The present invention relates to a wick heat insulation device of a wick lift type oil combustor, which prevents hot heating during the ignition of the combustor, thereby making it possible to have a faster time during an emergency fire extinguishing operation due to the conduction of the combustor. It is to be digested quickly within.

Usually, the wick lift type oil combustor raises the wick so that the wick can be urgently automatically lowered and extinguished by the rapid operation of the anti-vibration device installed separately in the combustor of the combustor. At this time, the use of safety that must be completely extinguished the flame attached to the wick within about 10 seconds was required. This is because the fire inside the combustor's city fuel tank must be completely extinguished before the fuel flows out.

However, the conventional wick lift type oil burner has heated the wick during the ignition combustion, and gas is generated inside the fuel tank, and the gas inside the tank is discharged to the outside by a separate gas discharge device to the upper part of the wick. Even if the backfire phenomenon was removed to prevent gas backflow, the wick and especially the wick were heated so that the time remaining until the flame remaining in the wick was completely extinguished. .

The present invention solves the conventional problems as described above, so that the heat conduction (염 道 차) by the flame to prevent the wick from heating during ignition combustion, within 10 seconds during the emergency fire operation by the combustion of the combustor The purpose is to increase the safety by quickly extinguishing the fire completely, and will be described in detail based on the accompanying drawings. That is, a plurality of downward projections (2) and the air distribution hole (3) to the lower end of the outer bending ring (1) by arranging cross-arranged to the lower bending piece (1a) at regular intervals on the upper surface of the wick outer cylinder (4) (2) is fixed so as to form a gap (S), and the inclined inner cylinder (6) of the oil combustor by installing the inclined heat shield plate (5) so as to extend from the outer peripheral edge of the upper end of the outer cylinder shield ring (1) to the outside Wick lift type oil combustor characterized in that the inner cylinder shielding cap (7) having a plurality of support pieces (7a) is bent inwardly at the upper end and fixedly installed by the support pieces (7a) locally It is a wick heat shield device.

In the accompanying drawings, reference numeral 8 denotes a support piece for installing the inclined heat shielding plate 5, 9 denotes a gas discharge pipe, 10 denotes a damper, 11 denotes a fuel tank, and 12 denotes a wick.

In the present invention, as shown in FIG. 1, the heat generated by the flame when the wick 12 is raised and burned is conducted to the wick outer tube 4 and the wick inner tube 6, wherein the wick is wicked. Since the outer cylinder shielding ring 1 is fixed to the upper end of the outer cylinder 4 at intervals S, the thermal conductivity transmitted from the outer cylinder shielding ring 1 that is heated by heat to the wick outer cylinder 4 is a projection ( 2) It is limited to only the part, and at the same time, the heat of the outer cylinder heat shield ring 1 is diverted to the outside through the inclined heat shield plate 5, thereby preventing the wick outer cylinder 4 from being heated.

On the other hand, the inner cylinder shield cap (7) is locally fixed to the upper end portion of the wick inner cylinder (6) by a plurality of downward support pieces (7a) to be heated by the conductivity by the flame (7) As the heat conduction from the wick 6 to the support piece 7a is limited to only the portion, the conductivity is greatly reduced to prevent the wick 6 from being heated.

Accordingly, the wick 12 is prevented from being heated up to the wick outer cylinder 4 as well as the wick inner cylinder 6 by the anti-vibration apparatus which is operated quickly when the combustor is inverted due to carelessness or mistake during ignition combustion of the combustor. In case of urgent extinguishing operation rapidly descending, the internal temperature of the wick outer cylinder 4 and the wick inner cylinder 6 surrounding the inner and outer sides of the wick 12 is low, so that the final extinguishing action of the flame remaining in the lowered wick 12 is performed. It will be done quickly. This is a very useful design that has been confirmed that the time required for a complete fire extinguishing is not more than 10 seconds as a result of several tests, so that the risk of a fire, etc. can be eliminated in case of an emergency such as the conduction of a combustor.
