Description
Technical field:
The utility model relates to fuel Oil gun head, particularly a kind of new-type carbon black fuel Oil gun head.
Background technology:
Current production of carbon black producer often uses coke-stove gas alternative fuel oil, for carbon black combustion chambers burn, for carbon black cracking reaction provides high temperature, but it is not high to be limited to coke-oven plant's coke-stove gas output, be not enough to the Production requirement meeting production of carbon black producer, in order to meet Production requirement, production of carbon black producer generally adopts fuel oil combustion to provide high temperature for carbon black cracking reaction.Fuel oil is when carbon black combustion chambers burn, and the general fuel Oil gun head that passes through by fuel oil atomization, and burns, to make fuel oil Thorough combustion; But existing fuel Oil gun head is when fuel oil flow is large, compressed air supply wretched insufficiency, causes fuel oil atomization weak effect, thus adds the burning time of fuel oil; Because atomizing effect is bad, the comparatively larger oil droplet of generation can not Thorough combustion, easily produces tiny burnt grain, affects carbon black mass.
In order to solve the problem, generally can the aperture of increasing fuel Oil gun head nozzle opening, but due to the restriction of fuel Oil gun head appearance and size, the interval between rifle head nozzle opening aperture is caused to reduce, in high temperature production, the fuel oil of Yin Gaowen large discharge constantly washes away, and causes rifle head nozzle opening aperture can be increasing, spray patterns is unbalance, affect carbon black mass, the serious rifle head that even there will be burns out or obscission, causes damage to combustion chamber, shorten combustion chamber service life, increase production cost.
Utility model content:
The purpose of this utility model is to provide a kind of new-type carbon black fuel Oil gun head strengthening fuel oil atomization effect, temperature carbon black products quality.
The utility model is implemented by following technical scheme: new-type carbon black fuel Oil gun head, it comprises fuel feed tube and rifle head shell, described fuel feed tube and described rifle head shell are blind hole pipe, described fuel feed tube is set in described rifle head shell, and the cavity formed between the blind end of described fuel feed tube and the blind end of described rifle head shell is mixing chamber; The openend inwall of described fuel feed tube is provided with internal thread, some spiral ducts are provided with between the lateral wall of described fuel feed tube and the inwall of described rifle head shell, the air inlet of described spiral duct is in communication with the outside, the air outlet of described spiral duct is communicated with described mixing chamber, and the corresponding each air outlet place of described fuel feed tube blind end is provided with an oil-out; The openend outer wall of described rifle head shell is provided with external screw thread, and the blind end end face of described rifle head shell is radially evenly placed with several jets circlewise.
Preferably, have angle α between the axis of each described jet and described rifle head housing axis, described angle α is 15 °-35 °.
Advantage of the present utility model: increase some spiral ducts, the air outlet of every bar spiral duct goes out correspondence and is provided with jet, fuel oil fully can be mixed with compressed air and spray at a high speed, and being fully atomized in mixing chamber, strengthen fuel oil atomization effect, ensure carbon black products quality.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Fig. 4 is the utility model using state schematic diagram.

Detailed description of the invention:
As Figure 1-4, new-type carbon black fuel Oil gun head, it comprises fuel feed tube 1 and rifle head shell 2, and fuel feed tube 1 and rifle head shell 2 are blind hole pipe, fuel feed tube 1 is set in rifle head shell 2, and the cavity formed between the blind end of fuel feed tube 1 and the blind end of rifle head shell 2 is mixing chamber 3; The openend inwall of fuel feed tube 1 is provided with internal thread 4, some spiral ducts 5 are provided with between the lateral wall of fuel feed tube 1 and the inwall of rifle head shell 2, the air inlet 6 of spiral duct 5 is in communication with the outside, the air outlet 7 of spiral duct 5 is communicated with mixing chamber 3, and corresponding each air outlet 7 place of fuel feed tube 1 blind end is provided with an oil-out 8; The openend outer wall of rifle head shell 2 is provided with external screw thread 9, and the blind end end face of fuel feed tube 1 is radially evenly placed with six jets 10, and have angle α between the axis of each jet 10 and rifle head shell 2 axis, angle α is 15 °-35 °.
Using method: fuel(l)ing oil hose 12 is spirally connected by internal thread 4 and fuel feed tube 1, compression airduct 11 is spirally connected by external screw thread 9 and rifle head shell 2, after installation, in fuel feed tube 1, fuel oil is passed into by fuel(l)ing oil hose 12, pass into compress wind by compression airduct 11 to spiral duct 5, fuel oil is flowed out by oil-out 8, and compress wind has spiral duct 5 air outlet 7 to blow out, compress wind is brought the fuel oil that oil-out 8 flows out into mixing chamber 3 and is atomized, and the fuel oil after atomization is sprayed by jet 10.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
