At present, in order to solve the coking problem of biomass solid fuel, some burner arranges fire grate on grate, to solve the coking problem of biomass solid fuel; But this fire grate complex structure, installation inconvenience, the problem effect solving coking is also undesirable.
Utility model content
The purpose of this utility model is to provide a kind of rotary wind type grate combustion mechanism, this mechanism adopts the grate of rotary wind type, make biomass solid fuel Thorough combustion, and the lime-ash fired is when rotor wing rotation, pushed away in the bottom ash box hung and drop to bottom lower combustion chamber by rotor, thus solve the problem of biomass solid fuel coking; And this mechanism structure is simple, cost is low, easy to maintenance.
The utility model realizes the technical scheme that its object adopts:
A kind of rotary wind type grate combustion mechanism, comprises the grate in lower combustion chamber, lower combustion chamber, wherein:
Described grate comprises rotor, and there is the rotor shaft perpendicular to rotor face at the center of rotor, and rotor shaft is connected with driven gear through connecting rod, and described driven gear engages with the travelling gear on horizontal power transmission shaft;
Described connecting rod is equipped with sleeve pipe, and the two ends of sleeve pipe are provided with bracing frame;
Described lower combustion chamber is hollow cylindrical, the center line of grate and the center superposition of lower combustion chamber;
The diameter of described rotor is greater than the diameter of bracing frame.
Like this, during rotor wing rotation on grate, the lime-ash fired, just can be pushed away by the rotor rotated in the bottom ash box hanging and drop to bottom lower combustion chamber, avoid in burner hearth or lower combustion chamber generation coking.
Above-mentioned rotor is plural flight, and described flight is not in one plane and there is difference in height each other.Due to flight rotor not in one plane, and there is difference in height, during rotor wing rotation, the lime-ash fired, just can be pushed away by the rotor rotated and hang and drop in the bottom ash box bottom combustion chamber from the gap of upper and lower rotor, more be the reduction of the generation of coking.
Above-mentioned bracing frame comprises the back shaft be enclosed within sleeve pipe, and support bar connected vertically with back shaft.Like this, support grate better and rotate, good stability.
Above-mentioned driven gear, travelling gear are bevel gear.Such bevel gear polarization is good, Anti-moving, transmission effect are good.
Compared with prior art, the beneficial effects of the utility model are:
(1), the utility model can by the comburant of larger particles shape or imperfect combustion fuel barrier in lower combustion chamber, hole on rotor ventilates and supports, allow biomass solid fuel burn completely especially, greatly reduce the problem of coking, improve the combustion rate of combustion mechanism.
(2), grate of the present utility model, support frame structure be simple, installs also simple and convenient, also replaceable; Its cost is also cheap.
The course of work of the present utility model is:
After power transmission shaft end obtains power by handle or motor, the travelling gear be connected on power transmission shaft drives driven gear, and driven gear drives rotor shaft to rotate, and is linked in the connecting rod in rotor shaft, bracing frame also along with rotation; Burned lime-ash drops on rotor, due to flight rotor not in one plane, and there is difference in height each other, during rotor wing rotation, the lime-ash fired, just can be pushed away by the rotor rotated and hang and drop to from the gap of upper and lower rotor in the bottom ash box bottom combustion chamber.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
