Abstract
The utility model provides a feeding device which can automatically feed a chaff fuel to a boiler with the chaff as a fuel. The feeding device consists of a lower material storage hopper, an upper material storage hopper, a delivery pipeline and blowers, wherein, the lower material storage hopper and the upper material storage hopper are connected through an inclined delivery pipe; the upper material storage hopper is connected with the boiler through the delivery pipeline; blowers are installed on the delivery pipelines on the sides of the lower ends of the upper and the lower material storage hoppers; slag discharge holes are formed on the other sides of the lower ends thereof; a vale is installed on each slag discharge hole; an exhaust port is arranged at the top end of the upper material storage hopper; a dust collection bag is installed on the exhaust port; a return air pipeline is installed at the top end of the upper material storage hopper; one end of the return air pipeline is connected with the upper material storage hopper; the other end thereof is connected with a boiler grate port; and an observation window is arranged on the upper material storage hopper. The utility model overcomes the shortcoming of traditional corn choosing and chaff delivering method by manpower, realizes the delivery automation of chaff fuel and improves the heat efficiency of the boiler.
Description
Technical field
The utility model technology relates to a kind of combustion apparatus, especially a kind of fuel automatic supply device of boiler.
Background technology
The reinforced of at present traditional husk fuel boiler all is by artificial backpack, and the boiler feeding workman chooses husk in the boiler storage bin(hopper), by air blast husk fuel is blown in the boiler furnace and burns.
Mainly there are following defectives in traditional husk fuel boiler charging system: 1, the boiler storage bin(hopper) is high more than two meters apart from ground, manually choose to send to carry on a shoulder pole by springboard one and choose just and can finish, labor strength is big on the one hand, also has certain potential safety hazard on the other hand.2, manually choose material speed instability, be difficult to guarantee that the boiler storage bin(hopper) does not lack material always and influences boiler combustion.
Summary of the invention
The purpose of this utility model is to be to provide a kind of pay-off that can carry husk fuel automatically to the husk fuel boiler.
The purpose of this utility model is achieved in that
A kind of husk fuel boiler automatic feeding is by following storage bin(hopper), last storage bin(hopper), conveyance conduit, air blast is formed, following storage bin(hopper), last storage bin(hopper) is connected by a sloping transfer line road, last storage bin(hopper) is connected by conveyance conduit with boiler, on, on the one side conveyance conduit of following storage bin(hopper) lower end air blast is housed all, the opposite side conveyance conduit all has mud hole, mud hole is equipped with a valve, exhaust outlet is equipped with on last storage bin(hopper) top, exhaust outlet is equipped with a dust collecting sleeve, a return-air duct is equipped with on last storage bin(hopper) top, return-air duct one end connects goes up storage bin(hopper), one end connects the boiler grate mouth, and a perspective window is housed on the last storage bin(hopper).
Because the deficiency of taking to go up technical scheme, the utility model to overcome traditional carrying method produces the following effect of having a mind to:
1, storage bin(hopper) is installed on ground level down, significantly reduces manpower to choose potential safety hazard and the heavily physical demands that husk brings;
2, discharge the assorted slag (stone, silt particle) of husk fuel by two slag-drip openings, reduce of the wearing and tearing of assorted slag fire grate mouth and mucking machine;
3, by the absorption to the husk dust of dust collecting sleeve, reduced of the pollution of husk dust to the work-yard air;
4, be arranged at the wind-force that the combustion-supporting pipeline of fire grate mouth of storage bin(hopper) sends to the drain hopper air blast and send into burner hearth, combustion-supporting in advance to the boiler feed duct injection to the husk of burner hearth, husk is fully burned, the combustion rate of husk that proposition is high, reduce the consumption of husk fuel, improved the bulk temperature of burner hearth.
5, by automatic feeding, see through storage bin(hopper) perspective window, control husk amount of storage in the storage bin(hopper), balancedly husk is delivered to the boiler storage bin(hopper), storage bin(hopper) can not occur and lack material and the phenomenon of influence burning.
Thereby realized the purpose of invention preferably.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: 1, following storage bin(hopper), 2, air blast a, 3, mud hole a, 4, the sloping transfer line road, 5, go up storage bin(hopper), 6, dust collecting sleeve, 7, air blast b, 8, mud hole b, 9, the boiler feed pipeline, 10, return-air duct, 11, the perspective window.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Following storage bin(hopper) 1, last storage bin(hopper) 5 are connected by a sloping transfer line road 4, last storage bin(hopper) 5 is connected with boiler feed pipeline 9, on the conveyance conduit of upper and lower storage bin(hopper) lower end left side air blast 7 and 2 is housed all, the right side conveyance conduit all has mud hole 8 and 3, exhaust outlet is equipped with on last storage bin(hopper) 5 tops, exhaust outlet is equipped with a dust collecting sleeve 6, and a return-air duct 10 is equipped with on last storage bin(hopper) top, and return-air duct 10 1 ends connect goes up storage bin(hopper) 5, one end connects the boiler grate mouth, and a perspective window 11 is housed on the last storage bin(hopper).
Husk is stacked near the subsurface storage bin(hopper) 1,, husk is sent into down in the storage bin(hopper) 1, send conveyance conduit 4 to by air blast 2 and fall into and store hopper 5, husk slag (stone, silt particle) discharge when process mud hole 3 by artificial pinch moving husk; Husk enters burner hearth through air blast 7 by boiler feed pipeline 9 from storage bin(hopper), and dust collecting sleeve 6 automatic dust absorptions are regularly manually discharged in the bag inwall, and it is combustion-supporting that the wind-force that return-air duct 10 is sent air blast 3 are automatically delivered to burning place of burner hearth husk; Closure when mud hole 3,4 is flat, every work was opened the mud hole valve after 3～5 hours, slagging once, the operator grasps storage bin(hopper) material stock situations by glass photoscope 11, the control feeding speed.
Claims (3)
