Description

Technical Field

[0001] This utility model relates to the field of iron concentrate production technology, specifically to a high-efficiency iron concentrate magnetic separator. Background Technology

[0002] Iron concentrate is the main raw material, which is made from iron ore through crushing, beneficiation and other processing. The fluctuation of iron content will directly affect the quality of the finished pellets. During the production and processing of iron concentrate, since the production and processing are generally carried out by machinery, the iron concentrate will contain certain impurities. Therefore, before packaging and sales, it is necessary to screen it to remove the impurities inside the iron concentrate.

[0003] During the screening process of iron concentrate, impurities can easily clog the screen, leading to slow screening efficiency and affecting the subsequent production rate. Furthermore, after filtering out large particles of impurities, these particles tend to accumulate on the screen and, if not removed in time, can affect subsequent processing. Utility Model Content

[0004] To address the issues that impurities easily clog the screen during iron concentrate screening, leading to slow screening efficiency and impacting subsequent production rates, and that large particles tend to accumulate on the screen after being filtered out, affecting subsequent processing if not removed promptly, this invention aims to provide a high-efficiency iron concentrate magnetic separator.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a magnetic separator for iron concentrate with high beneficiation efficiency, comprising a device body, a feed hopper connected to the upper surface of the device body, and a screening component connected to the upper part of the feed hopper;

[0006] The screening assembly includes a chute located in the feed hopper. A rectangular slide plate slides within the chute. A spring is fixed between the inner surface of the chute and the rectangular slide plate. A drive motor is fixed to the side of the feed hopper. A connecting rod is located at the output end of the drive motor, penetrating the feed hopper. A half-gear is fixed to the other end of the connecting rod, meshing with an annular toothed plate. A rectangular movable rod is fixed to the side of the annular toothed plate. A sleeve is fixed to the inner surface of the feed hopper, and the rectangular movable rod movably penetrates the sleeve. A top rod is fixed to one side of one of the rectangular movable rods, with its upper end in contact with the lower surface of the rectangular slide plate. A connecting frame is fixed to the upper end of the rectangular slide plate, and a screening frame is installed within the connecting frame.

[0007] Preferably, the upper surface of the connecting frame is provided with a notch, and a protrusion is fixedly provided on one side of the screening frame. The protrusion is movably fitted with the inner surface of the notch, and a mounting bolt is threaded into the protrusion. The mounting bolt is threaded into the inside of the notch.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. This utility model can drive the connecting rod connected to the output end to rotate by starting the drive motor, which in turn drives the half-face gear to rotate. The top rod lifts the rectangular slide plate to move along the slide groove, so that the connecting frame can slide along the inner surface of the feed hopper. When the top rod is not in contact with the rectangular slide plate, the screening frame returns to its original position under the influence of the spring force, generating a certain vibration force to avoid the filtration efficiency being reduced by impurities. The filtered raw material falls into the device.

[0010] 2. After the utility model is used, the end of the device can be disengaged from the notch by rotating the mounting bolt. Then, the pull plate can be used to move the protrusion upward, thereby moving the screening frame upward and removing the screening frame from the feed hopper. This makes it convenient to pour out the impurities for centralized processing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-4 As shown, this utility model provides a high-efficiency iron concentrate magnetic separator, including a device body 1. The upper surface of the device body 1 is connected to a feed hopper 2. The device body 1 is a known technology, and its model is selected according to the actual use. It will not be described in detail here. The upper part of the feed hopper 2 is connected to a screening component 3.

