Description

Technical Field

[0001] This utility model relates to the field of dust removal technology in mining, and in particular to a dry fog dust suppression mechanism for mining crushing. Background Technology

[0002] Crushing in mines is a crucial step in mineral resource processing, primarily used to break large ore blocks into smaller particles that meet the requirements of subsequent processing. During crushing, the intense collisions and friction of materials generate large amounts of dust, which not only seriously affects the working environment and the health of operators but also potentially poses safety hazards such as dust explosions. Therefore, employing efficient dust suppression measures is essential in mine crushing operations. Dry fog dust suppression technology, due to its water-saving, high-efficiency, and rapid-response characteristics, is widely used in dust control for various crushing equipment and conveying systems.

[0003] Utility model patent CN219929057U discloses a dry fog dust suppression mechanism for mining crushing. It uses a motor to drive fan blades to generate airflow, guiding atomized water vapor to fully contact the dust. An adjustable support structure allows for installation on conveyor belts of different widths, thus improving the device's applicability and dust suppression efficiency. However, in actual operation, it was found that the two air sources of this device are horizontally and oppositely positioned. This causes the airflow to collide and merge, forming an outward-repelling airflow field. This hinders the atomized water vapor from sinking downwards above the dust source, reducing the effective combination rate of water mist and dust, and thus affecting the overall dust suppression effect. Furthermore, this airflow interference also causes some droplets to disperse into non-target areas, wasting water resources and polluting surrounding equipment.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a dry fog dust suppression mechanism for mine crushing. This new device should significantly improve the directional delivery efficiency and dust capture capability of atomized water vapor, possess excellent airflow organization capabilities and adaptability to multiple operating conditions, better meet the needs of modern and green mine production, and provide strong support for clean operations and safe production in the mine crushing process. Summary of the Invention

[0005] The purpose of this invention is to provide a dry fog dust suppression mechanism for mining crushing, which solves the problem in the prior art where two air sources are set horizontally and oppositely, causing the airflows to collide and merge and form an outward repulsive airflow field, which in turn hinders the atomized water vapor from sinking downwards to the dust source, reduces the effective combination rate of water mist and dust, and thus affects the overall dust suppression effect.

[0006] To achieve the above objectives, this utility model provides a dry fog dust suppression mechanism for mining crushing, including a top plate and two mounting frames symmetrically arranged at the bottom of the top plate, wherein the mounting frames are connected to the bottom of the top plate through a support frame;

[0007] The top plate has mounting frames installed at an angle on both sides, and each of the two mounting frames has a fan installed inside. The two mounting frames are detachably connected to the top of the top plate through two connecting structures.

[0008] A spray module is installed at the bottom of the top plate, and a liquid delivery pipe connected to the spray module is provided at the top of the top plate.

[0009] The top plate has two symmetrical adjustment slots on both sides, and the top of the support frame has adjustment rods that slide in cooperation with the adjustment slots on both sides. One side of the adjustment rod is provided with a positioning structure that can be detachably cooperated with the inner wall of the adjustment slot.

[0010] The connecting structure includes a mounting rod and two connecting brackets. The mounting rod is fixedly connected to the top of the top plate with bolts. One side of the connecting bracket is connected to the side wall of the mounting frame, and the other end is connected to the end of the mounting rod.

[0011] The positioning structure includes a positioning screw with one end threaded through the adjusting rod, and the inner wall of the adjusting groove is provided with a number of positioning holes that are adapted to the positioning screw.

[0012] Several crossbars are provided between the two mounting rods, and the two ends of the crossbars are respectively connected to the adjacent mounting rods.

[0013] The mounting bracket has several fixing screws on one side, with one end threaded through the mounting bracket, and one end of the fixing screws is connected to a handle.

[0014] This utility model discloses a dry fog dust suppression mechanism for mining crushing. By placing the fan inside an inclined mounting frame, it overcomes the airflow interference problem caused by the horizontal relative arrangement of the original air sources, effectively avoiding the exhaust wind field formed by airflow merging. This significantly improves the directional delivery efficiency of water mist, allowing the atomized water vapor to accurately cover the dust source, improving dust capture efficiency and settling speed, thereby enhancing the overall dust suppression effect. Secondly, the inclined fan layout combined with the reasonable configuration of the spray module optimizes the airflow organization, enhances the binding rate of water mist and dust, reduces waste caused by water mist dispersion and pollution to surrounding equipment, and improves water resource utilization and environmental performance. Thirdly, the detachable connection between the mounting frame and the top plate through the connecting structure improves the assembly flexibility and maintenance convenience of the device, making it suitable for rapid deployment and replacement under different working conditions.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments 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, but should not be construed as limiting the present invention. Example

[0023] Please see Figure 1-5 As shown, a dry fog dust suppression mechanism for mining crushing in this embodiment includes a top plate 3 and two mounting frames 1 symmetrically arranged at the bottom of the top plate 3. The mounting frames 1 are connected to the bottom of the top plate 3 through a support frame 2.

