Description
Technical field
The utility model relates to a kind of gland seal device on disposable biological engineering craft bags.
Background technique
In the R & D and manufacture processing procedure of bio-pharmaceuticals, bioreactor is a kind of vital equipment, the medicine gone on the market in the market is substantially all adopt stirring type bioreactor to produce, but traditional stirring type stainless steel bioreactor should it be sterilized, sterilizing, the processes such as checking are more loaded down with trivial details, relatively fixing to the demand in place, more to the requirement of periphery accessory, the factors such as between batch setup time is longer, to research and development, production etc. are movable exists suitable restriction, therefore the use of disposable bioreactor in this field is also increasingly common, the acceptance level in market is also high, at present, the research and development great majority of Novel medicine are all adopt the disposable bioreactor of foreign brand name to carry out, a kind of gland seal device on disposable biological engineering craft bags that the utility model relates to, can solve preferably and adopt disposable stirring type bioreactor to carry out aseptic, the problem of efficient cultivation, also aseptic dosing can be widely used in, the techniques such as mixed processing.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of gland seal device on disposable biological engineering craft bags.
For solving above-mentioned existing technical problem, the utility model adopts following scheme:
A kind of gland seal device on disposable biological engineering craft bags, it comprises shell, two bearings, hollow shaft, 4 S type Sealings, O type Sealing, stuffing box gland, spring, jump ring, shell and upper cover form a space, in space, two bearings are installed, hollow shaft is through upper cover and shell and be fixed on two bearings, by the lower end surface of jump ring by a S shape Sealing and housing, by jump ring, a S type Sealing is arranged on and upper cover, a plane sealing slided is formed between two S type Sealings and stuffing box gland, 2 layers of O type Sealing are provided with between stuffing box gland and housing.Rubber pipe and paddle connect as one and rubber sleeve on the rotating shaft, rotatingshaft is connected with hollow shaft.
This device and disposable craft bags are welded together, forms a container going for bioengineering and cultivate.
During work, in craft bags, malleation is kept to the lower end surface of whole gland seal device, when hollow shaft rotates, four S shape Sealings rotate together with axle, the lower end surface of a S shape Sealing and housing, a S type Sealing is arranged on and upper cover, a plane sealing slided is formed between two S type Sealings and stuffing box gland, because of the wear resistance of S shape Sealing, elasticity is better, use even if long-time and have wearing and tearing, the structure of S shape Sealing and the good compensate for wear part of elastic force interaction energy, thus sealing effect is good, suppose there is a small amount of breakthrough of gas S shape Sealing, two-layer O type Sealing is provided with between stuffing box gland and housing, form two-layer linear sealing, 6 groups of sealing layers are altogether constituted with four S shape Sealings, thus the operationally positive confinement of disposable craft bags can be ensured.
Beneficial effect:
Gland seal device described in the utility model can solve disposable stirring type bioreactor culture vessel internal mix and dosing preferably, mechanical agitation is carried out in mixed processing bag inside, it installs simple, convenient, can realize the aseptic quick connection between pto＝power take-off, paddle, Work container reliably.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is gland seal device structural representation.
Embodiment
As shown in Figure 1, 2, the utility model is a kind of gland seal device on disposable biological engineering craft bags, there is shell 6, bearing 5,10, hollow shaft 1, S type Sealing 3,13,14,15, O type Sealing 11, stuffing box gland 12, spring 8, jump ring 16,2, upper cover 4, halfround bar slice 7, pad 9, rubber pipe 17, rotatingshaft 18, paddle 19 form a space.In space, two bearings 5,10 are installed, hollow shaft 1 is through upper cover 4 and shell 6 and be fixed on two bearings 5,10, by the lower end surface of jump ring 16 by a S shape Sealing and housing, by jump ring 2, a S type Sealing 3 is arranged on and upper cover 4, form a plane sealing slided between two S type Sealings 13,14 and stuffing box gland 12, between stuffing box gland 12 and housing, be provided with 2 layers of O type Sealing 11.Rubber pipe 17 and paddle 19 connect as one and rubber pipe 17 is enclosed within rotatingshaft 18, and rotatingshaft 18 is connected with hollow shaft 1.Be provided with spring 8 between two bearings 5,10 and have pad 9 between spring and bearing 10.
This device and disposable craft bags 20 are welded together, forms a container going for bioengineering and cultivate.
As shown in Figure 2, during work, in craft bags, malleation is kept to the lower end surface of whole gland seal device, when hollow shaft 1 rotates, S shape Sealing 3/13/14/15 rotates together with axle 1, the lower end surface of S shape Sealing 15 and housing 6, S type Sealing 3 and upper cover 4, S type Sealing 13, a plane sealing slided is formed between 14 and stuffing box gland 12, because of the wear resistance of S shape Sealing, elasticity is better, use even if long-time and have wearing and tearing, the structure of S shape Sealing and the good compensate for wear part of elastic force interaction energy, thus sealing effect is good, suppose there is a small amount of breakthrough of gas S shape Sealing, this device is provided with 2 layers of O type Sealing 11 between stuffing box gland 12 and housing 6, form 2 layer line sealings, altogether constitute 6 groups of sealing layers (4 aspects seal 2 layer lines and seal) with S shape Sealing 3/13/14/15 thus the operationally positive confinement of disposable craft bags can be ensured.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
