Description

Technical Field

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

[0002] In granulation production lines, uniform mixing of raw materials is a key process to ensure the quality of the finished product. Currently, commonly used raw material mixing devices mostly employ a single stirring paddle or blade to rotate and stir within a tank.

[0003] However, existing technologies have the following shortcomings in practical applications: First, the stirring structure is simple, and mixing dead zones are easily formed near the inner wall and bottom corners of the tank, resulting in uneven local raw material ratios and affecting granulation quality; Second, for raw materials that are prone to agglomeration or have high viscosity, traditional stirring methods are difficult to effectively disperse them, resulting in low mixing efficiency and long mixing time; Third, there is a lack of auxiliary mixing methods, and mechanical stirring alone cannot disturb the raw materials in multiple dimensions, making it difficult to meet the requirements of high-precision production in terms of mixing uniformity; Fourth, existing devices mostly use manual or semi-automatic control, and the coordination of various actuators is poor, making it impossible to automatically adjust stirring and airflow parameters according to the mixing stage.

[0004] Therefore, how to design a raw material mixing device for a granulation production line that can achieve multi-stage three-dimensional mixing, eliminate mixing dead zones, have airflow-assisted mixing function, and have a high degree of automation has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to provide a raw material mixing device for a granulation production line, which has the advantages of multi-stage three-dimensional stirring, magnetic-assisted mixing, airflow disturbance to promote uniform mixing and high degree of automation, thus solving the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A raw material mixing device for a granulation production line includes a mixing tank, a bearing assembly fixedly connected to the outer peripheral wall of the mixing tank, a feeding assembly fixedly connected to the upper part of the inner wall of the mixing tank, a blowing assembly fixedly connected to the middle part of the side wall of the mixing tank, an air-inflating assembly fixedly connected to the side wall of the mixing tank, a first conical cylinder fixedly connected to the lower end of the mixing tank, a feeding mechanism disposed at the lower end of the first conical cylinder, a top cover fixedly connected to the upper part of the inner wall of the mixing tank, a motor fixedly connected to the upper end of the top cover, a rotating rod fixedly connected to the lower end of the motor output shaft, and a plurality of first stirring blocks fixedly connected to the upper part of the outer peripheral wall of the rotating rod. The system comprises: multiple stirring plates fixedly connected to the middle of the outer peripheral wall of the rotating rod; an annular fixed box fixedly connected to the lower part of the inner wall of the mixing tank; a magnetic stirring assembly magnetically linked to the rotating rod; a second bracket fixedly connected to the inner wall of the mixing tank; a linear bearing fixedly connected to the second bracket; a fixed cylinder fixedly connected to the lowest part of the outer peripheral wall of the rotating rod; a second stirring block fixedly connected to the outer peripheral wall of the fixed cylinder; a fixed plate fixedly connected to the upper part of the inner wall of the mixing tank; multiple discharge cylinders fixedly connected through the fixed plate to the lower end; a fifth valve body disposed on the discharge cylinder; and a controller disposed on the blowing assembly. The outer peripheral wall of the rotating rod is rotatably disposed on the inner wall of the linear bearing; the second stirring block is located inside the first conical cylinder; the first stirring block is located above the fixed plate, and the stirring plates are located below the fixed plate; the controller is electrically connected to the blowing assembly, the air filling assembly, the motor, the feeding mechanism, and the fifth valve body.

[0007] Preferably, the support assembly includes four fixing blocks fixedly connected to the outer peripheral wall of the mixing tank and support legs fixedly connected to the lower end of each fixing block.

[0008] It is worth noting that by setting up four sets of rectangularly distributed fixing blocks and support legs, the mixing tank is stably supported on the mounting base. The four support legs jointly bear the entire weight of the mixing tank and the raw materials inside, which has higher anti-tipping stability compared to the three-leg structure, and can effectively prevent the device from shaking or displacing when the motor is running at high speed or when there is airflow disturbance.

[0009] Preferably, the feeding mechanism includes a discharge pipe fixedly connected to the lower end of the first conical cylinder and a first valve body disposed on the discharge pipe.

