[0024] Embodiment 2:

[0025] A filtering component 6 is arranged outside the sponge board 5. The filtering component 6 includes a pressing plate 61 which is made of a material with compressive resistance, high temperature and corrosion resistance. The outer surface of the pressing plate 61 is fixedly connected with the outer surface of the sponge board 5 and the inside of the inner cavity 3 respectively. A filter screen 62 is arranged below the pressing plate 61. The filter screen 62 is made of a material with compressive resistance and wear resistance. The dehydration of the sponge board 5 is facilitated through the filter holes. The outer surface of the filter screen 62 is fixedly connected with the outer surface of the sponge board 5. The outer surface of the filter screen 62 is movably connected with the inside of the inner cavity 3 and the outer surface of the cutting roller 1 respectively. A top plate 63 is movably connected to the outer surface of the filter screen 62. The top plate 63 is made of a material with compressive resistance and wear resistance, and chamfers are arranged on both sides to reduce the contact wear. A filter plate 64 is movably connected to the outer surface of the top plate 63. The filter holes of the filter plate 64 can filter the combustion ashes to realize the recycling of liquid water.
