Description

Technical Field

[0001] The utility model relates to the field of cyclone accessories, in particular to a cyclone ceramic lining. Background Art

[0002] A hydrocyclone is a common separation and classification device that typically operates on the principle of centrifugal sedimentation. When the two-phase mixture to be separated enters the hydrocyclone tangentially from its periphery at a constant pressure, it generates intense three-dimensional, elliptical, highly rotating, shearing turbulence. Due to the size difference between coarse and fine particles, they are subject to varying degrees of centrifugal force, centripetal buoyancy, and fluid drag. As a result of centrifugal sedimentation, the majority of coarse particles are discharged through the hydrocyclone's underflow outlet, while the majority of fine particles are discharged through the overflow pipe, achieving the desired separation and classification.

[0003] To improve the practical performance of a cyclone, an additional lining is usually added to the inner wall of the cyclone. For example, Chinese patent application number CN201720345855.7 provides a cyclone ceramic lining, including a wear-resistant ceramic component with a hardness of HRA83-85 covering the inner wall of the cyclone. The inner wall of the cyclone is provided with a snap-on connection component for snap-on connection with the wear-resistant ceramic component. The bottom of the wear-resistant ceramic component is provided with a snap-on hole that matches the snap-on connection component. The snap-on connection component is a dovetail-shaped elongated protrusion with a wider top and a narrower bottom. The snap-on hole is a dovetail-shaped elongated hole with a larger inner side and a smaller outer side.

[0004] The above technical solution involves a cyclone equipped with a ceramic lining. However, during operation, static electricity is generated by the friction between the material and the lining, and it cannot be discharged in time. The static electricity accumulates in the cyclone and easily absorbs tiny particles in the material, reducing the separation quality and efficiency, and there is a risk of static electricity causing fire.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See Figure 1 A cyclone ceramic lining includes a column 4 and a straight section 8. The top of the column 4 is connected to the overflow conduit 1 through a packing sealing disk 2. A slurry inlet pipe 3 is installed on the side of the top of the column 4. The bottom of the column 4 is connected to the straight section 8 through a sealing flange 9. A cone 7 is provided below the straight section 8. A bottom flow port 6 is installed at the bottom of the cone 7. Conductive ceramic lining gaskets 5 are installed on the inner walls of the column 4, the straight section 8 and the cone 7.

[0022] See Figure 1 A sealing gasket 10 is provided in the middle of the sealing flange 9. This arrangement can improve the sealing and reliability of the sealing flange 9 and prevent the sealing flange 9 from leaking.

[0023] See Figure 2 The conductive ceramic lining gasket 5 includes a ceramic sheet substrate 501, one side of the ceramic sheet substrate 501 is fixedly connected to the column 4, the straight section 8, and the cone 7 respectively, and the other side surface of the conductive ceramic lining gasket 5 is paved with a conductive embedded sheet 502, and a conductive wire 503 is arranged in the ceramic sheet substrate 501. This arrangement makes it easier for the conductive embedded sheet 502 to gather static electricity generated by the friction between the conductive ceramic lining gasket 5 and the material.

[0024] See Figure 2 The surface of the conductive inner embedded sheet 502 is arc-shaped, and the arc-shaped top surface of the conductive inner embedded sheet 502 is higher than the surface of the ceramic substrate 501. This arrangement makes it easy to utilize the principle of tip charge collection to gather static electricity to the conductive inner embedded sheet 502 and discharge it.

[0025] See Figure 2Lead cables 504 are provided in the column 4, the straight section 8, and the cone 7. The lead cables 504 are electrically connected to each conductive embedded sheet 502 through a conductive wire 503. This arrangement facilitates the discharge of accumulated static electricity to the outside of the cyclone via the conductive wire 503 and the lead cables 504, thereby preventing static electricity from accumulating on the conductive ceramic liner 5.

[0026] See Figure 2 The lead-in cable 504 is electrically connected to the conductive hammer block 505. This arrangement facilitates the grounding of the conductive hammer block 505, thereby conducting static electricity into the ground and achieving the purpose of safely discharging static electricity. At the same time, the conductive hammer block 505 can also keep the end of the lead-in cable 504 outside the cyclone, making it convenient for workers to perform grounding operations on it.

[0027] See Figure 2 The conductive hammer block 505 is made of stainless steel, which makes it easy to bury the conductive hammer block 505 underground to guide static electricity while still maintaining an extremely long service life.

[0028] See Figure 2 The power cable 504 and the conductive wire 503 are both armored cables. This arrangement can ensure the insulation and waterproof performance of the power cable 504 and the conductive wire 503, thereby maintaining their service life in a poor working environment.

[0029] Working principle: When using this device, the material to be diverted is injected through the slurry inlet pipe 3. Under the action of high-speed spiral force, the material is spirally diverted in the column 4, straight section 8 and cone 7. The material with higher density is discharged through the bottom flow port 6, and the material with lower density moves toward the central axis and forms an upward-moving inner vortex at the center of the axis, and then is discharged from the overflow conduit 1, thus achieving the purpose of two-phase separation. In this process, the rotating material rubs with the conductive ceramic lining gasket 5 to generate static electricity. After the static electricity is concentrated by the conductive embedded sheet 502, it is guided to the outside of the cyclone through the conductive wire 503 and the lead cable 504, avoiding the accumulation of static electricity inside the cyclone, thereby avoiding the risk of causing static electricity fire. At the same time, it can also prevent the static electricity on the conductive ceramic lining gasket 5 from adsorbing tiny particles in the material, thereby improving the quality and efficiency of the cyclone diversion material.
