Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0031] A nozzleless air flow purification device for coal mines provided by an embodiment of the present invention. The nozzleless air flow purification device for coal mines includes: an outer spray pipe 1 of an atomized water curtain; an inner driving pipe 11 of atomized water curtain compressed air is arranged inside the outer spray pipe 1 of the atomized water curtain, and the cavity formed by the outside of the inner driving pipe 11 of the atomized water curtain compressed air and the inner side of the outer spray pipe 1 of the atomized water curtain is an atomization chamber; wherein, a cleaning component is arranged in the atomization chamber, and the cleaning component can clean the scale in the atomization chamber; a moving component is arranged on one side of the outer spray pipe 1 of the atomized water curtain close to the cleaning component, and the moving component can drive the cleaning component to reciprocate in the atomization chamber; a plurality of fixing components are arranged on the outside of the outer spray pipe 1 of the atomized water curtain, and the fixing components can facilitate the installation and layout of the outer spray pipe 1 of the atomized water curtain; one end of the outer spray pipe 1 of the atomized water curtain is connected with a connector 12, and the top of the connector 12 is connected with a rapid connector 13 for underground static pressure water. One end of the inner driving pipe 11 of the atomized water curtain compressed air close to the connector 12 penetrates through the connector 12 and is connected with a rapid connector 14 for downward compressed air. One end of the outer spray pipe 1 of the atomized water curtain far from the connector 12 is connected with a backwashing rapid connector 15. A plurality of outer pipe nozzles 16 are arranged on the outside of the outer spray pipe 1 of the atomized water curtain along the axial direction. A plurality of inner pipe nozzles 17 are arranged on the outside of the inner driving pipe 11 of the atomized water curtain compressed air along the axial direction, and the outer pipe nozzles 16 and the inner pipe nozzles 17 are arranged in a staggered distribution.

[0032] It should be noted that: The atomized water curtain outer spray pipe 1 and the atomized water curtain compressed air inner drive pipe 11 together form an atomization chamber. Through the driving action of the compressed air inner drive pipe 11, the atomization of water is achieved. The cleaning component is located inside the atomization chamber and is used to clean the scale inside the chamber. Driven by the moving component, the cleaning component reciprocates inside the atomization chamber to clean the scale inside the chamber, ensuring the normal operation of the device. The fixing component is used to fix the atomized water curtain outer spray pipe 1 in place, facilitating the installation and layout of the device. Through the connector 12 and various quick connectors, the quick connection of the device with the underground static pressure system, the downward compressed air system, and the backwashing system is realized, facilitating operation and maintenance. The underground static pressure water quick connector 13 is used to quickly connect to the underground static pressure system. Through the underground static pressure water quick connector 13, the water pressure provided by the underground static pressure system is introduced into the atomized water curtain outer spray pipe 1, providing the required water source and pressure for the atomization process. The downward compressed air quick connector 14 is used to quickly connect to the downward compressed air system. Through the downward compressed air quick connector 14, the air pressure provided by the downward compressed air system is introduced into the atomized water curtain compressed air inner drive pipe 11, providing the required driving force for the atomization process. The backwashing quick connector 15 is used to connect to the backwashing system to realize the backwashing operation of the atomized water curtain outer spray pipe 1. Through the backwashing quick connector 15, the water flow provided by the backwashing system is introduced into the atomized water curtain outer spray pipe 1 to wash the scale and impurities inside the pipe, keeping the inside of the pipe clean and unobstructed. The outer pipe nozzles 16 and the inner pipe nozzles 17 of the atomized water curtain outer spray pipe 1 are staggered. Through the staggered distribution of the outer pipe nozzles 16 and the inner pipe nozzles 17, the water mist can be more evenly distributed inside the atomization chamber, improving the air flow purification effect. The staggered distribution of the nozzles can increase the coverage area of the water mist, enabling more air flow to be purified, and can reduce the accumulation of scale at the nozzles, reducing the risk of blockage. The diameter of the outer pipe nozzles 16 is smaller than that of the inner pipe nozzles 17. Through the principle that the flow rate of high-pressure gas increases at small apertures, the static pressure water is driven to spray and atomize. Since the diameter of the inner pipe nozzles 17 is smaller, the air flow will accelerate when passing through. When the high-speed air flow meets the water droplets ejected from the outer pipe nozzles 16, the water droplets can be effectively broken into smaller water mist particles. The water pressure introduced through the underground static pressure water quick connector 13 causes the water to be ejected from the outer pipe nozzles 16, and the air pressure introduced through the downward compressed air quick connector 14 causes the air flow to be ejected from the inner pipe nozzles 17. After the water is ejected from the outer pipe nozzles 16, it meets the air flow ejected from the inner pipe nozzles 17, forming fine water mist particles inside the atomization chamber. The formed water mist particles flow along with the air flow to adsorb and purify the dust and harmful gases in the air flow. When the high-speed gas passes through the inner pipe nozzles 17, due to the restriction of the aperture, its kinetic energy will increase. Even if part of the gas is intercepted at the pipe wall and its speed decreases, its kinetic energy is still sufficient to break the water droplets ejected from the outer pipe nozzles 16 into smaller water mist particles. These three quick connectors are respectively connected to the underground static pressure system, the downward compressed air system, and the backwashing system, providing the required water pressure, air pressure, and backwashing function for the normal operation of the coal mine nozzleless air flow purification device.Through the connection of these quick connectors, the rapid installation, operation, and maintenance of the device are realized, improving work efficiency and reliability.

