The fuel feeding device of the biomass boiler is simple in structure and can perform feeding automatically and continuously, so that the defect of low thermal energy of biomass fuel is overcome; unique auger pushing type feeding is adopted, residues can be removed automatically when lower fuel is pushed in, and influence on the firing effect due to hearth slagging is avoided; the auger feeding structure is simple and reliable in operation; and the feeding port can be closed by a turntable structure arranged at the feeding port when the auger stops work, and the flame is prevented from spreading to the auger and the fuel bin.
Description
Technical field
The utility model relates to a kind of boiler-burner, specifically a kind of biomass boiler fuel delivery means.
Background technology
Biomass fuel refers to that general main is the agriculture and forestry organic waste materials such as stalk, sawdust, bagasse, rice chaff using biological material burning as fuel, and the main distinction is in fossil fuel.The application of biomass fuel, reality is mainly biomass molding fuel, is using agricultural refuse as raw material, through techniques such as pulverizing, mixing, extruding, oven dry, make various moulding (as bulk, graininess etc.), a kind of Novel clean-fuel that can directly burn.The features such as that biomass fuel has is renewable, clean environment firendly, but also there is the unfavorable factors such as heat energy is low, consumption is large, burning velocity is slow, easy slagging scorification simultaneously, what existing boiler oil feedway had cannot continuous feeding, can not be for biomass fuel, although what have can continuous feeding, but due to poor reliability, long-time continuous operation troubles rate is high, and these unfavorable factors have all limited the extensive use of biomass fuel.
Summary of the invention
The utility model for address the above problem provide a kind of simple in structure, reliable, can Automatic continuous feed, the biomass boiler fuel delivery means of self-skimming, for popularization and the use of biomass fuel are provided convenience.
For achieving the above object, the utility model adopts following technical scheme:
Biomass boiler fuel delivery means described in the utility model comprises combustion chamber and Bunker, the lower end of described combustion chamber is provided with charging aperture, the lower end of Bunker is provided with discharging opening, the upper end of the auger being obliquely installed connects charging aperture, the upper end of the feed pipe being obliquely installed is fixedly connected on discharging opening, the lower end of described feed pipe is connected to the stage casing of auger, the lower end fixed installation turbine of described auger axis, and feeding motor is connected with worm gear drive by worm screw.
The lower end of described combustion chamber is provided with rotating disk, and described rotating disk is provided with the through hole matching with charging aperture, and the rotary tray motor and the described rotating disk that are fixedly mounted on the lower end of combustion chamber are in transmission connection.
Described combustion chamber is the sandwich consisting of inner and outer wall, and described rotating disk is arranged in the interlayer between described inner and outer wall, and described inwall is provided with air vent, and the interlayer of described combustion chamber is communicated with air blast by air channel.
Owing to having adopted said structure, this biomass boiler fuel delivery means is simple in structure, can Automatic continuous feed, makes up the defect that biomass fuel heat energy is low; Adopt unique auger push mode feed, when the fuel of below advances, can automatically remove residue, avoid Boiler Furnace slagging to affect combustion efficiency.Auger feeding structure is simple, reliable; The turntable structure that is arranged on charging aperture can seal charging aperture when auger is out-of-work, avoids propagation of flame in auger and Bunker.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of rotating disk.
The specific embodiment
As shown in Fig. 1, figure, biomass boiler fuel delivery means described in the utility model comprises combustion chamber 1 and Bunker 2, the lower end of described combustion chamber 1 is provided with charging aperture, the lower end of Bunker 2 is provided with discharging opening, the upper end of the auger 3 being obliquely installed connects charging aperture, the upper end of the feed pipe 4 being obliquely installed is fixedly connected on discharging opening, and the lower end of described feed pipe 4 is connected to the stage casing of auger 3, and auger 3 is connected with feed pipe 4 is Y-shaped.The lower end fixed installation turbine 5 of described auger 3 axis, feeding motor 6 is in transmission connection by worm screw and turbine 5.In the time of 6 work of feeding motor, by worm screw, drive turbine and auger 3 rotations, just biomass fuel can be transported to eminence from lower, and send in the inner chamber of combustion chamber by the charging aperture of 1 lower end, combustion chamber.
The lower end of described combustion chamber 1 is provided with rotating disk 7, and as shown in Figure 2, described rotating disk 7 is provided with the through hole 8 matching with charging aperture, and the rotary tray motor 9 that is fixedly mounted on the lower end of combustion chamber 1 is in transmission connection with described rotating disk 7.Rotary tray motor 9 is by control circuit and the 6 realization interlocks of feeding motor, and in the time of 6 work of feeding motor, rotary tray motor 9 drives rotating disks 7 rotations that through hole 8 is docked with charging aperture, opens the passage of auger 3 and charging aperture, and biomass fuel can enter combustion chamber smoothly; When feeding motor 6 stops, rotary tray motor 9 drives rotating disk 7 Rotate 180 degree, and through hole 8 and charging aperture are staggered, and rotating disk 7, by the pathway closure between auger 3 and charging aperture, can prevent that the flame in combustion chamber from spreading in auger downwards like this.
Described combustion chamber 1 is the sandwich consisting of inner and outer wall, and described rotating disk 7 is arranged in the interlayer between described inner and outer wall, and described inwall is provided with air vent 10, and the interlayer of described combustion chamber 1 is communicated with air blast 11 by air channel.Air blast 11 is dried in combustion chamber by air vent 10, contributes to the abundant burning of fuel and reduces smoke contamination.
Fuel in combustion chamber 1 takes fire from top layer, and along with the burning of top layer fuel, the fuel of below rises top layer fuel is disperseed to back down, and fuel burns under the state constantly stirring, and can improve efficiency of combustion and can prevent that again fuel is because of static combustion slagging scorification.
