Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, specifically to a low-noise, leak-proof ball mill. Background Technology

[0002] Ball mills are key crushing equipment in industries such as mining and building materials. They crush materials through the rotation, impact, and grinding action of grinding media such as steel balls inside the cylinder. They mainly consist of a cylinder, feeding and discharging devices, transmission and support devices. Cylinder liners protect the cylinder and optimize the grinding effect. The transmission device regulates the speed to adapt to the needs. During operation, the material moves with the cylinder and is discharged after being impacted, ground, and squeezed by the grinding media to achieve the required fineness. According to the process and material characteristics, they can be divided into grid type (high efficiency for coarse grinding), overflow type (uniform fine grinding), dry type (waterless environment), and wet type (wet process). Different types have different design focuses and can meet the diverse needs of various industries for crushing fineness, capacity and automation. They are important equipment for industrial fine processing.

[0003] For example, patent CN220900581U discloses a noise-reducing ball mill, including a base plate. Symmetrically arranged slide rails are mounted on the side walls of the base plate, and a soundproof cover is slidably mounted on the slide rails. A pull-out groove is provided on the top of the soundproof cover, and first rotating wheels are symmetrically installed inside the pull-out groove. A rotating shaft connects the first rotating wheels, and a receiving plate is provided on the rotating shaft. One end of the receiving plate is connected to a door panel, and the receiving plate and door panel are connected by a hinge, allowing one end of the soundproof cover to be opened or closed. A support frame is also fixedly installed on the base plate, and a ball mill jar is mounted on the support frame. Several second rotating wheels are located directly below the shafts at both ends of the ball mill jar, all tangent to the shafts at both ends of the ball mill jar. However, in the use of this existing device, the high-speed collision and friction between the material and the grinding media inside the cylinder generates significant noise. These noises are not only intense but also have a wide range of propagation, causing serious noise pollution to the surrounding production environment and residents' living environment, interfering with normal work and life order. Furthermore, during the material processing process, the material can only be stirred and ground in a fixed single direction, making the movement trajectory of the material in the cylinder relatively fixed. The material in some areas is difficult to be fully stirred and ground, resulting in incomplete and uneven material processing, which affects the crushing quality and processing efficiency of the material.

[0004] Therefore, in order to solve such problems, we propose a low-noise, leak-proof ball mill. Utility Model Content

[0005] The purpose of this invention is to provide a low-noise, leak-proof ball mill to solve the problem mentioned in the background art. In existing devices, the high-speed collision and friction between materials and grinding media within the cylinder generates significant noise. This noise is not only intense but also widespread, causing serious noise pollution to the surrounding production and residential environments, disrupting normal work and life. Furthermore, during material processing, the material can only be stirred and ground in a fixed, single direction, resulting in a relatively fixed trajectory of the material within the cylinder. This makes it difficult to achieve sufficient stirring and grinding in certain areas, leading to incomplete and uneven material processing, which affects the crushing quality and processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-noise, leak-proof ball mill, comprising a base, legs fixedly connected to all four sides of the top of the base, mounting rings fixedly connected to the top of the legs, a tank movably connected inside the mounting rings, an annular groove formed on the inner wall of the mounting rings, annular components fixedly connected to both ends of the outer wall of the tank, the tanks being rotatably connected to each other via the annular grooves and annular components, a fixing component fixedly connected to the right side of the top of the base, a servo motor fixedly connected to the outer wall of the fixing component on the right side of the top of the base, a rotating shaft fixedly connected to the output end of the servo motor, a gear fixedly connected to the rotating shaft, and a gear ring fixedly connected to the outer wall of the tank, the gear meshing with the gear ring.

[0007] Furthermore, a discharge trough is provided on the outer wall of the tank, and a baffle is rotatably connected to the discharge trough. Limit blocks are fixedly connected to the bottom of both the tank and the baffle, and limit bolts are movably connected to the limit blocks.

