Large-discharge-capacity silent exhaust pipe

Abstract

The invention discloses a large-discharge-capacity silent exhaust pipe. The large-discharge-capacity silent exhaust pipe comprises a gas inlet pipe. The top end of the gas inlet pipe is fixedly connected with the bottom end of a blowing pipe. An inner cavity of the blowing pipe communicates with an inner cavity of the gas inlet pipe. The inner wall of the blowing pipe is fixedly connected with a hack lever. One end of the hack lever is fixedly connected with the surface of a gas cutting block, the top of the gas cutting block is fixedly connected with the bottom of a fixing cylinder, steel balls are arranged in an inner cavity of the fixing cylinder, one end of a rotating shaft penetrates the top of the fixing cylinder, and the end of the rotating shaft extends into the inner cavity of the fixing cylinder. By means of the large-discharge-capacity silent exhaust pipe, after waste gas enters the blowing pipe through the gas inlet pipe, due to the relatively large air pressure, the gas flow generated through the air pressure will be used for enabling blades to rotate so that the blades can produce suction force on the waste gas, the waste gas is sucked by the suction force produced by the blades, the ventilation capacity of the blowing pipe is improved, the situation that the waste gas blockage of the exhaust pipe is caused as the waste gas ascends sharply in the exhaust pipe is prevented, and noise caused when the waste gas is exhausted out of the exhaust pipe is avoided.

Description

technical field [0001] The invention relates to the technical field of exhaust pipe silencer, in particular to a large-displacement silencer exhaust pipe. Background technique [0002] The exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter that controls the emission of engine pollutants is also installed in the exhaust system. The exhaust The pipe generally includes a front exhaust pipe and a rear exhaust pipe. Although some pipes used to discharge exhaust gas can complete the exhaust work, but in the process of exhausting, if the air pressure in the exhaust pipe is too high, the exhaust gas will not be discharged in time in the trachea sharply, but the air pressure in the trachea will reach a certain level. Exhaust gas rushes out of the air pipe, and the exhaust gas can cause a burst sound when expelled sharply, causing the machinery u...
