Embodiment Construction

[0009] The sandblasting fire extinguishing device provided by the present invention uses compressed air as power to spray the stored sand to the scene of a fire, so as to cover the hazardous chemicals on fire and isolate them from the air to achieve the purpose of extinguishing fire. At the same time, it can also prevent the flow of combustion liquid ( Flowing fire) spread.

[0010] The following describes the sandblasting fire extinguishing device in detail. The sandblasting fire extinguishing device is used to connect with an external compressed air supply device. The compressed air flow provided by the external compressed air supply device is used to spray out the stored fire extinguishing sand and extinguish the fire. Please also refer to figure 1 , The sandblasting fire extinguishing device 10 includes a compressed air diversion device 30, a sand storage device 40, and a sandblasting device 50.

[0011] The compressed air diversion device 30 is connected to the sand storage de...

Abstract

A sandblast fire-extinguishing device comprises a compressed air supply device, a compressed air flow dividing device, a sand storage device and a sandblast device, wherein the compressed air flow dividing device is connected with the sand storage device and the sandblast device; the sand storage device is further connected with the sandblast device; the compressed air flow dividing device is used for dividing compressed air flow provided by the compressed air supply device into first compressed air flow with a first pressure value and second compressed air flow with a second pressure value, conveying the first compressed air flow to the sand storage device and conveying the second compressed air flow to the sandblast device; the sand storage device is used for storing fire-extinguishing sand and conveying the stored fire-extinguishing sand to the sandblast device at a first speed under the action of the first compressed air flow; the sandblast device is used for increasing the speed of the fire-extinguishing sand with the first speed value by using the second compressed air flow so as to enable the fire-extinguishing sand entering the sandblast device to spray out from the sandblast device at a second speed value.

Description

Technical field [0001] The invention relates to a fire extinguishing device, in particular to a sandblasting fire extinguishing device. Background technique [0002] When a hazardous chemical fire occurs, the best, most direct and effective way is to cover the fire with sand. However, the current use of sand to extinguish fires is still manual operation with a shovel, which is low in efficiency and dangerous and cannot be operated remotely. Missed the best time to save. Summary of the invention [0003] In view of this, it is necessary to provide a sandblasting fire extinguishing device that can quickly cover the fire surface with sand to achieve fire extinguishing. [0004] A sandblasting fire extinguishing device includes a compressed air supply device, a compressed air diversion device, a sand storage device, and a sandblasting device. The compressed air supply device is connected with the compressed air diversion device, and the compressed air diversion device is connected with...
