[0001] This invention relates to the field of porcelain insulator manufacturing technology, and in particular to a method for manufacturing a high-strength disc-shaped porcelain insulator. Background Technology

[0002] High-strength disc-type suspension porcelain insulators are the most widely used and important type of line insulators. They are generally used in high-voltage overhead lines for insulation and fixation. They are mainly composed of iron caps, steel feet, porcelain parts with shed skirts, and adhesive. Porcelain insulators are an important component of transmission lines, serving as both electrical insulation components and important structural supports. The insulation and mechanical properties of porcelain insulators, as well as the rationality of their configuration, directly affect the safe and stable operation of the line.

[0003] In the manufacturing process of high-strength disc-type suspension porcelain insulators, porcelain clay blocks need to be crushed into powder. In existing technology, porcelain clay blocks are usually placed in a stirred mill, where the grinding media inside the mill cylinder crushes and grinds the porcelain clay blocks as a whole. This grinding process is time-consuming and affects the manufacturing efficiency of high-strength disc-type porcelain insulators.

[0004] Therefore, it is necessary to propose a manufacturing method for high-strength disc-shaped porcelain insulators to solve the above problems. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a method for manufacturing a high-strength disc-shaped porcelain insulator, comprising the following steps:

[0007] S1. Layering: Place the clay blocks into the crushing device and crush and sieve them step by step from top to bottom.

[0008] S2. Turning over: The crushing device is tilted and inverted, causing the porcelain clay blocks to turn over and preventing the porcelain clay blocks from flowing back.

[0009] The crushing device includes an outer casing, and an inner cylinder for placing clay blocks is provided at the top of the outer casing. A plurality of dividing discs are fixedly connected inside the inner cylinder, and the dividing discs divide the interior of the inner cylinder into multiple grinding chambers. Grinding media are provided inside the grinding chambers. Several third circular holes are opened on the dividing discs, and the size of the third circular holes on each dividing disc decreases from top to bottom. Barrier components are provided on both sides below the dividing discs. The barrier components include arc grooves and semi-circular discs. The arc grooves are opened on the side walls of the inner cylinder, and the semi-circular discs are slidably disposed inside the arc grooves and are attached to the lower surface of the dividing discs.

[0010] S3. Discharge: The clay blocks are crushed into powder.

[0011] Preferably, the inner cylinder has a plurality of first circular holes on its side wall and a plurality of second circular holes on its bottom, the inner diameter of the second circular holes being the same as the inner diameter of the first circular holes.

[0012] Preferably, the barrier assembly further includes an electric push rod, which is fixedly connected to the outer wall of the inner cylinder, and the semi-circular disk is fixedly connected to the telescopic end of the electric push rod.

[0013] Preferably, an annular groove is formed on the inner wall of the third circular hole, and a slider is slidably disposed inside the annular groove.

[0014] Preferably, the end of the slider away from the annular groove has a U-shaped groove, a rotating rod is fixedly connected inside the U-shaped groove, an elastic rod is provided inside the U-shaped groove, and a through hole is provided on the elastic rod, which cooperates with the rotating rod through the through hole.

[0015] Preferably, the inner diameter of the through hole is larger than the outer diameter of the rotating rod.

[0016] Preferably, a ball bearing is movably embedded at one end of the slider located inside the annular groove.

[0017] Preferably, the top of the outer casing has a through groove, the inner cylinder is rotatably disposed inside the through groove, and a drive assembly for rotating the inner cylinder is disposed on the outside of the outer casing. The drive assembly includes a second motor, a first gear and a second gear. The second motor is fixedly connected to the outer wall of the outer casing, the first gear is fixedly connected to the drive shaft of the second motor, and the second gear is fixedly connected to the inner cylinder. The first gear and the second gear are meshed together.

[0018] Preferably, the top of the inner cylinder is fitted with a cover plate.

