Abstract

The invention relates to an exhaust and silencing pipe device which consists of an exhaust pipe, a support frame, a positive spiral blade shaft, a reverse spiral blade barrel and a silencing pipe body; the exhaust and slicing pipe is provided with the positive spiral blade shaft and the reverse spiral blade barrel which are manufactured; the outer circle surface of the reverse spiral blade barrel is installed and fixed inside the exhaust pipe; the positive spiral blade shaft is installed at the middle part of the exhaust pipe by the support frame; and when the positive spiral blade shaft and the reverse spiral blade barrel are installed, the spiral rotation directions of the positive spiral blade shaft and the reverse spiral blade barrel are opposite.

Description

technical field [0001] The invention relates to a muffler pipe device, in particular to an exhaust muffler pipe device, which belongs to the technical field of exhaust muffler. Background technique [0002] As we all know, the noise reduction principle currently used in chemical industry, petroleum, metallurgy, electric power, automobile, boiler and other industries mainly has two aspects: throttling, decompression and small hole blocking tail. Common forms of mufflers include throttling and decompression mufflers, small-hole tail-blocking mufflers and a combination of the two. The above three types of mufflers have the following disadvantages respectively: 1, the resistance is relatively large; 2, the structure is complex; 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 device with small resistance, simple structure and good noise reduction effect, which overcomes the defec...
