Description

Technical Field

[0001] This application relates to the field of conveying equipment technology, and more specifically, to a bauxite material conveying system. Background Technology

[0002] Bauxite is an important industrial raw material, mainly used in aluminum smelting, refractory materials, abrasives, and other fields. Its main component is aluminum oxide (Al2O3), which has properties such as high hardness, wear resistance, and high temperature resistance.

[0003] In the production and processing of bauxite, the conveying of crushed bauxite material is a crucial link connecting various processing and refining steps. Traditional conveying equipment usually uses belt conveyors or screw conveyors. When conveying dry bauxite, the vibration and friction generated by the motor of the equipment can easily cause dust to be generated from the crushed bauxite material. This not only causes material loss during the conveying process and increases production costs, but also pollutes the working environment and affects the health of operators. Furthermore, the bauxite dust generated is easily attracted to the conveying equipment due to static electricity and is difficult to remove on its own, requiring manual cleaning and also causing conveying losses.

[0004] Therefore, we propose a bauxite material conveying system to solve the existing problems. Utility Model Content

[0028] like Figures 1 to 4As shown, a bauxite material conveying system includes a conveyor line 1 installed at an incline on a horizontal ground. A conveyor belt 12 is rolled along the conveyor line 1. Several auxiliary support roller groups 11 are provided between the top end face of the conveyor line 1 and the conveyor belt 12. A feeding assembly 5 is provided above one bottom end of the conveyor line 1. The bottom of the feeding assembly 5 has a discharge port 14. A screening assembly 3 is installed below the discharge port 14. A dust collection assembly 4 is provided on the screening assembly 3. A dust suppression assembly 6 is installed above the conveyor line 1. The dust suppression assembly 6 includes a first water supply pipe 61 and a third water supply pipe 64 arranged parallel to the conveyor line 1. The third water supply pipe 64 is located between the screening assembly 3 and the conveyor line 1. The first water supply pipe 61 is located above the conveyor line 1 at the end away from the third water supply pipe 64. In use, the auxiliary support roller groups 11 are used to support the conveyor belt. Conveyor belt 12 is used for auxiliary conveying of bauxite material. Feeding component 5 is used to convey bauxite to screening component 3 for sieving. After screening, bauxite particles are discharged from screening component 3 and fall onto conveyor belt 12 for conveying. Dust collection component 4 is used to generate negative pressure to collect dust generated by screening component 3 during the vibrating screening process. Dust suppression component 6 is used to spray water onto conveyor belt 12 through first water supply pipe 61 and third water supply pipe 64 set above conveyor line 1 to wet the surface of conveyor belt 12, allowing the bauxite on conveyor belt 12 to absorb water and clump together, suppressing dust generated by vibration during the conveying of bauxite, thereby reducing conveying loss. At the same time, the bauxite clumps after absorbing water and clumping can be more easily removed from conveyor belt 12, avoiding bauxite particles being adsorbed on the conveying system due to electrostatic effect and difficult to clean.

[0029] In this embodiment, one end of the first water supply pipe 61 is positioned above the conveyor belt 12, and several second water supply pipes 62 are equidistantly arranged along the length direction, connecting and penetrating the first water supply pipe 61. The bottom of the second water supply pipe 62 has a first nozzle 63, which faces the end face of the conveyor belt 12. One end of the third water supply pipe 64 is positioned above the conveyor belt 12, and the bottom has a second nozzle 65 perpendicular to the end face of the conveyor belt 12. The first water supply pipe 61 sprays water onto the end face of the conveyor belt 12 through the connected second water supply pipes 62 and the first nozzle 63 installed at the bottom of the second water supply pipes 62, to cause the bauxite to absorb water and clump together during the conveying process. The third water supply pipe 64 is installed between the screening component 3 and the conveyor belt 12, and the second nozzle 65 at its bottom sprays water onto the end face of the conveyor belt 12, to cause the bauxite discharged from the screening hopper 34 after screening to absorb water and clump together. This achieves spraying at different positions on the conveyor belt 12, causing the bauxite to absorb water and clump together, thus playing a dust suppression role.

[0030] In this embodiment, the first water supply pipe 61 and the third water supply pipe 64 are both fixedly connected to the bracket 2 through pipe sleeves. The two ends of the second water supply pipe 62 away from the first water supply pipe 61 are fixedly connected to the transmission line 1 through support rods to ensure a stable connection between the water supply pipe and the bracket 2. The ends of the first water supply pipe 61 and the third water supply pipe 64 away from the transmission line 1 are each provided with a connecting flange 66 for connecting to the water source.

[0031] In this embodiment, a support 2 is also installed at the bottom end of the conveyor line 1. The feeding component 5 and the screening component 3 are installed inside the support 2 from top to bottom. A buffer component 31 is installed between the support 2 and the screening component 3 to reduce the vibration transmission effect generated by the screening component 3 when the screening component 3 is working, so as to ensure the stable operation of the conveying system.

