Description

Technical Field

[0001] This invention relates to the field of stirred mill technology, specifically to a high-efficiency stirred mill with an auxiliary stirring component. Background Technology

[0002] A high-efficiency stirred mill is a key piece of equipment that uses a mechanical stirring device to drive grinding media to crush and mix materials. It is widely used in mining, chemical, building materials and other fields. Its core purpose is to achieve ultra-fine crushing and highly uniform mixing of material particles by strengthening the stirring intensity and material circulation, thereby significantly improving production efficiency and the quality of the final product.

[0003] However, existing stirred mills still have significant shortcomings in practical applications. First, the single stirring structure easily creates dead zones in the chamber, leading to uneven material mixing and affecting the consistency of product quality. Second, materials tend to adhere to the inner wall of the mixing chamber, causing waste and increasing the burden of cleaning and maintenance. In addition, conventional agitators often have difficulty effectively stirring materials that have settled at the bottom of the chamber, which can easily lead to material caking or blockage of the discharge port, thereby reducing the continuous working efficiency and reliability of the entire machine and restricting further improvement in production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency stirred mill with an auxiliary stirring component to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency stirring mill with auxiliary stirring components, including a base, a set of stirring chambers provided at the top center of the base, a set of feed inlets provided at the front and rear bottom ends of the stirring chambers, a set of discharge outlets provided at the left and right sides near the top end of the stirring chambers, and a set of drive motors connected to the top center of the stirring chambers, the bottom end of the drive shaft of the drive motors extending into the stirring chambers and connected to a stirring mechanism.

[0006] The stirring mechanism includes a stirring rod, an auxiliary stirring mechanism one, a spiral belt, and an auxiliary stirring mechanism two. The bottom end of the drive motor drive shaft extends to the top of the stirring chamber and is connected to a set of stirring rods. An auxiliary stirring mechanism one is provided at the top of the outer side of the stirring rods. An auxiliary stirring mechanism one is provided at the bottom of the auxiliary stirring mechanism one. An auxiliary stirring mechanism two is provided at the bottom of the spiral belt.

[0007] By adopting the above technical solution, continuous feeding and discharging of materials and efficient mixing can be achieved. Among them, the auxiliary mixing mechanism one, the spiral belt and the auxiliary mixing mechanism two are arranged from top to bottom on the outside of the mixing rod to form a layered design, which can cover different areas in the mixing chamber, improve the comprehensiveness and uniformity of mixing, avoid mixing dead corners, and thus effectively improve grinding efficiency and product quality.

[0008] Preferably, the auxiliary stirring mechanism includes a turntable, a connecting arm, a cleaning scraper, and stirring blades. A set of turntables is provided on the outer side of the stirring rod near the top. A set of cleaning scrapers is connected to both the left and right ends of the turntable through the connecting arm. The turntable has no less than two sets of stirring blades on both the upper and lower surfaces.

[0009] By adopting the above technical solution, the cleaning scraper can scrape off the material adhering to the inner wall of the mixing chamber during the mixing process, reduce sedimentation, achieve the cleaning function of the inner wall of the mixing chamber, prevent material adhesion, reduce maintenance needs, extend the service life of the equipment, and the mixing blades can enhance the mixing effect of materials.

[0010] Preferably, the auxiliary stirring mechanism two includes a rotating chamber, a rotating shaft, a connecting frame, a connecting ring, a worm gear, a stirring arm, a worm wheel, and a fixed tube. The bottom end of the stirring rod is connected to a set of rotating chambers. A set of rotating shafts is provided in the middle of the rotating chamber. A set of connecting frames is provided on the outer side of the rotating shafts near the top surface of the rotating chamber. A set of connecting rings is connected to both ends of the connecting frames away from the rotating shafts, and a set of worm gears is connected through the two sets of connecting rings. One end of the worm gear extends through to the outer side of the rotating chamber and is connected to a set of stirring arms. A set of worm wheels is provided on the outer side of the rotating shafts near the bottom surface of the rotating chamber. A set of fixed tubes is provided at the bottom middle of the worm wheels. The bottom end of the fixed tubes passes through the rotating chamber and connects to the middle of the bottom surface of the stirring chamber.

[0011] By adopting the above technical solution, the worm and worm wheel are meshed and connected, which can drive the stirring arm to rotate. This allows the stirring arm to revolve around the stirring rod while rotating on its own axis perpendicular to the horizontal plane around the worm. This not only improves the stability of the transmission and the stirring efficiency, but also enhances the stirring and mixing of the materials at the bottom of the stirring chamber, significantly improving the stirring efficiency.

