Description

Technical Field

[0001] This utility model relates to ventilation and dust suppression equipment for coal mines. Background Technology

[0002] In today's energy-intensive society, coal mines are typically quite deep in order to obtain more resources. This results in the presence of various harmful gases in deep mines, including carbon monoxide, hydrogen sulfide, sulfur dioxide, nitrogen dioxide, nitrogen, hydrogen, and methane. These gases can easily cause poisoning, fires, and explosions. Therefore, for safe mining, mines often need to be ventilated to introduce large amounts of fresh air and dilute and release harmful gases.

[0003] Existing coal mine ventilation and dust suppression equipment typically uses filters to remove dust and pollutants from the air. However, after a period of use, the filters easily become saturated, leading to clogging and reduced filtration efficiency, making it difficult to continuously remove dust and particulate matter from the air. Cleaning components are then installed on one side of the filter to remove particles adsorbed on its surface. However, this one-sided cleaning not only fails to thoroughly remove fine particles attached to the filter surface and hidden deep within the mesh, but also easily causes uneven wear due to the one-sided cleaning, reducing the filter's lifespan and increasing the replacement frequency. Utility Model Content

[0004] This invention addresses the problem that filters typically remove dust and pollutants from the air, but after a period of use, they easily become saturated, leading to clogging and reduced filtration efficiency, making it difficult to continuously remove dust and particulate matter. While a cleaning component is installed on one side of the filter to remove adsorbed particles, this one-sided cleaning not only fails to thoroughly remove fine particles attached to the filter surface and hidden deep within the mesh, but also causes uneven wear, reducing the filter's lifespan and increasing replacement frequency. Therefore, this invention provides a coal mine ventilation and dust suppression device.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a coal mine ventilation and dust suppression device, including a housing. An upper plate and a lower plate are fixedly installed inside the housing. A first threaded rod and two second threaded rods are rotatably connected between the upper and lower plates via bearings. The first threaded rod and the two first threaded rods extend to the top of the upper plate. A motor is fixedly installed on the housing, and the output shaft of the motor extends into the housing and is fixedly connected to the first threaded rod. A driven pulley is fixedly installed on each of the two second threaded rods. Two main pulleys are sleeved on the first threaded rod, and the two main pulleys are connected to the driven pulleys via belts. A first movable block is threadedly connected to the first threaded rod, and two connecting plates are fixedly installed on the first movable block. A second movable block is threadedly connected to each of the two second threaded rods, and a connecting plate is fixedly installed on one side of each of the two second movable blocks. A cleaning brush is provided on one side of each of the connecting plates. Multiple guide rods are fixedly installed between the upper and lower plates, and the first movable block and the two second movable blocks are slidably connected to the guide rods.

[0007] In this technical solution, two side plates are fixedly installed inside the box, and air vents are provided on both side plates.

[0008] In this technical solution, there are two limiting grooves on the upper plate, and a first filter screen and a second filter screen are provided between the upper plate and the lower plate. Filter frames are provided around both the first filter screen and the second filter screen.

[0009] In this technical solution, both filter frames are slidably connected to the limiting groove, and a second handle is fixedly installed on both filter frames.

[0010] In this technical solution, the housing is connected to an air inlet pipe and an air outlet pipe. An air intake fan and an exhaust fan are fixedly installed inside the air inlet pipe and the air outlet pipe, respectively. Both the air inlet pipe and the air outlet pipe are threaded with mounting covers, and ventilation meshes are provided on both mounting covers.

[0011] In this technical solution, the interior of the housing is equipped with two sets of dust suppression components. The dust suppression components include atomizing nozzles, a diversion pipe, and a water pump. The diversion pipe is fixedly installed inside the housing, and multiple atomizing nozzles distributed at equal intervals are connected to the diversion pipe. The water pump is fixedly installed on the housing, and a delivery pipe and a suction pipe are respectively connected to both ends of the water pump. One end of the suction pipe is connected to the bottom end of the housing, and one end of the delivery pipe extends into the housing and connects to the diversion pipe.

[0012] In this technical solution, two fixed pipes are fixedly installed on the inner wall of the box, and a water filter screen is provided on each of the two fixed pipes. One end of each of the two water pumping pipes extends into the interior of the fixed pipe.

[0013] In this technical solution, a water outlet pipe is connected to one side of the box, and a valve is installed on the water outlet pipe.

[0014] In this technical solution, the lower plate is provided with multiple discharge ports, and a collection box is provided inside the box below the lower plate, with a first handle fixedly installed on the collection box.

[0015] In this technical solution, four brake casters are fixedly installed at the bottom of the box.

