[0001] The utility model relates to cyclone technical field especially relates to a cyclone magnetic lining. BACKGROUND

[0002] Cyclone is a kind of equipment that adopts centrifugal force to grade, and the ore pulp enters cyclone by pump, due to the pumping kinetic energy, the ore pulp forms high-speed rotary motion in the inside of cyclone, on the radial section, the ore pulp is guided by cyclone feed body and forms extremely fast tangential velocity, and the centripetal force is generated from the tangential velocity, and the reaction is centrifugal force. The coarse heavy mineral particles are subjected to large centrifugal force, thereby close to the inner wall of cyclone, and finally discharged by sand trap; the fine light mineral particles are subjected to large centripetal buoyancy, thereby close to the center of cyclone, and finally discharged by overflow. Thus, the coarse and fine particles and heavy and light minerals are graded and separated.

[0003] However, in the prior art, since the cyclone centrifugal force depends on the tangential velocity, the higher the classification accuracy needs the greater tangential velocity; at the same time, the cyclone often serves the first stage and the second stage grinding classification process, especially the grinding classification of iron ore, the feed size is large, the ore hardness is high, and the material is sharp. Under the comprehensive influence of high flow rate, large particle size and high hardness of the ore pulp in the cyclone, the wear rate of the traditional cyclone lining is fast, which seriously affects the service life of the cyclone and increases the maintenance cost of the equipment. SUMMARY

[0004] To solve the above problems, the application provides a cyclone magnetic lining, which is provided with a lower cover lining, a barrel body lining, a cone body lining and an underflow port lining, and is sequentially attached to the inner wall of the cyclone by magnetism. The lower cover lining, the barrel body lining, the cone body lining and the underflow port lining are provided in a split structure.

[0005] In one embodiment, the lower cover lining is divided into a plurality of sectorial parts with the overflow port as the center, and is combined by splicing.

[0006] In one embodiment, the barrel body lining and the cone body lining are divided into a plurality of parts along the axial direction of the cyclone and are combined by splicing.

[0007] In one embodiment, the splicing part of the lower cover lining, the barrel body lining and the cone body lining is connected by a mortise and tenon structure, and the mortise and tenon structure includes a splicing protrusion arranged on the side surface of the lining and a splicing groove opposite to the splicing protrusion.

[0008] In one embodiment, the lower cover lining, the barrel body lining, the cone body lining and the underflow port lining are made of permanent magnet.

[0009] In one embodiment, the lower cover liner is disc-shaped, the barrel liner is cylindrical, and the cone liner and the underflow port liner are conical.

[0010] In one embodiment, the splicing protrusions can be arc-shaped or square-shaped.

[0011] The utility model discloses the beneficial effect lies in:

[0012] The cyclone magnetic lining of the application is provided with a lower cover liner, a barrel liner, a cone liner and an underflow port liner, which are sequentially adsorbed on the inner wall of the cyclone through magnetism, and the lower cover liner, the barrel liner, the cone liner and the underflow port liner are provided in a split structure. The lower cover liner, the barrel liner, the cone liner and the underflow port liner are adsorbed on the inner side of the steel shell of the cyclone through their magnetic properties, ensuring that the liners are stable and do not fall off, and the inner side adsorbs the magnetic particles in the ore pulp, which form a protective layer on the surface of the liners. When the particles in the subsequent ore pulp flow through, the ore pulp will preferentially contact the particle protective layer, thereby reducing direct abrasion of the liner base material, effectively prolonging the service life of the cyclone, and the lower cover liner, the barrel liner, the cone liner and the underflow port liner are provided in a split structure, that is, the four parts can be individually removed. Since the stress conditions of different parts inside the cyclone are different, the abrasion conditions are also different, and through the split structure, when a certain part is damaged, it can be individually replaced without the need to disassemble the entire magnetic lining of the cyclone. By accurately replacing the worn parts, the entire magnetic lining is avoided from being scrapped due to local wear, the overall service life of the cyclone is prolonged, and the maintenance cost and time are greatly reduced.

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0023] like Figures 1-3 As shown, a hydrocyclone magnetic liner is provided, comprising a lower cover liner 1, a barrel liner 2, a cone liner 3, and an underflow inlet liner 4, which are sequentially magnetically adsorbed onto the inner wall of the hydrocyclone 5. The lower cover liner 1, the barrel liner 2, the cone liner 3, and the underflow inlet liner 4 are configured as separate structures.

[0024] Specifically, the slurry enters the hydrocyclone 5 at a certain speed and pressure. The centrifugal force generated by the rotation separates particles of different densities. Heavier particles, subjected to greater centrifugal force, move along the inner linings 2 (barrel) and 3 (conical) of the hydrocyclone 5 towards the underflow lining 4, and are eventually discharged from the underflow outlet. Lighter particles continue to flow upwards and are eventually discharged from the overflow outlet of the hydrocyclone 5. The lower cover lining 1, barrel lining 2, conical lining 3, and underflow lining 4, through their magnetic properties, adhere to the inner steel shell of the hydrocyclone 5 on their outer sides, ensuring the linings are stable and do not detach. On their inner sides, they adsorb magnetic particles from the slurry, forming a protective layer on the lining surface. When particles in the subsequent slurry flow through, the slurry will preferentially contact the particle protective layer, thereby reducing direct abrasion of the inner lining substrate and effectively extending the service life of the hydrocyclone 5. The lower cover lining 1, the barrel inner lining 2, the cone inner lining 3, and the underflow outlet lining 4 are designed as separate structures, that is, these four parts can be removed individually. Since the stress conditions and wear conditions of different parts inside the hydrocyclone 5 are different, the separate structure allows for individual replacement when a part is damaged, without disassembling the entire magnetic lining of the hydrocyclone 5. By accurately replacing worn parts, the scrapping of the entire magnetic lining due to local wear is avoided, extending the overall service life of the hydrocyclone 5 and greatly reducing maintenance costs and time.