[0008] Furthermore, an installation groove is provided on the inner wall of the tank, and sound insulation cotton is fixedly connected in the installation groove. Engaging grooves are evenly provided on the inner wall of the installation groove on the inner wall of the tank, and engaging blocks are evenly fixedly connected on the outer wall of the sound insulation cotton.

[0009] Furthermore, a rotating rod is rotatably connected to the tank body, and stirring rods are uniformly fixedly connected to the outer wall of the rotating rod.

[0010] Furthermore, a drive pulley is fixedly connected to the right end of the rotating shaft on the fixing member, and a driven pulley is fixedly connected to the right end of the rotating rod. Belts are sleeved on the drive pulley and the driven pulley.

[0011] Furthermore, a top rod is fixedly connected to the top of the base, and a discharge plate is fixedly connected to the top rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: a low-noise, leak-proof ball mill, adopting a novel structural design, the specific details of which are as follows:

[0013] (1) The low-noise leak-proof ball mill has sound insulation cotton fixed to the inner wall of the tank through the mounting groove and the locking structure. It can directly absorb the noise generated by the collision and friction between the material and the grinding medium, and reduce the noise transmission from the source. The locking installation design of the sound insulation cotton and the tank not only ensures the stability of the sound insulation structure, but also facilitates disassembly and replacement in the later stage, and maintains the noise reduction effect continuously. The discharge chute of the tank is closed by the baffle. The baffle is fixed with the limit block at the bottom of the tank in conjunction with the limit bolt. It can be tightly closed when the ball mill is working to prevent the material from leaking from the discharge port. The tank and the mounting ring are connected by the annular groove and the annular part. With the precise meshing transmission gear and tooth ring, the risk of gap leakage caused by the shaking of the tank is reduced.

[0014] (2) The low-noise leak-proof ball mill has a rotating rod and a stirring rod inside the tank. The stirring rod rotates with the rotating rod, which can perform secondary stirring of the material to avoid material accumulation and enhance the contact frequency between the grinding media and the material. The servo motor drives the tank to rotate through gears and gear rings, and at the same time drives the rotating rod to rotate in the opposite direction through the active pulley, belt and driven pulley, forming a compound motion of "tank rotation + stirring rod in the opposite direction", which greatly improves the grinding uniformity.

[0015] Furthermore, the discharge plate is fixed to the top of the base, which can guide the material to flow in a specific direction during discharge, avoiding material spillage and environmental pollution. The base is connected to the mounting ring through the support legs, and the fasteners enhance the overall structural support, ensuring the stability of the tank when rotating at high speed, and reducing vibration, noise and component wear.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides the following technical solution: a low-noise, leak-proof ball mill.

[0025] Example 1: A low-noise, leak-proof ball mill, through the synergistic action of components such as gear 21, gear ring 22, and mounting ring 12, ensures that the material and grinding media inside the tank 13 undergo sufficient high-speed friction. Sound insulation cotton 132 is installed via locking blocks and locking grooves, effectively absorbing the noise generated during ball mill operation and reducing noise propagation. Multiple grinding protrusions are evenly distributed on the inner wall of the tank 13, enhancing the grinding effect between the material and the inner cylinder, improving crushing efficiency, and preventing excessive noise generated during high-speed collisions and friction between the material and grinding media inside the cylinder. This noise is not only intense but also has a wide propagation range, causing serious noise pollution to the surrounding production environment and residential living environment, disrupting normal work and life order, such as... Figure 1 - Figure 5As shown, a low-noise, leak-proof ball mill includes a base 1. Support legs 11 are fixedly connected to all four sides of the top of the base 1. A mounting ring 12 is fixedly connected to the top of each support leg 11. A tank 13 is movably connected within the mounting ring 12. An annular groove is formed on the inner wall of the mounting ring 12. Annular components are fixedly connected to both ends of the outer wall of the tank 13. The tank 13 is rotatably connected to the annular components via the annular groove. A fixing member 2 is fixedly connected to the right side of the top of the base 1. A servo motor is fixedly connected to the outer wall of the fixing member 2 on the right side of the top of the base 1. A rotating shaft is fixedly connected to the output end of the servo motor. A gear 21 is fixedly connected to the rotating shaft, and a gear ring 22 is fixedly connected to the outer wall of the tank body 13. The gear 21 and the gear ring 22 are meshed together. A discharge trough is provided on the outer wall of the tank body 13, and a baffle 131 is rotatably connected to the discharge trough. Limiting blocks 14 are fixedly connected to the bottom of both the tank body 13 and the baffle 131. Limiting bolts are movably connected to the limiting blocks 14. An installation groove is provided on the inner wall of the tank body 13, and sound insulation cotton 132 is fixedly connected in the installation groove. Engaging grooves are evenly provided on the inner wall of the installation groove on the inner wall of the tank body 13, and engaging blocks are evenly fixedly connected to the outer wall of the sound insulation cotton 132.

