Description

Technical Field

[0001] This invention relates to the technical field of grinding equipment, and in particular to an inorganic mineral ultrafine grinding device. Background Technology

[0002] Inorganic minerals are natural inorganic compounds or elements produced by geological processes. They have fixed chemical compositions and specific crystal structures. Inorganic minerals generally exist in the form of crystals, powders, layers, and fibers, and are widely used in construction, metallurgy, electronics industry, coatings and other fields.

[0003] Ultrafine grinding of inorganic minerals can significantly alter the properties of materials, including enhancing reactivity, improving dispersibility and flowability, increasing adsorption capacity and catalytic efficiency. For example, magnesium hydroxide, as a flame retardant, exhibits better flame retardant, smoke suppression, and filling effects after ultrafine grinding, especially in the rubber and plastics industries.

[0004] Ultrafine grinding of inorganic minerals is generally achieved through methods such as air jet mills or stirred mills. This processing method mainly achieves the pulverization effect through the mutual collision and friction of the raw materials. However, since the impact intensity, impact angle, and speed of the raw materials cannot be controlled, the pulverization effect is also uncontrollable. During pulverization, some raw materials cannot be completely pulverized, resulting in poor pulverization effect, or repeated pulverization is required to further reduce the particle size of the raw materials. Furthermore, screening structures such as sieves are required to intercept large particles of raw materials. Therefore, it cannot meet people's needs in terms of both structural complexity and raw material pulverization effect. Summary of the Invention

[0009] Furthermore, a top plate is provided on the end face of the spherical crown.

[0014] A power unit is installed inside the vertical barrel. The power unit is connected to the positioning ball and is used to provide power for the movement of the spherical crown.

[0015] Furthermore, the power unit includes a power box located at the axis of the vertical barrel. The power box is fixedly connected to the inner wall of the vertical barrel. A first turntable is rotatably provided at the bottom of the power box. The top surface of the first turntable extends into the power box. A connecting sleeve is eccentrically fixed on the first turntable, and the axis of the connecting sleeve is inclined relative to the axis of the first turntable.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0034] like Figures 1 to 4 As shown, the inorganic mineral ultrafine grinding device of the present invention includes a vertical barrel 1 with an opening at the top, through which raw materials are introduced into the barrel 1. The bottom of the barrel 1 is provided with a first spherical surface 2 and a second spherical surface 3 located inside the first spherical surface 2. A spherical crown 5 is disposed inside the second spherical surface 3, and the second spherical surface 3 and the spherical crown 5 cooperate to grind the raw materials. The first spherical surface 2 is used to transfer the raw materials between the second spherical surface 3 and the spherical crown 5. The bottom of the second spherical surface 3 is connected to a discharge pipe 4 for discharging the ground raw materials.

[0035] Among them, the second spherical surface 3 is concentric with the spherical cap 5, the axis of the spherical cap 5 is inclined relative to the axis of the vertical barrel 1, and the spherical cap 5 performs a circular translational motion around the axis of the vertical barrel 1.

[0036] In detail, the spherical crown 5 is a small portion of the sphere after it has been transversely cut by a plane. The further the plane is from the center of the sphere, the smaller the volume of the spherical crown 5. The vertical barrel 1 is used to hold the raw materials. The radius of the first spherical surface 2 is larger than the radius of the spherical crown 5, and the center of the spherical crown 5 is higher than the center of the spherical crown 5. This allows for sufficient space between the first spherical surface 2 and the spherical crown 5 to facilitate the storage of raw materials and to allow the raw materials to roll downwards along the first spherical surface 2 to the space between the second spherical surface 3 and the spherical crown 5. The space between the first spherical surface 2 and the spherical crown 5 gradually decreases as the vertical height decreases. The gap between the second spherical surface 3 and the spherical crown 5 is smaller to facilitate the grinding of the raw materials. As the raw materials are continuously ground, they gradually move towards the discharge pipe 4 under gravity and are discharged through the discharge pipe 4.