[0032] In this embodiment, the screening component 3 includes a screening bucket 34 arranged parallel to the conveyor line 1. The top of the screening bucket 34 has an opening that communicates with the feeding component 5, and the bottom has an outlet that communicates with the conveyor belt 12. Inside the screening bucket 34, from top to bottom, there are a first screen 36 and a second screen 37. The aperture of the screen holes on the first screen 36 is larger than the aperture of the screen holes on the second screen 37. The side wall of the screening bucket 34 between the first screen 36 and the second screen 37 is provided with an openable and closable baffle 35. In use, bauxite enters the screening bucket 34 from the feeding component 5 and passes through the first screen 36 and the second screen 37 in sequence. Bauxite particles that meet the size requirements pass through the second screen 37 and fall onto the conveyor belt 12 for conveying. Large particles remain on the first screen 36 or pass through the first screen 36 and remain on the second screen 37. The bauxite material remaining on the first screen 36 is discharged from the top opening of the screening bucket 34, and the bauxite material remaining on the second screen 37 is discharged by opening the baffle 35.

[0033] In this embodiment, a rotating shaft is rotatably connected to the screen bucket 34 in the width direction. The rotating shaft passes through both ends of the screen bucket 34 and is equipped with eccentric wheels 32. The rotating shaft is connected to a drive motor 33 via a belt. The drive motor 33 is fixedly installed on the outer end of the side wall of the screen bucket 34. When in use, the drive motor 33 rotates, which drives the rotating shaft to rotate via the belt. The rotating shaft drives the eccentric wheels to rotate, generating centrifugal force, which causes the screen bucket 34 to vibrate and screen bauxite.

[0034] In this embodiment, the dust collection assembly 4 includes a dust collection hood 41, which is detachably installed on the end of the opening of the screen hopper 34 away from the end connected to the feeding assembly 5. A connecting pipe 42 is connected to the side end of the dust collection hood 41, and a dust collection box 43 is connected to the other end of the connecting pipe 42. An air pump 44 is installed on one side of the dust collection box 43. The air pump 44 generates negative pressure when it works, and sucks the dust generated during the screening process into the dust collection box 43 through the connecting pipe 42 for collection. The dust collection box 43 is used to collect the bauxite dust that is raised due to vibration during screening, which is convenient for subsequent recycling and at the same time prevents the dust from spreading and polluting the environment of the conveying system.

[0035] In this embodiment, the feeding assembly 5 includes a hopper 51 fixedly installed on the inner side of the top of the support 2 and a driving cylinder 53. The driving cylinder 53 is hinged to the outer side wall of the hopper 51. The bottom of the hopper 51 has a discharge port 14 that communicates with the opening of the screen hopper 34. A feeding plate 52 is provided on the discharge port 14. One end of the feeding plate 52 is movably hinged to the side wall of the discharge port 14, and the other end of the feeding plate 52 is fixedly connected to the output end of the driving cylinder 53. When the driving cylinder 53 works, it drives the feeding plate 52 to open and close, thereby controlling the flow rate of bauxite from the discharge port 14 into the screen hopper 34.

[0036] In this embodiment, a feeding bin 13 is installed at the top of the conveyor line 1. One end of the feeding bin 13 is connected to the conveyor belt 12, and the bottom of the other end is provided with a guide outlet. When in use, the feeding bin 13 is installed at the top of the conveyor line 1, and one end is connected to the conveyor belt 12 to receive the conveyed bauxite. The bottom of the feeding bin 13 has a guide outlet to guide the bauxite material to be collected and output to a designated position.

[0037] In this embodiment, the auxiliary support roller group 11 includes two rollers arranged along the conveying direction perpendicular to the conveyor belt 12. The two rollers are installed on the conveyor line 1 in a “V” symmetrical structure and both rollers are rotatably connected to the conveyor belt 12 to ensure the stability of the bauxite material during the conveying process, prevent the conveyor belt 12 from deviating or slipping, and bear the overall weight of the bauxite after absorbing water to ensure smooth conveying.

[0038] The specific working principle of this utility model is as follows: Material is fed from one end of the hopper 51 of the feeding component 5 under the control of the driving cylinder 53. After the bauxite material enters the screen hopper 34, it is screened by the first screen 36 and the second screen 37. Material that meets the particle size requirements falls onto the conveyor belt 12. During the screening process, the dust collection component 4 uses the air pump 44 to suck away the dust generated during screening under negative pressure. At the same time, the third water supply pipe 64 and the second water supply pipe 62 of the dust suppression component 6 spray evenly along the conveyor line 1 to wet the surface of the conveyor belt. When the bauxite material falls onto the conveyor belt 12 after screening, it absorbs water and clumps together, preventing dust generation. The second water supply pipe 62 can continuously spray the surface of the bauxite during the conveying process to suppress dust. A V-shaped auxiliary roller group is set at the bottom of the conveyor belt 12 to support the conveyor belt 12 and prevent the conveyor belt 12 from shifting due to the water flow after spraying. It also carries the bauxite after absorbing water for conveying. Finally, the bauxite material is guided out through the discharge bin 13, achieving efficient, dust-free and low-loss conveying.

[0039] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
