In addition, a fluorescent substance or a dye may be included, and examples of the fluorescent substance include zinc silicate, cadmium silicate, and haloin calcium. Propellant may be made by mixing the extinguishing agent and fluorescent material. Dye or fluorescent material is mixed with the propellant to produce a visually detectable effect when spraying. The dye may be used as a natural dye synthetic dye. The dye may be included in the solid powder state.

Extinguishing agents include acid alkali extinguishing agents containing sodium hydroxide (2NaHCO ₃ ) and sulfuric acid (+ H ₂ SO ₄ ), extinguishing agents containing potassium carbonate (K ₂ CO ₃ ) and sulfuric acid (+ H ₂ SO ₄ ), Extinguishing agents in which sodium carbonate (6NaHCO ₄ ) and aluminum sulfate (Al ₂ (SO ₄ ) ₃ 18H ₂ O) are mixed, and extinguishing agents such as halon 1301, halon 1211, halon 2402, and halon 104 may be used.

Conveyor roller 100 having a spraying function according to the present invention may further include a pressure accumulating member 113 to expand in accordance with the temperature rise in the hollow portion of the shaft as shown in FIG. When the propellant is provided in the space S formed between the roller body and the shaft 105 as shown in FIG. 5, although not illustrated, the accumulator member is disposed in the space S formed between the roller body and the shaft 105. It is provided.

The accumulator member is provided at a position that is operated to press the propellant into the discharge hole while expanding. When the blocking member 111 is formed in a bag shape and the injection medicine is accommodated in the blocking member 111, the accumulating member 113 may be provided to be positioned opposite to the discharge hole. The blocking member 111 is located between the accumulator member 113 and the discharge hole.

The accumulator member 113 includes a support member 1131 that is open toward the discharge hole and a movable member 1133 slidably provided in the support member 1131 in the axial direction. In FIG. 3, reference numeral 1137 illustrates a seal member provided between the inner diameter surface of the support member 1131 and the inner diameter surface of the

movable member

1133, and 1135 denotes the support member 1131 on the opposite side of the movable member 1133. It shows a fastening screw fastened to the screw. Expansion gas is filled in the space formed between the support member 1131 and the movable member 1133. The filling gas may be nitrogen gas.

When the conveyor roller 100 having the spraying function according to the present invention is mounted and rotated, it is not rotated due to the damage of the bearing 107, so that frictional heat is generated between the conveyor belt and a fire is generated by the frictional heat. When the temperature of the accommodating part containing the injection drug is increased, the volume increases with temperature rise, and the blocking member 111 is expanded. In the case where the accumulator member 113 is provided, the expansion gas filled in the space formed between the support member 1131 and the movable member 1133 is also expanded so that the movable member 1133 is slid toward the end of the support member 1131. Pressurize the propellant

When the blocking member 111 is ruptured by the expansion, the injection chemical is discharged through the discharge hole. When the reflective member 128 is provided, the jetted drug discharged through the discharge hole collides with the reflective member 128 and the movement direction is changed to move inward in the axial direction. When the nozzle member 127 is provided, guided through the nozzle member 127 is discharged to the outside, leaked from the end of the second extension portion (127b) and sprinkled upward of the conveyor roller 100 having an injection function You lose. When the second extension part 127b is provided in a plurality of branches or is provided with a plurality of nozzle members 127, the second extension part 127b is discharged in multiple directions.

When the blocking member 111 is formed of a release valve, the release valve is opened by the pressure rise and discharged to the outside.

If the propellant is made of extinguishing agent, the extinguishing agent is sprayed at the initial stage of the fire, and extinguishing is performed, and if the fluorescent substance or dye is contained, it is visually identified. When the needle member 124 is provided, the blocking member 111 that swells and ruptures in contact with the needle member 124. On the other hand, when the whistle means generated in the discharge hole or the nozzle member 127 is provided, there is an effect that can alarm the fire by sound.
