Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a ceramic ball mill. Background Technology

[0002] Ball mills are common machines used for grinding materials into powder. Ceramic balls are relatively stable, making them suitable for grinding certain materials. However, ball mills have some shortcomings and areas for improvement: 1. In general ball mills, the individual drive mechanism leads to significant wear during rotation, requiring the addition of other drive structures and reduction of rotational pressure; 2. The grinding process generates considerable vibration and knocking noise, resulting in high noise levels. Furthermore, the ceramic balls' unidirectional trajectory within the mill leads to insufficient grinding force. Therefore, we propose a ceramic ball mill. Utility Model Content

[0003] The main objective of this invention is to provide a ceramic ball mill that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A ceramic ball mill includes a support mechanism. A grinding cylinder mechanism is interspersed in the upper part of the support mechanism. A feed inlet is fixedly connected to the left end of the grinding cylinder mechanism, and a discharge outlet is fixedly connected to the lower right end of the grinding cylinder mechanism. An extension rod is fixedly connected to the middle of the right end of the grinding cylinder mechanism. An outer plate is fixedly connected to the left front end of the support mechanism. A power motor is fixedly connected to the left end of the outer plate. Two sets of turntables are interspersed and fixedly connected to the left end of the output end of the power motor. A gear is fixedly connected to the leftmost end of the output end of the power motor. An outer ring gear is fixedly connected to the outer surface of the left end of the grinding cylinder mechanism.

[0005] Preferably, the support mechanism includes a rectangular frame. Several sets of support plates are fixedly connected to the upper left and upper right portions of the rectangular frame. A cylindrical ring is fixedly connected to the upper end of each set of support plates on the same side. Several sets of rollers are evenly spaced on the inner walls of both sets of cylindrical rings. Support frames are fixedly connected to the upper left and upper right portions of the rectangular frame. Connecting rods are movably arranged at the front and rear of each set of support frames. Auxiliary shafts are inserted and fixedly connected to the left and right ends of each set of connecting rods. A turntable is inserted and fixedly connected to the left end of each set of connecting rods. By adopting the above technical solution, the auxiliary shaft contacts the outer wall of the grinding cylinder mechanism, facilitating the rotation of the grinding cylinder mechanism.

[0006] Preferably, the turntable at the output end of the power motor and the turntable on the connecting rod are both fitted with a connecting belt, and the rectangular frame is fixedly connected to the outer plate. By adopting the above technical solution, the grinding cylinder mechanism can be driven to rotate through the meshing engagement of the gear and the external gear ring.

[0007] Preferably, the feed inlet passes through the left cylindrical ring, the extension rod passes through the right cylindrical ring, and the four sets of auxiliary shafts contact the grinding cylinder mechanism. By adopting the above technical solution, the rollers inside the cylindrical ring can reduce the friction during rotation, making it easier to drive its rotation.

[0008] Preferably, the grinding cylinder mechanism includes a first shell, a second shell fixedly connected to the inner wall of the first shell, a third shell fixedly connected to the inner wall of the second shell, and several sets of protruding cones fixedly connected at equal intervals on the left and right sides of the inner wall of the third shell. A spacer ring is fixedly connected to the right side of the inner wall of the third shell, and several sets of perforations are evenly spaced on the spacer ring. By adopting the above technical solution, the spacer ring can divide the internal space into two parts: a coarse grinding area on the left and a fine grinding area on the right.

[0009] Preferably, the spacer ring is slightly flared, the first shell is made of carbon steel, the second shell is made of elastic silicone, and the third shell is made of ceramic. By adopting the above technical solution, the protruding cone can impact the grinding ball, changing its trajectory and throwing direction, thereby increasing the grinding force.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a support mechanism, the auxiliary shaft on the support mechanism can support the upper grinding cylinder mechanism from the bottom, while the rotating auxiliary shaft can drive it to rotate, reducing the wear of gears and outer ring gears. The roller inside the cylindrical ring can reduce the friction during rotation.

[0011] 2. By setting up a grinding cylinder mechanism, the protruding cone on the grinding cylinder mechanism can collide with the ceramic ball to change its path, increase the grinding force, and at the same time make it easier to grind it finer. The second shell made of elastic silicone material can reduce the impact vibration of the ceramic ball and absorb some of the noise. Attached Figure Description

[0017] Please see Figure 1-4 This utility model provides a technical solution: A ceramic ball mill includes a support mechanism 1. A grinding cylinder mechanism 2 is interspersed in the upper part of the support mechanism 1. A feed inlet 3 is fixedly connected to the left end of the grinding cylinder mechanism 2. A discharge outlet 4 is fixedly connected to the lower right end of the grinding cylinder mechanism 2. An extension rod 5 is fixedly connected to the middle of the right end of the grinding cylinder mechanism 2. An outer plate 6 is fixedly connected to the left front end of the support mechanism 1. A power motor 7 is fixedly connected to the left end of the outer plate 6. Two sets of turntables 8 are interspersed and fixedly connected to the left end of the output end of the power motor 7. A gear 9 is fixedly connected to the leftmost end of the output end of the power motor 7. An outer ring gear 10 is fixedly connected to the outer surface of the left end of the grinding cylinder mechanism 2.

