Abstract

The utility model discloses a liquefied gas mixed burner used for domestic cookers, comprising a combustion head, an igniter, a preheater, a liquefied gas steel cylinder, and a gas-liquid mixer, wherein, the preheater is fixed between the combustion head and the igniter. The gas-liquid mixer installed in the liquefied gas steel cylinder is composed of a liquid inlet joint, a gas inlet pipe and a gas outlet joint which are fixedly connected and combined in sequence. When the utility model is used, the preheater is directly preheated, the liquefied gas is mixed thoroughly and is combusted thoroughly, no liquid is accumulated or leaked in a pipeline, and the operation is convenient and safe.

Description

Liquefied gas mixes burning device

The utility model relates to a kind of liquefied gas and mixes burning device, the liquefied gas mixed combustion apparatus that especially a kind of family expenses kitchen range use.

At present, in order to make with carbon five is that the new liquid synthetic fuel of primary raw material is easily lighted on the family expenses kitchen range and more fully burning, and installed preheater between the combustion head of the mixed burning device that kitchen range are supporting bottom or two combustion heads, be provided with Liqiud-gas mixing device in the cylinder for liquefied gas.Yet because preheater can not directly utilize the burning preheating of liquefied gas self, so the igniting in winter often must be by the burner indirect preheating of alcolhol burner and so on, and it is convenient inadequately to use.In addition, the Liqiud-gas mixing device in the steel cylinder has only a major part, and inlet, air admission hole, venthole are close, and blending space is narrow and small, thereby gas-liquid is difficult to mixed on demand, can't guarantee in abundant vaporization, burning and the pipeline of liquefied gas not hydrops, dropping liquid.

The purpose of this utility model is the deficiency that exists at prior art, provides a kind ofly can directly utilize liquefied gas self burning preheating, and guarantees that gas-liquid is rationally mixed, fully the liquefied gas of vaporization combustion mixes burning device, avoids hydrops, dropping liquid.

Liquefied gas of the present utility model mixes burning device and includes combustion head, igniter, preheater, cylinder for liquefied gas, Liqiud-gas mixing device, and preheater is fixed between combustion head and the igniter.Be installed in the vapour-liquid mixing arrangement in the cylinder for liquefied gas, by liquid inlet joint, air inlet pipe, go out the vapour joint and be connected according to the order of sequence and combine.

Advantage of the present utility model is: because preheater is between combustion head and igniter, the flame that sprays to combustion head by igniter during igniting can play the effect of direct heating preheater, need not to adopt other burner indirect preheating, thereby easy to use.In addition, air inlet pipe in the vapour-liquid mixing arrangement has been drawn back the distance of inlet, air admission hole, venthole, increased the vapour-liquid blending space, guaranteed the reasonable mixing of gas-liquid in steel cylinder, liquefied gas is in time heated after entering preheater in addition, fully vaporization, therefore, burning has overcome the hydrops in the pipeline, dropping liquid, the unsafe factor of having avoided dropping liquid to bring to use fully.

Describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the schematic diagram of an embodiment of the utility model.

Steel cylinder 5 interior contains are the liquefied synthetic fuel of primary raw material with carbon five among Fig. 1, steel cylinder steam outlet pipe 10 is connected to the inlet pipe 4 of the preheater 2 that the red copper material makes, inlet pipe 4 is coiled on the combustion head 3, preheater 2 is cylindric, be fixed between combustion head 3 and the igniter 1 by inlet pipe 4, go out pipe 9 and radially insert preheater, arrive at its upper inside wall, and be connected with the preheater sealing from the bottom.Liqiud-gas mixing device in the steel cylinder is by liquid inlet joint 6, air inlet pipe 7 and go out vapour joint 8 and combine by being threaded, the air admission hole 11 on the inlet opening on the liquid inlet joint 6, the air inlet pipe 7 and go out vapor opening aperture coupling mutually as required on the vapour joint 8.

After opening the valve of cylinder for liquefied gas 5, liquid fuel enters air inlet pipe 7 from liquid inlet joint 6, mix with gas from air admission hole 11, and tentatively vaporization enters escape pipe 10 and inlet pipe 4 after go out vapour joint 8, then arrives in the preheater 2.In addition, a little liquid fuel of fully not vaporizing will accumulate in the preheater bottom, and can not enter out in the pipe 9, thereby avoid the hydrops in the pipeline, leakage.During igniting, flame heats preheater in spraying to the combustion head way, after combustion head 3 is lighted, heat can be transmitted to inlet pipe 4 and the preheater 2 that coils on it, make so further abundant vaporization of fuel from go out pipe 9, to enter combustion head again, guaranteed the complete and abundant of burning, easy to use, safe, even in the winter time also can operate as normal.
