Description

Technical Field

[0001] This utility model relates to the field of non-metallic ore impurity removal technology, specifically a non-metallic ore impurity removal device for ore color sorting machines. Background Technology

[0002] In the field of non-metallic ore processing, ore color sorters are key equipment for achieving ore quality grading and impurity separation. Their core function is to distinguish the color differences between ores and impurities through optical recognition technology, thereby completing accurate sorting. However, during the mining and crushing process, non-metallic ores are easily mixed with impurities such as metal fragments and inferior ore blocks. If they are directly fed into the color sorter for sorting, it will seriously affect the sorting efficiency and the quality of the finished product.

[0003] Currently, the pretreatment and impurity removal methods for non-metallic ores in the industry are relatively simple. Most companies still use manual screening or simple vibrating screens for preliminary impurity removal. Manual screening is not only labor-intensive and inefficient, but also makes it difficult to accurately separate impurities with small particle size or similar color to the ore. The ore is prone to accumulate in the vibrating screen, forming screening dead zones, which makes the separation of impurities incomplete.

[0004] According to the patent application published on the Internet, a non-metallic ore impurity removal device for an ore color sorter (authorization announcement number: CN214812806U) is described as follows: the non-metallic ore impurity removal device for an ore color sorter includes a "base frame, impurity collection box", etc., to achieve the impurity removal work.

[0005] Regarding the above description, the applicant believes the following issues exist:

[0006] This ore color sorter uses a non-metallic ore impurity removal device, which utilizes a base frame and impurity collection box to remove impurities. When using this device, the non-metallic ore to be removed is poured into the ore placement box, and then the two handles are held to shake the ore placement box, which is connected to the movable bracket, back and forth to remove impurities. Manual operation not only results in a small shaking amplitude and low impurity removal quality, but also affects the efficiency of impurity removal due to long-term operation. Therefore, this device needs to be improved. Utility Model Content

[0007] The purpose of this utility model is to provide a non-metallic ore impurity removal device for ore color sorting machines, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a non-metallic ore impurity removal device for an ore color sorter, comprising a color sorter body, an impurity removal mechanism provided on the top of the color sorter body, and a material pushing mechanism provided on the front and rear sides of the impurity removal mechanism;

[0009] The impurity removal mechanism includes an impurity removal box, which is fixedly connected to the top of the color sorter body. A hopper is fixedly connected to the rear side of the impurity removal box, and a fixed frame is fixedly connected to the front side of the impurity removal box. A first hydraulic cylinder is fixedly connected to the front side of the fixed frame, and a connecting frame is fixedly connected to the rear side of the first hydraulic cylinder. A guide rod is fixedly connected to the front side of the connecting frame, and a screening frame is fixedly connected to the inner rear side of the connecting frame. An impurity box is fixedly connected to the bottom of the screening frame, and the impurity box is fixedly connected to the inner rear side of the connecting frame. Fixed seats are fixedly connected to the left and right sides of the impurity removal box, and a second hydraulic cylinder is fixedly connected to the top of the fixed seats. A mounting platform is fixedly connected to the top of the second hydraulic cylinder, and a servo motor is fixedly connected to the bottom inner side of the mounting platform. A rotating rod is fixedly connected to the bottom of the servo motor, and a stirring shaft is fixedly connected to the periphery of the rotating rod.

[0010] Preferably, the screening frame and the impurity box are slidably connected inside the impurity removal box, and the stirring shaft is rotatably connected inside the impurity removal box, so as to facilitate the stirring of the crushed non-metallic ore by the stirring shaft.

[0011] Preferably, the rotating rod is rotatably connected inside the mounting platform, the bottom of the impurity removal box is inclined inward around the perimeter, and the guide rod is slidably connected inside the fixed frame, so that the inclined setting can ensure the smooth feeding of the non-metallic ore after impurity removal.

[0012] Preferably, the servo motor, rotating rod, and stirring shaft are arranged in three sets and symmetrically distributed on the inner side of the mounting platform. By setting three sets, the overall stirring can be improved, thereby increasing the efficiency of impurity removal.

[0013] Preferably, the second hydraulic cylinder is provided in two sets, which are symmetrically distributed on the left and right sides of the bottom of the mounting platform. By providing two sets, the balance of the movement of the mounting platform can be ensured.

