Description

Technical Field

[0002] In the iron ore processing industry, roasting and magnetization is a key process for improving the magnetic separation performance of iron ore and realizing efficient resource utilization. The core objective of this process is to ensure that iron ore particles or powder come into full contact with reducing gases, thereby completing full roasting. Its effect directly determines the quality of subsequent magnetization modification of iron ore and its industrial application value.

[0003] In actual operation, existing iron ore roasting and magnetization equipment lacks an efficient material dispersion structure inside the equipment. Iron ore particles and powders are prone to agglomeration inside the equipment, and their falling trajectory is singular, resulting in a limited contact area between the material and the reducing gas and poor contact uniformity, thus causing incomplete roasting.

[0023] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0024] Please see Figure 1-5 This utility model discloses an iron ore roasting and magnetization device, comprising a base 1, a column 2, a support plate 3, a rotating shell 4, and a heating device 5. The column 2 is fixedly installed at the four corners of the upper surface of the base 1, the support plate 3 is fixedly installed at the top of the column 2, the rotating shell 4 is rotatably mounted on the support plate 3, the heating device 5 is fixedly mounted on the base 1, the output end of the heating device 5 is fixedly mounted with a heating rod 6, and the heating rod 6 passes through the support plate 3 and extends into the interior of the rotating shell 4. The upper and lower sides of the inner wall of the rotating shell 4 are fixedly mounted with outer rotating rings 7, the support plate 3 is rotatably mounted with a connecting cylinder 8, and the connecting cylinder 8 is movably sleeved on the outside of the heating rod 6. The middle of the outer wall of the connecting cylinder 8 is fixedly mounted with an inner rotating ring 9, and the top of the connecting cylinder 8 is fixedly mounted with a turntable 10.

[0025] After the iron ore particles or powder enter the rotating shell 4, they are first evenly dispersed and fall under the rotation of the rotating disk 10. Then they fall onto the upper outer rotating ring 7. Under the reverse rotation of the upper outer rotating ring 7, the iron ore particles and powder are further dispersed. Then, since the inner rotating ring 9 and the rotating disk 10, and the lower outer rotating ring 7 and the upper outer rotating ring 7 move in the same direction, the iron ore particles and powder will repeat the above movement at the inner rotating ring 9 and the lower outer rotating ring 7, and be repeatedly subjected to opposite forces, continuously dispersed and falling, avoiding the agglomeration of iron ore particles and powder, and can fully contact with reducing gas to achieve full roasting.

[0026] The inner diameter of the outer rotating ring 7 is smaller than the outer diameter of the turntable 10 and the inner rotating ring 9. When the ore particles and powder enter the rotating shell 4, they cannot pass directly through the inner ring of the upper outer rotating ring 7 due to the limitation of the outer diameter of the turntable 10. As a result, they fall onto the ring surface of the upper outer rotating ring 7 first. Then, when the ore particles and powder fall down through the inner ring of the upper outer rotating ring 7, they are caught by the inner rotating ring 9, which has a larger outer diameter. Finally, the falling ore particles and powder cannot pass through the inner ring of the lower outer rotating ring 7 due to the limitation of the outer diameter of the inner rotating ring 9. They fall onto the ring surface of the lower outer rotating ring 7. This achieves the step-by-step catching and falling of ore particles and powder in the rotating shell 4, extending their residence path and time in the rotating shell 4.

[0027] A drive motor 11 is fixedly installed on the lower surface of the support plate 3. The output end of the drive motor 11 passes through the support plate 3 and is fixedly installed with a drive gear 12. An external gear 13 is fixedly installed at the lower end of the rotating shell 4, and the drive gear 12 meshes with the internal teeth of the external gear 13. An internal gear 14 is fixedly installed at the lower end of the connecting cylinder 8, and the drive gear 12 meshes with the internal gear 14.

[0028] When the drive motor 11 operates and controls the drive gear 12 to rotate, it will simultaneously drive the external gear 13 and the internal gear 14 to rotate. According to the characteristics, the external gear 13 will rotate in the same direction as the drive gear 12, and the internal gear 14 will rotate in the opposite direction to the drive gear 12. Therefore, the external gear 13 and the internal gear 14 rotate in opposite directions, which also causes the rotating shell 4 and the connecting cylinder 8 to rotate in opposite directions, thereby causing the outer rotating ring 7 to rotate in the opposite direction to the inner rotating ring 9 and the turntable 10.

