Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in open-pit mines, specifically to a dust removal device. Background Technology

[0002] Open-pit mining is an important way to obtain mineral resources such as coal. As a core transfer node in the mining process, the crushing station undertakes the key task of transferring large pieces of material transported by mining trucks to belt conveyors. It is a core piece of equipment to ensure continuous and efficient production.

[0003] During operation, mining trucks load coal at the mining site and drive to the designated unloading area of ​​the crushing station. The trucks use a hydraulic system to lift the truck bed and unload the coal into the open hopper of the crushing station along the inclined direction of the truck bed.

[0004] Typically, there is a significant drop between the truck bed of a mining truck and the hopper of a crushing plant. During the coal's descent, collisions and friction generate substantial amounts of dust. Simultaneously, the induced airflow from the high-speed descent carries the dust rapidly outwards, causing a sharp increase in dust concentration in the work area. High dust concentrations directly obstruct the driver's view, increasing operational safety risks. Workers exposed to this environment for extended periods are prone to occupational diseases such as pneumoconiosis, severely damaging their health. Dust also adheres to the surfaces of precision equipment components, causing wear and corrosion, affecting normal equipment operation and shortening its lifespan, posing significant hazards to on-site workers, operational safety, and equipment stability.

The dust removal device includes: a hood, within which a conveying space is formed, and a connecting opening is formed on the side of the hood facing a mining truck, the connecting opening communicating with the conveying space; a telescopic gate assembly, comprising a telescopic member and a drive assembly, the telescopic member being disposed at the connecting opening, connected to the drive assembly, and extending and retracting in a predetermined direction under the drive assembly to change the passage area of ​​the connecting opening; and a baffle assembly, one end of which is connected to the telescopic member or the drive assembly and moves in a predetermined direction under the drive assembly, the other end extending away from the conveying space, the baffle assembly being rotatable relative to the hood, and the rotation axis of the baffle assembly being parallel to the telescopic member and perpendicular to the predetermined direction.

[0006] For example, the telescopic component includes a fixed plate and a first movable plate. The fixed plate is connected to the cover, the first movable plate is slidably connected to the cover, and the first movable plate is connected to a drive assembly and moves in a predetermined direction under the drive of the drive assembly.

[0007] For example, the first movable plate is located on the side of the fixed plate facing the conveying space.

[0008] For example, the first movable plate includes multiple plates connected sequentially along a predetermined direction, and each plate is slidably connected to the cover.

[0009] For example, the drive assembly includes a first drive member, a first lead screw drive member, a first slide rail and a first slider. The first slide rail is disposed on the outside of the cover and extends in a predetermined direction. The first slider is slidably connected to the first slide rail. The output end of the first drive member is connected to the first slider through the first lead screw drive member. The first slider is connected to the first moving plate and drives the first moving plate to move in a predetermined direction.

[0010] For example, the shield assembly includes a shield, a second movable plate, a second drive member, and a second lead screw drive member. The second movable plate is disposed on the side of the shield facing the mining truck. The output end of the second drive member is connected to the second movable plate through the second lead screw drive member. A second slide rail extending in a direction away from the conveying space is disposed on the side of the shield facing the second movable plate. A second slider slidably connected to the second slide rail is disposed on the side of the second movable plate facing the shield. The second drive member drives the second movable plate to slide relative to the shield through the second lead screw drive member.

[0012] For example, the dust removal device includes a control component, which is electrically connected to both the first drive component and the second drive component. An angle sensor is provided on the side of the second moving plate facing the mining truck, and the angle sensor is connected to the control component via 5G communication. And / or a distance sensor is provided on the side of the second moving plate facing the mining truck, and the distance sensor is connected to the control component via 5G communication.

[0013] For example, the cover includes a first cover and a second cover that communicates with the first cover. The communication opening is located at the end of the first cover away from the second cover, and the second cover is inclined downward in a direction away from the first cover.

[0014] For example, a plurality of spraying devices are provided on the inner side of the first cover, and at least two of the spraying devices have different spraying angles from each other.

