Description

Top-blown back-burning coal kitchen range

The utility model belongs to a kind of coal-fired cooking kitchen range.

What traditional coal-fired cooking kitchen range adopted is upper coal feeding, following air feed, and when burning, the airborne oxygen that supplies at first supplies underlying seam, and the coal seam of top burning is an anoxic layer.A large amount of flammable fugitive constituent that coal produces in combustion process and flammable molecule are because containing hypoxgia and can't form burning in the surplus air, and under the situation of anoxic, flammable fugitive constituent and flammable molecular conversion are carbon black, form black smoke from the chimney back of emerging.The air feed of the coal-fired cooking kitchen range of tradition is that the grit that blows afloat during air feed, lime-ash directly enter flue and enter atmosphere, have increased dust-exhausting quantity, have not only caused pollution to atmosphere by the direct supply cold wind of air blast, has also caused the waste of the energy simultaneously.

The purpose of this utility model provides the counter-burning coal-fired cooking kitchen range of a kind of top blast, changes the structure of coal, air supply mode and traditional kitchen range, makes coal when burning, and abundant and oxygen mix reaches completing combustion, thereby reduces atmosphere pollution, improves the heat energy utilization rate.

The purpose of this utility model is achieved in that

The counter-burning coal-fired cooking kitchen range of this top blast, comprise the combustion chamber, the kitchen range core, the kitchen range wall, kitchen range mouth and chimney, it is characterized in that: the top of kitchen range core is the infundibulate combustion chamber, the bottom is cylindrical coal store, the outside, kitchen range core bottom is an annular ash accumulating chamber, between kitchen range core and the kitchen range wall is smoke chamber, connect the combustion chamber in the kitchen range door opening, connect the kitchen range wall outward, kitchen range door and smoke chamber are separated, meet ash accumulating chamber in the ash door opening, connect the kitchen range wall outward, the ash door is separated with smoke chamber, smoke chamber is connected with road in two telescopic hot air flues, the hot air flue outer course is connected with a top blast airduct that runs through kitchen range core central authorities, also increases airduct with a secondary annular that places the kitchen range mouth and is connected, and raises coal feeder on foot-operated to be contained in kitchen range core central lower, mainly by placing the outer jacking tooth bar of top blast airduct No. one time, the coal-supporting disk that is connected with the jacking tooth bar, lock very heavy, it is very heavy to hoist, with the very heavy very heavy connecting rod that hoists that is connected that hoists, hinge, spring, pedal is with locking very heavy and the very heavy pull bar that is connected that hoists, very heavy spring, the pull bar handle is formed.

No. one time top blast airduct upper end is provided with conical blast cap.The air port that the secondary annular increases airduct is vertical 60 ° of annular array that make progress.Top, combustion chamber is provided with the flower basket type burner.

When this kitchen range operation, after the cold wind that air blast is sent enters the outer course of double braid covering cartridge type hot air flue, enter top blast airduct and secondary annular again and increase airduct, cold wind is by the useless smoke pre-heating in road in the hot air flue, wherein, after No. one time the top blast airduct passes through the preheating of kitchen range in-core portion again, temperature is reached the top that 300 ℃ hot blast is delivered to the flower basket type burner, blast cap returns hot blast uniformly and blows on burning coal layer, hot blast makes flame pass flower basket type burner hole on every side, return along the infundibulate combustion chamber, concentrate on the bottom of a pan.The cold wind that increases airduct by the secondary annular is blown out by the air port of even laying after preheating, forms about 250 ℃ annular air curtain, oxygen is fully mixed with flammable fugitive constituent and flammable molecule, burning is complete, and pilot flame is concentrated to the bottom of a pan, and direct exhaust enters smoke chamber.The soot particle that produces in the combustion process, waste residue are blown into the bell mouth of bottom, combustion chamber through top blast airduct, fall into the semiclosed ash accumulating chamber of annular, avoid effluxing.Simultaneously, the lime-ash on burning coal layer surface is constantly removed by wind, thereby has guaranteed the abundant burning in coal seam.

After the waste gas that produces during burning rose, the annulus from the combustion chamber far from the bottom of a pan was returned downwards into smoke chamber, and smoke chamber is made of the space of kitchen range wall and cylindrical shape kitchen range core, linked up with hot air flue, made waste gas further purify the back at smoke chamber and discharged.

Raise coal feeder under foot-operated and be contained in kitchen range core central lower, mainly by placing the outer jacking tooth bar of top blast airduct No. one time, the coal-supporting disk that is connected with the jacking tooth bar, the locking very heavy, hoist very heavy, with very heavy hoist very heavy connecting rod, spring, the pedal that is connected that hoist, form with the very heavy pull bar that is connected of jacking, very heavy spring, pull bar handle with locking is very heavy.Once coal is added coal store before the use, when superjacent burnt, preheating, dehydration, drying were carried out in contiguous coal seam, bottom, and separate out flammable fugitive constituent gradually, fully mix after-combustion with oxygen, the residual cinder in burning back is ejected, and falls into ash accumulating chamber along bell mouth under the combustion chamber.When stepping pedal, spring is compressed, and the very heavy connecting rod that hoists is that the center of circle moves downward with the hinge, lifts to hoist very heavyly, holds up the jacking tooth bar and moves upward.At this moment, be connected coal-supporting disk on the jacking tooth bar and move upward and hold up coal, finish a jacking process.Locking very heavy being vertically mounted on the kitchen range base plate hole wall plays the role of positioning.

When jacking behind extreme position, pulling pull bar handle makes that locking is very heavy, hoisting very heavyly pulls back simultaneously, compress very heavy spring, hoist and move after very heavy, break away from the jacking tooth bar, under the deadweight effect, coal-supporting disk slides into the bottom downwards along an airduct, finishes the upper coal feeding action.

The utility model has the advantages that:

Top blast wind, the jacking coal can make fully coal-fired and oxygen mix, reaches completing combustion, and programming rate is fast, and heat loss is few; The flue dust blackness is 0～1 grade of Lin Geman (during igniting 1 grade, after the normal combustion 0 grade), smoke density is low, has reduced the environmental pollution of cooking kitchen range waste gas, waste residue; Combustion chamber, smoke chamber, ash accumulating chamber effectively separate flame, waste gas, lime-ash, and be simple in structure, easy accessibility; Two telescopic hot air flues utilize heating by the exhaust gases cold wind, and the cold wind after the preheating reaches 250～300 ℃, economize on coal 20～40%, have improved the thermal efficiency; It is easy to operate to raise coal feeder on foot-operated, and coal can continuous coal-fired 3-4 hour; Adopt prefabricated components, can manufacture, solved the problem that a kitchen range one is built.Applicable to various bituminous coal coals and various forms of single, multi-hole kitchen range.

Below in conjunction with drawings and Examples the utility model is further described:
