Description
Technical field
The utility model relates to granulator accessories fields, and in particular to sealing structure between a kind of flange.
Background technique
Existing drying and granulating machine, mostly uses greatly upper cylinder body to connect to form container with lower cylinder body, upper cylinder body and lower cylinder body point
Not by upper and lower flanged joint, and airtight sealed structure is set between upper lower flange, and existing airtight sealed structure is filling
After hermetic seal, which can have one between upper lower flange between lower flange and airtight sealed structure
Section spacing, and this section of distance is easy sedimentating dust, causes cleaning effect bad, cannot achieve on-line cleaning.
Utility model content
In view of the above-mentioned problems, the utility model provides sealing structure between a kind of flange.
To achieve the above object, the utility model provides sealing structure between a kind of flange comprising is arranged on upper cylinder body
Upper flange and the lower flange that is arranged on lower cylinder body, upper flange and lower flange be oppositely arranged, the upper flange is equipped with close
Sealing groove, is arranged gas-flow closure circle in the seal groove, and the inside edge of the lower flange is filled in the middle part of gas-flow closure circle
The gas-flow closure circle of compressed air extends the opening of seal groove, and formation abuts with lower flange and can coat lower flange inward flange
Sealing surface.
Oblique angle is arranged in the inward flange of the upper flange.
Oblique angle is arranged in the inward flange of the lower flange.
The distance between the upper flange and lower flange are the half of the swell increment of air sealing ring.
Air sealing ring bottom is fixedly connected by being equipped with the bolt of hollow conduit with upper flange.
The stud base is threadedly coupled with gas nozzle.
The upper cylinder body is welded and fixed with upper flange, and the lower cylinder body is welded and fixed with lower flange.
The utility model has the beneficial effects that lower flange inward flange is located at the middle part of gas-flow closure circle, so that after inflation
Gas-flow closure circle can envelope on the inside of lower flange, to guarantee in operation process that dust will not enter and be deposited in Flange Plane.
Detailed description of the invention
Fig. 1 is the structural schematic diagram before the utility model sealing.
Fig. 2 is the structural schematic diagram after the utility model sealing.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, fall within the protection scope of the utility model.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
In the present invention unless specifically defined or limited otherwise, term " connection ", " fixation " etc. should do broad sense reason
Solution, for example, " fixation " may be a fixed connection, may be a detachable connection, or integral；It can be mechanical connection, it can also
To be electrical connection；It can be directly connected, the connection inside two elements can also be can be indirectly connected through an intermediary
Or the interaction relationship of two elements, unless otherwise restricted clearly.It for the ordinary skill in the art, can be with
The concrete meaning of above-mentioned term in the present invention is understood as the case may be.
In addition, the description for being such as related to " first ", " second " in the present invention is used for description purposes only, and cannot manage
Solution is its relative importance of indication or suggestion or the quantity for implicitly indicating indicated technical characteristic.Define as a result, " the
One ", the feature of " second " can explicitly or implicitly include at least one of the features.In addition, the skill between each embodiment
Art scheme can be combined with each other, but must be based on can be realized by those of ordinary skill in the art, when technical solution
It will be understood that the combination of this technical solution is not present in conjunction with there is conflicting or cannot achieve when, also not in the utility model
It is required that protection scope within.
The utility model provides sealing structure between a kind of flange comprising the upper flange 2 that is arranged on upper cylinder body 1 and sets
The lower flange 4 on lower cylinder body 5 is set, upper flange and lower flange are oppositely arranged, and the upper flange is equipped with seal groove 6, described
Gas-flow closure circle 3 is set in seal groove, and the inward flange 9 of the lower flange is in the middle part of gas-flow closure circle, is filled with compressed air
Gas-flow closure circle extend the opening of seal groove, form the sealing surface that lower flange inward flange is abutted and can coated with lower flange.
Lower flange inward flange must be located at the middle part of gas-flow closure circle, and gas-flow closure circle after inflation is enveloped in lower flange
Side is deposited in Flange Plane with guaranteeing in operation process that dust will not enter.
Seal groove is arranged in upper flange bottom side, is difficult to clear up after groove can be entered to avoid dust.
Oblique angle is arranged in the inward flange of the upper flange, and oblique angle is arranged in the inward flange of the lower flange.Upper lower flange inward flange
The suitable oblique angle of palpus a homogeneous example showing an inverse connection between the middle term and the major term enables cleaning water flow along inclined-plane sputtering, is flushed to gas-flow closure circle, to realize to gas-flow closure
The on-line cleaning of circle.
The distance between the upper flange and lower flange are the half of the swell increment of air sealing ring, to guarantee inflation
The validity sealed afterwards.
Air sealing ring bottom is fixedly connected by being equipped with the bolt 7 of hollow conduit with upper flange.The bolt bottom
Portion is threadedly coupled with gas nozzle 8.Using the bolt with hollow conduit, inflation seal ring can be fixed on to sealing trench bottom,
It prevents it from falling, while can use hollow conduit and filling compressed gas into gas-flow closure circle, its expansion is made to realize sealing.
The upper cylinder body is welded and fixed with upper flange, and the lower cylinder body is welded and fixed with lower flange, solid using welding manner
Fixed, so that the two fixation is stronger, sealing performance is more preferable.
Embodiment is not construed as limitations of the present invention, but changes made by any spirit based on the utility model
Into should all be within the protection scope of the utility model.
