Description

Technical Field

[0001] This invention relates to the field of ceramic powder preparation technology, specifically to an apparatus and method for preparing uniform and fine ceramic powder. Background Technology

[0002] Ceramic micron powder is a lightweight, non-metallic, multifunctional material, mainly composed of SiO2 and Al2O3. It exhibits good dispersibility, high hiding power, high whiteness, good suspension properties, good chemical stability, good plasticity, high heat resistance, low density, low loss on ignition, good light scattering, and good insulation. It can improve various properties of coatings, enhance the mechanical properties of paint films, increase transparency, and improve fire resistance. It can be used in anti-corrosion, fireproofing, high-temperature resistant, powder coatings, architectural coatings, and various industrial applications. However, ceramic powder requires high fineness during processing, necessitating the use of equipment capable of preparing uniform and fine ceramic powder.

[0003] Existing equipment for preparing uniform and fine ceramic powder typically employs a grinding method. The ceramic powder raw material is fed into the grinding equipment, and the ceramic powder is squeezed and rubbed by grinding rollers or grinding discs, making the ceramic powder finer and more pulverized during the continuous grinding process.

[0004] However, in actual use, the above-mentioned equipment results in poor mixing and dispersion of ceramic powder during grinding, especially in single-pass grinding equipment without a sieving device. This easily leads to different uniformity of ceramic powder in different areas, greatly reducing the fineness of the grinding. In view of this, we propose an equipment and method for preparing uniform and fine ceramic powder. Summary of the Invention

The end of the rotating rod is rotatably mounted on the inner wall of the mounting base. The end of a spiral spring is fixedly connected to the inner wall of the mounting base. The other end of the spiral spring is fixedly connected to the arc-shaped outer wall of the rotating rod. The end of a connecting rod is fixedly connected to the end of the rotating cylinder. The other end of the connecting rod is rotatably mounted on the inner wall of the auxiliary disk. A worm gear passes through the connecting rod and is fixedly connected to the worm gear. The end of a worm is rotatably mounted on the inner wall of the auxiliary disk. A transmission wheel passes through the worm and is fixedly connected to the transmission wheel.

[0013] Preferably, the inner wall of the auxiliary disk has a storage cavity, and the side of the storage cavity has a rectangular groove with a height adapted to the thickness of the transmission wheel, so that the arc-shaped outer surface of the transmission wheel can extend to the outside of the rectangular groove.

[0014] Preferably, the interior of the receiving groove is provided with a turbulence-disrupting component, the turbulence-disrupting component includes a lever, the lever is fixedly installed on the inner surface of the receiving groove, a top rod is slidably installed on the inner wall of the flip plate, one end of the hinge strip is hinged to the inner wall of the top rod, the other end of the hinge strip is hinged to a magnetic block, a turbulence-disrupting plate is rotatably installed on the side wall of the flip plate, and an installation hole is opened on the inner wall of the end of the turbulence-disrupting plate.

[0023] Compared with the prior art, the present invention provides an apparatus and method for preparing uniform and fine ceramic powder, which has the following beneficial effects:

[0024] 1. The apparatus and method for preparing uniform and fine ceramic powder, in order to avoid poor mixing efficiency between ceramic powders at different locations and reduce the overall fineness and uniformity of the ceramic powder, is equipped with an auxiliary dispersion component. With the rotation of the auxiliary disk, the rotating cylinder in the receiving tank will be deflected by the resistance of the flipping plate. At this time, by setting multiple sets of flipping plates, the flipping plates will stir and mix the ceramic powder during the grinding process with the auxiliary disk, improve the mixing effect between ceramic powders at different locations, further improve the uniformity and fineness of the ceramic powder mixing, and improve the processing effect of the ceramic powder.

[0025] 2. The equipment and method for preparing uniform and fine ceramic powder, in order to better ensure that the turning plate turns the ceramic powder in the inner wall of the bottom of the grinding cylinder, is equipped with a transmission component. In conjunction with the contact transmission between the transmission wheel and the inner surface of the annular groove of the grinding disc, the connecting rod can actively drive the rotating cylinder to rotate. This prevents the rotating cylinder from jamming due to the large particle size of the ceramic powder in the early stage of processing, and ensures the mixing efficiency of the ceramic powder.

