Abstract

The invention discloses a structure of an exhaust silencing pipe. The structure of the exhaust silencing pipe is provided with a positive spiral leaf axis and a negative spiral leaf barrel, wherein the external circle surface of the negative spiral leaf barrel is fixed on an exhaust pipe, and the positive spiral leaf axis is fixed on the middle part of the exhaust pipe by a support; and when the positive spiral leaf axis and the negative spiral leaf barrel are installed, the spiral directions of the positive spiral leaf axis and the negative spiral leaf barrel are opposite. Because the scheme is adopted, the structure of the exhaust silencing pipe has the advantages of high silencing quantity, low resistance, simple structure, high safety and reliability in use, wide application range, low fault rate and no maintenance, also has the advantages of the exhaust pipe function and the silencing function, and overcomes the defects that the silencer has high resistance and a complex structure and small holes are easily blocked.

Description

Technical field: [0001] The invention relates to an exhaust muffler pipe, in particular to a structure of an exhaust muffler pipe, and belongs to the technical field of muffler. Background technique: [0002] As we all know, the noise elimination principles currently applied in chemical industry, petroleum, metallurgy, electric power, automobile, boiler and other industries mainly include throttling and decompression and small hole tail blocking. Tail muffler and the combination of the two, the above three kinds of mufflers have the following deficiencies respectively, 1, the resistance is relatively large; 2, the structure is complicated; 3, the defect that small holes are easy to block. Invention content: [0003] The object of the present invention is to provide a structure of the exhaust muffler pipe, which overcomes the defects of the above muffler, such as relatively large resistance, complex structure, and easy blockage of small holes. [0004] The technical soluti...
