[0002] A mine shaft is a general term encompassing the shafts, chambers, equipment, surface buildings, and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, and adits in underground mine development are also referred to as mine shafts. Determining the size of each mine's mining area, its production capacity, and its service life is one of the key issues that must be addressed in the mine's self-design.

[0003] In related technologies, ventilation devices in coal mines are mostly straight pipes. When ventilation is carried out through pipes, dust in the air can easily enter the mine, reducing the air quality and causing harm to the human body. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a dust removal and ventilation device with a simple structure that can improve the air quality in mines.

[0006] The dust removal and ventilation device according to an embodiment of the present invention includes: a housing having a dust removal chamber, an inlet, and an outlet, the inlet and the outlet both communicating with the dust removal chamber; the housing being adapted to be installed in a tunnel so that gas in the tunnel flows into the dust removal chamber through the inlet and flows out through the outlet; a filter element detachably disposed in the housing and located between the inlet and the outlet, the filter element being used to filter impurities in the air of the dust removal chamber; a cleaning assembly disposed in the housing and cooperating with the filter element so that the cleaning assembly cleans the filter element; and a traveling assembly disposed below the housing, the traveling assembly having a traveling state and a locked state; in the traveling state, the traveling assembly moves the housing within the tunnel; and in the locked state, the housing remains stationary within the tunnel.

[0007] The dust removal and ventilation device of this invention includes a housing, a filter element, a cleaning component, and a traveling component. The filter element filters the gas in the tunnel, reducing dust in the gas and improving the gas quality, thus reducing harm to workers in the tunnel. The cleaning component cleans the filter element, ensuring efficient cleaning. Finally, the traveling component allows the dust removal and ventilation device to move within the tunnel, enabling it to filter gas in heavily polluted areas and improving dust removal efficiency.

[0008] In some embodiments, the inlet is located on one side of the housing, the outlet is located on the other side of the housing, the inlet is located above the outlet in a projection plane orthogonal to the width direction of the housing, and the filter element is located between the outlet and the inlet.

[0009] In some embodiments, the dust removal and ventilation device further includes an exhaust assembly disposed within the outlet, the exhaust assembly being used to extract gas from the filter chamber.

[0010] In some embodiments, the cleaning assembly includes: a first cleaning member disposed below and in contact with the filter element, the first cleaning member being movable relative to the length direction of the filter element so as to clean the filter element; and a second cleaning member disposed within the housing and above the filter element, the second cleaning member being used to spray cleaning fluid onto the filter element to clean it.

[0011] In some embodiments, the first cleaning component includes: a cleaning frame disposed within the housing and located below the filter element, the cleaning frame being movable along the length of the filter element, and one end of the cleaning frame extending outside the housing; and a cleaning brush disposed at the other end of the cleaning frame and in contact with the filter element, so that the cleaning frame drives the cleaning brush to clean the filter element.

[0012] In some embodiments, the second cleaning component includes a pipe and a plurality of nozzles. The pipe is disposed within the housing and above the filter element. The plurality of nozzles are disposed below the pipe and spaced apart along the extension direction of the pipe. The plurality of nozzles are located above the filter element and communicate with the pipe. The pipe is adapted to carry cleaning fluid so that the cleaning fluid is sprayed onto the filter element through the nozzles.

[0013] In some embodiments, the housing includes a first cavity and a second cavity arranged sequentially in a vertical direction. The first cavity is located above the second cavity. The outlet and the inlet are both formed on the first cavity. The filter element and the cleaning assembly are both disposed in the first cavity. The second cavity is used to store cleaning fluid. The second cleaning assembly communicates with the second cavity so that the cleaning fluid in the second cavity flows into the second cleaning assembly. The second cleaning assembly also includes a heating unit disposed in the second cavity. The heating unit is used to heat the cleaning fluid in the second cavity.

[0014] In some embodiments, the housing is provided with a first flange and a second flange, both of which extend circumferentially along the housing and are spaced apart in the vertical direction.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The dust removal and ventilation device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, the dust removal and ventilation device 100 according to an embodiment of the present invention includes a housing 1, a filter element 2, a cleaning component 3, and a walking component 4.

