Description

Technical Field

[0001] This utility model relates to the field of coal transportation technology, specifically to a dust suppression device for coal transportation. Background Technology

[0002] In complex industrial sites, coal materials typically need to be transported through a relay transportation system consisting of multiple conveyor belts. The transfer points between different conveyor belts are the key links in the entire transportation process and also the main sources of dust generation.

[0003] In related technologies, the dust generated at the transfer point of two conveyor belts with a height difference not only causes intangible losses of precious coal resources, but also poses a serious threat to the working environment and the surrounding ecological environment. Inhalation of the dust by on-site operators can cause serious occupational health problems such as pneumoconiosis; suspended coal dust poses an explosion risk, creating a significant hazard to safe production. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of this utility model propose a dust suppression device for coal transportation, which improves the safety and conveying efficiency during coal transportation.

[0020] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1 and Figure 2 As shown, the dust suppression device for coal transportation in this embodiment of the present invention includes: a frame 1 and a dust collection component 2.

[0022] The frame 1 has a dust removal chamber 11, and the end of the conveyor 100 is placed inside the dust removal chamber 11. The dust collection assembly 2 is connected to the frame 1. The dust collection assembly 2 includes a dust collection drive and a first dust collection component 21. The first dust collection component 21 is located above the conveyor 100 and has a first dust collection port 211. The first dust collection port 211 is arranged facing the conveyor 100, and the cross-sectional area of ​​the first dust collection port 211 gradually decreases in the direction from the conveyor 100 to the first dust collection component 21. The dust collection drive is connected to the first dust collection component 21 to provide dust collection power to the first dust collection component 21.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the frame 1 can be a closed or semi-closed structure, and the space enclosed by the side walls of the frame 1 is the dust collection chamber 11. The end of the conveyor 100 is placed inside the dust collection chamber 11. That is, when the conveyor 100 needs to turn or when there is a misalignment in the conveyor, when the coal on the conveyor 100 at the higher position falls onto the conveyor 100 at the lower position, dust is easily generated. Therefore, placing the end of the conveyor 100 inside the dust collection chamber 11 prevents the dust from spreading to the surroundings, thereby effectively controlling the dust generated when the coal is transferred from one conveyor belt to another.

[0024] Understandably, the suction drive unit can be one or more fans or other types of suction power devices responsible for generating suction. The suction drive unit is connected to the first suction component 21 via piping or directly, providing the necessary suction power to the suction component. The first suction component 21 is located above the conveyor 100, and its main function is to capture and guide dust flow towards the suction drive unit. The first suction component 21 has a first suction port 211, which is arranged facing the conveyor 100 to capture dust generated from the discharge point of the conveyor 100.

[0025] Preferably, the cross-sectional area of ​​the first suction port 211 gradually decreases from bottom to top, meaning the first suction port 211 has a structure similar to a "funnel". This helps to concentrate airflow and improve suction efficiency, as the airflow velocity increases in the gradually narrowing channel, allowing for more effective capture and suction of dust. Furthermore, the sidewalls of the first suction port 211 prevent dust adhesion. After prolonged use, dust easily adheres to the sidewalls of the first suction port 211; however, because the sidewalls are inclined, the dust automatically falls off after accumulating to a certain extent.

[0026] Therefore, the coal transportation dust suppression device of this embodiment, through the action of the dust collection component 2, not only reduces the dust concentration in the workplace and improves the working environment for operators, but also reduces the concentration of suspended coal dust, lowers the risk of coal dust explosion, and improves production safety. Furthermore, since the cross-sectional area of ​​the first dust collection port 211 gradually decreases in the direction from the conveyor 100 to the dust collection component, it helps to increase the airflow velocity, thereby more effectively capturing dust.

[0027] In some embodiments, the frame 1 has a plurality of windows 12 that communicate with the dust removal chamber 11. The plurality of windows 12 are arranged circumferentially at intervals along the center line of the frame 1, and a portion of the conveyor 100 is placed in the dust removal chamber 11 through the windows 12.

[0028] Specifically, such as Figure 1 and Figure 2 As shown, since the windows 12 are arranged at intervals along the circumference, the conveyor 100 can be introduced at different positions. In other words, different windows 12 can be used in combination depending on the position of the conveyor 100. That is, multiple windows 12 make it more convenient to adjust the position of the conveyor 100, which can be adjusted according to actual working needs to adapt to different coal transportation requirements.

