Abstract
The utility model relates to a spectrum analysis heating tool, in particular to a combustion-supporting type fire spraying and heating device adapting to a sample of an oxide impurity in melted low alloy steel in spectrum analysis. The combustion-supporting type fire spraying and heating device comprises a gas channel center pipe with a combustion-supporting device, wherein the combustion-supporting device is an air flow increasing sleeve arranged at the periphery of the center pipe; a gap is arranged between the air flow increasing sleeve and the center pipe; the lower part is larger than the upper part of the air flow increasing sleeve, a flow guide hole is arranged at the bottom end of the air flow increasing sleeve, and the bottom part of the air flow increasing sleeve is connected with the gas channel center pipe in a sealing way. The combustion-supporting type fire spraying and heating device can generate relative negative pressure through the high-speed spraying of gas, so that such combustion-supporting gases as air, oxygen and the like can quickly enter flames to achieve the combustion-supporting effect; in this case, the heat efficiency of a spray nozzle is increased, the oxygen consumption is saved and the cost is reduced.

Description of drawings
By the description of carrying out below in conjunction with the accompanying drawing that embodiment exemplarily is shown, above-mentioned and other purposes of the present utility model and characteristics will become apparent, wherein:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1 is that central tube, 2 is that the incremental sleeve pipe of air, 3 is pod apertures.
The specific embodiment
Below, describe burning-assist flame heater of the present utility model in detail with reference to accompanying drawing.
With reference to Fig. 1, comprise central tube 1 according to flame heater of the present utility model as blast tube, around central tube 1, be provided with auxiliary combustion equipment, thereby described auxiliary combustion equipment is to utilize negative pressure to improve air mass flow to realize the incremental sleeve pipe 2 of combustion-supporting air, is provided with the space between incremental sleeve pipe 2 of described air and the central tube 1.Central tube 1 is the tapered tubular structure, and its external diameter is less than the internal diameter of the incremental sleeve pipe 2 of air, and the bottom of the incremental sleeve pipe 2 of air is provided with 4 pod apertures 3 greater than top in the bottom of the incremental sleeve pipe 1 of air.The bottom of the incremental sleeve pipe 2 of air and the periphery fixed seal connection of passing through its middle central tube 1; Simultaneously, in order to strengthen the negative pressure effect, the top of the incremental sleeve pipe 2 of air equals or a little more than the top of central tube 1.Air enters the flow of the incremental sleeve pipe 2 of air when strengthening negative pressure, and pod apertures 3 can be provided with 3 to 5, and evenly is arranged on the circumference of the incremental sleeve pipe of air 2 bottoms.Central tube 1 and auxiliary combustion equipment can be made of refractory material, are preferably fireproof glass.
The utility model is provided with the incremental sleeve pipe 2 of the air that can play " covering combustion air " around the central tube 1 as main blast tube, during the fuel gas buring of central tube 1 upper end, space between central tube 1 and the incremental sleeve pipe 2 of air forms negative pressure, thereby impel air to enter the incremental sleeve pipe 2 of air and rise to the top and combustion gas mixing realizes combustion-supporting by pod apertures 3, the speed that the fierce more then air of the burning of central tube 1 upper port covers is fast more, and the burning of combustion gas is also abundant more.Realize effectively improving the thermal efficiency of shower nozzle with this, the consumption of conserve oxygen has reduced cost, and the utility model is simple in structure, easy to operate, remarkably productive, be suitable for applying.
The utility model is not limited to the foregoing description, under the situation that does not break away from the utility model scope, can carry out various changes and modifications, and these variations all belong to protection domain of the present utility model.
