Abstract
The utility model discloses a wind-power layering coal bucket, comprising a coal bucket main body, a star-shaped coal feeder and a coal gate, wherein the coal bucket main body is internally provided with a coal guide plate; the star-shaped coal feeder is arranged at the tail end of the coal guide plate; the coal gate is arranged above the star-shaped coal feeder; a coal screening device is arranged below the star-shaped coal feeder; and a high-pressure air pipe is arranged below the coal screening device. The wind-power layering coal bucket has a simple and reasonable structure; coal with different sizes can be distinguished by the coal screening device and the smaller coal can be blown into a hearth of a boiler to be rapidly and sufficiently combusted through wind power, so that the possibility of blocking seams among coal blocks by the coal is reduced; and blown air from the lower side of a fire grate penetrates through a coal layer through the seams among the coal blocks to drive combustion upwards, and thus the combustion efficiency of the coal is improved.
Description
Technical field
The utility model relates to a kind of storage tank, relates in particular to a kind of wind-force layering coal bunker.
Background technology
Because energy shortage both at home and abroad at present, price is high.Need in China under the general requirements of energy-saving and emission-reduction.Enterprise is badly in need of falling Ben Jiezhi again, strengthens enterprise competitiveness.And generally the energy accounts for about 30% of enterprise production cost.Energy prices are high has caused great burden for the production and operation of enterprise.Boiler is the major impetus source of all kinds of enterprise production.Boiler is main with fire coal mainly in the middle of the production process of enterprise at present.Boiler below 35 tons is main with traveling-grate stoker mainly again.The coal bunker that current boiler uses is to lean on the self gravitation of coal to be pressed on the fire grate fully, with coal flashboard control coal seam thickness.Because the comparison consolidation that the coal in the old-fashioned coal bunker is all pressed.The following coal dust content of 2mm accounts for about 45% of raw coal integral body in the raw coal.Raw coal gets into behind the burner hearth air blast and is not easy to penetrate the coal seam and carries out completing combustion.Its efficiency of combustion is merely 75-80%.Cause great energy waste, increased business burden.
The utility model content
The purpose of the utility model is to provide a kind of wind-force layering coal bunker to improve burning of coal efficient to above-mentioned defective.
The purpose of the utility model is to realize through following technical scheme:
A kind of wind-force layering coal bunker; Comprise coal bunker main body, star-like coal feeder and coal flashboard; Be provided with coal guide plate in the said coal bunker main body, said coal guide plate end is provided with star-like coal feeder, and said star-like coal feeder top is provided with the coal flashboard; Said star-like coal feeder below is provided with the coal sifter, and said coal sifter below is provided with high-pressure air hose.
Further, said coal flashboard connects coal flashboard adjusting gear, and said coal flashboard adjusting gear connects coal flashboard regulating handle.
Further, said high-pressure air hose is connected with high pressure positive blower through high-pressure blast storehouse flange.
Further, said coal bunker main body lower end is provided with inspection door.
The beneficial effect of the utility model is: simple and reasonable; The coal that varies in size is distinguished and less coal is blown into rapidly fully burning of boiler furnace through the coal sifter through wind-force; Reduce little coal and crammed the situation in slit between coal cinder; Make from the air blast of fire grate below and pass upwards burning of coal seam, improved the efficiency of combustion of coal through the gap between coal cinder.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the described a kind of wind-force layering coal bunker internal structure sketch map of the utility model.
Fig. 2 is described a kind of wind-force layering coal bunker control of the utility model and drive mechanism sketch map.
1, coal bunker main body; 2, coal guide plate; 3, star-like coal feeder; 4, coal flashboard; 5, coal sifter; 6, high-pressure air hose; 7, coal flashboard adjusting gear; 8, coal flashboard regulating handle; 9, bearing block; 10, travelling gear; 11, coal sifter regulating handle; 12, high-pressure blast storehouse flange; 13, inspection door.
The specific embodiment
Among the embodiment as shown in Figure 1, the described a kind of wind-force layering coal bunker of the utility model comprises coal bunker main body 1, star-like coal feeder 3 and coal flashboard 4; Be provided with coal guide plate 2 in the said coal bunker main body 1, said coal guide plate 2 ends are provided with star-like coal feeder 3, and said star-like coal feeder 3 tops are provided with coal flashboard 4; Said star-like coal feeder 3 is installed on the bearing block 9; On the said star-like coal feeder 3 travelling gear 10 is installed, said travelling gear 10 connects the boiler governing box, and said star-like coal feeder 3 belows are provided with coal sifter 5; Said coal sifter 5 belows are provided with high-pressure air hose 6, and said coal bunker main body 1 below is provided with fire grate.Said coal flashboard 4 connects coal flashboard adjusting gear 7, and said coal flashboard adjusting gear 7 connects coal flashboard regulating handle 8.Said high-pressure air hose 6 is connected with high pressure positive blower through high-pressure blast storehouse flange 12.Said coal bunker main body 1 lower end is provided with inspection door 13.
Coal charge is transported to wind-force layering coal bunker top by feed belt and drops in the coal bunker main body 1 during work; Coal charge slides into star-like coal feeder 3 places for 2 times along coal guide plate; Adjust distance control coal seam thickness according to required coal amount between star-like coal feeder 3 and the coal flashboard 4, coal charge drops on coal sifter 5 after through star- like coal feeder 3, and 5 pairs of coal charges of coal sifter sieve; The granule coal dust is fallen high-pressure air hose 6 outlets through coal sifter 5; Be blown into boiler furnace by high-pressure blast, fully burning immediately in burner hearth, bulky coal cinder is slipped to along the coal sifter and transports into through fire grate on the fire grate that boiler furnace burns; Because also bigger than the gap between the gathering coal, the wind that air blast is carried up can well pass top, arrival coal seam, coal seam and help coal cinder fully to burn.
