Description
The utility model relates to a kind of locking device, is specifically related to a kind of forced locking device that is used for freeze dryer.
Vacuum freeze drier is commonly called as freeze dryer, it is a kind of drying equipment that is widely used in medicine, food service industry, its purposes is to allow material freeze at low temperatures, and moisture is wherein distilled under vacuum state, and collects the moisture of condensation to reach the purpose of material drying and dehydrating with the method for condensation.At present, along with China's medicine, food service industry are further adapted to international practices, freeze dryer is also more and more higher in aspect instructions for uses such as vaccine, blood product, biological products, medicine, health products.
Vacuum freeze drier has drying box and water vessel with the parts that freeze dried substance directly or indirectly contacts, drying machine and water vessel contain various machine components all might become the place of sheltering evil people and countenance evil practices, in order to improve the quality of freeze-dried products, guarantee the healthy and safe of people's life, drying box and water vessel must carry out sterilization, and in the past drying box was mainly adopted the alcohol irrigation and disinfection, but it is relatively poor to carry out the sterilization effect in this way, because many dead angles are wherein arranged can't be touched at all, and water vessel is a semi-enclosed container, can't sterilize for it with alcohol at all.
As everyone knows, utilizing high temperature, high pressure that equipment is carried out sterilization is effective, the most thorough a kind of method, but freeze dryer is a kind of low temperature, low-voltage equipment, therefore have higher requirement for the manufacturing of drying box and water vessel, especially drying box is a rectangular pressure vessels, dry chamber door will often be opened, so the locking device of drying box should bear high temperature, high pressure (malleation) during steam sterilizing, bears low temperature, low pressure (negative pressure) again.
The locking device of early stage steam sterilizing freeze dryer adopts the traditional bolt locking method of pressure vessel, around the chamber door of drying box some bolts is installed exactly and is locked.Though this method reliability is better, it is convenient to make also religion, and the labor intensity of operating personnel religion is high, and bolt arrangement hides dirt easily, does not meet the requirement that GMP produces.
The purpose of this utility model is to provide a kind of novel forced locking device that is used for freeze dryer, and it can satisfy autoclaved needs, meets the requirement that GMP produces.
For this reason, the utility model provides a kind of forced locking device of freeze dryer, it is that a cylinder is installed on the doorframe of drying box, magnetic switch and door bolt are housed on this cylinder, behind the unlatching cylinder, make door bolt insert doorframe, when door bolt reaches prescribed stroke, magnetic switch sends Continuity signal, and drying box is locked fully, so just can guarantee the auto lock of drying box.
The utility model can be saved labor intensity of operating personnel greatly owing to can automatically lock drying box, and the sound construction of this locking device, can guarantee drying box safety, reliable when high temperature, autoclaving sterilization.
Below, with embodiment the utility model is further described in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the A portion profile of Fig. 1
As shown in Figure 1, the casing 1 and the box-frame 2 of the drying box of the forced locking device of a kind of freeze dryer that the utility model provides are structure as a whole, on box-frame 2, stud with silicone rubber O-ring 3, on box-frame 2, also have cylinder 5, be connected with casing 1 with chamber door bolt 7 before the steam sterilizing sterilization, open vavuum pump 16, make and produce negative pressure in the drying box 1, this moment, the chamber door 8 of drying box closely contacted with silicone rubber O-ring 3, and silicone rubber O-ring 3 is compressed, and makes it to produce certain deformation drying box is sealed fully.
Then, open cylinder 5, as shown in Figure 2, door bolt 4 and magnetic switch 12 that extended cylinder is arranged on the cylinder 5 that the utility model provides, when cylinder 5 pistons moved, its door bolt that stretches out 4 can insert the recess 13 of drying box chamber door 8, and same displacement takes place magnetisable material on these cylinder 5 piston rods, when magnetisable material arrived prescribed stroke, magnetic switch 12 closures were sent Continuity signal.Cylinder on the drying box can have several, can decide according to the size of drying box, when all magnetic switch all send Continuity signal, steam valve 10 is opened, and steam enters drying box, makes the pressure in the casing 1 reach 0.11MPa, at this moment, the chamber door 8 of drying box is stressed to extrapolation.
The chamber door 8 and the base plate 18 of this drying box weld together, and the chamber door 8 stressed ambassador's doorframes 2 that add gradually of drying box contact with door bolt 4, the chamber door 8 of drying box can't outwards be moved, thereby reach the effect of sealing.During moise-heat sterilization, the chamber door 8 of drying box will bear the pressure of 0.11Mpa, and these chamber door 8 usefulness channel-section steels 15 are reinforced.Then, in the loss of heat in the drying box when preventing of the heat-insulating material 14 of spreading operating temperature-57 ℃～+ 125 ℃ on the chamber door 8 in cooling or heating.
The drying box skin that the utility model provides is equipped with stainless steel decorated sheet 6, and its effect is in machine room part and clean room's part is isolated separates drying box.On cylinder 5, also be added with sealing gasket 11, be used for preventing steam-cylinder piston motion and cause dirty air to enter casing 1.
The forced locking device of the freeze dryer that the utility model provides is a kind of pressure vessel, therefore when carrying out high temperature, autoclave sterilization, must guarantee safety, for example under situation about take place having a power failure, above-mentioned cylinder must self-locking, makes door bolt still be fixed on original position and can not withdraw.
