Embodiment:
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Shown in Fig. 1～5; A kind of nothing of isolator is leaked transfer device; Comprise isolator 1, be opened in the transferring cabin 2 on the isolator 1 and be used for the glove port (being fixed with gloves 20 on the glove port) that the confession staff of isolator built-in function is used and be installed in the staving 3 on the transferring cabin 2; In said transferring cabin 2, be provided with inside door 9, this transferring cabin 2 is circular, and is provided with the inside door sealing ring 13 of silica gel matter between inside door 9 and the transferring cabin 2; Through this inside door sealing ring 13 when inside door 9 is closed, guarantee and the doorframe of transferring cabin 2 between sealing, prevent that the dusty gas in the isolator 1 from leaking.Said isolator 1 is provided with lead-frame 18; Be provided with several bayonet sockets 17 in the said lead-frame 18, said staving 3 has bucket outer wall 15, on said bucket outer wall 15, is provided with the fixture block 16 that is clasped mutually with bayonet socket 17; In order to play the bung that prevents staving 3 and the wearing and tearing of fixture block 16; This lead-frame 18 is coated on the zipper tape place of staving 3, can certainly not adopt the form of lead-frame 18, and adopts other removable ways of connecting to connect transferring cabin 2 and staving 3.Be provided with sealing bucket sealing ring 18 between said isolator 1 and the staving 3.
Be provided with mobilizable bung 4 in the bung of said staving 3, the diameter of this bung 4 equates with inside door 9.Said bung 4 has anchor ring 5, is positioned at the medial surface 6 and the lateral surface 7 of anchor ring 5 both sides; Said staving 3 contacts with anchor ring 5, is provided with several snap rings 11 in said staving 3 inboards, on said anchor ring 5, is provided with the annular groove 12 with said snap ring 11 snap into engagement; Adopt this kind structure to make the cooperation of staving 3 and bung 4; Its objective is to prevent when staving 3 is carried out high-temperature sterilization, in case the separating of staving 3 and bung 4 and bung, also adopt this kind structure simultaneously for follow-up staving 3 both after being installed on the transferring cabin 2 can separate fast; Certainly also can adopt the shiny surface contact between staving 3 and the anchor ring 5; As long as after both cooperation is not to be easy to get loose, and be that leakage of air things and extraneous airs in the staving 3 do not get in the staving 3, between said staving 3 and bung 4, be provided with bung sealing ring 14 in order to play.
On the lateral surface 7 of said bung 4, be provided with indent teeth groove 8; Said indent teeth groove 8 is several and annular spaced set; Said inside door 9 is provided with the lobe 10 that matches with said indent teeth groove 8; And this lateral surface 7 fits tightly in the side of said inside door 9, thereby guarantees that isolator 1 internal contamination air can not pollute bung 4 and inside door 9 lateral surfaces.When staving 3 and isolator 1 installed and fixed together, the lobe 10 on the inside door 9 will fix this indent teeth groove 8.
Refer again to Fig. 1～3, said apparatus is divided into two parts before installing when concrete the use: have the isolator 1 and staving 3 of transferring cabin 2, isolator 1 upper internal door 9 is the long state that closes.When needs are given the feeding animal in the equipment; Staving 3 is aimed at this transferring cabin 2 to be installed; Promptly just staving 3 is docked in the lead-frame 18; Till dextrorotation goes to and can not rotate then (the bayonet socket 17 snap lock states on fixture block on the staving 3 16 and the isolator 1), and 10 this moments of lobe on the inside door 9 also since the indent teeth groove 8 on rotation and the bung 4 to engagement.Then through gloves stretch into for 20 mouthfuls hold inside door 9 handle 21 internally with inside door 9 direction rotation in the same way when installing just now; After rotating to a certain degree (annular groove 12 and the snap ring on the staving 3 11 on the bung 4 break away from); Can with bung 4 break away from staving 3 with inside door 9 outer drawing this moment; After bung 4 was raised, the staff just can glove port gets food in the staving 3 and feeds.Certainly, if be to adopt being connected of annular groove 12 and snap ring 11 between bung 4 and the staving 3, then need not, as long as outer drawing inside door 9 rotations.After feeding is intact, close upper internal door 9, be rotated counterclockwise simultaneously to bung 4 and staving 3 and mesh again, and then rotate counterclockwise staving 3, staving 3 is taken off from isolator 1, deliver to after packing at last and carry out sterilization in the high-pressure steam sterilizing pan.
