Description

Technical Field

[0001] This invention relates to the field of magnetic sorting technology, and in particular to a magnetic sorting and conveying mechanism and its conveying method. Background Technology

[0002] Magnetic sorting and conveying equipment is typically used to separate mixtures or materials containing metallic substances using magnetic force. It mainly consists of a magnetic sorting system and a conveying system, and is commonly used in industries such as mining, recycling, and metallurgy.

[0003] Existing technologies, such as the invention with publication number CN107159433B, disclose a centralized separation system for dry screening of magnetic ore. This patent employs a set of mobile conveyor belts I for feeding medium-crushed ore bins, a set of medium-crushed ore bins, a set of medium-crushed ore feed belts II, and a set of medium crushers. The key feature is that a medium-crushed ore discharge belt is located below the medium crushers, connected to the feeding end of a mobile conveyor belt III with a discharge trolley. Below the mobile conveyor belt III with the discharge trolley is a set of combined dry screening and pre-selection bins. Dry ore separators are correspondingly located below the combined dry screening and pre-selection bins, and a dry grading vibrating screen is correspondingly located below each dry ore separator. The advantages of this invention are: a compact system layout, maximum removal of waste ore before grinding, improved feed grade, energy saving and consumption reduction in the concentrator, and lower concentrator costs. The inventors discovered in daily use that traditional magnetic sorting and conveying mechanisms often lack effective limiting for substandard items in practical applications. When materials are conveyed and initially sorted on the first magnetic separator conveyor belt, due to factors such as vibration generated by the conveyor belt operation and the irregular shape of the materials themselves, substandard items are prone to lateral displacement during the conveying process, or even fall off the edge of the conveyor belt, resulting in decreased sorting accuracy and increased material loss. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to propose a magnetic sorting and conveying mechanism and its conveying method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic sorting and conveying mechanism and its conveying method, comprising a support and a limiting structure. A first magnetic separation conveyor belt is installed at the upper end of the support, a connecting frame is installed at one end of the support, a second magnetic separation conveyor belt is installed at the upper end of the connecting frame, and a limiting structure is provided at the upper end of the support. The limiting structure includes two fixed rods, both of which are fixedly connected to the support. A slide rail is fixedly connected to the upper end of the fixed rods. Two sliders are slidably connected to the inner wall of the slide rail. A connecting plate is fixedly connected to the upper surface of the sliders. A follower plate is fixedly connected to one side of the connecting plate. Two fixed plates are fixedly connected to the side of the slide rail near the follower plate. A screw is rotatably connected to the inner wall of the fixed plate, and the screw is threadedly connected to the follower plate. A connecting rod is fixedly connected to the lower surface of the sliders, and a limiting plate is fixedly connected to the lower end of the connecting rod.

[0006] By adopting this preferred solution, when it is necessary to limit the secondary selection item, rotating the screw causes the follower plate to move, which in turn causes the connecting plate to move. The connecting plate then causes the slider to slide on the inner wall of the slide rail, which in turn causes the connecting rod to move. The connecting rod then causes the limiting plate to move, thereby adjusting the distance between the two limiting plates. This allows the limiting plates to effectively limit the secondary selection item, preventing it from shifting or falling during transport. This ensures that the secondary selection item can accurately enter the next process, improving the stability and continuity of the magnetic separation operation.

[0007] Preferably, a protective pad, which is a rubber pad, is fixedly connected to one side of each of the two limiting plates that are close to each other.

[0008] By adopting this preferred solution, the protective pad can protect the magnetically separated items and prevent the limiting plate from causing wear and tear on the magnetically separated items.

[0009] Preferably, a limiting rod is fixedly connected inside the slide rail, and the limiting rod is slidably connected to the slider.

[0010] By adopting this preferred solution, the limiting rod can limit the slider, preventing the slider from deviating when sliding on the inner wall of the slide rail, thus improving the stability of the slider sliding.

[0011] Preferably, a rotating plate is fixedly connected to one end of the screw, and the cross-section of the rotating plate is quincunx-shaped.

[0012] By adopting this preferred solution, the rotating plate can be directly rotated when the screw needs to be rotated, and the rotating plate drives the screw to rotate, making it more convenient to rotate the screw.

[0013] Preferably, the bracket has an internal collection structure, which includes two mounting rods. Both mounting rods are fixedly connected to the bracket. A connecting frame is slidably connected to the surface of the mounting rod. A lead screw is threaded to the inner wall of the connecting frame and abuts against the mounting rod. A connecting block is fixedly connected to the side of the two connecting frames that are close to each other. A collection box is fixedly connected to the side of the two connecting blocks that are close to each other.

