On the top of the conveying fan 16, a heating seat 14 is installed. On one side of the conveying fan 16, a conveying pipe 5 is installed. At the bottom of the conveying pipe 5, an air inlet pipe 4 is connected. On one side of the heating seat 14, it is connected to the furnace body 3. On one side of the furnace body 3, a discharge seat opening 17 is installed. On the top of the discharge seat opening 17, an air suction port 15 is installed;

[0024] The air inlet pipes 4 are inserted into the top of the furnace body 3 at equal intervals. The furnace body 3 is communicated with the conveying pipe 5 through the air inlet pipes 4. The conveying fan 16 is fixed on the top of the furnace body 3 through the fixed frame 22. The air suction port 15 is communicated with the conveying pipe 5 through the heating seat 14 and the conveying fan 16. The discharge seat opening 17 is fixed on one side of the furnace body 3;

[0025] Specifically, as Figure 1 and Figure 2 shown, by setting up a hot air circulation structure, when in use, the conveying fan 16 fixed on the fixed frame 22 at the top of the furnace body 3 is started. Then, the air inside the furnace body 3 is conveyed to the inside of the heating seat 14 on one side of the air suction port 17 through the discharge seat opening 17. After being heated and insulated by the heating seat 14, it is conveyed to the conveying pipe 5 through the conveying fan 16 and then conveyed back to the inside of the furnace body 3 through the air inlet pipes 4 at the bottom of the conveying pipe 5, so that the air inside the furnace body 3 circulates to keep the temperature inside the furnace body 3 uniform, thus realizing the hot air circulation function.

[0026] Embodiment 2: A buffer spring 19 is installed at the bottom of the furnace body 3. At the bottom of the buffer spring 19, an adjusting threaded rod 11 is connected. An adjusting brush seat 12 is connected to the outside of the adjusting threaded rod 11. A fixing nut 21 is sleeved on the outside of the adjusting brush seat 12. A cleaning brush body 20 is installed at the bottom of the adjusting brush seat 12;

[0027] The adjusting threaded rod 11 is inserted into the front and rear ends of the adjusting brush seat 12. The fixing nut 21 is sleeved on the outside of the adjusting threaded rod 11 to fix the adjusting brush seat 12 on the outside of the adjusting threaded rod 11. The adjusting brush seat 12 drives the cleaning brush body 20 to contact the metal mesh belt 7 at the bottom of the furnace body 3. The adjusting threaded rod 11 can telescopically move with the furnace body 3 through the buffer spring 19;

[0028] Specifically, as Figure 1 and Figure 3As shown, by setting up a mesh belt cleaning structure, when the rotating motor 10 drives the idling machine 9 to drive the metal mesh belt 7 outside the driving roller 8 to move, it drives the metal mesh belt 7 inside the furnace body 3 to move among the conveying rollers 1 and the rollers inside the furnace body 3. When the metal mesh belt 7 moves to the bottom of the furnace body 3, it contacts the bottom of the cleaning brush body 20 of the adjusting brush base 12 connected to the idling machine 9 and the adjusting screw rod 11 at the bottom of the furnace body 3. Through the friction between the cleaning brush body 20 and the moving metal mesh belt 7, the mesh belt cleaning function is realized.

[0029] Embodiment 3: An adsorption layer 23 is installed at the inner top of the discharge seat opening 17. A filter cotton 24 is arranged at the bottom of the adsorption layer 23. A filter net 25 is arranged at the bottom of the filter cotton 24. Sliding doors 26 are inserted into the front and rear ends of the discharge seat opening 17. A discharge port 28 is arranged on one side of the discharge seat opening 17. A sliding groove 27 is arranged at the top of the discharge port 28.

[0030] The adsorption layer 23, the filter cotton 24 and the filter net 25 are sequentially fixed inside the discharge seat opening 17. After the sliding door 26 is inserted into the front end of the discharge seat opening 17, it slides in the sliding groove 27 above the discharge port 28 on one side of the discharge seat opening 17. The discharge port 28 is communicated with the furnace body 3 through the discharge seat opening 17.

[0031] Specifically, as Figure 1 and Figure 4 shown, by setting up an air outlet filtering structure, when in use, the air inside the furnace body 3 is conveyed to the air suction port 15 through the discharge seat opening 17. The sliding doors 26 at the front and rear ends of the discharge seat opening 17 slide in the sliding groove 27 above the discharge port 28 on one side of the discharge seat opening 17 to adjust the outlet of the discharge port 28, so that the air inside the furnace body 3 is filtered through the filter net 25, the filter cotton 24 and the adsorption layer 23 inside the top of the discharge seat opening 17, reducing the impurities in the air for circulation, and thus the air outlet filtering function is realized.

[0032] Working principle: In the utility model, the sliding doors 26 at the front and rear ends of the discharge seat opening 17 slide in the sliding groove 27 above the discharge opening 28 on one side of the discharge seat opening 17 to adjust the outlet of the discharge opening 28. After starting the conveying fan 16 fixed on the fixed frame 22 at the top of the furnace body 3, the air inside the furnace body 3 is conveyed through the discharge seat opening 17 into the heating seat 14 on the side of the air suction opening 15. After being heated and insulated by the heating seat 14, it is conveyed by the conveying fan 16 to the conveying pipe 5 and then back into the furnace body 3 through the intake pipe 4 at the bottom of the conveying pipe 5. The air inside the furnace body 3 passes through the filter screen 25, filter cotton 24 and adsorption layer 23 inside the top of the discharge seat opening 17 for filtration, reducing the circulation of air impurities inside the furnace body 3. The rotation motor 10 drives the idling machine 9 to drive the movement of the metal mesh belt 7 outside the driving roller 8, driving the metal mesh belt 7 inside the furnace body 3 to move among the conveying rollers 1 and the rollers inside the furnace body 3. When the metal mesh belt 7 moves to the bottom of the furnace body 3, it reaches the bottom of the cleaning brush body 20 of the adjusting brush seat 12 connected to the idling machine 9 and the adjusting threaded rod 11 at the bottom of the furnace body 3. Through the friction between the cleaning brush body 20 and the moving metal mesh belt 7, the adjusting threaded rod 11 drives the adjusting brush seat 12 to drive the cleaning brush body 20 at the bottom to expand and contract to clean the metal mesh belt 7.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
