As shown in fig. 1 to 3, a burning gun for a kiln comprises an inner tube 1 and an outer tube 2, wherein the outer tube 2 is sleeved outside the inner tube 1, and an annular channel 3 is formed between the inner wall of the outer tube 2 and the inner wall of the inner tube 1; still include injection cylinder 4 on this outer tube 2 right side of fixed connection, the right-hand member lid in this outer tube 2 has closed shrouding 21, and the through-hole that the right-hand member of this inner tube 1 set up through this shrouding 21 extends to this injection cylinder 4 in, and this shrouding 21 is provided with the natural gas through-hole 22 that sets up towards the slope of this inner tube 1 direction, and this inner tube 1 that is located injection cylinder 4 is provided with the oxygen through-hole 11 towards this shrouding 21 direction and has a plurality of rotor blade 13 that become the tangent line equipartition of angle of inclination to rotate and connect.
With the solution of the present embodiment, the right end of the inner tube 1 extends into the injection cylinder 4 through the through hole of the closing plate 21. Thus, the natural gas and the oxygen are only mixed in the injection cylinder 4, but are not mixed in advance in the annular channel 3 and the inner pipe 1, only the natural gas is introduced into the annular channel 3, and only the oxygen is introduced into the inner pipe 1; the utility model can control the natural gas and the oxygen to be mixed only in the injection cylinder 4 without mixing in advance, so that the contact area of the natural gas and the oxygen is greatly reduced, the combustion cannot be spread into the annular channel 3 and the inner tube 1 after the mixed gas is ignited, and the explosion in the annular channel 3 and the inner tube 1 is avoided, thereby generating danger to a workshop of the kiln.

In the present embodiment, each rotor blade 13 is tangentially spaced at an elevation angle of 25-45 °. Thus, the arrangement can lead the mixed gas to flow spirally along the inner wall of the injection cylinder 4, and the size of the spiral outer diameter of the spiral flow can be controlled by an elevation tangent of 25-45 degrees. Optionally, each of the rotor blades 13 is tangentially spaced at an elevation angle of 45 °. Thus, the spiral outer diameter of the mixed gas flowing spirally along the inner wall of the injection cylinder 4 is the largest, so that the natural gas and the oxygen can be mixed more uniformly, and the combustible gas can be combusted more completely.
Specifically, the natural gas passage hole 22 is shaped as a parallelogram. Thus, the arrangement can increase the ventilation quantity of the natural gas through hole 22, and avoid unnecessary blockage in the process of conveying natural gas. Alternatively, the natural gas passage hole 22 may be also provided in an elliptical, rectangular or kidney shape.
As shown in fig. 2 and 3, the outer tube 2 is communicated with a natural gas inlet passage 23, the inner tube 1 is communicated with an oxygen inlet passage 12, and the natural gas inlet passage 23 and the oxygen inlet passage 12 are vertically arranged. Thus, the natural gas inlet channel 23 and the oxygen inlet channel 12 are arranged at 90 degrees, and natural gas and oxygen can be conveyed to the gas transmission device from different directions in the actual gas transmission process, so that the gas transmission device is convenient for workers to distinguish and install. Alternatively, the angle between the natural gas intake passage 23 and the oxygen intake passage 12 may also be set to 45 °.
Further, a sealing ring is fixedly connected between the through hole of the closing plate 21 and the inner tube 1. Thus, a seal is formed between the inner tube 1 and the sealing plate 21, so that the natural gas cannot leak from the gap between the inner tube 1 and the sealing plate 21, and the natural gas is ensured to be sprayed out from the natural gas through hole 22 and sufficiently mixed with oxygen. It should be noted that the sealing ring is a rubber ring. Alternatively, the rubber ring can adopt an NBR nitrile rubber sealing ring, which can reduce the manufacturing cost; HNBR hydrogenated nitrile rubber sealing rings can also be adopted, so that better abrasion resistance is achieved; SIL silicone rubber sealing rings or VITON fluorine rubber sealing rings can also be adopted, and the heat-resistant and high-temperature-resistant performance is good.
