Specifically, the distance between each vent hole 24 and the axis of the trapezoidal tower 21 is smaller than the distance between the slag leaking hole 23 adjacent to the vent hole and the axis of the trapezoidal tower 21.

In the embodiment, under the action of the centrifugal force of the rotation of the slag removing chassis 2, slag leaks into the lower grate 22 from the edge of the upper grate 22 or the slag leaking holes 23, and because the vent holes 24 are distributed between the two adjacent grates 22 and the distance between the vent holes 24 and the axial lead of the trapezoidal tower 21 is smaller than the distance between the adjacent slag leaking holes 23 and the axial lead of the trapezoidal tower 21, the grate 22 arranged above the vent holes 24 is equivalent to a baffle plate for blocking the slag at this time, so that the slag leaking from the slag leaking holes 23 cannot directly enter the vent holes 24, thereby effectively avoiding the blockage of the vent holes 24 and being beneficial to the uniform gas distribution of the grate structure 5.

Further, a plurality of small ash knives 25 are distributed on the outer wall of the base 19.

In the present embodiment, the small-sized blades 25 guide the slag to be discharged from the slag discharge gap 9 out of the furnace body 1, thereby further increasing the slag discharge effect.

As shown in fig. 6 and 7, the slag discharging mechanism 10 further includes a large ash knife 26, the large ash knife 26 is composed of a baffle plate 27 and an arc discharge chute 28 connected to the end of the baffle plate 27 and having smooth transition, the baffle plate 27 is obliquely inserted into the tub body 3, a discharge port of the arc discharge chute 28 extends out of the edge of the tub body 3, when the tub body 3 rotates, slag in the tub body 3 moves to the arc discharge chute 28 through the baffle plate 27 and is discharged from the discharge port of the arc discharge chute, and an adjusting mechanism 29 for adjusting a pitch angle of the large ash knife 26 is further connected to the large ash knife 26.

In this embodiment, the output shaft of the adjustment motor 31 rotates to drive the first chain wheel 32 to rotate, so that the first chain wheel 32 drives the second chain wheel 33 to rotate, and the large ash knife 26 rotates along with the second chain wheel 33 because the large ash knife is connected with the second chain wheel 33 through the transmission shaft 35. Therefore, the pitch angle of the large ash knife 26 can be adjusted by controlling the angular displacement of the rotation of the adjusting motor 31. As the slag rotates along with the chassis, when the slag reaches the striker plate 27, the slag moves to the arc-shaped discharge chute 28 through the striker plate 27 and is discharged outwards from the discharge hole of the arc-shaped discharge chute; in addition, when the slag is relatively tight, the driving motor 15 is controlled to rotate forwards or reversely continuously, so that the material baffle plate 27 is continuously shoveled into the slag, and when the large ash knife 26 rotates, the slag shoveled by the material baffle plate 27 slides into the arc-shaped discharge chute 28 along with the material baffle plate 27 and is discharged from the arc-shaped discharge chute 28; meanwhile, the striker plate 27 continuously shovels the slag to loosen the slag in the pot body 3.
