Abstract
The utility model relates to a hermetic sealing device, which is characterized by including at least an inflatable hermetic seal ring, wherein the inflatable hermetic seal ring is sleeved at the part of a bottle out-pushing rod positioned outside a freeze dryer box body, and the inflatable hermetic seal ring is arranged outside a hermetic seal flange. The hermetic sealing device has the benefits that as a reliable sealing method is provided, the air tightness of a corrugated pipe can be sufficiently verified, and the freeze-dried medicine can be ensure to be aseptic.
Description
Technical field
This practicality relates to a kind of sealing that aims at vacuum freeze drier self-emptying mechanism, and the sealing device is to realize sealing to the bellows of kick-off arm, thereby verifies the tightness of bellows.
Background technique
Self-emptying mechanism is used for releasing the outside mechanism of vacuum freeze drier to the cillin bottle after the vacuum freeze drier freeze-drying, and wherein this mechanism includes main parts size such as kick-off arm, metal bellows.
There is drawback in the sealing to the self-emptying mechanism of existing vacuum freeze drier at present:
1, the sealing of the self-emptying mechanism of usefulness now is to adopt seal with O ring, because the bottle outlet push rod is to do straight line motion, so friction is big, the life-span of use is very short, continuous and must change seal ring, has reduced manufacturing efficiency.
2, because of adopting seal with O ring, its sealing effect is poor, does not reach bellows and verifies needed degree of vacuum, so just can accurately not judge the tightness of bellows, thereby can't verify the quality of bellows, and this brings very big pollution risk for the freeze-drying medicine.
Summary of the invention
The purpose of the utility model provides a kind of sealing configuration that is exclusively used in the self-emptying mechanism of vacuum freeze drier, and the sealing structure can be verified the quality of bellows.
In order to achieve the above object; The technological scheme of the utility model has provided a kind of gas sealing mechanism; It is characterized in that: comprise at least one inflatable airtight seal; Inflatable hermetic seal snare is outside the bottle outlet push rod is positioned at the part of freeze dryer casing, and inflatable airtight seal places outside the hermetic seal flange.
Further, said inflatable airtight seal connects a solenoid valve.
In said hermetic seal flange, have the groove that is used to hold said inflatable airtight seal.
Said inflatable airtight seal is at least two.
The inside of said inflatable airtight seal is hollow.
The beneficial effect of the utility model is: a kind of reliable sealing means is provided, can have verified the tightness of bellows fully, thereby guaranteed the sterility of the medicine of institute's freeze-drying.
Description of drawings
The structural drawing of a kind of gas sealing mechanism that Fig. 1 provides for the utility model;
The fundamental diagram of a kind of gas sealing mechanism that Fig. 2 provides for the utility model;
The fundamental diagram that bellows is verified of a kind of gas sealing mechanism that Fig. 3 provides for the utility model.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
In Fig. 1, hermetic seal flange 1 is a container, in its indoor design two hermetic seal grooves is arranged, and it is inner that inflatable airtight seal 2 is placed on this flange, is the carrier of airtight seal.Inflatable airtight seal 2 is core components of this device; It is a kind ofly to have an elastomeric seal ring with what silicone rubber was made into; Be hollow in inside specifically, similar with the shape of tire, its inside can charge into pressurized air; So just can realize the expansion function of seal ring, utilize this expansion function to realize the effect that seals just.For the reliability that realizes sealing, be designed with two airtight seal in the present embodiment.Freeze dryer casing 3 is the containers that carry out freeze-dry process, and the cillin bottle of institute's freeze-drying carries out in this container, and box house completely cuts off with extraneous in the process in freeze-drying, will effectively realize the protection of freeze-drying medicine like this.Bottle outlet push rod 4 is functions of carrying out bottle outlet, and this bar can seesaw under the driving of motor, good cillin bottle release freeze dryer casing 3 outsides of institute's freeze-drying.The function of bellows 5 is to isolate inner with the outside barrier of freeze dryer; It is a kind of retractable metallic hose, and its end and bottle outlet push rod 4 are fixing, and an end is connected with freeze dryer casing 3; The quality of this pipe is related to the degree to drug protection; If breakage then directly damages the medicine of institute's freeze-drying,, know with this whether bellows is intact so want the regular checking of carrying out bellows.Freeze dryer flaggy 6 is in the freeze dryer casing, and upper surface is the plane of placing cillin bottle, also is the main carrier of freeze-dry process process.Solenoid valve 7 is control valves that gas gets into, and opens this valve in the time of inflating, and gas enters into airtight seal and carries out sealing function.
In Fig. 2; This process is that inflatable airtight seal 2 is not worked in this process in the process of bottle outlet push rod 4 work, and solenoid valve 7 is in the state of shutoff; Inflatable airtight seal 2 inside do not have compressed-air actuated charging into; Inflatable airtight seal 2 is in nature, has certain clearance between bottle outlet push rod 4 and the inflatable airtight seal 2 like this, so friction phenomenon can not take place between they the two; Do not resemble the O-ring seals and bottle outlet push rod 4 fitting together tightly, cause the frictional force between the two very big.Since not friction relatively between inflatable airtight seal 2 and the bottle outlet push rod 4, so the working life of airtight seal is very long, the airtight seal that more renews that need not be frequent.
In Fig. 3, bellows 5 need determine whether intact in use for some time, so just need verify bellows 5; This process be bottle outlet push rod 4 not in the course of the work, remain static, this moment solenoid valve 7 open; Inflatable airtight seal 2 charges into the pressurized air of certain pressure, and inflatable airtight seal 2 this moment just can be expanded, because the existence of hermetic seal flange 1; The outer wall of inflatable airtight seal 2 just can tightly be attached on each inwall of periphery, particularly can tightly embrace bottle outlet push rod 4, realizes sealing function completely; As shown in the figure, the inner chamber A space of bellows 5 just is isolated from the outside, and the inner chamber to bellows 5 vacuumizes then; Carry out pressurize after reaching certain degree of vacuum, verify the quality of bellows, if the variation of degree of vacuum takes place through pressure gauge and verifying software; Because airtight seal is in sealing state, occur damaging the bellows that more renews timely so just can judge bellows 5; Thereby avoid institute's freeze-drying medicine to be polluted, improved the reliability of medicine.
