Technical Field

[0001] This invention relates to the field of coal mine ventilation equipment technology, specifically a coal mine ventilation and dust removal system. Background Technology

[0002] A coal mine is a rationally excavated space created by humans when mining geological strata rich in coal. It typically includes roadways, shafts, and mining faces.

[0026] 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.

[0027] The following description, with reference to the accompanying drawings, describes a coal mine ventilation and dust removal system according to an embodiment of the present invention.

[0028] like Figure 1-Figure 3 As shown, the coal mine ventilation and dust removal system 100 according to an embodiment of the present invention includes a housing 1, a filter assembly 2, a ventilation assembly 3, and a dust suppression assembly 4.

[0029] The housing 1 has a chamber 11, an air inlet 12, and an air outlet 13. Both the air inlet 12 and the air outlet 13 communicate with the chamber 11. The housing 1 is suitable for installation in a roadway, so that gas in the roadway flows into the chamber 11 through the air inlet 12 and flows out of the chamber 11. Specifically, as... Figure 1 As shown, the shell 1 is a rectangle extending in the left and right direction and can be installed in the tunnel. The left side of the shell 1 is provided with an air inlet 12 that communicates with the chamber 11. The gas in the tunnel can flow into the chamber 11 through the air inlet 12. The top plate of the shell 1 is provided with an air outlet 13 that communicates with the chamber 11, so that the gas in the shell 1 flows out of the chamber 11 through the air outlet 13.

[0030] The filter assembly 2 is located inside the chamber 11 and communicates with the air inlet 12 and the air outlet 13. The filter assembly 2 is used to filter the gas inside the housing 1. Specifically, as shown... Figure 2 As shown, the filter assembly 2 is installed inside the chamber 11 and is connected to the air inlet 12 and the air outlet 13. When the gas in the tunnel flows into the chamber 11 through the air inlet 12, the filter assembly 2 can filter the gas inside the housing 1 to remove impurities such as dust and harmful gases. The filtered gas then flows into the tunnel through the air outlet 13, effectively improving the air quality in the tunnel.

[0031] The ventilation assembly 3 is mounted on the housing 1 and is rotatable relative to the housing 1 in the vertical direction. The ventilation assembly 3 is connected to the air outlet 13 so that the gas flowing out of the air outlet 13 can flow into the roadway through the ventilation assembly 3. Specifically, as shown in the figure... Figure 1-Figure 3 As shown, the ventilation component 3 is installed on the housing 1 and rotates on the housing 1 in the up and down direction. The ventilation component 3 is connected to the air outlet 13. When the gas purified by the filter component 2 flows out of the air outlet 13, it will flow into the roadway through the ventilation component 3. The ventilation component 3 can be flexibly adjusted according to the actual airflow demand and direction of the roadway to increase the blowing range, facilitate air circulation, and ensure that the purified gas can be evenly and effectively delivered to every corner of the roadway, thereby improving the ventilation effect.

[0032] The dust suppression component 4 is mounted on the housing 1 and is rotatable relative to the housing 1 in the vertical direction. The dust suppression component 4 is used to spray dust-suppressing water to reduce dust in the roadway. Specifically, as shown... Figure 1 As shown, the dust suppression component 4 is mounted on the housing 1 and can rotate in the vertical direction. In actual operation, the dust suppression component 4 can flexibly adjust the spraying direction and angle according to the dust concentration and distribution in the roadway. By uniformly spraying dust suppression water, the water mist can fully contact the dust in the air, thereby wetting and increasing the weight of the dust particles, and finally settling them to achieve the purpose of efficient dust suppression in the roadway.

[0033] The coal mine ventilation and dust removal system 100 of this invention includes a filter assembly 2, a ventilation assembly 3, and a dust suppression assembly 4. The filter assembly 2 filters dust, harmful gases, and other impurities from the gas flowing into the chamber 11, improving air quality. The system flexibly adjusts its spray direction and angle according to the airflow requirements and direction in the roadway, allowing the purified gas to pass through the ventilation assembly 3 within the roadway, enhancing ventilation. Furthermore, based on the dust concentration and distribution within the roadway, the dust suppression assembly 4 flexibly adjusts its spray direction and angle, spraying dust-suppressing water to wet and increase the weight of dust particles, causing them to settle and achieving efficient dust suppression, thus improving the air quality in the mine.