[0037] In practical use, since neither the inner wall of the second spherical surface 3 nor the outer wall of the spherical crown 5 can be perfectly smooth, the second spherical surface 3 can be in direct contact with the spherical crown 5. This allows the raw material to be ground using the tiny gap between the second spherical surface 3 and the spherical crown 5, thereby reducing the size of the ground particles. This tiny gap can also serve as a screening function, preventing larger raw materials from entering the discharge pipe 4 through the gap. Therefore, the working method of the second spherical surface 3 and the spherical crown 5 can achieve both grinding and screening effects. Since the space between the first spherical surface 2 and the spherical crown 5 gradually decreases as the vertical height decreases, it is beneficial for the raw material to gradually enter the space between the second spherical surface 3 and the spherical crown 5, facilitating the continuous grinding and feeding of the raw material.

[0038] Because the axis of the spherical cap 5 is inclined and the spherical cap 5 moves in a circular translation around the axis of the vertical barrel 1, the spherical cap 5 does not rotate. This prevents the spherical cap 5 from being thrown away from the spherical cap 5 by its own rotation, which would make it difficult for the raw material to enter between the second spherical surface 3 and the spherical cap 5. The circular motion of the spherical cap 5 around the axis of the vertical barrel 1 allows the spherical cap 5 to move relative to the second spherical surface 3, thereby allowing the spherical cap 5 to perform rolling and grinding treatment on the raw material between the second spherical surface 3 and the spherical cap 5. This allows for extended crushing by utilizing the weaknesses of the raw material such as cracks and irregular surfaces, making the crushing and grinding of the raw material more convenient.

[0039] By designing a precise gap between the spherical cap 5 and the second spherical surface 3, and a special motion trajectory for the spherical cap 5, uniform and controllable grinding of raw materials can be achieved, effectively solving the problem of uncontrollable raw material crushing effect in traditional grinding methods. The tilting axis and translational motion of the spherical cap 5 ensure that the rotation of the spherical cap 5 does not generate centrifugal force on the raw materials and cause them to detach from the spherical cap 5 during the moving grinding process, thus improving grinding efficiency. The device design eliminates the reliance on traditional screening structures; the tiny gap between the second spherical surface 3 and the spherical cap 5 itself has a screening function, automatically intercepting large particles of raw materials that are not fully ground, reducing additional screening steps, and simplifying the overall structure and operation process. Due to the precise control during the grinding process, the particle size distribution of the final product is more uniform, improving the consistency of product quality. In summary, this inorganic mineral ultrafine grinding device demonstrates significant advantages in improving grinding efficiency, ensuring product quality, simplifying the process, and reducing production costs, and is expected to become a revolutionary solution in the field of inorganic mineral ultrafine grinding.

[0040] like Figure 5 As shown, the spherical surface of the spherical crown 5 is composed of an outer ring tooth region 6 and an inner smooth surface region 7. The ring tooth region 6 and the first spherical surface 2 work together to perform preliminary crushing of the raw materials.

[0041] In detail, the annular tooth region 6 is equipped with densely packed teeth in annular shape. Because the axis of the spherical crown 5 is inclined and it undergoes circular translation around the axis of the vertical barrel 1, when the left side of the spherical crown 5 is higher than its right side, the axis of the spherical crown 5 tilts to the right. As the spherical crown 5 moves, the height of its left side gradually decreases. At this time, part of the annular tooth region 6 on the left side of the spherical crown 5 moves towards the second spherical surface 3. Since the space between the first spherical surface 2 and the spherical crown 5 gradually decreases downwards, the annular tooth region 6 can cooperate with the first spherical surface 2 to crush and compress the raw materials between them. The toothed area 6 prevents the raw material from sliding freely, and the edge of the annular toothed area 6 can effectively squeeze the raw material, thereby improving the initial crushing effect of the raw material. The annular toothed area 6 can also press the raw material between the second spherical surface 3 and the spherical crown 5, thus facilitating the continuous entry of the raw material into the space between the second spherical surface 3 and the spherical crown 5 for grinding. As the spherical crown 5 moves in a circular motion, the annular toothed area 6 on the spherical crown 5 continuously performs initial crushing and pressing of the raw material around the spherical crown 5 into the space between the second spherical surface 3 and the spherical crown 5, thereby improving the grinding efficiency of the raw material. The smooth surface area 7 is used to cooperate with the second spherical surface 3 to crush the raw material.

