Abstract
The utility model discloses a trapezoidal end of vacuum belt drier door seal structure, include: barrel flange and end door flange a dovetail has been seted up to the up end of barrel flange, the bottom contained angle alpha's of dovetail scope is 30~60 be provided with a trapezoidal sealing ring in the dovetail, the structure of trapezoidal sealing ring with the structure phase -match of dovetail, highly being greater than of trapezoidal sealing ring the degree of depth of dovetail, part that trapezoidal sealing ring stretches out the dovetail with end door flange is closely laminated, what trapezoidal sealing ring stretched out the dovetail part is 3mm~5mm apart from D. In this way, the utility model discloses can solve vacuum belt drier both sides end door sealing strip drops sealed not tight problem easily.
Description
Technical field
This utility model relates to food manufacture field, particularly relates to a kind of trapezoidal end door sealing structure of vacuum belt drier.
Background technology
What the end door of existing vacuum belt drier both sides adopted is circular or rectangular seal ring. Owing to the end door diameter of vacuum belt drier both sides is big, the gross weight of encapsulant is big, adopt circular and rectangle O ring sealing means, often result in sealing ring to come off when opening end door, when reinstalling, due to sealing ring employing is circular or rectangle, makes sealing ring not easily be fixed in seal groove. Connection with end door flange sealing trough loosens, and in foreign body meeting upstream end door sealing groove, foreign body is piled up, and causes end door seal failure. The maintenance work difficulty of sealing ring.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of trapezoidal end door sealing structure of vacuum belt drier, it is possible to solves vacuum belt drier two side ends door weather strip and easily comes off, poorly sealed problem.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of trapezoidal end door sealing structure of vacuum belt drier, including: shell flange and end door flange, a dovetail groove is offered in the upper surface of described shell flange, the bottom angle �� of described dovetail groove range for 30 �� ~ 60 ��, a trapezoidal sealing ring it is provided with in described dovetail groove, the structure of described trapezoidal sealing ring and the structure of described dovetail groove match, the height of described trapezoidal sealing ring is more than the degree of depth of described dovetail groove, described trapezoidal sealing ring stretches out the part of dovetail groove and fits tightly with described end door flange, it is 3mm ~ 5mm that described trapezoidal sealing ring stretches out the distance D of dovetail groove part.
Preferably, the bottom angle �� of described dovetail groove is 30 ��, and now trapezoidal sealing ring is tightr with contacting of dovetail groove, has better seal, trapezoidal sealing ring difficult drop-off.
Preferably, it is 3mm that described trapezoidal sealing ring stretches out the distance D of dovetail groove part, the better tightness of trapezoidal sealing ring and end door flange.
The beneficial effects of the utility model are: this utility model adopts the sealing structure of dovetail groove and trapezoidal sealing ring, relative to original circle or rectangular seal ring, seal more reliable, and simple in construction, it is easy to safeguard, improves the sealing between shell flange and end door flange.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model vacuum belt drier trapezoidal end door sealing structure one preferred embodiment;
In accompanying drawing, the labelling of each parts is as follows: 1, shell flange, and 2, end door flange, 3, trapezoidal sealing ring, 4, dovetail groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model being made apparent clear and definite defining.
Referring to Fig. 1, this utility model embodiment includes:
A kind of trapezoidal end door sealing structure of vacuum belt drier, including: shell flange 1 and end door flange 2, a dovetail groove 4 is offered in the upper surface of described shell flange 1, the bottom angle �� of described dovetail groove 4 range for 30 ��, a trapezoidal sealing ring 3 it is provided with in described dovetail groove 4, the structure of the structure of described trapezoidal sealing ring 3 and described dovetail groove 4 matches, the height of described trapezoidal sealing ring 3 is more than the degree of depth of described dovetail groove 4, described trapezoidal sealing ring 3 stretches out the part of dovetail groove 4 and fits tightly with described end door flange 2, it is 3mm that described trapezoidal sealing ring 3 stretches out the distance D of dovetail groove 4 part.
This utility model is got on the bus at the shell flange 1 of vacuum belt drier and is milled out dovetail groove 4, trapezoidal sealing ring 3 highlights trapezoidal profile consistent with shell flange 1 place dovetail groove 4, strictly controls the shell flange 1 gap with end door flange 2 well, is generally 3mm. Excesssive gap, sealing strip lacks compression stroke, it is easy to damage; Gap is too small, seals and is affected by machining accuracy, poorly sealed. Trapezoidal sealing ring 3 is done into strips, after embedding the dovetail groove 4 of shell flange 1, adopts oblique angle bonding, angle 30 degree, it is prevented that junction point is poorly sealed.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in scope of patent protection of the present utility model.
