Background
The air compressor is widely used mechanical equipment, in particular to a piston type air compressor, and is more commonly used power equipment in various industries. However, when the air compressor is used, the exhaust sound is very loud, so that the common practice in the industry is to add silencers at the air inlet and the air outlet. The mufflers are of various types, but the muffling mechanism is considered, and the mufflers can be divided into six main types, namely resistive mufflers, reactive mufflers, resistive composite mufflers, micro-perforated plate mufflers, small-hole mufflers and active mufflers. At present, impedance load type mufflers are mostly used on air compressor equipment. Such mufflers are generally relatively complex in construction and relatively costly.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an air compressor exhaust muffler is the combination of impedance combined type silencer and micropunch plate silencer, has mainly solved impedance combined type silencer and has blockked more to gas, the more gaseous kinetic energy of loss, the problem of extra the multiple consumption energy, when weakening gas impedance, adds the board-like noise elimination of micropunch and compensaties and strengthen.
The above technical problem of the present invention can be solved by the following technical solutions: the air inlet pipe is characterized by comprising an air inlet pipe, a shell and an air outlet pipe, wherein a flaring pipe is arranged at one end of the air inlet pipe, a support is arranged at the large opening end of the flaring pipe, a guide post is arranged in the middle of the support, a spring is sleeved outside the guide post, one end of the spring is fixed on the support, the other end of the spring is fixedly connected with a wind shield, the wind shield is simultaneously connected with the guide post in a sliding manner, a connecting piece is arranged outside the large opening end of the flaring pipe, a connecting piece is also arranged outside the shell, the flaring pipe and the shell are fixedly connected through two connecting pieces and bolts which are matched with each other, a plurality of wind shielding net plates which are perpendicular to the air inlet and outlet directions are arranged in the shell, a plurality of groups of air guide pipes are also perpendicularly arranged on the wind shielding net plate closest to the air inlet in the, the wind shielding net plate and the ventilation catheter are both provided with sieve pores, the other end of the shell is fixedly connected with a gas outlet pipe, the wind shielding net plate is also arranged in the gas outlet pipe, and a flange is arranged on the outer side of the gas outlet pipe.
Preferably, the wind deflector is provided with screen holes to reduce the impedance to the gas and reduce the blocking noise inside the muffler.
Preferably, the inner side of the air inlet pipe is provided with internal threads.
Preferably, soundproof cotton interlayers are arranged on the inner wall of the flared tube and the inner wall of the chamber in contact with the shell.
The utility model has the advantages that: and sieve pores are added to the impedance component inside the silencer, so that the impedance of the gas is milder, and meanwhile, the micro-perforated plate type silencing is added, so that the integral silencing effect is enhanced.
