Description

Technical Field

[0001] This utility model relates to the field of iron sand screening technology, specifically to a screening device for iron sand preparation. Background Technology

[0002] Screening devices play a crucial role in the iron sand preparation process. Their primary purpose is to precisely classify the raw iron sand to ensure the quality and performance of the final product. This device effectively separates iron sand particles of different sizes through vibration or rotation, ensuring that each grade of iron sand meets specific particle size requirements. This not only helps improve the utilization rate of iron sand but also reduces energy consumption and costs in subsequent processing.

[0003] However, existing iron sand screening devices have relatively limited functionality and cannot remove all impurities from the iron sand during screening. This results in impurities potentially being mixed into the iron sand at each grade after screening, leading to an uneven purity of the iron sand.

[0004] However, existing iron sand screening devices have certain functional limitations. The main limitation is that the screening process often cannot effectively remove all impurities from the iron sand at the same time. This defect means that iron sand of different grades may still contain different types of impurities after screening, which affects the purity and quality of the iron sand. In order to improve the purity of iron sand, additional impurity removal steps are usually required, which not only increases production costs but may also reduce production efficiency. Therefore, a screening device for iron sand preparation is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing iron sand screening devices often cannot effectively remove all impurities from iron sand at the same time. This invention provides a screening device for iron sand preparation.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A screening device for iron sand preparation includes a screening box, a screen fixedly installed inside the screening box, a notch on the left wall of the screening box, a suction roller movably installed inside the notch, a servo motor for driving the suction roller to rotate fixedly installed on the rear wall of the screening box, a scraper fixedly installed inside the screening box, a removal box fixedly installed on the left side of the screening box, the right wall and bottom of the removal box being hollowed out, an arc-shaped plate inside the removal box, a drive assembly for driving the arc-shaped plate to rise, fall and tilt inside the removal box, a discharge hopper fixedly installed at the bottom of the removal box, four buffer legs fixedly installed on the outer wall of the discharge hopper, two buffer legs fixedly installed at the bottom of the screening box, two vibrating motors fixedly installed on the front wall of the screening box, and a guide assembly for guiding iron sand provided at the end of the screen away from the removal box.

[0008] Furthermore, the drive assembly includes square plates. Two square plates are fixedly installed on the inner left wall of the impurity removal box. A rotatable lead screw is movably installed between the two square plates. An actuator motor for driving the lead screw to rotate is fixedly installed on the top of the upper square plate. An L-shaped rod is threaded onto the lead screw. A sliding groove is opened on the inner left wall of the impurity removal box. A slider is movably installed inside the sliding groove. The slider and the L-shaped rod are fixedly connected. An arc-shaped plate is rotatably installed on the vertical end of the L-shaped rod.

[0009] Furthermore, the drive assembly also includes a groove, with a groove opened at the top of the vertical end of the L-shaped rod, a rotating shaft being movably installed inside the groove, and an actuator motor for driving the rotating shaft to rotate being fixedly installed on the side wall of the L-shaped rod, and an arc plate being fixedly connected to the rotating shaft.

[0010] Furthermore, the material guiding assembly includes a material guiding plate, with the end of the screen away from the impurity removal box fixedly installed with the material guiding plate, and two side plates distributed in a mirror image fixedly installed on the top of the material guiding plate. Electric telescopic rods are fixedly installed on the front and rear walls inside the screening box, and a connecting plate is fixedly installed at the output end of each electric telescopic rod. A material guiding trough is fixedly installed between the two connecting plates.

[0011] Furthermore, the material guiding assembly also includes convex grooves. Two convex grooves are opened at the bottom of the material guiding plate. A convex rod is fixedly installed inside each convex groove, and each convex rod is fixedly connected to the material guiding groove.

[0012] Furthermore, the scraper has a triangular cross-section, and the top of the scraper is inclined downwards from left to right.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model first feeds iron sand to be screened into the impurity removal box, causing the iron sand to accumulate on top of the arc-shaped plate. Then, the servo motor is started, driving the suction roller to rotate clockwise. During the rotation, the arc-shaped plate first attracts the iron sand accumulated on top of the plate, which is then scraped off by the scraper. To ensure that the arc-shaped plate can effectively attract the iron sand during rotation, the drive assembly can control the arc-shaped plate to gradually move upward according to the iron sand screening progress, so that the iron sand on top of the arc-shaped plate can always maintain a distance that can be attracted by the suction roller. Because the arc-shaped plate is arc-shaped, the iron sand accumulated on top of the arc-shaped plate will also converge as it gradually decreases, thus facilitating the suction roller to attract the iron sand. When all the iron sand on top of the arc-shaped plate has been attracted by the suction roller, it is transported to the screening box. After the material is placed inside the screen, the remaining impurities will be placed on top of the arc plate. At this time, the control drive component will rotate the arc plate at a certain angle to make the impurities fall and be discharged from the discharge funnel. After the iron sand is scraped off by the scraper, it will fall onto the surface of the screen. The iron sand on the screen surface will roll from high to low. Smaller iron sand will fall to the bottom of the screening box and continue to roll down. Larger iron sand will roll from high to low on the screen surface. The function of the guide component is to stagger the iron sand discharge position, so that the iron sand on the screen surface and the iron sand on the bottom of the screening box are staggered, thus facilitating the collection of iron sand of different sizes. To avoid the accumulation of iron sand on the screen surface or the bottom of the screening box, two vibrating motors can be started at the same time. Attached Figure Description

