[0002] As mines deepen, large quantities of fine coal and rock dust are generated during underground operations. This includes the mining face, where roadheaders and shearers generate significant dust; the ore conveyance and transfer points in haulage tunnels, where dust is easily generated; and the post-blasting process, where blasting smoke and dust are rapidly removed. This dust poses a serious threat to both human health and production safety. It not only affects underground workers' vision and reduces work efficiency, but, more seriously, long-term inhalation of this dust can lead to serious occupational diseases such as pneumoconiosis, posing a significant threat to workers' health.

[0003] Among the existing technologies, although underground dust removal equipment and technology can reduce dust concentration to a certain extent, there are still many shortcomings. For example, most of the existing dust removal equipment uses filter screens or mesh bags to remove dust. However, when the dust humidity is high (such as after rain or wet material operations), the filter screen is prone to sticking or clogging, resulting in increased ventilation resistance and reduced dust removal efficiency. In addition, the filter screen or mesh bag needs to be cleaned regularly, relying on manual operation, which not only has a low level of automation, but also increases maintenance difficulty and labor costs.

It should be understood that the numbers used in this manner are interchangeable where appropriate so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure as detailed in the appended claims.

[0022] Figure 1 A dust removal method for underground operations is shown according to an exemplary embodiment. The dust removal method is applied to a business processing device of a dust removal device, such as Figures 2-3 As shown, the dust removal equipment also includes a dust removal housing 1, a filter mechanism 2, an isolation plate 3 and a suction fan 4, the dust removal housing 1 is provided with a dust removal activity area and a cleaning activity area, and an air inlet 11 is further provided on the dust removal housing 1 in the dust removal activity area, the filter mechanism 2 is provided with two filter screens 21 and a transport device 22, each filter screen 21 is installed on the transport device 22, the transport device 22 is installed in the dust removal housing 1, and in the case of dust removal operation, a filter screen 21 is set on the dust removal Active area, another filter screen plate 21 is arranged in the cleaning active area; the isolation plate 3 includes a groove frame plate 31 with a strip-shaped notch for the filter screen plate 21 to pass through, and the groove frame plate 31 is movably connected to the dust removal shell 1 between the cleaning active area and the dust removal active area; the suction fan 4 is arranged on the dust removal shell 1 in the dust removal active area in such a way that the suction port of the suction fan 4 faces the air inlet 11, and the filter screen plate 21 is isolated between the air inlet 11 and the suction fan 4.

[0023] In this embodiment, the dust removal shell 1 is used to be detachably installed on a tunnel boring machine used for dust removal on a tunneling face. The end of the dust removal shell 1 used for installation is called the bottom, and the end opposite to the bottom is called the top.

[0024] The air inlet 11 and the suction fan 4 are installed relative to each other, and can be installed directly relative to each other or not directly relative to each other. The filter plate 21 is installed at intervals between the air inlet 11 and the filter plate 21. The suction fan 4 is electrically connected to the business processing equipment. The business processing equipment controls the suction fan 4 to start, and the suction fan 4 begins to suck dust from the outside. The dust is sucked into the dust removal shell 1 through the air inlet 11 and the filter plate 21. If a cache area for alleviating dust is provided in the dust removal shell 1 opposite the air inlet 11, the coal blocks with large particles will be sucked into the dust removal activity area along with the dust, and the large particles will be filtered out by the filter plate 21. Small dust enters the buffer zone under the action of the suction fan 4.

[0025] In this embodiment, when the filter plate 21 needs to be cleaned, the transport device 22 can just drive the filter plate 21 through the strip-shaped gap. As an embodiment, a flexible brush is provided in the strip-shaped gap to intercept dust and particles attached to the filter plate 21 onto the isolation plate 3.

[0026] In this embodiment, the business processing device can be installed on the external top end, bottom end or side wall of the dust removal housing 1.

[0027] In some embodiments, the dust removal housing 1 is sequentially arranged from top to bottom with a dust removal area, a cleaning area, and a dirt filtration area. The isolation plate 3 also includes a push-pull groove box 3232 for collecting dirt. The push-pull groove box 32 is disposed at the bottom of the dust removal housing 1 within the dirt filtration area. In this embodiment, the push-pull groove box 32 is configured to catch dust and sludge in the cleaning area after cleaning, allowing it to be pulled out for immediate cleaning. In actual use, dust may become moist during water mist cleaning. This moisture may be drawn into the filter plate 21 along with the dust. Some large particles of ore or mud formed by moisture and dust may adhere to the filter plate 21.

