Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air compressor used for weaving polyester fabrics. Background Art

[0002] An air compressor is a machine that compresses gas and increases its pressure or transports gas. It is widely used in the industrial field. In the processing of polyester fabrics, air compressors are needed to provide power and air pressure to achieve process requirements such as weaving, cooling and shaping, cleaning and dust removal, driving cylinders and controlling airflow.

[0003] When the air compressor is in use, the work of the compressor and the motor will generate a lot of noise, which will have a certain impact on the internal environment of the workshop during long-term use, forming noise pollution. The workers who stay in the workshop for a long time will cause their hearing to be damaged. In order to solve the above problems, while not affecting the work of the air compressor, eliminate the noise caused by the air compressor during work and avoid the noise affecting the working environment of the workshop. For this reason, we have proposed an air compressor for polyester fabric textile. Utility Model Content

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the utility model provides an air compressor for polyester fabric weaving, which has the following beneficial effects:

[0016] 1. The air compressor for polyester fabric textile has a sound-absorbing structure. When the air compressor is working, the noise generated will enter the interior of the silencer box through the sound guide tube fixedly installed inside the sound-absorbing hole. The conical setting of the sound guide tube can facilitate the noise to enter the silencer box while preventing the noise from leaking out of the sound-absorbing hole. After the noise enters the silencer box, the holes opened on the porous sponge will absorb and differentiate the noise, thereby eliminating the noise and avoiding the influence of the noise.

[0017] 2. The air compressor used for polyester fabric textile has a sound diffusion tube. After the noise passes through the sound absorbing hole, it will enter the inside of the sound diffusion tube, and the noise will be diffusely reflected by the uneven surface of the sound diffusion tube. Then, the noise will be diffused through a number of sound diffusion grooves opened on the sound diffusion tube, so that it will diffuse in the inside of the silencer box, which is convenient for use in noise elimination.

[0018] 3. The air compressor used for polyester fabric textile uses the sound insulation layer. After part of the noise penetrates the noise reduction box and is transmitted to the inside of the protective box, it will contact the sound insulation layer fixedly installed on the inner wall of the protective box. The noise is rebounded and absorbed through a number of grooves opened on the sound insulation layer, thereby eliminating the noise through the silencer groove, which is more practical.
