[0047] Embodiment
[0048] Referring to Figures 1 to 8 , for the embodiment of the present invention, there is provided
[0049] A ball mill for mixing materials, comprising: a frame 1; a drum 2 rotatably arranged on the frame 1; an inner lining cylinder 3 arranged on the drum 2, the inner lining cylinder 3 rotates with the drum 2, the inner lining cylinder 3 has a mixing cavity 4 for mixing and crushing materials, and a sound insulation gap 5 is formed between the inner lining cylinder 3 and the drum 2; a sound absorption cotton 6 arranged in the sound insulation gap 5.
[0050] In this embodiment, the ball mill for material mixing is a device that can not only mix materials but also crush the materials by the rolling of the steel balls' own weight in the drum 2. However, since the steel balls will generate extremely loud noises when falling with the rotation of the drum 2 and will damage the inner wall of the inner lining cylinder 3, the inner lining cylinder 3 and the drum 2 are provided in this solution. After the inner lining cylinder 3 is damaged by the steel balls, it is convenient to replace. In order to reduce noise, there is a sound-absorbing gap between the inner lining cylinder 3 and the drum 2 of this solution, and sound-absorbing cotton 6 is arranged in the sound-absorbing gap. The sound-absorbing cotton 6 has a plurality of sound-absorbing holes and protrusions, which can have a good sound-absorbing effect on the noise of gravity fall, thereby reducing the noise of the movement of this device and reducing the damage to the eardrums of the operators.
[0051] Furthermore, there are several pieces of sound-absorbing cotton 6. Each of the several pieces of sound-absorbing cotton 6 has a first groove 7 and a first protrusion 8. The first protrusion 8 of one piece of sound-absorbing cotton 6 is used for slidingly arranging in the first groove 7 of another piece of sound-absorbing cotton 6. The several pieces of sound-absorbing cotton 6 are arranged in a circular arrangement end to end in the sound-insulating gap 5.
[0052] In this embodiment, since the steel balls falling with the rotation of the inner lining cylinder 3 in the inner lining cylinder 3 will damage the inner lining cylinder 3 and will also damage the sound-absorbing cotton 6 located in the sound-absorbing gap. When the service life of the sound-absorbing cotton 6 reaches the limit, the sound-absorbing effect will be significantly reduced. However, the uneven process of the steel balls falling may cause local damage to the sound-absorbing cotton 6. In order to reduce the replacement cost of the sound-absorbing cotton 6, the sound-absorbing cotton 6 in this solution is several pieces. The several pieces of sound-absorbing cotton 6 are spliced by the first protrusion 8 and the first groove 7. When a part of the sound-absorbing cotton 6 is damaged, only the damaged part of the sound-absorbing cotton 6 needs to be replaced, reducing the cost of replacing the sound-absorbing cotton 6.
[0053] Furthermore, it also includes: two mounting plates 9 are respectively arranged at both ends of the inner lining cylinder 3. The mounting plates 9 have a first annular groove 10 and a second annular groove 11; there are two first arc plates 12 with a second protrusion 13. The second protrusion 13 is slidingly arranged in the first annular groove 10. The first arc plate 12 has an opening 14, and the width of the opening 14 is greater than the width of the sound-absorbing cotton 6; there are two second arc plates 15 with a third protrusion 28. The third protrusion 28 is slidingly arranged in the second annular groove 11. The width of the second arc plate 15 is greater than the width of the opening 14, and the second arc plate 15 has an avoidance groove 16 for avoiding the first arc plate 12. Mounting holes 17 are arranged on the first arc plate 12 and the second arc plate 15, and the mounting holes 17 are used for connecting the first arc plate 12 and the second arc plate 15 by bolts.
[0054] In this embodiment, since the device can be used for mixing water and solid materials, in order to prevent moisture from flowing into the sound-absorbing cotton 6 and affecting its sound-absorbing effect, mounting plates 9 are provided at both ends of the inner lining cylinder 3. A first annular groove 10 and a second annular groove 11 are provided on the mounting plate 9. The first arc plate 12 and the second arc plate 15 are respectively slidably arranged in the first annular groove 10 and the second annular groove 11. The first arc plate 12 has an opening 14, and the width of the opening 14 is greater than the width of the sound-absorbing cotton 6. The width of the second arc plate 15 is greater than the width of the sound-absorbing cotton 6. The second arc plate 15 has an avoidance groove 16 for avoiding the first arc plate 12. The first arc plate 12 and the second arc plate 15 can complete the sealing of the sound-absorbing gap by sliding in the first annular groove 10 and the second annular groove 11. When replacement is not required, slide the second arc plate 15 to the opening 14 of the first arc plate 12, and fix the first arc plate 12 and the second arc plate 15 through bolts passing through the mounting holes 17 to seal the sound-absorbing gap. When the sound-absorbing plate needs to be replaced, slide the first arc plate 12 and the second arc plate 15, and replace the sound-absorbing cotton 6 through the opening 14 of the first arc plate 12.
[0055] Further, it also includes: two rotating cylinders 18 are provided on the mounting plate 9. The rotating cylinder 18 has a material passing channel 19, and the material passing channel 19 communicates with the mixing cavity 4.

[0056] In this embodiment, there are two rotating cylinders 18. The two rotating cylinders 18 have two material passing channels 19, which are respectively used for feeding and discharging materials. And the rotating cylinder 18 is rotatably arranged on the frame 1 through the bearing seat 20, which can reduce the resistance of the rotation of the rotating cylinder 18, making the rotation of the roller 2 smoother during the rotation process, and having a better effect of mixing and crushing materials.
[0057] Further, it also includes: a spiral blade 21 is arranged in the material passing channel 19 of one rotating cylinder 18, and the spiral blade 21 is used for discharging materials.
[0058] In this embodiment, the spiral blade 21 is arranged in one rotating cylinder 18, which can convey the materials that are evenly mixed and completely crushed in the roller 2 through the spiral blade 21, and has a more continuous operation effect.
[0059] Further, it also includes: two material blocking frames 22 are respectively arranged on the two rotating cylinders 18, and the material blocking frames 22 are used to block the steel balls for crushing materials located in the inner lining cylinder 3.
[0060] In this embodiment, since there are not only materials but also steel balls in the mixing cavity 4, in order to prevent the steel balls from passing through the material passing channel 19, a material blocking frame 22 is provided at the material passing channel 19 of the rotating cylinder 18 in this solution. The material blocking frame 22 can pass materials, but cannot pass the relatively large steel balls, which can avoid the situation of steel balls being mixed in the materials and reduce unnecessary processes.
[0061] Further, it further includes: a driving assembly 23 provided on the frame 1, and the driving assembly 23 is used to drive the roller 2 to rotate.
[0062] In this embodiment, the driving unit 27 provided on the frame 1 can drive the roller 2 to rotate continuously. Through the continuous rotation of the roller 2, the continuous mixing and conveying of the materials can be completed, making this solution have a more continuous and stable effect. The driving device can be gear drive, belt drive, etc.
[0063] Further, the driving assembly 23 includes: a first belt pulley 24 provided on the roller 2; a second belt pulley 25 rotatably provided on the frame 1; a plurality of transmission belts 26 wound around the first belt pulley 24 and the second belt pulley 25; and a driving unit 27 provided on the frame 1, and the driving unit 27 is used to drive the second belt pulley 25 to rotate.
