Abstract
The utility model relates to the foaming-generating unit, to be specific, a foaming-generating unit with water wheel nozzle. This utility model is characterized in that: it comprises the impeller (1) of air blower, slant nozzle (2), central nozzle (3), foam-generating net (4), shell body (5), hollow axis (6) and nozzle stand (7). The hollow axis (6) is connected to the nozzle stand (7); impeller (1) of air blower is installed in the hollow axis (6) behind the nozzle stand (7); central nozzle (3) is set at the center of the nozzle stand (7); slant nozzle (2) is connected to the circumference of the nozzle stand (7); foam-generating net (4) is connected to the front section of the shell body (5); 2-10 slant nozzles (2) are adopted. This utility model has the advantages of: simple structure, low cost, outstanding performance in safety and reliability, convenient application, light weight and great volume for foam generation. It can reach to the technical indices as follows: foaming rate: 140-200m <3> virgule minute; expansion rate of foaming: 700-9,000; water consumption rate: 230-270v virgule minute; mixing ratio: 3-4.6%; weight: 23kg.
Description
Technical field: the utility model relates to device, is specially a kind of foam maker device, is specially a kind of water wheel type nozzle foam maker device.
Background technology: at present, be a kind of New Type Fire-fighting Device of fire prevention in modern age in China or foreign country's employing hydro powered high-expansion foam generator.But existing hydro powered high-expansion foam generator exists, and volume is big, Heavy Weight, structure heaviness and the little shortcoming of gas release.
Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, with low cost, safe and reliable, in light weight, water wheel type nozzle foam maker device that gas release is big, easy to use.The purpose of this utility model is achieved in that it comprises draught fan impeller (1), oblique nozzle (2), central nozzle (3), foam screen (4), housing (5), hollow shaft (6), nozzle boss (7).Hollow shaft (6) is connected with nozzle boss (7), on the back of nozzle boss (7), hollow shaft (6) draught fan impeller (1) is arranged, and the center of nozzle boss (7) has on the circumference of central nozzle (3), nozzle boss (7) and is connected with oblique nozzle (2); Be connected with foam screen (4) in housing (5) the place ahead.Tiltedly nozzle (2) is 2-10.The utility model has the advantages that: simple in structure, with low cost, safe and reliable, easy to use, in light weight, gas release is big.Can reach following technical indicator: frothing percentage 140-200m
3/ minute, coefficient of foaming 700--900, water consumption rate 230-270v/ minute, mixing ratio 3-4.6%, weight 23kg.
Description of drawings: Fig. 1 looks schematic diagram for the utility model structural principle master; Fig. 2 looks schematic diagram for the right side that the utility model structural principle does not have foam screen.
The specific embodiment: hollow shaft (6) is connected with nozzle boss (7), on the back of nozzle boss (7), hollow shaft (6) draught fan impeller (1) is arranged, and the center of nozzle boss (7) has on the circumference of central nozzle (3), nozzle boss (7) and is connected with oblique nozzle (2); Be connected with foam screen (4) in housing (5) the place ahead.Tiltedly nozzle (2) is 2-10.The utility model course of work: mixed liquor is injected oblique nozzle and central nozzle through hollow shaft and nozzle boss under pressure, evenly be sprayed onto on the foam screen again, order about the nozzle boss rotation from the mixed liquor of oblique nozzle ejection, drive coaxial draught fan impeller thus and rotate air blast, on foam screen, form the fire extinguishing high power foam together with mixed liquor.Central nozzle is made up of helicla flute post and recessed housing, and said foam screen can be that a kind of stretching is foam screen, and the single liquid stream of the utility model origin of an incident spray bubble drives blower fan.The utility model is the extinguishing device that is used for fixing the formula high-expansion foam extinguishing system, and volume is little, in light weight, it is few to consume liquid measure, gas release can pack into greatly in the wall as fixed fire extinguisher also removable use put out a fire to save life and property large tracts of land category-A, category-B fire.
