Further, said slide construction comprises the bolt that is installed on sealing retainer bottom and is located at the snap ring on the sealing retainer inner ring surface, and said bolt end is with the roller bolt that the lower surface with the lower seal lip offsets; Said lower seal lip outer is provided with the locating notch that matches with snap ring.
Further, said locking mechanism comprises and is distributed in the some latch segments on the sealing retainer inner ring surface and is distributed in the sealing lip outer and the latch segment corresponding some latches that interlock; The flat face that the lower surface of said latch segment along the circumferential direction is divided into the inclined plane that guides usefulness and is used to compress latch.Utilize the inclined-plane to come channeling conduct, make the locking of latch and latch segment or release more smooth and easy.
Further, the angle of inclination on said inclined plane is 3 °～6 °.
Further, described upward sealing lip and lower seal lip are ring flange.
Further, said seal is a silicon rubber loop.
Further, said power set are cylinder.
The beneficial effect of the utility model: the utility model adopts power set to promote to seal retainer and rotates; Locking or release through locking mechanism come corresponding realize the airtight of bell and unlatching; Need not manually-operated during this time, thereby improve the automaticity and the security performance of product; The sealing property of body of heater also further improves.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of steam oxidation shaft furnace;
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the enlarged drawing at A place among Fig. 1;
Fig. 4 is the released state sketch map of locking mechanism.
The specific embodiment
With reference to Fig. 1-3; The utility model is a kind of hermetically-sealed construction of steam oxidation shaft furnace; The bell 1 that comprises retort 2 and be used to seal retort 2, bell 1 edge is provided with sealing lip 11, and retort 2 tops are provided with the lower seal lip 21 corresponding with last sealing lip 11; Be provided with seal 4 between last sealing lip 11 and the lower seal lip 21, also comprise through slide construction being installed on lower seal lip 21 outers and the sealing retainer 3 that can on this outer, rotate, promoting the power set 5 that sealing retainer 3 rotates; Be provided with the locking mechanism that sealing lip 11 and lower seal lip 21 are compressed in opposite directions between sealing retainer 3 and the last sealing lip 11, said locking mechanism triggers locking or release by the rotation of sealing retainer 3.
Slide construction comprises the bolt 31 that is installed on sealing retainer 3 bottoms and is located at the snap ring 33 on sealing retainer 3 inner ring surfaces, and said bolt 31 ends are with the roller bolt 32 that the lower surface with lower seal lip 21 offsets; Said lower seal lip 21 outers are provided with the locating notch 211 that matches with snap ring 33.
With reference to Fig. 4, locking mechanism comprises and is distributed in the some latch segments 30 on sealing retainer 3 inner ring surfaces and is distributed in sealing lip 11 outers and the latch segment 30 corresponding some latches 12 that interlock; The flat face 302 that the lower surface of said latch segment 30 along the circumferential direction is divided into the inclined plane 301 that guides usefulness and is used to compress latch 12.Utilize the inclined-plane to come channeling conduct, make latch 12 more smooth and easy with the locking or the release of latch segment 30, wherein the angle of inclination on inclined plane 301 is 3 °～6 °, preferably 4 °.
Above-mentioned last sealing lip 11 generally all adopts ring flange with lower seal lip 21, and seal 4 is a silicon rubber loop, and power set 5 are cylinder.
