Abstract

The utility model discloses a hand-held air foam fire extinguisher. A foaming drum (10) consists of a drum (28), a bracket and a drum fixing hoop (24); one end of the bracket is fixed on the drum (28), and the other end thereof is fixed on the drum fixing hoop (24); the drum fixing hoop (24) is fixed on the hinge pin seat on the side wall of a foam fire extinguishing foam barrel (13); the drum is in ratable connection through a hinge pin; and the foam fire extinguishing agent barrel (13) is tightly fixed outside a liquid absorption chamber (7) through bolts and nuts. As the hand-held air foam fire extinguisher adopts a straight type drum as the foaming drum, when the divergent high-speed foam flow sprayed out of a nozzle strikes onto the inner wall of the foaming drum, high energy consumption is not caused, therefore, the speed of the high-speed foam flow sprayed from the foaming drum mouth is not influenced; when in use, the hand-held air foam fire extinguisher leads the spray distance of generated air foam to be farther compared with the existing air foam fire extinguisher, thus reducing personal injury or property loss, and simultaneously being conveniently carried and used by one person, and leading the carrying and using to be more convenient.

Description

Portable air foam fire extinguisher
Technical field
The utility model 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 water-insoluble burning inflammable, flammable, the liquid that can scatter is extinguished.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 made in addition.The Chinese patent application of being submitted in 2008 by applicant 200810140306.1 discloses a kind of air-foam fire extinguisher, said air-foam fire extinguisher is a kind of backpack fire extinguisher, comprise 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 by sebific duct and fire foam bucket, it comprises that also double end is external, the fluid by-pass valve control, double end connects silk, collector, the imbibition chamber, disperse baffle plate, copper sheathing, nozzle and foaming tube, said fire foam is packed in the backpack extinguishing chemical bucket, and the extinguishing chemical bucket links by the imbibition joint of sebific duct and air-foam fire extinguisher.During use, the extinguishing chemical bucket is carried on the back on user's shoulder, the pipe tooth that fire extinguisher canvas hose is connected on air-foam fire extinguisher connects to be buckled, the tube subtend that will foam ignition zone, open fire extinguisher canvas hose, to go out hydraulic control valve opens gradually, the water of High Voltage will connect by the pipe tooth and tip in into collector, sucks fire foam from the imbibition joint, disperses baffle plate by frustum, enter nozzle, form powerful pressure, mix the foam that the back forms with inhaled air, diffusion atomizing immediately, 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 water-insoluble inflammable of burning, flammable, can the scatter surface of liquid, make it and contain the air insulated of oxygen that can be combustion-supporting, thereby burning is extinguished.But, in use there are several problems in said foam annihilator: 1, froth liquid vessel must be connected use with said foam annihilator, the necessary portable foam annihilator of fire fighter, the portable froth liquid vessel of another, perhaps carry and operate, make troubles for on-the-spot fire extinguishing by two fire fighters; 2,, not very convenient in scene of fire carrying and use 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; 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 solutions of the utility model are finished, not seeing the portable air foam fire extinguisher identical with the utility model structure uses in daily life, not seeing the portable air foam fire extinguisher identical with the utility model structure has sale on market, it is on the books in the literature also not see the portable air foam fire extinguisher identical with the utility model structure.
