The pipe shell 21 is provided with a guide plate 23 at one end close to the main unit 1, and the pipe shell 21 is provided with a connecting pipe 24 and a curtain 32 in sequence at one end close to the connecting part 3. The third explosion-relief port 22 is welded to the pipe shell 21, and a curtain 32 is provided in the middle of the third explosion-relief port 22 for relieving the pressure of the pressurized gas in the pipe.

[0041] Specifically, in this embodiment, the connecting portion 3 includes a frame 31 and a curtain 32, the frame 31 is connected to the frame 31 through fasteners, and the curtain 32 and the curtain 32 on the connecting pipe 24 are connected to each other through negative pressure in the pipe.

[0042] Between the above-mentioned connecting part 3 and the first pipe 2, a rubber curtain 32 is provided at the connecting position of the first pipe 2 and the connecting part 3, forming a sealing structure of the dust removal pipe. When the scrap metal crusher is operating normally, the two are connected to each other through the rubber curtain 32, and the connection position is not fixed. However, due to the existence of negative pressure in the dust removal pipe of the scrap metal crusher, the rubber curtain 32 at the connection position will be tightly fitted to ensure that dust during the operation of the crusher equipment cannot overflow from the dust removal equipment, thereby ensuring the personal safety of on-site personnel and efficiently and conveniently maintaining the dust removal equipment to improve production efficiency.

[0043] Specifically, in this embodiment, the end of the frame 31 close to the connecting pipe 24 is a rectangular frame, the end of the frame 31 close to the bent pipe 51 is a circular frame, and the frame 31 and the bent pipe 51 are connected by fasteners.

[0044] Specifically, in this embodiment, the bent pipe 51 includes multiple groups of first guardrails 511 and first explosion relief ports 512, and multiple first explosion relief ports 512 are welded on the bent pipe 51.
