Description
Technical field
The invention belongs to field of mechanical technique, relate to the feed mechanism of a kind of feed mechanism, particularly boiler.
Background technology
The current energy is nervous gradually, and coal, oil, Gas Prices are high gradually.And this three large energy to belong to the disposable energy non-renewable, therefore it is imperative to explore regenerative resource.According to the requirement of the People's Republic of China's " Renewable Energy Law ", National Development and Reform Committee in August, 2006 tissue worked out " planning of regenerative resource Long-and Medium-term Development ", propose the developing goals to the year two thousand twenty regenerative resource in 2010 and task, wherein, biomass solid formed fuel reaches 1,000,000 tons and 5,000 ten thousand tons respectively, and establishes the status of biomass solid formed fuel as modern clean energy resource.
Succeeding in developing of biomass boiler thoroughly solve this problem, but new problem put again in face of, biomass boiler divides two kinds, and a kind of is the compressing particle of burning, and this kind of fuel density is large, and frictional force can directly enter hearth combustion with traveling-grate stoker greatly; The another kind of boiler for burning bulk cargo, this kind of volume of fuel is large, and density is little, can not produce enough large frictional force, causes fuel to be deposited in hopper and can not enter burner hearth with fire grate, and boiler can not normally be run.Because pressing cost saved by burning bulk cargo, so just greatly reduce the operating cost of boiler, so it is extremely urgent to solve boiler feeds problem.
Its publication number of Chinese patent CN202546802U discloses a kind of boiler and injection type pay-off thereof.The injection type pay-off of above-mentioned patent comprises air blast, also comprises the injection type feed pipe be connected with the air outlet of described air blast, and the air outlet of described injection type feed pipe is used for communicating with the burner hearth of boiler.
The injection type pay-off that above-mentioned patent provides, biomass fuel is from the charge door of boiler or top even drop down, open air blast, fuel is sucked burner hearth by the ejector action of the high-pressure blast that injection type feed pipe sends by fuel, changed the size of airflow pressure by the load of boiler oil consumption and boiler, ensure boiler normal combustion and operation.
But above-mentioned patent can be burnt bulk cargo, has therefore saved pressing cost, has so just greatly reduced the operating cost of boiler, so solve the extremely urgent feeding problems of boiler.But injection type feed pipe structure is too complicated, cause its processing difficulties and cost compare is high.
Summary of the invention
The object of the invention is the problems referred to above existed for prior art, provide a kind of feeding stability high and the feed mechanism of the boiler of compact conformation.
Object of the present invention realizes by following technical proposal:
A kind of feed mechanism of boiler, boiler have charging aperture and the fire grate for transfer the fuel, above-mentioned charging aperture is positioned at fire grate top, it is characterized in that, mechanism is arranged between the charging aperture of boiler and fire grate, comprises hopper and feeding material component, above-mentioned hopper is positioned at and is connected with charging aperture, described feeding material component comprises feed pipe and blower fan, and air outlet and feed pipe the inner of described blower fan are connected, and the outer end of described feed pipe is between charging aperture and fire grate.
