Description
Technical field
The present invention relates to one kind rotation door switch unit, more particularly to a kind of pair of hinge lifting rotation door switch unit.
Background technology
Large epoxy ethane sterilizer is for the last pass sterilized to medical device product during medicine equipment is produced
Button apparatus.Ethylene oxide sterilizer is under uniform temperature, pressure and damp condition, with certain density ethylene oxide gas pair
The equipment that the medicine equipment being sealed in sterilizing chamber carries out low temperature suffocating sterilization.The sterile medium ring that ethylene oxide sterilizer is used
Oxidative ethane gas is a kind of very effective low temperature sterilization agent, is at home and abroad widely used.But oxirane is again one
Plant hypertoxic, inflammable, explosive chemical substance, it is desirable to can not be leaked in sterilization process.Therefore it is required that ethylene oxide sterilizer must
There are enough intensity, good sealing, easy for operation and good security.
Large-scale sterilizing device refer to sterilizer sterilizing chamber volume more than 1 cubic metre, the sterilizer of current largest domestic has reached
100 cubic metres.Sterilizing chamber is typically made up of the feeding gate and discharge door at casing and two ends.The door body at two ends be it is switchable, when
When needing sterilizing, feeding gate is opened, it would be desirable to which the medicine equipment of sterilizing incases in vivo, be then shut off feeding gate and gone out
Bacterium.After the completion of sterilizing works, discharge door is opened, again close discharge door after sterilized medicine equipment is released, be next
Individual sterilization cycle is prepared.Therefore door body is the important component of ethylene oxide sterilizer.Sterilizer mainly will to door body
Seeking Truth：There are enough strength and stiffness, the pressure that the malleation and negative pressure of the repeated action in casing cause can be born, do not produce
Crackle and obvious plastic deformation.Can not all be leaked by malleation and negative pressure in casing, door body switching manipulation is convenient, safe and reliable.
The switching device of door body has a great impact to meeting functional requirement of the sterilizer to door body, door body switching device
Function even badly influences the performance of sterilizer.In the prior art, the conventional door body switch side of large epoxy ethane sterilizer
Formula has two kinds, and one kind is translation door, and another kind is single hinge revolving door.
The door body of translation door is welded on what is constituted on smooth door-plate again by the framework that rectangular tube is welded, door body top peace
Equipped with two rollers, door body is hung on the guide rail being fixed on above doorframe by roller, promote door body to be put down to side from cylinder
The mobile mode of row realizes the switch of door body.Because the width of translation door and the width of casing are of substantially equal, door body is needed during enabling
Move to the side of sterilizer, it is therefore desirable to occupy with the much the same ground width of casing, this causes the utilization rate of factory building not
Height, capital expenditure is excessive.
The door body of single hinge revolving door is also that the frame welding being welded into by rectangular tube is constituted on smooth door-plate, doorframe
Side is connected firmly with the switching device of one group of list hinge revolving door.The side of door body also fills with the single hinge rotation door switch of this group
Put connection.Single hinge switching device is made up of three parts, is fixed on the door-hinge fixed seat (having two axis holes) of doorframe side, Gu
The door body fixed seat (having an axis hole) of door body side is scheduled on, two the three of fixed seat holes are connected with an axle turn into
One hinge axis, enables door body around hinge axle to rotate, and single hinge revolving door also has obvious shortcoming：When casing receives malleation, door-hinge
The half of whole pressure will be born.So door-hinge and corresponding parts (axle, set, bolt, backing plate, fixed plate etc.) are all necessary
Mutually should bear very big power.When casing basal area is smaller smaller with tank pressure, door-hinge component makees corresponding reinforcement can also be held
Receive, when casing basal area is larger or during pressure higher, to bear the pressure of tens tons of casing, door shaft structure will be designed to very huge
Greatly, such structure is inadvisable.Therefore single hinge revolving door sterilizer is typically only applicable to that casing basal area is smaller or casing pressure
Power it is smaller (<Used under conditions of 0.03MPa).
With the development of national healthcare hygiene industry, the demand to sterilization of medical instrument equipment is increasing, particularly
Demand to normal pressure sterilizer large-scale, higher becomes apparent.The volume of large-scale sterilizing device is vertical via original larger 20
Square rice develops into 100 cubic metres, and cross dimensions develops into bigger 2200 × 2800 by original 1350 × 2000 larger (mm)
(mm).Tank pressure demand malleation increases to 0.10MPa by original general 0.03MPa, therefore mesh first two door-opening mode goes out

With when opening the door conversely, at closing time door body first after the opposite direction of door body door-hinge 23 rotation one minute angle 2 α spacer pin with
The sidewall contact of spacing hole, door body stops with the relative rotation of contiguous block, and door body drives contiguous block to cause around door when being rotated further
Frame door-hinge 21 rotates.When door body touches doorframe away from one side of door-hinge, if firmly larger at closing time, the used of door body is added
Property, the opposite side of possible door body is also adjacent to doorframe, at this moment cylinder exhaust, and door body smoothly can be fallen on gate stop down.If closed
Exerted oneself during door smaller, the inertia of door body is also smaller, behind the side of door body and door frame contact, the opposite side of door body is (near door-hinge one
Side) may be with the gap c of doorframe formation, it is impossible to it is adjacent to doorframe.But have determined that spacer pin with spacing hole during due to design
The δ of gap 2, it is ensured that less than original door body and the maximum clearance of doorframe, this can guarantee that door body when declining not by gate stop card to gap c
Firmly.The effect of double hinges is to ensure that the relative doorframe of door body energy is moved in parallel, and the effect of spacer pin is to limit door body translational movement not
More than prespecified numerical value.
