Automobile exhausting spark arrester

Abstract

The invention discloses an exhaust spark blow-out device. The casing of the spark blow-out device is provided with an gas inlet annular tube and a gas outlet, a longitudinal center shaft is arranged along the front and rear directions of the casing, a handle is fixedly connected on the rear end of the center shaft, a stretching device is arranged on the inner cavity of the gas inlet annular tube and is engaged with the front portion of the center shaft, the center shaft is operated by the handle to control the closure and open of the stretching device, and a rotating fire blade wheel is fixed on the rear portion of the center shaft. The stretching device presses tightly or separates from the inner walls of a discharge pipe of automobile to realize the fast, convenient, labor-saving and time-saving loading and unloading of the exhaust spark blow-out device of automobile and to realize the firm and reliable installation, exhaust gas can drive the rotating fire blade wheel which is perpendicular to the center shaft to rotate, thereby effectively reducing the temperature and the pressure of exhaust gas, and decreasing the impulse of the pressure for exhausting gas, and the effect of blow-out spark is excellent, the exhaust gas flows out smoothly, and the exhaust resistance and the power loss are smaller.

Description

technical field [0001] The invention relates to a device for eliminating engine exhaust sparks, in particular to a motor vehicle exhaust spark extinguisher. Background technique [0002] Motor vehicles must wear a motor vehicle exhaust spark arrester when entering a fire-free zone. In the prior art, the temporarily connected motor vehicle exhaust spark extinguisher uses metal wires to bind it on the exhaust tailpipe of the motor vehicle, or has a longitudinal long slot at its air inlet, and utilizes the air intake The elasticity of the mouth makes it clamped on the exhaust tail pipe of the motor vehicle. Although these two installation methods are simple, the connection is not firm, and the motor vehicle exhaust spark extinguisher is easy to fall off and there is a fire hazard. Chinese Patent No. 200620023921.0 "Safety "Fireproof Cap" discloses the technology of installing a bolt clamping hoop at the longitudinal slot at the air inlet end of the safety fireproof cap, and us...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the shortcomings of the existing motor vehicle exhaust spark extinguisher, the connection is not firm and easy to fall off or it is difficult to install and disassemble, and the time is long; and the motor vehicle exhaust spark extinguisher has large exhaust resistance and large power loss; exhaust gas cooling is not enough sufficient, the effect of extinguishing the spark is not good, the exhaust gas flow is not smooth, the residual exhaust gas in the engine cylinder increases, and the power and torque of the engine decrease. Air resistance and power loss are small, the effect of extinguishing sparks is good, and the exhaust gas flows out smoothly. Motor vehicle exhaust spark extinguisher
