Description

[Detailed description of the invention] This invention is an improvement to the ignition electrode in a gun-type burner, making it easier to install and remove the ignition electrode, making inspection, repair, and cleaning easier. This will be explained in detail.

Reference numeral 1 indicates a gun type burner, and the burner 1 has a fan casing 2 containing a blower (not shown), a proa tube 5 having an ignition electrode 3 and a fuel spray nozzle 4 arranged at its tip opening, and a frame holder 6. It consists of a tube 7.

The proa tube 5 is provided with a flange 9 around the proximal opening 8, and a nozzle holder 11 into which a fuel conduit 10 leading to the nozzle 4 is inserted and held is integrally formed with the proa tube 5 together with a support rod 12. It's intimidating.

The nozzle holder 11 is provided with an engagement groove 13 from its base end 11a to near the tip 11b, while the proa tube 5 has a mounting hole 1 continuous with the opening 8 at the opening 8.
4 is provided.

15 has an ignition electrode 3, which is connected to the engagement groove 1 of the holder 11;
The insulator 15 is an electrode insulator having a tongue piece 16 that engages with the holder 1 fixed to the outer wall of the proa tube 5.
7 and is connected by an electrode wire 18.

Reference numeral 19 denotes a mounting flange of the holder 17, which is mounted to the outer wall of the proa tube 5 with screws 20 or the like.

21 is an electrode cord, and 22 is a flange of the fan casing 2 which is flange-connected to the proa tube 5.

Furthermore, the holder 17 and the electrode insulator 15 are in the attached state (second
The angle θ is set to be wider than the angle θ′ shown in the figure.

The present invention has the above-mentioned configuration, and the burner 1 is assembled by inserting the fuel conduit 10 into the nozzle holder 11, attaching the fuel spray nozzle 4, and inserting the tongue piece 16 of the next electrode insulator 15 into the groove 13 at the base of the nozzle holder 11. Fit the holder 17 from the end 11a into the mounting hole 14 through the opening 8 of the tube 5, slide the holder 17 and the electrode insulator 15 toward the distal end of the proa tube 5, and insert the holder 17 into the tube 5 at the end of the mounting hole 14. Fix it to the outer wall with screws 20, etc.

Then, the burner tube 7 is connected to the tip of the proa tube 5, and the fan casing 2 is connected to the flange 9 of the tube 5.

Therefore, according to the present invention, there is no need to fix the electrode insulator 15 to the nozzle holder 11 with screws or the like as in the conventional case, and the work of fixing it inside the proa tube 5 can be omitted, making it extremely easy to attach and detach the ignition electrode. I can do it.

Moreover, the ignition electrode 3 has a large effect on the ignitability of the burner.
The vertical position of the nozzle holder 11 is regulated by the groove 13 and the tongue piece 16, and the horizontal direction is regulated by the holder 1.
By fixing the electrode insulator 7, the electrode insulator 15 is pressed against the holder 11 through the tongue piece 16 and is regulated, thereby being reliably held at a proper position.

That is, to further discuss the positional regulation in the left and right direction, as can be seen by comparing FIG. 4 and FIG. When attaching the insulator 15, the electrode wire produces a spring effect and strongly presses the insulator 15 against the nozzle holder 11.

As described above, the present invention eliminates the need for fixing the ignition electrode inside the proa tube, which was conventionally done, so the ignition electrode can be attached and removed very easily. It is held in an appropriate position and will not be distorted by shock during transportation.
