Description
Technical field
The utility model relates to the technical field of combustion apparatus supplying powder fuel.
Background technology
The examination requirement relevant according to Industrial Boiler, the bunker coal of boiler must, through metering and integrating, must be determined usage quantity and the energy-saving effect of bunker coal.In prior art, some boiler also uses platform balance to carry out Weighing to bunker coal in stokehold, make operating personnel's labour intensity large, owing to can not accurately controlling Coal-fired capacity, also causes the environmental pollution of boiler room.Along with the development of sensor technology, utilize LOAD CELLS that boiler oil coal is carried out real time monitoring and accurately controlled, become the important technological improvement target of pulverized-coal fired boiler.
Utility model content
Technical problem to be solved in the utility model is to provide the coal conveyor that a kind of coal dust conveying capacity can be controlled automatically, has the indoor Coal-fired capacity of input boiler combustion is carried out to the feature of accurately controlling.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: the coal conveyor that a kind of coal dust conveying capacity can be controlled automatically, comprises coal conveyor, firing machine, LOAD CELLS and intelligent controller; The coal delivery cylinder inside of described coal conveyor is provided with spiral propeller, and spiral propeller drives by defeated coal motor, in described coal delivery cylinder upper shed and be communicated with the coal bunker of firing machine, is provided with coal impeller and drives by coal motor in coal bunker; Described LOAD CELLS is arranged on coal delivery cylinder and by holding wire and is connected with intelligent controller, text controller and frequency converter are also housed on intelligent controller, described text controller is connected with LOAD CELLS by holding wire, and described frequency converter is connected between text controller and coal motor by holding wire.
The further improvement that the utility model is done is: also comprise into coal vertical tube, blast pipe, air blast and boiler furnace; The right-hand member coal outlet of described coal delivery cylinder with enter coal vertical tube inside and be connected, the right-hand member coal outlet upper end of coal delivery cylinder is provided with hinged cover plate, the bottom of entering coal vertical tube is connected with the middle part of blast pipe by elbow, and described blast pipe is communicated with between air blast and boiler furnace.
The beneficial effect that adopts technique scheme to produce is: the utility model can make the coal-feeding quantity of whole coal conveyor remain on rational scope, makes to enter the indoor coal dust of boiler combustion and fully burns and do not waste, and realizes the object of saving bunker coal.The right-hand member coal outlet upper end of coal delivery cylinder is provided with hinged cover plate, can prevent that the air quantity of air blast from revealing from coal delivery cylinder.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
As shown in the figure: 1 defeated coal motor, 2 coal motors, 3 coal bunkers, 4 intelligent controllers, 5 LOAD CELLSs, 6 frequency converters, 7 text controllers, 8 cover plates, 9 enter coal vertical tube, 10 load cell signal lines, 11 coal delivery cylinders, 12 spiral propellers, 13 boiler furnaces, 14 blast pipes, 15 air blasts.
Detailed description of the invention
Contrast Fig. 1 uses step to be described further to operation of the present utility model: the coal conveyor that a kind of coal dust conveying capacity can be controlled automatically, comprises coal conveyor, firing machine, LOAD CELLS and intelligent controller 4; Coal delivery cylinder 11 inside of described coal conveyor are provided with spiral propeller 12, and spiral propeller 12 drives by defeated coal motor 1, in described coal delivery cylinder 11 upper sheds and be communicated with the coal bunker 3 of firing machine, be provided with coal impeller and drive by coal motor 2 in coal bunker 3; Described LOAD CELLS is arranged on coal delivery cylinder 11 and by holding wire and is connected with intelligent controller 4, text controller 7 and frequency converter 6 are also housed on intelligent controller 4, described text controller 7 is connected with LOAD CELLS 5 by holding wire, and described frequency converter 6 is connected between text controller 7 and coal motor 2 by holding wire.Also comprise into coal vertical tube 9, blast pipe 14, air blast 15 and boiler furnace 13; The right-hand member coal outlet of described coal delivery cylinder 11 with enter coal vertical tube 9 inside and be connected, the right-hand member coal outlet upper end of coal delivery cylinder 11 is provided with hinged cover plate 8, the bottom of entering coal vertical tube 9 is connected with the middle part of blast pipe 14 by elbow, and described blast pipe 14 is communicated with between air blast 15 and boiler furnace 13.The intelligent controller that the present embodiment adopts is CM8006H type, and LOAD CELLS is YZC-526 type adapted steel formula cantilever beam.The intelligent controller that the utility model is installed inputs to text controller 7 and frequency converter 6 by LOAD CELLS collection signal, controls the rotating speed of firing machine motor 2, and the coal dust in the coal delivery cylinder 11 of coal conveyor is accurately controlled.Set the definite value of a coal dust conveying capacity by text controller 7, if the coal dust amount in coal delivery cylinder 11 is overweight, frequency converter 6 is controlled coal motor 2 and is made it rotating speed reduction, if the coal dust amount in coal delivery cylinder 11 reduces, frequency converter 6 is controlled coal motor 2 and is made it rotating speed raising, can make like this coal-feeding quantity of whole coal conveyor remain on rational scope, make the coal dust entering in boiler furnace 13 fully burn and not waste, realize the object of saving bunker coal.
