Description
Technical field
The utility model relates to a kind of cigarette air channel vertical-type insertion plate door, specifically is used for the isolated door that thermal power plant deduster and air-introduced machine are imported and exported the cigarette ducting system, belongs to the mechanical seal structure technical field.
Background technology
At present, domestic most of power plant generally all uses venetian blind type to close the capital equipment that baffle door blocks as medium in the inherent cigarette air channel, but owing to operating mode in the cigarette air channel is special, dust-laden is big in the medium, there are chemical analysis such as sulphur simultaneously, cause wearing and tearing, corrosion etc. easily; And along with the continuous increase of unit, the flue size significantly increases, this all brings to a certain degree influence to intensity of door-plate etc., therefore under this occasion, use venetian blind type to close door and shown certain drawback especially, it shows that mainly sealing effectiveness is poor under the complete shut-down state, and flue resistance is big, the door-plate span is big, phenomenons such as being worn appears in easy deformation, door-plate easily, corrosion.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of cigarette air channel vertical-type insertion plate door is provided, and this insertion plate door intensity height opens and closes flexibly, can not deform, bad phenomenon such as clamping stagnation, and good sealing effect does not have and leaks outside and interior leakage long service life.
According to the technical scheme that the utility model provides, cigarette air channel vertical-type insertion plate door comprises framework, door-plate, and feature is: also comprise main shaft, electric operator, shaft coupling, double strand chain, transmission device and sealing device; Described electric operator is connected with main shaft by shaft coupling, and two cover double strand chains are fixed on the door-plate both sides; Transmission device comprises drive sprocket, driven sprocket, driven shaft, tensioning apparatus, and described driven sprocket is fixed on the driven shaft, and the driven shaft two ends are connected with tensioning apparatus, and drive sprocket is fixed on the main shaft, and sealing device is installed on the composition surface of door-plate and framework.
Be provided with the door-plate guide groove around the described framework.Described framework upper is diagonal brace fixedly.
The defence cover is installed in described main shaft both sides.Described doorframe is provided with the support roller of door-plate.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Easy for installation, can directly be connected by flange or welding with the cigarette air channel.Opening direction is for making progress, and about it and the space of below is unaffected.Operate simple and easy, on the spot, control far away, joint control etc. all make things convenient for.The intensity height opens and closes flexibly, can not deform, bad phenomenon such as clamping stagnation.Sealing system is reasonable, does not have to leak outside and interior leakage.Select materials rationally, service life of equipment is long.
