Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0024] see Figure 1-4 , the present invention comprises muffler barrel, air intake duct 8, exhaust duct 5, silk screen 7, baffle plate 4; And silk screen 7 adopts barbed wire; The muffler housing 2 of the rear end cover 1 is equipped with an air intake duct 8 on the front end cover 9 and an exhaust duct 5 is installed on the rear end cover 1 .

[0025] The main pipe is welded in the muffler shell 2, and the main pipe divides the muffler cylinder into three parts: the upper chamber, the flow chamber and the lower chamber, and the air inlet conduit 8 is connected with one end of the flow chamber, and the exhaust The conduit 5 communicates with the other end of the flow chamber. The main pipe is composed of a baffle 4 and a pipe with a notch on the pipe wall. One end of the baffle 4 and one end of the pipe are respectively welded to one end of the muffler she...

Abstract

An oil-gas separation muffler for compressors, including a muffler cylinder and a main pipe welded in the muffler cylinder with oil discharge holes. The main pipe divides the muffler cylinder into an upper chamber, a flow chamber and a lower chamber. The chamber has three parts, and one end of the muffler cylinder is provided with an air intake conduit connected to one end of the main pipe, and the other end is provided with an exhaust conduit connected to the other end of the main pipe; Separated wire mesh, and the wire mesh is connected with the intake pipe; the pipe wall of the main pipe is provided with several groups of branch pipes for weakening the noise in the 0.8k-2.5kHz frequency band, and several groups of branch pipes are arranged at intervals along the axial direction of the main pipe On the main pipeline, the lengths of each group of branch pipes are different, and each group of branch pipes communicates with the main pipeline. The muffler of the invention not only achieves the purpose of absorbing noise, but also can separate oil and gas.

Description

technical field [0001] The invention relates to an oil-gas separation muffler, in particular to an oil-gas separation muffler used for a compressor. technical background [0002] During the working process of the compressor, its noise sources are relatively complicated. In summary, they mainly come from three categories: mechanical noise, aerodynamic noise and electromagnetic noise. [0003] In the piston compressor, the mechanical noise is caused by the reciprocating inertial force and the rotating inertial force, which is also the main cause of the vibration and noise of the compressor. Aerodynamic noise is generated by the vibration of air caused by the flow of gas or the movement of objects in gas. In the refrigeration compressor, due to the intermittent suction and exhaust, the gas pressure fluctuates, causing the pipeline to vibrate, thus generating noise. In addition, the vibration of the compressor body excites the refrigerant gas in the shell to resonate, which al...
