Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, specifically to a raw material mixing device for the production of ceramic balls. Background Technology

[0002] Ceramic balls, as functional components with high hardness, wear resistance, and corrosion resistance, are widely used in bearings, grinding, water treatment, and other fields. The raw materials used in their production vary depending on performance requirements, mainly including natural mineral raw materials such as clay, quartz, feldspar, and industrial powder raw materials. The particle state of these raw materials directly affects the final performance of the ceramic balls. Currently, the mixing of ceramic ball raw materials is mostly based on stirring and mixing, typically using equipment such as mixing tanks and mixers for mechanical stirring. Current mixing equipment mainly uses stirring paddle structures, such as biaxial mixers and planetary mixers, to stir and mix the raw materials, improving the uniformity of the mixture. However, due to the large initial particle size differences of different raw materials, direct mixing makes it difficult for coarse particles to be coated by fine powder, easily leading to local component segregation and affecting the mixing quality. Furthermore, the hardness, particle size characteristics, and grinding intensity of the raw materials also differ. If these are not properly addressed, the mixing efficiency of the raw materials and the final product quality of the ceramic balls will be affected.

[0003] In view of this, we propose a raw material mixing device for the production of ceramic balls. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides a raw material mixing device for ceramic ball production. This device effectively solves the problem that existing ceramic ball raw material mixing equipment lacks targeted pretreatment, making it difficult to adapt to the particle size differences and hardness characteristics of different raw materials, resulting in uneven mixing, low efficiency, and affecting the quality of the final product.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a raw material mixing device for ceramic ball production, including a main unit, including a support, an L-shaped guide hopper disposed on the support, and a mixing tank disposed at the discharge end of the L-shaped guide hopper;

[0007] The grinding unit includes a grinding roller disposed inside an L-shaped guide hopper, and a telescopic electric cylinder disposed on the top of the L-shaped guide hopper for adjusting the height of the grinding roller.

[0008] The material guiding unit includes multiple sets of rubber balls disposed below the L-shaped material guiding hopper for striking the bottom of the L-shaped material guiding hopper;

[0009] The drive unit includes a motor mounted on a support for driving the grinding roller and multiple sets of rubber balls to move.

[0010] Furthermore, the top of the support is fixedly connected to the bottom of the mixing tank, and the inlet of the mixing tank is fixedly connected to the outlet of the L-shaped guide hopper.

[0011] Furthermore, the grinding unit also includes two sets of elastic bladders fixedly connected to the inner wall of the L-shaped feed hopper, and sliders fixedly connected to the inner walls of both sets of elastic bladders.

[0012] Furthermore, the inner walls of the two sets of sliders are rotatably connected to the surface of the grinding roller, and one end of the grinding roller is fixedly connected to a universal coupling for connection with the drive unit.

[0013] Furthermore, the tops of the two sets of sliders are fixedly connected to both ends of the U-shaped frame, the inner wall of the U-shaped frame is fixedly connected to the telescopic end of the telescopic electric cylinder, and the bottom of the telescopic electric cylinder is fixedly connected to the top of the L-shaped guide hopper.

[0014] Furthermore, the material guiding unit also includes two sets of fixed shafts rotatably connected to the inner wall of the support. Multiple sets of rubber strips are fixedly connected to the surface of each set of fixed shafts, and the end of the rubber strip away from the fixed shaft is fixedly connected to the surface of the rubber ball.

[0015] Furthermore, the drive unit also includes a first synchronous wheel assembly located at the end of the universal coupling away from the grinding roller. The first synchronous wheel assembly is used for driving connection between the universal coupling and any one of the two sets of fixed shafts. The second synchronous wheel assembly is located at the end of the two sets of fixed shafts away from the first synchronous wheel assembly. The second synchronous wheel assembly is used for driving connection between the two sets of fixed shafts.

[0016] Furthermore, one side of the motor is fixedly connected to the surface of the bracket, and the motor is fixedly connected to the side of the synchronous pulley assembly away from the universal coupling via the output shaft.

[0017] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0018] This invention, by setting a targeted grinding pretreatment step before mixing, utilizes an adjustable-height grinding structure to adjust the grinding intensity according to the hardness and particle size characteristics of different raw materials. It can deeply grind and refine coarse particles with high hardness, and control the grinding degree of fine powder materials that are prone to agglomeration to avoid excessive agglomeration. This ensures that all kinds of raw materials reach a suitable particle state before entering the mixing process, solving the problem of uneven mixing caused by the large difference in the initial state of raw materials in traditional mixing processes.

