Knapsack dry powder fire extinguishing gun

Abstract

The invention discloses a knapsack dry powder fire extinguishing gun, and belongs to the technical field of fire fighting equipment. The main points of the technical scheme are that the knapsack dry powder fire extinguishing gun comprises a dry powder tank, a knapsack component, a gas tank, a spray gun and a main gun frame; the dry powder tank, the gas tank and the spray gun are connected by a pipeline and used cooperatively; the knapsack component is installed on the front of the dry powder tank; the gas tank and the main gun frame are installed on the left and right sides of the dry powder tank respectively; the spray gun comprises a handle and a barrel that are combined together that can be placed on the main gun frame, and are used cooperatively; a first steel ring and a second steel ring are hooped outside the barrel of the spray gun; the second steel ring is close to a launch port of the barrel of the spray gun; and the first steel ring is positioned between the second steel ringand the handle of the spray gun. The knapsack dry powder fire extinguishing gun can quickly and accurately place the spray gun on the gun frame, reduces the requirement for proficiency in use, and can conveniently and quickly clear up residual dry powder on a muzzle of the spray gun and the outer wall of the barrel.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a backpack type dry powder fire extinguisher. Background technique [0002] The knapsack dry powder fire extinguisher can extinguish general fires, and can also extinguish fires caused by fuel combustion such as fuel oil and gas. The knapsack dry powder fire extinguishing gun uses high-pressure carbon dioxide gas or nitrogen gas as power to spray the dry powder in the barrel to extinguish the fire. Dry powder is a kind of dry, easy-flowing fine solid powder, which is composed of base material capable of extinguishing fire and additives such as moisture-proof agent, flow promoter, caking preventive agent and so on. It is mainly used to extinguish the initial fires of flammable liquids such as oil and organic solvents, combustible gases and electrical equipment. [0003] With the development of the fire-fighting equipment manufacturing industry, knapsack dry powde...

Problems solved by technology

[0004] 1. After wearing the traditional knapsack-type dry powder fire extinguisher, it is difficult for the operator to quickly and accurately align the spray gun and place it on the gun rack. It often requires long-term practice and requires high proficiency in use

[0005] 2. After the spray gun used to spray dry powder is used, a lot of dry powder will inevitably remain on the muzzle and the outer wall of the barrel. If the spray gun with dry powder is placed on the gun holder without cleaning, it will Dirty or even clogging the gun frame, it is difficult to clean up later. After a long time, the dry powder will deteriorate and solidify, which will further increase the difficulty of cleaning, and seriously cause the gun frame and barrel to be scrapped. The traditional method is often to manually wipe the spray gun first. It is very troublesome to place it on the gun rack, and the fire scene is complicated. It is likely that there is no time or no tools for this step.
