Abstract
The utility model relates to a noise isolation cover with multilayered structure of a ball grinder. Noise isolation covers with multilayered structure of a barrel and an end cap are directly arranged on the ball grinder, and rotate together with the ball grinder to mainly control the noise produced by the barrel. Multilayered noise isolation and absorption and a damp are adopted, a steel plate of a noise isolation layer is made into the shape of a cylinder which has the same core with the barrel, the length of the barrel and the arrangement of screw bolts arranged on the barrel are divided into a plurality of parts which are assembled at installing time to wrap the whole barrel, thereby the sealed noise isolation cover with multilayered structure is formed. The utility model has the advantages of simple structure, convenient mounting, usage and maintenance, perfect noise prevention and elimination effect, slight investment, instant effect and perfect effect.
Description
Technical field: the utility model relates to the noise abatement technology, particularly relates to a kind of steel ball mill sandwich construction sound insulation cover.
Background technology: well-known, ball mill is to be widely used in electric power, indispensable production utensil in the production industries such as cement, when ball mill is being produced in the operation process, mill mutually between wear body that it is inner and the material and clash into the bigger noise of generation, noise level can be up to 110-120dB (A), this public hazards serious harm people's physical and mental health and social living environment, and existing ball mill manufacturer is for sound insulation and noise reducing, promptly add a bigger acoustic hood and reduce noise in the rotating machinery outside, the cost height but its structure is huge, the equipment of being not easy to is checked and is keeped in repair, cause damage easily, be difficult to apply, simultaneously because its work under bad environment, the leak outside dust that produces of equipment is adsorbed in the sound-absorbing material of acoustic hood and has also reduced acoustically effective.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned weak point and design a kind of ball mill sandwich construction sound insulation cover, and it can reduce the sound source noise effectively and solve noise problem with the control noise transmission.
The utility model is to realize like this.The cylindrical shell that makes is directly installed on the ball mill with the sound insulation cover of the sandwich construction of end cap rotates with ball mill.It mainly is the noise that cylindrical shell sound insulation and noise reducing emphasis control cylindrical shell sends.It adopts multilayer sound insulation, sound absorption and damping way of combining to come isolating cylinder bulk noise unofficial biography, sandwich construction sound insulation cover promptly is installed in the outside of cylindrical shell, sound insulating layer on the cylindrical shell adopts the sheet metal of 1.5-5nm to make, the sound insulating layer steel plate is made and the cylindrical shape of cylindrical shell with core, the layout of bolt is divided into several sections on the length of cylindrical shell and the cylindrical shell, carry out assembly unit when mounted again, whole cylindrical shell is wrapped up, form all-sealed structure.Promptly cylindrical shell (1) internal layer is provided with internal layer sound insulation steel plate (2), is connected and fixed with outer sound insulating layer steel plate (3) by top jar ring (4), annular gusset (5).Two ends connect end cover of ball mill (22).
Sandwich construction sound insulation cover is to be installed on the cylindrical shell (1), its structure top layer is the table damping layer, sound insulating layer outside in the table damping layer, being provided with, be provided with outer flame-retardant layer in the outer sound insulating layer, be provided with absorbent treatment in the outer flame-retardant layer, be provided with middle damping layer in the absorbent treatment, establish middle sound insulating layer in the middle damping layer, be provided with interior flame-retardant layer in the middle sound insulating layer, be provided with interior absorbent treatment in the interior flame-retardant layer.Be provided with the internal damping layer in the interior absorbent treatment, internal damping layer and cylindrical shell join, and cylindrical shell (1) internal layer links to each other with wear-resisting lining tile, is installed on the lining tile set bolt in cylindrical shell, fix by the riveting plate; Lining tile set bolt one end is provided with the bolt lid plate with in the bolt box that fixes in the cylindrical shell on the bolt box, be provided with sealing as leather packing at bolt box and cover plate contact position.
Description of drawings: Fig. 1: for the utility model sound insulation is applied mechanically to schematic diagram;
Fig. 2: be the axial cut-away view of the utility model sound insulation cover;
Fig. 3: be the utility model sound insulation cover internal structure schematic diagram.
Accompanying drawing sign: cylindrical shell (1), internal layer sound insulation steel plate (2), sound insulation steel plate (3), top jar ring (4), annular gusset (5), bolt cover plate (6), bolt box (7), table damping layer (8), outer sound insulating layer (9), outer flame-retardant layer (10), absorbent treatment (11), middle damping layer (12), middle sound insulating layer (13), interior flame-retardant layer (14), interior absorbent treatment (15), internal damping layer (16), wear-resisting lining tile (17), cover plate set bolt (18), sealed rubber pad (19), riveting plate (20), lining tile set bolt (21), end cover of ball mill (22).
The specific embodiment: ball mill sandwich construction sound insulation cover of the present utility model, its cylindrical shell (1) is gone up sound insulating layer and is adopted the sheet metal of 1.5-5mm to make and the cylindrical shape of cylindrical shell with core, barrel jacket is to being divided into 6 circular segment along drum shaft, each ring-type is divided into 4 along cylindrical shell, totally 24, the sound insulation unit, effectively overcome the complex structure of 56 cell blocks of former sound insulation cover, easily loosening, the defective of leakiness sound, the sound insulation cover is the different two-layer sound insulation steel plate of thickness, interlayer is the cotton two sound insulating structures formed of the density two-layer centrifugal glass different with thickness in the middle of it, defening effect is good, use the big ZnOw of loss factor and strengthen high temperature resistant damping material, damping vibration attenuation is effective, rotates with cylindrical shell at the outside sound insulation cover of installing of cylindrical shell, the sound insulation of employing multilayer, the double-decker of multilayer sound absorption and multilayer damping, its structure top layer is heatproof damping layer (8), twines the glass mask of thickness 4-5mm on damping layer.Sound insulating layer (9) outside being provided with in table damping layer (8) is the steel plate of 2-3mm with thickness, is provided with outer flame-retardant layer (10) in the sound insulating layer (9) outside, adopts the fire proofing of 2-3mm; Establish absorbent treatment (11) in the flame-retardant layer (10) outside, employing thickness is that 30mm, unit weight are 40kg/m
3The cotton felt of ultra-fine glass, in absorbent treatment (11), be provided with middle damping layer (12), adopt thickness 4-5mm to twine the glass mask, in middle damping layer (12), establish middle sound insulating layer (13), establish interior flame-retardant layer (14) in the middle sound insulating layer (13), establish interior absorbent treatment (15) in the interior flame-retardant layer (14), establish internal damping layer (16) in the interior absorbent treatment (15).For ease of installing along drum shaft to going up the welding sound insulation steel plate radial location piece steel plate of guaranteeing to insulate against sound at annular gusset (5) and be installed on the same face of cylinder every the wide thick annular gusset (5) of one 4-8mm that installs additional of 1-1.5 rice, for ease of lining tile bolt maintenance on the cylindrical shell, add bolt box (7) and bolt cover plate (6) at cylindrical shell (1) bolt place, install one deck sealed rubber pad (19) additional in cover plate (6) and bolt box (7) junction.
