DETAILED DESCRIPTION
[0028] 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.
[0029] Please see Figures 1-6 This utility model provides a technical solution: an iron ore screening device for preventing overflow, including a base 1, a rotating rod 2, an eccentric wheel 3, a fixed plate 4, a support frame 5, a fixed block 6, a first spring 7, a baffle body 8, a threaded rod 9, a fixed column 10, a first motor 11, a screen plate body 12, a connecting plate 13, an insert rod 14, a second spring 15, and a rotating block 16;
[0030] Example 1: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 Existing iron ore screening devices are not convenient for multi-layer screening of iron ore. Therefore, when it is necessary to classify and store iron ore by particle size, it may not be possible to make the particle size distribution more uniform. In order to solve this technical problem, the following technical content is disclosed in this embodiment.
[0031] An iron ore screening device for preventing spillage includes a base 1. Rotating rods 2 are rotatably connected to the front and rear ends of the base 1. An eccentric wheel 3 is fixedly connected to the outer side of the rotating rod 2. A fixing plate 4 is tightly attached to the left end of the eccentric wheel 3. A support frame 5 is fixedly connected to the inner side of the fixing plate 4. A fixing block 6 is fixedly connected to the outer side of the support frame 5. A first spring 7 is fixedly connected to the right end of the fixing block 6. The right end of the first spring 7 is fixedly connected to the base 1. The outer side of the fixing block 6 is slidably connected to the inside of the base 1.
[0032] When iron ore needs to be screened, the electric motor fixedly connected to the rear end of the rotating rod 2 is started, causing the rotating rod 2 to rotate. This drives the eccentric wheel 3 fixedly connected to the outer side of the rotating rod 2 to rotate. When the protruding part of the outer side of the eccentric wheel 3 is tightly fitted with the fixed plate 4, it drives the three support frames 5 arranged in an array on the inner side of the fixed plate 4 to move to the left at the same time. At this time, the fixed block 6 fixedly connected to the outer side of the support frame 5 moves to the left at the same time. The first spring 7 fixedly connected to the right end of the fixed block 6 is under pressure and deforms, causing the fixed block 6 to slide to the left inside the base 1. When the flat part of the outer side of the eccentric wheel 3 is tightly fitted with the fixed plate 4, it drives the three support frames 5 arranged in an array on the inner side of the fixed plate 4 to move to the right at the same time. At this time, the fixed block 6 fixedly connected to the outer side of the support frame 5 moves to the right at the same time. The first spring 7 fixedly connected to the right end of the fixed block 6 loses pressure and restores its elasticity, causing the fixed block 6 to slide to the right inside the base 1. This can simultaneously drive the multi-layer screen to screen, making the iron ore particle size distribution more uniform.
[0033] Example 2: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 Existing iron ore screening devices are not convenient to prevent iron ore leakage during the screening process, which can easily lead to iron ore overflow when there is a large amount of ore. In order to solve this technical problem, this embodiment discloses the following technical content.
[0034] An iron ore screening device for preventing spillage includes a support frame 5. The right end of the support frame 5 is rotatably connected to a right threaded rod 9, and the outer side of the threaded rod 9 is threadedly connected to a right baffle body 8. The front and rear ends of the baffle body 8 are slotted and connected to the inside of the support frame 5. The right end of the baffle body 8 is slidably connected to the outer side of a fixed column 10, and the upper and lower ends of the fixed column 10 are fixedly connected to the support frame 5. The upper end of the threaded rod 9 is fixedly connected to a first motor 11.
[0035] When it is necessary to prevent iron ore from overflowing during screening, the first motor 11 is started, which drives the threaded rod 9 fixedly connected to the lower end of the first motor 11. This causes the baffle body 8, which is threadedly connected to the outer side of the threaded rod 9, to move upward. At this time, the baffle body 8 slides upward on the outside of the fixed column 10. The height of the baffle body 8 moving upward is adjusted according to the amount of iron ore to be screened. At the same time, the front and rear ends of the baffle body 8 move upward inside the support frame 5, which can prevent iron ore from overflowing during the screening process.
[0036] Example 3: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4Existing iron ore screening devices are not convenient for disassembling and replacing screens, which can easily lead to screen damage after prolonged use, affecting the iron ore screening process. To solve this technical problem, this embodiment discloses the following technical content.
[0037] An iron ore screening device for preventing spillage includes a support frame 5. A connecting plate 13 is connected to the internal slot of the support frame 5. The lower end of the connecting plate 13 is fixedly connected to the screen plate body 12. The upper end of the connecting plate 13 is connected to the internal slot of the insert rod 14. The inner end of the insert rod 14 is connected to the support frame 5 through the external slot. The inner side of the insert rod 14 is fixedly connected to the second spring 15. The inner side of the second spring 15 is fixedly connected to the rotating block 16. The inner side of the rotating block 16 is rotatably connected to the inside of the support frame 5.
[0038] When the screen needs to be replaced, pull the insert rod 14 outward. At this time, the second spring 15 fixedly connected to the inner side of the insert rod 14 is under pressure and deforms, causing the inner side of the lower end of the insert rod 14 to disengage from the slot connection between the connecting plate 13 and the support frame 5. Rotate the connecting plate 13, causing the rotating block 16 to rotate inside the support frame 5. At this time, the outer side of the connecting plate 13 is no longer obstructed. Pull the connecting plate 13 connected to the slot inside the support frame 5 outward, driving the screen plate body 12 to move outward, and disassembling the damaged screen plate body 12. Push the new connecting plate 13 inward, so that the connecting plate 13 and the screen plate body 12 move inward at the same time, and drive the connecting plate 13 to move inside the support frame 5, and connect with the support frame 5 through a slot. Rotate the rotating block 16 back to its original position and release the insert rod 14. At this time, the second spring 15 fixedly connected to the inner side of the insert rod 14 loses pressure and restores its elasticity, so that the insert rod 14 and the connecting plate 13 are connected through a slot, and the connecting plate 13 is limited. This can prevent the screen from being damaged during iron ore screening, which would affect the screening fineness.
