Description

Technical Field

[0001] The utility model relates to the technical field of air blast noise reduction, in particular to a noise reduction device for a high-pressure blower. Background Art

[0002] High-pressure blowers are most common in factory workshops and are used very frequently. In order to isolate the noise of high-pressure blowers, most of them are now placed in a soundproof box to achieve the purpose of noise reduction.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the sound insulation box of the noise reduction device of the existing high-pressure blower is mostly an integrated design, and when the high-pressure blower is stopped and no noise reduction is required, the sound insulation box is still covered on its outside, and relies on the blower on one side for blowing air to dissipate heat. This kind of situation has insufficient heat dissipation, which will affect the service life of the high-pressure blower body in the long run, and it is urgently needed to be improved. Therefore, we propose a noise reduction device for a high-pressure blower. Utility Model Content
