Description

Technical Field

[0001] This utility model belongs to the field of microsilica iron removal technology, and specifically relates to a microsilica iron removal device. Background Technology

[0002] Microsilica is a byproduct of large-scale industrial smelting. It is produced in electric arc furnaces during the smelting of ferrosilicon and industrial silicon (metallic silicon). A large amount of highly volatile SiO2 and Si gases are generated. After the gases are released, they are rapidly oxidized, condensed and precipitated with air. The main component is silicon dioxide. Impurities include sodium oxide, calcium oxide, magnesium oxide, iron oxide and aluminum oxide. The silicon content is generally 80-92%. Microsilica contains iron oxide impurities, which need to be removed using an iron removal device.

[0003] When removing iron impurities by magnetic attraction, the electromagnetic coil and magnetic core are usually installed inside the device. When it is necessary to replace or repair the electromagnetic coil and magnetic core, the internal space of the device is small, making replacement inconvenient. Therefore, a technical measure is proposed to solve the problem that the electromagnetic coil and magnetic core are usually installed inside the device in the existing technology, and the convenience of replacing and repairing the electromagnetic coil and magnetic core needs to be improved. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a micro-silica iron removal device, which aims to solve the problem that the electromagnetic coil and magnetic core are usually installed inside the device in the existing technology, and the convenience of replacing and repairing the electromagnetic coil and magnetic core needs to be improved.

[0006] Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a microsilica powder iron removal device, comprising a housing and a box. The housing is hollow in the middle, and a sliding groove is formed in the middle of the upper surface of the housing. A displacement component is installed on the upper surface of the box, and a slider is slidably connected to the sliding groove. The slider is fixedly connected to the displacement component. An electromagnetic coil is installed inside the box, and a magnetic core is nested inside the electromagnetic coil. The magnetic core is fixedly installed inside the box. Thanks to the displacement component, the box and its cover can be easily moved out of the housing, thus providing a larger working space for easy inspection and replacement of the electromagnetic coil and magnetic core, improving practicality and convenience.

[0008] Furthermore, a controller is installed on the upper side of the enclosure.

[0009] Furthermore, two sets of symmetrically distributed mounting plates are installed in the hollow part of the box. A first motor is installed on the side of one set of mounting plates. The first motor is connected to a drive roller. A conveyor belt is sleeved on the outside of the drive roller. A driven roller is sleeved on the other end of the conveyor belt.

[0010] Furthermore, a cylinder is passed through the middle of the upper part of the slider, and a lifting plate is connected to the lower end of the cylinder. The side of the lifting plate is fixedly connected to the box body, and a box cover is threadedly installed on the upper part of the box body. Thanks to the setting of the cylinder and the lifting plate, it is convenient to move the box body closer to the microsilica powder, thereby improving the absorption effect of iron impurities.

[0011] Furthermore, the box is located in the middle of the interior of the box.

[0012] Furthermore, the displacement assembly includes two sets of vertical plates, which are fixedly and symmetrically installed on the upper surface of the housing, with the vertical plates close to the slide groove.

[0013] Furthermore, a second motor is installed at the middle position of the side of one of the vertical plates. The second motor is connected to a screw, and the screw is threaded to a ring. A connecting rod is installed at the middle position of the side of the ring. A connecting plate is installed at the end of the connecting rod away from the ring. The lower end of the connecting plate is fixedly connected to the upper surface of the slider.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, through the design of a cylinder and a lifting plate, facilitates bringing the box closer to the microsilica powder, thereby improving the absorption effect of iron impurities. The cylinder's activation causes the lifting plate to move downwards, which in turn causes the box to move downwards.

[0017] The combination of slider and groove provides a limit to the movement of the box, preventing deflection.

