Description

Technical Field

[0001] This utility model specifically relates to a ball mill jar for the production of ceramic media materials, belonging to the field of ball mill jar technology. Background Technology

[0002] Ball milling is a key step in the production of ceramic media materials. Its purpose is to mix and grind raw materials to a fineness of micron or even submicron to obtain uniform ultrafine powder with a specific particle distribution. The quality of the powder directly determines the microstructure and final electrical properties (such as dielectric constant and dielectric loss) of the ceramic components formed and sintered in the subsequent process.

[0003] Currently, the traditional ball milling equipment widely used in industrial production and laboratory research is mainly a single drum ball mill. This equipment usually consists of a horizontally placed grinding jar that can rotate around its axis. The jar contains grinding media and the material to be ground. During operation, the grinding media are driven by the rotation of the jar to impact and rub the material to achieve crushing and mixing.

[0004] However, this traditional single-tank ball milling mode has many inherent defects and has gradually failed to meet the requirements of modern ceramic industry for high efficiency, high quality and consistency: low production efficiency and limited capacity: the effective volume of a single ball mill tank is limited, and the amount of material processed per unit time is small. If the output is to be increased, it can usually only be achieved by increasing the size of the tank or by performing multiple batch operations. The former will result in a large equipment footprint, a sharp increase in energy consumption, and the grinding efficiency may decrease due to the increase in the size of the tank; the latter will significantly increase the complexity of operation, time cost and the risk of product performance fluctuations between batches.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a ball mill jar for the production of ceramic media materials, which can improve the grinding efficiency of materials.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a ball milling jar for producing ceramic media materials, comprising a processing frame, a ball milling frame rotatably mounted inside the processing frame, ball milling jar bodies arranged in an array from top to bottom inside the ball milling frame, a driving component provided on one side surface of the ball milling frame for linkage rotation of multiple ball milling jar bodies, cooling components provided on both sides of the processing frame in linkage with the surface of the ball milling jar bodies for cooling multiple ball milling jar bodies, and a controller provided on one side surface of the processing frame.

[0008] Preferably, a driven gear is rotatably mounted on one side surface of the processing frame, and the driven gear is fixedly connected to one side of the ball mill frame. A driving gear meshes with the driven gear below, and the driving gear is fixedly connected to the processing frame.

[0009] Preferably, a rotary motor is fixedly mounted on one side surface of the processing frame via a motor frame, and the output end of the rotary motor is fixedly connected to the drive gear.

[0010] Preferably, the drive assembly includes a drive gear, which is fixedly mounted on the end of the ball mill jar body. The drive gear is located on the rear surface of the ball mill frame, and multiple drive gears at the ends of the ball mill jar bodies mesh with each other for transmission.

[0011] Preferably, the drive assembly further includes a drive motor, which is fixedly mounted on the rear surface of the ball mill frame via a mounting bracket, and the output end of the drive motor is fixedly connected to one of the drive gears.

[0012] Preferably, the two ends of the outer surface of the ball mill jar body are fixedly connected to the inner wall of the ball mill frame through support bearings.

[0013] Preferably, the cooling component includes a water supply tank, a water guide shell, and a return water tank. The water supply tank is fixedly installed on the upper side of one side of the processing frame, and the return water tank is fixedly installed on the lower side of the other side of the processing frame.

[0014] Preferably, the water guide shell is fixedly connected to the inner wall of the ball mill frame, the water guide shell has a through hole for accommodating the ball mill jar body, the ball mill jar body is located in the through hole, a water supply pipe is provided between the water supply tank and the water guide shell, the lower end of the water guide shell is connected to the return water tank through a return water pipe, and the return water tank is fixedly connected to the water supply tank through a recovery pipe.

[0015] The beneficial effects of this utility model are: 1. Through the design of the drive component, this device can synchronously drive all the ball mill jars with only one drive motor. This not only significantly simplifies the mechanical structure and reduces the manufacturing cost and energy consumption of the equipment, but more importantly, it ensures that all the ball mill jars are under the same rotation conditions, providing a highly consistent grinding environment for different batches of materials, effectively ensuring the consistency of product particle size distribution, and improving the stability and controllability of product quality.

[0016] 2. This device, through its cooling components, can promptly and efficiently remove the large amount of frictional heat generated during ball milling, preventing the slurry temperature inside the tank from becoming too high. This is crucial for heat-sensitive ceramic media materials, avoiding material denaturation, slurry deterioration, or grinding media performance degradation caused by high temperatures, thereby ensuring key indicators such as the dielectric properties of the final product.

[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] Please see Figures 1-5 As shown, a ball milling jar for producing ceramic media materials has a ball milling frame 2 rotatably mounted inside a processing frame 1. Ball milling jar bodies 3 are arranged in an array from top to bottom inside the ball milling frame 2. A drive component 4 is provided on one side surface of the ball milling frame 2 for the linkage rotation of multiple ball milling jar bodies 3. Cooling components 5 are provided on both sides of the processing frame 1 in linkage with the surface of the ball milling jar bodies 3 for cooling multiple ball milling jar bodies 3. A controller 6 is provided on one side surface of the processing frame 1.

