Seal casinghousing front end is arranged in contracting driving device, and the retractable driving device includes one and extends in seal casinghousing and be directed toward flange
The telescopic rod of disk, the valve body setting are provided with insertion cylinder corresponding with ring flange inner hole on telescopic rod end, the valve body,
The sealing ring being located in insertion cylinder outer circle is provided on the valve body, sealing ring front indent is provided with a circle V-shaped groove, institute
It states and is respectively arranged with chamfering on ring flange end outer circle and inner wall and forms Double-conical-surface corresponding with V-shaped groove.
Wherein, the retractable driving device is pneumatic cylinder.
Wherein, the insertion cylinder end welding is provided with cambered surface sealing plate corresponding with the blowing port of high mixer cylinder.
Wherein, embedded groove corresponding with sealing ring is arranged in indent on the valve body.
Wherein, the seal casinghousing bottom is provided with discharging pipe fitting.
Wherein, the seal casinghousing rear end is fixed by bolts with ring flange.
Wherein, the guide rail positioned at valve body two sides is horizontally arranged in the seal casinghousing, valve body two sides are longitudinal respectively
It is provided with the litter being located on guide rail.
The utility model has the beneficial effects that a kind of high mixer drain hole sealing structure, the biconical surface structure of ring flange end
Be conducive to drawing for powder to fall, it is not easy to sizing, and cooperated using the V-shaped groove on sealing ring with Double-conical-surface, it is ensured that sealing effect, group
Dress is convenient, flexible operation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlarged view of part A in Fig. 1.
Specific embodiment
The technical solution of the utility model is further illustrated below with reference to Fig. 1 to Fig. 2 and by specific embodiment.
A kind of high mixer drain hole sealing structure, comprising: high mixer cylinder 5, valve body 2, seal casinghousing 6 and flexible driving dress
3 are set, ring flange 1 is provided at the blowing port of the high mixer cylinder 5,6 rear end of seal casinghousing is connected with ring flange 1
It connects, 6 rear end of seal casinghousing is fixed by bolts with ring flange 1, mounts and dismounts more convenient, maintenance convenience.
6 front end of seal casinghousing is arranged in the retractable driving device 3, and the retractable driving device 3 extends to close including one
In capsule body 6 and be directed toward the telescopic rod of ring flange 1, the retractable driving device 3 is pneumatic cylinder, pneumatic cylinder using compressed air into
Row driving, is operated, flexibility is good using air valve.
The setting of valve body 2 is provided with insertion cylinder corresponding with 1 inner hole of ring flange on telescopic rod end, the valve body 2
10, insertion 10 end of the cylinder welding is provided with cambered surface sealing plate 11 corresponding with the blowing port of high mixer cylinder 5, avoids mixing
Powder when material enters insertion cylinder 10, also avoids powder and enters between insertion 10 outer circle of cylinder and 1 inner wall of ring flange, is promoted and blocked
Effect.
The sealing ring 4 being located in insertion 10 outer circle of cylinder is provided on the valve body 2, on the valve body 2 indent setting with it is close
The corresponding embedded groove of seal 4, installation convenience, can also be fixed using glue.The positive indent of the sealing ring 4 is provided with one
V-shaped groove is enclosed, chamfering is respectively arranged on the 1 end outer circle of ring flange and inner wall and forms Double-conical-surface 9 corresponding with V-shaped groove.
9 structure of Double-conical-surface is conducive to drawing for powder and falls, and reduces sealing surface sizing problem, and cooperate using V-shaped groove and Double-conical-surface 9, it is ensured that
