Description

Technical Field

[0001] This utility model relates to the field of ore screening technology, and in particular to an energy-saving ore screening device. Background Technology

[0002] Ore screening is the process of separating valuable minerals from waste rock in ore using physical or chemical methods. It includes steps such as crushing, screening, gravity separation, flotation, and magnetic separation. Its purpose is to improve ore grade, facilitating subsequent smelting or processing. Screening methods are selected based on mineral properties (such as density, magnetism, and surface characteristics), which can significantly improve resource utilization and reduce transportation and processing costs.

[0003] However, most ore screening equipment generates significant dust during the screening process due to the large amplitude of the vibrating screen. The dust suppression water spray heads are fixed in position and cannot be moved, so they cannot achieve uniform and effective dust suppression. In addition, traditional screening equipment can only perform primary screening and cannot screen the ore into different particle sizes according to the usage requirements, which greatly reduces the practicality of the equipment.

[0004] Therefore, those skilled in the art have provided an energy-saving ore screening device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide an energy-saving ore screening device. The device uses a controller to control a first servo motor that drives a bidirectional threaded rod to rotate. This causes two sliders, fitted at both ends of the bidirectional threaded rod's outer wall, to slide in opposite directions. During this sliding process, a water supply pipe running through the sliders delivers dust-suppressing water to a collection box at the lower end, supplied by an external water source. The collection box then sprays water through nozzles distributed throughout it. Simultaneously, a gear ring fixed to the outer wall of the collection box, connected to a bearing at the lower end of the water supply pipe, meshes with and rotates with the rack during slider movement. This results in a wider spray range for the water mist from the nozzles. Combined with the reciprocating sliding of the sliders, this enhances the dust suppression effect, eliminating the need for multiple water spray points and improving dust suppression efficiency, thus increasing the device's practicality.

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

[0007] An energy-saving ore screening device includes a main body, a controller, a feed hopper, a feeding plate, and an inspection port. The upper part of the main body is equipped with a high-efficiency dust reduction mechanism, and the middle and lower parts of the main body are equipped with multi-stage screening mechanisms.

[0008] The high-efficiency dust suppression mechanism includes a first servo motor, the output end of which is fixedly connected to a bidirectional threaded rod. Both ends of the outer wall of the bidirectional threaded rod are fitted with sliders. A water supply pipe is fitted inside the middle of the slider. The lower end of the water supply pipe is fixedly connected to a connecting block. A bearing is fixedly connected to the outer wall of the connecting block. A sealing ring is provided on one side of the outer wall of the bearing. A gear ring is fixedly connected to one side of the outer wall of the bearing. A water collection box is fixedly connected to the lower end of the gear ring. Multiple nozzles are fixedly connected to one side and the lower end face of the outer wall of the water collection box. A rack is fixedly connected to the upper end of the inner wall of the device body. Water inlets are opened at both ends of the upper end face of the device body.

[0009] Through the above technical solution, the device controls the first servo motor to drive the bidirectional threaded rod to rotate, thereby enabling the two sliders sleeved at both ends of the outer wall of the bidirectional threaded rod to slide in opposite directions. During the sliding process, the water supply pipe passing through the slider delivers dust suppression water to the water collection box at the lower end under the supply of an external water source. The water collection box sprays water out through the nozzles distributed on it. At the same time, the gear ring fixed to the outer wall of the water collection box is fixedly connected to the connecting block at the lower end of the water supply pipe with a bearing, so it can mesh and rotate with the rack when the slider slides, making the water mist sprayed by the nozzles spread over a wider range. Combined with the reciprocating sliding of the sliders in opposite directions, the dust suppression effect is better, eliminating the need to set up multiple water spray dust suppression points, improving dust suppression efficiency, and thus improving the practicality of the device.

