Longitudinal centre line and boiler longitudinal centre line that the inside and outside axle sleeve 12,11 of automatics, interior axle 13, vertical shaft 15, fire-grating frame 18, umbrella shape go out slag pan 19, steel ball 16 and pressurized spill ball seat 17 are the same straight line perpendicular to ground.Outer shaft 11 is welded on down on the horizontal water tube of transverse water pipe bundle 2 bottoms, internal axle sleeve 12 is set in the outer shaft 11 and by bolting, interior axle 13 upper ends place in the internal axle sleeve 12, the lower end is fixed in the vertical shaft 15 by fixed bar 14, fire-grating frame 18 and be positioned at its following umbrella shape and go out slag pan and be welded on respectively on the vertical shaft 15 and and be fixedly welded on the vertical shaft 15 by gusset plate, be welded with four coil supports 28 on the fire-grating frame 18, every coil support is fixedly welded on the vertical shaft 15 by gusset plate respectively, have the groove 29 that surely closes mutually with fire grate segment 30 each fulcrum on every coil support, each circle on the big frame 18 all is covered with fan-shaped fire grate segment 30, be cast with ridge 33 on the fire grate segment 30, and on row's face, have a jack 31, the bar 20 that is obstructed is housed in the hole, have zigzag on the fire grate segment one end limit and leak ash-pit 32, drag strut 21 is positioned at fire-grating frame 18 times, and fixedly is installed on the inner bag 1, on the drag strut 21 turnbuckle can be housed.Umbrella shape goes out slag pan 19 peripheries the tooth 22 that is meshed with gear 23, and arc scum board 26 goes out slag pan 19 with umbrella shape and is the gap by dress, and fixing by being loaded on slag notch 27 1 sides.Surely close mutually with steel ball 16 on the stressed spill ball seat 17 that places ground vertical shaft 15 lower ends.
The utility model is when operate as normal, after decelerator 25 goes out tooth 22 engagements on the slag pan 19 by power transmission shaft 24 and gear 23 and umbrella shape, drive umbrella shape and go out slag pan 19 rotations, this moment, umbrella shape went out slag pan 19, fire-grating frame 18 is that the center of circle becomes horizontal circumferential running with vertical shaft 15, and internal axle sleeve 12 rubs by motion with interior axle 13,17 one-tenth slips of steel ball 16 and stressed spill ball seat.
After coal bunker places the combustion chamber, with pull hook 34 and draw ring 35 rectangle folded sheet 37 is fixed into the certain coal of leakage naturally width, back plate washer backboard is inserted in two inner wall grooves, fuel is dropped into the folding coal bunker 36 of preheating, fuel is behind preheating and drying, naturally drop on the fire grate segment 30 of fire-grating frame 18, when fire-grating frame 18 along the circumferential direction turns round, the fan-shaped fire grate segment 30 that is placed in the bracket groove 29 turns round thereupon, when the bar 20 that is obstructed in inserting fan-shaped fire grate segment jack 31 is being subjected to being positioned at the resistance of the drag strut 31 under the big frame 18, fan-shaped fire grate segment 30 beginning wings rise to ventilate and leak ash, movable fuel is gone up the effect that ridge [33] also plays brokenly burnt ventilation activity fuel simultaneously, when the bar 20 that is obstructed is thrown off with drag strut 21, fan-shaped fire grate segment 30 is got back to original level automatically and is produced vibration under the pressure of deadweight and fuel, another ventilates and leaks grey movable fuel, each unlatching vibration all leaves out by mistake the lime-ash of after-flame in umbrella shape to go out on the slag pan 19, every fan-shaped fire grate segment 30 so periodic unlatchings, close, make the lime-ash on the fire grate segment constantly leave out by mistake on the slag pan, the after-flame slag discharges out of the furnace through cleanout door 27 being subjected to placing the direction of fall that the resistance lower edge umbrella shape of arc scum board 26 of card upper end goes out slag pan 19 of slagging tap to walk to the plate edge of slagging tap.Burn away after remaining unburnt red lump coal and fresh fuel mixing, thereby with the whole after-flames of fuel.Flame that produces after fuel burns on fire grate and high-temperature flue gas pass through transverse water pipe bundle 2 and preceding perpendicular lower end of bending transverse water pipe bundle 4 down, under the restriction of the first guiding heated sheet 7, flue gas becomes horizontal direction to wash away each root horizontal water tube of transverse water pipe bundle 2 down, the dust that can not stop is except that in the combustion chamber, preceding perpendicular curved festoon 4, dedusting but laying dust not, the bottom of perpendicular curved water pipe and secondary blast mouth before unburnt high-temperature flue gas concentrates on (the secondary blast mouth is arranged 3-10), the air that enters burns away after mixing, and first backhaul is finished by the top that preceding perpendicular curved narrow orifice place, festoon 4 top enters transverse water pipe bundle 3 in the back.
The last transverse water pipe bundle 3 of bank of staggered pipes, under the guide effect of the first guiding heated sheet 7 and the second guiding heated sheet 9, flue gas is advanced downwards, and directly plays the deashing effect, and the dust that falls is behind the slope.Discharge to shoot door 8, flue gas enters the bottom of the perpendicular curved festoon 5 in back, finishes second backhaul.
Forward and backward perpendicular curved festoon 4,5 aligning methods are identical, act ons also identically, and perpendicular curved festoon 5 bottoms upwards become low-temperature flue gas to flue gas from the back, and through impact tube 10, chimney enters atmosphere, and the dust that falls is finished the 3rd backhaul through shoot door 8 discharges.
If the utility model removes second guiding heated sheet 9 and the automatics with the end socket top seal, loads onto fixed cast-iron fire grate in the boiler body bottom, can become the two return miniature boiler.
