However, there are certain problems in the sorting. If a large amount of raw materials are directly sent in, there will be serious accumulation of the raw materials, and the raw materials in the upper layer cannot receive the magnetic force, which will cause the iron ore in the upper layer to be sent out along with the phosphate ore, affecting the ore dressing quality. Utility Model Content

However, there are certain problems in the sorting. If a large amount of raw materials are directly sent in, the raw materials will have a serious accumulation phenomenon, and the raw materials in the upper layer cannot receive the magnetic force, which will cause the iron ore in the upper layer to be sent out along with the phosphate ore, affecting the ore dressing quality. A device for iron extraction and dephosphorization of high-phosphorus difficult-to-select iron ore is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-phosphorus refractory iron ore iron extraction and dephosphorization beneficiation device, comprising: a box body, the top of the box body is fixedly connected to a feeding pipe, and the bottom of the feeding pipe is fixedly connected to a feeding hopper; a feeding assembly, the feeding assembly is fixedly connected to the inner surface of the box body, the feeding assembly includes two groups of first springs, a feeding guide plate is fixedly connected between the end surfaces of the two groups of the first springs, and a first vibration motor is fixedly connected to the bottom of the feeding guide plate; a sorting assembly, the sorting assembly is fixedly connected to the inner surface of the box body, the sorting assembly includes two groups of second springs, and a sorting frame is fixedly connected between the end surfaces of the two groups of the second springs.

[0013] 1. In the utility model, when the high-phosphorus difficult-to-select iron ore is subjected to iron extraction and dephosphorization treatment, the raw materials will slide along the discharge hopper to the surface of the discharge guide plate.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a high-phosphorus refractory iron ore iron extraction and dephosphorization beneficiation device, comprising: a box body 1, a feeding pipe 2 is fixedly connected to the top of the box body 1, and a feeding hopper 7 is fixedly connected to the bottom of the feeding pipe 2; a feeding assembly 3, the feeding assembly 3 is fixedly connected to the inner surface of the box body 1, the feeding assembly 3 includes two groups of first springs 301, a feeding guide plate 302 is fixedly connected between the end surfaces of the two groups of first springs 301, and a first vibration motor 303 is fixedly connected to the bottom of the feeding guide plate 302; a sorting assembly 4, the sorting assembly 4 is fixedly connected to the inner surface of the box body 1, the sorting assembly 4 includes two groups of second springs 401, and a sorting motor 303 is fixedly connected between the end surfaces of the two groups of second springs 401. A selection rack 402, a side groove 5 is provided on the outer surface of the box body 1, the sorting rack 402 is located at the inner side of the side groove 5, the unloading guide plate 302 is equal to the width of the sorting rack 402, the unloading guide plate 302 is located at the upper side of the sorting rack 402, the top of the unloading guide plate 302 is fixedly connected to a top plate 304, the top of the top plate 304 is threadedly connected with a bolt 305, the lower end surface of the bolt 305 is rotatably connected to a baffle plate 306, the top of the baffle plate 306 is symmetrically fixedly connected to a limit rod 307, the limit rod 307 and the top plate 304 slide through, the bottom of the sorting rack 402 is fixedly connected to an electric-controlled magnetic suction plate 404, and the top of the sorting rack 402 is fixedly connected to a second vibration motor 403.