[0026] The servo motor on the right-side fixing part 2 of the start base 1 drives the rotating shaft to rotate. The gear 21 on the rotating shaft meshes with the gear ring 22 on the outer wall of the tank 13, thereby driving the tank 13 to rotate in the annular groove of the mounting ring 12 through the annular parts at both ends. When the tank 13 rotates, the grinding media inside, such as steel balls, move in a circular motion with the tank 13. The material is impacted and ground by gravity and centrifugal force. The sound insulation cotton 132 on the inner wall of the tank 13 is tightly fixed to the locking groove of the inner wall of the tank 13 by the locking block. When the material collides with the grinding media, the sound insulation cotton 132 absorbs the sound wave energy through the porous structure, reducing the intensity of noise propagation to the outside. During the grinding process, the baffle 131 is fixed to the discharge chute by the limiting block 14 and the limiting bolt, sealing the internal space of the tank 13 and preventing the material from leaking from the discharge port due to centrifugal force.

[0027] Example 2: Unlike Example 1, through the coordinated action of the active pulley 24, driven pulley 241, belt 242, and stirring rod 231, the stirring rod 231 rotates in different directions than the tank 13. This allows for more thorough friction between the material and the grinding media, preventing the material from being stirred and ground only in a fixed single direction during processing. This avoids situations where the material's trajectory within the tank is relatively fixed, resulting in insufficient stirring and grinding in certain areas, leading to incomplete and uneven material processing, and affecting the crushing quality and processing efficiency. Figure 6As shown, a rotating rod 23 is rotatably connected to the tank body 13, and stirring rods 231 are evenly fixedly connected to the outer wall of the rotating rod 23. A driving pulley 24 is fixedly connected to the right end of the rotating shaft on the fixing part 2, and a driven pulley 241 is fixedly connected to the right end of the rotating rod 23. A belt 242 is sleeved on the driving pulley 24 and the driven pulley 241. A top rod is fixedly connected to the top of the base 1, and a discharge plate 3 is fixedly connected to the top rod.

[0028] The rotating shaft of the servo motor simultaneously drives the active pulley 24 on the right end to rotate. The active pulley 24 drives the driven pulley 241 to rotate through the belt 242. The driven pulley 241 is fixedly connected to the rotating rod 23. Therefore, the rotating rod 23 rotates with the driven pulley 241. Since the transmission directions of the active pulley 24 and the driven pulley 241 are opposite, the rotation direction of the rotating rod 23 is opposite to that of the tank 13. The stirring rod 231 on its outer wall stirs the material in the tank in the opposite direction, so that the material and the grinding medium are fully mixed and the phenomenon of local un-grinding is avoided. When the material is ground, the servo motor is turned off, the limit bolt on the limit block 14 is loosened, the baffle 131 is rotated to open the discharge chute, and the material falls onto the discharge plate 3 under the action of gravity and is guided out by the discharge plate 3.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
