Abstract
The high-energy blower fan for extinguishing fire comprises fan shell, air cylinder, blade wheel, rubbing ring and end cover, which is characterized by adopting special design of fan shell and blade wheel structure to retain the original air channel and blast volume, at the same time to recover the air flow for cooling air force fire-extinguishing engine and discharge waste gas into swirl chamber of fan to form stronger air flow to directly extinguish fire. Said blower fan not only can raise air speed and blast volume, but also can thin oxygen gas concentration in the fire-extinguishing air flow and raise extinguishing effect.
Description
Technical field: the present invention relates to Pneumatic extinguisher, specifically Cyclonic powderful blower for fire extinguishing.
Background technique: at present, be used to put out the woods fire Pneumatic extinguisher, in use, have the following disadvantages: the one, air quantity is little, and wind speed is low, and the 2nd, the engine cooling weak effect, the 3rd, the waste gas that motor is discharged is discharged and is dissipated in the air from outlet pipe, causes atmospheric pollution.
Summary of the invention: the objective of the invention is to, design a kind of matching used with motor, starting is fast, wind-force big, by cooling system ground is improved, strengthen cooling effect, high engine speeds prolongs running time at double, wind-force fire extinguishing motor is used for the waste gas of self cooled gas flow and discharge, all be recovered in the blower fan vortex chamber, merge into powerful air-flow, discharge, be directly used in the Cyclonic powderful blower for fire extinguishing of fire extinguishing through air duct.Its major technique content is, Cyclonic powderful blower for fire extinguishing, by Fan casing, air duct, impeller, rubber ring, end cap constitutes, it is characterized in that, the Fan casing inwall, be provided with an air-flow envelope and cut ring, have one and cylinder, the corresponding rear air inlet in outlet pipe position and a central shaft hole, Fan casing front air outlet place, the hinge of two band hinge lasts is housed, in the Fan casing, is equipped with an impeller that links to each other with engine shaft, the dull and stereotyped center of impeller, be provided with the center screw that is connected with engine spindle, outward edge, being provided with right angle endless belt and Fan casing inwall air-flow envelope, to cut ring overlapping with a gap, dull and stereotyped in the right angle endless belt, be provided with some strips hole, on the strip hole, correspondence is provided with the edge-on hypsokinesis blade of rotary-cuting type, the dull and stereotyped and front side dish endless belt of impeller, big blade and the small leaf antecurvature by hypsokinesis connect, present oblate cylindricality, outside the Fan casing, be provided with a rubber ring and an end cap of bringing the air port into.The present invention compares the advanced part that is had and is with prior art, Cyclonic powderful blower for fire extinguishing, have scientific structure, two-way air intake, interflow supercharging, when increasing wind and exhaust air rate, the advantages such as cooling effect of motor have been strengthened again, thereby when having overcome existing centrifugal vortex fan work, existing deficiency.
