Noise pollution not only has adverse effects on the environment, but may also face strict environmental supervision pressure. Usually, in order to reduce the noise pollution in the construction of marine paint spraying pumps, outer shell shields are added to the paint spraying pumps, the number of paint spraying pumps used is reduced, or the paint operation time is adjusted to reduce the impact of paint operation noise on personnel. However, the noise reduction effect of these methods is not obvious, and it may even seriously affect the project production and construction plan. In view of the above problems, a noise reduction and silencing device for marine paint spraying pumps is designed. Summary of the invention

The spiral noise reduction shaft (6) is arranged in the first-stage noise reduction and silencing chamber. The noise reduction filter cotton (3) is arranged in the third-stage noise reduction and silencing chamber.

[0005] The connection interface (1) is connected to the air outlet of the marine paint spray pump (10) via threads.

[0006] The noise generated by the marine paint spraying pump (10) enters the first-stage noise reduction and silencing chamber through the connection interface (1), the spiral noise reduction shaft (6) performs spiral dispersion and flow reduction on the noise entering the first-stage noise reduction and silencing chamber, and then enters the second-stage noise reduction and silencing chamber through the first-stage noise reduction and silencing chamber orifice plate (9), the noise entering the second-stage noise reduction and silencing chamber undergoes secondary noise reduction through the second-stage noise reduction and silencing chamber orifice plate (7) and then enters the third-stage noise reduction and silencing chamber, the noise entering the third-stage noise reduction and silencing chamber passes through the noise reduction filter cotton (3) and is discharged through the orifice plate of the shell end cover (4).