[0024] The housing 1 has a dust collection chamber 11, an inlet 12, and an outlet 13. Both the inlet 12 and the outlet 13 are connected to the dust collection chamber 11. The housing 1 is suitable for installation in a roadway, so that gas in the roadway flows into the dust collection chamber 11 through the inlet 12 and flows out through the outlet 13. Specifically, as... Figure 1 As shown, the housing 1 is the basic structure of the entire dust removal and ventilation device 100 and can be a rectangular structure. The housing 1 has a dust removal chamber 11, an inlet 12, and an outlet 13. Both the inlet 12 and the outlet 13 are connected to the dust removal chamber 11. The gas in the tunnel can flow into the dust removal chamber 11 through the inlet 12, and after being treated, it flows out from the outlet 13, thereby completing the gas purification cycle.

[0025] The filter element 2 is detachably installed inside the housing 1 and located between the inlet 12 and the outlet 13. The filter element 2 is used to filter impurities in the air within the dust removal chamber 11. Specifically, as shown... Figure 1 and Figure 2 As shown, filter element 2 is installed inside housing 1 and located between inlet 12 and outlet 13. Gas enters dust collection chamber 11 through inlet 12, passes through filter element 2, and reaches outlet 13. The main function of filter element 2 is to filter impurities in the air within dust collection chamber 11, effectively removing dust, particulate matter, and other pollutants from the gas, ensuring that the gas exiting outlet 13 meets cleanliness standards. Furthermore, after a period of use, the filtration performance of filter element 2 may decrease. At this time, it can be easily disassembled for maintenance or replaced with a new filter element 2 to ensure the continuous and efficient operation of the device.

[0026] The cleaning component 3 is located inside the housing 1 and cooperates with the filter element 2 so that the cleaning component 3 can clean the filter element 2. Specifically, as follows: Figure 1 and Figure 2 As shown, the cleaning component 3 is installed inside the housing 1 and cooperates with the filter element 2. During the operation of the dust removal and ventilation device 100, impurities will continuously accumulate in the filter element 2. Over time, these impurities will clog the pores of the filter element 2, affecting its filtration effect. The cleaning component 3 can periodically or as needed clean the filter element 2, removing impurities attached to its surface, restoring its filtration performance, and ensuring the filtration efficiency of the filter element 2.

[0027] The traveling component 4 is located below the housing 1. The traveling component 4 has a traveling state and a locked state. In the traveling state, the traveling component 4 moves the housing 1 within the aisle; in the locked state, the housing 1 remains stationary within the aisle. Specifically, as... Figure 1 and Figure 2 As shown, the traveling component 4 is located below the housing 1 and has two operating states: traveling state and locked state. In the traveling state, the traveling component 4 can move the entire housing 1 within the tunnel. This allows the dust removal and ventilation device 100 to be adjusted in position according to actual conditions, such as switching between different working areas or moving the device to a more heavily polluted area for focused treatment based on changes in the degree of gas pollution within the tunnel. In the locked state, the housing 1 remains stationary within the tunnel, ensuring the stability of the device during filtration and cleaning, and guaranteeing the dust removal efficiency of the dust removal and ventilation device 100.

[0028] The dust removal and ventilation device 100 of this invention includes a housing 1, a filter element 2, a cleaning component 3, and a traveling component 4. The filter element 2 filters the gas in the tunnel, reducing dust in the gas and improving the gas quality, thus reducing harm to workers in the tunnel. In addition, the cleaning component 3 can clean the filter element 2, ensuring cleaning efficiency. Finally, the traveling component 4 allows the dust removal and ventilation device 100 to move within the tunnel, enabling it to filter gas in heavily polluted areas and improving dust removal efficiency.

[0029] In some embodiments, the inlet 12 is located on one side of the housing 1, and the outlet 13 is located on the other side of the housing 1, in a direction orthogonal to the width of the housing 1 (e.g., ...). Figure 1 In the projection plane (shown in the front-to-back direction), inlet 12 is located below outlet 13, and filter element 2 is disposed between outlet 13 and inlet 12. Specifically, as shown... Figure 1 and Figure 2 As shown, outlet 13 is located on the left side of housing 1, and inlet 12 is located on the right side of housing 1. Inlet 12 is positioned above outlet 13. Larger particles in the gas, due to their greater weight, sink to the bottom of housing 1. The gas is then discharged from housing 1 through outlet 13, thus effectively separating some of the larger particles, reducing the burden on subsequent filter element 2, and improving the overall dust removal efficiency. Filter element 2 is positioned between outlet 13 and inlet 12, thereby filtering the gas inside housing 1.

