Description

Technical Field

[0001] The utility model relates to an iron remover, in particular to an iron remover with a ferromagnetic material adsorption function, belonging to the technical field of iron removal equipment. Background Art

[0002] Usually, an iron remover is an electromagnetic or permanent magnetic device that removes iron from the target or carries magnetic materials that can be screened out by the iron remover. The basic principle is that the ferromagnetic material is affected by the magnetic force in the magnetic field, causing the magnetic material to move and separate from the material to achieve the sorting purpose. It can purify materials, improve material grade or protect equipment. It is mainly used in various industrial fields, such as mining, cement, chemical packaging and printing, and food processing.

[0003] When removing ferromagnetic impurities from some dry powder, flake, granular and other materials, various types of magnetic rod iron removers or electromagnetic iron removers are usually used. The magnetic rod iron remover is to set up multiple magnetic rods, put the material in from the top, and use multiple magnetic rods to adsorb the ferromagnetic substances in the material to remove iron. However, the quality of iron removal is proportional to the density of the magnetic rods. If the iron removal effect is improved, multiple sets of magnetic rods need to be set up, the cost will increase, and the iron filings will be inconvenient to remove. The electromagnetic iron remover generates a magnetic field by energizing the coil. The magnetic field forms a high-density magnetic field in the magnetic cavity through the magnetic circuit. The magnetic net in the magnetic cavity is magnetized to generate a strong magnetic field. When the material is put into the magnetic cavity, it will be adsorbed on the magnetic net for iron removal. However, when the material enters the magnetic cavity, the magnetic material doped in the material near the inner wall of the magnetic net will be adsorbed, but due to the small magnetic field in the center of the magnetic cavity, some ferromagnetic substances may not be completely adsorbed, and when there are more materials falling into the magnetic cavity, it may also lead to poor iron removal effect, affecting the subsequent use of the material.

[0004] Therefore, there is an urgent need to improve the iron remover with the function of adsorbing ferromagnetic materials to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] like Figure 1-Figure 3As shown, the iron remover with ferromagnetic material adsorption function provided in this embodiment includes an electromagnetic box 1, a magnetic conductive net 11 is provided in the middle of the electromagnetic box 1, wherein the magnetic conductive net 11 can be made of thin iron sheets or nickel sheets, rather than a grid, to prevent materials from entering the mesh and being difficult to clean. A coil 12 is provided inside the electromagnetic box 1, and the coil 12 is wound around the outside of the magnetic conductive net 11. The upper end of the magnetic conductive net 11 is connected to a feed hopper 13, and the lower end of the magnetic conductive net 11 is connected to a discharge hopper 14. When the coil 12 is energized A magnetic field is generated, and the magnetic field forms a high-density magnetic field in the magnetic cavity through the magnetic conductive circuit. At this time, the magnetic conductive net 11 is magnetized to generate a strong magnetic field. Then the material in the feed hopper 13 falls and passes through the magnetic conductive net 11 into the discharge hopper 14. The magnetic impurities in the material are adsorbed on the magnetic conductive net 11. This technology is a prior art and will not be described in detail here. It also includes a rotating member 2, a guide plate 3, an intermittent unloading plate 4 and a driving member 5. The driving member 5 is used to drive the rotating member 2 to rotate. The driving member 5 can be an electric The rotating member 2 is located inside the magnetic conductive net 11 and coincides with the axis of the magnetic conductive net 11. The rotating member 2 is connected to the guide plate 3, and the diameter of the guide plate 3 gradually increases from top to bottom. When the material in the feed hopper 13 falls, it will be guided to the vicinity of the circumferential inner wall of the magnetic conductive net 11 through the guide plate 3, so that the material is closer to the part with a stronger magnetic field near the magnetic conductive net 11, avoiding the poor demagnetization effect caused by the weak magnetic field in the center of the magnetic conductive net 11. At the same time, the intermittent unloading plate 4 and the rotating member 2 The intermittent unloading plate 4 and the lower end of the feed hopper 13 are connected, and the upper end surface of the intermittent unloading plate 4 is in contact with the lower end surface of the feed hopper 13. A plurality of leakage holes 41 are provided at the lower ends of the intermittent unloading plate 4 and the feed hopper 13. When the rotating part 2 drives the leakage holes 41 on the intermittent unloading plate 4 to coincide with the leakage holes 41 below the feed hopper 13, the material in the feed hopper 13 falls. When the two are misaligned with each other, the discharge of material in the feed hopper 13 stops, and this cycle is repeated to realize intermittent unloading, thereby avoiding uneven demagnetization caused by too much material falling in at one time.

