The discharge port end of the cylinder 6 is protected by the plurality of protective plates 7 for 360° omnidirectional heat insulation, which can effectively prevent the discharge port of the cylinder 6 from being damaged due to high temperature. When the protective device 3 is locally damaged, only the damaged protective plate 7 needs to be replaced to achieve maintenance, and the maintenance cost is lower in the later period.

[0026] Further improvement is that the protective plate 7 includes a kiln tail guard 5 and a cooling guard 4, the kiln tail guard 5 is provided with a U-shaped clamping groove 9, the side of the discharge port of the cylinder 6 extends into the U-shaped clamping groove 9, one end of the cooling guard 4 extends into the U-shaped clamping groove 9, and the cooling guard 4, the kiln tail guard 5 and the cylinder 6 are fixed in series by the fasteners 8.

[0027] The protection plate 7 is composed of the kiln tail guard 5 and the cooling guard 4, the kiln tail guard 5 is protected by being sleeved on the edge of the discharge port of the cylinder 6 through the U-shaped clamping groove 9, and the outer side of the discharge port of the cylinder 6 is protected again by the cooling guard 4, heat is guided outward and cooled rapidly through the heat conduction principle, and deformation and damage of the discharge port end of the cylinder 6 and the protection device 3 due to high temperature are avoided.

[0028] Further improvement is that the cooling guard 4 is arranged outside the discharge port of the cylinder 6, and the cooling guard 4 and the outer side of the discharge port of the cylinder 6 form a certain heat dissipation gap 10.

[0029] When the wind blows along the outer side of the cylinder 6 to the protection plate 7, the wind enters the heat dissipation gap 10 to cool and dissipate heat of the cooling guard 4, so as to take away as much heat as possible of the discharge port end of the cylinder 6 and the protection device 3, and prevent deformation and damage due to high temperature.

[0030] Further improvement is that the outer side of the cylinder 6 is further annularly provided with a cold air isolation sleeve 2, and one end of the cold air isolation sleeve 2 is connected with one end of the protection plate 7.
