Description

Technical Field

[0001] This application relates to mineral processing, and in particular to a system for recovering low-grade, weakly magnetic iron ore. Background Technology

[0002] Low-grade iron ore means that the iron content in the ore is relatively low, and the difficulty and cost of mining and utilization are usually higher. Weakly magnetic iron ore indicates that the iron minerals in the ore are less magnetic, and cannot be easily enriched by conventional magnetic separation methods like strongly magnetic ores. This recovery system generally integrates multiple technologies and equipment, and may include a series of process steps such as crushing, feeding, magnetic separation, flotation, and gravity separation. Through the coordinated operation of these steps, the iron minerals in low-grade weakly magnetic iron ore are separated from gangue and other impurities, improving the grade and recovery rate of iron concentrate, realizing efficient use of resources, reducing resource waste, and also helping to reduce environmental impact.

[0003] In the feeding process, the existing conveying and feeding devices lack secondary vibration separation function. When feeding crushed materials, they cannot be separated and filtered. Large particles in the materials may be mixed in the subsequent process, which will reduce the efficiency of magnetic separation, flotation and other links and affect the overall recovery effect. In order to solve the above problems, a low-grade weak magnetic iron ore recovery system is proposed. Utility Model Content

[0004] The purpose of this application is to provide a low-grade weak magnetic iron ore recovery system with advantages such as vibration filtration. It solves the problem that the crushed material cannot be separated and filtered, and large particles in the material may be mixed in the subsequent process, resulting in reduced efficiency of magnetic separation, flotation and other links, and affecting the overall recovery effect.

[0005] The low-grade weakly magnetic iron ore recovery system provided in this application adopts the following technical solution: it includes a feeding diversion frame and a bottom plate. A filter plate is movably connected inside the feeding diversion frame through a pin shaft. A connecting plate is fixedly connected to the side of the filter plate. A vibration box is fixedly connected inside the feeding diversion frame. The vibration box is located at the bottom of the connecting plate.

[0006] The vibration box has two through holes at the top. A dual-axis motor is fixedly connected to the inner side of the vibration box. A rotating rod is fixedly connected to the output end of the dual-axis motor. One end of the rotating rod is rotatably connected to the inner side of the vibration box. A rotating cam is fixedly connected to the surface of the rotating rod. A protruding plate is fixedly connected to the side of the vibration box. A limit spring is fixedly connected to the top of the protruding plate. The top of the limit spring is fixedly connected to the top of the connecting plate. The bottom end of the connecting plate is located at the side discharge port. A side discharge port is opened on the side of the feeding diversion frame. A feeding cylinder is fixedly connected to one side of the bottom of the feeding diversion frame. A support rod is fixedly connected to one side of the top of the base plate. A fixed rod is fixedly connected to the top of the support rod. Two electric push rods are movably connected to one side of the top of the base plate through a pin. A support plate is movably connected to the top of the electric push rod through a pin. The bottom side of the support plate is movably connected to the top of the fixed rod through a pin.

[0007] By adopting the above technical solution, and by setting up a filter plate and a dual-axis motor, the operation of the dual-axis motor can drive the rotating rod to rotate, which can cause the rotating cam to apply periodic pressure to the connecting plate, making the filter plate vibrate at high frequency. Through the vibrating filter plate, the crushed material can be effectively separated. Large particles will be blocked and discharged from the side outlet, while fine materials that meet the requirements will pass through the filter plate and enter the feeding cylinder, thereby ensuring the material quality of subsequent processes. At the same time, the design of the limit spring can ensure that the connecting plate remains stable during vibration, avoiding equipment damage or reduction in filtration effect due to excessive displacement. By setting up an electric push rod, the cooperation between the electric push rod and the support plate can adjust the angle of the feeding diversion frame according to actual needs, thereby optimizing the material flow path and improving the adaptability and flexibility of the overall system.

[0008] Preferably, two fixing blocks are fixedly connected to the bottom of the feeding diversion frame, and a contact roller is movably connected between the two fixing blocks by a pin.

