Description

Technical Field

[0001] This utility model relates to the field of ingredient mixing technology, and in particular to an ingredient mixing machine for ultrafine powder making. Background Technology

[0002] In the batching stage of ultrafine powder production, adequate dispersion of raw materials is a core prerequisite for ensuring uniform mixing. Current traditional batching equipment has significant shortcomings in handling dispersion during the raw material conveying stage: the conveying structure is mostly a simple channel design, only capable of directional transport of raw materials, lacking a dedicated dispersion mechanism. During conveying, raw materials are prone to agglomeration due to compression and stacking. These agglomerates, when directly introduced into subsequent processes, hinder effective blending between different raw materials, significantly reducing mixing quality. Simultaneously, the insufficient smoothness of the inner walls of traditional conveying components and the lack of agitation structures cause localized stagnation of raw materials during transport, preventing some materials from participating in the mixing in a timely manner and resulting in significant differences in the degree of dispersion within batches. In the bottom mixing stage of the equipment, traditional designs are equally ineffective in improving dispersion: bottom agitation often uses unidirectional rotating blades, which cause the raw materials to easily form regular flow trajectories under the agitation force, making it difficult to effectively break up agglomerated materials and keeping them in a clumped state. In addition, traditional agitation components can only agitate the surface of the raw materials and cannot penetrate deep into the bottom accumulation area to form three-dimensional dispersion. This results in the raw materials at the bottom being in a static and compacted state for a long time, creating a significant difference in dispersion compared to the raw materials at the top, which seriously affects the compositional uniformity of the ultrafine powder product.

[0003] Therefore, it is necessary to provide a batching machine for ultrafine powder making to solve the above-mentioned technical problems. Utility Model Content

[0004] This invention provides a batching machine for ultrafine powder making, which solves the problems in the background art.

[0005] To address the aforementioned technical problems, this utility model provides an ultrafine powder mixing machine, comprising a main body serving as the overall supporting foundation. A mixing conveyor cylinder is installed above and inside the main body, forming an enclosing relationship. A raw material tank is mounted on the top surface of the main body, and the raw material tank is connected to the mixing conveyor cylinder. This connection allows the raw material to smoothly enter the mixing conveyor cylinder from the raw material tank. Multiple equally spaced filter holes are perforated along the circumference of the mixing conveyor cylinder, and a spiral conveyor paddle is installed inside. One end of the spiral conveyor paddle is driven by a second drive motor. When the second drive motor starts, it drives the spiral conveyor paddle to rotate inside the mixing conveyor cylinder, propelling the raw material. During this process, smaller particles fall through the filter holes, while larger clumps are broken up by the action of the spiral conveyor paddle and the cylinder wall, achieving initial dispersion and conveying. Preferably, the bottom of the device body has an arc-shaped structure, with a main shaft installed at the bottom. One end of the main shaft is driven by a first drive motor, and two sets of blades and mixing rods in opposite directions are installed on the circumferential side of the main shaft. When the first drive motor is working, it drives the main shaft to rotate, which in turn drives the two sets of opposing blades and mixing rods to rotate synchronously. The two sets of opposing blades generate opposing forces to break up the regular flow of the raw materials and disperse clumps, while the mixing rods penetrate into the bottom accumulation area to drive the bottom raw materials to participate in the mixing, thereby achieving three-dimensional dispersion.