[0012] Preferably, the rotating shaft is rotatably connected to the worm gear, and the bottom end of the rotating shaft extends through into the fixed cylinder.

[0013] Preferably, the worm gear is fixedly connected to the bottom surface of the mixing chamber via a fixed cylinder, and the bottom middle of the rotating chamber is rotatably connected to the fixed cylinder.

[0014] By adopting the above technical solution, the worm gear is fixed and the rotating chamber is rotated, thereby driving the worm and stirring arm to rotate, improving the accuracy and efficiency of the transmission, and avoiding interference between components.

[0015] Preferably, the connecting frame has a "V" shaped structure.

[0016] Preferably, the worm meshes with the worm wheel, and the threaded portion of the worm is located between two sets of connecting rings.

[0017] By adopting the above technical solution, the two sets of connecting rings can cooperate with the thread to restrict the movement of the worm, ensuring the accuracy and continuity of the transmission, preventing disengagement or slippage, and improving the driving efficiency and reliability of the stirring arm.

[0018] Preferably, the stirring blade is an irregular blade, and the surface of the stirring blade is provided with micro-grooves.

[0019] By adopting the above technical solution, the irregularly shaped stirring blades can increase the contact area between the blades and the material, effectively improve the friction and shear force, and enhance the dispersion effect on the material through micro-grooves, thus preventing agglomeration.

[0020] Preferably, the side of the cleaning scraper away from the connecting arm contacts the inner wall of the mixing chamber.

[0021] By adopting the above technical solution, it is easy to scrape off the material adhering to the inner wall of the mixing chamber, prevent material accumulation and clumping, effectively keep the mixing chamber clean, and reduce the intensity of subsequent cleaning of the mixing chamber.

[0022] Preferably, there is a space between the bottom surface of the rotating chamber and the bottom surface of the mixing chamber.

[0023] By adopting the above technical solution, the stirring arm will not collide with the bottom surface of the stirring chamber when it rotates, avoiding mutual interference between components. It can also provide an additional flow channel for materials, preventing blockage of materials at the bottom, promoting full mixing of materials, and improving overall stirring efficiency.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention forms a layered mixing structure by using an auxiliary mixing mechanism one, a spiral belt, and an auxiliary mixing mechanism two located on the outside of the mixing rod. This structure can cover different areas within the mixing chamber, achieving comprehensive and uniform mixing of materials. It effectively avoids the mixing dead zones commonly found in traditional mixers, ensuring that materials are fully mixed during the grinding process. This significantly improves grinding efficiency and product quality. Furthermore, the spiral belt plays a vertical conveying role during the mixing process, promoting the exchange of materials between the upper and lower layers, enhancing the continuity and uniformity of the mixing. It also optimizes the flow path of materials, making the mixing process more efficient and energy-saving. This invention is suitable for processing high-viscosity or easily agglomerated materials, improving the applicability and reliability of the equipment.

[0026] 2. This invention achieves internal wall cleaning and efficient mixing during the mixing process through the cleaning scraper and mixing blades set in the auxiliary mixing mechanism. The cleaning scraper contacts the inner wall of the mixing chamber and can scrape off the attached material in time during the mixing process, preventing material accumulation and agglomeration, reducing maintenance frequency and equipment downtime, and extending the service life of the equipment. At the same time, the micro-grooves opened on the surface of the irregularly shaped mixing blades can not only increase the contact area and shear force with the material, effectively break up agglomerated materials, but also improve the mixing effect and dispersion uniformity of the material. It not only keeps the inside of the mixing chamber clean, but also improves the material flowability by enhancing local turbulence, thereby improving the overall mixing efficiency and product quality consistency.

[0027] 3. This invention, through the worm gear, worm wheel, and stirring arm set in the auxiliary stirring mechanism two, realizes the combined revolution and rotation of the stirring arm, significantly enhancing the stirring effect on the bottom material. The meshing transmission of the worm gear and worm wheel is stable and reliable, driving the stirring arm to revolve around the stirring rod while rotating around its own axis, increasing the stirring intensity and shearing effect on the material, avoiding the deposition and blockage of the bottom material in the stirring chamber. The fixed cylinder ensures the fixation of the transmission components and the smoothness of movement, improving the accuracy and efficiency of the transmission, reducing the risk of component interference, thereby improving the reliability and service life of the equipment in high-efficiency grinding applications.