[0023] The effect achieved by the entire embodiment 1 is that, when the high-phosphorus refractory iron ore is subjected to iron extraction and dephosphorization treatment, the iron ore raw material is poured into the interior of the box body 1 from the feeding pipe 2, and the raw material will slide along the feeding hopper 7 to the surface of the feeding guide plate 302. At this time, starting the first vibration motor 303 can drive the feeding guide plate 302 to vibrate. Under the vibration of the feeding guide plate 302, the raw material can slowly slide along the inclined surface of the feeding guide plate 302, and the raw material sliding down from the feeding guide plate 302 can fall to the surface of the sorting rack 402 for sorting. When the raw material passes through the position of the feeding guide plate 302, the setting of the baffle 306 can limit the flow of the raw material. Since the baffle 306 is located above the inner bottom of the feeding guide plate 302 and maintains a certain distance, the raw material can only be sent out from between the feeding guide plate 302 and the baffle 306. The distance between plate 306 and the feed guide plate 302 is kept slightly larger than the size of the raw materials, so the raw materials can only be sent to the sorting rack 402 in a uniform and flat state. According to the size of different raw materials, turning the bolt 305 can drive the baffle 306 to move and adjust the use position. When the raw materials pass through the feed guide plate 302 and fall to the surface of the sorting rack 402, the feed guide plate 302 vibrates the raw materials uniformly, and the baffle 306 limits the flow of the raw materials and keeps them in a flat state, so the raw materials that slide to the surface of the sorting rack 402 can also be kept in a uniform and flat state. All raw materials can evenly contact the electric-controlled magnetic suction plate 404 at the bottom, effectively avoiding the problem of raw material accumulation and ineffective sorting, thereby improving the ore dressing quality. The iron and phosphorus in the raw materials are sorted by using the electric-controlled magnetic suction plate 404, and the iron extraction and dephosphorization treatment of the iron ore is completed.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a first cover plate 6 is hinged on the top of the discharge pipe 2, and a second cover plate 8 is hinged on the top of the box body 1.

[0025] The effect achieved by the entire embodiment 2 is that, through the coordinated use of the first cover plate 6 and the second cover plate 8, it can provide shielding for the top opening positions of the unloading pipe 2 and the box body 1 respectively, thereby preventing dust generated by the raw materials from floating in the working space during the sorting process.

[0026] Working principle: When the high-phosphorus refractory iron ore is subjected to iron extraction and dephosphorization treatment, the iron ore raw material is poured into the interior of the box body 1 from the discharge pipe 2, and the raw material will slide along the discharge hopper 7 to the surface of the discharge guide plate 302. At this time, starting the first vibration motor 303 can drive the discharge guide plate 302 to vibrate. Under the vibration of the discharge guide plate 302, the raw material can slowly slide along the inclined surface of the discharge guide plate 302, and the raw material sliding down from the discharge guide plate 302 can fall to the surface of the sorting rack 402 for sorting. When the raw material passes through the position of the discharge guide plate 302, the setting of the baffle 306 can limit the flow of the raw material. Since the baffle 306 is located above the inner bottom of the discharge guide plate 302 and maintains a certain distance, the raw material can only be sent out from between the discharge guide plate 302 and the baffle 306. The distance between the baffle 306 and the discharge guide plate 302 is kept slightly larger than the size of the raw material, so the raw material can only be kept evenly spread. The raw materials are sent to the position of the sorting rack 402 in a state. According to the size of different raw materials, the bolt 305 can be turned to drive the baffle 306 to move and adjust the use position. When the raw materials fall to the surface of the sorting rack 402 through the feeding guide plate 302, the feeding guide plate 302 vibrates the raw materials evenly, and the baffle 306 limits the flow of the raw materials and keeps them in a flat state, so the raw materials that slide to the surface of the sorting rack 402 can also be kept in a uniform and flat state. All raw materials can evenly contact the electric-controlled magnetic suction plate 404 at the bottom, effectively avoiding the problem of raw material accumulation and ineffective sorting, thereby improving the ore dressing quality. The iron and phosphorus in the raw materials are sorted by using the electric-controlled magnetic suction plate 404, and the iron extraction and dephosphorization treatment of the iron ore is completed. The first cover plate 6 and the second cover plate 8 are used in combination to provide shielding for the top opening position of the feeding pipe 2 and the box body 1, respectively, to avoid dust generated by the raw materials during the sorting process and floating in the working space.

[0027] The wiring diagram of the first vibration motor 303, the second vibration motor 403 and the electrically controlled magnetic attraction plate 404 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the first vibration motor 303, the second vibration motor 403 and the electrically controlled magnetic attraction plate 404 are no longer explained in detail.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