[0019] Preferably, the outer casing is provided with a frame, and rotating shafts are fixedly connected to both outer walls of the outer casing. The end of the rotating shaft away from the outer casing is rotatably connected to the frame. A first motor is fixedly connected to the frame, and one of the rotating shafts is fixedly connected to the drive shaft of the first motor.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. The present invention adopts a step-by-step crushing method for porcelain clay blocks, and when the crushing device drives the porcelain clay blocks to turn over, it prevents the porcelain clay blocks from flowing back, avoids reverse screening, and improves the manufacturing efficiency of high-strength disc-shaped porcelain insulators.

[0022] 2. By setting up an inner cylinder, grinding chamber and barrier components, the process is to crush the material in layers and at each stage in a high-efficiency manner, thereby improving manufacturing efficiency and ensuring the quality and uniformity of the powder. This enhances the strength of the disc-shaped porcelain insulator in subsequent manufacturing and use. At the same time, the inner cylinder is tilted and inverted, and the two adjacent grinding chambers are separated, so the porcelain clay blocks will not flow back.

[0023] 3. When the inner cylinder is tilted or inverted, and continues to rotate, the clay blocks are turned over inside the grinding chamber, preventing the porcelain from accumulating. At the same time, the clay blocks can fully compress, collide, and rub against the grinding media, accelerating the crushing speed.

[0024] 4. When the inner cylinder is tilted or inverted, the third round hole will change from the bottom to the top of the corresponding grinding chamber, and the porcelain clay block accumulated at the third round hole will fall off, thus avoiding blockage at the third round hole;

[0025] 5. Due to the rotation and tilt of the inner cylinder, the slider slides inside the annular groove. The slider agitates the porcelain clay blocks accumulated at the third circular hole. The elastic rod swings on the rotating rod to expand the agitation area. When the semi-circular disk passes through the corresponding arc groove and extends into the inner cylinder, it will touch the elastic rod, causing the elastic rod to swing and preventing blockage at the third circular hole.

[0039] This invention provides, for example Figures 1-12 The method for manufacturing a high-strength disc-shaped porcelain insulator, as shown, includes the following steps:

[0040] S1. Layering: Place the clay blocks into the crushing device and crush and sieve them step by step from top to bottom.

[0041] S2. Tumbling: The crushing device is tilted and inverted, causing the porcelain clay blocks to tumble and preventing them from flowing back. Since it is a step-by-step crushing and screening process, the backflow of the porcelain clay blocks is prevented when the crushing device tumbles the porcelain clay blocks, thus avoiding reverse screening.

[0042] S3. Discharge: The clay blocks are crushed into powder.

[0043] This invention employs a step-by-step crushing method for porcelain clay blocks. Furthermore, by preventing the porcelain clay blocks from flowing back during the crushing process, reverse screening is avoided, thereby improving the manufacturing efficiency of high-strength disc-shaped porcelain insulators.

[0044] In its specific configuration, the crushing device includes an outer casing 1, with a frame 2 mounted on the outside of the outer casing 1. Rotating shafts 22 are fixedly connected to both outer walls of the outer casing 1. The ends of the rotating shafts 22 furthest from the outer casing 1 are 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 drive shaft of the first motor 23. The first motor 23 drives the rotating shaft 22 fixedly connected to its drive shaft to rotate, and with the cooperation of the other rotating shaft 22, the outer casing 1 rotates.

[0045] In actual use, a discharge suction device can be connected to the outer casing 1. The suction device includes a material pump and other structures, which is used to promptly remove the powder after the clay blocks are crushed.

[0046] The outer casing 1 has an inner cylinder 4 at its top for holding clay blocks. A through groove 3 is formed at the top of the outer casing 1, and the inner cylinder 4 is rotatably positioned inside the through groove 3. A drive assembly for rotating the inner cylinder 4 is located outside the outer casing 1. The drive 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 casing 1, the first gear 25 is fixedly connected to the drive shaft of the second motor 24, and the second gear 26 is fixedly connected to the inner cylinder 4. The first gear 25 and the second gear 26 are meshed together. The second motor 24 drives the first gear 25 to rotate, and because the first gear 25 and the second gear 26 are meshed together, the second gear 26 drives the inner cylinder 4 to rotate.

