Description

Technical Field

[0001] This invention relates to the field of ball mill technology, and more particularly to a ball mill with enhanced stirring. Background Technology

[0002] Ball mills are commonly used equipment in the field of material crushing. They use the movement of grinding media in the cylinder to impact and grind materials, thereby refining the materials. They are used in many industrial fields such as mining, building materials, chemicals, and metallurgy.

[0003] The existing ball mill structure mainly consists of a cylinder, grinding media, a drive unit, and a feeding and discharging device. The drive unit drives the cylinder to rotate, causing the grinding media inside the cylinder to be lifted to a certain height under the action of centrifugal force and friction, and then fall or slide freely, generating impact, grinding and squeezing effects on the material inside the cylinder to achieve the purpose of crushing the material. The feeding and discharging devices are responsible for continuously or intermittently feeding the material to be crushed into the cylinder and discharging the qualified material in a timely manner.

[0004] When processing high-viscosity materials, existing technologies often result in the materials adhering to the inner surface of the grinding cylinder, reducing the effective contact area between the grinding media and the materials. This not only reduces the grinding effect but also increases the difficulty of cleaning the equipment. For high-hardness materials, traditional single grinding methods may require a longer grinding time, affecting overall production efficiency.

[0005] Therefore, a ball mill with enhanced stirring is proposed to solve the problems of low grinding efficiency, easy material adhesion, and difficult cleaning of traditional ball mills. Summary of the Invention

[0006] The purpose of this invention is to provide a ball mill with enhanced stirring to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A ball mill with enhanced stirring includes a support base, a rotating cylinder, a rotating assembly, and a stirring assembly. The rotating assembly includes a large gear and a small gear, and the stirring assembly includes a rotating shaft. An isolation cover plate is fixedly connected to the inner wall of the rotating cylinder. A transmission cavity is formed between one side of the isolation cover plate and one side of the inner wall of the rotating cylinder. A filter cylinder is fixedly connected between one side of the isolation cover plate and the side of the inner wall of the rotating cylinder away from the transmission cavity. A storage cavity is formed between the outer side of the filter cylinder and the inner side of the rotating cylinder. One end of the rotating shaft passes through the rotating cylinder and the isolation cover plate and extends to one side of the inner wall of the rotating cylinder. A spiral stirring blade is fixedly connected to the surface of the rotating shaft inside the filter cylinder. One side of the large gear is fixedly connected to one side of the rotating cylinder.

[0008] Preferably, the rotating cylinder has a sealing cap threadedly connected to its surface. The sealing cap passes through the rotating cylinder and the filter cylinder and extends into the interior of the filter cylinder. The rotating shaft is located on the side of the rotating cylinder near the sealing cap, and the surface of the rotating shaft is rotatably connected to the interior of the rotating cylinder and the isolation cover plate.

[0009] Preferably, a motor cylinder is fixedly connected to one side of the rotating cylinder, and a built-in motor is fixedly connected inside the motor cylinder. The output shaft of the built-in motor is fixedly connected to one end of the rotating shaft through a coupling.

[0010] Preferably, a buffer frame is fixedly connected to the top of the support base, and the number of buffer frames is set to two. The top of the two buffer frames is fixedly connected to a support frame and a rotating sleeve respectively, and one side of the surface of the rotating cylinder is rotatably connected to the inner side of the rotating sleeve.

[0011] Preferably, a large support frame and a small support frame are fixedly connected to the top of the support frame, a motor base is fixedly connected to the side of the top of the support frame away from the small support frame, and an external motor is fixedly connected to the top of the motor base.

[0012] Preferably, the output shaft of the external motor is fixedly connected to the center of one side of the pinion via a coupling, and an auxiliary roller is fixedly connected to the center of the side of the pinion away from the external motor. The surface of the auxiliary roller is rotatably connected to the inner side of the small support frame.

[0013] Preferably, a support roller is fixedly connected to the center of the side of the large gear away from the rotating cylinder, the surface of the support roller is rotatably connected to the inner side of the large support frame, and the surface of the small gear meshes with the surface of the large gear.

