Silencing device for drainage pipeline of air compressor

Abstract

The invention relates to a silencing device for a drainage pipeline of an air compressor. The silencing device for the drainage pipeline of the air compressor comprises a silencer provided with a cavity, wherein a drainage port of the drainage pipeline is communicated with the cavity, draining holes communicated with the cavity are formed in the bottom of the silencer, and the cross-sectional area of the cavity is larger than that of the drainage port. The condensed water of the air compressor is drained through the drainage pipeline, the drained water carries out capacity expansion in the cavity of the silencer while flowing in the cavity of the silencer from the drainage port to weaken noise, the condensed water after noise reduction is drained through the draining holes in the bottom of the silencer to meet the requirement of no pressure held at the drainage port, lower the draining noise of the drained water, and greatly improve the working environment of a site; and moreover, the silencing device for the drainage pipeline of the air compressor is simple in structure, capable of reducing an investment cost, suitable for various types of air compressor systems with various discharge pressures only by changing the volume of the cavity of the silencer and the number of the draining holes according to the different discharge pressures, and low in requirements on a space.

Description

technical field [0001] The invention relates to the technical field of drainage of air compressors, in particular to an air compressor drainage pipeline noise reduction device. Background technique [0002] An air compressor is a device that converts the mechanical energy of an electric motor into gas pressure energy, and is a pressure generating device that compresses air. During the compression of the air, the condensed water is discharged through the drain pipe. Since the condensate is discharged under pressure, and the drain must be discharged with an open mouth, that is, the pressure cannot be suppressed at the drain, so there will be very loud noise at the drain of the drain pipe, the noise is continuous and sharp, which greatly affects the site. working environment. Contents of the invention [0003] The object of the present invention is to provide a sound-muffling device for drain pipes of air compressors, which can reduce the noise of drain discharge and improv...