[0047] Considering that in the existing technology, porcelain clay blocks are usually put into a mixing mill to crush and grind the porcelain clay blocks as a whole, which takes a long time, in order to improve manufacturing efficiency, a dividing plate 7 is fixedly connected inside the inner cylinder 4. Multiple dividing plates 7 are provided, and the dividing plates 7 divide the inside of the inner cylinder 4 into multiple grinding chambers 8, which facilitates step-by-step crushing. The top of the inner cylinder 4 is fitted with a cover plate 21.

[0048] The grinding chamber 8 is equipped with multiple grinding media 9. The clay blocks are squeezed, collided and rubbed with the grinding media 9 to achieve the effect of crushing.

[0049] The sub-disc 7 has several third circular holes 10, and the size of the third circular holes 10 on each sub-disc 7 decreases from top to bottom.

[0050] Several first circular holes 5 are provided on the side wall of the inner cylinder 4, and several second circular holes 6 are provided on the bottom of the inner cylinder 4. The inner diameter of the second circular holes 6 is the same as the inner diameter of the first circular holes 5. The inner diameters of the first circular holes 5 and the second circular holes 6 are smaller than the inner diameter of the smallest third circular hole 10.

[0051] In actual use, the first motor 23 is started, which drives the rotating shaft 22, which is fixedly connected to its drive shaft, to rotate. With the cooperation of the other rotating shaft 22, the outer casing 1, inner cylinder 4, and other mechanisms rotate, adjusting the inner cylinder 4 to a vertical position, and the cover plate 21 is located at the top of the inner cylinder 4 (see reference). Figure 5 ).

[0052] The operator removes the cover plate 21, pours the large clay block into the grinding chamber 8 located at the top, and then closes the cover plate 21.

[0053] The second motor 24 is started, which drives the first gear 25 to rotate. Since the first gear 25 and the second gear 26 are meshed, the second gear 26 drives the inner cylinder 4 to rotate, and the grinding media 9 rotates. Large porcelain clay blocks are squeezed, collided, and rubbed with the grinding media 9. The large porcelain clay blocks are broken into medium porcelain clay blocks, and some powder is discharged into the outer box 1 through the corresponding first round hole 5. The medium porcelain clay blocks pass through the corresponding third round hole 10 and fall into the grinding chamber 8 at the lower position. The medium porcelain clay blocks are squeezed, collided, and rubbed with the grinding media 9. The medium porcelain clay blocks are broken into small porcelain clay blocks, and some 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, and rubbed with the grinding media 9. The small porcelain clay blocks are completely broken into powder, and the powder is discharged into the outer box 1 through the second round hole 6 and the corresponding first round hole 5.

[0054] Multiple grinding chambers are set up to achieve efficient, layered, and step-by-step crushing, which improves manufacturing efficiency, ensures the quality and uniformity of the powder, and enhances the strength of the disc-shaped porcelain insulator in subsequent manufacturing and use.

[0055] Considering that the clay blocks are easily accumulated in the lower half of the grinding chamber 8 due to gravity when crushing is only achieved by rotating the inner cylinder 4, the inner cylinder 4 can be tilted or inverted by the outer box 1 to achieve the turning of the clay blocks. However, the present invention adopts a layered crushing method. When the inner cylinder 4 is tilted or inverted, the clay blocks are easy to flow back, that is, pass through the third circular hole 10 on the same dividing plate 7 in the opposite direction, which affects the efficiency of layered crushing. In order to complete the separation of the two adjacent grinding chambers 8, a blocking component is provided on both sides below the dividing plate 7. The blocking component includes an arc groove 11 and a semi-circular disk 12. The arc groove 11 is opened on the side wall of the inner cylinder 4. The arc groove 11 has a small thickness. The semi-circular disk 12 is slidably disposed inside the arc groove 11 and is attached to the lower surface of the dividing plate 7. The blocking component also includes an electric push rod 13. The electric push rod 13 is fixedly connected to the outer wall of the inner cylinder 4, and the semi-circular disk 12 is fixedly connected to the telescopic end of the electric push rod 13. The telescopic end of the control electric push rod 13 is retracted, which drives the semi-circular disk 12 to extend into the inner cylinder 4 through the corresponding arc groove 11. The two semi-circular disks 12 come close together and block the bottom of the dividing disk 7, thus completing the separation of the two adjacent grinding chambers 8.

