Description

Technical Field

[0001] This utility model relates to the field of porcelain insulator blank processing technology, and in particular to a porcelain insulator blank processing equipment. Background Technology

[0002] Porcelain insulator blanks refer to semi-finished ceramic materials used to manufacture porcelain insulators, which are in an intermediate state after forming but before sintering.

[0003] When processing electrical porcelain insulator blanks, crushing and grinding are required to further refine the particles, improve uniformity, enhance the sintering activity of the powder, and optimize the density and mechanical properties of the final porcelain body. However, ball mills are often used for crushing. Traditional ball mills rely on the mixing of grinding balls to crush the material, but this can easily lead to over-crushing (fine particles are repeatedly ground) or the retention of coarse particles (large particles are not fully broken), resulting in uneven particle size distribution. Electrical porcelain blanks (such as kaolin and alumina mixtures) are sensitive to particle size distribution and particle shape, and uneven particle size distribution can have adverse effects on subsequent production. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, when traditional ball mills are used for grinding, they rely on the mixing of grinding balls to crush materials, but this can easily lead to over-grinding of materials (fine particles are repeatedly ground) or the retention of coarse particles (large particles are not fully crushed), which can easily lead to uneven particle size distribution. Electric porcelain blanks (such as kaolin and alumina mixtures) are sensitive to particle size distribution and particle shape, and uneven particle size distribution can have an adverse effect on subsequent production.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a porcelain insulator blank processing equipment, comprising:

[0006] Mounting frame, on which a grinding roller is rotatably connected;

[0007] The grinding roller is provided with a fine grinding chamber and a coarse grinding chamber. A partition plate is fixedly connected between the fine grinding chamber and the coarse grinding chamber. A partition filter screen is provided in the partition plate.

[0008] The spiral stirring rods are respectively arranged in two chambers;

[0009] The drive mechanism is connected to the grinding drum drive; through the design of dual-chamber division of labor + spiral stirring, it achieves the effect of physical isolation and graded grinding and forced material flow, which can improve the particle uniformity of the material after grinding, make it more suitable for electric porcelain insulator blanks, and improve processing efficiency.

[0010] In a preferred embodiment, the spiral stirring rod assembly includes multiple spiral stirring rods, with both ends of the spiral stirring rods fixedly connected between the partition plate and the inner wall of the grinding drum, respectively, to force the material to circulate and prevent accumulation.

[0011] In a preferred embodiment, the drive mechanism includes a connecting frame fixedly mounted on the horizontal end of the mounting bracket, a rotating shaft rotatably connected between the connecting frame and the vertical end of the mounting bracket, a drive gear fixedly sleeved on the outer circumference of the rotating shaft, a drive gear ring fixedly sleeved on the grinding roller corresponding to the drive gear, the drive gear meshing with the drive gear ring for transmission, and an output shaft fixedly connected to the end of the mounting bracket and a drive motor fixedly connected to the rotating shaft.

[0012] In a preferred embodiment, the coarse grinding chamber is provided with a plurality of coarse grinding balls, and the fine grinding chamber is provided with a plurality of fine grinding balls. The diameter of the coarse grinding balls is 8-15mm, and the diameter of the fine grinding balls is 3-8mm. By setting grinding balls of different diameters, it is possible to adapt to materials of different diameters for more suitable crushing and grinding.

[0013] In a preferred embodiment, the outer sides of the coarse grinding chamber and the fine grinding chamber are fixedly connected with grinding liner plates that are assembled from each other. The grinding liner plates are made of polyurethane material, which has good elasticity, can buffer the impact of steel balls, reduce energy consumption and noise, and has less contamination to materials.

[0014] In a preferred embodiment, a filter screen is fixedly embedded in the discharge port, so that only materials that meet the pulverization size requirement can be discharged, thus ensuring the quality of the output materials.

[0015] In a preferred embodiment, two maintenance plates are fixedly connected to the outer periphery of the grinding roller by bolts, which facilitates the replacement and maintenance of worn grinding inner liner, fine grinding ball and coarse grinding ball.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a processing equipment for electrical porcelain insulator blanks, comprising:

[0026] Mounting frame 1, with a grinding roller 3 rotatably connected to the mounting frame 1. The grinding roller 3 has an inlet 5 and an outlet 6 on both sides respectively.

[0027] The grinding roller 3 is provided with a fine grinding chamber 13 and a coarse grinding chamber 12. A partition plate 16 is fixedly connected between the fine grinding chamber 13 and the coarse grinding chamber 12. A separation filter screen is provided in the partition plate 16.

[0028] The drive mechanism is connected to the grinding roller 3 via a transmission.

[0029] The spiral stirring rod assembly is set in two chambers. Through the dual-chamber division of labor and spiral stirring design, it achieves the effects of physical isolation, graded grinding and forced material flow, which can improve the particle uniformity of the material after grinding, making it more suitable for electrical porcelain insulator blanks and improving processing efficiency.

[0030] like Figure 1-4As shown, the spiral stirring rod assembly includes multiple spiral stirring rods 9. The two ends of the spiral stirring rods 9 are fixedly connected between the partition plate 16 and the inner wall of the grinding roller 3, respectively, to force the material to circulate and prevent accumulation.

[0031] like Figure 1-4 As shown, the drive mechanism includes a connecting frame 17 fixedly installed on the horizontal end of the mounting frame 1. A rotating shaft 18 is rotatably connected between the connecting frame 17 and the vertical end of the mounting frame 1. A drive gear 14 is fixedly sleeved on the outer periphery of the rotating shaft 18. A drive gear ring 7 is fixedly sleeved on the grinding roller 3 corresponding to the drive gear 14. The drive gear 14 and the drive gear ring 7 are meshed and connected for transmission. An output shaft is fixedly connected to the end of the mounting frame 1, and a drive motor 2 is fixedly connected to the rotating shaft 18. The drive motor 2 is used as a power output source. The drive gear 14, in conjunction with the drive gear ring 7, can drive the grinding roller 3 to rotate.

[0032] like Figure 1-4 As shown, the coarse grinding chamber 12 is provided with multiple coarse grinding balls 10, and the fine grinding chamber 13 is provided with multiple fine grinding balls 11. The diameter of the coarse grinding balls 10 is 8-15mm, and the diameter of the fine grinding balls 11 is 3-8mm. The grinding balls of different diameters are provided to adapt to materials of different diameters for more suitable crushing and grinding.

[0033] like Figure 1-4 As shown, the coarse grinding chamber 12 and the fine grinding chamber 13 are fixedly connected to the outside of the grinding liner plate 15, which is assembled from each other. The grinding liner plate 15 is made of polyester-amino material.

The drive motor 2 is used as the power output source, and the drive gear 14 and the drive gear ring 7 drive the grinding drum 3 to rotate. The spiral stirring rod 9 can promote the material circulation to prevent accumulation. With the help of the coarse grinding balls 10, the material is crushed under the action of gravity.
