Abstract

Disclosed is an exhaust silencing tube structure. A front resonator is arranged in a chamber in a barrel. A silencing belt is arranged on one side of the front resonator. A spiral silencing belt is connected with one side of the silencing belt and provided with a porous plate. The porous plate is connected with a rear resonator. Throttling plates are symmetrically arranged upon and below the front resonator, the silencing belt, the spiral silencing belt and the rear resonator. Exhaust tubes are mounted on the throttling plates and fixed upon the barrel.

Description

technical field [0001] The invention relates to a muffler pipe structure, in particular to an exhaust muffler pipe structure, and belongs to the technical field of muffler for mechanical equipment. Background technique [0002] As we all know, the noise reduction principle currently applied in chemical industry, petroleum, metallurgy, electric power, automobile, boiler and other industries mainly includes two aspects of throttling and decompression small hole blocking tail. The muffler and the combination of the two, the above three kinds of mufflers have the following disadvantages: 1. The resistance is relatively large; 2. The structure is complicated; 3. The small holes are easy to block. Contents of the invention [0003] The object of the present invention is to provide an exhaust muffler pipe structure with simple structure, low resistance, no clogging of muffler holes, good muffler effect and wide versatility, so as to overcome the above-mentioned defects of existin...