[0019] The vibration and impact of the feeding unit can break up the raw material agglomeration and facilitate the smooth flow of materials. It can also prevent the fine powder after grinding from being stuck due to electrostatic adsorption, ensuring that the pre-treated raw material enters the mixing stage intact, thus achieving an efficient connection between grinding pretreatment and mixing.

[0020] Through the linkage design of the drive unit, the grinding and feeding actions are coordinated, avoiding the accumulation of raw materials or insufficient processing. This improves the uniformity of mixing and the overall processing efficiency, providing a uniform raw material base for subsequent ceramic ball forming and sintering, thereby ensuring the final product quality of the ceramic balls.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] A raw material mixing device for ceramic ball production includes a main unit 100, comprising a support 101, an L-shaped guide hopper 102 disposed on the support 101, and a mixing tank 103 disposed at the discharge end of the L-shaped guide hopper 102; the top of the support 101 is fixedly connected to the bottom of the mixing tank 103, and the inlet of the mixing tank 103 is fixedly connected to the discharge end of the L-shaped guide hopper 102; the mixing tank 103 is internally provided with a mixing rack for mixing the raw materials and corresponding driving components, which can be used for deep mixing of the raw materials;

[0033] It should be noted that the raw materials can be fed in through the feed end of the L-shaped guide hopper 102, and the L-shaped guide hopper 102 is set at an inclination. After the raw materials enter the L-shaped guide hopper 102, they can enter the mixing tank 103 for deep mixing.

[0034] Furthermore, the grinding unit 200 includes a grinding roller 201 disposed inside the L-shaped guide hopper 102, and a telescopic electric cylinder 203 disposed on the top of the L-shaped guide hopper 102 for adjusting the height of the grinding roller 201; the grinding unit 200 also includes two sets of elastic bladders 206 fixedly connected to the inner wall of the L-shaped guide hopper 102, and sliders 205 fixedly connected to the inner walls of both sets of elastic bladders 206. The inner walls of the two sets of sliders 205 are rotatably connected to the surface of the grinding roller 201, and one end of the grinding roller 201 is fixedly connected to... The universal coupling 204 is used to connect with the drive unit 400. The tops of the two sets of sliders 205 are fixedly connected to both ends of the U-shaped frame 202. The inner wall of the U-shaped frame 202 is fixedly connected to the telescopic end of the telescopic electric cylinder 203. The bottom of the telescopic electric cylinder 203 is fixedly connected to the top of the L-shaped guide hopper 102. The grinding roller 201 can rotate under the drive of the drive unit 400. During the rotation, the raw materials entering the L-shaped guide hopper 102 can be ground and crushed, thereby effectively promoting the mixing efficiency and quality of the raw materials.

[0035] It should be noted that the output is achieved through the telescopic electric cylinder 203 on the L-shaped guide hopper 102. The two sets of sliders 205 can be moved up and down by the U-shaped frame 202, thereby adjusting the height of the grinding roller 201. Since the raw materials used in the production of ceramic balls include clay, quartz, and feldspar, the particle size of different raw materials varies. Therefore, the height of the grinding roller 201 can be adjusted according to the different raw materials input, so that different raw materials can be fully ground and crushed. Furthermore, by setting elastic bladders 206 on the surface of the two sets of sliders 205, the elastic deformation stroke of the elastic bladders 206 can effectively meet the height adjustment range of the grinding roller 201. At the same time, it can achieve relative sealing of the L-shaped guide hopper 102, avoiding the problem of raw material leakage during the adjustment of the grinding roller 201. In addition, the universal coupling 204 can be connected to the drive unit 400, so that after the grinding roller 201 is adjusted to different heights, it can be driven by the drive unit 400 to rotate and grind the raw materials.

[0036] Furthermore, the guiding unit 300 includes multiple sets of rubber balls 302 disposed below the L-shaped guiding hopper 102 for striking the bottom of the L-shaped guiding hopper 102; the guiding unit 300 also includes two sets of fixed shafts 301 rotatably connected to the inner wall of the support 101, and multiple sets of rubber strips 303 are fixedly connected to the surfaces of the two sets of fixed shafts 301, with one end of the rubber strip 303 away from the fixed shaft 301 fixedly connected to the surface of the rubber balls 302; the two sets of fixed shafts 301 are respectively disposed on the side of the grinding roller 201 near the inlet end of the L-shaped guiding hopper 102 and on the side of the grinding roller 201 near the outlet end of the L-shaped guiding hopper 102;

[0037] It should be noted that when the drive unit 400 drives the two sets of fixed shafts 301 to rotate, it can drive the multiple sets of rubber strips 303 on the two sets of fixed shafts 301 to rotate, thereby swinging the rubber balls 302 on the rubber strips 303 to strike the bottom of the L-shaped guide hopper 102, so that the material can quickly enter the grinding area of ​​the grinding roller 201, and after grinding, it can quickly enter the mixing tank 103.