[0033] In an embodiment of the present invention, the cleaning component includes a first support ring frame 2 slidably connected to the outer side of the inner driving pipe 11 of the atomized water curtain compressed air. A first annular groove 21 is formed on the outer side of the first support ring frame 2, and an N - pole magnet 22 is installed in the first annular groove 21. Both sides of the first support ring frame 2 are connected with first annular brush plates 23. A plurality of inner pipe outer wall brushes 24 are connected to the inner sides of the two first annular brush plates 23, and the inner pipe outer wall brushes 24 are equidistantly distributed along the axis of the first annular brush plate 23. A plurality of outer pipe inner wall brushes 25 are connected to the outer sides of the first annular brush plates 23, and the outer pipe inner wall brushes 25 are equidistantly distributed along the axis of the first annular brush plate 23. A plurality of water flow - through holes 26 are formed on the inner side of the first support ring frame 2. The moving component includes a second support ring frame 3 slidably connected to the outer side of the outer spray pipe 1 of the atomized water curtain, and the second support ring frame 3 is located on the side close to the first support ring frame 2. A second annular groove 31 is formed on the inner side of the second support ring frame 3, and an S - pole magnet 32 is installed in the second annular groove 31. Both sides of the second support ring frame 3 are connected with second annular brush plates 33. A plurality of outer pipe outer wall brushes 34 are connected to the inner sides of the two second annular brush plates 33, and the outer pipe outer wall brushes 34 are equidistantly distributed along the axis of the second annular brush plate 33. A plurality of holding parts 35 are connected to the outer side of the second support ring frame 3, and the holding parts 35 are equidistantly distributed along the axis of the second support ring frame 3. The outer side of the N - pole magnet 22 attracts the inner side of the S - pole magnet 32.

