The movable pot holder is positioned on a cover casing of the fuel tank, the lamp wick assembly is arranged in the center of the cover casing and in the movable pot holder, and a thermal insulation fiber blanket layer is clamped in the middle of the cover casing. The lamp wick assembly comprises a lamp wick seat connected with the cover casing and double ceramic sleeves installed on the lamp wick seat, wherein the double ceramic sleeves comprises an outer location ceramic sleeve and an inner lamp wick ceramic sleeve which are in clearance fit, the outer location ceramic sleeve is connected onto the lamp wick seat, a lamp wick is arranged in the inner lamp wick ceramic sleeve, and the lamp wick is a cylinder body formed by wrapping and clamping an outer layer of thermal insulation fiber blanket layer on an inner layer of cotton thread layer. The anti-explosion liquid-fuel small stove effectively reduces heat of the lamp wick to be transferred on the ceramic sleeves, the ceramic sleeves can effectively prevent heat from being transferred to the cover casing, the thermal insulation fiber blanket layer in the middle of the cover casing can effectively prevent flame radiation heat of the lamp wick from being transferred to fuel in the fuel tank, and explosion hazards of the fuel tank is completely eliminated by building air exhaust balance of the fuel tank.
Description
(1) technical field:
The present invention relates to cooking stove, be specially a kind of explosion-proof liquid fuel small furnace.
(2) background technology:
Small furnaces such as the current liquid alcohol that at the restaurant, uses in the restaurant, kerosene also have the used alcolhol burner in school laboratory, because the heat of wick flame passes to fuel tank easily during burning, fuel tank fuel temperature are raise, and the hidden danger of blasting is arranged.
" a kind of small furnace of firepower adjustable size " utility model patent (patent No. is ZL201020525855.3) like the applicant's application; Can realize firepower adjustable size in the use; But do not solve the user when using for a long time the wick flame heat regulating conduct to fuel tank and cause that fuel temperature raises, and exists potential safety hazard.
(3) summary of the invention:
The technical problem that the explosion-proof liquid fuel small furnace of the present invention will solve is: intercept the wick flame heat regulating and conduct to fuel tank, avoid causing that fuel temperature raises, thereby eliminate the hidden peril of explosion that heat transmission causes.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
The explosion-proof liquid fuel small furnace of the present invention comprises fuel tank, moveable pot frame and wick assembly; Said moveable pot frame is erected on the shell of top cover of fuel tank; Said wick assembly is located at and is covered the shell center and be in the moveable pot frame, and different is that said lid shell therebetween is provided with heat insulation tapetum fibrosum; Said wick assembly comprises the wick holder that is connected with the lid shell and is installed on the two porcelain bushings on the wick holder; Said pair of outside fix porcelain bushing and the interior wick porcelain bushing that porcelain bushing is a matched in clearance; Said outside fix porcelain bushing is connected on the wick holder; Be equipped with wick in the interior wick porcelain bushing, said wick is the cylindrical shell that outer heat insulation tapetum fibrosum double team internal layer cotton thread layer is rolled into.
Taked four kinds of measures to eliminate the hidden peril of explosion that heat transmission causes in the technical scheme of the present invention.
1, adopts two porcelain bushings that wick is installed, utilize the hot characteristics of transmitting of high temperature resistant and effective deadening of ceramic material, prevent that effectively heat is delivered to the fuel tank cap shell.
2, the heat that the outer heat insulation tapetum fibrosum double team internal layer cotton thread layer (adsorption capacity that cotton thread is stronger is drawn onto wick top with liquid fuel and lights) of wick, outer heat insulation tapetum fibrosum can effectively reduce wick is transmitted on the interior wick porcelain bushing.
3, be provided with heat insulation tapetum fibrosum in the interlayer of fuel tank cap shell, can deaden the heat that the wick flame thermal radiation is transmitted on the fuel tank, prevent fuel heating causing intensification is caused quickening volatilization, eliminate hidden peril of explosion.
4, outside fix porcelain bushing and interior wick porcelain bushing matched in clearance have solved the exhaust equilibrium problem of fuel tank, eliminate hidden peril of explosion.
Said wick assembly also comprise can be upper and lower move in the wick governor motion of wick porcelain bushing, make the present invention become the explosion-proof liquid fuel small furnace of scalable firepower size.
The present invention who does not dispose the wick governor motion then is the fixing explosion-proof liquid fuel small furnace of firepower.
The kind of drive that said wick governor motion generally adopts is the rack-and-pinion transmission; Said tooth bar is located on the interior wick porcelain bushing; Said gear is located on the wick holder; Gear is through opening on the outside fix porcelain bushing and tooth bar engagement, and the positive and negative rotation of gear can realize the rise and the reduction of interior wick porcelain bushing, thus the regulation and control of control firepower size.
Reasonable fit clearance between said outside fix porcelain bushing and the interior wick porcelain bushing is set at 0.3mm～0.7mm.
Said wick top is provided with the stainless (steel) wire protective cover.
The act as a fuel fuel of case of the screw thread screw socket that said lid shell is connected with wick holder adds inlet.
It is CY1600 (anti-1600 ℃ of high temperature) that said heat insulation tapetum fibrosum is selected model for use, Al wherein
2O
3+ SiO
2Chemical constituent accounts for 99.5%.
Compared with prior art, the invention has the advantages that:
1, wick is rolled into cylindric processing by heat insulation tapetum fibrosum and cotton thread layer, and cotton thread has utilized the stronger adsorption capacity of cotton thread as internal layer, liquid fuel is drawn onto wick top lights; Heat insulation tapetum fibrosum is transmitted on the interior porcelain bushing as the heat that skin can effectively reduce wick.
2, adopt two porcelain bushings to fix wick, the utilization pottery is high temperature resistant and the characteristic of low-thermal conductivity, and the heat that significantly reduces wick flame is passed to the liquid fuel in the fuel tank through sleeve pipe, effectively prevents to heat up; Keep reasonable supporting clearance between inner sleeve and the outer tube, solved the exhaust equilibrium problem of fuel tank, eliminate hidden peril of explosion.
3, the lid shell of fuel tank is a sandwich, and the centre is provided with heat insulation tapetum fibrosum, can be transmitted to the wick flame thermal radiation heat deadening of fuel tank, prevents fuel heating causing intensification to be caused quickening volatilization, the elimination hidden peril of explosion.
4, can select firepower size adjustment mechanism as required, can select does not have firepower size adjustment mechanism yet.
5, the present invention cooperates the liquid alcohol radical bio-fuel use that the applicant researches and develops, and combustion product is main with water vapour, and three-waste free discharge is favourable to environment and health.