[0026] 3. The equipment and method for preparing uniform and fine ceramic powder, in order to improve the turbulence effect of the flipping plate on the ceramic powder, is equipped with a turbulence component. In conjunction with the lever, the top rod is periodically pushed and squeezed. The magnetic plate set on the magnetic block and the side wall of the turbulence plate makes the turbulence plate swing periodically around the shaft in the mounting hole as the rotation center, thereby turbulently blowing the ceramic powder on the side of the flipping plate, improving the mixing effect of the ceramic powder in the horizontal direction, and thus improving the fineness of the device for grinding and processing ceramic powder.

[0036] like Figure 1-8As shown, the present invention provides a technical solution: an apparatus and method for preparing uniform and fine ceramic powder, comprising a grinding cylinder 1, a cover 2 snapped onto the top of the grinding cylinder 1, a handle 3 fixedly installed on the top outer wall of the cover 2, a discharge valve 4 fixedly installed on the bottom outer wall of the grinding cylinder 1, a drive motor 5 fixedly installed on the bottom outer wall of the grinding cylinder 1, the bottom end of a rotating shaft 6 fixedly installed at the output end of the drive motor 5, a grinding disc 10 fixedly installed on the arc-shaped outer wall of the rotating shaft 6, an auxiliary dispersion assembly provided inside the grinding cylinder 1, the auxiliary dispersion assembly including a drive gear 7, the drive gear 7 passing through the rotating shaft 6 and fixedly connected to the rotating shaft 6, an auxiliary disc 8 rotatably installed on the inner surface of the grinding disc 10, a driven gear 9 rotatably installed on the side wall of the auxiliary disc 8, a receiving groove 11 opened on the lower surface of the auxiliary disc 8, the end of a rotating cylinder 12 rotatably installed on the inner surface of the receiving groove 11, a mounting base 13 fixedly installed on the arc-shaped outer wall of the rotating cylinder 12, and a flipping plate 14 rotatably installed on the side wall of the mounting base 13.

[0037] In one embodiment of the present invention, the top of the grinding cylinder 1 is open, and the opening is adapted to the cover 2, so that the cover 2 can seal the top of the grinding cylinder 1 after the raw material is put into the device, so as to prevent the ceramic powder from escaping and affecting the material discharge. In addition, the discharge valve 4 is a solenoid valve to facilitate the operation of the operator to discharge the material. At the same time, the drive motor 5 and the discharge valve 4 are electrically connected to the external 220V mains power to supply power to the drive motor 5 and the discharge valve 4, ensuring the normal operation of the device. Furthermore, the rotating shaft 6 passes through the grinding disc 10, and the interior of the grinding disc 10 is hollow to facilitate the installation of the auxiliary disc 8. In addition, the bottom of the auxiliary disc 8 is provided with a protrusion, and the protrusion is annular. Specifically, the bottom outer wall of the grinding disc 10 is provided with an annular groove adapted to the protrusion, so that the auxiliary disc 8 can be inserted into the grinding disc. During installation, the protrusion extends precisely to the outside of the annular groove, and the lower surface of the protrusion is flush with the lower surface of the grinding disc 10. This allows the grinding disc 10 and the auxiliary disc 8 to work together to grind the ceramic powder inside the grinding cylinder 1. In addition, a cylindrical cavity is provided at the axis of the auxiliary disc 8 to facilitate the installation of the driving gear 7 and the driven gear 9. Specifically, the driven gear 9 meshes with the driving gear 7 to achieve transmission. At the same time, the inner surface of the cylindrical cavity is provided with teeth that can mesh with the driven gear 9. This allows the auxiliary disc 8 to maintain a lower rotational speed relative to the rotating shaft 6 when the shaft 6 rotates, in conjunction with the driving gear 7 and the driven gear 9. Specifically, a certain speed difference is maintained between the auxiliary disc 8 and the grinding disc 10, so that the movement speed of the ceramic powder corresponding to the auxiliary disc 8 and the grinding disc 10 is different, allowing for better mixing.

