When the temperature is too high, it is cooled by the first water-cooling jacket 5 and the second water-cooling jacket 13 arranged on the outside of the chute 14 and the shell 1, so as to protect the chute 14 and the shell 1. When the liquid temperature inside the first water-cooling jacket 5 and the second water-cooling jacket 13 is too high, the heat inside the first water-cooling jacket 5 and the second water-cooling jacket 13 is recovered through the heat exchanger 7, and then the heat is transported to the interior of the combustion chamber 2 through the blower 6, so as to reduce the fuel consumption and reduce the drying cost.

When the equipment needs to be moved, the height between the first telescopic block 16 and the second telescopic block 17 can be adjusted by pressing the limit rod 19 and slidingly connecting with different connecting ports 18. The height between the first telescopic block 16 and the second telescopic block 17 can be adjusted at the same time.