[0010] Furthermore, the multi-stage screening mechanism includes two second servo motors, the output ends of the second servo motors are fixedly connected to an eccentric wheel, one end of one side face of the eccentric wheel is rotatably connected to a connecting rod, one end of one of the connecting rods is rotatably connected to a first screen plate, the middle and lower ends of both ends of the inner wall of the device body are provided with sliding grooves, one end of the other connecting rod is rotatably connected to a second screen plate, and a collection box is slidably connected to the lower end inside the device body;

[0011] Through the above technical solution, the device controls the second servo motor to drive the eccentric wheel to rotate via the controller. The rotation of the eccentric wheel causes the connecting rod to move the first screen plate back and forth on the slide groove due to the change in the position of one end. Similarly, the second screen plate set below the first screen plate also moves back and forth on the slide groove. Because the diameter of the eccentric wheel in the same layer as the second screen plate is smaller than that of the eccentric wheel in the layer where the first screen plate is located, the amplitude of the second screen plate's back and forth sliding vibration is smaller than that of the first screen plate. However, the length of the second screen plate is also greater than that of the first screen plate. Therefore, the second screen plate can promptly receive the finer particles of ore screened from the first screen plate, while the coarser particles of ore are left in the first screen plate with larger screen holes. The ore screened by the second screen plate is collected by the collection box, which facilitates the multi-stage screening of the device and thus improves the practicality of the device.

[0012] Furthermore, a controller is provided at the upper end of one side face of the main body of the device, and a feed hopper is fixedly connected to the upper end of one side face of the main body of the device;

[0013] Through the above technical solution, the controller is used to coordinate the operation of the entire device, and the feed hopper is used to put in the crushed ore to be screened.

[0014] Furthermore, a material handling plate is rotatably connected to the middle and lower ends of both sides of the main body of the device, and an inspection port is opened on the middle and lower ends of one side of the main body of the device.

[0015] Through the above technical solution, the material receiving plate is used to remove the ore left on the screening disc after screening, and the inspection port is used to check the condition of the second servo motor and related components and to carry out maintenance when necessary.

[0016] Furthermore, two sliders are slidably connected to the upper ends of both sides of the inner wall of the main body of the device, and one end of the water supply pipe passes through the middle of one side end face of the slider and forms a fixed connection with the connecting block;

[0017] Through the above technical solution, the slider is used to support the water supply pipe and the water spray dust suppression components, and the inner wall of the main body of the device is used as the sliding limit, which improves the sliding stability of the slider and the water spray dust suppression components.

[0018] Furthermore, one side of the outer wall of the gear ring and one side of the outer wall of the rack form a meshing connection;

[0019] Through the above technical solution, the gear ring meshes with the rack and rotates when the slider slides, which makes the water mist sprayed from the nozzle spread over a wider range.

[0020] Furthermore, one end face of the first screen plate is slidably connected to one end face of the slide groove, and one end face of the second screen plate is slidably connected to one end face of the slide groove.

[0021] Through the above technical solution, the sliding of the first screen plate and the second screen plate is more stable and the sliding groove can play an auxiliary role in fixing the screen plate.

[0022] Furthermore, the aperture of the first screen plate is larger than that of the second screen plate, the length of the second screen plate is greater than that of the first screen plate, the first screen plate is located above the second screen plate, and the diameter of the eccentric wheel connected to the second screen plate is smaller than that of the eccentric wheel connected to the first screen plate.

[0023] Through the above technical solution, the second screen can promptly receive the finer particles of ore that have been screened by the first screen, while the coarser particles of ore are left in the first screen with larger screen holes. The ore that is screened by the second screen is collected by the collection box, which facilitates the multi-stage screening of the device.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes an energy-saving ore screening device. The device uses a controller to control a first servo motor to drive a bidirectional threaded rod to rotate, which in turn allows two sliders fitted at both ends of the outer wall of the bidirectional threaded rod to slide in opposite directions. During the sliding process, a water supply pipe passing through the slider delivers dust-suppressing water to a water collection box at the lower end under the supply of an external water source. The water collection box sprays water out through nozzles distributed throughout it. At the same time, the gear ring fixed to the outer wall of the water collection box is fixedly connected to the lower end connecting block of the water supply pipe with a bearing, so it can mesh and rotate with the rack when the slider slides, making the water mist sprayed by the nozzles spread over a wider range. Combined with the reciprocating sliding of the sliders in opposite directions, the dust suppression effect is better. There is no need to set up multiple water spray dust suppression points, which improves the dust suppression efficiency and thus improves the practicality of the device.

[0026] 2. This utility model proposes an energy-saving ore screening device. The device uses a controller to control a second servo motor to drive an eccentric wheel to rotate. The rotation of the eccentric wheel causes the connecting rod to move the first screen plate back and forth on the slide groove due to the change in the position of one end. Similarly, the second screen plate, which is set below the first screen plate, also moves back and forth on the slide groove.

