The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1～shown in Figure 11, ball mill of the present utility model, comprise cylindrical shell 1, it is vertically arranged with multi-turn bolt hole 4 cylindrical shell 1 upper edge, one section of described cylindrical shell 1 is provided with manhole 8 and the cover plate for manhole 10 that protrudes from the cylindrical shell rotary surface, and at described that section cylindrical shell arranged outside manhole outer cover 11 that is provided with manhole 8, described manhole outer cover 11 is slidingly connected with respect to cylindrical shell 1,, the bolt on this section cylindrical shell is carried out terminal operation with convenient; In order to completely cut off the noise that the remainder cylindrical shell spreads out of from bolt hole 4 positions, remainder cylindrical shell arranged outside annular outer cover 12, annular outer cover 12 is provided with the handle hole 15 of position corresponding to each bolt hole 4, annular outer cover 12 is rotationally connected with respect to cylindrical shell 1, when needing fastening bolt, rotating annular outer cover 12 is emerging in the handle hole 15 bolt on its cylindrical shell 1, carry out fastening operation, after fastening the finishing, low-angle rotates corresponding the staggering of position that annular outer cover 12 makes its handle hole 15 and each bolt hole 4, can further cut off the noise transfer at bolt hole 4 places; Between described manhole outer cover 11 and the annular outer cover 12 lap is arranged, avoid noise to spread out of from the gap between manhole outer cover 11 and the annular outer cover 12, the annular outer cover 12 of lap is in manhole outer cover 11, to make things convenient for along cylindrical shell longitudinal sliding motion manhole outer cover 11, carry out the bolted operation, described manhole outer cover 11 and annular outer cover 12 have the vacuum lumen structure, can play the effect of isolated most of noise, generally, the inner chamber vacuum of manhole outer cover 11 and annular outer cover 12 is 10
-1～10
-3Pa can make the ball mill noise in the running reduce to 70～80 decibels from 110 decibels, and very significantly noise reduction is arranged, and can no longer join for ball mill of the present utility model and build the sound insulation room, has reduced ball mill floor space is installed, and has saved cost.
As shown in Figure 6, described to have the vacuum lumen structure be following structure: described structure comprises lamina rara externa 19, inner plating 16 and be filled in lamina rara externa 19 and inner plating 16 between hollow sheeting 18, also be arranged at intervals with reinforcement 17 between lamina rara externa 19 and the inner plating 16, spacing between the cross sectional dimensions of reinforcement 17 and lamina rara externa 19 and the inner plating 16 is complementary, this structure both had been convenient to utilize current material to realize hollow space is vacuumized, and has certain intensity, not yielding after vacuumizing, described lamina rara externa 19 generally can adopt sheet metal or similar material with inner plating 16, and reinforcement 17 can adopt steel wire or similar material, and hollow sheeting 18 can adopt sunlight board.
Between cylindrical shell 1 and described manhole outer cover 11 and annular outer cover 12, be provided with the blimp 2 adaptive with cylindrical shell rotary surface profile phase, the outer hole 9 adaptive with manhole 8 arranged on the described blimp 2, sound insulation chamber 3 for vacuumizing between blimp 2 and the cylindrical shell 1, the sound insulation chamber 3 of this specification alleged " vacuumizing ", the vacuum that is meant sound insulation chamber 3 is 10
-1～10
-3Pa utilizes blimp 2 to intercept the transmission of most of noise in advance, thereby when carrying out the bolted operation, also lower noise can be arranged, the working environment when improving this kind operation.
For reducing cost, it is steel plate, iron sheet, copper sheet, aluminium skin or the Teflon etc. of thickness below 2mm that the material of making blimp 2 should adopt slim, thus, then the bolt on the cylindrical shell 1 can not directly be screwed on the blimp 2, therefore, be preferably in cylindrical shell 1 outer wall and be provided with the annular support wall 6 corresponding with each bolt hole 4, described each annular support wall 6 is connected for the part wall in sound insulation chamber 3 and with blimp 2 simultaneously, and the bolt on the cylindrical shell 1 then tightens on the annular support wall 6.
When the material of making blimp 2 adopts thin material, vacuum pumping is carried out in sound insulation chamber 3, must bring the distortion of blimp 2, for preventing that blimp 2 excessive distortion are attached on the cylindrical shell 1, weaken noise reduction, preferably also between the annular support wall 6 of described cylindrical shell 1 outer wall, be connected with liner plate 5 by support column 7, liner plate 5 supports the inwall of blimp 2, more much smaller than directly attaching to the noise that is delivered on the blimp 2 on the cylindrical shell 1 after all by the noise that support column 7 is delivered on the blimp 2 every blimp 2, thus the noise reduction of assurance blimp 2.
