Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and more specifically, to a screening device for iron ore powder production. Background Technology

[0002] Screening devices are crucial equipment in iron ore powder production. Their main function is to classify iron ore powder according to particle size to meet the requirements of subsequent processes. The working principle of the screening device is to utilize the flow characteristics of materials of different particle sizes on the screen to separate materials that meet the requirements. During operation, when iron ore powder enters the screening device through the feeding device, the vibrating motor drives the screen to vibrate. During the vibration process, iron ore powder particles are thrown up and down on the screen. Smaller particles, under the combined action of gravity and vibration, pass through the screen pores and are discharged from the qualified product outlet. Larger particles, unable to pass through the screen, move along the screen surface to the unqualified product outlet and are discharged, thus achieving the screening of iron ore powder. Since iron ore powder of different qualities needs to be discharged through different outlets, it is necessary to perform a discharge separation operation for iron ore powder.

[0003] In related technologies, during the use of screening devices, the iron ore powder after screening is generally separated and discharged by installing discharge hoppers connected to different screens on one side of the screening frame.

[0004] However, in the current use of screening devices, the discharge hoppers are generally installed at different positions on one side of the screening device. Since the space on one side of the screening device is limited, it is difficult to set up multiple conveying devices for conveying iron ore powder of different qualities at the discharge end of the screening device, which affects the flexibility and adaptability of the screening device in terms of material discharge.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a screening device for iron ore powder production, including a screening machine body 1 and a discharge extension mechanism. A screen 2 is installed inside the screening machine body 1, and discharge hoppers 3 are installed on both sides of the right side of the screening machine body 1. This provides a medium for extending the discharge position of the discharge hoppers 3, so that the user can extend the discharge position of the discharge hoppers 3 to a suitable position according to the discharge and conveying requirements of the iron ore powder after screening by the screening machine body 1. This avoids the situation where the discharge positions of the discharge hoppers 3 are relatively concentrated, making it difficult for external iron ore powder conveying equipment to convey the iron ore powder discharged from different discharge hoppers 3. Therefore, it improves the discharge flexibility and adaptability of the screening machine body 1 and the discharge hoppers 3.

[0031] Reference Figures 1-4 In a preferred embodiment, the discharge extension mechanism includes a material cylinder 4, which is movably connected to the bottom of the discharge hopper 3. An extension cylinder 5 is movably connected inside the material cylinder 4. A sleeve 6 is movably connected to the outside of the discharge hopper 3. The bottom of the sleeve 6 is fixedly connected to the top of the material cylinder 4. A fixing frame 7 located at the bottom of the sleeve 6 is fixedly connected to the top of the inner side of the material cylinder 4. An extension clamping mechanism is located on the outside of the top of the material cylinder 4. By holding the material cylinder 4, the sleeve 6 is moved to fit onto the outside of the discharge hopper 3, establishing a connection between the material cylinder 4 and the discharge hopper 3. Then, according to the conveying position requirements of the external iron ore powder conveying equipment, the extension cylinder 5 is moved outwards to clamp the discharge hopper. The discharge position of hopper 3 is extended so that multiple external iron ore powder conveying devices can convey the iron ore powder discharged through hopper 3 at appropriate positions. The extended clamping mechanism includes clamping port 8, clamping seat 9, and clamping rod 10. Clamping port 8 is opened on the outside of the top of the material cylinder 4. Clamping seat 9 is movably connected to the inside of clamping port 8. Clamping rod 10 is fixedly connected to the top of clamping seat 9. It can provide the user with a medium for clamping the extended cylinder 5, which makes it convenient for the user to clamp and position the extended cylinder 5 and the material cylinder 4 after the extension is moved. This avoids the situation where the extended cylinder 5 is difficult to position during use, thus improving the positioning convenience of the extended cylinder 5.

[0032] Reference Figures 2-4In a preferred embodiment, a pressure plate 11 located inside the clamping rod 10 is movably connected to the top of the material cylinder 4. An anti-slip pad 12 that contacts the discharge hopper 3 is fixedly connected to the bottom of the pressure plate 11. This can work with the fixing frame 7 to apply pressure and clamp the material cylinder 4 and the discharge hopper 3, avoiding the situation where the material cylinder 4 is difficult to connect stably to the discharge hopper 3. Therefore, the convenience of connecting the material cylinder 4 and the discharge hopper 3 is improved. A connecting cylinder 13 is fixedly connected to the top of the material cylinder 4. Both sides of the connecting cylinder 13 are provided with connecting ports 14. The clamping rod 10 and the pressure plate 11 pass through the connecting ports 14 into the interior of the connecting cylinder 13. This can connect the clamping rod 10, the pressure plate 11 and the material cylinder 4, avoiding the situation where the clamping rod 10 and the pressure plate 11 separate from the material cylinder 4 during use. Therefore, the connection effect of the clamping rod 10, the pressure plate 11 and the material cylinder 4 is improved.

