Description

Technical Field

[0001] This utility model mainly relates to the field of iron separator technology, specifically to a magnetic separator with a special magnetic field. Background Technology

[0002] A grid magnetic separator, also known as a grid-type magnetic separator or magnetic grid, is a device that uses a magnetic grid as the main iron removal unit. With the addition of auxiliary facilities, it can be easily installed on the production line to remove iron impurities from materials. The grid magnetic separator works by using magnetic force. When materials flow through the magnetic grid, iron impurities are magnetically attracted to the magnetic grid, thereby removing the iron impurities.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Current grid iron separators come in various forms, most of which place spaced magnetic bars on a support. There are no restrictions on the number or arrangement of the magnetic bars. Iron removal is carried out by the natural flow of fluid. However, this method has limited magnetic strength, and the magnetic material adsorbed after demagnetization is difficult to clean.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] This invention provides a magnetic separator with a special magnetic field to solve the technical problems existing in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows: a magnetic separator with a special magnetic field, comprising symmetrically arranged fixed plates, with a receiving tube between the fixed plates, and multiple magnets spaced apart inside the receiving tube. The magnets are connected by separators, and the magnets are arranged in an odd number. The magnetic fields of the parallel magnets inside the receiving tubes are arranged in opposite directions. This device is installed in the material channel where iron removal is required. When the material passes through the spaced-apart receiving tubes, the magnetic material is attracted to the outer wall of the receiving tube under the influence of the magnets inside. After working for a period of time, the device is disassembled, the internal magnets are pulled out, and the outer wall of the receiving tube loses its magnetic force, facilitating the cleaning of external magnetic materials. Because this device uses an odd number of magnets and the parallel magnets have opposite magnetic field directions, the magnetic field they form has a stronger adsorption effect and a higher surface magnetic induction intensity.

[0010] Furthermore, the number of magnets is set to seven.

[0011] Furthermore, the separator is made of a high magnetic permeability material.

[0012] Furthermore, the separator is made of a material with high saturation magnetization.

[0013] Furthermore, the high magnetic permeability material is at least one of soft iron, permalloy, and amorphous alloy.

[0014] Furthermore, the material with high saturation magnetization is at least one of pure iron, silicon steel, beryllium iron alloy, cobalt ferrite, and iron-nickel-cobalt alloy.

[0015] Furthermore, one end of the fixing plate on one side is provided with a sealing cap, and the bottom of the receiving tube of the fixing plate on the other side is provided with a limiting mechanism. The limiting mechanism includes a fixing block, and a limiting groove is opened in the fixing block. The top of the limiting groove is matched and connected to a snap-fit ​​slider. The bottom of the snap-fit ​​slider is connected to the bottom of the limiting groove by a spring. A toggle block is provided on both sides of the top of the snap-fit ​​slider.

[0016] Furthermore, the magnet is neodymium iron boron or aluminum nickel cobalt.

[0017] Furthermore, the receiving tube is made of at least one of stainless steel, aluminum, plastic, and ceramic materials.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0020] This utility model is reasonably designed, using multiple parallel receiving tubes to load magnets. The odd number of magnets and the special magnetic arrangement result in receiving tubes with a large surface magnetic field to adsorb materials, achieving good adsorption and iron removal effects. The limiting mechanism facilitates the quick disassembly and installation of the internal magnets.

[0028] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0029] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "page", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Furthermore, 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. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," "fixed," "provided with," and "located in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0032] See attached document Figures 1-4A magnetic separator with a special magnetic field includes symmetrically arranged fixed plates 1, with receiving tubes 2 between the fixed plates 1. Multiple magnets 3 are spaced apart within the receiving tubes 2 and connected by separators 4. The magnets 3 are arranged in an odd number, and the magnetic fields of the parallel magnets 3 within the receiving tubes 2 are arranged in opposite directions. This device is installed in a material channel requiring iron removal. When material passes through the spaced-apart receiving tubes 2, the magnetic material is attracted to the outer wall of the receiving tubes 2 under the influence of the magnets 3. After a period of operation, the device is disassembled, and the internal magnets 3 are removed. The outer wall of the receiving tubes 2 loses its magnetic force, facilitating the cleaning of external magnetic materials. Because this device uses an odd number of magnets 3, and the parallel magnets 3 have opposite magnetic field directions, the resulting magnetic field has a stronger adsorption effect and a higher surface magnetic induction intensity.

[0033] The combination of magnets 3 and receiving tubes 2 arranged in this manner can generate a strong radial magnetic field distribution, strengthen the magnetic flux path, reduce magnetic resistance, and make the magnetic field more concentrated and powerful, effectively adsorbing iron impurities in materials.

[0034] Please refer to Figure 4 The number of magnets 3 is seven. It should be noted that the number of magnets 3 in this application can be designed differently according to the adsorption material. The minimum number is three. This embodiment illustrates a commonly used combination of magnets 3 and does not limit the number of magnets 3.

[0035] The separator 4 is made of a high magnetic permeability material to ensure the magnetic field adsorption effect.

[0036] The separator 4 is made of a material with high saturation magnetization to ensure the magnetic field adsorption effect.

[0037] The high magnetic permeability material is at least one of soft iron, permalloy, and amorphous alloy.

[0038] The material with high saturation magnetization is at least one of pure iron, silicon steel, beryllium iron alloy, cobalt ferrite, and iron-nickel-cobalt alloy.

[0039] One end of the fixing plate 1 on one side is provided with a sealing cap, and the bottom of the receiving tube 2 of the fixing plate 1 on the other side is provided with a limiting mechanism 5. The limiting mechanism 5 includes a fixing block 51, and a limiting groove 52 is opened in the fixing block 51. The top of the limiting groove 52 is matched and connected to a snap-fit ​​slider 53. The bottom of the snap-fit ​​slider 53 is connected to the bottom of the limiting groove 52 by a spring 54. Actuating blocks 55 are provided on both sides of the top of the snap-fit ​​slider 53. Please refer to [reference needed]. Figure 2To facilitate the placement of magnet 3 into the receiving tube 2, a limiting mechanism 5 is set up. First, magnet 3 and separator 4 are pasted into a column. Then, magnet 3 is placed into the receiving tube 2. Before placement, the actuating block 55 is pressed down. After magnet 3 is placed in, the actuating block 55 is released. Under the action of spring 54, the slider 53 is pushed up, thereby limiting magnet 3 and preventing magnet 3 from falling outward during operation.

[0040] The magnet 3 is neodymium iron boron or aluminum nickel cobalt. This embodiment only exemplifies commonly used magnet 3 materials. It should be noted that magnet 3 can also be made of other permanent magnet materials or non-permanent magnet materials, as long as it has a magnetic attraction effect. This authorization does not specifically limit the actual material of magnet 3.

[0041] The receiving tube 2 is made of at least one of stainless steel, aluminum, plastic and ceramic materials. In this embodiment, a material with less magnetic influence is used as the raw material for making the receiving tube 2, so the influence on the magnitude of the magnetic force is small.

[0042] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