[0014] By adopting this preferred solution, when it is necessary to collect the items sorted by the first magnetic separation conveyor belt, the connecting frame is slid along the mounting rod to a suitable position, and the screw is tightened to make it tightly abut against the mounting rod. This securely fixes the connecting frame and the collection box below the discharge end of the first magnetic separation conveyor belt, achieving accurate receiving and collection of the sorted items. This effectively avoids items scattering and causing secondary pollution or resource waste. At the same time, the detachable design of the collection box facilitates subsequent cleaning and transfer operations.

[0015] Preferably, handles are fixedly connected to both sides of the collection box, and the handles have a "U" shaped cross-section.

[0016] By adopting this preferred solution, the handle can be pulled directly when the collection box needs to be moved, making it more convenient to pull the collection box.

[0017] Preferably, an auxiliary plate, which is a plastic plate, is fixedly connected to the end of the lead screw away from the collection box.

[0018] By adopting this preferred solution, the cost of plastic materials is relatively low, which greatly reduces the manufacturing cost of plastic materials.

[0019] Preferably, the support has a separation structure on both sides, which includes two connecting plates fixed to both sides of the support. An auxiliary rod is slidably connected to the inner wall of each connecting plate, and a connecting rod is fixedly connected to the lower end of each auxiliary rod. A scraper is fixedly connected to one end of each connecting rod that is close to the other. A threaded ring is rotatably connected to the upper surface of each connecting plate, and the threaded ring is threadedly connected to the auxiliary rod. This preferred solution achieves the following: when the scraper needs to be brought into contact with the first magnetic separation conveyor belt to separate items, the rotatable threaded ring drives the auxiliary rod to slide downwards along the inner wall of the connecting plate, causing the scraper to gradually approach and contact the surface of the first magnetic separation conveyor belt. This effectively scrapes off the magnetic material adsorbed on the conveyor belt, achieving precise separation of magnetic and non-magnetic materials, improving sorting efficiency and material recovery rate.

[0020] Preferably, the arc surface of the threaded ring has a plurality of slots, which are evenly distributed on the threaded ring. This preferred design increases the friction between the hand and the threaded ring, preventing slippage when rotating the threaded ring.

[0021] Preferably, in step S1, when it is necessary to limit the secondary item, the screw is rotated, the screw drives the follower plate to move, the follower plate drives the connecting plate to move, the connecting plate drives the slider to slide on the inner wall of the slide rail, the slider drives the connecting rod to move, and the connecting rod drives the limiting plate to move, thereby adjusting the distance between the two limiting plates so that the limiting plate can effectively limit the secondary item, prevent the secondary item from shifting or falling during the conveying process, and ensure that the secondary item can accurately enter the next process. S2. When it is necessary to collect the items sorted by the first magnetic separation conveyor belt, slide the connecting frame along the mounting rod to the appropriate position, and tighten the screw to make it closely abut against the mounting rod, thereby firmly fixing the connecting frame and the collection box below the discharge end of the first magnetic separation conveyor belt, so as to achieve accurate receiving and collection of the sorted items. S3. When it is necessary to separate the items by having the scraper adhere to the first magnetic separation conveyor belt, the threaded ring can be rotated to drive the auxiliary rod to slide down along the inner wall of the connecting plate, so that the scraper gradually approaches and adheres to the surface of the first magnetic separation conveyor belt, thereby effectively scraping off the magnetic material adsorbed on the conveyor belt.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by setting a limiting structure, the effect of flexibly adjusting the limiting position of the secondary selection items can be easily achieved. This solves the problem that traditional magnetic separators lack effective limiting means during the conveying process, which leads to the secondary selection items being prone to deviation, accumulation, or even falling, affecting the subsequent sorting accuracy and the continuity of the operation. This device realizes stepless adjustment of the distance between the two limiting plates through a screw transmission mechanism, which can adapt to magnetic separation items of different specifications and sizes, so that the limiting plates always maintain appropriate contact with the edge of the items, providing a reliable guiding effect and avoiding excessive squeezing that could damage the items.

[0023] 2. In this invention, by setting up a collection structure, the sorted items can be quickly located, collected, and conveniently transferred. This solves the problem that traditional magnetic separators lack a dedicated collection device at the discharge end, causing the sorted items to scatter directly on the ground, resulting in material mixing and secondary pollution, as well as requiring manual secondary cleaning and sorting, which greatly increases labor intensity and working time. This device, through the sliding cooperation design of the mounting rod and the connecting frame, allows the collection box to be flexibly adjusted along the longitudinal direction of the support. Combined with the screw locking mechanism, it can be quickly fixed and released to meet the collection needs under different working conditions. At the same time, the collection box adopts a detachable structure, which facilitates timely replacement of empty boxes after full load, ensuring continuous and efficient operation of magnetic separation.