[0042] like Figure 5 As shown, a top plate 8 is provided on the end face of the spherical crown 5. The outer circumferential wall of the top plate 8 is a spherical surface, and the center of the spherical surface coincides with the center of the top plate 8. A fastening groove plate 9 is fastened on the top plate 8. The outer circumferential wall of the fastening groove plate 9 is set as a spherical surface that mates with the outer circumferential wall of the top plate 8, and the fastening groove plate 9 slides on the top plate 8.

[0043] A guide structure is provided between the spherical crown 5 and the groove plate 9.

[0044] In detail, the top of the grooved plate 9 is sealed, and the spherical surface of the outer circumference of the top plate 8 slides in conjunction with the spherical surface of the outer circumference of the grooved plate 9, meaning the grooved plate 9 can slide freely on the top plate 8. The center of the sphere of the outer circumference of the grooved plate 9 coincides with the center of the top plate 8. When the left side of the spherical crown 5 is higher than the right side, that is, the spherical crown 5 tilts to the right, the bottom of the part of the grooved plate 9 on the right side of the spherical crown 5 contacts the first spherical surface 2. Due to the idleness of the first spherical surface 2, the bottom of the part of the grooved plate 9 on the right side of the spherical crown 5 is close to the top plate 8, while the bottom of the part of the grooved plate 9 on the left side of the spherical crown 5 is away from the top plate 8. At this time, there will be a large gap between the bottom of the part of the grooved plate 9 on the left side of the spherical crown 5 and the spherical crown 5. As the spherical crown 5 rotates, the right side of the spherical crown 5 gradually rises, and the grooved plate on the right side of the spherical crown 5... Plate 9 remains in contact with the first spherical surface 2. That is, the right side of the spherical crown 5 also rises, but the rise distance is small. Meanwhile, the left side of the spherical crown 5 and part of the left side of the spherical crown 5 descend. The descent height of the left side of the spherical crown 5 is small, and there is still a large gap between the left side of the spherical crown 5 and the spherical crown 5. The descent of the left side of the spherical crown 9 will cause it to scoop up the material in the first spherical surface 2 on the left side of the spherical crown 5. That is, the inner wall of the left side of the spherical crown 9 will push the material laterally, so that the material moves towards the space between the second spherical surface 3 and the spherical crown 5, thus realizing the feeding of the material. With the circumferential movement of the spherical crown 5, any position on the spherical crown 9 will continuously move up and down, thereby continuously squeezing the material into the space between the second spherical surface 3 and the spherical crown 5, improving the grinding efficiency.

[0045] The guiding structure can prevent the slotted plate 9 from making circular motion on the top plate 8. That is, according to the circular translational motion of the spherical cap 5, the slotted plate 9 can make the motion synchronously. This avoids the slotted plate 9 being unable to effectively push the raw material when it makes circular motion on the top plate 8. The top plate 8 mainly plays the role of supporting and guiding the slotted plate 9.

[0046] like Figures 6 to 7 As shown, the guide structure includes multiple arc-shaped grooves 10 formed on the spherical crown 5. The arc-shaped grooves 10 penetrate the top plate 8. The center of the arc-shaped grooves 10 coincides with the center of the top plate 8. A sliding plate 11 is slidably disposed in the arc-shaped grooves 10. The sliding plate 11 is fixedly connected to the groove plate 9. A long opening 12 is formed in the middle of the sliding plate 11. The surface of the long opening 12 passes through the center of the top plate 8 and is perpendicular to the top plate 8. A guide post 13 is provided in the arc-shaped grooves 10, passing through the long opening 12, and the long opening 12 slides on the guide post 13.

