A noise reduction and environmental protection muffler for small tonnage internal combustion vehicles

Abstract

The invention discloses a noise reduction and environmental protection muffler for a small tonnage internal combustion vehicle, comprising a cylinder body, two ends of the cylinder body are respectively connected with an air inlet end and an air outlet end, and the inner wall of the left end of the air outlet end is rotatably connected by a torque shaft There is a baffle plate, a plurality of mufflers are arranged inside the air outlet, a vertical slide plate is slidably inserted on the cylinder body, and two installation ports are opened at the lower end of the slide plate, and the two installation ports are A mesh plate is installed, an extension end is integrally formed on the lower side wall of the cylinder, the lower end of the slide plate extends into the extension end, a motor is fixedly connected above the cylinder, and a driving end of the motor is fixedly connected with a Chainring. The invention ensures the degree of noise reduction and is more environmentally friendly by performing multi-stage elimination, absorption and noise reduction treatment on the exhaust gas, and vibrates the screen plate through the movement of the sliding plate and the impact plate to accelerate the falling of impurities and ensure the normal filtering and noise reduction of the screen plate. Effect.

Description

technical field [0001] The invention relates to the technical field of internal combustion vehicles, in particular to a noise reduction and environmental protection muffler for small tonnage internal combustion vehicles. Background technique [0002] A diesel locomotive uses an internal combustion engine as the motive power and drives the wheels to rotate through a transmission. According to the fuel type of the internal combustion engine on the locomotive, most of the diesel locomotives used on the railways in our country are equipped with diesel engines. The fuel (diesel) is burned in the cylinder, and the heat energy is converted into mechanical energy output by the diesel crankshaft, but it is not used to directly drive the moving wheels, but is converted into mechanical energy suitable for the traction characteristics of the locomotive through the transmission device, and then drives the moving wheels of the locomotive through the running part. Rotate on the track. ...

AI Technical Summary

Problems solved by technology

[0003] The noise of the internal combustion engine mainly includes mechanical noise, gas dynamic noise and combustion noise. Since the fuel of the diesel locomotive is diesel, the deflagration force of diesel is much greater than that of gasoline, so the noise generated by the internal combustion engine is relatively obvious, and an external muffler is needed to eliminate the noise. To achieve noise reduction and environmental protection, and the current muffler will filter and silence through the internal mesh filter plate, etc., but the accumulation of insufficiently combusted substances in the exhaust gas or the blockage of the mesh plate and filter plate will affect the passage of airflow , which in turn affects the exhaust gas filtration and noise reduction effect
