Accompanying drawing explanation
Fig. 1 is the structural representation of the vacuum carrying roller of a kind of paper machine of the present invention;
Fig. 2 be Fig. 1 B-B to cross-sectional schematic;
Fig. 3 is the structural representation of sealing device of the present invention.
Detailed description of the invention
According to drawings and embodiments the present invention is described in further detail below.
As Fig. 1, Fig. 2, shown in Fig. 3, the vacuum chamber of the vacuum carrying roller of the paper machine described in the embodiment of the present invention, comprise vacuum tank 2, vacuum tank is arranged in roll body 1, the two ends of vacuum tank 2 are connected to transmission side vacuum tank head 6 and fore side vacuum tank head 7, one end of transmission side vacuum tank head 6 is connected with suction mouth 10, vacuum tank 2 is evenly provided with some water sucking mouths 11 vertically, vacuum tank is provided with sealing device near roll body inwall end, sealing device comprises end seal 12 and axial sealer 13, end seal 12 is arranged on the two ends of vacuum tank 2 along the circular arc of vacuum tank 2, axial sealer 13 is axially arranged along the edge of water sucking mouth 11, end seal 12 and axial sealer 13 coordinate and water sucking mouth 11 can be surrounded, sealing device coordinates with vacuum tank 2 and forms vacuum chamber, vacuum tank 2 comprises a semi-circular top and one and half orthohexagonal bottoms, the sidewall of vacuum tank 2 is provided with the water jet 14 to roll body 1 inwall water spray, water jet 14 is separately positioned on the two side bottom vacuum tank 2, fore side vacuum tank head 7 is provided with sparge pipe 16, sparge pipe 16 is connected with water jet 14, a roller devices 15 is provided with immediately below bottom vacuum tank 2.
