Abstract
The utility model discloses a dry gas sealing device for a stirred tank, which comprises a stirred tank cavity, a dry gas seal, a first stationary ring seat and a second stationary ring seat, wherein the dry gas seal is fixedly connected with a rotating ring seat; the lower end of the rotating ring seat is connected with the first stationary ring seat, and the rotating ring seat is connected with a shaft sleeve; the first stationary ring seat is internally connected with a spring; the inner side of the dry gas seal is provided with a nitrogen inlet; the upper side of the dry gas seal is connected with a pressing sleeve; the pressing sleeve is fixedly connected with the second stationary ring seat; a sealing O-shaped ring is fixed in the second stationary ring seat; and the upper end of the stirred tank cavity is connected with the second stationary ring seat, and the lower end of the stirred tank cavity is connected with the first stationary ring seat. The dry gas sealing device for the stirred tank has the advantages of zero leakage of process media, low power consumption, high anti-axle swing performance and the like.
Description
Technical field
The utility model relates to chemical technology field, is specifically related to a kind of stirred tank dry gas sealing device.
Background technique
Now, Taiwan auspicious scape vertical mixer ISB0110 is different with the reactor that generally is used for low speed rotation, its rotating speed reaches 10000r/min, medium is the electrolytic solution with significant damage, this also just not only will guarantee that medium is not contaminated, also to guarantee not outside leakage pollution environment of medium, thus such stirred tank sealing be had higher requirement.
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: the dry gas sealing device how a kind of stirred tank is provided, this stirred tank dry gas sealing device has the processing medium zero leakage, little, the anti-axle of power consumpiton is swung advantages such as performance is strong, overcome the shortcoming of employed stirred tank sealing in the present industry, the motive sealing that stirred tank is sealed becomes static seal.A whole set of dry gas sealing device is simple to operation.
To achieve the above object of the invention, the technological scheme that the utility model adopted is: a kind of stirred tank dry gas sealing device is provided, comprises stirred tank cavity, dry gas seals, first stationary seat and second stationary seat; Described dry gas seals is connected and fixed rotating seat, and the rotating seat lower end connects first stationary seat, the rotating seat connecting bushing; Connect spring in described first stationary seat; Nitrogen inlet is established in described dry gas seals inboard, and the dry gas seals upside connects clamping sleeve, and clamping sleeve is connected and fixed second stationary seat, second stationary seat internal fixation sealing O type circle; Described stirred tank cavity upper end connects second stationary seat, and stirred tank cavity lower end connects first stationary seat.
Described dry gas seals is a kind of flute profile seal ring.
In sum, this stirred tank dry gas sealing device has advantages such as little, the anti-axle swing performance of processing medium zero leakage, power consumpiton is strong, has overcome the shortcoming that institute's stirred tank that uses seals in the present industry, and the motive sealing that stirred tank is sealed becomes static seal.A whole set of dry gas sealing device is easy to operate simple.

Fig. 2 is the sectional view of dry gas seals;
Wherein, 1, stirred tank cavity; 2, first stationary seat; 3, spring; 4, dry gas seals; 5, rotating seat; 6, clamping sleeve; 7, sealing O type circle; 8, axle sleeve; 9, second stationary seat; 10, nitrogen inlet.
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 stirred tank dry gas sealing device comprises stirred tank cavity 1, dry gas seals 4, first stationary seat 2 and second stationary seat 9; Described dry gas seals 4 is connected and fixed rotating seat 5, and rotating seat 5 lower ends connect first stationary seat 2, rotating seat 5 connecting bushings 8; Connect spring 3 in described first stationary seat 2; Nitrogen inlet 10 is established in described dry gas seals 4 inboards, and dry gas seals 4 upsides connect clamping sleeve 6, and clamping sleeve 6 is connected and fixed second stationary seat, 9, the second stationary seats, 9 internal fixation sealing O type circle 7; Described stirred tank cavity 1 upper end connects second stationary seat 9, and stirred tank cavity 1 lower end connects first stationary seat 2; Described dry gas seals 4 is a kind of flute profile seal rings.
The nitrogen pressure of this stirred tank dry gas sealing device is higher than medium gas, and at the sealing normal operation period, the nitrogen trace leaks to side medium and atmospheric side; No matter whether sealing can normally move, and the medium that all can guarantee to have harmfulness can be to big gas leakage.
Because the running shaft high speed rotating when adopting spring static, can effectively guarantee the influence that is not subjected to high speed rotating of Packing spring elastic force, guarantees that with this dry gas seals can stable operation.
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.
