A plurality of fan blades 9 are fixedly connected to the transmission shaft 8. The transmission shaft 8 is arranged above the combustion table 20. Gears 10 are fixedly connected to both ends of the transmission shaft 8 and the output end of the transmission motor 2. The gear 10 is connected to the transmission crawler 3 through sawtooth meshing, and the sawtooth is fixedly connected to the inner side of the transmission crawler 3. A top plate 11 is fixedly connected to the upper surface of the combustion chamber 1. Two groups of exhaust components are symmetrically fixedly connected on the top plate 11. The exhaust component includes three exhaust pipes 12. The three exhaust pipes 12 are closely attached and reciprocatingly folded in a zigzag shape. The top plate 11 on the upper surface of the combustion chamber 1 is connected by setting the exhaust pipe 12, and a ventilation grid 4 and a negative pressure fan 6 are arranged at the bottom of the side of the combustion chamber 1. The exhaust gas and heat after combustion are transported through the exhaust pipe 12 by using the air pressure difference, and the exhaust pipe 12 is folded and placed in the curing and baking chamber, which can better retain the heat of combustion under the premise of exhausting exhaust gas pollution.

[0024] A curing and baking chamber 13 is fixedly connected to the upper surface of the top plate 11, and two slide rails 17 are symmetrically fixedly connected to the inner top surface of the curing and baking chamber 13.

The natural gas can be released in a more refined manner through the natural gas release terminal 19, so that it can be burned more fully. Through the action of the transmission motor 2 and the transmission crawler 3, the rotation of the transmission shaft 8 is driven, and finally the fan blades 9 are driven to discharge the heat and exhaust gas after combustion through the exhaust pipe 12. The exhaust gas and heat after combustion are transported through the exhaust pipe 12 by utilizing the air pressure difference, and the exhaust pipe 12 is folded and placed in the curing and baking chamber. Under the premise of discharging exhaust gas pollution, the heat of combustion can be better retained. The temperature in the curing and baking chamber 1 can be better known by the temperature detection needle 18 and the outer side display screen 16 arranged in the curing and baking chamber 1. For this reason, the temperature change caused by heat can be more accurately controlled, thereby improving a better output rate. After meeting the required temperature, the object to be cured is hung under the slide rail 17, and the surface powder can be cured by waiting for the heat to cure.
