[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0023] Example:

[0024] like Figures 1 to 3 As shown, a dual-channel high-pressure hot air mechanism includes: a high-pressure pipe body 1, the high-pressure pipe body 1 is provided with an air inlet 102 and an air outlet 103, the air inlet 102 is fixedly connected with an 18.5KW high-pressure fan, compared with the traditional mechanism, the 18.5KW high-pressure fan is used directly as the combustion-supporting air, which can save the relevant cost of an air compressor, and the high-pressure fan drives the air to move from the air inlet 102 to the air outlet 103, and a combustion-supporting pipe body 2 is arranged in the high-pressure pipe body 1.

[0025] The combustion-supporting tube body 2 extends from the air inlet 102 of the high-pressure tube to the air outlet 103 of the high-pressure tube body 1. The combustion-supporting tube body 2 is located at the air inlet 102 of the high-pressure tube body 1 and is provided with a damper 3. When the high-pressure fan drives the air to move from the air inlet 102 to the air outlet 103, a part of the air will be brought into the combustion-supporting tube body 2, and the air volume entering the combustion-supporting tube body 2 is controlled by the damper 3.

[0026] The damper 3 includes: a manual damper and an electric damper. The manual damper is close to the air inlet 102. The dampers 3 include: a baffle 301 fixedly arranged in the combustion-supporting tube body 2, each baffle 301 is provided with two air inlet holes, the high-pressure tube body 1 is equipped with an operating rod 302, the operating rod 302 is provided with two exhaust holes matched with the air inlet holes, and the high-pressure tube body 1 is fixed with a servo motor, which drives the operating rod of the electric damper to rotate, thereby driving the exhaust holes to communicate with the air inlet holes.

[0027] The servo motor drives the operating rod 302 to rotate, thereby driving the exhaust hole on the operating rod 302 to connect with the air inlet hole of the partition 301, thereby adjusting the air volume in the combustion-supporting tube body 2. The servo motor can automatically control the power size, and there is no need to adjust the air pressure on the mechanism when adjusting the power like the traditional method, which saves the operator a lot of trouble.

[0028] A gas pipeline 8 is provided at the middle end of the high-pressure tube body 1. The gas pipeline 8 passes through the high-pressure tube body 1 and the combustion-supporting tube body 2 and extends into the combustion-supporting tube body 2. The high-pressure tube body 1 is fixedly connected to an ignition component 7. The ignition component 7 uses an ignition transformer to drive the electrode to discharge so that the ignition is finally successful.

[0029] The ignition assembly 7 extends into the combustion-supporting tube body 2 and cooperates with the gas pipeline 8 to drive the gas ignition. The air in the high-pressure tube body 1 is mixed with the air in the combustion-supporting tube body 2 and discharged from the air outlet 103. The gas pipeline 8 extends to the combustion-supporting pipeline and is provided with an ignition shell 6. The ignition shell 6 is arranged in a trumpet shape. The trumpet-shaped ignition shell 6 can increase the contact area between the air and the gas and improve the ignition effect.

[0030] The gas pipeline 8 is fixedly connected with a linear flow regulating valve, the temperature can be accurately controlled, and through the double-stage damper setting, the high-pressure fan can be operated at a high frequency without affecting the temperature.

[0031] The high-pressure pipe body 1 and the combustion-supporting pipe body 2 are both provided with a fire-viewing hole 4. The high-pressure pipe body 1 is fixedly connected with a flame detection installation 5, which extends into the combustion-supporting pipe body 2. The fire-viewing hole 4 and the flame detection installation 5 cooperate to observe the ignition condition in the combustion-supporting pipe body 2.

[0032] like Figures 1 to 3 As shown, when working, the high-pressure fan drives the air to move from the air inlet 102 to the air outlet 103. At this time, part of the air blown out by the high-pressure fan moves along the high-pressure tube body 1, and the other part enters the combustion-supporting tube body 2 and moves toward the air outlet 103 of the high-pressure tube body 1. At this time, the air volume entering the combustion-supporting tube body 2 is controlled by the damper 3, so as to facilitate the ignition component 7 to cooperate with the fuel gas and air to achieve ignition, drive the air in the combustion-supporting tube body 2 to heat up, and be discharged from the air outlet 103 of the high-pressure tube body 1 after mixing with the air.

[0033] When the ignition assembly 7 is ignited, the ignition status can be observed in real time through the cooperation of the fire viewing hole 4 and the flame detection installation location 5, and the air door 3 can be adjusted to control the air volume.

[0034] Therefore, various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