[0024] The top plate 3 is inclined on both sides and has mounting frames 5. Fans 4 are installed inside the two mounting frames 5. The two mounting frames 5 are detachably connected to the top of the top plate 3 through two connecting structures.

[0025] A spray module 9 is installed at the bottom of the top plate 3, and a liquid delivery pipe 6 connected to the spray module 9 is provided at the top of the top plate 3.

[0026] The working process is as follows: The device uses symmetrically arranged mounting frames 5 on both sides of the top plate 3 to cooperate with the fans 4, so that the two fans 4 are arranged at an inclined angle above the dust diffusion area. When the equipment is running, the fans 4 start and generate high-speed airflow. The airflow is guided downward along the direction of the mounting frames 5 to form a stable directional air curtain, avoiding the mutual repulsion problem of airflow caused by the traditional horizontally opposite air sources. At the same time, a spray module 9 is installed at the bottom of the top plate 3, and a water supply structure connected to it is provided at the top. Under the guidance of the airflow generated by the fans 4, the water mist sprayed by the spray module 9 is efficiently transported to the dust generation area, and after fully contacting, adhering and condensing with the dust, it quickly settles, thereby achieving efficient dust suppression. In addition, the two mounting frames 5 are detachably connected to the top of the top plate 3 through a connecting structure, making the entire device easy to disassemble and maintain; the bottom of the top plate 3 is connected to the mounting frame 1 through the support frame 2, and the mounting frame 1 is fixed to the external equipment to ensure that the entire dust suppression mechanism is stably installed near the crushing operation area. Example

[0027] Please see Figure 1-5 As shown in this embodiment, a dry fog dust suppression mechanism for mining crushing has two symmetrical adjustment slots 10 on both sides of the top plate 3. Adjustment rods 7, which slide in conjunction with the adjustment slots 10, are fixedly connected to both sides of the top of the support frame 2. One side of each adjustment rod 7 has a positioning structure that detachably engages with the inner wall of the adjustment slot 10. Specifically, by using the adjustment slots 10, adjustment rods 7, and positioning screws 8, when the height or tilt angle of the top plate 3 needs adjustment, the operator can slide the adjustment rods 7 along the adjustment slots 10, causing the support frame 2 to drive the mounting frame 1 for fine-tuning. Then, the positioning screws 8 are tightened to insert them into the corresponding positioning holes 11 for fixation. This structure allows for flexible adjustment of the overall installation posture of the dust suppression mechanism, achieving the effect of adapting to different crushing equipment layouts and improving the applicability of lifting devices.

[0028] The positioning structure includes a positioning screw 8 with one end threaded through the adjusting rod 7. The inner wall of the adjusting groove 10 is provided with several positioning holes 11 that are adapted to the positioning screw 8. Specifically, through the setting of the crossbar 14, two mounting rods 13 are connected to its two ends respectively. During the operation of the fan 4, the crossbar 14 effectively enhances the lateral connection rigidity between the two mounting frames 5, preventing structural deformation or displacement caused by airflow impact, thereby achieving the effect of enhancing the overall structural stability and vibration resistance. Example

[0029] Please see Figure 1-5As shown in this embodiment, a dry fog dust suppression mechanism for mining crushing includes a connecting structure comprising a mounting rod 13 and two connecting brackets 12. The mounting rod 13 is bolted to the top of the top plate 3. One side of the connecting bracket 12 is connected to the side wall of the mounting frame 5, and the other end is connected to the end of the mounting rod 13. Specifically, through the arrangement of the mounting rod 13 and the connecting brackets 12, the mounting rod 13 is bolted to the top plate 3, and one end of the connecting bracket 12 is connected to the mounting rod 13, while the other end is fixed to the side wall of the mounting frame 5, thus forming a stable connection and support system. This structure not only enhances the connection strength between the fan 4 and the top plate 3, but also improves the stability of the entire device during operation, achieving the technical effects of improving structural load-bearing capacity and preventing loosening due to vibration.

[0030] Several crossbars 14 are provided between the two mounting rods 13. The two ends of each crossbar 14 are connected to the adjacent mounting rod 13. Specifically, through the cooperation of the positioning screw 8 and the positioning hole 11, the positioning screw 8 on the adjusting rod 7 can be inserted into different positions of the positioning hole 11 according to actual installation requirements, achieving multi-level precise positioning. This design allows the device to quickly adjust its installation state according to different working conditions, thereby improving assembly accuracy and ease of operation.

