Description

The stalk particle burning stove feed arrangement

Technical field

The utility model relates to a kind of feed arrangement, specifically a kind of stalk particle burning stove feed arrangement.

Background technology

Stalk is left cauline leaf or the tendril of the product of various crops in agricultural products.In recent years, due to crop straw burning, particularly the stalk of agricultural leftover is incinerated as rubbish, environment has been caused seriously influence, and a large amount of remaining stalks do not obtain rational development and utilization.

Scientific and technological development along with China's industry in recent years, the energy, electric power, research finds that stalk resource is abundant, recyclability is strong, the utilization of stalk not only can be alleviated the nervous situation of the energy, electricity supply and demand, also helps the biomass resource that improves environment and reasonably utilize sustainable development.Living beings are the fourth-largest energy that is only second to coal, oil, natural gas, account for 14% in the world energy sources aggregate consumption.The annual crop stalk stock number of China account for the Biomass Energy Resources amount near half, the stalk using energy source is one of main path of agricultural crop straw comprehensive utilization.

Stalk is cut up with a hay cutter into cun a high temperature granulating after section, make its density reach 1.0 1 1.2 water content 10 one 13%, caloric value 3,800 one 4500 kilocalorie/kilograms.Can be directly as Industrial Boiler fuel and domestic fuel.Stalk granular fuel is not only easily lighted, and flame is vigorous, and flare is stable, and the nuisance such as sulfur-bearing and phosphorus not in flue gas, and ashes can also be done the plant ash raw material.

Northern area in China has had some peasant households to adopt the stalk particle material to replace traditional fuel such as coal and timber as warming and life fuel at present, what be complementary with it is that some producers also develop some in succession for small home boiler and the warming stove of stalk particle material, but because also there are some irrational places in its structure, particularly there is no good supporting charging charging gear, so people need manually add granular fuel in use, automaticity is low, waste time and energy, labour intensity is large, contaminated environment.

Summary of the invention

The purpose of this utility model be to provide a kind of simple and reasonable, easy to use, time saving and energy saving, labour intensity, combustion efficiency that can alleviate the operator are good, smoke dust contaminated environment, stalk particle material combustion furnace feed arrangement that automaticity is high.

The purpose of this utility model is to realize like this, this feed arrangement comprises frame, be arranged on the trapezoidal hopper of frame upper end, be arranged on the pusher auger of discharge port end below trapezoidal hopper, the reducing motor that connects pusher auger one end, the drainage conduit that is connected to the pusher auger other end, the blower fan that is arranged on the frame bottom, connecting fan be with the air duct of outlet air end, described outlet air end is a tubular structure that an end blocks, perpendicular to the air duct setting, on it with a plurality of exhaust vents.

The periphery of described frame is provided with housing, is provided with the time switch and the time switch of controlling reducing motor of control blower fan in a side of housing.

The utility model is owing to adopting said structure to make the stalk particle material to be added in combustion furnace by automatic powder adding, feed and feeding quantity are accurately controlled, have that advantages of simple, labour intensity, combustion efficiency easy to use, time saving and energy saving, that can alleviate the operator are good, a smoke dust contaminated environment, automaticity advantages of higher.

The specific embodiment

Shown in accompanying drawing 1,2: this feed arrangement comprises frame 1, be arranged on the trapezoidal hopper 2 of frame 1 upper end, be arranged on the pusher auger 3 of discharge port ends below trapezoidal hopper 2, the reducing motor 4 that connects pusher auger 3 one ends, the drainage conduit 5 that is connected to pusher auger 3 other ends, the blower fan 6 that is arranged on frame 1 bottom, connecting fan 6 be with the air duct 8 of outlet air end 7, described outlet air end 7 is the tubular structures that an end blocks, arrange perpendicular to air duct 8, on it with a plurality of exhaust vents 9.

Shown in accompanying drawing 3: the periphery of described frame 1 is provided with housing 10, is provided with the time switch 11 and the time switch 12 of controlling reducing motor 4 of control blower fan 6 in a side of housing 10.

Operation principle:

During use, the stalk particle material is put into trapezoidal hopper 2, set the start-up time of reducing motor 4 and blower fan 6 according to actual conditions, reducing motor 4 starts will drive 3 rotations of pusher auger, and the stalk particle material is advanced to drainage conduit 5 through pusher auger 3 and enters combustion furnace 13; Blower fan 6 starts, and wind will be entered outlet air end 7 and be entered combustion furnace 13 bottom oxygen-supplying combustion-supportings through a plurality of exhaust vents 9 on it by air duct 8.
