Description
Technical field
The present invention relates to a kind of dry-type slag extractor shutoff door, especially relate to a kind of under not blowing out situation, the shutoff door device that dry-type slag extractor is overhauled.
Background technology
The raising of, water saving energy-conservation along with country, environmental requirement, coal-fired station's dry slag disposal have become the at first scheme of present boiler slagging-off.The dry slag disposal system is the convective motion that utilizes between ambient, cool air and the warm sludge, carries out heat exchange, discharges thereby make warm sludge obtain cooling off the back, and ambient, cool air enters burner hearth under the combustion chamber draft effect after heating, participate in burning.And the key equipment of finishing said process is exactly a dry-type slag extractor.
Dry-type slag extractor and system equipment thereof, be by many covers separately separate equipment constitute.Equipment has some equipment unavoidably and operation troubles occurs in running, needs maintenance.
Existing dry-type slag extractor always needs first shutdown when overhauling, line operate again, however boiler is as the main process equipment in power plant, because of the shutdown of stopping working of the glitch of equipment, caused the significant wastage of resource, and the cost of overhaul is higher.
In addition, in the prior art, coal because a variety of causes, can form lumpiness, coke button that hardness is different in the boiler combustion process.The wet type that adopts water to cool off is removed slag system, after warm sludge meets cooling water, can produce cracking by nature, makes coke button cracking refinement.And the dried slag removing system that adopts natural wind to cool off, coke button is in being subjected to Air-cooling Process, and not cracking voluntarily has only by external force ability broken.Big coke block is as can not get fragmentation, directly enter dry-type slag extractor after, can have influence on the cooling effect of coke button core on the one hand, running environment, personal safety are brought harm.On the other hand, the conveying of big coke block in equipment also has difficulties.
Summary of the invention
At the deficiencies in the prior art, the technical problem that the present invention solves provides a kind of dry-type slag extractor shutoff door, this dry-type slag extractor with shutoff door on the one hand when equipment such as dry-type slag extractor need not shutdown maintenance, play isolating door shutoff effect, make high temperature furnace slag directly be deposited on the door-plate, and can not enter follow-up equipment; On the other hand, if during big coke block,,, can play precrushing purpose to big coke block by means of the thrust of door-plate to big coke block by the operation of door-plate.Thereby be the safe and reliable operation of dry-type slag extractor, further safety guarantee is provided, guaranteed environment, personal safety, the possibility of having avoided accident to take place.
For solving the problems of the technologies described above, technical scheme of the present invention is achieved in that
A kind of dry-type slag extractor shutoff door comprises that one is arranged at the gate seat between slag bucket and the dry-type slag extractor, and wherein, described dry-type slag extractor also comprises the door-plate that is used to cut off on the described gate seat of being movably installed in of described slag bucket and described dry-type slag extractor with shutoff door.
Further, described door-plate comprises a left-hand door plate and a right door-plate, and described left-hand door plate and described right door-plate are meshing with each other when cutting off described slag bucket and described dry-type slag extractor.
Described dry-type slag extractor also comprises the drive unit that described left-hand door plate of driving and described right door-plate move with shutoff door on described gate seat.
Described drive unit comprises one group of drive unit that is connected in described left-hand door plate and described right door-plate respectively at least.
Described dry-type slag extractor also comprises a horizontal track with shutoff door, and described left-hand door plate and described right door-plate are installed on the described horizontal track, and can move along described horizontal track.
Described left-hand door plate is respectively equipped with the tooth that intersection meshes with described right door-plate at relative top.
Compared with prior art, the invention has the beneficial effects as follows: maintenance is convenient, the cost of overhaul is lower, and carry smooth and easy, security performance is higher.
Description of drawings
Below in conjunction with drawings and Examples technical solution of the present invention is described further:
Fig. 1 is a dry-type slag extractor shutoff door vertical view in the most preferred embodiment of the present invention.
Fig. 2 is the front view that dry-type slag extractor is used shutoff door in the most preferred embodiment of the present invention.
Wherein:
The right door-plate of 1 gate seat 2a left-hand door plate 2b
The 3a first driving mechanism 3b second driving mechanism 3c the 3rd driving mechanism
3d 4 wheel driven actuation mechanism 4 horizontal guide rails 5 teeth
6 slag buckets, 7 dry-type slag extractors, 8 connecting rods
The specific embodiment
As shown in Figure 1 and Figure 2, the dry-type slag extractor of the present invention preferred forms of shutoff door, the gate seat 1 of described shutoff door device is installed between slag bucket 6, the dry-type slag extractor 7.Gate seat 1 is provided with left and right door-plate 2a, the 2b of level run in opposite directions.Left and right door-plate 2a, 2b are installed on the horizontal track 4.Be fixing rigid body between horizontal track 4 and the gate seat 1.Left and right door-plate 2a, 2b link to each other by connecting rod 8 with the first driving mechanism 3a, the second driving mechanism 3b, the 3rd driving mechanism 3c, 4 wheel driven actuation mechanism 3d respectively.The first driving mechanism 3a, the second driving mechanism 3b, the 3rd driving mechanism 3c, 4 wheel driven actuation mechanism 3d can adopt electronic, also can adopt hydraulic-driven, and be fixed on the gate seat 1.In order to increase the stationarity of left and right door-plate 2a, 2b motion process, every door-plate all adopts double driving mechanism to drive, promptly be that the first driving mechanism 3a, the second driving mechanism 3b are one group, drive left-hand door plate 2a, the 3rd driving mechanism 3c, the moving 3d of 4 wheel driven are another group, drive right door-plate 2b, when work, the first driving mechanism 3a, the second driving mechanism 3b, the 3rd driving mechanism 3c, 4 wheel driven actuation mechanism 3d are under dynamic action, drive left and right door-plate 2a, 2b respectively on horizontal guide rail 4, moving linearly is finished unlatching, closing motion.When left and right door-plate 2a, 2b are in the position, top, this device is a closed condition, the high temperature furnace slag that boiler combustion forms all is deposited on left and right door-plate 2a, the 2b, and dry-type slag extractor 7 equipment such as grade of bottom can overhaul, and promptly play the shutoff effect to the boiler bottom slag.
In the process that high temperature furnace slag falls by this device, if when having the high temperature big coke block of stipulating above certain size can not pass through the grid space of horizontal guide rail 4 formation, then left and right door-plate 2a, 2b move under the driving force effect of the first driving mechanism 3a, the second driving mechanism 3b, the 3rd driving mechanism 3c, 4 wheel driven actuation mechanism 3d, left and right door-plate 2a, 2b are in the process of operation in opposite directions, and be broken the big coke block top.In order to improve left and right door-plate 2a, 2b in motion process, push up the effect of broken big coke block, at the top of left and right door-plate 2a, 2b, be provided with the tooth 5 of intersection engagement.By this device, played effect to the big coke block precrushing.
What deserves to be mentioned is: this device can be formed the complete shutoff door of a cover by one or more groups door-plate.
Although be the example purpose, preferred implementation of the present invention is disclosed, but those of ordinary skill in the art will recognize that under situation about not breaking away from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
