Abstract

The invention relates to a silencing exhaust device for a high-power engine. A cylinder (7) is in a circular cylinder shape with round end covers (5) at two ends; an intake connecting pipe (1) is connected with an air inlet (4) arranged at the bottom of the cylinder (7) through a pipe connecting flange 1(2) and a pipe connecting flange 2(3); a shoe-shaped sheet (12) is welded on the air inlet (4); an exhaust pipe (9) is arranged at the upper part of the cylinder (7) through an air outlet (8); a thermal baffle (6) is arranged on the outer wall of the cylinder (7); and a microperforated panel (10) is arranged at the air outlet (8) in the cylinder (7). In the invention, the circular cylinder shape with the end covers at two ends reduces the volume of the silencer, the inner structure adopts the microperforated panel technology, a shock-absorbing high-temperature resistant material is filled, the thermal baffle is additionally arranged on the outer wall, thus the silencer has small pressure loss, low regeneration noise and wide silencing waveband, and can bear the impact of higher air speed, thereby reducing the surface temperature of the silencer and prolonging the service life.

Description

technical field [0001] The invention relates to a sound-absorbing and exhausting device for crawler-type hoisting machinery above 1000T. Background technique [0002] With the rapid development of the economy, the country is vigorously building new infrastructure. We can see heavy machinery such as cranes, loaders, graders, and road rollers in each of the large engineering projects, which also indicates that my country's heavy machinery has achieved significant development. With the changes in engineering projects Large, for the heavy machinery industry, the original small-tonnage cranes can no longer meet the needs of production, and larger heavy machinery must be produced to meet the needs of the market. Due to the large engine power of large-scale construction machinery, it causes problems such as loud noise and serious exhaust pollution. The sound-absorbing exhaust device is mainly to solve these problems. Most of the existing products of this type have problems such as...