[0018] By setting up the shifting component, it is easy to move the box body and box cover out of the box, thereby providing a larger working space, which facilitates the inspection and replacement of electromagnetic coils and magnetic cores, improving practicality and convenience. The second motor is started to drive the connecting plate to move. The movement of the connecting plate causes the slider to slide along the slide groove (moving in the direction away from the driven roller), and then the box body and box cover are moved out of the box.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This specific embodiment is a microsilica powder iron removal device, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 , Figure 3As shown, the device includes a box body 1 and a housing 13. The box body 1 is hollow in the middle. A groove 9 is formed in the middle of the upper surface of the box body 1. A displacement component 2 is installed on the upper surface of the box body 1. A slider 11 is slidably connected to the groove 9. The slider 11 is fixedly connected to the displacement component 2. An electromagnetic coil 15 is installed inside the housing 13. A magnetic core 16 is sleeved inside the electromagnetic coil 15 and fixedly installed inside the housing 13. A controller 5 is installed on the upper side of the box body 1. Two sets of symmetrically distributed mounting plates 3 are installed in the hollow part of the box body 1. A first motor 8 is installed on the side of one set of mounting plates 3. The first motor 8 is connected to a drive roller 6. A conveyor belt 7 is sleeved on the outside of the drive roller 6. A driven roller 4 is sleeved on the other end of the conveyor belt 7. A cylinder 10 passes through the middle of the upper part of the slider 11. A lifting plate 12 is connected to the lower end of the cylinder 10. The side of the lifting plate 12 is fixedly connected to the housing 13. A cover 14 is threadedly installed on the upper part of the housing 13. The housing 13 is located in the middle of the interior of the box body 1. When removing iron from the silica powder, the controller 5 starts the cylinder 10 to move the lifting plate 12 downward. The downward movement of the lifting plate 12 moves the box body 13 and the box cover 14 downward to approach the conveyor belt 7. Then, the electromagnetic coil 15 is energized (when the current passes through, a magnetic field is generated, and the magnitude of the magnetic field is positively correlated with the magnitude of the current and the number of coil turns). The electromagnetic coil 15 then magnetizes the box body 13 (the box body 13 is made of stainless steel, and the magnetic core 16 can enhance the magnetic field). Then, the first motor 8 is started to drive the active roller 6 to rotate. The rotation of the active roller 6 drives the conveyor belt 7 to rotate, and the rotation of the conveyor belt 7 drives the driven roller 4 to rotate. Then, the silica powder is put into the conveyor belt 7. When the silica powder passes through the box body 13, the box body 13 absorbs the iron powder (iron oxide impurities). When it is necessary to replace or repair the magnetic core 16 and the electromagnetic coil 15, the shifting component 2 drives the cylinder 10, the slider 11, the lifting plate 12, the box body 13, and the box cover 14 to move horizontally. Then, the box body 13 and the box cover 14 are moved out of the box body 1.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the shifting assembly 2 includes two sets of vertical plates 201. These two sets of vertical plates 201 are fixedly and symmetrically installed on the upper surface of the housing 1, with the vertical plates 201 close to the slide groove 9. A second motor 202 is installed at the middle position of the side of one set of vertical plates 201. The second motor 202 is connected to a screw 203, which is threadedly connected to a ring 206. A connecting rod 204 is installed at the middle position of the side of the ring 206. A connecting plate 205 is installed at the end of the connecting rod 204 away from the ring 206. The lower end of the connecting plate 205 is connected to the slide groove 9. The upper surface of block 11 is fixedly connected. The second motor 202 is started to drive the screw 203 to rotate. The rotation of the screw 203 drives the ring 206 to move along it. The movement of the ring 206 drives the connecting rod 204 to move. The movement of the connecting rod 204 drives the connecting plate 205 to move. The movement of the connecting plate 205 drives the slider 11 to slide along the slide groove 9 (moving in a direction away from the driven roller 4). Then the box body 13 and the box cover 14 are removed from the inside of the box body 1. Then the box cover 14 is opened to inspect and replace the electromagnetic coil 15 and the magnetic core 16.

[0028] Working principle: In actual iron removal from microsilica powder, the controller 5 starts the cylinder 10 to move the lifting plate 12 downwards. The downward movement of the lifting plate 12 moves the box body 13 and the box cover 14 downwards towards the conveyor belt 7. Then, the electromagnetic coil 15 is energized (a magnetic field is generated when current passes through it, and the strength of the magnetic field is positively correlated with the current and the number of coil turns). The electromagnetic coil 15 then magnetizes the box body 13 (the box body 13 is made of stainless steel, and the magnetic core 16 can enhance the magnetic field). Then, the first motor 8 is started to drive the drive roller 6 to rotate. The rotation of the drive roller 6 drives the conveyor belt 7 to rotate, and the rotation of the conveyor belt 7 drives the driven roller 4 to rotate. Microsilica powder is placed on conveyor belt 7. When the microsilica powder passes through box 13, box 13 absorbs iron powder (iron oxide impurities). When it is necessary to replace or repair the magnetic core 16 and electromagnetic coil 15, the shifting component 2 drives the cylinder 10, slider 11, lifting plate 12, box 13 and box cover 14 to move horizontally. Then the box 13 and box cover 14 are moved out from the box 1. The setting of cylinder 10 and lifting plate 12 makes it easy to move box 13 closer to microsilica powder, thereby improving the absorption effect of iron impurities. The slider 11 and the slide 9 work together to limit the movement of box 13 and prevent deflection.

[0029] The specific working method of the shifting component 2 is as follows: the second motor 202 is started to drive the screw 203 to rotate. The rotation of the screw 203 drives the ring 206 to move along it. The movement of the ring 206 drives the connecting rod 204 to move. The movement of the connecting rod 204 drives the connecting plate 205 to move. The movement of the connecting plate 205 drives the slider 11 to slide along the slide groove 9 (moving away from the driven roller 4). Then the box body 13 and the box cover 14 are moved out of the box body 1. Then the box cover 14 is opened to inspect and replace the electromagnetic coil 15 and the magnetic core 16. The shifting component 2 is designed to facilitate the movement of the box body 13 and the box cover 14 out of the box body 1, thereby providing a larger working space and facilitating the inspection and replacement of the electromagnetic coil 15 and the magnetic core 16, thus improving practicality and convenience.