[0034] In some embodiments, the filter assembly 2 includes a first water tank 21 and a first fan 22.

[0035] A first water tank 21 is located inside the housing 1, and the first water tank 21 stores filtered water. A first fan 22 is located inside the housing 1, with one end of the first fan 22 connected to the air inlet 12 to draw gas from the tunnel through the air inlet 12. The other end of the first fan 22 is connected to the first water tank 21 and is located inside the filtered water, so that the gas can be filtered through the filtered water. The upper end of the first water tank 21 is connected to the ventilation assembly 3, so that the filtered gas can flow out through the ventilation assembly 3. Specifically, as shown... Figure 2 As shown, the first water tank 21 is made of high-strength, corrosion-resistant high-quality materials to ensure that it can withstand the pressure and erosion of the filtered water during long-term use, thereby maintaining the stability and sealing of the structure of the first water tank 21. The first water tank 21 stores a sufficient amount of filtered water, which can effectively adsorb and neutralize pollutants such as dust particles and harmful gas molecules in the gas.

[0036] The first fan 22 is installed inside the casing 1. The inlet of the first fan 22 is connected to the air inlet 12 of the casing 1, and the outlet of the first fan 22 is connected to the first water tank 21. The gas in the tunnel is drawn into the first water tank 21 through the first fan 22, so that the filtered water adsorbs and precipitates the impurities in the gas in the tunnel, thereby purifying the gas in the tunnel.

[0037] In some embodiments, the filter assembly 2 further includes a housing 23 and a plurality of filter screens 24. The housing 23 is disposed within the housing 1, and the plurality of filter screens 24 are all disposed within the housing 23 and spaced apart in the vertical direction. The lower end of the housing 23 communicates with the upper end of the first water tank 21 so that the gas filtered by the first water tank 21 flows into the housing 23 and is filtered by the filter screens 24. The upper end of the housing 23 communicates with the ventilation assembly 3 so that the gas filtered by the filter screens 24 flows out through the ventilation assembly 3. Specifically, as shown... Figure 2 As shown, the housing 23 is a rectangular box housed within the casing 1, and is positioned on top of the first water tank 21. Multiple filter screens 24 are disposed inside the housing 23, spaced apart along the vertical direction. The bottommost filter screen 24 has a relatively large pore size, primarily used to intercept larger dust particles that may remain after filtration by the first water tank 21, serving as preliminary filtration and protecting the upper filter screens 24. As the filter screens 24 rise in position, their pore size gradually decreases, continuously improving filtration precision and enabling the sequential removal of finer dust particles and particulate impurities. This enhances the dust adsorption capacity and filtration effect of the filter screens 24, while also providing good air permeability to ensure smooth gas passage and prevent clogging of the filter screens 24 from affecting the normal operation of the system.

[0038] The lower end of the housing 23 is connected to the upper end of the first water tank 21. After the gas undergoes preliminary purification by filtered water in the first water tank 21, it carries a small amount of residual water vapor and tiny impurities and rises to the lower end of the housing 23, flowing into the interior of the housing 23 through the pipe. At this point, the gas begins to undergo multi-stage fine filtration through various filter screens 24, thereby intercepting dust and impurities in the gas layer by layer, further purifying and refining the gas. The upper end of the housing 23 is connected to the ventilation assembly 3, and the filtered gas flows into the ventilation assembly 3 and is then transported into the tunnel through the ventilation assembly 3.

[0039] In some embodiments, the coal mine ventilation and dust removal system 100 further includes a dust suction hood 5 and a dust suction pipe 6.

[0040] The dust collection hood 5 is located inside the housing 1 and covers the air inlet, so that air in the tunnel flows into the dust collection hood 5 through the air inlet. Specifically, as shown... Figure 1 and Figure 3 As shown, the dust hood 5 is made of high-strength, wear-resistant metal alloy and undergoes a special surface treatment process, giving it anti-corrosion and anti-static properties to adapt to the harsh working environment of underground coal mines and ensure long-term stable operation. The dust hood 5 is housed inside the casing 1, positioned above and tightly fitted to the air inlet to prevent gas leakage. When the gas in the mine roadway contains a large amount of dust and harmful substances, the gas flows into the dust hood 5 through the air inlet, providing a sufficient air source for subsequent purification treatment.

