Description

A kind of efficient straw burner

Technical field

The utility model is related to environmental technology field more particularly to a kind of efficient straw burners.

Background technology

In recent years, agricultural crop straw becomes the new source of Rural Plane Source Pollution.The annual summer harvest and when the autumn and winter, always has a large amount of The stalks such as wheat, corn burned in field, produce a large amount of heavy smogs, the bottleneck for not only becoming rural environmental protection is asked Topic, or even as bringing disaster to the arch-criminal of urban environment.

Stalk imperfect combustion will produce the pernicious gases such as a large amount of pellet and CO, seriously endanger environment and The health of people.The especially moist incomplete reason of straw burning of stalk fuel is mainly that fuel particle is too big, burning Time insufficient either ash content is too big to make burning velocity slow down or excess moisture, causes amount of smoke big.

Therefore, the environmental pollution that burning straw is brought has become a urgent problem to be solved.

Utility model content

In view of the above shortcomings of the prior art, the utility model provides a kind of efficient straw burner, this practicality is new Type by smoke pipe to furnace body outside stalk heated in advance, can burn faster after making it into combustion chamber, and in furnace body Smoke pipe it is also spiral, burning can be kept more abundant persistently to being heated in furnace body.

Technical solution adopted by the utility model to solve its technical problems is：

A kind of efficient straw burner, including furnace body, fire grate, air inlet pipe, smoke pipe, air blower, filter device and charging Slot, the furnace interior are combustion chamber, and the fire grate is horizontally set in furnace body at the position of lower end, and the air blower is logical Cross air inlet pipe to be connected to furnace body, and connectivity part is located at fire grate lower end, the feed well pass through after furnace body wall with combustion chamber, and The end of feed well is located at the top of fire grate, and the air inlet of the smoke pipe is fixed on furnace body inside, and is located at combustion chamber upper end, cigarette Pipe is spiral after furnace body to be sleeved on feed well, and the filter device includes cylinder, filter screen and wet sponge, the Mare Humorum Tender filter screen is respectively provided at the head end of cylinder, and the end of cylinder is connect with smoke pipe gas outlet.

Further, the fire grate is obliquely installed.

Further, it is hinged with a baffle in the head end of the feed well.

Further, the smoke pipe is spirally distributed in furnace body.

Further, it is equipped with internal thread in the cylinder ends, external screw thread, pipe is equipped on the outside of the smoke pipe gas outlet It is threadedly coupled with smoke pipe gas outlet.

Further, it is equipped with idler wheel in the furnace body lower end.

The utility model has the beneficial effects that：

1. by being nested with spiral helicine smoke pipe outside feed well, using the temperature of the exhaust gas after burning to the straw in feed well Stalk preheats, and avoids insufficient problem of burning caused by stalk humidity is thrown into behind combustion chamber.

2. since the smoke pipe in furnace body is also helical form, on the basis of carrying out continuing heat preservation, heating in furnace body, also may be used So that ash content decomposes, the content of solid particle in pollutant is reduced, pollution is reduced.

3. easy to disassemble to carry out subsequent cleaning and repair since filter device is threadedly coupled with smoke pipe.

The utility model by smoke pipe to furnace body outside stalk heated in advance, making it into behind combustion chamber can be faster Burning, and the smoke pipe in furnace body is also spiral, can continue the decomposition for accelerating ash content, significantly reduce pollution particle Discharge.

Description of the drawings

Specific implementation mode

The utility model in order to better understand explains in detail the embodiment of the utility model below in conjunction with the accompanying drawings.

As shown in attached drawing 1 to attached drawing 3, including furnace body 1, fire grate 2, air inlet pipe 3, smoke pipe 6, air blower 4, filter device and into Hopper 5 is equipped with idler wheel 9 in 1 lower end of furnace body, is moved easily, and 1 inside of furnace body is combustion chamber, and fire grate 2 is horizontally set in furnace body 1 At the position of lower end, air blower 4 is connected to by air inlet pipe 3 with furnace body 1, and connectivity part is located at 2 lower end of fire grate, ensure that combustion Indoor air capacity is burnt, allows burning more fully effectively.

Feed well 5 is passed through with combustion chamber after 1 wall of furnace body, and the end of feed well 5 is located at the top of fire grate 2, facilitates After stalk puts into furnace body 1 by feed well 5, directly falls on fire grate 2 and burn.In order to avoid stalk ashes are deposited in charging Slot lower end, fire grate 2 are obliquely installed.

The air inlet of smoke pipe 6 is fixed on 1 inside of furnace body, and is located at combustion chamber upper end, and smoke pipe 6 is after furnace body 1 at spiral Shape is sleeved on feed well 5, is preheated to the stalk in feed well 5 using the temperature of the exhaust gas after burning, is avoided because of stalk tide It is wet throw into behind combustion chamber caused by burn insufficient problem；Smog is escaped from feed well 5 in order to prevent, in the head of feed well 5 End is hinged with a baffle 8.

Filter device includes cylinder 71, filter screen 72 and wet sponge 73, and filter screen 72 and wet sponge 73 are distinguished from inside to outside Being fixed on the head end of cylinder 71, (in the present embodiment, filter screen 72 is sleeved on 71 outer end of cylinder and is fixed by rope yarn, wet sponge 73 It is fixed on filter screen 72 by viscose glue mode), the end of cylinder 71 is connect with 6 gas outlet of smoke pipe, in furnace body 1 after burning Smog is discharged by 6 gas outlet of smoke pipe, by filter screen 72 filters out bulky grain, wet sponge 73 filters out part toxic gas After be discharged into air, be effectively reduced pollution.In order to avoid filter device is for a long time using blocking, at 71 end of cylinder End is equipped with internal thread, and external screw thread is equipped on the outside of 6 gas outlet of smoke pipe, and pipe is threadedly coupled with 6 gas outlet of smoke pipe, and dismounting is flexible, Conveniently subsequently to the cleaning of filter device.

In order to solve the problems, such as that ash content is excessive in the gas after burning, smoke pipe 6 is also spirally distributed in furnace body 1, is held Continuous high-temperature heating, can be such that ash content decomposes, and reduce the content of solid particle in pollutant, reduce pollution, and can also be to stove It is carried out in body 1 on the basis of continuing heat preservation, heating, increases efficiency of combustion.

Although above-mentioned be described the specific implementation mode of utility model in conjunction with attached drawing, not to the utility model The limitation of protection domain, based on the technical solution of the present invention, those skilled in the art need not pay creativeness The various modifications or changes that working can make are still within the scope of the present invention.
