The rectangle impeller of shutter adopts the single-store frame formula, and baffle door is in off position the time, the plane of each impeller not at grade, but layout in wave shape.Rotating shaft the rotating torque effect under, the contact-making surface mutual extrusion of adjacent impeller length direction plays sealing effectiveness.The hollow sealing bar that the seal of impeller periphery constitutes for the hollow elastic composite, inside is full of fluid media (medium).When the seal mutual extrusion of length direction between the baffle door impeller (along rotor shaft direction) is out of shape, form sealing at length direction on the one hand, on the other hand, can force the fluid media (medium) in the seal to flow to the impeller width, force the seal of width to expand, with baffle door frame inner surface jam-packed, reach the purpose of impeller width sealing.
Operation principle of the present invention and process are: each impeller provides rotating torque by pneumatic or electric operator.Guarantee the direction of rotation of any adjacent impeller by the appropriate design jointed gear unit, corner is harmonious mutually.When sealing state, each impeller layout in wave shape, mutual jam-packed between the impeller forms sealing between adjacent impeller contact-making surface, and forces the seal of impeller width to expand, and forms to seal between impeller and doorframe.When baffle door was opened, adjacent impeller counter-rotation broke away from the extruding contact, and the dilatancy of width returns to normal, and makes impeller broadside and doorframe also disengage automatically, and along with being rotated further of impeller axle, baffle door is opened gradually.
Beneficial effect: the invention has the beneficial effects as follows
1. saved supply, the control system of intermediate medium, stopped, fundamentally guaranteed the safe and reliable of sealing, also saved cost simultaneously because of the undesired failure of apparatus that causes of intermediate medium system works.
2. impeller is a single-store frame formula structure, and simpler than double panel structure, rigidity is better, and advantage is more obvious when being applicable to the large scale baffle door.
3. each impeller layout in wave shape during sealing state, the sealing surface of adjacent impeller holds out against mutually, and according to the amplification of wedge structure to power, less rotating shaft moment can produce bigger thrust on sealing surface.Adopt soft contact-making surface to compress when sealing thrust deficiency often thereby solved large-scale baffle door, be difficult to satisfy the problem of seal pressure.
4. seal adopts the elastomeric material of inner filling fluid media (medium), utilizes the extruding on the long limit of impeller to force the seal expansion of broadside to form the sealing of broadside and doorframe inner surface.Fundamentally eliminate the friction between impeller broadside and the doorframe sealing surface, helped reducing driving moment, improved the service life of sealing surface, avoided stuck phenomenon.
