Abstract
The utility model relates to an automatic feeding and dust removing plugging-free burner for burning granular fuel, which belongs to the technical field of cooker part manufacture, and comprises a hole plate burning tank, a cooling chamber which is arranged at a fuel inlet end of the burning tank, an air inlet duct which is communicated with the cooling chamber below the burning tank, and a spiral feeding mechanism which penetrates through the cooling chamber to be fixedly connected with the fuel inlet end of the burning tank, wherein a plurality of through holes are arranged on a wall of a discharge end of the spiral feeding mechanism positioned in the cooling chamber. The utility model has the advantages that: the feeding method that the granular fuel at the back of the spiral feeding mechanism pushes the granular fuel at the front is used for the burning tank, and the ash formed after the fuel is burned is discharged out of the burning tank, thereby effectively preventing the plugging phenomenon; the cooling chamber between the spiral feeding mechanism and the burning tank and an air curtain formed at the discharge end of the spiral feeding mechanism ensure that the feeding mechanism is not burned out, and simultaneously prevent smoke and fire from moving in the opposite direction of feeding.
Description
Technical field
It is the burner of the combustion furnace use of fuel with the biomass energy particle that the utility model relates to a kind of.Belong to stove and accessory parts manufacturing technology field.
Background technology
Be that the burning of the combustion furnace of fuel mostly is by its screw feed mechanism granular fuel to be delivered to burner hearth at present, then on the grate of burner hearth bottom, burn by the fire rod igniting that is positioned on burner hearth under with these biomass energy particles such as wood substance grain, stalk particles.This is because biomass energy particle can form the very strong black dirt of a kind of deadlocked power behind high-temp combustion in the shortcoming one of burning on the grate, this black dirt be difficult to by under the grate in ash bucket, thereby very easily cause stifled thorax and stop working; The 2nd, the discharging opening of screw feed mechanism directly joins with burner hearth, the high temperature of the burner hearth granular fuel in the feed mechanism that often ignites, and the lighter makes the feed mechanism damage, and weight person also can be fired to hopper; The 3rd, an air intake of burner hearth is easy to make cigarette, fire to charging opposite direction play.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, and a kind of stifled burner of exempting from that stifled thorax phenomenon and automatic feed that causes feed mechanism to damage and ash discharge can not take place is provided.
The purpose of this utility model realizes by following technological means:
Automatic feed that a kind of wood grain fuel that burns is used and ash discharge exempt from stifled burner, it is characterized in that described burner by the orifice-plate type burning groove, be arranged on orifice-plate type burning groove fuel inlet end cooling chamber, be arranged on the air inlet duct that communicates with cooling chamber of orifice-plate type burning groove below and pass the screw feed mechanism that cooling chamber is fixed in burning groove fuel inlet end and constituted, the wall of discharge end that is arranged in the screw feed mechanism of cooling chamber is provided with some through holes.
During use this burner is placed the burner hearth below of combustion furnace, the ash hole of its burning groove is positioned at the ash bucket top of combustion furnace, and an ajutage of the cooling chamber of burner and combustion furnace joins.By screw feed mechanism granular fuel is delivered to the burning groove burning through cooling chamber, the flame that burning forms enters the burner hearth of top for using.The particle that burning in the burning groove fires under the effect of particle waiting of being advanced by screw feed mechanism, while burn towards the ash hole motion of burning groove, drops to the ash bucket from ash hole at last.Whole combustion process is dynamic process, and the burning quality height is less scaling, also is easy to discharge from ash hole even if form black dirt, thereby has avoided stifled thorax; An air intake part of wind pushing mechanism enters behind the air inlet duct of burning groove below hole by the orifice-plate type burning groove, and to blow to burning groove combustion-supporting; A part enters cooling chamber, works to stop the heat of burning groove, make particle in the feed mechanism unlikely fire burns, thereby guarantee that feed mechanism can not burn out.An air intake that enters into cooling chamber forms air curtain by the discharge end that through hole on the discharging end wall in cooling chamber enters into screw feed mechanism of stretching of screw feed mechanism, works to prevent that cigarette, fire are to charging opposite direction play.
The utility model advantage compared with prior art is granular fuel to be placed on the burning groove burn, replaced original grate, the feeding style that the granular fuel of the back of original screw feed mechanism is promoted the granular fuel of front is extended on the burning groove, promptly adopt the combustion system of material pusher, the black dirt that forms behind the fuel burning-out is arranged immediately from burning groove, has avoided stifled thorax phenomenon effectively; Be arranged on the cooling chamber between screw feed mechanism and the burning groove and the discharge end that the cold wind in the cooling chamber is introduced screw feed mechanism formed air curtain, guaranteed that feed mechanism can not burnt out and also prevented simultaneously that cigarette, fire are to charging play in the other direction.
Below in conjunction with drawings and Examples the utility model is described further.

The specific embodiment
Referring to Fig. 1～4, this automatic feed and ash discharge exempt from stifled burner by orifice-plate type burning groove 1, be arranged on orifice-plate type burning groove fuel inlet end cooling chamber 2, be arranged on the air inlet duct 3 that communicates with cooling chamber 2 of orifice-plate type burning groove below and pass the screw feed mechanism 4 that cooling chamber is fixed in burning groove fuel inlet end and constituted, the wall of discharge end that is arranged in the screw feed mechanism of cooling chamber is provided with some through holes 5.6 is the air inlet of cooling chamber among the figure, and 7 for connecting gusset, and 8 is the air vent of orifice-plate type burning groove, and 9 is the ash hole of burning groove.
Granular fuel is advanced in the burning groove 1 by screw feed mechanism 4 during work, while the granular fuel that entered later of burning is pushing away ash hole 9 motions towards burning groove, drops out from ash hole at last.Enter into cooling chamber 2 and air inlet duct 3 from an air intake of the wind pushing mechanism of stove from the air inlet 6 of cooling chamber, it is combustion-supporting that the air vent 8 that an air intake that enters into air inlet duct 3 passes orifice-plate type burning groove 1 enters into burning groove.Cooling chamber 2 plays cooling behind air intake heat insulation, make particle in the feed mechanism unlikely fire burns, thereby guarantee that feed mechanism can not burn out.An air intake that enters into cooling chamber 2 enters into the discharge end of screw feed mechanism by through hole 5.
Also can offer a fire rod mounting groove 11 in orifice-plate type burning groove bottom.The benefit of doing like this is to make the bottom of fire rod (not shown) and orifice-plate type burning groove 1 be in same plane, helps the horizontal sliding of granular fuel.Also can not establish this fire rod mounting groove, directly fire rod is placed on the bottom of orifice-plate type burning groove 1.