[0009] By adopting the above technical solution and setting contact rollers, a power contact point can be provided for the overall vibration of the feeding and diverting frame. During the operation of the equipment, the contact rollers cooperate with the external drive mechanism to transfer the vibration energy to the feeding and diverting frame, causing it to oscillate regularly, which can promote the uniform distribution of materials and improve the material distribution efficiency. At the same time, the contact rollers adopt a rotatable design, which can reduce frictional losses between them and the drive mechanism.

[0010] Preferably, a vertical plate is fixedly connected to one side of the top of the support plate, and a protective shell is fixedly connected to one side of the top of the support plate;

[0011] By adopting the above technical solutions and with the help of the protective shell, additional protection can be provided for the operation of the equipment, which can isolate the intrusion of external dust and impurities and ensure a clean and safe working environment for internal components.

[0012] Preferably, a rotating rod is tightly nested between the upright plate and the protective shell via a bearing, and a contact cam and a first gear are fixedly connected to the surface of the rotating rod, with the surface of the contact cam overlapping the surface of the contact roller;

[0013] By adopting the above technical solution, a more flexible transmission effect can be achieved through the cooperation of the rotating rod and the contact cam, while ensuring the stability of power transmission during equipment operation.

[0014] Preferably, a rotary motor is fixedly connected to the inner side of the protective shell, and a second gear is fixedly connected to the output end of the rotary motor, wherein the first gear and the second gear mesh with each other;

[0015] By adopting the above technical solution, and through the cooperation of the rotary motor and the first gear, more precise power output control can be achieved, which can improve the overall operating efficiency and stability of the equipment.

[0016] Preferably, the outer side of the protective shell is provided with heat dissipation holes;

[0017] By adopting the above technical solution and setting heat dissipation holes, the heat generated inside the protective shell can be effectively dissipated, thereby ensuring that the equipment will not be affected by excessive temperature during long-term operation.

[0018] Preferably, a fixed cylinder is fixedly connected to each of the four top corners of the support plate, and a connecting rod is fixedly connected to each of the four bottom corners of the feeding diversion frame. The bottom end of the connecting rod is located in the fixed cylinder and is fixedly connected to a limiting plate, which is slidably connected inside the fixed cylinder.

[0019] By adopting the above technical solution, the connection stability between the support plate and the feeding diversion frame can be effectively enhanced through the cooperation of the fixed cylinder and the limiting plate. At the same time, it can be ensured that the equipment will not loosen due to vibration or external force during operation. In addition, the sliding design of the limiting plate allows the connecting rod to be flexibly adjusted within a certain range, thereby adapting to the needs of different working conditions and further improving the applicability and ease of operation of the equipment.

[0020] Preferably, a connecting spring is fixedly connected to the bottom of the inside of the fixed cylinder, and the top of the connecting spring is fixedly connected to the bottom of the limiting plate;

[0021] By adopting the above technical solution and setting a connecting spring, the buffering effect between the fixed cylinder and the limiting plate can be further enhanced, effectively reducing the impact force caused by vibration during equipment operation, thereby improving the stability and durability of the overall structure.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This low-grade, weakly magnetic iron ore recovery system incorporates a filter plate and a dual-shaft motor. The dual-shaft motor drives a rotating rod, which in turn applies periodic pressure to the connecting plate via a rotating cam. This causes the filter plate to vibrate at high frequency. The vibrating filter plate effectively separates the crushed material. Large particles are blocked and discharged from the side outlet, while smaller, suitable particles pass through the filter plate and enter the feed cylinder, ensuring material quality in subsequent processes. The design of limit springs ensures the stability of the connecting plate during vibration, preventing damage or reduced filtration efficiency due to excessive displacement. An electric push rod, working in conjunction with a support plate, allows adjustment of the feed distribution frame angle to optimize material flow and improve the overall system's adaptability and flexibility.

[0034] The following is in conjunction with the appendixFigure 1 - Appendix Figure 5 This application will be described in further detail below.