[0034] It should be noted that: The first support ring frame 2 is slidably connected to the outer side of the atomized water curtain compressed air inner drive pipe 11. As the main support structure of the cleaning component, it drives other components to perform cleaning operations. The first annular groove 21 is located on the outer side of the first support ring frame 2, and the N-pole magnet 22 is installed in the first annular groove 21 for interacting with the S-pole magnet in the moving component to realize the reciprocating movement of the cleaning component. The first annular brush plate 23 is the main brushing component of the cleaning component. The scale in the atomizing chamber is cleaned by the inner tube outer wall brush 24 and the outer tube inner wall brush 25. The inner tube outer wall brush 24 is used to clean the outer side wall of the atomized water curtain compressed air inner drive pipe 11 to remove the attached scale, and the outer tube inner wall brush 25 is used to clean the inner side wall of the atomized water curtain outer spray pipe 1 to remove the attached scale. The water flow holes 26 are opened on the inner side of the first support ring frame 2 to allow water to pass through, ensuring that the water flow in the atomizing chamber will not be overly obstructed during the cleaning process and maintaining the normal atomizing process. The second support ring frame 3 is slidably connected to the outer side of the atomized water curtain outer spray pipe 1 and is located on the side close to the first support ring frame 2. As the main support structure of the moving component, it drives the cleaning component to perform reciprocating movement. The second annular groove 31 is located on the inner side of the second support ring frame 3, and the S-pole magnet 32 is installed in the second annular groove 31 for interacting with the N-pole magnet 22 in the cleaning component to realize the reciprocating movement of the cleaning component. The second annular brush plate 33 is the auxiliary brushing component of the moving component. The outer side wall of the atomized water curtain outer spray pipe 1 is cleaned by the outer tube outer wall brush 34. The gripping parts 35 are connected to the outer side of the second support ring frame 3 and are evenly distributed along the axis of the second support ring frame 3. This facilitates the operator to grip and move the second support ring frame 3 for cleaning and maintenance operations. The outer side of the N-pole magnet 22 attracts the inner side of the S-pole magnet 32. Through the interaction of the magnets, the connection between the first support ring frame 2 and the second support ring frame 3 is realized. During the movement through the gripping parts 35, the inner tube outer wall brush 24 and the outer tube inner wall brush 25 respectively brush the outer side wall of the atomized water curtain compressed air inner drive pipe 11 and the inner side wall of the atomized water curtain outer spray pipe 1 to remove the attached scale. At the same time, the outer tube outer wall brush 34 cleans the outer side wall of the atomized water curtain outer spray pipe 1. The cleaning component and the moving component can work together effectively to clean the scale inside and outside the atomizing chamber, maintain the normal operation of the device, and improve the air flow purification effect. The mutual attraction between the N-pole magnet 22 and the S-pole magnet 32 provides a non-contact driving force. Since the magnetic force acts evenly on the support ring frame, it can provide sufficient driving force to overcome the friction between the brush and the pipe wall to realize stable sliding. The equidistant distribution design of the brushes can reduce the resistance during the sliding process. Since the brushes are equidistantly distributed, their contact with the pipe wall during the sliding process is uniform and will not form local friction hot spots, thus reducing the sliding resistance. The equidistantly distributed brushes reduce the uneven friction force during the sliding process and can make the sliding more stable.

[0035] In an embodiment of the present invention, the fixing component includes a mounting plate 4, and the mounting plate 4 is located at the outer top of the atomized water curtain outer spray pipe 1. The mounting plate 4 has a cross structure. Fixing holes 41 are provided at the four corners of the mounting plate 4. A fixing rod 42 is provided in each fixing hole 41. Support rods 43 are connected to both sides of the bottom of the mounting plate 4. The bottoms of the two support rods 43 are both connected to a support plate 44. A contact plate 45 is provided at the bottom of the support plate 44, and the bottom of the contact plate 45 is in contact with the outer top of the atomized water curtain outer spray pipe 1. Guide rods 46 are connected to both sides of the top of the contact plate 45. The tops of the two guide rods 46 penetrate through the support plate 44 and are connected with limit blocks. Return springs 47 are sleeved on the outer sides of the bottoms of the two guide rods 46, and the return springs 47 are located between the contact plate 45 and the support plate 44. The fixing component further includes a U-shaped frame 5, and the U-shaped frame 5 is located at the outer bottom of the atomized water curtain outer spray pipe 1. Bending parts 51 are provided at the tops of both sides of the U-shaped frame 5. A card slot 52 for the bending parts 51 to pass through is provided on the support plate 44. Pressing parts 53 are installed on both sides of the U-shaped frame 5, and the pressing parts 53 are located below the bending parts 51.

