Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, specifically to a protective magnetic conductive module and a magnetic separator. Background Technology

[0002] A magnetic separator is a device that uses electromagnetic principles to remove iron. One existing type of magnetic separator includes a body with a magnetic separation channel inside. A magnetic guiding module is installed within the magnetic separation channel. The magnetic guiding module includes a central shaft and multiple layers of magnetically guided mesh sheets mounted on the central shaft. The multiple layers of magnetically guided mesh sheets are tightly stacked. An excitation coil is arranged around the magnetic separation channel on the body. The magnetic guiding module is movably mounted on the body, and a vibrating motor is installed on the body to vibrate the magnetic guiding module. The working process of this magnetic separator is divided into a magnetic separation stage and an iron removal stage. During the magnetic separation stage, the excitation coil is energized to generate a magnetic field, magnetizing the magnetically guided mesh sheets. When the material passes through the magnetic separation channel, the ferromagnetic substances in the material are attracted to the magnetically guided mesh sheets, while the remaining material flows out. During the iron removal stage, the power supply to the excitation coil is stopped, the magnetically guided mesh sheets demagnetize, and under the action of the vibrating motor, the magnetic guiding module vibrates up and down, causing the ferromagnetic substances attracted to the magnetically guided mesh sheets to fall off and be discharged from the magnetic separation channel.

[0003] This type of magnetic separator is widely used for iron removal and purification of materials. Some materials require high purity. To prevent contamination from debris generated by friction between the material and the magnetic mesh, a wear-resistant protective layer is usually installed on the magnetic mesh. However, when multiple layers of magnetic mesh are stacked together in the magnetic module, vibration can cause collisions and friction between the meshes, damaging the protective layer. This debris can also contaminate the material, affecting its purity. Furthermore, the tightly packed magnetic mesh makes it difficult for materials with poor flowability to pass through.

[0004] In view of the above problems, it is necessary to improve the existing magnetic conductive module and magnetic separator. Utility Model Content

[0005] The purpose of this invention is to provide a protective magnetic conductive module and magnetic separator to address the above problems, thereby solving the problem in the prior art where the impact and friction between magnetic conductive meshes generates debris that affects the purity of the material.

[0006] To achieve the above objectives, this utility model discloses a protective magnetic conductive module. This module includes a vertically arranged central shaft and multiple layers of magnetic conductive mesh. The central shaft passes through the central hole of each magnetic conductive mesh, which is mounted on the central shaft. The multiple layers of magnetic conductive mesh are vertically spaced apart. An inner protective washer and an outer protective washer are provided between adjacent magnetic conductive meshes. The inner protective washer is fitted onto the central shaft and serves as a spacer for protection between adjacent magnetic conductive meshes near the central hole. The outer protective washer includes an outer cylinder and an inner baffle connected to the inner wall of the outer cylinder. The outer cylinder wraps around the outer edge of at least one of the adjacent magnetic conductive meshes, and the inner baffle is located between the adjacent magnetic conductive meshes. With this structure, the inner and outer protective washers are located at the middle and outer edges of the magnetic conductive meshes, respectively. This not only solves the problem of debris generated by collisions and friction between adjacent magnetic conductive meshes affecting material purity but also creates gaps between the magnetic conductive meshes, improving material permeability. The inner protective washer is fixed in its working position by being fitted onto the central shaft, and the outer protective washer is fixed in its working position by being wrapped around the outer edge of the magnetic mesh by the outer cylinder. The inner and outer protective washers located between the same pair of magnetic meshes cooperate with each other to form comprehensive protection and isolation in the middle and outer edge of the magnetic mesh.

[0007] Furthermore, the inner protective washer is a flat washer with a central hole. The flat washer structure is suitable for use when friction between the inner hole of the magnetic mesh and the central shaft is negligible, and using a flat washer reduces manufacturing costs.

[0008] Furthermore, the inner protective gasket includes an inner cylinder and an outer baffle connected to the outer wall of the inner cylinder. The inner cylinder extends into the inner hole of at least one of two adjacent magnetic mesh sheets, and the outer baffle is located between the two adjacent magnetic mesh sheets. With the above structure, the inner cylinder forms a protective barrier between the inner hole of the magnetic mesh sheet and the central axis, and the outer baffle forms a protective barrier between the two adjacent magnetic mesh sheets, providing comprehensive protection.