Detailed Implementation

[0020] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0021] This utility model provides a dust removal device. This dust removal device can be used for dust removal during unloading of mining trucks in open-pit mine crushing plants. (Refer to the reference...) Figure 1 , Figure 2 and Figure 3 The dust removal device 2 includes a hood 4, a telescopic gate assembly 8, and a baffle assembly 13. A conveying space is formed inside the hood 4, and a connecting opening is formed on the side of the hood 4 facing the mining truck 1, connecting to the conveying space. One side of the hood 4 connects to the mining truck 1, and the other side can connect to the crushing station 3. When the mining truck 1 runs to the connecting opening, its bucket is lifted by a hydraulic system, dumping coal into the conveying space. After passing through the conveying space, the coal enters the crushing station 3. The mining truck 1 can partially enter the conveying space, that is, partially enter the hood 4. The telescopic gate assembly 8 includes a telescopic component and a drive assembly. The telescopic component is located at the connecting opening and is connected to the drive assembly. Under the drive of the drive assembly, the telescopic component extends and retracts in a predetermined direction to change the passage area of ​​the connecting opening. One end of the baffle assembly 13 is connected to the telescopic member or the drive assembly and moves in a predetermined direction under the drive of the drive assembly. The baffle assembly 13 can extend away from the conveying space at the other end. The baffle assembly 13 is rotatable relative to the cover 4. The rotation axis of the baffle assembly 13 is parallel to the telescopic member and perpendicular to the predetermined direction. That is, the telescopic gate assembly 8 can move to block the opening to different degrees, thereby changing the passage area of ​​the opening and preventing dust from escaping due to an excessively large opening. The baffle assembly 13 can rotate to fit more closely to the truck bed of the mining truck 1, further preventing dust from overflowing during unloading. Specifically, the baffle assembly 13 can rotate together with the tilt of the truck bed. The predetermined direction can be vertical, the straight line of the rotation axis is horizontal, and this straight line is parallel to the plane of the telescopic member. For example, the bottom of the telescopic member can be provided with a first hinge 10, which is hinged to the baffle assembly 13. Alternatively, the drive assembly may include a first hinge 10, which is hinged to the baffle assembly 13.

[0022] The working process of the dust removal device 2 can be as follows: the mining truck 1 drives to the connecting port, and the drive component drives the telescopic gate component 8 to extend and retract in a predetermined direction. By changing the passage area of ​​the connecting port, the connecting port is adapted to the unloading size of the mining truck 1's truck bed. At the same time, the baffle plate component 13 rotates to block and enclose the truck bed to a certain extent. Coal and other materials enter the conveying space through the connecting port and then enter the crushing station 3 to complete the unloading.

[0023] The dust removal device 2 provided in this application, through the setting of the telescopic gate assembly 8, flexibly adjusts the passage area of ​​the connecting opening. Combined with the rotating enclosure of the baffle assembly 13, it significantly reduces the channels for dust to escape to the surrounding area during coal descent, lowers the dust concentration in the work area, avoids the harm of high-concentration dust to the health of on-site workers, reduces the impact of dust obstructing the view of mining truck drivers, and lowers the probability of operational safety accidents. The relatively enclosed unloading environment can reduce dust pollution to the surrounding natural environment, prevent dust from adhering to the precision components of equipment such as the crushing station 3 and conveyors, thus avoiding wear and malfunctions and extending the service life of the equipment.

[0024] For example, in conjunction with reference Figure 2 and Figure 3 The telescopic component includes a fixed plate 801 and a first movable plate 802. The fixed plate 801 is connected to the cover 4, and the first movable plate 802 is slidably connected to the cover 4. The first movable plate 802 is connected to a drive assembly and moves along a predetermined direction under the drive of the drive assembly. The first movable plate 802 achieves relative displacement with the fixed plate 801 by sliding along the predetermined direction, and the overlapping area of ​​the two changes with the movement of the first movable plate 802. When the first movable plate 802 moves closer to the fixed plate 801, the overlapping area increases, and the passage area of ​​the connection port decreases accordingly; when the first movable plate 802 moves away from the fixed plate 801, the overlapping area decreases, and the passage area of ​​the connection port increases accordingly. This telescopic component design simplifies the adjustment process of the passage area of ​​the connection port. In subsequent maintenance, the first movable plate 802 can be maintained or replaced separately, resulting in lower maintenance costs for the equipment.

[0025] For example, in conjunction with reference Figure 2 and Figure 3 The first movable plate 802 is located on the side of the fixed plate 801 facing the conveying space. That is, the first movable plate 802 is located inside the fixed plate 801. This arrangement allows for easy cleaning of the outer surface of the first movable plate 802 even if it gets stuck due to dust or debris during sliding, without requiring disassembly of structural components, significantly reducing cleaning difficulty. Because the sliding connection is located inside and partially shielded by the fixed plate 801, the probability of direct dust intrusion is reduced, effectively preventing the first movable plate 802 from getting stuck due to dust accumulation.

