Description

Technical Field

[0001] This application relates to the field of ore cleaning technology, and in particular to an ore cleaning device for mineral processing. Background Technology

[0002] Currently, mined ores typically exist as mixed solid blocks of varying sizes. After being crushed and ground by specialized equipment, the desired minerals are separated from other associated substances using chemical or physical methods. Since mined ores are often covered with impurities such as mud, they require specialized washing equipment to clean them before further crushing and beneficiation.

[0003] Related technology can be found in Chinese patent application CN215278878U, which discloses an ore washing device for mineral processing. The device includes a mounting base, a washing cylinder connected to the top surface of the mounting base via a connecting mechanism, and the connecting mechanism being symmetrically arranged on the top surface of the mounting base and connected to the washing cylinder via a gear ring fitted onto the outer wall of the washing cylinder. An engagement mechanism is provided between the washing cylinder and the mounting base. A bearing mechanism is connected to the inner cavity of the washing cylinder via a rodless cylinder. First mounting recesses are symmetrically arranged on the top surface of the mounting base, and a gear-type connecting ring is connected to the inner cavity of the first mounting recess via a rotating shaft. A reducer is connected to the input end of the rotating shaft, and a drive motor is connected to the input end of the reducer, facilitating overall rotation and effectively providing a water washing method during flow. This improves the comprehensiveness and thoroughness of ore washing, effectively discharging the washed liquid while washing, resulting in a thorough cleaning of the ore surface.

[0004] Regarding the aforementioned technologies, after cleaning the ore surface, water is discharged from the water outlet mesh layer, resulting in a significant waste of water resources. Furthermore, the fallen silt and impurities, as well as small particles from the ore, can clog the permeable mesh layer, making it difficult to remove impurities generated during subsequent cleaning processes. During the rotation of the cleaning cylinder, impurities can fall back into the cylinder and adhere to the ore surface, resulting in low ore cleaning efficiency. Utility Model Content

[0005] In order to improve the efficiency of removing impurities from ore, this application provides an ore washing device for mineral processing.

[0006] This application provides an ore washing device for mineral processing, which adopts the following technical solution:

[0018] By adopting the above technical solution, when impurities and small ores fall from the outlet, the inclined plate receives the ores, the small ores pass through the discharge port along the inclined plate and are collected, and water and impurities move through the through holes to the bottom of the support, which improves the convenience of separating large and small ores.

[0019] Optionally, a guide plate is provided below the inclined plate. The guide plate is slidably connected to the bracket in the vertical direction and is set parallel to the inclined plate. Several cylindrical rods are fixed in the upper part of the guide plate in the vertical direction. The cylindrical rods are directly opposite the through holes. A lifting component is provided on the side of the bracket near the receiving plate. The lifting component is used to drive the guide plate to move up and down in the vertical direction.

The drain pipes are connected to the water tank. The drain pipes are directly opposite the lower end of the guide plate. A permeable plate is fixed on the side of the drain pipe near the guide plate.

[0022] By adopting the above technical solution, the guide plate guides impurities and water, the permeable plate blocks impurities, and the water flows back into the water tank through the drain pipe, thus improving the water utilization rate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When the ore is inside the opening, the cylinder rotates, and the ore pushes the lever.

The first circular plate 24 and the second circular plate 25 work together to limit the connecting pipe 12, which helps to reduce the probability of the cylinder 11 shifting during rotation and improves the convenience of the cylinder 11 rotation and the stability of the cylinder 11 during rotation.

[0038] Reference Figure 3 The support assembly 4 is located inside the bracket 1, on the side of the cylinder 11 away from the connecting pipe 12. The support assembly 4 is used to support the cylinder 11. The support assembly 4 includes multiple rollers 41, which are rotatably connected to the side of the bracket 1 away from the connecting pipe 12 and located inside the bracket 1. The rollers 41 are arranged along the length of the cylinder 11. The cylinder 11 is in contact with the multiple rollers 41 and is in rolling contact with the rollers 41. When the cylinder 11 rotates, the cylinder 11 drives the multiple rollers 41 to rotate, which helps to reduce the wear between the cylinder 11 and the bracket 1 and improves the service life of the cylinder 11.

