Abstract

PURPOSE:To shorten the flame quenching time when the titled apparatus turned over, by providing a porous member at an opening as well as to divide a flame chamber into a plurality of chambers, in a combustor to which outer side of a wick guide cylinder a ring-form chamber is provided and the chamber is communicated to the open air by the intermediary of an opening which is opened when the wick is descended. CONSTITUTION:The titled apparatus is composed in such a manner that a cylindrical wick 4 is provided in a vertically movable manner between cylindrical inner and outer guide cylinders 2 and 3 which are provided in upright passing through the center part of a fuel tank 1. A ring-formed opening 5, which is opened when the wick 4 is descended at the time when flames are extinguished, is provided to the upper part of the outer guide cylinder 3, and a ring-formed chamber 6 is provided in the outer side of a guide cylinder 3 which is in an opposite side of the wick 4 on the side of an opening 5. In this case, a plurality of plate bodies 7 are provided to the ring-formed chamber 6 to divide the chamber 6 into a plurality of chambers, having gaps in the circumferential direction, at the same time, a ring-formed porous member 15 made by wire sheet is provided between the plate body 7 and the opening 5, having a predetermined interval. In addition, an air inlet port 8 is provided to each divided chamber 6.

Description

[Detailed description of the invention] The present invention relates to liquid fuel combustors. .

A conventional example is shown in FIG.

In this conventional lamp, cylindrical guide tubes A and B are provided, and a cylindrical lamp wick C is provided between the guide tubes A and B so as to be movable downward.

The wick C is shown in the dashed line in the guide, and there is an opening that is closed by the wick C when the wick C goes up and burns, and is opened when the wick C goes down to extinguish the fire, as shown by the solid line. In one or more configurations, a ring-shaped chamber E is provided on the outside of this opening, and a hole F is provided around the entire circumference of this chamber E through which air flows in during extinguishing. is raised one step as shown by the broken line, and combustion is performed in combustion tubes (not shown) placed on the fire pans G and H. When extinguishing a fire, lower the wick C between guide tubes A and 3 as shown by the solid line to extinguish the fire.

When extinguishing this fire, the vaporized gas from the wick C and the hole F in the room E.
The air from the fire mixes and explodes instantly, and this blast forms near the fire 1111G and H, blowing out the flame 2, thereby shortening the extinguishing time.

However, this had the following fc1 problem.

In other words, in the event of a fall, the vaporized gas in room E will collect on the lower side of room E, and the remaining flame that was not completely extinguished by the explosion will propagate and burn slowly, which means that it will take a long time to extinguish the fire. Therefore, the present invention divides the chamber into a plurality of parts in the circumferential direction, and also provides a porous section between the plate and the opening 11.
This is an attempt to eliminate the above-mentioned conventional problems.

An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 3, 1 is a fuel tank, and a cylindrical guide tube 2 is erected through the center of the tank 1.

′-! Cylindrical guide tubes 3 are provided on the outer periphery of the octopus guide tube 2 at predetermined intervals, and a cylindrical lamp wick 4 is provided vertically movably between these guides. There is.

In addition, a link-shaped J6 is provided at the upper part of the guide tube 3, and this opening 1-15 is closed by the wick 4 when the wick 4 is raised as shown by the broken line and burned. When extinguishing a fire, the wick 4 is the guide tube 2 (as shown by the solid line)
, 3, the opening is lowered below the opening 6, so that it is opened.

Further, a ring-shaped chamber 6 is provided on the outside of the opening 6 on the opposite side of the phantom core 4, and within this chamber 6, as shown in FIG. It is set up to be divided into. A ring-shaped porous member 16 made of wire mesh is provided between the plate member 7 and the opening 5 at a predetermined distance from the opening 16. Further, each divided chamber 6 is provided with a hole 8 through which air flows.

Note that 9 is the inner flame cylinder 10. Outer flame cylinder 11. The outer cylinder 12.1 is a combustion cylinder.

In the above configuration, when combustion is to be performed, the lamp wick 4 is moved +H so that it enters the space between the inner and outer flame tubes 10 and 11 as shown by the broken line, and is thereby ignited to cause combustion.

To extinguish the fire, the wick 4 is lowered from the opening 1]6 between the guide tubes 2 and 3 as shown by the solid line, thereby extinguishing the fire.

In this case, the vaporized gas from the wick (4 or C) and the air flowing in from the hole 8 mix in the chamber 6 and explode instantly, and the blast blows out the flame near the fire pan 13, 1454, instantly extinguishing the fire. [7] to be able to do it.

Now, even in the event of an earthquake or other such event, the wick 4 should be lowered before it falls, as shown in Figure 2, and #'l, i'f! It is performed by only one person.

Figure 3 shows the state after the wick falls. Air flows into the chamber 6 from the hole 8a below the tipped 1 as shown by arrow A due to the draft effect, and the vaporized gas from the broken wick 4 weighs as shown by arrow B. As a result, water flows in the direction of arrow B, and this mixes.

In this case, since the chamber 6 is divided into a plurality of parts by the plate 7, the mixed gas does not circulate within the chamber 6. Therefore, even if a flame remains for some reason and the flame ignites, it will not ignite the plate. The ember burns between the body 7a and the plate body 7a, and the extinguishing time becomes long. Porous part 16 prevents ignition from entering the outer chamber 6.
This also prevents the extinguishing time from increasing. Note that this is the same even if the holes 8 are not provided, but the holes 8 are more advantageous in that the gas mixture between the plates 7a and Tb is combusted as quickly as possible.
