Abstract

The utility model provides a new coal-fired furnace, which belongs to a coal burning device. The utility model comprises a furnace body, a coal inlet at the upper part of the furnace body, a deslagging chamber outer shell at the lower part of the furnace body, an umbelliform furnace core with vent holes in the furnace body fixed at the upper part of the air intake bushing, a slag removing fork below the furnace core fixed outside the air intake bushing, an upper grate with a slag tapping hole arranged below the slag removing fork, a lower grate with the other slag tapping hole arranged below the upper grate and a grate pallet below the lower grate. The air outlet end whose upper part is arranged in the air intake pipe of the air intake bushing is arranged under the furnace core, while a handle and the other handle are respectively arranged on the lower grate and air intake bushing. This coal-fired furnace is reasonable in structure and convenient for using, which not only can take massive coal as fuel but also can take powdery coal or fault coal as fuel so as to reduce the using cost, to realize a complete combustion, a high thermal efficiency, easy fire banking and rapid fire raising. This furnace can be made into a vertical-type drinking furnace, a small warming furnace, a restaurant-used coal-fired stove and other vertical-type small coal-fired furnaces.

Description

A kind of novel coal body of heater

Technical field

The utility model provides a kind of coal-burning installation, particularly a kind of body of heater.

Background technology

Present widely used coal-fired drinking-water stove, small-sized coal heating stove, the restaurant small-sized coal furnace of coal-fired stove and other purposes, because the reason of fire grate structure, all be that lump coal with high-quality is fuel, and can not be fuel, cause use cost higher with the coal (smalls) or the colm of powdery.And in the use of these coal stoves, coal combustion is insufficient, and the thermal efficiency is lower, and coal consumption amount is higher.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of novel coal body of heater is provided, and it can be a fuel with powdery coal or colm, to reduce use cost, improves the thermal efficiency.

The utility model is to realize like this, a kind of novel coal body of heater, it has internal furnace, coal feed point and outlet flue are arranged at internal furnace top, the slagging-off chamber enclosure is arranged at the bottom, there is the combustion chamber of the umbrella shape of taking pore out of to be fixed on the upper end of air intake sleeve pipe in the internal furnace, fork pokes fire above the combustion chamber, the below of combustion chamber has the scarfing cinder fork to be fixed on the outside of air intake sleeve pipe, there is the upper fire-grating of taking cinder hole out of scarfing cinder fork below, there is the lower fire grating with another scum hole the upper fire-grating below, there is stocker tray the lower fire grating below, upper fire-grating, stocker tray is by being bolted in the slagging-off chamber enclosure, the outlet side that top is positioned at the blast pipe of air intake sleeve pipe is positioned at below the combustion chamber lower fire grating, handle and another handle are arranged respectively on the air intake sleeve pipe.

Adopt the novel coal body of heater of said structure, rational in infrastructure, easy to use, can lump coal be fuel both, also can the powdery coal or colm be fuel, reduced use cost, sufficient combustion, thermal efficiency height is banked up a fire easily, to carry fire fast.Can utilize this body of heater to make vertical drinking-water stove, small heater stove, restaurant coal-fired stove and other vertical small-sized coal furnace.

Description of drawings

Fig. 1 is that the master of a kind of example structure of the present utility model looks schematic diagram.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the vertical view behind internal furnace etc. of removing of a kind of example structure of the present utility model.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model and using method.

As shown in drawings, a kind of novel coal body of heater of the utility model, it has internal furnace (1), coal feed point (2) and outlet flue (21) are arranged at internal furnace top, slagging-off chamber enclosure (13) is arranged at the bottom, there is the combustion chamber (4) of the umbrella shape of taking pore (6) out of to be fixed on the upper end of air intake sleeve pipe (15) in the internal furnace, fork (5) pokes fire above the combustion chamber, the below of combustion chamber has scarfing cinder fork (7) to be fixed on the outside of air intake sleeve pipe, there is the upper fire-grating (9) of taking cinder hole (8) out of scarfing cinder fork below, there is the lower fire grating (10) with another scum hole (14) the upper fire-grating below, there is stocker tray (12) the lower fire grating below, upper fire-grating, stocker tray is fixed in the slagging-off chamber enclosure by bolt (19), the outlet side that top is positioned at the blast pipe (16) of air intake sleeve pipe is positioned at below the combustion chamber lower fire grating, handle (18) and another handle (17) are arranged respectively on the air intake sleeve pipe.

The bottom of blast pipe is stretched out in the outside of slagging-off chamber enclosure and can be connected with air blast.The upper end of blast pipe has fixing deep bead (20) to be placed in the groove of air intake sleeve pipe upper end.The fork length that pokes fire on the combustion chamber is interspersed.Can have except that cinder notch on the slagging-off chamber enclosure, removing the cinder notch outside can have door.Ball (11) can be arranged, so that the rocking of lower fire grating between lower fire grating and the stocker tray.

During use, rotate lower fire grating, make the scum hole location dislocation on the upper and lower fire grate be in the state that is closed, leak down to prevent fire coal to scum hole by handle (18).Fire coal is placed on above the combustion chamber and with firewood etc. ignites.Utilize air blast in combustion chamber, to blow by blast pipe.The wind that enters in the combustion chamber enters in the fire coal from the venthole on the combustion chamber, plays combustion-supporting effect.When needing to loosen fire coal, can rock the air intake sleeve pipe by another handle (17), thereby rock combustion chamber, make fire coal become loose, sufficient combustion.When the air intake sleeve pipe rocks, drive the scarfing cinder fork simultaneously and rock, the slag that falls is fallen the bottom except that the grit chamber from the cinder cleaning hole on the upper and lower fire grate.Fire coal is sent into from coal feed point, and the flue gas that produces behind the coal combustion is discharged from outlet flue.

A plurality of scum holes are arranged respectively on the upper and lower fire grate, the area of the non-scum hole part between each scum hole on the fire grate is greater than the area of scum hole, be that scum hole on the upper and lower fire grate is when misplacing to a certain degree, non-scum hole part on certain fire grate can be blocked the scum hole on another fire grate, banks up a fire with realization.Adjust the degree of misalignment of two fire grates, can adjust the intake of scum hole.By rotating lower fire grating, can ventilate or remove the gred when making the scum hole alignment on the upper and lower fire grate.

After the outside of internal furnace installs tank shell additional, can as native heating installation carry out heating or as drinking-water stove.After the cooking mouth is left in the internal furnace upper end, can be used as coal-fired stove, carry out operations such as cooking.

Also has radiating tube (3) on the top of described internal furnace (1).Because the existence of radiating tube, the heating surface area of coal-fired body of heater increases, and has improved heating efficient.Moreover the part pyrotechnics in the internal furnace rises along radiating tube, and resistance is little, carries at top speed and spending soon.