[0029] Arc-shaped guide rods 15 are fixedly provided on the turntable 10, the inner rotating ring 9 and the outer rotating ring 7, and the arc direction of the arc-shaped guide rod 15 on the outer rotating ring 7 is opposite to the arc direction of the arc-shaped guide rod 15 on the turntable 10 and the inner rotating ring 9.

[0030] The movement of the turntable 10, inner rotating ring 9 and outer rotating ring 7, in conjunction with the action of the reverse arc-shaped guide rod 15, can form a directional flow and impact on iron ore particles and powder, allowing the particles and powder to be pushed apart in different directions, which helps to disperse iron ore particles or powder.

[0031] The rotating shell 4 has a feed inlet 22 at the center of its top for feeding iron ore particles or powder. A reducing gas input pipe is placed inside the feed inlet 22, and a nozzle is installed at the end of the input pipe to spray the reducing gas onto the iron ore particles or powder or spray it periodically. This not only facilitates the dispersion of the iron ore particles and powder, but also promotes their full contact with the reducing gas. In addition, when feeding materials into the feed inlet 22 or connecting the reducing gas input pipe, the feed inlet 22 must be sealed to prevent the reducing gas from leaking out of the feed inlet 22.

[0032] Support rods 16 are evenly fixedly installed on the support plate 3. Hollow rings 17 are fixedly installed on the inner wall of the support rods 16 and are attached to the outer surface of the rotating shell 4.

[0033] The hollow ring 17 can limit the position of the rotating shell 4, preventing the rotating shell 4 from shifting or shaking during operation, and ensuring the stability of the equipment operation.

[0034] The lower surface of the lower outer rotating ring 7 is evenly provided with air outlets 18, and the outer end of the air outlet 18 is connected to the hollow ring 17. An air outlet pipe 19 is fixedly provided on the outer side of the hollow ring 17, and the outer end of the air outlet pipe 19 passes through and extends to the outside of the support rod 16.

[0035] The gas after the reaction is first discharged from the outlet 18 on the lower surface of the outer rotating ring 7, and then enters the hollow ring 17 through the outlet 18. Finally, it is discharged through the outlet pipe 19 set on the outer side of the hollow ring 17. An air extraction device is set at the outer end of the outlet pipe 19 to promote the flow of gas in the rotating shell 4.

[0036] Support blocks 20 are evenly fixedly installed on the support plate 3, and a collection box 21 is fixedly installed on the top of the support block 20, and the collection box 21 is located inside the rotating shell 4.

[0037] The collection box 21 can recover the falling iron ore particles or powder. The collection box 21 is located outside the heating rod 6 and can continue to roast the falling iron ore particles or powder.

[0038] For different application scenarios, a conveying pipe can be added to the lower end of the collection box 21 to convey the reacted iron ore particles or powder to the outside, thereby realizing the continuous addition and continuous processing of iron ore particles or powder in the equipment and ensuring the continuous operation capability of the equipment.

[0039] When using this iron ore roasting and magnetization equipment: First, start the drive motor 11 to drive the drive gear 12 to rotate. The rotation of the drive gear 12 drives the outer gear 13 and the inner gear 14 to rotate in opposite directions, thereby causing the rotating shell 4 and the connecting cylinder 8 to rotate in opposite directions. Then, iron ore particles or powder and reducing gas are put in through the feed port 22. The iron ore particles or powder are first evenly dispersed and fall under the rotation of the turntable 10, and then fall onto the upper outer rotating ring 7. Under the reverse rotation of the upper outer rotating ring 7, the particles and powder are further dispersed. Then, the above movement is repeated at the inner rotating ring 9 and the lower outer rotating ring 7, repeatedly subjected to opposite forces, so as to achieve the dispersion and fall of the particles and powder, allowing them to fully contact the reducing gas and achieve full roasting. During the process, the gas after reaction enters the hollow ring 17 through the gas outlet 18 on the lower surface of the lower outer rotating ring 7, and finally is discharged through the gas outlet pipe 19. The iron ore particles or powder after reaction fall into the collection box 21.

[0040] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
