Abstract
The utility model discloses a seal device of a rotary kiln, which comprises a seal plate, a maze-type seal and a support seat and is characterized in that the support seat is arranged on the periphery of the rotary kiln, the seal plate is arranged on the periphery of the support seat, one end of the seal plate is in contact with the support seat through an anti-wear ring, the other end of the seal plate is fixed on the outer wall of the maze-type seal, the middle section of the seal plate is provided with a spring connected with the outer wall of the maze-type seal, and a traverse baffle is arranged in a cavity of the maze-type seal. The structure that the elastic seal plate is matched with the maze-type seal with the additional traverse baffle is adopted, and the seal performance of the seal plate and the support seat is improved so that leakage of air and materials, reduction of heat consumption and safe and stable operation of the safety rotary kiln are benefited. Additionally, the rotary kiln is convenient to maintain.
Description
Technical field
The utility model relates to the rotary kiln field, relates in particular to a kind of seal of rotary kiln device.
Background technology
Rotary kiln is as the visual plant of burning clinker of cement, under its normal operating conditions, because relative motion and the small axial displacement of rotary kiln tube between each parts of rotary kiln; Add gravity effect; The gap very easily appears revealing in general labyrinth type seal of rotary kiln device, and receives the influence of its working environment, and the natural wastage of sealing device also can bring the generation of the material that leaks out; Also can increase hear rate, contaminated environment simultaneously.
Summary of the invention
In order to overcome the defective of existing seal of rotary kiln device, the utility model aims to provide a kind of seal of rotary kiln device that can effectively improve its sealing effectiveness.
The purpose of the utility model realizes through following embodiment.
A kind of seal of rotary kiln device comprises sealing plate, labyrinth sealing and supporting seat, it is characterized in that: in rotary kiln tube periphery supporting seat is set; The supporting seat periphery is provided with sealing plate; Said sealing plate one end contacts with supporting seat through wear ring, and the other end is fixed in the labyrinth sealing outer wall, and the sealing plate stage casing is provided with spring; Spring is connected with the labyrinth sealing outer wall, in the said labyrinth sealing cavity deflection plate is set.
According to above-described a kind of seal of rotary kiln device, it is characterized in that: said spring all is connected by bolt with the labyrinth sealing outer wall with sealing plate, spring, and said deflection plate is four pairs of steel loops.
The utlity model has such advantage: the effect of spring tension, it is tightr that sealing plate is contacted with supporting seat, reduces gravity and the influence that each parts relative motion brings, and improved sealing effectiveness; The setting of wear ring makes the sealing device life-span more of a specified duration; In the labyrinth sealing cavity, deflection plate is set, further improves sealing effectiveness; Bolt connects, easy access.
Description of drawings
Fig. 1 is the structural representation of a kind of seal of rotary kiln device of the utility model embodiment.
The specific embodiment
The explanation of mark among Fig. 1:
1---the rotary kiln tube, 2---supporting seat, 3---wear ring, 4---sealing plate, 5---bolt, 6---spring, 7---labyrinth sealing, 8---deflection plate, 9---the labyrinth sealing cavity.
Below in conjunction with accompanying drawing the utility model embodiment is elaborated.
As shown in Figure 1, a kind of seal of rotary kiln device comprises sealing plate 4, labyrinth sealing 7 and supporting seat 2, and supporting seat 2 is arranged on rotary kiln tube 1 periphery, and sealing plate 4 is arranged on supporting seat 2 excircles.Sealing plate 4 one ends contact with supporting seat 2 through wear ring 3, and the other end is fixed in labyrinth sealing 7 outer walls, and sealing plate 4 stage casings are provided with spring 6, and spring 6 is connected with labyrinth sealing 7 outer walls, and the quantity of said spring 6 can increase and decrease according to sealing requirements; Four pairs of deflection plates 8 are set in the labyrinth sealing cavity 9.
When rotary kiln tube rotation or each parts had relative motion, sealing plate 4 can keep its wear ring 3 to contact with the tight of supporting seat 2 under spring 6 tension, the sealing effectiveness of assurance sealing device.
Four pairs of deflection plates 8 that are provided with in the labyrinth sealing cavity 9 can produce throttle effect to the air-flow of flowing through on it, increase the resistance to gas flow, and flow velocity is reduced, and further improve the sealing effectiveness of sealing device.
The seal of rotary kiln device of the utility model under elastic packing plate and labyrinth sealing acting in conjunction, has improved Sealing of Rotary Kiln property, for minimizing leak out material, reduce hear rate, the protection environment has positive effect.
At last; Be noted that; Above content is only in order to explain a kind of technical scheme of the utility model; But not to the restriction of the utility model protection domain, the simple modification that those skilled in the art carries out the technical scheme of the utility model or be equal to replacement does not all break away from the essence and the scope of the utility model technical scheme.