[0030] In some embodiments, the dust removal ventilation device 100 further includes an exhaust assembly 14, which is disposed within the outlet 13 and is used to extract gas from the filter chamber. Specifically, as Figure 2As shown, the exhaust assembly 14 is an exhaust fan and is located inside the outlet 13. When the exhaust assembly 14 is started, the high-speed rotation of the impeller inside the exhaust assembly 14 allows the outside air to enter the interior of the housing 1 from the inlet 12, be filtered by the filter element 2, and then enter the mine from the outlet 13.

[0031] In some embodiments, the cleaning component 3 includes a first cleaning component 31 and a second cleaning component 32.

[0032] The first cleaning element 31 is located below the filter element 2 and is in contact with the filter element 2. The first cleaning element 31 is movable relative to the length of the filter element 2 so that the first cleaning element 31 cleans the filter element 2. Specifically, as shown in the figure... Figure 2 As shown, the first cleaning component 31 is disposed inside the housing 1 and located below the filter element 2. The first cleaning component 31 is in contact with the filter element 2. When the filter element 2 needs to be cleaned, the first cleaning component 31 reciprocates in the left-right direction. During the movement, the direct contact between the first cleaning component 31 and the surface of the filter element 2, through physical actions such as friction and scraping, effectively removes dust, particles, and other impurities adhering to the surface of the filter element 2, thereby ensuring the cleanliness of the surface of the filter element 2 and maintaining its good filtration performance.

[0033] The second cleaning component 32 is located inside the housing 1 and above the filter element 2. The second cleaning component 32 is used to spray cleaning fluid onto the filter element 2 to clean it. Specifically, as shown... Figure 2 As shown, the second cleaning component 32 is installed inside the housing 1 and located above the filter element 2. The second cleaning component 32 sprays cleaning liquid onto the filter element 2 to clean it. The cleaning liquid comes into full contact with the impurities on the surface of the filter element 2. Through dissolution, rinsing and other actions, the impurities on the filter element 2 are removed, further improving the cleanliness and filtration effect of the filter element 2.

[0034] In some embodiments, the first cleaning component 31 includes a cleaning frame 311 and a cleaning brush 312.

[0035] The cleaning frame 311 is located inside the housing 1 and below the filter element 2. The cleaning frame 311 is movable along the length of the filter element 2. One end of the cleaning frame 311 extends outside the housing 1, and the cleaning brush 312 is located at the other end of the cleaning frame 311 and contacts the filter element 2, so that the cleaning frame 311 can drive the cleaning brush 312 to clean the filter element 2. Specifically, as shown... Figure 2As shown, the right end face of the housing 1 is provided with a mounting hole that runs through the housing 1 in the left-right direction. The cleaning frame 311 is a pull rod that extends in the left-right direction. The left part of the cleaning frame 311 passes through the mounting hole and is installed inside the housing 1 and located below the filter element 2. The cleaning brush 312 is provided on the upper end face of the left end of the cleaning frame 311. The cleaning brush 312 is in contact with the filter element 2. Thus, by pulling the cleaning frame 311, the cleaning brush 312 is moved in the left-right direction, so that the cleaning brush 312 cleans the impurities on the filter element 2, avoids clogging of the holes on the filter element 2, extends the service life of the filter element 2, and reduces the maintenance cost and operating risk of the equipment.

[0036] In some embodiments, the second cleaning component 32 includes a pipe 321 and a plurality of nozzles 322. The pipe 321 is disposed inside the housing 1 and above the filter element 2. The plurality of nozzles 322 are disposed below the pipe 321 and spaced apart along the extending direction of the pipe 321. The plurality of nozzles 322 are all located above the filter element 2 and communicate with the pipe 321. The pipe 321 is adapted to carry cleaning fluid so that the cleaning fluid is sprayed onto the filter element 2 through the nozzles 322. Specifically, as shown... Figure 2 As shown, pipe 321 runs through the housing 1 and is located above filter element 2. Multiple nozzles 322 are located below pipe 321 and connected to it. When cleaning of filter element 2 is required, an appropriate amount of cleaning solution is delivered to pipe 321 through an external liquid supply system (such as water pump 323, storage tank, etc.). During the flow of the cleaning solution within pipe 321, it is distributed to each nozzle 322. Subsequently, the cleaning solution is sprayed onto filter element 2 under high pressure inside nozzle 322, thereby rinsing and cleaning dust, particles, and other impurities on filter element 2.