[0041] The suction pipe 6 includes a first pipe 61 and a second pipe 62. The two ends of the first pipe 61 are connected to the suction hood 5 and the first fan 22, respectively, so that air inside the suction hood 5 flows into the first fan 22 through the first pipe 61. One end of the second pipe 62 is connected to the first fan 22, and the other end of the second pipe 62 passes through the first water tank 21 and is embedded in the filtered water, so that air inside the first fan 22 flows into the filtered water through the second pipe 62. Specifically, as... Figure 2 As shown, the first pipe 61 is disposed between the dust collection hood 5 and the first fan 22, and both ends of the first pipe 61 are connected to the inlets of the dust collection hood 5 and the first fan 22, respectively. The first fan 22 draws the gas in the dust collection hood 5 into the first fan 22 through the first pipe 61. The left end of the second pipe 62 is connected to the outlet of the first fan 22, and the right end of the second pipe 62 passes through the first water tank 21 and is located in the filtered water, so that the gas in the first fan 22 is passed into the filtered water, and the gas flows into the filtered water for preliminary filtration.

[0042] In some embodiments, the coal mine ventilation and dust removal system 100 further includes a conveying pipe 7, one end of which passes through the housing 1 and communicates with the lower end of the box 23, and the other end of which extends outside the housing 1 so that gas in the roadway flows into the box 23 through the conveying pipe 7. Specifically, as Figure 2 As shown, the conveying pipe 7 is installed inside the housing 1. The inlet of the conveying pipe 7 is located outside the box 23, and the outlet of the conveying pipe 7 is connected to the lower end of the box 23, so that the gas in the tunnel flows into the box 23 through the conveying pipe 7 and is filtered by the filter screen 24 inside the box 23.

[0043] In some embodiments, the ventilation assembly 3 includes a mounting base 31, a duct 32, and a second fan 33.

[0044] Mounting base 31 is mounted on housing 1 and is rotatable relative to housing 1 in the vertical direction. Air duct 32 is mounted on mounting base 31 and is rotatable with mounting base 31 in the vertical direction. One end of air duct 32 is connected to filter assembly 2 so that gas flowing out of filter assembly 2 can be discharged into the tunnel through air duct 32. Specifically, as... Figure 1 and Figure 3 As shown, the mounting base 31 is rotatably mounted on the upper surface of the housing 1, and the air duct 32 is mounted on the mounting base 31, thereby driving the air duct 32 to rotate through the mounting base 31. The inlet of the air duct 32 is connected to the upper end of the box 23 through a pipe, so that the gas filtered by the filter screen 24 flows into the air duct 32 through the pipe and is transported to the tunnel through the air duct 32.

[0045] The second fan 33 is installed inside the ventilation duct 32. The second fan 33 is used to extract gas from the ventilation duct 32 and transport the gas into the roadway. Specifically, as shown... Figure 1 and Figure 3As shown, the second fan 33 is installed inside the air duct 32. When it is necessary to filter the gas in the tunnel, the gas filtered by the box 23 can be extracted out of the air duct 32 by the second fan 33.

[0046] In some embodiments, the coal mine ventilation and dust removal system 100 further includes a drive member 34, which is disposed within the housing 1 and connected to the mounting base 31, so that the drive member drives the mounting base 31 to rotate. Specifically, as Figure 1 and Figure 3 As shown, the drive unit 34 can be a motor and is mounted on the housing 1. A disc 35 is sleeved on the top of the output shaft of the drive unit 34. A connecting rod 36 is rotatably mounted on the outer wall of the top of the disc 35. A fixing rod 37 is rotatably mounted on the other end of the connecting rod 36, and the other end of the fixing rod 37 is connected to the mounting base 31. The drive unit drives the mounting base 31 to rotate through the disc 35, the connecting rod 36 and the fixing rod 37, thereby increasing the air blowing range and facilitating air circulation.

[0047] In some embodiments, the dust suppression assembly 4 includes a second water tank 41, an atomizing nozzle 42, and a water pump 43.