[0009] Furthermore, the inner baffle of the outer protective gasket is located at the upper part, lower part, or axial middle of the outer cylinder. The portion of the outer cylinder above the inner baffle wraps around the outer edge of the upper magnetic mesh of two adjacent magnetic meshes, and the portion of the outer cylinder below the inner baffle wraps around the outer edge of the lower magnetic mesh of two adjacent magnetic meshes. With this structure, one inner baffle divides the outer cylinder into upper and lower parts. These two parts of the outer cylinder are respectively wrapped around the magnetic meshes located above and below the inner baffle. While spacing them between two magnetic meshes, this design makes the connection between the upper and lower magnetic meshes tighter, thereby forming a unified whole from multiple layers of magnetic meshes and enhancing the structural stability of the protective magnetic module.

[0010] Furthermore, the inner baffle is annular. The annular inner baffle, combined with the outer cylinder, makes the outer protective gasket structure more robust.

[0011] Furthermore, the inner protective gasket and / or outer protective gasket are made of polymer materials. Polymer materials have strong protective properties, which helps to improve the protective effect on the magnetic mesh.

[0012] Furthermore, the inner protective gasket and / or outer protective gasket is made of rubber, nylon, or polyurethane. Rubber, nylon, and polyurethane are preferred materials for the outer protective gasket because they are relatively soft, wear-resistant, provide good protection, and have a long service life.

[0013] Furthermore, the surface of the magnetic mesh is provided with a wear-resistant protective layer. This wear-resistant protective layer reduces wear on the magnetic mesh from materials and prevents debris from the mesh from entering the material. Combined with inner and outer protective gaskets, it prevents collisions and friction between the magnetic meshes, further protecting the wear-resistant protective layer from damage. This comprehensively prevents contamination of the material caused by wear during the operation of the magnetic separator, thus improving the iron removal and purification effect of the magnetic separator.

[0014] This utility model also discloses a magnetic separator, which has a magnetic separation channel in which the aforementioned protective magnetic guiding module is installed. The magnetic separator employs the aforementioned protective magnetic guiding module, solving the problem of debris generated by impact and friction between the magnetic mesh sheets. This not only improves the material purification effect but also enhances the material's permeability.

[0015] Furthermore, the magnetic separation channel is equipped with a wear-resistant protective layer or an isolation layer of the same material as the magnetic separation material. By providing a wear-resistant protective layer or an isolation layer of the same material as the magnetic separation material in the magnetic separation channel, material contamination caused by wear of the magnetic separation channel during operation can be prevented. Combined with the protective magnetic guiding module, the material purification effect is comprehensively improved.

[0016] In summary, the beneficial effects of this utility model are as follows: By uniquely designing inner and outer protective washers between the magnetic mesh sheets, this utility model not only solves the problem of debris generated by collisions and friction between adjacent magnetic mesh sheets affecting material purity, but also creates gaps between the magnetic mesh sheets, which improves material throughput. Combined with improvements to the magnetic separator, this enhances the iron removal and purification effect of the magnetic separator. Attached Figure Description

[0027] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0028] Firstly, this utility model provides a protective magnetic conductive module 200.

[0029] Reference Figures 1 to 4In some embodiments of the present invention, the protective magnetic conductive module 200 includes a vertically arranged central shaft 1 and multiple layers of magnetic conductive mesh 2. The central shaft 1 passes through the central hole of the magnetic conductive mesh 2, and the magnetic conductive mesh 2 is mounted on the central shaft 1. The multiple layers of magnetic conductive mesh are arranged vertically at intervals. An inner protective washer 3 and an outer protective washer 4 are provided between adjacent magnetic conductive mesh 2. The inner protective washer 3 is fitted onto the central shaft 1, and its working position is fixed by fitting onto the central shaft 1. The inner protective washer 3 is used for spaced protection of the area near the central hole of two adjacent magnetic conductive mesh 2. The outer protective washer 4 is located at the outer edge of two adjacent magnetic conductive mesh 2 and is used for protection at the outer edge of two adjacent magnetic conductive mesh 2. Through the above improvements, the inner protective washer 3 and the outer protective washer 4 are located at the middle and outer edge of the magnetic conductive mesh 2, respectively. This not only solves the problem of debris generated by collision and friction between adjacent magnetic conductive mesh 2 affecting the purity of the material, but also creates gaps between the magnetic conductive mesh 2, which is beneficial to improving the material's permeability.

