[0031] Wherein, a large amount of slag slurry touches the inner wall of conical part 101 when discharging, since the shape of conical part 101 is conical, the slag slurry will impact the inner wall of conical part 101 when passing, causing the inner wall of conical part 101 to wear, and the conical part 101 is prone to leakage after long-term use, and corundum is used.

[0032] By providing inner protection piece 201 on the inner wall of conical part 101, the slag slurry impacts the inner protection piece 201, and since the corundum material has better wear resistance, the conical part 101 is not easily worn through.

[0033] By providing outer protective sleeve 301 on the outer wall of conical part 101, the center of outer protective sleeve 301 is located at the most impacted position of conical part 101 by slag slurry, and when conical part 101 is worn through, outer protective sleeve 301 can protect conical part 101 externally when leakage occurs, and the leaked slag slurry will enter the hollow cavity 302.

[0034] During use, the slag slurry enters the conical part 101 from the cyclone 100 and impacts the inner protection piece 201 on the inner wall of the conical part 101, the inner protection piece 201 and the conical part 101 guide the slag slurry to be discharged below, the inner protection piece 201 replaces the conical part 101 to bear the wear, even if the inner protection piece 201 is worn through, the outer protective sleeve can still protect the conical part 101 externally, and when the conical part 101 is worn through, since the slag slurry can enter the hollow cavity 302, until the hollow cavity 302 is filled, the subsequent slag slurry will impact the accumulated slag slurry, and it is not easy to wear through the outer protective sleeve 301.

[0035] Embodiment 2

[0037] During use, the corundum wear-resistant layer 201a is a layer structure covering the inner wall of the conical part 101, and the addition of the corundum wear-resistant layer 201a can effectively increase the wear resistance without changing the structure of the conical part 101.

[0038] The remaining structure is the same as that of embodiment 1.

[0039] Embodiment 3

The top of the corundum wear-resistant sleeve 201b can also be provided with an inclined notch (not shown in the figure) for attaching to the taper part 101 and preventing the material from entering the taper part 101. With the impact of the material on the corundum wear-resistant sleeve 201b, the corundum wear-resistant sleeve 201b will be more tightly pressed against the inner wall of the taper part 101.

[0042] The remaining structure is the same as that of embodiment 1.

[0052] The rest of the structure is the same as that of the first embodiment.
