[0026] All terms used in the present disclosure have the same meanings as those understood by those of ordinary skill in the art to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.

[0027] The technologies, methods and equipment known to ordinary technicians in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods and equipment should be considered as part of the specification. As mentioned in the above background technology, during the use of the burner of the glass kiln, since the burner is in a high temperature state, the burner nozzle is prone to deformation, thereby affecting the flame spraying of the burner. Therefore, in order to avoid the problem of deformation of the burner nozzle, the burner needs to be cooled during the use of the burner. Based on this, the inventor of the present application provides a burner device and a glass kiln for a glass kiln in one or more embodiments. The burner device of the glass kiln swirls the gas therein through a vortex chamber to form high-temperature gas and low-temperature gas. The low-temperature gas flows through the cooling chamber to cool the gun body, thereby avoiding the problem of deformation of the gun mouth due to excessive temperature affecting the flame spraying. It is believed that it can solve one or more problems in the prior art.

[0028] In view of the above-mentioned technical problems, the utility model provides a burning gun device for a glass kiln, such as Figure 1As shown, it includes: a vortex chamber 1, which is used to vortex the gas discharged therein to form high-temperature gas and low-temperature gas, and the vortex chamber 1 includes an air inlet 2, a first exhaust port 3 and a second exhaust port 4; a gun body 5, a gun mouth 9 is opened on the gun body 5, and the first exhaust port 3 is connected with the gun body 5 to discharge the high-temperature gas in the vortex chamber 1 into the gun body 5; a cooling chamber 6, the cooling chamber 6 is covered on the gun body 5, the vortex chamber 1 is connected with the cooling chamber 6 through the second exhaust port 4 to discharge the low-temperature gas into the cooling chamber 6 for cooling the gun body 5, and the air outlet of the cooling chamber 6 is connected with the gun body 5 to discharge the low-temperature gas in the cooling chamber 6 into the gun body 5 and mix it with the high-temperature gas to form a flame at the gun mouth 9.

[0029] Specifically, after the gas enters the vortex cavity 1 through the air inlet 2, the gas forms a free vortex in the vortex cavity 1. The rotational angular velocity of the free vortex increases as it approaches the center. Due to the different angular velocities, there is friction between the layers of the free vortex. The angular velocity of the airflow in the center is the highest. The friction causes energy to be transferred to the gas airflow in the outer layer with a lower angular velocity. The gas airflow in the middle layer loses energy and has low kinetic energy, so the speed and temperature are reduced, thereby forming low-temperature gas. The low-temperature gas is discharged into the cooling cavity 6 through the second exhaust port 4. During the flow of the low-temperature gas in the cooling cavity 6, heat exchange occurs with the gun body 5, thereby cooling the gun body 5, thereby avoiding the problem of deformation of the gun mouth 9 and affecting the flame ejection of the gun mouth 9. The outer layer of the gas airflow in the vortex cavity 1 gains momentum and increases kinetic energy. At the same time, it rubs against the turbine tube wall, converting part of the kinetic energy into heat energy, thereby forming high-temperature gas. The high-temperature gas is discharged into the gun body 5 through the first exhaust port 3 and mixed with the low-temperature gas that has completed heat exchange in the cooling cavity 6 in the gun body 5, and then forms a flame at the gun mouth 9. Furthermore, a control valve may be provided on the vortex chamber 1, and the flow rate and temperature of the high-temperature fuel gas and the low-temperature fuel gas may be controlled by the control valve.

[0030] Compared with the prior art, the present application discloses a glass kiln burning gun device, which processes the fuel gas therein through a vortex chamber 1 to form high-temperature fuel gas and low-temperature fuel gas. The low-temperature fuel gas flows through a cooling chamber 6 to cool the gun body 5, thereby avoiding the problem of deformation of the gun muzzle 9 due to excessive temperature, which affects the flame spraying.

