Problems solved by technology

[0003] There are at least the following two deficiencies in the existing dry powder fire extinguishing device: the one is that the sealing of the lead wire package is not good enough, and the pressure will be released from the lead wire hole when the drug block explodes, so that there is not enough gas pressure to spray t

Embodiment Construction

[0026] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0027] attached figure 1 The best embodiment of the present invention is shown, which is a dry powder fire extinguishing device, which includes a packaging cylinder 1 filled with dry powder fire extinguishing agent, a packaging cover plate 2, an explosive device 3 and a spraying device 5.

[0028] The upper end of the packaging cylinder 1 is open, and is firmly sealed with the packaging cover plate 2. The firm sealing method can adopt a press-fit sealing structure, that is, the surrounding edges of the packaging cover plate 2 are bent inward to form a sealing curl. Pack and wrap the upper end opening of the packaging cylinder 1. The explosive device 3 is placed in the packaging cylinder 1 and mounted on the lower surface of the packaging c...

Abstract

The invention discloses a dry powder fire-extinguishing device. The dry powder fire-extinguishing device comprises a packaging cylinder, a packaging cover plate, an explosion device and an injection device; the explosion device is mounted on the lower surface of the packaging cover plate; a sealing device is arranged between the packaging cover plate and the explosion device; the sealing device atleast comprises one flexible layer and one heat-insulating layer; the explosion device comprises a heat-sensitive lead; a first lead hole for the heat-sensitive lead passing through is formed in theflexible layer, and a second lead hole for the heat-sensitive lead passing through is formed in the heat-insulating layer; and the projection of the first lead hole and the second lead hole on a planeof the packaging cover plate does not overlap after the dry powder fire-extinguishing device is assembled. The dry powder fire-extinguishing device has good air-tightness, sufficient pressure in thepackaging cylinder is effectively ensured, and a dry powder fire-extinguishing agent is more efficiently sprayed.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing devices, in particular to a dry powder fire extinguishing device. Background technique [0002] The dry powder fire extinguishing device is to extinguish the fire by spraying dry powder. The principle of dry powder fire extinguishing is: one is to rely on the volatile decomposition products of inorganic salts in the dry powder to chemically inhibit and interact with the free radicals or active groups produced by the fuel during the combustion process. The negative catalytic effect interrupts the chain reaction of combustion and extinguishes the fire. The second is to rely on the powder of the dry powder to fall outside the surface of the combustibles, undergo a chemical reaction, and form a glassy covering layer under the action of high temperature, thereby isolating oxygen and suffocating the fire. It is suitable for fully enclosed spaces, semi-enclosed spaces or outdoors. Open space ...