[0014] Preferably, the pushing mechanism includes a support base, which is fixedly connected to the left side of the impurity removal box. A third hydraulic cylinder is fixedly connected to the rear side of the support base, a connecting arm is fixedly connected to the front side of the third hydraulic cylinder, and a push plate is fixedly connected to the rear side of the connecting arm.

By setting two sets, when there are still residues in the non-metallic ore after impurity removal when it is transported into the color sorter body, it can be pushed to avoid residues.

[0016] Compared with the prior art, this utility model provides a non-metallic ore impurity removal device for ore color sorting machines, which has the following beneficial effects:

[0017] 1. This ore color sorter uses a non-metallic ore impurity removal device. Through its impurity removal mechanism, when removing impurities from non-metallic ores using the ore color sorter, the crushed non-metallic ore is first quantitatively fed into the impurity removal box via a hopper, positioned at the top of the screening frame. The volume of the ore must not exceed the bottom of the front side of the hopper. After feeding, three symmetrically distributed servo motors, rotating rods, and stirring shafts simultaneously stir the ore in the impurity removal box, preventing ore accumulation and screening dead zones. The rotation of the stirring shafts thoroughly disperses the ore, separating fine or lumpy impurities from the qualified ore. The ore is quickly separated, allowing impurities to pass through the screening frame and enter the impurity box for storage. After impurity removal, the first hydraulic cylinder drives the connecting frame, screening frame, and impurity box to move forward, causing the ore to fall from the screening frame to the bottom of the impurity box. At the same time, workers can clean the impurities from the left and right sides of the impurity box. The inward-sloping structure at the bottom of the impurity box guides the ore to converge at the feed inlet at the top of the color sorter, improving the feeding efficiency. When the screening frame moves forward, the second hydraulic cylinder drives the mounting platform, servo motor, and stirring shaft to move upward, avoiding obstruction of the ore feeding.

[0018] 2. The non-metallic ore impurity removal device used in this ore color sorter, through the set pusher mechanism, when the non-metallic ore after being crushed is removed by the screening frame, and when there is still residue at the bottom of the color sorter body after the screening frame is opened and the removed non-metallic ore is transported, two sets of symmetrically distributed third hydraulic cylinders can drive the connecting arm to move, thereby driving the pusher plate to slide in the impurity removal box, pushing the residual ore particles in the impurity removal box, avoiding the waste of residual ore, and ensuring the comprehensiveness of the feeding.

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-7 This utility model provides a technical solution: a non-metallic ore impurity removal device for an ore color sorter, including a color sorter body 1, an impurity removal mechanism 2 is provided on the top of the color sorter body 1, and a material pushing mechanism 3 is provided on the front and rear sides of the impurity removal mechanism 2.

[0033] The impurity removal mechanism 2 includes an impurity removal box 21, which is fixedly connected to the top of the color sorter body 1. A hopper 23 is fixedly connected to the rear side of the impurity removal box 21. A fixed frame 22 is fixedly connected to the front side of the impurity removal box 21. A first hydraulic cylinder 25 is fixedly connected to the front side of the fixed frame 22. A connecting frame 27 is fixedly connected to the rear side of the first hydraulic cylinder 25. A guide rod 26 is fixedly connected to the front side of the connecting frame 27. A screening frame 28 is fixedly connected to the inner rear side of the connecting frame 27. An impurity box 29 is fixedly connected to the bottom of the screening frame 28. The impurity box 29 is fixedly connected to the inner rear side of the connecting frame 27. Fixed seats 24 are fixedly connected to the left and right sides of the impurity removal box 21. A second hydraulic cylinder 291 is fixedly connected to the top of the fixed seat 24. A mounting platform 292 is fixedly connected to the top of the second hydraulic cylinder 291. A servo motor 293 is fixedly connected to the bottom inner side of the mounting platform 292. A rotating rod 294 is fixedly connected to the bottom of the servo motor 293. A stirring shaft 295 is fixedly connected to the periphery of the rotating rod 294.

[0034] Screening box 28 and impurity box 29 are slidably connected inside impurity removal box 21, and stirring shaft 295 is rotatably connected inside impurity removal box 21, so as to facilitate stirring of crushed non-metallic ore through stirring shaft 295.

[0035] The rotating rod 294 is rotatably connected to the inside of the mounting platform 292. The bottom of the impurity removal box 21 is inclined inward around the perimeter. The guide rod 26 is slidably connected to the inside of the fixed frame 22. The inclined setting facilitates the smooth feeding of the non-metallic ore after impurity removal.