[0024] 3. In this invention, by setting a separation structure, the magnetic materials can be easily and efficiently scraped and separated, and quickly cleaned and maintained. This solves the problems in traditional magnetic separators where magnetic materials are easily and firmly adsorbed on the surface of the conveyor belt and are difficult to detach on their own, resulting in non-magnetic materials being mixed into the magnetic materials and causing a decrease in the separation purity. It also solves the problems of time-consuming and laborious manual cleaning of residual materials on the surface of the conveyor belt, which affects the operating efficiency of the equipment.

[0027] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1, such as Figure 1-5 As shown, the present invention provides a magnetic sorting and conveying mechanism and its conveying method, including a support 1 and a limiting structure 5. A first magnetic separation conveyor belt 2 is installed at the upper end of the support 1, a connecting frame 3 is installed at one end of the support 1, a second magnetic separation conveyor belt 4 is installed at the upper end of the connecting frame 3, a limiting structure 5 is provided at the upper end of the support 1, a collection structure 6 is provided inside the support 1, and a separation structure 7 is provided on both sides of the support 1.

[0030] The following section will explain the specific settings and functions of its limiting structure 5, collecting structure 6, and separating structure 7.

[0031] like Figure 2 and Figure 3 As shown, the limiting structure 5 includes two fixed rods 503, both of which are fixedly connected to the bracket 1. The upper end of the fixed rod 503 is fixedly connected to a slide rail 501. The inner wall of the slide rail 501 is slidably connected to two sliders 509. The upper surface of the sliders 509 is fixedly connected to a connecting plate 507. One side of the connecting plate 507 is fixedly connected to a follower plate 511. The side of the slide rail 501 near the follower plate 511 is fixedly connected to two fixed plates 512. The inner wall of the fixed plate 512 is rotatably connected to a screw 506. The screw 506 is threadedly connected to the follower plate 511. The lower surface of the slider 509 is fixedly connected to a connecting rod 510. The lower end of the connecting rod 510 is fixedly connected to a limiting plate 502. When it is necessary to limit the selection of secondary items, the screw 506 is rotated. The screw 506 drives the follower plate 511 to move, the follower plate 511 drives the connecting plate 507 to move, the connecting plate 507 drives the slider 509 to slide on the inner wall of the slide rail 501, the slider 509 drives the connecting rod 510 to move, and the connecting rod 510 drives the limiting plate 502 to move, thereby adjusting the distance between the two limiting plates 502, so that the limiting plates 502 can effectively limit the secondary items, preventing the secondary items from deviating or falling during the conveying process, ensuring that the secondary items can accurately enter the next process, and improving the stability and continuity of the magnetic separation operation. Protective pads 504 are fixedly connected to the side of the two limiting plates 502 that are close to each other. The protective pads 504 are rubber pads. The protective pads 504 can protect the magnetically separated items and prevent the limiting plates 502 from causing wear to the magnetically separated items. A limiting rod 508 is fixedly connected inside the slide rail 501, and the limiting rod 508 is slidably connected to the slider 509. The limiting rod 508 can limit the slider 509, preventing it from deviating when sliding on the inner wall of the slide rail 501, thus improving the stability of the slider 509's sliding. A rotating plate 505 is fixedly connected to one end of the screw 506. The rotating plate 505 has a quincunx cross-section. When it is necessary to rotate the screw 506, the rotating plate 505 can be rotated directly, causing the screw 506 to rotate. The rotating plate 505 makes rotating the screw 506 more convenient.

[0032] like Figure 1 and Figure 4 As shown, the collection structure 6 includes two mounting rods 61, both of which are fixedly connected to the bracket 1. A connecting frame 63 is slidably connected to the surface of the mounting rods 61, and a threaded rod 65 is threadedly connected to the inner wall of the connecting frame 63. The threaded rod 65 abuts against the mounting rod 61. Connecting blocks 62 are fixedly connected to the sides of the two connecting frames 63 that are close to each other, and a collection box 66 is fixedly connected to the sides of the two connecting blocks 62 that are close to each other. When it is necessary to collect items sorted by the first magnetic separation conveyor belt 2, the connecting frame 63 is slid along the mounting rod 61 to a suitable position, and then the threaded rod 65 is tightened to make it tightly abut against the mounting rod 61. This securely fixes the connecting frame 63 and the collection box 66 below the discharge end of the first magnetic separation conveyor belt 2, achieving precise receiving and collection of sorted items, effectively preventing items from scattering and causing secondary pollution or resource waste. The detachable design of the collection box 66 facilitates subsequent cleaning and transfer operations. Handles 67 are fixedly connected to both sides of the collection box 66, and the cross-section of the handles 67 is U-shaped. When it is necessary to pull the collection box 66, the handle 67 can be pulled directly. The handle 67 moves the collection box 66, making it easier to pull. An auxiliary plate 64 is fixedly connected to the end of the lead screw 65 away from the collection box 66. The auxiliary plate 64 is made of plastic. Plastic is a relatively inexpensive material, which greatly reduces the manufacturing cost of plastic.