[0016] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0017] The positive and progressive effects of this utility model are as follows:

[0018] The aforementioned coal mine ventilation and dust suppression equipment, by starting the motor, causes multiple connecting plates to move the cleaning brushes, cleaning both sides of the first and second filter screens. This not only more comprehensively removes fine particles attached to the filter screen surface and hidden deep within the mesh, avoiding a decrease in filtration efficiency due to clogging and improving the filtration effect of the filter screen, but also helps to evenly remove particles from the filter screen surface, avoiding uneven wear caused by one-sided cleaning, extending the service life of the filter screen, reducing the replacement frequency, lowering maintenance costs, and ensuring that the device can continuously and efficiently remove dust and pollutants from the air.

[0019] By setting up two sets of dust suppression components and simultaneously starting two water pumps, the atomizing nozzles at the air inlet duct can pre-treat the external air entering the chamber, effectively removing suspended particulate matter such as coal dust and rock dust. It can also pre-moisten the air particles, making them easier for the first and second filters to capture, thus enhancing the filtration effect and extending the filter lifespan. Meanwhile, the atomizing nozzles at the air outlet duct perform secondary dust suppression on the filtered air, further removing any remaining fine particles and ensuring cleaner exhaust air, further reducing dust emissions. By setting up two sets of dust suppression components, the airflow path inside the chamber is ensured to receive sufficient dust suppression, helping to maintain cleanliness inside the chamber, reducing dust accumulation, and thus optimizing airflow.

[0020] The water after spraying is filtered through a filter screen to remove impurities and particulate matter, thus achieving water resource recycling, reducing the consumption of fresh water and the discharge of wastewater, reducing water waste, and improving resource utilization efficiency.

Both second threaded rods 26 are threadedly connected to second movable blocks 30. One side of each of the two second movable blocks 30 is fixedly installed with a connecting plate 31. One side of each of the multiple connecting plates 31 is provided with a cleaning brush 29. Multiple guide rods 33 are fixedly installed between the upper plate 5 and the lower plate 40. The first movable block 32 and the two second movable blocks 30 are slidably connected to the guide rods 33.

[0034] In this technical solution, two side plates 7 are fixedly installed inside the housing 1, and air vents 8 are provided on both side plates 7.

[0035] In this technical solution, the upper plate 5 has two limiting grooves 28, and a first filter screen 22 and a second filter screen 25 are provided between the upper plate 5 and the lower plate 40. Filter frames 34 are provided around the first filter screen 22 and the second filter screen 25.

[0036] In this technical solution, both filter frames 34 are slidably connected to the limiting groove 28, and a second handle 37 is fixedly installed on both filter frames 34.

[0037] The housing 1 is connected to an air inlet pipe 13 and an air outlet pipe 38. An air intake fan 15 and an exhaust fan 39 are fixedly installed inside the air inlet pipe 13 and the air outlet pipe 38, respectively. Both the air inlet pipe 13 and the air outlet pipe 38 are threadedly connected to a mounting cover 14, and both mounting covers 14 are provided with ventilation mesh 16.

[0038] In this technical solution, the interior of the housing 1 is provided with two sets of dust suppression components. The dust suppression components include atomizing nozzles 12, a diversion pipe 11, and a water pump 9. The diversion pipe 11 is fixedly installed inside the housing 1, and multiple atomizing nozzles 12 are connected to the diversion pipe 11 at equal intervals. The water pump 9 is fixedly installed on the housing 1, and the two ends of the water pump 9 are respectively connected to a delivery pipe 10 and a suction pipe 35. One end of the suction pipe 35 is connected to the bottom end of the housing 1, and one end of the delivery pipe 10 extends into the interior of the housing 1 and is connected to the diversion pipe 11.

[0039] In this technical solution, two fixed pipes 27 are fixedly installed on the inner wall of the box 1, and a water filter screen 20 is provided on each of the two fixed pipes 27. One end of each of the two water pumping pipes 35 extends into the interior of the fixed pipe 27.

[0040] In this technical solution, a water outlet pipe 17 is connected to one side of the box body 1, and a valve 18 is provided on the water outlet pipe 17. This water outlet pipe 17 can be used for water inlet and water outlet.

[0041] In this technical solution, the lower plate 40 is provided with multiple discharge ports 24, and a collection box 21 is provided inside the box 1 below the lower plate 40. A first handle 36 is fixedly installed on the collection box 21.

[0042] In this technical solution, four brake casters 19 are fixedly installed at the bottom of the housing 1.

[0043] In use, all electrical components mentioned in this application are externally connected to a power source and control switch. The device is moved or fixed in a suitable area by the brake caster 19. The inlet fan 15 is turned on to introduce external air into the housing 1, which can form an airflow circulation from the outside to the housing 1. The exhaust fan 39 is turned on to exhaust the filtered air to the external environment. The exhaust fan 39 and the inlet fan 15 work together to promote air convection inside the housing 1, which helps to accelerate the settling and filtration of dust particles and improve purification efficiency.

