Description

Self-suction type alcohol synthetic fuel vapourizing stove

The utility model is a kind of evaporation furnace that uses the self-priming supercharging of alcohols synthetic fuel, is a kind of desirable cooking stove, make simple eye or the eyes cooking stove use all can, and the height of level of fuel is below or above burner and all has no relations in the fuel tank.Be particularly suitable for hotel, dining room, restaurant, family's mutton cooked in a chafing pot usefulness.

At present, the stove and accessory of the mutton cooked in a chafing pot that generally uses on the dining table, to must have cylinder for liquefied gas with what oil liquefied gas was done fuel, and to oil liquefied gas be transported on the stove and accessory of dining table with sebific duct, and be the Hotpot stove of fuel with diesel oil and gasoline, to constantly inflate pressurization in the use in the fuel tank, and after just having beaten gas and having used a period of time, pressure in the fuel tank is different can not evenly the burning, and this stove of inflating pressurization should not use to old and child, weak and sickly people.The oil flavor contaminated air that distributes simultaneously, greasy dirt makes the bottom of a pan produce carbon distribution and grease again, in addition in the vaporescence of fuel, not to be passed to burner after oil plant is gasified totally, always carry the fuel that some are not vaporized as yet secretly, cause the asynchronous of burning and vaporization, " phenomenon of breathing " promptly taken place made the burning of fuel abundant inadequately, the thermal efficiency is not high.

The stove and accessory of useful charcoal was both unhygienic again, and anthracemia easily takes place again, and in a word, used stove and accessory exists and uses main disadvantage inconvenient and that pollute easily.

The purpose of this utility model is that providing a kind of is fuel with the alcohol synthetic liquid fuel, need not inflate in the self-priming use and keeps stove and accessory uniform pressure burning, that the thermal efficiency is high.

For this purpose, structurally stove and accessory is made combustion chamber and body of heater two large divisions; Body of heater itself divides top and the bottom again; The liquid fuel tank in bottom is the oblate cylinder that steel plate is welded into, and top and bottom are sphere; Adopting this structure is in order to make stressing conditions more good, and capacity is also bigger.Adopt steel plate to be washed into two housings up and down, middle welding forming.Having the filler of a fuel on the limit of fuel tank top sphere, and wear the lid that screw thread can be tightened, is sunk in the middle of the sphere, open a circular hole, insert the steel pipe of a band chimb, chimb and circular hole periphery weld together, and steel pipe length reaches the bottom of bottom sphere basically.The steel pipe chimb is above is partly with external screw thread; Edge, sphere upper edge, fuel tank bottom evenly distributes and is welding three legs, and whole stove and accessory is stood on the supporting surface.The top of fuel tank is a round basin shape housing that has annular sideband, and a circular hole is arranged at the bottom, and diameter is half of diameter at the bottom of the whole basin.To justify on the top sphere that basin shape housing is fixed on fuel tank by three supporting screws, be uniform-distribution with three movable supporting pawls on the annular sideband, for putting pot, spoon usefulness.On the periphery of circle basin housing bottom circular hole, three support chips of being fixed by screw are being set equably, supporting the burner of combustion chamber part, connect by screw between them, burner itself then be the cylindrical copper coin coaxial package that differs of two thicknesses together, top and bottom link together with copper coin again, it is 1.2 millimeters equally distributed flame holes that 24 diameters are arranged on the oblique connecting plate of the outer wall in top, and on the cylindrical copper coin of the inside, it is 1.2 millimeters preheating flame hole that upper and lower two circles are uniform-distribution with six diameters on every circle.

The middle coaxial evaporimeter that is equipped with of burner, it is a copper pipe that the mouth of pipe is bound by sphere,, there is internal thread at the pipe end, is screwed on the externally threaded tube head of steel pipe chimb top band of fuel tank, and the overhead height after tightening is consistent with the burner overhead height or higher slightly; Cotton thread and filament are fitly filled in along central axis direction in evaporimeter inside, both are the fasciculations that mix equably, length is from the Guan Dingzhi pipe end, connects tubule and then pass burner outer wall by tubule again by the control valve of being with handle at steel pipe chimb place opening in addition to enter burner.

When using stove and accessory, splash into the synthetic fuel of some earlier at the lower concave part of fuel tank, make the evaporimeter preheating after lighting, fuel begins vaporization, and combustion gas is by tubule, and control valve burns in burner; Along with the carrying out of combustion process, cotton thread in the evaporimeter and fine wire are intrafascicular to quicken vaporization owing to the contained synthetic fuel of capillarity is heated.This combustion gas constantly feeds burner and burns, and fine wire can constantly import heat in the fuel, has also quickened the process of vaporization; Fuel has obtained vaporizing fully and burning in other words, has reached both fuel savings, has kept pressure to burn equably again.

Now pass through the concrete structure of embodiment open oven tool.

Accompanying drawing 1--is the front view of stove and accessory;
