The utility model solves technical solution used by its technical problem and is also possible to:

The impeller-type flapper device, described in impeller body mainly by fixed ring I, fixed ring II, impeller blade, Impeller shafts, impeller hubcap and gasket composition, the impeller shafts are circular shaft, and circular shaft periphery is uniformly arranged six impellers Blade, impeller blade are arc, and one end of six impeller blades is separately connected impeller shafts outer circle, the other end of six impeller blades Two sides are separately connected fixed ring I and fixed ring II, and fixed ring I and fixed ring II are flat annular, the fixed ring I of flat annular and solid Determine to be respectively perpendicular six impeller blades of connection on the inside of ring II, is separately connected gasket, gasket on the outside of fixed ring I and fixed ring II It also is flat annular, gasket diameter is equal to fixed ring I or fixed ring II, and it is heavy that gasket, fixed ring I and fixed ring II pass through Head screw connection, impeller shafts both ends are separately connected two impeller hubcaps.

The utility model, which solves technical solution used by its technical problem, may also is that

The impeller-type flapper device, described in impeller blade be six, or be eight, or be ten.

The beneficial effects of the utility model are:

1, the utility model effectively buffers bulk falling material, and feeding inlet and discharge port are in partition shape always State achievees the purpose that lock gas, flue dust discharge caused by blocking material falls.

2, the conveying of the utility model material is smooth, solves conveyance conduit and generates that putty, manual cleaning is time-consuming and laborious asks Topic.

Specific embodiment

In Fig. 1-3, Fig. 4 Fig. 5, impeller-type flapper device, mainly by impeller protective shell 1, impeller body 2 and manhole cover 3 Composition, described in impeller protective shell 1 be it is rectangular, outside small arc-shaped is arranged in rectangular 1 middle part left housing wall of impeller protective shell, rectangular Outside orthodrome, the 2 outer circle radian one of radian and impeller body of small arc-shaped and orthodrome is arranged in the 1 right shell wall in middle part of impeller protective shell It causes, connecting flange is arranged in 1 both ends of impeller protective shell, and impeller body 2 is connected inside impeller protective shell 1, and impeller body 2 is circle, impeller 1 middle part side of protective shell is provided with square hole, connects manhole cover 3 outside square hole.

In Fig. 6 Fig. 7 Fig. 9, the impeller-type flapper device, described in impeller body 2 mainly by fixed ring I 21, solid Determine ring II 22, impeller blade 23, impeller shafts 24, impeller hubcap 25 and gasket 26 to form, the impeller shafts 24 are circle Axis, circular shaft periphery are uniformly arranged six impeller blades 23, and impeller blade 23 is arc, one end difference of six impeller blades 23 24 outer circle of impeller shafts is connected, the other end two sides of six impeller blades 23 are separately connected fixed ring I 21 and fixed ring II 22, fixed Ring I 21 and fixed ring II 22 are flat annular, and the fixed ring I 21 of flat annular and II 22 inside of fixed ring are respectively perpendicular connection six Impeller blade 23, fixed ring I 21 and II 22 outside of fixed ring are separately connected gasket 26, and gasket 26 is also flat annular, sealing It pads 26 diameters and is equal to fixed ring I 21 or fixed ring II 22, gasket 26, fixed ring I 21 and fixed ring II 22 pass through countersunk head Screw connection, 24 both ends of impeller shafts are separately connected two impeller hubcaps 25.
