Description
Technical field
The utility model relates to a kind of wind blocking door.Specifically, be mounted in coal pulverizer entrance, steam power station, be used for blocking the overturn type insulation gate of the hot blast that warm air duct sends here, be applicable to when coal pulverizer keeped in repair the hot blast of its entrance is isolated.
Background technology
All know all be furnished with five to six coal pulverizers on each generating set of steam power station in power industry, need again to send in the burner hearth of boiler by the hot blast of higher temperature through the coal dust that coal pulverizer processes.Therefore, the hot blast temperature of coal pulverizer entrance up to 450 ℃ about.For guaranteeing that every coal pulverizer can both operate as normal, require coal pulverizer take turns maintenance and maintenance.And coal pulverizer is overhauled with maintenance process in, for guaranteeing that maintenance and attendant can enter in the coal pulverizer, need isolated door to be set and avoid hot blast to enter coal pulverizer in the coal pulverizer entrance, with realize maintenance and when safeguarding the temperature in the coal pulverizer be in the scope that people's physical efficiency bears.
At present, the isolated door that uses in the coal pulverizer entrance mostly is the isolated door of board plug type, and the isolated door of this board plug type is made up of doorframe and door-plate.Doorframe is fixed on the entrance of coal pulverizer, the relative both sides of its external surface are respectively arranged with slot, the relative both sides of door-plate are moving type respectively inserts in the associated socket, and realizes the closing or opening of door-plate (promptly insert or extract out) by a driving mechanism such as cylinder.Hot blast enters coal pulverizer when overhauling or safeguarding in order to avoid, and is provided with weather strip between around door-plate and the doorframe.Though between around door-plate and the doorframe, be provided with weather strip and can avoid hot blast to enter coal pulverizer, but because closing or opening of door-plate is to realize by the push-and-pull of door-plate in the doorframe slot, often push-and-pull, weather strip is easy to wear, fragile, makes that the life-span of weather strip is not long.Again because closing or opening of door-plate is by driving mechanisms such as cylinders door-plate to be carried out push-and-pull to realize, and driving mechanism can only be connected with one side of door-plate, in the push-and-pull process, especially in promoting the process of door-plate, door-plate has only stressed on one side, and thermal deformation takes place easily.Therefore door-plate, adopts the isolated door of this board plug type in case distortion just is difficult to realize sealing between itself and doorframe, and sealing effectiveness is poor, even descend the interior temperature of coal pulverizer still up to more than 80 ℃ in off position, personnel enter coal pulverizer and overhaul or safeguard very dangerous.
The utility model content
Problem to be solved in the utility model provides a kind of overturn type insulation gate.Adopt this overturn type insulation gate, not only can prolong the weather strip application life between door-plate and doorframe, and good sealing effect, can reduce the temperature in the coal pulverizer in off position down, the raising personnel enter the safety that coal pulverizer overhauls or safeguards.
For addressing the above problem, take following technical scheme:
Overturn type insulation gate of the present utility model contains doorframe, door-plate and driving mechanism, is characterized in also comprising the air channel, and this air channel is that cross section is the pipeline of rectangle, and its two ends are respectively air intake and air outlet.Described doorframe is fixed on air outlet one end in air channel.Door-plate is in the doorframe inboard, and door-plate top and doorframe top are hinged, door-plate and doorframe around between weather strip is arranged.Air channel air intake end and air opening end top have fixedly key seat and spacing key seat respectively, on the air channel upper wall of spacing key seat inboard through hole are arranged.Described driving mechanism is in fixedly between the key seat and spacing key seat, and the one end is hinged on fixedly on the key seat, the other end by mutual hinge actuating arm, slave arm and connecting rod and pass described through hole and the door-plate external surface is hinged.All there is limit pin hole the centre of actuating arm and the upper end of spacing key seat, are furnished with spacer pin in the limit pin hole wherein.Under door opening state, actuating arm is fixed on the spacing key seat by spacer pin and limit pin hole.
Described fixedly key seat and spacing key seat are formed by two pin ears, and this two couples pin ear is all along the horizontal positioned opposite at top, air channel.Wherein, fixedly between two of key seat pin ear upper ends crossbeam is arranged, driving mechanism one end is hinged on the centre of this crossbeam.
In the outside of door-plate two vertical convex tendons are arranged, the bearing pin of hinge usefulness is the axle of having strong market potential between actuating arm and slave arm, and the length of this axle of having strong market potential is greater than the spacing of two vertical convex tendons, in the middle of the hinged axle of having strong market potential in actuating arm lower end.Slave arm has two, connecting rod has two pairs, the upper end of two slave arms is hinged on the two ends of the axle of having strong market potential respectively, and the lower end of two slave arms is hinged with the upper end of two pairs of connecting rods respectively, and the lower end of two pairs of connecting rods then is hinged on respectively on two vertical convex tendons of door-plate outside.
Take such scheme, have the following advantages:
By such scheme as can be seen, because its driving mechanism one end of overturn type insulation gate of the present utility model is hinged on the fixedly key seat of doorframe top, the other end is hinged by actuating arm, slave arm and the connecting rod and the door-plate external surface that are hinged mutually, rely on the push-and-pull of driving mechanism to realize closing and opening, close with opening procedure in, do not produce friction between door-plate and weather strip, make weather strip not easy to wear, not fragile, prolong application life.
Again owing to its driving mechanism one end of overturn type insulation gate of the present utility model is hinged on the fixedly key seat of doorframe top, the other end is hinged by actuating arm, slave arm and the connecting rod and the door-plate external surface that are hinged mutually, rely on the push-and-pull of driving mechanism to realize closing and opening, driving mechanism links to each other with the external surface of door-plate, in the closed procedure of the pass of door-plate, the external surface of door-plate is stressed, by external surface reinforcing rib is set and makes the external surface of door-plate stressed evenly, thereby avoided door-plate generation thermal deformation at door-plate.Owing to avoided the thermal deformation of door-plate, guaranteed the excellent sealing between itself and doorframe.Therefore, adopt this overturn type insulation gate, good sealing effect descends the temperature in the coal pulverizer to have only 26～30 ℃ in off position, and near normal temperature, the personnel that make enter coal pulverizer and overhaul or safeguard very safe.
