[0002] Currently, in related technologies, when heat-treating workpieces, the workpiece needs to be placed in a heating furnace; then, heat is injected into a radiant tube, and the workpiece is heated by radiating heat through the radiant tube.

By having two first radiant tubes heat the workpiece placed on multiple transmission rollers from above, and a second radiant tube heats the workpiece placed on multiple transmission rollers from below, all-around heating of the workpiece is achieved. This allows the workpiece to reach the preset temperature in the shortest possible time, improving product efficiency. When the workpiece is thick, the first and second radiant tubes heat it from both the top and bottom directions to avoid uneven heating of the upper and lower parts of the workpiece, improving the heat treatment effect and thus enhancing product processing quality.

[0004] In this prior art, when the furnace body is wide, the length of the radiant tube will be very long, which will cause the radiant tube to bend after long-term use, thereby reducing the overall strength of the product. Utility Model Content

[0005] To address the problem in existing technologies where a wide furnace body results in excessively long radiant tubes that bend over time, reducing overall product strength, this invention provides a wide-body gas-fired heating furnace.

[0013] The advantages of this wide-body gas-fired heating furnace compared with the prior art are as follows: 1. By aligning the third radiant tube with the first radiant tube and the fourth radiant tube with the second radiant tube, the third radiant tube cooperates with the first radiant tube, and the fourth radiant tube cooperates with the second radiant tube to cover the upper area of ​​the drive roller assembly. Compared to covering the upper area of ​​the drive roller assembly with a single radiant tube, this avoids the phenomenon of the radiant tube becoming too long and bending due to the excessive width of the furnace body, thus improving the overall strength of the product. By making the length of the first radiant tube shorter than the length of the second radiant tube and the length of the third radiant tube longer than the length of the fourth radiant tube, the first, second, third, and fourth radiant tubes are staggered, thereby reducing the heating blind spots in the furnace body and improving the uniformity of product heating.

[0014] 2. By installing two first burners on the outside of two first air valves respectively, connecting the output end of the first burners to the first air valves, and connecting the first gas pipe to the two first burners, the gas in the first gas pipe can flow into the first burners, thereby mixing the gas with the air flowing into the first air valves. At the same time, the first burners ignite the gas to generate heat, which flows into the first and second radiant tubes, thereby enabling the first and second radiant tubes to dissipate heat to heat the workpiece.

[0015] 3. By installing two second burners on the outside of two second air valves respectively, connecting the output end of the second burners to the second air valves, and connecting the second gas pipe to the two second burners, the gas in the second gas pipe can flow into the second burners, thereby mixing the gas with the air flowing into the second air valves. At the same time, the second burners ignite the gas to generate heat, which flows into the third and fourth radiant tubes, thereby enabling the third and fourth radiant tubes to dissipate heat to heat the workpiece.

[0016] 4. By installing the fifth radiant tube on one inner wall of the furnace body and the sixth radiant tube on the other inner wall of the furnace body, and positioning the fifth and sixth radiant tubes below the drive roller assembly, heat can flow into the fifth and sixth radiant tubes, thereby enabling the fifth and sixth radiant tubes to dissipate heat and heat the workpiece from below, thus achieving multi-directional heating of the workpiece and improving the heating efficiency of the workpiece.

[0017] 5. By installing the third burner outside the third air valve, connecting the output end of the third burner to the third air valve, and connecting the third burner to the first gas pipe, gas from the first gas pipe can flow into the third burner, thus mixing the gas with the air flowing into the third air valve. Simultaneously, the third burner ignites the gas to generate heat, which flows into the fifth radiant tube, allowing the fifth radiant tube to dissipate heat to heat the workpiece. Similarly, by installing the fourth burner outside the fourth air valve, connecting the output end of the fourth burner to the fourth air valve, and connecting the fourth burner to the second gas pipe, gas from the second gas pipe can flow into the fourth burner, thus mixing the gas with the air flowing into the fourth air valve. Simultaneously, the fourth burner ignites the gas to generate heat, which flows into the sixth radiant tube, allowing the sixth radiant tube to dissipate heat to heat the workpiece.

[0018] 6. By connecting multiple first helical gears to multiple transmission roller assemblies respectively, and mounting multiple second helical gears on the outside of the drive shaft and meshing the second helical gears with the first helical gears, the drive shaft can drive the multiple second helical gears to rotate, thereby enabling the second helical gears to drive the first helical gears to rotate, and thus providing power for rotating the transmission roller assembly.

[0019] 7.

[0020] 8. By installing the corridor panel on top of the furnace body and positioning it above the first air pipe, the furnace body supports the corridor panel, allowing workers to walk on it for maintenance of the furnace top. By installing a guardrail on the end of the corridor panel away from the furnace body, the guardrail protects workers on the corridor panel, thereby improving product safety.