[0028] The dust removal method may include the following steps:

[0029] Step 101: When dust removal is required, start the suction fan 4.

[0030] In this embodiment, the business processing device can be electrically connected to an external electronic device, and can also receive a start button pressed by the user to start dust removal, so as to start dust removal.

[0031] Step 102 , when it is determined that the filter screen plate 21 needs to be cleaned, the suction fan 4 is stopped to determine whether the groove frame plate 31 has been cleaned. If so, step 103 is executed.

[0032] In this step, the camera 9 can be used to identify whether the filter panel 21 needs to be cleaned. As an embodiment, the dust removal equipment also includes a camera 9, which is arranged in the dust removal shell 1 and takes real-time photos of the filter panel 21 set in the dust removal activity area, and sends the taken photos to the business processing equipment. If the business processing equipment learns that cleaning is required after analyzing the photos, it outputs a cleaning signal indicating that the filter panel 21 needs to be cleaned.

[0033] Step 103 , controlling the transport device 22 to start, so that the filter screen plate 21 in the dust removal activity area is swapped with the filter screen plate 21 in the cleaning activity area, so as to clean the filter screen plate 21 .

[0034] The transport device 22 can start the filter screen plate 21 that needs to be cleaned, so that the filter screen plate 21 in the dust removal activity area passes through the strip-shaped gap and is driven by the transport device 22 to exchange positions with the filter screen plate 21 in the cleaning activity area to clean the filter screen plate 21. After determining that the filter screen plate 21 has successfully exchanged positions, continue to start the suction fan 4.

[0035] Step 104: After determining that the filter screen plates 21 have been successfully interchanged, continue to start the suction fan 4.

[0036] It can be seen that in the technical solution of the present application, the dust removal method is applied to the business processing equipment of the dust removal equipment, and the dust removal equipment also includes a dust removal shell 1, a filter mechanism 2, an isolation plate 3 and a suction fan 4. The dust removal shell 1 is provided with a dust removal activity area and a cleaning activity area, and an air inlet 11 is also provided on the dust removal shell 1 in the dust removal activity area. The filter mechanism 2 is provided with two filter screens 21 and a transport device 22. Each filter screen 21 is installed on the transport device 22, and the transport device 22 is installed in the dust removal shell 1. When the dust removal operation is performed, one filter screen 21 is arranged in the dust removal activity area, and the other filter screen 21 is arranged in the cleaning activity area; the isolation plate 3 includes a groove frame plate provided with a strip-shaped notch for the filter screen 21 to pass through 31, the groove frame plate 31 is movably connected to the dust removal shell 1 between the cleaning activity area and the dust removal activity area; the suction fan is arranged on the dust removal shell 1 in the dust removal activity area in an installation manner in which the suction port of the suction fan faces the air inlet 11, and the filter plate 21 is isolated between the air inlet 11 and the suction fan 4; the dust removal method starts the suction fan when dust removal is needed; when it is determined that the filter plate 21 needs to be cleaned, the suction fan is stopped to determine whether the groove frame plate 31 has been cleaned. If so, the transportation device 22 is controlled to start, so that the filter plate 21 in the dust removal activity area and the filter plate 21 in the cleaning activity area are exchanged in position to clean the filter plate 21. After determining that the filter plate 21 has been successfully exchanged in position, the suction fan is continued to be started. As can be seen, the business processing equipment used in the dust removal method provided in the embodiment of the present application can control the transport device 22 to transport the dust-attached dirt to the cleaning area for automatic cleaning, eliminating the need for manual operation. This allows for both timely cleaning of clogged filter panels 21 and timely cleaning. Furthermore, while cleaning the filter panels 21, the clean filter panels 21 can be used for continued dust removal. This not only improves dust removal efficiency but also enhances automation, reducing maintenance difficulty and labor costs.

