Noise processing device

Abstract

The invention discloses an industrial noise treatment device. The device comprises a shell and a bottom plate, silencing holes are formed in the inner wall of the shell and the top surface of the bottom plate, the shell is divided into a front chamber and a silencing chamber, the silencing chamber is connected with an outlet pipe with an upward opening, a partition plate is arranged in the front chamber, a stepped hole is formed in the center of the partition plate, a movable filter cartridge is arranged in the stepped hole, a moving mechanism is arranged at the lower part in the front chamber, the moving mechanism comprises a bearing seat, a screw rod, a moving block and a driver, a fan is arranged in the silencing chamber, a jacking mechanism is arranged in the front chamber, a first sound insulation layer is arranged outside the shell, and a second sound insulation layer is arranged outside the outlet pipe. Compared with the prior art, the device has the beneficial effects that thedraught fan can work to suck air inwards, external air with noise can enter the silencing chamber conveniently to be silenced through the silencing holes, the filter cartridge is arranged on an inevitable path of air flowing to be used for intercepting dust, flocculent floating objects and the like so as to protect the silencing holes and ensure that the silencing holes can work normally, and meanwhile the filter cartridge is more convenient to clean.

Description

technical field [0001] The invention relates to a processing device, in particular to a noise processing device used in industry for reducing noise. Background technique [0002] Noise is likely to be generated in industrial production, which is harmful to the external environment and the physical and mental health of the surrounding staff. Therefore people devote themselves to solving this problem and invented the noise treatment device. The existing noise treatment device sucks the gas by the fan, and the gas contains a lot of noise along with the flow direction, and the noise is eliminated through the sound-absorbing hole, so as to achieve the purpose of reducing the noise. Due to the large amount of dust and flocculent floating objects in the industrial environment, in this way, the dust and flocculent floating objects are easy to fall into the sound-absorbing hole and affect its working effect, and the filter screen installed at the entrance is easy to block the filt...
