Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model being described in detail, the description of this part is only exemplary and explanatory, and protection domain of the present utility model should not have any restriction effect.

If Fig. 1 is to shown in 7, a kind of coal tar all-oxygen combustion controls system and burns rifle, adopts coaxial sleeve form design, center is outwards followed successively by: rifle core 2, the body of a gun 3, gun housing 7, adapter 8; Whole burning rifle uses resistant to elevated temperatures stainless steel material to process.

It is the fuel channel burning rifle in the middle of rifle core 2, as passed into coal tar by coal tar entrance 1; The atomization gas passage of the gap composition burning rifle that rifle core 2 is middle with the body of a gun 3, logical compression air; Gap between the body of a gun 3 and gun housing 7 is combustion-supporting gas passage, logical oxygen.

Rifle core 2 front end is the jet 13 of taper, is elongated stainless steel oil pipe in the middle of rifle core 2; Jet 13 internal diameter is less than pipe aperture, and the speed that such coal tar flows at jet 13 can increase suddenly, it is simple to the ejection of coal tar; The rear end of rifle core 2 has internal and external threads and sealing ring 10, external screw thread and sealing ring 10 to be used for connection and the sealing of rifle core 2 and the body of a gun 3; Female thread is for connecting the external oil pipe of coal tar. The jet 13 of rifle core 2 and the atomizer nozzle 15 of the body of a gun 3 are designed to taper, atomizer nozzle 15 is wrapped in jet 13, there is only small gap between the two, and coal tar is when the jet 13 of taper, the speed of flowing can increase suddenly, is so easy to the ejection of coal tar; The compression air that will be atomized device nozzle 15 ejection after coal tar jet gun core 2 is broken up, it is achieved coal tar oil atomization.

This utility model finally determines jet 13 aperture of rifle core and the parameter such as the aperture of atomizer nozzle 15 and jet angle by many experiments, guarantee that coal tar will not because of the excessive incomplete or discontinuous atomization of the too small atomization caused of flow, ensure that seriality and uniformity that coal tar is atomized, keep the stability of flame.

The body of a gun 3 front end is the atomizer nozzle 15 of the atomization gas of taper, centre is elongated rustless steel trachea, and the inner sleeve 11 being attached with gun housing 7, rear end has the atomization gas import 9 vertical with the body of a gun 3 and the body of a gun location that be connected fixing with gun housing 75 to fasten, one end of body of a gun pilot pin 5 is fixed, the other end can rotate around fixing end, can be embedded in the body of a gun locating groove 4 in gun housing 7; Body of a gun afterbody has the female thread being connected with rifle core 2.

Gun housing 7 is cylindrical shape, and first half has the circular baffle plate 16 being attached with adapter 8 and from Lock buckle 12, the body of a gun 3 can be fixed on adapter 8; Latter half of have the oxygen air inlet 6 vertical with gun housing 7 and body of a gun locating slot 4; Having two grooves on the inwall of afterbody, groove is built with two sealing rings 10.

The inner sleeve 11 of the body of a gun 3 is matched in clearance with the afterbody inwall of gun housing 7, and inner sleeve 11 can at the mating part slide anteroposterior of gun housing 7, and position is adjustable; Inner sleeve 11 and gun housing 7 are sealed by two sealing rings 10 of gun housing afterbody, it is prevented that oxygen is revealed; And the afterbody of inner sleeve 11 has the baffle plate 14 of circle, it is used for limiting the body of a gun 3 and inserts the length of gun housing 7;

Body of a gun pilot pin 5 longitudinal direction has an exhausting hole, and the body of a gun locating slot 4 in gun housing 7 transversely had a through hole, both work in coordination, and centre is plugged alignment pin and just can be regulated the body of a gun 3 and insert the length of gun housing 7, can regulate with this and burn rifle muzzle position of front and back in kiln.

Adapter 8 one end is square installing plate, adapter 8 can be fixedly installed on burner block by installing plate; The circular baffle plate of the other end of adapter 8 and gun housing 7 is worked in coordination, by gun housing 7 both sides from Lock buckle 12, it is possible to adapter 8 and gun housing 7 are fixedly connected.

Burn rifle by adjusting the flow of coal tar and atomization gas, it is possible to adjust the state of coal tar atomization, thus arriving the adjustment length of flame and flame rigidity purpose. Additionally due to the body of a gun burning rifle can move forward and backward relative to gun housing, there is certain adjusting range, so can adjust the flame root position at kiln, thus regulating flame space, bringing very big facility to the adjustment of technological parameter.

Additionally, this burning rifle body of a gun connect from Lock buckle that to make to change rifle very convenient, can reduce, in rifle fault or when needing carry out changing rifle according to technique, the time changing rifle to greatest extent, it is ensured that the stability of system work. And the rifle core 2 that can individually dismantle so that the cleaning of rifle core 2 is very convenient, the intensity reduced a staff.

The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
