Description

TECHNICAL FIELD

[0001] The utility model relates to gas melting furnace technical field especially relates to a heating structure of gas melting furnace. BACKGROUND

[0002] The gas melting furnace is provided with a gas nozzle that can spray fire for a long time, and the end of the gas nozzle will heat up due to the flame, which will shorten the service life of the gas nozzle and increase the replacement frequency of the gas nozzle. In addition, the inner container of the current gas melting furnace has a fixed structure, and the gas nozzle sprays gas in one direction. Therefore, the current gas melting furnace has low heating and melting efficiency for objects. Moreover, the current gas melting furnace relies on visual inspection to detect the leakage of the heating fluid, which not only increases labor, but also increases the energy consumption of the leakage.

The gas nozzle and the heat dissipation sleeve are installed on the inside of the mounting hole. The heat dissipation sleeve cools the gas nozzle. The heat dissipation sleeve is provided with a heat dissipation groove. Specifically, when the cooling gas enters the heat dissipation sleeve, the cooling gas circulates inside the heat dissipation sleeve and is then discharged outward. The cooling gas effectively cools the gas nozzle during the flow process, avoiding the heating of the end of the gas nozzle due to the flame. The service life of the gas nozzle will be shortened when it heats up for a long time.

[0026] Finally, the connecting rod 113 is fixedly connected to the mounting shell 111 and located on the side of the mounting shell 111 away from the limiting block 112, and connected to the limiting block 112; the spring 114 is sleeved on the outside of the connecting rod 113, and both ends of the spring 114 abut against the limiting block 112 of the mounting shell 111 respectively; the lever 115 is fixedly connected to the limiting block 112 and located on the side of the limiting block 112 away from the connecting rod 113; the connecting rod 113 is bolted to the mounting shell 111, and the other end of the connecting rod 113 is bolted to the limiting block 112. 3 is a telescopic rod. The connecting rod 113 prevents the limiting block 112 from sliding out of the mounting shell 111. The spring 114 is sleeved on the outside of the connecting rod 113, and the two ends of the spring 114 abut against the limiting block 112 and the mounting shell 111 respectively. The elastic force of the spring 114 drives the limiting block 112 to move upward, thereby making the limiting block 112 engage with the rack 110. The lever 115 is bolted to the connecting rod 113. The lever 115 drives the limiting block 112 to move downward, thereby enabling the rack 110 to move, and thus driving the drive ring 108 to rotate.

[0027] Using the heating structure of a gas-fired furnace in this embodiment, when the angle of the nozzle 104 needs to be adjusted, the lever 115 is first moved to disengage the limiting block 112 from the rack 110. At this time, the sliding block 109 drives the rack 110 to move, which in turn drives the drive ring 108 to move. The drive ring 108 drives the rotating block 103 to rotate via the rotating shaft 102, thereby changing the angle of the nozzle 104. After adjusting the angle, the lever 115 is released, and the spring 114 drives the limiting block 112 to move upward and engage with the rack 110, thereby fixing the rack 110 and keeping the nozzle 104 at the specified angle. This allows for adjustment of the nozzle 104's angle to heat different heights of the placement sleeve, thus improving the practicality of the equipment.