[0056] Specifically, a rubber block (not shown in the figure) is provided at the arc groove 11. When the semi-circular disk 12 slides out from the inside of the inner cylinder 4 through the corresponding arc groove 11, the rubber block restores its deformation and closes the arc groove 11, preventing the clay block from running out of the arc groove 11. At the same time, the electric push rod 13 is provided with a protective cover and other structures to avoid being affected by powder and other substances. A power supply device, including a battery and other structures, can be provided on the outer wall of the inner cylinder 4 to supply power to the electric push rod 13. The power supply device is a common existing technology and will not be described in detail here.

[0057] During the crushing of porcelain clay blocks, the telescopic end of the electric push rod 13 is retracted, which drives the semi-circular disk 12 to extend into the inner cylinder 4 through the corresponding arc groove 11. The two semi-circular disks 12 come close together and cover the bottom of the dividing disk 7, thus completing the separation of the two adjacent grinding chambers 8.

[0058] Next, the first motor 23 is started, which 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 inverts, while the inner cylinder 4 continues to rotate. The porcelain clay blocks are turned over inside the grinding chamber 8 to prevent the porcelain from accumulating. At the same time, the porcelain clay blocks can fully squeeze, collide and rub with the grinding media 9 to accelerate the crushing speed. The powder is discharged from the first round hole 5 on the side wall of the inner cylinder 4.

[0059] At this point, since the two adjacent grinding chambers 8 are now separated, the clay blocks will not flow back.

[0060] At the same time, when the inner cylinder 4 is tilted or inverted, the third round hole 10 will change from the bottom to the top of the corresponding grinding chamber 8, and the porcelain clay block accumulated at the third round hole 10 will fall off, thus avoiding blockage at the third round hole 10.

[0061] After a certain period of time, the inner cylinder 4 returns to a vertical position, and the cover plate 21 is located at the top of the inner cylinder 4 (refer to...). Figure 5 Then, the first motor 23 stops running. Next, the telescopic end of the control electric push rod 13 extends, driving the semi-circular disk 12 to slide outward from the inside of the inner cylinder 4 through the corresponding arc groove 11, releasing the obstruction of the dividing disk 7, so that the porcelain clay block can pass through the third circular hole 10 and fall into the corresponding grinding chamber 8.

[0062] Considering that blockage is prone to occur at the third circular hole 10, an annular groove 14 is provided on the inner wall of the third circular hole 10. A slider 15 is slidably arranged inside the annular groove 14. A ball bearing 20 is movably embedded at one end of the slider 15 inside the annular groove 14. The ball bearing 20 is provided to improve the smoothness of the slider 15 sliding inside the annular groove 14.

[0063] Furthermore, the length of structures such as slider 15 can be adjusted according to specific usage conditions, without affecting the passage of clay blocks.

[0064] In actual use, due to the rotation and tilt of the inner cylinder 4, the slider 15 slides inside the annular groove 14, and the slider 15 stirs the porcelain clay blocks accumulated at the third circular hole 10.

[0065] A U-shaped groove 16 is provided at the end of the slider 15 away from the annular groove 14. A rotating rod 17 is fixedly connected inside the U-shaped groove 16. An elastic rod 18 is provided inside the U-shaped groove 16. A through hole 19 is provided on the elastic rod 18. The elastic rod 18 cooperates with the rotating rod 17 through the through hole 19. 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 stirring area. When the semi-circular disk 12 passes through the corresponding arc groove 11 and extends into the inner cylinder 4, it will touch the elastic rod 18, causing the elastic rod 18 to swing, thus avoiding blockage at the third circular hole 10.