[0035] Example 1: A low-grade weakly magnetic iron ore recovery system, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 The feed diversion frame 1 and the base plate 3 are included. A filter plate 101 is movably connected inside the feed diversion frame 1 via a pin. A connecting plate 102 is fixedly connected to the side of the filter plate 101. A vibration box 2 is fixedly connected inside the feed diversion frame 1. The vibration box 2 is located at the bottom of the connecting plate 102.

[0036] Two through holes 201 are provided on the top of the vibration box 2. A dual-axis motor 202 is fixedly connected to the inner side of the vibration box 2. A rotating rod 203 is fixedly connected to the output end of the dual-axis motor 202. One end of the rotating rod 203 is rotatably connected to the inner side of the vibration box 2. A rotating cam 204 is fixedly connected to the surface of the rotating rod 203. A protruding plate 109 is fixedly connected to the side of the vibration box 2. A limit spring 1010 is fixedly connected to the top of the protruding plate 109. The top end of the limit spring 1010 is fixedly connected to the top of the connecting plate 102. The bottom end of the connecting plate 102 is located at the side discharge port 104. The side discharge port 104 is opened on the side of the feeding diversion frame 1. The bottom side of the feeding diversion frame 1 is fixedly connected to the feed cylinder 103. The top side of the bottom plate 3 is fixedly connected to the support rod 301. The top of the support rod 301 is fixedly connected to the fixing rod 302. The top side of the bottom plate 3 is movably connected to two electric push rods 303 through a pin. The top of the electric push rods 303 is movably connected to the support plate 304 through a pin. The bottom side of the support plate 304 is... The filter plate 101 is movably connected to the top of the fixed rod 302 via a pin. When the filter plate 101 is connected to the dual-axis motor 202, the operation of the dual-axis motor 202 drives the rotating rod 203 to rotate. This causes the rotating cam 204 to apply periodic pressure to the connecting plate 102, resulting in high-frequency vibration of the filter plate 101. The vibrating filter plate 101 effectively separates the crushed material. Large particles are blocked and discharged from the side outlet 104, while fine particles that meet the requirements pass through the filter plate 101 and enter the feed cylinder 103, ensuring the material quality in subsequent processes. Simultaneously, the design of the limit spring 1010 ensures the stability of the connecting plate 102 during vibration, preventing equipment damage or reduced filtration efficiency due to excessive displacement. The electric push rod 303, in conjunction with the support plate 304, allows adjustment of the angle of the feed diversion frame 1 according to actual needs, thereby optimizing the material flow path and improving the overall system's adaptability and flexibility.

[0037] Please see Figure 5Two fixed blocks 107 are fixedly connected to the bottom of the feeding diversion frame 1. A contact roller 108 is movably connected between the two fixed blocks 107 via a pin. By setting the contact roller 108, a power contact point can be provided for the overall vibration of the feeding diversion frame 1. During the operation of the equipment, the contact roller 108 cooperates with the external drive mechanism to transmit vibration energy to the feeding diversion frame 1, causing it to oscillate regularly, which can promote uniform material distribution and improve the material distribution efficiency. At the same time, the contact roller 108 adopts a rotatable design, which can reduce frictional loss between it and the drive mechanism. A vertical plate 306 is fixedly connected to one side of the top of the support plate 304, and a protective shell 307 is fixedly connected to one side of the top of the support plate 304. With the cooperation of the protective shell 307, an additional protection can be provided for the operation of the equipment, which can isolate the intrusion of external dust and impurities, ensuring a clean and safe working environment for internal components. The vertical plate 306 and the protective shell 307 are tightly nested together by a bearing to form a rotating... The rotating rod 308 has a contact cam 309 and a first gear 3010 fixedly connected to its surface. The surface of the contact cam 309 overlaps the surface of the contact roller 108. Through the cooperation between the rotating rod 308 and the contact cam 309, a more flexible transmission effect can be achieved, while ensuring the stability of power transmission during equipment operation. A rotary motor 3011 is fixedly connected to the inner side of the protective shell 307. A second gear 3012 is fixedly connected to the output end of the rotary motor 3011. The first gear 3010 and the second gear 3012 mesh with each other. Through the cooperation between the rotary motor 3011 and the first gear 3010, more precise power output control can be achieved, which can improve the overall operating efficiency and stability of the equipment. The outer side of the protective shell 307 has heat dissipation holes. By setting heat dissipation holes, the heat generated inside the protective shell 307 can be effectively dissipated, thereby ensuring that the equipment will not be affected by excessive temperature during long-term operation.

