Method used

As shown in Figure 6, described structure with vacuum cavity is following structure: described structure comprises outer layer plate 19, inner layer plate 16 and fills in the hollow plate 18 between outer layer plate 19 and inner layer plate 16 , between the outer layer plate 19 and the inner layer plate 16, reinforcing ribs 17 are arranged at intervals, the cross-sectional size of the reinforcing ribs 17 matches the distance between the outer layer plate 19 and the inner layer plate 16, this structure is convenient to use The existing material realizes vacuuming the hollow part, and has a certain strength, and is not easily deformed after vacuuming. The outer layer plate 19 and the inner layer plate 16 can generally use thin steel plates or similar materials, and the reinforcing ribs 17 can use steel wires or similar materials, the hollow plate 18 can be a solar panel.
As shown in Figures 1 to 11, the ball mill of the present invention includes a cylinder 1, and the cylinder 1 is provided with a plurality of circles of bolt holes 4 along its longitudinal direction, and a section of the cylinder 1 is provided with a protruding The manhole 8 and the manhole cover plate 10 on the rotating surface of the cylinder are provided with a manhole cover 11 outside the section of the cylinder where the manhole 8 is provided, and the manhole cover 11 is slidably connected to the cylinder 1, In order to facilitate the fastening operation of the bolts on this section of the cylinder; in order to isolate the noise from the rest of the cylinder from the position of the bolt hole 4, an annular outer cover 12 is arranged on the outside of the remaining part of the cylinder, and the annular outer cover 12 is provided with a position corresponding to The operation hole 15 of each bolt hole 4 is connected with the annular outer cover 12 in rotation relative to the cylinder body 1. When the bolts need to be tightened, the bolt on the cylinder body 1 is exposed in the operation hole 15 by rotati...

Abstract

The invention discloses a ball mill with a function of reducing running noises, which is characterized in that a ball mill body comprises a cylinder, and the cylinder is provided with a plurality of circles of bolt holes along the longitudinal direction of the cylinder; one section of the cylinder is provided with a manhole and a manhole plate which are protruded from the rotating surface of the cylinder, the outer side of the section of the cylinder provided with the manhole is provided with a manhole shield, and the manhole shield is movably connected relative to the cylinder; the outer side of the rest of the cylinder is provided with an annular shield, the annular shield is provided with operating holes, the positions of the operating holes are corresponding to those of the bolt holes, and the annular shield is rotatablely connected relative to the cylinder; an overlapping part exists between the manhole shield and the annular shield, and the annular shield of the overlapping part is covered in the manhole shield; the manhole shield and the annular shield are respectively provided with a vacuum cavity structure; and a layer of sound-proof shield packed on the rotating surface of the cylinder is arranged among the manhole shield, the annular shield and the cylinder, by which the noise of the ball mill can be reduced to 30 to 40 decibels. The invention has the advantages of reducing cost and occupied land area and improving the operating environment, therefore, the invention is especially suitable for horizontal ball mill.

Example Embodiment

[0031] Example :
[0032] Such as Figure 1~Figure 11 As shown, the cylinder 1 of the ball mill is provided with an annular support wall 6 corresponding to the position of each bolt hole 4, and a sound insulation cover 2 that matches the contour of the cylinder's revolving surface is provided with a plurality of matching annular support walls 6. Each hole wall is connected with each annular support wall 6, thereby forming a vacuumable sound insulation cavity 3 between the soundproof cover 2 and the cylinder 1, and a support column 7 is arranged between the annular support walls 6 and the support column 7 is The connecting lining board 5 supports the soundproof cover 2; on the cylinder 1, two upper and lower manholes 8 protruding from the rotating surface of the cylinder are respectively provided near the feeding end 13 and the discharging end 14, corresponding to the manhole 8 Two manhole covers 11 are provided at the position of, and the manhole covers 11 are slidably connected to the soundproof cover 2, the outer side of the soundproof cover 2 on the middle part of the cylinder is provided with a ring cover 12, and the ring cover 12 is rotatably connected to the soundproof cover 2, There is an overlapping part between the manhole cover 11 and the annular cover 12, and the overlapping part of the annular cover 12 is inside the manhole cover 11. As a result, a movable cover is provided outside the soundproof cover 2 The combination of the hole cover 11 and the ring cover 12 does not affect the bolt tightening operation of the ball mill after a period of operation, and can further reduce noise. The use of the cover can further reduce the noise to 30-40 decibels.
