Description

Use the cooking range of biomass granule fuel

Technical field

The utility model relates to cooking stove, and especially a kind of cooking range that uses biomass granule fuel is particularly suitable for samll cities and towns, rural area, refreshment bar and family and adopts.。

Background technology

At present, many local hotel, restaurant and unit dining rooms of China cooking range used is made fuel with fire coal, diesel oil or liquefied petroleum gas, although easy to use, calorific value is high, but fire coal can cause environmental pollution, harm people are healthy, many local coal-fired uses that limited; And burning diesel oil or liquefied petroleum gas, cost is high, waste in a large number again resource.In recent years, a kind of is the plant fuel that a kind of wide material sources, low price do not pollute the environment again with firewood, tangerine bar, branch, leaf, hay and wood-curing waste through the biomass compact forming particle of pulverizing and be pressed into.But, make us feeling regrettably prior art also untapped go out corresponding various cooking stoves for people to use.Chinese utility model patent discloses " burner of the compact formed particle gasification, and combustion of a kind of biomass environment " (patent No. is ZL201210346054.4), but this burner is the special exploitation of boiler and coaster for baking tobacco, and is not suitable for cooking use.Also has in the prior art a kind of cooking brick kitchen range of making fuel with biological substance shaped granule, because this cooking brick kitchen range volume is larger, adopt again screw feeder to feed in raw material, automaticity is higher, and only suitable hotel, hotel and large unit or school lunch service are used.As everyone knows, the stove that snack bar, eating house and family are used is all that volume is little, the cooking range of simple structure, what especially rural area and samll cities and towns were used is nearly all little cooking range, if this regenerated resources of living beings can be applied on the very wide little cooking range of use face, this is to reducing environmental pollution, save coal and petrochemical industry resource, reduce fuel cost and there is far reaching significance.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of simple in structure, the cooking range of easy to operate use biomass granule fuel.

Above-mentioned task realizes by this way: a kind of cooking range that uses biomass granule fuel, include body of heater, burner, flue, bellows, dust collecting box, unload hawk, electric heat ignition rod, and blast pipe converter, it is characterized in that a manual feeder of step-by-step movement in addition, the manual feeder of described step-by-step movement is by charging spout, scraping wings, charging ram, end cap and intermittently lever body composition, the front end of horizontal charging spout is communicated with flue, above charging spout rear end, be provided with charge door, the scraping wings identical with charging spout endoporus is placed in charging spout, the charging ram linking with it stretches to charging spout through end cap, intermittently lever body is arranged at end cap outside, engage and form by push rod box and locking bar box, in the push rod box of being close to end cap, be provided with a lath-shaped pusher plate, this pusher plate is placed on charging ram with push-rod hole and charging ram loose fit in the middle of it, on the charging ram between pusher plate and end cap, be provided with a Compress Spring, in the push rod box of pusher plate lower end, be provided with a rocker-arm pusher grip, the upper end of this pusher grip contacts with outboard end under pusher plate, stirring outside the opening that handle extends to push rod box lower end of its underpart, in locking bar box, be provided with a lath-shaped check plate, this check plate is placed on charging ram with its non-return hole and the charging ram loose fit of middle and upper part, on the charging ram between check plate and push rod box, be provided with a Compress Spring, be articulated with in the upper end of check plate on the banking pin of inwall of locking bar box, its lower end extends to outside the opening below locking bar box.

In technique scheme, charging spout cross section is positive square or round, and its height or diameter and the ratio of flue height are 0.50～0.75: 1 its length is 1.5～2: 1 comparatively suitable with the ratio of flue height.

In technique scheme, the thickness of lath-shaped pusher plate and check plate is with 3～4 millimeters, and gap between charging ram is taking 0.5～1.0 millimeter as suitable.

The utility model is work like this: the check plate of first pulling locking bar box before use, allow it not block charging ram, the charging ram of charging spout is pulled to rear end, then reinforced until fill it up with toward charging spout by charge door, the pusher grip of then stirring outward push rod box, because push-rod hole and the charging ram of the pusher plate of push rod box are loose fit, the pusher plate hypomere contacting with pusher grip is tilted to flue, its push-rod hole inner side is pressed (biting) pull bar and is made it interior mobile toward flue, the scraping wings linking with it just moves, furnace charge is shifted onto in stove, while loosing one's grip after pusher grip is allocated to the end, the elastic force effect lower push-rod plate of Compress Spring is just returned to reset condition, the pusher grip of contact is also replied home position with it, slurcam plate just no longer blocks charging ram.Now, under the indoor Compress Spring elastic force effect of locking bar, check plate lower end swings run-off the straight outward, and its non-return hole also tilts, and pull bar is just pressed in inner side, non-return hole, fastens pull bar pull bar can back not moved, and stops on this position.In the time that furnaceman stirs the pusher handle of push rod chamber again, as above-mentioned principle, scraping wings is reinforced in toward a mobile segment distance in flue toward flue, just can constantly the furnace charge in charging spout be delivered in flue as only stirred again and again pusher handle.When furnace charge in flue covers electrothermal ignitor, furnace charge is lighted in energising, furnace charge is lighted rear power-off, and forward blast pipe converter to dust collecting box blast pipe, start air blast, wind unloads hawk through rotating air vent from dust collecting box enters in flue combustion-supporting, after furnace charge combustion in flue is prosperous, forward the air outlet of blast pipe converter to bellows blast pipe, wind enters and in flue, accelerates the furnace charge gasification, and combustion in flue from the air intake aperture of flue, the interior furnace charge burning of flue subsequently enters normal combustion process, just can by intermittently constantly feeding in raw material and unloading ash.

In sum, useful technique effect of the present utility model is as follows: the utility model is except having incendivity bio-regeneration fuel, reduce environmental pollution, save coal and petrochemical industry resource and reduce outside fuel cost, also have simple and compact for structure, maneuverable advantage, the cooking range that is particularly suitable for samll cities and towns and rural area adopts, and has opened market widely out-of-the-way for applying biological substance shaped granule fuel.
