Abstract
The invention discloses a handheld air-foam fire extinguisher; a foaming tube (10) consists of a circular tube (28), a bracket and a circular tube fixing hoop (24), one end of the bracket is fixed on the circular tube (28) and the other end thereof is fixed on the circular tube fixing hoop (24); the circular tube fixing hoop (24) adopts a pin roll for rotatable connection of the circular tube through a pin roll seat fixed on the side wall of a foam fire extinguishing agent barrel (13); the foam fire extinguishing agent barrel (13) is fixed at the exterior of an imbibing chamber (7) by a bolt and a nut, as the invention uses the straight type circular tube as the foaming tube, when the dispersing high speed foam flow sprayed from a nozzle hits the inner wall of the foaming tube, large amount of energy consumption does not appear, thus causing no impact on the speed of the high speed foam flow sprayed from the nozzle of the foaming tube, ensuring longer distance of the air foam spray compared with the prior air-foam fire extinguisher, reducing staff injury and death or property loss, and at the same time, the handheld air-foam fire extinguisher can be more conveniently carried and used by one person.
Description
Technical field
The present invention relates to a kind of air-foam fire extinguisher, is a kind of improvement of portable air foam fire extinguisher structure specifically.
Background technology
For one of method that occurs in tunnel, colliery, airport, oil cellar, garage, boats and ships, warship and put out a fire to save life and property at the fire that causes by water-insoluble inflammable, flammable wandering liquid of the confined space, be to adopt air-foam fire extinguisher.So-called air-foam fire extinguisher; Mix mutually with water and air by fire foam exactly; Produce foam; Cover the surface of water-insoluble inflammable, flammable, the liquid that can scatter of burning, make it and contain the air insulated of oxygen that can be combustion-supporting, thereby make water-insoluble burning inflammable, flammable, the liquid that can scatter be able to extinguish.Said fire foam, having a kind of is that hydrolysis concentrate with animal protein is a base-material, an amount of additives such as stabilizing agent, anticorrisive agent and antifreezing agent are processed in addition.The one Chinese patent application of being submitted in 2008 by applicant 200810140306.1 discloses a kind of air-foam fire extinguisher, and said air-foam fire extinguisher is a kind of backpack fire extinguisher, comprises that the pipe tooth connects button, the fire foam bucket; Imbibition joint and sebific duct, said imbibition joint has valve, and said imbibition joint links through sebific duct and fire foam bucket, and it comprises that also double end is external; The fluid by-pass valve control, double end connects silk, collector; The imbibition chamber disperses baffle plate, copper sheathing; Nozzle and foaming tube are packed said fire foam in the backpack extinguishing chemical bucket into, and the extinguishing chemical bucket links through the imbibition joint of sebific duct and air-foam fire extinguisher.During use, on user's shoulder, the pipe tooth that fire extinguisher canvas hose is connected on air-foam fire extinguisher connects to be buckled with the extinguishing chemical bucket back of the body, and a subtend ignition zone will foam; Open fire extinguisher canvas hose, will go out hydraulic control valve and open gradually, the water of High Voltage will connect through the pipe tooth and tip in into collector, sucks fire foam from the imbibition joint; Disperse baffle plate through frustum, get into nozzle, form powerful pressure; Mix the foam that the back forms with inhaled air, diffusion atomizing immediately is again through foaming tube tube head; Form powerful negative pressure once more, suck a large amount of air, so that form the high speed foam stream; Be sprayed in the foaming tube cylinder, pass through the bump with silk screen again, further form more foam; Spray and cover the surface of water-insoluble inflammable, flammable, the liquid that can scatter of burning, make it and contain the air insulated of oxygen that can be combustion-supporting, thereby make burning be able to extinguish.But; In use there are several problems in said foam annihilator: 1, must froth liquid vessel be connected use with said foam annihilator; The necessary portable foam annihilator of fire fighter; The portable froth liquid vessel of another is perhaps carried and is operated by two fire fighters, makes troubles for on-the-spot fire extinguishing; 2, because said air-foam fire extinguisher support one end is fixed in cylinder, and the other end is fixed in a head, makes whole air-foam fire extinguisher seem long, carrying and use are not very convenient in the scene of fire; 3, because said foaming tube is the big cylinder of mid diameter, the air stream of ejection can consume part energy when being ejected into the different cylinder side wall of diameter, lowered the speed of foam stream injection, makes the jet length of foam be affected.
Before technical scheme of the present invention is accomplished; Not seeing the portable air foam fire extinguisher identical with structure of the present invention uses in daily life; Not seeing the portable air foam fire extinguisher identical with structure of the present invention has sale on market, it is on the books in document also not see the portable air foam fire extinguisher identical with structure of the present invention.
Summary of the invention
The object of the present invention is to provide a kind of portable air foam fire extinguisher; In use can make the air that produces spray than existing air-foam fire extinguisher and spray farther distance; Reduce casualties or property loss; Minimizing is to fire fighter's injury, carries simultaneously and uses convenient.
For realizing the foregoing invention purpose, the present invention adopts following technical proposals:
