[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0046] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a dust reduction device, which includes a foaming component 10, an air supply pipe 20, a water supply pipe 30 and a liquid infusion pipe 40. The foaming component 10 has a shell 11 and a foaming structure 12, the shell 11 has a foaming chamber 111 and a foam outlet, and the foaming structure 12 is rotatably arranged in the foaming chamber 111. The air supply pipe 20 is connected to the foaming chamber 111. A first magnetizing device 31 is provided on the water supply pipe 30, and the water supply pipe 30 is connected to the foaming chamber 111. The first magnetizing device 31 is used to magnetize water. A second magnetizing device 41 is provided on the liquid infusion pipe 40, and the liquid infusion pipe 40 is connected to the foaming chamber 111. The liquid infusion pipe 40 is used to transport foaming liquid, and the second magnetizing device 41 is used to magnetize the foaming liquid.

[0047] By applying the technical solution of the present application, water will pass through the first magnetizing device 31 during transportation in the water pipeline 30, and the first magnetizing device 31 will magnetize the water. The foaming liquid will pass through the second magnetizing device 41 in the liquid pipeline 40, and the second magnetizing device 41 can magnetize the foaming liquid. Wind, water and foaming liquid form magnetized foam in the shell 11, and the magnetized foam is discharged through the foam outlet. Such a setting is convenient for operation, and there is no need for staff to inject water into the coal seam, which reduces the labor intensity of the staff. In addition, the magnetized foam has a higher ability to absorb dust, which can reduce the consumption of water resources and ensure the dust reduction effect of the dust reduction device. During the rotation process, the foaming structure 12 can avoid the accumulation of impurities, thereby preventing impurities from being blocked in the foaming component 10. At the same time, the water in the water pipeline 30 can flush the foaming component 10, further reducing the probability of blockage.

[0048] The housing 11 has a fluid inlet 112 .

[0049] The dust reduction device also includes a mixing structure 50, which has a mixing chamber 51, an air inlet 52, a water inlet 53, a liquid inlet 54 and a fluid outlet 55. The air inlet 52, the water inlet 53, the liquid inlet 54 and the fluid outlet 55 are all connected to the mixing chamber 51, the air supply pipe 20 is connected to the air inlet 52, the water supply pipe 30 is connected to the water inlet 53, the liquid supply pipe 40 is connected to the liquid inlet 54, and the fluid outlet 55 is connected to the fluid inlet 112.

[0050] Such a setting can ensure that the wind, water and foaming liquid can be fully mixed in the mixing chamber 51 before entering the foaming component 10 to form a uniform mixed fluid, providing a good foundation for the subsequent foaming process and improving the foam generation quality and dust reduction efficiency.

[0051] Furthermore, different fluids can be easily accessed and controlled through the separate air inlet 52, water inlet 53 and liquid inlet 54, so that operators can more intuitively adjust and manage the dust suppression device, reducing operational difficulty and error rate.

[0052] At the same time, the fluid outlet 55 of the mixing structure 50 is directly connected to the fluid inlet 112 of the foaming component 10, avoiding precipitation or blockage of the mixed fluid during transmission, and ensuring smooth fluid transmission and continuity of equipment operation.

[0053] Specifically, the foaming component 10 further includes a rotating shaft and a driving member. The rotating shaft is rotatably disposed in the foaming cavity 111 . The driving member is drivingly connected to the rotating shaft. The foaming structure 12 is detachably disposed on the rotating shaft.

[0054] Such an arrangement facilitates driving the foaming structure 12 to rotate. At the same time, the foaming structure 12 promotes gas-liquid mixing during the rotation process, thereby generating richer and more stable foam and improving the dust reduction effect.

[0055] At the same time, when blockage occurs or maintenance is required, the foaming structure 12 can be easily replaced, which reduces maintenance costs and time and improves equipment availability and maintenance efficiency.

[0056] Optionally, the foaming structure 12 may be connected to the rotating shaft by threads, or may be connected by locking members such as bolts.

[0057] Furthermore, the foaming structure 12 includes a connecting sleeve 121 and a plurality of foaming elements 122. The connecting sleeve 121 is mounted on the rotating shaft. The plurality of foaming elements 122 are arranged on the connecting sleeve 121 at intervals along the circumference of the connecting sleeve 121. The foaming elements 122 include a foaming net 1221. The foaming net 1221 can generate foam by mixing air, water, and foaming liquid.

[0058] This arrangement facilitates processing of the foaming structure 12. The foaming structure 12 helps to clear blockages on the foaming member 122 during rotation, reduces blockages during foam generation, and ensures continuous and efficient operation of the foaming component 10.

