The feeding manner of inventor to boiler conducts in-depth research, in any case find to change charging aperture, capital is because the problem of particle gravity, be difficult to realize uniform distribution, overcoming gravity to particulate material falls on distant fire grate, then must apply external force, and simple motive force still can make particulate material concentrate on the fire grate of certain, and be difficult to realize even diffusion.Inventor is for the problems referred to above, devise a kind of spreading reel, particulate material is sent on spreading reel, utilize the High Rotation Speed of spreading reel that particulate material is shed in boiler along charging aperture under the influence of centrifugal force, this strength can be good at the gravity overcoming particulate material self, and this centrifugal force can make particulate material evenly spread, partial particulate material can evenly be sprinkling upon on the fire grate of boiler, also has partial particulate material when being shed to the fire grate superjacent air space of burner hearth just by ignition combustion, be equivalent to Boiling Combustion, under Boiling Combustion state, fuel can fully burn, improve fuel efficiency.
Further, spreading reel is disposed radially a point muscle, spreading reel is separated into storage tank one by one, be convenient to the collection of particulate material, transmit and shed, the diameter of described spreading reel should be less than feed pipe caliber, enable spreading reel in pipe with the axle center of wheel shaft for center of circle fast rotational, the space of throwing around loose wheel and between feed pipe can be thrown in space to avoid particulate material when spreading reel rotates by fill insulant material as required, and be burner hearth insulation, reduce heat energy loss.The diameter of preferred described spreading reel is less than the caliber 1-3cm of feed pipe.
Described spreading reel is driven by its wheel shaft, described wheel shaft is driven by drive unit by transmission mechanism, further, described drive unit can be the driving mechanism of design separately, also a drive unit can be shared with feeding device, as the driving shaft of the wheel shaft of spreading reel and the drive unit of feeding device coupled together by transmission mechanism (as belt or gear), the advantage of such design is save other a set of driving mechanism on the one hand, can synchronously drive spreading reel to rotate during feeding device work simultaneously, both can collaborative work.Because spreading reel needs to realize High Rotation Speed, and the rotating speed of the driving shaft that the motor of feed arrangement is drawn is lower, for solving this problem, the diameter ratio of the drive pulley of adjustable both connections and negative pulley wheel (or driving gear and driven gear), spreading reel is made to realize High Rotation Speed, without the need to increasing power separately.Described feeding device can be that existing various feed mechanism is as screw feeding machine etc.
Structure of the present invention is very simple, simple to operate, can realize evenly shedding graininess particulate material, particulate material is distributed on fire grate more even, abundant in burner hearth combustion, furnace flame is more even, each several part is by all consistent, and the thermal efficiency meets design requirement, and more traditional feeding manner can fuel saving more than 15%.The present invention is applicable to coordinating with various feeding device, for carrying particulate material in boiler.
