Split type exhaust good in noise reduction effect

Abstract

The invention relates to the technical field of exhaust equipment and discloses a split type exhaust good in noise reduction effect. The split type exhaust comprises a bottom shell. An air outlet pipepenetrates through the left side of the bottom shell. A seal plate is fixedly installed at the top of the bottom shell. A top cover is connected to the top of the seal plate in a clamped mode. The top of the top cover is provided with an air vent. An air inlet pipe penetrates through the left side of the top cover. Silencing cotton is fixedly installed on the left side wall in a cavity of the topcover. A silencing box is fixedly installed on the inner side of the silencing cotton. A fixed frame is fixedly installed on the outer side of the silencing box. An installation seat is fixedly installed on the right side of the silencing cotton. An exhaust fan is fixedly installed on the right side of the installation seat. A sound insulation plate is fixedly installed on the right side of the exhaust fan. An air blower penetrates through the top of the seal plate, and one end of the air blower is located in a bottom shell cavity. An air pipe located in the bottom shell cavity communicates with the bottom of the air blower. The split type exhaust good in noise reduction effect is good in noise reduction effect, and body safety of staff is protected.

Description

technical field [0001] The invention relates to the technical field of exhaust equipment, in particular to a detachable exhaust pipe with good noise reduction effect. 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. [0003] Environmental noise standards are regulations on the allowable range of noise to protect the health of the population and the living environment. The principles should be based on the protection of people's hearing, sleep, rest, and conversation and thinking. They should be advanced, scientific, and realistic. Noise can have adverse effects on people's physiology and psychology. In daily work and living envir...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a detachable exhaust pipe with good noise reduction effect, which has the advantages of good noise reduction effect, etc., and solves the problem that the wind speed passes through the pipe quickly when the exhaust pipe is exchanging air. It produces very high decibel noise, which greatly interferes with the surrounding environment. If the staff is in a high-noise environment for a long time, it will cause great damage to the body and seriously affect health problems.
