[0024] By setting two heat preservation shells 2, and rotatingly connecting them on both sides of the heat preservation supporting plate 11, when the split cylinder 7 needs to be detected and maintained, the two heat preservation shells 2 can be rotated to be away from the split cylinder 7, so that the split cylinder 7 can be maintained, and after the maintenance is completed, the two heat preservation shells 2 are rotated to be combined and wrapped outside the split cylinder 7, avoiding the time waste and cost increase caused by the need to redo the heat preservation layer after each maintenance; by filling the heat preservation particle filler 8 in the gap between the heat preservation shell 2 and the split cylinder 7, the heat preservation effect is further improved, and the heat loss is reduced, and the heat preservation particle filler 8 can be reused.

[0025] In order to facilitate the filling of the heat preservation particle filler 8, the top end of the heat preservation shell 2 is connected with the filler pipe 3, and the top end of the filler pipe 3 is provided with the sealing cover 4.
