Description

Counter-burning type rural area combustion wood stove kitchen range

This practicality relates to a kind of counter-burning type rural area combustion wood stove kitchen range.

China is a large agricultural country, fire coal uses in vast rural area, the quantity of coal-fired peasant household also progressively increases thereupon, but from map of China, China's major part is the mountain area, and be again to lack the coal district mostly, so fuel wood is the main energy sources in these area lives, on the other hand, from the cooking stove and the combustion method of combustion bavin, be still and rest on several thousand the original level, blazing up, Dark smoke billows, because the surprising waste of combustion wood stove kitchen range and combustion method has caused the in great shortage of combustion bavin resource for a long time.The firewood-saving stove that promote the beginning of the eighties, the thermal efficiency increases, but burner hearth and kitchen range door are little, manipulate inconvenience.

This is suitable for, and novel purpose is to provide a kind of thermal efficiency height, heat loss is little, tail gas is little, easy for operation to the pollution of environment, broken, powder, the shell class that is fit to various fuel woods and the crop counter-burning type rural area combustion wood stove kitchen range of shape fuel combustion that looses.

In order to achieve the above object, this method that is suitable for novel solution is as follows: whole combustion wood stove kitchen range divides three sections of upper, middle and lower, comprises that furnace shell, combustion chamber, inner cone penetrate the oxygen bottle and advance the bavin pipe; Place the cone on the combustion chamber to extend to the cooking stove epimere, the anti-pot shape grate both sides of the charcoal burning chamber of holding concurrently again simultaneously are manual and motor-driven charcoal feeding pipe, and offgas duct is communicated with the tail gas road; Hypomere is grey charcoal diversion mechanism, comprises deashing bar, upset activity grate, ashes bucket, and both sides are provided with manual carbon outlet bucket and motor-driven asepwirator pump.

After having adopted such structure, because cooking stove has been divided into two combustion chambers up and down, the high fireworks that fuel gas produced that have been heated and emitted when having utilized fuel wood just to fire, the no fireworks characteristics that last charcoal produces during with after-burning, and temperature keeps the advantage of enriching heat in the charcoal, Each answers the purpose intended with its two kinds of fire, significantly reduced the loss of heat; At combustion wood stove thorax center inner cone is set and penetrates the oxygen bottle, for resistant to elevated temperatures ceramic material forms, not only there is not the end, and from top to bottom, ascending several eyelets that on bottle, bored, the eyelet maximum on bottle top wherein, it and ventilation combustion chamber add grate, can be simultaneously in the stove to core, periphery, the upper and lower oxygenation of flame, required oxygen-supplying amount when guaranteeing fuel gas detonation in the fuel wood reaches abundant burning; Owing to adopted oval inclined tube charging, irregular fuel wood can enter upright burning in the stove, add deashing bar, the poker that is provided with in two combustion chambers and the carbon outlet bucket and push away the charcoal bar, can make well-ventilated in the stove; Be located at the charcoal burning chamber of cooking stove epimere, the formed high temperature of the anti-burning of charcoal does not have fireworks to carry out the heat exchange except that direct and kitchen range face bowl, also can be to the not fully burning on a small quantity of emitting up from following fuel wood combustion chamber, the free shape carbon granule black smoke that is produced carries out sufficient high-temperature chemical reaction once more, make it reach smokeless emission, reduced pollution environment; The heated-separated wall that is provided with, the main fire that rises in the middle of can making with return the ember tail gas that is mapped to the edge and take their own roads, the vortex that does not allow tail gas form stops the bottom of a pan and influences last heat exchanger effectiveness; The grey charcoal diversion mechanism of cooking stove hypomere is to realize the anti-prerequisite of burning in second combustion chamber, and the manual carbon outlet bucket of setting and motor-driven asepwirator pump can satisfy the different levels user and reach the needs that directly use and reclaim charcoal; Mix funnel at oval charging inclined tube, poker, plate and turning joint ball can make the automatic feed of all even realization bulk cargo of burning, manipulate very convenient.

Further describe utility model below in conjunction with accompanying drawing

Fig. 1 is the vertical view of an embodiment of the present utility model.

Fig. 2 is the cutaway view of Fig. 1 along I-I.

Fig. 3 is the cutaway view of Fig. 1 along II-II.

Fire the wood stove kitchen range as Fig. 1, Fig. 2, counter-burning type rural area shown in Figure 3, whole cooking stove divides three sections of upper, middle and lower, and the stage casing is for burning first combustion chamber 11, the combustion chamber 13 that bavin is used, and inner cone is penetrated oxygen bottle 12, advanced bavin pipe 6, is preheated air interlayer 8 between combustion chamber 13 and furnace shell 5; Place the cone above the combustion chamber 13 to extend to the cooking stove epimere, the anti-boiler bridge 9 of second combustion chamber 8 of double again burning charcoal of while and the cooking-pot type grate 10 that interlocks, both sides are manual charcoal feeding pipe 4 and motor-driven charcoal feeding pipe 2, opposite side is an offgas duct 1, tail gas road 7 is communicated with offgas duct 1, bell 3 times and be heated-separated wall 20; Hypomere is grey charcoal diversion mechanism, comprise upset activity grate 14, its regulation and control turn-knob stretches out furnace shell 5 outsides, penetrating between the oxygen bottle 12 at grate 14 and inner cone is deashing bar 17, the handle of bar also is to stretch out beyond the furnace shell 5, push away the manual carbon outlet bucket 15 of screen mesh type and the ashes bucket 16 of charcoal bar below the grate 14 for band, the terminal quarrel of carbon outlet bucket 15 communicates with motor-driven asepwirator pump 19, and charcoal just can enter second combustion chamber 8 of burning charcoal respectively by manual carbon outlet bucket 15, manual charcoal feeding pipe 4 and motor-driven asepwirator pump 19, motor-driven charcoal feeding pipe 2; Charcoal feeding pipe 2,4 and advance bavin pipe 6 and be ellipse, charcoal feeding pipe 4 and to advance bavin pipe 6 be again can mix funnel, poker, plate to regulate control burning the loose inlet amount and the air inflow of shape fuel wherein, and regulate the charging angle by the turning joint ball 21 that is provided with; Three sections parts at furnace shell 5 are provided with air admission hole, and the area that air inlet amounts to is less than the sectional area of tail gas mouth and offgas duct 1.