[0025] A driven gear 7 is rotatably mounted on one side surface of the processing frame 1. The driven gear 7 is fixedly connected to one side of the ball mill frame 2. A driving gear 8 meshes below the driven gear 7 and is fixedly connected to the processing frame 1. A rotary motor 10 is fixedly mounted on one side surface of the processing frame 1 via a motor frame 9. The output end of the rotary motor 10 is fixedly connected to the driving gear 8. It should be noted that the revolution of the ball mill frame 2 is achieved through a gear transmission system. A driven gear 7 is rotatably mounted on the side wall of the processing frame 1 via a slewing bearing, and this driven gear 7 is rigidly connected to one side frame of the ball mill frame 2, for example, via a flange and... Bolts are used to directly convert the rotation of the driven gear 7 into the overall revolution of the ball mill frame 2. Directly below the driven gear 7, a driving gear 8 meshes with it. The driving gear 8 is fixed on a transmission shaft supported by the processing frame 1 to ensure its positional stability. The rotary motor 10 (selected as a low-speed, high-torque servo motor or frequency converter motor) is firmly mounted on the processing frame 1 through the motor frame 9. Its output shaft is directly connected to the transmission shaft of the driving gear 8 through a coupling. When the controller 6 starts the rotary motor 10, the power is transmitted to the driven gear 7 through the driving gear 8, ultimately driving the entire ball mill frame 2, which is fully loaded with the ball mill jar, to perform a smooth, low-speed revolution.

[0026] The drive assembly 4 includes a drive gear 401, which is fixedly mounted on the end of the grinding jar body 3. The drive gear 401 is located on the rear surface of the grinding frame 2. The drive gears 401 at the ends of multiple grinding jar bodies 3 mesh with each other for transmission. The drive assembly 4 also includes a drive motor 402, which is fixedly mounted on the rear surface of the grinding frame 2 via a mounting bracket 403. The output end of the drive motor 402 is fixedly connected to one of the drive gears 401. It should be noted that one end of the main shaft of each grinding jar body 3 extends to the rear side of the grinding frame 2, and a drive gear 401 is fixedly mounted (e.g., via a key connection and a locking nut) at this end. All drive gears of the grinding jar bodies 3 The gears 401 are arranged in an array on the ball mill frame 2 and mesh with each other to form a closed gear transmission chain. The drive motor 402 (selected as a shockproof and heat-dissipating brake motor) is fixedly mounted on the rear surface of the ball mill frame 2 through a sturdy mounting bracket 403. The drive motor 402 will then revolve with the ball mill frame 2. The output shaft of the drive motor 402 is directly connected to any one of the drive gears 401 (usually one located in the corner or center). When the controller 6 starts the drive motor 402, the power will be transmitted from the drive gear 401 to each drive gear 401 in the array through the meshing relationship, thereby driving all the ball mill jar bodies 3 to rotate at high speed around their own axes.

[0027] The outer surfaces of the grinding jar body 3 are fixedly connected to the inner walls of the grinding frame 2 via support bearings 11 at both ends. The cooling assembly 5 includes a water supply tank 501, a water guide shell 502, and a return water tank 503. The water supply tank 501 is fixedly installed on the upper side of one side of the processing frame 1, and the return water tank 503 is fixedly installed on the lower side of the other side of the processing frame 1. The water guide shell 502 is fixedly connected to the inner wall of the grinding frame 2. A through hole is provided in the water guide shell 502 to accommodate the grinding jar body 3. The grinding jar body 3 is located in the through hole. The water supply tank 501 and the water guide shell... A water supply pipe 12504 is installed between 502. The lower end of the water guide shell 502 is connected to the return water tank 503 through the return water pipe 505. The return water tank 503 is fixedly connected to the water supply tank 501 through the recovery pipe 506. It should be noted that the journals at both ends of each ball mill body 3 are mounted on the side plate of the ball mill frame 2 by high-performance support bearings 11 (such as deep groove ball bearings or self-aligning roller bearings). This design can ensure that the ball mill can rotate flexibly, bear its own weight and material load, and minimize vibration.

[0028] The water guide shell 502 is a box-type structure fixedly installed inside the ball mill frame 2 and revolving with the frame. Its material can be aluminum alloy or stainless steel with good thermal conductivity. The water guide shell 502 has an independent through hole for each ball mill jar body 3, and the inner diameter of the through hole is slightly larger than the outer diameter of the ball mill jar body 3. That is, the ball mill jar body 3 is cooled by the temperature brought by the cold water in the water guide shell 502. It should be noted that the internal or external pipelines of the water supply tank 501 and the return water tank 503 should be integrated with semiconductor cooling chips, compressor cooling systems or coil heat exchangers. Their function is to continuously cool the coolant that has been heated after absorbing heat from the ball mill jar back to the set temperature, so as to ensure the continuity and stability of the cooling effect. Water pumps are installed in the water supply pipe 12504 and the return water tank 503. Since the above water supply and cooling equipment are common existing technologies on the market, their structure is not described in this device.