[0033] like Figure 1 and Figure 5 As shown, the separation structure 7 includes two connecting plates 73, which are fixed to both sides of the support 1. An auxiliary rod 72 is slidably connected to the inner wall of the connecting plate 73. A connecting rod 74 is fixedly connected to the lower end of the auxiliary rod 72. A scraper 71 is fixedly connected to one end of the two connecting rods 74 that are close to each other. A threaded ring 75 is rotatably connected to the upper surface of the connecting plate 73, and the threaded ring 75 is threadedly connected to the auxiliary rod 72. When it is necessary to press the scraper 71 against the first magnetic separation conveyor belt 2 to separate the items, the threaded ring 75 can be rotated to drive the auxiliary rod 72 to slide downwards along the inner wall of the connecting plate 73, causing the scraper 71 to gradually approach and adhere to the surface of the first magnetic separation conveyor belt 2, thereby effectively scraping off the magnetic material adsorbed on the conveyor belt, achieving precise separation of magnetic and non-magnetic materials, improving sorting efficiency and material recovery rate. The arc surface of the threaded ring 75 has several slots 76, which are evenly distributed on the threaded ring 75. The notch 76 increases the friction between the hand and the threaded ring 75, preventing slippage when rotating the threaded ring 75.

[0034] The overall working principle is as follows: when it is necessary to limit the secondary item, the screw 506 is rotated. The screw 506 drives the follower plate 511 to move, the follower plate 511 drives the connecting plate 507 to move, the connecting plate 507 drives the slider 509 to slide on the inner wall of the slide rail 501, the slider 509 drives the connecting rod 510 to move, and the connecting rod 510 drives the limiting plate 502 to move, thereby adjusting the distance between the two limiting plates 502, so that the limiting plates 502 can effectively limit the secondary item, preventing the secondary item from shifting or falling during the conveying process, and ensuring the safety of the secondary item. The selected items can accurately enter the next process, improving the stability and continuity of the magnetic separation operation. The protective pad 504 can protect the magnetically separated items and prevent the limiting plate 502 from causing wear to the magnetically separated items. The limiting rod 508 can limit the slider 509 and prevent the slider 509 from deviating when sliding on the inner wall of the slide rail 501, thus improving the sliding stability of the slider 509. When it is necessary to rotate the screw 506, the rotating plate 505 can be rotated directly, and the rotating plate 505 drives the screw 506 to rotate, making it more convenient to rotate the screw 506.

[0035] When it is necessary to collect the items sorted by the first magnetic separation conveyor belt 2, the connecting frame 63 is slid along the mounting rod 61 to a suitable position, and the screw 65 is tightened to make it tightly abut against the mounting rod 61, thereby firmly fixing the connecting frame 63 and the collection box 66 below the discharge end of the first magnetic separation conveyor belt 2, realizing accurate receiving and collection of sorted items, effectively avoiding secondary pollution or resource waste caused by the scattering of items. At the same time, the detachable design of the collection box 66 facilitates subsequent cleaning and transfer operations. When it is necessary to pull the collection box 66, the handle 67 can be pulled directly, and the handle 67 drives the collection box 66 to move. The collection box 66 makes it more convenient to pull the collection box 66. The plastic material is relatively inexpensive, which greatly reduces the manufacturing cost of plastic materials.

[0036] When it is necessary to separate the items by bringing the scraper 71 into contact with the first magnetic separation conveyor belt 2, the threaded ring 75 can be rotated to drive the auxiliary rod 72 to slide downward along the inner wall of the connecting plate 73, so that the scraper 71 gradually approaches and contacts the surface of the first magnetic separation conveyor belt 2, thereby effectively scraping off the magnetic materials adsorbed on the conveyor belt, realizing the precise separation of magnetic materials and non-magnetic materials, improving sorting efficiency and material recovery rate. The slot 76 can increase the friction between the hand and the threaded ring 75, preventing slippage when rotating the threaded ring 75.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