[0031] In some embodiments, a plurality of baffles are provided in the cooling chamber 6, and the plurality of baffles divide the cooling chamber 6 into a plurality of interconnected cavities to extend the flow of the low-temperature gas in the cooling chamber 6. The cooling chamber 6 is formed into a plurality of interconnected spaces by the plurality of baffles, thereby extending the path through which the low-temperature gas flows in the cooling chamber 6, and improving the cooling effect on the gun body 5. Furthermore, the plurality of baffles may be staggeredly provided in the cooling chamber 6, so as to further extend the flow of the low-temperature gas in the cooling chamber 6, thereby further improving the cooling effect on the gun body 5.

[0032] In some embodiments, Figure 1 As shown, the mixing chamber 7 is also included, and the mixing chamber 7 is communicated with the first exhaust port 3 and the exhaust port of the cooling chamber 6. The exhaust port of the mixing chamber 7 is communicated with the gun body 5 to discharge the high-temperature gas and the low-temperature gas mixed in the mixing chamber 7 into the gun body 5. The high-temperature gas and the low-temperature gas can be mixed through the mixing chamber 7 and then provided to the gun body 5, avoiding the problem of unstable flame at the gun muzzle 9 caused by directly providing the high-temperature gas and the low-temperature gas to the gun body 5.

[0033] In some embodiments, the outer wall of the cooling chamber 6 is coated with a high temperature resistant heat-insulating material to prevent the low temperature gas in the cooling chamber 6 from exchanging heat with the environment. By coating the outer wall of the cooling chamber 6 with the high temperature resistant heat-insulating material, the problem of heat exchange between the low temperature gas in the cooling chamber 6 and the environment is avoided, the cooling effect of the gun body 5 is ensured, and energy saving is achieved. Furthermore, the high temperature resistant heat-insulating material needs to be a non-combustible material.

[0034] In some embodiments, a control valve is provided on the air inlet 2 to control the flow rate of the gas discharged into the vortex chamber 1. The flow rate of the gas discharged into the vortex chamber 1 can be controlled by the control valve, so that the flow rate of the gas provided to the gun body 5 and the flow rate of the low-temperature gas provided to the cooling chamber 6 can be controlled to ensure the cooling effect of the low-temperature gas on the gun body 5 and to ensure that the gas at the gun muzzle 9 burns stably.

[0035] In some embodiments, a gas supply mechanism is also included, which is communicated with the gas inlet 2 to provide gas for the vortex chamber 1. The gas supply mechanism ensures the gas source of the burner device.

[0036] In some embodiments, the gas supply mechanism is connected to the air inlet 2 through a retractable gas supply pipe 8. The retractable gas supply pipe 8 enables the gas supply mechanism to provide gas to the vortex chamber 1, and also facilitates the adjustment of the distance between the gun body 5 and the gas supply mechanism, which is convenient for use and ensures safety.

[0037] In some embodiments, a flow meter is provided on the gas supply pipe 8 to monitor the flow rate of the gas in the gas supply pipe 8. The flow rate of the gas discharged into the vortex chamber 1 can be monitored in real time by the flow meter.

[0038] On the other hand, the present disclosure also provides a glass kiln, including a main body and the above-mentioned burning gun device of the glass kiln, wherein the muzzle 9 of the burning gun device extends into the inside of the side wall of the main body for auxiliary heating of the glass raw materials in the main body. Specifically, the glass kiln includes a main heating mechanism, and when the heating amount of the main heating mechanism cannot meet the needs of the glass kiln, the burning gun device is started to auxiliary heat the glass kiln. The burning gun device cools the gun body 5 through the low-temperature combustion gas formed in the vortex chamber 1 and the flow of the low-temperature combustion gas in the cooling chamber 6, thereby avoiding the problem of flame spraying caused by deformation of the muzzle 9 due to excessive temperature, thereby ensuring the stability of the auxiliary heating of the burning gun device.

[0039] In some embodiments, the burner device includes a plurality of burner devices, and the gun ports 9 of the plurality of burner devices are spaced and distributed on the side wall of the body. The plurality of burner devices further ensures the auxiliary heating effect.
