Abstract
The utility model provides a hollow hinge of a box door. Two ends of the hollow hinge are respectively a box door connecting end used for being connected with the box door and a door frame connecting end used for being connected with a door frame. The middle portion of the hinge is a hinge plate. The hinge plate and the door frame connecting end are connected through a pin shaft. A cavity capable of being communicated with the outer environment through a first opening and a second opening is formed in the hollow hinge. The first opening is located in the door frame connecting end and the second opening is located in the hinge plate or the box door connecting end. The hollow hinge of the box door is capable of leading fluid into or out of a fluid channel of the box door of a freeze dryer from the back side of a separation door frame. The hollow hinge is not arranged outside the box door independently and the fluid channel and the box door are combined as a whole. According to the hollow hinge of the box door, difficulties of cleaning, disinfection and the like of a hose component and a rotary joint which are placed between the box door of the freeze dryer and the separation door frame are eliminated and hidden danger of pollution of a bioclean room caused by fluid leakage is eliminated.
Description
Technical field
The utility model relates to a kind of hollow hinge of chamber door, and it is suitable for adopting vacuum freeze-drying technique to carry out to medicine the sterilizing cabinet that the dry freeze dryer that uses and pharmaceuticals industry adopt steam to sterilize.
Background technology
The principle of sterilizing due to the employing steam of described freeze dryer and described sterilizing cabinet is identical, and the structural similarity of chamber door and isolation doorframe, so following narration is only take freeze dryer as example.
For the freeze-drying production of sterile preparation similar drug, polluted by production equipment for preventing medicine, need regularly freeze dryer to be carried out sterilization treatment.Adopting superheated vapour, more than freeze dryer may be polluted the position of medicine or system heating to 121 ℃ and keep being no less than 30min, is the reliable method that is suitable for the freeze dryer sterilization.After the freeze dryer sterilization, if adopt the cooling means of natural heat dissipation, often need about 12 hours the cool time of equipment.With equipment investment production, the pharmaceutical factory often needs to adopt the fluid of proper temperature for as early as possible, and position or system that freeze dryer is heated by steam force 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, is provided with cooling jacket on the casing of drying box and chamber door, is used for forcing cooling.
At present, between the chamber door of freeze dryer and isolation doorframe, fluid is introduced and drawn the method for chamber door from the machine room of isolation doorframe back, generally adopt the method that pipeline is set separately.because the chamber door of freeze dryer need to often be opened, and opening angle often need reach about 110 degree, simultaneously, the sagging displacement of chamber door that the chamber door deadweight causes, also need the installation site of box door hinges is regularly adjusted, so, in order to satisfy the displacement demand of chamber door, be separately set in the pipeline between chamber door and isolation doorframe, what generally adopt is to connect swivel joint with hose, and then connection chamber door and the method for isolating doorframe, Fig. 1 has represented 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 is connected with the pipeline that passes through the isolation doorframe by pipe fitting.As can be seen from Figure 1, fluid is introduced and drawn the fluid passage of chamber door from the machine room of isolation doorframe back, be arranged on outside box door hinges separately.