[0033] Reference Figures 2-4 In a preferred embodiment, lifting rings 15 are movably connected to both the top and bottom of the connecting cylinder 13. The surfaces of the lifting rings 15 are fixedly connected to the surfaces of the clamping rod 10 and the pressure plate 11, respectively. A lifting frame 16 is movably connected inside the lifting rings 15. The lifting connection between the clamping rod 10, the pressure plate 11, and the connecting cylinder 13 can be raised and lowered through the connection port 14 to prevent offset. This avoids the situation where the connecting cylinder 13 cannot stably connect the clamping rod 10 and the pressure plate 11, thus improving the connection stability between the clamping rod 10, the pressure plate 11, and the connecting cylinder 13. A magnetic ring 17 is fixedly connected to the top of the lifting ring 15. A magnetic suction ring 18 is magnetically connected to the top of the magnetic ring 17. The top of the magnetic suction ring 18 is fixedly connected to the surface of the lifting frame 16, which can perform magnetic positioning between the lifting ring 15 and the lifting frame 16. This avoids the situation where the lifting ring 15 and the lifting frame 16 are in a free-moving state, making it difficult for the subsequent stud 20 to apply thread lifting force to the lifting ring 15 through the lifting frame 16. This improves the connection flexibility between the lifting ring 15 and the lifting frame 16.

[0034] Reference Figures 2-4 In a preferred embodiment, a screw hole 19 is provided on the top of the lifting frame 16, and a stud 20 connected to the connecting cylinder 13 is threaded inside the screw hole 19. The lifting frame 16, in conjunction with the lifting ring 15, can apply lifting and lowering clamping force to the clamping rod 10 and the pressure plate 11, avoiding the situation where it is difficult to apply force to clamp the clamping rod 10 and the pressure plate 11 during use. Therefore, the ease of applying force to clamp the clamping rod 10 and the pressure plate 11 is improved. A connecting groove 21 is provided at the bottom of the inner wall of the connecting cylinder 13, and a connecting seat 22 is magnetically connected inside the connecting groove 21. The top of the connecting seat 22 is fixedly connected to the bottom of the stud 20, which can provide connection support between the stud 20 and the connecting cylinder 13, avoiding the bottom of the stud 20 from shaking during use. Therefore, the connection stability between the stud 20 and the connecting cylinder 13 is improved.

[0035] Specifically, the working process or working principle of this iron ore powder screening device is as follows: During use, based on the actual need for the iron ore powder to be screened by the screen 2 and discharged through the discharge hopper 3, and the location requirements of the external iron ore powder conveying equipment, first, the extended cylinder 5 is moved outwards by hand to adjust the discharge position of the cylinder 4, preparing for subsequent extension of the discharge hopper 3. Then, the cylinder 4 is held to drive the sleeve 6 to be fitted onto the outside of the discharge hopper 3, and the top of the fixing frame 7 contacts the bottom of the discharge hopper 3. Subsequently, the stud 20 is rotated through the screw hole 1. 9. Apply threaded thrust to the lifting frame 16. At this time, the connecting seat 22 rotates inside the connecting groove 21 following the stud 20, providing connection and support between the stud 20 and the connecting cylinder 13. Simultaneously, since the magnetic ring 17 and the magnetic suction ring 18 are strongly magnetically connected, the lifting frame 16 and the lifting ring 15 can be magnetically positioned. As the stud 20 pushes the lifting frame 16, the lifting ring 15, in conjunction with the lifting frame 16, drives the pressing rod 10 and the pressure plate 11 to move downwards respectively. During this process, the pressing rod 10 drives the pressing seat 9 through the pressing port 8, penetrating the material cylinder 4 and the extension. The top of cylinder 5 contacts and abuts against the material cylinder 4, performing abutment positioning between the extension cylinder 5 and the material cylinder 4. After the abutment rod 10 drives the abutment seat 9 to move down and abut against the material cylinder 4, the stud 20 continues to rotate while pushing the pressure plate 11. The lifting ring 15, which is fixedly connected to the abutment rod 10, is affected by the resistance that the abutment rod 10 cannot move down further, and rotates freely on the outside of the lifting frame 16. This allows the stud 20 to continue rotating, and through the lifting frame 16 and the lifting ring 15, pushes the pressure plate 11 downward. When the pressure plate 11 drives the anti-slip pad 12 to contact and abut against the top of the discharge hopper 3, it cooperates with the fixing frame 7. The material cylinder 4 and the discharge hopper 3 are clamped and fixed together. The material cylinder 4 and the extension cylinder 5 are positioned at the discharge position of the discharge hopper 3. The discharge position of the discharge hopper 3 is extended. After the iron ore powder is screened by the screen 2 and discharged from the screening machine body 1 through different discharge hoppers 3, it enters the interior of different material cylinders 4 through the sleeve 6. At this time, the extension cylinder 5 guides the iron ore powder entering the rear side of the material cylinder 4, guiding the iron ore powder to the conveying end of different iron ore powder conveying equipment, so as to meet the needs of multiple external iron ore powder conveying equipment to convey iron ore powder of different qualities.

[0036] It should be noted that the screening machine body 1, screen 2 and discharge hopper 3 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