[0010] It is worth noting that the feeding mechanism adopts a conical cylinder design in conjunction with the discharge pipe and the first valve body. The concave structure of the conical cylinder causes the mixed raw materials to automatically converge towards the center under gravity, preventing raw materials from remaining at the bottom corners of the tank. The first valve body, as the on / off actuator, can be precisely controlled by the controller to adjust the opening angle and duration, achieving quantitative or continuous discharge. Compared with traditional flap valves or slide gate valves, this structure has better sealing performance, eliminates the risk of material jamming, and the valve body is directly connected to the discharge pipe, reducing secondary dust generation.

[0011] Preferably, the upper end of the annular fixing box is provided with a groove, and the lower end of the annular fixing box is provided with multiple discharge holes that communicate with the groove.

[0012] It is worth noting that the annular fixed box's trough serves as a collection and distribution chamber for airflow, with multiple discharge holes evenly distributed along the ring. This allows high-pressure gas supplied by the blowing and inflation components to be simultaneously ejected upwards or laterally from multiple directions at the bottom of the tank, forming a three-dimensional cross-flow network within the tank. This structure overcomes the limitations of traditional single air inlets, which can only create directional airflow and are prone to flow deviation. It ensures that the raw material at the bottom of the tank is uniformly disturbed from all directions, resulting in more thorough fluidization and complete elimination of mixing dead zones. Simultaneously, the small-diameter design of the discharge holes prevents large particles from backflowing into the trough, ensuring long-term unobstructed airflow channels.

[0013] Preferably, the blowing assembly includes a support block disposed outside the mixing tank, an axial flow fan fixedly connected to the upper end of the support block, a gas collection hood fixedly connected to the air outlet of the axial flow fan, and a blowing pipe fixedly connected to the air outlet of the gas collection hood; the air outlet of the blowing pipe passes through the outer peripheral wall of the mixing tank and extends into the interior of the annular fixed box, and communicates with the tank body.

[0014] It is worth noting that the blowing assembly uses an axial flow fan as its air source, characterized by large air volume and moderate air pressure, making it suitable for large-area airflow delivery. The air collection hood gathers the diffused airflow from the fan outlet and guides it to the blowing duct, reducing energy loss. The blowing duct extends directly into the tank, allowing the airflow to reach the annular distribution chamber directly, avoiding pressure attenuation caused by long-distance pipeline delivery.

[0015] Preferably, the inflation assembly includes a base block disposed outside the mixing tank, an air pump fixedly connected to the upper end of the base block, an air outlet pipe fixedly connected to the air outlet end of the air pump, a fixed pipe fixedly connected through the middle of the side wall of the mixing tank, a second valve body disposed on the fixed pipe, an air inlet pipe fixedly connected through the side wall of the air outlet pipe, and a third valve body disposed on the air inlet pipe; the central axis of the fixed pipe and the central axis of the air blowing pipe are perpendicularly intersecting each other; the air outlet end of the fixed pipe passes through the outer peripheral wall of the mixing tank and the outer peripheral wall of the annular fixed box and extends into the interior of the tank, and communicates with the tank; the air outlet end of the air outlet pipe is also fixedly connected to and communicates with the air inlet end of the fixed pipe.

[0016] It is worth noting that the inflation component uses an air pump to provide a high-pressure, low-flow air source, complementing the blowing component. The fixed pipe and the blowing pipe intersect perpendicularly, causing the two airflows to converge within the tank, generating strong vortex turbulence, which significantly enhances the airflow's shearing and dispersing capabilities on the raw materials. The second valve controls the gas flow through the fixed pipe, and the third valve controls the independent air supply through the inlet pipe. This dual-path parallel and directional airflow design allows for flexible switching based on the characteristics of the raw materials: for easily agglomerated materials, both airflow paths are activated simultaneously to create high-intensity turbulence and disperse the agglomerates; for materials with good flowability, only the blowing component is activated to avoid excessive energy consumption.

[0017] Preferably, the air outlet of the air inlet pipe penetrates the outer peripheral wall of the mixing tank and extends to the inner wall of the mixing tank, and is positioned directly opposite the second bracket.