[0025] like Figure 2As shown, the lower cover liner 1 is divided into multiple fan-shaped parts with the overflow port as the center, and is combined by splicing.

[0026] Specifically, the overflow port of the cyclone 5 is the key part for discharging fine particles and liquid. The lower cover liner 1 is divided around the overflow port, which can ensure that the liner is tightly attached to the shell around the overflow port, avoiding fluid leakage. Figure 1 、 3 As shown, after being divided into multiple fan-shaped parts, the manufacturing process of the liner can be simpler and more efficient. At the same time, the splicing combination method simplifies the installation process, reduces the installation difficulty and time cost.

[0027] As shown in Figure 1 、 4 5, the barrel liner 2 and the cone liner 3 are divided into multiple parts along the axial direction of the cyclone 5 and are combined by splicing.

[0028] Specifically, the barrel liner 2 and the cone liner 3 are divided into multiple parts along the axial direction of the cyclone 5. This design can be flexibly adjusted according to different specifications and diameter sizes of the cyclone 5, ensuring that the liner is tightly attached to the steel shell of the cyclone 5. By splicing different numbers of axial division parts, the liner can be adapted to cyclones 5 of various specifications, eliminating the need to produce a separate liner for each size of cyclone, thereby reducing production costs.

[0029] As shown in Figure 1 、 2 The splicing part of the lower cover liner 1, the barrel liner 2, and the cone liner 3 is connected by a mortise and tenon structure 6, which includes a splicing protrusion 61 provided on the side surface of the liner and a splicing groove 62 opposite to the splicing protrusion 61.

[0030] Specifically, the splicing protrusion 61 is provided on the side surface of the liner, which can be circular or square. The splicing groove 62 is provided opposite to the splicing protrusion 61, used to accommodate and fix the splicing protrusion 61, forming a tight connection. The design of the mortise and tenon structure 6 ensures that the splicing protrusion 61 and the splicing groove 62 are strictly matched in shape and size, thereby ensuring accurate docking between the liners and avoiding problems such as liner loosening or misalignment due to inaccurate docking. Through the connection of the mortise and tenon structure 6, a tight contact surface is formed between adjacent liners, improving the docking tightness and avoiding the lifting of the liner by the ore pulp.

[0031] As shown in Figure 1 The lower cover liner 1, the barrel liner 2, the cone liner 3, and the underflow port liner 4 are made of permanent magnets.

[0032] Specifically, the permanent magnet liner can generate a stable magnetic field. The permanent magnet adsorbs magnetic particles in the slurry to form a protective layer, so that particles in the slurry and other fluids preferentially contact the protective layer instead of directly abrading the liner. This helps to extend the service life of the liner and reduce the frequency of replacement and maintenance costs.

[0033] like ​ As shown, the lower cover liner 1 is disc-shaped, the barrel liner 2 is cylindrical, and the conical liner 3 and the bottom outlet liner 4 are conical.

[0034] The beneficial effects of this application compared with the prior art are as follows:

[0035] This application discloses a magnetic liner for a hydrocyclone, comprising a lower cover liner 1, a barrel liner 2, a conical liner 3, and an underflow inlet liner 4, which are sequentially magnetically adsorbed onto the inner wall of a hydrocyclone 5. The lower cover liner 1, barrel liner 2, conical liner 3, and underflow inlet liner 4 are separate structures. Due to their magnetic properties, the lower cover liner 1, barrel liner 2, conical liner 3, and underflow inlet liner 4 are magnetically adsorbed on the outer side to the inner side of the steel shell of the hydrocyclone 5, ensuring the liner is stable and does not fall off. The inner side adsorbs magnetic particles from the slurry, which form a protective layer on the liner surface. When particles in the subsequent slurry flow through, the slurry will preferentially contact the particle protective layer, thereby reducing direct abrasion of the inner lining substrate and effectively extending the service life of the hydrocyclone 5. The lower cover lining 1, the barrel inner lining 2, the cone inner lining 3, and the underflow outlet lining 4 are designed as separate structures, that is, these four parts can be removed individually. Since the stress conditions and wear conditions of different parts inside the hydrocyclone 5 are different, the separate structure allows for individual replacement when a part is damaged, without disassembling the entire magnetic lining of the hydrocyclone 5. By accurately replacing worn parts, the scrapping of the entire magnetic lining due to local wear is avoided, extending the overall service life of the hydrocyclone 5 and greatly reducing maintenance costs and time.
