Abstract
The utility model discloses a novel drying box conduction oil header sealing structure which is characterized in that the sealing structure comprises a vacuum box body, a conduction oil header and a separation plate, a heat preservation layer is arranged outside the vacuum box body, the conduction oil header penetrates through and is fixed on the heat preservation layer through a sealing device, and the sealing device is composed of a vacuum sealing flange arranged on the inner side of the heat preservation layer and an oil seal flange arranged on the outer side of the heat preservation layer. Compared with the prior art, the novel drying box conduction oil header sealing structure has the advantages that when a sealing ring of the vacuum sealing flange in the box body is replaced, a new sealing ring just needs to be arranged on the outer side of a vacuum drying body in a sleeved mode to replace the sealing ring, and any conduction oil can not leak to the inner side of the box body; when a sealing ring of an oil seal is replaced, operation is carried out outside the vacuum drying box completely, and the inside of the box body can not be polluted; when the separation plate needs to be moved out of the drying box, mounting and dismounting of the flanges is convenient.
Description
Technical field
The utility model relates to conduction oil collector in a kind of drying box of pharmaceutical industry freeze dryer and the syndeton of vacuum chamber, relates in particular to a kind of Novel drying box conduction oil collector hermetically-sealed construction.
Background technology
Freeze dryer full name be vacuum freeze drier, be the principle of utilizing distillation by first freezing then vacuumizing and make the equipment of moisture drying of liquid.There is the dividing plate of a set of hollow its vacuum drying casing inside, this dividing plate energy loading stocks and it is carried out to freezing and heat drying.Whole drying box inside is full of vacuum.Collector is that dividing plate external member is connected with vacuum chamber, and this connection can be welded or flange connects.
At present, the problem that freeze dryer industry faces is the problem of the maintenance of dividing plate external member, if welded, when safeguarding, need to after by collector cutting, just can be shifted out so, then safeguards.
In addition, if adopt a flange to connect at box house, the risk that there will be conduction oil to reveal in the process of dismounting so, particularly in equipment running process, once conduction oil enters into vacuum chamber, due to the sharply effect of diffusion in vacuum chamber inside, can cause the pollution of product so, particularly, in the production process of the ejection preparation of pharmacy, such leakage is fatal.
Summary of the invention
The utility model, in order to solve the above-mentioned deficiency of prior art, provides a kind of Novel drying box conduction oil collector hermetically-sealed construction.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of Novel drying box conduction oil collector hermetically-sealed construction, it is characterized in that: comprise vacuum chamber, conduction oil collector and dividing plate, described vacuum chamber outside is provided with heat-insulation layer, described conduction oil collector is passed and is fixed on by sealing device on heat-insulation layer, and described sealing device consists of with the oil sealing flange that is arranged at heat-insulation layer outside the vacuum seal flange that is arranged at heat-insulation layer inner side.
The utility model advantage is compared with prior art: when changing the sealing ring of vacuum seal flange of box house, only need to be inserted in sealing ring from the outside of vacuum drying body, and replaceable, without any conduction oil, be leaked to the risk of box inside; When changing the sealing ring of oil sealing, in the outside of vacuum drying chamber, operate completely, can not produce the pollution risk to box house; In the time of dividing plate external member need being shifted out to drying box, the dismounting of flange can be convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation at A place in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of Novel drying box conduction oil collector hermetically-sealed construction, it is characterized in that: comprise vacuum chamber 1, conduction oil collector 2 and dividing plate 3, described vacuum chamber 1 outside is provided with heat-insulation layer 4, described conduction oil collector 2 passes and is fixed on heat-insulation layer 4 by sealing device 5, and described sealing device 5 consists of with the oil sealing flange 52 that is arranged at heat-insulation layer 4 outsides the vacuum seal flange 51 that is arranged at heat-insulation layer 4 inner sides.
The above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as any being equal to done according to spirit that this patent discloses changes or modify, all fall into the scope that this patent comprises.
