Abstract
The utility model discloses a feeding device of a chain grate boiler for combusting biomass particles. The feeding device comprises a stock bin in front of the boiler, the stock bin in front of the boiler is installed on a support of the stock bin in front of the boiler, an inner hopper is installed in the stock bin in front of the boiler and connected with a discharging pipe, the discharging pipe is connected with a feeding pipe of a combustion chamber, a separation hopper is installed in the stock bin in front of the boiler, a rotating barrel is installed below a separation hopper opening, racks are installed on the outer wall of the rotating barrel, a speed reducer is connected to the exterior of the rotating barrel, and the speed reducer is connected with a speed adjusting motor. The feeding device has the advantages that biomass particles in the stock bin are separated from a discharging channel; the feeding quantity of the feeding device is adjustable; little heat can enter a feeding channel from the combustion chamber; the biomass particles can be evenly laid on a boiler grate when the biomass particles enter the combustion chamber.
Description
Technical field
The utility model relates to a kind of charging gear of burning biomass particle chain grate boiler.
Background technology
The mankind are being faced with global warming, depletion of the ozone layer, the series of problems such as acid rain, haze, and a host of facts and data show, coal-burning boiler is main pollution sources.The operating cost of oil-burning gas-fired boiler is quite high again, and petroleum resources is non-renewable resources.By discarded agricultural crop straw, rice husk, wood sawdust, yule logs, through being processed into particle, as the fuel of boiler, this is to alleviating environmental pollution, and Optimization of Energy Structure, maintains sustainable economic development significant.The biological particles material key of burning safely and reliably on traveling-grate stoker is: 1, biological particles material not spontaneous combustion in feed bin, 2, charging is unimpeded, and inlet amount is adjustable, 3, allow and enter biological particles material uniform spreading in burner hearth on fire grate.
Utility model content
The purpose of this utility model is to provide one, and for burning biomass particle chain grate boiler provides, one is safe, adjustable biological particles charging gear.
The technical solution of the utility model is, a kind of charging gear of burning biomass particle chain grate boiler, comprise stokehold feed bin, stokehold feed bin is contained on ladle addition bin bracket, in the feed bin of stokehold, has internal conflict, conflicts internally and connects material blanking tube, material blanking tube connects burner hearth feed pipe, in the feed bin of stokehold, there is the bucket of partition, below cutting off bucket quarrel, have rotating cylinder, on rotating cylinder outer wall, have tooth bar, the external reductor of rotating cylinder, reductor connects buncher.
Be provided with charging airduct at material blanking tube downside.
Burner hearth feed pipe is the flat necking pipe of inside reducing.
In burner hearth feed pipe, there is deflector.
The utlity model has following technique effect, 1, biological particles material and blanking channel in feed bin separate.2, the feeding coal of charging gear is adjustable.3, from burner hearth, enter the heat of feeder channel few.4, when biological particles material enters burner hearth, can be layered on equably on fire grate.
Brief description of the drawings
Fig. 1 is cross section view of the present utility model.
Fig. 2 is top view of the present utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of charging gear of burning biomass particle chain grate boiler, on the burner hearth feed pipe 9 of burning biomass particle chain grate boiler 11, stokehold feed bin 1 is housed, stokehold feed bin 1 is contained on ladle addition bin bracket 7, in stokehold feed bin 1 to be had and conflicts internally 4, internal conflict 4 connects material blanking tube 5, material blanking tube 5 connects burner hearth feed pipe 9, in stokehold feed bin 1, there is the bucket of partition 2, below cutting off bucket 2 quarrels, there is rotating cylinder 3, on rotating cylinder 3 outer walls, there is tooth bar 12, the external reductor 13 of rotating cylinder 3, reductor 13 connects buncher 14; Be provided with charging airduct 6 at material blanking tube 5 downsides; The flat necking pipe that burner hearth feed pipe 9 is inside reducing; In burner hearth feed pipe 9, there is deflector 8.Biomass granule fuel is contained in stokehold feed bin 1, regulates feeding coal by the partition 2 below rotating cylinders 3 that struggle against, and when biomass granule fuel enters burner hearth, can be layered on equably on fire grate 10