Detailed Implementation

[0035] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0036] Please see Figures 1-2 This invention provides a high-efficiency stirred mill with auxiliary stirring components, including a base 1. A set of stirring chambers 2 are fixedly installed at the top center of the base 1. A set of feed inlets 3 are connected to the front, rear, and bottom ends of the stirring chambers 2. Materials can be pumped into the stirring chambers 2 through the feed inlets 3. A set of discharge outlets 4 are installed on the left and right sides of the stirring chambers 2 near the top. After the materials are stirred, they overflow from the discharge outlets 4 to achieve discharge. A set of drive motors 5 are installed at the top center of the stirring chambers 2. The bottom end of the drive shaft of the drive motors 5 extends into the stirring chambers 2 and is connected to a stirring mechanism 6. The stirring mechanism 6 includes a stirring rod 61, an auxiliary stirring mechanism 62, a spiral belt 63, and an auxiliary stirring mechanism 64. The bottom end of the drive shaft of the drive motors 5 extends into the top of the stirring chambers 2 and is connected to a set of stirring rods 61, which can drive the stirring rods 61 to rotate. A set of auxiliary stirring mechanism 62 is provided at the top outer side of the stirring rods 61. A set of spiral belts 63 are installed at the bottom end of the auxiliary stirring mechanism 62, and a set of auxiliary stirring mechanisms 64 is provided at the bottom end of the spiral belts 63.

[0037] Specifically, it can realize continuous feeding and discharging of materials and efficient mixing. The auxiliary mixing mechanism 1 62, the spiral belt 63 and the auxiliary mixing mechanism 2 64 are arranged from top to bottom on the outside of the mixing rod 61 to form a layered design, which can cover different areas in the mixing chamber 2, improve the comprehensiveness and uniformity of mixing, avoid mixing dead corners, and thus effectively improve grinding efficiency and product quality.

[0038] Please see Figures 2-3The auxiliary stirring mechanism 62 includes a turntable 621, a connecting arm 622, a cleaning scraper 623, and stirring blades 624. A set of turntables 621 is installed near the top of the outer side of the stirring rod 61. A set of cleaning scrapers 623 is connected to both ends of the turntable 621 through the connecting arm 622. The side of the cleaning scraper 623 away from the connecting arm 622 contacts the inner wall of the stirring chamber 2, which facilitates the scraping off of the material adhering to the inner wall of the stirring chamber 2, preventing material accumulation and agglomeration, effectively keeping the stirring chamber 2 clean, and reducing the intensity of subsequent cleaning of the stirring chamber 2. The turntable 621 is equipped with no less than two sets of stirring blades 624 on both the upper and lower surfaces. The stirring blades 624 are irregular blades, and the surface of the stirring blades 624 is provided with micro-grooves. The irregular shape of the stirring blades 624 can increase the contact area with the material, effectively improve the friction and shear force, and enhance the dispersion effect on the material through the micro-grooves, which can prevent agglomeration.

[0039] Specifically, the cleaning scraper 623 can scrape off the material adhering to the inner wall of the mixing chamber 2 during the mixing process, reduce sedimentation, achieve the cleaning function of the inner wall of the mixing chamber 2, prevent material adhesion, reduce maintenance needs, and extend the service life of the equipment. The mixing blade 624 can enhance the mixing effect of the material.

