[0021] Please see Figures 1-5 A ceramic screen roller includes a screen roller shaft 1, which includes a seamless steel pipe 2. Segmented ceramic pipes 3 are fitted onto the surface of the seamless steel pipe 2, with two segmented ceramic pipes 3 in contact. A shaft head 4 is located on the left side of the inner cavity of the screen roller shaft 1, and a shaft head 5 is located on the right side. A first bearing seat 6 is fitted onto the left side of the first shaft head 4, and a second bearing seat 7 is fitted onto the right side of the second shaft head 5. By configuring the screen roller shaft 1, seamless steel pipe 2, segmented ceramic pipes 3, shaft head 4, and shaft head 5, the segmented ceramic pipes 3 are fitted onto the seamless steel pipe 2. The surface of the steel pipe 2 directly contacts the material for screening. The segmented ceramic pipe 3 is easy to process, and only the ceramic pipe needs to be replaced after wear. The screen roller shaft 1 can be reused, avoiding the waste of materials when the integrated screen roller is scrapped. The seamless steel pipe 2 serves as an intermediate layer, enhancing the bonding strength between the segmented ceramic pipe 3 and the screen roller shaft 1, while protecting the screen roller shaft 1 from direct wear and extending the service life of the screen roller device. By setting the first bearing seat 6 and the second bearing seat 7, the shaft head 4 and the shaft head 5 are stably supported respectively, facilitating the stable rotation of the screen roller.

[0022] Please see Figure 1 Bearings 8 are fitted onto the surfaces of both shaft head 4 and shaft head 5. A fluid filling hole 9 is provided on the top of both the first bearing seat 6 and the second bearing seat 7. The bearings 8 support shaft head 4 and shaft head 5, facilitating stable rotation. The fluid filling hole 9 allows for periodic injection of lubricating oil, forming an oil film to reduce friction between the bearings 8 and the shaft head, lowering operating temperature, and preventing premature failure due to insufficient lubrication. The lubricating oil can carry away wear particles, reducing impurity accumulation and further improving the reliability of the bearings 8. Lubrication maintenance can be completed without disassembling the bearings 8, simplifying operation and reducing labor and time costs.

[0023] Please see Figure 1 The inner cavities of the first bearing housing 6 and the second bearing housing 7 are both provided with sealing sleeves 10. The two sealing sleeves 10 are respectively fitted onto the surfaces of the first shaft head 4 and the second shaft head 5. By setting the sealing sleeves 10, dust and particles are effectively blocked from entering the bearing housing, thus preventing the bearing 8 from jamming, wearing and corroding due to contamination.

[0024] Please see Figures 1-2Both shaft head 4 and shaft head 5 are fitted with retaining rings 11. One side of the retaining ring 11 contacts the bearing 8. By setting the retaining ring 11, the axial movement of the bearing 8 on the shaft head is restricted, so as to avoid the bearing 8 from shifting due to vibration and impact during the operation of the screen roller, reduce uneven wear and noise, and provide limiting support for the bearing 8.

[0025] Please see Figure 1 A clamping mechanism 12 is installed at the bottom of both the first bearing housing 6 and the second bearing housing 7. The clamping mechanism 12 includes a connecting block 120. The left and right connecting blocks 120 are fixedly connected to the bottom of the first bearing housing 6 and the second bearing housing 7, respectively. A threaded rod 121 is threaded through the surface of the connecting block 120. A movable plate 122 is threadedly fitted onto the surface of the threaded rod 121. A locking block 123 is fixedly connected to one side of the movable plate 122. A support plate 124 is fitted onto the bottom of the connecting block 120. Locking blocks are opened on both sides of the support plate 124. The slot 125 has one side of the locking block 123 extending into the inner cavity of the slot 125. By setting the connecting block 120, threaded rod 121, moving plate 122, locking block 123, support plate 124 and slot 125, the two locking blocks 123 can be brought closer or further apart, so that the locking block 123 and the slot 125 can be engaged. This facilitates the quick and easy fixing and installation of the screen roller device, and also facilitates the disassembly of the screen roller device, bringing convenience to the maintenance and repair of the screen roller device. The support plate 124 is installed on the screening device and can support the screen roller.

[0026] Please see Figure 1 The threads on both sides of the threaded rod 121 have opposite directions of rotation. Both ends of the threaded rod 121 are fixedly connected to knobs 126. By setting the threaded rod 121, when the threaded rod 121 is rotated, the moving plates 122 on both sides move inward or outward at the same time, so that the two locking blocks 123 move closer and further apart. The operation is simple and quick. By setting the knobs 126, the contact area between the operator's fingers and the threaded rod 121 is increased, making it easier to rotate the knobs 126 to drive the threaded rod 121 to rotate.

[0027] In use, the segmented ceramic tube 3 is sleeved on the surface of the seamless steel tube 2 and directly contacts the material for screening. It is connected to the shaft head through an external drive motor, which drives the shaft head to rotate. The shaft head drives the segmented ceramic tube 3 to rotate, thus screening the material. After wear, only the segmented ceramic tube 3 needs to be replaced. The screen roller shaft 1 can be reused. Lubricating oil is injected into the inner cavity of the liquid inlet 9. The lubricating oil enters the liquid inlet 9 and contacts the bearing 8 to lubricate the bearing 8. The sealing sleeve 10 effectively blocks dust and particles from entering the bearing seat, preventing the bearing 8 from jamming, wearing and corroding due to contamination. The retaining ring 11 restricts the axial movement of the bearing 8 on the shaft head, preventing the bearing 8 from shifting due to vibration and impact during the operation of the screen roller.

[0028] Rotating the knob 126 causes the threaded rod 121 to rotate, and the threaded rod 121 causes the moving plate 122 to move laterally. The moving plate 122 causes the locking block 123 to move, so that the two locking blocks 123 move away from each other, and the locking block 123 separates from the locking groove 125. The connecting block 120 moves upward to separate from the support plate 124, thereby disassembling the screen roller device.

[0029] In summary, this ceramic screen roller, by setting up a screen roller shaft 1, a seamless steel pipe 2, a segmented ceramic pipe 3, a shaft head 1 4, and a shaft head 2 5, solves the problem that when the screen roller shaft and roller skin are set up as a whole, the roller skin directly contacts the material, which is prone to wear due to friction, impact, and corrosion. After the screen roller wears out, it needs to be replaced as a whole, which increases the manufacturing cost.
