(1) acoustic hood and isolation booth noise reduction mode.Which floor space is larger, and ventilation and heat is poor, and the operational inspection to equipment, cleaning leakage powder, handling steel ball, Maintenance and Repair bring very big inconvenience.
(2) rubber lining mode.Rubber lining price is higher, and the life-span is shorter, also may affect ball mill efficiency.
Summary of the invention
The purpose of this utility model, is exactly the problems referred to above that exist for prior art, and a kind of combination unit that noise effects ball mill noise good, that do not affect ball mill operation, easy installation and removal is administered of controlling is provided.
For realizing above-mentioned purpose of the present utility model, the technical solution that the combination unit that a kind of ball mill noise of the utility model is administered adopts is:
The combination unit that a kind of ball mill noise of the utility model is administered, it is to constitute by being arranged on the noise reduction plate device on ball mill barrel surface and being arranged in movable high-efficiency gobo around:
Described noise reduction plate device is to be arranged and form along ball mill barrel surface by noise reduction template, noise reduction template by damping rubber layer, curved stainless steel perforated plate, fire prevention nonwoven, baffle blanket, deadening felt, outer cover of steel plate from inside to outside sequential combination form, brace rod is also installed between baffle blanket, deadening felt, on outer cover of steel plate outer ledge, be provided with the flange that connects use, along adopting flange to connect between the adjacent noise reduction template of cylindrical shell circumference;
Described movable high-efficiency gobo is to consist of gobo, holder combination, and gobo consists of plate stainless steel perforated plate, baffle blanket, deadening felt, outer cover of steel plate sequential combination, and gobo is rack-mount, and the bottom of support is provided with universal wheel.Between adjacent two fan gobos, by snap close, connect, convenient fixing and mobile.In actual use, effectively reduce ball mill borne noise.
For increasing noise reduction, in described outer cover of steel plate, spray damping paint, in described outer cover of steel plate, be provided with damping paint, damping paint can be painted on the inner surface of outer cover of steel plate.Between interconnective flange, rubber blanket is set.
Described support adopts triangular supports to be advisable; The quantity of the described noise reduction template along cylindrical shell circumference is 3-6, take 4 as good.
In actual use, noise reduction template, with barrel body rotation, effectively reduces cylindrical shell vibration, reduces cylindrical shell noise transmission.
The beneficial effect of the combination unit that a kind of ball mill noise of the utility model is administered is: because the noise reduction template of cylindrical shell adopts damping, sound absorption, sound insulating material, combine, effectively reduce ball mill barrel noise unofficial biography, reduce Whole Equipment noise; Movable high-efficiency gobo suits measures to local conditions to be arranged in around ball mill, further hinders the route of transmission of noise, reduces noise transmission.Entirety noise reduction can make the ball mill noise in running reduce to 80～85 decibels from 100～110 decibels, reaches national requirements for environmental protection, and has avoided the shortcoming of traditional noise reduction mode; Between each noise reduction template, adopt flange, bolt to connect, easy installation and removal, does not affect ball mill repair and maintenance; Noise reduction template is arranged on ball mill barrel outside, does not affect ball mill efficiency; Efficient gobo is arranged in around ball mill, conveniently moving.
