The differential pressure gauge 2 is used to measure and display the pressure difference between the cross-cutting area 12 and the processing area 11. The side of the kiln 1 is connected to an exhaust duct 3, and the other end of the exhaust duct 3 is connected to a return air duct 4. The exhaust duct 3 is connected to an exhaust fan 6 via a hose 5. The exhaust volume is controlled by controlling the fan frequency of the exhaust fan 6, thereby controlling the pressure difference between the cross-cutting area 12 and the processing area 11. The exhaust duct 3 is a galvanized air duct.
[0022] In order to facilitate the connection between the exhaust duct 3 and the exhaust fan 6, a through hole is provided on the side of the exhaust duct 3, and the hose 5 is connected to the through hole through the connecting component 7. Figure 2 and Figure 3As shown, the connecting assembly 7 includes a clamp 71, a sealing plug 72, a connecting disk 73, a connecting pipe 74, a locking plate 75, a locking nut 76 and a locking screw 77; the clamp 71 adopts a circular ring structure with an opening, and both ends of the opening of the clamp 71 are connected to locking plates 75; locking holes are provided on the surfaces of the two locking plates 75, and the locking holes are matched to connect locking screws 77; the locking screws 77 are threadedly connected to the locking nut 76; a sealing plug 72 is fixed to the inner side of the clamp 71, and a connecting pipe 74 is inserted and fixed between the sealing plug 72 and the clamp 71; the connecting pipe 74 is matched to connect the through hole, and a connecting disk 73 is fixed to the side of the connecting pipe 74; a connecting disk 73 is provided on the side of the hose 5, and the connecting pipe 74 is matched to connect the hose 5, and the two connecting disks 73 are connected by bolts. When connecting the exhaust duct 3 and the exhaust fan 6, the connecting pipe 74 is inserted into the through hole on the side of the exhaust duct 3, and the connection between the connecting pipe 74 and the exhaust duct 3 is sealed with the sealing plug 72. Then, the hose 5 is inserted into the connecting pipe 74, and the hose 5 and the connecting plate 73 on the side of the connecting pipe 74 are used to lock them with bolts, so that the exhaust duct 3 and the hose 5 are connected through the connecting assembly 7, which makes it easy to replace the hose 5 when it is damaged.
[0023] The sealing plug 72 includes an arc portion 721 and an extending portion 722; the extending portion 722 is a circular ring structure, and the side of the extending portion 722 is provided with an arc portion 721; the arc portion 721 cooperates with the connecting through hole to ensure the sealing of the connection between the connecting tube 74 and the exhaust duct 3.