[0038] Finally, the drive unit 400 includes a motor 401 mounted on the bracket 101 for driving the grinding roller 201 and multiple sets of rubber balls 302 to move; the drive unit 400 also includes a first synchronous pulley assembly 402 mounted on the end of the universal coupling 204 away from the grinding roller 201, the first synchronous pulley assembly 402 is used for transmission connection between the universal coupling 204 and any one of the two sets of fixed shafts 301, and a second synchronous pulley assembly 403 is provided at the end of the two sets of fixed shafts 301 away from the first synchronous pulley assembly 402, the second synchronous pulley assembly 403 is used for transmission connection between the two sets of fixed shafts 301; one side of the motor 401 is fixedly connected to the surface of the bracket 101, and the motor 401 is fixedly connected to the side of the first synchronous pulley assembly 402 away from the universal coupling 204 through the output shaft; both the first synchronous pulley assembly 402 and the second synchronous pulley assembly 403 are composed of a synchronous belt and two sets of synchronous pulleys, used for transmission of the corresponding structures;

[0039] It should be noted that, through the output of motor 401, the grinding roller 201 can be rotated by synchronous pulley assembly 402, and one set of fixed shafts 301 can be rotated synchronously. And through synchronous pulley assembly 403, the other set of fixed shafts 301 can also be rotated.

[0040] The working principle of this utility model is as follows: Ceramic ball raw materials are fed into the feed end of the L-shaped guide hopper 102 and flow towards the grinding area and the mixing tank 103 with the help of its inclined structure. In the drive unit 400, the motor 401 drives a set of fixed shafts 301 to rotate through the synchronous wheel assembly 1 402, and the other set of fixed shafts 301 rotate synchronously through the synchronous wheel assembly 2 403. The rubber strips 303 on the surface of the fixed shafts 301 swing the rubber balls 302 with the rotation, continuously knocking the bottom of the L-shaped guide hopper 102. For clay raw materials that are easy to stick and clump, the vibration generated by the knocking can break up the clumps and avoid blocking the guide channel. For particles such as quartz with higher density, the vibration can help them move quickly towards the grinding area and prevent them from staying in the guide hopper, creating conditions for subsequent uniform grinding.

[0041] After the raw material enters the grinding area, the motor 401 drives the grinding roller 201 to rotate through the synchronous wheel assembly 402 and the universal coupling 204. At the same time, the height of the grinding roller 201 can be adjusted by the telescopic electric cylinder 203. For raw materials with high hardness such as feldspar and quartz, the telescopic electric cylinder 203 retracts, and the U-shaped frame 202 drives the slider 205 to move down, reducing the height of the grinding roller 201 and narrowing the gap between it and the bottom of the L-shaped guide hopper 102. The rotational shearing force of the grinding roller 201 is used to refine the coarse particles. For raw materials with low hardness such as clay, the telescopic electric cylinder 203 extends, raising the grinding roller 201 to avoid over-grinding and agglomeration of fine powder, and to retain an appropriate particle size. The elastic capsule 206 on the surface of the slider 205 deforms synchronously with the slider 205, which can form a relative seal on the L-shaped guide hopper 102 to prevent the raw material from leaking during the grinding process. The universal coupling 204 ensures that the grinding roller 201 can still stably receive the driving force after the height is adjusted and continue to rotate and grind.

[0042] The ground and refined raw materials flow along the L-shaped guide hopper 102 to the discharge end. The rubber ball 302 of the guide unit 300 continuously taps the bottom of the discharge end to prevent fine powder from being adsorbed on the guide hopper wall due to static electricity, ensuring that the raw materials smoothly enter the mixing tank 103. The mixing rack in the mixing tank 103 deeply mixes the ground raw materials. Since the raw material particles have been refined and more evenly distributed during the grinding stage, raw materials of different components can fully contact each other, reducing mixing dead zones. This pre-treated mixing can avoid uneven composition caused by the agglomeration of large particles, providing a uniform raw material foundation for subsequent ceramic ball forming and sintering.

[0043] The power of the motor 401 is synchronously transmitted to the grinding roller 201 and the two sets of fixed shafts 301, so that the grinding and guiding actions are coordinated. The grinding efficiency of the grinding roller 201 is matched with the striking frequency of the rubber ball 302, which avoids the accumulation of raw materials in the guide hopper or insufficient grinding, ensuring the continuity and stability of the entire mixing process, and effectively improving the mixing efficiency of ceramic ball raw materials.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