[0014] Preferably, the storage chamber is provided with an auxiliary rotating rod located directly below the sealing cover. One end of the auxiliary rotating rod passes through the isolation cover and extends into the interior of the transmission chamber. A small pulley is fixedly connected to the end of the auxiliary rotating rod located inside the transmission chamber.

[0015] Preferably, a large pulley is fixedly connected to the surface of the rotating shaft inside the transmission cavity, and the surface of the large pulley is connected to the surface of the small pulley via a belt.

[0016] Preferably, a vibrating cam is fixedly connected to the surface of the auxiliary rotating rod inside the storage cavity, the two ends of the auxiliary rotating rod are rotatably connected to the two sides of the inner wall of the rotating cylinder, and the surface of the auxiliary rotating rod is rotatably connected to the inner side of the isolation cover plate.

[0017] The beneficial effects of this invention are as follows: This invention achieves a dual effect on materials by setting the spiral stirring blades and the rotating cylinder to work together. When the external motor drives the pinion to rotate, the pinion drives the large gear and the rotating cylinder fixed to it to rotate synchronously. Centrifugal force is used to make the grinding media impact and grind the materials. At the same time, the built-in motor drives the rotating shaft and the spiral stirring blades to rotate independently. The spiral stirring blades can not only force the materials in the filter cylinder to stir, break up the material agglomeration, and increase the contact opportunity between the grinding media and the materials, but also push the materials to move towards the filter surface of the filter cylinder through the spiral structure, accelerating the filtration and separation of qualified materials. The rotating shaft drives the auxiliary rotating rod to rotate within the transmission chamber via a large pulley, belt, and small pulley. This causes the vibrating cam to vibrate within the storage chamber, effectively preventing the filtered material from adhering and accumulating on the chamber wall. This ensures smooth material discharge, significantly improving grinding efficiency and effectiveness while reducing the difficulty of equipment cleaning. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-5A ball mill with enhanced stirring includes a support base 1, a rotating cylinder 2, a rotating assembly and a stirring assembly, wherein the rotating assembly includes a large gear 3 and a small gear 4, and the stirring assembly includes a rotating shaft 5; An isolation cover plate 6 is fixedly connected to the inner wall of the rotating cylinder 2. A transmission cavity 7 is formed between one side of the isolation cover plate 6 and one side of the inner wall of the rotating cylinder 2. A filter cylinder 8 is fixedly connected between one side of the isolation cover plate 6 and the side of the inner wall of the rotating cylinder 2 away from the transmission cavity 7. A storage cavity 9 is formed between the outer side of the filter cylinder 8 and the inner side of the rotating cylinder 2. One end of the rotating shaft 5 passes through the rotating cylinder 2 and the isolation cover plate 6 and extends to one side of the inner wall of the rotating cylinder 2. A spiral stirring blade 10 is fixedly connected to the surface of the rotating shaft 5 inside the filter cylinder 8. One side of the large gear 3 is fixedly connected to one side of the rotating cylinder 2.

[0022] The isolation cover plate 6 divides the internal space of the rotating cylinder 2 into two parts. A transmission cavity 7 for accommodating transmission components is formed between one side of the isolation cover plate 6 and one side of the inner wall of the rotating cylinder 2. The filter cylinder 8 is a hollow structure with filter holes on the side wall. A storage cavity 9 for temporarily storing qualified materials after grinding is naturally formed between its outer side and the inner side of the rotating cylinder 2. The spiral direction of the spiral stirring blade 10 is adapted to the direction in which the material needs to be pushed. One side of the large gear 3 is fixed to one end face of the rotating cylinder 2 to drive the rotating cylinder 2. The rotating cylinder 2 rotates stably. At this time, the grinding media in the filter cylinder 8 is lifted to a certain height under the action of centrifugal force and then falls, generating impact and grinding action on the material. The rotating shaft 5 rotates, driving the spiral stirring blade 10 to rotate independently inside the filter cylinder 8. The spiral stirring blade 10 forcibly stirs the material, so that the material and the grinding media can fully contact and mix, effectively breaking the material agglomeration. And through the spiral structure, the material is pushed to move towards the filter surface of the filter cylinder 8. The qualified ground material enters the storage chamber 9 after being filtered by the filter cylinder 8. In this process, the rotating shaft 5 drives the small pulley 24 to rotate in the transmission chamber 7 through the large pulley 25 and the belt. The small pulley 24 drives the auxiliary rotating rod 23 to rotate. The vibrating cam 26 on the auxiliary rotating rod 23 vibrates in the storage chamber 9 to prevent the material entering the storage chamber 9 from sticking and accumulating on the chamber wall.

