A locking cylinder is arranged on the door frame neighboring the extended end of the locking shaft, and one end of the locking cylinder is fixedly connected with the door frame and the other end of the locking cylinder is connected with the extended end of the locking shaft. One end of the door-shaft is fixed on the door-board and the other end of the door-shaft is movably arranged on the other erect side-frame of the door-frame and extends out of the frame. A pushing cylinder is arranged on the outer side of the door frame which neighbors the extended end of the door-shaft, and one end of the pushing cylinder is fixed on the outer side of the door-frame and the other end of the pushing cylinder is connected with the extended end of the door-shaft. The utility model is characterized in that a guide-rail is arranged above one side of the door frame neighboring the door board; the guide-rail is horizontally arranged and a guide-wheel is arrange in the guide-rail; the guide-wheel is hinged with the upper edge of the door board through a hinge and then the door board is asway suspended under the upper side-frame of the door frame. The suspending-type hot-air door has low failure probability and low maintaining cost, and can guarantee the normal running of boiler. The utility model is applied to provide coal for boilers of a power station.
Description
Technical field
The utility model relates to a kind of air door.Be to be used for the coal dust that flour mill grinds is sent into the suspension type hot blast door of boiler specifically, be applicable to that thermal power station is the boiler coal supply.
Background technology
At present, on the boiler of thermal power station, all be furnished with coal pulverizer, be processed with on the coal pulverizer and be used for providing the air door of coal dust for boiler.During boiler operatiopn, this air door is opened, and is blown into when by coal pulverizer coal being clayed into power in the burner hearth of boiler.When boiler is out of service,, air door can be closed in the out-of-work while of coal pulverizer.
Traditional air door all is to adopt in its door-plate bottom guide wheel and guide rail are installed.When door-plate moves, not only to overcome frictional force between door-plate and the guide rail and the frictional force between guide wheel and the guide rail.Simultaneously, because guide rail is in door-plate bottom, the easy ash that falls, door-plate also will overcome the resistance that dust stratification brings when mobile.In case dust stratification is serious in the guide rail, can cause door-plate to move and be obstructed.In case and door-plate moves and is obstructed, just need to shut down to keep in repair.Therefore, this air door is fault rate height, maintenance cost height not only, also can influence the normal operation of boiler.
The utility model content
Problem to be solved in the utility model provides a kind of suspension type hot blast door.This suspension type hot blast door, fault rate is low, maintenance cost is low, can guarantee the normal operation of boiler.
For addressing the above problem, take following technical scheme:
Suspension type hot blast door of the present utility model comprises doorframe and door-plate.Be the sealing shape between door-plate and doorframe and be connected, lock shaft is arranged on its not adjacent with doorframe one side and move door-hinge.Said lock shaft and move door-hinge and be lateral arrangement and be parallel to each other.Wherein, cam is arranged on the lock shaft, the one end is on the vertical edge frame that rotatable shape is installed in doorframe and extends.Near on the doorframe at lock shaft overhanging end place locking cylinder is arranged, this locking cylinder is vertical with lock shaft, and the one end is connected mutually with doorframe, and the other end links to each other with the lock shaft overhanging end.An end that moves door-hinge is fixed on the door-plate, and its other end is on another vertical edge frame that moving type is installed in doorframe and extends.Near the doorframe outside of moving door-hinge overhanging end place propulsion cylinder is arranged, this propulsion cylinder with move door-hinge and be on the same level, the one end is fixed on the doorframe outside, the other end with move the door-hinge overhanging end and link to each other.Be characterized near the doorframe one side top of door-plate guide rail being arranged, this guide rail is lateral arrangement, and directive wheel is arranged in it.Said directive wheel is hinged by hinge-type hinge and door-plate upper edge, and make door-plate be the swing shape be suspended under the upper side frame of doorframe.
Take such scheme, have the following advantages:
Because the utility model is having guide rail near above doorframe one side of door-plate, this guide rail is lateral arrangement, and directive wheel is arranged in it.Said directive wheel is hinged by hinge-type hinge-type hinge and door-plate upper edge, and door-plate be the swing shape be suspended under the upper side frame of doorframe.Make door-plate only have the rolling friction of Points And lines in moving process, avoided the friction of face, frictional force is relatively disperseed, and resistance is less.Again because guide rail is in doorframe top, can dust stratification in the guide rail, avoided because the door-plate that the guide rail dust stratification brings moves the situation generation of being obstructed, thereby not only reduced fault rate and maintenance cost, can also guarantee the normal operation of boiler.
Description of drawings
Fig. 1 is a suspension type hot blast door schematic diagram of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, suspension type hot blast door of the present utility model contains doorframe 11 and door-plate 2, door-plate 2 vertically be length and laterally be width respectively greater than the length and the width of doorframe inner side edge, it is sealing shape by sealing strip 12 with 11 on doorframe and cooperates when closing.Top, doorframe 11 1 sides near door-plate 2 is equipped with guide rail 6, this guide rail is lateral arrangement, two directive wheels 5 are installed in it, these two directive wheels link together by the upper edge of a hinge-type hinge 7 with door-plate 2 respectively, thereby door-plate 2 is suspended under the guide rail 6, and can be to two face direction swing under the effect of hinge-type hinge 7.The one side that door-plate 2 is not adjacent with doorframe 11 is provided with two lock shafts 10 and one and moves door-hinge 9, and these two lock shafts and one move door-hinge and all is between lateral arrangement and they and parallels.Wherein, two lock shafts 10 are the upper and lower part that symmetry shape is arranged in door-plate 2, move door-hinge 9 and then are between two lock shafts 10.Two cams 1 all are installed on two lock shafts 10.Be processed with two through holes accordingly on two vertical edge frames of doorframe 11, the two ends of two lock shafts 10 are rotatable shape by bearing and penetrate in this two through hole, and their same end extends.Doorframe 11 arranged outside near lock shaft 10 overhanging end places have two locking cylinders 4.Two trivial tight cylinders 4 are vertical with lock shaft 10, and they are in the above and below of lock shaft 10 respectively, and their end is fixed on the outside upper and lower of doorframe 11, and their other end is connected with the lock shaft 10 of upper and lower respectively.Can drive lock shaft 10 rotations by two locking cylinders 4, the rotation of lock shaft 10 can drive cam 1 rotation on it again, thereby makes door-plate 2 press to doorframe 11 1 sides, realizes the sealing of 11 on door-plate 2 and doorframe.
Said door-hinge 9 one ends that move are fixed on the door-plate 2 by pressing plate 3 and screw.Is processed with through hole in the middle of another vertical edge frame of doorframe 11, the other end that moves door-hinge 9 is and extends after moving type penetrates this through hole.Be provided with a propulsion cylinder 8 near moving door-hinge 9 overhanging ends one side, this propulsion cylinder with move door-hinge 9 and be in same horizontal seat and set up, the one end is fixed on doorframe 11 outsides, the other end with move door-hinge 9 overhanging ends and link to each other.By stretching of propulsion cylinder 8, can realize the move left and right of door-plate 2, thereby realize opening and closing of air door.
