Inside the lower side of the air box 4, a dust collection box 8 is slidably connected, and the dust collection box 8 is used to collect the dust blocked by the filter plate 6. On the right sides of the filter plate 6 and the dust collection box 8, handles 9 are fixedly connected, and the handles 9 are used to pull the filter plate 6 and the dust collection box 8 out of the air box 4. On the rear side of the air box 4, an air inlet pipe 7 is fixedly connected, and the air inlet pipe 7 is used to absorb waste heat gas. The lower part of the air inlet pipe 7 is fixedly connected to the upper rear side of the air box 4. On the upper part of the kiln bottom 1, a track 11 is arranged, and the track 11 is used to guide the movement trajectory of the conveying equipment inside the kiln. Inside the rear side of the air box 4, a chamber 16 is opened, and the chamber 16 is used to process waste heat gas. The filter plate 6 and the dust collection box 8 both slide inside the chamber 16. The input end of the fan 12 is fixedly connected to the front side inside the chamber 16, and the input end of the fan 12 can absorb and transport waste heat gas. On the lower part of the filter plate 6, a chute 13 is opened, and the lower side inside the air box 4 slides inside the chute 13.

Mullite bricks have excellent high temperature resistance and can withstand the high temperature environment in the kiln without deformation or damage. As an internal insulation layer, it directly faces the high temperature in the kiln, providing the first barrier for the entire kiln wall structure, and preventing high temperature from eroding the external insulation layer and the main body of the kiln wall.

[0033] Working principle: During the process of firing the foamed ceramic plate in the tunnel kiln, a large amount of waste heat gas is generated at the rear. The fan 12 is started to absorb the waste heat gas into the air inlet pipe 7 through its input end. The air inlet pipe 7 can transport the waste heat gas to the chamber 16 inside the bellows 4. The filter plate 6 can filter the dust in the waste heat gas to prevent the dust from entering the inside of the fan 12 and damaging it. The filtered dust will fall into the dust box 8 below. The lever 5 is moved to squeeze the spring 15 so that the lower part of the lever 5 can be disengaged from the inside of the slot 14, thereby releasing the fixation of the filter plate 6. The filter plate 6 can be pulled by pulling the handle 9. The filter plate 6 and the dust box 8 are pulled out for cleaning. The insulation layer 18 of the tunnel kiln made of aluminum silicate fiber felt can prevent the heat in the kiln from being lost to the outside of the kiln, improve the insulation performance of the tunnel kiln, and reduce energy consumption. The aluminum silicate fiber felt material can adapt to a certain degree of temperature changes and will not crack due to thermal expansion and contraction, thereby ensuring long-term and stable insulation effect. The insulation layer 19 of the tunnel kiln made of mullite brick material can withstand the high temperature environment in the kiln without deformation or damage. The mullite brick material has good thermal stability and small volume change at high temperature, which can ensure the stability of the temperature in the kiln and create good conditions for the firing of foamed ceramic panels.
