Example 2

In order to avoid movement interference, a gap is arranged between the inner ring of the slag supporting plate 71 and the outer wall of the rotary drum 14; in order to ensure the installation, a first connecting plate 72 is fixedly arranged between the slag supporting plate 71 and the bottom of the incinerator 10. Namely: the upper end of the first connecting plate 72 is fixedly connected with the bottom of the incinerator 10, and the lower end of the first connecting plate 72 is fixedly connected with the slag supporting plate 71. The number of the first connecting plates 72 is generally 6-8, the first connecting plates are vertically arranged, slag falling cannot be blocked, the slag supporting plates 71 extend into the annular groove 20 for a certain length, and the falling of the slag needs a certain self-flowing angle, so that the slag is prevented from falling under the condition of no external force.

Example 3

The slag-removing assembly also comprises a second connecting plate 31 for fixedly connecting the slag-removing plate 32 with the outer wall of the rotary drum 14. One end of the second connecting plate 31 is fixedly connected with the upper end of the slag pulling plate 32, and the other end of the second connecting plate 31 is fixedly connected with the outer wall of the rotary drum 14.