[0025] like Figures 1 to 5As shown, a screening device for iron sand preparation includes a screening box 1, a screen 2 fixedly installed inside the screening box 1, a notch 3 on the left wall of the screening box 1, a suction roller 4 movably installed inside the notch 3, a servo motor 5 for driving the suction roller 4 to rotate fixedly installed on the rear wall of the screening box 1, a scraper 6 fixedly installed inside the screening box 1, a removal box 7 fixedly installed on the left side of the screening box 1, the right wall and bottom of the removal box 7 being hollowed out, an arc-shaped plate 8 inside the removal box 7, a drive assembly 9 for driving the arc-shaped plate 8 to rise, fall and tilt inside the removal box 7, and a discharge funnel fixedly installed at the bottom of the removal box 7. 10. Four buffer legs 11 are fixedly installed on the outer wall of the discharge hopper 10. Two buffer legs 11 are fixedly installed on the bottom of the screening box 1. Two vibrating motors 12 are fixedly installed on the front wall of the screening box 1. A guide assembly 13 for guiding iron sand is provided at the end of the screen 2 away from the impurity removal box 7. It should be noted that, firstly, the iron sand to be screened is put into the interior of the impurity removal box 7, so that the iron sand accumulates on the top of the arc plate 8. Then, the servo motor 5 is started, which drives the suction roller 4 to rotate clockwise. During the rotation of the arc plate 8, the iron sand accumulated on the top of the arc plate 8 is first sucked up and then scraped off by the scraper 6. In order to ensure During rotation, the arc-shaped plate 8 can effectively adsorb iron sand. The drive component 9 can control the arc-shaped plate 8 to gradually move upward according to the iron sand screening progress, so that the iron sand at the top of the arc-shaped plate 8 can always maintain a distance that can be adsorbed by the suction roller 4. Because the arc-shaped plate 8 is arc-shaped, the iron sand accumulated at the top of the arc-shaped plate 8 will also converge as it gradually decreases, thus facilitating the adsorption of the iron sand by the suction roller 4. When all the iron sand at the top of the arc-shaped plate 8 has been adsorbed by the suction roller 4 and transported into the screening box 1, the remaining impurities will be on the top of the arc-shaped plate 8. At this time, controlling the drive component 9 to rotate the arc-shaped plate 8 at a certain angle will cause the impurities to fall off and exit from the discharge funnel 1. After the discharge is completed, the iron sand scraped off by the scraper 6 will fall onto the surface of the screen 2. The iron sand on the surface of the screen 2 will roll from high to low. Smaller iron sand will fall to the bottom of the screening box 1 and continue to roll downwards, while larger iron sand will roll from high to low on the surface of the screen 2. The function of the guide component 13 is to stagger the iron sand discharge position, so that the iron sand on the surface of the screen 2 and the iron sand on the bottom of the screening box 1 are staggered, thus facilitating the collection of iron sand of different sizes. To avoid the accumulation of iron sand on the surface of the screen 2 or the bottom of the screening box 1, two vibrating motors 12 can be started at the same time.

[0026] like Figures 1 to 3As shown, the drive assembly 9 includes a square plate 901. Two square plates 901 are fixedly installed on the inner left wall of the impurity removal box 7. A rotatable lead screw 903 is movably installed between the two square plates 901. An actuator motor 902 for driving the lead screw 903 to rotate is fixedly installed on the top of the upper square plate 901. An L-shaped rod 904 is threadedly connected to the lead screw 903. A sliding groove 905 is opened on the inner left wall of the impurity removal box 7. A slider 906 is movably installed inside the sliding groove 905. The slider 906 and the L-shaped rod 904 are fixedly connected. An arc plate 8 is rotatably installed on the vertical end of the L-shaped rod 904. It should be noted that after the actuator motor 902 is started, it can drive the lead screw 903 to rotate back and forth. The back and forth rotation of the lead screw 903 can cause the L-shaped rod 904 to rise and fall. The rising and falling of the L-shaped rod 904 can cause the slider 906 to slide inside the sliding groove 905. The rising and falling of the L-shaped rod 904 can cause the arc plate 8 to rise and fall synchronously.

