Abstract
The utility model discloses an underground combustion furnace convenient for charging, comprising a furnace cavity, wherein the furnace cavity is arranged below the ground; a heat outlet of the furnace cavity is arranged above the ground; a material inlet of the furnace cavity is close to the ground; the lower part of the furnace cavity is communicated with an ash cavity by a furnace grill; and an air duct communicated with the upper part of the ground is arranged in the ash cavity. The underground combustion furnace convenient for charging, disclosed by the utility model, has the beneficial effects that: compared with the prior art, the furnace cavity is arranged below the ground, and the material inlet is close to the ground, so that the furnace does not need to be lifted up in a fuel charging process, and the fuel only needs to be pushed in the material inlet, namely, the fuel can directly enter in the furnace cavity by an effect of gravity; in addition, the air duct communicated with the ground is arranged in the ash cavity, so that the problem on normal combustion of the furnace cavity below the ground is solved, and the normal use of the furnace cavity below the ground is guaranteed; and therefore, low-density combustible materials such as crops straws and the like can be conveniently used as fuels, the utilization rate of the furnace can be greatly increased, the usage amount of coals can be reduced, the environmental protection level is greatly increased, the energy resources are saved, and the cost of processing the straws by the people is decreased.
Description
Technical field
The utility model relates to firing equipment, relates in particular to a kind of underground combustion furnace of being convenient to feed in raw material.
Background technology
At present, the rural area, many crop materials are not rationally utilized, serious waste of resources.The stalk use that acts as a fuel is extremely taken a lot of work when in common stove, adding, so people are unwilling to use, but a large amount of the use added coal easily.Substitute coal if can make fuel with discarded stalk, can improve the environmental protection level, energy savings reduces the cost that the peasant handles stalk.
The utility model content
To the problem that exists in the prior art, the purpose of the utility model be provide a kind of simple in structure, add that fuel is convenient, the underground combustion furnace of being convenient to feed in raw material of low preparation cost.
For realizing above-mentioned purpose, the technical scheme of the utility model is following:
A kind of underground combustion furnace of being convenient to feed in raw material comprises burner hearth, and said burner hearth is arranged on underground; Said burner hearth heating outlet is positioned at more than the ground; Said burner hearth charging aperture and ground are approaching, and said lower furnace portion is communicated with grey thorax through fire grate, are provided with in the said grey thorax and coconnected air channel, ground.
Further, said upper furnace also is provided with and coconnected auxiliary air channel, ground.
Further; Said auxiliary air channel comprises Vertical Channel and circular passage; Said Vertical Channel one end opening is arranged on more than the ground; Other end opening is communicated with the bottom, circular passage, and said circular passage is arranged on said upper furnace, is provided with a plurality of regularly arranged air vents on the inner ring surface top near said burner hearth.
Further, said roof of the furnace is provided with the heating outlet approaching with ground.
Further, on the said heating outlet boiler can be installed.
Further, on the said heating outlet hot-blast stove can be installed.
Further, the feeding-passage for tilting between said charging aperture and the burner hearth.
Further, it is characterized in that, but said charging aperture is connected with the cover plate of folding.
Further, said burner hearth is a tubular, and said feeding-passage is communicated with said burner hearth side, and the connection position is positioned at said fire grate top.
Further, said fire grate is a rectangle, and quantity is two, and said every fire grate all can be around long outside, and upwards upset erects in said burner hearth.
The beneficial effect of the utility model is, the utility model compared with prior art, the utility model places burner hearth underground, charging aperture is near ground; When adding fuel, need not to lift, only need to push fuel and can directly get into burner hearth, the air channel that is communicated with ground is set in grey thorax in addition through the gravity effect from charging aperture; Solved the problem of burner hearth in the underground fuel normal combustion, guaranteed burner hearth in underground normal use, this just makes the utility model can use low-density combustibles such as crop material to act as a fuel easily; Can improve the utilization rate of stove and accessory greatly, reduce the use of coal, improve Environmental Protection Level greatly; And practiced thrift the energy, and having reduced the cost that people handle stalk, last the utility model is simple in structure; Low preparation cost helps large-scale popularization, and good market prospects and economic worth are arranged.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain:
Fig. 1 is the plan structure sketch map of a kind of underground combustion furnace of being convenient to feed in raw material of the utility model;
Fig. 2 be among Fig. 1 A to the sectional structure sketch map;
Fig. 3 be among Fig. 1 B to the sectional structure sketch map.
The specific embodiment
The exemplary embodiments that embodies the utility model characteristic and advantage will be described in detail in following explanation.Be understood that the utility model can have various variations on various embodiment, the scope of its neither disengaging the utility model, and explanation wherein and accompanying drawing be the usefulness of being used as explanation in itself, but not in order to restriction the utility model.
Like Fig. 1-shown in Figure 3, the utility model comprises body of heater 1, and body of heater 1 is a closed cylinder.Body of heater 1 internal upper part is a burner hearth 2, and the bottom is grey thorax 3, is separated by fire grate 4 between burner hearth 2 and the grey thorax 3, and burner hearth 2 internal combustion are residual to be leaked in the grey thorax 3 through fire grate 4.Burner hearth 2 tops are heating outlet 5, and this heating outlet 5 is approaching with ground, the convenient equipment that is used to heat of installing.The flue gas of burner hearth 2 and the heat overwhelming majority are discharged through heating outlet 5.The heat sink of boiler or hot-blast stove can be installed on this heating outlet 5, can adopt two kinds of fuel handling modes of the utility model and boiler self heating, more flexible.
For the fuel that conveniently is embedded in the underground burner hearth 2 can carry out normal combustion, an opening pipeline is set on the position near fire grate 4 in grey thorax 3, this pipeline other end open communication forms air channel 8 to more than the ground.In grey thorax 3 can be introduced from ground with wind in this air channel 8, and blow to burnt fuel, make burner hearth 2 fuel normal combustion through fire grate 4.This air channel 8 can be adopted a plurality of.This air channel 8 has guaranteed the gas that fuel combustion is required, makes body of heater 1 also can normally use underground.
The beneficial effect of the utility model is; The utility model compared with prior art, the utility model places burner hearth 2 underground, charging aperture 6 is near ground; When adding fuel, need not to lift, only need to push fuel and can directly get into burner hearth 2 through the gravity effect from charging aperture 6.The air channel 8 that is communicated with ground is set in grey thorax 3 in addition, has solved the problem of burner hearth 2, guaranteed that burner hearth 2 is in underground normal use in the underground fuel normal combustion.This just makes the utility model can use low-density combustible such as crop material to act as a fuel easily, can improve the utilization rate of stove and accessory greatly, reduces the use of coal, improve Environmental Protection Level greatly, and practiced thrift the energy, has reduced the cost that people handle stalk.Last the utility model is simple in structure, and low preparation cost helps large-scale popularization, and good market prospects and economic worth are arranged.