[0036] It should be noted that: The mounting plate 4 is in a cross structure, and fixing holes 41 are provided at all four corners. As the main support structure of the fixing component, it is fixed in place through the fixing holes 41 and the fixing rods 42. The support rods 43 are connected to both sides of the bottom of the mounting plate 4, and the support plates 44 are connected to the bottoms of the support rods 43 to provide support for the abutting plate 45, ensuring that the abutting plate 45 can stably abut against the outer top of the atomized water curtain outer spray pipe 1. Through the abutting action, the atomized water curtain outer spray pipe 1 is fixed in place to prevent it from moving. The guide rods 46 are connected to both sides of the top of the abutting plate 45, penetrate through the support plate 44 at the top and are connected with limit blocks, providing a guiding effect for the abutting plate 45 to ensure its stability during the up and down movement. The limit blocks prevent the guide rods 46 from disengaging from the support plate 44. The return spring 47 is sleeved on the outer bottom of the guide rod 46 and is located between the abutting plate 45 and the support plate 44. When the abutting plate 45 is forced to move upward, the return spring 47 is compressed to store elastic potential energy. When the external force disappears, the return spring 47 releases the elastic potential energy to push the abutting plate 45 downward to closely abut against the outer top of the atomized water curtain outer spray pipe 1. Through the restoring force provided by the return spring 47, the abutting plate 45 can always maintain a close abutting state with the atomized water curtain outer spray pipe 1 to prevent it from moving during operation. The setting of the return spring 47 will not overly squeeze the atomized water curtain outer spray pipe 1 to prevent the atomized water curtain outer spray pipe 1 from deforming or being damaged, affecting the normal operation of the device. The U-shaped frame 5 is an auxiliary support structure of the fixing component. The U-shaped frame 5 is made of an elastic material and will deform when subjected to an external force and can return to its original state when the external force disappears, thereby generating an elastic force. The U-shaped frame 5 is connected to the support plate 44 through the cooperation of the bending part 51 and the clamping groove 52, thereby lifting the atomized water curtain outer spray pipe 1 to prevent the atomized water curtain outer spray pipe 1 from moving during operation. The extrusion parts 53 are installed on both sides of the U-shaped frame 5 and are located below the bending part 51. Through the extrusion action, the extrusion parts 53 can make the bending part 51 disengage from the clamping groove 52, thereby realizing the separation of the U-shaped frame 5 and the support plate 44. When it is necessary to disassemble or adjust the fixing component, by operating the extrusion parts 53 to apply an inward extrusion force to the bending part 51, the bending part 51 is disengaged from the clamping groove 52, thereby releasing the connection between the U-shaped frame 5 and the support plate 44. The U-shaped frame 5, as an auxiliary support structure of the fixing component, through the cooperation of the bending part 51 and the clamping groove 52 and the action of the extrusion parts 53, realizes the stable fixation and convenient disassembly of the atomized water curtain outer spray pipe 1. This provides convenience for the installation, maintenance, and adjustment of the coal mine nozzleless air flow purification device, and at the same time ensures the stability and reliability of the device during operation.

[0037] The working principle of the coal mine nozzleless air flow purification device provided by the present invention is as follows:

[0038] Atomization process: Water pressure is introduced through the downhole static water quick connector 13, causing water to spray out from the outer tube nozzle 16 of the atomized water curtain outer spray pipe 1. Wind pressure is introduced through the downwind gas quick connector 14, causing air flow to spray out from the inner tube nozzle 17 of the atomized water curtain compressed air inner drive pipe 11. After the water sprays out at the outer tube nozzle 16, it meets the air flow sprayed out from the inner tube nozzle 17, forming fine water mist particles in the atomization chamber. The formed water mist particles flow along with the air flow to adsorb and purify the dust and harmful gases in the air flow.

[0039] Cleaning process: During the cleaning process, the atomized water curtain outer spray pipe 1 can be separated from the fixing component. By pushing the grasping part 35, the second support ring frame 3 slides on the outside of the atomized water curtain outer spray pipe 1. At the same time, due to the mutual attraction between the N - pole magnet 22 and the S - pole magnet 32, the second support ring frame 3 can drive the first support ring frame 2 to move. During the movement, the inner tube outer wall brush 24 and the outer tube inner wall brush 25 respectively brush the outer wall of the atomized water curtain compressed air inner drive pipe 11 and the inner wall of the atomized water curtain outer spray pipe 1 to remove the attached water scale. The outer tube outer wall brush 34 cleans the outer wall of the atomized water curtain outer spray pipe 1. Finally, the back - flushing quick connector 15 is connected to the back - flushing system, and the water flow provided by the back - flushing system is introduced into the atomized water curtain outer spray pipe 1 to flush the water scale and impurities inside the pipe, keeping the inside of the pipe clean and unobstructed.

[0040] Fixing process: The mounting plate 4 is fixed at an appropriate position through the fixing holes 41 and the fixing rods 42. The atomized water curtain outer spray pipe 1 is lifted by the U - shaped frame 5 and connected to the support plate 44 through the cooperation of the bending part 51 and the card slot 52. At the same time, under the action of the return spring 47, the abutting plate 45 closely abuts against the outer top of the atomized water curtain outer spray pipe 1 to prevent it from moving. The return spring 47 provides a return force to ensure that the abutting plate 45 always maintains a closely abutting state. By operating the extrusion part 53, the bending part 51 can be disengaged from the card slot 52, realizing the separation of the U - shaped frame 5 from the support plate 44, which is convenient for disassembling or adjusting the fixing component.

[0041] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present invention.