[0037] When the business processing device determines that the filter panel 21 needs to be cleaned, it controls the transport device 22 to move the filter panel 21 that needs to be cleaned from the dust removal activity area to the cleaning activity area, and simultaneously moves the cleaned filter panel 21 from the cleaning activity area to the dust removal activity area. In actual application, only one of the two filter panels 21 can be in the cleaning activity area or the dust removal activity area. In some embodiments, the transport device 22 includes a mobile transport mechanism 221, which is installed in the dust removal housing 1. Each filter panel 21 is installed at a corresponding set position of the mobile transport mechanism 221 and is electrically connected to the business processing device.

[0038] The method for realizing the control of starting the transport device 22 in step 103 so that the filter screen panel 21 in the dust removal activity area and the filter screen panel 21 in the cleaning activity area are interchanged may include the following steps:

[0039] When it is determined that the filter screen plate 21 needs to be cleaned, the mobile transfer mechanism 221 is controlled to start, so as to drive each of the filter screen plates 21 from the current end to another designated end.

[0040] In this embodiment, each filter screen plate 21 is installed at opposite ends of the mobile transfer mechanism 221, such as one filter screen plate 21 is located at the upper end of the mobile transfer mechanism 221, and the other filter screen plate 21 is located at the lower end of the mobile transfer mechanism 221. The purpose is to ensure that while washing dust, the dirty filter screen plate 21 can also be cleaned synchronously, thereby improving the efficiency of dust washing and increasing the life of the dust removal equipment.

[0041] In some embodiments, the mobile transport mechanism 221 includes: a rotating motor 2211, three bearings, four rotating shafts 2212, eight gears 2213 and four set segment tooth chains 2214;

[0042] The rotating motor 2211 is installed at a specified position on the inner wall of the dust removal shell 1. A gear is provided on the output end of the rotating motor 2211. The gear is connected to another gear through a rotating shaft 2212. Each bearing is installed at a specified position on the inner wall of the dust removal shell 1 and is connected to one end of the corresponding rotating shaft 2212. The other end of each rotating shaft 2212 is correspondingly provided with a gear 2213. Each section of the tooth chain 2214 passes around the corresponding gear 2213 and is connected to the edge of the corresponding filter plate 21.

[0043] The control of starting the mobile transfer mechanism 221 includes:

[0044] The rotating motor 2211 is controlled to rotate so that the first filter screen plate and the second filter screen plate can be interchanged between the dust removal activity area and the cleaning activity area under the drive of the tooth chain 2214.

[0045] When the rotating motor 2211 rotates, the gear 2213 connected to the rotating motor 2211 rotates with the tooth chain 2214. The tooth chain 2214 rotates synchronously through the gears 2213 connected to each of them, and each rotating shaft 2212 is connected to a bearing to support the gear 2213.

[0046] In this embodiment, the first ends of the first tooth chain are respectively connected to the first end of the first side of the first filter plate, the second end of the first tooth chain crosses the gear 2213 and is connected to the first end of the first side of the second filter plate, the first end of the second tooth chain is connected to the first end of the second side of the first filter plate opposite to the first side, and the second end of the second tooth chain crosses the gear 2213 and is connected to the first end of the second side of the second filter plate opposite to the first side; the first ends of the third tooth chain are respectively connected to the second end of the first side of the first filter plate, the second end of the third tooth chain crosses the gear 2213 and is connected to the second end of the first side of the second filter plate, the first end of the fourth tooth chain is connected to the second end of the first filter plate and the second side, and the second end of the fourth tooth chain crosses the gear 2213 and is connected to the second end of the second side of the second filter plate.

[0047] The first filter plate and the second filter plate are named for ease of distinction only and are not intended to limit any particular filter plate. The first toothed chain is named for ease of distinction from the toothed chain 2214 described below and is not intended to limit any particular toothed chain 2214. Accordingly, the second toothed chain is named for ease of distinction from the toothed chains described above or below and is not intended to limit any particular toothed chain. The third toothed chain is named for ease of distinction from the toothed chains described below and is not intended to limit any particular toothed chain. Accordingly, the fourth toothed chain is named for ease of distinction from the toothed chains described above or below and is not intended to limit any particular toothed chain.