[0018] It is worth noting that the air outlet of the air inlet pipe is directly opposite the second bracket, on which a linear bearing is mounted. During the mixing process, raw material powder or fine particles can easily adhere to the sliding contact surface of the linear bearing, increasing the frictional resistance of the rotor and even causing jamming. By directly spraying high-pressure airflow into this area, the accumulated material around the bearing can be effectively blown away, forming an air curtain to protect against dust intrusion into the sliding gap.

[0019] Preferably, the feeding assembly includes a first bracket fixedly connected to the upper part of the inner wall of the mixing tank, a feed pipe fixedly connected to the first bracket through the middle, a fourth valve body disposed on the feed pipe, a second conical cylinder fixedly connected to the upper end of the feed pipe, and a temporary storage cylinder fixedly connected to the upper end of the second conical cylinder.

[0020] It is worth noting that the feeding assembly adopts a three-stage buffer conveying structure of a temporary storage cylinder, a conical cylinder, and a feed pipe. The temporary storage cylinder can hold all the raw materials in a single batch, enabling continuous production without repeated feeding after a single hoisting. The constriction design of the second conical cylinder allows the raw materials to naturally flow into the feed pipe, avoiding bridging and blockage. The fourth valve body is controlled by a controller and can be opened intermittently or continuously according to a preset program, realizing automated quantitative feeding.

[0021] Preferably, the magnetic stirring assembly includes a first magnet block slidably placed on the bottom surface of the inner wall of the tank, a first inner ring and a second inner ring fixedly connected to the inner wall of the tank, a plastic box fixedly connected to the lower part of the outer peripheral wall of the rotating rod, and a second magnet block fixedly connected inside the plastic box; the inner diameter of the first inner ring is larger than the outer diameter of the second inner ring, and an annular gap is formed between the first inner ring and the second inner ring, with the first inner ring located on the outer periphery of the second inner ring, and the lower end face of the first inner ring being flush with the lower end face of the second inner ring; the upper end of the first magnet block is simultaneously in contact with the lower end of both the first inner ring and the lower end of the second inner ring; the second magnet block is at the same height as the first magnet block, and when the rotating rod rotates, the second magnet block drives the first magnet block to move within the tank through magnetic attraction.

[0022] It is worth noting that this magnetic stirring assembly achieves non-contact power transmission. There is no mechanical connection between the second magnet on the rotating rod and the first magnet inside the tank; the drive relies entirely on magnetic coupling. Because there is no physical contact between the rotating rod and the magnet, the problems of leakage and wear inherent in traditional mechanical seals are completely eliminated, making it particularly suitable for mixing raw materials containing fine powders. The annular gap formed by the first and second inner rings defines the movement trajectory of the first magnet, ensuring it always moves in a circular motion at the bottom of the tank. This continuously pushes the raw material deposited around the discharge port towards the discharge port area, allowing it to be re-introduced into the mixing body by the airflow.

[0023] Preferably, the controller is electrically connected to the axial flow fan, the air pump, the motor, the first valve body, the second valve body, the third valve body, the fourth valve body, and the fifth valve body, respectively.

[0024] It is worth noting that the controller, as the central control unit of the entire device, integrates the timing control and logical linkage functions of each execution component.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model forms a three-dimensional mixing structure of upper, middle and lower levels by setting a first stirring block above the fixed plate, a stirring plate below the fixed plate and a second stirring block inside the first conical cylinder. This solves the problems of multiple mixing dead zones and uneven mixing in existing devices and realizes comprehensive stirring of raw materials at all height levels in the mixing tank. 2. This utility model, by setting up a magnetic stirring component that is magnetically linked with the rotating rod, uses the second magnet to drive the first magnet to move in the groove of the annular fixed box, thereby assisting in disturbing the raw materials deposited at the bottom of the fixed box, solving the problem that the raw materials at the bottom are easy to accumulate and difficult to participate in mixing, and further eliminating mixing dead zones. 3. This utility model solves the problems of low mixing efficiency and difficulty in breaking up clumps of raw materials by setting up a blowing component to blow air into the fixed box and an air filling component to fill the mixing tank, and forming airflow disturbance with the discharge hole at the bottom of the fixed box. This causes the raw materials to tumble and convection under the action of airflow, which significantly improves the mixing uniformity and efficiency of traditional single mechanical stirring. 4. This utility model achieves fully automated control of the entire process of feeding, mixing, discharging, and airflow assistance through the electrical connection of the controller with the motor, valve body, axial flow fan, and air pump. It solves the problems of excessive manual operation and poor coordination in existing equipment, and improves the level of automation and consistency of production. Attached Figure Description

