[0032] Embodiments of the present invention are described in detail below, and 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 be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 7 As shown, an embodiment of the present invention provides a coal mine dust removal system 100, which includes a negative pressure generating device 10, a dust collecting device 20, a suction pipe 30 and a telescopic tube 40 connected in sequence, the suction pipe 30 is provided with a plurality of interfaces 31, the telescopic tube 40 is connected to the interface 31, the telescopic tube 40 and the interface 31 are arranged in a one-to-one correspondence, a handle 41 is provided on the telescopic tube 40, an adjustable support rod 43 is provided between the handle 41 and the telescopic tube 40, the telescopic tube 40 has a dust suction port 42, and the adjustable support rod 43 is used to adjust the orientation angle of the dust suction port 42, thereby improving the dust control efficiency in the coal mine environment and ensuring the health and safety of the operators.

[0034] In this embodiment, the suction pipe 30 can be laid in the underground and surface working areas of the coal mine, and multiple interfaces 31 are set in the laying direction of the suction pipe 30. The telescopic pipe 40 is connected to the interface 31. The telescopic pipe 40 can be dragged to the area where dust is required as needed, which is more convenient to use and has higher suction efficiency. In addition, the staff can adjust the length of the adjustable support rod 43 by holding the handle 41 to change the direction of the dust suction port 42 to ensure that the dust suction port 42 is always aimed at the dust source, thereby significantly improving the dust suction efficiency.

[0035] In summary, the coal mine dust removal system 100 provided in the embodiment of the present invention provides great convenience and flexibility for dust suction by laying a suction pipe 30 in the coal mine working area and presetting multiple interfaces 31 to correspond to the connection of the telescopic tube 40, which can effectively reduce the dust concentration in the coal mine working area and ensure the health and safety of the workers.

[0036] like Figure 2 As shown, in some embodiments, the adjustable support rod 43 includes a first link 431, a second link 432 and a positioning pin 433, one of the first link 431 and the second link 432 is connected to the handle 41, and the other of the first link 431 and the second link 432 is connected to the telescopic tube 40, and a guide cavity 4311 is provided on the first link 431, and at least a portion of the second link 432 is slidably disposed in the guide cavity 4311, a plurality of positioning holes 4312 are provided on the first link 431, and a mounting hole 4321 is provided on the second link 432, and the positioning pin 433 is detachably inserted into the mounting hole 4321 and the positioning hole 4312, so that the orientation angle of the dust suction port 42 can be adjusted as needed.

[0037] Specifically, a guide cavity 4311 is provided in the first connecting rod 431, and the guide cavity 4311 is extended along the length direction of the first connecting rod 431, and can provide a precise sliding track for the second connecting rod 432, so that the staff can easily change the position of the second connecting rod 432 relative to the first connecting rod 431 through push-pull operations, thereby driving the telescopic tube 40 and the dust suction port 42 to adjust the angle.

[0038] In addition, a plurality of positioning holes 4312 are arranged at intervals on the first connecting rod 431, and a mounting hole 4321 corresponding to the positioning hole 4312 is provided on the second connecting rod 432, so that the staff can select appropriate positioning holes 4312 and mounting holes 4321 as needed, and insert the positioning pins 433 into the positioning holes 4312 and the mounting holes 4321, thereby ensuring stability after adjustment and easily achieving angle fixation.

[0039] Furthermore, the adjustable support rod 43 also includes an elastic member 434, which is disposed in the guide cavity 4311, and two ends of the elastic member 434 are correspondingly connected to the first connecting rod 431 and the second connecting rod 432, thereby improving the stability of the structure.

[0040] Specifically, the elastic member 434 plays a role of buffering and supporting in the guide cavity 4311. When the staff adjusts the direction angle of the suction port 42, the second connecting rod 432 slides in the guide cavity 4311, which may cause impact or vibration due to uneven operating force or slight friction in the guide cavity 4311. The elastic member 434 can effectively absorb these impacts and vibrations, reducing noise and wear.

[0041] Secondly, the elastic member 434 can also provide the staff with a smoother adjustment feel. During the adjustment process, the elastic member 434 will generate corresponding elastic force feedback according to the moving direction and strength of the second connecting rod 432, so that the staff can feel a natural damping feeling.

[0042] In addition, the elastic member 434 also has a reset function. When the staff pulls out the positioning pin 433, the elastic member 434 will push and pull the second connecting rod 432 to a relatively stable initial position, which helps to maintain the stability of the adjustable support rod 43 during long-term use. In this embodiment, the elastic member 434 can be set as a spring.

