[0029] It should be noted that the water outlet 21 and the water inlet 22 both penetrate the furnace shell 1 , and both the water outlet 21 and the water inlet 22 extend to the outside of the furnace shell 1 .

[0030] By adopting the above technical solution, cooling water enters the cooling wall 2 through the water inlet 22, and the heat in the furnace shell 1 is cooled by the cooling water, so that the heat transferred from the furnace shell 1 is smoothly discharged, and finally the cooled cooling water is discharged through the water outlet 21.

[0031] In this embodiment, as the preferred technical solution of the utility model, the reinforcement mechanism 4 includes a reinforcement rod 41, which is movably arranged in the furnace shell 1. After the positioning block 3 is assembled in the furnace shell 1, the positioning block 3 is fixed to the furnace shell 1 through the reinforcement rod 41.

[0032] By adopting the above technical solution, after the cooling wall 2 is assembled in the furnace shell 1 through the positioning block 3, the positioning block 3 can be fixed by inserting the end of the reinforcement rod 41 into the positioning block 3, so that the cooling wall 2 is reinforced in the furnace shell 1, the cooling wall 2 is firmly connected, and the firmness of the cooling wall 2 can be improved.

[0033] In this embodiment, as a preferred technical solution of the utility model, the reinforcement rod 41 is arranged on the linkage plate 42, and the linkage plate 42 is threadedly connected to the transmission screw 43.
