[0054] Working principle:

[0055] Step 1: The mineral raw materials are transported to the machine body 1 through the conveyor belt 10 for firing.

[0056] Step 2: During the firing process, the smoke treatment device extracts the smoke generated in the machine body 1 through the smoke exhaust pipe 4 to the smoke treatment device for harmless treatment. When the smoke in the machine body 1 is extracted through the smoke exhaust pipe 4, the negative pressure thrust generated by the smoke lifts the flap 803 upward through the fixed shaft 802 to form a one-way channel. At the same time, the negative pressure in the smoke exhaust pipe 4 sucks out the gas in the siphon pipe 501, so that the siphon pipe 501 also forms a negative pressure, thereby sucking the smoke escaping from the vicinity of the feed port through the collection bucket 502 and into the smoke exhaust pipe 4 through the siphon pipe 501;

[0057] Step 3: While extracting the smoke, start the motor 602, which drives the fan shaft 901 to rotate through gear transmission, thereby driving the fan blades 902 to rotate, so that upward wind is generated in the fan shell 2, and auxiliary wind force is generated at the bottom of the smoke exhaust pipe 4, which assists the body 1 to generate smoke that enters the smoke exhaust pipe 4, avoiding large smoke accumulation in the body 1.