[0039] Reference Figure 1 and Figure 3An arc-shaped plate 14 is fixedly installed inside the cylinder 11 for conveying ore.

[0040] Reference Figure 1 A receiving plate 15 is fixed on the side of the support 1 away from the connecting pipe 12. The receiving plate 15 is directly opposite the lower end of the cylinder 11. The washed ore slides off the receiving plate 15 to the collection point. Multiple openings 13 are opened on the side of the cylinder 11 near the receiving plate 15. The multiple openings 13 are evenly arranged along the circumference and axial direction of the cylinder 11. Small ore and impurities fall into the interior of the support 1 through the through holes 51.

The two ends of the first elastic element 162 are fixedly connected to the support rod 16 and the lever 161 respectively. When the ore is stuck in the opening 13, the ore pushes the lever 161, and the lever 161 rotates around the support rod 16. The first elastic element 162 drives the lever 161 to reset, thereby pushing the ore into the cylinder 11, so that other small ores and impurities fall out from the opening 13.

[0042] Reference Figure 3 and Figure 6On the side of the support 1 away from the support rod 16, a plurality of support blocks 17 are fixedly provided.

In the natural state, the second elastic element 173 keeps the hemispherical block 172 in the opening 13 and the cylinder 11 rotates. When the hemispherical block 172 is not in the opening 13, it is in the groove and squeezes the second elastic element 173. When the cylindrical block 171 is directly opposite the opening 13, the second elastic element 173 pushes the hemispherical block 172 into the opening 13, further pushing the ore in the opening 13 into the cylinder 11, so that other small ores and impurities fall out from the opening 13, thereby improving the efficiency of impurity removal from the ore.

The inclined plate 5 is inclined from top to bottom along the direction from the support rod 16 towards the support block 17. A discharge port 56 is opened on the side of the support 1 near the support block 17. The discharge port 56 is set along the length of the support 1 and is directly opposite the inclined plate 5. When impurities and small ores fall from the opening 13, the inclined plate 5 catches the ores, and the small ores pass through the discharge port 56 along the inclined plate 5 for collection. The inclined plate 5 has multiple through holes 51 opened vertically. Water and impurities move towards the bottom of the support 1 through the through holes 51, which improves the convenience of separating large and small ores.

The guide plate 52 is slidably connected to the bracket 1 along the vertical direction and is set parallel to the inclined plate 5. Multiple cylindrical rods 53 are fixed vertically at the upper end of the guide plate 52. The cylindrical rods 53 are directly opposite the through hole 51.

[0045] Reference Figure 3A guide plate 55 is provided at the lower end of the guide plate 52. The guide plate 55 is fixedly connected to the bracket 1. The guide plate 55 is inclined from top to bottom along the direction from the support block 17 to the support rod 16. Multiple drain pipes 311 are connected to the side of the bracket 1 near the water tank 31. The drain pipes 311 are connected to the water tank 31. The lower end of the drain pipes 311 is directly opposite the guide plate 55. A permeable plate 312 is fixedly provided on the side of the drain pipes 311 near the guide plate 55. The guide plate 55 guides impurities and water, and the permeable plate 312 blocks impurities. Water flows back into the water tank 31 through the drain pipes 311, which improves the utilization rate of water resources.

[0046] The implementation principle of the ore washing device for mineral processing according to this application embodiment is as follows: the water pump 33 draws water from the water tank 31 through the water pumping pipe 32 and sprays it out from the nozzle 35 through the water delivery pipe 34. The washed water passes through the through-hole 13 and the through hole 51 in sequence, and flows along the guide plate 52 and the guide plate 55 to the bottom of the support 1, and then flows back into the water tank 31 through the drain pipe 311. When the ore is in the through-hole 13, the cylinder 11 rotates, and the ore pushes the lever 161, which rotates around the support rod 16. The first elastic element 162 drives the lever 161 to reset, thereby pushing the ore into the cylinder 11. When the hemispherical block 172 is not in the opening 13, the hemispherical block 172 is in the groove and squeezes the second elastic element 173. When the cylindrical block 171 is aligned with the opening 13, the second elastic element 173 pushes the hemispherical block 172 into the opening 13, further pushing the ore in the opening 13 into the cylinder 11, so that other small ores and impurities fall out of the opening 13, improving the efficiency of impurity removal from the ore.
