[0022] See also Figure 1 and Figure 4 The supporting mechanism 7 includes a supporting box 17, and there are two supporting boxes 17. The supporting boxes 17 are fixedly installed at the bottom of the installation body 1. The top of the inner cavity of the supporting box 17 is fixedly connected to a hydraulic cylinder 18. The output end of the hydraulic cylinder 18 passes through the outside of the supporting box 17 and is fixedly connected to a supporting plate 19.

[0024] See also Figure 1 and Figure 3 The splicing mechanism 22 includes a connecting block 11, and the number of the connecting blocks 11 is four. The top waste heat recovery plate 8 is fixedly installed at the bottom of the top waste heat recovery plate 8. The top of the bottom waste heat recovery plate 2 is fixedly connected with a connecting frame 12. The two connecting frames 12 are penetrated by positioning pins 13 on the opposite sides of the front and rear. The two positioning pins 13 are fixedly connected to the pulling plate 14 on the opposite sides.