[0039] In this embodiment, specifically, the magnetic stirring assembly includes a first magnet 161 slidably placed on the bottom surface of the inner wall of the tank 16, a first inner ring 17 and a second inner ring 18 fixedly connected to the inner wall of the tank 16, a plastic box 23 fixedly connected to the lower part of the outer peripheral wall of the rotating rod 12, and a second magnet 24 fixedly connected inside the plastic box 23; the inner diameter of the first inner ring 17 is larger than the outer diameter of the second inner ring 18, and an annular gap is formed between the first inner ring 17 and the second inner ring 18, and the first inner ring 17 is located on the outer periphery of the second inner ring 18, and the lower end face of the first inner ring 17 is flush with the lower end face of the second inner ring 18; the upper end of the first magnet 161 is simultaneously attached to the lower end of the first inner ring 17 and the lower end of the second inner ring 18; the second magnet 24 is at the same height as the first magnet 161, and when the rotating rod 12 rotates, the second magnet 24 drives the first magnet 161 to move within the tank 16 through magnetic attraction.

[0040] In this embodiment, the controller 8 is specifically electrically connected to the axial flow fan 702, the air pump 602, the motor 11, the first valve body 5, the second valve body 605, the third valve body 607, the fourth valve body 903, and the fifth valve body 27.

[0041] Working principle: During use, the operator sets the speed of motor 11, the air volume of axial fan 702, the pressure of air pump 602, and the opening and closing sequence of each valve through controller 8. First, the fourth valve 903 is opened, and the raw material falls from the temporary storage cylinder 905 through the second conical cylinder 904 and the feed pipe 902 into the area above the fixed plate 25 in the mixing tank 1. The motor 11 is started, and the rotating rod 12 drives the first stirring block 13 to rotate, which initially disperses and premixes the raw material. The premixed raw material falls through the discharge cylinder 26 (the fifth valve 27 is opened) into the main mixing area of ​​the mixing tank 1 below the fixed plate 25. The stirring plate 14 performs radial stirring of the raw material. At the same time, the fixed cylinder 21 below the rotating rod 12 drives the second stirring block 22 to rotate in the first conical cylinder 3 to prevent the raw material from accumulating in the conical cylinder. During the mixing process, the controller 8 starts the axial flow fan 702. The airflow enters the tank 16 of the annular fixed box 15 through the air collection hood 703 and the air blowing pipe 704, and is sprayed upward from the discharge hole 19, which generates airflow disturbance on the raw material at the bottom of the tank, causing the raw material to roll upward. At the same time, the air pump 602 is started, and high-pressure gas is sent to the fixed pipe 604 and the air inlet pipe 606 through the air outlet pipe 603 respectively. The fixed pipe 604 sends the gas into the tank 16 and merges with the air blowing airflow to form a rotating cyclone. The air inlet pipe 606 sprays the gas directly towards the vicinity of the second support 20, impacting and dispersing the raw material in the middle area. When the rotating rod 12 rotates, the second magnet 24 inside the plastic box 23 rotates accordingly. Due to the magnetic coupling effect, the first magnet 161 inside the tank 16 is driven to move along the annular gap between the first inner ring 17 and the second inner ring 18, continuously scraping the bottom surface of the tank 16, pushing the raw material deposited at the bottom towards the discharge hole 19 area, so that it is carried back into the mixing area by the airflow. After mixing is completed, the controller 8 shuts off the motor 11, axial flow fan 702 and air pump 602, and opens the first valve body 5. The uniformly mixed raw material is discharged through the first conical cylinder 3 and the discharge pipe 4 and enters the next granulation process.