[0026] For example, in conjunction with reference Figure 2 and Figure 3 The first movable plate 802 comprises multiple plates connected sequentially along a predetermined direction, each plate being slidably connected to the cover 4. This can be understood as the multiple plates being connected sequentially from top to bottom, with the topmost plate being the one closest to the fixed plate 801. A limiting structure can be provided between the topmost plate and the fixed plate 801 to prevent detachment. Similarly, limiting structures are also provided between adjacent plates. The first movable plate 802 has a segmented structure. This design allows the position of each plate to be adjusted according to actual operational needs, enabling the connection port to precisely adapt to different sizes of mining truck 1 buckets or unloading scenarios. The segmented design facilitates individual inspection and replacement of damaged plates, reducing equipment maintenance costs.

[0027] For example, in conjunction with reference Figure 2 and Figure 3 The driving assembly includes a first driving component, a first lead screw transmission component 5, a first slide rail 6, and a first slider 7. The first slide rail 6 is located on the outside of the cover 4 and extends along a predetermined direction. The first slider 7 is slidably connected to the first slide rail 6. The output end of the first driving component is connected to the first slider 7 via the first lead screw transmission component 5. The first slider 7 is connected to the first moving plate 802 and drives the first moving plate 802 to move along the predetermined direction. Specifically, there can be two first slide rails 6, and the first slider 7 is slidably connected to both first slide rails 6. During operation, the first driving component is activated, driving the first slider 7 to slide smoothly along the first slide rail 6 via the first lead screw transmission component 5. The first slider 7 simultaneously pulls the first moving plate 802 to move along the predetermined direction, thereby adjusting the passage area of ​​the connecting port. The first slide rail 6 provides guidance for the movement of the first slider 7 and the first moving plate 802, ensuring that the first moving plate 802 can slide smoothly along the predetermined direction, avoiding deviation, and improving the accuracy of adjusting the passage area of ​​the connecting port. The lead screw drive system offers high transmission precision and large torque, ensuring smooth and uniform movement of the first moving plate 802. It also provides more precise control over the extension and retraction stroke, guaranteeing the accuracy and stability of the dust removal device 2. For example, a connecting plate 9 can be provided on the first slider 7, allowing the first moving plate 802 to be connected to the first slider 7 via the connecting plate 9.

[0028] For example, in conjunction with reference Figure 2 , Figure 3 and Figure 4The baffle assembly 13 includes a baffle 1301, a second movable plate 1302, a second drive member, and a second lead screw transmission member 1304. The second movable plate 1302 is disposed on the side of the baffle 1301 facing the mining truck 1. The output end of the second drive member is connected to the second movable plate 1302 through the second lead screw transmission member 1304. A second slide rail 1303 extending away from the conveying space is disposed on the side of the baffle 1301 facing the second movable plate 1302. A second slider 1306 slidably connected to the second slide rail 1303 is disposed on the side of the second movable plate 1302 facing the baffle 1301. The second drive member drives the second movable plate 1302 to slide relative to the baffle 1301 through the second lead screw transmission member 1304. The overall shielding area of ​​the shielding plate assembly 13 can be flexibly changed by moving the second movable plate 1302 relative to the shielding plate 1301. Specifically, when the shielding area needs to be expanded, the second movable plate 1302 extends along the second slide rail 1303 in a direction away from the conveying space, and retracts in the opposite direction, quickly adapting to different sizes of the mining truck 1's cargo bed and ensuring a good shielding and sealing effect. The second slide rail 1303 provides guidance for the movement of the second movable plate 1302, ensuring that it can slide smoothly in a direction away from or near the conveying space, avoiding deviation or jamming. The second driving member and the second lead screw transmission member 1304 drive the second movable plate 1302 to move along the second slide rail 1303. The overall transmission logic is simple and can achieve rapid adjustment of the shielding area. It can be understood that the direction away from the conveying space can be multiple directions, which can be perpendicular to the predetermined direction or not, as long as it gradually moves away from a certain point in the conveying space during the movement.