[0018] In this embodiment, the support mechanism 1 includes a rectangular frame 11. Several sets of support plates 12 are fixedly connected to the upper left and upper right parts of the rectangular frame 11. The upper ends of the several sets of support plates 12 on the same side are fixedly connected to a cylindrical ring 13. Several sets of rollers 14 are evenly spaced on the inner walls of the two sets of cylindrical rings 13. Support frames 15 are fixedly connected to the upper left and upper right parts of the rectangular frame 11. Connecting rods 16 are movably arranged at the front and rear of the two sets of support frames 15. Auxiliary shafts 17 are inserted and fixedly connected to the left and right sides of the two sets of connecting rods 16. Turntables 8 are inserted and fixedly connected to the left ends of the two sets of connecting rods 16. The turntable 8 at the output end of the power motor 7 and the turntable 8 on the connecting rod 16 are connected to a connecting belt 18. The rectangular frame 11 is fixedly connected to the outer plate 6. The feed port 3 passes through the cylindrical ring 13 on the left. The extension rod 5 passes through the cylindrical ring 13 on the right. The four sets of auxiliary shafts 17 are in contact with the grinding cylinder mechanism 2. Through the above scheme, the auxiliary shaft 17 on the support mechanism 1 can be driven to rotate, which not only supports the upper grinding cylinder mechanism 2, but also drives the upper grinding cylinder mechanism 2 to rotate, reducing the pressure on the left gear 9 and the outer ring gear 10. The roller 14 on the inner wall of the cylindrical ring 13 can reduce the friction when the grinding cylinder mechanism 2 rotates.

[0019] In this embodiment, the grinding cylinder mechanism 2 includes a first shell 19, a second shell 20 fixedly connected to the inner wall of the first shell 19, a third shell 21 fixedly connected to the inner wall of the second shell 20, and several sets of protruding cones 22 fixedly connected at equal intervals on the left and right sides of the inner wall of the third shell 21. A spacer ring 23 is fixedly connected to the right side of the inner wall of the third shell 21, and several sets of perforations 24 are evenly spaced on the spacer ring 23. The spacer ring 23 is slightly flared. The first shell 19 is made of carbon steel, the second shell 20 is made of elastic silicone, and the third shell 21 is made of ceramic. Through the above scheme, the protruding cones 22 fixedly connected to the inner wall of the third shell 21 on the grinding cylinder mechanism 2 can change the movement trajectory of the ceramic ball and improve the grinding force. The spacer ring 23 and the perforations 24 can move the ground material to the right and continue grinding on the right side. At the same time, the second shell 20 is made of elastic rubber, which can reduce the vibration of impact.

[0020] It should be noted that this utility model is a ceramic ball mill. During operation, ceramic balls are first fed into the interior of the third shell 21 through the feed inlet 3, and then more material is fed in, driving the power motor 7. The gear 9 at the output end of the power motor 7 meshes with the outer ring gear 10, causing the grinding cylinder mechanism 2 to rotate and grind the internal raw material. The second shell 20 on the grinding cylinder mechanism 2 is made of elastic rubber, which reduces the impact force when the ceramic balls fall. Simultaneously, a protruding cone 22 is fixedly connected to the inner wall of the third shell 21, which can change the movement trajectory of the ceramic balls, adding various parabolic trajectories and improving the grinding of the material. During grinding, the turntable 8 driven by the connecting belt 18 also begins to rotate, and the auxiliary shaft 17 on the connecting rod 16 is also driven to rotate. The auxiliary shaft 17 not only supports the upper grinding cylinder mechanism 2 at the bottom, but also drives the grinding cylinder mechanism 2 to rotate together during rotation, reducing the pressure on the gear 9 and the outer ring gear 10 and extending its service life. The feed port 3 on the left and the extension rod 5 on the right are inserted into the cylindrical ring 13 with roller 14, which further reduces the friction during rotation. After the initial grinding, the material passes through the hole 24 to the space on the right for further grinding, which can improve the grinding efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