[0029] Understandably, the design of window 12 also enhances the structural stability of frame 1. The distribution and spacing of windows 12 effectively disperse and reduce the structural load caused by dust suction. Furthermore, in case of an emergency, operators can quickly approach conveyor 100 from multiple directions to address the problem promptly, improving operational safety.

[0030] In some embodiments, the dust suppression device for coal transportation in this utility model further includes a shielding plate 3, which is detachably connected to the frame 1 and is used to shield the window 12.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the baffle 3 can be detachably connected to the frame 1 by means of bolt connection, snap-fit ​​or plug-in connection, so that the size of the window 12 can be adjusted by adjusting the position of the baffle 3, so as to be suitable for conveyors 100 at different positions and heights.

[0032] Understandably, when it is necessary to operate or maintain the conveyor 100, the operator can quickly remove the shield 3 to perform the necessary work, and then reinstall the shield 3 after the work is completed. A rubber gasket can also be installed between the shield 3 and the frame 1 to ensure good sealing and prevent dust leakage.

[0033] In other words, the main function of the baffle 3 is to block the window 12 to prevent dust leakage or foreign objects from entering the dust collection chamber 11 when operation or maintenance is not required through the window 12. This helps maintain the airtightness of the dust collection chamber 11 and ensures the dust collection effect. The detachable connection design between the baffle 3 and the frame 1 allows operators to quickly install or remove the baffle 3 as needed. This design improves the system's flexibility and ease of operation.

[0034] In some embodiments, there are multiple shielding plates 3, and multiple shielding plates 3 are arranged corresponding to a window 12.

[0035] It is understandable that, such as Figure 1 and Figure 2 As shown, a window 12 is located on one side of the frame 1. Since the conveyor 100 is mostly located in the middle of the frame 1, the remaining space of the window 12 needs to be covered. That is, after the conveyor 100 is placed, multiple baffles 3 can be used to cover the exposed window 12 above or below the conveyor 100, thereby preventing dust in the dust removal chamber 11 from spreading to the outside.

[0036] In other words, the design of multiple baffles 3 allows each baffle 3 to operate independently. This modular design facilitates the installation, disassembly, and replacement of individual panels, improving maintenance efficiency. Since each window 12 has a corresponding baffle 3, a single baffle 3 can be adjusted or removed as needed without affecting the status of other baffles 3, enhancing operational flexibility. For windows 12 of different sizes, the number and size of the baffles 3 can be adjusted to ensure a more precise match between the baffles 3 and the window 12.

[0037] In some embodiments, there is a gap between the baffle plate 3 and the conveyor 100 in the height direction of the frame 1.

[0038] Understandably, by adjusting the position of the baffle plate 3, the size of the gap needs to be determined based on the operating characteristics and maintenance requirements of the conveyor 100, so as to ensure sufficient operating space while avoiding excessive gaps that could lead to dust leakage.

[0039] In other words, because there is a gap between the baffle plate 3 and the conveyor 100, the conveyor 100 will not directly contact the baffle plate 3 during operation, thereby reducing friction and potential mechanical damage. The gap also makes it easier for operators to access the conveyor 100 for routine inspections and maintenance.

[0040] In some embodiments, the vacuuming assembly 2 further includes a second vacuuming component 22, which is connected to the vacuuming drive component, is placed in the dust removal chamber 11, and is movable relative to the frame 1.

[0041] It is understandable that, such as Figure 1 and Figure 2 As shown, the second suction component 22 can be connected to the suction drive component via a specific connecting device, or the second suction component 22 can be connected to the suction drive component via a flexible pipe, and the two are fixedly connected by a bendable metal strip to ensure that effective suction capability is maintained during movement. The movement of the second suction component 22 can be achieved manually or automatically, for example, by using pulleys, guide rails, or motor-driven devices to adjust its position.

[0042] In other words, the second dust-collecting component 22 is connected to the dust-collecting drive component and is placed inside the dust collection chamber 11. It can move relative to the frame 1 as needed to adapt to different working conditions or maintenance requirements. The movable design of the second dust-collecting component 22 allows it to be adjusted accordingly based on changes in the position of the coal on the conveyor belt, ensuring more effective capture and removal of dust.

