Abstract

PURPOSE:To obtain a durable wick excellent in the fire accelerating and extinguishing property against tumbling by fitting a combustion core made up of a ceramic fiber with a fire accelerating wick and a reinforcing body. CONSTITUTION:A combustion wick section 2 which is sewn on a sucking cylindrical wick section 1 made of a cotton cloth treated for repelling water butting the upper end thereof is a cylindrical ceramic fiber wick made up of a ceramic fiber less than 4mum thick solidified with a binder. A cylindrical fire accelerating wick 3 made of a glass fiber cloth is mounted outside the wick section 2. A cylindrical reinforcing body 4 made up of a glass fiber cloth is mounted on the inner surface thereof opposite the fire accelerating wick 3. This reinforcing body 4 is sewn A on the upper end of the sucking wick section 1 at the lower end thereof together with the fire accelerating wick 3 and the combustion wick section 2 while on the fire accelerating wick 3, a combustion wick 3 and the combustion wick section 2 to make an integral assembly. This improves the durability of the wick assembly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wick for an oil combustor using ceramic fibers.

Generally, a wick for an oil combustor is constructed by connecting a combustion wick made of glass fiber to a fuel suction wick made of cotton or the like.
The above-mentioned combustion core made of glass fiber has a low oil content, and when inferior kerosene is used, tar is generated and accumulated, resulting in a reduction in the amount of combustion in a short period of time.

As a solution to these problems, ceramic fibers made into paper and hardened with a binder have recently come into use. This ceramic fiber core has the advantage of having a high oil content, so even if inferior kerosene is used, the combustion rate will not decrease in a short period of time. However, the problem with this ceramic fiber wick is that it is easily broken when the wick is moved up and down.

The present invention solves the above problems, and one embodiment thereof will be described below with reference to the drawings.

In the figure, 1 is a cylindrical wicking core made of water-repellent cotton cloth, 2 is a combustion wick that is sewn against the upper end of the wicking core 1, and is made of ceramic fibers of 4μ or less, hardened with a binder. A cylindrical ceramic fiber core is used, and a cylindrical fire core 3 made of glass fiber cloth is attached to the outer surface of the core. Furthermore, a cylindrical reinforcing body 4 made of glass fiber cloth is attached to the inner surface on the opposite side from the fire wick 3. This reinforcing body 4 is the fire core 3,
Together with the combustion wick 2, its lower end is sewn to the upper end of the suction wick 1, and its upper end is sewn to the fire wick 3 and the combustion wick 2 to be integrated.

The combustion wick part 2 made of the above-mentioned ceramic fiber wick is covered by a fire wick 3 and a reinforcing body 4, and the tensile force (frictional resistance generated between the wick guide tube walls 6, 6) that is applied when the wick goes up and down. [Normal 1 ok/cm)] If it is applied directly to the combustion wick 2, it will explode, causing the wick 3 and the reinforcing body 4 to change shape, and there is a risk of breakage even after long-term use. disappears. In addition, since the oil content of the fire-spinning wick 3 provided on the surface of the combustion wick 2 is not so high, even if the combustion wick 2 contains a large amount of oil, good fire-spinning can be carried out, and the reinforcing body 4 absorbs the oil that flows out between the wick guide tube and the lamp wick when the combustor falls over (the combustion wick 2 contains oil near the saturated state, so it cannot absorb the oil that flows out) This has the advantage of eliminating problems such as prolonged extinguishing time when oil spills occur when equipment falls over.

FIG. 3 shows another embodiment of the invention, in which the lower part of the reinforcing body 4 extends below the seam.

As is clear from the above description of the embodiments, according to the present invention, a lamp wick made of ceramic fiber can be obtained which has good durability and good fire-spinning and fall-extinguishing properties.