[0043] Furthermore, the ends of the first connecting rod 431 and the second connecting rod 432 are provided with threaded sections 435, and the first connecting rod 431 and the second connecting rod 432 can be connected by threads to correspond to the connection handle 41 and the telescopic tube 40. Specifically, the telescopic tube 40 is provided with a mounting ear, and the mounting ear is provided with a through hole, and the end of the first connecting rod 431 can be inserted into the through hole, and the first connecting rod 431 and the telescopic tube 40 are fixed by a nut.

[0044] In addition, the handle 41 is provided with an installation cavity, and the telescopic tube 40 is inserted into the installation cavity. The handle 41 is also provided with a through hole, which is located on the left and right sides of the installation cavity. The second connecting rod 432 can be inserted into the through hole, and the second connecting rod 432 and the handle 41 are fixed by a nut.

[0045] In some embodiments, the first connecting rod 431 and the second connecting rod 432 may be connected to the handle 41 and the telescopic tube 40 in a hinged manner.

[0046] like Figure 3 and Figure 4 As shown, in some embodiments, the telescopic tube 40 is configured as a bellows, which has elasticity and bendability and can adapt to various complex operating environments. The staff can freely adjust the length and shape of the telescopic tube 40 as needed to better align the suction port 42 with the target area, thereby improving the cleaning efficiency.

[0047] The inner diameter of the telescopic tube 40 is set to 30cm to 35cm. This size range not only ensures sufficient suction transmission efficiency, but also takes into account the convenience and practicality of operation. An inner diameter that is too small may limit the amount of airflow passing through and affect the dust collection effect; while an inner diameter that is too large may increase the overall volume and weight of the device, which is not conducive to carrying and operation. Therefore, the inner diameter size of 30cm to 35cm becomes a balance point, which not only meets the requirements of dust collection performance, but also facilitates users to operate and adjust in actual use. In this embodiment, the inner diameter of the telescopic tube 40 can be set to 32cm, and the outer diameter can be set to 39cm.

[0048] Furthermore, the dust suction port 42 of the telescopic tube 40 is configured to be trumpet-shaped, thereby increasing the dust suction area, so that the telescopic tube 40 can capture dust particles in the air more widely.

[0049] Furthermore, the coal mine dust removal system 100 further includes an air intake grille 421, which is disposed at the dust suction port 42 of the telescopic tube 40, so as to preliminarily sort and filter the airflow entering the dust suction port 42. The air intake grille 421 is generally composed of a series of parallel metal bars or a mesh structure, which can effectively prevent large debris, gravel and other non-dust materials from entering the dust suction pipe, thereby protecting the subsequent filter element 22 and other key components from damage.

[0050] like Figure 1 As shown, in some embodiments, the coal mine dust removal system 100 also includes a plurality of control switches 50, and the control switches 50 and the interfaces 31 are set one by one, and the control switches 50 are used to control the opening and closing of the interfaces 31. Specifically, when a large amount of dust is generated in a certain area in the coal mine, the operator can quickly find the control switch 50 corresponding to the interface 31 connected to the area to perform dust removal. At the same time, if it is necessary to close a task that has been completed or is not needed temporarily, it can also be achieved by closing the corresponding control switch 50, thereby improving the dust removal efficiency.

[0051] In some embodiments, the negative pressure generating device 10 also includes a motor, and the power of the motor is set to 1200w to 3000w. First, the power of the motor directly determines the suction force generated by the negative pressure generating device 10. In industrial places such as coal mines, the dust concentration is high and the particles are large, and a stronger suction force is required to effectively capture and remove them. Therefore, setting the motor power within the range of 1200w to 3000w can ensure that the negative pressure generating device 10 can generate sufficient suction during operation to meet the dust removal requirements.

[0052] Secondly, the setting of this power range also takes into account the balance between energy efficiency and equipment life. Although too high a power can improve suction, it will also increase energy consumption and equipment wear, and reduce service life. The power range of 1200w to 3000w is a relatively reasonable choice, which can not only ensure the dust removal effect, but also control energy consumption and equipment wear within a reasonable range.

[0053] Furthermore, the motor can be configured as an explosion-proof motor.

[0054] like Figure 5 As shown, in some embodiments, the coal mine dust removal system 100 further includes an air guide assembly 32, which has a plurality of mutually parallel air guide plates 321, and the air guide plates 321 are rotatably arranged in the interface 31, so that the air flow path can be quickly responded and adjusted according to different working conditions and dust removal requirements to ensure that the dust is effectively guided into the suction pipe 30. At the same time, the air guide plates 321 can also accelerate the air flow speed to a certain extent, forming local vortices or turbulence, and enhancing the capture and removal effect of dust particles.

[0055] Furthermore, the control switch 50 can control the air guide plate 321 to rotate in the interface 31 to adjust the dust suction capacity at the interface 31. Specifically, when a large amount of dust appears in the working area of ​​the coal mine, the staff can quickly adjust the angle of the air guide plate 321 through the control switch 50 to make the air flow more concentratedly flow to the dust-intensive area, thereby enhancing the dust suction capacity and improving the dust removal efficiency. At the same time, in areas with low dust concentration or requiring fine dust removal, the air flow speed can also be slowed down by adjusting the angle of the air guide plate 321 to avoid excessive disturbance to the surrounding environment and secondary dust lifting.

[0056] like Figure 6 and Figure 7As shown, in some embodiments, the dust collecting device 20 includes a housing 21, a filter element 22 and a cleaning assembly 23. The housing 21 has an inlet 211 and an outlet 212. The inlet 211 is connected to the suction pipe 30, and the outlet 212 is connected to the negative pressure generating device 10. The filter element 22 is disposed in the housing 21. The negative pressure generating device 10 can suck the air containing dust into the housing 21 through the suction pipe 30 and the telescopic tube 40, and then pass the air through the filter element 22, and then discharge the cleaned air through the outlet 212 to form a continuous airflow cycle.

[0057] Furthermore, the cleaning assembly 23 includes a wind wheel 231 and a scraper 233. The wind wheel 231 is rotatably arranged at the inlet 211. The scraper 233 is connected to the rotating shaft 2311 of the wind wheel 231, and the scraper 233 is arranged in close contact with the filter element 22, so that the filter element 22 can be automatically cleaned and the possibility of clogging of the filter element 22 can be reduced. Specifically, when the air containing dust enters the inlet 211, the wind wheel 231 can be driven to rotate, and the wind wheel 231 can drive the scraper 233 to slide back and forth on the surface of the filter element 22 to scrape off the dust attached to the filter element 22, ensuring that the filter element 22 always maintains good filtering performance, which not only reduces the system downtime caused by the clogging of the filter element 22, but also reduces the labor intensity and cost of manually cleaning the filter element 22.

[0058] Furthermore, the filter element 22 includes a first filter layer 221 and a second filter layer 222, the first filter layer 221 is arranged in two groups, the second filter layer 222 is arranged between the two groups of the first filter layer 221, and the second filter layer 222 is arranged to be formed by continuous W-shaped coating. Specifically, the filter element 22 is composed of the first filter layer 221 and the second filter layer 222, forming a unique three-layer filtering structure. The first filter layer 221 is cleverly arranged in two groups, which are respectively located on both sides of the filter element 22, as a preliminary filtering layer. This layer usually uses a coarse-pore filter material, which can effectively intercept large particles of dust and impurities, reduce the burden on the subsequent filter layer, and at the same time maintain a high air permeability to ensure smooth airflow.

[0059] The second filter layer 222 located between the two groups of first filter layers 221 is the core of the entire filter element 22. It is formed by continuous W-shaped coating. This unique design not only increases the surface area of ​​the filter element 22 and provides more dust capture sites, but also prolongs the residence time of dust particles in the filter element 22 through the W-shaped tortuous path, thereby enhancing the filtering effect. In addition, the W-shaped coating also has good self-cleaning properties, which can reduce the adhesion of dust on the surface of the filter element 22 to a certain extent and reduce the risk of clogging.

[0060] Of course, in some embodiments, the first filter layer 221 can also be only arranged on the outside of the second filter layer 222 to form a double-layer filter structure, which can be suitable for those occasions with strict space requirements or requiring rapid replacement of the filter element 22. At the same time, since the mutual interference and resistance between the filter layers are reduced, the permeability of the airflow can be improved.

[0061] In some embodiments, the coal mine dust removal system 100 further includes a dust suppression device 60, which includes a spray rod 61, a water pump and a water tank. The spray rod 61 is arranged at the front end of the telescopic tube 40, and a water vapor nozzle 611 is arranged on the spray rod 61. The spray rod 61 is connected to the water tank through the water pump. Specifically, the dust suppression device 60 sprays fine water mist to the dust-intensive area through the spray rod 61 and the water vapor nozzle 611, so that the dust particles are quickly moistened and gathered into larger particle clusters. Subsequently, the dust suction system uses the negative pressure principle to suck the moistened dust particles into the dust suction pipe, and filters and collects them through components such as the filter element 22. This "first drop and then suck" working mode not only improves the dust removal efficiency, but also effectively reduces the harm of dust to the environment and human body.