[0006] Preferably, a support plate is installed on the bottom surface of the device body, and a mounting base is installed on the bottom surface of the support plate; a base is provided below the device body, and a support rod is installed on the top surface of the base. The support rod is movably connected to the mounting base, so that the device body can rotate relative to the base at a certain angle; an electric push rod is also vertically installed on the top surface of the base, and a support block is provided at the output end of the electric push rod and contacts the bottom of the device body. When the electric push rod extends or retracts, it pushes the device body to sway around the support rod through the support block, which helps to mix the raw materials and improve uniformity. Preferably, a discharge hole is provided at the lower end of one end of the device body. The discharge hole is equipped with a sealing cover. After the raw materials are mixed, the sealing cover is opened and the mixed raw materials can be discharged through the discharge hole. Closing the sealing cover can ensure that the raw materials will not leak out during the mixing process. Preferably, the filter holes are provided in multiple ways, and the multiple filter holes are equally spaced on the periphery of the mixing conveyor cylinder. During the raw material conveying process, these filter holes can play a screening role, allowing raw material particles of the correct size to pass through, and at the same time, they work with the spiral conveyor to achieve the initial dispersion of the raw materials.

[0007] Preferably, the base is equipped with multiple casters at its bottom end. The casters are equidistantly installed at the four corners of the base bottom end, forming a fixed connection with the base, which facilitates the movement of the entire device and enhances the flexibility of the equipment. Preferably, a controller is installed on the outer surface of the device body. The controller is electrically connected to electrical components such as the first drive motor, the second drive motor, and the electric push rod. The controller can control the start, stop, and operating parameters of each component, thereby realizing the overall control of the batching machine's working process.

[0008] Compared with related technologies, the batching machine for ultrafine powder making provided by this utility model has the following beneficial effects: Compared with existing technologies, this ultrafine powder batching machine effectively improves the dispersion of raw materials by incorporating a mixing conveyor cylinder and a spiral conveyor paddle. Multiple filter holes on the periphery of the mixing conveyor cylinder allow for preliminary screening of agglomerated raw materials during transport. Smaller particles fall through the filter holes beforehand, while larger agglomerates are further broken down by the pushing action of the spiral conveyor paddle and the squeezing and friction against the inner wall of the mixing conveyor cylinder, reducing the amount of agglomerates entering subsequent mixing stages. Simultaneously, the continuous rotation of the spiral conveyor paddle prevents localized retention of raw materials during transport, ensuring uniform material delivery and reducing batch-to-batch variations in material dispersion. This solves the problems of raw material agglomeration and localized retention caused by the lack of a dispersion mechanism in traditional conveying structures.

[0009] Compared to existing technologies, this batching machine significantly improves dispersion in the bottom mixing stage through two sets of oppositely oriented blades and mixing rods mounted on the main shaft. The two sets of counter-rotating blades generate opposing stirring forces, disrupting the regular flow trajectory of the raw materials, effectively breaking up clumps and preventing their continued aggregation. The mixing rods penetrate deep into the bottom accumulation area, creating three-dimensional dispersion and engaging the accumulated raw materials at the bottom in the mixing process. This reduces the dispersion difference between the bottom and upper parts of the material, ensuring the uniformity of the composition of the ultrafine powder product and overcoming the shortcomings of traditional unidirectional rotating blades that can only agitate the surface and cannot achieve three-dimensional dispersion.

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] An ultrafine powder mixing machine includes a main body 1, which serves as the overall supporting foundation. A mixing conveyor cylinder 3 is fixedly installed inside the main body 1 using a welding process, forming an enclosed relationship. This installation method ensures stable operation of the mixing conveyor cylinder 3 during work. A raw material tank 2 is bolted to the top surface of the main body 1. The discharge port at the bottom of the raw material tank 2 is connected to the inlet at the top of the mixing conveyor cylinder 3 via a flange, and a sealing gasket is installed at the connection to prevent raw material leakage. This connection method allows the raw material to smoothly enter the mixing conveyor cylinder 3 from the raw material tank 2 by gravity. Multiple equally spaced filter holes 14 are drilled through the periphery of the mixing conveyor cylinder 3. The diameter of the filter holes 14 is set according to the particle size requirements of the ultrafine powder raw material. A spiral conveyor paddle 16 is installed inside the mixing conveyor cylinder 3 via a bearing seat. The blades of the spiral conveyor paddle 16 maintain a gap of 5-8 mm with the inner wall of the mixing conveyor cylinder 3. One end of the spiral conveyor paddle 16 is connected to the output shaft of a second drive motor 11 via a coupling. During installation, the mixing conveyor cylinder 3 is first fixed inside the device body 1, then the spiral conveyor paddle 16 and the second drive motor 11 are installed, and finally the raw material tank 2 is installed. When the second drive motor 11 is started, it will drive the spiral conveyor paddle 16 to rotate at a speed of 100-150 r / min inside the mixing conveyor cylinder 3. The blades push the raw material to move along the cylinder axis. During the process, smaller particles fall through the filter holes 14, and larger clumps are broken up under the pushing force of the spiral conveyor paddle 16 blades and the squeezing action of the inner wall of the mixing conveyor cylinder 3, realizing the initial dispersion and conveying of the raw material, and solving the problem of poor dispersion effect of traditional conveying structures. Example