[0023] Furthermore, a sealing cover 11 is threadedly connected to the surface of the rotating cylinder 2. The sealing cover 11 passes through the rotating cylinder 2 and the filter cylinder 8 and extends into the interior of the filter cylinder 8. The rotating shaft 5 is located on the side of the rotating cylinder 2 near the sealing cover 11. The surface of the rotating shaft 5 is rotatably connected to the interior of the rotating cylinder 2 and the isolation cover plate 6.

[0024] The structural design of the sealing cover 11 allows it to penetrate the corresponding openings of the rotating cylinder 2 and the filter cylinder 8 and extend into the interior of the filter cylinder 8, thereby forming an effective seal for the filter cylinder 8. The rotating shaft 5 is rotatably connected to the interior of the rotating cylinder 2 and the isolation cover plate 6 through bearings to ensure smooth rotation.

[0025] Furthermore, a motor cylinder 12 is fixedly connected to one side of the rotating cylinder 2, and a built-in motor 13 is fixedly connected inside the motor cylinder 12. The output shaft of the built-in motor 13 is fixedly connected to one end of the rotating shaft 5 through a coupling.

[0026] A motor cylinder 12 is fixedly connected to one side of the rotating cylinder 2, specifically the side away from the large gear 3. An internal motor 13 is fixedly installed inside the motor cylinder 12, which provides power for the rotation of the rotating shaft 5 and the spiral stirring blades 10.

[0027] Furthermore, a buffer frame 14 is fixedly connected to the top of the support base 1. Two buffer frames 14 are provided, and a support frame 15 and a rotating sleeve 16 are respectively fixedly connected to the top of each buffer frame 14. One side of the surface of the rotating cylinder 2 is rotatably connected to the inner side of the rotating sleeve 16. A large support rotating frame 17 and a small support rotating frame 18 are respectively fixedly connected to the top of the support frame 15. A motor base 19 is fixedly connected to the side of the top of the support frame 15 away from the small support rotating frame 18. The top of the motor base 19 is fixedly connected to... An external motor 20 is connected; the output shaft of the external motor 20 is fixedly connected to the center of one side of the small gear 4 via a coupling, and an auxiliary roller 21 is fixedly connected to the center of the side of the small gear 4 away from the external motor 20. The surface of the auxiliary roller 21 is rotatably connected to the inner side of the small support frame 18; a support roller 22 is fixedly connected to the center of the side of the large gear 3 away from the rotating cylinder 2, and the surface of the support roller 22 is rotatably connected to the inner side of the large support frame 17. The surfaces of the small gear 4 and the large gear 3 mesh with each other.

[0028] Two buffer frames 14 are fixedly connected to the top of the support base 1. Buffer elements such as springs can be installed inside the buffer frames 14 to reduce vibration during equipment operation. The inner side of the rotating sleeve 16 is rotatably connected to the surface of the rotating cylinder 2 near the motor cylinder 12 via bearings, forming support for one end of the rotating cylinder 2. The top of the support frame 15 is fixedly connected to the outer side of the large support frame 17, away from the small support frame 18. An external motor 20 is fixedly installed on the top of the motor frame 19. The surface of the auxiliary roller 21 is rotatably connected to the inner side of the small support frame 18 via bearings, providing stable support for the rotation of the small gear 4. The surface of the support roller 22 is rotatably connected to the inner side of the large support frame 17 via bearings. At the same time, the teeth of the small gear 4 mesh with the teeth of the large gear 3. When the external motor 20 drives the small gear 4 to rotate, it can drive the large gear 3 and the rotating cylinder 2 to rotate as a whole.