[0019] The screening component 3 includes a chute 31, which is located in the feed hopper 2. A rectangular slide plate 32 slides within the chute 31. A spring 33 is fixed between the inner surface of the chute 31 and the rectangular slide plate 32. A drive motor 34 is fixed to the side of the feed hopper 2. A connecting rod 341 is located at the output end of the drive motor 34, penetrating the feed hopper 2. A half-face gear 342 is fixed to the other end of the connecting rod 341. The half-face gear 342 meshes with an annular toothed plate 343. A rectangular movable rod 35 is fixed to the side of the annular toothed plate 343. A sleeve 344 is fixed to the inner surface of the feed hopper 2. The rectangular movable rod 35 moves through the sleeve 344 and slides along the inner surface of the sleeve 344. The rectangular slide plate 32 has an "L" shaped cross-section for easy fixing of the connecting frame 37. A top rod 36 is fixed to one side of one of the rectangular movable rods 35. The upper end of the top rod 36 is in contact with the lower surface of the rectangular slide plate 32. The upper end of the rectangular slide plate 32 is fixedly provided with a connecting frame 37. A screening frame 38 is installed in the connecting frame 37. A filter screen is provided in the screening frame 38. Screening is performed through the filter screen in the screening frame 38. In order to avoid impurities clogging the mesh, the drive motor 34 can be started to drive the connecting rod 341 connected to the output end to rotate, which can drive the half-face gear 342 to rotate. The half-face gear 342 drives the ring tooth plate 343 that meshes with it to move back and forth along the sleeve 344. Thus, the top rod 36 lifts the rectangular slide plate 32 to move along the slide groove 31, so that the connecting frame 37 can slide along the inner surface of the feed hopper 2. The spring 33 is stretched. When the top rod 36 is not in contact with the rectangular slide plate 32, the screening frame 38 returns to its original position under the influence of the spring 33 force, generating a certain vibration force to avoid the impact of impurities and reduce the filtration efficiency. The filtered raw material falls into the device.

[0020] A protective shell 39 is fixedly provided on the side of the feed hopper 2. The drive motor 34 is located inside the protective shell 39 to protect the drive motor 34. Four springs 33 are provided and the springs 33 are arrayed between the inner surface of the slide groove 31 and the rectangular slide plate 32 to improve the rebound force and improve the filtration effect. Two sleeves 344 are provided and the sleeves 344 are symmetrically arranged on the inner surface of the feed hopper 2 to assist the movement of the rectangular movable rod 35.

[0021] The upper surface of the connecting frame 37 has a notch 4. A protrusion 41 is fixedly provided on one side of the screening frame 38. The protrusion 41 is movably fitted with the inner surface of the notch 4. A mounting bolt 43 is threaded into the protrusion 41. The mounting bolt 43 is threaded into the inside of the notch 4. A threaded groove for use with the mounting bolt 43 is provided in the notch 4. A pull plate 42 is fixedly provided on the upper surface of the protrusion 41. The cross-sectional shape of the pull plate 42 is an inverted "U" shape, which facilitates pulling the protrusion 41 to move upward. After use, the end of the mounting bolt 43 can be disengaged from the notch 4 by rotating it. Then, the protrusion 41 can be moved upward by the pull plate 42, which in turn moves the screening frame 38 upward, and the screening frame 38 can be taken out from the feed hopper 2 for easy pouring out of impurities for centralized processing.

[0022] Working principle: When using this utility model, raw materials are poured into the feed hopper 2 and filtered through the filter screen in the screening frame 38. To prevent impurities from clogging the screen, the drive motor 34 is started to drive the connecting rod 341 connected to the output end to rotate, which in turn drives the half-face gear 342 to rotate. The half-face gear 342 drives the annular toothed plate 343 that meshes with it to move back and forth along the sleeve 344, thereby pushing the rectangular slide plate 32 along the slide groove 31 through the top rod 36. This allows the connecting frame 37 to slide along the inner surface of the feed hopper 2, and the spring 33 is stretched. When the top rod 36 is not in contact with the rectangular slide plate 32, the screening frame 38 returns to its original position under the influence of the spring 33 force, generating a certain vibration force to avoid the filtration efficiency being reduced by impurities. The filtered raw materials fall into the device.

[0023] After use, the end of the screen can be disengaged from the notch 4 by rotating the mounting bolt 43. Then, the protrusion 41 can be moved upward by the pull plate 42, which in turn moves the screen frame 38 upward. The screen frame 38 can be removed from the feed hopper 2, making it easier to pour out the impurities for centralized processing.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
