Description
Technical field
The utility model relates to the plastics-production technical field, is specifically related to a kind of dynamic separator dry gas sealing device.
Background technique
Now, existing mechanical seal end surface must be kept continuous lubricating liquid film could guarantee that sealing runs well, no matter adopting single end face still is the double seals structure, the pressure of its sealing fluid all will be higher than pressure medium could guarantee that processing medium is not toward external leakage, this certainly exists sealing fluid and leaks into medium, influence the purity of medium, severe patient even can cause full still inventory disposal causes huge waste and economic loss.What former sealing was adopted is the double mechanical seal that import Crane John Inc. produces, and along with user's requirement more and more higher to equipment, former mechanical seal can't be satisfied aspect energy-saving and environmental protection.
For solving the aforementioned problems in the prior, the utility model provides a kind of new solution.
Summary of the invention
The technical problems to be solved in the utility model is: how a kind of dynamic separator dry gas sealing device is provided, this dynamic separator dry gas sealing device has the processing medium zero leakage, to characteristics such as environment and processing medium be pollution-free, a whole set of dry gas sealing device has thoroughly been broken away from the dependence of traditional double end surface mechanical sealing to oil system, can stop sealing oil fully and enter processing medium and environment, leakage only be nitrogen or industrial instrument wind.
To achieve the above object of the invention, the technological scheme that the utility model adopted is: a kind of dynamic separator dry gas sealing device is provided, comprises carbocyclic ring sealing, one-level dry gas seals and secondary dry gas seals; The described carbocyclic ring carbocyclic ring sealing seat that is sealedly connected and fixed is established preposition blanket gas inlet in the carbocyclic ring sealing, preposition blanket gas inlet lower end connecting bushing, axle sleeve coupled reaction cavity; Described carbocyclic ring sealed upper end connects the one-level dry gas seals, primary seal gas inlet is established in described one-level dry gas seals inboard, one-level dry gas seals lower end connects first seal ring, the one-level dry gas seals is connected and fixed the sealed type circle, sealed type circle upper end connects first stationary seat, first leakage hole is established in the first stationary seat lower end, and first stationary seat is connected and fixed labyrinth seal; Described secondary dry gas seals lower end connects second seal ring, and the cushion gas inlet is established in the second seal ring inboard; Described secondary dry gas seals connects rotating seat, secondary dry gas seals upper end fixing spring, and the spring upper end connects second stationary seat; Establish second leakage hole on the described secondary dry gas seals.
According to dynamic separator dry gas sealing device provided by the utility model, it is characterized in that: described carbocyclic ring sealing, one-level dry gas seals, secondary dry gas seals be coupling shaft successively from top to bottom.
According to dynamic separator dry gas sealing device provided by the utility model, it is characterized in that: described first seal ring and second seal ring are a kind of flute profile spiral seal rings.
In sum, the dynamic separator dry gas sealing device has the processing medium zero leakage, to characteristics such as environment and processing medium be pollution-free, a whole set of dry gas seals has thoroughly been broken away from the dependence of traditional double end surface mechanical sealing to oil system, can stop sealing oil fully and enter processing medium and environment, leakage only be nitrogen or industrial instrument wind.Dynamic separator dry gas sealing device provided by the utility model can well adapt to the usage requirement of dynamic separator dry gas seals.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is done and to be described in detail:
As shown in the figure, this dynamic separator dry gas sealing device comprises carbocyclic ring sealing 3, one-level dry gas seals 6 and secondary dry gas seals 11; Described carbocyclic ring sealing 3 is connected and fixed carbocyclic ring sealing seat 4, establishes preposition blanket gas inlet 14 in the carbocyclic ring sealing 3, the preposition blanket gas 14 lower end connecting bushings 5 that enter the mouth, axle sleeve 5 coupled reaction cavitys 1; Described carbocyclic ring seals 3 upper ends and connects one-level dry gas seals 6, primary seal gas inlet 15 is established in described one-level dry gas seals 6 inboards, one-level dry gas seals 6 lower ends connect first seal ring 19, one-level dry gas seals 6 is connected and fixed sealing O type circle 7, sealing O type circle 7 upper ends connect first stationary seat 8, the first stationary seat lower end is established first leakage hole, 16, the first stationary seats 8 and is connected and fixed labyrinth seal 9; Described secondary dry gas seals 11 lower ends connect second seal ring, 20, the second seal rings, 20 inboards and establish cushion gas inlet 17; Described secondary dry gas seals 11 connects rotating seat 10, secondary dry gas seals upper end fixing spring 12, and spring 12 upper ends connect second stationary seat 13; Establish second leakage hole 18 on the described secondary dry gas seals; Described carbocyclic ring sealing 3, one-level dry gas seals 6, secondary dry gas seals 11 be coupling shaft 2 successively from top to bottom; Described first seal ring 19, second seal ring 20 are a kind of flute profile spiral seal rings.
Preposition blanket gas of this dynamic separator dry gas sealing device and primary seal atmospheric pressure are higher than medium gas, add preposition carbocyclic ring seal action, guarantee the cavity interior most of be blanket gas (clean propylene gas) of primary seal--prevent that powder from entering primary seal, primary seal is worn and torn too early, thereby cause whole seal failure; Cushion gas pressure is lower than blanket gas pressure, adds the effect of upper level labyrinth seal, makes the blanket gas (clean propylene gas) that only contains small leakage in the cavity of secondary seal and cushion gas (nitrogen) in a large number.Be discharged to torch burning by the one-level leakage hole.By secondary seal, have only a small amount of cushion gas (nitrogen), reveal mouthful row to atmosphere by secondary, nitrogen does not pollute atmosphere.
The utility model is not limited to above-mentioned example, in claims of the present utility model institute restricted portion, and various distortion that those skilled in the art can make without creative work or revise the protection that all is subjected to this patent.
