Noise reduction device for industrial sites

Abstract

The invention relates to the technical field of industrial site noise reduction. The invention relates to a noise reduction device for industrial sites. The device comprises a main body device, an adjusting device, a noise reduction device and a cleaning device, the top end of the main body device is fixedly connected with the adjusting device; the top end of the adjusting device is fixedly connected with the noise reduction device; one end of the noise reduction device is fixedly connected with the cleaning device; the cleaning device is fixedly connected with the adjusting device; in the present invention, closed-cell foamed plastic, a filter screen, canvas, a noise reduction shell, a perforated plate, a hard fiber plate and the like are arranged; noise generated by production equipmentcan be absorbed through an acoustic board; and then the absorbed noise is transmitted to the noise reduction shell on the upper side and the lower side through a first sound guide pipe, a second soundguide pipe and a third sound guide pipe correspondingly, the noise is processed correspondingly, the noise processing efficiency and effect of the noise reduction shell are improved, the noise processed by the noise reduction shell cannot influence the surrounding working environment, and the noise cannot be transmitted remotely.

Description

technical field [0001] The invention relates to the technical field of noise reduction in industrial sites, in particular to a noise reduction device for industrial sites. Background technique [0002] Noise refers to the sound that affects people's work, study and rest. The feeling of noise varies with each person's hearing, feeling, habits, etc. Therefore, noise is a subjective feeling. Generally speaking, people will affect people's health, conversation or thinking. Sound is called noise, and general industrial sites generally have a lot of equipment, which will generate noise during operation. Therefore, there is an increasing demand for a noise reduction device for industrial sites. [0003] At present, in order to reduce the noise near the factory, it is usually adopted to install double-glazed windows on the windows and close the windows tightly to reduce the noise interference, but in this way, the windows cannot play the role of natural ventilation, resulting in rel...

AI Technical Summary

Problems solved by technology

[0003] At present, in order to reduce the noise near the factory, it is usually adopted to install double-glazed windows on the windows and close the windows tightly to reduce the noise interference, but in this way, the windows cannot play the role of natural ventilation, resulting in relatively low indoor air. Pollution is not conducive to people's health, and the noise generated will affect the staff around the equipment, so there is an urgent need for a factory noise treatment device to deal with factory noise and ensure people's normal life. Therefore, in view of the above problems, a Noise reduction device for industrial site
