Abstract

A kind of ball mill sound insulation and noise reduction device, be made up of rolling element (1), inner core (2) and urceolus (3), there is shell (6) in the outer setting of urceolus (3), and between urceolus (3) and shell (6), be disposed with baffle blanket (4) and vacuum sound insulation layer (5).At ball mill sound arrester of the present utility model, there is shell in the outer setting at urceolus, and between urceolus and shell, be disposed with baffle blanket and vacuum sound insulation layer; Scribble damping paint at the inwall of described shell simultaneously, significantly reduce the noise produced in ball mill running, and then efficiently solve the serious problem of noise pollution.

Description

A kind of ball mill sound insulation and noise reduction device

Technical field

The utility model relates to ball mill field, is specially a kind of ball mill sound insulation and noise reduction device.

Background technology

After ball mill is material fragmentation, carry out the key equipment pulverized again, the production industry such as extensive use and non-ferrous metal ore, the steel ball of inside promotes by centrifugal force when existing ball mill general rotates, and is pulverized material by the interaction between steel ball and material.But the hoisting power of centrifugal force is limited, before steel ball does not also reach top, will fall because of Action of Gravity Field, maximum common speed cannot be reached, simultaneously because steel ball is to the enormous impact power of ball mill barrel and frictional force, ball mill needs continuous rotation down in working order, so ball mill needs the weight of load very large under whole duty, the noise pollution of generation is also very serious.

Utility model content

In order to solve the noise pollution serious problems occurred in ball mill operation process, the utility model provides a kind of ball mill sound insulation and noise reduction device.

To achieve these goals, the technical problem that the utility model solves realizes by the following technical solutions: a kind of ball mill sound insulation and noise reduction device, be made up of rolling element, inner core and urceolus, there is shell in the outer setting of urceolus, and between urceolus and shell, be disposed with baffle blanket and vacuum sound insulation layer.

Further, damping paint is scribbled at the inwall of described shell.

beneficial effect

At ball mill sound arrester of the present utility model, there is shell in the outer setting at urceolus, and between urceolus and shell, be disposed with baffle blanket and vacuum sound insulation layer; Scribble damping paint at the inwall of described shell simultaneously, significantly reduce the noise produced in ball mill running, and then efficiently solve the serious problem of noise pollution.

Detailed description of the invention

In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with accompanying drawing, set forth the utility model further.

The schematic diagram of the utility model structure as shown in Figure 1, the A-A sectional view of the utility model structure shown in Fig. 2.A kind of ball mill sound insulation and noise reduction device; be made up of rolling element 1, inner core 2 and urceolus 3; the shell 6 for the protection of ball mill parts is had in the outer setting of urceolus 3; and between urceolus 3 and shell 6, be disposed with baffle blanket 4 and vacuum sound insulation layer 5; baffle blanket 4 can absorb the noise that ball mill running produces; enter in vacuum sound insulation layer 5 after part is not penetrated baffle blanket 4 by the noise that baffle blanket 4 absorbs, under the effect of vacuum sound insulation layer 5, prevent this part noise to pass to ball mill job shop.

The damping paint of vibration and the noise transmission that can suppress shell 6 and whole ball mill is scribbled at the inwall of described shell 6.

More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