[0048] The first and second toothed chains can both move in conjunction with their respective gears 2213. The first side of the first toothed chain and the second side of the first chain form a pair of opposing sides. Correspondingly, the first side of the second toothed chain and the second side of the second chain form a pair of opposing sides, the first side of the third toothed chain and the second side of the third chain form a pair of opposing sides, and the first side of the fourth toothed chain and the second side of the fourth chain form a pair of opposing sides.

[0049] The first end of the first side of the first toothed chain and the second end of the first side of the first chain form a pair of opposite ends. Accordingly, the first end of the second side of the second toothed chain and the second end of the second side of the second chain form a pair of opposite ends. The first end of the second side of the third toothed chain and the second end of the second side of the third chain form a pair of opposite ends. The first end of the second side of the third toothed chain and the second end of the second side of the third chain form a pair of opposite ends, and so on.

[0050] In this embodiment, when the rotating motor 2211 rotates, it drives the gear 2213 via the toothed chain 2214 to achieve synchronous transportation. Thus, the first and second filter panels can be driven by the rotating motor 2211 to achieve synchronous movement, placing one filter panel 21 in the cleaning zone and the other in the dust removal zone. In actual use, when the business processing device determines that a filter panel 21 needs cleaning, it controls the rotating motor 2211, causing the gear 2213 to rotate the toothed chain 2214, so that the filter panel 21 in need of cleaning moves to the cleaning zone. Simultaneously, the cleaned filter panel 21 moves to the dust removal zone.

[0051] In other embodiments, the dust removal device further includes a limit sensor mounted at a set position on the toothed chain 2214. The dust removal method further includes controlling the rotating motor 2211 to stop rotating upon receipt of a position feedback signal from the limit sensor indicating that the position has been reached. When the toothed chain 2214 rotates and the limit sensor, driven by the toothed chain 2214, reaches a certain position, it receives a position feedback signal indicating that the set position has been reached. This position feedback signal is then transmitted to the service processing device, causing the rotating motor 2211 to stop rotating. The cessation of the rotating motor 2211 indicates that the filter panel 21 to be cleaned has reached the active cleaning zone.

[0052] In other embodiments, four strip-shaped notches are provided in the groove frame plate 31 at a position close to the tooth chain 2214, and each of the strip-shaped notches passes through the corresponding tooth chain 2214 and is engaged with the gear 2213. The dust removal equipment also includes a flipping mechanism 5, which is arranged in the dust removal shell 1 and connected to the groove frame plate 31; the dust removal method also includes the following steps: when it is determined that the dust in the groove frame plate 31 needs to be cleaned or the filter plate 21 needs to be cleaned, the flipping mechanism 5 is controlled to start to drive the groove frame plate 31 to flip.

[0053] In this embodiment, as the flip mechanism 5 drives the groove frame plate 31 to flip, the strip-shaped notch is tilted relative to the tooth chain 2214. However, the provision of the strip-shaped notch prevents interference of the gear 2213 chain with the groove frame plate 31. The flip mechanism 5 can drive the groove frame plate 31 to flip at a set angle, so that the dust stored in the groove frame plate 31 is poured into the designated area as the groove frame plate 31 flips, thereby achieving a cleaning effect. This can not only collect large particles of coal, but also prevent the dust cleaning activity area from entering and further contaminating the filter screen plate 21 being cleaned. The spacing area between the two filter screen plates 21 is precisely where the groove frame plate 31 is placed. When the groove frame plate 31 is in a horizontal state, the two filter screen plates 21 are precisely isolated from the cleaning activity area and the dust removal activity area. As an embodiment, the groove frame plate 31 is further provided with multiple dustproof covers, each of which is installed within the strip-shaped notch. In this embodiment, the dustproof covers can effectively prevent dust from entering the cleaning area through the strip-shaped notch, while also collecting dust for disposal into a designated area within the cleaning area when the flip mechanism 5 is flipped. The dustproof covers can be soft rubber covers that do not interfere with the rotation of the toothed chain 2214 when the flip mechanism 5 is not flipping. During the flipping process, the toothed chain 2214 is in a disabled state. The dustproof covers can also be brushes that are attached to the strip-shaped notch.

