Embodiment Construction
[0008] now attached figure 1 The present invention is described further:
[0009] as attached figure 1 As shown, the cylinder labyrinth seal ring 6 and the flange 2 are respectively welded on the cylinder body 1, the movable labyrinth seal ring 3 and the cylinder labyrinth seal ring 6 form a labyrinth seal pair with a small gap, and the flange 2 is evenly drilled. There are a plurality of screw holes, bolts 7 and nuts 8 are installed, the bolts 7 withstand the rear end face of the movable labyrinth sealing ring 3, the movable labyrinth sealing ring 3 is set in the sealing cover 4, and the soft connection sealing cover 5 can be freely expanded and contracted. The ends are fixed on the movable labyrinth sealing ring 3 and the sealing cover 4 with bolts respectively, and the insides of the movable sealing ring 3 and the sealing cover 4 are separated. When the rotary kiln is working, the cylinder expands and elongates when heated, and the bolt 7 withstands the movable labyrinth ...

A barrel end sealing device for rotary kiln is characterized by comprising a barrel body maze seal ring, a movable maze seal ring, a seal shield, and a soft connecting seal shield, wherein the barrel body maze seal ring is arranged at the end of the barrel body; the maze seal ring and the movable maze seal ring are matched with each other to form a maze type sealing; the movable maze seal ring is placed on the seal shield; two ends of the soft connecting seal shield are fixed onto the movable maze seal ring and the seal shield respectively to separate the movable maze seal ring and the seal shield from inside; a flange is arranged on the barrel body, on which a plurality of screw holes are bored; bolts and nuts are mounted, and the bolts support the movable maze seal ring. The barrel end sealing device has the advantage that when the rotary kiln runs, the barrel extends due to heating, and the bolts mounted on the barrel body flange can support the movable maze seal ring, so that the movable maze seal ring can move along with the rotary kiln; the clearance between the movable maze seal ring and the maze seal ring of the barrel end remains unchanged, so that the seal effect is ensured.
Description
technical field [0001] The invention relates to a sealing device, in particular to a cylinder end sealing device of a rotary kiln. Background technique [0002] At present, the cylinder end sealing device of the known rotary kiln adopts a labyrinth seal. Since the rotary kiln works at high temperature, as the temperature rises, the cylinder end will extend, and some rotary kiln cylinder ends can even extend to hundreds of mm. At this point the effect of the labyrinth seal becomes very poor. Contents of the invention [0003] The object of the present invention is to provide a cylinder end sealing device of a rotary kiln, which overcomes the disadvantage of the original sealing device of the rotary kiln having poor sealing effect due to thermal expansion and extension. [0004] A cylinder end sealing device for a rotary kiln, characterized in that it includes a cylinder labyrinth seal ring, a movable labyrinth seal ring, a seal cover, a soft connection seal cover, and a c...
