Description
One, technical field:
The utility model belongs to a kind of portable fire-extinguishing apparatus, particularly has a kind of portable geomantic omen spray of air-discharging and supercharging device.
Two, background technology:
At present, countries in the world are every to be the various Fire extinguisher apparatus of power with miniature gasoline engine, as the wind-force sprinkling fire machine of " wind-force dust spraying machine ", " wind-force spraying machine " and China (hereinafter to be referred as: the geomantic omen spray) etc., in order to guarantee fluid or the flour in water receiver or the explosive box, entering spraying canister ejection fast, all is to adopt to connect wireway from a part of blower fan and be communicated with water receiver or explosive box usually.Blower fan is when work, telling a part of high pressure draught by the connection wireway enters in water receiver or the explosive box, make the internal pressure in water receiver or the explosive box and the pressure of spraying canister reach balance, thereby make fluid in water receiver or the explosive box or flour flow into spraying canister, then the high velocity air that produces by the blower fan function that gushes out and finish water spray, spray, dust along the carrier pipe that connects spraying canister.This method is " branch mobile equilibrium " method.This method from the blower fan shunting though realized the sprinkling function, is a cost with reduction blast, wind speed, air quantity, for portable or geomantic omen spray, will reduce spray rate like this, thereby speed reduces fire extinguishing effect and speed.Therefore, present stage presses in fire extinguishing and solves the problems referred to above that portable geomantic omen spray exists.
Three, utility model content:
The purpose of this utility model is intended to address the above problem, at the prior art that causes geomantic omen spray spray rate to reduce because of " branch mobile equilibrium ", design provides a kind of simple in structure, easy to use, cost is low, and air-discharging and supercharging is effective, increase the internal pressure of geomantic omen spray water receiver, accelerate the water flow velocity in the carrier pipe, the spray rate height has the portable geomantic omen spray of air-discharging and supercharging device.
The technical solution of the utility model is achieved by following manner: a kind of portable geomantic omen spray, comprise air duct 1, the draught fan impeller 5 of volute of blower 2 and interior setting thereof and forward and backward dish 10 and 4, fan impeller blade 6, the gasoline engine 9 that is connected with volute of blower 2 and on air-cooled cover 3 and muffler 13, and handgrip 15 and switch 16, it is characterized in that: muffler 13 sides at gasoline engine 9 are provided with the air-discharging and supercharging device, as shown in Figure 1, 2.
Isocon 17 that said air-discharging and supercharging device is communicated with by the housing with muffler 13 and cooling tube 19 and the connecting bend of the two 18, air duct fitting 20 are formed, wherein, cooling tube 19 is arranged in the air duct 1, one end of isocon 17 is communicated with the housing of muffler 13, the other end of isocon 17 is communicated with cooling tube 19 in being arranged on air duct 1 by elbow 18, and cooling tube 19 passes through air duct fitting 20 and is communicated with water receiver or explosive box.As shown in Figure 1, 2.
Operation principle of the present utility model and process are: the high pressure exhaust gas that oneself is discharged as the miniature gasoline engine 9 of power with the geomantic omen spray, air duct fitting 20 by " air-discharging and supercharging " device connects wireway and is incorporated in the water receiver, thereby the internal pressure of water receiver is increased, water velocity in the carrier pipe is accelerated, thereby improved spray rate and injection flow rate, reached the purpose of quick extinguishing.The concrete course of work is the high pressure exhaust gas that produces during with gasoline engine 9 work of geomantic omen spray, be incorporated into cooling tube 19 from muffler 13 by isocon 17 and connecting bend 18, the high velocity air that produces by blower fan is cooled off, cooled high pressure exhaust gas enters water receiver by the wireway that air duct fitting 20 connects again, reaches the purpose of " air-discharging and supercharging ".
Present technique is compared with prior art, have simple in structure, easy to use, cost is low, at the limited blast that has guaranteed that blower fan produced, under the prerequisite of air quantity and wind speed, increase the internal pressure of geomantic omen spray water receiver, make the air-discharging and supercharging process in the water receiver safe and reliable, injection flow rate keeps continous-stable in the sprinkling process, improve water velocity and spray rate in the carrier pipe, thereby improved characteristics such as blow-off velocity.
