Description
Technical field
The utility model is related to a kind of sealed door.Specifically, it is that the coal dust for grinding flour mill sends into the outstanding of boiler furnace
Hanging hot air disperser, it is adaptable to which thermal power plant is boiler coal supply.
Background technology
Both known about in thermal power industry, be equipped with, by Coal dressing into the flour mill of coal dust, being set on Coal-disintegrating machine on boiler
It is equipped with the air door for providing coal dust for boiler.During boiler operatiopn, air door open, by coal pulverizer by coal finely disintegrated simultaneously
It is blown into the burner hearth of boiler.While boiler is out of service, coal pulverizer is stopped, air door will be closed.
Traditional suspension type hot air disperser contains doorframe and door-plate, has lock shaft and shifting in door-plate one side not adjacent with doorframe
Door-hinge, lock shaft and sliding door axle are in parallel between lateral arrangement and the two.Wherein, having on lock shaft can be with its synchronous axial system
Cam, its one end in rotatable shape through doorframe a munnion after extend.Lock shaft overhanging end top has in vertical cloth
The locking cylinder put, locking cylinder upper end is hinged on doorframe, there is pivoted arm, pivoted arm between locking cylinder lower end and lock shaft overhanging end
One end is fixedly connected with lock shaft overhanging end, and the other end is hinged with locking cylinder lower end.One end connection of the sliding door axle
In the respective face of door-plate, the other end is through outside another munnion of doorframe and being connected with push-and-pull cylinder.Outside the upper transverse frame of doorframe
Have on side in the guide rail of lateral arrangement, there is at least two directive wheels in guide rail, the directive wheel by hinge-type hinge with
The top of door-plate is hinged.During boiler operatiopn, by the flexible of locking cylinder, and lock shaft is driven to rotate by pivoted arm,
The side higher of the cam on lock shaft is unclamped door-plate and is departed from doorframe, then drive door-plate right by push-and-pull cylinder and sliding door axle
Move, so as to realize the opening of air door.And when boiler is out of service, coal pulverizer is stopped, then first by push-and-pull cylinder and shifting
Door-hinge drives door-plate to move to left to the state of closing the door, then by the flexible of locking cylinder, and drive lock shaft to rotate by pivoted arm, make lock
Cam side higher on mandrel holds out against door-plate, closed between door-plate and doorframe so as to realize.Although adopt in this way can be with
Realize it is closed between door-plate and doorframe, but when operator operation locking cylinder the side higher of the cam on lock shaft is held out against door-plate
When, locking cylinder should be stopped, and because operator's operational error makes the piston rod of locking cylinder be stretched under continuing, can make lock
Mandrel is rotated further, so that the cam side higher on lock shaft departs from door-plate, makes hot blast excessive.And the temperature of hot blast is up to
380 DEG C, such as now there are operating personnel or maintainer on the scene, the accident that can cause casualties occurs.
Utility model content
Problem to be solved in the utility model was to provide a kind of suspension type hot air disperser.Using this hot air disperser, can avoid
Maloperation and personnel casualty accidentses occur.
Above mentioned problem to be solved in the utility model is realized by following technical scheme：
Suspension type hot air disperser of the present utility model includes doorframe and door-plate, has locking in door-plate one side not adjacent with doorframe
Axle and sliding door axle, lock shaft and sliding door axle are in parallel between lateral arrangement and the two.Wherein, having on lock shaft can be with its synchronization
The cam of rotation, its one end in rotatable shape through doorframe a munnion after extend.Lock shaft overhanging end top has
The locking cylinder being vertically arranged, locking cylinder upper end is hinged on doorframe, is had between locking cylinder lower end and lock shaft overhanging end and is turned
Arm, pivoted arm one end is fixedly connected with lock shaft overhanging end, and the other end is hinged with locking cylinder lower end.The one of the sliding door axle
End is connected in the respective face of door-plate, and the other end is through outside another munnion of doorframe and being connected with push-and-pull cylinder.Doorframe it is upper
Have on horizontal outer frame side in the guide rail of lateral arrangement, there are at least two directive wheels in guide rail, the directive wheel is by hinge-type
Hinge is hinged with the top of door-plate.Locking cylinder lower section limited location mechanism is characterized in, the position-limit mechanism is located at pivoted arm
On the pivoted arm lower position offseted with pivoted arm when going to its longitudinal centre line in near-horizontal state.
Further improvement of the utility model scheme is that have supporting plate behind locking cylinder, and the supporting plate is parallel with door-plate,
One vertical edge is connected on the left-vertical pane of doorframe, and the position-limit mechanism is fixed in the supporting plate at neighbouring locking cylinder.
Position-limit mechanism therein is any one in block, bumping post or triangle frame.
As can be seen from the above scheme, due to the limited location mechanism below locking cylinder, the position-limit mechanism turns positioned at pivoted arm
On the pivoted arm lower position offseted with pivoted arm when to its longitudinal centre line being in near-horizontal state.At closing time, when operator operates
While locking cylinder makes the side higher of the cam on lock shaft hold out against door-plate, with locking cylinder lower end and lock shaft overhanging end phase
Pivoted arm even is blocked on position-limit mechanism so that locking cylinder is stopped.Compared with background technology, it is to avoid due to operator
Operational error makes the piston rod of locking cylinder stretch and be rotated further lock shaft, make the side higher of the cam on lock shaft under continuing
Depart from door-plate, the excessive situation of hot blast occur, so as to avoid the generation of personnel casualty accidentses.
