Description
Technical field
The utility model relates to noise reduction fields.
Background technique
Flyash is one of primary solids waste of coal-burning power plant, with the development of science and technology, flyash is as a kind of coagulation
One of an important factor for native admixture is widely used in production, and fineness of pulverized-coal ash is influence concrete strength, is using
It generally requires its is levigate, however during fine-ground fly-ash, makes an uproar since the operating bring of ball mill is huge in the process
Sound not only results in very big noise pollution, while may be to the artificial harm in terms of body and mind.Therefore, it is necessary to ball milling
The noise of machine carries out control reduction.
Utility model content
The technical problem to be solved by the utility model is to how to reduce the influence of the Noise upon Environment of ball mill.
The technical scheme adopted by the utility model is a kind of power plant's waste material noise reduction grinding device, including tip upside down on ball milling
Blimp (4) on machine, there is thermovent (5) and soundproof door (6) on blimp (4), and thermovent (5) connects sound insulation cylinder, sound insulation
It is viscous by sound insulating seal glue (10) by sound-absorbing material (1), the first sheet metal (2), damping material (3) respectively from inside to outside to cover (4)
It connects, sound insulation cylinder is thin by the second sheet metal (7), the first deadening felt (8), the second deadening felt (9), third respectively from inside to outside
Steel plate (11) is bonded by sound insulating seal glue (10).
As a kind of preferred embodiment: sound-absorbing material is 24kg/m by the density of 30mm thickness3The first block of glass wool and 30mm
Thick density is 32kg/m3The second block of glass wool interval be formed by stacking.
As a kind of preferred embodiment: the first sheet metal, the second sheet metal, third sheet metal thickness be all 30mm.
As a kind of preferred embodiment: damping material is damping-constraining coating of the fissipation factor 0.8 with a thickness of 6cm.
As a kind of preferred embodiment: thermovent (5) is connect with sound insulation cylinder by flange (12).
The beneficial effects of the utility model are: the utility model effectively reduces the influence of the Noise upon Environment of ball mill.

Specific embodiment
In order to lower the huge noise that ball mill generates during operation, the utility model provides a kind of effective drop
It makes an uproar device, main includes the blimp 4 tipped upside down on ball mill and the sound insulation cylinder connecting with the thermovent 5 of blimp 4.
Blimp 4: blimp 4 is made by sound-absorbing material, the first sheet metal, damping material respectively from inside to outside.It inhales
Sound material is mineral wool, is invested on the inside of sheet metal, in order to reach better sound absorbing performance, is come using the mineral wool of different bulk density
It is used cooperatively, therefore the density of the utility model block of glass wool for the use of the density of 30mm thickness being 24kg/m3 and 30mm thickness is
The mineral wool interval of 32kg/m3 is superimposed 2 layers and invests on the inside of the first sheet metal, possesses more good sound absorbing performance, can efficiently inhale
The noise that ball mill generates at work is received, sound insulation and noise reduction effect is reached.First sheet metal 2 is the important portion for forming blimp 4
Part.In view of the convenience of ball milling machine check and maintenance, while blimp 4 should possess good soundproof effect, the first sheet metal 2
Structure should not be excessively heavy, therefore the present embodiment uses the first sheet metal 2 of 30mm, and the noise that can be generated to ball mill plays
Certain barrier action.Soundproof door is installed in front of blimp 4, facilitates inspection and maintenance work of the staff to ball mill, every
Sound door is using the soundproof door bought in the market.There are thermovent 5, diameter is about 200mm at blimp rear, at thermovent even every
Sound cylinder, convenient for the amount of heat discharge for generating ball mill during the work time.Damping material uses damping paint, this implementation
Example selects damping-constraining coating, and internal loss coefficient is larger, and fissipation factor is 0.8 or so, and with a thickness of 60mm, it is uniformly applied to
On the outside of sheet metal, it can not only achieve the effect that vibration damping, moreover it is possible to reduce mechanicalness noise, enable the work of ball mill more stability and high efficiency
Make, prolongs its service life.
Sound insulation cylinder: sound insulation cylinder main body uses bilayer 30mm sheet metal, and for the second sheet metal as interior steel liner plate, third is thin
Steel plate is cylinder body outer wall, two layers of Efficient Damping deadening felt (market purchase) is laid between two sheet metals, the deadening felt is not only easy
In bending, facilitate construction, ball mill barrel inner wall can be invested very well, and soundproof effect is ideal, can effectively completely cut off ball mill
The noise generated when work.
On blimp between mineral wool and the first sheet metal 2, between the first sheet metal 2 and damping-constraining coating 3, sound insulation cylinder
On body between the second sheet metal 7 and the first deadening felt 8, between the first deadening felt 8 and the second deadening felt 9, the second deadening felt 9 and
The bonding of sound insulating seal glue 10 is all made of between three sheet metals 11, sound insulating seal glue 10 is bought using market, and free from extraneous odour will not be to ring
Border pollutes, and can be effectively sealed to gap everywhere, and its sound insulation value is very significant, has anti-aging well
Ability is a kind of good sound insulaton material.Thermovent 5 is connect with the connection of sound insulation cylinder using flange 12, convenient for disassembly and assembly,
Gap is bonded using sound insulating seal glue 10 therebetween, and sealing effect is good, can more preferably realize noise reduction.Soundproof door 6 uses and singly opens soundproof door,
The unlatching for being not only convenient for ball mill uses, and can also reach better sound insulating seal effect.
