Abstract

The utility model relates to a fuel carburetor for domestic liquid fuel stoves, which is provided with a liquid inlet pipe 1, a steam chamber 2 and a steam supply pipe 3 communicated with the steam chamber; the steam chamber is communicated with the upper ends of a plurality of vaporization pipes 4 which are vertically arranged into a birdcage shape; the lower ends of the vaporization pipes are communicated with the pipe body of a helical mother liquid pipe 5; one end of the mother liquid pipe is communicated with the liquid inlet pipe, and the other end is communicated with a balance pipe. The radiant heat of a burner is used to vaporize liquid fuel, which can save vaporization fuel; the heat exchange area of the vaporization pipe is enlarged; the vaporization efficiency is improved; the part of burning stream which is led to the enclosed type fuel tank of the burner by the balance pipe plays the role of automatic pressure increasing, thus outer pressure is not needed; the burner has good burning stability.

Description

Liquid fuel stove core with evaporation burner

The utility model relates to the fuel vaporizer of household liquids fuel burner.

The fuel vaporizer of existing household liquids Fuel Furnace, as the kerosene gasification burner, a kind of is on the burning stone or metal plate for standing a stove on as a precaution against fire a horizontal generating tube to be set, a kind of is the vaporizer that a bottom of a pan shape is set above duration and degree of heating, steam supply pipe connects oil can and vaporizer, and steam transmitting pipe connects vaporizer and duration and degree of heating nozzle, and kerosene enters vaporizer from feed pipe, after duration and degree of heating heating vaporization, deliver to the nozzle burning by steam transmitting pipe.The vaporization poor-performing of this class vaporizer, the vaporizer heat exchange area is little, and class pressurized equipments such as need employing inflator are accelerated fuel flow rate for the fuel impressed pressure and are obtained enough evaporating capacities.

Given this, the purpose of this utility model just is to provide a kind of vaporization combustion chamber that heat exchange area improves the liquid fuel of vaporization efficency that increases.

Liquid fuel vaporizing burner core of the present utility model (as shown in drawings), the steam supply pipe (3) that comprise feed tube (1), steam chest (2), is communicated with steam chest, above-mentioned steam chest is communicated with the many upper ends that are erected to be arranged in the generating tube (4) of birdcage shape, the lower end of generating tube is communicated with mother liquor pipe (5) body of helical, and above-mentioned mother liquor Guan Yiduan is communicated with feed tube, the other end is communicated with balance pipe (6).

The utility model is installed in the burner central part of burner, liquid fuel in the enclosed fuel case through feed tube, mother liquor pipe, enter generating tube, after the high temperature heating vaporization of burned chamber, come together in steam chest, import combustion chambers burn through steam supply pipe, simultaneously, the part vaporized fuel in the mother liquor pipe imports the enclosed fuel case through balance pipe.

Liquid fuel vaporizing burner core of the present utility model has following advantage.

One, be arranged on the central part of burner, the radiation waste heat that makes full use of burner makes carburretion, can save vaporization fuel.

Two, many generating tubes of design constitute birdcage shape structure, and the heat exchange area of generating tube is big, and can try one's best near the burner duration and degree of heating, its vaporization efficency height, and the carburretion amount can satisfy the demands.Even balance pipe will partly fire vapour introduces the enclosed fuel case automatically to the fuel system supercharging, and need not to pressurize separately, and obtains the automatic transport of fuel.

Three, design helical mother liquor pipe and balance tubular construction allow the part vaporized fuel after vaporizing introduce fuel tank.Supercharging, voltage stabilizing to be guaranteeing the operate as normal of burner, no tempering, the phenomenon of breathing, and combustion stability is good.

Four, not burned device flame directly heat, long service life.

Below, use embodiment and accompanying drawing thereof again, the utility model is described in further detail.

Brief description of drawings.

Fig. 1 is the structural representation of a kind of liquid fuel vaporizing burner core of the present utility model.The many generating tubes 4 that show steam chest 2, mother liquor pipe 5, steam supply pipe 3, birdcage structure.

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.The mother liquor pipe 5, feed tube 1, the balance pipe 6 that show the spiral structure.

Fig. 3 is the B-B sectional structure schematic diagram of the steam chest of Fig. 1.Show air intake 8, venthole 7 that generating tube, steam supply pipe and steam chest are connected respectively.

Solid arrow shows that liquid fuel flows to, and dotted arrow shows that vaporized fuel flows to.

Embodiment 1

A kind of liquid fuel vaporizing burner core of the present utility model is referring to accompanying drawing.Constitute by steam chest 2, generating tube 4, steam supply pipe 3, mother liquor pipe 5, feed tube 1, balance pipe 6.The copper pipe that above-mentioned each selection for pipeline is common or other metal material pipes.

Above-mentioned steam chest 2 is made the closed circular tubular with metal, and the end welding of the center of its lower plate 9 and air supply pipe 3 is communicated with, and forms steam ports 7, around venthole, be communicated with the upper end welding of the generating tube 4 of 6 settings in uniform way, and formation air intake 8.Above-mentioned mother liquor pipe 5 is bent into helical, and trying one's best at the upper side of body is communicated with the lower end welding of above-mentioned 6 generating tubes 4 in uniform way, thereby makes 6 generating tubes arrange the structure that forms birdcage shapes.The outside port of mother liquor pipe 5 is communicated with feed tube 1 welding, and its inboard port is to weld sleekly with balance pipe 6 and is communicated with.The caliber of above-mentioned mother liquor pipe should be greater than feed tube 1, balance pipe 6, generating tube 4.

Claims

1, liquid fuel vaporizing burner core, the steam supply pipe (3) that comprise feed tube (1), steam chest (2), is communicated with steam chest, it is characterized in that above-mentioned steam chest is communicated with the many upper ends that are erected to be arranged in the generating tube (4) of birdcage shape, the lower end of generating tube is communicated with mother liquor pipe (5) body of helical, and above-mentioned mother liquor Guan Yiduan is communicated with feed tube, the other end is communicated with balance pipe (6).
