Abstract
The utility model discloses a spray gun, which consists of an atomization air pipe (1), a fuel pipe (2), a fuel gun air pipe (4), a fuel gun (5) and a fuel gun oil pipe (6). Moreover, the spray gun is characterized in that the atomization air pipe (1) is connected with a standby fuel gun air pipe (9) through a standby air switch (8); the fuel pipe (2) is connected with a standby fuel gun oil pipe (11) through a standby fuel switch (10); the standby fuel gun air pipe (9) and the standby fuel gun oil pipe (11) are connected with a standby fuel gun (12); therefore, during the using process of the fuel gun, if the fuel gun is needed to be cleaned or replaced in case of failure, a fuel oil gun in use is only required to be removed, and then a standby fuel oil gun is assembled; then the normal supply of the fuel oil can be resumed immediately. The spray gun is suitable to be used for fuel oil, additive and raw oil during carbon black production.
Description
Technical field:
The utility model relates to a kind of spray gun, the spray gun that fuel oil, additive, feedstock oil are used in particularly a kind of production of carbon black.
Background technology:
At present, the fuel oil that uses is gone into stove injection apparatus-oily spray gun now, operation principle is that fuel oil enters mixing chamber by central tube, mixes back atomizing ejection burning with compressed air from the external jacket layer, and the heat energy of continous-stable is provided for the feedstock oil cracking of producing carbon black.But the obstruction of fuel oil shower nozzle, compressed air orifice blocking problem can appear in this fuel oil injection mode in production run, influence the fuel oil combustion heating effect, even can damage the combustion chamber; When this situation occurring, must clear up or refuelling oil spray gun, consuming time generally at 30 minutes, stove is gone in fuel oil stop supplies during this, produce the required only remaining physics heat of bringing into by air after the preheating of heat of feedstock oil cracking of carbon black, cause carbon black products off quality.
Summary of the invention:
The purpose of this utility model is exactly will provide a kind of must shorten the refuelling oil used time of spray gun as far as possible, reduces the spray gun to the influence of carbon black products quality significantly.
The purpose of this utility model is achieved in that a kind of spray gun, form by atomized air tube, fuel pipe, oil combustion gun air hose, oil combustion gun, oil combustion gun oil pipe, it is characterized in that being connected with reserve fuel rifle air hose by standby air switch on the described atomized air tube, connect reserve fuel gun oil pipe by the reserve fuel switch on the fuel pipe, reserve fuel rifle air hose is connected with the reserve fuel rifle with reserve fuel gun oil pipe.
The utility model compared with prior art has the following advantages:
Be connected with reserve fuel rifle air hose by standby air switch owing to adopted on the atomized air tube, connect reserve fuel gun oil pipe by the reserve fuel switch on the fuel pipe, the version that reserve fuel rifle air hose and reserve fuel gun oil pipe are connected with the reserve fuel rifle respectively, thereby, must shorten the refuelling oil used time of spray gun as far as possible, reduce influence significantly the carbon black products quality.
Description of drawings:
Accompanying drawing is the utility model concrete structure schematic diagram

5, oil combustion gun 6, oil combustion gun oil pipe 7, oil combustion gun fuel line cock 8, standby air switch
9, reserve fuel rifle air hose 10, reserve fuel switch 11, reserve fuel gun oil pipe
12, reserve fuel rifle
The specific embodiment:
Atomized air tube 1 connects an end of oil combustion gun air hose 4 by oil combustion gun air hose switch 3, the other end of oil combustion gun air hose 4 connects oil combustion gun 5, simultaneously, an end that also connects reserve fuel rifle air hose 9 on the atomized air tube 1 by standby air switch 8, the other end of reserve fuel rifle air hose 9 connects reserve fuel rifle 12, fuel pipe 2 is connected with an end of oil combustion gun oil pipe 6 by oil combustion gun fuel line cock 7, the other end of oil combustion gun oil pipe 6 connects oil combustion gun 5, simultaneously, also be connected with an end of reserve fuel gun oil pipe 11 by reserve fuel switch 10 on the fuel pipe 2, the other end of reserve fuel gun oil pipe 11 connects reserve fuel rifle 12.
During use, in the oil combustion gun use if fault need be cleared up or when changing oil combustion gun, only need and to withdraw from the fuel oil gun, again the reserve fuel rifle is installed at once, the normal supply that just can recover fuel oil at once, so just the consuming time of cleaning or refuelling oil spray gun can be foreshortened to 3-5 minute by 30 minutes, it is very short that time of stove is gone in fuel oil stop supplies during this, can not influence the quality of carbon black products.
Claims (1)
1. spray gun, form by atomized air tube (1), fuel pipe (2), oil combustion gun air hose (4), oil combustion gun (5), oil combustion gun oil pipe (6), it is characterized in that described atomized air tube (1) upward is connected with reserve fuel rifle air hose (9) by standby air switch (8), fuel pipe (2) is gone up by reserve fuel switch (10) and is connected reserve fuel gun oil pipe (11), and reserve fuel rifle air hose (9) is connected with reserve fuel rifle (12) with reserve fuel gun oil pipe (11).