[0037] In some embodiments, the housing 1 includes a first cavity 111 and a second cavity 112 arranged sequentially in a vertical direction. The first cavity 111 is located above the second cavity 112. An outlet 13 and an inlet 12 are both formed on the first cavity 111. A filter element 2 and a cleaning assembly 3 are both disposed in the first cavity 111. The second cavity 112 is used to store cleaning fluid. A second cleaning assembly 32 communicates with the second cavity 112 so that the cleaning fluid in the second cavity 112 flows into the second cleaning assembly 32. The second cleaning assembly 32 also includes a heating unit 324 disposed in the second cavity 112 and used to heat the cleaning fluid in the second cavity 112. Specifically, as shown... Figure 2As shown, the first cavity 111 is an installation cavity, and the second cavity 112 is a storage cavity located above the first cavity 111. The outlet 13 and the inlet 12 are both formed on the first cavity 111. The filter element 2 and the first cleaning element 31 are both disposed in the first cavity 111. The second cavity 112 can store cleaning fluid. The heating unit 324 is an electric heating plate disposed in the second cavity 112. By adding water into the second cavity 112, the water is heated to boiling by turning on the electric heating plate. The boiling water is then pumped to the pipe 321 by the water pump 323, and then the filter element is rinsed by the nozzle 322. The filter element 2 can also be disinfected, ensuring the filtration efficiency of the filter element 2.

[0038] In some embodiments, the housing 1 is provided with a first flange 15 and a second flange 16, both extending circumferentially along the housing 1 and spaced apart vertically. The filter element 2 is a filter screen and is disposed between the first flange 15 and the second flange 16. The first flange 15 is provided with a threaded through hole extending vertically through the first flange 15. A fastener 18 is threaded into the threaded through hole, and the lower end of the fastener 18 abuts against the filter element 2. Specifically, as shown... Figure 2 and Figure 3 As shown, the first flange 15 and the second flange 16 are both annular and fixed on the inner circumferential surface of the housing 1. The first flange 15 and the second flange 16 are spaced apart in the vertical direction. The filter element 2 is a filter screen and is located between the first flange 15 and the second flange 16. The first flange 15 is provided with a plurality of threaded through holes that penetrate the first flange 15 in the vertical direction. The plurality of threaded through holes are spaced apart in the circumferential direction of the housing 1. There are a plurality of fasteners 18, which are bolts. Each threaded through hole is provided with a bolt that passes through the threaded through hole and abuts against the filter element 2. Thus, the filter element 2 is detachably installed in the housing 1 by means of the first flange 15, the second flange 16 and the fasteners 18.

[0039] In some embodiments, the dust removal and ventilation device 100 further includes a plurality of support members 5, which extend vertically and are located at the bottom of the housing 1, and are spaced apart circumferentially along the housing 1. Specifically, as shown in... Figure 1 and Figure 2 As shown, the support member 5 is a vertical rod extending in the vertical direction. There are 4 support members 5, all of which are located at the bottom of the box 1. The bottom end of each support member 5 is glued with an anti-slip pad to prevent the box 1 from sliding.

[0040] In some embodiments, the walking component 4 includes a mounting bracket 41, a mounting base 42, and a drive element 43.

[0041] Mounting bracket 41 is located at the bottom of housing 1 and connected to housing 1. Mounting base 42 is located on mounting bracket 41 and is movable vertically relative to mounting base 42. Rollers 44 are provided below mounting base 42. Specifically, as shown... Figure 1 and Figure 2 As shown, the mounting frame 41 is located at the bottom of the housing 1 and connected to the housing 1. Multiple support members 5 are located below the mounting frame 41. The mounting base 42 is located above the mounting frame 41 and can move up and down on the mounting frame 41 between a first position and a second position. Multiple rollers 44 are provided below the mounting base 42. In the first position, the mounting base 42 moves downward so that the multiple rollers 44 abut against the bottom surface of the tunnel, and the support rod separates from the bottom surface of the tunnel, thereby allowing the housing 1 to move in the tunnel. In the second position, the mounting base 42 moves upward, the rollers 44 separate from the bottom surface of the tunnel, and the support members 5 support the bottom surface of the tunnel, thereby fixing the housing 1 in the bottom surface of the tunnel.