[0054] In other embodiments, Figures 2-3 As shown, the flip mechanism 5 includes a flip motor 51, a motor mounting frame and a rotating wheel mechanism 52; the flip motor 51 is mounted on the motor mounting frame, and the motor mounting frame is mounted at a specified position on the inner wall of the dust removal housing 1, the output end of the flip motor 51 is mounted with the input end of the rotating wheel mechanism 52, and the groove frame plate 31 is mounted on the rotating wheel surface of the rotating wheel mechanism 52; the implementation method of controlling the startup of the flip mechanism 5 may include the following steps: controlling the rotation of the flip motor 51 to control the rotating wheel mechanism 52 to drive the groove frame plate 31 to flip while rotating. In this embodiment, the groove frame plate 31 is mounted on the rotating wheel surface of the rotating wheel mechanism 52. When the flip motor 51 rotates, the rotating wheel mechanism 52 drives the groove frame plate 31 to flip, so that the dust stored in the groove frame plate 31 enters the specified area as it flips. In other embodiments, the dust removal device further includes a dirt guide channel plate 6, which is installed in the dust removal housing 1 so that the groove frame plate 31 is aligned with the dirt guide channel plate 6 when flipped over, so that dirt is guided by the dirt guide channel plate 6 and injected into the push-pull groove box body 32 at the bottom of the cleaning activity area. The dirt guide channel plate 6 of this embodiment can precisely guide the dirt in the groove frame plate 31 into the push-pull groove box body 32.

[0055] The dust removal device also includes a gravity sensor installed at a location between the groove frame plate 31 and the rotating wheel mechanism 52. Prior to controlling the activation of the flip mechanism 5, the device also includes the following steps: receiving gravity feedback information from the gravity sensor in real time, and controlling the flip mechanism 5 to rotate if it is determined that the gravity feedback information exceeds a set threshold. In this embodiment, the gravity sensor can measure the weight of the groove frame plate 31. When the measured weight reaches a set weight, it indicates that the dust in the groove frame plate 31 has reached a predetermined capacity and that it is time to clean it. Based on this, the business processing device controls the flip motor 51 to flip the groove frame plate 31 when the received weight exceeds the threshold.

[0056] In other embodiments, the dust removal equipment is provided with a spraying device 7 for spraying water, and the spraying device 7 is installed on the dust removal housing 1 through the dust removal housing 1 facing the filter screen 21; the dust removal equipment further includes: a cleaning brush mechanism 8 for cleaning, the cleaning brush mechanism 8 is arranged in the dust removal housing 1 within the cleaning activity area, and the spraying device 7 and the cleaning brush mechanism 8 are both electrically connected to the business processing equipment. The above-mentioned implementation method of cleaning the filter screen 21 may include the following steps:

[0057] In step A1, it is determined whether the filter panel 21 within the cleaning activity area is the filter panel close to the spraying device 7 or the filter panel 21 away from the spraying device 7. If the filter panel 21 within the cleaning activity area is determined to be the filter panel 21 close to the spraying device 7, step A2 is executed. If the filter panel 21 within the cleaning activity area is determined to be the filter panel 21 away from the spraying device 7, step A3 is executed.

[0058] In this embodiment, the spraying device 7 passes through the dust removal shell 1 and is installed on the dust removal shell 1. It can obtain water from the outside and spray water under the control of the business processing equipment to clean the filter plate 21 under the action of the cleaning brush mechanism 8.

[0059] Step A2: Control the spraying device 7 to spray water at a first pressure value, and control the cleaning brush mechanism 8 to clean the filter screen 21 simultaneously.

[0060] The first pressure value is simply a name for the following pressure values ​​for ease of distinction and is not intended to limit a specific pressure value. The water source for the spraying device 7 can be external. Under the control of the business processing device, the external water source is pumped into the spraying device 7 and sprayed according to the determined pressure value to clean the attached matter in the filter screen 21.

[0061] Step A3: Control the spraying device 7 to spray water at a second pressure value greater than the first pressure value, and control the cleaning brush mechanism 8 to clean the filter screen 21 simultaneously.

[0062] The second pressure value is only a name given to the previous pressure value for the convenience of distinction and is not used to limit a certain pressure value.