Detailed Implementation

[0022] The following are specific implementation cases and appendices. Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0023] A wide-body gas-fired heating furnace, such as Figures 1 to 6 As shown, the wide-body gas-fired heating furnace includes: a furnace body 10, a drive roller assembly 11, a first radiant tube 12, a second radiant tube 13, a third radiant tube 14, and a fourth radiant tube 15; the furnace body 10 is a hollow cavity; multiple drive roller assemblies 11 are located inside the furnace body 10, and both ends of the multiple drive roller assemblies 11 are rotatably connected to the two inner walls of the furnace body 10 respectively; the first radiant tube 12 is a hollow cavity with an opening at one end, the first radiant tube 12 is installed on one inner wall of the furnace body 10, and the first radiant tube 12 is located above the drive roller assembly 11; the second radiant tube 13 is a hollow cavity with an opening at one end, the second radiant tube 13 is installed on one inner wall of the furnace body 10, and the first radiant tube 12 is located above the drive roller assembly 11. The first radiation tube 12 is located on one side of the second radiation tube 13; the third radiation tube 14 is a hollow cavity with an opening at one end, and is installed on the other inner wall of the furnace body 10. The third radiation tube 14 is located above the transmission roller assembly 11 and is opposite to the first radiation tube 12; the fourth radiation tube 15 is a hollow cavity with an opening at one end, and is installed on the other inner wall of the furnace body 10. The fourth radiation tube 15 is located above the transmission roller assembly 11 and is opposite to the second radiation tube 13; wherein, the length of the first radiation tube 12 is less than the length of the second radiation tube 13, and the length of the third radiation tube 14 is greater than the length of the fourth radiation tube 15.

[0024] By placing multiple drive roller assemblies 11 inside the furnace body 10 and rotatably connecting their two ends to the two inner walls of the furnace body 10, the furnace body 10 supports the multiple drive roller assemblies 11, allowing the drive roller assemblies 11 to rotate within the furnace body 10. This enables the rotating drive roller assemblies 11 to move the workpiece within the furnace body 10 when it is placed on them. By installing a first radiant tube 12 on an inner wall of the furnace body 10 and positioning it above the drive roller assemblies 11, heat can be injected into the first radiant tube 12 for heat dissipation, thus heating the workpiece placed on the drive roller assemblies 11. Similarly, by installing a second radiant tube 13 on an inner wall of the furnace body 10 and positioning it above the drive roller assemblies 11, heat can be injected into the second radiant tube 13 for heat dissipation, thus heating the workpiece placed on the drive roller assemblies 11. By installing the third radiant tube 14 on an inner wall of the furnace body 10 and positioning it above the drive roller assembly 11, heat can be injected into the third radiant tube 14, thereby dissipating heat through the third radiant tube 14 to heat the workpiece placed on the drive roller assembly 11. By installing the fourth radiant tube 15 on an inner wall of the furnace body 10 and positioning it above the drive roller assembly 11, heat can be injected into the fourth radiant tube 15, thereby dissipating heat through the fourth radiant tube 15 to heat the workpiece placed on the drive roller assembly 11. By positioning the third radiant tube 14 opposite the first radiant tube 12 and the fourth radiant tube 15 opposite the second radiant tube 13, the third radiant tube 14 cooperates with the first radiant tube 12, and the fourth radiant tube 15 and the second radiant tube 13 cooperate to cover the upper area of ​​the transmission roller assembly 11. This allows the first radiant tube 12, the second radiant tube 13, the third radiant tube 14, and the fourth radiant tube 15 to cooperate in heating the workpiece placed on the transmission roller assembly 11, thereby improving the heating efficiency of the workpiece.

[0025] By employing the above structure, the third radiant tube 14 is positioned opposite the first radiant tube 12, and the fourth radiant tube 15 is positioned opposite the second radiant tube 13. This allows the third radiant tube 14 to cooperate with the first radiant tube 12, and the fourth radiant tube 15 and the second radiant tube 13 to cooperate in covering the upper area of ​​the drive roller assembly 11. Compared to covering the upper area of ​​the drive roller assembly 11 with a single radiant tube, this avoids the phenomenon of excessively long radiant tubes due to the excessive width of the furnace body 10, which could cause the radiant tubes to bend, thus improving the overall strength of the product. By making the length of the first radiant tube 12 shorter than the length of the second radiant tube 13, and the length of the third radiant tube 14 longer than the length of the fourth radiant tube 15, the first radiant tube 12, the second radiant tube 13, the third radiant tube 14, and the fourth radiant tube 15 are staggered, thereby reducing the heating blind spots within the furnace body 10 and improving the uniformity of product heating.
