Description
Technical field
The utility model relates to a kind of noise elimination noise reduction equipment, particularly about a kind of detachable acoustical insulation sound-deadening cover that can isolate strong noise equipment.
Background technique
In the workshop of more existing enterprises, often have some strong noise equipment that the acoustical insulation sound-deadening device is not set, noise considerably beyond NBS, also has sandblasting machine, pump etc. up to 115dB (A) when moving such as molybdenum spraying machine, also all is strong noise equipment.And,, should strictly control industrial enterprise's noise for workers ' health along with the development of society and the issuing and implementation of " People's Republic of China's law on prevention and cure of occupational disease ", create a working environment and a condition that meets national occupational health standard and hygienic requirements to the workman.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, strong noise source noise insulation factor is not less than dismountable acoustical insulation sound-deadening cover of 25dB (A).
For achieving the above object, the utility model is taked following technological scheme: a kind of dismountable acoustical insulation sound-deadening cover, it is characterized in that: it comprises that one has into, the cover body of exhaust port, described cover body is provided with an operation door, the section ecto-entad of described cover body is followed successively by steel plate, sound absorption is cotton, covering fabric, metal perforated plate, described steel plate inboard is coated with damping layer, be provided with support frame between described steel plate and the described orifice plate, described sound absorption cotton is arranged between the described support frame, the inboard air intake silencing apparatus that connects of described cover body intake grill, the inboard air bells exhauster that connects of described exhaust port, the described exhaust port outside connects a silencing apparatus by a bend muffler, and described cover body removably is assembled on the pedestal of noise source equipment outside.
Described cover body assembling joint is set to tongue and groove and adds the Stamping Steel Ribbon sealing.
Described cover body is provided with a viewing window.
Described cover body is provided with an access door.
The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to be provided with a cover body, therefore the strong noise source can be isolated in the cover body, form by steel plate, damping layer, sound absorption cotton, covering fabric, metal perforated plate owing to cover body itself simultaneously, therefore can stop noise to external diffusion, absorption of noise in cover body.2, the utility model because on cover body, be provided with into, exhaust port, and advancing, be provided with silencing apparatus on the exhaust port, therefore both can not influence the normal ventilation and heat of equipment, can not influence the acoustical insulation sound-deadening effect of cover body again.3, therefore the utility model can carry out machining operation in the cover body outside owing to be provided with operation door, viewing window, access door etc., and regular maintenance can pass in and out by access door, can easily cover body be disassembled during overhaul, and is very easy to use.The utility model is simple in structure, and the noise reduction volume is not less than 25dB (A), can improve workman's operating conditions greatly, has reduced the injury of noise on human body, and it can be widely used in the noise abatement of strong noise equipment such as molybdenum spraying machine, sandblasting machine, pump.
