Abstract
The utility model relates to an additional device of a ball tube mill. A silencing and sound shield cover of the device is composed of a flexible substrate layer, a flexible sound-absorbing layer, and a flexible sound shield layer fixedly connected in sequence. The silencing shield cover is fixed on an outer surface of the whole cylinder body via straps and a packing buckle. The device has the advantages of lightness, less load for a ball mill, simple operation, and convenient maintenance during use. The silencing shield cover of the device is a flexible structure and can ensure the outer surface of the cylinder body of the ball mill to cover in the silencing and sound shield cover for causing silencing and sound shield functions to play. After testing, the noise can be reduced from 10 to 30 decibels.
Description
The utility model relates to a kind of attachment device of ball tube mill.
During the work of existing skeleton symbol ball mill, material and steel ball skill certain proportion are put into simplified, when making low speed rotation under the simplified drive at motor, material is ground under the bump of steel ball.Owing to the continuous bump of thousands of steel balls and material and cylindrical shell, make ball tube mill become " noise source " that produces serious noise, noise is above 100 decibels.Method of sound insulation commonly used at present, a kind of is with the case cover with whole ball mill, though can play the sound insulation and noise reduction effect, but ball mill inside goes wrong and is difficult to observe, huge housing makes the maintain and replace difficulty, also cause the improper ventilation of motor, easily cause motor overheating, produce unsafe factor.Another kind is a housing of making 1/4 half slide structure with iron sheet, and the liner woollen blanket screws down on ball mill barrel again; Its shortcoming is: because the sound insulation housing is the rigidity structure, the own wt of steel construction Hough formula sound insulation shell has increased load on the contrary the ball mill in the running; If be used for adding that by the ball tube mill of bolting abrasionproof liner plate ball mill has 4 to arrange the bolt that is used for the simplified interior abrasionproof liner plate of anchoring that protrudes on simplified, can't carry out sound insulation for the moment and handle, thereby cause soundproof effect extremely low, do not have deadening basically.
The purpose of this utility model is that the noise elimination sound arrester of the ball tube mill that a kind of weight is light, simple to operate when using, the noise elimination soundproof effect is obvious, easy to maintenance is provided.
The technical scheme that realizes the utility model purpose is: this device has simplified, its design feature is: also have noise elimination blimp and strap and packing button, the noise elimination blimp is made of the flexible substrate layer that is fixedly connected sequentially, flexible absorbent treatment and flexible puigging; The noise elimination blimp fixedly covers on the outer surface of whole cylindrical shell by strap and packing button, and the flexible substrate layer of the blimp of wherein eliminating the noise contacts with simplified outer surface, and strap contacts with the flexible puigging of noise elimination blimp.
The flexible substrate layer of above-mentioned noise elimination blimp is a low alkali glass fiber cloth, and flexible absorbent treatment is a mineral wool, and flexible puigging is flame retardant type PVC artificial leather or waterproof cloth.
The packing of said fixing on the noise elimination blimp has multiple tracks, establishes together every 20～40 centimetres.
Consider to make this device also applicable to the ball tube mill by bolting abrasionproof liner plate, this noise elimination sound arrester also is provided with removable cover, and the noise elimination blimp also is provided with bolt hole, and the bolt on the cylindrical shell is located in the bolt hole of noise elimination blimp; One side of removable cover is fixedlyed connected with the noise elimination blimp, and opposite side is fixed with junction button, is interlockingly connected by junction button and noise elimination blimp.
The utlity model has positive effect: the noise elimination blimp of (1) this device is a flexible structure, guarantees that the simplified outer surface of ball mill all covers within the noise elimination blimp, thereby the noise elimination deadening of noise elimination blimp can be given full play to.Reduce by 10～30 decibels before the effect of eliminating the noise after tested is comparable.What (2) use because of this device is the lightweight material structure, so do not increase the load of ball mill in the running substantially; Adopt strap that the noise elimination blimp is tightened on simplified, can guarantee to be in operation can not come off.(3) for the ball tube mill by bolting abrasionproof liner plate, this device is provided with movable cover structure, also can play the soundproof effect of eliminating the noise preferably.(4) this device is used for that ball tube mill is easy for installation, maintenance is also convenient.This device also has good insulation effect, for energy savings, reduction environment temperature significant effect is arranged all.
Drawing of the present utility model is described as follows:
Fig. 1 is the schematic diagram of the utility model noise elimination blimp three-decker.
Fig. 2 is a kind of structural representation of this device.Abrasionproof liner plate in its middle cylinder body is connected with the non-bolt type of being connected to of cylindrical shell.
Fig. 3 is a kind of structural representation of this device.Abrasionproof liner plate in its middle cylinder body is connected with the bolt type that is connected to of cylindrical shell.
The utility model will be further described below in conjunction with drawings and Examples.
Embodiment 1,
See Fig. 1, noise elimination blimp 2 is by flexible substrate layer 21, flexible absorbent treatment 22 and the flexible puigging 23 of fixed bonding constitute successively; The flexible substrate layer 21 of noise elimination blimp 2 is resistant to elevated temperatures low alkali glass fiber cloth, and flexible absorbent treatment 22 is a mineral wool, and mineral wool can be rock wool, mineral wool or aluminosilicate fiber cotton, and flexible puigging 23 is flame retardant type PVC artificial leather or waterproof cloth.
See Fig. 2, abrasionproof liner plate 8 in the cylindrical shell 1 of ball tube mill is connected with the non-bolt type of being connected to of cylindrical shell, also be that forms such as the abrasionproof liner plate can weld are fixed on the inwall of cylindrical shell, noise elimination blimp 2 fixedly covers on the outer surface of whole cylindrical shell 1 by strap 3 and packing button 4, the flexible substrate layer 21 of blimp 2 of wherein eliminating the noise contacts with the outer surface of cylindrical shell 1, and strap 3 contacts with the flexible puigging 23 of noise elimination blimp 2.The strap 3 that is fixed on the noise elimination blimp 2 has multiple tracks, establishes together every about 30 centimetres.
See Fig. 3, difference from Example 1 is: the abrasionproof liner plate 8 in the cylindrical shell 1 of the ball tube mill of present embodiment is connected with the bolt type that is connected to of cylindrical shell, the bolt 11 that is used for abrasionproof liner plate 8 in the anchoring cylindrical shell that has 4 rows to protrude on the cylindrical shell.The corresponding 4 block of material structures removable cover 6 identical that be provided with of noise elimination sound arrester with the three-decker of noise elimination blimp 2, the noise elimination blimp 2 corresponding 4 row's bolts hole 24 that are provided with, each bolt 11 on the cylindrical shell 1 is located in the corresponding bolts hole 24 of noise elimination blimp 2; After each strap 3 is accomplished fluently, a side and the noise elimination blimp 2 of each removable cover 6 fixedly sewed up, opposite side fixedly sews up junction button 7, is interlockingly connected by junction button 7 and hasp on the noise elimination blimp 2.
