Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 to 3, the utility model discloses a stick type naked light burner, include gas pipeline 2 and the air duct 3 that joins at venturi mixer 1, connect the hybrid tube 4 of 1 export of venturi mixer and connect a plurality of hollow burning stick 5 on hybrid tube 4, be equipped with ignition electrode (not drawn) by ignition control device 6 control in the burning stick 5, the outside of burning stick 5 has the air chamber board 51 of four rectangular shapes around the axle equipartition, air chamber board 51 separates the lateral wall of burning stick 5 into a plurality of poroses regions (not mark), the centre of porose region becomes to be listed as and has seted up a plurality of main blowholes 52. The device is used by inserting the burning rod 5 into the back of the mold 7. The gas and the air reach the Venturi mixer 1 through the gas pipeline 2 and the air pipeline 3 respectively for mixing, then are conveyed into the combustion rod 5, and are ignited by the ignition electrode to carry out primary combustion; the structure of the combustion rod 5 can cause four air-exhaust mixed gas spraying positions, the air chamber plate 51 can divide the periphery of the combustion rod 5 into slender air chambers, and the air-fuel mixed gas meets the peripheral air to generate secondary combustion to generate more uniform combustion flame, so that the mold 7 is efficiently and uniformly heated. Since the chamber plates 51 are only for dividing the periphery of the combustion rod 5 into uniform chambers, the number of the chamber plates 51 can be arbitrarily adjusted to three or more in practical use, and the shape of the chamber plates 51 is not limited to the flat plate structure in the embodiment.
