Abstract
The utility model relates to a chamber door hinge preloading device of a freeze-dryer, comprising a pivot connected with a freeze-dryer door body and a fixed hinge seat connected with a freeze-dryer chamber body, wherein the fixed hinge seat is in a hollow structure, and the internal part of the fixed hinge is provided with an adjusting block which is sheathed on a convex column in the fixed hinge seat; and a compression spring is arranged between the adjusting block and the convex column. The chamber door hinge preloading device of a freeze-dryer aims at improving the sealing structure of the freeze-dryer, and can improve the sealing effect when the freeze-dryer door body is closed on the basis of not changing the original sealing ring.
Description
Technical field
The utility model relates to a kind of sealing device of freeze dryer hermatic door, is a kind of large-scale freeze dryer chamber door hinge pre-tightening apparatus specifically.
Background technology
Generally, freeze dryer chamber door sealing ring needs to reserve the 10-15% decrement under the effect of external pressure.Can not contact with sealing ring is fine when the freeze dryer chamber door is closed during normal pressure, the moisture content when causing product pre-freeze in the air outside condenses in the flaggy surface, influences the freeze-drying of product.
And existing sealing device all is from the improvement of starting with of the structure and material of sealing ring, wish to improve the effect of sealing, but in fact along with the aging of sealing ring and selection material have certain life-span, be difficult to accomplish the maintenance sealing of long period, and the material material of raising sealing ring, the sealing ring of perhaps being diligent in more renewing all can improve cost of production, can't tackle the problem at its root.
Summary of the invention
The purpose of this utility model is to provide a kind of freeze dryer hermetically-sealed construction, can improve the sealing effectiveness of freeze-drying gate body when closing on the basis that does not change original sealing ring preferably.
The utility model is achieved by the following technical solution:
A kind of freeze dryer chamber door hinge pre-tightening apparatus, described freeze dryer chamber door hinge pre-tightening apparatus comprises the pivot that is connected with the door body, the fixed hinge seat that is connected with the freeze dryer casing, described fixed hinge seat is a hollow structure, its inside is provided with the adjustment piece, the side of described adjustment piece and pivotally connected, be provided with projection in the fixed hinge seat, described adjustment piece is socketed on the interior projection of fixed hinge seat, is provided with the compression spring between adjustment piece and projection.
The side of fixed hinge seat has the pivot locating hole, and the diameter of described locating hole is bigger than the diameter of pivot, and described being pivotally mounted in the pivot locating hole also is with sealing ring on the pivot.
The other end of described pivot gos deep in the door body, and is fixedly mounted on the body.
Described freeze-drying gate body is square door body, and described freeze dryer chamber door hinge pre-tightening apparatus is arranged on the edge of freeze-drying gate body, and described freeze dryer chamber door hinge pre-tightening apparatus is provided with the position with hingen can be identical or different.
Described adjustment piece is arranged on fixed hinge seat inside, and described adjustment piece can slide by single direction in the fixed hinge seat.
Described compression spring is an impaction state, also is provided with a body sealing ring on the freeze dryer doorframe, and the direction of the thrust that described door body sealing ring opposite house body applies is opposite with the elastic force direction of compression spring.
Described door body sealing ring is along doorframe arranged outside one circle, and described freeze dryer chamber door hinge pre-tightening apparatus is provided with a plurality of on freeze-drying gate body.
Excellent results of the present utility model is:
Employing is slidably adjusted piece and is improved the poorly sealed problem of body when closing.It is simple in structure, can provide moderate degree of pressure to realize that Men Tiyu is arranged on door the compressing of body sealing ring on the doorframe.Adopt the spring can keep-uping pressure of long period and do not need to change parts, if in use freeze dryer chamber door hinge pre-tightening apparatus goes wrong, can change one of them hinge pre-tightening apparatus separately also can change by a plurality of hinge pre-tightening apparatus together, and do not need integral replacing door body sealing ring, reduced the sealed precision of Men Tiyu doorframe simultaneously.