[0038] Please see Figure 3The support plate 304 has four fixed corners at the top, each with a fixed cylinder 305. The feed diversion frame 1 has four fixed corners at the bottom, each with a connecting rod 105. The bottom end of the connecting rod 105 is located within the fixed cylinder 305 and is fixedly connected to a limiting plate 106. The limiting plate 106 is slidably connected within the fixed cylinder 305. Through the cooperation of the fixed cylinder 305 and the limiting plate 106, the connection stability between the support plate 304 and the feed diversion frame 1 is effectively enhanced, ensuring that the equipment will not loosen due to vibration or external forces during operation. Furthermore, the limiting plate 106... The sliding design of 06 allows the connecting rod 105 to be flexibly adjusted within a certain range to adapt to different working conditions, further improving the applicability and ease of operation of the equipment. The bottom of the fixed cylinder 305 is fixedly connected to the connecting spring 4, and the top of the connecting spring 4 is fixedly connected to the bottom of the limiting plate 106. By setting the connecting spring 4, the buffering effect between the fixed cylinder 305 and the limiting plate 106 can be further enhanced, effectively reducing the impact force caused by vibration during the operation of the equipment, thereby improving the stability and durability of the overall structure.

[0039] The implementation principle of this application embodiment is as follows: When in use, people pour the material into the feeding and diversion frame 1, and then start the dual-axis motor 202. The dual-axis motor 202 starts to run, driving the rotating rod 203 and the rotating cam 204 on its surface to rotate. The rotating cam 204 applies periodic pressure to the connecting plate 102, causing the filter plate 101 to vibrate at high frequency, thereby achieving effective separation of materials. Large particles are blocked by the filter plate 101 and discharged through the side outlet 104, while fine materials pass through the filter plate 101 and enter the feeding cylinder 103, ensuring the material quality of subsequent process steps. At the same time, the limiting spring 1010 plays a role in limiting the vibration amplitude of the connecting plate 102, avoiding equipment damage or reduction in filtration effect due to excessive displacement.

[0040] By setting a rotary motor 3011, the operation of the rotary motor 3011 can cause the first gear 3010 to rotate. Through the meshing of the first gear 3010 and the second gear 3012, the rotating rod 308 and the contact cam 309 can be driven to rotate. Then, under the action of the external drive mechanism, the contact roller 108 can transmit the vibration energy to the feeding and diverting frame 1, causing it to oscillate regularly, promoting the uniform distribution of materials, further improving the material distribution efficiency, realizing precise power output control, and ensuring the stability of equipment operation. Among them, the design of heat dissipation holes effectively dissipates the heat inside the protective shell 307, avoiding the impact of excessive temperature on equipment performance.

[0041] The cooperation between the fixed cylinder 305 and the limiting plate 106 enhances the connection stability between the support plate 304 and the feeding diversion frame 1. At the same time, the sliding design of the limiting plate 106 allows the connecting rod 105 to flexibly adjust its position within a certain range to adapt to different working conditions. The connecting spring 4 further enhances the buffering effect between the fixed cylinder 305 and the limiting plate 106, reduces vibration and impact, and enhances the stability and durability of the overall structure.

[0042] By cooperating with the electric push rod 303 and the support plate 304, the angle of the feeding diversion frame 1 can be adjusted according to actual needs, optimizing the material flow path and improving the adaptability and flexibility of the system.