[0029] For example, in conjunction with reference Figure 2 , Figure 3 and Figure 4A telescopic rod 12 is provided on the side of the shield 1301 opposite to the second movable plate 1302. One end of the telescopic rod 12 is connected to the first slider 7, and the other end is connected to the shield 1301. Specifically, the telescopic rod 12 can be a telescopic hydraulic cylinder. During operation, the telescopic rod 12 generates a pushing and pulling force through its own telescopic movement, pulling the shield 1301 to rotate around its hinge point. By controlling the telescopic amount of the telescopic rod 12, the tilt angle of the shield 1301 can be flexibly adjusted, so that the shield assembly 13 better fits the truck bed of the mining truck 1. This configuration has a simple and direct transmission logic, a fast response speed for angle adjustment, and can quickly adapt to the truck beds of mining trucks 1 of different sizes and shapes. Specifically, the first slider 7 can be provided with a first hinge lug 10 and a second hinge lug 11, and the shield 1301 is hinged to the first slider 7 through the first hinge lug 10 and the second hinge lug 11. Furthermore, a fourth hinge 1307 can be provided at the end of the shielding plate 1301 near the conveying space, through which it is hinged to the first slider 7. Exemplarily, a third hinge 1305 can be provided at the end of the shielding plate 1301 away from the conveying space, through which it is connected to the telescopic rod 12. Alternatively, in another embodiment, the first hinge 10 and the second hinge 11 can both be provided at the bottom of the first moving plate 802, and the shielding plate 1301 is connected to the first moving plate 802 through the first hinge 10 and the second hinge 11. Exemplarily, a connecting plate 9 can be provided on the first slider 7, and the shielding plate 1301 can be connected to the first slider 7 through the connecting plate 9.

[0030] For example, in conjunction with reference Figure 2 , Figure 3 and Figure 4The dust removal device 2 includes a control component, which is electrically connected to both the first and second driving components. An angle sensor is installed on the side of the second moving plate 1302 facing the mining truck 1, and the angle sensor is connected to the control component via 5G communication. And / or, a distance sensor is installed on the side of the second moving plate 1302 facing the mining truck 1, and the distance sensor is connected to the control component via 5G communication. The angle sensor can monitor the tilt angle of the second moving plate 1302 and the shielding plate 1301 in real time, and the distance sensor can accurately monitor the distance between the second moving plate 1302 and the truck bed of the mining truck 1. For example, both the angle sensor and the distance sensor can be installed on the side of the second moving plate 1302 away from the conveying space. This arrangement allows for accurate sensing and feedback of the working status of the shielding plate assembly 13, enabling corresponding adjustments based on the detection data to ensure optimal shielding and sealing effects. 5G communication technology ensures low latency and high stability in data transmission. Even in the complex electromagnetic environment and dust interference of open-pit mines, it can prevent signal interruption or data distortion, allowing control components to quickly adjust relevant parts based on detection data, ensuring optimal shielding and sealing effects. Remote data interaction and status monitoring via 5G communication technology eliminate the need for close-range manual operation, improving operational safety and management efficiency.

[0031] Combined with reference Figure 1 , Figure 2 and Figure 3 The enclosure 4 includes a first enclosure 4 and a second enclosure 4 connected to the first enclosure 4. The connection port is located at the end of the first enclosure 4 away from the second enclosure 4. The second enclosure 4 is inclined downwards in the direction away from the first enclosure 4. The first enclosure 4 is connected to the mining truck 1 through the connection port, and the end of the second enclosure 4 away from the first enclosure 4 is connected to the crushing station 3. The connection port of the first enclosure 4 to the mining truck 1 provides a stable enclosed space for the unloading process. The downwardly inclined structure of the second enclosure 4 can conform to the trajectory of the coal falling under its own weight, ensuring dust prevention and anti-escape effects during the falling process. The structural design is more reasonable.

[0032] For example, in conjunction with reference Figure 2 and Figure 3The first hood 4 has multiple spraying devices 402 arranged inside, with at least two of the spraying devices 402 having different spraying angles. Further, the first hood 4 can have multiple support frames 401, and the spraying devices 402 can be mounted on the support frames 401. Even further, there can be multiple support frames 401, and each support frame 401 can have multiple spraying devices 402. The spraying angles of the spraying devices 402 on a single support frame 401 can be the same or different. The multi-angle spraying devices 402 can provide comprehensive coverage of the conveying space within the first hood 4, avoiding blind spots in dust removal and improving dust suppression efficiency. The number of spraying devices 402 that can be activated can be flexibly adjusted according to the actual dust concentration, balancing dust removal efficiency and media conservation. For example, multiple spraying devices 402 can be arranged on the inner walls of opposite sides of the first hood 4.