[0036] The servo motor 293, the rotating rod 294, and the stirring shaft 295 are arranged in three sets and symmetrically distributed inside the mounting platform 292. By setting three sets, the overall stirring can be improved, thereby improving the efficiency of impurity removal.

[0037] Two sets of the second hydraulic cylinder 291 are provided and symmetrically distributed on the left and right sides of the bottom of the mounting platform 292. By setting two sets, the balance of the movement of the mounting platform 292 can be guaranteed.

[0038] Example 2

[0039] Please see Figure 1-7 Furthermore, based on Embodiment 1, the pushing mechanism 3 includes a support base 31, which is fixedly connected to the left side of the impurity removal box 21. A third hydraulic cylinder 32 is fixedly connected to the rear side of the support base 31. A connecting arm 33 is fixedly connected to the front side of the third hydraulic cylinder 32. A push plate 34 is fixedly connected to the rear side of the connecting arm 33. The push plate 34 is slidably connected inside the impurity removal box 21.

[0040] The pusher plate 34 is trapezoidal. The support base 31, the third hydraulic cylinder 32, the connecting arm 33 and the pusher plate 34 are arranged in two sets and symmetrically distributed on the front and rear sides of the impurity removal box 21. By setting two sets, when there are still residues in the non-metallic ore after impurity removal when it is transported into the color sorter body 1, it can be pushed to avoid residues.

[0041] In actual operation, when this device is used, when the non-metallic ore is removed by the ore color sorter, the screening frame 28 and the impurity box 29 are placed inside the impurity removal box 21 under the action of the first hydraulic cylinder 25. The crushed non-metallic ore is conveyed to the impurity removal box 21 in a quantitative form through the hopper 23, and is located at the top of the screening frame 28. The volume of the ore cannot exceed the bottom position of the front side of the hopper 23.

[0042] After the input is completed, the three symmetrically distributed servo motors 293, rotating rods 294 and stirring shafts 295 can simultaneously stir the ore in the impurity removal box 21 to avoid the accumulation of ore and the formation of screening dead corners. The rotation of the stirring shaft 295 can fully disperse the ore, so that the fine impurities or blocky impurities mixed in the ore can be quickly separated from the qualified ore. The impurities can be stored in the impurity box 29 through the screening frame 28. After the impurity removal is completed, the second hydraulic cylinder 291 drives the mounting platform 292, servo motors 293 and stirring shafts 295 to move upward, so that the stirring shaft 295 is located at the top of the impurity removal box 21, so as to avoid obstructing the feeding of ore.

[0043] At this time, the first hydraulic cylinder 25 can drive the connecting frame 27, the screening frame 28 and the impurity box 29 to move forward, so that the ore falls from the screening frame 28 to the bottom of the impurity removal box 21. At the same time, the staff can clean the impurities from the left and right sides of the impurity box 29. The structure design of the bottom of the impurity removal box 21, which is inclined inward, can guide the ore to converge at the feed inlet at the top of the color sorter body 1, thereby improving the efficiency of feeding.

[0044] When the non-metallic ore after crushing is removed by the screening frame 28, and there is still residue at the bottom of the color sorter body 1 after the screening frame 28 is opened and the removed non-metallic ore is transported to the bottom, the connecting arm 33 and the push plate 34 are moved by the third hydraulic cylinder 32. The two sets of symmetrically distributed third hydraulic cylinders 32 can drive the connecting arm 33 to move, thereby driving the push plate 34 to slide in the impurity removal box 21 to push the residual ore particles in the impurity removal box 21, so as to avoid the waste of ore residue and ensure the comprehensiveness of feeding.

[0045] When the ore that has been cleaned of impurities enters the color sorter body 1 through the feed inlet at the top of the color sorter body 1, it can be processed for the next step. At the same time, the ore that has not been cleaned of impurities is put back into the hopper 23 to continue the cleaning work.

[0046] In this application, all the first hydraulic cylinder 25, the second hydraulic cylinder 291, the third hydraulic cylinder 32, the servo motor 293, and the color sorter body 1 need to be connected to the same PLC controller to ensure the coordinated and automated operation of the equipment. The PLC controller is existing technology, and those skilled in the art are well aware of its operation method, so it will not be described in detail here.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
