Abstract

The invention relates to fire extinguishing agents, can be used in devices for powder extinguishing of solid and liquid combustible materials and allows to increase the reliability of the device operation by preliminarily loosening the packed fire extinguishing powder. In the spherical powder container I, a drive sickle-shaped knife 8 with side cutting edge and radial knives 10 is installed, the drive of the sickle-shaped knife is made in the form of a rotary-blade rotary air motor II integrated into the high-pressure gas main in such a way that the output outlet of the air motor communicates with the cavity 6 formed by the inner surface of the container and the elastic sheath, and with the outlet pipe. The crescent knife provides preliminary loosening of the powder with the subsequent supply of compressed air into the cavity of the elastic sheath to push the powder and into the outlet. 3 silt; (L to I lAd 4 vj; D i (yi

Description

The invention relates to fire safety measures, in particular to devices for powder extinguishing.

The aim of the invention is to increase the reliability of the device by preliminarily loosening the packed powder.

FIG. 1 schematically depicts a device in FIG. 2 is a cross section of LL in FIG. ; in fig. 3 section bb on} jHT. one .

Instruments D) to extinguish the knife with a dorzhi spherical container filled with powder; -, 1 with plastic sheath 2 cracked inside it to allow: removal of the powder. The reservoir 1 comes in 1.1,:; single and double wall pipe 3,} 511 internal wall 4 of which is filled with a perforated cone in the form of an adapter - an irisive nozzle. The device has a high-pressure gas line 5 connected to a cavity 6 formed by the inner {{its surface of the tank 1 and the elastic sheath 2, the outlet double-wall pipe 3 and the high-pressure gas source 7). Inside the tank 1 there is a drive sickle - shaped knife 8 with a side cutting edge 9 and radial knives 10 attached to it.

The drive of the crescent-shaped knife 8 is made in the form of a rotary blade rotary motor 11, built into the high-pressure gas main 5 in such a way that the output pneu-motor 1 pneumatic stroke rod 1 1 is connected to the mainline from the sides, cavity 6 and the output double-walled branch pipe 3.

The pneumatic engine has a rotary vane 13 and the inlet fitting 14.

In the high-pressure line with honey, a pneumatic motor and a source of high-pressure gas are installed with a diaphragm unit 15.

The device works as follows.

When the device is turned on, the diaphragm of the block 15 breaks through and the sG gas from the source 7 enters the pneumatic actuator 11 through the inlet strude 14, I act on the rotary blade 13 to compress The gas ensures the rotation of the pneumatic motor blade together with the sickle-shaped knife 8, as a result

the powder is loosened. In the extreme position, the rotatable blade communicates the outlet nipple 12 with the inlet nipple 4, whereby the compressed gas is fed through line 5 into the cavity 6, and the elastic casing 2 provides for ejecting the powder through the outlet 3. At the same time, the compressed gas also flows into the outlet nipple 3 spray powder.

Thus, the compacted powder is preliminarily loosened and, by the time the compressed gas is supplied to the cavity of the elastic shell, it is better prepared to be released through the outlet 3. This effect improves the reliability of the ejection of the extinguishing powder after prolonged storage, which is the technical and economic advantages of the proposed , constructions.