[0038] In an embodiment of the present invention, multiple sets of receiving grooves 11 are provided, and these multiple sets of receiving grooves 11 are evenly arranged in a circumferential array on the lower surface of the protrusion of the auxiliary disk 8. Simultaneously, the two ends of the rotating cylinder 12 are respectively rotatably disposed on the inner surfaces of the left and right sides of the receiving grooves 11. Furthermore, four sets of mounting seats 13 are provided, and these four sets of mounting seats 13 are evenly distributed in a circumferential array on the arc-shaped outer wall of the rotating cylinder 12. Further, the flipping plate 14 is arranged parallel to the rotating cylinder 12, so that when the rotating cylinder 12 rotates, the flipping plate 14 rotates synchronously with the rotating cylinder 12. Similarly, the flipping plate 14... When it is touched and moved, it will start to rotate along with the rotating drum 12. In addition, mounting seats 13 are provided on both the left and right sides of the flip plate 14 to ensure that the flip plate 14 can maintain a relatively balanced force during installation. Furthermore, the flip plate 14, which is rotatably mounted on the side wall of the mounting seat 13, will not interfere with the rotation of the rotating drum 12. Moreover, when the flip plate 14 rotates to the lowest point, the lower surface of the flip plate 14 will squeeze the bottom inner wall of the grinding drum 1, so that the flip plate 14 will deflect due to the influence of ceramic powder during the rotation of the rotating drum 12.

[0039] In addition, to better ensure that the flipping plate 14 flips the ceramic powder in the inner wall of the bottom of the grinding cylinder 1, the auxiliary disk 8 is provided with a transmission assembly. The transmission assembly includes a rotating rod 15. The end of the rotating rod 15 is rotatably mounted on the inner wall of the mounting base 13. The end of the spiral spring 16 is fixedly connected to the inner wall of the mounting base 13. The other end of the spiral spring 16 is fixedly connected to the arc-shaped outer wall of the rotating rod 15. The end of the rotating cylinder 12 is fixedly connected to the end of the connecting rod 17. The other end of the connecting rod 17 is rotatably mounted on the inner wall of the auxiliary disk 8. The connecting rod 17 passes through the worm gear 18 and is fixedly connected to the connecting rod 17. The end of the worm 19 is rotatably mounted on the inner wall of the auxiliary disk 8. The worm 19 passes through the transmission wheel 20 and is fixedly connected to the worm 19.

[0040] In an embodiment of the present invention, the end of the rotating rod 15 away from the inner wall of the mounting base 13 is fixedly connected to the side wall of the flip plate 14, and the spiral spring 16 is sleeved on the arc-shaped outer wall of the rotating rod 15. Specifically, when the flip plate 14 is in a vertical state, the spiral spring 16 is in an unstretched and uncompressed state. In other words, no matter what angle the flip plate 14 is deflected to, under the elastic force of the spiral spring 16, the flip plate 14 can maintain the tendency to return to its original position. Furthermore, the inner wall of the auxiliary disk 8 is provided with a storage cavity so that the connecting rod 17, the worm gear 18, the worm 19, and the transmission wheel 20 can be installed inside the storage cavity. At the same time, the worm gear... The worm gear 18 meshes with the worm 19 to achieve transmission. Due to the reverse self-locking between the worm gear 18 and the worm 19, the worm gear 18 can only be driven to rotate by the worm 19, which in turn drives the connecting rod 17 to rotate. In addition, a rectangular groove with a height that matches the thickness of the transmission wheel 20 is provided on the side of the receiving cavity, so that the arc-shaped outer surface of the transmission wheel 20 can extend out of the rectangular groove. Specifically, a rubber pad is provided on the arc-shaped outer surface of the transmission wheel 20 to improve the contact effect between the transmission wheel 20 and the inner surface of the annular groove of the grinding disc 10, avoid slippage, and ensure the transmission effect between the worm gear 19 and the worm wheel 18.

[0041] In addition, in order to improve the turbulence effect of the flip plate 14 on the ceramic powder, a turbulence component is provided inside the receiving tank 11. The turbulence component includes a lever 21. The lever 21 is fixedly installed on the inner surface of the receiving tank 11. A top rod 22 is slidably installed on the inner wall of the flip plate 14. One end of the hinge strip 23 is hinged to the inner wall of the top rod 22. A magnetic block 24 is hinged to the other end of the hinge strip 23. A turbulence plate 25 is rotatably installed on the side wall of the flip plate 14. An installation hole 26 is opened on the inner wall of the end of the turbulence plate 25.

