Description

Technical Field

[0001] The utility model relates to the field of industrial equipment, in particular to a device for removing magnetic impurities from sintered ash. Background Art

[0002] Sinter ash is a waste product generated during steel production, primarily from the electrostatic precipitator (ESP) of steelmaking sintering machines. Sinter ash contains elements such as iron, potassium, sodium, and zinc, and possesses considerable utility. Sinter ash can be processed to extract these valuable elements.

[0003] However, sintered ash contains a large amount of magnetic impurities, which cause great wear to equipment during the production process, thus affecting production efficiency. In real scenarios, conventional impurity removal devices can only remove magnetic impurities on the surface of sintered ash, and sintered ash easily forms lumps, making it difficult to remove the magnetic impurities wrapped inside the lumps. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a device for removing magnetic impurities of sintered ash that can not only remove the surface but also remove the internal sintered ash when it is agglomerated.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a sintered ash magnetic impurity removal device, comprising a first impurity removal mechanism arranged above the conveyor belt and a second impurity removal mechanism arranged below the conveyor belt;

[0006] The first impurity removal mechanism includes a first magnet, which is arranged above the end of the conveyor belt, and a gap is left between the first magnet and the conveyor belt for the sintered ash to pass through;

[0007] The second impurity removal mechanism includes a chute arranged at the bottom of the conveyor belt discharge port and inclined downward, a scattering component is set on the top of the chute, a second magnet is set at the lower end of the chute, and a gap is left between the second magnet and the bottom of the chute for the sintered ash to pass through.

[0008] The beneficial effects of the above technical solution are: the first impurity removal mechanism above the conveyor belt can remove magnetic impurities on the surface of the sintered ash; the second impurity removal mechanism below the conveyor belt includes a scattering component, which can scatter all the sintered ash conveyed by the conveyor belt, and then completely expose the magnetic impurities inside the agglomerated sintered ash, including the agglomerated sintered ash, and then pass through the impurity removal of the second magnet to ensure that the magnetic impurities in the sintered ash are completely removed.

[0009] Furthermore, the first magnet and the second magnet are both cylindrical structures and are both rotatable.

[0010] Beneficial effects: On the one hand, rotation can extend the adsorption area of ​​the magnet, increase the amount of magnetic impurities attached to the magnet, and at the same time avoid excessive attachment of magnetic impurities affecting the passage of sintered ash; on the other hand, as the magnetic impurities adhere, the adsorption force of the magnetic surface separated by the magnetic impurities decreases. Rotation can keep the adsorption force of the magnet on the magnetic impurities at a relatively high level, ensuring the removal effect of magnetic impurities.

[0011] Furthermore, the conveyor belt includes a conveyor belt body and frames on both sides of the conveyor belt body. Supports are fixedly provided on the frames on the front and rear sides of the conveyor belt end. A first rotating shaft is rotatably set between the front and rear supports. The first magnet is fixedly mounted on the first rotating shaft, and the end of the first rotating shaft is connected to the first motor. A second rotating shaft is rotatably set between the trough walls at the lower end of the chute, the second magnet is fixedly mounted on the second rotating shaft, and the end of the second rotating shaft is connected to the second motor.

[0012] Beneficial effect: the first motor drives the first magnet to rotate; the second motor drives the second magnet to rotate.

[0013] Furthermore, a slot which is right-open and transparent up and down is provided at the lower end of the bottom of the chute, and the second magnet is rotatably arranged in the slot.

[0014] Beneficial effect: The sintered ash flows directly onto the second magnet along the chute, thereby increasing the contact area between the sintered ash and the second magnet and enhancing the impurity removal effect of the second magnet.

[0015] Furthermore, the breaking up assembly includes a wolf tooth roller and a rotating motor. The wolf tooth roller is rotatably arranged on the top of the chute, and the end of the wolf tooth roller shaft is transmission-connected to the rotating motor.

[0016] Beneficial effect: The rotating wolf tooth roller can break up all the sintered ash transported by the conveyor belt, so that the magnetic impurities contained in the sintered ash are completely exposed, making it easier to remove and collect impurities.

[0017] Furthermore, the wolf teeth on the wolf tooth roller are all smooth structures.

[0018] Beneficial effect: Prevents sintering ash from adhering to the wolf's teeth and ensures that all sintering ash falls downwards.

[0019] Furthermore, the conveyor belt includes a conveyor belt body and frames on both sides of the conveyor belt body, and the chute is fixedly connected to the frames of the conveyor belt through a support frame.

[0020] Beneficial effect: providing a fixing method for the chute, so that the chute and the conveyor belt frame are connected into a whole, and the structure is more stable.

[0021] Furthermore, a vibration device is provided at the bottom of the chute.