[0029] Furthermore, an auxiliary rotating rod 23 is provided in the storage chamber 9 directly below the sealing cover 11. One end of the auxiliary rotating rod 23 passes through the isolation cover plate 6 and extends into the interior of the transmission chamber 7. A small pulley 24 is fixedly connected to one end of the auxiliary rotating rod 23 inside the transmission chamber 7. A large pulley 25 is fixedly connected to the surface of the rotating shaft 5 inside the transmission chamber 7. The surface of the large pulley 25 is connected to the surface of the small pulley 24 via a belt. A vibrating cam 26 is fixedly connected to the surface of the auxiliary rotating rod 23 inside the storage chamber 9. Both ends of the auxiliary rotating rod 23 are rotatably connected to the two sides of the inner wall of the rotating cylinder 2, and the surface of the auxiliary rotating rod 23 is rotatably connected to the inner side of the isolation cover plate 6.

[0030] An auxiliary rotating rod 23 is located inside the storage chamber 9, directly below the sealing cover 11. When the rotating shaft 5 rotates, the auxiliary rotating rod 23 can be driven to rotate synchronously via belt transmission. The two ends of the auxiliary rotating rod 23 are rotatably connected to the two sides of the inner wall of the rotating cylinder 2 via bearings, and its surface is also rotatably connected to the inner side of the isolation cover plate 6 via bearings to ensure stable rotation. During rotation, the vibrating cam 26 can intermittently impact or vibrate the inner wall of the storage chamber 9. The entire auxiliary rotating rod 23 is driven to rotate in the transmission chamber 7 via the rotating shaft 5 through the large pulley 25, belt and small pulley 24, so that the vibrating cam 26 vibrates in the storage chamber 9. This effectively prevents the material entering the storage chamber 9 after filtration from sticking and accumulating on the chamber wall, ensuring smooth material discharge, thereby significantly improving grinding efficiency and effect, and reducing the difficulty of equipment cleaning.

[0031] Working Principle: Existing technologies often result in materials adhering to the inner surface of the filter cylinder when processing high-viscosity materials, reducing the effective contact area between the grinding media and the material. This not only diminishes the grinding effect but also increases the difficulty of cleaning the equipment. For high-hardness materials, traditional single-grinding methods may require longer grinding times, impacting overall production efficiency. First, the material to be ground and an appropriate amount of grinding media are introduced into the filter cylinder 8 through the sealing cap 11. Then, the sealing cap 11 is tightened to ensure a tight seal. The rotation of the rotating cylinder 2 and the independent stirring of the spiral stirring blades 10 form a dual grinding mechanism. The rotating cylinder 2 drives the grinding media to impact and grind the material, while the spiral stirring blades 10 break up material agglomerates through forced stirring, increasing the contact probability between the material and the grinding media. Especially for high-viscosity materials, this effectively reduces adhesion to the inner wall of the filter cylinder 8, ensuring the grinding media's role is fully utilized. For high-hardness materials, this dual action significantly shortens grinding time and improves grinding efficiency. Simultaneously, the rotating shaft 5 drives the auxiliary rotating rod 23 and the vibrating cam 26 to vibrate within the storage chamber 9 via a pulley drive. This promptly shakes the filtered material off the walls of the storage chamber 9, preventing accumulation and blockage, ensuring smooth material discharge, and reducing the workload of subsequent equipment cleaning. After grinding is complete, the external motor 20 and the internal motor 13 are turned off, and the sealing cover 11 is unscrewed to remove the material from the storage chamber 9. Furthermore, the buffer frame 14 effectively absorbs vibrations generated during equipment operation, reducing the impact on the support base 1 and the surrounding environment, and improving the stability and safety of equipment operation. The overall structure is compact, with all components working collaboratively, specifically addressing problems in existing technologies such as low grinding efficiency, easy material adhesion, and difficult cleaning.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
