[0044] Working principle: When the present invention is used, it includes the following steps:

[0045] Step 1: First, add the raw materials into the box body 1 through the feed hopper. After the addition is completed, the feed hopper is sealed, and the hot gas output source is connected to the air inlet chamber 206 through the pipeline. Then, the first purification plate 404, the second purification plate 405 and the third purification plate 406 are inserted from the upper end of the connecting pipe 403 in sequence, so that the first purification plate 404 is on the fixed grid plate 402, and then the operating blocks are rotated respectively to rotate the two external threaded rods 408, and the two external threaded rods 408 rotate to make the two pressing blocks 407 move toward each other, and the two pressing blocks 407 move toward each other to press the first purification plate 404, the second purification plate 405 and the third purification plate 406;

[0046] Step 2: Start the driving motor 203 and the heating plate. The driving motor 203 rotates to rotate the driving gear 205. The driving gear 205 rotates through the tooth block meshing to rotate the driven gear 204. The driven gear 204 rotates to rotate the rotating shaft 201. The rotating shaft 201 rotates to rotate the serpentine stirring tube 208. The serpentine stirring tube 208 rotates to mix and stir the raw materials inside the box 1. The hot air passes through the air inlet cavity 206, the serpentine stirring tube 208 and the air outlet cavity 207 in sequence, and then is discharged from the connecting pipe 403, so that the raw materials inside the box 1 are heated more evenly.

[0047] Step 3: The air pressure inside the box 1 is continuously increased by the cooperation between the heating plate and the serpentine stirring tube 208, and then the sealing plate 304 moves upward through the air outlet and the air inlet, and the upward movement of the sealing plate 304 causes the movable rod 305 to move, and the movement of the movable rod 305 causes the top plate 303 to move upward, and the upward movement of the top plate 303 drives the annular protective cylinder 302 and the rotating cylinder 310 to move upward, and the upward movement of the rotating cylinder 310 drives the connecting tube 403 to move upward, and the upward movement of the connecting tube 403 drives the piston 317 to move upward, and the upward movement of the piston 317 causes the air inlet chamber 206, the serpentine stirring tube 208 and the air outlet chamber to move upward. The hot gas flow velocity in 207 is accelerated, and the rotating cylinder 310 moves upward to drive the sleeve 311 to move upward. The sleeve 311 moves upward and gradually contacts the ball 314 at the lower end of the convex strip 313. When the plug-in groove in the middle of the sleeve 311 is not aligned with the convex strip 313, the compression spring 312 is compressed, and the rotation of the rotating shaft 201 drives the convex strip 313 to rotate. The rotation of the convex strip 313 causes the ball 314 to roll on the upper end surface of the sleeve 311. When the rotating shaft 201 rotates to align the convex strip 313 with the plug-in groove, the sleeve 311 moves upward under the action of the compression spring 312 being reset, and then the convex strip 313 is inserted into the plug-in groove.

[0048] Step 4: The rotation of the rotating shaft 201 drives the sleeve 311 to rotate, and the rotation of the sleeve 311 drives the rotating cylinder 310 to rotate. The rotation of the rotating cylinder 310 causes the first gear 315 to rotate, and the first gear 315 rotates through the tooth block meshing to cause the two transmission gears 309 to rotate, and the two transmission gears 309 rotate through the transmission shaft 308 to cause the fan 307 to rotate, and the fan 307 rotates to discharge the gas inside the annular protective cylinder 302 into the purification component 4, and at the same time, the annular protective cylinder 302 can be supplemented with gas through the one-way valve, and then when the sealing plate 304 moves upward to make the exhaust port 316 communicate with the inside of the box body 1, the annular protective cylinder 302 moves upward to drive the limit ring to move upward, and the limit ring squeezes the touch button of the alarm 318 so that the alarm 318 sounds an alarm, which promptly reminds the staff, and then the gas inside the box body 1 is discharged into the annular protective cylinder 302 through the exhaust port 316, and the gas is purified under the action of the fan 307;

[0049] Step 5: The rotating cylinder 310 rotates to drive the fixed grid plate 402 to rotate through the connecting tube 403, and the fixed grid plate 402 rotates to rotate the installation cylinder 401, and the installation cylinder 401 rotates to drive the first purification plate 404, the second purification plate 405 and the third purification plate 406 to rotate, so that the relative positions of the first purification plate 404, the second purification plate 405 and the third purification plate 406 and the fan 307 are changed, so as to prevent the gas discharged by the fan 307 from being purified and filtered at the same position of the first purification plate 404, the second purification plate 405 and the third purification plate 406, thereby affecting the purification and filtering effect;

[0050] Step six: When the gas inside the box body 1 is discharged, the air pressure inside the box body 1 drops, and then the sealing plate 304 moves downward under the action of the telescopic spring 306, so that the opening of the exhaust port 316 is reduced or closed, and the sealing plate 304 moves the top plate 303 downward through the movable rod 305. The downward movement of the top plate 303 causes the annular protective tube 302 and the limit ring to move downward, releasing the squeeze on the touch button of the alarm 318, so that the alarm 318 stops sounding the alarm.