Therefore, the second screen plate can promptly receive the finer particles of ore screened by the first screen plate, while the coarser particles of ore are left in the first screen plate with larger screen holes. The ore screened by the second screen plate is collected by the collection box, which facilitates the multi-stage screening of the device and improves its practicality. Attached Figure Description

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Reference Figure 1-3 This utility model provides a specific implementation method:

[0038] An energy-saving ore screening device includes a main body 1, a controller 2, a feed hopper 3, a feeding plate 4, and an inspection port 7. A high-efficiency dust suppression mechanism 5 is installed at the upper end of the main body 1, and a multi-stage screening mechanism 6 is installed in the middle and lower parts of the main body 1. The high-efficiency dust suppression mechanism 5 includes a first servo motor 51, with a bidirectional threaded rod 52 fixedly connected to the output end of the first servo motor 51. Slider blocks 53 are fitted at both ends of the outer wall of the bidirectional threaded rod 52. A water supply pipe 54 is fitted inside the middle of the slider 53. A connecting block 55 is fixedly connected to the lower end of the water supply pipe 54. A bearing 56 is fixedly connected to the outer wall of the connecting block 55. A sealing ring 57 is provided on one side of the outer wall of the bearing 56. A gear ring 58 is fixedly connected to one side of the outer wall of the bearing 56. A water collection box 59 is fixedly connected to the lower end of the gear ring 58. Multiple nozzles 510 are fixedly connected to one side and the lower end of the outer wall of the water collection box 59. The upper end of the inner wall of the main body 1 is fixedly connected to... The device is equipped with a rack 511, and water inlets 512 are provided at both ends of the upper surface of the main body 1. The device controls the first servo motor 51 through the controller 2 to drive the bidirectional threaded rod 52 to rotate, thereby enabling the two sliders 53 sleeved at both ends of the outer wall of the bidirectional threaded rod 52 to slide in opposite directions. During the sliding process, the water supply pipe 54 passing through the slider 53 delivers dust suppression water to the water collection box 59 at the lower end under the supply of an external water source. The water collection box 59 sprays water out through the nozzles 510 distributed on it. At the same time, the gear ring 58 fixed on the outer wall of the water collection box 59 is fixedly connected to the bearing 56 between it and the lower end connecting block 55 of the water supply pipe 54. Therefore, it can mesh and rotate with the rack 511 when the slider 53 slides, so that the water mist sprayed by the nozzles 510 has a larger dispersion range. Combined with the reciprocating sliding of the slider 53 in opposite directions, the dust suppression effect is better. There is no need to set up multiple water spray dust suppression points, which improves the dust suppression efficiency and thus improves the practicality of the device.

[0039] Reference Figure 3-7The multi-stage screening mechanism 6 includes two second servo motors 61. An eccentric wheel 62 is fixedly connected to the output end of each second servo motor 61. A connecting rod 63 is rotatably connected to one end of one side of the eccentric wheel 62. One end of one connecting rod 63 is rotatably connected to a first screen disc 64. Slide grooves 65 are provided at the middle and lower ends of both ends of the inner wall of the device body 1. One end of the other connecting rod 63 is rotatably connected to a second screen disc 66. A collection box 67 is slidably connected to the lower end of the device body 1. The device controls the second servo motors 61 via the controller 2 to drive the eccentric wheel 62 to rotate. The rotation of the eccentric wheel 62 causes the connecting rod 63 to move due to the change in the position of one end, causing the first screen disc 64 to reciprocate on the slide groove 65. Similarly, the second screen 66, located below the first screen 64, also slides back and forth on the chute 65. Because the diameter of the eccentric wheel 62, which is in the same layer as the second screen 66, is smaller than that of the eccentric wheel 62 in the layer where the first screen 64 is located, the amplitude of the second screen 66's reciprocating sliding vibration is smaller than that of the first screen 64. However, the length of the second screen 66 is also greater than that of the first screen 64. Therefore, the second screen 66 can promptly receive the finer particles of ore screened from the first screen 64, while the coarser particles of ore remain in the first screen 64 with larger screen holes. The ore screened by the second screen 66 is then collected by the collection box 67, which facilitates the multi-stage screening of the device and improves the practicality of the device.