[0015] Please refer to the following: Figure 1-4The bottom of the device body 1 is cast into an arc shape to facilitate the accumulation of raw materials towards the center. A main shaft 19 is horizontally mounted on the lower interior via a bearing seat. One end of the main shaft 19 is connected to the output shaft of a first drive motor 10 via a coupling. The first drive motor 10 is bolted to the outer wall of the device body 1. Two sets of oppositely oriented blades 17 and mixing rods 18 are keyed to the circumference of the main shaft 19. The blades 17 form a 45° angle with the main shaft 19, and the mixing rods 18 are perpendicular to the main shaft 19 and extend to the arc-shaped area at the bottom of the device body 1. The installation sequence is as follows: first, the main shaft 19 is mounted on the device body 1 via the bearing seat; then, the blades 17 and mixing rods 18 are installed; finally, the first drive motor 10 is connected. When the first drive motor 10 is working, it drives the main shaft 19 to rotate at a speed of 200-300 r / min, which in turn drives the two sets of counter-rotating blades 17 and the mixing rod 18 to rotate synchronously. When the two sets of counter-rotating blades 17 rotate, they generate opposing stirring forces, breaking the regular flow trajectory of the raw materials and effectively breaking up the agglomerated raw materials under the action of shear force. The mixing rod 18 can penetrate into the bottom accumulation area, turn the statically accumulated raw materials upward, and drive the bottom raw materials to participate in the mixing, realizing three-dimensional dispersion, which solves the problem that the traditional unidirectional blades 17 only stir the surface. Example

[0016] Please refer to the following: Figure 1-4 The device body 1 has a support plate 13 welded to its bottom surface. A mounting base 9 is bolted to the bottom surface of the support plate 13, and the mounting base 9 has a spherical groove inside. A base 7 is located below the device body 1. The base 7 is welded from structural steel, and a support rod 8 is bolted to the top surface of the base 7. The spherical joint at the top of the support rod 8 is movably connected to the spherical groove of the mounting base 9, allowing the device body 1 to rotate ±15° relative to the base 7. An electric push rod 5 is also vertically bolted to the top surface of the base 7. The support block 4 at the output end of the electric push rod 5 is made of rubber and contacts the support plate 13 at the bottom of the device body 1. During installation, the base 7 is installed first, followed by the support rod 8 and the electric push rod 5 in sequence. Finally, the device body 1 is connected to the support rod 8 via the mounting base 9. When the electric top rod 5 extends or retracts, it pushes the device body 1 to make periodic small-amplitude swaying around the support rod 8 through the support block 4. The swaying frequency is matched with the stirring frequency of the blade 17 to assist in the mixing of raw materials, further improve the mixing uniformity, and make up for the defects of insufficient mixing in traditional fixed structures. Example

[0017] Please refer to the following: Figure 1-4The device body 1 has a discharge hole 15 cut at one end below the bottom. An external threaded connector is welded to the edge of the discharge hole 15, and the inner wall of the sealing cover has an internal thread. The two are connected and matched by the thread. A sealing gasket is installed on the inner side of the sealing cover. After the raw materials are mixed, the sealing cover is rotated open, and the mixed raw materials are discharged through the discharge hole 15 under the action of gravity and stirring force. When the sealing cover is closed, tightening the thread can ensure that the raw materials will not leak out during the mixing process, realizing an effective switch between mixing and discharge. Example

