Abstract
The invention discloses a novel rotary air-cooled grate system for a biomass boiler, which comprises a rotating shaft (1), a grate chassis (4), a chassis bracket (5), a grate (6), a primary air duct (7), an air duct bracket (8), a wind deflector (9), a belt pulley (10), a belt (11) and a motor (12). The novel rotary air-cooled grate system for the biomass boiler is characterized in that the rotating shaft (1) rotates to drive the grate (6) to rotate; and air enters the primary air duct (7) through the wind deflector (9) and is uniformly blown towards the grate (6), so that the fuel on the grate is combusted. The novel rotary air-cooled grate system for the biomass boiler has the advantages that firslty, a variable-speed gear can be manually adjusted, so that the grate is low and uniform in rotating speed, and the fuel is uniformly arranged on the grate and is fully combusted; secondly, the shaft and the bearing are cooled by the air, and the self-temperature is effectively reduced, so that the primary air temperature is raised, and the fuel is conveniently combusted; and thirdly, the air supply temperature is changed through the wind deflector, so that the primary air is uniformly blown to the grate; and therefore, the grate is cooled, and the phenomenon that the biomass ash drops on the bearing so as to damage the shaft and accessories is avoided.
Description
Technical field
The invention belongs to mechanical field, relate to a kind of fire grate system of biomass hot water boiler, particularly the circular rotating fire grate system.
Background technology
The boiler that utilizes at present the biomass moulding briquetting to make fuel begins entering industrial market.The small-sized biomass boiler generally adopts fixed grate, because biomass fuel heat is low, per hour fuel consumption is more than the twice of coal, therefore require grate area larger, this is so that fuel is difficult to evenly pounce on fire grate, and therefore, the Novel fire grate structure of design biomass boiler is imperative.
The ventilation rate of existing living beings fixed grate is low, lime-ash does not drop easily, so that the shortcoming such as coking is serious, thickness of feed layer is inhomogeneous, fuel combustion is insufficient.Chinese patent application number is that 201120496356 patent (rotary fire grate) specification discloses a kind of biomass boiler rotary fire grate.Although this fire grate is evenly distributed on the fire grate fuel, one time the wind air feed is inhomogeneous, and fuel combustion is still insufficient, and the long-time running rotating shaft is very easily damaged under stress and high temperature action.
Summary of the invention
For above deficiency, the object of the present invention is to provide a kind of novel biomass boiler rotary wind black furnace heat-extraction system, by to rotary fire grate device shape and structure Renewal Design, make the boiler bed of material evenly be tiled on the grate surface, fuel is fully mixed with air, burning makes slag in time drop to below the grate surface fully simultaneously; By changing the wind wind direction one time, make a wind not only evenly blow to grate surface, protect simultaneously rotating shaft, prevent the high temperature damage.
Technical scheme of the present invention is achieved in the following ways: novel biomass boiler rotary wind black furnace heat-extraction system, comprise rotating shaft 1, fire grate botton plate 4, chassis overhang 5, fire grate 6, airduct 7, support of duct 8, deep bead 9, belt pulley 10, belt 11 and a motor 12
The upper end of rotating shaft 1 is connected with motor 12 by belt pulley 10, belt, be connected with airduct 7 one time, the rotating shaft lower end is fixed with the connection fire grate and can rotates together, fire grate is enclosed within airduct 7, one time there is a deep bead 9 in airduct 7 exits, the middle part of rotating shaft 1 is provided with chassis overhang 5 and fire grate botton plate 4 by bearing block 3, it is characterized in that: described rotating shaft 1 rotation, driving fire grate rotates together, wind enters airduct 7 by deep bead 9 and evenly blows out to fire grate, makes the fuel combustion on it.
Structure of the present invention: the one, because the boiler grate system can rotate, lime-ash in time drops to below the fire grate, prevents that slag from dropping in the airduct, fuel is mixed more even with wind, burns more abundant; Two is that a wind not only evenly blows to fire grate, improves simultaneously the rotating shaft heat radiation, effectively protects rotating shaft.
Description of drawings
Fig. 1: a kind of structural representation of the present invention.
Among the figure: 1 rotating shaft, 2 bearings, 3 bearing blocks, 4 fire grate botton plates, 5 chassis overhangs, 6 fire grates, 7 airducts, 8 support of ducts, 9 deep beads, 10 belt pulleys, 11 belts, 12 motors.
The specific embodiment
As shown in Figure 1, a kind of novel biomass hot-water boiler rotary wind black furnace heat-extraction system of the present invention comprises 1 rotating shaft, 2 bearings, 3 bearing blocks, 4 fire grate botton plates, 5 chassis overhangs, 6 fire grates, 7 airducts, support of duct 8, deep bead 9, belt pulley 10, belt 11, motor 12.The upper end of rotating shaft 1 is connected with motor 12 by belt pulley 10, belt, be connected with airduct 7 one time, the rotating shaft lower end is fixed with the connection fire grate and can rotates together, fire grate is enclosed within airduct 7, and one time there is a deep bead 9 in airduct 7 exits, and the middle part of rotating shaft 1 is provided with chassis overhang 5 and fire grate botton plate 4 by bearing block 3 and bearing 2, rotating shaft 1 rotation, drive fire grate and rotate together, wind enters airduct 7 by deep bead 9 and evenly blows out to fire grate, makes the fuel combustion on it.
When fire grate normally moves, motor 12 passes to fire grate 6 by belt 11 with energy with energy, makes its rotation, and one time wind makes progress to fire grate 6 bottom right on every side from rotating shaft 1, a uniform wind blows out all around from fire grate 6 bottoms under the effect of deep bead 9, and solid fuel is fully burnt.Because one time wind is supplied with by the fire grate bottom, like this so that rotating shaft temperature under a wind effect is very low all the time, purpose is to prevent and protect the damage of rotating shaft high temperature.
