[0039] The present invention provides a manufacturing method of a high-strength disc-shaped porcelain insulator as Figures 1 to 12 shown, including the following operation steps:

[0040] S1. Laminating, placing the porcelain clay block in the crushing device, and crushing and sieving it step by step from top to bottom;

[0041] S2. Turning, tilting and inverting the crushing device to drive the porcelain clay block to turn and prevent the porcelain clay block from flowing back; Since it is crushing and sieving step by step, when the crushing device drives the porcelain clay block to turn, by preventing the porcelain clay block from flowing back, the situation of reverse sieving is avoided;

[0042] S3. Discharging, crushing the porcelain clay block into powder.

[0043] The present invention adopts the method of crushing the porcelain clay block step by step, and when the crushing device drives the porcelain clay block to turn, by preventing the porcelain clay block from flowing back, the situation of reverse sieving is avoided, and the manufacturing efficiency of the high-strength disc-shaped porcelain insulator is improved.

[0044] Specifically, the crushing device includes an outer box 1, a frame 2 is arranged outside the outer box 1, rotating shafts 22 are fixedly connected to both outer side walls of the outer box 1, one end of each rotating shaft 22 far from the outer box 1 is rotatably connected to the frame 2, a first motor 23 is fixedly connected to the frame 2, and one of the rotating shafts 22 is fixedly connected to the driving shaft of the first motor 23. The first motor 23 drives the rotating shaft 22 fixedly connected to its driving shaft to rotate, and with the cooperation of the other rotating shaft 22, the outer box 1 rotates.

[0045] In actual use, a discharging and suction device can be connected to the outer box 1. The suction device includes structures such as a material pump, which is used to timely suck away the powder after the porcelain clay blocks are broken.

[0046] At the top of the outer box 1, there is an inner cylinder 4 for placing porcelain clay blocks. A through groove 3 is opened at the top of the outer box 1, and the inner cylinder 4 is rotatably arranged inside the through groove 3. A driving assembly for driving the inner cylinder 4 to rotate is arranged outside the outer box 1. The driving assembly includes a second motor 24, a first gear 25, and a second gear 26. The second motor 24 is fixedly connected to the outer wall of the outer box 1. The first gear 25 is fixedly connected to the driving shaft of the second motor 24. The second gear 26 is fixedly connected to the inner cylinder 4. The first gear 25 and the second gear 26 are meshed and connected. The second motor 24 drives the first gear 25 to rotate. Since the first gear 25 and the second gear 26 are meshed and connected, the second gear 26 drives the inner cylinder 4 to rotate.

[0047] Considering that in the prior art, porcelain clay blocks are usually put into a stirring mill to break and grind the whole porcelain clay blocks, and the grinding time is long. To improve the manufacturing efficiency, a dividing plate 7 is fixedly connected inside the inner cylinder 4. There are multiple dividing plates 7, and the dividing plates 7 divide the interior of the inner cylinder 4 into multiple grinding chambers 8, which is convenient for step-by-step crushing. The top of the inner cylinder 4 is fitted with a cover plate 21.

[0048] A plurality of grinding media 9 are arranged inside the grinding chamber 8. The porcelain clay blocks are squeezed, collided with, and rubbed against the grinding media 9 to achieve the effect of crushing.

[0049] A number of third round holes 10 are opened on the dividing plate 7. The sizes of the third round holes 10 on each dividing plate 7 decrease sequentially from top to bottom.

[0050] A number of first round holes 5 are opened on the side wall of the inner cylinder 4, and a number of second round holes 6 are opened at the bottom of the inner cylinder 4. The inner diameter of the second round holes 6 is the same as that of the first round holes 5. The inner diameters of the first round holes 5 and the second round holes 6 are smaller than the inner diameter of the smallest third round hole 10.

