Abstract
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
The present invention relates to a kind of sealing device, relate in particular to a kind of cylinder end sealing device of rotary kiln.
Background technology
What the cylinder end sealing device of present known rotary kiln adopted is labyrinth sealing, and because rotary kiln is at high temperature worked, along with the rising of temperature, extending can appear in the cylinder end, and some rotary kiln cylinder ends even can extend to millimeters up to a hundred.The effect of labyrinth seal this moment becomes very poor.
Summary of the invention
The object of the present invention is to provide a kind of cylinder end sealing device of rotary kiln, overcome original seal of rotary kiln device and be subjected to heat expansion to extend the poor shortcoming of sealing effectiveness.
A kind of cylinder end sealing device of rotary kiln, it is characterized in that: comprise cylindrical shell labyrinth seal, movable labyrinth seal, seal closure, seal closure is flexible coupling, be provided with the cylindrical shell labyrinth seal in the termination of cylindrical shell, this labyrinth seal coordinates formation labyrinth sealing with movable labyrinth seal, movable labyrinth seal is placed on seal closure, separately is provided with a flange on cylindrical shell, and the above is drilled with a plurality of screws, bolt and nut are installed, and this bolt withstands movable labyrinth seal.
A kind of cylinder end sealing device of rotary kiln, it is characterized in that: the two ends of the seal closure that is flexible coupling are separately fixed on movable labyrinth seal and seal closure.
The invention has the beneficial effects as follows when rotary kiln work, cylindrical shell is heated when extending, the bolt of installing on shell flange withstands movable labyrinth seal, make movable labyrinth seal follow mobile, the labyrinth seal ring gap of movable labyrinth seal and cylindrical shell termination remains unchanged, thereby has guaranteed sealing effectiveness.The present invention has simple in structure, and good sealing effect is not subjected to the impact of rotary kiln operating temperature, the advantage that sealing effectiveness is stable.
Description of drawings
Fig. 1 is structural representation of the present invention;
1. cylindrical shell, 2. flange, 3. movable labyrinth seal, 4. seal closure, the seal closure that 5. is flexible coupling, 6. cylindrical shell labyrinth seal, 7. bolt, 8. nut.
The specific embodiment
Now 1 the invention will be further described by reference to the accompanying drawings:
As shown in Figure 1, cylindrical shell labyrinth seal 6 and flange 2 are welded in respectively on cylindrical shell 1, movable labyrinth seal 3 forms the less labyrinth sealing pair in gap with cylindrical shell labyrinth seal 6, be drilled with equably a plurality of screws on flange 2, bolt 7 and nut 8 are installed, bolt 7 withstands the rear end face of movable labyrinth seal 3, movable labyrinth seal 3 is enclosed within seal closure 4, seal closure 5 retractables are flexible coupling, its two ends are fixed by bolts to respectively on movable labyrinth seal 3 and seal closure 4, and the inside of movable sealing circle 3 and seal closure 4 is separated.When rotary kiln is worked, the elongation of cylindrical shell expanded by heating, bolt 7 withstands movable labyrinth seal 3 and follows cylindrical shell 1 and move, thereby guaranteed the labyrinth seal effect of cylindrical shell labyrinth seal 6 and movable labyrinth seal 3, and the seal closure 5 that is flexible coupling equally also extends, make movable labyrinth seal 3 open with seal closure 4 internal insulation, thereby guaranteed good sealing effectiveness.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention; make without departing from the inventive concept of the premise some alternative or obvious modification that are equal to; and performance or purposes identical, should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
