Description

Non-radiating type rich oxgyen energy-saving cooking furnace

It is the domestic stove of fuel with the moulded coal that the utility model relates to a kind of, refers to a kind of energy-conservation and energy-conservation cooking stove of non-heat radiating type oxygen enrichment environmental protection efficacy of having especially.

Commercial coal stove generally is traditional structure at present, its thermal efficiency only is 10-20%, the highlyest do not exceed 24%, thereby expend a large amount of energy, because burning is insufficient, cause a large amount of pernicious gas atmosphere pollutions, particularly be to produce carcinogenic gas, human body is had very big harm, the upward type energy-saving quick-ignited honeycombeded moulded coal of igniting and the stove and accessory thereof of existing a kind of introduction, has effect significantly energy-conservation and the elimination flue dust, but it exists use inconvenient, can't bank up a fire the complex structure heaviness, and coal price is too expensive, particularly is can't bank up a fire to cause rekindle daytime to cause waste and inconvenience.When having plenty of the very hot oven of need again, existing stove and accessory mostly need be used the air blast air blast, causes very big smoke contamination.

Goal of the invention of the present utility model is to disclose a kind of good energy-saving effect that has, and reduces the stove and accessory of pernicious gas and smoke contamination, and it has the function that very hot oven is provided rapidly.

The technical scheme that realizes goal of the invention of the present utility model is: comprise the oxygen enrichment generation device, the stove bucket, the stove bucket is built-in with tile, be provided with heat-barrier material between tile and the stove bucket, stove bucket bottom is provided with an air door plate, foot under the stove bucket is an angle-iron frame, key is that tile is the oxygen enrichment air return tile, be provided with a coal lifting frame in the air return tile, the top of air return tile is provided with a fire drawn cover, a ring-type oxygen enrichment siphunculus is established in stove bucket bottom, and the oxygen riched hole that its internal ring wall is provided with in a plurality of ventholes and the oxygen enrichment air return tile wall joins, and the air admission hole of the outer wall of oxygen enrichment siphunculus is connected with the oxygen enrichment generation device.

When the utility model uses, because the structure uniqueness of oxygen enrichment air return tile, so the moulded coal to burning is made secondary air, make burning more thorough, efficiency of combustion improves, and make pernicious gas by after-flame or decomposition, simultaneously, as the need very hot oven, then can start the oxygen enrichment generation device, oxygen enrichment is transported to the moulded coal top of burning rapidly, and under the effect of oxygen rich gas, the coal-fired intensity of a fire rises rapidly, when no longer using very hot oven, then can turn off the oxygen enrichment generation device, so it is the flue dust that the utility model produces is very few, simultaneously extremely easy to use.

Provide the structure of the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the structure chart of oxygen enrichment siphunculus of the present utility model.

Fig. 3 is the front view of coal lifting frame of the present utility model.

Fig. 4 is the vertical view of coal lifting frame of the present utility model.

See also Fig. 1-Fig. 4, the structure of embodiment of the present utility model is: comprise oxygen enrichment generation device 19, stove bucket 13, stove bucket 13 is built-in with tile, be provided with heat-barrier material 11 between tile and the stove bucket 13, stove bucket 13 bottoms are provided with an air door plate 15, the foot of stove bucket 13 is an angle-iron frame 17, play a supportive role, key is that tile is an oxygen enrichment air return tile 10, and it provides secondary return air and the oxygen enrichment passage is provided, be provided with coal lifting frame 20 in the air return tile 10, the top of air return tile 10 is provided with a fire drawn cover 3, and a ring-type oxygen enrichment siphunculus 18 is established in the bottom of stove bucket 13, and the induction port on its internal ring wall is connected with oxygen enrichment generation device 19.

The structure of aforesaid oxygen enrichment air return tile 10 is: it is the garden tubbiness, longitudinally be provided with the coal frame pipeline of 4 half openings on the internal chamber wall, watt top is the slope, the slope is provided with 4 coal frame grooves, it is stupefied that oxygen enrichment air return tile 10 inwalls are provided with longitudinally protruding wind-guiding, its quantity is the 4-12 root, also has 4-12 root return air duct 7 in air return tile 10 walls, the upper end of return air duct 7 is positioned at the below, slope, its effect is that fire coal is made the secondary oxygen supply, and the lower end of return air duct 7 is positioned near the air door, is called air admission hole 14, in an air part of being advanced by air door directly enters moulded coal in the air return tile 10, and along rising between watt inwall and the coal and on the hole in the moulded coal, for once advancing oxygen, portion of air enters return air duct 7 by air admission hole 14 simultaneously, air is subjected to expanding after the heat effect of watt wall and rises, and makes the secondary oxygen supply to the furnace chamber of coal end face to the upper end.

The structure of aforesaid coal lifting frame 20 is that coal frame bottom is for cross, each cross termination protrudes upward a root post, column upper end sideling outwardly the top extend to form horn-like, there is an apical ring the top, the top of apical ring and 4 diagonal shell of columns is connected in one, during use coal lifting frame 20 is placed in the air return tile 10, coal frame pipeline tabling on the column of coal lifting frame and the air return tile wall, the diagonal shell of column of while column upper end and the coal frame groove tabling of air return tile 10, then moulded coal is put in coal lifting frame, works as the afterburnt, and coal lifting frame is taken out by the stove top, after having gone out quarrel, again coal lifting frame 20 is put into furnace chamber.