[0030] Reference Figure 5 , Figure 6 In some embodiments of the present invention, the outer protective washer 4 includes an outer cylinder 41 and an inner baffle 42 connected to the inner wall of the outer cylinder 41, combined with Figure 4 , Figure 6 The outer cylinder 41 wraps around the outer edge of at least one of the two adjacent magnetic mesh sheets 2, and the inner baffle 42 is located between the two adjacent magnetic mesh sheets 2. The outer protective washer 4 is fixed in its working position by the outer cylinder 41 wrapping around the outer edge of the magnetic mesh sheet 2. The inner protective washer 3 located between the same pair of magnetic mesh sheets 2 cooperates with the outer protective washer 4 to form comprehensive protection and isolation at the middle and outer edge of the magnetic mesh sheet 2. In the illustrated embodiment, the inner baffle 42 of the outer protective washer 4 is located at the axial middle part of the outer cylinder 41. The part of the outer cylinder 41 above the inner baffle 42 wraps around the outer edge of the upper magnetic mesh sheet 2 among the two adjacent magnetic mesh sheets 2, and the part of the outer cylinder 41 below the inner baffle 42 wraps around the outer edge of the lower magnetic mesh sheet 2 among the two adjacent magnetic mesh sheets 2. The inner baffle 42 divides the outer cylinder 41 into upper and lower parts. These two parts of the outer cylinder 41 are respectively wrapped around the magnetic mesh 2 located above and below the inner baffle 42. While separating the two magnetic meshes 2, this design makes the upper and lower magnetic meshes 2 more tightly joined, thereby forming a whole from the multiple layers of magnetic meshes 2 and enhancing the structural stability of the protective magnetic module 200. In the illustrated embodiment, the inner baffle 42 is annular. The annular inner baffle 42 combined with the outer cylinder 41 makes the structure of the outer protective gasket 4 more robust. Of course, in addition to the illustrated embodiment, the inner baffle 42 of the outer protective gasket 4 can also be located at the upper or lower part of the outer cylinder 41, and these structures are also within the protection scope of this utility model.

[0031] Reference Figure 7 , Figure 8In some embodiments of the present invention, the inner protective washer 3 includes an inner cylinder 31 and an outer baffle 32 connected to the outer wall of the inner cylinder 31. The inner cylinder 31 extends into the inner hole of at least one of two adjacent magnetic mesh sheets 2, and the outer baffle 32 is located between the two adjacent magnetic mesh sheets 2. With the above structure, the inner cylinder 31 forms protection between the inner hole of the magnetic mesh sheet 2 and the central shaft 1, and the outer baffle 32 forms protection between the two adjacent magnetic mesh sheets 2, providing more comprehensive protection. In other embodiments of the present invention, the inner protective washer 3 is a flat washer with a central hole. The flat washer structure of the inner protective washer 3 is suitable for use when the friction between the inner hole of the magnetic mesh sheet 2 and the central shaft 1 is negligible, and the use of a flat washer can reduce manufacturing costs.

[0032] The inner protective gasket 3 and / or the outer protective gasket 4 are preferably made of polymer materials. Polymer materials have strong protective properties, which helps to improve the protective effect on the magnetic mesh 2. In particular, the inner protective gasket 3 and / or the outer protective gasket 4 are preferably made of rubber, nylon, or polyurethane. Rubber, nylon, and polyurethane are preferred materials for the outer protective gasket because they are relatively soft, wear-resistant, have good protective effect, and long service life.

[0033] In some embodiments of the present invention, the protective magnetic conductive module 200 is further improved: the surface of the magnetic conductive mesh 2 is provided with a wear-resistant protective layer. The wear-resistant protective layer can reduce the wear of the material on the magnetic conductive mesh 2 and prevent the debris of the magnetic conductive mesh 2 from entering the material. Combined with the inner protective gasket 3 and the outer protective gasket 4, collision and friction between the magnetic conductive mesh 2 are prevented, further protecting the wear-resistant protective layer from damage. This comprehensively prevents the contamination of the material caused by its own wear during the operation of the magnetic separator, and improves the iron removal and purification effect of the magnetic separator.

[0034] Secondly, the present invention also provides a magnetic separator.

[0035] Reference Figure 9 In some embodiments of the present invention, the aforementioned protective magnetic guiding module 200 is installed within the magnetic separation channel 100. The magnetic separator employs the aforementioned protective magnetic guiding module 200, which solves the problem of debris generated by impact and friction between the magnetic mesh sheets. This not only improves the material purification effect but also enhances the material throughput.

[0036] In some embodiments of the present invention, a wear-resistant protective layer or an isolation layer of the same material as the magnetic separation material is provided inside the magnetic separation channel 100. By providing a wear-resistant protective layer or an isolation layer of the same material as the magnetic separation material inside the magnetic separation channel 100, material contamination caused by wear of the magnetic separation channel 100 during the operation of the magnetic separator can be prevented. Combined with the protective magnetic conductive module 200, the material purification effect is comprehensively improved.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