[0018] Please refer to the following: Figure 1-4 The filter holes 14 are provided in multiple locations, with 2-3 filter holes per square centimeter evenly spaced on the three sides of the mixing conveyor cylinder. The filter holes 14 have an inverted conical structure, with a smaller inner diameter and a larger outer diameter, facilitating the discharge of raw material particles. During the raw material conveying process, these filter holes 14 act as a screen, allowing raw material particles that meet the particle size requirements to pass through. Simultaneously, in conjunction with the pushing and crushing action of the spiral conveyor paddle 16, they achieve initial dispersion of the raw materials, preventing larger clumps from directly entering the mixing stage and laying a good foundation for subsequent mixing processes. Example

[0019] Please refer to the following: Figure 1-4 The base 7 has multiple casters 6 evenly distributed at its four corners, bolted to its bottom. Each caster 6 is equipped with a braking device and forms a rigid connection with the base 7. During installation, the casters 6 are fixed in place after the base 7 is leveled. The casters 6 facilitate the movement and positioning of the entire device within the production workshop as needed, enhancing the equipment's flexibility and meeting the requirements of different production layouts. Example

[0020] Please refer to the following: Figure 1-4 The controller 12 is bolted to the outer surface of the device body 1. The circuit board inside the controller 12 is electrically connected to electrical components such as the first drive motor 10, the second drive motor 11, and the electric push rod 5 via wires. The wires are protected by conduit. During installation, the wires are laid first, and then the controller 12 is fixed. The operator can set operating parameters such as the speed of the first drive motor 10 and the second drive motor 11, and the sway amplitude and frequency of the electric push rod 5 through the buttons and display screen on the controller 12, so as to realize the overall control of the batching machine's working process, ensure that the equipment operates stably according to the preset program, and improve the automation level of production.

[0021] It should be noted that the control circuit of controller 12 can be implemented by simple programming by those skilled in the art, and is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0022] The working principle of the ultrafine powder mixing machine provided by this utility model is as follows: The raw materials first enter the mixing conveyor cylinder 3 from the raw material tank 2. The second drive motor 11 starts, driving the spiral conveyor 16 to rotate. The spiral conveyor 16 pushes the raw materials to move inside the mixing conveyor cylinder 3. During the movement, smaller raw material particles fall through multiple equidistant filter holes 14 on the side of the mixing conveyor cylinder 3 to the lower part of the device body 1. Larger agglomerated raw materials are broken up by the pushing action of the spiral conveyor 16 and the friction and compression action of the inner wall of the mixing conveyor cylinder 3. The broken particles also fall through the filter holes 14, realizing the initial dispersion and screening of the raw materials in the conveying stage. The raw materials falling into the lower part of the device body 1 are driven by the first drive motor 10 to rotate the main shaft 19. The main shaft 19 drives two sets of blades 17 and mixing rods 18 with opposite installation directions to rotate. The two sets of opposing blades 17 generate opposite stirring forces, breaking the regular flow trajectory of the raw materials and further breaking up the clumps. The mixing rods 18 penetrate deep into the bottom accumulation area to perform three-dimensional stirring of the raw materials, so that the raw materials accumulated at the bottom are fully mixed with the raw materials at the top, avoiding long-term static accumulation of the raw materials at the bottom. Furthermore, during the mixing process, the electric push rod 5 can extend and retract to move the support block 4 up and down. Since the support rod 8 is movably connected to the mounting base 9, the device body 1 can sway slightly around the support rod 8 to assist in mixing the raw materials and improve the mixing uniformity. After mixing is completed, the sealing cover of the discharge hole 15 is opened, and the mixed raw materials are discharged from the discharge hole 15.