[0044] When motor 3 is started, its output shaft drives the first threaded rod 23 to rotate. The first threaded rod 23 drives two driven pulleys 6 to rotate via the main pulley 4. Both driven pulleys 6 drive the second threaded rod 26 to rotate. With the cooperation of multiple guide rods 33, the first movable block 32 and the two second movable blocks 30 move up and down along the surfaces of the second threaded rod 26 and the first threaded rod 23, respectively. This causes multiple connecting plates 31 to drive the cleaning brush 29 to move, cleaning both sides of the first filter screen 22 and the second filter screen 25. This ensures that the first filter screen 22 and the second filter screen 25 remain unobstructed, avoiding a decrease in filtration efficiency due to clogging. This ensures that the device can continuously and efficiently remove dust and pollutants from the air, extend its service life, and reduce the cost of frequent filter screen replacements. At the same time, cleaning the filter screens maintains their filtration performance and improves the purification effect, helping to ensure the continuous and stable operation of the purification and dust removal device. The cleaned dust enters the collection box through the discharge port, which can easily collect the dust that falls during the cleaning process and avoid secondary pollution.

[0045] Simultaneously, two water pumps 9 are activated. Both water pumps 9 transport water from the bottom of the housing 1 through the pumping pipe 35 to the distribution pipe 11 through the delivery pipe 10. The water is then sprayed onto the air through multiple atomizing nozzles 12. The atomizing nozzles at the air inlet pipe can pre-treat the external air entering the housing 1 to reduce dust, effectively removing suspended particulate matter such as coal dust and rock dust. They can also pre-moisten the particulate matter in the air, making it easier for it to be captured by the first and second filters, thereby enhancing the filtration effect and extending the service life of the filters. The atomizing nozzles at the air outlet pipe 38 perform secondary dust reduction on the filtered air, which can further remove any remaining tiny particles, ensuring that the exhaust air is cleaner and further reducing dust emissions. By setting up two sets of dust reduction components, it can be ensured that the air is fully treated for dust reduction in the circulation path inside the housing 1, which helps to keep the inside of the housing 1 clean, reduce dust accumulation, and optimize the air circulation effect. Most of the dust after spraying will settle to the bottom of the housing 1 by gravity, thereby achieving air purification.

[0046] By pulling the second handle 37, the filter frame 34 moves the first filter screen 22 or the second filter screen 25 out of the box. Users can replace the first filter screen 22 and the second filter screen 25 without complicated disassembly, which improves the convenience of equipment maintenance and ensures that the filter screen will not be clogged or damaged due to long-term use, thereby extending the service life of the entire ventilation and dust suppression equipment.

[0047] The water after spraying is filtered through the filter screen 20 to remove impurities and particulate matter, thereby achieving water resource recycling, reducing the consumption of fresh water and the discharge of wastewater, reducing water waste, and improving resource utilization efficiency.

[0048] The advantages of this application are:

[0049] 1. By starting the motor, multiple connecting plates 29 drive the cleaning brushes 26 to move, cleaning both sides of the first filter screen 25 and the second filter screen 28. This not only removes fine particles attached to the surface of the filter screen and hidden deep in the mesh, avoiding the decrease in filtration efficiency due to clogging and improving the filtration effect of the filter screen, but also helps to remove particles on the surface of the filter screen evenly, avoiding uneven wear caused by cleaning one side, extending the service life of the filter screen, reducing the replacement frequency, reducing maintenance costs, and ensuring that the device can continuously and efficiently remove dust and pollutants from the air.

[0050] 2. By setting up two sets of dust suppression components and simultaneously starting two water pumps 9, the atomizing nozzles 12 at the air inlet pipe 13 can pre-treat the external air entering the housing 1, effectively removing suspended particulate matter in the air, such as coal dust and rock dust. It can also pre-moisten the particulate matter in the air, making it easier for it to be captured by the first filter screen 22 and the second filter screen 25, thereby enhancing the filtration effect and extending the service life of the filter screens. The atomizing nozzles 12 at the air outlet pipe 38 perform secondary dust suppression on the filtered air, which can further remove any possible residual small particles, ensuring that the discharged air is cleaner and further reducing dust emissions. By setting up two sets of dust suppression components, it can be ensured that the air is fully treated for dust suppression in the circulation path inside the housing 1, which helps to keep the inside of the housing 1 clean, reduce dust accumulation, and thus optimize the air circulation effect. Most of the dust after spraying will settle to the bottom of the housing 1 by gravity, thereby achieving air purification.

[0051] 3. By filtering the sprayed water through the filter screen 20, impurities and particulate matter are removed, water resources are recycled, fresh water consumption and wastewater discharge are reduced, water waste is reduced, and resource utilization efficiency is improved.

[0052] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
