[0001] This utility model relates to the field of iron ore beneficiation technology, and in particular to a high-frequency vibrating screen for iron ore beneficiation. Background Technology
[0002] Iron ore beneficiation refers to the process of separating iron from other components in iron-bearing ore through physical or chemical methods. Its aim is to improve the grade and purity of iron ore, preparing it for subsequent smelting and utilization. It is a crucial link in the iron ore production chain, directly affecting smelting efficiency and product quality. The goal of beneficiation is to remove unwanted substances and ultimately obtain high-grade iron concentrate, thereby increasing the iron content of the ore, reducing energy consumption and costs during smelting, and enhancing the market competitiveness of the final product.
[0003] High-frequency vibrating screens are required in iron ore beneficiation. They play an important role in iron ore beneficiation, mainly for efficient screening of ore. They achieve material classification through high-frequency vibration. However, in the traditional high-frequency vibrating screen, iron ore is fed onto the screen through the feed hopper, which can easily lead to uneven feeding and affect the efficiency of the initial screening. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a high-frequency vibrating screen for iron ore beneficiation, which aims to improve the problem that when using a traditional high-frequency vibrating screen, the iron ore is fed to its screen through the feed hopper, which easily leads to uneven feeding and thus affects the efficiency of the primary screening.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-frequency vibrating screen for iron ore beneficiation, comprising a support frame, a mounting frame fixedly connected to one side of the support frame, a feed hopper fixedly connected to the top of the mounting frame, a motor fixedly connected to one side of the feed hopper, a rotating shaft fixedly connected to the output end of the motor through one side of the feed hopper, a spiral feeding plate fixedly connected to the outer wall of the rotating shaft, a discharge port provided on one side of the feed hopper, a discharge plate inclinedly provided on one side of the feed hopper, the discharge plate being located at the bottom of the discharge port, and side plates symmetrically fixedly connected to the top of the support frame.
[0006] Preferably, the side plate is L-shaped, and a vibrator is fixedly connected to the side of the side plate that is furthest away from the other side.
[0007] Preferably, a screen is provided on one side of the output end of the vibrator that passes through the side plate, and the screen is located below the feed plate.
[0008] Preferably, springs are uniformly and fixedly connected to the bottom of the screen, and the bottom of the springs is fixedly connected to the bottom of the opposite side of the side plate.
[0009] Preferably, the upper surface of the screen is a stepped screen surface, which includes periodic and continuous peaks and troughs.
[0010] Preferably, a sound-absorbing plate is fixedly connected to one side of the side plate opposite to the screen, and the sound-absorbing plate is located above the screen.
[0011] Preferably, the bracket is provided with a concentrate collection hopper inside, the bottom of the concentrate collection hopper is evenly provided with casters, a push handle is fixedly connected to one side of the concentrate collection hopper, and the concentrate collection hopper is located below the side plate.
[0012] Preferably, a coarse ore collecting hopper is provided on the side of the support away from the mounting frame, and the coarse ore collecting hopper is located below the screen.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the rotating shaft is driven by a motor, which in turn drives the spiral feeding plate to rotate. This allows the iron ore temporarily stored inside the feed hopper to be evenly conveyed through the discharge port to the inclined feeding plate, and then evenly slides onto the surface of the screen. This ensures that the iron ore is evenly conveyed onto the screen, thereby improving the efficiency of the primary screening of iron ore. This solves the problem that in traditional high-frequency vibrating screens, the iron ore is fed onto the screen through the feed hopper, which easily leads to uneven feeding and affects the efficiency of the primary screening.
[0015] 2. In this utility model, the stepped screen surface formed by the periodic and continuous peaks and troughs enhances the travel of iron ore during screening, thereby increasing the fineness of iron ore screening. The sound-absorbing plate absorbs noise, reducing noise disturbance to personnel. The concentrate collected by the concentrate collection hopper temporarily stores the concentrate after screening, and the coarse ore collected by the coarse ore collection hopper temporarily stores the coarse ore remaining on the screen surface, thus improving the practicality of this high-frequency vibrating screen for iron ore beneficiation.

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.
