By adopting technique scheme, L shaped seal is fixed by fixed part and baffle plate, when fitting gradually on the inclined-plane of two baffle plates, pushed and bending to the inside by inclined-plane sealing, the end of the sealing of latter two seal is stuck in the annular seal space that forms parallelogram on the inclined-plane of another block face, the sulfur-containing smoke gas of both sides only can make the sealing of seal tightr with coordinating of inclined-plane in the time of squeeze sealing member like this, seal tightlyer, avoid the leakage of sulfur-containing smoke gas.
The utility model is further set to: described sealing tilts to the other end of fixing baffle plate.
By adopting technique scheme, sealing tilts to guarantee that to the other end of fixing baffle plate inclined-plane can, smoothly by sealing bending to the inside, guarantee the formation of annular seal space when the crush seal portion, guarantees sealing property.
The utility model is further set to: described driving shaft extends to doorframe outside and end is fixedly installed linkage block, two described linkage block relative drive shafts radially two ends respectively correspondence be provided with extension, the hinged gangbar that is provided with between described corresponding extension.
By adopting technique scheme, linkage block coordinates gangbar to guarantee the synchronized movement of two baffle plates, and secondly same drive source can drive two drive shaft turns simultaneously.
The utility model is further set to: the relative baffle plate of described linkage block be arranged in parallel, between two described linkage blocks, between the extension of a pair of non-correspondence, is provided with back-moving spring.
By adopting technique scheme, back-moving spring is set and guarantees that two baffle plates are further tight in the time of closure, guarantee that sulfur-containing smoke gas can not pass between two baffle plates.
The utility model is further set to: one end that described linkage block is not provided with back-moving spring is provided with the driving cylinder that promotes linkage block rotation.
By adopting technique scheme, drive cylinder to guarantee that the switching of baffle plate is relatively rapid, the driving force providing is larger, and back-moving spring can overcome and drives cylinder to stop the sealing that the certain axial displacement of exhaust hood axle brings not tight.
The utility model is further set to: described doorframe is positioned at the extended position of driving shaft and is fixedly installed the first rolling bearing pedestal that is sheathed on driving shaft, described doorframe outside is also provided with U-shaped bearing bracket stand, described U-shaped bearing bracket stand comprises both sides and the fixing support of doorframe and the platform at middle part, is fixedly installed the second rolling bearing pedestal that is sheathed on driving shaft on described platform.
By adopting technique scheme, two rolling bearings have guaranteed the rotational stability of driving shaft to greatest extent, before comparing, a bearing are only set and cannot meet the situation that load is larger.
The utility model is further set to: the cross section of described baffle plate is the diamond shaped centered by driving shaft.
Secondly by adopting technique scheme, being arranged to diamond shaped can all use four of a baffle plate face as inclined-plane, make its service life higher, and diamond shaped had both guaranteed and the stability maintenance of driving shaft, also guarantees most the simplifying of weight of baffle plate, saves the energy.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