[0051] In actual use, start the first motor 23. The first motor 23 drives the rotating shaft 22 fixedly connected to its driving shaft to rotate. With the cooperation of another rotating shaft 22, mechanisms such as the outer box 1 and the inner cylinder 4 rotate, adjust the inner cylinder 4 to a vertical state, and the cover plate 21 is located at the top of the inner cylinder 4 (refer to Figure 5 ).

[0052] The operator removes the cover plate 21, pours the large porcelain clay blocks into the grinding chamber 8 at the uppermost position, and then covers the cover plate 21.

[0053] Start the second motor 24. The second motor 24 drives the first gear 25 to rotate. Since the first gear 25 and the second gear 26 are meshed and connected, the second gear 26 drives the inner cylinder 4 to rotate, and the grinding medium 9 makes a rotary motion. The large kaolin blocks are squeezed, collided with, and rubbed against the grinding medium 9. The large kaolin blocks are broken and become medium kaolin blocks. Part of the powder is discharged into the outer box 1 through the corresponding first round holes 5; the medium kaolin blocks pass through the corresponding third round holes 10 and fall into the grinding chamber 8 at the lower position. The medium kaolin blocks are squeezed, collided with, and rubbed against the grinding medium 9. The medium kaolin blocks are broken and become small kaolin blocks. Part of the powder is discharged into the outer box 1 through the corresponding first round holes 5; the small kaolin blocks pass through the corresponding third round holes 10 and fall into the grinding chamber 8 at the lower position. The small kaolin blocks are squeezed, collided with, and rubbed against the grinding medium 9. The small kaolin blocks are completely broken and become powder. The powder is discharged into the outer box 1 through the second round holes 6 and the corresponding first round holes 5.

[0054] A plurality of grinding chambers 8 are provided to perform high-efficient crushing layer by layer and stage by stage, improve the manufacturing efficiency, ensure the quality and uniformity of the powder, and improve the strength for subsequent manufacturing and use of the disc-shaped porcelain insulators.

[0055] Considering that only by the rotation of the inner cylinder 4 for crushing, the kaolin blocks are likely to accumulate at the lower half position of the grinding chamber 8 due to the action of gravity. To realize the turning of the kaolin blocks, the outer box 1 can be driven to tilt and invert the inner cylinder 4. However, in the present invention, the method of crushing layer by layer and stage by stage is adopted. When the inner cylinder 4 is tilted and inverted, the kaolin blocks are likely to flow back, that is, pass through the third round holes 10 on the same dividing plate 7 in the reverse direction, affecting the efficiency of crushing layer by layer and stage by stage. To complete the partition between two adjacent grinding chambers 8, blocking components are provided on both sides below the dividing plate 7. The blocking components include arc grooves 11 and semi-circular discs 12. The arc grooves 11 are opened on the side wall of the inner cylinder 4. The thickness of the arc grooves 11 is small. The semi-circular discs 12 are slidably arranged inside the arc grooves 11. The semi-circular discs 12 are attached to the lower surface of the dividing plate 7. The blocking components further include electric push rods 13. The electric push rods 13 are fixedly connected to the outer wall of the inner cylinder 4. The semi-circular discs 12 are fixedly connected to the telescopic ends of the electric push rods 13. Control the telescopic ends of the electric push rods 13 to retract, drive the semi-circular discs 12 to extend into the interior of the inner cylinder 4 through the corresponding arc grooves 11. The two semi-circular discs 12 approach and fit together to block the bottom end of the dividing plate 7, completing the partition between two adjacent grinding chambers 8.

[0056] Specifically, rubber blocks (not shown in the figure) are provided at the arc grooves 11. When the semi-circular discs 12 slide out of the interior of the inner cylinder 4 through the corresponding arc grooves 11, the rubber blocks recover their deformation to close the arc grooves 11, and the kaolin blocks will not run out through the arc grooves 11; at the same time, protective covers and other structures are provided outside the electric push rods 13 to avoid being affected by powder, etc.; and a power supply device can be provided on the outer wall of the inner cylinder 4. The power supply device includes structures such as a storage battery to supply power to the electric push rods 13. The power supply device is a common existing technology and will not be elaborated here.

