Abstract
The utility model discloses a noise-reducing soundproof box for a fan, and the noise-reducing soundproof is composed of a base, a box plate frame and a box plate. The noise-reducing soundproof box is characterized in that an air inlet and an air outlet are formed on the box plate corresponding to the air inlet and the air outlet of the fan respectively; the box plate is a multilayer composite structure, the outer side of the box plate is a steel plate, and the inner side of the box plate is a microporous plate; a damping layer is arranged on the surface of the microporous plate; a sound-absorbing material is filled between the microporous plate and the steel plate at the outer side; and the base is assembled and connected with the box plate via the box plate frame. The damping material is asphalt asbestos wool having a thickness of 5-7 mm; the microporous plate is a steel plate having a thickness of 2-3 mm, the opening aperture is 0.8-1.2 mm, and the opening rate is 25%; and the sound-absorbing material is extra-fine glass wool or silencing wool having a thickness of 40-60 mm. The noise-reducing soundproof box disclosed by the utility model is simple in structure and obvious in medium-high frequency noise-reducing effect; and a fan unit is assembled in a box body and prevented from wind and rain, thus being prolonged in service life.
Description
Technical field
The utility model belongs to fan manufacturing technology field, is specifically related to a kind of blower fan noise reduction sound proof box.
Background technique
Noise is many-sided to the harm of body and mind, and blower fan is one of many industrial and mining enterprise visual plant, also is one of numerous industrial and mining enterprise pollution source of noise.Adopting acoustic hood or sound proof box is a method the most simple, it is closed the larger device of noise, selecting suitable acoustic hood or sound proof box structure and adopting has efficient sound insulation medium, just can effectively intercept noise and outwards propagate, and noise reduction is on the impact of environment.
Summary of the invention
The utility model provides a kind of blower fan noise reduction sound proof box, and it can effectively isolate the high-frequency noises of the equipment such as blower fan.
The utility model is comprised of base, boxboard framework, boxboard, it is characterized in that establishing respectively intake grill and exhaust outlet on the boxboard of corresponding blower fan inlets and putlets of ventilation, boxboard is multi-layer compound structure, the outside is steel plate, the inboard is many microwell plates, damping layer is established on many microwell plates surface, filling sound-absorbing material between many microwell plates and outside steel plate, and base, boxboard link by the assembling of boxboard framework.
Its material of described damping layer is the pitch asbestos wool, thickness 5～7mm.
Described many microwell plates are 2～3mm Plate Steel, and perforate aperture 0.8～1.2mm, percent opening are 25%.
Described sound-absorbing material is super glass wool or silencing cotton, and filling thickness is 40～60mm.
Get 2～3mm Plate Steel and closely paste pitch asbestos wool damping layer, then punching becomes flanging behind many microwell plates, assembling boxboard framework, and then the filling sound-absorbing material covers outside steel plate.Establish intake grill and exhaust outlet on the boxboard of corresponding blower fan inlets and putlets of ventilation position.Be assemblied on the base by the boxboard framework after all boxboard completes, the blower fan unit is assemblied in the casing.
The beneficial effects of the utility model are: simple in structure, medium-high frequency noise noise reduction is obvious, and the blower fan unit is assemblied in the casing, can prevent wind and weather, prolongs blower fan unit working life.