[0040] A controller 2 is installed at the upper end of one side face of the main body 1, and a feed hopper 3 is fixedly connected to the upper end of one side face of the main body 1. The controller 2 is used to coordinate the operation of the entire device, and the feed hopper 3 is used to put in the crushed ore to be screened.

[0041] The middle and lower ends of both sides of the main body 1 are rotatably connected to the material receiving plate 4. The middle and lower ends of one side of the main body 1 are provided with the inspection port 7. The material receiving plate 4 is used to remove the ore left on the screening plate after screening. The inspection port 7 is used to check the condition of the second servo motor 61 and related components and to perform maintenance when necessary.

[0042] Two sliders 53 are slidably connected to the upper ends of the inner walls of the main body 1. One end of the water supply pipe 54 passes through the middle of one side end face of the slider 53 and forms a fixed connection with the connecting block 55. The slider 53 is used to support the water supply pipe 54 and the water spray dust suppression component, and the inner wall of the main body 1 is used as the sliding limit, which improves the sliding stability of the slider 53 and the water spray dust suppression component.

[0043] One side of the outer wall of the gear ring 58 is meshed with one side of the outer wall of the rack 511. When the slider 53 slides, the gear ring 58 meshes with the rack 511 and rotates, so that the water mist sprayed by the nozzle 510 has a larger dispersion range.

[0044] One end face of the first screen plate 64 is slidably connected to one end face of the slide groove 65, and one end face of the second screen plate 66 is slidably connected to one end face of the slide groove 65. The sliding of the first screen plate 64 and the second screen plate 66 is more stable and the slide groove 65 can play an auxiliary fixing role for the screen plate.

[0045] The aperture of the first screen plate 64 is larger than that of the second screen plate 66, and the length of the second screen plate 66 is greater than that of the first screen plate 64. The first screen plate 64 is located above the second screen plate 66. The diameter of the eccentric wheel 62 connected to the second screen plate 66 is smaller than that of the eccentric wheel 62 connected to the first screen plate 64. The second screen plate 66 can promptly receive the finer particles of ore screened by the first screen plate 64, while the coarser particles of ore are left in the first screen plate 64 with larger apertures. The ore screened by the second screen plate 66 is collected by the collection box 67, which facilitates the multi-stage screening of the device.

[0046] Working principle: The device controls the first servo motor 51 through controller 2 to drive the bidirectional threaded rod 52 to rotate, thereby enabling the two sliders 53 sleeved at both ends of the outer wall of the bidirectional threaded rod 52 to slide in opposite directions. During the sliding process, the water supply pipe 54 passing through the slider 53 delivers dust suppression water to the lower water collection box 59 under the supply of an external water source. The water collection box 59 sprays water out through the nozzles 510 distributed on it. At the same time, the gear ring 58 fixed to the outer wall of the water collection box 59 is fixedly connected to the lower end connecting block 55 of the water supply pipe 54 by a bearing 56. Therefore, it can mesh and rotate with the rack 511 when the slider 53 slides, so that the water mist sprayed by the nozzles 510 has a larger dispersion range. Combined with the reciprocating sliding of the slider 53 in opposite directions, the dust suppression effect is better. The device controls the second servo motor 51 through controller 2 to rotate the bidirectional threaded rod 52. Servo motor 61 drives eccentric wheel 62 to rotate. The rotation of eccentric wheel 62 causes the connecting rod 63 to move the first screen plate 64 back and forth on the slide groove 65 due to the change in the position of one end. Similarly, the second screen plate 66 set below the first screen plate 64 also moves back and forth on the slide groove 65. Since the diameter of the eccentric wheel 62 in the same layer as the second screen plate 66 is smaller than that of the eccentric wheel 62 in the layer where the first screen plate 64 is located, the amplitude of the second screen plate 66's back and forth sliding vibration is smaller than that of the first screen plate 64. However, the length of the second screen plate 66 is also greater than that of the first screen plate 64. Therefore, the second screen plate 66 can promptly receive the finer particles of ore screened from the first screen plate 64, while the coarser particles of ore are left in the first screen plate 64 with larger screen holes. The ore screened by the second screen plate 66 is collected by the collection box 67.