[0043] In some embodiments, the vacuuming assembly 2 further includes a connecting member 23, the first end of which is connected to the second vacuuming assembly 22, the second end of which is connected to the frame 1, and the connecting member 23 is bendable relative to the frame 1.

[0044] It is understandable that, such as Figure 1 and Figure 2 As shown, the connecting component 23 is typically made of a flexible material (such as a bendable metal strip), such as a metal tube (bendable), a high-temperature resistant plastic tube, or a specially designed hose, to ensure that it can be bent under different conditions without breaking or leaking. It should be noted that the design of the connecting component 23 should take into account its bending radius and the number of bends to ensure that it maintains good performance after multiple bends.

[0045] In other words, the flexibility of the connecting component 23 allows the entire vacuum assembly 2 to adapt to more complex spatial environments, especially when the space within the dust collection chamber 11 is limited or irregularly shaped. Because the connecting component 23 is flexible, it allows for more flexibly avoiding other equipment and structures during installation and adjustment of the vacuum assembly 2, reducing installation difficulty. The flexibility of the connecting component 23 also allows the second vacuum component 22 to move to the optimal position within the dust collection chamber 11, thereby more effectively capturing dust and improving dust removal efficiency.

[0046] In some embodiments, the second suction component 22 has a second suction port 221, the cross-sectional area of ​​which gradually decreases along the gas flow direction.

[0047] It is understandable that, such as Figure 1 and Figure 2 As shown, the second suction port 221 is typically designed with a "trumpet-shaped" structure, with its cross-sectional area gradually decreasing along the gas flow direction. As the cross-sectional area of ​​the suction port gradually decreases, the airflow velocity increases, creating a centripetal flow that helps concentrate the airflow and improve dust capture. Because the airflow flows within a gradually narrowing channel, airflow separation and vortex formation are reduced, thereby minimizing energy loss. This design of the suction port helps optimize the airflow distribution within the suction components, resulting in more uniform airflow and improving the stability and efficiency of the entire suction system.

[0048] In addition, the inclined sidewall of the second suction port 221 can reduce the adhesion and accumulation of dust, ensuring the suction effect.

[0049] In some embodiments, the dust suppression device for coal transportation of this utility model further includes a collection component 4, which is disposed in the dust removal chamber 11 and located below the conveyor 100. The collection component 4 has a collection chamber 41, which is connected to the dust removal chamber 11.

[0050] Specifically, such as Figure 1 and Figure 2 As shown, the collecting component 4 is installed below the conveyor 100 and inside the dust removal chamber 11. The collecting chamber 41 is connected to the dust removal chamber 11 to collect the dust captured inside the dust removal chamber 11, thereby reducing the impact of dust on the environment. The collecting chamber 41 in the collecting component 4 is used to temporarily store the dust, which can then be recycled and processed, such as for reuse or safe disposal.

[0051] Alternatively, the collecting component 4 may be one or more dust collecting bags, containers, or boxes. The collecting chamber 41 may be designed with an emptying mechanism, such as a vibrator, compressed air jet, or automatic dust removal system, to facilitate periodic emptying of the collected dust.

[0052] In other words, the collection chamber 41 in the collection component 4 is used to temporarily store dust, which can then be recycled and processed, such as for reuse or safe disposal.

[0053] In some embodiments, in the direction from the conveyor 100 to the collecting member 4, the cross-sectional area of ​​the collecting cavity 41 gradually decreases, and the wall of the collecting cavity 41 is smoothly connected to the wall of the dust removal cavity 11.

[0054] It is understandable that, such as Figure 1 and Figure 2 As shown, the collecting chamber 41 is typically designed with a "trumpet-shaped" structure, with its cross-sectional area gradually decreasing from top to bottom. The wall of the collecting chamber 41 is smoothly connected to the wall of the dust removal chamber 11, which can reduce the accumulation and blockage of dust at the connection point and ensure smooth airflow inside the dust removal chamber 11.

[0055] Preferably, the connection between the collecting chamber 41 and the dust removal chamber 11 can be made by means of bonding to ensure good sealing and prevent leakage of dust and gas.