[0027] like Figures 1 to 3 As shown, the drive assembly 9 also includes a groove 907. The top of the vertical end of the L-shaped rod 904 has a groove 907. A rotating shaft 908 is movably installed inside the groove 907. An actuator motor 909 for driving the rotating shaft 908 to rotate is fixedly installed on the side wall of the L-shaped rod 904. The arc plate 8 is fixedly connected to the rotating shaft 908. It should be noted that after the actuator motor 909 is started, it can drive the rotating shaft 908 to rotate at a preset angle and tilt angle. The rotation of the rotating shaft 908 will drive the arc plate 8 to rotate synchronously.

[0028] like Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the material guiding assembly 13 includes a material guiding plate 1301. The end of the screen 2 furthest from the impurity removal box 7 is fixedly equipped with the material guiding plate 1301. Two mirror-distributed side plates 1302 are fixedly installed on the top of the material guiding plate 1301. Electric telescopic rods 1303 are fixedly installed on both the front and rear walls inside the screening box 1. A connecting plate 1304 is fixedly installed at the output end of each electric telescopic rod 1303. A material guiding trough 1305 is fixedly installed between the two connecting plates 1304. [Further details needed] It should be noted that when the two electric telescopic rods 1303 are activated, they will drive the connecting plates 1304 connected to them to move. The two connecting plates 1304 can jointly drive the guide trough 1305 to move. The iron sand placed on the surface of the screen 2 will roll further down to the top of the guide plate 1301. The iron sand placed on the top of the guide plate 1301 will roll further down to the inside of the guide trough 1305. The iron sand placed inside the guide trough 1305 will roll further down to complete the discharge.

[0029] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the material guiding assembly 13 also includes a convex groove 1306. Two convex grooves 1306 are formed at the bottom of the material guiding plate 1301. A convex rod 1307 is fixedly installed inside each convex groove 1306. Each convex rod 1307 is fixedly connected to the material guiding groove 1305. It should be noted that after the material guiding groove 1305 moves, it can drive the convex rod 1307 to slide inside the corresponding convex groove 1306. The movement trajectory of the material guiding groove 1305 can be restricted by the cooperation of the convex groove 1306 and the convex rod 1307.

[0030] like Figure 2 As shown, the scraper 6 has a triangular cross-section, and the top of the scraper 6 is set downwards from left to right. It should be noted that the downwards tilt of the top of the scraper 6 from left to right can better guide the iron sand to fall onto the surface of the screen 2.

[0031] In summary:

[0032] First, the iron sand to be screened is fed into the impurity removal box 7, causing it to accumulate on top of the arc-shaped plate 8. Then, the servo motor 5 is started, driving the suction roller 4 to rotate clockwise. During the rotation, the arc-shaped plate 8 first attracts the iron sand accumulated on top, which is then scraped off by the scraper 6. To ensure that the arc-shaped plate 8 can effectively attract the iron sand during rotation, the drive component 9 controls the arc-shaped plate 8 to gradually move upward according to the iron sand screening progress, so that the iron sand on top of the arc-shaped plate 8 can always maintain a distance that can be attracted by the suction roller 4. Because the arc-shaped plate 8 is arc-shaped, the iron sand accumulated on top of the arc-shaped plate 8 will also converge as it gradually decreases, thus facilitating the suction roller 4 to attract the iron sand. When all the iron sand on top of the arc-shaped plate 8 has been attracted by the suction roller 4, it is transported into the screening box 1. Afterwards, the remaining impurities will be placed on top of the arc plate 8. At this time, the control drive component 9 will rotate the arc plate 8 at a certain angle so that the impurities will fall and be discharged from the discharge funnel 10. After the iron sand is scraped off by the scraper 6, it will fall onto the surface of the screen 2. The iron sand on the surface of the screen 2 will roll from high to low. The smaller iron sand will fall to the bottom of the screening box 1 and continue to roll down. The larger iron sand will roll from high to low on the surface of the screen 2. The function of the guide component 13 is to stagger the iron sand discharge position, so that the iron sand on the surface of the screen 2 and the iron sand on the bottom of the screening box 1 are staggered, thus facilitating the collection of iron sand of different sizes. In order to avoid the iron sand from accumulating on the surface of the screen 2 or the bottom of the screening box 1, two vibration motors 12 can be started at the same time.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
