22, achieving the effect of cooling multiple parts with one cooling element 40, ensuring that the first sensing element 21 and the second sensing element 22 operate at a suitable temperature, and extending their service life.

[0041] Optionally, such as Figure 1 As shown, the cooling component 40 surrounds the burner 10. The burner assembly also includes a burner brick 50, which is embedded in the pool wall 210. A groove 51 is formed on the inner side of the burner brick 50 facing the pool wall 210. A bolt 60 passes through the bottom wall of the groove 51 and locks itself to the end face of the cooling component 40. Through this arrangement, the cooling component 40 connects with the burner brick 50, providing a larger connection surface for the bolt 60 and securing the burner 10.

[0042] Optionally, an airtight component 52 is provided between the burner brick 50 and the cooling component 40, and the bolt 60 passes through the airtight component 52. The airtight component 52 is a common structure in the burner assembly, which can prevent the flame in the sintering chamber from being drawn back, thereby avoiding the explosion of gas. It will not be described in detail here.

[0043] Optionally, such as Figure 1 and Figure 2 As shown, the second end 12 of the burner 10 is connected to a mixing chamber 70, which is connected to both a gas pipeline 80 and an auxiliary gas pipeline 90. Through this configuration, the mixing chamber 70 can homogenize the gas and auxiliary gas, ensuring more complete combustion of the gas entering the sintering chamber within the burner 10. The auxiliary gas is typically oxygen.

[0044] Optionally, such as Figure 1As shown, the mixing chamber 70 is connected to the burner 10 via a connector 71. Specifically, the connector 71 is a plate-shaped structure with through holes, one side of which is connected to the mixing chamber 70 and the other side is connected to the burner 10.

[0045] Optionally, the diameter of the combustion-supporting gas pipeline 90 is 1.3-1.5 times the diameter of the gas pipeline 80. This results in a higher proportion of combustion-supporting gas, further ensuring the complete combustion of the gas in the sintering chamber.

[0046] This embodiment also provides a sintering furnace, including the aforementioned lance assembly and sintering chamber, with the sintering assembly fixed to the pool wall 210 of the sintering chamber. This sintering furnace can continuously heat for extended periods without interruption, automatically cleaning carbon deposits on the lance 10, ensuring stable sintering temperatures inside, and improving the yield of glass products. Exemplarily, this sintering furnace can be a hybrid oxygen-electric melting furnace; however, other types of glass product sintering furnaces available on the market can also be used, without limitation.
