Description

Technical Field

[0001] This utility model relates to the field of iron concentrate raw material pretreatment technology, specifically to a raw material pretreatment device for iron concentrate production. Background Technology

[0002] In the processing of iron concentrate, magnetite needs to be crushed first. The crushed material then needs to be pre-treated by screening to separate the ore powder that meets the processing specifications for further processing, while the non-compliant powder is re-crushed. Therefore, screening equipment is required to pre-treat the raw ore during the production process.

[0003] According to the patent application published on the Internet, "Pre-treatment equipment for raw materials in iron concentrate production (authorization announcement number: CN221288673U)," this utility model relates to the technical field of iron concentrate production equipment and discloses a pre-treatment equipment for raw materials in iron concentrate production, including: a base, with springs fixedly connected to all four sides of the upper surface of the base, and a screening box fixedly connected to the other end of the springs. This utility model, by setting up a fixed screen, a movable screen, a sliding column, a pulling block, and a rotating rod, when the No. 1 motor is running, the round shaft and the rotating rod will begin to rotate. At this time, the rotating rod will pull the pulling block to move to the right under the limit of the limiting groove. The inner surface of the pulling block will also pull the sliding column, causing the sliding column to begin moving to the right along the inner surface of the sliding groove. During this process, the connecting block will simultaneously drive the movable screen to move to the right as a whole. At this time, the overlapping area between the screen holes of the fixed screen and the movable screen gradually increases, which changes the size of the material that can pass through, thus achieving the function of adjusting the screening size.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In its use, this utility model employs a combination of a fixed screen and a movable screen to screen ore. However, in actual use, the movable screen slides and adjusts on the fixed screen, but can only adjust the size of one side of the screen hole, while the other side cannot be adjusted, resulting in incomplete screening. Furthermore, during discharge, the two types of ore are discharged from the same outlet, making it difficult to distinguish them at the discharge point. Therefore, it is necessary to improve the raw material pretreatment equipment for iron concentrate production to solve the above problems. Utility Model Content

[0032] Furthermore, the top of the sliding frame 312 has two grooves, and the sieve plate 314 and the pressure plate 315 are embedded in the grooves from bottom to top, so that the sieve plate 314 and the pressure plate 315 can be installed in the sliding frame 312.

[0033] Furthermore, discharge ports are provided on the left and right sides of the screening box 1. The screen plate 314 and the feed plate 311 are inclined in opposite directions, and the feed plate 311 is located below the screen plate 314.

[0034] Furthermore, the vibration assembly 32 includes a limiting baffle 321, which is fixedly installed on the front and rear sides of the sliding frame 312. A sliding block 322 is fixedly installed on the side of the limiting baffle 321 away from the sliding frame 312. A fixing block 323 is fixedly installed on the front and back of the screening box 1. A return spring 324 is fixedly installed between the fixing block 323 and the sliding block 322. A drive motor 325 is fixedly installed on the front and back of the screening box 1. A cam 326 is fixedly installed at the output end of the drive motor 325 to facilitate the screen plate 314 to vibrate back and forth for screening pretreatment of the ore.

[0035] Furthermore, six sliding blocks 322 are provided, and they are arranged in an array with three in the center of the right side of the screening box 1. The middle sliding block 322 is in contact with the cam 326, which makes it easier for the cam 326 to drive the sliding block 322 to slide.

[0036] Example 2:

[0037] To achieve centralized ore feeding and simultaneous disassembly of the top cover 41, this utility model provides another embodiment, please refer to [reference needed]. Figure 5Furthermore, in conjunction with Embodiment 1, the centralized feeding mechanism 4 includes a top cover 41, which is movably installed on the top of the screening box 1. A feed hopper 42 is fixedly installed on the top left side of the top cover 41. A connecting frame 43 is fixedly installed on both the front and back of the screening box 1. A mounting bracket 44 is fixedly installed on both the front and back of the top cover 41. A handle 45 is slidably installed inside the mounting bracket 44. A sliding plate 46 is fixedly installed on the inner side of the handle 45. A plug rod 47 is fixedly installed on the inner side of the sliding plate 46. A fixing spring 48 is fixedly installed between the outer side of the sliding plate 46 and the inner wall of the mounting bracket 44, which facilitates centralized feeding and allows for the disassembly of the top cover 41.

[0038] Furthermore, the connecting frame 43 and the corresponding position of the plug rod 47 are provided with insertion holes, and the plug rod 47 is inserted into the insertion hole. The connecting frame 43 and the corresponding position of the sliding plate 46 are provided with grooves, and the sliding plate 46 is inserted into the grooves, so that the top cover 41 can be fixed on the screening box 1.

[0039] In actual operation, when this device is used, a screen plate 314 with a suitable aperture is installed in the groove of the sliding frame 312. Then, the pressure plate 315 is installed above the screen plate 314 and embedded in the groove of the sliding frame 312. Then, the fixing bolts 316 are tightened and fixed. Then, the handle 45 is pulled, so that the handle 45 drives the sliding plate 46 to slide outward, so that the sliding plate 46 drives the insertion rod 47 to slide outward, and the sliding plate 46 compresses the fixing spring 48. Then, the top cover 41 is installed on the top of the screening box 1. Then, the handle 45 is released, so that the fixing spring 48 drives the sliding plate 46 to slide inward, so that the insertion rod 47 on the sliding plate 46 is inserted into the insertion hole of the connecting frame 43, and the sliding plate 46 is inserted into the groove of the connecting frame 43.

[0040] By adding ore from the feed hopper 42, the ore falls onto the screen plate 314. The drive motor 325 drives the cam 326 to rotate, which in turn drives the sliding block 322 to slide. The sliding block 322, together with the reset spring 324 and the fixed block 323, drives the sliding frame 312 to move up and down, causing the screen plate 314 on the sliding frame 312 to move up and down. This allows the ore to be screened on the screen plate 314. Ore that can pass through the screen plate 314 falls onto the discharge plate 311 and is discharged from the left side. Ore that cannot pass through the screen plate 314 moves to the right and is discharged from the right side of the screening box 1.