[0042] In some embodiments, the driving member 43 passes through the mounting bracket 41 and is connected to the mounting base 42, and the driving member 43 is used to drive the mounting base 42 to move in the vertical direction. Specifically, as Figure 1 and Figure 2 As shown, the mounting base 42 is provided with a threaded through hole that extends through the mounting base 42 in the vertical direction. The driving member 43 is a threaded rod and is inserted into the threaded through hole of the mounting base 42. The lower end of the driving member 43 is hinged to the mounting bracket 41 (for example, the mounting bracket 41 is provided with a mounting groove, and the lower end of the driving member 43 is rotatably inserted into the mounting groove). Thus, by rotating the driving member 43, the mounting base 42 can be moved between the first position and the second position in the vertical direction.

[0043] Example 1, referring to Figures 1-3 The dust removal and ventilation device 100 includes a housing 1, on which a filter element 2, a cleaning component 3, and a support element 5 are provided. A side door 17 is installed on the upper part of the front side of the housing 1, and a sealing ring is provided on the edge of the side door 17.

[0044] An inlet 12 is located in the middle of the left side of the housing 1, and an outlet 13 is installed on the top right side of the housing 1. An exhaust assembly 14 is installed in the outlet 13. The inlet 12 is connected to the ventilation duct 321 in the mine. By turning on the exhaust assembly 14, outside air can enter the interior of the housing 1 through the inlet 12 and then enter the mine through the outlet 13. The filter element 2 includes a first flange 15 and a second flange 16 installed on the upper part of the inner wall. An over-filter element 2 is installed between the first flange 15 and the second flange 16. The filter element 2 is located between the outlet 13 and the inlet 12. The air can be filtered through the over-filter element 2.

[0045] The cleaning component 3 includes a cleaning frame 311 inserted into one side of the housing 1. The cleaning frame 311 is connected to a cleaning brush 312 at one end inside the housing 1. The cleaning brush 312 is located below the filter element 2 and is provided with bristles. By pushing and pulling the cleaning frame 311, the cleaning brush 312 can be used to clean the impurities on the filter element 2, thus preventing the holes on the filter element 2 from becoming clogged.

[0046] The support component 5 includes support components 5 installed at the four corners of the bottom of the box 1. The top and bottom ends of the four support components 5 are connected to the mounting brackets 41. The bottom ends of the support components 5 are all glued with anti-slip pads to prevent sliding.

[0047] Example 2 is an optimization based on Example 1, specifically:

[0048] The rinsing mechanism includes a water pump 323 installed on one side of the outer wall of the housing 1, and a pipe 321 including a water suction pipe and a water discharge pipe. The water suction end of the water pump 323 is connected to the water suction pipe, and one end of the water suction pipe is connected to the bottom end of one side of the housing 1. A water discharge pipe is installed on the inner wall of the top of the housing 1. One end of the water discharge pipe extends to the outside of the housing 1 and is connected to the water discharge end of the water pump 323. Spray nozzles 322 are installed at equal intervals on the part of the water discharge pipe located in the housing 1. A drain valve is installed on one side of the bottom end of the housing 1. An installation groove is opened on the outer wall of the bottom end of the housing 1, and a heating unit 324 is installed in the installation groove.

[0049] By adding water to the bottom of the chamber 1, the water is heated to boiling by turning on the heating unit 324, and the boiling water is pumped out by the water pump 323 to rinse the filter element 2 and disinfect the filter element 2.

[0050] Example 3 is an optimization based on Example 1, specifically:

[0051] Both sides of the inner wall of the housing 1 are equipped with first flanges 15, and fasteners 18 (e.g., locking bolts) are screwed onto the first flanges 15. The bottom end of the fasteners 18 is connected to a pressure block. Tightening the locking bolts can fix the filter element 2 using the pressure block. Opening the side door 17 and loosening the locking bolts can perform deep cleaning of the filter element 2, which is quite convenient.

[0052] Example 4 is an optimization based on Example 1, specifically:

[0053] Mounting frame 41 includes a base plate 411 and a connecting rod 412. The base plate 411 is a horizontal plate. The two ends of the connecting rod 412 are connected to the housing 1 and the horizontal plate, respectively. Mounting base 42 includes two movable columns 421 symmetrically inserted into the base plate 411. The top ends of the two movable columns 421 are connected to drive rods. The bottom ends of the drive rods are rotatably connected to the top ends of the base plate 411 through bearings. The top ends of the drive rods are equipped with handles 422. The bottom ends of the two movable columns 421 are connected to lifting plates 423. Rollers 44 are installed at the four corners of the bottom end of the lifting plates 423. By turning the drive rods, the lifting plates 423 can be lowered, so that the rollers 44 contact the ground, thereby causing the support rod to leave the ground and move the equipment.
