Description

TECHNICAL FIELD

[0001] The application relates to the technical field of ball milling, and particularly relates to a ball milling device. BACKGROUND

[0002] The ball mill is a key equipment for grinding materials. The ball mill is widely applied to the production of cement, silicate products, new building materials, refractory materials, chemical fertilizers, black and non-ferrous metal dressing and glass ceramics, and is suitable for dry or wet grinding of various ores and other grindable materials. The ball mill is widely used in dressing, building materials and chemical industries.

[0003] The authorized announcement No. CN219723088U discloses a ball mill facilitating discharging. The ball mill facilitates discharging. The dust falling discharging pipeline is arranged, the discharging length of the discharging pipeline is prolonged, and dust raising is reduced. The screen in the discharging pipeline is arranged outside, and the screen is more convenient to clean. When the screen is cleaned, the large particle minerals on the surface of the screen are pushed into the blockage crushing groove at the rear through the blockage cleaning structure on the surface of the screen. When the blockage crushing groove is accommodated to about half of the volume, the blockage crushing mechanism is buckled, the large particle minerals collected are crushed by extrusion, and the treatment requirement is met. The method is more convenient to operate, and the blocked large particle minerals can be directly treated and recycled.

[0040] The working principle of the present invention is as follows: the material to be ground is put into the drum 3 through the feed port 4, a certain number of steel balls are arranged in the drum 3 as grinding media, the motor of the rotating rod 8 is started, the rotation of the rotating rod 8 drives the driving gear 9 to rotate, the rotation of the driving gear 9 drives the rotating gear 5 and the drum 3 to rotate, the rotation of the drum 3 will drive the steel balls and the material to move inside it, the steel balls and the material will collide and rub against each other during the movement so that the material is broken until it is ground into powder, the processed material is discharged through the discharge port 10, and the material first falls into the first filter frame 62, at this time the rotating shaft 66 is rotated, the rotation of the rotating shaft 66 drives the rotating plate 67 to rotate, thereby driving the deflection rod 68 to rotate, the rotation of the deflection rod 68 will drive the first filter frame 62 to shake laterally, A plurality of connecting blocks 64 are fixedly provided on both sides of the first filter frame 62 and the second filter frame 63, and the connecting blocks 64 are hingedly connected by connecting plates 65, so that the first filter frame 62 will swing back and forth above the second filter frame 63, so that the material swings back and forth in the first filter frame 62 to accelerate the screening of the material, and the powdered material passes through the first filter frame 62 and falls into the second filter frame 63 below to be filtered again, and the large particles remain in the first filter frame 62, and the material falling into the second filter frame 63 is screened again, and the material finally falling into the fixed frame 61 is powdered material. In addition, the rotation of the rotating shaft 66 drives the second belt 17 and the support rod 15 to rotate, and the rotation of the support rod 15 drives the first belt 16 to rotate, and the first belt The rotation of 16 drives the limit block 18 and the moving frame 19 to move. When the limit block 18 and the moving frame 19 move from the support rod 15 on one side to the support rod 15 on the other side along the first belt 16, the limit block 18 and the moving frame 19 remain stationary. When the first belt 16 drives the limit block 18 and the moving frame 19 to return, the limit block 18 will move downward along the moving frame 19 under the drive of the first belt 16. Then, when the first belt 16 drives the limit block 18 and the moving frame 19 to return to the initial position, the limit block 18 will move upward along the moving frame 19 again, that is, the first belt 16 will drive the moving frame 19 to complete the horizontal reciprocating movement, and the horizontal reciprocating movement of the moving frame 19 will drive the positioning block 20 to reciprocate along the horizontal groove 141, and the positioning block 20 will move back and forth along the horizontal groove 141. 0's movement will drive the vertical plate 11 to move back and forth horizontally so that the push plate 13 can level the surface of the material accumulated in the fixed frame 61. The push plate 13 can level the material in the fixed frame 61 as the vertical plate 11 moves back and forth horizontally. The height of the push plate 13 remains unchanged, but the material accumulated in the fixed frame 61 will increase. As the material height increases, it is difficult for the push plate 13 of the original height to level the surface of the material even if it moves back and forth. At the same time, the vertical plate 11 drives the second gear 28 to move in the vertical groove 611 and engage with the second rack 35 to realize the rotation of the second gear 28. The second gear 28 rotates counterclockwise to drive the ring 29 to rotate counterclockwise. When rotating in this direction, the serrated block 30 and the serrated groove 291 are in a locked state.Therefore, the rotation of the ring 29 drives the sawtooth block 30, the fixed cylinder 32, the moving rod 33, the first spring 31 and the sleeve 27 to rotate. The horizontal bar 25 is transversely connected with the sleeve 27, that is, the sleeve 27 can move transversely relative to the horizontal bar 25 and the rotation of the sleeve 27 can drive the horizontal bar 25 to rotate. Therefore, the rotation of the sleeve 27 drives the horizontal bar 25 and the second bevel gear 26 to rotate, thereby realizing the upward movement of the first rack 12 and the push plate 13. When the second gear 28 is rotated clockwise, the sawtooth block 30 and the sawtooth groove 291 are not in the state of being connected at this time. The rotation of the second gear 28 drives the ring 29 to rotate, and the rotation of the ring 29 drives the sawtooth block 30 to rotate. However, the sawtooth block 30 will press the moving rod 33 and the first spring 31 downward during the rotation process. The moving rod 33 moves to the inside of the fixed cylinder 32. The rotation of the ring 29 will not drive the sleeve 27 to rotate, so the horizontal bar 25 will not rotate. At this time, the push plate 13 will not move downward, that is, the push plate 13 can only move upward to meet the gradually increasing material height. In addition, the push plate 13 will also be attached with a part of the material while leveling the surface of the material. When the first rack 12 moves upward to adjust the height of the push plate 13, the third gear 46 will engage with the third rack 39 to make the third gear 46 rotate. The rotation of the third gear 46 drives the support rod 41 to rotate, thereby driving the cam 42 to rotate. The rotation of the cam 42 drives the lifting rod 43 to move up and down reciprocatingly. The downward movement of the lifting rod 43 drives the vibration plate 44 to move downward to make the vibration plate 44 collide with the push plate 13, thereby driving the push plate 13 to vibrate and shake off the material attached to the push plate 13. The downward movement of the push plate 13 will stretch the third spring 45. When the lifting rod 43 moves upward, the third spring 45 will contract to produce vibration, which also drives the vibration plate 44 to contact the push plate 13 to shake off the material thereon.
