Description

Tail gas silencing pipe for mining machinery

Technical Field

The invention relates to a tail gas silencing pipe used for mining machinery, and belongs to the technical field of mining machinery.

Background

The tail gas silencing pipe used for the mining machinery is used for generating less noise caused by tail gas emission in operation and realizing the function of greatly reducing the equipment use interference in the environment, but the tail gas silencing pipe used for the mining machinery at the present stage belongs to a vertical pipeline in use, the outlet end of an exhaust pipe is connected with a silencing component, and a straight structure of the exhaust pipe has obvious technical defects in weakening noise or buffering exhaust pressure, so that the tail gas silencing pipe has great interference effect on the tail gas emission.

Disclosure of Invention

In view of the problems in the prior art, the invention provides a tail gas silencing pipe for mining machinery, which is provided with a bending shape arranged on an internal silencing pipe to increase the exhaust area of tail gas emission, and a plurality of through holes arranged in the exhaust process, so that the exhaust area is increased, the noise generated by gas pressure is reduced, and a heat insulation layer and a sound insulation layer are arranged on a pipe fitting to increase the safe use of the silencing pipe fitting and further realize the silencing effect.

In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides a tail gas amortization pipe that mining machinery used, includes clean system, amortization inner tube, amortization outer tube, asbestos outer tube, sealed neck ring one and sealed neck ring two, clean system's fixed surface be connected with the surface of amortization inner tube, the outside fixed surface of amortization inner tube be connected with the amortization outer tube, the outside surface of amortization outer tube cup jointed the asbestos outer tube, amortization inner tube and amortization outer tube homonymy one end joint of meeting be connected with sealed neck ring one, amortization inner tube and amortization outer tube homonymy other end joint of meeting be connected with sealed neck ring.

The surface of the silencing inner pipe is provided with a plurality of through holes, and the silencing inner pipe is a bent pipeline.

And heat insulation particles are arranged in an interlayer between the asbestos outer pipe and the silencing outer pipe.

The first sealing collar and the second sealing collar are both made of nano carbonized structures.

In summary, the present invention provides a tail gas silencing pipe for mining machinery, which has a curved shape on an internal silencing pipe to increase the exhaust area of tail gas emission, and has a plurality of through holes in the exhaust process, so as to increase the exhaust area and reduce the noise generated by gas pressure.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1 to 3, the invention is a tail gas silencing pipe used in mining machinery, comprising a purification system 1, a silencing inner pipe 2, a silencing outer pipe 3, an asbestos outer pipe 4, a first sealing collar 5 and a second sealing collar 6, wherein the surface of the purification system 1 is fixedly connected with the surface of the silencing inner pipe 2, the outer surface of the silencing inner pipe 2 is fixedly connected with the silencing outer pipe 3, the outer surface of the silencing outer pipe 3 is sleeved with the asbestos outer pipe 4, the joint of one ends of the same sides of the silencing inner pipe 2 and the silencing outer pipe 3 is connected with the first sealing collar 5 in a clamping manner, and the joint of the other ends of the same sides of the silencing inner pipe 2 and the silencing outer pipe 3 is connected with the second sealing.

The surface of the silencing inner pipe 2 is provided with a plurality of through holes 7, and the silencing inner pipe 2 is a bent pipeline.

And heat insulation particles 8 are arranged in an interlayer between the asbestos outer pipe 4 and the silencing outer pipe 3.

The first sealing collar 5 and the second sealing collar 6 are both made of nano carbonized structures.

In summary, the present invention provides a tail gas muffler for mining machinery, which has a curved shape on an internal muffler to increase the exhaust area of the tail gas, and has a plurality of through holes during the exhaust process, thereby increasing the exhaust area and reducing the noise generated by the gas pressure.
