Description

Technical Field

[0001] This utility model relates to the field of ceramic material preparation technology, and in particular to a ceramic powder fine grinding device. Background Technology

[0002] Ceramic powder is a key raw material in the ceramic production process. It is a powdery substance used to manufacture ceramic products, and its physical properties are very important to ceramic production. Its particle size distribution directly affects the quality and performance of the ceramic body. Finer powder particles can make the body more compact, improving the strength and surface smoothness of the ceramic. With the continuous development of the ceramic industry, the requirements for the particle size and quality of ceramic powder are becoming increasingly stringent.

[0003] Existing ball milling devices simply use the rotation of the tank to drive the raw materials and grinding balls to grind the raw materials. During the grinding process, ceramic powder may agglomerate, resulting in insufficient contact between the grinding balls and the raw materials, which leads to low efficiency. Furthermore, the internal structure of the tank in existing ball milling devices is relatively simple, and the angle and number of collisions and grinding of ceramic powder are not sufficient, resulting in insufficient grinding.

[0022] Example 1

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: a ceramic powder fine grinding device, including a base 1, a support column 2 arranged in a ring array fixedly connected to the inner bottom wall of the base 1, an mounting plate 3 fixedly connected to the upper end of each of the support column 2, a rotating groove 4 opened at the upper end of the mounting plate 3, an annular rotating block 5 rotatably sleeved on the inner wall of the rotating groove 4, a rotating disk 6 fixedly connected to the upper end of the annular rotating block 5, an inclined block 7 arranged in a ring array fixedly connected to the upper end of the rotating disk 6, and a first servo motor 8 fixedly installed on the lower surface of the mounting plate 3;

[0024] The output shaft of the first servo motor 8 is fixedly connected to the first rotating shaft 9 via a coupling. One end of the first rotating shaft 9 passes through and extends to the upper end of the mounting plate 3. The other end of the first rotating shaft 9 is fixedly connected to the lower surface of the rotating plate 6. With the cooperation of the rotating slide 4 and the annular rotating block 5, the first servo motor 8 drives the rotating plate 6 to rotate via the first rotating shaft 9, thereby driving the inclined block 7 to rotate. The rotation of the inclined block 7 drives the mounting platform 15 to vibrate via the rotating wheel 12 and the cylindrical rod 11.

[0025] Example 2

[0026] like Figure 1-4As shown, this utility model provides a technical solution: the upper end of the base 1 is provided with a first mounting hole 10 arranged in a ring array, the inner wall of the first mounting hole 10 is slidably sleeved with a cylindrical rod 11, and one end of the cylindrical rod 11 is provided with a rotating wheel 12.

[0027] The outer surfaces of multiple rotating wheels 12 are in contact with the upper end of the rotating disk 6. The upper end of the base 1 is provided with a second mounting hole 13 arranged in a rectangular array. The inner wall of the second mounting hole 13 is slidably fitted with a guide rod 14. The upper ends of multiple guide rods 14 are fixedly connected to a mounting platform 15. The upper ends of multiple cylindrical rods 11 are fixedly connected to the lower surface of the mounting platform 15.

[0028] The upper end of the base 1 is fixedly connected with a rectangular array of support springs 16, one end of each of the support springs 16 being fixedly connected to the lower surface of the mounting platform 15.

[0029] The upper end of the mounting platform 15 is fixedly connected to symmetrically distributed mounting seats 17. The inner wall of the mounting seat 17 is fitted with a third rotating shaft 18 via bearings. The opposite ends of the two third rotating shafts 18 are fixedly connected to rotating cylinders 19.

[0030] The outer surface of the rotating drum 19 is provided with a material hole 20, and the inner wall of the material hole 20 is provided with a sealing plate 21. The inner wall of the rotating drum 19 is fixedly connected with impact blocks 22 distributed in a ring array. The setting of the impact blocks realizes the continuous process of impact crushing and fine grinding of ceramic powder, which greatly improves the grinding efficiency and effect. Grinding balls 23 are set inside the rotating drum 19.

[0031] A gear ring 24 is fixedly sleeved on the outer surface of the rotating drum 19. A second servo motor 25 is fixedly installed on the upper end of the mounting platform 15 through a heightening block. The output shaft of the second servo motor 25 is fixedly connected to a second rotating shaft 26 through a coupling. A gear 27 is fixedly sleeved on the outer surface of one end of the second rotating shaft 26. The tooth surface of the gear 27 meshes with the tooth surface of the gear ring 24.

[0032] By setting up the inclined blocks and rotating wheels, the ceramic powder can be dispersed as much as possible inside the rotating drum, preventing the ceramic powder from agglomerating. During the rotation of the drum, the contact between the grinding balls and the ceramic powder inside is more thorough, and the ceramic powder can be ground more evenly. The setting of the impact blocks allows the ceramic powder to undergo a continuous process of impact crushing followed by fine grinding, improving grinding efficiency and the degree of grinding fineness.

[0033] The working process of this utility model:

[0034] Step 1: The ceramic powder raw material is fed into the rotating drum 19 through the feed inlet. The feed inlet is then closed using the sealing plate 21. The second servo motor 25 is started, which drives the gear 27 to rotate through the second rotating shaft 26. With the cooperation of the two third rotating shafts 18, the rotating drum 19 is driven to rotate through the meshing gear ring 24. This causes the raw material and grinding balls 23 inside to rotate and rub against each other. Furthermore, the setting of the impact block 22 allows the raw material to have more opportunities for impact and friction, thereby improving the grinding efficiency.

[0035] Step two: Simultaneously, the first servo motor 8 is started. With the cooperation of the rotating slide 4 and the annular rotating block 5, the first rotating shaft 9 drives the rotating disk 6 to rotate, thereby driving the inclined block 7 to rotate. The rotation of the inclined block 7 drives the mounting platform 15 to vibrate through the rotating wheel 12 and the cylindrical rod 11, thereby increasing the grinding opportunity between the grinding ball 23 and the impact block 22 and the raw material inside the rotating cylinder 19. The contact between the grinding ball 23 and the raw material is more sufficient and uniform, effectively solving the problem of powder agglomeration and improving the grinding efficiency.
