Noise absorbing device for vacuum pump

Abstract

The invention comprises a noise absorbing device for a vacuum pump. The noise absorbing device comprises a base plate, a housing and more than one stage of heat dissipation components, wherein the housing is fixedly arranged on the top of the base plate, and each stage of heat dissipation components is fixedly arranged on the outer surface of the housing respectively; each stage of heat dissipation components comprises a temperature controller, an air draft device, an air supply device, a radiating pipeline and a radiator respectively; the temperature controller is fixedly arranged in the housing, the air draft device and the air supply device are obliquely and fixedly on the outer surface of the housing in a sealing mode at an interval, the air draft device and the air supply device are electrically connected to the temperature controller respectively, the radiator is fixedly arranged on the outer surface of the housing between the air draft device and the air supply device, and the two ends of the radiating pipeline are connected to the air draft device and the air supply device respectively in the sealing mode, and the middle part of the radiating pipeline is tortuously embedded in the radiator; moreover, a through hole for connecting the vacuum pump with the outside is further formed in the housing. The noise absorbing device can not only reduce the noise pollution of the vacuum pump effectively but also dissipate heat for the vacuum pump effectively.

Description

technical field [0001] The invention relates to a noise absorbing device, in particular to a vacuum pump noise absorbing device. Background technique [0002] Analytical laboratories are usually equipped with mass spectrometers and liquid chromatography mass spectrometers. Since these analytical instruments have high requirements for vacuum, they are usually used in conjunction with high-power vacuum pumps. Although the high-power vacuum pump effectively meets the vacuum requirements of these analytical instruments, it also brings serious noise pollution. Working in such a strong noise environment for a long time will greatly affect the health of experimenters or scientific researchers. harm. [0003] In the prior art, there is a kind of sound-proof cover. Placing the vacuum pump inside the sound-proof cover can reduce the noise pollution to a certain extent, but the opening provided for the fan on this sound-proof cover will not only allow dust to enter the sound-proof cov...

Although the high-power vacuum pump effectively meets the vacuum requirements of these analytical instruments, it also brings serious noise pollution. Working in such a strong noise environment for a long time will greatly affect the health of experimenters or scientific researchers. harm

[0003] In the prior art, there is a kind of soundproof cover. Placing the vacuum pump inside the soundproof cover can reduce the noise pollution to a certain extent, but the opening provided for the fan on the soundproof cover will not only allow dust to enter the soundproof cover, but also cause Other serious problems, and it will also cause noise leakage, resulting in a greatly reduced sound insulation effect of the sound insulation cover