[0059] Furthermore, when a single foaming member 122 is clogged, other unblocked foaming members 122 can be rotated and used, thereby effectively extending the continuous operation time of the entire equipment and reducing maintenance downtime.

[0060] Specifically, in the present application, the fluid outlet 55 is provided corresponding to the fluid inlet 112 , and the fluid inlet 112 is provided away from the rotation axis, so that the fluid inlet 112 can be provided corresponding to the foaming member 122 .

[0061] The dust suppression device includes a plurality of foaming structures 12, which are spaced apart and sleeved on the rotating shaft along the axial direction of the rotating shaft. In this way, the foaming efficiency is improved by the multi-layered foaming structures 12, thereby further improving the dust suppression effect.

[0062] Furthermore, a nozzle 60 is provided at the foam outlet, and the nozzle 60 is communicated with the foam outlet.

[0063] Such a configuration can improve the directionality and coverage of the foam spray. The nozzle 60 can further disperse the foam to form smaller foam particles. These fine foam particles can be better suspended in the air, increase the contact opportunity with dust particles, and improve adsorption efficiency.

[0064] Furthermore, the spraying action of the nozzle 60 can adjust the shape and density of the foam, causing it to remain in the air longer and cover a wider area, thereby achieving more effective dust reduction. Precise foam spraying can reduce foam waste, ensure effective foam utilization, and reduce the overall cost of dust reduction operations.

[0065] Specifically, permanent magnets 70 are provided outside the housing 11 and the hybrid structure 50 , and the permanent magnets 70 are used to magnetize the foam.

[0066] Such an arrangement can further magnetize the foam, further improve the dust adsorption effect of the magnetized foam, and further improve the dust reduction effect of the dust reduction device.

[0067] The dust suppression device further includes a liquid storage structure 80 , which has a liquid storage cavity, and the liquid storage cavity is connected to the liquid delivery pipe 40 .

[0068] Such an arrangement makes it easy to add the foaming liquid into the mixing structure 50 , and at the same time, makes it easy for the staff to add the foaming liquid. Moreover, the staff can observe the liquid level of the foaming liquid and thus add the foaming liquid in time.

[0069] Furthermore, a first solenoid valve 21 is provided on the air delivery pipe 20 , a second solenoid valve 32 is provided on the water delivery pipe 30 , and a third solenoid valve 42 is provided on the liquid delivery pipe 40 .

[0070] With this arrangement, the air supply pipe 20, the water supply pipe 30 and the liquid supply pipe 40 are connected to the mixing chamber 51, forming a collaborative system. The staff can accurately control the proportion and state of each component according to actual needs through the first solenoid valve 21, the second solenoid valve 32 and the third solenoid valve 42 to achieve the best foaming effect and dust reduction effect.

[0071] Specifically, the dust suppression device further includes a control system, which is electrically connected to the first solenoid valve 21 , the second solenoid valve 32 and the third solenoid valve 42 respectively to control the operation of the first solenoid valve 21 , the second solenoid valve 32 and the third solenoid valve 42 .

[0072] Such a setting realizes remote control of the magnetized foam production process, thereby achieving intelligent dust removal, improving the degree of automation of the dust reduction device, reducing manual operation, improving the safety and convenience of operation, and reducing the possibility of workers getting sick.

[0073] The staff can set the structures of the first magnetizing device 31 and the second magnetizing device 41 according to the needs. The first magnetizing device 31 and the second magnetizing device 41 are both existing technologies and will not be described in detail here.

[0074] Therefore, in the present application, water will pass through the first magnetization device 31 during transportation in the water supply pipeline 30, and the first magnetization device 31 will magnetize the water. The foaming liquid will pass through the second magnetization device 41 in the liquid supply pipeline 40, and the second magnetization device 41 can magnetize the foaming liquid. The wind, water and foaming liquid form magnetized foam in the shell 11, and the magnetized foam is discharged through the foam outlet.

[0075] This arrangement facilitates operation, eliminating the need for workers to inject water into the coal seam, reducing their labor intensity. Furthermore, the magnetized foam has a higher dust absorption capacity, which reduces water consumption while ensuring the dust reduction effectiveness of the dust reduction device. During rotation, the foaming structure 12 prevents the accumulation of impurities, thereby preventing impurities from clogging the foaming component 10. Simultaneously, the water in the water pipe 30 flushes the foaming component 10, further reducing the probability of clogging.

[0076] Furthermore, the foaming structure 12 includes a plurality of foaming members 122 , so that when a single foaming member 122 is blocked, other unblocked foaming members 122 can be rotated and used, thereby effectively extending the continuous operation time of the entire equipment and reducing maintenance downtime.
