Abstract
Provided is a front feeding system of a boiler. According to the system, two belt conveyors are arranged at a feed port of the top of a stock bin; a fuel guide chute inclining towards the rear wall of the stock bin is arranged in a machine head at the output end of the first belt conveyor, the fuel guide chute can make fuel conveyed by the first belt conveyor be conveyed to the middle of the rear wall of the stock bin, and a slope inclining forwards is formed in the stock bin; a fuel block board and a fuel distribution device are arranged in a machine head at the output end of the second belt conveyor, the fuel block board and the fuel distribution device make the fuel conveyed by the second belt conveyor be evenly distributed on the left side and the right side of the rear wall of the stock bin, and a slope inclining forwards is formed in the stock bin; a longitudinal fuel poking device and transverse fuel poking devices are arranged at the lower portion of the stock bin; a shaftless screw feeder and a discharge port are arranged at the bottom of the stock bin. Due to the fact that the two belt conveyors are arranged in parallel, the conveying amount of materials is large, no accumulation phenomenon exists, the requirements for the fuel of the boiler can be met, the fuel is saved, safety production is facilitated, and feeding cost is lowered.
Description
Technical field
The utility model relates to a kind of boiler stokehold feeding system, belongs to boiler technology field.
Background technology
As everyone knows, each boiler has stokehold feeding system, and he sends into material the main running device of boiler internal combustion from stock ground transhipment belt, and material will directly affect the stable operation of boiler safety in the smooth and easy situation of its links running.After fuel in silo, at conveyer, transport under the effect of inertia, fuel is all delivered to feed bin right side, causes feed bin left side fuel few, and feed in service is monolateral, boiler operatiopn is unstable, if want left side to have material, must the fuel accumulation on right side is very high, cause right side fuel easily to build bridge in feed bin, make feed not smooth, cause enterprise to have the defects such as production efficiency is low, and cost is high, poor stability.
Summary of the invention
For overcoming the above-mentioned defect of existing boiler front-furnace feeding device, the utility model provides a kind of boiler stokehold feeding system, in order to enhance productivity, reduces production costs, and increases the security of operation of boiler.
For solving its technical problem, the technical solution adopted in the utility model is: the boiler stokehold feeding system of designing is comprised of belt conveyor and stokehold feed bin, its feature is: 1, on the top fed mouth of feed bin, be provided with two belt conveyors, wherein in the output head of the first belt conveyor, be provided with the deflector chute of wall after tendency feed bin, this deflector chute makes fuel that belt conveyor is sent here deliver to wall middle part after feed bin, and in storehouse, forms the gradient turning forward; In the output head of the second belt conveyor, be provided with striker plate and sub-material pants, this striker plate and sub-material pants divide equably to the ，Bing storehouse, the left and right sides of wall after feed bin fuel that belt conveyor is sent here and form the gradient turning forward; In the bottom of feed bin, be provided with longitudinal setting gauge and horizontal setting gauge; In the bottom of feed bin, be provided with shaftless screw(-type) feeder and discharging opening, under the driving of this shaftless screw(-type) feeder motor outside storehouse, storehouse fuel released from discharging opening;
2, the bandwidth of the belt of every conveyer is 1 meter, and length is 3-10 rice;
3, described feed bin is comprised of a great Cang and three little storehouse two parts, is designed with 6 groups every group 2 totally 12 longitudinal setting gauges between great Cang and little storehouse, and material stock in large storehouse is sent into little storehouse uniformly; In each little storehouse, be furnished with the shaftless screw(-type) feeder of 2 conveying use, the fuel in little storehouse is sent into boiler continuously by discharging opening, in small feed bin exit, be provided with 2 horizontal setting gauges that prevent that small feed bin outlet from stopping up.
Compared with prior art, the utility model has following features and progress:
1, owing to being provided with two belt conveyors and being arranged in parallel, material upwards of movement is large, can not produce packing phenomenon, can meet the demand of boiler to fuel, is conducive to fuel saving and safety in production; After transformation, the conveying of two, stock ground can, simultaneously to storehouse, stokehold material loading, can reduce material loading cost;
2, the utility model is simple in structure, can alleviate workman's work.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, First belt conveyor, 2, second belt conveyors, 3, striker plate, 4, deflector chute, 5, sub-material pants, 6, feed bin, 7, longitudinal setting gauge, 8, horizontal setting gauge, 9, shaftless screw(-type) feeder, 10, discharging opening.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
With reference to accompanying drawing, on the top fed mouth of feed bin 6, be provided with two belt conveyors, wherein in the output head of the first belt conveyor 1, be provided with the deflector chute 4 of wall after tendency feed bin, this deflector chute makes fuel that belt conveyor is sent here deliver to wall middle part after feed bin, and in storehouse, forms the gradient turning forward; In the output head of the second belt conveyor 2, be provided with striker plate 3 and sub-material pants 5, this striker plate, and sub-material pants divide to the ，Bing storehouse, the left and right sides of wall after feed bin fuel that belt conveyor is sent here to form the gradient turning forward equably; 2. in the bottom of feed bin 6, be provided with longitudinal setting gauge 7 and horizontal setting gauge 8; 3, in the bottom of feed bin, be provided with shaftless screw(-type) feeder 9 and discharging opening 10, under the driving of this shaftless screw(-type) feeder motor outside storehouse, storehouse fuel be pushed out to boiler from discharging opening.
Wherein: the bandwidth of the belt of described belt conveyor is 1 meter, length is 3-10 rice;
Described feed bin 6 is comprised of a great Cang and three little storehouse two parts, is designed with 6 groups every group 2 totally 12 longitudinal setting gauges 7 between great Cang and little storehouse, and material stock in large storehouse is sent into little storehouse uniformly; In each little storehouse, be furnished with the shaftless screw(-type) feeder 9 of 2 conveying use, the fuel in little storehouse is sent into boiler continuously by discharging opening 10, in small feed bin exit, be provided with 2 horizontal setting gauges 8 that prevent that small feed bin outlet from stopping up.