[0022] Reference Figures 1-3 This utility model provides an embodiment of a high-frequency vibrating screen for iron ore beneficiation, comprising a support 1, a mounting frame 5 fixedly connected to one side of the support 1, a feed hopper 3 fixedly connected to the top of the mounting frame 5, a motor 4 fixedly connected to one side of the feed hopper 3, a rotating shaft 19 fixedly connected to the output end of the motor 4 through one side of the feed hopper 3, a spiral feeding plate 18 fixedly connected to the outer wall of the rotating shaft 19, a discharge port 2 provided on one side of the feed hopper 3, a discharge plate 11 inclinedly provided on one side of the feed hopper 3, the discharge plate 11 being located at the bottom of the discharge port 2, side plates 6 symmetrically fixedly connected to the top of the support 1; the side plates 6 are L-shaped, a vibrator 7 fixedly connected to the side of the side plates 6 that are far apart from each other; a screen 10 is provided through one side of the output end of the vibrator 7 through one side of the side plate 6, the screen 10 being located below the discharge plate 11; springs 13 are evenly fixedly connected to the bottom of the screen 10, the bottom of the springs 13 being fixedly connected to the bottom of the opposite side of the side plates 6.
[0023] Specifically, the iron ore is temporarily stored in the feed hopper 3. The operation of the motor 4 drives the rotating shaft 19 to rotate, which in turn drives the spiral feeding plate 18 to rotate. This allows the iron ore temporarily stored in the feed hopper 3 to be evenly conveyed to the inclined discharge plate 11 through the discharge port 2, and then evenly slides onto the surface of the screen 10. This ensures that the iron ore is evenly conveyed onto the screen 10, thereby improving the efficiency of the initial screening of iron ore. This solves the problem that in traditional high-frequency vibrating screens, the iron ore is fed to the screen through the feed hopper, which easily leads to uneven feeding and affects the efficiency of the initial screening. The operation of the vibrator 7 drives the screen 10 to vibrate, and the spring 13 expands the amplitude of the screen 10, thereby screening the iron ore on the surface of the screen 10.
[0024] The upper surface of the screen 10 is a stepped screen surface, which includes periodic continuous peaks 16 and troughs 17; a sound-absorbing plate 8 is fixedly connected to the opposite side of the side plate 6, and the sound-absorbing plate 8 is located above the screen 10; a concentrate collection hopper 9 is provided inside the support 1, and universal wheels 14 are evenly arranged at the bottom of the concentrate collection hopper 9. A push handle 15 is fixedly connected to one side of the concentrate collection hopper 9, and the concentrate collection hopper 9 is located below the side plate 6; a coarse ore collection hopper 12 is provided on the side of the support 1 away from the mounting frame 5, and the coarse ore collection hopper 12 is located below the screen 10.
[0025] Specifically, the stepped screen surface formed by the periodic continuous peaks 16 and troughs 17 enhances the travel of iron ore during screening on the screen 10, thereby increasing the fineness of iron ore screening. The sound-absorbing plate 8 absorbs noise during screening, reducing noise disturbance to personnel. The concentrate collection hopper 9 temporarily stores the concentrate screened by the screen 10. The casters 14 and push handle 15 allow it to be moved. The coarse ore collection hopper 12 temporarily stores the coarse ore remaining on the surface of the screen 10, thus improving the practicality of this high-frequency vibrating screen for iron ore beneficiation.
[0026] Working principle: During use, the iron ore to be screened is conveyed into the feed hopper 3. Then, the motor 4 drives the rotating shaft 19 to rotate, which in turn drives the screw feeder 18 to rotate. The iron ore temporarily stored in the feed hopper 3 is evenly conveyed through the discharge port 2 to the inclined discharge plate 11, and then evenly slides onto the surface of the screen 10, thus evenly conveying the iron ore onto the screen 10. Then, the vibrator 7 drives the screen 10 to vibrate, and the vibration is amplified by the spring 13. The amplitude of the large screen 10 is used to screen the iron ore on the surface of the screen 10. The stepped screen surface formed by the periodic continuous peaks 16 and troughs 17 enhances the travel of the iron ore on the screen 10, thereby increasing the fineness of the iron ore screening. The noise generated during screening is absorbed by the sound-absorbing plate 8. The concentrate after screening by the screen 10 is temporarily stored in the concentrate collection hopper 9, and the coarse ore left on the surface of the screen 10 is temporarily stored in the coarse ore collection hopper 12, thus completing the iron ore beneficiation.
