Sound insulation and noise reduction FFU draught fan filtering protection mechanism

Abstract

The invention discloses a sound insulation and noise reduction FFU draught fan filtering protection mechanism which comprises a draught fan sound insulation cover, an air guide draught fan, a sound insulation mechanism, a filtering mechanism and an air guide plate. The air guide draught fan used for air blasting is fixedly connected to the center position of the upper end face of the sound insulation mechanism in an embedded manner. By means of the sound insulation and noise reduction FFU draught fan filtering protection mechanism, the sound insulation mechanism is arranged so that during filtering, an external control mechanism can start the air guide draught fan, the draught fan sound insulation cover is arranged on the top of the air guide draught fan, the interior of the draught fan sound insulation cover is arranged to be hollow, the draught fan noise close to the outer portion can be effectively lowered, then the air guide draught fan can guide external air in, the air is evenlydispersed to the upper portion of the filtering mechanism through an air guide cylinder, the upper portion of each set of sound insulation adsorption cotton is in a wave shape, noise can be effectively adsorbed, meanwhile, totally two sets of sound insulation adsorption cotton are arranged, and honeycomb-shaped holes are formed in the sound insulation adsorption cotton and filtering plates, and noise can be further adsorbed.

Description

technical field [0001] The invention relates to the technical field of filter fans, in particular to a sound-proof and noise-reducing FFU fan filter protection mechanism. Background technique [0002] The fan filter unit is an air self-cleaning device, which can be installed on the indoor ceiling or placed on the bracket to optimize the local air. It can also be used for air supply at the end of the clean room. When working, the fan sucks in the air from the top and After being filtered by primary and high-efficiency filters, the filtered clean air is sent out from the air outlet, but the existing fan filter mechanism, the fan has a certain amount of noise when it is running, which is likely to cause sound pollution to the surrounding environment, so there is an urgent need for a sound insulation reducer Noisy FFU fan filter protection mechanism to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to provide a sound-proof...
