Beneficial effect do: solve drug manufacturing enterprise wash thoroughly vacuum drying oven door sealing position, the sealed effect of vacuum drying oven is poor, the yielding difficult problem of sealing strip.
Description
Technical field
This utility model is related to vacuum drying oven apparatus field, more particularly to a kind of vacuum drying door sealing device.
Background technology
Vacuum drying oven is widely used in biochemistry, chemical pharmaceutical, health care, agri-scientific research, environmental conservation etc. and grinds
Study carefully application, can as powder be dried, bake and bank up with earth and all kinds of glass container sterilization and sterilizing use, it must reach necessarily
Sealing effectiveness, just can meet the requirement of CGMP GMP standard.Sealing strip is compressed in vacuum drying oven
Body and drying box door play sealing effectiveness, but the sealing structure common problem of vacuum drying chamber door is in the market：
Vacuum drying oven door weather strip mounting groove splices for right angle, no arc transition, there is cleaning in the piece junction of sealing strip dead
Angle, it is impossible to thoroughly cleaning, forms cross-contamination source；Sealing strip on vacuum drying chamber door is hollow mushroom-shaped structure, and vacuum
Drying box door sealing strip sealing structure seals for plane formula, and due to the pressured tight holding sealing of plane formula seal form, oven door is close
Strip of paper used for sealing is arranged on casing for hollow mushroom-shaped structure, between sealing strip and door, the pressurized rear formation contact with face for the face, and vacuum is done
, under same pressure, sealing strip is bigger with door contact area, and the pressure that sealing surface is subject to is less, and sealing effectiveness is got over for dry chamber door
Difference；Hollow mushroom configuration sealing strip is heated for a long time, use under pressurized environment, be easily deformed cause sealing effectiveness difference it is impossible to
Play complete obturation effect；Disadvantages described above leads to current vacuum drying oven cannot comply fully with CGMP
The requirement of GMP standard.
Content of the invention
For solving above-mentioned technical problem, this utility model provides a kind of vacuum drying door sealing device, solves medicine
Manufacturing enterprise to the cleaning of vacuum drying oven door sealing position thoroughly and the yielding difficult problem of sealing strip so as to sealing effectiveness more
Good.
The technical solution adopted in the utility model is：A kind of vacuum drying door sealing device, including casing with located at case
The chamber door of body inlet side, is provided with a circle seal groove, is provided with sealing strip in described seal groove around described tank inlet, described case
The upper/lower terminal of door is respectively equipped with locking handwheel, and the bottom of described sealing strip is embedded in described seal groove, described sealing strip
Front end highlights in described seal groove outside and V-shaped groove structure, and described chamber door compresses described sealing strip and by described locking
Handwheel is sealed with described casing.
The one side of described tank inlet is provided with the seal groove around described entrance one circle, is embedded in described seal groove
Sealing strip front end be V-type groove structure, V-type groove structure protrude outside seal groove, when chamber door is closed, rotational lock handwheel and
Casing is sealed, and chamber door compresses sealing strip, the pressurized formation contact with face for the line between sealing strip and chamber door medial surface；Because vacuum is done
, under same pressure, sealing strip is less with door contact area, and the pressure that sealing surface is subject to is bigger, and sealing effectiveness is got over for dry chamber door
Good, meanwhile, sealing strip is heated for a long time, under pressurized environment, and due to little with chamber door contact surface, sealing strip V-type groove is to both sides
Dispersive pressure, is unlikely to deform, and can keep good sealing effectiveness, decreases the number of times changing sealing strip.
Improve further, described seal groove is square, the chamfering of described seal groove is arc-shaped structure；In sealing strip
Piece junction is that circular arc is excessive, there is not cleaning dead angle, can improve cleaning efficiency to sealing strip thoroughly cleaning, reduce clear
Wash the time.
Improve further, also include cleaning pad, described cleaning pad is connected with described sealing strip V-type groove fit.
Improve further, described cleaning pad includes connecting portion and extension, described connecting portion embeds and is arranged on described sealing
In bar V-type groove, described connecting portion top be respectively equipped with to described sealing strip V-type groove both sides extend extension it is preferred that
The width of described cleaning pad is slightly larger than the width of sealing strip, and described extension is extended outside sealing strip two.
It is both needed to be carried out due to after each vacuum drying oven completion of processing, and the cleaning of the V-type groove of sealing strip is number
Tired, increase cleaning personnel labor intensity and scavenging period, described cleaning pad embeds in the V-type groove being arranged on described sealing strip,
After vacuum drying oven practicality is finished, finger catches the extension of cleaning pad to be pulled outwardly, and cleaning pad is taken off from sealing strip,
Change a clean cleaning pad, it is to avoid the cleaning of sealing strip V-type groove.
Described in the utility model have the beneficial effect that：Solve pharmaceutical producing enterprise clear to vacuum drying oven door sealing position
Wash not thoroughly, vacuum drying oven sealing effectiveness poor, the yielding difficult problem of sealing strip, improve cleaning efficiency, reduction operator's labor
Fatigue resistance, enables vacuum drying oven to comply fully with the requirement of GMP specification, is that the healthy cause of the mankind makes certain contribution.
