Abstract
Description
Technical Field
[0001] This utility model relates to the field of burner technology, and in particular to a flow plate baking burner device. Background Technology
[0002] In industrial production, the flow tray is a key piece of equipment for conveying high-temperature melt. The quality of the preheating and baking of its lining directly affects production efficiency and product quality. The lining of the flow tray is mostly made of refractory materials. If the preheating is insufficient or uneven, it is easy to cause cracks and spalling due to thermal shock when in contact with high-temperature melt. This will not only shorten the service life of the flow tray, but may also lead to safety hazards such as melt leakage, which will seriously affect the continuity of production.
[0003] The single-nozzle baking device uses a single nozzle to achieve convective heat transfer to preheat the lining of the flow plate. When the device is running, the gas and air enter the device through the air intake structure, mix at the nozzle and ignite to form a flame. In some small-scale metal casting fields, enterprises do not have high requirements for product output and quality standards, and the single-nozzle baking device can meet their basic flow plate preheating needs.
[0004] The current method of preheating the entire lining of the flow channel using a single nozzle during baking requires manual operation, which is inefficient and labor-intensive. Due to the long flow channel, the temperature is insufficient when the fire of a single nozzle reaches the other end, resulting in uneven heating of different parts of the lining and poor preheating effect. Therefore, a flow plate baking burner device is proposed to solve the above problems. Summary of the Invention
[0005] To overcome the above deficiencies, this utility model provides a flow plate baking burner device, which aims to improve the problem of insufficient preheating temperature difference in the flow channel of some existing devices.

[0012] As a further description of the above technical solution:

[0017] 1.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1 to 4 This utility model provides an embodiment of a flow plate baking burner device, including a reducing connector 10 for connecting pipelines of different diameters to ensure stable pressure of gas and air during transportation. A needle valve 9 is fixedly connected to the left side of the reducing connector 10 and installed on the gas and air transportation pipeline. It is an important component for adjusting the air-to-gas ratio. An air inlet connector 1 is fixedly connected to the left side of the needle valve 9, serving as the gas and air inlet, which can stably receive the externally transported medium and orderly transport it to the subsequent structure. The right side of the air inlet connector 1 is fixedly connected to the left side of the needle valve 9, and an adjusting bracket 3 is fixedly connected to the outside of the air inlet connector 1. By turning the knurled screws 11, the position of components such as the air inlet connector 1 on the adjusting frame 3 can be adjusted, thereby realizing the adjustment of the distance between the various structures to adapt to different baking needs. The top of the adjusting frame 3 is threaded with knurled screws 11. The position is fixed by loosening and tightening the knurled screws 11. Tightening the knurled screws 11 can firmly fix the relevant components on the adjusting frame 3, preventing the position from shifting due to vibration and other factors during the operation of the device. The air outlet 2 is fixedly connected to the left side of the air inlet connector 1. The air inlet connector 1 is fixedly connected to the right side of the adjusting frame 3 and the side close to the needle valve 9. The left side of the air outlet 2 is fixedly connected to the right side of the air inlet connector 1.
[0027] Reference Figure 1 Figure 4A valve core sleeve 4 is fixedly connected to the right side of the regulating frame 3 to further control the medium flow rate. Through the synergistic action of the needle valve 9, the mixing ratio of air and gas is effectively adjusted, providing a basis for complete combustion. A connecting pipe 5 is fixedly connected to the right side of the valve core sleeve 4, which is the medium transmission channel. It can stably deliver the medium after being regulated by the valve core sleeve 4 to the right-angle pipe joint 6. A right-angle pipe joint 6 is fixedly connected to the right side of the connecting pipe 5, which changes the medium from horizontal delivery to vertical downward delivery to the nozzle inner core 7. A connecting pipe 5 is fixedly connected to the left side of the right-angle pipe joint 6 and the side close to the valve core sleeve 4. A nozzle inner core 7 is fixedly connected to the bottom of the right-angle pipe joint 6, which is responsible for evenly discharging the delivered gas and air mixture. A nozzle outer sleeve 8 is fixedly connected to the bottom of the nozzle inner core 7 to enhance the baking firepower and prevent the nozzle inner core 7 from being damaged by direct contact with the high-temperature baking area. The top of the nozzle outer sleeve 8 is fixedly connected to the bottom of the nozzle inner core 7. A nozzle inner core 7 is fixedly connected to the top of the nozzle outer sleeve 8 and the side close to the right-angle pipe joint 6.
[0028] Working principle: By adding an adjustment bracket 3 to the air inlet connector 1 and valve core sleeve 4, the adjustment bracket 3 provides an installation base for multiple sets of nozzles. The position is fixed by tightening and loosening the knurled screws 11, and the distance between the nozzles can be adjusted. The needle valve 9 can effectively adjust the air-to-gas ratio between the air inlet connector 1 and the reducer connector 10, and transmit the medium through the outlet nozzle 2 to the connecting pipe 5, then flow through the right-angle pipe connector 6, and finally release combustion from the nozzle core 7 protected by the nozzle outer sleeve 8, achieving the best combustion effect.
[0029] The baking burner device can be arranged in multiple sets and connected to the main pipe. The main pipe, four sets of nozzles and the cover are driven by an electric push rod. The nozzles do not need to be removed every time casting. Each of the four sets of nozzles is linked to the main pipe through a right-angle pipe joint 6, connecting pipe 5 and other structures. Driven by the electric push rod, the position can be adjusted as a whole to align with the baking area of the inner lining of the flow plate, reducing personnel movement, saving time and improving efficiency.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