[0057] During the pulverization process of the kaolin block, control the telescopic end of the electric push rod 13 to retract, drive the semi-circular disk 12 to extend into the interior of the inner cylinder 4 through the corresponding arc groove 11, and the two semi-circular disks 12 approach and fit together to block the bottom end of the dividing disk 7, completing the partition of two adjacent grinding chambers 8.

[0058] Next, start the first motor 23. The first motor 23 drives the rotating shaft 22 fixedly connected to its drive shaft to rotate. With the cooperation of another rotating shaft 22, the inner cylinder 4 tilts and is inverted, and the inner cylinder 4 keeps rotating. The kaolin block tumbles inside the grinding chamber 8 to prevent porcelain from piling up. At the same time, the kaolin block can fully be squeezed, collided with, and rubbed against the grinding medium 9, accelerating the crushing speed, and the powder is discharged from the first round hole 5 on the side wall of the inner cylinder 4.

[0059] At this time, since the two adjacent grinding chambers 8 are partitioned, the kaolin block will not flow back.

[0060] Meanwhile, when the inner cylinder 4 tilts and is inverted, the third round hole 10 will change from the bottom of the corresponding grinding chamber 8 to the top, and the kaolin block piled up at the third round hole 10 will fall off, preventing the third round hole 10 from being blocked.

[0061] After a certain period of time, the inner cylinder 4 returns to the vertical state, and the cover plate 21 is located at the top of the inner cylinder 4 (refer to Figure 5 ), and the first motor 23 stops running. Then, control the telescopic end of the electric push rod 13 to extend, drive the semi-circular disk 12 to slide out of the inner cylinder 4 through the corresponding arc groove 11, remove the blockage of the dividing disk 7, and facilitate the kaolin block to pass through the third round hole 10 and fall into the corresponding grinding chamber 8.

[0062] Considering that the third round hole 10 is prone to accumulation and blockage, a ring groove 14 is opened on the inner wall of the third round hole 10. A slider 15 is slidably arranged inside the ring groove 14. One end of the slider 15 located inside the ring groove 14 is movably inlaid with a ball 20. The ball 20 is provided to improve the smoothness of the slider 15 sliding inside the ring groove 14.

[0063] Moreover, the length of the slider 15 and other structures can be adjusted according to the specific usage situation without affecting the passage of the kaolin block.

[0064] During actual use, affected by the rotation and inclination of the inner cylinder 4, the slider 15 slides inside the ring groove 14, and the slider 15 stirs the kaolin block piled up at the third round hole 10.

[0065] One end of the slider 15 away from the ring groove 14 is provided with a U-shaped groove 16. A rotating rod 17 is fixedly connected inside the U-shaped groove 16. An elastic rod 18 is arranged inside the U-shaped groove 16. A through hole 19 is opened on the elastic rod 18. The elastic rod 18 cooperates with the rotating rod 17 through the through hole 19, and the inner diameter of the through hole 19 is larger than the outer diameter of the rotating rod 17.

[0066] Since the inner diameter of the through hole 19 is larger than the outer diameter of the rotating rod 17, the elastic rod 18 will swing on the rotating rod 17 to expand the agitation area. Moreover, when the semi-circular disk 12 extends into the interior of the inner cylinder 4 through the corresponding arc groove 11, it will touch the elastic rod 18, causing the elastic rod 18 to swing and preventing blockage at the third round hole 10.

[0067] Working principle: Start the first motor 23. The first motor 23 drives the rotating shaft 22 fixedly connected to its drive shaft to rotate. With the cooperation of another rotating shaft 22, mechanisms such as the outer box 1 and the inner cylinder 4 rotate to adjust the inner cylinder 4 to a vertical state, and the cover plate 21 is located at the top of the inner cylinder 4 (refer to Figure 5 ).

[0068] Control the telescopic end of the electric push rod 13 to extend, driving the semi-circular disk 12 to slide out of the inner cylinder 4 through the corresponding arc groove 11, removing the occlusion of the dividing disk 7.

