Abstract

The utility model relates to a coal feeding device for a boiler. The utility model is mainly composed of a fixed plate (1), a coal pushing plate (2), an eccentric wheel (3), a connecting rod (4), a bracket (5), a rotary shaft (6), a driven chain wheel (7), a driving chain wheel (8), a chain (9), a speed reducer (10), a shaft coupling (11) and a motor (12), wherein, the eccentric wheel (3) is driven by the rotation of the rotary shaft (6) to rotate, the coal pushing plate (2) can move in a reciprocating mode on the fixed plate (1), and fuel can be pushed on a endless grate (15). A burning mode from bottom to top can be realized, briquette can be completely burned, and the utility model opens a road for popularizing briquette.

Description

Coal supply apparatus for boiler
The utility model belongs to coal feeder, relates in particular to a kind of industrial chain furnace grate and burns the coal feeder that moulded coal is used.
Existing large and medium-sized industrial machinery boiler, mostly adopt traveling-grate stoker, fuel is from coal feed point, traveling-grate stoker by motion is brought burner hearth into, rely on the heat radiation of burner hearth, by progressively burning downwards of top layer, and air blast is to blow from bottom to top, causes certain obstruction for downward burning, during especially to the burning moulded coal, moulded coal can not be grilled thoroughly fully, even cause and stop burning, can burn moulded coal in order to make boiler, people have added combustion adjuvant in moulded coal, the moulded coal cost is increased, and the problem but also unresolved boiler stops burning is unfavorable for applying of moulded coal.
The purpose of this utility model provides a kind of making and has the coal feeder that chain grate boiler can burn moulded coal fully now.
The purpose of this utility model is achieved in that it is mainly by fixed head, coal-pushing plate, eccentric wheel, connecting rod, support, turning cylinder, formed by movable sprocket, drive sprocket, chain, decelerator, shaft coupling, motor; Two eccentric wheels are installed on the turning cylinder, connecting rod links up eccentric wheel and coal-pushing plate, one end of turning cylinder has one by movable sprocket, motor connects with input shaft of speed reducer by shaft coupling, one drive sprocket is arranged on the output shaft of decelerator, drive sprocket and had chain coupling, fixed head to be fixed on the below of traveling-grate stoker top, coal-pushing plate in the boiler between the movable sprocket, coal-pushing plate at the following coal mouth place of coal bunker by bracket supports.
During work, motor rotates through decelerator and drives the drive sprocket rotation, drive sprocket drives passive sprocket rotation by chain, thereby turning cylinder is rotated, turning cylinder rotates eccentric wheel is rotated, by connecting rod coal-pushing plate is moved back and forth, moulded coal is shifted onto on the fixed head, moulded coal on the fixed head ignites by the flame of burner hearth and heat radiation behind the top layer, shift onto on the traveling-grate stoker by coal-pushing plate, make below the moulded coal that catches fire translates into, thereby make the moulded coal on the traveling-grate stoker realize burning from the bottom up, solved the problem of starting to exchange fire that chain grate boiler burns moulded coal, moulded coal can be fired fully.
The utility model only need be installed on the existing boiler when using, do not need existing boiler is carried out structural change, so invest little, simple in structure, not only can burn moulded coal, can also burn small coal.Owing to changed the form of burning from top to bottom of conventional boiler, realized the mode of burning from the bottom up, make fuel completing combustion, saved fuel, improved the thermal efficiency.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
As shown in the figure, the 1st, fixed head, the 2nd, coal-pushing plate, the 3rd, eccentric wheel, the 4th, connecting rod, the 5th, support, the 6th, turning cylinder, the 7th, by movable sprocket, the 8th, drive sprocket, the 9th, chain, the 10th, decelerator, the 11st, shaft coupling, the 12nd, motor, the 13rd, boiler body, the 14th, coal bunker, the 15th, traveling-grate stoker.
Two eccentric wheels 3 are housed on the turning cylinder 6, one end of connecting rod 4 links to each other with eccentric wheel 3, the other end links to each other with coal-pushing plate 2, one end of turning cylinder 6 is equipped with one by movable sprocket 7, by chain 9, be in transmission connection by movable sprocket 7 and drive sprocket 8 on decelerator 10 output shafts, motor 12 links to each other with the power shaft of decelerator 10 by shaft coupling 11, and fixed head 1 is fixed on the top of the interior traveling-grate stoker 15 of boiler, the below of coal-pushing plate 2, coal-pushing plate 2 is supported by support 5 at the following coal mouth place of coal bunker 14.
During work, motor 12 rotates, slow down through decelerator 10, driving drive sprocket 8 rotates, rotate by chain 9 drive sprockets 8, can drive by movable sprocket 7 and rotate, thereby turning cylinder 6 is rotated, eccentric wheel 3 on the turning cylinder 6 rotates by connecting rod 4 coal-pushing plate 2 is moved back and forth, and moulded coal is shifted onto on the fixed head 1, and the moulded coal on the fixed head 1 ignites by the flame of burner hearth and heat radiation behind the surface, shift onto on the traveling-grate stoker 15 by continuous reciprocating coal-pushing plate 2 again, make below the moulded coal that catches fire translates into, thereby realize the mode of burning from the bottom up, make moulded coal completing combustion.