[0042] In an embodiment of the present invention, the lever 21 is disposed on the side of the receiving groove 11 near the center of the auxiliary disk 8, and the left end of the push rod 22 is adapted to the position of the lever 21. This allows the push rod 22 inside the flip plate 14 to periodically contact the lever 21 as the rotating drum 12 rotates continuously. Simultaneously, both the end of the push rod 22 and the end of the lever 21 are provided with rounded heads, allowing the lever 21 to abut against the push rod 22 that has moved to the lever 21, causing the push rod 22 to move horizontally. Specifically, the push rod 22 is configured as an elastic telescopic rod, so that when the push rod 22 moves to the point of disengagement from the lever 21, due to the inherent characteristics of the elastic telescopic rod, the push rod 22 will perform a reset movement, facilitating continued contact between the push rod 22 and the lever 21 during subsequent movements. Furthermore, the magnetic block 24 is square, and the inner... The wall has a square hole that matches the size of the magnetic block 24, so that the magnetic block 24 will slide along the inner wall of the square groove after being pushed by the hinge bar 23. In addition, the mounting hole 26 at the end of the spoiler 25 is provided with a shaft for the spoiler 25 to rotate, and a coil spring is sleeved on the outside of the shaft, so that the spoiler 25 has a reset function after deflection. A magnetic plate with the same magnetism as the magnetic block 24 is provided on the outer wall of the spoiler 25 near the center of the flip plate 14, so that when the magnetic block 24 approaches the spoiler 25, the spoiler 25 will rotate around the shaft provided in the mounting hole 26 as the rotation center. When the top rod 22 is reset, the magnetic block 24 moves away from the spoiler 25. Affected by the coil spring in the mounting hole 26, the spoiler 25 will deflect towards the flip plate 14 to reset. During this process, the ceramic powder on the side of the flip plate 14 is turbulently blown.

[0043] In this invention, during use, the ceramic powder raw material is placed at the bottom of the grinding cylinder 1. The rotating shaft 6 and grinding structure are then installed. The drive motor 5 is started, and with the rotation of the rotating shaft 6, the grinding disc 10 and the auxiliary disc 8 maintain different rotational speeds under the cooperation of the drive gear 7 and the driven gear 9. This ensures that the ceramic powder raw material at the bottom of the grinding cylinder 1 achieves a sufficient grinding effect. To avoid poor mixing efficiency between ceramic powders at different locations and reduce the overall fineness and uniformity of the ceramic powder, an auxiliary dispersion component is provided. With the rotation of the auxiliary disc 8, the rotating cylinder 12 in the receiving tank 11 is deflected by the resistance of the tilting plate 14. The multiple tilting plates 14, during the grinding process with the auxiliary disc 8, agitate and mix the ceramic powder, improving the mixing effect between ceramic powders at different locations and further enhancing the uniformity and fineness of the ceramic powder mixture. In addition to improving the processing effect of ceramic powder, to better ensure that the rotating plate 14 flips the ceramic powder in the inner wall of the bottom of the grinding cylinder 1, a transmission component is provided. In conjunction with the contact transmission between the transmission wheel 20 and the inner surface of the annular groove of the grinding disc 10, the connecting rod 17 can actively drive the rotating cylinder 12 to rotate. This prevents the rotating cylinder 12 from jamming due to the large size of the ceramic powder particles in the early stage of processing, ensuring the mixing efficiency of the ceramic powder. At the same time, in order to improve the turbulence effect of the rotating plate 14 on the ceramic powder, a turbulence component is provided. In conjunction with the lever 21, the top rod 22 is periodically pushed and squeezed. The magnetic plates provided on the side walls of the magnetic block 24 and the turbulence plate 25 cause the turbulence plate 25 to periodically swing around the axis in the mounting hole 26 as the rotation center, thereby turbulently blowing the ceramic powder on the side of the rotating plate 14, improving the mixing effect of the ceramic powder in the horizontal direction, and thus improving the fineness of the device in grinding ceramic powder.

[0044] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