[0022] Beneficial effect: Prevents sintered ash from accumulating on the chute. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is a further detailed description of a sintered ash magnetic impurity removal device of the present invention in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figure 1-2 As shown, the utility model is a sintered ash magnetic impurity removal device, comprising a first impurity removal mechanism arranged above the conveyor belt 1 and a second impurity removal mechanism arranged below the conveyor belt 1, the first impurity removal mechanism comprising a first magnet 3, the first magnet 3 being arranged above the end of the conveyor belt 1, and a gap for the sintered ash to pass through being left between the first magnet 3 and the conveyor belt 1, the second impurity removal mechanism comprising a chute 5 arranged at the bottom of the discharge port of the conveyor belt 1 and arranged downwardly, a scattering component being arranged at the top of the chute 5, a second magnet 8 being arranged at the lower end of the chute 5, the second magnet 8 and the chute 5 groove There is a gap between the bottom and the conveyor belt 1 for the sintered ash to pass through. When the conveyor belt 1 is conveying the sintered ash, the first impurity removal mechanism above the conveyor belt 1 can remove the magnetic impurities on the surface of the sintered ash. When the sintered ash enters the chute 5, the breaking up component at the upper end of the chute 5 can break up the sintered ash, so that the magnetic impurities inside the agglomerated sintered ash are completely exposed, and then removed by the second magnet 8 at the lower end of the chute 5 to ensure that all the magnetic impurities in the sintered ash are completely removed. In order to ensure the removal effect, the first magnet 3 and the second magnet 8 in the embodiment are both cylindrical structures and can both rotate.

[0028] Specifically, the conveyor belt 1 includes a conveyor belt body and frames on both sides of the conveyor belt body. Supports 2 are fixedly provided on the frames on both sides of the front and rear ends of the conveyor belt 1. A first rotating shaft is rotatably arranged between the supports 2 on the front and rear sides. The first magnet 3 is fixedly sleeved on the first rotating shaft, and the end of the first rotating shaft is connected to the first motor 4 for transmission. A second rotating shaft is rotatably arranged between the trough walls at the lower end of the chute 5. The second magnet 8 is fixedly sleeved on the second rotating shaft, and the end of the second rotating shaft is connected to the second motor 9 for transmission. On the one hand, the rotation can extend the adsorption area of ​​the magnet. When the cylindrical structures of the first magnet 3 and the second magnet 8 rotate, the outer curved surfaces can adsorb magnetic impurities, which is increased compared to the fixed non-rotating magnet structure. The rotation of the magnet can reduce the amount of magnetic impurities attached to the magnet, and at the same time avoid the excessive attachment of magnetic impurities that affects the passage of sintered ash; on the other hand, as the magnetic impurities adhere, the adsorption force of the magnetic surface separated by the magnetic impurities decreases, and the rotation can keep the adsorption force of the magnet on the magnetic impurities at a relatively high level, and will not reduce the adsorption force as the thickness of the magnetic impurities increases, thereby ensuring the impurity removal effect of the magnetic impurities; the lower end of the bottom of the chute 5 is provided with a slot that is right-open and transparent up and down, and the second magnet 8 is rotatably arranged in the slot, and the sintered ash can flow directly onto the second magnet 8 along the chute 5. Compared with the side adsorption method, the contact area between the sintered ash and the second magnet 8 is increased, thereby enhancing the impurity removal effect of the second magnet 8.

[0029] In this embodiment, the breaking up component includes a wolf tooth roller 6 and a rotating motor 7. The wolf tooth roller 6 is rotatably set at the top of the chute 5. The end of the wolf tooth roller 6 shaft is transmission-connected to the rotating motor 7. The rotating wolf tooth roller 6 can break up all the sintered ash conveyed by the conveyor belt 1, so that the magnetic impurities wrapped inside the sintered ash are completely exposed, which is convenient for the second magnet 8 below to remove impurities and collect them; the wolf teeth on the wolf tooth roller 6 are all smooth structures to prevent the sintered ash from adhering to the wolf teeth, ensuring that all the sintered ash falls down.

[0030] In this embodiment, the chute 5 is fixedly connected to the frame of the conveyor belt 1 through a support frame 10, so that the chute 5 and the frame of the conveyor belt 1 are connected into a whole, and the structure is more stable; at the same time, a vibration device 11 is provided at the bottom of the chute 5 to prevent the accumulation of sintered ash when the sintered ash is transported on the chute 5.

[0031] The utility model provides a sintered ash magnetic impurity removal device with the following advantages: first, the provision of a breaking up component can break up the agglomerated sintered ash, so that the magnetic impurities on the surface and inside of the sintered ash are completely removed, and the impurity removal effect is thorough; second, the structure of the chute 5 is relatively simple and easy to manufacture, and the first impurity removal mechanism on the conveyor belt 1 and the second impurity removal mechanism below the conveyor belt 1 are also easy to process and have strong practicality; third, the first magnet 3 and the second magnet 8 are both cylindrical structures, which are relatively convenient to operate during the subsequent collection and processing of magnetic impurities and the maintenance of the magnets.

[0032] In the above embodiment, the first magnet and the second magnet are both cylindrical structures. In other embodiments, the first magnet and the second magnet may not be cylindrical structures, but may be rectangular blocks.

[0033] In the above embodiment, both the first magnet and the second magnet are capable of rotating. In other embodiments, the first magnet and the second magnet may not rotate.

[0034] In the above embodiment, a slot with a right opening and transparent top and bottom is provided at the lower end of the bottom of the chute, and the second magnet is rotatably arranged in the slot. In other embodiments, the bottom of the chute is not provided with a slot, and the second magnet is rotatably arranged between the slot walls on both sides in a conventional manner.

[0035] In the above embodiment, the chute is fixedly connected to the frame of the conveyor belt via a support frame. In other embodiments, a separate frame may be provided for the chute.

[0036] In the above embodiment, a vibration device is provided at the bottom of the chute. In other embodiments, no vibration device is provided at the bottom of the chute.