[0040] Please see Figures 4-6The auxiliary stirring mechanism 64 includes a rotating chamber 641, a rotating shaft 642, a connecting frame 643, a connecting ring 644, a worm gear 645, a stirring arm 646, a worm wheel 647, and a fixed cylinder 648. A set of rotating chambers 641 is fixedly connected to the bottom end of the stirring rod 61. Rotation of the stirring rod 61 drives the rotating chambers 641 to rotate synchronously. A set of rotating shafts 642 is installed in the middle of the rotating chamber 641. A set of connecting frames 643 is located on the outer side of the rotating shafts 642 near the inner top surface of the rotating chamber 641. The connecting frame 643 has a "V" shaped structure. A set of connecting rings 644 are connected to both ends of the connecting frame 643 away from the rotating shafts 642, and the connection is achieved through the two sets of connecting rings 645. A set of worm gears 645 is connected to 44, and the worm gears 645 are rotatably connected to two sets of connecting rings 644. The worm gears 645 can rotate within the two sets of connecting rings 644, and the threaded portion of the worm gears 645 is located between the two sets of connecting rings 644. The two sets of connecting rings 644 can cooperate with the threads to restrict the movement of the worm gears 645, ensuring the accuracy and continuity of transmission, preventing disengagement or slippage, and improving the driving efficiency and reliability of the stirring arms 646. One end of the worm gears 645 extends through to the outside of the rotating chamber 641 and is connected to a set of stirring arms 646. The rotation of the worm gears 645 drives the stirring arms 646 to rotate around their own axis, effectively improving the stirring effect and shearing action on the materials. The rotating shaft... A set of worm gears 647 is rotatably connected to the outer side of the rotating chamber 642 near the bottom surface of the inner side of the rotating chamber 641. A set of fixed tubes 648 is fixedly connected to the bottom center of the worm gears 647. The bottom end of the fixed tubes 648 passes through the rotating chamber 641 and is fixedly connected to the middle of the inner bottom surface of the stirring chamber 2. The bottom end of the rotating shaft 642 extends through and into the fixed tubes 648, which can prevent the rotating shaft 642 from deviating or tilting during rotation. The bottom center of the rotating chamber 641 is rotatably connected to the fixed tubes 648. When the rotating chamber 641, rotating shaft 642, connecting frame 643, connecting ring 644, worm gear 645 and stirring arm 646 rotate, the worm gears 647 and the fixed tubes 648 remain stationary. Unlike other components, this design avoids interference between parts. Specifically, the worm 645 meshes with the worm wheel 647. When the rotating shaft 642 rotates, the connecting frame 643 and connecting ring 644 drive the worm 645 to rotate. The worm 645 and the worm wheel 647 are threadedly engaged on the outside, thus enabling the worm 645 and the stirring arm 646 to rotate independently. Furthermore, there is space between the bottom surface of the rotating chamber 641 and the inner bottom surface of the stirring chamber 2, preventing the stirring arm 646 from colliding with the inner bottom surface of the stirring chamber 2 during rotation. This avoids interference between components and provides an additional flow channel for materials, preventing blockage at the bottom, promoting thorough mixing, and improving overall stirring efficiency.

[0041] Specifically, the worm 645 and worm wheel 647 are meshed and connected, which can drive the stirring arm 646 to rotate. This allows the stirring arm 646 to revolve around the stirring rod 61 while rotating on its own axis perpendicular to the horizontal plane around the worm 645. This not only improves the stability of the transmission and the stirring efficiency, but also enhances the stirring and mixing of the materials at the bottom of the stirring chamber 2, significantly improving the stirring efficiency.

[0042] This invention provides a high-efficiency stirred mill with auxiliary stirring components. Through auxiliary stirring mechanism 62, spiral belt 63, and auxiliary stirring mechanism 64 located outside the stirring rod 61, a layered stirring structure is formed, covering different areas within the stirring chamber 2. This achieves comprehensive and uniform mixing of materials, effectively avoiding the dead zones common in traditional mixers, ensuring thorough mixing during the grinding process, thus significantly improving grinding efficiency and product quality. The spiral belt 63 acts as a vertical conveyor during mixing, promoting the exchange of materials between upper and lower layers, enhancing the continuity and uniformity of mixing, and optimizing the material flow path, making the mixing process more efficient and energy-saving. It is suitable for processing high-viscosity or easily agglomerated materials, improving the applicability and reliability of the equipment. The cleaning scraper 623 and stirring blades 624 located in auxiliary stirring mechanism 62 achieve internal wall cleaning and efficient mixing during the mixing process. The cleaning scraper 623 contacts the inner wall of the stirring chamber 2, promptly scraping off adhering materials during mixing, preventing material accumulation and agglomeration, reducing maintenance frequency and equipment downtime, and extending the grinding time. The equipment's service life is extended. Meanwhile, microgrooves are created on the surface of the irregularly shaped stirring blades 624, which not only increase the contact area and shear force with the material, effectively breaking up agglomerated materials, but also improve the mixing effect and dispersion uniformity of the material. This not only maintains the cleanliness of the mixing chamber 2, but also improves material flowability by enhancing local turbulence, thereby improving overall mixing efficiency and product quality consistency. Through the worm gear 645, worm wheel 647, and stirring arm 646 set in the auxiliary stirring mechanism 64, the revolution and rotation of the stirring arm 646 are realized. The combined rotational motion significantly enhances the mixing effect on the bottom material. The meshing transmission between the worm gear 645 and the worm wheel 647 is stable and reliable, driving the mixing arm 646 to revolve around the mixing rod 61 while rotating on its own axis. This increases the mixing intensity and shearing effect on the material, preventing the sedimentation and blockage of the bottom material in the mixing chamber 2. The fixed cylinder 648 ensures the fixation of the transmission components and the smoothness of the movement, improving the accuracy and efficiency of the transmission, reducing the risk of interference between components, and thus enhancing the reliability and service life of the equipment in high-efficiency grinding applications.