[0031] One side of the mounting frame 1 is equipped with several fixing screws, one end of which is threaded through the mounting frame 1. A handle is connected to one end of each fixing screw. Specifically, through the arrangement of the fixing screws and handles, multiple fixing screws are provided on one side of the mounting frame 1, with one end penetrating the mounting frame 1 and contacting the surface of the external equipment, and the other end connected to the handle for tightening. This structure facilitates the secure fixing of the entire dust suppression mechanism around the crushing equipment, preventing displacement or detachment during operation, thus enhancing the stability of the device installation and ensuring on-site operational safety.

[0032] This utility model discloses a dry fog dust suppression mechanism for mining crushing, with the following complete working process: The device uses symmetrically arranged mounting frames 5 on both sides of the top plate 3, allowing two fans 4 to be tilted above the dust diffusion area. During operation, the fans 4 generate high-speed airflow, which is guided downwards along the mounting frames 5, forming a stable directional air curtain. This effectively avoids the mutual repulsion problem caused by traditional horizontally opposed air sources. Simultaneously, a spray module 9 is installed at the bottom of the top plate 3, with a water supply structure connected to it at the top. Driven by the airflow generated by the fans 4, the water mist sprayed from the spray module 9 is efficiently transported to the dust generation area, where it fully contacts, adheres to, condenses, and quickly settles after contact with the dust, achieving efficient dust suppression. In addition, the two mounting frames 5 are detachably connected to the top of the top plate 3 via a connecting structure. The connecting structure includes a mounting rod 13 and a connecting bracket 12. The mounting rod 13 is fixed to the top plate 3 by bolts. One end of the connecting bracket 12 is connected to the mounting rod 13, and the other end is connected to the side wall of the mounting frame 5, thus forming a stable support system. At the same time, a crossbar 14 is provided between the two mounting rods 13 to enhance the lateral rigidity of the overall structure and prevent deformation or displacement caused by airflow impact.

[0033] The top plate 3 is connected to the mounting frame 1 via a support frame 2 at its bottom. The mounting frame 1 is used to fix the entire device to the external equipment. To improve installation adaptability, adjustment grooves 10 are provided on both sides of the top plate 3. The top of the support frame 2 is provided with an adjustment rod 7 that slides with it. One side of the adjustment rod 7 is provided with a positioning structure, including a positioning screw 8 that passes through the adjustment rod 7 and multiple positioning holes 11 on the inner wall of the adjustment groove 10. The operator can slide the adjustment rod 7 along the adjustment groove 10 to adjust the height or angle of the top plate 3 according to actual needs, and then tighten the positioning screw 8 to insert it into the corresponding positioning hole 11 to complete the fixation. In order to further enhance the connection stability between the mounting frame 1 and the external equipment, multiple fixing screws are provided on one side of the mounting frame 1. One end of the fixing screw passes through the mounting frame 1 and is in contact with the surface of the external equipment, and the other end is connected to a handle for easy tightening and fixing on site.

[0034] Compared with existing technologies, this dust suppression mechanism has the following significant advantages: First, by placing the fan 4 inside the inclined mounting frame 5, the problem of airflow interference caused by the horizontal relative arrangement of the original air sources is changed, effectively avoiding the exhaust wind field formed by airflow fusion, significantly improving the directional delivery efficiency of water mist, enabling atomized water vapor to accurately cover the dust source, improving dust capture efficiency and settling speed, and thus enhancing the overall dust suppression effect. Second, the inclined fan layout combined with the reasonable configuration of the spray module 9 optimizes the airflow organization, enhances the combination rate of water mist and dust, reduces waste caused by water mist dispersion and pollution to surrounding equipment, and improves water resource utilization and environmental performance. Third, the connection structure composed of the mounting rod 13, connecting bracket 12, and crossbar 14 achieves a stable connection between the fan 4 and the top plate 3, which not only enhances the structural load-bearing capacity but also improves the vibration resistance, preventing loosening and falling off due to vibration during operation. Furthermore, the coordinated arrangement of the adjusting groove 10, adjusting rod 7, and positioning screw 8 allows for flexible adjustment of the height and angle of the top plate 3, meeting the installation requirements of different crushing equipment and improving the versatility and adaptability of the device. Finally, the design of the fixing screw and handle on the mounting frame 1 ensures that the device is firmly fixed around the crushing equipment, preventing displacement or detachment during operation and ensuring on-site operational safety. In summary, this mine crushing dry fog dust suppression mechanism, through the synergistic effect of components such as the top plate 3, mounting frame 1, support frame 2, mounting frame 5, fan 4, connecting structure, spray module 9, adjusting groove 10, adjusting rod 7, positioning screw 8, positioning hole 11, mounting rod 13, connecting bracket 12, crossbar 14, fixing screw, and handle, effectively solves the problem of low dust suppression efficiency caused by unreasonable air source layout in existing technologies. It also possesses good structural stability, adjustment flexibility, and ease of installation, fully meeting the actual needs of modern mines for efficient, energy-saving, and green dust control.
