Abstract
The invention provides a hollow hinge of a box door. Two ends of the hollow hinge are respectively a box door connecting end for connecting the door box and a doorframe connecting end for connecting a doorframe; a hinge plate is arranged in the middle of the hollow hinge; the hinge plate is connected with the doorframe connecting end by a pin shaft; the hollow hinge is provided with a cavity which can run through an external part through a first opening and a second opening; the first opening is positioned at the doorframe connecting end; and the second opening is positioned on in the hinge plate or at the box door connecting end. By using the hollow hinge, fluid is introduced into and drawn forth of a fluid passage of the box door of a freeze dyer from a machine room behind the separating doorframe, the fluid passage is not separately arranged outside the hinge of the box door; and a fluid pipeline and the hinge of the box door are combined into one. By using the hollow hinge, not only can the difficulties of a conventional hose assembly and a rotating joint which are positioned between the box door of the freeze dryer and the separating doorframe on cleaning and sterilization working aspects be eliminated, but also the hidden danger that the fluid leaks to pollute a sterile room can be eliminated.
Description
Technical field
The present invention relates to a kind of hollow hinge of chamber door, it is suitable for adopting vacuum freeze-drying technique to carry out the dry freeze dryer that uses to medicine and pharmaceuticals industry adopts steam to carry out the sterilizing cabinet of sterilizing.
Background technology
Because described freeze dryer is identical with the principle that the employing steam of described sterilizing cabinet carries out sterilizing, and chamber door is similar to the structure of isolation doorframe, describes only for freeze dryer so following.
Freeze-drying for sterile preparation similar drug is produced, and for preventing medicine from being polluted by production equipment, needs regularly to carry out sterilization treatment to freeze dryer.Adopt superheated vapour, position or the system heating that freeze dryer may be polluted medicine also keep being no less than 30min to more than 121 DEG C, are the reliable methods being suitable for freeze dryer sterilizing.After freeze dryer sterilizing, if adopt the cooling means of natural heat dissipation, the cool time of equipment often needs 12 hours.In order to be produced by equipment investment as early as possible, pharmaceutical factory often needs the fluid adopting proper temperature, and the position be heated by steam freeze dryer or system carry out pressure cooling.Fluid can be gas, water or oils.The drying box of freeze dryer is one of position of steam sterilizing, in order to shorten the cool time of drying box, the casing of drying box and chamber door is provided with cooling jacket, for forcing cooling.
At present, between the chamber door and isolation doorframe of freeze dryer, fluid introduced from the machine room after isolation doorframe and draws the method for chamber door, generally adopting the method that pipeline is set separately.Chamber door due to freeze dryer needs often to open, and opening angle often needs to reach about 110 degree, simultaneously, chamber door is conducted oneself with dignity the sagging displacement of chamber door caused, also need regularly to adjust the installation site of box door hinges, so, in order to meet the displacement demand of chamber door, be separately set in the pipeline between chamber door and isolation doorframe, what generally adopt is connect swivel joint with hose, and then connect chamber door and the method for isolating doorframe, Fig. 1 illustrates isolation doorframe 1, chamber door 2, flexible pipe 3, swivel joint 4, hinge 5, door frame of box 6, the connection facilities of chamber door cover plate 7, wherein, isolation doorframe 1 is welded on door frame of box 6, chamber door cover plate 7 is arranged on chamber door 2, interface one end of swivel joint is connected with flexible pipe 3, the other end by pipe fitting with pass through the pipeline of isolating doorframe and be connected.As can be seen from Figure 1, fluid introduced from the machine room after isolation doorframe and draws the fluid passage of chamber door, being arranged on separately outside box door hinges.
With shown in Fig. 1 in order to fluid being introduced from the machine room of isolating after doorframe and drawing chamber door, and the box door hinges that the method arranging separately pipeline is corresponding, as shown in Fig. 2-1 and Fig. 2-2, containing the first hinge seat 8, first bearing pin 9, packing ring 10 between first hinge seat and carrier bar, adjustment screw 11, be arranged on the collar 12 on the first bearing pin, carrier bar 13, second hinge seat 14, second bearing pin 15, base bearing 16, the packing ring 17 arranged between carrier bar and bearing, back-up ring 18, dog screw 19 and the collar 20 be arranged on the second bearing pin, be mainly used in supporting chamber door and carry out opening and closing campaign, wherein, hinge seat 8 is installed on the chamber door 2 of freeze dryer, hinge seat 14 is installed on the door frame of box 6 of freeze dryer, carrier bar 13 and bearing pin 15 are solid construction.
By the pipeline that fluid is introduced from the machine room after isolation doorframe and drawn chamber door and arrange separately, in order to meet the displacement demand of freeze dryer case door, what adopt is that hose connects swivel joint and then connects chamber door and the method for isolating doorframe, because hose and swivel joint junction also exist structure gap, clean and the disinfection carried out this structure gap is very difficult, and there is the situation of the damaging leakage that flexural fatigue causes due to hose, the situation that the tiny leakage that swivel joint also exists sealing surface constantly accumulates, therefore, above-mentioned method fluid being arranged separately pipeline from the machine room introducing after isolation doorframe and extraction chamber door, not only there is difficulty that is clean and disinfection aspect, and there is the hidden danger polluting bacteria free room because fluid leaks.
Summary of the invention
For overcoming between the existing chamber door at freeze dryer and isolation doorframe, deficiency when chamber door is introduced and drawn to fluid from the machine room after isolation doorframe method, the present invention wants to provide between a kind of new chamber door at freeze dryer and isolation doorframe, is introduced by fluid and draw the device of chamber door from the machine room after isolation doorframe.
Device provided by the invention is a kind of hollow hinge of chamber door, two ends are chamber door link for connecting chamber door and the doorframe link for being connected doorframe respectively, centre is carrier bar, described carrier bar and described doorframe link are with pinned connection, this hollow hinge is provided with can by the cavity in the first opening and the through external world of the second opening, first opening is positioned on described doorframe link, and the second opening is positioned on carrier bar or on chamber door link.
