A fan 32 is fixedly connected to the top side of the air supply cylinder 31. A connecting pipe 33 is fixedly connected to the other end of the fan 32. A drying chamber 35 is fixedly connected to one end of the connecting pipe 33. A three-way pipe 38 is fixedly connected to the other end of the three-way pipe 38. Air inlets 39 are fixedly connected to both ends of the three-way pipe 38. The other ends of the two air inlets 39 are fixedly connected to the other side of the furnace body 1. A connecting frame 37 is installed inside the drying chamber 35. A drying layer 36 is fixedly connected to the inner side of the connecting frame 37. Multiple filter holes are opened at one end of the connecting frame 37, and an opening is opened at the other end of the connecting frame 37. An installation plate 34 is fixedly connected to the other end of the drying chamber 35.
[0025] During operation, the blower 32 drives the gas inside the furnace body 1 to enter the two ends of the three-way pipe 38 through the two air inlets 39. After converging at the other end of the three-way pipe 38, the gas enters the interior of the drying chamber 35. First, the gas enters the interior of the connecting frame 37 through multiple filter holes on one side of the connecting frame 37, and then passes through multiple inclined drying layers 36 in sequence to absorb the water vapor inside the gas. The dried gas enters the interior of the connecting pipe 33 through the opening on the top side of the connecting frame 37, and is driven by the blower 32 to be sent into the interior of the furnace body 1 through the air delivery pipe 31. This dries the gas inside the furnace body 1 and simultaneously realizes the circulation of hot gas, improving the firing effect of hollow bricks.
[0026] Example 2: Figure 1 and Figure 2 As shown, the firing mechanism 2 includes a fixed base plate 26, a rotating disk 23 rotatably connected to the top side of the fixed base plate 26, a second torsion shaft 212 fixedly connected to the bottom side of the rotating disk 23, and a support frame 27 fixedly connected to the top side of the rotating disk 23; a placement plate 28 is fixedly connected to the inner side of the support frame 27, and multiple placement plates 28 are equidistantly distributed; a connecting frame 29 is provided on the outside of the support frame 27, and one end of the connecting frame 29 is fixedly connected to the top side of the rotating disk 23; one end of the second torsion shaft 212... The furnace body 1 is fitted with a first torsion shaft 210. One end of the first torsion shaft 210 is fixedly connected to a connecting shaft 211. One end of the connecting shaft 211 passes through the bottom side of the furnace body 1 and is fixedly connected to a drive motor 24. One side of the drive motor 24 is fixedly connected to the bottom side of the furnace body 1. A sliding strip 25 is fixedly connected to the bottom side of the fixed base plate 26.

A drive assembly 22 is installed on the top wall of the furnace body 1.
[0027] The overall effect of this embodiment is that hollow bricks are placed on multi-layer placement plate 28, the top of connecting frame 29 is threadedly connected to the threaded rod in drive assembly 22, and drive assembly 22 is driven by an external power source to move connecting frame 29. The sliding strip 25 at the bottom of fixed base plate 26 slides outside guide rail 21, which can send the hollow bricks to be fired into the interior of furnace body 1, so that the bottom of second torsion shaft 212 is engaged with the top of first torsion shaft 210. Drive motor 24 works to drive connecting shaft 211 to rotate, which in turn drives first torsion shaft 210, second torsion shaft 212, rotating disk 23 and placement plate 28 to rotate, causing the hollow bricks placed on placement plate 28 to rotate, so as to fire the hollow bricks evenly and improve the firing quality.
[0028] The method of use and working principle of this device: Hollow bricks are placed on multi-layer placement plates 28. The connecting frame 29 moves to send the hollow bricks to be fired into the interior of the furnace body 1 for firing. The bottom end of the second torsion shaft 212 is engaged with the top end of the first torsion shaft 210. The drive motor 24 works to drive the connecting shaft 211 to rotate, which in turn drives the first torsion shaft 210, the second torsion shaft 212, the rotating disk 23 and the placement plate 28 to rotate. This causes the hollow bricks placed on the placement plate 28 to rotate and be fired. The blower 32 works to drive the gas inside the furnace body 1 through the air inlet 39 and the three-way pipe 38 into the interior of the drying chamber 35. The gas passes through multiple inclined drying layers 36 in sequence, absorbing the water vapor inside the gas. The dried gas is then driven by the blower 32 to be sent into the interior of the furnace body 1, realizing the circulation of hot gas inside the furnace body 1.
