DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3 The utility model provides a technical solution: a natural gas bottle kiln, comprising a kiln wall 2, a positioning slide plate 7, a positioning slide groove 8, an igniter 9, a heat-insulating box body 10, a movable plate 11, a movable rod 12 and an electric push rod 13, a smoke exhaust port 1 is provided on the upper end surface of the kiln wall 2, a support plate 3 is fixed on the lower end surface of the kiln wall 2, and support feet 4 are fixed on the three corners of the lower end surface of the support plate 3, an air intake pipe 5 is fixed on the left end surface of the kiln wall 2, a natural gas intake pipe 14 is fixed on the right end surface of the kiln wall 2, and a furnace grate 6 is fixed inside the kiln wall 2;

[0020] An electric push rod 13 is fixed to the lower end surface of the support plate 3, and a movable rod 12 is installed at the output end of the electric push rod 13. A movable plate 11 is fixed to the upper end surface of the movable rod 12. Positioning slide grooves 8 are opened inside the kiln wall 2. The positioning slide grooves 8 are slidably connected with positioning slide plates 7. An insulating box body 10 is fixed between the positioning slide plates 7. An igniter 9 is fixed to the upper end surface of the movable plate 11 and extends out of the insulating box body 10. This design can drive the igniter 9 to retract into the insulating box body 10 through the electric push rod 13, so that the igniter 9 is away from the combustion area of ​​air and natural gas, thereby improving the service life of the igniter 9.

[0021] As the first embodiment of the utility model: the specification of the positioning slide 8 matches the specification of the positioning slide plate 7, and the two can be fitted and slidably connected. The design makes the up and down movement of the heat insulation box body 10 more stable through the fitting and sliding connection of the positioning slide 8 and the positioning slide plate 7. The support plate 3 and the furnace wall 2 are both provided with movable holes. The inner diameter of the movable hole is equal to the outer diameter of the movable rod 12, and the two can be fitted and slidably connected. The design can drive the movable rod 12 to extend into the furnace wall 2 through the electric push rod 13, so that the movable rod 12 can drive the movable plate 11 to move up and down;
