[Problem that the idea aims to solve]

However, the temperature of the inner and outer cylinders that make up the combustion cylinder, especially the inner cylinder, is high during combustion and when combustion is stopped. The difference is large, and expansion and contraction are repeated accordingly. This causes the inner cylinder and outer cylinder to heat up. When the inner cylinder and the outer cylinder are penetrated and tightened with a screw, the inner cylinder and the outer cylinder are ignited. For items that fix electrical components such as plugs, tightening of electrical components such as spark plugs is difficult. If the electrical component becomes loose and may rotate, for example, if the electrical component is an ignition electrode, If the ignition electrode is too far away from or too close to the ground electrode, sparks may occur between the ignition electrode and the ground electrode. If the electrical component is a flame rod that monitors the flame, the Problems such as the flame rod coming into contact with the ground side and making it impossible to detect the flame current. arise. The object of the present invention is to obtain a liquid combustor that eliminates such problems.

[Means to solve the problem]

In order to achieve the above-mentioned problems, the present invention has developed a bottomed cylindrical combustion tube consisting of an inner cylinder and an outer cylinder. The spark plug is inserted into the inner cylinder and the outer cylinder by passing through the inner cylinder and the outer cylinder and tightening with a screw. For fixing electrical components such as It consists of

[0005]

[Effect] In the liquid combustor configured as described above, when the inner cylinder and the outer cylinder are heated, When the electrical components become loose, the electrical components will no longer rotate.

【Example】

The present invention will be explained with reference to embodiments shown in the drawings. In the drawing, 1 is a bottomed cylindrical combustion tube consisting of an inner tube 1a and an outer tube 1b, and 2 is a combustion tube inside the combustion tube. The formed combustion chamber, 3 is a hat-shaped vaporization tube provided in the combustion chamber 2, and 4 is the inside of the vaporization tube 3. The air cylinder 5 facing the air cylinder 5 indicates an air supply chamber connected to the air cylinder 4, and the vaporization cylinder 3 is A fuel scattering body 6 is provided on the upper part of the lower surface, and a fuel scattering gap 7 is provided around the lower part, This is inserted into the combustion chamber 2 by inserting it through the opening provided at the center bottom of the inner cylinder 1a and the outer cylinder 1b. It is supported on the upper end of the facing rotating shaft 8 and is provided to rotate within the combustion chamber 2. Reference numeral 9 denotes an electrical component that penetrates the inner cylinder 1a and the outer cylinder 1b and faces into the combustion chamber 2. The ignition electrode 10 indicates a ground electrode provided in the inner cylinder 1a facing the ignition electrode 9. vinegar. The carburetor 3 is rotated by a motor 11 connected to the rotating shaft 8 while the fuel is being rotated. When supplying fuel to the flying object 6, the fuel is diffused along the fuel projecting object 6 and the gas is After flowing down along the inner circumferential surface of the combustion tube 3, the fuel becomes atomized into the combustion chamber 2 from the fuel scattering gap 7. It scatters. Ignition is caused by a spark formed between the ignition electrode 9 and the ground electrode 10. If so, the fuel is combusted live within the combustion chamber 2. The combustion causes the carburetor to open. When heated, the fuel flowing down along the inner circumferential surface of the vaporization cylinder 3 evaporates and flows through the air cylinder 4. A passage formed between the inner cylinder 1a and the outer cylinder 1b by being mixed with the air supplied by the 12 and burns while ejecting from the flame hole 13 provided in the inner cylinder 1a. Transition. Up until now, there has been no particular difference from what has been previously known.

[0007] In such a device, the present invention provides a rotation stopper to the tightening part of the ignition electrode 9 as the electrical component. The device provided with the means 14 and shown in FIGS. 1 and 2 has an inner cylinder 1a and an outer cylinder 1. A screw 15 is attached to the outer periphery of the ignition electrode that passes through the side plate of b and faces into the combustion chamber 2. , tighten the ignition electrode 9 to the inner cylinder 1a and outer cylinder 1b by applying a nut 16 thereto. An embodiment is shown in which the rotation means 14 is provided in the inner cylinder 1a. The girder insertion hole 1a-1 is formed into a square hole 14a, and the insulator portion 9a of the ignition electrode 9 is formed into a square hole 14a. The periphery is formed into a square shaft 14b that fits into the insertion hole 1a-1, and the square shaft 1 is inserted into the square hole 14a. By fitting 4b, the ignition electrode 9 can be rotated even if the tightening may loosen. I made sure that it never happened.

[0008] Further, in the case shown in FIGS. 3 to 6, the screw tube 17 integrated with the ignition electrode 9 is attached to the inner tube 1a. The screw tube 17 is connected to the inner tube 1a and the outer tube with a nut 18. An embodiment is shown in which the tube 1b is tightened and fixed to the bottom plate. The rotation prevention means 14 includes an abutment piece 14c that comes into contact with the inner peripheral surface of the inner cylinder 1a and the screw cylinder 17. A seat collar is provided with a stepped portion 14d that abuts around the periphery of the ignition. The electrode 9 was prevented from rotating.

[0009] Further, in the embodiment shown in FIGS. 7 and 8, the screw tube 17 of the ignition electrode 9 is connected to the inner tube 1a. The inner cylinder is provided to penetrate the bottom plate of the outer cylinder 1b, and serves as the rotation means 14 of the screw cylinder 17. The hexagonal flange 17a at the upper end of the screw tube 17 is formed by embossing on the bottom plate of the screw tube 17. Two convex portions 20 are provided at the locations that contact the outer periphery, and the convex portions 20, 20 are provided with the convex portions 20, 20. By abutting the outer periphery of the upper end flange 17a, the ignition electrode 9 is connected to the inner and outer cylinders 1a and 1b. This prevents it from rotating when heated.

0010 Incidentally, the electrical component is not limited to the ignition electrode 9, but also the frame shown in FIG. Needless to say, the rod 19 may be used, and the rotation means 14 may also be the same as in the above embodiment. It is not limited.

[0011] Furthermore, I explained about a liquid combustor that vaporizes and burns kerosene. , This is an example of a method used in the 1970s, in which fuel is injected into a pot burner from a nozzle to burn it. It can also be applied to the so-called gun pot type liquid combustor known from Publication No. 0-27432. Needless to say.

0012

[Effect of the idea]

The liquid combustor having the above configuration has the following effects. Even if the electrical parts loosen when the inner cylinder and outer cylinder are heated, the locking means will prevent can prevent electrical components from rotating, and prevent malfunctions caused by rotating electrical components. For example, when the electrical component is an ignition electrode, the ignition electrode is too far away from the ground electrode or If they are too close together, a spark cannot form between them and the ground electrode, and the electrical components may cause flames. In the case of a flame rod to be monitored, the flame rod may come in contact with the ground side and Problems such as the inability to detect flow can be resolved.