[0048] The second water tank 41 is located on the housing 1 and stores dust-reducing water. The atomizing nozzle 42 is located on the ventilation assembly 3 so that the ventilation assembly 3 can drive the atomizing nozzle 42 to rotate. Specifically, as shown in the figure... Figure 1 As shown, the second water tank 41 is installed on the top surface of the box body 23. The second water tank 41 is filled with dust-suppressing water. The physical and chemical nozzle is fixedly installed on the outer circumference of the air duct 32, thereby driving the atomizing nozzle 42 to rotate through the air duct 32.

[0049] A water pump 43 is mounted on and connected to the second water tank 41. The water pump 43 is also connected to the atomizing nozzle 42, allowing the dust-suppressing water in the second water tank 41 to flow into the atomizing nozzle 42 via the water pump 43. Specifically, as... Figure 1 As shown, the water pump 43 is installed on the second water tank 41. The inlet of the water pump 43 is connected to the dust-suppressing water in the second water tank 41 through a pipe, and the outlet of the water pump 43 is connected to the atomizing nozzle 42 through a pipe, so that the dust-suppressing water flows into the atomizing nozzle 42 through the water pump 43 and is sprayed into the tunnel through the atomizing nozzle 42.

[0050] In some embodiments, the coal mine ventilation and dust removal system 100 further includes a lighting component 8, which is disposed on the housing 1 and is used for illuminating the roadway. Specifically, as Figure 1 As shown, the lighting component 8 is a lighting lamp and is located on the left end face of the housing 1. When the lighting in the tunnel is insufficient, the lighting component 8 can be turned on to illuminate the tunnel.

[0051] In some embodiments, the coal mine ventilation and dust removal system 100 further includes a transport vehicle 9, with the housing 1 mounted on the transport vehicle 9 so that the transport vehicle 9 can move the housing 1. Specifically, as Figure 1 As shown, the transport vehicle 9 includes a base plate 91, pulleys 93 and handle 92. The base plate 91 is a horizontal plate extending in the left and right direction. There are multiple pulleys 93, all of which are arranged below the base plate 91. The handle 92 is located at the right end of the base plate 91 and on the upper surface of the base plate 91. The housing 1 is arranged on the base plate 91, so that the base plate 91 can be moved in the tunnel by pushing the handle 92.

[0052] The working principle of the coal mine ventilation and dust removal system 100 in this embodiment of the invention is as follows: The first fan 22 is started, and through the cooperation of the dust suction hood 5 and the dust suction pipe 6, the dust in the mine is sucked into the first water tank 21. The air is purified by the adsorption and sedimentation of the water in the first water tank 21. Simultaneously, the second fan 33 is started, and driven by the second fan 33, outside air is sucked into the housing 23 through the conveying pipe 7. Air filtered by the first water tank 21 also enters the housing 23 through the pipe. The air entering the housing 23 is filtered by the filter screen 24 and sprayed into the mine through the air duct 32 via the flexible hose. To dissipate heat and accelerate air circulation within the mine, the drive unit is activated, causing the disc to rotate. The disc, via a connecting rod, causes the mounting base 31 on the fixed rod to rotate back and forth, increasing the airflow range of the ventilation duct 32. The water pump 43 is then activated, delivering water from the second water tank 41 to the atomizing nozzle 42 via a hose. The water is then atomized and sprayed into the mine, reducing airborne dust and effectively lowering the dust concentration within the mine. This also facilitates the introduction of air into the mine, accelerating air circulation and effectively preventing safety hazards caused by workers inhaling large amounts of dust or oxygen deficiency.

[0053] The coal mine ventilation and dust removal system 100 of this invention can suck up dust from the air in the mine and recycle it. It can also introduce outside air into the mine to improve the air circulation in the mine, effectively avoid workers from lacking oxygen or inhaling a large amount of dust, which could cause safety hazards. It improves the working environment of the workers. The combination of the first water tank 21, water pump 43, first hose and atomizing nozzle 42 makes it easier to reduce the dust floating in the air in the mine. It further improves the working environment. The combination of the first rotating motor, disc, connecting rod and fixed rod makes it easier to drive the air duct 32 to rotate, which increases the blowing range of the air duct 32.