[0047] The top plate 8 and the groove plate 9 are connected by a spring 14.

[0048] In detail, a fixing groove is opened on the top plate 8, one end of the spring 14 is hidden in the fixing groove, and the other end of the spring 14 is connected to the retaining plate 9. A space is left between the top of the retaining plate 9 and the top of the top plate 8 for the installation of the guide structure and the spring 14. Since the retaining plate 9 can tilt in any direction on the top plate 8, the sliding of the slide plate 11 in the arc groove 10 and the sliding and rotation of the long opening 12 on the guide post 13 can be used to guide and limit the retaining plate 9, so that the retaining plate 9 cannot rotate on the top plate 8, but can only tilt in any direction on the top plate 8. The guide post 13 is located on the center surface of the top plate 8, and the axis of the guide post 13 passes through the center of the top plate 8.

[0049] Spring 14 provides elastic tension to the slotted plate 9. When the slotted plate 9 is tilted on the top plate 8, spring 14 bends or stretches. The natural state of spring 14 is when spring 14 is vertical and the end face of slotted plate 9 is parallel to the top plate 8.

[0050] It can be seen that by using the spring 14, when the axis of the retaining plate 9 tilts to the right, the right side of the retaining plate 9 contacts the right side of the first spherical surface 2, and the left side of the retaining plate 9 separates from the left side of the first spherical surface 2. When the axis of the retaining plate 9 tilts to the left, the left side of the retaining plate 9 contacts the left side of the first spherical surface 2, and the right side of the retaining plate 9 separates from the right side of the first spherical surface 2.

[0051] like Figure 5 As shown, a fixed ball 15 is provided on the top plate 8, the center of the fixed ball 15 coincides with the center of the top plate 8, the fixed ball 15 passes through the fastening groove plate 9, the fastening groove plate 9 is slidably fastened on the fixed ball 15, and a positioning ball 16 is provided on the outer wall of the fixed ball 15 outside the fastening groove plate 9, the center of the positioning ball 16 coincides with the center of the spherical crown 5;

[0052] A power unit is installed inside the vertical barrel 1. The power unit is connected to the positioning ball 16 and is used to provide power for the movement of the spherical crown 5.

[0053] In detail, since the top of the slotted plate 9 is blocked, a fixed ball 15 is needed to provide power to the spherical crown 5 and the top plate 8 by the power unit. In order to avoid the fixed ball 15 interfering with the movement of the slotted plate 9, the center of the fixed ball 15 needs to be aligned with the center of the top plate 8. In this way, the fixed ball 15 and the positioning ball 16 can be used to directly transmit power to the spherical crown 5 and the top plate 8. The positioning ball 16 is mainly set to position the center of the spherical crown 5 to facilitate equipment assembly and the setting of the movement trajectory of the spherical crown 5. The position of the center of the spherical crown 5 remains unchanged when it moves.

[0054] like Figure 8As shown, the power unit includes a power box 17 located on the axis of the vertical barrel 1. The power box 17 is fixedly connected to the inner wall of the vertical barrel 1. A first turntable 18 is rotatably provided at the bottom of the power box 17. The top surface of the first turntable 18 extends into the power box 17. A connecting sleeve 19 is eccentrically fixed on the first turntable 18, and the axis of the connecting sleeve 19 is inclined relative to the axis of the first turntable 18. A rotating column 20 is rotatably provided inside the connecting sleeve 19. Two first connecting columns 21 are inserted and fixed on the rotating column 20. One end of each of the two first connecting columns 21 is fixedly connected to a positioning ball 16. A second connecting column 22 is rotatably provided at the other end of each of the two first connecting columns 21. The second connecting column 22 is vertical. The power box 17 is provided with a positioning structure for limiting the relative position of the two second connecting columns 22.

