Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram for the stirring axle envelope that laboratory air participates in reaction unit.
In figure：Shell 1, shaft 2, sleeve 3, stationary seal ring 4, moving sealing ring 5, annular fixed disk 6, protection cylinder 7, cover 8,
Blast pipe 9, discharge pipe 10, fastening screw 11.
Specific implementation mode
As shown in Figure 1, a kind of laboratory air participates in the stirring axle envelope of reaction unit, it is set between shell 1 and shaft 2,
Sleeve 3, stationary seal ring 4 and moving sealing ring 5 are respectively included, the bottom end of middle sleeve 3 is fixedly connected with shell 1, moving sealing ring 5
Be sheathed in shaft 2, stationary seal ring 4 is sheathed on the top of the vertical lateral wall of sleeve 3, and the top of stationary seal ring 4 with it is close
The bottom end of envelope rotating ring 5 fits closely, while the lower part of the vertical lateral wall in sleeve 3 is additionally provided with external screw thread, in the outer spiral shell of sleeve 3
Also screw-thread fit has annular fixed disk 6 on line；
It is also covered with protection cylinder 7 in the outside of stationary seal ring 4 and moving sealing ring 5, between the bottom end and shell 1 of protection cylinder 7
To be detachably connected, it is additionally provided with cover 8 on the top of protection cylinder 7, while being further opened with for across shaft at the center of cover 8
2 round cover mouth.
Under the above constitution, when shaft 2 is rotated during the work time, between stationary seal ring 4 and moving sealing ring 5 just
Phase mutual friction is will produce, and under prolonged mutually rubbing action, stationary seal ring 4 will generate abrasion with moving sealing ring 5, from
