Description
Technical field
The present invention relates to a kind of Novel wind layered coal feeder.
Background technology
Chain furnace coal feeder generally has two kinds of forms at present, a kind of is spreader feeder, by frame for movement continuous uniform coal is shed to stove, throwing in coal process adds hot blast to spray, form large coal particles under, fine particle coal is at upper hierarchy, it takes into account the advantage of grate firing and two kinds of modes of chamber combustion, and spreader feeder is only applicable does not have front and back arch or front and back to encircle the less chain furnace of coverage rate.Another kind is roll-type layered coal feeder, fire coal relies on deadweight to fall into coal moving roller from coal bunker, by stirring coal moving roller, make fire coal become loose, then fall into broach sifter, because large coal particles and small-particle coal fall into the asynchronism(-nization) of fire grate, thereby form large little layering under particle, it is simple in structure, cloth coal is smooth, Uniform Ventilation, but when coal-burning particle is even, fine coal is when more, roll-type layered coal feeder cannot, by effective layering, cause partial combustion incomplete.
In view of above situation, develop a kind of Novel wind layered coal feeder, take into account the advantage of air layered and roll-type layered coal feeder simultaneously and can adapt to various working, thereby the coal-fired layering of raising chain furnace and ventilation effect be both necessary also have higher promotional value.
Summary of the invention
The problem that the present invention solves is to provide a kind of Novel wind layered coal feeder, can make fire coal be evenly distributed on the fire grate of chain furnace, form large coal particles under, small-particle coal in, fine coal is at upper hierarchy, and can adapt to the variation of coal and coal grain, improves the ventilation effect in coal seam.
The invention provides following technical scheme and solve above technical problem:
This device comprises that one for stirring stirring coal roller (1), stirring the spillplate (2) below coal roller of broken wet coal, can control the arc coal flashboard (4) of coal breakage amount, coal moving roller I (3), coal moving roller II (6), the warm-air pipe (8) of introducing from the external world, warm-air pipe with spout, warm-air pipe spout faces coal passing plate (7), broach sifter (9) welded and installed on gear fume plate (10), places heat insulation foam (13) between face arch (5) and layered coal feeder.
The operating procedure of device is: coal enters air layered coal feeder through coal dropping port (11), by agitating roller (1), stir broken wet coal, prevent that coal adhesion from becoming piece to occur, the coal moving roller I (3) and the coal moving roller II (6) that fall its below make ature of coal become loose, regulate the height of arc coal flashboard (4) to reach the amount that enters coal moving roller II (6) of controlling; Hot blast in warm-air pipe (8) sprays from spout, fine coal is blown in the air channel of coal passing plate (7) and gear fume plate (10) composition, and finally drops on the top in coal seam; Particulate coal is fallen on the broach sifter (9) of below, because its gap is different, small-particle coal directly falls, and bulky grain rolls forward, so just formed large coal particles under, small-particle coal in, fine coal is at the layered effect of upper favourable ventilation, improved efficiency of combustion.
Adopt the air layered coal feeder of said structure, for different coals and coal grain, can regulate the flow velocity of hot blast, avoided roll-type layered coal feeder cannot carry out to fine coal the shortcoming of effective layering, hot blast can also play the coal-fired effect of drying simultaneously, fine coal drops on fire grate (12) above through air channel, not high with the required distance of fire grate (12) to face arch (5), needn't transform and just possess the good advantage of spreader feeder layered effect boiler front arch (5).
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention;
Fig. 2 is broach sifter phantom view of the present invention;
Fig. 3 is coal moving roller II phantom view of the present invention;
Fig. 4 is the coal roller perspective view that stirs of the present invention;

The specific embodiment
By reference to the accompanying drawings, describedly comprise that one for stirring stirring coal roller (1), stirring the spillplate (2) below coal roller of broken wet coal, can control the arc coal flashboard (4) of coal breakage amount, coal moving roller I (3), coal moving roller II (6), the warm-air pipe (8) of introducing from the external world, warm-air pipe with spout, warm-air pipe spout faces coal passing plate (7), broach sifter (9) welded and installed on gear fume plate (10), places heat insulation foam (13) between face arch (5) and layered coal feeder.
The operating procedure of device is: coal enters air layered coal feeder through coal dropping port (11), by agitating roller (1), stir broken wet coal, prevent that coal adhesion from becoming piece to occur, fall coal moving roller I (3) and the coal moving roller II (6) of its below, above it, there is the wavy tooth of projection can make ature of coal become loose, regulate the height of arc coal flashboard (4) to reach the amount that enters coal moving roller II (6) of controlling; Hot blast in warm-air pipe (8) sprays from spout, fine coal is blown in the air channel of coal passing plate (7) and gear fume plate (10) composition, when fine coal is more or particle hour can increase the flow velocity of warm-air pipe spout, stop fine coal to drop on broach sifter (9) above; Particulate coal is directly fallen on the broach sifter (9) of below, because its gap is different, small-particle coal directly falls, and bulky grain rolls forward, so just formed large coal particles under, small-particle coal in, fine coal is at the layered effect of upper favourable ventilation, improved efficiency of combustion.
Fire grate (12) is pressed certain gearratio by driving-chain and is driven coal moving roller I (3), coal moving roller II (6) to rotate constantly to fire grate (12) coal, stir coal roller (1) and be connected by chain with coal moving roller I (3) and obtain power, stir broken coal-fired.Between face arch (5) and air layered coal feeder, place heat insulation foam (13), prevent radiant heat damage coal feeder.