[0055] In detail, the positioning structure is used to keep the two second connecting posts 22 vertical at all times, and when the first turntable 18 rotates, the two second connecting posts 22 translate in the horizontal direction.

[0056] It can be seen that the axis of the spherical crown 5 coincides with the axis of the connecting sleeve 19, and the axis of the spherical crown 5 is located between the two first connecting columns 21 and parallel to each other. The first connecting column 21 and the second connecting column 22 are rotatably connected by a connecting ball, which allows the first connecting column 21 and the second connecting column 22 to rotate relative to each other in any direction. When the first turntable 18 rotates, the first turntable 18 will drive the connecting sleeve 19, the rotating column 20, the first connecting column 21 and the second connecting column 22 to perform circular motion. The two first connecting columns 21 can drive the top plate 8 and the spherical crown 5 to perform circular motion synchronously through the positioning ball 16 and the fixed ball 15. At this time, the spherical crown 5 moves around the axis of the vertical barrel 1. The two first connecting columns 21 remain in the same position as the two second connecting columns 22, and the two first connecting columns 21 limit the movement trajectory of the rotating column 20. At this time, while the rotating column 20 follows the connecting sleeve 19 to perform a circular motion around the axis of the first turntable 18, the rotating column 20 rotates in the opposite direction relative to the connecting sleeve 19 within the connecting sleeve 19. That is, the rotating column 20 will not rotate relative to the power box 17. Thus, the two first connecting columns 21 cause the spherical crown 5 and the top plate 8 to perform a translational motion. That is, the spherical crown 5 and the top plate 8 will not rotate relative to the vertical barrel 1, thereby realizing the power supply to the spherical crown 5 and the top plate 8.

[0057] like Figure 8 As shown, the power box 17 has a partition in the middle, and a second turntable 23 is rotatably mounted on the partition. An actuating disk 24 is eccentrically mounted on the second turntable 23. Both second connecting columns 22 slide through the actuating disk 24. The power box 17 is equipped with a motor 25 for providing power to the second turntable 23.

[0058] In detail, the motor 25 is fixed to the top of the inner wall of the power box 17. The output end of the motor 25 is connected to the second turntable 23 on the inner partition of the power box 17. The second turntable 23 passes through the partition, and the actuating disk 24 passes through the second turntable 23. The tops of the two second connecting posts 22 slide through the actuating disk 24. When the motor 25 drives the second turntable 23 to rotate, the second turntable 23 can drive the two second connecting posts 22 to perform circular motion through the actuating disk 24. Due to the limitation of the positioning structure, the two second connecting posts 22 will drive the actuating disk 24 to rotate relative to the second turntable 23, and the actuating disk 24 will perform translational motion.

[0059] It should be noted that, due to the tilt of the axis of the spherical cap 5, the relative height position between the two second connecting posts 22 changes as the spherical cap 5 rotates, that is, the second connecting posts 22 will be displaced in the vertical direction. At this time, it is necessary to enable the second connecting posts 22 to slide on the dial 24.

[0060] like Figure 8 As shown, the positioning structure includes a connecting seat 26 mounted on two second connecting posts 22. The second connecting posts 22 pass through the connecting seat 26 and slide relative to each other. A slide rod 27 is horizontally slidably inserted on the connecting seat 26. The end of the slide rod 27 is horizontally slidably mounted on the inner wall of the power box 17, and the moving direction of the slide rod 27 and the moving direction of the connecting seat 26 on the slide rod 27 are perpendicular to each other.

[0061] In detail, since the second connecting post 22 will be displaced in the vertical direction, the second connecting post 22 needs to be slidably connected to the connecting seat 26. The setting of the slide rod 27 and the connecting seat 26 can limit the orientation of the two second connecting posts 22, so that the two second connecting posts 22 cannot rotate and can only perform translational movement.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