[0069] The operator removes the cover plate 21, pours the large porcelain clay block into the grinding chamber 8 at the uppermost position, and then covers the cover plate 21.

[0070] Start the second motor 24. The second motor 24 drives the first gear 25 to rotate. Since the first gear 25 and the second gear 26 are meshed and connected, the second gear 26 drives the inner cylinder 4 to rotate, and the grinding medium 9 makes a rotary motion. The large porcelain clay block is squeezed, collided with, and rubbed against the grinding medium 9. The large porcelain clay block is broken and becomes medium-sized porcelain clay blocks, and part of the powder is discharged into the outer box 1 through the corresponding first round hole 5; the medium-sized porcelain clay blocks pass through the corresponding third round hole 10 and fall into the grinding chamber 8 at the lower position. The medium-sized porcelain clay blocks are squeezed, collided with, and rubbed against the grinding medium 9. The medium-sized porcelain clay blocks are broken and become small porcelain clay blocks, and part of the powder is discharged into the outer box 1 through the corresponding first round hole 5; the small porcelain clay blocks pass through the corresponding third round hole 10 and fall into the grinding chamber 8 at the lower position. The small porcelain clay blocks are squeezed, collided with, and rubbed against the grinding medium 9. The small porcelain clay blocks are completely broken and become powder, and the powder is discharged into the outer box 1 through the second round hole 6 and the corresponding first round hole 5, achieving high-efficiency crushing layer by layer, improving the manufacturing efficiency, ensuring the quality and uniformity of the powder, and improving the strength for subsequent manufacturing and use of the disc-shaped porcelain insulators.

[0071] During the pulverization of the kaolin block, control the telescopic end of the electric push rod 13 to retract, drive the semi-circular disc 12 to extend into the interior of the inner cylinder 4 through the corresponding arc groove 11, and the two semi-circular discs 12 approach and fit together to block the bottom end of the dividing disc 7, completing the partition of two adjacent grinding chambers 8. Then, start the first motor 23. The first motor 23 drives the rotating shaft 22 fixedly connected to its drive shaft to rotate. With the cooperation of another rotating shaft 22, the inner cylinder 4 tilts and is inverted, and the inner cylinder 4 keeps rotating. The kaolin block tumbles inside the grinding chamber 8 to prevent porcelain from accumulating. At the same time, the kaolin block can fully be squeezed, collided with, and rubbed against the grinding medium 9, accelerating the crushing speed, and the powder is discharged from the first round hole 5 on the side wall of the inner cylinder 4. At this time, since the two adjacent grinding chambers 8 are partitioned, the kaolin block will not flow back.

[0072] At the same time, when the inner cylinder 4 tilts and is inverted, the third round hole 10 will change from the bottom of the corresponding grinding chamber 8 to the top, and the kaolin block accumulated at the third round hole 10 will fall off to prevent blockage at the third round hole 10.

[0073] After a certain period of time, the inner cylinder 4 returns to the vertical state, and the cover plate 21 is located at the top of the inner cylinder 4 (refer to Figure 5 ). Then, control the telescopic end of the electric push rod 13 to extend, drive the semi-circular disc 12 to slide out of the inner cylinder 4 through the corresponding arc groove 11, remove the blockage of the dividing disc 7, and facilitate the kaolin block to pass through the third round hole 10 and fall into the corresponding grinding chamber 8.

[0074] Affected by the rotation and tilt of the inner cylinder 4, the slider 15 slides inside the annular groove 14. The slider 15 stirs the kaolin block accumulated at the third round hole 10. At the same time, since the inner diameter of the through hole 19 is larger than the outer diameter of the rotating rod 17, the elastic rod 18 will swing on the rotating rod 17, and when the semi-circular disc 12 extends into the interior of the inner cylinder 4 through the corresponding arc groove 11, it will touch the elastic rod 18, causing the elastic rod 18 to swing, preventing blockage at the third round hole 10.
