Problems solved by technology

[0003] But no matter it is a traditional dry powder fire extinguishing device or an existing dry powder fire extinguishing device connected with a gas tank of high-pressure gas, when it is stored, the tank body of inert gas and the gas tank of high-pressure gas are stored at a relatively high temperature. It is easy to explode when it is high or hit, so these two dry powder fire extinguishing devices have caused a greater safety hazard in the storage process.

Embodiment 1

[0037] figure 1 It is a cross-sectional view of the dry powder fire extinguishing device provided by Embodiment 1 of the present invention, see figure 1 As shown, the dry powder fire extinguishing device provided by the present invention includes: a tank body 1 and a fixing seat 2 sealingly connected with the tank body 1; the fixing seat 2 is also provided with a combustion chamber 3 communicating with the inside of the tank body 1 The combustion chamber 3 is also connected with an ignition device 4; the combustion chamber 3 is provided with a combustion charge 5.

[0038] In this embodiment one, since the fixed seat 2 is provided on the tank body, the combustion chamber 3 communicated with the interior of the tank body 1 is provided on the fixed seat 2, so when the ignition device 4 is ignited, and the combustion chamber 3 is placed When the burning powder 5 is ignited, the burning powder 4 burns to produce a large amount of gas rapidly, and the combustion chamber 3 communic...

Embodiment 2

[0040] figure 2 It is a schematic structural view of the combustion chamber 3 in the dry powder fire extinguishing device provided by Embodiment 2 of the present invention, see figure 2 As shown, on the basis of the first embodiment above, the combustion chamber 3 is also provided with a solid medicine spring 6 and a medicine retaining plate 7 for fixing the combustion grain 5; The medicine plates 7 are respectively arranged at both ends of the combustion chamber 3; the burning medicine column 5 is arranged between the solid medicine spring 6 and the medicine blocking plate 7 and abuts against both.

[0041] In the second embodiment, the two ends of the combustion chamber 3 are respectively provided with a solid medicine spring 6 and a medicine retaining plate 7, and the solid medicine spring is elastic, so that the combustion powder column 5 can be fixed on the solid medicine spring 6 and the medicine retaining plate 7, it is ensured that no matter in the process of transp...

Embodiment 3

[0043] see image 3 As shown, the dry powder fire extinguishing device provided by the present invention is based on the above two embodiments, and the tank body 1 is also provided with a dry powder outlet 8 .

[0044] In the third embodiment, the ignition device 5 ignites the combustion powder column 5, and after a large amount of gas is generated, the air pressure in the tank body 1 is higher than the atmospheric pressure, so the dry powder stored in the tank body 1 is discharged from the dry powder outlet 8 Squeeze it out. The dry powder is extruded and ejected from the dry powder outlet 8, so as to reach the fire site and achieve the purpose of extinguishing the fire.

[0045]In the present invention, the dry powder fire extinguishing device can be set to be movable, or the dry powder fire extinguishing device can be set to be fixed. When the dry powder fire extinguishing device was fixed, the powder delivery pipeline 9 was also connected to the dry powder outlet 8 . Du...

Abstract

The invention relates to the field of fire safety equipment, and in particular relates to a dry powder extinguisher. The dry powder extinguisher comprises a tank body and a fixed seat which is connected with the tank body in a sealing manner, wherein a combustion chamber which is communicated with the inner part of the tank body is further arranged on the fixed base; an ignition device is further connected with the combustion chamber; and a combustion powder column is arranged in the combustion chamber. The combustion chamber which is communicated with the inner part of the tank body is arranged on the fixed base, so the combustion powder column in the combustion chamber is ignited by the ignition device, and a lot of gasses are quickly generated through the combustion of the combustion powder column; the communication chamber is communicated with the inner part of the tank body, so the generated gases enter the inner part of the tank body from the combustion chamber. The size of the inside of the tank body is limited, so when the gas pressure in the tank body is higher than the atmospheric pressure, the dry powder stored in the tank body is pressed out from the tank body to reach the fire breakout position, thereby achieving the purpose of extinguishing. Thus, the dry powder extinguisher provided by the invention does not need to be stored under high pressure as the dry powder extinguisher in the prior art.

Description

technical field [0001] The invention relates to the field of fire safety equipment, in particular to a dry powder fire extinguishing device. Background technique [0002] Traditional dry powder fire extinguishing devices generally include a tank body containing dry powder, and a nozzle connected to the tank body. Inert gas is also stored in the tank body, so that the pressure inside the tank body is greater than atmospheric pressure. When the fire needs to be extinguished, the nozzle is turned on. Since the pressure in the tank is higher than the atmospheric pressure, the dry powder is ejected from the nozzle under the pressure of the inert gas and reaches the fire location, thereby achieving the purpose of extinguishing the fire. In this traditional dry powder fire extinguishing device, the higher the air pressure in the tank, the greater the amount and speed of the dry powder sprayed out, and the better the fire extinguishing performance. However, the greater the pressur...