[0022] Further, such as Figure 3 As shown, it also includes a sweeping plate 6, and the number of sweeping plates 6 is multiple, and the multiple sweeping plates 6 are all connected to the rotating member 2. When the rotating member 2 rotates, it will drive the sweeping plate 6 to rotate synchronously, sweep the materials that fall into the magnetic conductive net 11, and disperse the materials, thereby expanding the contact area with the magnetic conductive net 11 to further improve the demagnetization effect.

[0023] Further, if Figure 3 As shown, one end of the rotating member 2 extends to the interior of the feed hopper 13 and is rotatably connected to the feed hopper 13. A toggle rod 21 is provided on the outer wall of one end of the rotating member 2 located in the feed hopper 13. Since the powdered material has poor fluidity, it flows slowly in the feed hopper 13 and is easily accumulated near the outlet. While the toggle rod 21 can rotate synchronously with the rotating member 2, the powdered material in the feed hopper 13 is continuously stirred to prevent the powdered material from being blocked in the feed hopper 13.

[0024] Furthermore, Figure 3 As shown, a protective cover 7 is connected to the lower end of the rotating member 2, and the protective cover 7 is located above the driving member 5 to form a protection above the driving member 5 to prevent materials from falling directly onto the driving member 5, and the shape and structure of the protective cover 7 can be similar to that of the material guide seat, and can be a cone-shaped structure to prevent materials from accumulating and remaining on the protective cover 7.

[0025] like Figure 3 As shown, a bracket 8 is provided on the inner wall of the magnetic conductive net 11, and the other end of the bracket 8 is connected to the driving member 5 for supporting the driving member 5 to make the driving member 5 more stable.

[0026] like Figure 3 As shown, the discharge hopper 14 is provided with a first discharge channel 9 and a second discharge channel 91, and the interior of the discharge hopper 14 is provided with a first baffle 92 and a second baffle 93, the first baffle 92 is parallel to the extension direction of the first discharge channel 9, and the second baffle 93 is parallel to the extension direction of the second discharge channel 91. When the material is discharged, the second baffle 93 is connected to the second channel, and the first baffle 92 is taken out. At this time, the material entering the discharge hopper 14 will be discharged through the first channel, and when the magnetic impurities on the magnetic conductive net 11 need to be discharged, the first channel is blocked by the first baffle 92, and the second baffle 93 is taken out, and at the same time, the coil 12 is powered off to make the magnetic conductive net 11 lose its magnetic field, and the magnetic impurities lose their suction and are discharged through the second channel.

[0027] Further, such as Figure 3 As shown, the rotating member 2, the guide plate 3 and the sweeping plate 6 are all made of non-magnetic materials, such as ferrite, ceramic, glass, etc. These materials will not be affected by the magnetic field and will not interfere with the adsorption of magnetic impurities by the magnetic conductive net 11.

[0028] like Figure 1-Figure 3 As shown, the principle of the iron remover with ferromagnetic material adsorption function provided in this embodiment is as follows: the rotating member 2 is driven to rotate by the driving member 5. When the rotating member 2 drives the leakage hole 41 on the intermittent unloading plate 4 to coincide with the leakage hole 41 under the feed hopper 13, the material in the feed hopper 13 falls. When the two are misaligned with each other, the material is stopped. In this way, intermittent unloading is realized reciprocatingly. At the same time, the material falling into the magnetic conductive net 11 falls on the material guide seat and is guided to the vicinity of the inner wall of the magnetic conductive net 11, so that the fallen material is as close as possible to the position with a larger magnetic field near the magnetic conductive net 11, thereby improving the adsorption effect of the magnetic material in the material. At the same time, the sweeping plate 6 will continuously sweep the material as it follows the rotation of the rotating member 2, so that the material can contact the magnetic conductive net 11 more evenly, thereby improving the iron removal effect.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction.