[0067] Working principle: The first motor 23 is started, driving the rotating shaft 22, which is fixedly connected to its drive shaft, to rotate. With the cooperation of another rotating shaft 22, the outer casing 1, inner cylinder 4, and other mechanisms rotate, adjusting the inner cylinder 4 to a vertical position, with the cover plate 21 located at the top of the inner cylinder 4 (see reference). Figure 5 ).

[0068] The extension end of the control electric push rod 13 extends, driving the semi-circular disk 12 to slide outward from the inside of the inner cylinder 4 through the corresponding arc groove 11, thus removing the obstruction to the dividing disk 7.

[0069] The operator removes the cover plate 21, pours the large clay block into the grinding chamber 8 located at the top, and then closes the cover plate 21.

[0070] The second motor 24 is started, which drives the first gear 25 to rotate. Since the first gear 25 and the second gear 26 are meshed, the second gear 26 drives the inner cylinder 4 to rotate, causing the grinding media 9 to rotate. Large porcelain clay blocks are squeezed, collided, and rubbed against the grinding media 9, breaking them into medium-sized porcelain clay blocks. Some of the powder is discharged into the outer casing 1 through the corresponding first circular hole 5. The medium-sized porcelain clay blocks pass through the corresponding third circular hole 10 and fall into the grinding chamber 8 below, where they are squeezed and rubbed against the grinding media 9. Through impact and friction, the medium-sized porcelain clay blocks are broken into smaller pieces, and some of the powder is discharged into the outer casing 1 through the corresponding first circular hole 5. The small porcelain clay blocks pass through the corresponding third circular hole 10 and fall into the grinding chamber 8 below. The small porcelain clay blocks are squeezed, collided, and rubbed with the grinding media 9, and are completely broken into powder. The powder is discharged into the outer casing 1 through the second circular hole 6 and the corresponding first circular hole 5. This layered and step-by-step high-efficiency crushing improves manufacturing efficiency, ensures the quality and uniformity of the powder, and enhances the strength of the disc-shaped porcelain insulator in subsequent manufacturing and use.

[0071] During the crushing process of porcelain clay blocks, the telescopic end of the control electric push rod 13 is retracted, driving the semi-circular disk 12 to extend into the inner cylinder 4 through the corresponding arc groove 11. The two semi-circular disks 12 come close together, blocking the bottom of the dividing disk 7, thus isolating the two adjacent grinding chambers 8. Next, the first motor 23 is started, driving 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 inverts, while maintaining its own rotation. The porcelain clay blocks are turned over inside the grinding chamber 8, preventing porcelain from accumulating. At the same time, the porcelain clay blocks can fully compress, collide, and rub against the grinding media 9, accelerating the crushing speed. 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 isolated, the porcelain clay blocks will not flow back.

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

[0073] After a certain period of time, the inner cylinder 4 returns to a vertical position, and the cover plate 21 is located at the top of the inner cylinder 4 (refer to...). Figure 5 Next, the telescopic end of the electric push rod 13 extends, driving the semi-circular disk 12 to slide outward from the inside of the inner cylinder 4 through the corresponding arc groove 11, thus removing the obstruction of the dividing disk 7 and allowing the clay block to pass through the third circular hole 10 and fall into the corresponding grinding chamber 8.

[0074] Due to the rotation and tilt of the inner cylinder 4, the slider 15 slides inside the annular groove 14. The slider 15 agitates the porcelain clay blocks accumulated at the third circular 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. When the semi-circular disk 12 passes through the corresponding arc groove 11 and extends into the inner cylinder 4, it will touch the elastic rod 18, causing the elastic rod 18 to swing, thus preventing blockage at the third circular hole 10.
